Abstract
Description
Technical Field
[0001] The invention relates to the technical field of small-aperture mold roundness detection, and in particular to a small-aperture mold roundness detection tool and a detection method. Background Art
[0002] In the field of copper alloy tube and bar processing, extrusion, drawing and other methods are often used to process and deform the material. Then the dimensional accuracy of the small-aperture mold used directly affects the dimensional tolerance, roundness, etc. of the product. How to check the dimensional tolerance and roundness of the small-aperture mold is a problem. With the development of science and technology, various testing instruments, such as three-coordinate measuring machines, have appeared on the market one after another, but the equipment is expensive, and one unit requires 300,000 to 500,000 yuan. For medium and micro enterprises, the equipment investment cost is high. In the conventional testing environment without three coordinates, only calipers and micrometers, calipers and micrometers can be used for large-aperture and small-aperture molds. Multi-point measurement, thereby obtaining the aperture roundness of the small-aperture mold. However, for small-aperture molds, calipers and micrometers are limited by the measuring claws and cannot be measured. Using calipers and micrometers to measure will also cause slight damage to the measuring surface, and there will be errors in multi-point measurement. In addition, because the small-aperture molds used have arc chamfers, diameter changes, taper angles and other requirements, it increases the difficulty of detection. Therefore, the present invention, from the perspective of practicality and low cost, invents a small-aperture mold roundness detection tooling and method. Summary of the invention
[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a small-aperture mold roundness detection tool and detection method.
[0004] In order to achieve the above object, the present invention adopts the following technical solutions:
[0005] A small-aperture mold roundness detection tool and detection method, comprising a base, a fixed bin is provided on the top of the base, and a light source is installed on the top of the fixed bin. A fixed position is provided on the top of the base, and a small-aperture mold is provided on the top of the fixed position. A projection board is provided on the top of the base away from the light source, and a marking line is provided on the surface of the projection board close to the light source. S1: Make parts according to drawings and assemble them. S2: Put the small-aperture mold to be inspected in a fixed position and check whether it is placed in place. S3: Turn on the light source and adjust the centering. If only one bright dot can be seen on the projection board, it means that the centering is completed. S4: Adjust the projection board so that the bright dot fits any marking line. S5: Check whether the bright dot deviates from the marking line. If the aperture fits the marking line, it means that the roundness is qualified; if the aperture does not fit the marking line partially, it means that the roundness is unqualified; if the aperture does not fit the marking line at all, it means that the projection board or the light source is not adjusted properly. The roundness of the small-aperture mold can be detected by setting the light source, the projection board, and the marking line.
[0006] The beneficial effects of the present invention are:
[0007] The present invention can greatly reduce the roundness detection cost of small-aperture molds by setting up light sources, projection plates, and marking lines. While reducing the cost, the detection difficulty is also reduced synchronously to ensure that it is quickly determined whether the roundness of the small-aperture mold has deviation.

[0012] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0013] Reference Figure 1-Figure 2A small-aperture mold roundness detection tool and detection method, including a base 1, a fixed bin 4 is provided on the top of the base 1, and a light source 401 is installed on the top of the fixed bin 4. A fixed position 3 is provided on the top of the base 1, and a small-aperture mold 301 is provided on the top of the fixed position 3. By setting the fixed position 3, the small-aperture mold 301 can be placed stably. A projection plate 2 is provided on the top of the base 1 away from the light source 401, and a marking line 201 is provided on the surface of the projection plate 2 close to the light source 401. S1: Make parts according to the drawings and assemble them. S2: Place the small-aperture mold 301 to be inspected in the fixed position 3 and check whether it is placed in place. S3: Turn on the light source 401 and adjust the centering. If only one bright dot can be seen on the projection plate 2, it means that the centering is completed. S4: Adjust the projection plate 2 so that the bright dot fits any marking line 201. S5: Check whether the bright dot deviates from the marking line 201. If the aperture fits the marking line 201, it means that the roundness is qualified; if the aperture does not fit the marking line 201 partially, it means that the roundness is unqualified; if the aperture does not fit the marking line 201 at all, it means that the projection plate 2 or the light source 401 is not adjusted properly. By setting the light source 401, the projection plate 2 and the marking line 201, the roundness of the small-aperture mold 301 can be detected.
[0014] Working principle: When the present invention is used, firstly, parts are made according to the drawings, and then assembled. The specific assembly method is as follows: Figure 1 As shown, during the assembly process, the marking line 201 and the light source 401 can be adjusted. After the assembly is completed, the small aperture mold 301 to be inspected is placed in the fixed position 3 and checked to see if it is in place. The specific placement is as follows Figure 2 As shown, after the small-aperture mold 301 is placed correctly, the light source 401 can be turned on and adjusted for centering. If only one bright dot can be seen on the projection plate 2, it means that the centering is completed. Then adjust the projection plate 2 so that the bright dot fits any marking line 201, and observe whether the bright dot deviates from the marking line 201. If the aperture fits the marking line 201, it means that the roundness is qualified; if the aperture does not fit the marking line 201 partially, it means that the roundness is unqualified; if the aperture does not fit the marking line 201 at all, it means that the projection plate 2 or the light source 401 is not adjusted properly.
