A positioning structure for a cutting device used in the production of diamond heat dissipation materials

Abstract

This utility model relates to a positioning structure for a cutting device used in the production of diamond heat dissipation materials. It includes a mounting component mounted on the cutting device, on which four positioning components are provided for positioning and protecting the material. This positioning structure for the cutting device uses a linkage transmission between a gear ring and gears to achieve synchronous radial movement of the four positioning components, automatically centering circular or rectangular composite materials without the need for manual clamp replacement. The positioning blocks are centrally symmetrically distributed, and the contact surfaces of adjacent positioning blocks are perpendicular, simultaneously adapting to both circumferential positioning of circles and right-angle edge positioning of rectangles. Furthermore, the flexible graphite pads on the surface of the positioning blocks provide cushioning, preventing scratches or indentations on the surface of the diamond heat dissipation material from hard clamps, making it particularly suitable for brittle composite materials. The high-temperature resistance of the flexible graphite pads effectively resists localized heat generated during the cutting process, preventing thermal damage to the material.

Description

Technical Field

[0001] This utility model relates to the field of diamond heat dissipation material production technology, specifically a positioning structure for a cutting device used in the production of diamond heat dissipation materials. Background Technology

[0002] The production of diamond heat dissipation materials typically involves raw material preparation, diamond synthesis and processing, and post-processing. The entire process includes raw material selection and pretreatment, diamond synthesis and growth, molding and processing, post-processing, and performance testing. Post-processing involves grinding the molded material with diamond abrasives to remove excess parts such as the outer sheath. Then, a cutting device is used to cut the diamond composite material from the alloy substrate, and the cut surface is polished to a bright finish to meet the product's size and surface quality requirements. Commonly used cutting methods in the post-processing cutting steps include mechanical cutting, thermal cutting, electrical discharge cutting, and chemical or physical-assisted cutting. Mechanical cutting methods include grinding wheel cutting and blade cutting.

[0003] In current technologies, common composite materials are rectangular or circular. When machining diamond heat dissipation materials using mechanical cutting methods, a high-speed rotating grinding wheel is used to remove the bonding layer between the alloy substrate and the composite material interface through grinding.

[0004] In actual processing, the clamping process reveals significant compatibility defects. For rectangular composite materials, symmetrical fixtures can achieve efficient positioning by clamping from both sides. However, when the processing object is changed to circular composite materials, it is necessary to manually change the special fixtures. Frequent fixture changes not only prolong the processing preparation time and reduce production efficiency, but may also affect the positioning accuracy due to operational errors. Therefore, a positioning structure for a cutting device for diamond heat dissipation material production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a positioning structure for a cutting device used in the production of diamond heat dissipation materials. This structure offers the advantage of protecting the composite material and solves the problem of removing the bonding layer between the alloy substrate and the composite material interface through grinding. In actual processing, symmetrical clamps are used to fix both sides of the composite material, and then a high-speed rotating grinding wheel is controlled to contact the bonding layer and perform grinding. However, the vibration and prestress generated by grinding are transmitted to the edges and corners of the composite material, which can easily lead to edge cracking of the diamond composite material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning structure for a cutting device used in the production of diamond heat dissipation materials, comprising an installation component disposed on the cutting device, wherein the installation component is provided with four positioning components for positioning and protecting the material, and the installation component is provided with a transmission component for controlling the movement of the positioning components;

[0007] The positioning component includes a positioning block, on which a flexible graphite pad is fixedly installed, and a limiting groove is formed on the positioning block;

[0008] The transmission component includes a gear ring and four gears, with the gears meshing with the gear ring and the gears meshing with the positioning block. A connecting plate is fixedly connected to the outer surface of the gear ring.

[0009] The mounting component includes a mounting plate, on the top of which a circular platform is fixedly mounted, and a gear is rotatably mounted inside the circular platform. One end of a connecting plate passes through the circular platform. A support column rotatably connected to the gear is fixedly mounted on the mounting plate. A limiting block slidably connected to a limiting groove is fixedly mounted on the mounting plate. A driving component for controlling the rotation of the connecting plate around the central axis of the circular platform is provided on the mounting plate.

[0010] Furthermore, the driving component includes an electric push rod, which is fixedly mounted on the mounting plate. The telescopic end of the electric push rod is fixedly connected to a connecting sleeve, and a connecting column connected to the connecting plate is rotatably mounted inside the connecting sleeve.

[0011] Furthermore, the connecting plate has a slot, and one end of the connecting post extends through and into the inside of the slot, with the slot and the connecting post being slidably connected.

[0012] Furthermore, a guide strip is fixedly installed on the top of the mounting plate, and a guide groove is provided on the positioning block, with the guide groove slidably connected to the guide strip.

[0013] Furthermore, the four positioning components are symmetrical about the central axis of the truncated ring, the number of the support columns matches the number of gears, and the number of the limiting blocks and guide strips matches the number of positioning components.

[0014] Furthermore, the side of the positioning block on which the flexible graphite pad is installed contacts the side of the adjacent positioning block, and the two contacting surfaces in the positioning block are perpendicular to each other.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The positioning structure of this cutting device for diamond heat dissipation material production achieves synchronous radial movement of four positioning components through the linkage transmission of a toothed ring and gears. It automatically centers on circular or rectangular composite materials without the need for manual clamp replacement. The positioning blocks are centrally symmetrically distributed, and the contact surfaces of adjacent positioning blocks are perpendicular. It can simultaneously adapt to the circumferential positioning of circles and the right-angle edge positioning of rectangles. Moreover, the flexible graphite pad on the surface of the positioning block has a buffering effect, which can prevent hard clamps from scratching or indenting the surface of the diamond heat dissipation material. It is especially suitable for brittle composite materials. Furthermore, the high-temperature resistance of the flexible graphite pad can effectively resist the local heat generated during the cutting process and prevent thermal damage to the material.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-6The positioning structure of a cutting device for producing diamond heat dissipation material in this embodiment includes a mounting component 1 disposed on the cutting device, four positioning components 3 disposed on the mounting component 1 for positioning and protecting the material, and a transmission component 2 disposed on the mounting component 1 for controlling the movement of the positioning components 3.

[0026] Example 2: Please refer to Figure 1-6 Based on Embodiment 1, the positioning component 3 includes a positioning block 31, on which a flexible graphite pad 32 is fixedly installed, and a limiting groove 33 is formed on the positioning block 31.

[0027] The transmission component 2 includes a gear ring 21 and four gears 24, and the gears 24 mesh with the gear ring 21 and mesh with the positioning block 31. A connecting plate 22 is fixedly connected to the outer surface of the gear ring 21.

[0028] Mounting component 1 includes mounting plate 11, with a circular platform 12 fixedly mounted on the top of mounting plate 11, and gear 24 rotatably mounted inside the circular platform 12. One end of connecting plate 22 passes through the circular platform 12. A support column 13 rotatably connected to gear 24 is fixedly mounted on mounting plate 11. A limiting block 14 slidably connected to limiting groove 33 is fixedly mounted on mounting plate 11. A driving component 4 for controlling the rotation of connecting plate 22 around the central axis of circular platform 12 is provided on mounting plate 11.

[0029] The top of the mounting plate 11 is fixedly equipped with a guide strip 15, and the positioning block 31 is provided with a guide groove 34. The guide groove 34 is slidably connected with the guide strip 15. The cooperation between the limiting block 14 and the limiting groove 33, and the guide strip 15 and the guide groove 34, strictly limits the movement trajectory of the positioning block 31, further improving the positioning accuracy and reducing the error of grinding and cutting.

[0030] In addition, the four positioning components 3 are symmetrical about the central axis of the annular platform 12. The number of support columns 13 and gears 24 are matched. The number of limiting blocks 14 and guide bars 15 are matched with the number of positioning components 3. The four positioning components 3 adopt a central symmetrical design. Through the meshing transmission of the toothed ring 21 and the four gears 24, synchronous movement can be achieved, ensuring uniform clamping force on the material, effectively preventing material displacement caused by uneven force, and limiting the edges and corners of the composite material.

[0031] It should be noted that the side of the positioning block 31 on which the flexible graphite pad 32 is installed is in contact with the side of the adjacent positioning block 31, and the two contacting surfaces of the positioning block 31 are perpendicular to each other. This design can not only adapt to the positioning of various shaped materials such as rectangles, but also avoid the corners of the positioning block 31 from scratching the material. Moreover, the flexible graphite pad 32 can resist the high temperature generated during cutting and absorb the vibration during the cutting process.

[0032] Using the above technical solution, the rotation of the connecting plate 22 will drive the gear ring 21 to rotate together. The rotation of the gear ring 21 will drive the four gears 24 to rotate synchronously around the support column 13 inside the annular platform 12. The rotation of the gears 24 will drive the positioning block 31 to move. Since the four positioning components 3 are symmetrical about the central axis of the annular platform 12, during synchronous movement, the flexible graphite pad 32 on the positioning block 31 will gradually approach and contact the material, ultimately stabilizing and positioning the composite material, and protecting the edges and corners of the composite material, avoiding the edge and corner cracking of the composite material due to the vibration and prestress generated by grinding.

[0033] Example 3: Please refer to Figure 1-6 Based on Embodiment 2, the driving component 4 includes an electric push rod 41, which is fixedly installed on the mounting plate 11. The telescopic end of the electric push rod 41 is fixedly connected to a connecting sleeve 42, and a connecting column 43 connected to the connecting plate 22 is rotatably installed inside the connecting sleeve 42.

[0034] The connecting plate 22 has a slot 23, and one end of the connecting post 43 extends through and into the inside of the slot 23. The slot 23 and the connecting post 43 are slidably connected, so that the linear motion of the electric push rod 41 is transformed into the arc-shaped trajectory motion of the connecting plate 22 through the slot 23 and the connecting post 43.

[0035] Using the above technical solution, the composite material is placed at the center of the annular platform 12. After the electric push rod 41 of the driving component 4 is started, its telescopic end will drive the connecting sleeve 42 and the internally rotatably installed connecting column 43 to move. Since the connecting column 43 extends into the groove 23 of the connecting plate 22 and the two are slidably connected, the movement of the connecting column 43 will cause the connecting plate 22 to rotate around the central axis of the annular platform 12.

[0036] The working principle of the above embodiments is as follows:

[0037] When the positioning structure of the cutting device for diamond heat dissipation material production is used, the composite material is placed at the center of the circular stage 12. After the electric push rod 41 of the drive component 4 is started, its telescopic end will drive the connecting sleeve 42 and the internally rotatably installed connecting column 43 to move. Since the connecting column 43 extends into the slot 23 of the connecting plate 22 and the two are slidably connected, the movement of the connecting column 43 will cause the connecting plate 22 to rotate around the central axis of the circular stage 12.

[0038] The connecting plate 22 is fixedly connected to the gear ring 21. The rotation of the connecting plate 22 will drive the gear ring 21 to rotate together. Since the gear ring 21 meshes with four gears 24, the rotation of the gear ring 21 will drive these four gears 24 to rotate synchronously around the support column 13 inside the annular platform 12.

[0039] Gear 24 meshes with positioning block 31. The rotation of gear 24 will drive positioning block 31 to move. During the movement of positioning block 31, limiting block 14 on mounting plate 11 slides in limiting groove 33 of positioning block 31, and guide strip 15 on mounting plate 11 slides in guide groove 34 of positioning block 31. The double guide constraint ensures that positioning block 31 moves smoothly along the predetermined trajectory. The four positioning components 3 are symmetrical about the central axis of the truncated ring 12. During synchronous movement, flexible graphite pad 32 on positioning block 31 will gradually approach and contact the material, and finally stably clamp and position the composite material.
