Description

Technical Field

[0001] The utility model relates to the technical field of automated welding, in particular to a sensor nut positioning mechanism with a detection function. Background Art

[0002] In the current design of domestic automobile exhaust system tooling nut welding fixtures, we are facing increasingly stringent inspection standards and quality requirements. In order to meet these requirements, designers usually design welding tooling to be more precise and intelligent. However, this precise design often sacrifices some functions of traditional fixtures to a certain extent, such as the clamping function of the nut. In this case, the operator needs to rely more on handheld fixtures to place the nut in the welding position, which increases the complexity and risk of the operation. The short length of the nut itself may require more delicate operations when the operator is installed in place, which also increases the potential risk of pinching the hand. In view of the above problems, technicians in this field have proposed a sensor nut positioning mechanism with a detection function to solve the above problems. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides a sensor nut positioning mechanism with a detection function, aiming to improve the problem that the design of the automobile exhaust system tooling nut welding fixture in the prior art requires the operator to rely on a handheld fixture to place the nut to the welding position.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A sensor nut positioning mechanism with a detection function comprises a connecting seat, the outer side of the connecting seat is fixedly connected to a connecting shaft, the left end of the connecting shaft is fixedly connected to a positioning head, the outer side of the connecting shaft is rotatably connected to a clamping block, the right end of the connecting seat is fixedly connected to the connecting block, the inner side of the connecting block is fixedly connected to a detection sensor, the bottom end of the clamping block is fixedly connected to a spring, and the outer side of the positioning head is slidably connected to a product.

[0006] Furthermore, the top end of the connecting shaft is fixedly connected to the bottom end of the spring.

[0007] Furthermore, the pressing block is L-shaped, and the right end of the pressing block is an arc-shaped block.

[0008] Furthermore, the bottom end of the pressing block abuts against the top end of the detection sensor.

[0009] Furthermore, the exterior of the product abuts against the left end of the pressing block.

[0010] Furthermore, a protective cover is fixedly connected to the outside of the connecting block.

[0011] Furthermore, the detection sensor is arranged inside the protective cover.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, by using the connecting seat, connecting shaft, positioning head, clamping block, connecting block, detection sensor, spring and other structures in coordination with each other, the detection range can be adjusted in real time according to the change of the position of the clamping block, thereby ensuring accurate detection of the product position, improving the measurement precision and accuracy of the system, and reducing the manual operation of the operator, thereby reducing the labor intensity and risk of injury of the operator.

[0021] Specifically, the connecting seat 1 fixes the connecting shaft 2 so that the position of the connecting shaft 2 can be determined, and the connecting shaft 2 fixes the positioning head 3 so that the position of the positioning head 3 can be fixed. The clamping block 4 is L-shaped and has an arc block at the right end, and is rotatably connected to the connecting shaft 2 and abuts against the detection sensor 7. When the product 9 squeezes the left end, it will drive the right end of the clamping block 4 to start the detection sensor 7 for identification. The connecting seat 1 fixes the connecting block 5 so that the position of the connecting block 5 can be determined, and the connecting block 5 fixes the detection sensor 7 so that the detection sensor 7 can perform detection stably.

[0023] Specifically, the clamping block 4 and the connecting shaft 2 fix the spring 8, so that the spring 8 can stably perform elastic deformation, thereby stably performing reset activities, and then stably resetting the clamping block 4. Through the cooperation of the positioning head 3 and the clamping block 4, the product 9 can be tightened and fixed.

[0026] Working principle: When installing, the product 9 is clamped on the positioning head 3 through the front guide of the clamping block 4 and the internal spring 8, so that the front of the clamping block 4 changes due to the installation position of the product 9, and then the rear position of the clamping block 4 is passively changed through the pin shaft, so that the detection sensor 7 recognizes and sends a signal, thereby completing the detection of the product 9.
