Description

Measuring tool for measuring fixed point distance on inclined plane of part

Technical Field

The utility model relates to an automobile parts production field especially relates to a measure of fixed point distance on measuring part inclined plane.

Background

In the production process, in the field of automobile cold-formed part production, a measuring tool for measuring the fixed-point distance on the inclined surface of a part is needed, the measuring tool is used for rapidly measuring and checking the distance between two fixed points on two inclined surfaces of a special-shaped part with a complex shape in a production field and final delivery inspection, recording numerical values and judging whether the special-shaped part is qualified or not, and accordingly, a producer or a final inspector judges whether the special-shaped part can be produced or delivered.

Specifically, the measurement object is an H-shaped blind hole tubular part. The distance between M points and N points fixed on the end faces of the two sides of the blind plate in the middle of the pipe in the drawing is 18.1 +/-0.15 mm, the precision is high, and if the deviation exists, the pipe is judged to be an unqualified product.

The piece is produced in a cold heading mode, the production speed is high, the normal production speed is 60 pieces/minute, the size customer defines the key size, the production line quickly judges that the size is qualified, data are recorded, and 100% of all produced products are guaranteed to be qualified.

The part is used for electronic parking systems of multiple vehicle types, and the product is subjected to subsequent treatment and then precisely assembled with another screw rod, so that if the precision assembly is out of tolerance, the function is weakened or the function is failed. The size requirements are high.

The part can measure all dimensions by using three coordinates, but because the dimensions are critical dimensions, the results of the dimensions need to be recorded, the CPK and the PPK are calculated and the stability of the dimensions needs to be controlled in the production process. Due to the fact that the three-coordinate measuring efficiency is low, the three-coordinate measuring device cannot keep up with the beat of a production field, a common height gauge cannot accurately position M points and N points on the inclined plane of the middle blind plate, accurate measurement cannot be conducted, measuring errors are large, and the accuracy requirement of +/-0.15 mm cannot be guaranteed.

In view of the above, a tool capable of rapidly and accurately detecting the defect is urgently needed in the production field.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a measuring tool of fixed point distance on the measurement part inclined plane to prior art's not enough.

In order to achieve the above object, the utility model provides a measure of fixed point distance on measurement part inclined plane, its major structure mainly comprises following part: percentage table, fixed cover, measuring stick and main part.

Preferably, the main body part is assembled by a bottom plate, a vertical column, a top block and an intermediate block and is connected by a bolt.

Preferably, the fixing sleeve is positioned and fastened by a pin and a bolt, the measuring rod can freely slide up and down under the interaction of a spring and external force, the rear end of the measuring rod is contacted with a probe of the dial indicator, and the front end of the measuring rod is contacted with a measuring point of a part.

Preferably, the fixing sleeve is accurately positioned on the ejector block by using a pin, and a sliding groove in the ejector block ensures the accurate position of the measuring point.

Compared with the prior art, the utility model provides a this measuring tool can be fast accurate come out required dimensional measurement, and other measurement methods relatively have simplified measurement greatly and have compared with the measurement mode of three-coordinate, and efficiency improves the multifold, can guide the production site fast and guide, adopts this operation of examining in addition, and the reliability has very big improvement, and the measuring result is highly credible, and the probability of erroneous judgement is little to neglecting.
