Description

Technical Field

[0001] This utility model relates to the field of shim clamping technology, specifically to a clamping tool for processing adjusting shims. Background Technology

[0002] In the gasket manufacturing process, the transfer step after gasket processing is crucial, and finger pneumatic clamps are a commonly used key piece of equipment in this step. Their technological development and application have a direct impact on production efficiency and product quality.

[0003] Currently, the transfer of gaskets after processing typically employs finger-operated pneumatic grippers. When using these grippers, gas is introduced into the inner cavity, and a piston rod within the cavity moves the gasket downwards or upwards. This causes two semi-cam blocks to rotate within the gripper's housing, leading to the two T-blocks moving closer together or separating. The T-blocks are then secured to the L-block with bolts, allowing the T-blocks to carry the L-blocks closer together or separate. The gripper at the bottom of the L-block clamps the gasket, and the transfer is then accomplished by rotating a support or other equipment that drives the finger-operated pneumatic gripper.

[0004] Although the above equipment can clamp the adjusting shims using the clamps on the bottom of the L-block, the piston rod inside the cavity pushes the shims downwards or upwards, resulting in a short movement distance for the two half-cam blocks to drive the two T-blocks respectively. While the L-block is bolted to the T-block, the clamps below the L-block can only clamp shims from the same batch. If the shims are from the same batch, the L-block needs to be removed from the T-block, and a clamp suitable for this batch of L-blocks needs to be replaced. This process is cumbersome and troublesome. Utility Model Content

[0005] In view of this, the present invention provides a fixture for processing adjustment shims. The present invention allows right-angle clamping blocks to move within the adjustment groove, thereby adjusting the spacing between the right-angle clamping blocks. This accommodates different sizes of spacing to clamp the outer arc surface of the adjustment shim, thereby reducing the need for personnel to replace L-blocks and facilitating transfer during subsequent processing.

[0006] To solve the above-mentioned technical problems, this utility model provides a fixture for processing shims, including a fixture housing, a pneumatic clamping assembly inside the fixture housing, and a fixing plate on the bottom of the fixture housing. A sliding groove is provided on the bottom of the fixing plate, and two T-shaped blocks are slidably disposed within the sliding groove. L-blocks are bolted to the sides of the two T-blocks, and adjusting components are provided on the L-blocks. The adjusting components also include adjusting grooves on the L-blocks, and right-angle clamping blocks are slidably disposed within each adjusting groove. First, the fixture housing is mounted on a rotating bracket. Then, the operator adjusts the right-angle clamping blocks in the adjusting grooves of the L-blocks according to the diameter of the shim, thus facilitating the clamping of shims of different sizes. Then, the pneumatic clamping assembly drives the two T-blocks, causing them to move closer or further apart, facilitating the movement of the L-blocks and right-angle clamping blocks, thereby clamping the shims and facilitating their transfer during subsequent processing.

[0007] The pneumatic clamping assembly also includes a rectangular groove disposed within the clamp housing. Two rotating rods are rotatably disposed within the rectangular groove. Half-cam block one and half-cam block two are respectively disposed on the two rotating rods. Fixed block one is disposed on the side end of half-cam block one, and fixed block two is disposed on the side end of half-cam block two. Fixed block one is located at the side end of fixed block two. This provides support for half-cam block one and half-cam block two, while facilitating their rotation.

[0008] The pneumatic clamping assembly also includes notches one and two respectively provided on the slide groove, and notches three and four respectively provided on the top of the two T-blocks. Half-cam block one passes through notch one, and the tail end of half-cam block one is located inside notch three. Half-cam block two passes through notch two, and the tail end of half-cam block two is located inside notch four. That is, half-cam block one is engaged with notch three on the T-block, so that half-cam block one can drive the T-block to move, and half-cam block two can also drive the other T-block to move.

[0009] The pneumatic clamping assembly also includes a circular groove inside the clamp housing, located at the top of a rectangular groove. A hydraulic telescopic rod is fixedly installed inside the circular groove. Two semicircular blocks are fixedly installed on the output shaft of the hydraulic telescopic rod. Both the first and second fixed blocks have strip-shaped holes. The inner sides of the two semicircular blocks are located at the side ends of the first and second fixed blocks, respectively. A hinge rod is installed between the two semicircular blocks, passing through the strip-shaped holes. That is, when the output shaft of the hydraulic telescopic rod extends or retracts, the hinge rod between the two semicircular blocks moves within the first and second fixed blocks, thereby enabling the hydraulic telescopic rod to drive the first and second fixed blocks.

[0010] The adjusting component also includes a threaded rod set in the adjusting groove, and the threaded rod is threaded with the internal threads of the right-angle clamping block; that is, the threaded rod can drive the right-angle clamping block to move, thereby facilitating the adjustment of the position of the right-angle clamping block.

[0011] The adjusting component also includes drive buttons that are all located on the side of the L-block. The drive buttons are connected to one end of the threaded rod; that is, the drive buttons make it easy for personnel to drive the threaded rod to rotate.

[0012] The adjusting component also includes arc-shaped grooves that are all set on the right-angle clamping blocks; that is, arc-shaped grooves to facilitate the clamping of the shims.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. First, drive the threaded rod with the drive button, which will move the right-angle clamping block. This allows the right-angle clamping block to slide in the adjustment groove, which indirectly facilitates the adjustment by the operator and allows the distance between the two right-angle clamping blocks to be adjusted.

[0015] 2. The output shaft of the hydraulic telescopic rod drives the two semicircular blocks to move down or up, causing fixed block one and fixed block two to rotate alternately. This indirectly drives half cam block one and half cam block two to rotate. During the rotation, half cam block one and half cam block two can carry two T-shaped blocks to move in the slide groove on the fixed plate, which indirectly allows the right-angle clamping blocks on the side ends of the two T-shaped blocks to quickly clamp the gasket.

The fixture housing 100 is used to mount on a rotating arm to facilitate the transfer of the shims. A pneumatic clamping assembly is provided inside the fixture housing. The pneumatic clamping assembly also includes a fixing plate 200 disposed on the bottom of the fixture housing. The fixing plate 200 is fixedly mounted on the bottom of the fixture housing by welding, and the fixture housing provides support for the fixing plate 200. A sliding groove 218 is provided on the bottom of the fixing plate 200. Two T-shaped blocks 201 are slidably disposed in the sliding groove 218. Driven by the pneumatic fixture assembly, the pneumatic fixture assembly... The two T-shaped blocks 201 can move away from each other or closer to each other within the slide groove 218. The side ends of the two T-shaped blocks 201 are bolted with L-blocks 202. The L-blocks 202 are equipped with adjusting components, including adjusting grooves 303 on the L-blocks 202. Right-angle clamping blocks 300 are slidably arranged in the adjusting grooves 303. The right-angle clamping blocks 300 can move on the adjusting grooves 303 to adjust the distance between the right-angle clamping blocks 300. This allows for clamping of the outer arc surface of the adjusting shim at different distances, thereby reducing the need for personnel to replace the L-blocks 202.

[0025] clamp housing 100 Figure 2 As shown,

[0026] The pneumatic clamping assembly also includes a rectangular groove 204 disposed in the clamp housing 100. Two rotating rods 211 are rotatably disposed in the rectangular groove 204. Half cam block 1 212 and half cam block 213 are respectively disposed on the two rotating rods 211. The two rotating rods 211 are installed in the rectangular groove 204, so that the half cam block 1 212 and half cam block 213 have small rotation and floating in the rectangular groove 204. A fixing block 1 210 is disposed on the side end of half cam block 1 212, and a fixing block 209 is disposed on the side end of half cam block 213. The fixing block 1 210 is located on the side end of the fixing block 209.

[0027] The pneumatic clamping assembly also includes notches 214 and 215 respectively provided on the fixed plate 200, notches 216 and 217 respectively provided on the top of the two T-blocks 201, half cam block 212 passing through notch 214, the tail end of half cam block 212 located inside notch 3 216, half cam block 213 passing through notch 2 215, notches 214 and 215 reserve a certain space for half cam block 212 and half cam block 213, the tail end of half cam block 213 located inside notch 4 217, half cam block 212 and half cam block 213 respectively engaging in notches 3 216 and notch 4 217, so that half cam block 212 and half cam block 213 can carry the T-block 201 to move;

[0028] The pneumatic clamping assembly also includes a circular groove 205 provided inside the clamp housing 100. The circular groove 205 is located at the top of the rectangular groove 204. A hydraulic telescopic rod 206 is fixedly installed inside the circular groove 205. A fixing plate is added to the cylinder end of the hydraulic telescopic rod 206, and then it is fixed to the side end of the clamp housing 100 by bolts. Two semi-circular blocks 203 are fixedly installed on the output shaft of the hydraulic telescopic rod 206. The two semi-circular blocks 203 are fixed to the hydraulic telescopic rod 206 by welding. On the output shaft, there is a certain distance between the two semicircular blocks 203. Both the first fixed block 210 and the second fixed block 209 are provided with strip holes 208. The inner sides of the two semicircular blocks 203 are located at the side ends of the first fixed block 210 and the second fixed block 209, respectively. A hinge rod 207 is provided between the two semicircular blocks 203. The hinge rod 207 passes through the strip hole 208. The hinge rod 207 enters the strip hole 208, so the range of motion of the hinge rod 207 in the strip hole 208 is small.

[0029] Because there is a hinge rod 207 between the two semicircular blocks 203, but the hinge rod 207 is inside the strip hole 208 on the first fixed block 210 and the second fixed block 209, the output shaft of the hydraulic telescopic rod 206 drives the two semicircular blocks 203 to move down or up, causing the first fixed block 210 and the second fixed block 209 to rotate alternately, which indirectly drives the first half cam block 212 and the second half cam block 213 to rotate. However, during the rotation, the first half cam block 212 passes through the fixed block 209. The notch 214 on plate 200, and the end of half cam block 212 is engaged in notch 216 of T-block 201. Secondly, half cam block 213 passes through notch 215, and the end of half cam block 213 is engaged in notch 217 of T-block 201. This allows the two T-blocks 201 to move a short distance in the slide groove 218 on the fixed plate 200, and indirectly allows the right angle clamping blocks 300 on the side ends of the two T-blocks 201 to quickly clamp the gasket.

[0030] Adjustment groove 303, such as Figure 3 As shown,

[0031] The adjusting component also includes a threaded rod 302 disposed in the adjusting groove 303, and the threaded rod 302 is threaded with the internal thread of the right-angle clamping block 300;

[0032] The adjusting component also includes drive buttons 301, which are all located on the side of the L block 202. The drive buttons 301 are connected to one end of the threaded rod 302.

[0033] Because the external thread of the threaded rod 302 is threaded with the internal thread of the right-angle clamping block 300, the rotation of the drive button 301 can drive the threaded rod 302 to move the right-angle clamping block 300, allowing the right-angle clamping block 300 to slide in the adjustment groove 303, which indirectly facilitates the personnel to freely adjust the spacing of the right-angle clamping block 300.
