[0026] Refer to Figure 1 、 Figure 4 and Figure 5, an embodiment provided by the present utility model: a symmetry detection device for mechanical part production, comprising a detection platform 1, an installation frame 2 is fixedly connected to the upper part of the detection platform 1, a placement rack 21 is fixedly connected to the outer rear side of the detection platform 1, a cleaning component 22 is arranged on the upper part of the placement rack 21, and the cleaning component 22 is used to clean the dust attached to the outside of the mechanical part. A fixed block 5 is fixedly connected to the inside of the detection platform 1, a mounting table 13 is rotatably connected to the middle of the fixed block 5, a rotating shaft 7 is rotatably connected to the inside of the fixed block 5, a gear 6 is fixedly connected to the outside of the rotating shaft 7, an electric push rod 9 is fixedly connected to the outside of the fixed block 5, a moving block 10 is fixedly connected to the output end of the electric push rod 9, a slider 11 is fixedly connected to the lower part of the moving block 10, a rack plate 8 is fixedly connected to the outside of the moving block 10, the rack plate 8 is engaged with the gear 6, the rack plate 8 is slidably connected to the inside of the fixed block 5 and the detection platform 1, the top of the rotating shaft 7 is fixedly connected to the mounting table 13, a limiting block 14 is fixedly connected to the outside of the mounting table 13, a cylinder 24 is fixedly connected to the inside of the mounting table 13, a mounting shell 26 is fixedly connected to the upper part of the mounting table 13, a guiding block 25 is fixedly connected to the output end of the cylinder 24, the guiding block 25 is slidably connected to the inside of the mounting shell 26, hinge blocks 16 are fixedly connected to the outer periphery of the guiding block 25, arc-shaped clamping plates 18 are arranged around the upper part of the mounting table 13, bumps 19 are fixedly connected to the lower parts of the plurality of arc-shaped clamping plates 18, one end of a rotating plate 17 is rotatably connected to the inside of the plurality of hinge blocks 16, and the other end of the plurality of rotating plates 17 is rotatably connected to the inside of the plurality of arc-shaped clamping plates 18. A chute 12 is formed in the inside of the detection platform 1, the slider 11 is slidably connected to the inside of the chute 12, a limiting groove 15 is formed in the inside of the fixed block 5, the limiting block 14 is slidably connected to the inside of the limiting groove 15, grooves 20 are formed around the upper part of the mounting table 13, and the plurality of bumps 19 are slidably connected to the inside of the plurality of grooves 20. Through holes 27 are formed around the inside of the mounting shell 26, and the plurality of rotating plates 17 are slidably connected to the inside of the plurality of through holes 27. A cross plate 3 is fixedly connected to the right side inside the mounting frame 2, and a laser sensor 4 is installed inside the cross plate 3.
[0027] When performing symmetry detection on mechanical parts, first, the mechanical part is sleeved outside the four arc-shaped clamping plates 18. After starting the cylinder 24, the cylinder 24 pushes the guide block 25 fixed to the output end downward. The movement of the guide block 25 drives the synchronous movement of a plurality of hinge blocks 16 fixed around the outside. During the movement of these hinge blocks 16, they drive the movement of the rotating plate 17 rotatably connected inside. The movement of the rotating plate 17 will, through the cooperation of the four convex blocks 19, cause the four arc-shaped clamping plates 18 connected to the other end to expand outwards. Through the outward movement of the four arc-shaped clamping plates 18, the mechanical part is firmly fixed on the detection platform 1. When the mechanical part is fixed, when performing symmetry detection, start the electric push rod 9. The electric push rod 9 drives the movement of the moving block 10 fixed to its output end, and the movement of the moving block 10 further drives the movement of the rack plate 8 fixed to its outside. The movement of the rack plate 8 causes the gear 6 meshed with its outside to start rotating. The rotation of the gear 6 is transmitted to the rotating shaft 7 fixed inside, causing the rotating shaft 7 to start rotating. The rotation of the rotating shaft 7 drives the mounting table 13 fixed to the top to rotate inside the fixed block 5. During the rotation of the mounting table 13, it drives the mechanical part fixed to its outside to rotate together. It realizes that when performing symmetry detection on mechanical parts, it is convenient to fix the mechanical part and also convenient to rotate the mechanical part during the detection process. Since the process of fixing the mechanical part is completely automated and the operator does not need to fix it manually, this eliminates the error problem caused by manual fixing by the operator. The automatic fixing ensures the consistency of the position and angle of the parts for each detection, thus greatly improving the detection accuracy and consistency. When performing symmetry detection on mechanical parts, the external contour of the part is continuously scanned by the laser sensor 4 to collect high-precision surface data.
[0028] Refer to Figure 1 , Figure 2 and Figure 3 , the cleaning assembly 22 includes a filter box 2201, the filter box 2201 is fixedly connected to the upper part of the placement rack 21, a filter plate 2203 is inserted inside the filter box 2201, an air inlet 2204 is fixedly connected to the left side outside the filter box 2201, a blower 2202 is installed on the right side inside the filter box 2201, a delivery pipe 2205 is fixedly connected to the right side outside the filter box 2201, the other end of the delivery pipe 2205 penetrates through the inside of the mounting rack 2 and is fixedly connected to an air outlet 2206, and mounting rods 23 are fixedly connected to both sides outside the air outlet 2206, and the tops of the two mounting rods 23 are fixedly connected to both sides outside the mounting rack 2.
[0029] Before detecting mechanical parts, start the blower 2202 to suck external air through the air inlet 2204. The air first enters the filter box 2201, where a filter plate 2203 is installed inside. The filter plate 2203 can effectively filter dust and other tiny particles in the air. The air treated by the filter plate 2203 is purified and then transmitted through the conveying pipe 2205. The purified air passes through the air outlet 2206, thus reaching the air outlet 2206 and finally discharging the air. During this process, the purified air is guided to the upper area of the detection platform 1 to clean the mechanical parts placed on the platform. In this way, the dust and impurities attached to the surface of the mechanical parts can be completely removed, ensuring that the sensor can read the real surface data of the parts during the detection process. This pre-cleaning process greatly improves the accuracy and reliability of the detection of mechanical parts. The cleaning step not only helps to eliminate external interferences that may affect the detection results but also extends the service life of the detection equipment. The air outlet 2206 can be fixed conveniently by setting the mounting rod 23.
[0030] Working principle: When detecting the symmetry of mechanical parts, first, put the mechanical part outside the four arc-shaped clamping plates 18, and then start the cylinder 24. The cylinder 24 drives the guide block 25 fixed to the output end to move downward. The movement of the guide block 25 drives the hinge blocks 16 fixed around the outside to move synchronously. The movement of multiple hinge blocks 16 drives the rotating plates 17 rotatably connected inside to move. The movement of multiple rotating plates 17 drives the four arc-shaped clamping plates 18 rotating at the other end to move around through the cooperation of the four bumps 19. Fix the mechanical part by moving the four arc-shaped clamping plates 18 around. Then, when detecting the symmetry, start the electric push rod 9. The electric push rod 9 drives the moving block 10 fixed to the output end to move. The movement of the moving block 10 drives the rack plate 8 fixed outside to move. The movement of the rack plate 8 drives the gear 6 engaged outside to rotate. The rotation of the gear 6 drives the rotating shaft 7 fixed inside to rotate. The rotation of the rotating shaft 7 drives the mounting table 13 fixed to the top to rotate inside the fixed block 5. When the mounting table 13 rotates, it drives the mechanical part fixed outside to rotate, realizing that when detecting the symmetry of the mechanical part, it is convenient to fix the mechanical part and also convenient to rotate the mechanical part during detection. When fixing the mechanical part, there is no need for the operator to manually fix the mechanical part, which can eliminate the error caused by manual fixing by the operator and ensure that the position and angle of the parts to be detected each time are consistent, thereby improving the detection accuracy and consistency. Before detecting the mechanical part, start the blower 2202, inhale the external air through the air inlet 2204, then filter the inhaled air through the filter plate 2203 inserted inside the filter box 2201, and then convey the filtered air through the delivery pipe 2205. Finally, discharge the inhaled air through the air outlet 2206 to clean the mechanical part placed on the upper part of the detection platform 1, realizing that before detecting the symmetry of the mechanical part, it is convenient to clean the dust attached to the outside of the mechanical part. Cleaning the outside of the part can ensure that the sensor reads the real surface data of the part, thereby improving the detection accuracy.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
