Abstract

The invention discloses a drawn cup wall thickness detection device which comprises a base and is characterized in that: a fixing plate is arranged on the base; a central spindle is arranged below the fixing plate; the middle part of the fixing plate is connected with a measurement rod through a track; a guide sleeve is arranged on the measurement rod; a dial gauge stand is arranged at the upper part of the fixing plate; a dial gauge is arranged on the dial gauge stand; a tension spring is connected between the guide sleeve and the fixing plate; the top of the guide sleeve is connected with the bottom of the dial gauge; the bottom of the guide sleeve is arc-shaped; to measure a product, the measurement rod is moved upwards to lift up the guide sleeve, the product is sleeved on the central spindle, the measurement rod is released, and the guide sleeve is compacted on the outer surface of the product through the tension of the spring; then the product is rotated for one circle; if the thickness of the product is not uniform, the thickness of a single section and the change amount of the product can be read from the dial gauge through the up-down movement of the guide sleeve; and the bottom of the guide sleeve is arc-shaped, and the vertex of the arc is in contact with the outer surface of the product so as to ensure the accuracy of the measured value.

Description

A kind of drawn cup Wall Thickness Testing Device
Technical field
The present invention relates to bearing detecting instrument field, especially relate to a kind of drawn cup Wall Thickness Testing Device.
Background technology
At present, drawn cup at stretching process because the bottom is uneven, because of there not being datum plane; Can't use existing bearing instrument to detect wall thickness and wall thickness variation; The general wall thickness micrometer gauge that adopts detects wall thickness and wall thickness variation, and the problem of its existence is: detection efficiency is slow, detects breakpoint in the single plane and detects; Not necessarily detect product actual maximum point and smallest point, therefore have certain measuring errors.
Summary of the invention
Technical matters to be solved by this invention provides a kind of wall thickness of drawn cup inter process and the drawn cup Wall Thickness Testing Device of wall thickness variation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of drawn cup Wall Thickness Testing Device, comprise base, and it is characterized in that: said base is provided with fixed head; Said fixed head below is provided with mandrel; Said fixed head middle part is connected with sounding rod through track, and said sounding rod is provided with orienting sleeve, and said fixed head top is provided with dial framework; Said dial framework is provided with clock gauge; Be connected with extension spring between said orienting sleeve and the fixed head, said orienting sleeve top links to each other with the clock gauge bottom, and said orienting sleeve bottom is circular arc type.
After adopting said structure, be characterized in: when product needed is measured, sounding rod is upwards moved; Orienting sleeve is lifted, product is enclosed within on the mandrel, sounding rod is decontroled; Pulling force through extension spring is pressed on product external surfaces with orienting sleeve, then product is rotated a circle; Can not make clock gauge read the value of thickness and variation on the single cross section of product through moving up and down of orienting sleeve first like the product thickness; The orienting sleeve bottom is circular arc type, and the summit of circular arc is contacted with product external surfaces, has guaranteed the accuracy of measured value.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. base, 2. fixed head, 3. mandrel, 4. sounding rod, 5. orienting sleeve, 6. dial framework, 7. clock gauge, 8. extension spring.
Embodiment
A kind of drawn cup Wall Thickness Testing Device shown in Figure 1 comprises base 1, it is characterized in that: said base 1 is provided with fixed head 2; Said fixed head 2 belows are provided with mandrel 3; Said fixed head 2 middle parts are connected with sounding rod 4 through track, and said sounding rod 4 is provided with orienting sleeve 5, and said fixed head 2 tops are provided with dial framework 6; Said dial framework 6 is provided with clock gauge 7; Be connected with extension spring 8 between said orienting sleeve 5 and the fixed head 2, said orienting sleeve 5 tops link to each other with clock gauge 7 bottoms, and said orienting sleeve 5 bottoms are circular arc type.
After adopting said structure, be characterized in: when product needed is measured, sounding rod 4 is upwards moved; Orienting sleeve 5 is lifted, product is enclosed within on the mandrel 3, sounding rod 4 is decontroled; Through the pulling force of extension spring 8, orienting sleeve 5 is pressed on product external surfaces, then product is rotated a circle; Can not make clock gauge 7 read the value of thickness and variation on the single cross section of product through moving up and down of orienting sleeve 5 first like the product thickness; Orienting sleeve 5 bottoms are circular arc type, and the summit of circular arc is contacted with product external surfaces, have guaranteed the accuracy of measured value.
