Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection technology, and in particular to an anti-deviation inspection fixture for automotive parts. Background Technology

[0002] Precise positioning and installation of automotive parts are crucial for ensuring the quality and performance of the entire vehicle during manufacturing and assembly. As the automotive industry moves towards higher precision and efficiency, anti-misalignment detection of parts has become an important means of guaranteeing assembly quality. Anti-misalignment detection fixtures, as specialized inspection tools, are mainly used to detect whether parts have shifted position during assembly or processing, ensuring that the installation position of parts meets design requirements, thereby avoiding assembly errors, functional failures, and even safety hazards caused by part misalignment. With the increasingly complex structures of automotive components and the diversification of part sizes and shapes, the design of anti-misalignment detection fixtures faces greater challenges, requiring a balance between versatility and specialization to ensure adaptability to the inspection needs of different part models.

[0003] A search revealed Chinese Patent Publication No. CN116202421A, which discloses an automotive parts inspection fixture, comprising: a frame, a side frame fixedly mounted on the side of the frame, a transfer mechanism and an inspection mechanism one mounted on the top of the frame, the inspection mechanism one being equipped with a feeding mechanism; and an inspection mechanism two mounted on the top of the side frame; the inspection mechanism two has the same structure as the inspection mechanism one. In this invention, the automotive parts to be inspected are placed in the feeding cylinder of the feeding mechanism, and motor four is started to rotate. The rotation of motor four drives both the first and second strainer discs to rotate simultaneously, causing the automotive parts to first fall onto the surface of strainer disc one, and then onto the surface of inspection mechanism one. Motor two rotates in the opposite direction, loosening the automotive parts held in the first strainer disc, and they fall onto inspection mechanism two for data acquisition and inspection processing on the other side of the automotive parts. The above-mentioned automotive parts inspection fixture has the following shortcomings:

[0004] Although the above-mentioned device completes the double-sided inspection of automotive parts, the parts may shift during the transport process before inspection. This reduces the inspection efficiency and affects the inspection results when the parts are transported to the inspection equipment. Therefore, there is an urgent need for an anti-shift inspection fixture for automotive parts. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixture for detecting the misalignment of automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The mounting plate has four fixed feet at its bottom corners, and the bottom of the mounting plate is equipped with an anti-deviation mechanism to correct the automotive parts during transportation.

[0009] The moving mechanism, which is fixedly installed on both sides of the anti-deviation mechanism, is used to contact and push the automotive parts;

[0010] The conveying mechanism, fixed to the top center of the mounting plate on both sides, is used to convey automotive parts for inspection.

[0011] As a further embodiment of this utility model: the anti-deviation mechanism includes a guide rod, a rotating plate, a first rotating shaft, a second rotating shaft, a fixing block, and a cylinder;

[0021] Compared with the prior art, this utility model provides a fixture for detecting the misalignment of automotive parts, which has the following advantages:

[0022] This automotive parts anti-deviation inspection fixture uses a starting cylinder to drive the U-shaped frame to move horizontally, causing the rotating plate to rotate around the axis. This pulls two guide rods to swing, causing the two U-shaped frames to move synchronously towards the center of the mounting plate. The U-shaped frames slide within the guide rails, and the push plate at the top U-end moves synchronously. When the automotive parts are transported by the conveying mechanism, the push plate can correct the parts, solving the problem of the inspection effect being affected by the positional deviation of the automotive parts during the transport process. This ensures the inspection quality of automotive parts and improves its inspection efficiency.

[0023] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] A type of automotive parts anti-deviation detection fixture, such as Figure 1-5 As shown, the mounting plate 2 is provided. The four corners of the bottom outer wall of the mounting plate 2 are respectively fixed with support feet 1 by bolts. The bottom of the mounting plate 2 is provided with an anti-deviation mechanism 3. The two moving ends of the anti-deviation mechanism 3 are equipped with moving mechanisms 5. The top middle two sides of the mounting plate 2 are fixedly installed with conveying mechanisms 4.

[0033] To address the issue of positional shifts affecting inspection results during the transport of automotive parts, such as... Figure 3 As shown, the anti-deviation mechanism 3 includes a guide rod 301, a rotating plate 302, a first rotating shaft 303, a second rotating shaft 304, a fixing block 305, and a cylinder 306. The top end of the first rotating shaft 303 is rotatably connected to the bottom center of the mounting plate 2 via a bearing. The rotating plate 302 is threaded onto the bottom circumference of the first rotating shaft 303. The two guide rods 301 are rotatably connected to the bottom outer walls of both ends of the rotating plate 302. The end of each guide rod 301 away from the rotating plate 302 is rotatably connected to the bottom of the conveying mechanism 4 via the second rotating shaft 304. The fixing block 305 is fixedly installed at one corner of the bottom of the conveying mechanism 4. The cylinder 306 is fixedly connected to one side of the bottom of the mounting plate 2 via a support plate. The piston end of the cylinder 306 is fixedly connected to one side of the fixing block 305. The model of the cylinder 306 is CXSM6-10.

[0034] The moving mechanism 5 includes a U-shaped frame 501, a guide rail 502, a limiting plate 503, a push plate 504, and fixing holes 505. The guide rail 502 is fixedly installed on the outer walls of the four corners of the bottom of the mounting plate 2. The limiting plate 503 is fixedly connected to one end of the guide rail 502. The inner side of each U-shaped frame 501 is limited and slidably connected to the guide rail 502. The two ends of the push plate 504 are fixedly installed on the two ends of the U-shape of the U-shaped frame 501. The fixing holes 505 are equally spaced on one side of the push plate 504. One end of the push plate 504 has an L-shaped structure.

[0035] During operation, cylinder 306 is activated, causing the U-shaped frame 501 to move horizontally. At this time, the rotating plate 302 rotates around the rotating shaft 303. The rotating plate 302 pulls the two guide rods 301 to swing, so that the two U-shaped frames 501 move towards the center of the mounting plate 2 simultaneously. During this process, the U-shaped frame 501 slides in the guide rail 502, and the moving U-shaped frame 501 drives the push plate 504 at its top U-end to move synchronously. Thus, when the automotive parts are transported through the conveying mechanism 4, they can be corrected by the push plate 504 at the top of the U-shaped frame 501, ensuring the quality of the inspection and improving the efficiency of the automotive parts inspection.

[0036] To facilitate the stable transport of automotive parts, such as Figure 5 As shown, the conveying mechanism 4 includes a fixed plate 401, a conveying roller 402, mounting holes 403, and a mounting shaft 404. The fixed plate 401 is fixedly installed on both sides of the top of the mounting plate 2. The mounting holes 403 are respectively opened on both sides of the bottom of the fixed plate 401, and are fixedly connected to both sides of the mounting plate 2 by bolts in the mounting holes 403. The mounting shaft 404 is fixedly connected to the top of the fixed plate 401 at equal intervals. The conveying roller 402 is rotatably connected to the circumference of the mounting shaft 404. It is used for the stable conveying of automotive parts.

[0037] Working principle:

[0038] The fixing plate 401 is fixedly installed on the top two sides by bolts, and the conveying roller 402 is fixedly installed on the circumference of the mounting shaft 404 by threads. When the car parts are conveyed on the conveying roller 402 to the two push plates 504, the cylinder 306 is activated, and the cylinder 306 drives the U-shaped frame 501 to move horizontally.

[0039] At this time, the rotating plate 302 rotates around the rotating shaft 303. The rotating plate 302 pulls the two guide rods 301 to swing, so that the two U-shaped frames 501 move towards the center of the mounting plate 2 at the same time. During this period, the U-shaped frame 501 slides in the guide rail 502, and the moving U-shaped frame 501 drives the push plate 504 at its top U end to move synchronously. Thus, when the car parts are transported by the conveying mechanism 4, they can be corrected by the push plate 504 at the top of the U-shaped frame 501, which facilitates the subsequent inspection of the car parts.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
