Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to polishing equipment for tool processing. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It is a finishing process that uses polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece. Polishing is required in the tool manufacturing process, so polishing equipment for tool processing is needed.

[0003] According to the patent application CN 217776631U, a polishing device for CNC tool processing is described as follows: "This utility model provides a polishing device for CNC tool processing, including an operating table, a top plate above the operating table, the top plate and the operating table connected by a lifting device, a movable seat below the top plate, a polisher at the bottom of the movable seat, two rectangular holes in the top plate, two movable seats passing through the two rectangular holes respectively, two support plates fixedly connected to the top of the top plate, the two support plates connected by a connecting column, a bidirectional lead screw above the top plate, and push plates on the opposite sides of the two movable seats, the push plates and movable seats connected by elastic elements. This CNC tool processing polishing device belongs to the field of tool manufacturing machinery technology. By changing the deformation of the compression spring, the pressure of the polisher on the tool can be adjusted. After adjustment, a locking mechanism limits the position of the bidirectional lead screw, preventing rotation of the bidirectional lead screw due to non-human factors, thus improving stability."

[0004] Regarding the above description, the applicant believes the following issues exist: The tool is placed between the two clamping plates. The second one-way screw is rotated, causing it to move along the second fixed plate and clamp the tool. The two adjacent nuts are then tightened to secure the second one-way screw. The second fixed plate is lifted, causing the insert rod to disengage from the slot, stretching the spring and releasing the limiting effect on the first fixed plate. The first fixed plate is rotated, driving the bidirectional screw to rotate, causing the two movable seats to bring the polisher closer to the tool. Adjusting the bidirectional screw changes the distance between the push plate and the movable seats, thereby adjusting the pressure applied by the polisher. After adjustment, the second fixed plate is released, allowing it to reset and fix the first fixed plate, limiting the bidirectional screw. Finally, the polisher position is adjusted by the motor and the polishing disc is started for polishing. In actual operation, this device has obvious efficiency and safety hazards. Its operation process requires frequent manual disassembly and installation of the tool to complete the grinding process: the operator needs to manually loosen the clamp to remove the tool, and after grinding, put it back and adjust its position. This process needs to be repeated, which is not only time-consuming and labor-intensive, resulting in low overall processing efficiency and difficulty in meeting the needs of large-scale production; but also poses a risk of safety accidents due to operational errors or equipment failures during the disassembly, installation and adjustment of the tool.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5This utility model provides an embodiment of a polishing device for tool processing, including a base plate 1; it also includes a mounting bracket 21 and a polishing assembly. A support leg 6 is fixedly connected to the bottom of the base plate 1, a side plate 7 is fixedly connected to the top of the base plate 1, a control device 5 is fixedly connected to the outside of the side plate 7, a top plate 4 is fixedly connected to the back of the base plate 1, the mounting bracket 21 is fixedly connected to the top of the base plate 1, the polishing assembly is disposed at the bottom of the top plate 4, and a connecting bracket 22 is fixedly connected to the outside of the mounting bracket 21. A motor 23 is provided, and a rotating plate 24 is fixedly connected to the output end of the motor 23. The motor 23 drives the rotating plate 24 to rotate. An intermittent plate 25 is rotatably connected inside the mounting bracket 21. A sprocket 26 is fixedly connected to the outside of the intermittent plate 25. A chain 27 is driven by the outside of the sprocket 26. A sprocket 28 is driven by the end of the chain 27 away from the sprocket 26. A fixing component is provided on the outside of the chain 27. The rotating plate 24 is driven to rotate by the motor 23, so that the rotating plate 24 approaches and enters the intermittent plate 25. The internal rotation then occurs, moving out from the interior of the intermittent plate 25, causing the rotating plate 24 to drive the intermittent plate 25 to rotate intermittently. At this time, the intermittent plate 25 drives the chain 27 outside the first sprocket 26 to rotate outside the second sprocket 28. Since the chain 27 pauses during its movement, the tool to be sharpened can be placed inside the fixing assembly for fixation, and the sharpened tool can be removed from the fixing assembly. The fixing assembly includes a fixing frame 29, which is fixedly connected to the outside of the chain 27. The internal fixed connection of the fixed frame 29 is a motor 210. The output end of the motor 210 is fixedly connected to a screw 211. The external thread of the screw 211 is connected to a sliding plate 212. The inner side of the fixed frame 29 is fixedly connected to a sliding rod 216. The external rotatable connection of the fixed frame 29 is an L-shaped rotating plate 213. The internal sliding connection of the L-shaped rotating plate 213 is a clamping block 214. The external fixed connection of the clamping block 214 is a protective plate 215. The clamping block 214 facilitates the pushing of the protective plate 215 to fix the tool.

[0022] Please see Figure 2-4In this embodiment, the intermittent plate 25 has evenly distributed sliding grooves. The rotating plate 24 is movably connected to the inside of the intermittent plate 25 through the sliding grooves. Due to the intermittent plate 25, it is beneficial to drive the chain 27 outside the sprocket 26 to rotate intermittently outside the sprocket 28. The sliding plate 212 has a through hole. The sliding plate 212 is slidably connected to the outside of the slide rod 216 through the through hole. Due to the sliding plate 212, it is beneficial to drive the L-shaped rotating plate 213 to rotate outside the fixed frame 29. The fixed frame 29 has a second sliding groove. The clamping block 214 is slidably connected through the second sliding groove. Inside the fixed frame 29, the L-shaped rotating plate 213 has a sliding groove 3. The L-shaped rotating plate 213 is movably connected to the outside of the sliding plate 212 through the sliding groove 3. The L-shaped rotating plate 213 facilitates the sliding of the clamping blocks 214 inside the fixed frame 29. When the sliding plate 212 is close to the motor 210, the L-shaped rotating plate 213 makes the two sets of clamping blocks 214 move closer to each other. When the sliding plate 212 is away from the motor 210, the L-shaped rotating plate 213 makes the two sets of clamping blocks 214 move away from each other. Since it is an array motor 210, it is beneficial to provide power for the rotation of the screw 211.

[0023] Please see Figure 5 In this embodiment, the polishing assembly includes a motor 31, which is fixedly connected to the bottom of the top plate 4. A threaded rod 32 is fixedly connected to the output end of the motor 31. A support plate 36 is fixedly connected to the bottom and top of the side plate 7. A sliding rod 34 is fixedly connected to the top of the support plate 36. A polishing device 2 35 is fixedly connected to the top of the support plate 36. A polishing device 1 33 is threadedly connected to the outside of the threaded rod 32. The presence of the polishing device 1 33 facilitates the polishing of the tool in conjunction with the polishing device 2 35.

[0024] During operation, motor 23 drives the rotating plate 24 to rotate, causing it to approach and enter the interior of the intermittent plate 25, where it then rotates and moves out, causing the rotating plate 24 to drive the intermittent plate 25 to rotate intermittently. At this time, the intermittent plate 25 drives the chain 27 outside the sprocket 26 to rotate outside the sprocket 28. Because the chain 27 pauses during its movement, the tool to be sharpened is placed inside the protective plate 215 by a manual operator. Motor 210 drives the screw 211 to rotate, causing the screw 211 to drive the sliding plate 212 to slide outside the slide rod 216. 12 slowly approaches motor 210, causing the L-shaped rotating plate 213 to rotate outside the fixed frame 29. The L-shaped rotating plate 213 drives the clamping block 214 to slide inside the fixed frame 29, thereby fixing the tool. At the same time, the worker on the other side removes the polished tool. With the movement of chain 27, the fixed tool slowly moves out from between polishing device 1 33 and polishing device 2 35. Motor 31 drives polishing device 1 33 to slide outside the sliding rod 34, thereby adjusting according to the thickness of the tool. Through the cooperation of polishing device 1 33 and polishing device 2 35, the tool is polished.

[0025] Through the above steps, motor 23 drives the rotating plate 24 to rotate, causing it to enter the intermittent plate 25 and rotate, before exiting. This action causes the intermittent plate 25 to rotate intermittently, driving the chain 27 on sprocket 26 to move on sprocket 28. During the movement of chain 27, there are pauses or gaps, at which time the worker manually places the tool to be polished inside the protective plate 215. Motor 210 drives the screw 211 to rotate, causing the sliding plate 212 to slide along the sliding rod 216, causing the L-shaped rotating plate 213 to rotate around the fixed frame 29, pushing the clamping block 214 to clamp the tool. Simultaneously, the worker on the other side removes the polished tool, forming a continuous production process, improving production efficiency and ensuring operational safety.
