Description

Technical Field

[0001] The utility model relates to the technical field of speed reducer end cover processing, and particularly relates to an automatic processing device for a speed reducer end cover. Background Art

[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a working machine, and plays a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. The end cover of the speed reducer is an important component of the speed reducer.

[0003] At present, the existing speed reducer end cover processing device generally includes a CNC lathe body. A chuck is installed on the side wall of the CNC lathe body, and a turning device and a rotating device are installed on the upper end of the CNC lathe body. When turning the speed reducer end cover, the speed reducer end cover is inserted and sleeved outside the chuck. The chuck is started to drive the jaws of the chuck to press against the inner side wall of the speed reducer end cover, so as to fix the speed reducer end cover. The rotating device is started to drive the speed reducer end cover to rotate, and the turning device is started, so that the speed reducer end cover can be turned.

[0004] In the above solution, when the existing technology fixes the speed reducer end cover through the chuck, it is necessary for the staff to insert and sleeve the speed reducer end cover outside the chuck. However, when the staff inserts and sleeves the speed reducer end cover outside the chuck, it cannot be guaranteed that the speed reducer end cover is parallel to the chuck, which is likely to cause the speed reducer end cover to be fixed on the chuck obliquely, thus affecting the turning accuracy and easily causing the generation of defective products. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the existing technology and provide an automatic processing device for a speed reducer end cover. By providing a positioning component, the speed reducer end cover is parallel to the inner support fixture, solving the problem that the existing technology is likely to cause the speed reducer end cover to be fixed on the inner support fixture obliquely, thus not affecting the turning accuracy and eliminating the generation of defective products.

[0006] The solution of the utility model to solve the technical problem is:

[0007] An automatic processing device for a speed reducer end cover includes a machine body. A rotating arm is rotatably connected to the side wall of the machine body. An inner support fixture is fixed inside the rotating arm. A positioning component is provided at one end of the rotating arm, and a rotating component is provided at the other end of the rotating arm. A guiding channel is fixed to the side wall of the machine body. A sliding plate is slidably connected inside the guiding channel. A moving mechanism is provided at the upper end of the sliding plate. The moving mechanism includes a moving component and a lifting component. A tool rest is provided at the upper end of the lifting component. Two tool heads are fixed to the side wall of the tool rest. A translation component is provided on the side wall of the machine body.

[0008] When the end cover of the speed reducer needs to be turned, insert and sleeve the end cover of the speed reducer on the outside of the inner support fixture, and make the bottom end of the end cover of the speed reducer abut against the top end of the positioning component, so that the end cover of the speed reducer is arranged parallel to the inner support fixture. Start the inner support fixture, and make the clamping rod of the inner support fixture press against the inner side wall of the end cover of the speed reducer, so as to fix the end cover of the speed reducer. Start the rotating component to drive the rotating arm to rotate, thereby driving the end cover of the speed reducer to rotate. Start the translation component to drive the sliding plate to move. The movement of the sliding plate drives the moving component and the lifting component to move, thereby driving the tool head to move to the required position. Start the moving component and the lifting component to drive the tool head to move and simultaneously drive the tool head to lift, so as to turn the end cover of the speed reducer through the tool head.

[0009] By providing the positioning component, the end cover of the speed reducer is arranged parallel to the inner support fixture, solving the problem in the prior art that the end cover of the speed reducer is easily fixed on the inner support fixture obliquely, thus not affecting the turning accuracy and preventing the generation of defective products.

[0010] The utility model is further provided that: the positioning component includes three positioning plates fixed at the end of the rotating arm. The three positioning plates are symmetrically arranged at the center, and air outlet holes are formed at the ends of the positioning plates.

[0011] Through the above technical solution, when the end cover of the speed reducer needs to be arranged parallel to the inner support fixture, compressed air is introduced into one end of the plurality of air outlet holes, and the compressed air is ejected from the other end of the air outlet holes. Insert and sleeve the end cover of the speed reducer on the outside of the inner support fixture, and make the bottom end of the end cover of the speed reducer abut against the end of the positioning plate. When the end cover of the speed reducer is arranged parallel to the inner support fixture, the end of the end cover of the speed reducer just blocks all the air outlet holes, so that no air flow is ejected, ensuring that the end cover of the speed reducer is arranged parallel to the inner support fixture. When the end cover of the speed reducer is not arranged parallel to the inner support fixture, the end of the end cover of the speed reducer cannot completely block all the air outlet holes, so that compressed air is ejected, which can remind the staff to adjust the end cover of the speed reducer, thus ensuring that the end cover of the speed reducer is arranged parallel to the inner support fixture.

[0012] The utility model is further provided that: the rotating component includes a motor fixed on the side wall of the machine body, and the output end of the motor is fixedly connected to the end of the rotating arm.

[0013] Through the above technical solution, when the end cover of the speed reducer needs to be driven to rotate, after fixing the end cover of the speed reducer through the inner support fixture, start the motor to drive the rotating arm to rotate, thereby driving the end cover of the speed reducer to rotate.

[0014] The utility model is further provided that: the moving component includes a support plate fixed on the upper end of the sliding plate. A first servo electric cylinder is fixed on the upper end of the support plate, and the end of the piston rod of the first servo electric cylinder is fixedly connected with a mounting frame. The lifting component is arranged on the upper end of the mounting frame.

[0015] Through the above technical solution, when it is necessary to drive the tool head to move, the first servo electric cylinder is started to drive the mounting frame to move. The movement of the mounting frame drives the lifting assembly to move, and the movement of the lifting assembly drives the tool rest to move, so as to drive the tool head to move.

[0016] The utility model is further arranged as follows: the lifting assembly includes a second servo electric cylinder fixed to the lower end of the mounting frame. Two sliding rods are fixed to the upper end of the mounting frame. The tool rest is simultaneously inserted into the two sliding rods, and the lower end of the tool rest is fixed to the end of the piston rod of the second servo electric cylinder.

[0017] Through the above technical solution, when it is necessary to drive the tool head to lift, the second servo electric cylinder is started to drive the tool rest to lift, so as to drive the tool head to lift. At the same time, by providing two sliding rods, the tool rest can be driven to move smoothly and stably, thereby improving the stability of the tool rest during lifting.

[0018] The utility model is further arranged as follows: the translation assembly includes two guide rods symmetrically fixed to the side wall of the sliding plate. The guide rods are inserted into the side wall of the machine body. A third servo electric cylinder is fixed to the side wall of the machine body, and the end of the piston rod of the third servo electric cylinder is fixed to the side wall of the sliding plate.

[0019] Through the above technical solution, when it is necessary to drive the sliding plate to move, the third servo electric cylinder is started, so as to drive the sliding plate to move. At the same time, by providing two guide rods, the sliding plate can be driven to move smoothly and stably, thereby improving the stability of the sliding plate during movement.

[0020] The utility model is further arranged as follows: a compression spring is inserted on the side wall of the piston rod of the first servo electric cylinder. One end of the compression spring is fixed to the side wall of the mounting frame, and the other end of the compression spring is fixed to the side wall of the support plate.

[0021] Through the above technical solution, by providing a compression spring, the mounting frame can be driven to move smoothly and stably, thereby improving the stability of the mounting frame during movement.

[0023] Compared with the prior art, by providing a positioning component, the reducer end cover and the inner support fixture are arranged in parallel, solving the problem in the prior art that the reducer end cover is easily inclined and fixed on the inner support fixture, so that the turning accuracy is not affected and the generation of defective products is eliminated.
