Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, specifically to a grinding machine for cutting tool processing. Background Technology

[0002] A cutting tool is a cutting tool used for cutting and is widely used in machining, including turning, boring, planing and other machining methods; a grinding machine is a machine tool that uses abrasive tools (such as grinding wheels, oilstones, abrasive belts, etc.) to grind the surface of a workpiece. Its main function is to achieve high surface quality and dimensional accuracy of the workpiece, and it is widely used in precision parts manufacturing and tool grinding.

[0003] Patent No. 201320378835.1 discloses a grinding machine for processing slicing cutters. This device moves the worktable through the meshing of gears and racks, thereby processing the cutters. The meshing transmission speed between the gears and racks is uniform and stable, resulting in high precision of the processed cutters. This ensures the straightness of the processed cutters and also improves the production efficiency of the cutters.

[0004] However, existing grinding machines used for processing slicing cutters rely on screws, fasteners, and bushings to secure the cutter. After processing one side of the cutter, workers must manually disassemble these components to flip the cutter over before securing it again. This process is cumbersome, and the cutting process also generates debris that needs to be manually cleaned, impacting the processing efficiency. Therefore, a new grinding machine for processing cutters is needed. Utility Model Content

[0005] The main objective of this invention is to provide a grinding machine for processing cutting blades. This invention, through the arrangement of drive rod A, drive rod B, cam, support rod, pressure roller, spring, fixing plate, brush, transmission plate, and processing frame, solves the problems of existing grinding machines used for processing slicing machine cutting blades, which make it inconvenient to flip the cutting blades during use and to clean the processing debris on the cutting blades.

[0006] The technical solution adopted by this utility model to solve its technical problem is a grinding machine for cutting blade processing, including a base and a movable frame. A fixed frame is welded to one side of the base, and a drive frame is slidably connected to the outside of the fixed frame. A bracket is slidably connected to the inside of the drive frame, and a servo motor A that provides power is bolted to the outside of the bracket. A grinding wheel for processing the cutting blade is keyed to the power output end of the servo motor A. A servo motor C that provides power is bolted to the outside of the movable frame, and a drive rod B is keyed to the power output end of the servo motor C. A processing frame for placing the cutting blade is welded to the end of the drive rod B away from the servo motor C. A drive rod A is welded to the end of the frame away from the servo motor C. Both drive rod A and drive rod B are fitted with cams. An electric telescopic rod that provides power is symmetrically screwed inside the processing frame. A limiting plate that limits the cutting tool to be processed is screwed to one side of the electric telescopic rod. A transmission plate is slidably connected to one side of the moving frame. A brush for cleaning the cutting tool is screwed to the inside of the transmission plate. A support rod is symmetrically screwed to one side of the transmission plate. A pressure roller that contacts the cam is rotatably connected to the end of the support rod. A fixed plate is symmetrically welded to the end of the transmission plate. Springs that connect to the fixed plate are symmetrically welded inside the moving frame.

[0007] By adopting the above technical solution, when processing the cutting blade structure, the cutting blade is first placed in the processing frame. Then, the electric telescopic rods symmetrically installed in the processing frame are driven by the external controller to move the limiting plates, so that the two sets of limiting plates clamp the cutting blade. Then, the cutting blade is processed by the grinding wheel. After one side of the cutting blade is processed, the servo motor C outside the moving frame is driven by the external control to drive the drive rod B to rotate. Then, the drive rod B drives the processing frame at the end to move. At the same time, the processing frame drives the drive rod A on one side to rotate, rotating the processing frame and causing the cutting blade in the processing frame to flip over, thereby improving the processing efficiency of the cutting blade.

[0008] When the processing frame drives the inner cutter to rotate, the cams welded to the outside of drive rods A and B move outside the pressure roller. As the protruding part of the cam separates from the pressure roller, the support rod on one side of the pressure roller is relieved of pressure. The spring in the moving frame is initially in a compressed state. When the support rod is relieved of pressure, the spring drives the fixed plate to return to its original position. Then the fixed plate drives the transmission plate on one side to move. The transmission plate moves towards the cutting surface of the cutter. When the processing frame rotates to 90 degrees, the cutter in the processing frame is in a vertical state. At this time, the pressure roller on the support rod is completely separated from the protruding part on the cam, so that the brush in the transmission plate contacts the cutter. The cam has symmetrical protrusions on both sides. As the moving frame rotates, the pressure roller on the support rod contacts the protrusion on the other side of the cam. Then the support rod drives the transmission plate to move. The transmission plate drives the fixed plate to compress the spring in the moving frame. When the processing frame rotates to 180 degrees, the cutter in the processing frame is flipped. At this time, the transmission plate moves to the initial position, which facilitates the cleaning of the debris processed on the cutter.

[0009] Specifically, a cylinder that drives the drive frame to move longitudinally is bolted to one side of the fixed frame, and an electric push rod that drives the bracket to move is fixed inside the drive frame with screws.

[0010] By adopting the above technical solution, when the cutter in the processing frame is to be processed, the cylinder outside the fixed frame is driven by the external controller to move the drive frame connected to the bolt at the end, so that the drive frame drives the grinding wheel in the bracket to contact the cutter. At the same time, the electric push rod in the drive frame is driven by the external controller to move the bracket fixed to one side by screws, so that the bracket drives the grinding wheel to move, thereby adjusting the position of the grinding wheel and improving the processing efficiency of the cutter.

[0011] Specifically, the base is bolted to a servo motor B that provides power, and the power output end of the servo motor B is keyed to a lead screw.

[0012] By adopting the above technical solution, when the lead screw needs to be rotated, the servo motor B in the base converts the received electrical energy into mechanical energy under the action of the external controller, and the servo motor B drives the lead screw to rotate.

[0013] Both the end of the lead screw away from the servo motor B and the end of the drive rod A that contacts the moving frame are fitted with bearings with an interference fit, which makes the lead screw and drive rod A rotate stably.

[0014] Specifically, the lead screw is externally threaded with a support sleeve, and a support plate is welded to the outside of the support sleeve to drive the moving frame to move laterally.

[0015] By adopting the above technical solution, when the lead screw rotates, the support sleeve outside the lead screw is limited by the external symmetrical structure to move laterally outside the lead screw. Then, the support plate welded to the outside of the support sleeve drives the moving frame welded to the top to move, thereby facilitating the adjustment of the position of the cutter inside the moving frame.

[0016] Specifically, the fixed plate is symmetrically welded with sliders on the outside, and the movable frame is symmetrically provided with grooves on the inside to allow the sliders to slide.

[0017] By adopting the above technical solution, when the fixed plate moves within the moving frame, the sliders symmetrically welded to the outside of the fixed plate slide within the symmetrically opened grooves inside the moving frame, thereby improving the stability of the fixed plate's movement.

[0018] The beneficial effects of this utility model are:

[0019] (1) The grinding machine for cutting tool processing described in this utility model, when the cutting tool structure is to be processed, firstly, the cutting tool is placed in the processing frame, and then the electric telescopic rods symmetrically installed in the processing frame are driven by the external controller to move the limiting plate, so that the two sets of limiting plates clamp the cutting tool. Then, the cutting tool is processed by the grinding wheel. After the cutting tool is processed on one side, the servo motor C outside the moving frame is driven by the external control to drive the drive rod B to rotate. Then, the drive rod B drives the processing frame at the end to move, and at the same time, the processing frame drives the drive rod A on one side to rotate, so that the cutting tool in the processing frame is flipped, thereby improving the processing efficiency of the cutting tool.

[0020] (2) In the grinding machine for cutting tool processing described in this utility model, when the processing frame drives the inner cutting tool to rotate, the cams welded to the outside of the drive rods A and B move outside the pressure roller. As the protruding part of the cam separates from the pressure roller, the support rod on one side of the pressure roller releases the pressure, and the spring in the moving frame is initially in a compressed state. When the support rod releases the pressure, the spring drives the fixed plate to reset, and then the fixed plate drives the transmission plate on one side to move. The transmission plate moves towards the cutting tool processing surface. When the processing frame rotates to 90 degrees, the cutting tool in the processing frame is in a vertical state. At this time, the pressure roller on the support rod is completely separated from the protruding part on the cam, so that the brush in the transmission plate contacts the cutting tool. The cam has symmetrically arranged protruding parts on both sides. As the moving frame rotates, the pressure roller on the support rod contacts the protrusion on the other side of the cam. Then the support rod drives the transmission plate to move, and the transmission plate drives the fixed plate to compress the spring in the moving frame. When the processing frame rotates to 180 degrees, the cutting tool in the processing frame is flipped. At this time, the transmission plate moves to the initial position, which facilitates the cleaning of the debris processed on the cutting tool. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To improve the processing efficiency of the cutting tool, as one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a grinding machine for machining cutting tools, comprising a base 23 and a movable frame 18. A fixed frame 2 is welded to one side of the base 23, and a drive frame 3 is slidably connected to the outside of the fixed frame 2. A bracket 16 is slidably connected to the inside of the drive frame 3, and a servo motor A4 for providing power is bolted to the outside of the bracket 16. A grinding wheel 5 for machining cutting tools is keyed to the power output end of the servo motor A4. A servo motor C21 for providing power is bolted to the outside of the movable frame 18, and a drive rod B20 is keyed to the power output end of the servo motor C21. A machining frame 17 for placing cutting tools is welded to the end of the drive rod B20 away from the servo motor C21. The machining frame 17 is away from the servo motor. A drive rod A6 is welded to one end of C21. Both drive rod A6 and drive rod B20 are fitted with cams 19. An electric telescopic rod 9 providing power is symmetrically screwed inside the processing frame 17. A limiting plate 7 for limiting the cutting blade to be processed is screwed to one side of the electric telescopic rod 9. A transmission plate 8 is slidably connected to one side of the moving frame 18. A brush 24 for cleaning the cutting blade is screwed to the inside of the transmission plate 8. A support rod 25 is symmetrically screwed to one side of the transmission plate 8. A pressure roller 22 that contacts the cam 19 is rotatably connected to the end of the support rod 25. A fixed plate 26 is symmetrically welded to the end of the transmission plate 8. A spring 15 connected to the fixed plate 26 is symmetrically welded inside the moving frame 18.

[0028] When using the cutting tool, first place the cutting tool into the processing frame 17. Then, the electric telescopic rods 9, which are symmetrically installed in the processing frame 17, are driven by the external controller to move the limiting plates 7, so that the two sets of limiting plates 7 clamp the cutting tool. Then, the grinding wheel 5 is used to process the cutting tool. After one side of the cutting tool is processed, the servo motor C21 outside the moving frame 18 is driven by the external controller to drive the drive rod B20 to rotate. Then, the drive rod B20 drives the processing frame 17 at the end to move. At the same time, the processing frame 17 drives the drive rod A6 on one side to rotate, rotating the processing frame 17 by a certain degree, so that the cutting tool in the processing frame 17 is flipped, thereby improving the processing efficiency of the cutting tool.

[0029] When the processing frame 17 drives the inner cutter to rotate, the cam 19, which is welded to both drive rod A6 and drive rod B20, moves outside the pressure roller 22. As the protruding part of the cam 19 separates from the pressure roller 22, the support rod 25 on one side of the pressure roller 22 is released from pressure. The spring 15 inside the moving frame 18 is initially in a compressed state. When the support rod 25 is released from pressure, the spring 15 drives the fixed plate 26 to return to its original position. Then, the fixed plate 26 drives the transmission plate 8 on one side to move. The transmission plate 8 moves towards the cutting surface of the cutter. When the processing frame 17 rotates to 90 degrees, the cutter inside the processing frame 17 is in a vertical state. At this time, the support rod 25... The pressure roller 22 is completely separated from the protrusion on the cam 19, so that the brush 24 in the transmission plate 8 contacts the cutter. The cam 19 has symmetrical protrusions on both sides. As the moving frame 18 rotates, the pressure roller 22 on the support rod 25 contacts the protrusion on the other side of the cam 19. Then the support rod 25 drives the transmission plate 8 to move. The transmission plate 8 drives the fixed plate 26 to compress the spring 15 in the moving frame 18. When the processing frame 17 rotates to 180 degrees, the cutter in the processing frame 17 is flipped. At this time, the transmission plate 8 moves to the initial position, which makes it easier to clean the debris processed on the cutter.

[0030] To improve the processing efficiency of the cutting tool, for example, such as Figure 1 As shown, the present invention also includes a cylinder 1 bolted to one side of the fixed frame 2, which drives the drive frame 3 to move longitudinally, and an electric push rod 10 that drives the bracket 16 to move is fixed inside the drive frame 3 by screws.

[0031] When the cutting tool inside the processing frame 17 is to be processed, the cylinder 1 outside the fixed frame 2 is driven by the external controller to move the drive frame 3 bolted to its end. This causes the drive frame 3 to drive the grinding wheel 5 inside the bracket 16 to contact the cutting tool. At the same time, the electric push rod 10 inside the drive frame 3 is driven by the external controller to move the bracket 16 fixed to one side by screws. This causes the bracket 16 to drive the grinding wheel 5 to move, adjusting the position of the grinding wheel 5 and improving the processing efficiency of the cutting tool.

[0032] To drive the lead screw 14 to rotate, for example, as shown in the example... Figure 3As shown, the present invention also includes a servo motor B11 that provides power is bolted inside the base 23, and a lead screw 14 is keyed to the power output end of the servo motor B11.

[0033] When in use, when the lead screw 14 is to be rotated, the servo motor B11 in the base 23 converts the received electrical energy into mechanical energy under the action of the external controller, and the servo motor B11 drives the lead screw 14 to rotate.

[0034] To adjust the position of the cutter within the movable frame 18, for example, such as Figure 3 As shown, the present invention also includes a support sleeve 12 externally threaded to the lead screw 14, and a support plate 13 for driving the movable frame 18 to move laterally is welded to the outside of the support sleeve 12.

[0035] When in use, when the lead screw 14 rotates, the sleeve 12 outside the lead screw 14 is limited by the external symmetrical structure and moves laterally outside the lead screw 14. Then, the support plate 13 welded to the outside of the sleeve 12 drives the movable frame 18 welded to the top to move, thereby facilitating the adjustment of the position of the cutter inside the movable frame 18.

[0036] To improve the stability of the movement of the fixed plate 26, for example, such as Figure 2 As shown, the present invention also includes a slider 28 symmetrically welded to the outside of the fixed plate 26, and a sliding groove 27 symmetrically opened on the inside of the movable frame 18 to allow the slider 28 to slide.

[0037] When the fixed plate 26 moves within the movable frame 18 during use, the sliders 28 symmetrically welded to the outside of the fixed plate 26 slide within the symmetrically opened grooves 27 inside the movable frame 18, thereby improving the stability of the movement of the fixed plate 26.

[0038] In use, when the cutting blade structure needs to be modified, the cutting blade is first placed in the processing frame 17. Then, the electric telescopic rods 9 symmetrically installed in the processing frame 17 are driven by the external controller to move the limiting plates 7, so that the two sets of limiting plates 7 clamp the cutting blade. Then, the grinding wheel 5 is used to process the cutting blade. The cylinder 1 outside the fixed frame 2 is driven by the external controller to move the drive frame 3 bolted to its end, so that the drive frame 3 drives the grinding wheel 5 in the bracket 16 to contact the cutting blade. At the same time, the electric push rod 10 in the drive frame 3 is driven by the external controller to move the bracket 16 fixed by a screw on one side, so that the bracket 16 drives the grinding wheel 5 to move, adjusting the position of the grinding wheel 5. Then, the servo motor A4 in the bracket 16 is controlled by the external controller. The grinding wheel 5 is used to process the cutting tool. At the same time, the servo motor B11 in the base 23 is converted into mechanical energy by the external controller. The servo motor B11 drives the lead screw 14 to rotate. The support sleeve 12 outside the lead screw 14 is limited by the external symmetrical structure and moves laterally outside the lead screw 14. Then, the support plate 13 welded to the outside of the support sleeve 12 drives the moving frame 18 welded to the top to move. After the cutting tool is processed, the cylinder 1 drives the drive frame 3 to move upward, so that the bracket 16 inside the drive frame 3 drives the grinding wheel 5 to separate from the cutting tool. Then, the servo motor C21 outside the moving frame 18 is driven by the external control to drive the drive rod B20 to rotate. Then, the drive rod B20 drives the processing frame 17 at the end to move. At the same time, the processing frame 17 drives one side The drive rod A6 rotates, causing the processing frame 17 to rotate and flip the cutter inside the processing frame 17. Then, the cylinder 1 drives the bracket 16 on the drive frame 3 to move, so that the grinding wheel 5 inside the bracket 16 contacts the cutter surface again, improving the processing efficiency of the cutter. When the processing frame 17 drives the inner cutter to rotate, the cam 19, which is welded to both the drive rod A6 and the drive rod B20, moves outside the pressure roller 22. As the protruding part of the cam 19 separates from the pressure roller 22, the support rod 25 on one side of the pressure roller 22 is released from pressure. The spring 15 in the moving frame 18 is initially in a compressed state. When the support rod 25 is released from pressure, the spring 15 drives the fixed plate 26 to reset. Then, the fixed plate 26 drives the transmission plate 8 on one side to move. The transmission plate 8 moves towards the cutter. As the processing surface moves, when the processing frame 17 rotates to 90 degrees, the cutter inside the processing frame 17 is in a vertical state. At this time, the pressure roller 22 on the support rod 25 is completely separated from the protrusion on the cam 19, so that the brush 24 inside the transmission plate 8 contacts the cutter. The cam 19 has symmetrical protrusions on both sides. As the moving frame 18 rotates, the pressure roller 22 on the support rod 25 contacts the protrusion on the other side of the cam 19. Then the support rod 25 drives the transmission plate 8 to move. The transmission plate 8 drives the fixed plate 26 to compress the spring 15 inside the moving frame 18. When the processing frame 17 rotates to 180 degrees, the cutter inside the processing frame 17 is flipped. At this time, the transmission plate 8 moves to the initial position, which facilitates the cleaning of the debris processed on the cutter.
