Auxiliary detection device of three-coordinate measuring machine

Abstract

The invention discloses an auxiliary detection device of a three-coordinate measuring machine. The auxiliary detection device comprises a bottom plate and two support beams arranged on the bottom plate, wherein three clamping mechanisms are arranged on the two support beams, one clamping mechanism is clamped on a mounting hole at the upper part of a product, and the other two clamping mechanisms are respectively clamped on two mounting holes at the lower part of the product; each clamping mechanism comprises a fixed clamping plate and a movable clamping plate; the fixed clamping plates are fixedly connected to the corresponding supporting beams; each movable clamping plate and the corresponding fixed clamping plate are oppositely arranged, a positioning column, a pressing piece and a positioning pin are sequentially arranged between the movable clamping plate and the fixed clamping plate; and positioning assembly of the product is achieved by means of the positioning columns, connection of the fixed clamping plates and the movable clamping plates is achieved by means of the pressing pieces, and relative positioning of the fixed clamping plates and the movable clamping plates is achieved by means of the positioning pins. The auxiliary detection device can realize full-size measurement of the product through sequential clamping, can clamp and fix the product quickly and conveniently, and has good repeatability and stability.

Description

technical field [0001] The invention relates to the field of size detection, in particular to an auxiliary detection device for a three-coordinate measuring machine. Background technique [0002] Boxes, shells, gears, blades and other products in machinery, automobiles, molds, aviation and other industries need to use a three-coordinate measuring machine for precise testing of their size, shape and shape and position tolerances, so as to complete parts testing, shape measurement, tasks such as process control. Before testing, it is necessary to clamp and fix the product on the three-coordinate measuring machine according to the drawing, shape, process, assembly, etc. of the workpiece to ensure the stability and accuracy of the measurement. However, the existing clamping and fixing mechanism will inevitably block part of the product structure after clamping and affect the detection. In order to solve this problem, the product is mainly adjusted multiple times and clamped mul...

Problems solved by technology

However, the existing clamping and fixing mechanism will inevitably block part of the product structure after clamping and affect the detection. In order to solve this problem, the product is mainly adjusted multiple times and clamped multiple times, so that The blocked structure on the product can be exposed and detected outside the clamping and fixing mechanism. This operation method is complicated and inefficient, and multiple position adjustments and multiple clamping will affect the accuracy of product detection
