Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an automatic calibration device for testing the roughness of automotive parts. Background Technology

[0002] Surface roughness of automotive parts is a key indicator of their quality, directly affecting their wear resistance, sealing performance, assembly accuracy, and service life. Currently, portable automotive parts roughness testers are widely used due to their flexibility and ease of on-site testing. However, to ensure testing accuracy, portable roughness testers require periodic calibration using a calibration plate (providing a standard roughness reference surface) and a calibration block (simulating the roughness characteristics of the actual workpiece being tested).

[0003] Current calibration work largely relies on manual labor: operators must manually place the roughness tester on the calibration plate, adjust its position to ensure precise contact between the sensor probe and the calibration block, and then manually compare and correct the calibration parameters. The accuracy of manual operation is greatly affected by human factors, such as uneven contact force between the probe and the calibration block, or misalignment of the placement position, which can easily lead to calibration errors and affect the reliability of subsequent test data. In addition, long-term manual operation can easily lead to fatigue and omission of calibration steps (such as failure to complete multi-level calibration according to the standard procedure), further affecting the calibration effect. In order to solve the above problems, this utility model proposes an automatic calibration device for roughness testing of automotive parts. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, the automatic calibration device for roughness testing of automotive parts includes a calibration base plate 1, a roughness meter 2, and a calibration block 10. The roughness meter 2 and the calibration block 10 are existing components. The upper end of the calibration base plate 1 is provided with a sliding groove 12, and a moving frame 6 is provided in the sliding groove 12. The calibration base plate 1 is provided with a first driving mechanism for driving the roughness meter 2 to move. The first driving mechanism includes a fixed block fixedly connected to the upper end of the calibration base plate 1. The side wall of the fixed block is provided with a first electric push rod 7. The output end of the first electric push rod 7 is rotatably connected to the side wall of the moving frame 6. The bottom of the moving frame 6 is rotatably connected with a rotating shaft 5. The upper end of the rotating shaft 5 is fixedly connected with a placement frame 4. Both sides of the roughness meter 2 are fixedly connected with limiting frames 3 that can cooperate with the placement frame 4. The upper end of the calibration base plate 1 is fixedly connected with a limiting frame 9 and a controller 8. The limiting frame 9 is used to place the calibration block 10 (the calibration block 10 is placed in the groove of the limiting frame 9). The controller 8 is mounted on the calibration base plate 1 through a mounting rod.

[0024] The side wall of the movable frame 6 is provided with a second driving mechanism for driving the roughness meter 2 to move and rotate. The second driving mechanism includes a mounting bracket 20 fixedly connected to the side wall of the movable frame 6, a second electric push rod 18 fixedly connected to the side wall of the mounting bracket 20, a rack 19 fixedly connected to the output end of the second electric push rod 18, and a gear fixedly connected to the side wall of the rotating shaft 5.

[0025] In this utility model, a movable groove 13 is provided at the lower end of the calibration base plate 1, and a movable plate 14 is slidably connected in the movable groove 13. A calibration indicator plate 15 is provided at the bottom of the movable plate 14. The calibration indicator plate 15 has calibration-related steps and illustrations written on it, which can intuitively guide the operator to complete the preparatory work such as setting panel parameters before calibration. It is especially user-friendly for novice operators, effectively avoiding omissions of steps due to unfamiliarity with operation and improving the standardization of calibration.

[0026] In this utility model, the calibration base plate 1 has a magnet 17 on its side wall. The movable plate 14 includes a vertical plate that slides in the movable groove 13 and a horizontal plate. The vertical plate has a T-shaped cross section and is made of iron sheet. The cooperation between the magnet 17 and the iron sheet vertical plate can achieve a stable fixation after the movable plate 14 is stored, preventing the movable plate 14 from accidentally sliding out when the equipment is moved or vibrated. The T-shaped vertical plate design can prevent the movable plate 14 from falling out of the movable groove 13, improving structural safety. The lower end of the movable plate 14 has an opening to facilitate pulling the movable plate 14.

[0027] In this utility model, the lower end of the calibration base plate 1 is provided with multiple anti-slip pads 16. The multiple anti-slip pads 16 can increase the friction between the calibration base plate 1 and the placement surface, prevent the equipment from sliding due to vibration during calibration or testing, and ensure overall stability. The moving frame 6 is slidably connected to the sliding groove 12. The bottom of the moving frame 6 is located in the sliding groove 12, so that the moving frame 6 can only move left and right, avoiding the moving frame 6 from moving back and forth at will.

[0028] In this utility model, the side wall of the limiting frame 3 is provided with multiple grooves, which are equally spaced to increase the friction between the hand and the limiting frame 3, making it easier for the operator to quickly pick up and put down the roughness tester 2. Especially after the roughness tester 2 is calibrated, it is easier to adjust its position or perform subsequent operations, thus improving the human-computer interaction experience.

[0029] In the initial state, the roughness meter 2 is separated from the placement frame 4, and the output end of the first electric push rod 7 extends.

[0030] When in use, the operator only needs to place the roughness tester 2 in the placement frame 4, so that the limit frames 3 on both sides fit on both sides of the placement frame 4 to complete the initial positioning of the roughness tester 2. The device is started by the controller 8, the first drive mechanism works, the first electric push rod 7 retracts, and drives the moving frame 6 to move along the sliding groove 12 towards the limit frame 9 until the sensor probe of the roughness tester 2 accurately contacts the calibration block 10 on the limit frame 9 to complete the automatic alignment. Then the roughness tester 2 is started to perform detection and complete the calibration, which replaces manual placement and reduces position deviation.

[0031] During calibration, the controller 8 can automatically compare and correct calibration parameters according to the preset program. After calibration, the first electric push rod 7 extends, driving the moving frame 6 and the roughness tester 2 to reset. If component inspection is required, the second drive mechanism is activated: the second electric push rod 18 extends and retracts, driving the rack 19 to move. The rack 19 meshes with the gear on the side wall of the rotating shaft 5, driving the rotating shaft 5 to rotate, thereby driving the placement frame 4 and the roughness tester 2 to change direction (such as turning towards the operator's side). At this time, the operator can directly place the component to be inspected under the roughness tester 2 without removing the roughness tester 2 to perform the inspection, simplifying the operation process.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
