Description

Technical Field

[0001] The present invention relates to the technical field of metal thin-walled part fixtures, and in particular to a metal thin-walled part anti-deformation processing fixture. Background Art

[0002] The core challenge in designing fixtures for thin-walled metal parts is how to prevent deformation of the parts during the clamping process. Since thin-walled metal parts typically have low rigidity and thin walls, they can easily deform due to excessive or uneven clamping forces during the clamping process.

[0003] Prior art includes the invention with announcement number CN119238157B, which discloses a clamping device for CNC machining of micro-precision thin-walled metal structural parts. The patent adopts an outer cover body, and a lifting assembly platform is slidably installed inside the outer cover body. The bottom of the outer cover body is rotatably provided with an eddy current component, and the outer side of the bottom of the outer cover body is provided with a mounting foot. The outer cover body is fixed to the machine tool through the mounting foot and bolts. Several groups of clamping assemblies are arranged in the lifting assembly platform, and the several groups of clamping assemblies are evenly distributed in a circular shape. Each group of clamping assemblies passes through the outer cover body to clamp the workpiece, and the eddy current component clears the cutting chips on the clamping device. By setting a screw sleeve that can be detached from the groove shaft and rotated, all the clamping shafts are driven to clamp the structural parts. All the clamping shafts disperse the total clamping force, and the shock-absorbing rubber further prevents damage to the thin-walled structural parts, prevents the thin-walled structural parts from deformation, and realizes adaptive clamping of multiple contours.

[0004] In daily use, the inventors found that in the existing technology, thin-walled metal parts have thin walls and poor overall rigidity, and are easily deformed by clamping force or external force. Excessive clamping force will cause deformation of the thin-walled parts, especially near the clamping point, where dents or bends may appear. Moreover, during the clamping process, the contact points of the clamps will concentrate stress, resulting in excessive local stress in the thin-walled parts, thereby causing deformation. Especially in the case of uneven clamping, deformation or rupture problems are likely to occur. Summary of the Invention

The inner wall of the slide groove 207 is slidably connected to the slider 206, and the end of the slider 206 away from the connecting seat 1 is fixedly connected to the top block 208. Both ends of the top block 208 are provided with a connecting groove 213, and the inner wall of the connecting groove 213 is slidably connected to the connecting block 212. The side of the connecting block 212 away from the top block 208 is fixedly connected to the slide plate 209, and the surfaces of the two slide plates 209 close to each other are slidably connected to the sleeve plate 210. The plate 210 is connected to the connecting seat 1 by means of the connecting structure 3. A rotating shaft 202 is provided inside the connecting seat 1.

The second bevel gear 204 is meshed with the first bevel gear 203, and the screw 205 is threadedly connected to the slider 206. When it is necessary to fix the thin-walled metal part, first fix the sleeve plate 210 and the slide plate 209 to the top plate, pull the sleeve plate 210 to move, the sleeve plate 210 drives the slide plate 209 to move, the slide plate 209 drives the connecting block 212 to move, and then insert the connecting block 212 into the connecting groove 213 for fixing, thereby facilitating the connection between the sleeve plate 210 and the top plate, rotate the rotating shaft 202 to move, the rotating shaft 202 drives the first bevel gear 203 to rotate, and the first bevel gear 203 drives the second bevel gear 204 to rotate The second bevel gear 204 drives the screw 205 to rotate, the screw 205 slides on the inner wall of the slide groove 207, the screw 205 drives the slider 206 to move, the slider 206 drives the top plate to move, the top plate drives the slide plate 209 to move, and the slide plate 209 drives the sleeve plate 210 to move. When the sleeve plate 210 and the slide plate 209 move, the slide plate 209 slides on the inner wall of the sleeve plate 210. The top plate and the sleeve plate 210 fix the metal thin-walled part. The cross-section of the rotating shaft 202 is circular and the rotating shaft 202 is a stainless steel shaft. The stainless steel material can increase the service life of the rotating shaft 202 and prevent the rotating shaft 202 from rusting during use. The end of the rotating shaft 202 away from the first bevel gear 203 is fixedly connected to a plurality of handles 201, and the plurality of handles 201 are evenly distributed on the rotating shaft 202. When the rotating shaft 202 needs to be rotated, the handle 201 can be directly rotated, and the handle 201 drives the rotating shaft 202 to rotate. The handle 201 makes it more convenient to rotate the rotating shaft 202. The sleeve plate 210 and the side of the top block 208 away from the first bevel gear 203 are fixedly connected to a protective pad 211, which is a rubber pad. The protective pad 211 can protect the thin-walled metal parts and prevent wear and deformation caused by the top block 208 and the sleeve plate 210 fixing the thin-walled metal parts.

[0045] The effect achieved by the entire clamping structure 2 is that it not only changes the clamping method, but also increases the force points between the clamp and the metal thin-walled part, and can synchronously adjust the top block 208, so it is faster and safer when clamping the metal thin-walled part.

[0046] like Figures 5 to 7 As shown, the connecting structure 3 includes an auxiliary groove 32, which is opened on the connecting seat 1, and the inner wall of the auxiliary groove 32 is slidably connected to the sliding rod 33. The inner wall of the sleeve 210 is opened with a limiting groove 37, and the inner wall of the limiting groove 37 is slidably connected to the round rod 34. The round rod 34 is fixedly connected to the sliding rod 33, and the arc surface of the round rod 34 is fixedly connected to the gasket 35. The inner wall of the limiting groove 37 is opened with a card slot 36, and the card slot 36 is adapted to the gasket 35. When the sleeve plate 210 needs to be connected, the sleeve plate 210 is pulled to move, and the sleeve plate 210 drives the limiting groove 37 to move, and then the limiting groove 37 is aligned with the round rod 34, and then the limiting groove 37 is inserted into the round rod 34, and then the limiting groove 37 contracts the gasket 35. After moving to the appropriate position, the gasket 35 is reset and snapped into the slot 36 for fixation. When the sleeve plate 210 moves, it drives the round rod 34 to move, and the round rod 34 drives the sliding rod 33 to move.

The arc surface of the slip ring 42 is fixedly connected with a plurality of connecting rods 43. The connecting rod 43 is fixedly connected to the side of the connecting seat 1 with an insertion rod 44. The connecting seat 1 is provided with a plurality of sockets 45 on the side close to the insertion rod 44, and the insertion rod 44 is adapted to the sockets 45. When the clamping structure 2 needs to be adjusted, the slip ring 42 is pulled to move, and the slip ring 42 slides on the arc surface of the rotating shaft 202. The slip ring 42 drives the connecting rod 43 to move, and the connecting rod 43 drives the insertion rod 44 to move. The slip ring 42 drives the spring 46 to stretch, and then separates the insertion rod 44 from the socket 45. Then, the clamping structure 2 is quickly adjusted.

The slip ring 42 drives the connecting rod 43 to reset, and the connecting rod 43 drives the insertion rod 44 to be inserted into the appropriate socket 45 for fixation.

The arc surface of the rotating shaft 202 is fixedly connected to a plurality of positioning rods 41, which are evenly distributed on the rotating shaft 202. The slip ring 42 is slidably connected to the positioning rods 41. The positioning rods 41 can limit the slip ring 42, preventing the slip ring 42 from rotating during use, thereby improving the sliding stability of the slip ring 42.

When the rotating shaft 202 needs to be rotated, the handle 201 can be directly rotated, and the handle 201 drives the rotating shaft 202 to rotate. The handle 201 makes it more convenient to rotate the rotating shaft 202. The protective pad 211 can protect the metal thin-walled parts to avoid wear and deformation when the top block 208 and the sleeve plate 210 fix the metal thin-walled parts.
