Description

Technical Field

[0001] The invention relates to a detection system, in particular to a system for quickly detecting the parallelism of a product height surface. Background Art

[0002] At present, for the test of high parallelism of parts, three-coordinate measuring instruments or high-precision height gauges are often used to randomly check several points on the measured surface to determine the spatial position of the side surface. It can be seen that unless the side surface is a mirror surface in the strict sense, the defined surface is not the actual installation surface. The actual installation surface is determined by the three highest points on the side surface. The points randomly measured by the above instruments cannot be exactly the highest points on the side surface. The measured results must have errors. At the same time, this measurement method is laborious and time-consuming, and the efficiency is very low. It is impossible to conduct a full inspection of batch parts.

[0003] In addition, similar products need to determine whether the parallelism of two or more surfaces at different heights is qualified, and also need to be measured in three coordinates. The defect is that the product cannot be quickly tested like a caliper during the production process. Because the detection takes a long time, the production line is suspended. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a system for quickly detecting the parallelism of the height surface of a product.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A system for quickly detecting the parallelism of the height surface of a product, comprising a check fixture floor, a reference block, and a measuring block.

[0007] The reference blocks and measuring blocks are distributed on the inspection fixture floor according to the shape of the product to be inspected.

[0008] The reference block is provided with a fixing mechanism.

[0009] A fixing mechanism is arranged on the measuring block.

[0010] The inspection tool floor is provided with mounting holes.

[0011] The upper surface of the inspection fixture floor is evenly distributed with horizontal and vertical dividing lines.

[0012] The inspection fixture floor is a movable structure, and both the upper and lower surfaces are kept level.

[0013] The height of the reference block is adjusted by a three-coordinate measuring machine.

[0014] A magnet is embedded in the upper surface of the reference block.

[0015] Buckle assemblies are provided on both sides of the upper surface of the measuring block.

[0016] On the inspection fixture floor, first make a reference block with one surface of the product as the reference, and make height blocks with the other surfaces to be measured according to a standard value. Finally, use a gap gauge or a go / no-go gauge to measure or judge whether the product is qualified.

[0017] Compared with the prior art, the present invention can quickly detect the parallelism of two or more surfaces of different heights of a product without the need for a three-coordinate measuring instrument by adding reference blocks and measuring blocks, and can complete the detection around the machine to ensure the continuity of the production line.

[0020] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present invention.

[0021] Example

[0022] A system for quickly detecting the parallelism of the height surface of a product, the structure of which is as follows Figure 1 As shown, it includes components such as a test fixture floor 1, a reference block 2, and a measuring block 3. The test fixture floor 1 is provided with mounting holes, and the reference block 2 and the measuring block 3 are distributed on the test fixture floor 1 according to the shape of the product to be tested. In addition, the test fixture floor 1 can also be evenly distributed with horizontal and vertical dividing lines to facilitate adjustment or calibration of the installation position. The test fixture floor is a movable structure, and the upper and lower surfaces are kept level. The test can be completed around the machine to ensure the continuity of the production line.

[0023] The height of the reference block 2 and the measuring block 3 are installed on the inspection fixture floor 1 after being debugged by the three-dimensional coordinate measuring machine. A magnet is embedded in the upper surface of the reference block 2 to ensure that the product will not shake on the reference block. Buckle components are provided on both sides of the upper surface of the measuring block 3.

[0024] On the inspection fixture floor, first make a reference block with one surface of the product as the reference, and make height blocks for other surfaces to be measured according to a standard value. Finally, use a gap gauge or a go / no-go gauge to measure or judge whether the product is qualified. Specifically, place the product on reference block 2 according to the position of reference block 2 and measuring block 3 relative to the reference surface, and then use a feeler gauge to measure whether the parallelism of the product relative to the reference surface meets the requirements of the drawing. If it does, use a feeler gauge to measure or use a go / no-go gauge to determine whether the distance from other surfaces to the measuring block meets the design requirements. The above measurement or judgment method can quickly determine whether the product meets the requirements of the drawing so that the next step can be taken.

[0025] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
