Conventionally, steps or annular grooves are machined by transferring to a numerical control machine tool after all working procedures are finished on a special waterwheel type valve machine, so that machining efficiency is low, and machining precision is difficult to guarantee due to the fact that secondary clamping exists.
Disclosure of Invention
The invention aims to solve the problems in the prior art, provides a processing head for a power head, and solves the problems of low processing efficiency and poor processing precision.
The purpose of the invention can be realized by the following technical scheme:
the machining head comprises a mounting seat and a drill bit, wherein the mounting seat can be connected to the power head and driven by the power head to rotate, the drill bit is connected to the mounting seat and has the same central line with the mounting seat, the machining head is characterized in that a cutter which can be close to or far away from the drill bit is connected to the mounting seat in a sliding mode along the direction perpendicular to the drill bit, and the cutting edge of the cutter faces the side portion of the drill bit.
The mounting seat is connected at the end part of the power head, and the power head is arranged on the shell of the special waterwheel type valve machine. In an initial state, the cutter is far away from the side of the drill bit, when a rotary disc in the special waterwheel type valve rotates until a workpiece is opposite to the power head, the power head approaches the workpiece and drives the mounting seat to rotate through the internal driving mechanism, and the drill bit drills on the workpiece along with the continuous approach of the power head to the workpiece (at the moment, the cutter is far away from the side of the drill bit and cannot contact the workpiece). After the drill hole is drilled to a set depth, the power head does not move any more, but the mounting seat still keeps a rotating state, then the cutter is directly controlled to approach the drill bit, and after the cutting edge of the cutter is contacted with the side part of the workpiece, corresponding processing such as turning steps or turning grooves is carried out on the side part of the workpiece in the continuous rotation of the mounting seat. Through the arrangement, the machining head can directly machine the outer side of the workpiece after drilling the hole, the machining efficiency is well improved, and the machining precision is higher because no secondary clamping is carried out. In addition, the drill bit is kept inserted into the workpiece in the machining process of the cutter, when the wall of the workpiece becomes thinner after the hole is drilled, a certain support can be formed by the drill bit when the cutter drives a step or a groove on the outer side of the workpiece, and the workpiece is prevented from being broken or deformed.
In the processing head of using on foretell power head, the mount pad on be fixed with the connecting block through the fastener, the drill bit is fixed on the connecting block, be equipped with on the mount pad with drill bit looks vertically slider, the cutter is fixed on the slider, runs through along the slip direction of slider on the connecting block and is provided with the groove of stepping down, the slider passes the groove of stepping down.
Through the arrangement, normal drilling work of the workpiece can be guaranteed, and meanwhile the sliding block can be used for driving the cutter to be directly close to the workpiece to process the outer side of the workpiece after drilling is finished, so that secondary clamping is omitted to improve the processing efficiency and guarantee the processing precision. And because the drill bit is fixed on the connecting block, the existing exhibition tool bit can be directly adopted for use during actual production (the existing exhibition tool bit comprises a mounting seat and a sliding block), and only hole sites for fixing the connecting block by matching with a fastener are correspondingly arranged on the exhibition tool bit.
In the processing head for the power head, the cutter comprises a cutter rest fixed on the sliding block and a cutter blade which is detachably connected to the cutter rest and has a certain thickness, the cutter blade is perpendicular to the mounting seat, and a processing part capable of processing steps and/or grooves on the side part of the workpiece when the mounting seat rotates is arranged on the cutting edge of the cutter blade.
The blade can be dismantled and connect on the knife rest for the staff can change the cutter according to the shape that the work piece outside needs processed (for example, the number of processing the step simply, processing groove and groove simply, or existing step and slotted etc.), improves the suitability. Moreover, the blade has a certain thickness, is not a conventional thin blade, can easily process a workpiece along with the rotation of the mounting seat when contacting the workpiece, and is not easy to deform in the processing process so as to ensure the processing precision. In addition, the shape of the processing part can be designed according to the number of the grooves or the steps which are actually required to be processed, so that the processing such as a plurality of grooves, a plurality of steps or the combination of the steps and the grooves can be completed at one time, and the processing efficiency is further improved.
In the processing head of using on foretell power head, the knife rest be cubic, the side that the knife rest and connecting block are close to each other is the plane mutually perpendicular with slider sliding direction, the knife rest exceeds the connecting block along drill bit axis direction, the part that the knife rest exceeds the connecting block has the lug near a side of connecting block, the blade is fixed on the lug and is close to a side of connecting block mutually perpendicular with the knife rest, the blade of blade stretches out the lug and is close to outside one side of connecting block.
The blade is fixed on the part of the tool rest higher than the connecting block, so that the connecting block can be prevented from being touched in the process of machining the outer side of the workpiece, and meanwhile, the machining depth of the workpiece by the tool can be prevented from being influenced by the connecting block. Meanwhile, the mounting seat is not too large generally, one side surface of the tool rest, which is close to the connecting block, is set to be a plane which is perpendicular to the sliding direction of the sliding block, and the depth range which can be processed by the tool can be expanded as far as possible within an effective range.
In the machining head for the power head, the surface of the sliding block is provided with a guide groove along the sliding direction, the tool rest is provided with a guide block embedded in the guide groove, the tool rest is provided with a plurality of waist-shaped adjusting holes in a penetrating manner, and the tool rest and the sliding block are fixed through fastening screws which penetrate through the waist-shaped adjusting holes and are in threaded connection in the sliding block.
When the tool is used, the slide block is only used for controlling the processing depth of the tool on a workpiece, and the moving distance of the slide block is preset. If the maximum distance between the cutting edge of the tool and the drill bit (i.e., the tool is driven by the slider to be far away from the drill bit) is too small or too large, the machining depth of the tool on the workpiece is not accurate. Therefore, the distance between the cutting edge of the cutter and the drill bit can be adjusted under the condition that the sliding block is kept motionless through the arrangement of the waist-shaped adjusting holes, and therefore the machining precision is guaranteed.
In the processing head for the power head, the connecting block is provided with a connecting hole, the handle part of the drill bit is inserted into the connecting hole, the side part of the handle part of the drill bit is provided with a planar stop surface, and the connecting block is in threaded connection with a locking screw capable of pushing against the stop surface.
Compared with the prior art, the processing head used on the power head integrates the drill bit and the cutter on the mounting seat, and can directly process the outer side of the workpiece after drilling holes by the movement of the cutter along the vertical direction of the drill bit, thereby well improving the processing efficiency and having higher processing precision because no secondary clamping is carried out. Meanwhile, the drill can be directly used for supporting the workpiece in the machining process of the cutter, so that the workpiece is prevented from being broken or deformed.
