Abstract
The utility model discloses a drawn cup wall thickness testing device which comprises a base. The drawn cup wall thickness testing device is characterized in that a fixing plate is arranged on the base; a core shaft is arranged below the fixing plate; the middle part of the fixing plate is connected with a measuring rod through a rail; a guide sleeve is arranged on the measuring rod; a dial gauge stand is arranged on 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; and the bottom of the guide sleeve is of an arc type. When a product needs to be measured, the measuring rod is moved upward, and the guide sleeve is raised; the product is sheathed on the core shaft; the measuring rod is released; with the tension force of the tension spring, the guide sleeve presses on the outer surface of the product; and then the product is turned a circle. If the product has different thickness, the guide sleeve moves up and down to enable the dial gauge to read the values of the thickness and variation of a single section of the product. The bottom of the guide sleeve is of an arc type, and the peak of the arc contacts the outer surface of the product, thus the accuracy of measurement values is ensured.
Description
Technical field
The utility model relates to bearing detecting instrument field, especially relates 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
The utility model technical matters to be solved provides a kind of wall thickness of drawn cup inter process and the drawn cup Wall Thickness Testing Device of wall thickness variation.
The utility model solves the technical scheme that its technical matters adopted: 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 utility model is further specified.
Fig. 1 is the structural representation of the utility model.
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.
