Description

Technical Field

[0001] This utility model relates to the field of ceramic parts processing technology, specifically to a high-precision automated rotary grinding device for ceramic parts. Background Technology

[0002] For circular ceramic components in the semiconductor field, specific groove structures (such as circular grooves, radial grooves, or irregular grooves) can be formed by grinding the ceramic parts, which can be used to store abrasive grains, guide fluid, or enhance heat dissipation.

[0003] When processing ceramic parts for grinding grooves, the circular ceramic parts are manually clamped and fixed, and the groove shape is ground using a linear reciprocating grinding wheel. This method relies on the operator's experience and is prone to uneven groove depth. For example, CN213917524U discloses a high-efficiency ceramic processing grinding device, which includes a platform. This high-efficiency ceramic processing grinding device uses a first motor to drive a first threaded rod to rotate within the platform, causing the slider to be pushed by the thread and move the placement block left and right. When the placement block moves to the left to the outside of the protective cover, the ceramic object is placed in the placement groove. The second motor on the right side of the placement block drives the second threaded rod inside to rotate, causing the two movable blocks to be pushed by the thread and move the two clamping plates towards each other, clamping the ceramic object. Then, the placement block is controlled to move directly below the grinding machine. The position of the grinding machine is adjusted using various control mechanisms in the control box to achieve automatic grinding of the ceramic object. Compared with traditional manual grinding, the fixation is more stable, the speed is faster, and the dust is blocked by the protective cover, achieving the purpose of convenient use.

[0004] However, when the above-mentioned device grinds ceramic parts, it uses opposing clamping blocks for rigid fixation. After the round ceramic parts are fixed, local stress concentration is prone to occur, which can easily cause chipping or micro-cracks. Especially when grinding grooves at high speed, centrifugal force will aggravate the uneven force on the clamping surface, resulting in the destruction of the integrity of the edge of the processed surface, which can easily damage the ceramic parts and lead to low processing quality.

[0005] Therefore, it is of great importance to design a high-precision automated rotary grinding device for ceramic parts to solve the above-mentioned defects. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model designs a high-precision automated rotary grinding device for ceramic parts. This device aims to solve the technical problem that in the existing technology, when grinding ceramic parts, the use of opposing clamping blocks for rigid fixation easily damages the ceramic parts, resulting in low processing quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-precision automated rotary grinding device for ceramic parts includes a base, a support frame fixed to the rear end of the top of the base, a grinding machine slidably connected to the top of the support frame, a lifting mechanism installed between the grinding machine and the support frame, a moving stage fixedly installed at the front end of the top of the base, a linear moving mechanism installed on the top of the moving stage, a housing fixedly installed on the top of the linear moving mechanism, a turntable rotatably connected to the top of the housing, and a positioning component fixedly installed on the top of the turntable.

[0009] The positioning component includes a fixed frame fixedly installed on the top of the turntable, a rotating frame movably installed above the fixed frame, and multiple sets of positioning blocks slidably connected between the rotating frame and the fixed frame at equal intervals. A cylinder is hinged to the right end of the fixed frame, and the output end of the cylinder is hinged to the rotating frame through a connector.

[0010] As a preferred embodiment of this utility model, the tops of the multiple sets of positioning blocks are slidably connected to the rotating frame via guide grooves, and the bottoms of the multiple sets of positioning blocks are slidably connected to the fixing frame via sliding grooves.

[0011] As a preferred embodiment of this utility model, the lifting mechanism includes a lifting rack fixedly installed on the surface of the support frame, a first motor fixedly installed on the right side of the grinder, a drive gear fixedly installed on the drive end of the first motor, and the drive gear meshing with the lifting rack.

[0012] As a preferred embodiment of this utility model, locking blocks are slidably connected to both the left and right ends of the back of the grinder, and locking studs are installed at the rear ends of the two sets of locking blocks. One end of the locking stud is rotatably connected to one set of locking blocks, and the other end of the locking stud is threadedly connected to the other set of locking blocks.

[0013] As a preferred embodiment of this utility model, the linear motion mechanism includes a slide table slidably connected to the top of the moving platform, an adjusting screw rotatably connected to the inner side of the moving platform, the bottom of the slide table being connected to the adjusting screw via a screw nut, and a second motor being fixedly installed at the front end of the moving platform, with the drive end of the second motor being fixedly connected to the front end of the adjusting screw.

[0014] As a preferred embodiment of this utility model, guide rails are fixedly installed at both ends of the top of the mobile platform, and both ends of the slide are slidably connected to the guide rails via slide blocks.

[0015] As a preferred embodiment of this utility model, a third motor is fixedly installed inside the chassis, the drive end of the third motor is fixedly connected to the bottom of the turntable, and a chip removal groove is provided inside the turntable.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, through the coordinated design of the support frame, grinding machine, lifting mechanism, moving platform, linear moving mechanism, and chassis and turntable, when performing grooving operation on circular ceramic parts, the first motor drives the drive gear to rotate, and the height of the grinding machine is adjusted under the connection of the lifting rack, thereby automatically adjusting the grooving depth. The second motor drives the adjusting screw to rotate, and the slide table moves back and forth under the connection of the screw and nut. The slide table slides stably on the guide rail through the sliding seat, thereby adjusting the position of the grooving groove by moving the circular ceramic part back and forth. The third motor drives the turntable to rotate, and by driving the turntable to rotate one revolution and then return to its original position, the requirements of rotary grooving are met, thus satisfying the requirements of automated grooving.

[0018] 2. In this utility model, through the design of the positioning component, when the circular ceramic part is grooved, after it is placed inside the fixed frame, the cylinder is started and the rotating frame is driven to rotate through the connector. Multiple sets of positioning blocks move synchronously under the guidance of the guide groove and the slide groove, thereby using multiple sets of positioning blocks to evenly fix the outer side of the circular ceramic part. This not only makes the operation simple and convenient, but also ensures the uniformity of the force on the clamping surface, thereby avoiding damage to the circular ceramic part and ensuring the processing quality.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1-6 This utility model provides a technical solution:

[0028] A high-precision automated rotary grinding device for ceramic parts includes a base 1, a support frame 2 fixed to the rear end of the top of the base 1, a grinding machine 3 slidably connected to the top of the support frame 2, a lifting mechanism 4 installed between the grinding machine 3 and the support frame 2, a moving platform 5 fixedly installed at the front end of the top of the base 1, a linear moving mechanism 6 installed on the top of the moving platform 5, a housing 7 fixedly installed on the top of the linear moving mechanism 6, a turntable 8 rotatably connected to the top of the housing 7, and a positioning component 9 fixedly installed on the top of the turntable 8.

[0029] First, in this embodiment, the specific structure of the positioning component 9 is as follows:

[0030] The positioning assembly 9 includes a fixed frame 901 fixedly mounted on the top of the turntable 8. A rotating frame 902 is movably mounted above the fixed frame 901. Multiple positioning blocks 903 are slidably connected between the rotating frame 902 and the fixed frame 901 at equal intervals. A cylinder 904 is hinged to the right end of the fixed frame 901. The output end of the cylinder 904 is hinged to the rotating frame 902 via a connector 905. The tops of the multiple positioning blocks 903 are slidably connected to the rotating frame 902 via guide grooves 906, and the bottoms of the multiple positioning blocks 903 are slidably connected to the rotating frame 902 via sliding grooves 906. 7 is slidably connected to the fixed frame 901. When grooving a circular ceramic part, after placing it inside the fixed frame 901, the cylinder 904 is activated to drive the rotating frame 902 to rotate through the connector 905. Multiple sets of positioning blocks 903 move synchronously under the guidance of the guide groove 906 and the slide groove 907, thereby using multiple sets of positioning blocks 903 to evenly fix the outer side of the circular ceramic part. This not only makes the operation simple and convenient, but also ensures the uniformity of the force on the clamping surface, thus avoiding damage to the circular ceramic part and ensuring the processing quality.

[0031] Then, the lifting mechanism 4 includes a lifting rack 401 fixedly installed on the surface of the support frame 2. A first motor 402 is fixedly installed on the right side of the grinding machine 3. A drive gear 403 is fixedly installed on the drive end of the first motor 402, and the drive gear 403 meshes with the lifting rack 401. When performing the grooving operation on the circular ceramic part, the first motor 402 drives the drive gear 403 to rotate. Under the connection of the lifting rack 401, the height of the grinding machine 3 is adjusted, thereby automatically adjusting the grooving depth.

[0032] Furthermore, locking blocks 404 are slidably connected to both ends of the back of the grinder 3. Locking studs 405 are installed at the rear ends of the two sets of locking blocks 404. One end of the locking stud 405 is rotatably connected to one set of locking blocks 404, and the other end of the locking stud 405 is threadedly connected to the other set of locking blocks 404. When adjusting the height of the grinder 3, the locking stud 405 is rotated first to move and open the two sets of locking blocks 404, so that the front ends of the two sets of locking blocks 404 are disengaged from the inner side of the tooth groove of the lifting rack 401, allowing the grinder 3 to be adjusted normally. After the adjustment is completed, the locking stud 405 is reversed to move the two sets of locking blocks 404 relative to each other. The two sets of locking blocks 404 are then locked into the inner side of the tooth groove of the lifting rack 401 to prevent the grinder 3 from moving, thereby ensuring the stability of the grinding operation.

[0033] Secondly, the linear motion mechanism 6 includes a slide 601 slidably connected to the top of the moving platform 5. An adjusting screw 602 is rotatably connected to the inner side of the moving platform 5. The bottom of the slide 601 is connected to the adjusting screw 602 through a screw nut 603. A second motor 604 is fixedly installed at the front end of the moving platform 5, and the drive end of the second motor 604 is fixedly connected to the front end of the adjusting screw 602. Guide rails 605 are fixedly installed at both ends of the top of the moving platform 5. The left and right ends of the slide 601 are slidably connected to the guide rails 605 through slide blocks 606. During the grinding operation, the second motor 604 drives the adjusting screw 602 to rotate, and under the connection of the screw nut 603, it drives the slide 601 to move back and forth. The slide 601 slides stably on the guide rails 605 through the slide blocks 606, thereby enabling the circular ceramic part to move back and forth to adjust the grinding position.

[0034] Finally, a third motor 701 is fixedly installed inside the chassis 7. The drive end of the third motor 701 is fixedly connected to the bottom of the turntable 8. The turntable 8 has a chip removal groove 801 inside. When grinding the circular ceramic part, the third motor 701 can drive the turntable 8 to rotate. By driving the turntable 8 to rotate one revolution and then return to its original position, the requirements of rotary grinding are met. At the same time, the grinding process is carried out with the help of grinding fluid to rinse, avoid excessive processing temperature and remove ceramic chips. The ceramic chips inside the fixed frame 901 can be discharged through the chip removal groove 801.

[0035] In this embodiment, the specific implementation scenario is as follows: When grooving a circular ceramic part, after placing it inside the fixed frame 901, the cylinder 904 is activated to drive the rotating frame 902 to rotate via the connector 905. Multiple sets of positioning blocks 903 move synchronously under the guidance of the guide groove 906 and the slide groove 907, thereby using multiple sets of positioning blocks 903 to evenly fix the outer side of the circular ceramic part. When grooving the circular ceramic part, the first motor 402 drives the drive gear 403 to rotate, and the height of the grinding machine 3 is adjusted under the connection of the lifting rack 401, thereby automatically adjusting the grooving depth. The second motor 60... 4. The adjusting screw 602 is rotated, and the slide 601 is moved back and forth under the connection of the screw nut 603. The slide 601 slides stably on the guide rail 605 through the slide block 606, so that the circular ceramic part can be moved back and forth to adjust the position of the grinding groove. The third motor 701 can drive the turntable 8 to rotate. By driving the turntable 8 to rotate one revolution and then return to its original position, the requirements of rotating the grinding groove are met. The whole operation process is simple and convenient. This utility model not only has a simple and convenient operation to meet the requirements of automated grinding groove, but also ensures the uniformity of the force on the clamping surface, thereby avoiding damage to the circular ceramic part and ensuring the processing quality.
