The pushing block 52 is driven and connected to the pushing cylinder 58. The pushing cylinder 58 drives the pushing block 52 to move up and down, thereby driving the two pushing blocks 51 to move toward each other or in the opposite direction synchronously, so that the two pushing blocks 51 can synchronously push and position the end plates 6 on the two positioning grooves 12.

[0035] In one embodiment of the present invention, a first inclined surface is provided on both sides of the pushing block 52, a fixed block 53 is provided on the pushing block 51, and a second inclined surface 54 is provided on the fixed block 53.

[0042] Specifically, the air hole 48 is connected to the blowing and suction device through the air pipe, and high-pressure gas is blown into the cavity 42, thereby driving the clamping block 45 on the piston block 43 to extend out of the limit opening 44. The pressing slope 47 on the clamping block 45 presses the end of the end plate 6 into the positioning groove 12, thereby ensuring that the positioning of the end plate 6 in the length direction during processing will not be displaced, avoiding errors caused by the movement of the product during the processing, and making the processed features more accurate.

[0046] Specifically, the free end of the rod is connected to the inner wall of the positioning groove 12, and the positioning base surface is perpendicular to the reference surface 22, so that the reference blocks 31 of different sizes can be adjusted according to the sizes of different products, so that the tooling can clamp products of various specifications and sizes.

[0047] In one embodiment of the present utility model, an opening 33 is provided on the inner side wall of the positioning groove 12, a limiting plate 34 is provided at the free end of the guide rod 32, the guide rod 32 is passed through the opening 33, a spring 35 is provided on the guide rod 32, and a limiting ring is provided on the edge of the opening 33, so that the guide rod 32 cannot be separated from the opening 33. The cross-section of the guide rod 32 is a polygonal structure, and the reference block 31 with different thicknesses can be directly clamped on the guide rod 32 through the corresponding slot thereon, and clamped between the reference block 31 and the positioning groove 12 under the reaction force of the spring 35.

[0048] Specifically, the number of corresponding reference blocks 31 is increased according to the length of the end plate 6, and the reference block 31 is pulled to pull the guide rod 32 to compress the spring 35, so that a certain distance appears between the reference block 31 and the side wall of the positioning groove 12, which is used to increase or decrease the number of other reference blocks 31, so that the adjusted end face reference component 3 matches the end plate 6. According to the size of different products, the number of other reference blocks 31 can be increased or decreased, so that the tooling can clamp the same products of multiple lengths and sizes.

[0049] Usage process

[0050] Select a reference plate 21 of corresponding thickness according to the thickness specification of the end plate 6, increase the number of corresponding reference blocks 31 according to the length of the end plate 6, pull the reference block 31 to pull the guide rod 32 to compress the spring 35, so that a certain distance appears between the reference block 31 and the side wall of the positioning groove 12, which is used to increase or decrease the number of other reference blocks 31, so that the adjusted end face reference component 3 matches the end plate 6, and the two end plates 6 are placed in the two positioning grooves 12 respectively to ensure that the vertical positioning of the end plate 6 will not be displaced during processing.

[0051] The push cylinder 58 drives the push block 52 to move downward, so that the first inclined surface on the push block 52 slides on the second inclined surface 54. The push block 52 has a stepped structure with a larger upper portion and a smaller lower portion, which drives the two push blocks 51 to move horizontally in opposite directions synchronously until the two push blocks 51 respectively press against the side surfaces of the end plate 6, ensuring that the end plate 6 does not move in the width direction during processing.

[0052] The air hole 48 is connected to the blowing and suction device through the air pipe, and high-pressure gas is blown into the cavity 42, thereby driving the clamping block 45 on the piston block 43 to extend out of the limit opening 44. The pressing slope 47 on the clamping block 45 presses the end of the end plate 6 into the positioning groove 12, thereby ensuring that the positioning of the end plate 6 in the length direction will not be displaced during processing. After the three directions of the end plate 6 are firmly fixed by the above structure, the end plate 6 can be processed, effectively ensuring the processing accuracy.
