Description

Technical Field

[0001] This invention relates to the field of clamping device technology, and more specifically, to a clamping device suitable for various irregularly shaped parts. Background Technology

[0002] Clamping devices, as key equipment in industrial production, play a crucial role in providing stable positioning and constraint for irregularly shaped parts. In machining processes, they counteract external forces generated by cutting, drilling, and other operations, preventing part misalignment (within ±0.05mm control accuracy) and ensuring that machining dimensions meet design requirements. In assembly scenarios, they precisely fix the position of parts, ensuring hole alignment and interface fit, thus improving assembly efficiency. In industrial settings such as machining and assembly, it is often necessary to stably clamp various irregularly shaped parts (such as parts with curved surfaces, recesses, protrusions, or other irregular structures).

[0003] Regarding the aforementioned technologies, existing clamping devices mostly employ a single rigid structure (such as chucks or jaws), with a fixed clamping surface that can only accommodate irregularly shaped parts of specific sizes or simple contours. When faced with irregularly shaped parts with large curvature variations and complex structures, rigid clamping is prone to problems with loose fit. Some irregularly shaped parts have dedicated fixtures, but customizing special fixtures for different irregularly shaped parts requires frequent equipment changes, increasing production costs (fixture costs account for 20% to 40% of the total equipment investment), making it difficult to meet the production needs of multiple varieties and small batches. Therefore, a clamping device suitable for different irregularly shaped parts is proposed. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a clamping device suitable for various irregularly shaped parts, employing the following technical solution:

The main module includes a fixed platform with a long slot and two movable slots on its top. The irregularly shaped clamping module includes a movable component disposed between the front and rear faces of the inner wall of the fixed platform. Two irregularly shaped clamping components are disposed on the movable component. A first bidirectional screw is rotatably connected between the two sides of the inner wall of the long slot. Two movable components are slidably connected inside the long slot. Both movable components are threadedly connected to the outer surface of the first bidirectional screw.

[0009] Furthermore, the connecting plate is provided with two fixing bolts, and the connecting plate is connected to the vise by the two fixing bolts. The first mounting bolt is adapted to the top of the connecting plate and the vise.

[0010] Furthermore, the movable component includes a movable seat slidably connected inside the long groove. The movable seat is threadedly connected to a first bidirectional screw.

[0015] In summary, the present invention has the following beneficial technical effects:

[0016] (1) The present invention, through the setting of irregular clamping components, moving components, airbags, locking components, linkage components and control components, enables the structure to fix the small curvature reference surface by rigid clamping, and the airbags fill the gaps in the large curvature area to form a rigid-flexible co-constraint. The rigidity ensures the overall positioning stability of the part and resists the processing load, while the airbags flexibly wrap the irregular surface. The four rows of airbags balance the force system and adapt to a variety of irregular parts. There is no need to frequently change the clamps, which improves the versatility of the clamping device and effectively solves the problem of poor compatibility of pure rigid clamping with easily damaged parts.

[0017] (2) The present invention, through the setting of vise, connecting plate and fixing bolt, allows the irregular clamping component to be installed on vise for use. Without modifying existing equipment, the clamping capacity of vise for irregular parts can be expanded, reducing the equipment upgrade cost of enterprises and significantly improving the scenario applicability and functionality of the device.

[0018] (3) By setting up a metal throttle, magnetic block, torsion groove and connecting slider, the present invention can first control both airbags to contact the irregular part, and then operate to clamp it. Distance compensation can be made to avoid the two airbags contacting the irregular part at different times to clamp it, which would affect the clamping effect. The control of both contact and clamping steps is completed by the metal throttle, which improves the overall ease of operation.

[0019] (4) The present invention, through the setting of connector, inflation nozzle, kit block and threaded pin, allows the connector and inflation nozzle to be separated after the nut and threaded pin are removed, thereby facilitating the disassembly and replacement of the airbag. In this way, different specifications of airbags can be replaced according to the different shaped parts with large differences, or the airbag can be quickly replaced after wear, further improving the device's adaptability to various shaped parts.

[0036] The following is in conjunction with the appendix Figure 1 - Figure 9 The present invention will be described in further detail below.

[0037] Please see Figure 1 - Figure 9 A clamping device suitable for various irregularly shaped parts includes a main module 100, an irregularly shaped clamping module 200, a vise 300, and a connecting plate 400. The main module 100 includes a fixed platform 110, the top of which has an elongated slot 130 and two movable slots 120. The irregularly shaped clamping module 200 includes a movable component 210 disposed between the front and rear faces of the inner wall of the fixed platform 110, and two irregularly shaped clamping components 220 are disposed on the movable component 210. A first bidirectional screw 230 is rotatably connected between the two sides of the inner wall of the elongated slot 130. The internal sliding connection has two movable components 240, both of which are threaded to the outer surface of the first bidirectional screw 230. Each of the two movable components 240 is provided with an airbag 250, which is rectangularly distributed with the two irregular clamping components 220. Each of the two movable components 240 is provided with a locking component 260. A linkage component 270 is provided between the inside of the long groove 130 and the two locking components 260. One end of the first bidirectional screw 230 is provided with a control component 280, which is connected to the linkage component 270.

[0038] In use, the irregularly shaped part to be fixed is placed on top of the fixing platform 110, with the part positioned between the two airbags 250 and the two irregularly shaped clamping components 220. The two surfaces of the irregularly shaped part with relatively small curvature face the two irregularly shaped clamping components 220 respectively. The operator first operates the moving component 210, which drives the two irregularly shaped clamping components 220 to rigidly clamp the two surfaces of the irregularly shaped part with small curvature. After clamping, the operator then drives the first bidirectional screw 230 by the control component 280. The first bidirectional screw 230 drives the two movable components 240. At this time, the two airbags 250 are fully inflated, and the two movable components 240 drive the two airbags 250 to contact the other two surfaces of the irregularly shaped part one after the other. When both airbags 250 contact the irregularly shaped part on a surface with a large curvature, the control component 280 drives the linkage component 270, which in turn drives two locking components 260. The two locking components 260 lock the two movable components 240 respectively. After locking, the operator continues to rotate the control component 280 to drive the first bidirectional screw 230. The first bidirectional screw 230 continues to drive the two airbags 250 closer, thereby increasing the clamping force of the two airbags 250 on the irregularly shaped part, ensuring the clamping effect, and maintaining the stability of the irregularly shaped part. Through the clamping of the two airbags 250, they can better fit with the outer surface of the irregularly shaped part, enabling this clamping device to clamp more types of irregularly shaped parts and ensure the clamping effect.

[0039] The irregular clamping assembly 220 includes a mounting base 221. Two first mounting bolts 222 are provided on the mounting base 221. A first arc-shaped plate 223 is movably connected inside the mounting base 221. Two first arc-shaped grooves 224 are formed on the top of the mounting base 221. Two first limiting bolts 225 are movably connected inside the two first arc-shaped grooves 224. Both first limiting bolts 225 are threadedly connected to the first arc-shaped plate 223. A second arc-shaped plate 226 is provided on the top of the first arc-shaped plate 223. Two second mounting bolts 227 are threadedly connected between the second arc-shaped plate 226 and the first arc-shaped plate 223. The first arc-shaped plate 223 is movably connected to... The irregular clamping assembly 220 also includes two second arc-shaped grooves 229, each formed on a second arc-shaped plate 226. Each of the two second arc-shaped grooves 229 is movably connected to a second limiting bolt 2210, which is threadedly connected to the third arc-shaped plate 228. Each of the two third arc-shaped plates 228 is movably connected to a clamping block 2212. Two fourth arc-shaped plates 2211 are movably connected to the second arc-shaped plate 226. Each of the two fourth arc-shaped plates 2211 has a third arc-shaped groove 2213, and each of the two third arc-shaped grooves 2213 is movably connected to a third limiting bolt 2214. The four... The third limiting bolt 2214 is threadedly connected to each of the four clamping blocks 2212. The two fourth arc-shaped plates 2211 and the two third arc-shaped plates 228 are each threadedly connected to a third mounting bolt 2215. Bearings are mounted on the outer surfaces of the first limiting bolt 225, the second limiting bolt 2210, and the third limiting bolt 2214. These bearings are movably connected to the interiors of the first arc-shaped groove 224, the second arc-shaped groove 229, and the third arc-shaped groove 2213, respectively. The two first arc-shaped grooves 224 are concentric with the first arc-shaped plate 223, the two second arc-shaped grooves 229 are concentric with the third arc-shaped plate 228, and the two third arc-shaped grooves 2213 are concentric with the clamping blocks 2212. The holding block 2212 is in a concentric state. The moving component 210 includes a second bidirectional screw 211 rotatably connected between the front end face and the rear end face of the inner wall of the fixed platform 110. One end of the second bidirectional screw 211 extends to the outside of the fixed platform 110 and is fixedly connected to a control handle 214. Two limiting slide rods 212 are fixedly connected between the front end face and the rear end face of the inner wall of the fixed platform 110. Two moving seats 213 are slidably connected between the outer surfaces of the two limiting slide rods 212. Both moving seats 213 are threadedly connected to the outer surface of the second bidirectional screw 211. The mounting seat 221 is threadedly connected to the moving seat 213 by two first mounting bolts 222.

[0040] First, operate the rotary control handle 214. The rotary control handle 214 will drive the second bidirectional screw 211 to rotate. The rotation of the second bidirectional screw 211 will drive the two moving seats 213 to move closer to each other, so that the four clamping blocks 2212 contact the irregular part. The two third arc plates 228 will move, and the fourth arc plate 2211 will also be driven to move. At the same time, the first arc plate 223 will also move. Meanwhile, the first limiting bolt 225 moves inside the first arc groove 224, and the second limiting bolt 2210 moves inside the second arc groove 229. This allows the four clamping blocks 2212 to adapt to different angles, which facilitates the rigid clamping of the two small curvature surfaces of the irregular part. Furthermore, the irregular clamping assembly 220 is modularly designed, making it easier to manufacture.

[0041] The connecting plate 400 is provided with two fixing bolts 500. The connecting plate 400 is connected to the vise 300 by the two fixing bolts 500. The first mounting bolt 222 is adapted to the top of the connecting plate 400 and the vise 300.

[0042] The vise 300 is a common vise 300 available on the market. There are various types of vises 300 available on the market. The irregular clamping component 220 can be installed on the vise 300 for use through the connecting plate 400 and fixing bolts 500. The overall disassembly and disassembly operation is convenient, which enhances the functionality of this clamping device. The vise 300's clamping capacity for irregular parts can be expanded without modifying existing equipment, reducing the cost of equipment upgrades for enterprises and significantly improving the device's applicability and functionality in various scenarios.

[0043] The movable component 240 includes a movable seat 241 slidably connected inside the elongated slot 130. The movable seat 241 is threadedly connected to the first bidirectional screw 230. A movable rod 242 is movably connected inside the movable seat 241. A fitting block 243 is sleeved on one end of the movable rod 242. A threaded pin 246 is movably inserted between the fitting block 243 and the interior of the movable rod 242. Two nuts 245 are threadedly connected to the outer surface of the threaded pin 246. An airbag seat 244 is fixedly connected to one side of the fitting block 243, and an airbag 250 is disposed in the airbag seat. Inside 244, an inflation nozzle 247 is connected to the airbag 250, and the inflation nozzle 247 extends to the outside of the airbag seat 244. An air pump 248 is provided on the movable seat 241, and a hose is connected to the output end of the air pump 248. One end of the hose is connected to a connector 249, which is connected to the inflation nozzle 247. The movable component 240 also includes a metal block 2411 fixedly connected to the other end of the movable rod 242. Two blocking blocks 2410 are fixedly connected to the top of the fixed platform 110, and the two blocking blocks 2410 are in contact with the airbag seat 244.

[0044] Reverse rotation of the first bidirectional screw 230 can drive the movable seat 241 to reset. The two blocking blocks 2410 will block the airbag seat 244, so that the airbag 250 resets to the same position each time. By removing the nut 245 and the threaded pin 246, and then separating the connector 249 and the inflation nozzle 247, the airbag 250 can be disassembled and replaced. This allows the airbag 250 to be replaced when damaged, or to be replaced with an airbag 250 of a different size for use.

[0045] The locking assembly 260 includes a horizontal plate 262 fixedly connected inside the movable seat 241. A locking rod 263 is movably connected inside the horizontal plate 262. A long locking groove 261 is formed at the bottom of the movable rod 242. A first spring 264 is fixedly connected between the outer surface of the locking rod 263 and the bottom of the horizontal plate 262. A compensating latch 267 is movably connected to the top of the locking rod 263. A compensating spring is fixedly connected between the bottom end of the compensating latch 267 and the locking rod 263. A rolling column 266 is rotatably connected between the two sides of the inner wall of the movable seat 241. A groove is formed on the outer surface of the rolling column 266. A ball bearing 265 is movably connected to the bottom end of the locking rod 263. The ball bearing 265 contacts the inner wall of the groove. The linkage assembly 270 includes a hexagonal rod 271 rotatably connected between the two sides of the inner wall of the long groove 130. The hexagonal rod 271 passes through the rolling column 266. A cylindrical rod 272 is fixedly connected to one end of the hexagonal rod 271. The rod 272 extends to the outside of the fixed platform 110. The outer surface of the cylindrical rod 272 is provided with a torsion groove 273. The control component 280 includes a rectangular groove 281 opened at one end of the first bidirectional screw 230. A metal handle 282 is movably connected inside the rectangular groove 281. A second spring 283 is fixedly connected between one end of the metal handle 282 and the inner wall of the rectangular groove 281. A magnetic block 284 adapted to the metal handle 282 is fixedly connected to one end of the inner wall of the rectangular groove 281. A cylindrical block 285 is fixedly connected to the outer surface of the metal handle 282. A mounting plate 286 is rotatably fitted on the outer surface of the cylindrical block 285. A connecting slider 287 is fixedly connected to the inner wall of the mounting plate 286. The connecting slider 287 is movably connected inside the torsion groove 273. Two directional sliders 288 are fixedly connected to one side of the mounting plate 286. One end of each of the two directional sliders 288 extends into the interior of the fixed platform 110.

[0046] Operating the rotating metal handle 282 causes the cylindrical block 285 to rotate inside the mounting plate 286. Simultaneously, the metal handle 282 drives the first bidirectional screw 230 to rotate. At this time, the first bidirectional screw 230 drives the two movable seats 241 to move closer together. The air pump 248 then inflates the airbags 250. The two movable seats 241 will cause the two airbags 250 to successively contact the other two surfaces with larger curvatures of the irregular part. The airbag 250 that contacts the irregular part first will stop moving. The movable seats 241 move on the outer surface of the movable rod 242. When both airbags 250 are in contact with the irregular part, pressing the metal handle 282 will compress the second spring 283. Simultaneously, the metal handle 282 will magnetically connect with the magnetic block 284, and the cylindrical block 285 will drive the mounting plate 286 to move. The directional slide rod 288 moves towards the interior of the fixed platform 110. The connecting slider 287 will slide inside the torsion groove 273. At this time, the torsion groove 273 drives the cylindrical rod 272 and the hexagonal rod 271 to rotate. The hexagonal rod 271 drives the rolling column 266 to rotate. At this time, the ball 265 rolls out of the groove, causing the locking rod 263 to rise and the compensating lever 267 to connect with the long locking groove 261. Then, the operator continues to rotate the metal handle 282 to drive the first bidirectional screw 230. The first bidirectional screw 230 continues to drive the two movable seats 241 to move closer. Since the compensating lever 267 is connected with the long locking groove 261, the compensating lever 267 pushes the movable rod 242. The movable rod 242 applies pressure to the airbag 250, thereby gradually increasing the clamping force of the two airbags 250 on the irregular part, so that the airbags 250 can better wrap the large curvature surface of the irregular part, ensuring the clamping effect and maintaining the stability of the irregular part.

[0047] The implementation principle of this invention is as follows: In use, the irregularly shaped part to be fixed is placed on the top of the fixing platform 110, and the irregularly shaped part is located between the two airbags 250 and the two irregularly shaped clamping components 220. The two sides of the irregularly shaped part with relatively small curvature face the two irregularly shaped clamping components 220 respectively. The operator first operates the rotating control handle 214, which drives the second bidirectional screw 211 to rotate. The rotation of the second bidirectional screw 211 drives the two moving seats 213 to move closer to each other, so that the four clamping blocks 2212 contact the irregularly shaped part. The two third arc plates 228 will move, and the fourth arc plate 2211 will also be driven to move. At the same time, the first arc plate 223 also moves. Meanwhile, the first limiting bolt 225... The first arc-shaped groove 224 moves within the first, and the second limiting bolt 2210 moves within the second arc-shaped groove 229, allowing the four clamping blocks 2212 to adapt to different angles. This facilitates rigid clamping of the two small curvature surfaces of the irregularly shaped part. After clamping, the operator operates the rotating metal handle 282, causing the cylindrical block 285 to rotate inside the mounting plate 286. Simultaneously, the metal handle 282 drives the first bidirectional screw 230 to rotate. At this time, the first bidirectional screw 230 drives the two movable seats 241 to move closer to each other. At this point, the air pump 248 inflates the airbag 250. The two movable seats 241 will then drive the two airbags 250 to contact the other two surfaces with larger curvatures of the irregularly shaped part one after another. The airbag 250 that contacts the irregularly shaped part first will stop moving. When the movable seat 241 moves on the outer surface of the movable rod 242 and both airbags 250 are in contact with the irregular part, pressing the metal handle 282 will compress the second spring 283. At the same time, the metal handle 282 will be magnetically connected to the magnetic block 284, and the cylindrical block 285 will drive the mounting plate 286 to move. The directional slide rod 288 moves towards the inside of the fixed platform 110, and the connecting slider 287 will slide inside the torsion groove 273. At this time, the torsion groove 273 drives the cylindrical rod 272 and the hexagonal rod 271 to rotate. The hexagonal rod 271 drives the rolling column 266 to rotate. At this time, the ball 265 rolls out of the groove, causing the locking rod 263 to rise and the compensating latch 267 to connect with the long locking groove 261. After that, the operator continues to rotate the metal handle. The first bidirectional screw 230 is driven by drive 282. The first bidirectional screw 230 continues to drive the two movable seats 241 closer together. Since the compensating lever 267 is connected to the long locking groove 261, the compensating lever 267 pushes the movable rod 242. The movable rod 242 applies pressure to the airbag 250, thereby gradually increasing the clamping force of the two airbags 250 on the irregularly shaped part. This allows the airbags 250 to better wrap the large curvature surface of the irregularly shaped part, ensuring the clamping effect and maintaining the stability of the irregularly shaped part. Through the clamping of the two airbags 250, they can better fit the outer surface of the irregularly shaped part, enabling this clamping device to clamp more types of irregularly shaped parts while ensuring the clamping effect. During subsequent reset, the metal handle 282 is pulled outward to separate it from the magnetic block 284.This allows the compensation lever 267 to separate from the long locking groove 261. Reverse rotation of the first bidirectional screw 230 resets the movable seat 241. The two blocking blocks 2410 will block the airbag seat 244, ensuring the airbag 250 returns to the same position each time. Removing the nut 245 and threaded pin 246, and then separating the connector 249 and inflation nozzle 247, allows for the disassembly and replacement of the airbag 250. This enables replacement of the airbag 250 when damaged, or the use of airbags of different sizes. Furthermore, the irregularly shaped clamping assembly 220 can be mounted on the vise 300 via the connecting plate 400 and fixing bolts 500, thus enhancing the functionality of this clamping device.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
