Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a deburring device for a manifold,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring device for an intake and exhaust manifold for an engine for removing burrs generated after completion of production of an intake or exhaust manifold installed to draw or discharge air or a mixed gas into a cylinder of an engine.

In general, all machines and mechanisms are made up of a combination of several parts, and the metal or non-metal parts used in them are processed according to the processing method suitable for them. The double metal parts are produced by non-cutting such as casting or forging, cutting such as turning or drilling, and burrs due to machining are inevitably generated.

Such a bur will not cause a problem in a device that does not require a large precision, but it may adversely affect the operation of the device in the case of a device requiring high precision, and in particular, it may damage the operator during transportation, storage and assembly of the component. Remove, i.e. deburring.

Particularly, all the components constituting the engine, which is the heart of the vehicle, are required to have high accuracy, and in particular, the burrs generated after completion of machining of the intake or exhaust manifold of the vehicle must be reliably removed.

The engine, which is an internal combustion engine, injects a mixture of fuel and air into the combustion chamber, and then pressurizes and combusts the mixture to generate power. In this process, depending on the condition of the mixture of fuel and air introduced into the combustion chamber, The combustion state of the mixed gas is changed. That is, when the fuel injected into the combustion chamber and the air are uniformly mixed, the volumetric efficiency is increased and the most powerful explosive force is obtained, thereby improving the performance of the engine.

An intake manifold is an intake manifold that draws air or mixed gas into the combustion chamber of such an engine. The exhaust manifold discharges the pressurized and combusted mixed gas to the outside of the combustion chamber. For example, in the " intake manifold cooling apparatus " of Japanese Laid-Open Patent Publication No. 10-1998-078634, intake manifolds and exhaust manifolds are mounted on the intake port and the exhaust port of the cylinder head of the engine, respectively. Such an intake or exhaust manifold is made of cast iron, aluminum alloy or steel pipe.

For example, in the case of the 'intake manifold manufacturing method for automobiles' of Japanese Patent Laid-Open Publication No. 10-1997-0064783, an aluminum material is used for casting by a casting mold method. The casting is carried out by using the upper and lower moldings, . When the casting or joining process is performed to manufacture the intake and exhaust manifold, a fin-like burr is formed along the cut surface or the joint surface of the mold.

The burr thus formed is removed by a grinding operation using a grinder or the like rotating at a high speed. Generally, these operations are performed by hand, so that the risk of safety accidents increases. Depending on the skill and sincerity of the worker, the efficiency of the production depends on the productivity of the worker. Therefore, the labor cost and the work time increase, There is a problem that is difficult to guarantee sex.

In order to solve such a problem, deburring devices have been recently used. Various deburring devices and robotic systems have been proposed through automation to increase the productivity while improving the efficiency of deburring work.

However, in the case of the above-described intake or exhaust manifold, as shown in FIG. 1, a plurality of cylindrical intake or exhaust pipes are branched from one cylindrical body and have a complicated structure, so that various shapes of deburring tools are required Therefore, there is a problem that the conventional deburring device can not be simply applied. Since the deburring operation takes a long time with only the end mill deburring tool having a small deburring area, the deburring operation is performed mainly on the curved surface portion, and the open front of each intake tube or exhaust pipe is formed by a large area grinding wheel deburring tool, The deburring operation is performed, and the somewhat flattened portion other than the end mill deburring tool and the grind wheel deburring tool operation is subjected to the deburring operation with the coin wheel deburring tool of the coin size.

In this case, when the deburring operation of the intake and exhaust manifold is performed manually, each deburring tool must be prepared and the operator must perform deburring work while replacing the respective deburring tools with the hand grinder, which has the problem of manual operation .

In case of performing the automatic deburring operation through the deburring device, a deburring device equipped with each deburring tool may be separately provided, or each deburring tool must be replaced on the basis of one deburring device. However, since the rotational torque and the number of revolutions for performing the deburring operation are different for each deburring tool, the spindle also needs to be replaced. Therefore, there is a problem that it is difficult to perform the deburring operation while actually replacing the deburring tool.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems described above and to solve the above problems in the prior art, and it is an object of the present invention to provide an exhaust manifold for a vehicle, The deburring tool of the present invention can be mounted on one deburring machining unit to easily perform a deburring operation, thereby improving productivity.

The deburring jig unit 200 approaches the deburring object W toward the deburring unit 300 to perform a deburring operation.

2 and 3, the deburring and machining unit 300 is installed in the main frame 100 adjacent to the deburring jig unit 200, and is fixed to the working end of the deburring jig unit 200. The burr formed on the surface of the deburring object W is removed. 10 to 12, a deburring operation is performed by a grind wheel deburring tool 331, and a flat deburring operation with a small area is performed by a coin wheel deburring tool 361, An inner circumferential surface deburring operation is performed and a curved surface or an intersecting surface deburring operation is performed by the end mill deburring tool 371. [

That is, the deburring jig unit 200 and the deburring unit 300 perform a linking operation based on the shape information of the deburring object W, which is performed by a controller (not shown). The control unit controls the operations of the deburring jig unit 200 and the deburring unit 300 by programming the deburring operation sequence based on the shape information of the deburring object W fixed to the deburring jig unit 200. [

1, each of the deburring tools for performing the deburring operation of the intake and exhaust manifold for the engine, which is a deburring object W having a complicated structure, is connected to one deburring unit 300 So that the deburring operation can be easily performed. Therefore, it is characterized in that each deburring tool mounted on the deburring machining unit 300 can perform various deburring operations in what manner through the structure and the coupling relation.

3, the deburring processing unit 300 includes a deburring frame 310, a front connecting frame 320, a grind wheel deburring unit 330, an upper connecting frame 340, a rotating frame 350, A coin wheel deburring unit 360 and an end mill deburring unit 370, and may further include a rotation operation cylinder 380 and a deburring tool rotation motor 390.

The deburring frame 310 is installed upright on the main frame 100. One end of the front connecting frame 320 is installed on the upper front surface of the deburring frame 310 and the other end is stepped forward . The grind wheel deburring unit 330 is fixed to the other end of the front connecting frame 320 in the X axis direction and a grind wheel deburring tool 331 is mounted at one end of the deburring jig unit 200. The upper connecting frame 340 is connected to the upper part of the grind wheel deburring part 330 in the Z axis direction and the rotating frame 350 is installed on the upper part of the upper connecting frame 340 so as to be rotatable about the Z axis The coin wheel deburring unit 360 and the end mill deburring unit 370 are mounted on the rotating frame 360 with a coin wheel deburring tool 361 and an end mill deburring tool 371 mounted thereon, And are installed so as to face opposite directions on one side and the other side.

Since the grind wheel deburring tool 331 performs a large area flat deburring operation, a large torque at a low speed is required. For example, it is preferable to set the grinding wheel deburring tool 331 at an allowable torque of 125Nm at a maximum of 3,000 RPM. Accordingly, the rotational power of the grind wheel rotating motor 334 is transmitted to the grind wheel spindle 333 through a power transmission means such as a gear connection or a belt pulley connection method, and the rotational speed of the grind wheel spindle 333 And the grind wheel deburring tool 331 is rotated with a large torque of the grinder wheel.

The coin wheel deburring tool 361 and the end mill deburring tool 371 are required to perform a deburring operation with a very small area compared to the grind wheel deburring tool 331 so that a high speed low torque is required. The torque is preferably set to about 48 Nm. Therefore, the rotational power of the coin wheel rotating motor 364 or the end mill rotating motor 374 is transmitted to the coin wheel spindle 362 through the coin wheel coupling 365 or the end mill coupling 375 without the need for separate power transmission means. To directly transmit the rotational force to the end mill spindle 362 or the end mill spindle 372 and to rotate each deburring tool with high-speed low torque with rotation of each spindle. Here, the coin wheel spindle housing 363 and the end mill spindle housing 373 each function to firmly maintain the concentricity of the coin wheel spindle 362 and the end mill spindle 372.

Meanwhile, the grind wheel deburring unit 330, the coin wheel deburring unit 360, and the end mill deburring unit 370 each propose a new operation method for smooth deburring. 3, 6 and 7, one end of the front connecting frame 320 of the deburring processing unit 300 is rotatably mounted on the upper front surface of the deburring processing frame 310 with respect to the Y axis. Accordingly, the deburring tool can perform deburring operations at various angles from various directions of the deburring tool in the X-axis direction to the Z-axis direction in various shapes of the deburring object W.

3, 8 and 9, the upper connecting frame 340 of the deburring machining unit 300 has a cylindrical lower portion rotatably coupled to the outer periphery of the grind wheel spindle housing 332, The deburring and machining unit 300 includes a piston rod 381 hinged to the upper connecting frame 340 and coupled to the grind wheel spindle housing 232 along the X- And a rotary operation cylinder 380 for rotating the upper connection frame 340 forward and upward at an angle of 90 degrees with respect to the upper connection frame 340. [ That is, since the height of the coin wheel deburring portion 360 and the end mill deburring portion 370 is high with respect to the grind wheel deburring portion 330, the deburring object W ). Accordingly, the work height of the coin wheel deburring unit 360 and the end mill deburring unit 370 is rotated 90 degrees forward of the grind wheel deburring unit 330 in order to align the work height of the coin wheel deburring unit 360 and the end mill deburring unit 370 with the grind wheel deburring unit 330.
