Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a tooling for inspecting the dimensions of automotive parts. Background Technology

[0002] Automotive parts are an important component of automobiles. Different parts have different dimensions and requirements. To ensure better use of these parts later on, their height is usually inspected during production. However, traditional methods for inspecting part height mostly rely on manual measurement by operators. This method is not only inefficient but also susceptible to human factors such as visual fatigue, errors in the use of measuring tools, and reading deviations, leading to inaccurate measurement results.

[0003] Therefore, it is necessary to invent a tooling for inspecting the dimensions of automotive parts to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for inspecting the dimensions of automotive parts, in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for inspecting the dimensions of automotive parts, including a workbench, a controller mounted on the front of the workbench, a fixed bracket mounted on the top of the workbench, a placement area at the center of the top of the workbench, a detection component positioned directly below the fixed bracket and above the placement area, the detection component including a detection pressure plate, a loading rack mounted on one side of the top of the detection pressure plate, an infrared rangefinder mounted at one end of the loading rack with the detection end of the infrared rangefinder facing downwards, a first electric push rod mounted at the center of the top of the fixed bracket, the working end of the first electric push rod extending below the fixed bracket and fixedly connected to the top of the detection pressure plate, a pressure sensor embedded at the center of the bottom of the detection pressure plate, and the infrared rangefinder, the first electric push rod, and the pressure sensor all electrically connected to the controller.

[0006] By integrating an infrared rangefinder, a first electric push rod, and a pressure sensor, the height of automotive parts is automatically measured. Utilizing the real-time feedback mechanism of the pressure sensor, the push rod stops immediately and triggers infrared ranging when the pressure plate contacts the workpiece, avoiding human error and significantly improving measurement accuracy and efficiency.

[0007] Preferably, the detection end of the infrared rangefinder and the detection end of the pressure sensor are both at the same height as the bottom of the detection plate. The detection end of the infrared rangefinder can emit infrared rays towards the top of the workbench and receive the reflected signals. Then, the infrared rangefinder will calculate the height of the car parts based on the time difference of the signals and display the measurement results on the controller.

[0008] The infrared rangefinder and the pressure sensor are kept at the same height to ensure that when the pressure sensor triggers the infrared rangefinder, the length measured by the infrared rangefinder is exactly the height of the car part.

[0009] Preferably, the controller can control the first electric push rod to drive the detection pressure plate to perform lifting and lowering operations. The first electric push rod can drive the detection pressure plate to squeeze the top of the automotive parts. When the pressure sensor detects pressure, it will send a signal to the controller, and then the controller will immediately stop the action of the electric push rod and simultaneously start the infrared rangefinder to measure the height of the automotive parts.

[0010] Preferably, a light-shielding plate is installed on the back and on each of the left and right sides of the fixed bracket. The light-shielding plate is used to block excessive light and avoid interference from strong light environment on infrared rangefinder.

[0011] Preferably, the fixed bracket has an operating door installed on its front, and a transparent observation window is installed in the middle of the operating door.

[0012] The fixed support features an operating door and a transparent observation window on the front, which facilitates the placement and removal of workpieces by operators, while also allowing for real-time observation of the testing process.

[0013] Preferably, the top of the workbench is provided with two clamping components, which are located on both sides of the placement area.

[0014] By clamping and fixing the automotive parts with two clamping components, it is ensured that the automotive parts will not move or tilt during the inspection process, thereby avoiding measurement errors caused by changes in the position of the workpiece and improving the reliability of the inspection.

[0015] Preferably, the detection component includes a second electric push rod, the working end of which is equipped with a limit plate, and the clamping surface of the limit plate is equipped with a rubber pad.

[0016] The limiting pressure plate contacts the automotive parts through a rubber pad, which not only enhances friction to prevent slippage but also avoids damage to the workpiece surface caused by hard contact.

[0017] Preferably, the second electric push rod is electrically connected to the controller, and the controller can control the second electric push rod to move the limiting pressure plate, and the second electric push rod can push the limiting pressure plate to clamp and fix the automotive parts.

[0018] The controller centrally controls the second electric push rod, enabling automated clamping of automotive parts.

[0019] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0020] 1. By integrating an infrared rangefinder, a No. 1 electric push rod, and a pressure sensor, the height of automotive parts is automatically measured. The real-time feedback mechanism of the pressure sensor ensures that the detection plate stops contacting the automotive parts instantly, and at the same time drives the infrared rangefinder to accurately calculate the height of the automotive parts, reducing errors caused by human factors and improving the accuracy of the measurement results.

[0021] 2. The controller 2 controls two electric push rods to drive two limit plates to clamp and fix the automotive parts, ensuring the stability of the automotive parts during the testing process, avoiding measurement errors caused by the movement or tilting of the automotive parts, and improving the reliability of the testing.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-5 The illustrated automotive parts dimensional inspection fixture includes a workbench 1, a controller 2 mounted on the front of the workbench 1, a fixed bracket 3 mounted on the top of the workbench 1, a placement area 4 located at the center of the top of the workbench 1, a detection component 5 located directly below the fixed bracket 3 and above the placement area 4, the detection component 5 including a detection pressure plate 6, a loading rack 7 mounted on one side of the top of the detection pressure plate 6, an infrared rangefinder 8 mounted at one end of the loading rack 7 with the detection end of the infrared rangefinder 8 facing downwards, a first electric push rod 9 mounted at the center of the top of the fixed bracket 3, the working end of the first electric push rod 9 extending below the fixed bracket 3 and fixedly connected to the top of the detection pressure plate 6, and a pressure sensor 10 embedded in the center of the bottom of the detection pressure plate 6. The infrared rangefinder 8, the first electric push rod 9, and the pressure sensor 10 are all electrically connected to the controller 2.

[0031] In one aspect of this embodiment, the detection end of the infrared rangefinder 8 and the detection end of the pressure sensor 10 are both at the same height as the bottom of the detection plate 6. The detection end of the infrared rangefinder 8 can emit infrared rays towards the top of the workbench 1 and receive the reflected signals. Then, the infrared rangefinder 8 will calculate the height of the automotive parts based on the time difference of the signals and display the measurement results on the controller 2. The controller 2 can control the first electric push rod 9 to drive the detection plate 6 to perform lifting and lowering operations. The first electric push rod 9 can drive the detection plate 6 to press the top of the automotive parts. When the pressure sensor 10 detects pressure, it will send a signal to the controller 2. Subsequently, the controller 2 will immediately stop the action of the electric push rod and simultaneously start the infrared rangefinder 8 to measure the height of the automotive parts and fix the bracket. A light shield 11 is installed on the back and left and right sides of the fixed bracket 3. The light shield 11 is used to block excessive light and avoid strong light environment from interfering with the infrared rangefinder 8. An operation door 12 is installed on the front of the fixed bracket 3. A transparent observation window 13 is installed in the middle of the operation door 12. Two clamping components 14 are set on the top of the workbench 1. The two clamping components 14 are located on both sides of the placement area 4. The detection component 5 includes a second electric push rod 15. A limit pressure plate 16 is installed on the working end of the second electric push rod 15. A rubber pad 17 is installed on the clamping surface of the limit pressure plate 16. The second electric push rod 15 is electrically connected to the controller 2. The controller 2 can control the second electric push rod 15 to drive the limit pressure plate 16 to move. The second electric push rod 15 can push the limit pressure plate 16 to clamp and fix the automotive parts.

[0032] The controller 2, infrared rangefinder 8, electric actuator 9, pressure sensor 10, and electric actuator 15 mentioned above are all existing technology products, and their specific structures and functions will not be described in detail here.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-5 When using this utility model, first, open the operating door 12, place the automotive parts to be tested in the center of the placement area 4 at the top of the workbench 1, then control the two second electric push rods 15 through the controller 2 to drive the two limit pressure plates 16 to clamp and fix the automotive parts, and then close the operating door 12.

[0035] Next, the detection program is started by controller 2. Controller 2 controls the first electric push rod 9 to drive the detection pressure plate 6 down, so that the detection pressure plate 6 gradually approaches the top of the part. When the pressure sensor 10 at the bottom of the detection pressure plate 6 contacts the top of the part and generates a small pressure, the pressure sensor 10 detects the pressure and immediately sends a signal to controller 2. After receiving the signal, controller 2 will immediately stop the movement of the first electric push rod 9 to prevent excessive pressure on the workpiece. At the same time, after receiving the signal, controller 2 will immediately start the infrared rangefinder 8. The infrared rangefinder 8 emits infrared rays towards the top of the worktable 1 and receives the reflected signal. The height of the part is calculated based on the signal time difference and the measurement result is displayed on the display screen of controller 2.
