Description

Technical Field

[0001] The present invention relates to the technical field of tool manufacturing and forming, and more specifically, it relates to a machining equipment for manufacturing and forming machine tools Background Art

[0002] In the field of machine tool tool manufacturing, precise tool forming directly affects product quality and production efficiency. However, the existing tool grinding technology has limitations, mainly reflected in the rigid fixing mode of fixture design. Most of the fixture systems widely used in the current market adopt a fixing mechanism to firmly lock the tool in a preset position. Although this fixing mode ensures the accuracy of the machining position, it also results in a very limited contact area between the tool and the grinding wheel. Usually, only a specific part of the tool can be ground. This "point contact" grinding method is not only inefficient and requires frequent adjustment of the tool position to complete comprehensive grinding, but also easily forms uneven machining marks and sharpness differences on the tool surface. More critically, this fixing mode cannot simulate the change of force distribution and angle fine-tuning in the manual grinding process, resulting in insufficient treatment of the transition area at the edge of the tool, affecting the overall performance and service life of the tool

[0003] When professional craftsmen manually grind tools, they can make real-time and fine adjustments to the pressure applied to the tool based on rich experience and tactile feedback, and can flexibly change the contact angle and position during the grinding process. This progressive and adaptive force distribution can not only ensure uniform stress on all parts of the tool, but also carry out targeted treatment according to material characteristics and wear conditions. In contrast, the existing mechanical fixture systems lack this adaptability and progressive adjustment ability and cannot achieve continuous transitional grinding from the root to the tip of the tool. Due to uneven force distribution, it often leads to over-grinding in some areas of the tool and insufficient grinding in other areas, and even causes changes in material properties due to local overheating during high-speed grinding, restricting the consistency and reliability of tool performance Summary of the Invention

This configuration creates an adjustable elastic force control system. The fixed sleeves equidistantly installed on the springs serve as the insertion points of the transverse rod, enabling the transverse rod to fix the springs at different positions, thereby changing the length and quantity of the spring segments participating in the work.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a machine tool tool manufacturing and forming processing device, which has the following beneficial effects:

[0018] Through the designed spring group and push block system, the device realizes the control and dynamic adjustment of the force applied to the tool. When the tool contacts the grinding disk, the spring will produce elastic deformations of different degrees according to the change of the position of the moving table, so as to adaptively adjust the pressure during the grinding process. This progressive force change simulates the force distribution characteristics of manual grinding, making the force on each part of the tool more uniform, effectively avoiding the problems of local over-grinding or under-grinding caused by traditional fixed fixtures. At the same time, the number and position of the spring group can be selectively activated through the cooperation of the transverse rod and the fixed sleeve, enabling the operator to preset an appropriate pressure range according to different tool materials, shapes and grinding requirements, greatly improving the flexibility and adaptability of processing.

[0019] The transverse rod is quickly inserted and firmly locked through the cooperation of the side sleeve and the arc-shaped spring. The operator only needs to rotate the rotating disk and use the contact between the tapered sleeve and the top block to push the thrust bearing, and then the radial contraction of the arc-shaped spring can be activated to firmly clamp the handle. This design not only provides a stable working state but also maintains the convenience of adjustment, greatly reducing the operation time and labor intensity.

[0020] Generally speaking, this machine tool cutter manufacturing and forming processing equipment, through its innovative variable force mechanism and flexible angle adjustment system, makes the cutter grinding process closer to the fineness and quality of manual grinding, while maintaining the high efficiency and consistency of mechanical processing. It not only improves the uniformity and accuracy of cutter grinding, but also greatly expands the scope of application. Brief Description of the Drawings

[0034] Please refer to Figures 1 to 9, a machine tool cutter manufacturing and forming processing device, including a machine frame 11 and a grinding wheel 12 rotatably connected to the machine frame 11, and a moving table 13 is fitted and installed on the machine frame 11; it also includes a variable force mechanism. The variable force mechanism includes a fixed block 21 fixedly installed on the moving table 13. A plurality of springs 22 are installed on the fixed block 21. The other ends of the plurality of springs 22 are installed with a push block 23. An intermediate wheel 24 is rotatably installed on the moving table 13. A synchronous block 25 is meshed and installed between the push block 23 and the intermediate wheel 24. Two connecting blocks 26 are installed at the upper end of the synchronous block 25. A positioning rod 27 and a tail rod 28 are respectively installed at both ends of the two connecting blocks 26. The tail rod 28 is inserted into the push block 23. A plurality of positioning holes 29 are equidistantly arranged on the intermediate wheel 24. The positioning rod 27 is inserted into the positioning hole 29. The variable force mechanism also includes bilateral rods 210 installed on both sides of the push block 23. A push plate 211 is fixedly installed on the two bilateral rods 210. A pull plate 212 is slidably connected to the two bilateral rods 210. The pull plate 212 is connected to the two connecting blocks 26. Two guide rods 213 are installed at the lower end of the pull plate 212. The two guide rods 213 are slidably connected to the push block 23. A tension spring 214 is sleeved on the guide rod 213. One end of the tension spring 214 is connected to the pull plate 212, and the other end of the tension spring 214 is connected to the push block 23. Two fixing sleeves 215 are respectively equidistantly installed on the plurality of springs 22. Two side sleeves 216 are installed on the side wall of the moving table 13. A transverse rod 217 is slidably connected in the side sleeve 216. The transverse rod 217 is inserted into the plurality of fixing sleeves 215. A handle 218 is coaxially installed on the transverse rod 217. The handle 218 is inserted into the side sleeve 216. A side groove 219 is opened on the side wall of the side sleeve 216. An arc spring 220 is fixedly installed in the side sleeve 216. The arc spring 220 is slidably connected in the side groove 219, and the arc spring 220 presses on the handle 218. The other ends of the plurality of arc springs 220 are connected to a follower ring 221. The follower ring 221 is slidably connected in the side sleeve 216. A thrust bearing 222 is installed on the follower ring 221. A rotating disk 223 is fitted and installed on the thrust bearing 222. A plurality of top blocks 224 are installed on the side sleeve 216. A gradient sleeve 225 is installed on the side of the rotating disk 223 close to the top block 224. The top block 224 abuts against the gradient sleeve 225.

[0035] When grinding the tool body 33, first install the tool body 33 on the tool rest 31, and then press it on the tool body 33 through the vertical bolt 34 to ensure the synchronous fixation of the tool body 33 and the tool rest 31. At this time, the intermediate wheel 24 meshes with the rotating wheel 32, and the synchronous block 25 meshes with the intermediate wheel 24 and the push block 23 respectively. The tail rod 28 is inserted into the push block 23, and the positioning rod 27 is inserted into the positioning hole 29. Therefore, the push block 23 and the intermediate wheel 24 are fixedly connected synchronously. Since the fixed block 21 at the other end is fixedly installed on the moving table 13, the spring 22 will apply an elastic force to the intermediate wheel 24. As the moving table 13 moves, it will drive the tool body 33 to move towards the grinding disc 12. First, the tool body 33 is attached to the grinding disc 12 for grinding. As the moving table 13 continues to move, pressure will be applied. At this time, the force between the tool body 33 and the grinding disc 12 will be transmitted to the intermediate wheel 24 and offset by the elastic force of the spring 22. Since the spring 22 can deform, as a greater pressure is applied, the spring 22 will produce a greater deformation and generate a greater pressure. By rotating the tool rest 31, the tool body 33 can be driven to rotate accordingly, so the grinding position can be adjusted, thereby improving the grinding effect.

[0036] When the initial grinding angle of the tool body 33 needs to be adjusted, first refer to Figure 3 , the operator's hand pinches the pull plate 212 and the push plate 211. Since one end of the double-sided rod 210 is fixedly connected to the push block 23 and the other end of the double-sided rod 210 is connected to the push plate 211, as the operator's hand applies a pulling force, it will drive the pull plate 212 to move upward. Since the connecting block 26 is connected to the pull plate 212, it will then drive the positioning rod 27 and the tail rod 28 to release the connection with the positioning hole 29 and the push block 23 respectively, and the synchronous block 25 will also move upward accordingly. Therefore, the engagement with the intermediate wheel 24 will be released. At this time, the rotating wheel 32 is not engaged and can be freely adjusted in direction. When the adjustment is completed, release the pull plate 212, and under the action of the tension spring 214, the positioning rod 27 is inserted into the corresponding positioning hole 29, thus completing the adjustment process, enabling the tool body 33 to be ground at different angles.

[0037] When the pressure of the tool body 33 pressing on the grinding disc needs to be adjusted, insert the transverse rod 217 into the corresponding side sleeve 216 and fixed sleeve 215 according to different situations. At this time, the spring 22 between the fixed block 21 and the transverse rod 217 is in a fixed state and cannot apply an elastic force. Only the spring 22 between the transverse rod 217 and the push block 23 can apply an elastic force. Since the spring 22 that applies the force changes, the elastic force generated by the same displacement will change. At this time, corresponding adjustments can be made according to different situations to meet the corresponding requirements.

[0038] When it is necessary to fix the cross bar 217 to different side sleeves 216, first insert the cross bar 217 into the side sleeve 216 and the corresponding fixing sleeve 215. As the handle 218 is continuously pushed into the side sleeve 216, then rotate the rotating disc 223, and then the gradient sleeve 225 will press against the top block 224, so it will push the thrust bearing 222 downward. At this time, the thrust bearing 222 will only transmit the thrust to drive the follower ring 221 to slide downward. One end of the plurality of arc-shaped springs 220 is fixedly connected to the side sleeve 216, and the other end of the arc-shaped spring 220 is connected to the follower ring 221. As pressure is applied, the arc-shaped spring 220 will be compressed and thus contract towards the axis. The arc-shaped spring 220 presses against the side wall of the handle 218, so the handle 218 will be fixed, thus completing the fixing process of the cross bar 217. When it is necessary to unlock, only move in the reverse direction, and thus complete the fixing and unlocking process.

[0039] The steering mechanism includes a tool rest 31 rotatably connected to the moving platform 13. A rotating wheel 32 is installed on the tool rest 31, and the rotating wheel 32 meshes with the intermediate wheel 24. The steering mechanism also includes a tool body 33 installed on the tool rest 31. Two vertical bolts 34 are threadedly connected to the tool rest 31, and the vertical bolts 34 press on the tool body 33. A motor 35 is installed on the machine frame 11, and a belt 36 is engaged and connected to the extending end of the motor 35. The other end of the belt 36 is engaged with the grinding disc 12.

[0040] In all the solutions mentioned above, for the connection between two components, welding, bolt and nut connection, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered.
