[0022] Example 1

[0023] As shown in the figure, one end of the bridge plate 1 is fixedly connected to the bridge plate connecting plate 8 by bolts. Multiple groups of positioning components are arranged at intervals on the bridge plate 1. The positioning component consists of two positioning plates 3. The positioning plates 3 are in an inverted "L" shape. The two positioning plates 3 are relatively installed on the bridge plate 1. The product 4 is placed between the two positioning plates 3 of the positioning component.

A second groove adapted to the blocking block 2 is provided on the bridge plate. The telescopic end of the second hydraulic cylinder 7 installed under the bridge plate 1 passes through the bottom of the second groove and is connected to the blocking block 2.

[0025] The first hydraulic cylinder 6 is fixedly installed under the bridge plate 1 through the hydraulic cylinder connecting plate 5. The telescopic end of the first hydraulic cylinder 6 passes through the first groove provided on the bridge plate 1 and is adapted to the clamping block 8 and is connected to the clamping block 8. The position of the clamping block 8 is located between the two positioning plates 3 in the positioning assembly.

[0026] like Figure 1 As shown, the number of the first hydraulic cylinder 6 and the second hydraulic cylinder is 4, which is the same as the number of the positioning assemblies.

Then, the first hydraulic cylinder 6 is activated to control the clamping block 3 located below the product 4 to rise to clamp the product 4. The top two ends of the product 4 are respectively limited by the horizontal plate positions of the inverted "L"-shaped positioning plate 3. The product 4 is quickly clamped by the clamping block 8 and the horizontal plate of the positioning plate 3.

[0029] After the clamping is completed, the second hydraulic cylinder 8 is activated to control the stop block 2 to move down into the groove provided on the bridge plate, so that the front side, the back side and the top middle position of the product 4 can be processed, effectively reducing the problem of frequent replacement of machining tools and multiple machining steps;

[0030] Four sets of positioning components are set on the bridge plate 1 to expand the fixed stations, so that the products can be fixed at four stations for processing, thereby improving product processing efficiency and saving processing time.
