Description

Non-contact measurement electronic gauge

Technical Field

The utility model belongs to the technical field of utensil is examined to the electron, concretely relates to utensil is examined to non-contact measurement electron.

Background

The traditional mechanical inspection tool is mainly used for measurement, and for a control means of product size, the size of the whole molded surface of a product is represented by measuring a plurality of points, so that the detection speed and the detection accuracy of a product measuring point are the main standards for measuring a detection means. 1. At present, the traditional mechanical inspection tool is mainly used in the detection stage of the production process of automobile parts, a meter punching hole is formed in each measuring point of the traditional mechanical inspection tool, a common dial indicator is inserted into each measuring point for measurement, and the measurement efficiency is low. 2. Also there is contact measurement electronic gauge at present in addition, this type of utensil uses less at present, and detection efficiency has great degree to improve than traditional mechanical gauge, and structurally, all set up a contact displacement sensor to every measurement station of product, this type of utensil structure is comparatively complicated, must set up the active structure and make the product can dodge when putting the piece, and percentage table and contact sensor that these two kinds of utensils used of examining all belong to the contact measurement measuring tool, when measuring the relatively poor product of rigidity, will lead to the distortion of measured data.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem to current situation to prior art, and provide a product need not dodge when putting a, detect accurate non-contact measurement electron and examine utensil.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the non-contact measurement electronic gauge is characterized by comprising a plurality of positioning blocks, a zero calibration block, a fisheye joint, a pushing cylinder, a plurality of clamping cylinders, a laser sensor and a sensor support, wherein the zero calibration block is connected with the pushing cylinder through the fisheye joint, a buffer is arranged at the lower end of the zero calibration block and used for buffering the impact generated when the pushing cylinder pushes the zero calibration block to close, the laser sensor is fixed on the sensor support, the clamping cylinders are arranged at the upper ends of the positioning blocks, and a product to be measured is placed on the positioning blocks and clamped and positioned by the clamping cylinders.

In the non-contact measurement electronic gauge, the number of the laser sensors is three, and the laser sensors are aligned with the upper side face of the product.

Compared with the prior art, the utility model has the advantages that the measurement efficiency is improved obviously compared with the traditional mechanical checking fixture, the laser sensor has no similar contact sensor measuring head, the product does not need to be avoided when placing the part, the structure is effectively simplified compared with the contact measurement electronic checking fixture, and the reliability of the checking fixture is improved; meanwhile, the laser sensor does not apply a measuring force to the product when measuring the product, so that accurate measuring data can be obtained.
