Description

Technical Field

[0001] This invention relates to the technical field of cylindrical ceramic clamps, and in particular to a cylindrical ceramic clamping structure. Background Technology

[0002] Cylindrical ceramics are commonly found in vases, teacups, and crucibles, while high-precision ceramics include piezoelectric ceramics and fiber optic ceramic ferrules, making them an indispensable part of modern industrial products.

[0003] In the production of cylindrical ceramics, ensuring a smooth surface and avoiding scratches is a crucial consideration for ceramic processing equipment. To achieve large-scale production and improve efficiency, a constant clamping force mechanism plays a vital role. Specifically, as a transfer mechanism for cylindrical ceramics, the ideal state is for the clamping mechanism to maintain a constant clamping force on the cylindrical ceramics during the clamping and transfer process, thus preventing damage to the ceramic surface.

[0004] For example, Chinese invention patent application CN202111068087.2 discloses a cylindrical ceramic carrier gripper, which includes a base plate, a first slide plate, a second slide plate, a first clamping arm, a second clamping arm, a clamping part, and a clamping mechanism. The first and second slide plates are slidably disposed on the base plate. The clamping part, used to clamp the carrier, is respectively disposed on the first and second clamping arms. The clamping mechanism is disposed on the base plate and is used to drive the first and second slide plates to move inward relative to each other to clamp, and to move outward to release. The clamping mechanism includes a clamping cylinder, a clamping drive rack, a clamping gear, and a clamping driven rack. When the clamping cylinder drives the first and second clamping arms to move closer to each other by clamping the drive rack and the driven rack, the clamping part mounted on the first and second clamping arms clamps and fixes the cylindrical ceramic.

[0005] However, existing gripper structures have the following problems in practical use: the clamping force of the clamping part on the cylindrical ceramic is provided by the clamping cylinder, and the driving force of the clamping cylinder is driven by the air pressure of the cylinder itself. The air pressure fluctuates during production depending on the number of machines used, making it difficult to maintain a balanced driving force. This results in inconsistent pressure when the clamping part holds different cylindrical ceramics, potentially causing scratches on the surface of the cylindrical ceramics due to differences in force. Secondly, the existing gripper structure is too complex, making subsequent equipment maintenance too difficult. Therefore, to solve the above technical problems, the cylindrical ceramic clamping structure of this application is proposed. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cylindrical ceramic clamping structure that can clamp cylindrical ceramics with constant force to avoid scratching the surface due to excessive changes in clamping force, and which is simple in structure and easy to maintain.

The elastic element abuts against the longitudinal sliding plate and the base plate, and is used to push the longitudinal sliding plate to bring the two lateral sliding plates closer together. The driving element is disposed on the base plate, and its output shaft is connected to the longitudinal sliding plate.

[0012] Optionally, the limiting post has a pressure regulating groove along the axial direction, and the cylindrical ceramic clamping structure further includes a pressure regulating assembly.

[0013] Optionally, the pressing block includes a pressing body and a plurality of extension rods. The pressing body is disposed on the pressure sensor, and each of the extension rods is disposed on the outer peripheral wall of the pressing body.

[0016] Optionally, a first slot is formed on each side of the longitudinal sliding plate along the sliding direction, and a first rotating wheel is rotatably provided on each of the two swing blocks, with the two first rotating wheels respectively housed in the two first slots.

[0030] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention.

[0031] like Figure 1 As shown, a cylindrical ceramic clamping structure 10 includes a substrate 100 and a clamping assembly 200. The clamping assembly 200 includes a longitudinal sliding plate 210, an elastic element 220, a driving element 230, two lateral sliding plates 240, and two swing blocks 250. The longitudinal sliding plate 210 is slidably disposed on the substrate 100. Both lateral sliding plates 240 are slidably disposed on the substrate 100, and the sliding direction of the lateral sliding plates 240 is perpendicular to the sliding direction of the longitudinal sliding plate 210. Both swing blocks 250 are rotatably disposed on the substrate 100, and one end of each swing block 250 is connected to one of the two lateral sliding plates 240. The other end of the moving block 250 is connected to the longitudinal slide plate 210. A clamping member 260 is provided on the opposite side surface of the two lateral slide plates 240. The elastic member 220 abuts against the longitudinal slide plate 210 and the base plate 100 respectively. The elastic member 220 is used to push the longitudinal slide plate 210 so that the longitudinal slide plate 210 drives the two lateral slide plates 240 to move closer to each other. The driving member 230 is provided on the base plate 100, and the output shaft of the driving member 230 is connected to the longitudinal slide plate 210. The driving member 230 is used to drive the longitudinal slide plate 210 to slide towards the elastic member 220 so that the two lateral slide plates 240 move away from each other.

[0032] It should be noted that the clamping assembly 200 is mounted on the substrate 100 and is used to clamp and fix the cylindrical ceramic. Specifically, the longitudinal slide plate 210 and the two lateral slide plates 240 are slidably mounted on the substrate 100 via slide rails, wherein the sliding direction of the longitudinal slide plate 210 is perpendicular to the sliding direction of the lateral slide plates 240. Further, a clamping member 260 is mounted on the side of the two lateral slide plates 240 that are close to each other, and the clamping member 260 is used to clamp and fix the cylindrical ceramic. Further, two swing blocks 250 are rotatably mounted on the substrate 100 via bearings. In any one of the swing blocks 250, both ends of the swing block 250 are connected to the longitudinal slide plate 210 and the lateral slide plate 240 respectively. In this way, as the longitudinal slide plate 210 slides, the two swing blocks 250 can simultaneously drive the two lateral slide plates 240 to slide closer to each other or further away from each other. Further, both ends of the elastic member 220 abut against the longitudinal slide plate 210 and the substrate 100 respectively. Thus, under the elastic thrust of the elastic member 220, the longitudinal slide plate 210 slides relative to the substrate 100 in a certain direction, thereby causing the two lateral slide plates 240 to slide closer to each other via the two swing blocks 250, which in turn causes the two clamping members 260 to move closer to each other to jointly clamp the cylindrical ceramic. Further, the drive member 230 is mounted on the substrate 100, and the output shaft of the drive member 230 is connected to the longitudinal slide plate 210, so that the drive member 230 can drive the longitudinal slide plate 210 to slide closer to the elastic member 220. It should be noted that the driving force of the drive member 230 is opposite to the elastic force of the elastic member 220. Therefore, while the elastic member 220 is used to drive the two clamping members 260 closer to each other to clamp and fix the cylindrical ceramic, the drive member 230 is used to drive the two clamping members 260 away from each other to release the cylindrical ceramic.

[0033] The working principle of the above structure is explained below. When clamping a cylindrical ceramic, the cylindrical ceramic clamping structure 10 of this application is driven by the elastic force of the elastic element 220. When releasing the cylindrical ceramic, the driving element 230 reverses the movement of the clamping element 260 to release the cylindrical ceramic. Therefore, when clamping the cylindrical ceramic, the clamping force of the clamping element 260 is applied by the elastic element 220. Compared with the prior art where the force is applied by a cylinder, this avoids the difference in driving force caused by unstable air pressure. Therefore, it ensures that the clamping element 260 clamps the cylindrical ceramic with the same force each time, thus preventing scratches on the surface of the cylindrical ceramic due to excessive clamping force differences. Furthermore, the cylindrical ceramic clamping structure 10 of this application has a simple structure, which facilitates subsequent equipment maintenance and reduces the material input cost of the device.

[0034] like Figure 1As shown, in one embodiment, the drive member 230 includes a motor 231 and a cam 232. The motor 231 is disposed on the base plate 100, and the cam 232 is disposed on the output shaft of the motor 231. The outer peripheral wall of the cam 232 abuts against the longitudinal slide plate 210.

[0035] It should be noted that the motor 231 is fixedly mounted on the substrate 100, and the cam 232 is mounted on the output shaft of the motor 231, so that the motor 231 drives the cam 232 to rotate. The outer peripheral wall of the cam 232 abuts against the end of the longitudinal slide plate 210. Thus, as the cam 232 rotates, its outwardly protruding outer wall pushes the longitudinal slide plate 210 to slide relative to the substrate 100, causing the clamping members 260 to separate and release the cylindrical ceramic. When the outwardly protruding outer wall of the cam 232 no longer pushes the longitudinal slide plate 210, the cam 232 separates from the longitudinal slide plate 210, and the clamping members 260 stably clamp the cylindrical ceramic under the elastic thrust of the elastic member 220. Therefore, by controlling the forward or reverse rotation of the cam 232 via the motor 231, the separation of the clamping members 260 on the lateral slide plate 240 can be reliably controlled. Furthermore, in one embodiment, a reducer is also mounted on the output shaft of the motor 231, and a cam 232 is mounted on the output shaft of the reducer. It should be noted that by setting the cam 232 to rotate to push or release the longitudinal slide plate 210, the clamping member 260 can smoothly clamp the cylindrical ceramic, thereby effectively preventing the cylindrical ceramic from being scratched.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, a rotating wheel 270 is rotatably disposed on the longitudinal sliding plate 210, and the outer peripheral wall of the rotating wheel 270 abuts against the outer peripheral wall of the cam 232.

[0037] It should be noted that in order for the cam 232 to stably push the longitudinal slide plate 210, a roller 270 is installed on the longitudinal slide plate 210. When the cam 232 rotates so that its outward protruding part approaches the longitudinal slide plate 210, the outer peripheral wall of the outward protruding part of the cam 232 abuts against the roller 270. In this way, the roller 270 and the cam 232 roll and rub against each other, thereby improving the sliding stability of the longitudinal slide plate 210.

[0038] like Figure 3 As shown, in one embodiment, a first slot 211 is opened on each side of the longitudinal sliding plate 210 along the sliding direction, and a first rotating wheel 251 is rotatably arranged on each of the two swing blocks 250, and the two first rotating wheels 251 are respectively housed in the two first slots 211.

[0039] It should be noted that, in order to smoothly drive the swing block 250 to rotate when the longitudinal slide plate 210 slides in a straight line, and since the swing block 250 is configured to rotate relative to the base plate 100, a first rotating wheel 251 is installed on the swing block 250. For example, the first rotating wheel 251 is mounted on the swing block 250 via a bearing. Then, a first slot 211 is formed on the side wall of the longitudinal slide plate 210, wherein the first rotating wheel 251 is adapted to the first slot 211. Thus, when the longitudinal slide plate 210 slides, the inner side wall of the first slot 211 pushes against the first rotating wheel 251, thereby driving the swing block 250 to rotate.

[0040] Furthermore, such as Figure 3 As shown, in one embodiment, a second rotating wheel 252 is rotatably provided on the swing block 250, and a second slot 241 is provided on the side wall of the lateral sliding plate 240, and the second rotating wheel 252 is accommodated in the second slot 241.

[0041] Similarly, since the lateral sliding plate 240 moves linearly and the swing block 250 rotates, a second rotating wheel 252 is installed on the side of the swing block 250 closest to the lateral sliding plate 240 to ensure a stable connection. A second slot 241 is then created on the lateral sliding plate 240, allowing the second rotating wheel 252 to fit snugly within it. When the swing block 250 rotates, the second rotating wheel 252 rolls within the slot 241, causing the swing block 250 to slide along the lateral sliding plate 240. This ensures that the longitudinally sliding vertical sliding plate 210 can stably drive the two lateral sliding plates 240 to slide laterally.

[0042] In one embodiment, the angle between the lines connecting the first rotating wheel 251 and the second rotating wheel 252 to the rotation center of the swing block 250 is a right angle.

[0043] Specifically, the line connecting the rotation center of the first rotating wheel 251 and the rotation center of the swing block 250 is defined as the first line, and the line connecting the rotation center of the second rotating wheel 252 and the rotation center of the swing block 250 is defined as the second line. The first and second lines intersect at the rotation center of the swing block 250, therefore the angle between the first and second lines is a right angle. This ensures that the longitudinally sliding vertical slide plate 210 drives the two lateral slide plates 240 to slide laterally.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, a first limiting block 281 is provided on the substrate 100, and a second limiting block 282 is provided on the longitudinal sliding plate 210. A limiting post 283 is provided on the side of the first limiting block 281 near the second limiting block 282, and the limiting post 283 passes through the second limiting block 282. An elastic member 220 is sleeved on the limiting post 283 so that the elastic member 220 abuts against the first limiting block 281 and the second limiting block 282 respectively.

[0045] It should be noted that, in order to ensure that the elastic element 220 can stably push the longitudinal sliding plate 210 to slide, a first limiting block 281 is installed on the base plate 100, and a second limiting block 282 is installed on the longitudinal sliding plate 210. Then, one end of the limiting post 283 is fixedly installed on the first limiting block 281, so that the other end of the limiting post 283 passes through the second limiting block 282. The elastic element 220 is sleeved on the limiting post 283, so that the elastic element 220 abuts against the first limiting block 281 and the second limiting block 282 respectively. In one embodiment, the elastic element 220 is a spring.

[0046] like Figure 4 and Figure 5 As shown, in one embodiment, the limiting post 283 has a pressure regulating groove 2831 along the axial direction. The cylindrical ceramic clamping structure 10 also includes a pressure regulating component 300. The pressure regulating component 300 includes a pressure regulating ring 310, a pressure regulating rod 320, a pressure sensor 330, and a top pressure block 340. The pressure regulating rod 320 passes through the pressure regulating groove 2831. The pressure regulating ring 310 is rotatably mounted on the first limiting block 281 and is screwed to the pressure regulating rod 320. The pressure sensor 330 is mounted on the end of the pressure regulating rod 320 away from the pressure regulating ring 310. The top pressure block 340 is mounted on the pressure sensor 330 and abuts against the elastic member 220.

[0047] It should be noted that the aforementioned pressure regulating assembly 300 is provided to apply different clamping forces to cylindrical ceramics of different diameters. Specifically, a pressure regulating groove 2831 is formed in the axial direction of the limiting post 283, allowing the pressure regulating rod 320 to pass through the groove. The pressure regulating ring 310 is rotatably mounted on the first limiting block 281, for example, by means of a bearing, allowing it to rotate relative to the first limiting block 281. Furthermore, the pressure regulating ring 310 and the pressure regulating rod 320 are screwed together, so that rotating the pressure regulating ring 310 causes the pressure regulating rod 320 to slide within the pressure regulating groove 2831. Further, a pressure sensor 330 is mounted on one end of the pressure regulating rod 320, and a top pressure block 340 is mounted on the test end of the pressure sensor 330, abutting against the elastic member 220. Thus, by rotating the pressure regulating ring 310, the pressure regulating rod 320 drives the top pressure block 340 to slide relative to the limiting post 283 via the pressure sensor 330. This causes the top pressure block 340 to push against the elastic member 220, at which point the elastic member 220 abuts against both the top pressure block 340 and the second limiting block 282. By rotating the pressure regulating ring 310, the compression amount of the elastic member 220 can be adjusted, thereby adjusting the elastic thrust exerted on the second limiting block 282 by the elastic member 220, which in turn adjusts the clamping force between the two clamping members 260 used to hold the cylindrical ceramic. Therefore, different clamping forces can be applied to cylindrical ceramics of different diameters.

[0048] like Figure 5 As shown, in one embodiment, the top pressure block 340 includes a top pressure body 341 and a plurality of extension rods 342. The top pressure body 341 is disposed on the pressure sensor 330, and each extension rod 342 is disposed on the outer peripheral wall of the top pressure body 341. Each extension rod 342 extends from the pressure regulating groove 2831 to the outside of the limiting post 283, so that each extension rod 342 abuts against the elastic member 220.

[0049] It should be noted that, in order for the pressing block 340 to stably push the elastic member 220, the pressing block 340 is configured as a combination of a pressing body 341 and each extension rod 342. Specifically, each extension rod 342 is located on the outer peripheral wall of the pressing body 341, wherein the pressing body 341 is located within the pressure regulating groove 2831, and each extension rod 342 extends from the pressure regulating groove 2831 to the outside of the limiting post 283, so that each extension rod 342 jointly pushes the elastic member 220. In one embodiment, the pressing body 341 and each extension rod 342 are integrally formed. In one embodiment, four extension rods 342 are provided, and the four extension rods 342 are equally angled on the outer outer wall of the pressing body 341.

[0050] like Figure 1 and Figure 3As shown, in one embodiment, the clamping member 260 includes a base block 261, a clamping block 262 and an elastic part. The base block 261 is disposed on the lateral sliding plate 240, and the elastic part is connected to the base block 261 and the clamping block 262 respectively. The clamping block 262 is used to clamp the cylindrical ceramic.

[0051] It should be noted that the base block 261 is mounted on the lateral sliding plate 240, and the clamping block 262 is mounted on the base block 261 via an elastic part, so that the clamping block 262 has a certain buffer distance relative to the base block 261. For example, the elastic part is elastic rubber, or more specifically, it can be a spring. In this way, when the clamping block 262 contacts the outer wall of the cylindrical ceramic, the elastic part can prevent the clamping block 262 from making hard contact with the cylindrical ceramic, and can further prevent the clamping block 262 from scratching the surface of the cylindrical ceramic.

[0052] Furthermore, such as Figure 1 and Figure 3 As shown, in one embodiment, a V-groove 2621 is also provided on the side of the clamping block 262 away from the base block 261. In this way, the V-groove 2621 can ensure that the clamping block 262 stably clamps and fixes the cylindrical ceramic.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
