Description

A utensil is examined to height for supporting lugs on casing

Technical Field

The utility model relates to the field of product size detection, in particular to a height gauge for a support lug on a shell.

Background

For mass-produced workpiece products, where the dimensions of some critical locations are of great concern to customers, we need to be the manufacturer to ensure dimensional accuracy for 100% measurement determinations. However, it is difficult to measure products in batches by using a proper gauge for products with unstable dimensions of the reference surface.

Since the position of the lugs on the housing is a mounting datum point for the assembly of the compressor, the height of the lugs on the housing must be ensured. However, since the size of each shell has a certain error, no stable reference point exists, and when the conventional caliper block is used for testing, the problems of low efficiency, poor testing precision and the like exist. However, for products with unstable reference surface dimensions, it is difficult to measure the products in batches using a suitable gauge.

Detailed Description

As shown in fig. 1 and 2, a height gauge for lugs on a housing comprises a base plate 1, and a group of support legs, not shown in the drawings, are uniformly distributed at the bottom of the base plate 1.

The vertical column 2 is vertically connected to the position, close to the corner, of the upper surface of the bottom plate 1, the sliding rail 3 which is vertically distributed is connected to the outer wall of the vertical column 2, and the sliding block 4 which can move up and down through external force is arranged on the sliding rail 3. The limiting plate 12 is arranged at the top end of the upright post 2, the limiting plate 12 is of a circular diameter larger than the diameter of the upright post 2, and when the sliding block 4 moves to the highest point of the sliding rail 3, the sliding block is contacted with the limiting plate 12, so that limiting fit with the limiting plate 12 is formed.

The slider 4 is connected with a measuring rack 5, and the measuring rack 5 is connected with a dial indicator 6 for measurement through a connecting seat 5 c. The measuring frame 5 at the lower end of the dial indicator 6 is provided with a mounting groove 5a, and the groove body of the mounting groove 5a is provided with a through hole 5b. The measuring head 6a is arranged, the measuring head 6a comprises a rod-shaped part a, one end of the rod-shaped part a is connected with a limiting block b, the rod-shaped part is sleeved on the upper end and the lower end of the through hole 5b in a penetrating mode and extends out of the through hole 5b, and the limiting block b is in limiting fit with the bottom of the mounting groove 5a, so that the measuring head 6a is prevented from falling out of the mounting groove 5 a.

The detection probe 6b at the lower end of the dial indicator 6 passes through the connecting seat 5c to be inserted into the mounting groove 5a and is coaxially distributed with the measurement head 6a, the detection probe 6b inserted into the mounting groove 5a is sleeved with a spring 6c, the upper end of the spring 6c is contacted with the connecting seat 5c, and the lower end is contacted with the limiting block b. The lower end of the measuring frame 5 at the side of the lower end of the measuring head 6a also extends downward to form a reference block 5d.

A fixed clamping groove 8 which forms limit plug-in connection with a shell 7 to be measured is connected to the bottom plate 1 at one side of the upright post 2. The fixing clip groove 8 includes a riser 8a distributed in an L shape, and a cover plate 8b in an L shape is connected to the riser 8a, thereby forming one L-shaped fixing clip groove 8.

A limiting screw rod 10 is arranged on the bottom plate 1 on one side of the sliding rail 3 in a penetrating way, and the diameter of the corresponding through hole on the bottom plate 1 is larger than that of the limiting screw rod 10 in a straight descending way. One end of the limit screw 10 is connected with the slide block 4. A reset spring 9 is sleeved on the rod body of the limit screw 10 between the bottom plate 1 and the sliding block 4, the upper end of the reset spring 9 is contacted with the sliding block 4, and the lower end is contacted with the bottom plate 1. The cap head 10a of the limit screw 10 is positioned below the bottom plate 1. The support legs have a height greater than the movable travel of the cap 10 a.

The working process comprises the following steps:

firstly, preparing a test block with a step, then placing the test block below a slide block, wherein the lower end of a measuring head 6a can be pressed on the step, a limit block b can be immobilized under the support of the step when the slide block moves downwards, and when the slide block is continuously pressed down so that a reference block 5d contacts the upper surface of the step, a detection probe 6b of a dial indicator 6 can also contact a limit block b, so that the dial indicator 6 gives a standard value. This value is the standard height of the lugs 11 in the acceptable housing.

And then removing the test block, inserting the shell 7 to be detected into the fixed clamping groove 8, manually pressing down the sliding block to contact the upper surface of the shell 7 through the reference block 5d, enabling the lower end of the measuring head 6a to contact the upper surface of the supporting lug 11 on the upper surface of the shell, and comparing standard values obtained when the test block is measured before, so as to judge whether the height of the supporting lug 11 on the shell 7 is a qualified product.
