Problems solved by technology
However, since the clamping plate is used once, the tapered pin will perform two actions: taking out and inserting, which is inconvenient to use; moreover, the tapered pin will be worn due to repeated friction during use, resulting in poorer positioning accuracy. It is getting lower and lower, and because the tapered pins limit the angle of the clamp, it can only be used for the measurement of a set angle. When the measurement environment changes and the angle of the clamp needs to be changed, it needs to be remade Checking fixtures that meet angle requirements

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Figure 1 to Figure 6 The reference numerals in are: clamping plate 1; second positioning plane 11; second limit limit surface 12; avoidance gap 13; support 2; Limit limit surface 32; lock nut 4; adjustment nut 5; elastic body 6; positioning pin 7.
[0025] like Figure 1 to Figure 6 As shown, a clamp inspection tool for measuring the section and surface of a part includes a clamp 1 for measuring the section and surface of a part, a positioning pin 7 and a support 2, and one end of the positioning pin 7 is connected to the support 2 Fixed connection, the clamping plate 1 and the support 2 are stacked, which can increase the contact area between the clamping plate 1 and the support 2, avoid the shaking or deflection of the clamping plate 1, and improve the measurement precision.
[0026] like Figure 1 to Figure 6 As shown, the clamp...

The invention relates to a snap-gauge detection tool for measuring section and surface of a part. The invention provides the snap-gauge detection tool for measuring the section and the surface of the part. The snap-gauge detection tool comprises a snap-gauge for measuring the section and the surface of the part, a locating pin and a support; one end of the locating pin is fixedly connected with the support; the snap-gauge is laminated with the support; the snap-gauge is rotatably connected with the support through the locating pin; the other end of the locating pin is connected with an adjusting nut via a thread; an elastic body is clamped between the adjusting nut and the snap-gauge; a limiting block is arranged on the support; a first locating plane is arranged on the limiting block, and a second locating plane is arranged on the snap-gauge. The snap-gauge detection tool has the beneficial effects that the snap-gauge can stop at any angle through the adjusting nut and the elastic body; the snap-gauge detection tool can be suitable for measurement with different angle demands on the snap-gauge, does not generate abrasion, and is high in measurement accuracy; a reference plane is built by virtue of the first locating plane and the second locating plane, and the snap-gauge detection tool is higher in measurement accuracy and more convenient to use.
Description
technical field [0001] The invention relates to a checking tool, in particular to a clamping checking tool used for measuring the section and surface of a part among the checking tools. Background technique [0002] Checking fixtures are simple tools used in industrial production to control various dimensions of products (such as aperture, space dimensions, etc.), improve production efficiency and control quality, and are suitable for mass-produced products. Due to the different detection purposes, the inspection tools usually include two categories. One is the measurement-type inspection tool, which is mainly used to measure the size and position of the product; the other is the functional inspection tool, which is mainly used to measure the product. shape parameter. [0003] In the production process of automobile body parts, in order to ensure the assembly quality of products, it is usually necessary to use functional inspection tools to measure the shape parameters of a...
