Description

Technical Field

[0001] The utility model relates to the field of clamping equipment, in particular to a clamp. Background Art

[0002] A clamp is a transfer device that can clamp a workpiece and transfer it to the next step for processing. The clamp used in forging processing refers to the clamping device for forging processing disclosed in application number: CN201920167210.8. The workpiece is clamped by two clamping plates mounted on a mounting seat that can reciprocate in a positive or reverse direction along the mounting seat. However, in the above structure, the clamping plate can only clamp one workpiece that is compatible with the clamping surface of the clamping plate. During the forging process, there are workpieces of different shapes, such as Figure 5 The square steel A and round steel B shown in the figure have a single clamping surface that cannot adapt to clamping workpieces of different shapes. Summary of the invention

[0003] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0004] A clamp is provided, which can be adapted to clamp workpieces of different shapes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamp, comprising a driving seat and a driving device arranged in the driving seat, characterized in that: the driving seat is connected with a clamping seat, the clamping seat is provided with a cross-shaped clamping groove, the clamping groove comprises a longitudinal clamping groove which is arranged longitudinally and coaxial with the output direction of the output end of the driving device and a transverse clamping groove which is perpendicular to the longitudinal clamping groove, the middle of the longitudinal clamping groove is connected with the middle of the transverse clamping groove to form a connecting cavity, the longitudinal clamping groove is slidably provided with longitudinal slides on opposite sides of the connecting cavity, the transverse clamping groove is slidably provided with transverse slides on opposite sides of the connecting cavity, the longitudinal slide close to the driving seat is linked to the output end of the driving device, a linkage device is provided between the longitudinal slide and the adjacent transverse slide, so that when the longitudinal slides are synchronously displaced close to each other, the transverse slides are synchronously displaced away from each other, or when the longitudinal slides are synchronously displaced away from each other, the transverse slides are synchronously displaced close to each other, a longitudinal clamping claw is provided above each of the longitudinal slides, a transverse clamping claw is provided below each of the transverse slides, and the longitudinal clamping claw and the transverse clamping claw are respectively provided with different clamping surfaces.

[0006] The utility model with the above characteristics is provided with transverse clamping jaws and longitudinal clamping jaws with different clamping surfaces, so as to achieve clamping of workpieces with different shapes.

[0007] The utility model is further configured as follows: the linkage device comprises a linkage rod, the middle portion of each longitudinal slide is respectively connected to the middle portion of an adjacent transverse slide via a linkage rod, and both ends of the linkage rod are respectively hingedly connected to the transverse slide and the longitudinal slide.

[0008] The utility model with the above-mentioned characteristics: the driving device drives the longitudinal slide connected to it to slide in the longitudinal slide groove. When the longitudinal slide connected to the driving device moves away from the driving seat, the linkage rod drives the transverse slide to move in the transverse slide groove, and the two transverse slides move away from each other in opposite directions synchronously. At the same time, the linkage rod drives the other longitudinal slide to move synchronously toward the longitudinal slide connected to the driving device, thereby realizing clamping in different directions driven by a single driving device.

[0009] A further configuration of the utility model is that the longitudinal clamping jaw is provided with a first clamping surface, and the transverse clamping jaw is provided with a second clamping surface, the first clamping surface clamps and adapts to round steel, and the second clamping surface clamps and adapts to square steel.

[0010] The utility model with the above characteristics has the longitudinal clamping jaws and the transverse clamping jaws with different clamping surfaces, and can clamp workpieces with different clamping requirements.

[0011] A further configuration of the utility model is that the lengths of the longitudinal clamping grooves on both sides of the connecting cavity are the same, and the lengths of the transverse clamping grooves on both sides of the linkage cavity are the same.

[0012] The utility model with the above-mentioned features ensures that the displacement distances of the longitudinal slide or the transverse slide in the same direction are the same.

[0013] The beneficial effect of the utility model is that the longitudinal clamping jaws and the transverse clamping jaws with different clamping surfaces can adapt to workpieces with different clamping requirements.

[0014] The utility model is further described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
