Abstract
The invention discloses a positioning structure for a white car body welding production line. The positioning structure for the white car body welding production line comprises a supporting base and an air cylinder, a positioning pin is connected with an outer end head of a piston rod and the piston rod matches with the outer end head of the air cylinder, the positioning pin is in a cylindrical structure, and a fine adjustment sliding mechanism is arranged between the supporting base and the air cylinder. Positioning accuracy of the cylindrical positioning pin is guaranteed, the positioning pin is accurate and firm, the motion is flexible and reliable, and the whole structure is simple.
Description
Technical field
The present invention relates to a kind of location structure, particularly a kind of for the location structure on the automobile body-in-white welding production line.
Background technology
In automobile manufacture industry, more and more higher to the quality requirement of the various parts of automobile, be also more and more stricter to the positioning accuracy request that is positioned at the body in white parts on car body welding producing line.
Present location to the automobile body-in-white weld jig is mainly to utilize the detent mechanism with the prismatic alignment pin to position, and the locate mode of prismatic pin is difficult to guarantee precision, the final precision that is welded, the complicated integral structure of detent mechanism, the very flexible of affecting.
Summary of the invention
The purpose of this invention is to provide that a kind of simple in structure, flexible movements are reliable, accurate positioning, the precision that is welded are high is used for location structure on the automobile body-in-white welding production line, overcome the deficiencies in the prior art.
Of the present invention for the location structure on the automobile body-in-white welding production line, comprise bearing, cylinder, the piston rod external end head that matches with cylinder is connected with alignment pin, and described alignment pin is cylindrical-shaped structure; Be provided with the fine setting slide mechanism between bearing and cylinder.
Of the present invention for the location structure on the automobile body-in-white welding production line, the structure of wherein said fine setting slide mechanism is to be fixed with fixed head on bearing, establish sliding-rail sliding formula sliding connector between fixed head and movable plate, be connected by rectangular-shaped contiguous block between described cylinder and movable plate, be provided with first group and adjust pad between contiguous block and movable plate, be provided with second group and adjust pad between contiguous block and cylinder.
Of the present invention for the location structure on the automobile body-in-white welding production line, wherein said sliding connector comprises that the slide rail that is fixedly connected with fixed head and the slide block that matches with slide rail and be fixedly connected with movable plate, described sliding connector have two groups and upper and lower to be arrangeding in parallel; Both sides, described movable plate top are connected with mobile by piece, and bearing both sides are fixedly connected with end plate, and the inboard of end plate is connected with fixing by piece, mobilely match by piece with fixing by piece.
Of the present invention for the location structure on the automobile body-in-white welding production line, owing between the cylinder that alignment pin is installed and bearing, micro-moving-member being arranged, and be provided with the adjustment pad of both direction, can float voluntarily during the location and put in place, can reach servo-actuated purpose, guarantee the positioning accuracy of cylindrical alignment pin, accurately firmly, flexible movements are reliable, and overall structure is simple.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 12 is bearing, and 11 is cylinder.The piston rod external end head that matches with cylinder 11 is connected with alignment pin 8, and alignment pin 8 is cylindrical-shaped structure, and namely the section of alignment pin 8 is rounded.
Be provided with the fine setting slide mechanism between bearing 12 and cylinder 11, the structure of this fine setting slide mechanism is the fixed head 2 that is bolted vertical setting on bearing 12, establish sliding-rail sliding formula sliding connector between fixed head 2 and movable plate 13, sliding connector comprises the slide rail 14 and slide block 1 that match with slide rail 14 and that be fixedly connected with movable plate 13 that is fixedly connected with fixed head 2, and sliding connector has two groups and upper and lower to be arrangeding in parallel.
Movable plate 13 both sides, top are connected with mobile by piece 6, bearing 12 both sides are fixedly connected with end plate 4, the inboard of end plate 4 is connected with fixing by piece 5, the mobile piece 6 that leans on matches by piece 5 with fixing, namely move when moving with movable plate 13 by piece 6, can be undertaken spacingly by piece 5 by fixing, make movable plate 13 that the displacement of trace be arranged with respect to bearing 12, this displacement for mobile by piece 6 and the fixing gap of leaning between piece 5.
Be connected by rectangular-shaped contiguous block 9 between cylinder 11 and movable plate 13, be provided with first group and adjust pad 3 between contiguous block 9 and movable plate 13, be provided with second group of adjustment pad 10 between contiguous block 9 and cylinder 11.Also can determine relative position between cylinder 11 and bearing 12 by each quantity of adjusting pad.Protective cover 7 is installed above bearing 12.
Bearing 12 is fixed on the frame of welding and assembling production lines by bolt during installation, cylinder 11 joins with air control unit, the action of cylinder 11 can drive alignment pin 8 actions, and certain locating hole of the body in white on the insertion car body welding producing line positions body in white, in position fixing process, movable plate 13 can have with respect to bearing 12 displacement of trace, and by fixing by piece 5 with mobilely undertaken spacingly by piece 6, each change of adjusting pad quantity is the relative position between adjustable cylinder 11 and bearing 12 also.Guaranteed the positioning accuracy of cylindrical alignment pin, accurately firmly, flexible movements are reliable, and overall structure is simple.
