Embodiment Construction

[0014] The present invention will be described in further detail below.

[0015] See also figure 1 , figure 2 , image 3 , Figure 4 .

[0016] The detection tooling of the present invention includes a base 1, a guide post 2, a spring 3, a guide sleeve 4, a rib 5, a frame 6, a dial indicator 7, a fastening screw 8, a limit rod 9, a screw 10, and a pile code 11.

[0017] When the present invention is in use, first three dial indicators 7 are fastened in three through holes of the frame 6 with screws 8, and the stop bar 9 is screwed into the threaded hole of the frame 6, and the dial indicator is set on the basis of the standard block gauge. The sub-meter 7 is pre-compressed half a turn and adjusted to zero position. At this time, the limit rod 9 is also in contact with a step surface of the size to be measured, and the size of the standard block gauge is consistent with the nominal size between the three surfaces to be measured.

[0018] The spring 3 of the present invent...

Abstract

The invention belongs to the detection technology and relates to a fast measuring device for a multiple step sizes of a mechanical processing part. Especially, original multiple detections are realized through one measurement. Three dial indicators [7] and a limit rod [9] are fixed at the frame [6] of the measuring tool, with the corporation of a guide column [2], a spring [3], a guide sleeve [4] and a weight [11], the frame [6] moves up and down, the measuring heads of the dial indicators [7] act on the three steps of a measured part [12], the measuring data can be rapidly and visually read, and the fast, accurate and efficient measurement is realized.

Description

technical field [0001] The invention belongs to detection technology, and relates to a device for quickly measuring the dimensions of multiple steps of machined parts. Background technique [0002] In mechanical processing, it is often necessary to detect the multi-step size of parts. Usually, the height ruler is used to measure multiple times, and the data is read on the engraved line each time. This measurement method has large visual errors, poor detection accuracy, and low detection efficiency. It is not suitable for the fast and economical requirements of batch production. Contents of the invention [0003] The purpose of the present invention is to design and manufacture a measuring fixture for three-step dimensions in machined parts, so as to improve the measurement accuracy and improve the measurement efficiency. [0004] The technical solution of the present invention is: a multi-step dimension one-time measurement inspection tool, which is characterized in that ...
