Description
Technical Field
The invention relates to a positioning auxiliary device of a hydraulic punching machine.
Background
The split hydraulic punching machine consists of a manual pump or an electric pump and a hydraulic punching working head, is connected by a hydraulic quick connector of an oil delivery hose, is reliable and quick in sealing, has no directional limitation during operation, and is convenient to assemble and disassemble, so that the split hydraulic punching machine is widely applied to transformer substation reconstruction and extension engineering. When the hydraulic punching machine is in operation, under the hydraulic power of the oil pump, the upper punch die (male die) compresses the reset spring to move downwards to act on the workpiece material, the material of the part to be punched is cut off under the shearing force action of the lower punch die (female die), after the punching is finished, the oil pump is returned, and the upper punch die is restored under the action of the reset spring. The domestic CH-70 and CH-60 split hydraulic punching device is specially used for punching metal plates such as angle irons, flat irons, copper plates and the like, is particularly suitable for field construction site operation in the industries such as electric power, construction and the like, and is heavy in material due to structural bearing requirements.
When a hydraulic punching machine is used in field operation, because the weight of the punching machine and a workpiece is large (the weight of the punching machine is about 25 kg, the weight of a large workpiece is 40-50 kg, and the length of the large workpiece can reach 6 meters), the hydraulic punching machine is generally directly placed on the ground for working in consideration of convenience and operability in actual operation, and the bottom die of the punching machine is about 10 cm away from the ground. Because the actual punching position cannot be seen intuitively, a punching machine operator can generate visual errors, cannot punch holes accurately at one time, needs to perform estimation, shallow punching and other steps to assist in judging the actual punching position, has low punching efficiency and long time consumption, is easy to generate unqualified phenomena such as a 'gourd hole', and has lower actual working efficiency due to the influence of the size and weight of a larger workpiece.
When the traditional hydraulic punching machine is used for punching, the punching position cannot be determined at one time, the position of a workpiece to be punched is marked according to the marking pen, prediction is carried out, the workpiece to be punched is placed on the lower punching die of the punching machine, the relative positions of the marking and the upper punching die are observed from the obliquely upper side, one-time shallow punching is carried out, and the workpiece to be punched is formally punched after corresponding adjustment is carried out according to the comparison between the shallow punching mark and the marking position. Sometimes, the workpiece is required to be repeatedly adjusted to be barely aligned, deviation exists between the punched hole and the expected position, and the fixed connecting piece is required to be repeatedly adjusted when the workpiece is connected.

Description of the embodiments
The accurate positioning auxiliary device of the hydraulic punching machine comprises a left stainless steel universal pipe 3 and a right stainless steel universal pipe 3 which are welded on a base 2 of the hydraulic punching machine 1, wherein the end parts of the left stainless steel universal pipe and the right stainless steel universal pipe are respectively provided with a linear laser 4, and a linear laser power supply line is arranged in the universal pipe; when in operation, the laser emitted by the linear laser is a sector, and the laser is projected on a plane to be expressed as a straight line; the two in-line lasers are placed at a certain included angle in the horizontal direction, and are projected on a plane to form a cross line, and the two in-line lasers are adjusted to vertically project.
The in-line laser light source is a low-power consumption 3V voltage, 5mw power and 650nm light source.
The invention improves the punching precision to the greatest extent on the premise of not influencing the normal use of the punching machine. When in operation, the laser emitted by the linear laser is a sector, and the laser is projected on a plane to be expressed as a straight line. The double-line laser is placed at a certain included angle in the horizontal direction, and then projected on a plane to be represented as a cross line. Because the workpieces have a certain thickness in actual use, and the thickness difference between different workpieces is large, the influence of the difference in the thickness of the workpieces on the positioning precision must be considered. The double-line laser is adjusted to be vertically projected, so that the problem of positioning accuracy reduction caused by the thickness of a workpiece can be solved, and the workpiece positioning device can be suitable for positioning workpieces with different thicknesses only by one-time calibration, and human visual errors are eliminated. After the focal length of the laser is adjusted, the formed laser cross line mark is clear and high in brightness, is harmless to human eyes, can ensure that the mark is clear and visible no matter indoors and outdoors, and can also be used for normally carrying out accurate positioning assistance under strong light. The low-power-consumption in-line laser can be driven by only using an AA battery, has low energy consumption and long continuous service time, and is suitable for being used on a construction site.
The stainless steel universal pipe has the characteristics of flexible steering, large amplitude, certain fixity and the like, and is low in cost and durable in use. The stainless steel universal pipe is used as a laser bracket, so that any angle adjustment of a laser can be realized, the hydraulic punching machine is suitable for hydraulic punching machines of different models, and the hydraulic punching machine is convenient to operate and accurate in positioning. Meanwhile, the linear laser power supply circuit is arranged in the universal pipe, so that the internal circuit can be effectively protected from being interfered by the external environment, and the possible damage of the construction site environment to the power supply circuit is prevented.
