Problems solved by technology
There is a gap between the positioning block and the second plate, which will affect the accuracy of positioning, and the clamping requirements for the plate are very high, especially the self-made equipment is relatively rough, and it is difficult to meet the requirements of precise positioning. It will often cause the board to be pinched, etc.
In order to overcome this kind of problem, the common practice is to install the plate with automatic equipment and then manually confirm it, and then clamp it. This not only wastes manpower, but also increases the workload of workers, and the effect is not very good, which will reduce the welding quality. work efficiency

Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0016] Such as figure 1 As shown, the present invention consists of a positioning block 1, a pressing block 2, a flat push arm 3, a first pin 4, a second pin 5, a spring 6 and a thimble 7. Described positioning block 1 is divided into horizontal arm 1a, vertical arm 1b and cantilever 1c three parts, and wherein horizontal arm 1a is perpendicular to vertical arm 1b, and the front end of horizontal arm 1a links to each other with the upper end of vertical arm 1b. 1a has mounting holes through its upper and lower surfaces. The root of the vertical arm 1b extends forward to form a cantilever 1c. The cantilever 1c is on the extension line of the horizontal arm 1a, and the top surface of the cantilever 1c is flush with the top surface of the horizontal arm 1a, and the bottom surface of the cantilever 1c is higher than the bottom surface of the horizontal arm 1a....

The invention discloses a combined fixture compaction device. A locating block is provided with a horizontal arm and a vertical arm, the root of the vertical arm extends forwards to form a cantilever, a press block is arranged below the cantilever, the left side and the right side of the press block are symmetrically provided with horizontal sliding arms, and the front end of each horizontal sliding arm is hinged with the press block by a first pin while the back end of the horizontal sliding arm is hinged with the vertical arm by a second pin. A blind hole with an opening upper end is arranged in the press block and is provided with a spring and an ejector pin internally, and the lower end of the ejector pin is propped against the spring while the upper end of the ejector pin is propped against the cantilever. The combined fixture compaction device disclosed by the invention can be used for accurately positioning panels in a welding process, greatly increases the welding efficiency of the panels when avoiding that the panels is broken in a clamping manner, reduces work output of workers, and has the characteristics of simple structure, easy machining and assembly, good reliability and the like.
Description
technical field [0001] The invention relates to a composite fixture pressing device, which is used for welding and positioning of plate parts. Background technique [0002] At present, each automobile manufacturer needs to use a fixture positioning block to position the two plates when welding the top cover of the car. Such as Figure 4 , Figure 5 As shown, the conventional positioning block 1 is L-shaped, the horizontal arm 1a of the positioning block 1 is fixed to one end of the swing arm 8, and the other end of the swing arm 8 is hinged to the telescopic rod of the piston cylinder 9. When welding, the first plate 10 and the second plate 11 are stacked in sequence and then supported on the positioning seat 12. The second plate 11 has an L-shaped working surface, and the horizontal working surface of the second plate 11 Fit the first plate 10, and then operate the piston cylinder 9 to make the telescopic rod of the piston cylinder 9 drive the swing arm 8 to rotate until ...
