Two guide rail weldering tire clamp positioning mechanisms
Technical field
The utility model relates to a kind of two guide rail weldering tire clamp positioning mechanism.
Background technology
Generally apply to be widely used in automobile fixture design at weldering tire clamp positioning mechanism, the main tailpiece of the piston rod at cylinder (being front end) adopting carries out spacing mode at present, this kind of mode structure space needs larger, often there is the situation of constructive interference, for fear of interference, many times all limited block mount pad is designed to polymorphic structure, need to more consider the strength problem of limited block and mount pad, simultaneously, front end limit method, for automobile fixture debugging, there is inconvenience, and the common thin wall cylinder low precision on market, cannot guarantee the vehicle body location that precision is higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of two guide rail weldering tire clamp positioning mechanism, and its structure has been saved space, processing, all fairly simple convenience and registrations of assembling.
For solving the problems of the technologies described above, two guide rail weldering tire clamp positioning mechanisms with following design feature are provided: it comprises the holder being connected in soldering cramping apparatus frame, its design feature is: positioning cylinder is equipped with at the rear portion of holder, two guide rails that be arranged in parallel are also equipped with in the front portion of holder, on guide rail, be connected with the supporting base being slidably matched with it, supporting base is provided with the bolt hole for being connected with weldering tire fixture, the piston rod of described positioning cylinder and the rear portion of supporting base are hinged, the front and rear of supporting base is equipped with respectively collision block, the limited block that lays respectively at supporting base front and rear is housed on holder.
Described holder is provided with along piston rod and stretches out multiple bolts hole that direction is arranged, described limited block by through the bolted of bolt hole on holder.
The top, rear portion of described supporting base is connected with Connection Block, and Connection Block is provided with otic placode, and the piston rod end of described positioning cylinder is connected on otic placode.
Adopt after said structure, the bolt installing by bolt hole is connected to weldering tire fixture on supporting base, positioning cylinder is connected on the holder being fixedly installed, start positioning cylinder, thereby drive supporting base to move forward and backward, the weldering tire fixture ordering about on supporting base moves forward and backward, because the front and back of supporting base arrange respectively collision block, and be provided with limited block, thereby can accurately control the stroke of positioning cylinder, adopt two closed slides can make moving forward and backward of supporting base more steady.
In sum, this mechanism utilizes guide rail to play supporting, guide effect, guarantee positioning cylinder running precision under external force, improve the precision of welding tooling fixture and then improved welding precision and the quality of automobile body-in-white, light steady while utilizing guide rail movement, have the characteristic of enough rigidity, Shi Gai mechanism operates steadily.This structure has the advantages such as manufacture is simple, flexible operation, cost is low, space hold is few.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the perspective view of Fig. 1.
The specific embodiment
Two guide rail weldering tire clamp positioning mechanisms as depicted in figs. 1 and 2, it comprises the holder 1 being connected in soldering cramping apparatus frame, positioning cylinder 2 is equipped with at the rear portion of holder 1, two guide rails that be arranged in parallel 3 are also equipped with in the front portion of holder 1, on guide rail 3, be connected with the supporting base 4 being slidably matched with it, the slide 8 coordinating with guide rail 3 is equipped with in the bottom that is supporting base 4, slide 8 is prior art with the concrete structure that guide rail 3 is slidably matched, supporting base 4 is provided with the bolt hole for being connected with weldering tire fixture, the rear portion of the piston rod of described positioning cylinder 2 and supporting base 4 is hinged, specifically, the top, rear portion of supporting base 4 is connected with Connection Block 7, Connection Block 7 is provided with otic placode, the piston rod end of described positioning cylinder 2 is connected on otic placode, the benefit arranging is like this to make the promotion of positioning cylinder piston rod more steady.The front and rear of supporting base 4 is equipped with respectively collision block 5, and the limited block 6 that lays respectively at supporting base 4 fronts and rear is housed on holder 1.
As depicted in figs. 1 and 2, holder 1 is provided with along piston rod and stretches out multiple bolts hole that direction is intervally arranged, described limited block 6 by the bolted through bolt hole on holder 1.The bolt that limited block 6 can be installed by different bolts hole is arranged on the diverse location of holder, thereby realizes the front and back variation of the position of limited block 6, and then guarantees the flexible stroke of the piston rod of positioning cylinder, guarantees the accurate location of weldering tire fixture.
The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, the equivalent variations based on concrete structure on the utility model and parts are replaced all in protection domain of the present utility model.
