Description

Technical Field

[0001] The utility model relates to the technical field of flexible tooling, in particular to a new type of soft clamping tooling. Background Art

[0002] Clamping tooling is a general term for fixtures, mechanical devices or equipment that play a cooperating and auxiliary role in the assembly and welding process of welded structure production.

[0003] Traditional clamping tooling generally consists of three parts: a locator, a clamping mechanism, and a clamping base. In welding operations, complex fixtures with multiple different clamping mechanisms and locators installed on the clamping base are often used. The operation is extremely cumbersome, and under normal circumstances, this clamping tooling can only be used to clamp a certain type of workpiece. When replacing a workpiece with another structure, the clamping tooling is not universal. Utility Model Content

[0004] In view of the above problems existing in the prior art, the purpose of the embodiments of the present utility model is to provide a new soft clamping tool, which is convenient to use for clamping a workpiece and has a stable clamping effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a new type of soft clamping tool, including a tool group, the tool group includes a plurality of flexible vises arranged side by side, the flexible vise includes a clamping strip and a plurality of first-level arc-shaped clamps, the clamping strip is provided with a plurality of first-level arc-shaped slots, the outer side wall of the first-level arc-shaped clamp is provided with an arc-shaped slider 1, and the first-level arc-shaped clamp is slidably arranged in the first-level arc-shaped slot by the arc-shaped slider 1.

[0006] Furthermore, two secondary arc-shaped grooves are provided on the primary arc-shaped pliers, a secondary arc-shaped pliers is provided in the secondary arc-shaped groove, an arc-shaped slider 2 is provided on the outer side wall of the secondary arc-shaped pliers, and the secondary arc-shaped pliers is slidably arranged in the secondary arc-shaped groove by the arc-shaped slider 2.

[0007] Furthermore, it includes a fastener, which includes a strip plate and multiple bolts, and the multiple bolts are vertically fixed to the strip plate. A thickened plate is fixed to the side of the clamping strip away from the primary arc-shaped slide groove, and a plurality of through holes are opened on the thickened plate. The bolts are inserted into the through holes to connect the multiple flexible vises in series, and a nut is engaged on one end of the bolt that passes through the multiple flexible vises.

[0008] Furthermore, it includes a tooling frame, which includes multiple clamping strips and widening plates fixed to both ends of the multiple clamping strips. The tooling frame is connected to the tooling group in a manner that the clamping strips are embedded in the gaps between the clamping strips.

[0009] Furthermore, it includes a pressure plate, wherein sliding bars are vertically fixed at both ends of the pressure plate, and a sliding rail is provided on the widened plate. The pressure plate is connected to the widened plate in such a way that the sliding bar is slidably arranged on the sliding rail, and the end face of the pressure plate close to the card bar is in contact with the card bar.

[0010] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0011] 1. When in use, place the soft clamping tool with the first-level arc clamp facing the workpiece to be clamped. When the soft clamping tool abuts the surface of the workpiece to be clamped, the first-level arc clamp will rotate in the first-level arc chute, and the angle of the first-level arc clamp end will change, matching the shape of the workpiece surface to clamp the workpiece. Similarly, the second-level arc clamp will also rotate in the second-level arc chute, and the angle of its end will change, matching the shape of the workpiece surface. The clamping accuracy is greater, and more dense force points can be added on the workpiece surface, clamping the workpiece more stably.

[0012] 2. In some embodiments, two flexible clamping devices may be used to clamp the workpiece. Both flexible clamping devices use primary curved clamps to clamp the workpiece on opposite sides. The primary curved clamps and secondary curved clamps on the two flexible clamping devices are rotated to an angle that matches the surface shape of the workpiece they are in contact with, thereby enabling fast and stable clamping of the workpiece.

[0013] 3. After completing the clamping, directly remove the two soft clamping tools from the workpiece and place them horizontally. Under the action of gravity, the first-level arc clamp and the second-level arc clamp can be quickly reset to facilitate the next clamping work. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] An arc-shaped slider 1131 is provided on the outer side wall of the first-level arc-shaped clamp 113 , and the first-level arc-shaped clamp 113 is slidably disposed in the first-level arc-shaped sliding groove 1120 via the arc-shaped slider 1131 .

[0047] Two secondary arc-shaped slots 1130 are provided on the primary arc-shaped clamp 113, and a secondary arc-shaped clamp 1132 is provided in the secondary arc-shaped slot 1130.
