Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and particularly relates to a device for detecting the size of automobile parts. Background Art

[0002] The measurement of the size of automobile parts mainly relies on manual use of tools such as micrometers and vernier calipers, which is inefficient and easily affected by human factors. With the development of machine vision technology, its non-contact, real-time, high-precision and other characteristics make it an ideal choice. Through steps such as image acquisition, preprocessing, feature extraction and recognition, and size calculation and determination, efficient and accurate measurement can be achieved.

[0003] The "device for detecting the production size of automobile parts" disclosed in the patent publication number "CN219869403U" includes an operating table. A first motor is fixedly installed on the outer surface of the operating table. The output end of the first motor is fixedly connected to a first rotating disk. A threaded rod is rotatably connected inside the operating table. A control mechanism is installed outside the threaded rod. A first high-definition camera is installed outside the control mechanism. An electric push rod is fixedly installed on the outer surface of the operating table. The output end of the electric push rod is rotatably connected to a second rotating disk. A first ruler rod is fixedly connected to the outer surface of the output end of the electric push rod. A second high-definition camera is installed outside the first ruler rod.

[0004] In the above patent, through the cooperation between the control mechanism and the first caliper, the control mechanism can detect the diameter of the connecting shaft, and the first caliper can measure the length of the connecting shaft, solving the problem that it is troublesome to separately detect the length and diameter when detecting the size of the connecting shaft. However, this device measures back and forth through the caliper. This repetitive work cannot be measured quickly, which will affect the user experience and is not easy to operate, which will affect the work efficiency to a certain extent. Moreover, when this device measures automobile parts, the stability of this structure is poor, which is also not conducive to the measurement quality of the parts.

[0005] Therefore, the utility model provides a device for detecting the size of automobile parts to solve the above problems. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a device for detecting the size of automobile parts, which solves the above problems.

[0007] To achieve the above object, the utility model is realized through the following technical solutions: An automobile part size detection device includes a support assembly for support. The support assembly includes a reinforcement plate, and a measurement assembly is arranged on the upper surface of the reinforcement plate. The measurement assembly includes a placement plate, and sliding grooves are formed on the upper surface of the placement plate. The number of the sliding grooves is three and they are evenly arranged. Square sliding bars are slidably connected inside all the three sliding grooves. The bottom end of each square sliding bar is fixedly connected to the top end of a telescopic rod. A spring is sleeved on the side surface of the telescopic rod. Partition plates are fixedly connected between every two adjacent springs. The end of the telescopic rod is fixedly connected to the inner side surface of the reinforcement plate.

[0008] Further, the number of the square sliding bars is three. Square connection blocks are fixedly connected between adjacent square sliding bars. Measurement plates are fixedly connected to both sides of the outer square sliding bar.

[0009] Adopting the above technical solution, the three square sliding bars ensure the stability of the measurement plates during the measurement of the device.

[0010] Further, a sliding rod is fixedly connected to the upper surface of the inner measurement plate. A limiting strip is fixedly connected to the side surface of the sliding rod. A sliding block is slidably connected to the side surfaces of the sliding rod and the limiting strip. A second laser rangefinder is fixedly connected to the right end of the sliding block.

[0011] Adopting the above technical solution, by adding the limiting strip, the direction of the sliding block can be stably maintained when the sliding block slides on the side surface of the sliding rod.

[0012] Further, a side plate is fixedly connected to the upper surface of the left end of the placement plate. A first laser rangefinder is fixedly connected to the inside of the side plate. A rotating column is movably connected to the upper right corner of the inner upper surface of the placement plate. Limiting blocks are fixedly connected to both the upper and lower ends of the rotating column. A baffle is movably connected to the side surface of the rotating column. The rotating column movably penetrates through the baffle and the placement plate.

[0013] Adopting the above technical solution, the first laser rangefinder facilitates the intuitive display of the measurement results. The baffle can be easily rotated through the movable penetration between the rotating column, the placement plate and the baffle.

[0014] Further, a bolt penetrates through the left end of the baffle and the inside of the placement plate.

[0015] Adopting the above technical solution, the position of the baffle can be fixed more flexibly through the bolt.

[0016] Furthermore, both ends of the lower surface of the reinforcement plate are fixedly connected with table legs. The bottom ends of the table legs are fixedly connected with protruding columns. The two side surfaces of the protruding columns are rotatably connected with rotating cylinders. The inner surface of the rotating cylinder is fixedly connected with a connecting rod. The right end of the connecting rod is fixedly connected with a concave plate. A threaded hole is opened on the inner wall of the concave plate, and a bolt is threadedly connected inside the threaded hole.

[0017] With the above technical solution, by setting the rotating cylinder and the concave plate, it is convenient to contract and open, and the bolt is convenient for strengthening the whole device.

[0018] Beneficial effects

[0019] The utility model provides a device for detecting the size of automobile parts. Compared with the prior art, it has the following beneficial effects:

[0020] 1. For this device for detecting the size of automobile parts, the square sliding bar and the inner measuring plate are pulled apart by the square connecting block. A part to be detected is placed between the side plate and the square connecting block, and between the square sliding bar and the inner measuring plate. Then the square sliding bar is released. The square sliding bar will closely adhere to the surface of the part to be detected, so that the first laser rangefinder can more intuitively measure the length. This avoids the situation that a large number of measurement tasks cannot be quickly completed, and the measurement result is greatly affected by the measurement angle and position, resulting in a decrease in work efficiency. By moving the square sliding bar and the measuring plate back and forth, the beneficial effects of convenient operation and rapid measurement are achieved, thus improving work efficiency.

[0021] 2. For this device for detecting the size of automobile parts, after the concave plate is turned over to the ground through the rotating cylinder, the device is fixed to the ground through the bolt and the threaded hole. This avoids the deviation of the measurement data caused by the instability of the measurement device, which affects the accuracy of the part size and further affects the assembly quality and performance of the whole vehicle. The beneficial effect that the size detection of this device can ensure that the size accuracy of each part meets the design requirements, thereby improving the overall manufacturing quality is realized.
