Description

Technical Field

[0001] The utility model relates to the technical field of tool grinding devices, in particular to a grinding device for tool processing. Background Art

[0002] A tool is a tool used to cut, cut or process materials. It is usually made of metal or other hard materials and has a sharp cutting edge or cutting edge. The tool needs to meet specific geometric shape and size requirements during the processing to ensure that the processed workpiece meets the design requirements. The tool can be adjusted and corrected in geometry through a grinding device to meet processing requirements, so a grinding device for tool processing is needed.

[0003] When an existing tool processing grinding device is in use, the upper electric push rod and the lower electric push rod push the upper clamping plate and the lower clamping plate to move, and the tool is clamped by the upper clamping plate and the lower clamping plate, and the user can use the main electric push rod to push the push plate and the clamped tool to move and adjust the position of the tool.

[0004] However, when using this method, the tool cannot be driven to rotate after clamping. If the tool cannot rotate, the grinding device cannot effectively grind and trim the tool, which will cause uneven wear on the tool surface and geometric shape imbalance, thereby affecting the processing quality and product precision. If the tool is fixed in the grinding device but cannot rotate, it will cause local overheating on the tool surface and even damage the tool. Overheating will cause the tool hardness to decrease, deformation or cracks, seriously affecting the service life of the tool. Utility Model Content

[0028] Place the tool to be processed on the upper part of the workbench 1 to ensure that the tool is placed in the correct position. Then, start the motor 2, whose output end is closely connected with the threaded rod 3. When the motor 2 is started, the threaded rod 3 begins to rotate. The rotation of the threaded rod 3 drives the threaded sleeve 4 to move along the rod body. The movement of the threaded sleeve 4 further drives the movement of the hinge block 5. The hinge block 5 is closely connected with the adjusting rod 6. This structural design makes the movement more stable and accurate. With the movement of the hinge block 5, the hinge block 2 7 connected through the adjusting rod 6 also begins to move. The movement of the hinge block 2 7 further drives the movement. The plate 8 slides on the outside of the guide rod 9, and this sliding is smooth and stable, ensuring that the clamping process of the tool is both stable and reliable. As the movable plate 8 moves, the motor 2 11 and the clamping piece 12 gradually approach to clamp the tool. When the two clamping pieces 12 firmly clamp the tool, start the motor 2 11. The output end of the motor 2 11 is connected to the clamping piece 12. When the motor 2 11 is started, the clamping piece 12 starts to rotate, and the clamping piece 12 drives the support rod 15 to rotate, and then drives the slider 16 to rotate inside the slide rail 17. Under the action of the slider 16, the two clamping pieces 12 drive the tool to rotate.

[0029] Reference Figure 1 , Figure 4 and Figure 5A fixing frame 18 is fixedly connected to the upper part of the workbench 1, and hydraulic cylinders 22 are fixedly connected to both sides of the upper part of the fixing frame 18. The output ends of the two hydraulic cylinders 22 are fixedly connected to protective covers 23, and both sides of the protective covers 23 are fixedly connected to limit plates 24. Limit rods 25 are fixedly connected to both sides of the bottom of the fixing frame 18. The two limit plates 24 are slidably connected to the outside of the limit rods 25. A spring 26 is sleeved on the outside of the limit rods 25, one end of the spring 26 is fixedly connected to the bottom of the fixing frame 18, and the other end of the spring 26 is fixedly connected to the upper part of the limit plate 24. A placing table 19 is fixedly connected to the upper part of the placing table 19, and a cylinder 20 is fixedly connected to the upper part of the placing table 19. A grinding mechanism 21 is fixedly connected to the output end of the cylinder 20. The protective cover 23 is arranged on the upper part of the clamping member 12, and a grinding mechanism 21 is arranged inside the protective cover 23.

[0030] When the operator starts the hydraulic cylinder 22, its output end will quickly push the protective cover 23 downward. The protective cover 23 is not only sturdy and durable, but also has excellent sealing performance. The movement of the protective cover 23 is precisely controlled by the limit plate 24 and the limit rod 25. The limit plate 24 is slidably connected to the outside of the limit rod 25. As the protective cover 23 moves, it will slide on the limit rod 25 to squeeze or stretch the spring 26. The spring 26 can not only provide necessary buffering, but also ensure the stable movement of the protective cover 23. Under the guidance of the limit plate 24, the protective cover 23 is accurately moved to the outside of the tool to form a complete protective barrier. The output end of the cylinder 20 pushes the grinding mechanism 21 downward to ensure that the grinding mechanism 21 can contact the tool. When the grinding mechanism 21 contacts the tool, the grinding mechanism 21 is started for grinding.

[0031] Working principle: first, place the tool to be processed on the upper part of the workbench 1, start the motor 2, the output end of the motor 2 drives the threaded rod 3 to rotate, the rotation of the threaded rod 3 drives the threaded sleeve 4 to move, the movement of the threaded sleeve 4 drives the hinge block 5 to move, the movement of the hinge block 5 drives the hinge block 2 7 connected by the adjusting rod 6 to move, the movement of the hinge block 2 7 drives the moving plate 8 to slide on the outside of the guide rod 9, the movement of the moving plate 8 drives the motor 2 11 and the clamping piece 12 to get close until the two clamping pieces 12 clamp the tool, then start the motor 2 11, the output end of the motor 2 11 drives the clamping piece 12 to rotate, the rotation of the clamping piece 12 drives the support rod 15 to rotate, the rotation of the support rod 15 drives the slider 16 to rotate inside the slide rail 17, under the action of the slider 16, the two clamping pieces 12 drive the tool to rotate, thereby realizing that the tool can be effectively driven to rotate after clamping. , ensuring that the tool is ground evenly during the grinding process, avoiding local overheating or excessive wear, ensuring the accuracy and consistency of the processing process, and improving the quality of the product and processing efficiency. When the tool needs to be ground, start the cylinder 20, and the output end of the cylinder 20 pushes the grinding mechanism 21 to move downward. When the grinding mechanism 21 contacts the tool, start the grinding mechanism 21 to grind the tool, and at the same time start the hydraulic cylinder 22. The output end of the hydraulic cylinder 22 pushes the protective cover 23 to move downward. When the protective cover 23 moves, it drives the limit plate 24 to slide outside the limit rod 25. When the limit plate 24 moves, it squeezes or stretches the spring 26. Under the action of the limit plate 24, the protective cover 23 moves downward and moves to the outside of the tool, thereby effectively preventing the debris, dust or spatter generated during the tool grinding process from splashing out, reducing the risk of injury to the operator and improving work safety.
