Description

Technical Field

[0001] This application relates to the field of auxiliary processing equipment technology, and more specifically, to a limiting disk for assisting in the processing of PCD or PCBN composite sheets. Background Technology

[0002] PCD (polycrystalline diamond composite) and PCBN (polycrystalline cubic boron nitride composite) are two types of superhard materials. They are composite materials formed by sintering diamond or cubic boron nitride (CBN) micro powder with metal binders (such as cobalt, nickel, etc.) onto a cemented carbide matrix using high temperature and high pressure technology.

[0003] Existing composite sheet processing auxiliary devices use radially movable clamps to abut and limit the outer peripheral sidewalls of the composite sheet. This limiting and fixing method cannot adapt to composite sheets of different thicknesses. If the composite sheet is too thin, the contact area between the clamp and the sidewall of the composite sheet is insufficient. During the processing of the composite sheet, the friction force of the processing equipment can overcome the abutment force of the clamp, causing the composite sheet to move with the processing equipment, resulting in the failure of the limiting mechanism and the inability to effectively process the end face of the composite sheet. At the same time, the composite sheet limiting structure is unstable, which can easily cause the composite sheet to collide with the clamp during processing, resulting in edge chipping and the production of waste sheets.

[0004] Therefore, we propose a limiting disk for assisting in the processing of PCD or PCBN composite sheets to solve the existing problems. Utility Model Content

[0032] like Figures 1 to 8As shown, a limiting disk for assisting in the processing of PCD or PCBN composite sheets includes a base 1, a support assembly 6 on the top surface of the base 1, and a fixing ring 2 mounted on the top surface of the support assembly 6. The fixing ring 2 includes a first ring body 21 and a second ring body 22 arranged concentrically. A movable disk 3, coaxial with the fixing ring 2 and slidably connected to the first ring body 21 and the second ring body 22, is provided inside the first ring body 21 and between the first ring body 21 and the second ring body 22. Multiple sets of vacuum suction cups 5 are equidistantly distributed on the movable disk 3. A drive connection assembly 7 is provided on the support assembly 6. The output end is driven and connected to the movable disk 3. Multiple sets of clamping components 4 are installed on the outer periphery of the second ring body 22. The non-clamping end of the clamping component 4 is driven and connected to the movable disk 3. In use, the fixing ring 2 is installed above the base 1 by the support component 6 to support the composite sheet. The bottom surface of the composite sheet is adsorbed by the vacuum suction cup 5 set on the movable disk 3. The movable disk 3 can be driven by the drive connection component 7 to move the composite sheet along the longitudinal axis, so that the bottom surface of the composite sheet is in close contact with the fixed disk. At the same time, the clamping component 4 located on the outer periphery of the second ring body 22 moves to clamp and fix the composite sheet.

[0033] Furthermore, the movable disc 3 includes a first disc 31 installed in the inner circle of the first ring 21 and a second disc 32 installed between the first ring 21 and the second ring 22. The first disc 31 and the second disc 32 can slide within the fixed ring 2 and their positions can be adjusted by driving the drive connection component 7 to accommodate composite sheets of different diameters.

[0034] Furthermore, the support assembly 6 includes a limiting plate 61, a first support column 62, and a second support column 63. The limiting plate 61 is disposed between the top surface of the base 1 and the bottom surface of the fixing ring 2, and the top surface of the limiting ring is provided with multiple protrusions that are fixedly connected to the first ring body 21 and the second ring body 22 respectively. The first support column 62 is fixedly disposed between the bottom surface of the limiting plate 61 and the base 1, and the second support column 63 is fixedly installed between the bottom surface of the second ring body 22 and the base 1. In use, the limiting plate 61 is connected to the fixing ring 2 through the protrusions, and the first support column 62 and the second support column 63 support the limiting plate 61 and the second ring body 22 respectively, providing stable support for the entire processing limiting device.

[0035] Furthermore, the drive connection assembly 7 includes a drive cylinder 71 fixedly mounted on the bottom end face of the limiting plate 61. The output end of the drive cylinder 71 is positioned facing the base 1, and a connecting plate 72 is fixedly mounted on the end of the output end. A first connecting rod 73 and a second connecting rod 74 are fixedly mounted on the top surface of the connecting plate 72. The other end of the first connecting rod 73 movably passes through the limiting plate 61 and is fixedly connected to the first disc body 31. The other end of the second connecting rod 74 movably passes through the limiting plate 61 and is fixedly connected to the second disc body 32. In use, the drive cylinder 71 drives the first disc body 31 through the connecting plate 72 and the connecting rods. The first disc 31 and the second disc 32 are moved to synchronously adjust their positions, making the first disc 31 and the second disc 32 protrude from the end faces of the first ring 21 and the second ring 22 to facilitate the installation of the composite sheet. After the composite sheet is placed and installed, the vacuum suction cup 5 generates negative pressure to firmly adsorb the composite sheet, so that the first disc 31 and the second disc 32, driven by the drive cylinder 71, drive the composite sheet to gradually approach the end faces of the first ring 21 and the second ring 22, so that the composite sheet fits against the end faces of the first ring 21 and the second ring 22.

[0036] Furthermore, rubber rings 51 are installed at the top of multiple sets of vacuum suction cups 5, and several second rubber pads 8 are installed at equal intervals at the top of the first ring body 21 and the second ring body 22. In use, the vacuum suction cups 5 fix the composite sheet by adsorption force. The rubber rings 51 are used to seal the gap between the vacuum suction cups 5 and the composite sheet and also play a buffering role. When the composite sheet comes into contact with the first ring body 21 and the second ring body 22, the second rubber pads 8 play a buffering role between the composite sheet and the first ring body 21 and the second ring body 22 to avoid the bottom surface of the composite sheet being scratched during processing.

[0037] Furthermore, multiple clamping components 4 are equidistantly arranged on the outer periphery of the second ring body 22. In use, the multiple clamping components 4 work together to ensure uniform clamping of the composite sheet, and the clamping and releasing of the composite sheet is achieved by the movement of the gripper 43.

[0038] Furthermore, the clamping assembly 4 includes a first hinge seat 41 fixed to the bottom of the second disc 32 and a second hinge seat 44 fixed to the outer periphery of the second ring 22. A connecting rod 42 is hinged to the first hinge seat 41, and a gripper 43 is hinged to the other end of the connecting rod 42. The gripper 43 is hinged to the second hinge seat 44. In use, the first hinge seat 41 installed at the bottom of the second disc 32 drives the connecting rod 42 to make the gripper 43 move around the second hinge seat 44, thereby realizing the opening and closing movement of the gripper 43, which presses down to cooperate with the second ring 22 to clamp the composite sheet or lifts up to separate from the end face of the second ring 22 to release the composite sheet.

[0039] Furthermore, the gripper 43 includes a first rod 431 and a second rod 433. The first rod 431 and the second rod 433 are integrally connected at opposite ends and form an angle between them. The other end of the first rod 431 is movably hinged to a first hinge seat 41, and a hinge shaft 432 is provided in the middle of the first rod 431, which is movably hinged to the second hinge seat 44. The other end of the second rod 433 is positioned above the second ring 22, and a first rubber pad 434 is provided on the end face of the other end of the second rod 433. In use, it is driven... The cylinder 71 drives the second disc 32 to move downward, causing the connecting rod 42, which is connected to the second disc 32 at one end through the first hinge seat 41, to drive the integrated first rod 431 and second rod 433 to rotate around the second hinge seat 44. This causes the end of the second rod 433 away from the first rod 431 to move toward the top end face of the second ring 22, thereby gradually clamping the composite sheet. The first rubber pad 434 provided on the second rod 433 is used to buffer when the second rod 433 contacts the end face of the composite sheet, so as to avoid scratching the composite sheet.

[0040] Furthermore, the included angle between the first rod 431 and the second rod 433 is 120°. Maintaining a 120° included angle between the first rod 431 and the second rod 433 makes the opening and closing or clamping of the gripper 43 more flexible, thereby improving the stability and reliability of clamping and installing the composite piece.

[0041] Furthermore, the top end face of the base 1 is provided with multiple equally spaced mounting slots 11, and the mounting slots 11 are provided with threaded connection holes that penetrate the base 1. When in use, it is convenient to install and fix the limiting plate. The limiting plate is fixed to the processing equipment through the threaded connection holes to ensure the stability of the entire processing limiting device during the processing.

[0042] The working principle of this utility model is as follows: Before processing, the base 1 is installed on the workbench of the processing equipment. The mounting groove 11 of the base 1 is aligned with the fixing hole of the workbench. The base 1 is tightly connected and fixed to the workbench of the processing equipment by bolts passing through the threaded connection holes in the mounting groove 11. A composite sheet is placed on the movable plate 3. The vacuum suction cup 5 generates negative pressure to adsorb the bottom surface of the composite sheet. Then, the drive cylinder 71 is started, so that the movable plate 3 drives the composite sheet to gradually approach the end faces of the first ring 21 and the second ring 22 along the longitudinal axis, so that the composite sheet contacts the top surface of the first ring 21 and the second ring 22. At the same time, the drive cylinder 71 is activated. Driven by the first ring 22, the gripper 43 moves, causing the gripper 43 to engage with the second ring 22 to clamp the composite sheet. After clamping, the output end of the drive cylinder 71 maintains a constant stroke, ensuring that during processing, the gripper 43 always applies a downward pressure perpendicular to the end face of the composite sheet. This prevents the composite sheet from moving during polishing and cutting of its upper surface, which could damage it. After processing, the output end of the drive cylinder 71 retracts, the first disc 31 and the second disc 32 rise, and the gripper 43 opens. The vacuum suction cup 5 is then closed to remove the processed composite sheet.

[0043] The above specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
