Abstract
The utility model relates to a double-floating positioning mechanism, which comprises a substrate, wherein an oscillating rod is hinged under the substrate, two vertically arranged sliding rods which are parallel to each other are matched on the substrate in a sliding mode, and the lower ends of the two sliding rods are respectively connected to two ends of the oscillating rod. According to the double-floating positioning mechanism, a third point of a three-point positioning mechanism is replaced by two points, the stability in positioning is improved, and workpiece overturning can be effectively prevented. According to the double-floating positioning mechanism, the positioning precision is improved, so that the processing precision of workpieces is improved.
Description
Technical field
The utility model relates to frock clamp, specifically a kind of pair of floating positioning device.
Background technology
Along with improving constantly of automobilism speed, the reliability that people control driving also improves constantly, thereby the requirement to the running crane control device of vehicle is also constantly improving, and this just also has higher requirement to the processing and manufacturing precision of the controlling organization of travelled by vehicle section.
During processing vehicle control device housing, when it is positioned, often adopt three-point positioning mechanism, the mode that namely adopts three points to limit a plane is located.Because there is molten error in workpiece blank, this locate mode is easily toppled, thereby causes the location unstable, affects machining accuracy, even causes the processing accident.
Summary of the invention
The utility model provides a kind of pair of floating positioning device for the problems referred to above, and this detent mechanism is located reliable, can guarantee the machining accuracy of workpiece.
According to the technical solution of the utility model: a kind of pair of floating positioning device, comprise matrix, the below of described matrix is hinged with swing arm, is sliding combined with the sliding bar of two parallel vertical layouts on described matrix, and the lower end of described two sliding bars is connected to the two ends of described swing arm.
Be provided with sliding sleeve between described sliding bar and described matrix, described sliding sleeve is fixed on described matrix, and described sliding bar is slidably fitted in described sliding sleeve.
The two ends of described sliding sleeve are respectively arranged with dust cap and lower dust cap, and described upper dust cap and described lower dust cap are separately fixed on described matrix.
Be respectively arranged with dust ring between described upper dust cap and described lower dust cap and described sliding bar.
The below of described matrix is fixed with revolving bed, and described swing arm is hinged on described revolving bed by gyroaxis.
The two ends of described swing arm are respectively arranged with T-shaped groove, and the lower end of described sliding bar is inlaid in described T-shaped groove.
Technique effect of the present utility model is: the utility model replaces two points that float that thirdly adopt of three-point positioning mechanism, and the stability when having improved the location can prevent effectively that workpiece from toppling; The utility model has improved positioning accuracy, thereby has improved the machining accuracy of workpiece.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, comprise sliding bar 1, dust ring 2, upper dust cap 3, matrix 4, sliding sleeve 5, lower dust cap 6, revolving bed 7, swing arm 8, gyroaxis 9 etc.
As shown in Figure 1, the utility model is a kind of pair of floating positioning device, and two fixing points in three-point positioning mechanism provide the 3rd fixing point after having determined.
This pair floating positioning device comprises matrix 4, and the below of matrix 4 is hinged with swing arm 8.The below of matrix 4 is fixed with revolving bed 7, and swing arm 8 is hinged on revolving bed 7 by gyroaxis 9, and swing arm 8 can swing centered by gyroaxis 9.
Be sliding combined with the sliding bar 1 of two parallel vertical layouts on matrix 4.Be provided with sliding sleeve 5 between sliding bar 1 and matrix 4, sliding sleeve 5 is fixed on matrix 4, and sliding bar 1 is slidably fitted in sliding sleeve 5.The two ends of sliding sleeve 5 are respectively arranged with dust cap 3 and lower dust cap 6, and upper dust cap 3 and lower dust cap 6 are separately fixed on matrix 4.Dust ring 2 is respectively arranged with dust ring 2 between upper dust cap 3 and lower dust cap 6 and sliding bar 1, in can prevent that foreign matter from entering.
The lower end of two sliding bars 1 is connected to the two ends of swing arm 8.The two ends of swing arm 8 are respectively arranged with T-shaped groove, and the lower end of sliding bar 1 is inlaid in T-shaped groove.
Operation principle of the present utility model is as follows: after workpiece is arranged on the utility model, wherein a sliding bar 1 contacts with workpiece, under the Action of Gravity Field of workpiece, this root sliding bar 1 moves down in sliding sleeve 5, drives swing arm 9 and swings, and the other end of swing arm 9 is upturned, driving the sliding bar 1 that is connected with swing arm 9 other ends moves up, until this sliding bar 1 contacts with workpiece, automatically reach a kind of poised state, two sliding bars 1 no longer move.
The utility model replaces two points that thirdly adopt to float of three-point positioning mechanism, has reduced the harmful effect that the molten error of workpiece blank causes, and stability and positioning accuracy when having improved the location can prevent effectively that workpiece from toppling; The utility model is simple in structure, and is safe and reliable, and favorable sealing property is easy to maintenance.
