DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-3 As shown, an auxiliary tooling for measuring arc-shaped casing disclosed in the technical solution includes a slide rail platform 1, the slide rail platform 1 includes a slide rail limit platform 11 and a limit plate 12, the slide rail platform 1 is composed of two rectangular square tubes and a connecting rod, the limit plate 12 is fixedly connected to the side of one side of the slide rail limit platform 11, and the two rectangular square tubes, the connecting rod and the limit plate 12 form a rectangular frame. Slide rails 13 are provided on the sides (i.e., two rectangular square tubes) adjacent to the slide rail limit platform 11 and the limit plate 12.

[0026] A fixing device 2 is also provided, which spans the slide rail limiting platform 11 and is installed on the slide rail 13, on which the angle measuring device 3 and the distance measuring device 4 are also installed. In order to avoid movement interference, two slide rails 13 are provided here, the fixing device 2 is installed on the upper slide rail, and the angle measuring device 3 and the distance measuring device 4 are installed on the lower slide rail. The slide rail 13, the fixing device 2, and the limiting plate 12 are used to achieve multi-angle and multi-size position adjustment, fix arc tubes of different specifications, facilitate subsequent size measurement and overall connection, and save working time.

[0027] The fixing device 2 includes two vertical poles 21 and a fixed frame 22, which are combined into a structure similar to an arch. The fixed frame 22 is rotatably connected to the vertical poles 21. The fixed frame 22 includes two sliding frames 221. The two sliding frames 221 are rotatably connected to the two vertical poles 21 respectively. Two fixing rods 222 are inserted between the two sliding frames 221. The fixing rods 222 here are provided with threads at both ends, and screw rods can be directly used. Nuts are threadedly connected at both ends of the fixing rods 222. The distance between the two nuts is adjusted by the tightness of the nuts. At the same time, the fixing is achieved by the extrusion force of the nuts. Changing the distance between the two fixing rods 222 can achieve the fixation of arc tubes of different sizes, thereby improving the applicability of the device.

[0028] The lower side of the vertical rod 21 is slidably connected to the slide rail 13 through a sliding rod 23. The sliding rod 23 is provided with a nut threadedly connected to the side away from the slide rail 13. The sliding rod 23 here also adopts a screw structure, which is convenient for fixing the position through the nut.

[0029] The vertical rod 21 is provided with a slide groove along its axial direction, and the sliding frame 221 can slide vertically. The slide groove provided here is used for adjusting the size in the vertical direction, which improves the applicability of the device. A fixed structure is provided on the outside of the sliding frame 221, and the fixed structure here is also a screw rod, and both ends are threadedly connected to nuts.

[0030] The angle measuring device 3 includes a first connecting rod 31 and a laser angle measuring instrument 32 slidably connected to the first connecting rod 31, and nuts are threadedly connected to both ends of the first connecting rod 31. The distance measuring device 4 includes a second connecting rod 41 and a laser distance measuring instrument 42 slidably connected to the second connecting rod 41, and nuts are threadedly connected to both ends of the second connecting rod 41. The laser angle measuring instrument 32 and the laser distance measuring instrument 42 are used to measure the data of the arc tube, and the two data are combined to complete the rapid verification of the size of the arc tube.

[0031] The method for using the auxiliary tooling includes the following steps:

[0032] a. Assemble the tooling, estimate the size of the arc tube, install the fixture 2, the angle measuring device 3 and the distance measuring device 4 in the appropriate position and pre-fix them;

[0033] b. Place one end of one or more arc tubes against the limit plate 12, and fix the other end through the fixing device 2; place one end of the arc tube above the limit plate 12, adjust the fixing device 2 to the upper middle part of the arc tube, adjust the spacing and angle of the two fixing rods 222 until the screw rod is in firm contact with the sleeve, adjust the nut to tighten, and complete the fixation of the arc sleeve;

[0034] c. By moving the angle measuring device 3 and the distance measuring device 4 on the slide rail 13, the data of the positions of both ends of the arc tube are measured and recorded by the laser angle measuring instrument 32 and the laser distance measuring instrument 42;

[0035] Adjust the position of the laser distance measuring instrument 42 to measure the inner and outer dimensions of the casing (L1, L2, L3, L4, L1, L3 are the same measuring point, L2, L4 are the same measuring point), and the calculation formula of the casing center chord length L is: Adjust the light beam of the laser angle measuring instrument 32 to be parallel to the two end surfaces of the casing, measure the angle at this time, that is, the bending angle a of the arc casing, and quickly check the size of the arc casing based on the chord length L and the bending angle a;

[0036] d. In the above step c, if multiple arc tubes are to be measured in batches, just repeat step c. The above operation process is repeated to complete the size inspection of the arc tube. After the size review of arc tubes of the same specification is completed, they are fixed in groups for overall connection to complete the assembly of the arc sleeve.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
