Description

Opening-adjustable bushing clamping mechanism

Technical Field

The utility model relates to a bush detects auxiliary device, concretely relates to bush fixture with adjustable opening.

Background

In the production and assembly of automobile parts, the bush is an indispensable part, and because the guide sleeve is produced in large batches, the bush is measured according to the number of produced pieces, the bush belongs to mass production, and special production equipment and special detection equipment are required. Wherein have certain size requirement to its hole in the bush production process, whether satisfy the requirement in order to detect the bush internal diameter, all can adopt the needle gauge to fill in and detect, but this requires that operating personnel fills in one by one and detects, and detection efficiency is low.

To the condition that artifical detection efficiency is low, some producers have researched and developed automatic testing machine, detect through workstation cooperation clamping device and expert no-go gage, but clamping device on the current test machine all is fixed dimension, when carrying out not unidimensional bush detection, need carry out clamping device's change, lead to the cost-push, it is loaded down with trivial details to change moreover, has reduced production efficiency.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model discloses a solve prior art not enough, provide a bush fixture with adjustable opening, realize the regulation of centre gripping opening size to the bush of the multiple size of adaptation reduces the cost, improves production efficiency.

The utility model adopts the technical proposal that: the utility model provides a bush fixture with adjustable opening installs on the workstation of bush test machine, includes the base, U type guide post and centre gripping slip subassembly, wherein: an adjusting chute is recessed in the surface of the base, a test hole is formed in the center of the adjusting chute, and through notches are formed in the two ends of the adjusting chute; two free ends of the U-shaped guide post penetrate through the notch of the base, and a through inclined guide groove is formed in each free end; the clamping sliding assemblies are placed on the surface of the adjusting sliding groove, symmetrically distributed on two sides of the test hole and comprise clamping blocks and two sliding blocks connected with the clamping blocks, the two sliding blocks are distributed on the front side and the rear side of the guide column, guide rods are connected between the two sliding blocks, and the guide rods are inserted into the inclined guide grooves; the U-shaped guide post moves up and down through a bottom cylinder driver, and the inclined guide groove is matched with the guide rod to enable the sliding block to drive the clamping blocks to move horizontally, so that the opening size between the two clamping blocks is adjusted.

Preferably, the clamping surface of the clamping block is a V-shaped opening, and the upper edge of the opening is inclined outwards to form a flaring.

Preferably, the surfaces of two free ends of the U-shaped guide post are provided with threaded holes penetrating through the guide groove, and the guide rod is locked by matching with the screw rod.

Preferably, a plurality of reset springs are arranged between the base and the U-shaped guide rod, and two ends of each reset spring are clamped in the base and the U-shaped guide rod respectively.

Has the advantages that: the utility model discloses a bush fixture with adjustable opening has following beneficial effect: through guide post cooperation bottom cylinder realization upper and lower flexible control, through slope guide way cooperation guide bar with the side-to-side movement of up-and-down motion change for the slider to realize open-ended regulation, adopt simple mechanical structure to realize the regulation of opening size, with the bush of the multiple size of adaptation, reduce the cost, improve production efficiency.

FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;

fig. 3 is a sectional view taken along line B-B in fig. 1.

In the figure: the test device comprises a base 1, a 2-U-shaped guide post, a 3-adjusting groove, a 4-testing hole, a 5-notch, a 6-inclined guide groove, a 7-threaded hole, an 8-clamping block, a 9-sliding block, a 10-guide rod, an 11-V-shaped opening, a 12-flaring and a 13-reset spring.

Detailed Description

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

As shown in fig. 1-3, the utility model discloses a bush fixture with adjustable opening installs on the workstation of bush test machine, including base 1, U type guide post 2, centre gripping slip subassembly, the pedestal mounting is on the workstation, and its upper surface indent has adjustment tank 3, and this adjustment tank transversely sets up, and test hole 4 has been seted up to its central point, and the bush is located directly over the test hole, and the setting of test hole is convenient for lead to no-go gage to test the bush, the notch 5 that link up is seted up at the adjustment tank both ends, changes the notch and is the installation for the time guide post, the both free ends of U type guide post alternate in the notch, and be equipped with the slope guide way 6 that runs through around in the free end, and the screw hole 7 that runs through to the slope guide way is located to the tip of free end simultaneously.

Centre gripping slip subassembly is placed in the adjustment tank, and the symmetric distribution is in the test hole both sides, centre gripping slip subassembly includes grip block 8 and two sliders 9, and two slider parallel distribution are connected through the guide bar 10 of interlude in the slope guide way each other at the front and back face of U type guide post free end, grip block and two slider fixed connection, V type opening 11 are personally submitted to its centre gripping, and V type opening upper edge leans out and forms flaring 12.
