Problems solved by technology

The disadvantage of this method is that the workload of the measurement personnel is heavy, the human measurement error has a great impact on the test results, and the measurement efficiency is low. Moreover, the processed products have a low assembly pass rate and poor interchangeability. In order to solve Product processing and measurement bottlenecks, for this reason, an automatic detection device for valve core and valve sleeve parameters is proposed

Embodiment Construction

[0010] refer to figure 1 . In the embodiment described below, the device for quickly detecting the shape and size parameters of the cylindrical excircle includes: a servo motor bracket fixed on the working platform, a counter-symmetrical servo motor tip, and a coaxial clamping workpiece with a shift fork 2 top support. The measured workpiece 2 and the circular grating 4 are rigidly connected. Install the valve core or valve sleeve on the dial sleeve, and at the same time, the other end of the workpiece 2 with the shift fork is placed on the top of the high-precision front shaft system 13, put the shift rod on the dial sleeve into the shift fork, and the shift fork On the top of the high-precision circular grating 4, the servo motor is arranged in the motor drive box 9, and the anti-interference cover 8 is covered. Turn the hand wheel to make the tip of the tail reach the proper position, use the manual gear to operate the initial aiming, and then use the automatic gear to s...

Abstract

The invention discloses a device for rapidly detecting size parameters of a cylinder type excircle shape, and aims at providing the rapid detection device simple in structure, high in measuring efficiency and capable of improving the measuring precision. A CCD camera (5) whose lens just faces a clamped detected workpiece (2) is arranged over the clamped detected workpiece, the CCD camera (5) collects images of the clamped detected workpiece which is driven by a servo motor to rotate, the collected calibration position size of each groove is converted into a digital signal, the digital signal is transmitted to a circular grating (4) fixed on a main shaft of the servo motor, the angular displacement of the detected workpiece, namely a moving object, is obtained, a linear array photosensitive tube calculates the position size of each groove via a computer image processing software system input by a reading head device, parameters including the width, the position accuracy and the verticality of the calibration groove of the detected workpiece are displayed and printed. The device can be used to overcome the disadvantages that errors of manual measurement influence test results a lot and cause low measuring efficiency.

Description

technical field [0001] The invention relates to a device for quickly detecting the shape and size parameters of the outer circle of a cylindrical part, especially the method for adding a plurality of indexing grooves on the outer circle of a cylindrical part to measure the width of the groove, the position of the groove and the verticality. Rapid detection device. Background technique [0002] Cylindrical excircle shapes contain many dimensional parameter elements, and their structural shapes are different, and the coaxiality error requirements proposed in the design are also different. The detection technology in mechanical processing can be divided into online detection, processing room detection and post-processing detection according to its different methods. The inspection items in machining mainly include: the size, shape and surface roughness of the workpiece. In the field of mechanical processing, valve sleeves and valve cores are a common structural type in mechan...
