Description

Technical Field

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

[0002] A diamond tool grinding machine is a device specifically designed for grinding and polishing diamond tools (such as diamond cutting bits, surgical blades, etc.). Its core objective is to improve the cutting edge sharpness, surface finish, and geometric accuracy of the tools through grinding. A typical grinding machine consists of a grinding mechanism and a clamping mechanism. Patent document CN 214322748U discloses a tool grinding fixture, which allows the cutting bits to be placed into a groove manually or by a robotic arm. A pressure component drives a pressure rod to press the cutting bits firmly into the groove, simplifying the operation and improving clamping efficiency.

[0003] However, the existing cutting tool grinding fixture still has certain drawbacks in the process of grinding cutting tools in conjunction with the grinding mechanism. For example, it can only grind one side of the cutting tool. When it is necessary to grind the other side, the cutting tool needs to be removed and then clamped again, which reduces the overall grinding efficiency. Utility Model Content

[0004] This utility model mainly provides a diamond cutting tool grinding machine, which solves the problem that the existing technology can only grind one side of the cutting tool. When the other side needs to be ground, the cutting tool needs to be removed and then clamped, which reduces the overall grinding efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A diamond cutting tool grinding machine includes a cutting tool clamping mechanism and a cutting tool grinding mechanism. The cutting tool clamping mechanism includes a grinding frame with a support platform on it, and a mating hole on the support platform. A lifting assembly is mounted on the grinding frame, and a lifting platform is mounted on the lifting assembly. The lifting platform moves up and down via the lifting assembly. A rotating assembly is mounted on the lifting platform, and a disassembly / assembly frame is mounted on the rotating assembly. A cutting tool positioning frame is detachably connected to the disassembly / assembly frame, and a slot for placing cutting tools is provided on the disassembly / assembly frame. A cutting tool anti-detachment assembly is mounted on the disassembly / assembly frame. A cutting tool grinding support is provided at the front end of the support platform to support the cutting tools. In use, the cutting inserts are placed in the slots of the cutting insert positioning frame manually or by a robotic arm. Then, the cutting insert anti-detachment component is activated to fix the position of the cutting inserts. Next, the cutting insert grinding mechanism is activated to grind the cutting inserts. When it is necessary to reverse the cutting inserts, the lifting component moves the lifting platform up and down to adjust the vertical height of the cutting inserts. Then, the rotating component operates to rotate the disassembly frame, realizing the horizontal flipping of the cutting inserts. After flipping, the lifting component lowers all components to grind different sides of the cutting inserts. During the grinding process, the cutting insert grinding support supports the cutting inserts to ensure grinding stability. In this process, if it is necessary to grind the cutting inserts on the side or at an angle, the lifting component can also move all components up and down, and the rotating component can rotate the cutting inserts at a certain angle to grind the cutting inserts at that angle. This structure enables the positioning, height adjustment, and flipping of the cutting bits during the grinding process, eliminating the need for frequent manual removal and re-clamping of the bits, thus significantly improving grinding efficiency. Simultaneously, the coordinated operation of all components ensures the stability of the cutting bits during grinding, guaranteeing high-quality grinding. The support platform provides support and limits for each component, and the mating holes on the support platform allow the anti-detachment component of the flipped cutting bits to pass through, ensuring that the disassembly frame and cutting bit positioning frame remain supported by the support frame even after flipping. Furthermore, the cutting bit grinding support provides underside support for the cutting bits, effectively ensuring the stability and accuracy of the grinding process.

[0007] Furthermore, the grinding frame is provided with a lifting groove; the lifting assembly includes a lifting screw rotatably connected to the lifting groove, a lifting guide rod fixedly connected to the lifting groove, and a lifting motor mounted on the grinding frame to drive the lifting screw to rotate; the lifting platform is threadedly connected to the lifting screw, and the lifting platform is slidably connected to the lifting guide rod. In use, the lifting motor is started, and its output shaft drives the lifting screw to rotate within the lifting groove; since the lifting platform is threadedly connected to the lifting screw and slidably connected to the lifting guide rod, the lifting guide rod acts as a guide and limiter, thereby cooperating with the lifting screw to drive the lifting platform to move up and down. This structure enables stable lifting of the lifting platform, thereby precisely controlling the vertical position of the cutting edge, ensuring the accuracy and effect of grinding; at the same time, the electric drive method has a high degree of automation, reducing manual operation and improving production efficiency.

[0008] Furthermore, the rotating assembly includes a rotating rod rotatably connected to the lifting platform and a rotating motor mounted on the lifting platform for driving the rotating rod to rotate; the disassembly frame is located at the end of the rotating rod. In use, the rotating motor drives the rotating rod to rotate on the lifting platform, which in turn drives the disassembly frame to rotate. This structure allows the cutting inserts to flexibly flip and rotate in the horizontal direction without needing to remove and reinstall them from the fixture, greatly shortening the time required for flipping and rotating the cutting inserts and significantly improving the efficiency of double-sided or multi-sided grinding. At the same time, the electrically controlled rotation angle ensures the accuracy of the cutting insert flipping angle, providing conditions for precise grinding.

[0009] Furthermore, the blade anti-detachment assembly includes a sub-frame mounted on the disassembly frame and an anti-detachment cylinder mounted on the sub-frame corresponding to the position above the placement slot. In use, after the blade is placed into the placement slot of the blade positioning frame, the piston rod of the anti-detachment cylinder extends downwards until the blade is firmly pressed into the placement slot. Throughout the blade grinding process, the anti-detachment cylinder maintains a certain pressure to prevent the blade from shifting or falling off due to vibration, friction, or other factors during grinding. When grinding is complete and the blade needs to be removed, the piston rod of the anti-detachment cylinder retracts, releasing the pressure on the blade. This structure effectively prevents the blade from shifting or falling off during grinding, ensuring the safety and stability of the grinding process. It not only reduces the risk of equipment failure and product scrap due to blade detachment but also improves grinding quality, ensuring the consistency of blade grinding dimensions and surface precision.

[0010] Furthermore, the cutting tool grinding mechanism includes a horizontal displacement module and a lifting module disposed on the horizontal displacement module, wherein a grinding component is disposed on the lifting module. The horizontal displacement module, the lifting module, and the grinding component can all employ existing technologies, as long as they can achieve horizontal displacement, vertical displacement, and cutting tool grinding.

[0011] Beneficial effects: It enables the positioning, height adjustment, and flipping of the cutting blades during the grinding process, eliminating the need for frequent manual removal and re-clamping of the blades, thus significantly improving the grinding efficiency. At the same time, the coordinated work of various components ensures the stability of the cutting blades during grinding, providing a guarantee for high-quality grinding. The support platform also provides support and limit for each component, and the mating holes on the support platform allow the blade anti-dislodgement component to pass through after flipping, ensuring that the disassembly frame and blade positioning frame can still be supported by the support frame after flipping.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, the diamond cutting tool grinding machine of this embodiment includes a tool clamping mechanism 1 and a tool grinding mechanism 2; the tool clamping mechanism 1 includes a grinding frame 101, a support platform 102 is provided on the grinding frame 101, and a mating hole 103 is provided on the support platform 102; a lifting assembly 104 is provided on the grinding frame 101, and a lifting platform 105 is provided on the lifting assembly 104, the lifting platform 105 being raised and lowered by the lifting assembly 104; the lifting... A rotating assembly 106 is provided on the platform 105, and a disassembly frame 107 is provided on the rotating assembly 106. The disassembly frame 107 rotates by the rotating assembly 106. A cutting tool positioning frame 108 is detachably connected to the disassembly frame 107. The cutting tool positioning frame 108 has a placement groove for placing cutting tools. A cutting tool anti-detachment assembly 109 is provided on the disassembly frame 107. A cutting tool grinding support 110 for supporting cutting tools is provided at the front end of the support platform 102. The grinding frame 101 has a lifting groove 1011; the lifting assembly 104 includes a lifting screw 1041 rotatably connected to the lifting groove 1011, a lifting guide rod 1042 fixedly connected to the lifting groove 1011, and a lifting motor 1043 mounted on the grinding frame 101 for driving the lifting screw 1041 to rotate; the lifting platform 105 is threadedly connected to the lifting screw 1041, and the lifting platform 105 is slidably connected to the lifting guide rod 1042. The rotating assembly 106 includes a rotating rod 1061 rotatably connected to the lifting platform 105, and a rotating motor 1062 mounted on the lifting platform 105 for driving the rotating rod 1061 to rotate; the disassembly / assembly frame 107 is located at the end of the rotating rod 1061. The blade anti-detachment assembly 109 includes a sub-frame 1091 mounted on the disassembly frame 107 and an anti-detachment cylinder 1092 mounted on the sub-frame 1091 corresponding to the position above the placement slot. The blade grinding mechanism 2 includes a horizontal displacement module 201, a lifting module 202 mounted on the horizontal displacement module 201, and a grinding assembly 203 mounted on the lifting module 202.

[0019] In use, the cutting blades are placed in the slot of the cutting blade positioning frame 108 manually or by a robotic arm. Then, the cutting blade anti-detachment component 109 (anti-detachment cylinder 1092) is activated to fix the position of the cutting blades. Then, the cutting blade grinding mechanism 2 is activated to grind the cutting blades. When it is necessary to reverse the cutting blades, the lifting component 104 (lifting screw 1041, lifting guide rod 1042, lifting motor 1043) drives the lifting platform 105 to move up and down to adjust the height of the cutting blades in the vertical direction. Then, the rotating component 106 (rotating rod 1061) is activated. The rotating motor 1062 operates, driving the disassembly frame 107 to rotate, thereby turning the blade in the horizontal direction. After turning, the lifting component 104 drives each component to descend, thus grinding different surfaces of the blade. During the grinding process, the blade grinding support 110 supports the blade to ensure the stability of the grinding. In this process, if it is necessary to grind the blade on the side or at an angle, the lifting component 104 can drive each component to rise and fall, and the rotating component 106 can drive the blade to rotate at a certain angle, thereby grinding the blade at that angle. This structure enables the positioning, height adjustment, and flipping of the cutting bits during the grinding process, eliminating the need for frequent manual removal and re-clamping of the cutting bits, thus significantly improving grinding efficiency. Simultaneously, the coordinated operation of all components ensures the stability of the cutting bits during grinding, guaranteeing high-quality grinding. The support platform 102 provides support and limits for each component, and the mating holes 103 on the support platform 102 facilitate the passage of the anti-detachment component 109 after flipping, ensuring that the disassembly frame 107 and the cutting bit positioning frame 108 remain supported by the support platform 102 even after flipping. Furthermore, the cutting bit grinding support 110 provides support for the lower side of the cutting bits, further ensuring the stability and accuracy of the grinding process.
