Description

Technical Field

[0001] This invention belongs to the technical field of deburring devices, specifically relating to a deburring device and method for the end face of an elevator guide rail bracket. Background Technology

[0002] The elevator guide rail bracket end face deburring device is an automated equipment specifically designed for removing burrs from the processing end and cut end face of elevator guide rail brackets.

[0003] Patent publication number CN221159695U relates to a deburring device for angle steel, including a support platform and an operating device. A diesel tank is installed on the lower surface of the support platform, and a pipe is connected to the left side of the diesel tank. A tall wooden frame is set at the right end of the support platform surface, and an anti-slip plate is placed on the tall wooden frame. A longitudinal grinding device is set in the center of the anti-slip plate, and a grinding disc is set in the middle of the longitudinal grinding device. A main drive motor is installed on the lower surface of the tall wooden frame, and a connecting pipe is set on the left side of the main drive motor. A transverse grinding device is set at the left end of the support platform surface, and a grinding column is set in the transverse grinding device. The advantages of this patent are: the grinding device can be adjusted in direction, the placement of the self-rotating device makes this device applicable to other types of angle steel, and the setting of its fuel injector greatly reduces the probability of burrs being left behind.

[0004] The aforementioned patent allows for self-adjustment of the grinding direction, which can improve the deburring efficiency of angle steel workpieces. However, when deburring the end faces of elevator guide rail brackets, each guide rail bracket needs to be deburred separately at both ends, which is cumbersome, time-consuming, and labor-intensive. If multiple guide rail brackets are deburred simultaneously, it is necessary to ensure that each end face is precisely aligned; otherwise, uneven grinding of the end faces and incomplete burr removal may occur. Summary of the Invention

[0005] Therefore, it is necessary to provide a deburring device and method for the end face of elevator guide rail brackets to address the shortcomings of existing technologies and solve the problem of tedious grinding of the end face of a single guide rail bracket.

[0006] To solve the above problems, this application adopts the following technical solution: One objective of this application is to provide a deburring device for the end face of an elevator guide rail bracket, comprising a processing table, two sets of abrasive wheel polishing devices fixedly mounted on the top of the processing table, a drive module fixedly mounted on the top of the processing table, the drive module including a linear drive device and an optical axis guide rail, and further comprising: a sliding platform, the sliding platform being slidably mounted on the top of the optical axis guide rail, the bottom of the sliding platform being fixedly connected to the drive end of the linear drive device, the linear drive device being used to drive the sliding platform to smoothly reciprocate along the optical axis guide rail; a support frame, the support frame being fixedly mounted on the top of the sliding platform, the support frame having two guide holes on its top; and an electric push rod, which... The electric push rod is fixedly inserted through the center of the top of the support frame; a bearing plate is fixedly installed at the output end of the electric push rod, which drives the bearing plate to perform vertical lifting and lowering movements; two elastic telescopic rods are fixedly inserted through the top two sides of the bearing plate, and the circumferential surfaces of the two elastic telescopic rods are respectively in contact with the inner walls of two guide holes. When the electric push rod is activated, the output end of the electric push rod drives the bearing plate to descend smoothly to the set position, and the bearing plate drives the elastic telescopic rods to move down synchronously along the guide holes; a pressure plate is fixedly installed at the telescopic end of the elastic telescopic rod, which is used to press down and fix the guide rail bracket.

[0007] In some embodiments, the top of the sliding platform is provided with two sets of clamping mechanisms. Each clamping mechanism includes a fixed base, a screw, a knob, and a positioning plate. The fixed base is fixedly installed on the top of the sliding platform. The surface of the fixed base has an internal threaded through hole adapted to the screw. The screw is threaded into the internal threaded through hole. The knob is fixedly installed at one end of the screw. The positioning plate is rotatably installed at the other end of the screw. The bottom of the positioning plate is in contact with the top of the sliding platform. Manually rotating the left knob causes the screw to rotate synchronously along the internal threaded through hole of the fixed base, driving the left positioning plate to translate to the right.

[0008] In some embodiments, two sets of the grinding wheel polishing devices are symmetrically arranged on both sides of the top of the processing table. In the symmetrically arranged grinding wheel polishing devices, two high-speed rotating grinding wheels are synchronously contacted with the end faces of the guide rail brackets to achieve synchronous deburring of the end faces. Two sets of the clamping mechanisms are symmetrically arranged on both sides of the top of the sliding platform.

[0009] In some embodiments, a protective cover is fixedly installed on the surface of the grinding wheel polishing device. The protective cover is used to block metal debris from splashing during the deburring process. During the deburring process, the protective cover can effectively block the splashing metal debris.

[0010] In some embodiments, the top of the processing table is provided with a calibration device for automatically calibrating the end face of the guide rail bracket. The calibration device is provided with a limit protection device for improving the standardization of operation. The calibration device includes a mounting frame, a guide rod, a clamping plate, an arc-shaped block, a straight rod, a sleeve, a linkage plate, a rectangular plate, and rollers. During the process of the electric push rod output end driving the bearing plate to move downward, the bottom of the bearing plate contacts the top of the linkage plate, thereby driving the linkage plate to move downward synchronously. The mounting frame is fixedly installed on the top of the processing table. The guide rod slides through the surface of the mounting frame. The clamping plate is fixedly installed on the end of the guide rod near the electric push rod. The arc-shaped block is fixedly installed on the side of the clamping plate near the mounting frame. The straight rod is fixedly installed on the surface of the mounting frame. The sleeve slides on the circumferential surface of the straight rod. The linkage plate is fixedly installed on the circumferential surface of the sleeve. The rectangular plate is fixedly installed on the circumferential surface of the sleeve. The inner wall of the rectangular plate is rotatably penetrated by a rotating shaft. The rollers are fixedly installed on the circumferential surface of the rotating shaft.

[0011] In some embodiments, a first spring is provided between the guide rod and the mounting frame. The guide rod compresses the first spring and causes it to undergo elastic deformation. A second spring is provided between the sleeve and the mounting frame. The sleeve pulls down the second spring and causes it to undergo elastic deformation. A rectangular limiting groove is provided at the top of the rectangular plate.

[0012] In some embodiments, the limiting protection device includes a fixed plate, a limiting plate, a circular plate, a reset spring, a T-shaped plate, and a triangular block. The fixed plate is fixedly installed on the side of the mounting frame away from the straight rod. The limiting plate is slidably installed on the inner wall of the fixed plate and slides through the surface of the mounting frame. The circular plate is fixedly installed on the side of the limiting plate away from the straight rod. The reset spring is disposed between the fixed plate and the circular plate. The T-shaped plate is fixedly installed on the surface of the circular plate. The triangular block is fixedly installed at the bottom of the rectangular plate. When the sleeve moves the rectangular plate downward, the rectangular plate moves the triangular block downward synchronously. The side of the limiting plate away from the circular plate has an arc surface.

[0013] In some embodiments, a circular tube is fixedly installed on the side of the fixed plate near the circular plate, and a damping ring is provided on the circumferential surface of the circular plate. The damping ring is in contact with the inner wall of the circular tube. The circular plate moves inside the circular tube, and the damping ring on its circumferential surface forms frictional damping with the inner wall of the circular tube, so that the operator needs to apply a stable pulling force when pulling the T-shaped plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention involves a positioning plate that fits against the outer wall of the guide rail bracket and continuously applies a pushing force, causing a set of four guide rail brackets to fit together and eliminate gaps. The positioning plates on both sides achieve double-sided limiting and lateral clamping of the guide rail brackets, effectively eliminating gaps and enabling simultaneous one-time positioning of multiple C-shaped steel structure guide rail brackets. This improves the processing efficiency of batch deburring operations. At the same time, the pressure plate applies stable downward pressure to the top of the guide rail brackets, firmly pressing the guide rail brackets onto the top of the sliding platform. By using the pressure plate to stably press a set of guide rail brackets together, and in conjunction with the positioning plate, the deburring of both ends of four guide rail brackets can be completed at one time, significantly shortening the deburring time of a single guide rail bracket.

[0015] This invention involves rotating a knob to drive the positioning plate to move horizontally, separating the positioning plate from the outer wall of the guide rail bracket. The operator can then take out the processed guide rail brackets one by one. Through the flexible use of the positioning plates on both sides, the positioning constraint can be quickly released after deburring, making it convenient for the operator to pick up and put down the guide rail brackets and improving the overall efficiency of clamping, positioning and unloading.

[0016] In this invention, the clamping plate contacts the end face of the guide rail bracket and applies a stable thrust. The clamping plate contacts the end face of the guide rail bracket and applies a stable thrust. In conjunction with the clamping plate on the other side that moves synchronously, the end faces of both ends of the guide rail bracket are automatically aligned and calibrated. At the same time, the first spring rebounds and drives the guide rod and clamping plate to reset to the initial position. Through the automatic reset of the first spring, the clamping plate can quickly retract after calibration, providing a safe clearance space for the movement of the guide rail bracket, avoiding friction between the end face of the guide rail bracket and the clamping plate, and ensuring the quality of end face processing.

[0017] This invention involves a limiting plate that fits into a rectangular limiting groove on a rectangular plate, creating a blocking constraint on the upward movement of the rectangular plate. The limiting plate automatically blocks and limits the downward movement of the rectangular plate, ensuring that the clamping plate remains in a non-collision state when the sliding platform moves the guide rail bracket to the right for deburring. At the same time, the damping ring forms frictional damping with the inner wall of the round tube, requiring the operator to apply a stable pulling force when pulling the T-shaped plate. Through the frictional resistance between the damping ring and the inner wall of the round tube, combined with the elastic resistance of the reset spring, the limiting plate is ensured to move under standardized and controllable manual operation, effectively improving operational safety.

Detailed Implementation

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1 - Figure 9As shown, one embodiment of the present invention is: a deburring device for the end face of an elevator guide rail bracket, comprising a processing table 1, two sets of grinding wheel polishing devices 2 fixedly installed on the top of the processing table 1, a drive module 3 fixedly installed on the top of the processing table 1, the drive module 3 including a linear drive device and an optical axis guide rail, and further comprising: a sliding platform 4, the sliding platform 4 being slidably installed on the top of the optical axis guide rail, the bottom of the sliding platform 4 being fixedly connected to the drive end of the linear drive device, the linear drive device being used to drive the sliding platform 4 to smoothly reciprocate along the optical axis guide rail; a support frame 5, the support frame 5 being fixedly installed on the top of the sliding platform 4, the support frame 5 having two guide holes on its top; and an electric push rod 6. 6 is fixedly inserted through the center of the top of the support frame 5; bearing plate 7 is fixedly installed at the output end of the electric push rod 6, which is used to drive the bearing plate 7 to perform vertical lifting and lowering movements; two elastic telescopic rods 8 are fixedly inserted through the top two sides of the bearing plate 7, and the circumferential surfaces of the two elastic telescopic rods 8 respectively fit against the inner walls of the two guide holes; pressure plate 9 is fixedly installed at the telescopic end of the elastic telescopic rod 8, which is used to press down and fix the guide rail bracket. By using the pressure plate 9 to stably press a group of guide rail brackets, the deburring process of the end faces of four guide rail brackets can be completed at one time, which greatly shortens the deburring process time of a single guide rail bracket.

[0022] The top of the sliding platform 4 is equipped with two sets of clamping mechanisms. The clamping mechanisms include a fixed seat 10, a screw 11, a knob 12, and a positioning plate 13. The fixed seat 10 is fixedly installed on the top of the sliding platform 4. The surface of the fixed seat 10 has an internal threaded through hole that matches the screw 11. The screw 11 is threaded into the internal threaded through hole. The knob 12 is fixedly installed on one end of the screw 11. The positioning plate 13 is rotatably installed on the other end of the screw 11. The bottom of the positioning plate 13 is in contact with the top of the sliding platform 4. The positioning plates 13 on both sides achieve double-sided limiting and lateral clamping of the guide rail bracket, effectively eliminating gaps and realizing one-time synchronous positioning of multiple C-shaped steel structure guide rail brackets.

[0023] Two sets of grinding wheel polishing devices 2 are symmetrically arranged on the top two sides of the processing table 1, and two sets of clamping mechanisms are symmetrically arranged on the top two sides of the sliding platform 4. Through the flexible use of the positioning plates 13 on both sides, the positioning constraints can be quickly released after the deburring process is completed, making it convenient for operators to pick up and put down the guide rail bracket.

[0024] A protective cover is fixedly installed on the surface of the grinding wheel polishing device 2. The protective cover is used to block the splashing of metal shavings generated during the deburring process, and the safety of the operator is ensured by installing the protective cover.

[0025] In this embodiment, when deburring the end face of C-shaped steel elevator guide rail brackets of uniform specifications, the operator is located on the left side of the processing table 1. Four guide rail brackets are placed as a group, and the group of guide rail brackets is aligned and placed on the top of the sliding platform 4. The outer wall of the right guide rail bracket is made to fit with the right positioning plate 13 to complete the initial positioning. Then, the left knob 12 is manually rotated. The knob 12 drives the screw 11 to rotate synchronously along the internal thread through hole of the fixed seat 10, driving the left positioning plate 13 to move to the right. During the translation, the left positioning plate 13 gradually fits with the outer wall of the left guide rail bracket and continuously applies a pushing force to make the group of four guide rail brackets fit together, eliminate gaps, and achieve rapid positioning of a group of guide rail brackets. The two side positioning plates 13 realize double-sided limiting and lateral clamping of the guide rail brackets, effectively eliminating gaps and realizing one-time synchronous positioning of multiple C-shaped steel elevator guide rail brackets, improving the processing efficiency of batch deburring operations. After positioning is completed, the electric push rod 6 is activated. The output end of the electric push rod 6 drives the bearing plate 7 to descend smoothly to the set position. The bearing plate 7 drives the elastic telescopic rod 8 to move down synchronously along the guide hole. The elastic telescopic rod 8 drives the pressure plate 9 to move downward, so that the pressure plate 9 contacts the top of the guide rail bracket. As the bearing plate 7 continues to move down, the telescopic end of the elastic telescopic rod 8 is squeezed, generating an elastic reaction, so that the pressure plate 9 applies a stable downward pressure to the top of the guide rail bracket, firmly pressing the guide rail bracket onto the top of the sliding platform 4. Then, the grinding wheel polishing device 2 and the drive module 3 are activated simultaneously. The linear drive device drives the sliding platform 4 to move smoothly to the right along the optical axis guide rail. The symmetrically arranged grinding wheel polishing devices In position 2, two high-speed rotating grinding wheels synchronously contact the end faces of the guide rail brackets, achieving synchronous deburring of the end faces. During the deburring process, the pressure plate 9 and the positioning plate 13 cooperate with each other to reliably press and limit the guide rail brackets, effectively preventing the guide rail brackets from shaking or shifting, and ensuring stable contact between the end faces of the guide rail brackets and the grinding wheels. When the sliding platform 4 moves to the right end point, the deburring operation of the end faces of a set of four guide rail brackets is completed. By using the pressure plate 9 to stably press a set of guide rail brackets, and in conjunction with the positioning plate 13, the deburring of the end faces of four guide rail brackets can be completed at one time, greatly shortening the deburring time of a single guide rail bracket. After the sliding platform 4 moves to the right end point and completes the deburring of a set of guide rail brackets, the output end of the electric push rod 6 drives the bearing plate 7 to reset upward. The bearing plate 7 drives the elastic telescopic rod 8 to move upward synchronously, so that the compressed telescopic end of the elastic telescopic rod 8 gradually rebounds and resets until the pressure plate 9 completely disengages from the top of the guide rail bracket. Then, the operator rotates the right knob 12 on the right side of the processing table 1 to drive the right positioning plate 13 to move horizontally to the right, so that the right positioning plate 13 separates from the outer wall of the guide rail bracket. The operator then takes out the processed guide rail brackets one by one, thus completing the entire deburring process of a set of guide rail brackets. Through the flexible use of the two side positioning plates 13, the positioning constraint can be quickly released after the deburring process is completed, which makes it convenient for the operator to pick up and put down the guide rail brackets, improving the overall efficiency of clamping, positioning and unloading.

[0026] Please see Figure 1 - Figure 9 Based on the above embodiments, in another embodiment of the present invention, the top of the processing table 1 is provided with a calibration device for automatically calibrating the end face of the guide rail bracket, and the calibration device is provided with a limit protection device for improving the standardization of operation; the calibration device includes a mounting frame 21, a guide rod 22, a clamping plate 23, an arc block 24, a straight rod 25, a sleeve 26, a linkage plate 27, a rectangular plate 28, and rollers 29. The mounting frame 21 is fixedly installed on the top of the processing table 1, the guide rod 22 slides through the surface of the mounting frame 21, and the clamping plate 23 is fixedly installed near the guide rod 22. At one end of the electric push rod 6, the arc block 24 is fixedly installed on the side of the clamping plate 23 near the mounting frame 21, the straight rod 25 is fixedly installed on the surface of the mounting frame 21, the sleeve 26 is slidably installed on the circumferential surface of the straight rod 25, the linkage plate 27 is fixedly installed on the circumferential surface of the sleeve 26, the rectangular plate 28 is fixedly installed on the circumferential surface of the sleeve 26, the inner wall of the rectangular plate 28 is rotatably penetrated by a rotating shaft, and the roller 29 is fixedly installed on the circumferential surface of the rotating shaft. By linking the bearing plate 7 to drive the clamping plates 23 on both sides to move in the same direction, the alignment and calibration of the end faces of a set of guide rail brackets can be completed at one time.

[0027] A first spring is provided between the guide rod 22 and the mounting frame 21, and a second spring is provided between the sleeve 26 and the mounting frame 21. A rectangular limiting groove is provided on the top of the rectangular plate 28. Through the automatic reset of the first spring, the clamping plate 23 can be quickly retracted after calibration, providing safe clearance space for the movement of the guide rail bracket.

[0028] The limit protection device includes a fixed plate 31, a limit plate 32, a circular plate 33, a reset spring 34, a T-shaped plate 35, and a triangular block 36. The fixed plate 31 is fixedly installed on the side of the mounting frame 21 away from the straight rod 25. The limit plate 32 is slidably installed on the inner wall of the fixed plate 31 and slides through the surface of the mounting frame 21. The circular plate 33 is fixedly installed on the side of the limit plate 32 away from the straight rod 25. The reset spring 34 is disposed between the fixed plate 31 and the circular plate 33. The T-shaped plate 35 is fixedly installed on the surface of the circular plate 33. The triangular block 36 is fixedly installed at the bottom of the rectangular plate 28. The side of the limit plate 32 away from the circular plate 33 has an arc surface. The limit plate 32 automatically blocks and limits the rectangular plate 28 that has moved down to its position, ensuring that when the sliding platform 4 moves the guide rail bracket to the right for deburring, the clamping plate 23 remains in a avoidance state.

[0029] A circular tube 37 is fixedly installed on the side of the fixed plate 31 near the circular plate 33. A damping ring is provided on the circumferential surface of the circular plate 33. The damping ring is in contact with the inner wall of the circular tube 37. Through the frictional resistance between the damping ring and the inner wall of the circular tube 37, combined with the elastic resistance of the reset spring 34, the limit plate 32 is ensured to move under standardized and controllable manual operation.

[0030] In this embodiment, during operation: as the output end of the electric push rod 6 drives the bearing plate 7 to move downward, the bottom of the bearing plate 7 contacts the top of the linkage plate 27, thereby causing the linkage plate 27 to move downward synchronously. The linkage plate 27 drives the sleeve 26 to slide downward along the straight rod 25. The sleeve 26 pulls down the second spring to cause it to undergo elastic deformation. At the same time, the sleeve 26 drives the rectangular plate 28 to move downward, and the rectangular plate 28 drives the roller 29 to move downward synchronously. During the downward movement, the roller 29 contacts the arc surface of the arc block 24. As the roller 29 continues to move downward, it generates a thrust on the arc surface of the arc block 24. This thrust drives the arc block 24 and the clamping plate 23 to move downward. The clamping plate 23 moves horizontally away from the straight rod 25, causing the guide rod 22 to move synchronously. This causes the guide rod 22 to compress the first spring and cause it to undergo elastic deformation. At the same time, the translating clamping plate 23 contacts the end face of the guide rail bracket and applies a stable thrust. In conjunction with the clamping plate 23 on the other side moving synchronously, the end faces of both ends of the guide rail bracket are automatically aligned and calibrated, ensuring that the end faces of a set of guide rail brackets are flush and uniform. By driving the clamping plates 23 on both sides to move in the same direction through the linkage of the bearing plate 7, the alignment and calibration of the end faces of a set of guide rail brackets can be completed in one go, effectively avoiding the problem of uneven deburring caused by uneven end faces. As the roller 29 continues to move downward and gradually disengages from the arc block 24, its thrust on the arc block 24 gradually decreases. At this time, the first spring, which is in a state of compression deformation, begins to elastically reset. The rebound of the first spring drives the guide rod 22 and the clamping plate 23 to reset to their initial positions, so that the clamping plate 23 quickly disengages after the end face calibration is completed. This ensures that when the sliding platform 4 drives the guide rail bracket to move to the right for deburring, the end face of the guide rail bracket will not interfere with the clamping plate 23, ensuring the smooth transport of the guide rail bracket. Through the automatic reset of the first spring, the clamping plate 23 can quickly retract after calibration, providing a safe clearance space for the movement of the guide rail bracket, avoiding friction between the end face of the guide rail bracket and the clamping plate 23, and ensuring the quality of the end face processing. When the sleeve 26 moves the rectangular plate 28 downward, the rectangular plate 28 moves the triangular block 36 downward synchronously. During the downward movement, the inclined surface of the triangular block 36 first contacts the arc surface of the limiting plate 32 and generates a horizontal thrust on the limiting plate 32. This thrust drives the limiting plate 32 to translate away from the straight rod 25. The limiting plate 32 moves the circular plate 33 and the T-shaped plate 35 synchronously. During the movement, the circular plate 33 stretches the reset spring 34, causing it to undergo elastic deformation. When the triangular block 36 moves to the preset position and disengages from the limiting plate 32, the reset spring 34 elastically returns to its original position. The circular plate 33 is driven to quickly reset, and the circular plate 33 then drives the limiting plate 32 and the T-shaped plate 35 to reset synchronously. After the reset, the limiting plate 32 fits with the rectangular limiting groove on the rectangular plate 28, forming a blocking constraint on the upward movement of the rectangular plate 28. At this time, the top of the bearing plate 7 and the linkage plate 27 are disengaged. Under the limiting action of the limiting plate 32, the rectangular plate 28 remains stationary. The limiting plate 32 automatically blocks and limits the rectangular plate 28 that has moved down to the position, ensuring that when the sliding platform 4 drives the guide rail bracket to move to the right for deburring, the clamping plate 23 remains in an avoidance state. After the operator completes the unloading on the right side of the processing table 1, the linear drive device drives the sliding platform 4 to slide to the left along the optical axis guide rail to reset. When the sliding platform 4 returns to the initial position, the operator pulls the T-shaped plate 35 away from the fixed plate 31. The T-shaped plate 35 drives the circular plate 33 and the limiting plate 32 to move synchronously. The operator manually releases the limiting plate 32 from the rectangular plate 28. After the limiting is released, the second spring, which is in a deformed state, elastically resets and drives the sleeve 26 to reset upward along the straight rod 25. During this process, the circular plate 33 moves inside the circular tube 37. The damping ring on its circumference forms frictional damping with the inner wall of the circular tube 37, so that the operator needs to apply a stable pulling force when pulling the T-shaped plate 35 to avoid misoperation. Through the frictional resistance between the damping ring and the inner wall of the circular tube 37, combined with the elastic resistance of the reset spring 34, the operator ensures that the limiting plate 32 is displaced under standardized and controllable manual operation, effectively improving the safety of operation.

10. A method for operating an elevator guide rail bracket end face deburring device, using the elevator guide rail bracket end face deburring device as described in claim 9, characterized in that... Includes the following steps: Step 1: Place a set of four guide rail brackets on the top of the sliding platform (4), then manually rotate the left knob (12) to drive the left positioning plate (13) to fit against the outer wall of the left guide rail bracket, and continuously apply the thrust to make the four guide rail brackets fit against each other, eliminate gaps, and achieve rapid positioning of a set of guide rail brackets. Step 2: Start the electric push rod (6). The output end of the electric push rod (6) drives the bearing plate (7) to descend to the set position. The bearing plate (7) drives the elastic telescopic rod (8) to move down. The elastic telescopic rod (8) drives the pressure plate (9) to move down. The pressure plate (9) contacts the top of the guide rail bracket and applies a stable downward pressure to firmly press the guide rail bracket onto the top of the sliding platform (4). Step 3: Simultaneously start the grinding wheel polishing device (2) and the drive module (3). The linear drive device drives the sliding platform (4) to move to the right along the optical axis guide rail. In the symmetrically arranged grinding wheel polishing device (2), the two high-speed rotating grinding wheels contact the end faces of the guide rail bracket at the same time, so as to realize the simultaneous deburring of the end faces at both ends. Step 4: After deburring a set of guide rail brackets, the output end of the electric push rod (6) drives the bearing plate (7) to reset upwards until the pressure plate (9) is completely disengaged from the top of the guide rail bracket. The operator then takes out the processed guide rail brackets in sequence, thus completing the deburring process of a set of guide rail brackets.
