The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0045] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention. Example

[0046] See also Figure 2-Figure 3 As shown, a hydraulic clamp for a rear suspension control arm includes a tooling base plate 1, on which a positioning mechanism for placing a product 2 is arranged, and the positioning mechanism includes a contour block 3 for abutting one end of the product 2, a clamping structure 4 for pushing the product 2 toward one side of the contour block 3, a clamping structure 5 for pressing the product 2 from top to bottom, a supporting structure 6 for supporting the product 2 from bottom to top, and an anti-fool structure 7 distributed on both sides of the product 2.

[0047] In this embodiment, two sets of positioning mechanisms 3 are arranged on the tooling base plate 1, and both sets of positioning mechanisms 3 can place one product 2, and the two sets of positioning mechanisms 3 share one set of clamping structures 4. That is, one set of clamping structures 4 can drive the two sets of positioning mechanisms individually or simultaneously to achieve product positioning.

[0048] Specifically, combined Figure 4As shown, the clamping structure 4 includes a cylinder seat 401, and slide seats 402 and 403 are arranged on both sides of the cylinder seat 401. Each slide seat 402 and 403 is provided with a slide groove 404, and a clamping block 405 is arranged in each slide groove 404, wherein one end of the clamping block 405 is exposed outside the corresponding slide seat 402 and 403 and has a V-shaped groove adapted to the product 2 on the side facing the product; the other end of the clamping block 405 is connected to one end of the push rod 406, and the other end of the push rod 406 is exposed outside the corresponding slide seat 402 and 403. A cover plate 407 covering the slide groove is arranged on each slide seat 402 and 403, and the cover plate 407 is locked on the slide seat by bolts. At the same time, a pad 408 for limiting the sliding of the push rod is provided on each slide seat 402, 403; the pad 408 is fixed to the corresponding slide seat by bolts, and a through hole is provided on the pad 408 for the push rod 406 to pass through. Through the above structure, pushing the push rod 406 to move can drive the pressing block 405 to move forward and backward.

[0049] The oil cylinder seat 401 in this embodiment adopts a double-head oil cylinder seat with two independent pistons. In order to enable the oil cylinder seat 401 to push the clamping blocks 405 on both sides to move forward and backward, two hinge seats 410 are arranged on the cylinder body of the oil cylinder seat 401. The two hinge seats 410 have the same structure, and each hinge seat 410 is hinged to the middle position of a pull rod 409. The two sides of the pull rod 409 correspond to the push rod 406 and the piston respectively. An oil circuit connected to the oil cylinder seat 401 is arranged in the tooling bottom plate 1. The oil circuit forms an oil inlet and an oil outlet on the tooling bottom plate 1. By controlling the oil circuit, the piston on the oil cylinder seat 401 can be driven to move forward and backward.

[0050] When the cylinder seat 401 is started, the piston moves outward and can push one end of the corresponding pull rod 409 to tilt outward. At this time, the other end of the pull rod tilts toward the side of the push rod and pushes the push rod 406 to move toward the side of the product. Under the action of the clamping block 405 and the imitation block 3, the product is clamped and fixed in the horizontal direction.

[0051] When the product processing is completed, the cylinder seat 401 retracts the piston. At this time, the piston retracts and no longer supports the pull rod 409. The on-site personnel can easily move the clamping block 405 backward. At this time, the product is no longer squeezed in the horizontal direction. With the cooperation of the clamping structure 5, the product can be directly removed from the fixture.

[0052] In this embodiment, there are three types of clamping structures 5, namely, a single-point clamping assembly 51, a double-point clamping assembly 52, and a multi-directional clamping assembly 53.

There is a downward cylindrical pressing part at the other end of the clamping plate A512. When the piston of the clamping cylinder A511 extends outward, the cylindrical pressing part on the clamping plate A512 is pressed on the product 2. The single-point clamping assembly 51 of the above structure can realize the clamping operation of a single position of the product.

[0054] Combination Figure 6 As shown, the multi-directional clamping assembly 53 includes a clamping cylinder B531 arranged on the tooling base plate 1, the piston end of the clamping cylinder B531 is hinged to one end of the clamping plate B532 through a floating joint, and the other end of the clamping plate B532 has a clamping plate head 5321 bent outward. The clamping plate B532 is provided with a crimping portion 533 that is pressed to the upper end surface of the product 2. The middle of the clamping plate B532 is hinged to the upper end of the bracket B534, and the lower end of the bracket B534 is hinged to the cylinder body of the clamping cylinder B531 (the cylinder body has a protrusion that is hinged to the bracket B534 through a short shaft).

[0055] When in use, the clamping cylinder B531 is started, the piston of the clamping cylinder B531 extends outward, and the other end of the clamping plate B532 is pressed down. At this time, the inner wall of the clamping plate head 5321 contacts the side of the product 2, and the crimping part 533 is pressed on the upper end surface of the product 2, thereby achieving the effect of vertically limiting the product and restricting its swing.

[0056] Combination Figure 7 As shown, the double-point clamping assembly 52 includes a clamping cylinder C521 disposed on the tooling base plate 1, the piston end of the clamping cylinder C521 is connected to the middle of the clamping plate C522 through a floating joint, and both ends of the clamping plate C522 have a crimping portion that is pressed onto the product 2. In this embodiment, the double-point clamping assembly 52 is disposed between two products, and the two crimping portions on the clamping plate C522 act on the two products respectively, and can perform single-point clamping on the two products at the same time.

[0057] In this embodiment, the support structure 6 includes support blocks, which are respectively located at both ends of the product 2 , and positioning columns abutting against the bottom of the product 2 are provided on the support blocks.

[0058] The support structure 6 and the pressing structure 5 in this embodiment are used in conjunction with each other, one provides support for the product from bottom to top, and the other presses the product from top to bottom, thereby achieving positioning of the product in the vertical direction.

[0059] The foolproof structure 7 in this embodiment includes foolproof rods, the number of which is an even number, and every two foolproof rods form a group and are distributed on both sides of the same position of the product 2, and the height of the foolproof rods is higher than the height of the edge of the adjacent product 2.

Along the blowing direction of the air blowing pipe 9, vertical through holes are provided on the tooling bottom plate 1. The above-mentioned vertical through holes correspond to the through holes at the two ends of the product, and waste can be discharged from the vertical through holes during the processing. At the same time, the air blowing of the above-mentioned air blowing pipe 9 can help take away some heat, reduce the temperature, reduce the influence of thermal deformation on the processing accuracy, and also extend the service life of the tool.

[0061] In this embodiment, lifting ears 8 are provided on the tooling base plate 1 , and the lifting ears 8 are diagonally distributed at the four corners of the tooling base plate 1 , so as to facilitate the lifting and transportation of the entire rear suspension control arm hydraulic clamp.
