Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically to a clamping tool for assembling automobile parts. Background Technology

[0002] Efficient and precise vehicle production relies heavily on advanced technology. In this field, end effectors, with their intelligent and high-precision features, are becoming indispensable tools in the automotive assembly process. As a crucial component of industrial robots, end effectors directly participate in the final stages of automobile production.

[0003] In the assembly process, end effectors are used to precisely grip and place parts according to instructions, ensuring a smooth and accurate assembly flow. Their application is becoming increasingly widespread on automotive production lines.

[0004] In the production process of new energy vehicle batteries, the processing and assembly of the battery lower casing is a crucial step. Currently, traditional clamping fixtures have certain shortcomings when clamping the lower casing of new energy vehicle batteries. Firstly, existing clamping fixtures cannot flip the clamped battery lower casing during use. Therefore, when installing the lower casing of new energy vehicle batteries, it is usually necessary to manually place the lower casing on the fixture bracket, then clamp it with the fixture bracket and lift it to the bottom of the vehicle for installation. This increases the workload and intensity of workers, while also reducing the installation efficiency of the clamping fixture for the lower casing of automotive batteries. Utility Model Content

The limiting rod 5, the collar 501 and the base plate 502 can limit the support frame 3, further improving the stability of the support frame 3 during the lifting process.

[0023] As a technical optimization of this utility model, the drive mechanism includes gear I 202, and gear II 203 is meshed with the side surface of gear I 202. One side surface of gear I 202 and gear II 203 is fixedly connected to one end of lead screw 204. A servo motor 2 is fixedly connected to the other side surface of gear I 202. The side surface of servo motor 2 is fixedly connected to the front surface of moving seat 1 through limiting plate 201. The height of support frame 3 can be easily adjusted through the drive mechanism, thus making it convenient for workers to install the lower battery housing at the bottom of the car.

[0024] As a technical optimization of this utility model, a clamping base plate 702 is symmetrically fixedly connected to the inner surface of the clamping side plate 7, and a support plate 703 is symmetrically fixedly connected to the upper surface of the clamping side plate 7.

[0027] In use, the support frame 3 is first moved to the side of the battery lower housing placement bracket by the movable seat 1, aligning the support frame 3 with the battery lower housing. Then, the operator pushes the push rod 6 to move the clamping side plate 7 inside the support frame 3 outwards. At this point, the clamping side plate 7 will be located at both ends of the battery lower housing. The operator then clamps and fixes the battery lower housing using the clamping screw 701 and the clamping base plate 702. The operator then pulls the push rod 6 to return the clamping side plate 7 to its original position. Afterwards, the operator observes the opening orientation of the battery lower housing. If the opening is facing downwards, the operator needs to activate the reduction motor 401 in the adjustment mechanism. 1. The worm gear 402 drives the worm wheel 4 to rotate. At this time, the worm wheel 4 drives the lower battery housing to flip through the rotating shaft and the clamping side plate 7 until the opening of the lower battery housing faces upward. Then, the operator operates the moving seat 1 to move under the car and align it with the battery installed under the car. Then, the servo motor 2 in the drive mechanism is started. At this time, the servo motor 2 will drive the lead screw 204 to rotate through gear I 202 and gear II 203. The lead screw 204 will lift the support frame 3 through the top plate 206 and the slider 205. After the lower battery housing inside the clamping side plate 7 covers the battery, the operator can install the lower battery housing on the bottom of the car with bolts to protect the battery on the car.
