Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection technology, and in particular to an automotive parts position measurement tool. Background Technology

[0002] The precision of automotive parts is related to the connection quality of each part and the quality of the car itself. For example, after machining holes in some brackets, mounting plates and other parts on a car, the position of the holes needs to be checked to ensure the accuracy of the hole positions of the automotive parts leaving the factory.

[0003] In the prior art, positional gauges can be used to detect the positional accuracy of holes on automotive parts. The gauge is equipped with a detection hole and a detection pin. By using the detection pin to cooperate with the detection hole and the hole on the part, the accuracy of the hole position can be verified. However, automotive parts such as brackets and mounting plates often have multiple or even dozens of holes. The matching gauge needs to be equipped with multiple or even dozens of independent detection pins. If any of the independent detection pins is lost, it will affect the use of the entire gauge.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "provided with" should be interpreted broadly. For example, the object "provided with" can be a part of the main body, or it can be separately arranged from the main body and connected to it. This connection can be detachable or non-detachable. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will be further described in detail below with reference to the embodiments.

[0025] Specific embodiment 1 of the automotive parts position gauge provided by this utility model:

[0026] Please see Figure 1-2 The automotive parts position measurement fixture includes a base 1, several detection pins 3 and flexible connectors 4. The base 1 is provided with several detection holes 2 that correspond one-to-one with the detection pins 3. Each detection hole 2 is provided with a cylindrical bushing 5. The detection pins 3 are inserted into the inner side of the bushing 5. The inner diameter of the bushing 5 is the same as the inner diameter of the hole on the corresponding automotive parts being measured.

[0027] In this embodiment, the automotive component is a transmission bracket 9. The testing process is as follows: The machined-hole transmission bracket 9 is placed on the base 1, so that the holes on the transmission bracket 9 initially align with the holes on the base 1. Two detection pins 3 are selected as positioning pins, passing through the holes on the transmission bracket 9 and inserting the ends of the positioning detection pins 3 into the bushings 5 ​​inside the corresponding detection holes 2. This achieves the positioning of the transmission bracket 9 on the base 1. Then, the remaining detection pins 3 are inserted one by one. If all detection pins 3 can pass through the holes in the transmission bracket 9 and insert into the bushings 5 ​​inside the corresponding detection holes 2, it indicates that the position of the holes on the transmission bracket 9 is accurate. Conversely, if the detection pins 3 cannot pass through the holes in the transmission bracket 9 and insert into the corresponding bushings 5, it indicates that the hole position is inaccurate.

[0028] In this embodiment, there are ten detection holes 2, bushings 5 ​​and detection pins 3, which are divided into ten groups; eight groups are vertical and two groups are horizontal.

[0029] To prevent individual detection pins 3 from being lost, all detection pins 3 are connected to flexible connectors 4. In this embodiment, the flexible connector 4 is a rope, and the detection pins 3 are connected to the rope at intervals. The length of the rope between adjacent detection pins 3 should be greater than the distance between adjacent detection pins 3 after positioning, so that the detection pins 3 can be easily inserted and matched, and the rope can be avoided from interfering with the insertion detection.

[0030] In this embodiment, the detection pin 3 and the flexible connector 4 are both fixedly connected; the rope is made of steel wire rope, and the rope and the flexible connector 4 are connected by welding.

[0031] In this embodiment, the ends of the rope are connected by rope buckles 6 to form a loop.

[0032] Specific embodiment 2 of the automotive parts position gauge provided by this utility model:

[0033] The difference between this embodiment and embodiment 1 is that in embodiment 1, the detection pin 3 and the flexible connector 4 are fixedly connected by welding. The advantage of this is that it enhances the overall integrity and prevents the loss of individual detection pins 3. The disadvantage is that it is not easy to replace the overall structure after individual detection pins 3 are damaged.

[0034] Therefore, in this embodiment, please refer to Figure 3 One side of the flexible connector 4 is connected to a bolt 7 corresponding to each detection pin 3. Each detection pin 3 has an internally threaded blind hole 8 at its end that is threaded to the bolt 7. Thus, while the detection pins 3 are connected as a whole, they are detachably connected to the flexible connector 4 via the bolts 7, allowing for quick replacement if the detection pin 3 is damaged. In other embodiments, the outer side of the detection pin 3 near the internally threaded blind hole 8 is machined into a hexagonal shape, making it easy to rotate the detection pin 3 with a wrench.

[0035] Specific embodiment 3 of the automotive parts position gauge provided by this utility model:

[0036] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the flexible connector 4 is a rope, while in this embodiment, please refer to... Figure 4 The flexible connector 4 is the net body, specifically, the net body is a flexible steel wire rope net, and the detection pin 3 is connected to one side of the net body.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
