Description

Eccentric wheel clamping mechanism applied to welding fixture

Technical Field

The utility model belongs to welding jig in the commercial car automobile body processing especially applies to welding jig's eccentric wheel clamping mechanism.

Background

In the welding process of the commercial vehicle body, a plurality of parts have undersized reserved spaces, and the common positioning and pressing device can not be implemented directly or has a complex structure, so that the manufacturing and the use are inconvenient.

Disclosure of Invention

In order to overcome the ordinary location closing device of prior art and can't implement under the condition of part headspace undersize in commercial car automobile body welding process, the utility model provides an apply to welding jig's eccentric wheel clamping mechanism adopts eccentric cam to be application of force portion, and the mode through indirect transmission clamp force realizes pressing from both sides tightly.

Therefore, the technical scheme of the utility model is that: apply to welding jig's eccentric wheel clamping mechanism, including the support body, its characterized in that: the support body is fixedly provided with a U-shaped connecting seat through welding, a pressing arm is arranged along the vertical direction and is hinged to a stand column function part of the U-shaped connecting seat through a pressing arm connecting pin shaft, the upper part of the pressing arm is a clamping implementation end, and the lower part of the pressing arm is an eccentric cam force application end;

the upper clamping implementing end of the pressing arm is fixedly connected with a pressing block connecting plate through a first screw, and pressing blocks are arranged at two ends of the pressing block connecting plate; the lower eccentric cam force application end of the pressing arm is fixedly connected with a front stop block through a third screw;

the eccentric cam is hinged to the bottom of the U-shaped connecting seat through an eccentric cam connecting pin shaft, the outer circle of the eccentric cam is in contact with the front stop block, and a handle is connected to the eccentric cam.

The technical scheme is further limited as follows: two ends of the press block connecting plate are respectively connected with press blocks through second screws; the split structure is convenient to manufacture and assemble and low in cost.

The utility model has the advantages that: the utility model adopts the eccentric cam as the force application part, the pressing arm is pushed to swing through the front stop block, so as to drive the pressing block to clamp, the clamping is realized through the indirect transmission of the clamping force, the clamping force application part is far away from the clamping position, the implementation is realized under the condition that the reserved space of the part is too small in the welding process of the commercial vehicle body, and the clamping structure is simplified; additionally, the utility model discloses an eccentric cam size can set up wantonly with opening the angle, and other structures can be general, and simple structure is compact, and the specification is diversified, can effectively utilize in narrow and small space.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Shown in the figure: 1. a support body; 1-1, a U-shaped connecting seat; 1-1-1, a column function part; 2. the pressing arm is connected with a pin shaft; 3. a pressing arm; 4. a pressing block connecting plate; 5. briquetting; 6. a front stop block; 7. an eccentric cam; 8. a handle; 9. the eccentric cam is connected with the pin shaft.

Detailed Description

The invention is further described below with reference to the accompanying drawings: as shown in fig. 1, the eccentric wheel clamping mechanism applied to the welding fixture comprises a support body 1, wherein a U-shaped connecting seat 1-1 is fixedly arranged on the support body through welding, a pressing arm 3 is arranged along the vertical direction and is hinged to a stand column functional part 1-1-1 of the U-shaped connecting seat through a pressing arm connecting pin shaft 2, the upper part of the pressing arm 3 is a clamping implementation end, and the lower part of the pressing arm 3 is an eccentric cam implementation end;

the upper clamping implementing end of the pressing arm 3 is fixedly connected with a pressing block connecting plate 4 through a first screw, and two ends of the pressing block connecting plate 4 are connected with pressing blocks 5 through second screws; the lower eccentric cam force application end of the pressing arm 3 is fixedly connected with a front stop block 6 through a third screw; the eccentric cam 7 is hinged to the bottom of the U-shaped connecting seat 1-1 through an eccentric cam connecting pin shaft 9, the excircle of the eccentric cam 7 is in contact with the front stop block 6, and the eccentric cam 7 is connected with a handle 8.

Further explanation of the above technical solution: the connection mode of the pressing block 5 and the pressing block connecting plate 4 is not limited to screw connection; or the pressing block and the pressing block connecting plate are of an integrated integral structure.

For those skilled in the art, simple combination, equivalent replacement, and further improvement without departing from the technical concept or essential features of the present invention should be included in the protection scope of the present invention.
