Technical Field

[0001] This utility model belongs to the field of camshaft related technology, specifically relating to a sorting mechanism for automotive camshafts. Background Technology

[0002] Sorting of automotive cams is not necessary in all scenarios. Its core triggering logic is to avoid quality risks, ensure assembly accuracy, and adapt to different usage needs. Sorting is usually necessary or recommended in four major scenarios: "production and manufacturing, quality control, repair and replacement, and special adaptation". Repairing automotive camshafts requires inspecting the smoothness of their surfaces. Traditional inspection methods use a surface roughness tester and a machine vision inspection system, which is expensive, costing around 180,000 RMB or even more. There is a need for a lower-cost device that can assist in the inspection and sorting of defective parts to meet the needs of more businesses. To address these issues, a lower-cost sorting mechanism for automotive camshafts is proposed. Utility Model Content

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please refer to the accompanying diagrams for all instruction manuals: A sorting mechanism for automotive cams includes a base 1, automotive cam fixing components symmetrically arranged on the base 1, a sliding positioning mechanism on one side of the automotive cam fixing components on the base 1, and a sorting mechanism located between the two automotive cam fixing components on the base 1. The sorting mechanism includes a slide groove 2 located on a base 1, a slider 3 slidably connected to the slide groove 2, a screw 4 threadedly connected to the slider 3, a rotating block 5 fixedly installed on the screw 4, a sensing rod 6 inserted into the rotating block 5, a spring 7 fixedly installed between the sensing rod 6 and the rotating block 5, a ball bearing 8 installed at the upper end of the sensing rod 6, and strip-shaped through holes 9 evenly provided on the rotating block 5. A display rod 10 is slidably connected inside the strip-shaped through holes 9, and one end of the display rod 10 is fixedly connected to the sensing rod 6. A fixing plate 11 is slidably connected to the base 1 corresponding to the slide groove 2, a screw 12 is rotatably connected to the fixing plate 11, and the screw 12 is threadedly connected to the base 1. A bracket 13 is fixedly installed on one side of the base 1, a motor 14 is fixedly installed on the bracket 13, and a base plate 15 is fixedly installed on the output end of the motor 14. As described above, the two ends of the car cam to be inspected and sorted are fixed on the car cam fixing mechanism, with one end of the car cam pressing against the base plate 15. Next, the corresponding number of sliders 3 are inserted into the slide groove 2, and the sliders 3 are moved laterally to align with the position of the car cam to be inspected. Then, the rotating block 5 is rotated, and the position of the sensing rod 6 is adjusted by using the structural relationship between the screw 4 and the slider 5, so that the ball 8 can press against the car cam. Finally, the power of the motor 14 is turned on, causing the base plate 15 to rotate, which in turn drives the car cam to rotate. During the rotation, if there is wear or unevenness on the surface of the car cam, it will interact with the ball 8, causing the spring 7 below to deform. The appearance of the car cam can be clearly observed through the display rod 10.

[0020] As a technical optimization of this utility model, the automobile cam fixing mechanism includes a fixed plate 16 fixedly installed on the base 1 and an adjusting plate 17 rotatably installed on the base 1. A clamping block 18 is slidably connected between the fixed plate 16 and the adjusting plate 17. A plurality of rollers 19 are evenly provided on the clamping block 18. Springs 20 are symmetrically provided on the rollers 19. The other end of the springs 20 is fixedly connected to the clamping block 18. As can be seen from the above description, rotating the adjustment plate 17 can drive the clamping blocks 18 to move in and out, so as to achieve the fixing requirements of car cams of different sizes. The positions of the fixing plate 16 and the adjustment plate 17 can be fixed by external bolts and nuts. After the car cam is fixed, the contact roller 19 can maintain the normal rotation of the car cam.

[0021] As a technical optimization of this utility model, the sliding positioning mechanism includes a second sliding groove 21 located symmetrically fixedly installed on the base 1, and a connecting frame 22 is provided between the corresponding fixed plate 16 and the adjusting plate 17. A fixing bolt 23 is installed on the connecting frame 22, and the fixing bolt 23 is slidably connected to the second sliding groove 21. As can be seen from the above description, for car cams of different lengths, quick adjustment can be achieved by moving the connecting bracket 22 laterally and positioning it with the fixing bolt 23.

[0023] As a technical optimization of this utility model, a knob 25 is fixedly installed on one end of the screw 12 extending out of the base 1; As can be seen from the above description, the knob 25 is a regular hexagon, and the knob can be controlled by an adjustable wrench, making the fixing plate 11 more reliable.

[0024] The working process of this utility model is as follows: The two ends of the car cams to be inspected and sorted are placed on the car cam fixing mechanism for fixation, with one end of the car cam pressing against the base plate 15. Next, the corresponding number of sliders 3 are inserted into the slide groove 2, and the sliders 3 are moved laterally to align with the position of the car cam to be inspected. The knob 25 is rotated so that the fixing plate 11 presses against the sliders 3, fixing the position of the sliders 3. Then, the rotating block 5 is rotated, and the position of the sensing rod 6 is adjusted by using the structural relationship between the screw 4 and the slider 5 so that the ball 8 can press against the car cam. Finally, the power of the motor 14 is turned on, causing the base plate 15 to rotate, which in turn drives the car cam to rotate. During the rotation, if there is wear or unevenness on the surface of the car cam, it will interact with the ball 8, causing the spring 7 below to deform. The appearance of the car cam can be clearly observed through the display rod 10.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this.
