Embodiment 1

[0047] Such as figure 1 , figure 2 As shown, a constant velocity universal joint rod length and cavity bottom thickness measuring machine includes a base 1 on which a measuring mandrel 2 for positioning a workpiece 100 to be measured is fixed, and on the base 1 is also fixed There is a thickness measuring mechanism 3 for measuring the thickness of the cavity bottom of the workpiece 100 to be measured, and a length measuring mechanism 4 for measuring the rod length of the workpiece 100 to be measured is fixed on the thickness measuring mechanism 3;

[0048] Such as figure 1 , figure 2As shown, the thickness measuring mechanism 3 includes a measuring ring 5 that interferes with the workpiece 100 to be measured, and the base 1 is fixed with a driver 6 that drives the measuring ring 5 to move along the axial direction of the measuring mandrel 2. The thickness The measuring mechanism 3 also includes a thickness measuring instrument 7 for detecting the displacement distance of ...

Embodiment 2

[0063] This embodiment is a further limitation of Embodiment 1.

[0064] Such as figure 1 , figure 2 As shown, the thickness measuring instrument 7 is a first grating ruler, and the first grating ruler includes a first scale grating 15 fixed on the base 1 and a first indicator grating fixed on the measuring ring 5, The first scale grating 15 can be fixed on the base 1 through a detachable or non-detachable connection. In order to improve the fixing performance of the first scale grating 15, the first scale grating 15 can be made to lean against the driver 6, and the first scale The grating 15 is fixed to the driver 6 so that the first scale grating 15 is securely fixed.

[0065] The length measuring instrument 12 is a second grating ruler, and the second grating ruler includes a second scale grating 16 fixed on the measuring ring 5 and a second indicator grating fixed on the slider 9 .

[0066] Both the first grating ruler and the second grating ruler are common grating ru...

Embodiment 3

[0074] The display 13 includes a display screen and a processor, and the thickness measuring instrument 7 and the length measuring instrument 12 all communicate with the processor, and the processor processes the parameters measured by the thickness measuring instrument 7 and the length measuring instrument 12 Controls the display display.

[0075] The processor is a common processor in the prior art, and its main function is to process the parameters measured by the length measuring instrument 12 and the thickness measuring instrument 7, such as simple conversion and the like.

Abstract

The invention provides a rod length and cavity bottom thickness measuring machine of a constant-speed universal joint, and aims at solving the technical problems that measurement of the constant-speeduniversal joint has large errors and is inconvenient to operate in the prior art. According to the measuring machine, a measuring core rod and a thickness measuring mechanism is arranged on a pedestal, a length measuring mechanism is arranged on the thickness measuring mechanism, and a display displays parameters measured by the thickness measuring mechanism and the length measuring mechanism. Compared with measurement via a vernier caliper, the measuring efficiency is higher, the length and thickness are measured automatically by the measuring machine, errors caused by manual measurement canbe avoided, and the measuring precision of a workpiece is improved greatly.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a constant velocity universal joint rod length and cavity bottom thickness measuring machine, which belongs to the field of measuring tools. Background technique [0002] After precision forging of constant velocity universal joints, in order to prevent dimensional deviation due to equipment and other factors, it is necessary to take one piece from every other batch of products to measure the rod length and cavity bottom thickness of the precision forged blank. Ensure that the dimensions of forgings of the same batch are within the controllable range. At present, vernier calipers and depth gauges are used to measure the length of the rod and the thickness of the cavity bottom after precision forging of the universal joint. Depth, take the difference between the two as the value of the cavity bottom thickness. [0003] After precision forging of constant velocity universal joint, the surface ...
