Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile parts measurement technology, in particular to a snap gauge gauge for measuring the inner diameter of automobile parts. BACKGROUND

[0002] Automobile parts are units that make up the whole of automobile parts processing and products that serve automobile parts processing. In order to reduce costs and occupy the market, many automobile parts multinational companies have developed internationally. European automobile parts manufacturers have invested overseas and produced internationally. North American automobile parts manufacturers have invested in Europe and also want to expand the Eastern European market. Japanese automobile companies have established their own branch production facilities worldwide. Automobile parts need to use roughness measuring devices to measure their roughness during production.

[0003] Patent No. CN202020600185.0 discloses a finished part measuring instrument after processing, which comprises a fixing table, a fixing frame, a roughness detector and a measuring device. The first clamping plate, the second clamping plate and the limiting groove are arranged to stably fix the parts on the fixing seat and prevent displacement of the parts during clamping. The clamping pad clamps the parts to better protect the clamped parts. The first distance sensor and the second distance sensor are arranged to measure the size of parts of different sizes and shapes. The slider, the slide rail and the roughness detector are arranged to measure the roughness of the surface of the parts during size measurement.

[0004] However, the existing automobile parts measuring device only measures the overall size of the automobile parts, cannot conveniently measure the inner diameter of the automobile parts, and needs to clamp the parts, which requires an additional clamping mechanism, which is very inconvenient. Moreover, the parts cannot be effectively cleaned during clamping. SUMMARY

[0005] The present application aims to provide a snap gauge gauge for measuring the inner diameter of automobile parts, which solves the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a snap gauge gauge for measuring the inner diameter of automobile parts, comprising a device bottom box, an inner diameter measuring mechanism and an adjusting and cleaning mechanism are arranged on the front side of the device bottom box.

[0007] The inner diameter measuring mechanism comprises a first fixed plate, a second fixed plate, a motor, a rotating rod, a threaded wall, a moving plate, a bearing, a first fixed strip, an electric telescopic cylinder, a second fixed strip and an infrared distance measuring sensor; the left and right ends of the front side of the device bottom box are fixedly connected with the first fixed plate and the second fixed plate respectively, the right side of the second fixed plate is boltedly connected with the motor, the left side of the motor is boltedly connected with the second fixed plate, the motor shaft of the motor is fixedly connected with the rotating rod penetrating through the second fixed plate, the left side of the rotating rod is rotatably connected with the bearing, the left side of the bearing is fixedly connected with the first fixed plate, the left and right ends of the outer side of the rotating rod are provided with threaded walls, and the moving plate penetrates through the threaded walls on the outer side, the threaded walls are threadedly connected with the screw holes in the moving plate, the top of the moving plate is fixedly connected with the first fixed strip, the top of the first fixed strip is provided with a circular groove, the electric telescopic cylinder is fixedly connected in the circular groove, and the second fixed strip is fixedly connected to the top of the electric telescopic cylinder.

[0008] The adjusting and cleaning mechanism comprises a square hole, a sliding block, a scale bar, a first fixed shell, a second fixed shell, first cleaning bristles and second cleaning bristles; the left and right sides and the top of the second fixed strip are provided with square holes, the sliding block is slidably connected in the square hole at the top, the upper and lower ends of the left and right sides of the second fixed strip are marked with scale bars, the rear side of the first fixed strip and the bottom of the second fixed strip are boltedly connected with the first fixed shell and the second fixed shell respectively, and the rear side of the first fixed shell and the bottom of the second fixed shell are fixedly connected with the first cleaning bristles and the second cleaning bristles respectively.

[0009] As a preferred embodiment of the application, the bottom end of the inside of the device bottom box is boltedly connected with an electric machine, the top of the electric machine is rotatably connected with an electric machine shaft, and the top of the electric machine shaft is fixedly connected with a rotating disc penetrating through the device bottom box.

[0010] As a preferred embodiment of the application, the left and right sides of the top of the device bottom box are boltedly connected with fixed frame plates, and the bottom end of the middle of the fixed frame plate is boltedly connected with a panoramic camera.

[0011] As a preferred embodiment of the application, the bottom of the front side of the device bottom box is embedded with an industrial computer, and the industrial computer is signal-connected with the panoramic camera and the infrared distance measuring sensor.

[0012] As a preferred embodiment of the application, the left and right sides of the inside of the moving plate are fixedly connected with the first fixed plate and the second fixed plate respectively.

[0013] As a preferred embodiment of the application, the threaded walls at the left and right ends of the outer side of the rotating rod are oppositely threaded.

[0014] In a preferred embodiment of the present invention, the device base box, the first fixing strip, the second fixing strip, the fixing frame plate, the first fixing plate, the second fixing plate, the rotating rod, the moving plate, the first fixing shell and the second fixing shell are all made of stainless metal.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention, by setting fixed strips and infrared ranging sensors on a moving plate, allows the moving plate to move using a threaded rod. When the two second fixed strips coincide with the inner diameter sides of the component, the distance currently detected by the infrared ranging sensor is the inner diameter of the component. This inspection mechanism is convenient and simple, eliminating the need for clamping mechanisms to clamp the component. Furthermore, the second fixed strips are equipped with scale strips and sliding blocks, enabling manual detection of the overall size of the component. In cases of irregular component shapes, multi-position dimensional inspection can be performed, facilitating the more practical use of a caliper gauge for measuring the inner diameter of automotive parts.

[0017] 2. Because the present invention is provided with a fixed housing and cleaning bristles on the first and second fixed bars, the position of the second fixed bar can be adjusted by an electric telescopic cylinder, and the sides and tops of the automotive parts can be cleaned by the cleaning bristles on the first and second fixed bars. The combination of the measuring mechanism and the cleaning mechanism makes it more practical to use a caliper gauge for measuring the inner diameter of automotive parts.

[0018] 3. Because a panoramic camera is installed at the bottom of the fixed frame plate, the panoramic view shown by the camera can be displayed on the industrial control computer. This allows for a more accurate vertical view of whether the second fixing strip coincides with the inner diameter edge of the component, avoiding measurement errors caused by viewing angle issues. This makes it more practical to use a caliper gauge for measuring the inner diameter of automotive parts.

[0019] 4. Because the present invention has a motor and a rotating disk inside the device base box, the parts can be placed on the rotating disk and driven to rotate by the motor. In conjunction with the cleaning bristles on the fixing strip, the parts can be cleaned efficiently by rotation, which is conducive to the more practical use of a caliper gauge for measuring the inner diameter of automotive parts.

[0028] Please see Figures 1-4 The present invention provides a technical solution: a caliper gauge for measuring the inner diameter of automotive parts, comprising a device base box 1, wherein an inner diameter measuring mechanism and an adjustment and cleaning mechanism are provided on the front side of the device base box 1;

[0029] The inner diameter measuring mechanism includes a first fixed plate 3, a second fixed plate 2, a motor 4, a rotating rod 5, a threaded wall 6, a moving plate 8, a bearing 7, a first fixed bar 10, an electric telescopic cylinder 15, a second fixed bar 11, and an infrared ranging sensor 9. The first fixed plate 3 and the second fixed plate 2 are fixedly connected to the left and right ends of the front side of the device base box 1, respectively. The motor 4 is bolted to the right side of the second fixed plate 2, and the second fixed plate 2 is bolted to the left side of the motor 4. The motor shaft of the motor 4 passes through the second fixed plate 2 and is fixedly connected to the rotating rod 5. The bearing 7 is rotatably connected to the left side of the rotating rod 5, and the first fixed plate 3 is fixedly connected to the left side of the bearing 7. Threaded walls 6 are provided on both the left and right ends of the outer side of the rotating rod 5, and the moving plate 8 passes through the outer side of the threaded wall 6. The threaded wall 6 is threadedly connected to the threaded hole in the moving plate 8. The first fixed bar 10 is fixedly connected to the top of the moving plate 8. The first fixed bar 10 has a circular groove 14 on the top of the first fixed bar 10. The electric telescopic cylinder 15 is fixedly connected inside the circular groove 14, and the second fixed bar 11 is fixedly connected to the top of the electric telescopic cylinder 15.

[0030] The adjustable cleaning mechanism includes a square hole 16, a sliding block 18, a scale bar 17, a first fixed housing 21, a second fixed housing 19, a first cleaning bristle 22, and a second cleaning bristle 20. The second fixed strip 11 has square holes 16 on its left and right sides and top, and the sliding block 18 is slidably connected inside the square hole 16 at the top. The upper and lower ends of the left and right sides of the second fixed strip 11 are engraved with scale bars 17. The first fixed housing 21 and the second fixed housing 19 are bolted to the rear side of the first fixed strip 10 and the bottom of the second fixed strip 11, respectively. The first cleaning bristle 22 and the second cleaning bristle 20 are fixedly connected to the rear side of the first fixed housing 21 and the bottom of the second fixed housing 19, respectively.

[0031] It should be noted that, first, connect motor 4, infrared ranging sensor 9, industrial control computer 13, electric telescopic cylinder 15, motor 23, and panoramic camera 26 to an external power supply. Then, connect motor 4, infrared ranging sensor 9, industrial control computer 13, electric telescopic cylinder 15, motor 23, and panoramic camera 26 to an external control switch signal. After connection, place the car parts on the rotating disk 25, then turn on motor 4. Motor 4 drives the motor shaft, which in turn drives the rotating rod 5. The rotating rod 5 drives the two moving plates 8 to move outward or inward simultaneously. The moving plate drives the first fixed strip 10, which in turn drives the second fixed strip 11.
