Description

Technical Field

[0001] The utility model relates to the field of bearing manufacturing, in particular to a tool for quickly detecting the collapse size of screw knurling. Background Art

[0002] In the prior art, two-dimensional imagers and microscopes are used to detect knurling size. During the production process, the two-dimensional imager has limited resources and can only perform small batch inspections (one piece every four hours). The microscope can only perform visual comparisons with standard parts, and its accuracy is relatively poor.

[0003] A single machine can produce 110 sets of products every four hours, and product quality cannot be effectively controlled using two-dimensional imagers and microscopes.

Inspection can be carried out at any time, and the inspection time for a single product is 30 seconds. The collapse size of the knurl can be quickly inspected to ensure product quality.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following structure, the description of the well-known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] like Figure 1 The tool shown is for quickly detecting the collapse size of screw knurling, including a positioning mechanism 10, which includes a V-shaped positioning groove 11, and the screw knurling section 110 of the screw 100 to be detected is placed in the direction of the inner side of the V-shaped positioning groove 11.

[0022] The lead screw connecting section 120 of the lead screw 100 to be tested is placed on the outside of the V-shaped positioning groove 11 .

[0023] A bracket 20 is provided at the rear end of the positioning mechanism 10, and an adjustment section 30 is provided at the upper end of the bracket 20. The adjustment section 30 is an adjustment column with one end fixed to the periphery of the magnifying glass structure 40. The adjustment column extends into the adjustment column mounting groove 21 at the upper end of the bracket, and is locked after the extension distance of the adjustment column is controlled by the locking piece 22.

[0024] Specifically, the bracket 20 includes a lower mounting frame 201 , one end of which is fixed to the rear side of the positioning mechanism 10 , a mounting vertical frame 202 is arranged on the lower mounting frame 201 , and an upper mounting frame 203 is arranged on the mounting vertical frame 202 .

[0025] The adjusting column specifically extends into the adjusting column mounting groove 21 of the upper mounting frame 203 .

[0026] A magnifying glass structure 40 is disposed at the end of the adjusting section 30 , and a scale 50 is disposed on the magnifying glass structure 40 . The scale 50 is used to read the collapsed size data of the lead screw knurl 130 received by the magnifying glass structure 40 .

[0027] Because of the above structure, the working principle of the utility model is:

[0028] First, we use standard parts for calibration so that the size of the standard parts corresponds to the size of the scale. When we subsequently inspect the product, if the knurling collapse size is smaller than the size of the scale, it is judged as qualified, and if it exceeds the size of the scale, it is judged as NG. The main improvement is that we used two-dimensional imagers and microscopes for inspection before. The two-dimensional imager has low inspection efficiency, and the microscope can only rely on employees to visually judge by comparing with standard parts, and the accuracy cannot be guaranteed.

[0029] The specific steps are as follows:

[0030] 1. Make a standard part for the collapse of the screw knurling (if the collapse size is 0.4mm, make a standard part with a collapse of 0.4mm).

[0031] 2. Place the threaded end of the standard part on the positioning mechanism.

[0032] 3. Rotate the standard part so that the side with the collapsed mark faces upward (aligned with the magnifying glass structure).

[0033] 4. Record the position of the collapse mark on the scale of the magnifying glass structure (for example, if the knurl collapse of 0.4mm is aligned with scale 1, use the pointer on the scale to move to that position to mark it).

[0034] 5. Normally inspect the product. During the inspection, place one end of the product thread end on the positioning mechanism of the knurl collapse detection, rotate the screw, if the knurl collapse part 131 exceeds the scale 1 of the scale, it is judged as NG, and if it is within the scale 1 of the scale, it is judged as qualified.

[0035] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above.

[0036] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected. The scope of protection of the present invention shall be defined by the attached claims and their equivalents.
