Abstract
Description
Technical Field
[0001] This application relates to the field of speed reducer processing technology, specifically a speed reducer grinding device. Background Technology
[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. During the production of speed reducers, the speed reduction structure needs to be polished.
[0003] However, existing grinding devices generally require manual handling, which makes it very troublesome for workers to operate. Manual operation can easily lead to insufficient grinding precision, and manually holding the reducer makes it difficult to adjust the grinding position after the reducer is clamped, making the grinding process quite complicated. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a speed reducer grinding device that frees up the operator's hands, prevents insufficient grinding precision, facilitates adjustment of the grinding position after the speed reducer is clamped, and improves the ease of adjustment. This solves the problems of existing devices generally requiring manual handling for operation, which is cumbersome, easily leads to insufficient grinding precision, and makes it difficult to adjust the grinding position after the speed reducer is clamped, resulting in a complicated grinding process.
[0005] To achieve the above objectives, this application provides the following technical solution: a speed reducer grinding device, comprising a worktable and a telescopic rod, wherein a motor is fixedly connected to the right side of the worktable, a threaded rod is fixedly connected to the output shaft of the motor, a sliding block is threadedly connected to the outer surface of the threaded rod, a mounting plate is slidably connected to the outer surface of the sliding block, the bottom surface of the mounting plate is fixedly connected to the upper surface of the worktable, a mounting plate is fixedly connected to the upper surface of the sliding block, the bottom surface of the telescopic rod is fixedly connected to the upper surface of the mounting plate, a sliding block is slidably connected to the inner wall of the mounting plate, the output end of the telescopic rod is fixedly connected to the right side of the sliding block, a placement platform is fixedly connected to the upper surface of the sliding block, a bidirectional screw is rotatably connected to the inner wall of the placement platform, and two clamping members are threadedly connected to the outer surface of the bidirectional screw.
[0006] The above solution aims to free the operator's hands, eliminating the need for manual handling and preventing insufficient grinding precision. It also improves the ease of adjustment and reduces the complexity of the grinding process. The grinding machine is placed on the surface of the platform, and rotating the bidirectional screw moves the two clamping parts, thus clamping the reducer. This frees the operator's hands, preventing insufficient grinding precision. A motor is installed on the right side of the worktable, and a threaded rod is mounted on the output shaft of the motor. A sliding block is connected to the threaded rod. The motor rotates the threaded rod, causing the sliding block to move. The sliding block moves the mounting plate, which in turn moves the upper-clamped reducer and telescopic rod. The connection between the telescopic rod and the sliding block allows the platform and the upper reducer to move, facilitating adjustment of the grinding position after the reducer is clamped, thus improving the ease of adjustment.
[0007] Furthermore, a guide rod is fixedly installed on the outer surface of the placement platform, and the inner wall of each clamping member is slidably connected to the outer surface of the guide rod.
[0008] The above scheme involves installing a guide rod on the outer surface of the placement platform and connecting the surface of the guide rod to the inner wall of the clamping component, setting it as a sliding connection. The guide rod is used to limit the clamping component and ensure its stability during relative movement.
[0009] Furthermore, the clamping member is arc-shaped, and each clamping member has a rubber pad on the side that is close to each other.
[0010] With the above solution, the clamping parts are arc-shaped. Two clamping parts can clamp reducers of different sizes, improving applicability. Rubber pads are placed on the sides of the clamping parts that are close to each other. By placing rubber pads in contact with the reducers, damage to the reducer surface caused by rigid clamping can be prevented. In addition, the rubber pads can increase friction and ensure stability after clamping.
[0011] Furthermore, the other end of the threaded rod is rotatably connected to the inner wall of the workbench, and a mounting bracket is fixedly connected to the upper surface of the workbench.
[0012] The above scheme connects the other end of the threaded rod to the inner wall of the workbench as a rotatable connection to limit the movement of the threaded rod. The mounting bracket is installed on the upper surface of the workbench as a fixed connection, and the workbench supports the mounting bracket.
[0013] Furthermore, a top plate is fixedly mounted on the upper surface of the mounting bracket.
[0014] The above method involves installing the top plate on the upper surface of the mounting frame and fixing it with bolts, thereby achieving support and installation of the top plate.
[0015] Furthermore, a vertical pole is fixedly connected to the upper surface of the mounting bracket, and a sliding plate is slidably connected to the outer surface of the vertical pole.
[0016] The above scheme sets the upright on the upper surface of the mounting frame as a fixed connection to achieve the installation of the upright. The sliding plate is installed on the surface of the upright as a sliding connection, and the side of the sliding plate slides with the inner side wall of the mounting frame to achieve the limiting of the sliding plate.
[0017] Furthermore, a second motor is fixedly connected to the bottom surface of the sliding plate, and a grinding head is fixedly installed on the output shaft of the second motor.
[0018] The above scheme involves mounting motor 2 on the bottom surface of the sliding plate, enabling the sliding plate to move. The movement of the sliding plate allows motor 2 to move, and the grinding head is mounted on the output shaft of motor 2 and fixed. Motor 2 enables the grinding head to rotate, thereby completing the grinding operation.
[0019] Furthermore, a second telescopic rod is fixedly installed on the inner wall of the top plate, and the output end of the second telescopic rod is fixedly connected to the upper surface of the sliding plate.
[0020] With the above solution, a second telescopic rod is installed on the inner wall of the top plate, and the output end of the second telescopic rod is connected to the sliding plate as a fixed connection. The extension and retraction of the second telescopic rod allows the second motor and the grinding head to be raised and lowered, making it easy to adjust the height of the grinding head.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This gear reducer grinding device comprises components such as a telescopic rod, a threaded rod, a sliding block, a sliding block, and a clamping component. The gear reducer is clamped onto a placement table via the bidirectional threaded rod and clamping component, freeing the operator's hands and eliminating the need for manual handling, thus preventing insufficient grinding precision. A motor rotates the threaded rod, which in turn moves the sliding block, the mounting plate, and the telescopic rod. The telescopic rod then moves the sliding block and the placement table, allowing the clamped gear reducer to be moved to adjust its grinding position, improving ease of adjustment. The telescopic rod raises and lowers the sliding plate, which in turn raises and lowers the motor and the grinding head, facilitating adjustment of the grinding head's height.

[0038] Please see Figure 1 , Figure 2 and Figure 3 A telescopic rod 17 is fixedly installed on the inner wall of the top plate 16. The output end of the telescopic rod 17 is fixedly connected to the upper surface of the sliding plate 15. The telescopic rod 17 is installed on the inner wall of the top plate 16, and the output end of the telescopic rod 17 is connected to the sliding plate 15 in a fixed connection. The extension and retraction of the telescopic rod 17 allows the motor 18 and the grinding head 19 to be raised and lowered, which facilitates the adjustment of the height of the grinding head 19.
[0039] This embodiment of a speed reducer grinding device includes components such as a telescopic rod 2, a threaded rod 4, a sliding block 6, a sliding block 8, and a clamping member 11. The speed reducer is clamped onto a placement table 9 via a bidirectional screw 10 and the clamping member 11, freeing the operator's hands and preventing manual handling, thus ensuring sufficient grinding precision. A motor 3 rotates the threaded rod 4, which in turn moves the sliding block 6, the mounting plate 7, and the telescopic rod 2. The telescopic rod 2 allows the sliding block 8 and the placement table 9 to move, enabling the clamped speed reducer to adjust its grinding position and improving ease of adjustment. The telescopic rod 17 allows the sliding plate 15 to rise and fall, which in turn allows the motor 18 and the grinding head 19 to rise and fall, facilitating the adjustment of the grinding head's height.
[0040] It should be noted that both telescopic rod 12 and telescopic rod 27 are electric telescopic rods. The right side of mounting plate 27 has a protruding fixing plate, which can be connected to telescopic rod 12 so that when mounting plate 27 moves, telescopic rod 12 can move with it.
[0041] The working principle of the above embodiments is as follows:
[0042] When grinding the speed reducer, first place the speed reducer to be ground on the placement table 9, then rotate the double-acting screw 10 to move the clamping parts 11 relative to each other, so that the speed reducer can be clamped on the placement table 9, freeing the operator's hands and preventing manual handling, thus preventing insufficient grinding precision. Activating the telescopic rod 17 causes the sliding plate 15 to descend, which in turn causes the motor 18 and grinding head 19 to descend, allowing the speed reducer to be ground through the motor 18 and grinding head 19. When the grinding position needs to be adjusted, the screw rod 4 is rotated by the motor 3, which in turn causes the sliding block 6, mounting plate 7, and telescopic rod 2 to move, realizing the left and right movement of the speed reducer. The telescopic rod 2 allows the sliding block 8 and placement table 9 to move, realizing the forward and backward movement of the speed reducer, thus allowing the clamped speed reducer to move in different positions, facilitating the adjustment of the grinding position after clamping the speed reducer and improving the convenience of adjustment.
