Description

Technical Field

[0001] This utility model relates to the field of automotive product measurement technology, and in particular to an automated clamping automotive product measurement fixture. Background Technology

[0002] In the automotive manufacturing industry, product quality is the lifeline of a company. The dimensional accuracy and geometric tolerances of automotive parts have a crucial impact on the performance, safety, and reliability of vehicles. The dimensional accuracy of the engine block directly affects the engine's power output and fuel economy, while the accuracy of transmission gears affects the smoothness of shifting and transmission efficiency. Traditional manual measurement and clamping methods are inefficient and prone to human error, making it difficult to meet the high-precision and high-efficiency quality control requirements of modern automotive manufacturing. As competition in the automotive industry intensifies, consumers' expectations for vehicle quality are also rising. Therefore, automakers need to continuously improve product quality to enhance market competitiveness. This has prompted automotive manufacturers to seek more advanced measuring equipment to achieve accurate measurement and strict quality control of automotive products.

[0003] The structure of an automated clamping automotive product measuring fixture includes a clamping mechanism, a drive system, a measuring system, a control system, a worktable, and a base. The automated clamping and measuring process minimizes interference from human factors. In traditional measurement, the operator's technique, force, and visual errors can all affect the measurement results. Automated fixtures, through precise mechanical structures and control systems, operate according to set standards and procedures, ensuring consistency and accuracy in each measurement. However, some fixtures have slow clamping movements, especially when frequent component changes are required for measurement. Each clamping process—opening, closing, positioning, and clamping—is time-consuming, affecting the overall measurement efficiency of automotive products. Existing technologies use clamping mechanisms designed with lever principles, which can generate large clamping forces with relatively small driving forces and achieve fast clamping speeds. However, the movement of lever mechanisms is based on the lever principle, and its trajectory is arc-shaped. In automotive product measuring fixtures, for some components requiring high-precision positioning, this arc-shaped movement can lead to a decrease in the positioning accuracy of the clamps, making it difficult to guarantee a stable clamping force under various shapes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automated clamping automotive product measuring fixture, which aims to improve the problem that the movement of the lever mechanism in the prior art is based on the lever principle and its movement trajectory is arc-shaped. In automotive product measuring fixtures, for some parts that require high-precision positioning, this arc-shaped movement will cause the positioning accuracy of the gripper to decrease, making it difficult to ensure that a stable clamping force can be provided under various shapes.

A placement platform is fixedly connected to the top center of the base plate. Automotive parts are placed on the top of the placement platform. The bottom of the first locking plate is slidably connected to the left side of the inner top of the placement platform.

A measuring mechanism is provided on the top of the base plate for measuring automotive parts.

[0007] The measuring mechanism includes a telescopic rod, the left end of which is fixedly connected to the top right end of a support plate, and the other end of which is fixedly connected to a sliding frame.

[0010] As a further description of the above technical solution:

[0011] A light bulb is fixedly connected to the top right side of the support plate, and a support platform is fixedly connected to the top left side of the support plate.

[0012] As a further description of the above technical solution:

[0013] The bottom of the support platform is rotatably connected to two rotating rings, and each rotating ring is fixedly connected to a hook at its bottom.

[0014] As a further description of the above technical solution:

The length of the car product at various angles can be understood from various angles, so as to facilitate more precise operation.

[0035] Working principle: Motor 2 4 drives the rotation of disk 5, which in turn causes short plate 1 6 to rotate. Due to the constraint of fixed block 7, short plate 1 6 moves up and down with slider 8 within fixed block 7. At this time, slider 8 moves up and down with T-shaped plate 9. Since the middle of T-shaped plate 9 is fixed, T-shaped plate 9 will start to rotate. The rotation of T-shaped plate 9 will cause short plate 2 10 and long plate 14 to rotate. The rotation of short plate 2 10 will cause locking plate 1 11 to move left and right under the constraint of the track inside the placement platform 12. Simultaneously, the rotation of the long plate 14 will cause the L-shaped plate 15 to rotate, the L-shaped plate 15 will cause the short plate 16 to rotate, and the short plate 16 will also cause the locking plate 11 to move left and right under the constraint of the track inside the placement platform 12. At this time, the relative and opposite movements of the locking plate 11 and the locking plate 2 17 are completed, thereby completing the fixation of the automotive product. In this way, the linear guide rail and slider are set at the connection part to convert the arc motion into linear motion, so that the final movement trajectory of the clamping block is a straight line, thereby improving the positioning accuracy and providing a stable clamping force.

[0036] The sliding frame 202 is slidable by pushing the telescopic rod 201. When the sliding frame 202 moves to the top of the product to be tested, the motor 203 will start to rotate with the gear 204. At this time, the toothed strip 207 on the left side of the sliding rod 206 will start to descend under the rotation of the gear 204. It will stop descending after contacting the product to be tested. Since the distance from the support sleeve 205 to the top of the placement platform 12 is fixed, the reading range of the first scale line 208 is this distance. At this time, the height of the product can be obtained by reading the first scale line 208. In this way, the measurement process can be automated by pushing the telescopic rod 201 and driving the motor. It can complete the testing of multiple products in a short time and adapt to the efficient production rhythm.
