the section of the splint 1 is in a U-shaped structure; the U-shaped openings of the two clamping plates 1 are oppositely arranged; the bushing 2 is located on the back of the U-shaped opening of the splint 1.

Further, the main rod comprises a main rod upper part 4 and a main rod lower part 5;

the upper part 4 of the main rod and the lower part 5 of the main rod are welded; the end part of the hook component 6 is fixedly connected with the upper part 4 of the main rod through the matching of a bolt and a nut 7; the plurality of clamping plates 1 are sleeved on the lower part 5 of the main rod.

Further, the hook assembly 6 includes a U-shaped hook.

The technical effects of the utility model: the utility model discloses fixture device to sheet type work piece, has realized loosening and screwing up the work piece through the position of movable clamp plate 1 and bush 2 and rotation bolt 3, and convenient, swift, accurately carry out the clamping to the work piece, improved work efficiency. The clamp is changed from original small-area contact into point contact, so that the problems that water stains are remained on the surface of a workpiece and the clamp marks are thoroughly solved, and the product quality is improved. The novel fixture device has higher practical value in the anodic oxidation processing process.

Detailed Description

Example 1

Fig. 1 is a schematic structural diagram of a clamping device, and as shown in fig. 1, in the present embodiment, a clamping device for anodizing a sheet-like workpiece is provided, where the clamping device includes a plurality of clamping plates 1, a main rod, and a hook assembly 6; the plurality of clamping plates 1 are arranged oppositely in pairs, and thin plate parts are clamped between the two clamping plates 1; the plurality of clamping plates 1 are sleeved on the main rod and fixedly connected with the main rod; the hook component 6 is fixedly connected with one end of the main rod.

As shown in fig. 1, the boom comprises a boom upper portion 4 and a boom lower portion 5; the upper part 4 of the main rod and the lower part 5 of the main rod are welded; the end part of the hook component 6 is fixedly connected with the upper part 4 of the main rod through the matching of a bolt and a nut 7; the plurality of clamping plates 1 are sleeved on the lower part 5 of the main rod. The hook assembly 6 comprises a U-shaped hook.

Fig. 3 is an axial view of a bush, fig. 4 is a side view of the bush, and as shown in fig. 3 and fig. 4, the clamping device further comprises a bush 2, and the bush 2 is fixedly connected with the clamping plate 1; the bush 2 is sleeved on the lower part 5 of the main rod and is fixedly connected with the main rod through a fastener.

In the embodiment, the bushings 2 and the clamping plates 1 are correspondingly welded one by one; the fastener is bolt 3, and bush 2 passes through bolt 3 and mobile jib fixed connection. The section of the splint 1 is in a U-shaped structure; the U-shaped openings of the two clamping plates 1 are oppositely arranged; the bushing 2 is located on the back of the U-shaped opening of the splint 1.
