Abstract
A measuring and testing device for parallel degree of front-back guide rails of a car door assembly comprises a slide bar (4), a slide sleeve (13) and a displacement measuring device, wherein, one end of the slide bar (4) is arranged in the slide sleeve (13) and can slide in the slide sleeve (13), and the displacement measuring device is used for measuring displacement of the slide bar (4) sliding in the slide sleeve (13). In the invention, the measuring and testing device is arranged in the front-back guide rails of the car door assembly, and two ends of the measuring device are still contacted with the front-back guide rails while the measuring and testing device moves upwards and downwards; and when the front-back guide rails are not parallel during the movement process, the slide bar (4) slides in the slide sleeve (13) to record displacement of the slide bar (4) sliding in the slide sleeve (13) measured by the measuring device so as to measure the parallel degree of the front-back guide rails of the car door assembly. The total measuring and testing device has simple structure, high safety, easy operation, convenient maintenance, high reliability, high measurement precision and strong visibility.
Description
Technical field
The present invention relates to a kind of measuring and testing device for parallel degree of front-back guide rails of car door assembly, is the special purpose test equipment of single parallel degree of front-back guide rails of car door assembly mechanical detection specifically.
Background technology
It has been the emphasis that automobile industry is difficult to capture that lifting glass for vehicle window operates steadily always.Two parallel lines distances that guide rail is vertical before and after the single in theory car door should be consistent, but the glass of entire vehicle jacking system it limited by condition because of many-sided objective factors such as manufacturing process, manufacturing accuracy, materials, be difficult to guarantee consistance and the matching that it is whole and move smooth and easy stability.The depth of parallelism of guide rail is particularly important before and after in the lifting glass for vehicle window system, if two parallel segments of measuring vertical with the front and back guide rail are up big and down small, will cause glass for vehicle window rise shake, if two parallel segments of measuring vertical with the front and back guide rail are up-small and down-big, will cause the swing that descends.So must carry out the depth of parallelism at the front and back guide rail of single car door assembly detects.Do not appear in the newspapers as yet at commercial car parallel degree of front-back guide rails of car door assembly special measurement device at present, the special purpose test equipment of domestic this respect still belongs to blank.
Summary of the invention
Problem at prior art exists the object of the present invention is to provide a kind of parallel degree of front-back guide rails of car door assembly measurement mechanism, can measure parallel degree of front-back guide rails of car door assembly.
For achieving the above object, the invention provides a kind of measuring and testing device for parallel degree of front-back guide rails of car door assembly, comprise slide bar, sliding sleeve and displacement measuring device, an end of slide bar is installed in the sliding sleeve, and can in sliding sleeve, slide, displacement measuring device is used to measure the displacement that slide bar slides in sliding sleeve.
Experiment with measuring device of the present invention is assembled in the guide rail of car door assembly front and back, move up and down the experiment with measuring device, experiment with measuring device two ends contact with the front and back guide rail all the time when mobile, when current rear rail is not parallel in moving process, slide bar slides in sliding sleeve, the displacement of slide bar in sliding sleeve that record is measured by displacement measuring device, thereby the depth of parallelism of guide rail before and after the measurement car door assembly.
Slide bar is vertical with guide rail before and after the car door assembly with sliding sleeve.
Be provided with volute spring between slide bar and the sliding sleeve.
The end that slide bar contacts with door rail is provided with plunger roller, and the end that sliding sleeve contacts with door rail is provided with the sliding sleeve roller.
Experiment with measuring device of the present invention also comprises inclined support bar and vertical supporting bar, and an end of inclined support bar is fixedlyed connected with sliding sleeve is angled, and the other end contacts with door rail, fixedlys connected with inclined support bar with sliding sleeve respectively in the vertical supporting bar two ends.
The end that inclined support bar contacts with door rail is provided with the inclined support bar roller.
Displacement measuring device comprises the displacement stator that is fixed on the slide bar, is fixed on fixed support that is used for fixing displacement transducer and Displaying Meter on the sliding sleeve.
Test unit of the present invention is fitted in the guide rail of car door assembly front and back, move up as requested for mobile basic point with rear portion (two rollers), when current rear rail is not parallel in moving process, slide bar slides in sliding sleeve, the slide bar that record is shown by Displaying Meter is at the concrete numerical value of sliding sleeve intrinsic displacement amount, thereby measures the depth of parallelism of guide rail before and after the car door assembly.
The present invention has realized that with a sidecar door guide rail be that mobile basic point moves up, cooperate displacement transducer etc. partly to measure the depth of parallelism of guide rail before and after the car door assembly, the whole test apparatus structure is simple, safe, easy operating, be convenient to maintenances, reliability height, measuring accuracy height, visuality by force.
