Description

Technical Field

[0001] The present invention belongs to the technical field of tool machining, and in particular relates to a tool machining device and a machining method. Background Art

[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods.

[0003] Tool processing and grinding equipment is specialized equipment used for manufacturing and grinding various cutting tools. Cutting tools play a vital role in industrial production, improving machining accuracy and production efficiency. Therefore, tool processing and grinding equipment is widely used. Tool processing and grinding equipment plays a vital role in modern manufacturing. This equipment enables efficient manufacturing and processing of various cutting tools, achieving high-quality, efficient, and intelligent production, providing technical support for the development and progress of modern industry.

[0004] Chinese patent CN101722409A discloses a tool processing method, which includes first milling a blank to form a tool with a blade and a chip removal groove; then smoothing the fine and sharp cuts on the surface of the tool after milling; and then hardening the tool; thereby making the surface of the tool smoother, increasing its service life and improving its cutting efficiency. The above-mentioned grinding step utilizes a tool grinder to grind the tool, and the tool grinder includes a machine, a grinding barrel, a drive motor and a clamping mechanism. The grinding barrel is rotatably mounted on the machine, and abrasive can be placed therein. The drive motor can drive the grinding barrel to rotate. The clamping mechanism is coupled to the machine and is located above the grinding barrel. It can clamp a plurality of tools and allow the tools to rotate in the grinding barrel; so that the tool can grind a smooth surface and the grinding quality can be more stable.

[0005] Tool grinding equipment can usually only grind one side of the tool's blade during the grinding process. The grinding process is inefficient, and it is difficult to control the quality of the polished tool on both sides, resulting in unevenness. If the polished blade surface is replaced back and forth manually, the grinding quality can be guaranteed, but manual grinding is time-consuming, labor-intensive and inefficient. At the same time, since the tool is relatively sharp, manual flipping will pose a certain safety hazard during the grinding process.

[0016] The present invention further provides a tool processing method, which uses any one of the tool processing devices described above and comprises the following steps:

[0017] S1, the elastic force of the rubber strip causes the outer ends of the two rotating strips to separate from each other, and the outer ends of the two rotating strips cause the two movable rods to be respectively at the top and bottom of the vertical slot, fixing and limiting the tool, and making the inner side edge of the tool correspond to the opening on the front side of the clamping frame, and inserting the inner side edge of the tool into the clamping frame through the opening. When the inner side edge of the tool contacts the rubber strip, the inner side edge of the tool pushes the rubber strip to move, and the rubber strip pulls the inner end of the rotating strip under the action of the pushing force. At this time, the two rotating strips rotate, and the two rotating strips approach each other at the outer ends of the rotation and cause the two movable rods to contact the top and bottom surfaces of the tool respectively. The screw is matched with the through slot so that the screw is at the leftmost side of the through slot. The screw is matched with the two rotating strips, so that the two movable rods can clamp the tool surface, and the inner ends of the two rotating strips can limit the tool, thereby limiting the inner edge of the tool inside the clamping frame;

[0018] S2. Start the cylinder. The cylinder pushes the movable plate at the output end to move. During the movement, the movable plate uses the rack on the bottom to drive the rotating frame to rotate on the surface of the threaded rod. Due to the spiral effect of the rotating frame and the threaded rod, the rotating frame can move back and forth on the surface of the threaded rod. When the rotating frame moves, it uses the side bars to push the movable plate to move synchronously. The movable plate then drives the tail of the cylinder to move synchronously inside the horizontal groove of the side plate. At this time, start the motor, and the motor drives the grinding table to rotate;

[0019] S3. When the rotating frame rotates, the rotating frame uses the gear and the limited teeth to rotate the rotating plate, and the rotating plate uses the clamping device to drive the tool to closely contact the inclined groove surface of the grinding table, which is convenient for grinding the outer edge of the tool;

[0020] S4. When the top surface and bottom surface of the outer edge of the tool contact the bevel groove surface of the upper boss and the bevel groove surface of the lower boss respectively, the reaction force of the bevel groove surface on the tool causes the tool to deflect, and the extrusion pressure of the bevel groove surface of the upper boss on the top surface of the outer edge of the tool causes the inner edge of the tool to move upward inside the clamping frame, and the extrusion pressure of the bevel groove surface of the lower boss on the bottom surface of the outer edge of the tool causes the inner edge of the tool to move downward inside the clamping frame, which can increase the contact area between the top surface and bottom surface of the outer edge of the tool and the bevel groove surface, thereby increasing the grinding edge area of ​​the outer edge of the tool;

[0021] S5. After the outer edge of the tool is polished, the entire processing equipment is restored. At this time, the outer edge of the tool is in a horizontal state, and the tool is separated from the polishing table, which makes it convenient to pull the tool out of the clamping frame to complete the polishing of the cutting edge of the outer edge of the tool.

[0022] The technical effects and advantages of the present invention are as follows:

[0023] 1. When the rotating rack of the present invention rotates, the rotating rack uses the gear and the limited teeth to rotate the rotating plate, and the rotating plate uses the clamping device to drive the tool to closely contact the inclined groove surface of the grinding table, so as to facilitate the grinding of the top and bottom surfaces of the outer edge of the tool respectively.

[0024] 2. In the present invention, when the top surface and bottom surface of the outer edge of the tool are in contact with the bevel surface of the upper boss and the bevel surface of the lower boss respectively, the reaction force of the bevel surface on the tool causes the tool to deviate, and the extrusion force of the bevel surface of the upper boss on the top surface of the outer edge of the tool causes the inner side of the tool to move up inside the clamping frame, thereby increasing the extrusion force between the top surface of the outer edge of the tool and the bevel surface of the upper boss, and the extrusion force of the bevel surface of the lower boss on the bottom surface of the outer edge of the tool causes the inner side of the tool to move down inside the clamping frame, which can improve the top and bottom surfaces of the outer edge of the tool. The contact area with the bevel groove surface increases the edge area of ​​the outer side of the tool for grinding; and the torsional force of the first torsion spring and the cooperation of the gear and the limiting teeth make the outer side top surface of the tool and the bevel groove surface of the upper boss alternately fit and closely contact, and the outer side bottom surface of the tool and the bevel groove surface of the lower boss move back and forth during the close contact process, which makes it convenient for the grinding table to finely grind the outer side top surface of the moving tool during the rotation process, thereby improving the grinding effect of the outer side top surface of the tool.

[0025] When the two movable rods tightly clamp the tool, the screw cannot continue to move leftward in the through slot, which is convenient for clamping tools of different thicknesses and improving the adaptability of the clamping frame to tools of different thicknesses.

[0026] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention.

DETAILED DESCRIPTION

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention provides a tool processing device and a processing method, such as Figure 1-2When the tool is in the working state, the upper end of the cam 5 is moved along the top of the cam 5, and the lower end of the cam 5 is moved along the top of the cam 5, so that the tool 8 can be adjusted according to the working state of the tool 8. When the tool is in the working state, the upper end of the cam 5 is moved along the top of the cam 5, and the upper end of the cam 5 is moved along the top of the cam 5, so that the tool 8 can be adjusted according to the working state of the tool 8. The cylinder 4 works to drive the movable plate 6 to move. At this time, the movable plate 6 cooperates with the adjusting device to make the top and bottom surfaces of the outer edge of the tool 8 on the grinding table 9, which can increase the contact force between the outer edge of the tool 8 and the grinding table 9 and improve the grinding effect of the outer edge of the tool 8.

[0036] exist Figure 1 and Figure 2 In the figure, a movable groove 10 is provided at the center of the top surface of the bracket 7, and a threaded rod 11 is provided inside the movable groove 10. The adjusting device includes a rotating frame 12, which is screwed onto the surface of the threaded rod 11. Gears are annularly fixed to the circumferential sides of the ends of the rotating frame 12. A rack 13 is provided on the bottom surface of the movable plate 6, which meshes with the gears. Side bars 14 are provided on both sides of the movable plate 6, and the inner surfaces of the side bars 14 correspond to the end surfaces of the rotating frame 12. The cylinder 4 drives the movable plate 6 at the output end to move. During the movement, the movable plate 6 uses the rack 13 on the bottom surface to drive the rotating frame 12 to rotate on the surface of the threaded rod 11. Due to the spiral effect of the rotating frame 12 and the threaded rod 11, the rotating frame 12 can move back and forth on the surface of the threaded rod 11. When the rotating frame 12 moves, the side bars 14 push the movable plate 6 to move synchronously. The movable plate 6 then drives the tail of the cylinder 4 to move synchronously inside the transverse groove 3 of the side plate 2.

[0037] exist Figure 2 and Figure 3In the embodiment, the adjusting device further comprises a sleeve 15, the top of the sleeve 15 is movably sleeved on the surface of the rotating frame 12, a rotating rod 16 is provided through the center of the sleeve 15, and rotating plates 17 are fixedly connected at both ends of the rotating rod 16, a plurality of limiting teeth 18 corresponding to the gears of the rotating frame 12 are provided on the circumferential side of the rotating plate 17, a partition 19 is provided at the center of the sleeve 15, the rotating rod 16 passes through the partition 19, and the inner sides of the two rotating plates 17 are provided with first torsion springs 20 correspondingly connected to the partition 19, and the first torsion springs 20 are sleeved on the surface of the rotating rod 16. When the rotating frame 12 rotates counterclockwise, the rotating frame 12 cooperates with the limiting teeth 18 to make the rotating plate 17 rotate clockwise. When the rotating plate 17 drives the rotating rod 16 to rotate at the center of the partition 19, the staggered rotation of the rotating plate 17 and the partition 19 twists the first torsion spring 20. The rotating plate 17 uses the adjusting device to make the outer edge of the tool 8 deflect upward. The top surface of the outer edge of the tool 8 is in close contact with the grinding table 9, which is convenient for grinding the top surface of the outer edge of the tool 8. When the gear of the rotating frame 12 and the top of the limiting teeth 18 of the rotating plate 17 are in close contact with each other, the rotating plate 17 is in close contact with the grinding table 9, which is convenient for grinding the top surface of the outer edge of the tool 8. After separation, the gear of the rotating frame 12 can no longer limit the rotating plate 17. At this time, the torsional force of the first torsion spring 20 causes the rotating plate 17 to rotate counterclockwise until the top of the limiting tooth 18 of the rotating plate 17 contacts the gear of the rotating frame 12 again. The gear of the rotating frame 12 cooperates with the limiting tooth 18 again to cause the rotating plate 17 to rotate clockwise. At this time, the outer edge top surface of the tool 8 and the grinding table 9 are alternately fitted and in close contact. The grinding table 9 can finely grind the outer edge top surface of the moving tool 8 during the rotation process.

[0038] exist Figure 2 and Figure 3 In the embodiment, the bottom of the sleeve 15 is provided with a raised plate, and the top surface of the base plate 1 is provided with a groove 21 corresponding to the raised plate. A limiting rod 22 is provided within the groove 21. A spring 23 is sleeved on the surface of the limiting rod 22, and the ends of the spring 23 are fixedly connected to the two end surfaces of the groove 21 respectively. The center of the spring 23 is fixedly connected to the raised plate at the bottom of the sleeve 15. The spiral effect of the rotating frame 12 and the threaded rod 11 causes the raised plate at the bottom of the sleeve 15 to squeeze the spring 23 on one side and pull the spring 23 on the other side during the movement of the sleeve 15 within the groove 21. When the sleeve 15 moves in the opposite direction, the elastic force of the two springs 23 provides additional power for the reverse movement of the sleeve 15, which conveniently reduces the pressure between the side bar 14 and the end surface of the rotating frame 12 during the reverse movement of the sleeve 15.

[0039] exist Figure 2-Figure 4In the embodiment, the outer sides of the two rotating plates 17 are fixedly connected to support rods 24. The adjustment device also includes a clamping device comprising a clamping frame 25. The inner side of the tool 8 is correspondingly inserted into the interior of the front side of the clamping frame 25. Connecting rods 26 are fixedly connected to the rear ends of the clamping frame 25. The two connecting rods 26 are respectively connected to the two support rods 24. The diameter of the connecting rods 26 is the same as that of the support rods 24. The bottom ends of the connecting rods 26 are fixedly connected to the clamping strips. The bottom ends of the support rods 24 are provided with slots that match the clamping strips. The ends of the two support rods 24 are penetrated by a clamping rod 27. The center of the clamping rod 27 is fixedly connected to the clamping frame 25 by a fixing rod 28. A second torsion spring 29 is sleeved on the surface of the clamping rod 27. When the clamping frame 25 and the tool 8 deflect upward, the slots of the support rods 24 can restrain the clamping strips of the connecting rods 26, so that the support rods 24 and the connecting rods 26 are always aligned. When the clamping frame 25 and the tool 8 deviate downward, the reaction force of the grinding table 9 on the outer side bottom surface of the tool 8 limits the tool 8. At this time, the rotating plate 17 drives the support rod 24 to rotate counterclockwise, and the clamping strip of the connecting rod 26 cannot limit the clamping groove of the support rod 24. The end of the fixed rod 28 limits the center of the second torsion spring 29. At this time, the end of the support rod 24 rotates on the surface of the clamping rod 27 and then twists the second torsion spring 29. The torsional force of the second torsion spring 29 increases the contact force between the outer side bottom surface of the tool 8 and the inclined groove surface of the lower boss 36, which facilitates the grinding of the outer side bottom surface of the tool 8.

[0040] exist Figure 4 and Figure 5In the embodiment, the front side of the clamping frame 25 is provided with an opening corresponding to the tool 8, and the front side of the clamping frame 25 is provided with a vertical slot 30, and the vertical slot 30 runs through the entire clamping frame 25, and the opening is correspondingly connected to the vertical slot 30, and the top and bottom of the inner side of the vertical slot 30 are provided with movable rods 31, and both ends of the movable rod 31 are fixedly connected with a turning bar 32, and the inner ends of the two turning bars 32 are fixedly connected by rubber strips 33, and the inner side edge of the tool 8 corresponds to the concave surface of the rubber strip 33, and the rubber strip 33 is inside the clamping frame 25, and the surfaces of the two turning bars 32 are provided with through grooves, and the surfaces of the two turning bars 32 are correspondingly connected by screws 34, and the screws 34 respectively run through the through slots of the two turning bars 32. The inner side of the tool 8 is aligned with the opening on the front side of the clamping frame 25, and the inner side of the tool 8 is inserted into the clamping frame 25 through the opening. When the inner side of the tool 8 contacts the rubber strip 33, the inner side of the tool 8 pushes the rubber strip 33 to move, and the rubber strip 33 pulls the inner end of the rotating bar 32 under the action of the driving force. At this time, the two rotating bars 32 rotate, and the two rotating bars 32 approach each other at the outer ends of the rotation and make the two movable rods 31 contact the top and bottom surfaces of the tool 8 respectively. The screw 34 is used to cooperate with the through slot so that the screw 34 is at the leftmost side of the through slot. The screw 34 is used to cooperate with the two rotating bars 32, so that the two movable rods 31 can clamp the surface of the tool 8, and the inner ends of the two rotating bars 32 can limit the tool 8, thereby limiting the inner side of the tool 8 inside the clamping frame 25.

[0041] After the tool 8 is installed inside the clamping frame 25, the position of the screw 34 inside the through slot can be adjusted according to the thickness of the tool 8. When the two movable rods 31 tightly clamp the tool 8, the screw 34 cannot continue to move to the left inside the through slot, which facilitates the clamping of tools 8 of different thicknesses and improves the adaptability of the clamping frame 25 to tools 8 of different thicknesses.

[0042] exist Figure 1 and Figure 3In the embodiment, the grinding table 9 includes an upper boss 35 and a lower boss 36. The bottom surface of the upper boss 35 is fixedly connected to the top surface of the lower boss 36, and the bottom surface diameter of the upper boss 35 is the same as the top surface diameter of the lower boss 36. The outer edge of the tool 8 is located between the upper boss 35 and the lower boss 36. The bottom surface diameter of the lower boss 36 is larger than the top surface diameter of the upper boss 35. Both the upper boss 35 and the lower boss 36 are provided with bevel surfaces, and the outer edge of the tool 8 contacts the bevel surfaces. When the motor is driven to rotate the grinding table 9, the upper boss 35 and the lower boss 36 cause the bevel surfaces to rotate, and the two bevel surfaces can grind the top and bottom surfaces of the outer edge of the tool 8. When the top surface and bottom surface of the outer edge of the tool 8 contact the bevel surface of the upper boss 35 and the bevel surface of the lower boss 36 respectively, the reaction force of the bevel surface on the tool 8 causes the tool 8 to deviate, and the extrusion pressure of the bevel surface of the upper boss 35 on the top surface of the outer edge of the tool 8 causes the inner side of the tool 8 to move upward on the inner side of the clamping frame 25, and the extrusion pressure of the bevel surface of the lower boss 36 on the bottom surface of the outer edge of the tool 8 causes the inner side of the tool 8 to move downward on the inner side of the clamping frame 25, which can increase the contact area between the top and bottom surfaces of the outer edge of the tool 8 and the bevel surface, and increase the cutting edge area of ​​the outer edge of the tool 8.

[0043] When the rotating frame 12 rotates counterclockwise, the rotating frame 12 cooperates with the limiting teeth 18 to make the rotating plate 17 rotate clockwise. When the rotating plate 17 drives the rotating rod 16 to rotate at the center of the partition 19, the staggered rotation of the rotating plate 17 and the partition 19 twists the first torsion spring 20. The rotating plate 17 uses the connection effect of the support rod 24 and the connecting rod 26 to make the clamping frame 25 and the outer side of the tool 8 offset upward. The top surface of the outer side of the tool 8 is in close contact with the inclined groove surface of the upper boss 35, which is convenient for grinding the top surface of the outer side of the tool 8. After the top of the limiting teeth 18 is separated, the gear of the rotating frame 12 can no longer limit the rotating plate 17. At this time, the torsional force of the first torsion spring 20 causes the rotating plate 17 to rotate counterclockwise until the top of the limiting teeth 18 of the rotating plate 17 contacts the gear of the rotating frame 12 again. The gear of the rotating frame 12 cooperates with the limiting teeth 18 again to cause the rotating plate 17 to rotate clockwise. At this time, the top surface of the outer edge of the tool 8 and the bevel surface of the upper boss 35 are alternately fitted and in close contact. The grinding table 9 can finely grind the top surface of the outer edge of the moving tool 8 during the rotation process.

[0044] When the rotating frame 12 rotates clockwise, the rotating frame 12 cooperates with the limiting teeth 18 to make the rotating plate 17 rotate counterclockwise. The misaligned rotation of the rotating plate 17 and the partition 19 causes the first torsion spring 20 to twist. The rotating plate 17 uses the connection effect of the support rod 24 and the connecting rod 26 to make the clamping frame 25 and the outer edge of the tool 8 deviate downward. The bottom surface of the outer edge of the tool 8 is in close contact with the inclined groove surface of the lower boss 36. The movable plate 6 continues to make the rotating frame 12 rotate clockwise. At this time, the rotating plate 17 drives the support rod 24 to rotate counterclockwise. Due to the contact of the inclined groove of the lower boss 36 with the bottom surface of the outer edge of the tool 8, the clamping frame 25 uses the fixing rod 28 to limit the clamping rod 27, and the end of the fixing rod 28 limits the center of the second torsion spring 29. At this time, the end of the support rod 24 rotates on the surface of the clamping rod 27 to The torsion spring 29 is twisted, and the torsional force of the second torsion spring 29 increases the contact force between the outer side bottom surface of the tool 8 and the bevel surface of the lower boss 36, which is convenient for grinding the outer side bottom surface of the tool 8. When the gear of the rotating frame 12 is separated from the bottom of the limiting teeth 18 of the rotating plate 17, the gear of the rotating frame 12 can no longer continue to limit the rotating plate 17. At this time, the torsional force of the first torsion spring 20 causes the rotating plate 17 to rotate clockwise until the top of the limiting teeth 18 of the rotating plate 17 contacts the gear of the rotating frame 12 again. The gear of the rotating frame 12 cooperates with the limiting teeth 18 again to cause the rotating plate 17 to rotate counterclockwise. At this time, the outer side bottom surface of the tool 8 and the bevel surface of the lower boss 36 move back and forth in close contact, which makes it convenient for the grinding table 9 to finely grind the outer side top surface of the moving tool 8 during rotation.

[0045] The present invention also provides a tool processing method, which uses the tool processing equipment described above and includes the following steps:

[0046] S1, the elastic force of the rubber strip 33 causes the outer ends of the two rotating strips 32 to separate from each other, and the outer ends of the two rotating strips 32 cause the two movable rods 31 to be respectively at the top and bottom of the vertical slot 30, fixing the tool 8, and making the inner side of the tool 8 correspond to the opening on the front side of the clamping frame 25, and inserting the inner side of the tool 8 into the clamping frame 25 through the opening. When the inner side of the tool 8 contacts the rubber strip 33, the inner side of the tool 8 pushes the rubber strip 33 to move, and the rubber strip 33 pushes the rotating strip 32 under the action of the pushing force. 2, the inner ends of the two rotating bars 32 rotate, and the two rotating bars 32 approach each other at the outer ends of the rotation, so that the two movable rods 31 contact the top and bottom surfaces of the tool 8 respectively. The screw 34 is matched with the through slot, so that the screw 34 is located at the leftmost side of the through slot. The screw 34 cooperates with the two rotating bars 32, so that the two movable rods 31 can clamp the surface of the tool 8, and the inner ends of the two rotating bars 32 can limit the tool 8, thereby limiting the inner side of the tool 8 inside the clamping frame 25.

[0047] S2. Start the cylinder 4. The cylinder 4 works to push the movable plate 6 at the output end to move. During the movement, the movable plate 6 uses the rack 13 on the bottom to drive the rotating frame 12 to rotate on the surface of the threaded rod 11. Due to the spiral effect of the rotating frame 12 and the threaded rod 11, the rotating frame 12 can move back and forth on the surface of the threaded rod 11. When moving, the rotating frame 12 uses the side bars 14 to push the movable plate 6 to move synchronously. The movable plate 6 then drives the tail of the cylinder 4 to move synchronously inside the transverse groove 3 of the side plate 2. At this time, the motor is started, and the motor drives the grinding table 9 to rotate.

[0048] S3. When the rotating frame 12 rotates, the rotating frame 12 uses the gear and the limiting teeth 18 to rotate the rotating plate 17. The rotating plate 17 uses the clamping device to drive the tool 8 to closely contact the inclined groove surface of the grinding table 9, which is convenient for grinding the outer edge of the tool 8.

[0049] S4. When the top surface and bottom surface of the outer side of the tool 8 contact the bevel surface of the upper boss 35 and the bevel surface of the lower boss 36 respectively, the reaction force of the bevel surface on the tool 8 causes the tool 8 to deviate, and the extrusion pressure of the bevel surface of the upper boss 35 on the top surface of the outer side of the tool 8 causes the inner side of the tool 8 to move up on the inner side of the clamping frame 25, and the extrusion pressure of the bevel surface of the lower boss 36 on the bottom surface of the outer side of the tool 8 causes the inner side of the tool 8 to move down on the inner side of the clamping frame 25, which can increase the contact area between the top and bottom surfaces of the outer side of the tool 8 and the bevel surface, and increase the grinding edge area of ​​the outer side of the tool 8.

[0050] S5. After the outer edge of the tool 8 is polished, the entire processing equipment is restored. At this time, the outer edge of the tool 8 is in a horizontal state, and the tool 8 is separated from the polishing table 9, which makes it convenient to pull the tool 8 out from the inside of the clamping frame 25 to complete the polishing of the cutting edge of the outer edge of the tool 8.
