Abstract

The invention provides a tractor spring testing fixture, relates to the field of spring testing fixtures, and aims to the problem that no testing fixture capable of simultaneously detecting tractor spring free arc height, half-chord length and center bolt symmetry exists at present. The tractor spring testing fixture comprises a support. A bottom plate is fixed to the top of the support, a fixed end base block is arranged on the left portion of the bottom plate, and a movable end base block is arranged on the right portion. A V-shaped groove is formed in the fixed end base block, and bolts arearranged on the fixed end base block and the movable end base block; the base is fixed in the middle of the bottom plate, a ruler base is fixed at the top of the base and provided with a front vertical plate and a rear vertical plate, and guide columns on the fixing blocks are inserted into holes of the front vertical plate and the rear vertical plate. A protruding block of the sliding block is inserted into a groove of the fixing block, a sliding sleeve is arranged at the top of the fixing block, and a symmetry degree measuring ruler is arranged in the sliding sleeve. The sliding block is provided with a semi-chord length measuring ruler sliding rail, the semi-chord length measuring ruler base and the semi-chord length measuring ruler sliding rail are installed in a sliding fit mode, andthe semi-chord length measuring ruler is fixed to the semi-chord length measuring ruler base. The tractor spring testing fixture has the advantage of simultaneously detecting the free arc height, thesemi-chord length and the central bolt symmetry degree of the tractor spring.

Description

Technical field:

[0001] The invention relates to the field of spring inspection tools, in particular to a inspection tool capable of detecting the free arc height, half-chord length and central bolt symmetry of tractor springs. Background technique:

[0002] The detection of the free arc height of the tractor spring is a mandatory item. The current method is generally to measure with a ruler or a tape measure, which has large detection errors, low accuracy, time-consuming and labor-intensive work, and labor-intensive work; the half-chord length value of the tractor spring was previously measured. And the symmetry of the center bolt (that is, whether the center bolt is on the longitudinal centerline of the leaf spring) is not tested, but at present, many users request to detect the value of the half-chord length and the symmetry of the center bolt, so it is urgent to design a device that can simultaneously Checking tools for testing tractor spring free arc height, half chord ...

Embodiment Construction

[0019] Combine below Figure 1-3 The present invention is further described;

[0020] It includes a bracket 1, a base plate 2 fixed on the top of the bracket, two fixed end base blocks 3 are fixed on the upper surface of the base plate, and two movable end base blocks 4 are fixed on the right portion of the upper surface of the base plate; the two fixed end bases Both the block and the two movable end blocks are arranged one behind the other;

[0021] The upper surfaces of the two fixed-end base blocks are provided with V-shaped grooves 5 extending downward, and the two fixed-end base blocks directly below the V-shaped grooves are provided with threaded holes, and the bolts are installed in the threaded holes. The heads of the two bolts are on the outside of the two fixed-end base blocks, and the screws are exposed from the inside of the two fixed-end base blocks, that is, the screw ends of the two bolts are opposite;

[0022] The two movable end base blocks are provided wit...
