Description

Technical Field

[0001] The invention relates to the technical field of automobile parts inspection, and in particular to a device for detecting the surface quality and specific dimensions of a tappet housing product. Background Art

[0002] In automotive engine hydraulic systems, the tappet housing is a critical component. The surface quality and dimensional accuracy of its working surface directly impact the hydraulic tappet's sealing, durability, and overall engine performance. Current industry standards require that the designated working surface of this part be free of surface defects such as indentations, scratches, and bumps, and that the working surface thickness be strictly controlled within a tolerance of ±0.03mm. However, existing manufacturing processes are limited by factors such as machining equipment precision, material stress and deformation, and human operational fluctuations, making it difficult to completely avoid defective products. Therefore, full inspection of finished products is essential.

[0003] Traditional detection methods mainly rely on manual work, which has the following technical problems:

[0004] 1. Surface defect detection: Inspectors need to observe the work surface with the naked eye under strong light conditions and judge defects by repeatedly adjusting the angle of the parts. Visual fatigue can easily lead to missed inspections (such as fine cracks) or misjudgments (such as reflective interference).

[0005] 2. Thickness measurement: manually place the product on the support rod, use the height digital display to measure the bottom surface of the other side of the product, and manually judge whether it is qualified based on the displayed data. The measurement operation takes a long time.

[0006] 3. Efficiency bottleneck: Single-piece inspection takes about 2-3 minutes. Based on an annual production capacity of 2 million pieces, multiple full-time inspectors are required, which has high labor costs and makes it difficult to cope with production capacity fluctuations.

[0007] Currently, some companies are trying to introduce semi-automated inspection equipment (such as fixed optical projectors), but manual loading and unloading and result judgment are still required, with an inspection speed of approximately one minute per piece, which is still insufficient to meet the needs of large-scale production. Therefore, there is an urgent need to develop a comprehensive inspection system that integrates high-precision visual inspection, automated thickness measurement, and intelligent judgment to solve the industry's long-standing quality control challenges.

The positioning rod 7 is cylindrical, and the diameter of the positioning rod 7 is smaller than the inner diameter of the head end 27. The hardness of the positioning rod 7 is lower than the hardness of the tappet shell product 26, and no scratches or scratches will be generated during the detection process.

[0046] The third telescopic mechanism 23 is arranged below the rotating material tray 4, and the telescopic axis of the third telescopic mechanism 23 is arranged vertically upward.

[0047] The technical effects achieved by this embodiment are as follows: the surface quality measuring mechanism and the thickness measuring mechanism have simple structures and can quickly and automatically detect the surface quality and thickness of the working surface of the tappet housing product 26 .

[0048] Example 3

[0049] like Figures 1 to 6 As shown, this embodiment provides another device for detecting the surface quality and specific dimensions of a tappet housing product, the structure of which includes all the contents of embodiment 2, and only the different parts are described below.

[0050] In this embodiment, the defective product rejection mechanism includes a first defective product rejection mechanism and a second defective product rejection mechanism. The first defective product rejection mechanism is arranged between the surface quality measurement mechanism and the thickness measurement mechanism, and the second defective product rejection mechanism is arranged between the thickness measurement mechanism and the qualified product collection mechanism.

[0051] In this embodiment, it should be noted that the first defective product rejection mechanism includes a second mounting seat 15, a first telescopic mechanism 6, a first scraper 19 and a first defective product channel 21.

The first defective product channel 21 is provided below the rotating material tray 4, and the feed port of the first defective product channel 21 is located directly below the first telescopic mechanism 6; the first telescopic mechanism 6 adopts a pneumatic telescopic cylinder. During the inspection process, when the surface quality measuring mechanism detects a product with unqualified surface quality, the rotating material tray 4 transports the product with unqualified surface quality to the position of the first defective product rejection mechanism. The telescopic rod of the first telescopic mechanism 6 contracts, and the first scraper 19 scrapes the product with unqualified surface quality into the first defective product channel 21 for collection, and then the first telescopic mechanism 6 automatically resets.

[0052] The second unqualified product rejection mechanism includes a fourth mounting seat 17, a second telescopic mechanism 8, a second scraper 20 and a second unqualified product channel 22. The fourth mounting seat 17 is arranged on the second bracket 12, and the second telescopic mechanism 8 is arranged on the fourth mounting seat 17. The second telescopic mechanism 8 is located above the rotating material tray 4.

The end of the telescopic rod of the second telescopic mechanism 8 is provided with a second scraper 20; the second unqualified product channel 22 is arranged below the rotating material tray 4, and the feed port of the second unqualified product channel 22 is located directly below the second telescopic mechanism 8; the second telescopic mechanism 8 adopts a pneumatic telescopic cylinder. During the inspection process, when the thickness measuring mechanism detects a product with unqualified thickness, the rotating material tray 4 transports the product with unqualified thickness to the position of the second unqualified product rejection mechanism, the telescopic rod of the second telescopic mechanism 8 contracts, and the second scraper 20 scrapes the products with unqualified surface quality into the second unqualified product channel 22 for collection, and then the second telescopic mechanism 8 automatically resets.

[0053] The technical effect achieved by this embodiment is: by setting the first unqualified product rejection mechanism and the second unqualified product rejection mechanism, products with unqualified surface quality and products with unqualified thickness can be collected respectively, which is convenient for the classification and processing of unqualified products.

[0054] Example 4

[0055] like Figures 1 to 6 As shown, this embodiment provides another device for detecting the surface quality and specific dimensions of a tappet housing product, the structure of which includes all the contents of embodiment 3, and only the different parts are described below.

[0056] In this embodiment, the qualified product collection mechanism includes a fifth mounting seat 18, a guide rod 9 and a conveyor belt 10. The fifth mounting seat 18 is arranged on the second bracket 12, and the guide rod 9 is arranged on the fifth mounting seat 18. The guide rod 9 is located above the rotating material tray 4, and the guide rod 9 is located at the edge of one side of the rotating material tray 4; the conveyor belt 10 is arranged below the rotating material tray 4, and the guide rod 9 is used to guide qualified products onto the conveyor belt 10. Specifically, a gap is provided between the guide rod 9 and the rotating material tray 4, and a guide surface is provided at the end of the guide rod 9, and the guide surface is arranged facing the corresponding part placement groove 13.

[0057] In this embodiment, it should be noted that the feeding mechanism 2 is a slide, and the slide is provided with a slide groove along its length direction. The width of the slide groove is slightly larger than the width of the tail end 28. The slide is inclined, and the height of the slide close to the vibrating material tray 1 is greater than the height of the slide close to the rotating material tray 4. A laser sensor 3 is provided in the middle of the slide. The laser sensor 3 is used to detect whether there is a push rod shell product 26 to be detected in the middle of the slide. When it is detected that there is no push rod shell product 26 to be detected in the middle of the slide, the vibrating material tray 1 is automatically started. The intermittent start of the vibrating material tray 1 can be achieved during the detection process, which is more energy-saving.

[0058] The operation process of the entire equipment is as follows: the tappet shell product 26 to be tested is placed in the vibrating material tray 1, and the vibrating material tray 1 is used to arrange the tail end of the tested product downward in the slide; the slide has a limited structure (slide) so that the tail end plane of the tested product faces a fixed direction; a sensor 3 is installed on the slide, and when the sensor detects that the slide is insufficient, it will send a signal to the vibrating material tray 1 to feed the product; after being conveyed and arranged by the slide, the tested product will slide into the rotating material tray 4, which has a specific shape of hole (parts placement slot 13) corresponding to the product , and only one product to be tested is allowed to enter at a time. The rotating material tray 4 is connected to the servo motor and performs stepping motion according to the signal; when the product to be tested is transported to the position where the camera 5 is located, the camera 5 will take a picture of the working surface of the product, judge the surface quality, and compare the picture with the database. If the comparison is qualified, it will enter the next inspection station. If the comparison is unqualified, a signal will be given to the first telescopic mechanism 6. When the unqualified product reaches the station where the first telescopic mechanism 6 is located, the cylinder moves to push the unqualified surface quality product out of the rotating material tray 4 and make it fall into the first unqualified product channel 21. When the surface quality qualified product reaches the position of the positioning rod 7, the third telescopic mechanism 23 under the rotating material tray 4 moves, lifting the tested product and making it contact with the positioning rod 7. When the tested product reaches the fixed limit position, the displacement sensor 25 identifies the height position of the blocking rod 24, and can determine the thickness of the working surface of the tappet shell product 26. If the size is qualified, it will continue to operate. If the size is unqualified, a signal will be given to the second telescopic mechanism 8. When the thickness unqualified product reaches the position of the second telescopic mechanism 8, the cylinder moves, and the unqualified product is pushed out of the rotating material tray 4 and falls into the second unqualified product channel 22. The qualified product continues to move with the rotating material tray 4. When it reaches the guide rod 9, it slides out of the rotating material tray 4 under the action of the guide rod 9 and enters the conveyor belt 10. After being conveyed, it enters the boxing stage, and the inspection is completed.
