Description

Technical Field

[0001] This utility model relates to the field of steering column quality inspection technology, and in particular to a quality inspection device for automobile steering column production. Background Technology

[0002] Quality inspection, also known as "technical inspection," is a quality management method that uses certain testing methods and inspection techniques to determine the quality characteristics of a product and compares the results with the prescribed quality standards to determine whether a product or a batch of products is qualified or unqualified. In the production of automotive steering columns, quality inspection is required to ensure the safety of vehicle use.

[0003] Chinese Patent CN217654927U discloses a quality inspection device for automobile steering column production. This device uses a torque sensor to drive a connecting shaft to rotate, causing a fixed sleeve to apply torque to the steering column. However, while solving the problem, this quality inspection device for automobile steering column production has the following drawbacks:

[0004] Its fixed plate is fixedly connected to the base, which means that the position of the connecting plate cannot be adjusted. It can only be used to test steering columns of a fixed length, which has great limitations. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a quality inspection device for the production of automotive steering columns, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of this utility model provides a quality inspection device for automobile steering column production, including a base plate. The top of the base plate has a sliding groove and a T-shaped groove. A slider is slidably connected inside the sliding groove, and a connecting plate is fixedly connected to the top of the slider. A T-shaped block is slidably connected inside the T-shaped groove. A fixing plate is fixedly connected to the side of the connecting plate, and a fixing bolt is threaded onto the surface of the fixing plate. A connecting column is fixedly connected to one side of the connecting plate, and a C-shaped block is fixedly connected to one end of the connecting column. An adjusting bolt is threaded onto the inside of the C-shaped block, and a clamping plate is rotatably fixed to one end of the adjusting bolt.

[0008] Preferably, in any of the above solutions, a bearing is fixedly installed inside the clamping plate, and the bearing prevents the clamping plate from rotating synchronously with the adjusting bolt.

[0009] Preferably, in any of the above embodiments, a motor is provided on the top of the base plate, and a torque sensor is fixedly connected to the output shaft of the motor. The motor and the torque sensor cooperate to detect the applied force.

[0010] Preferably, one end of the output shaft of the motor is fixedly connected to a connecting sleeve, which facilitates connection with the steering column.

[0011] Preferably, as described in any of the above schemes, a pad is fixedly connected to the top of the base plate, which increases the height of the motor so that it is on the same horizontal line as the C-shaped block.

[0012] Preferably, one side of the clamping plate is fixedly connected to a rubber pad, which can protect the steering column and prevent it from being damaged by clamping.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. The slider moves within the groove, causing the connecting plate and C-block to move. The distance is adjustable, making it suitable for testing steering columns of different lengths, thus expanding its applicability and improving its flexibility.

[0015] 2. After the connecting plate is moved to the required position, tighten the fixing bolts on the fixing plate so that one end of it contacts the base plate to fix the connecting plate. The T-shaped block slides in the T-slot. During the test, when the connecting plate is subjected to torque, the T-shaped block can share the force on the connecting plate.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
