Description

Technical Field

[0001] This utility model relates to the field of measurement technology in the processing and manufacturing of corrugated pipes, and particularly to the detection of the width and height of the weld bead after welding the inner diameter of the corrugated pipe. Background Technology

[0002] Welded bellows are a new type of component that has emerged in recent years both domestically and internationally. They are generally used as core components in domestic semiconductor equipment such as PVD, CVD, PECVD, MOCVD, etching machines, and ion implanters. Simultaneously, the product is widely used in a range of high-end industries including accelerators, solar photovoltaics, pharmaceutical equipment, and vacuum equipment.

[0003] Welded corrugated pipes have both inner diameter welding and outer diameter welding processes. Traditionally, after inner diameter welding, the width and thickness of the weld bead in the corrugated pipe need to be measured manually. However, the traditional measurement of the inner diameter of corrugated pipes relies on manual measurement using tools such as calipers, which cannot achieve full-position measurement and is inefficient. Therefore, we propose a 3D contour inspection machine for welded corrugated pipes. Utility Model Content

[0008] The base and side support frame are fixedly installed on top of the base. A connecting bracket is set at the upper end of the side support frame. The connecting bracket is a C-shaped structural block. A detection unit is set below the connecting bracket. The detection unit includes a measuring head and a calculation unit. The measuring head emits a measuring beam downward through a camera to photograph the inner edge of the part and then transmits the data to the calculation unit to obtain the data of the inner contour of the part.

[0009] Preferably, a support frame is provided in the middle of the base, a rotating base is provided at the upper end of the support frame, a rotating seat is rotatably installed on the top of the rotating base, an mounting seat is fixedly installed on the outer side of the upper end of the rotating seat by bolts, and a corrugated tube to be tested is installed on the inner side of the mounting seat. The measuring beam emits light and inserts it into the inner diameter of the corrugated tube for measurement.

[0010] Preferably, a drive motor is provided below the rotating base, which drives the mounting base and the rotating base above to rotate together, thereby driving the bellows part to be measured to rotate together, realizing automated rotational inner diameter measurement, which is efficient and stable and can replace manual operation.

[0011] Preferably, the device includes overall adjustment and local adjustment.

[0012] Overall adjustment refers to adjusting the overall position of the detection unit or mounting base.

[0013] The mounting position can be adjusted by selecting from several sets of threaded holes on the base surface, according to the usage requirements. The mounting position is adjusted by selecting the position of the support frame in the mounting threaded holes of the base.

[0014] Preferably, the adjustment of the position of the detection unit includes a first adjustment block and a second adjustment block. The first adjustment block can adjust the position of the support frame on the opposite side of the base.

[0015] Preferably, the surface of the second adjusting block is provided with several sets of threaded holes. By selecting the position of the connecting bracket in the hole diameter of the second adjusting block, the position of the support frame on the opposite side of the connecting bracket can be adjusted.

[0016] (III) Beneficial Effects

[0017] The corresponding detection unit and mounting position are selected according to the component to be tested. The component to be tested is then placed in the mounting base. The inner edge of the component is photographed by the measuring beam emitted by the detection unit, and the data is transmitted to the calculation unit. Then, the drive motor located below the rotating base drives the mounting base and the rotating base to rotate together, thereby causing the bellows component to be tested to rotate together, realizing automated rotation inner diameter measurement.

The upper end of the side support frame 2 is provided with a connecting bracket 3, which is a C-shaped structural block. The lower part of the connecting bracket 3 is provided with a detection unit 4, which includes a measuring head and a calculation unit. The measuring head emits a measuring beam 8 downward through a camera to photograph the inner edge of the part and then transmits the data to the calculation unit to obtain the data of the inner contour of the part.

[0027] A support frame 5 is provided in the middle of the base 1. A rotating base 6 is provided at the upper end of the support frame 5. A rotating seat 11 is rotatably installed on the top of the rotating base 6. An mounting seat 7 is fixedly installed on the outer side of the upper end of the rotating seat 11 by bolts. A corrugated tube to be tested is installed on the inner side of the mounting seat 7. The measuring beam 8 emits light and inserts it into the inner diameter of the corrugated tube for measurement.

[0028] The rotating base 6 is equipped with a drive motor, which drives the mounting base 7 and the rotating base 11 above to rotate together, thereby causing the bellows part to be measured to rotate together, realizing automated rotational inner diameter measurement, which is efficient and stable and can replace manual operation.

[0029] In addition, our testing organization has implemented multiple flexible designs to better match the dimensional processing requirements of different components, including overall adjustment and local adjustment.

[0030] Overall adjustment refers to adjusting the overall position of the detection unit 4 or the mounting base 7.

[0031] The position of the mounting base 7 is adjusted as follows: The surface of the base 1 has several sets of threaded holes, which can be selected according to usage requirements. The position of the mounting base 7 is adjusted by the support frame 5 at the location of the threaded holes in the base 1.

[0032] The adjustment of the position of the detection unit 4 includes a first adjusting block 9 and a second adjusting block 10. The first adjusting block 9 can adjust the position of the support frame 2 on the opposite side of the base 1. The surface of the second adjusting block 10 is provided with several sets of threaded holes. By selecting the position of the connecting bracket 3 in the hole diameter of the second adjusting block 10, the second adjusting block 10 can adjust the position of the connecting bracket 3 on the opposite side of the support frame 2.

[0033] Local adjustment is a matching design for the shape of mounting base 7. It is designed to match the size of the components and is assembled with bolts, making it easy to disassemble and install.

[0034] Beneficial effects: Select the corresponding detection unit 4 and mounting base 7 according to the part to be tested, then place the part to be tested in the mounting base 7, and then take a picture of the inner edge of the part by the measuring beam 8 emitted by the detection unit 4 and transmit the data to the calculation unit. Then, the drive motor set under the rotating base 6 drives the mounting base 7 and the rotating base 11 to rotate together, thereby driving the bellows part to be tested to rotate together, realizing automated rotation inner diameter measurement.
