[0036] The gantry 200 is arranged on the machine table 100, and in a specific arrangement, the gantry 200 comprises a cross beam 210 and two upright columns 220, the two upright columns 220 are arranged at two ends of the cross beam 210, and one end of each upright column 220 away from the cross beam 210 is arranged on the machine table 100;

[0037] The first positioning plate 310 is mounted on the machine table 100, and a positioning recess 311 is formed on a surface of the first positioning plate 310 away from the machine table 100, the positioning recess 311 is used to accommodate the first curved surface body and the second curved surface body arranged in sequence, in a specific arrangement, the contour shape of the positioning recess 311 is matched with the contour shape of the first curved surface body, the center of the positioning recess 311 is consistent with the center of the first positioning plate 310, the positioning recess 311 is usually circular, the convex surface of the first curved surface body is away from the bottom wall of the positioning recess 311, the convex surface of the second curved surface body abuts against the convex surface of the first curved surface body, and the size of the second curved surface body is the same as that of the first curved surface body;

[0038] The first positioning frame 320 comprises a connecting assembly 321 and positioning columns 322. One end of the connecting assembly 321 is movably installed on the gantry 200, and the other end of the connecting assembly 321 extends towards the machine table 100 and is connected with at least three positioning columns 322. The three positioning columns 322 not located on the same straight line are located on the same horizontal plane and the centers of the first circles determined by the first ends of the three positioning columns 322 are located on the same vertical line with the center of the positioning groove 311. The three positioning columns 322 are used to press down the second curved surface body to make the second curved surface body abut against the first curved surface body. According to the three-point positioning plane principle, the three positioning columns 322 are used to position the horizontal plane of the second curved surface body. When the centers of the first circles determined by the first ends of the three positioning columns 322 are located on the same vertical line with the center of the positioning groove 311, the positioning columns 322 correct the position of the second curved surface body relative to the first curved surface body during the downward movement, so that the second curved surface body abuts against the first curved surface body.

[0039] In the specific operation, the first curved surface body is first placed in the positioning groove 311, and then the second curved surface body is placed above the first curved surface body. The connecting assembly 321 is moved downward to drive the positioning columns 322 to press down the second curved surface body.

The centers of the first circles determined by the first ends of the three positioning columns 322 are located on the same vertical line with the center of the positioning groove 311, so that the positioning columns 322 correct the position of the second curved surface body relative to the first curved surface body during the downward movement, so that the second curved surface body abuts against the first curved surface body. The abutting of the curved surface products is realized conveniently and quickly.

[0041] In combination with Figure 3 as shown, Figure 3The structure of the first positioning frame 320 in the embodiment of the present application is shown. In some embodiments, in order to more conveniently connect the positioning columns 322, a preferred embodiment of the connecting assembly 321 includes a connecting rod 3211 and a positioning rod 3212. One end of the connecting rod 3211 is movably connected to the gantry 200, the other end of the connecting rod 3211 extends towards the machine table 100 and is connected with the positioning rod 3212. The number of the positioning rod 3212 is at least three. The three positioning rods 3212 are arranged at intervals. Each positioning rod 3212 is provided with one positioning column 322 on the side away from the connecting rod 3211. In a specific arrangement, the three positioning rods 3212 are of the same size. The three positioning rods 3212 can be equally spaced on the end of the connecting rod 3211 away from the gantry 200. The three positioning rods 3212 are located on the same horizontal plane. The distance from the three positioning columns 322 to the center formed by the three positioning rods 3212 is the same, that is, the center of the first circle determined by the first ends of the three positioning columns 322 away from the positioning rod 3212 is also the center formed by the three positioning rods 3212.

[0042] In order to make the fitting of the second curved body and the first curved body more accurate, specifically, the number of the positioning rods 3212 is four. The four positioning rods 3212 are in the shape of a cross. The center formed by the four positioning rods 3212 is the first positioning center. The distance from the four positioning columns 322 to the first positioning center is the same. Through the above arrangement, the center of the first circle determined by the first ends of the four positioning columns 322 away from the positioning rod 3212 is also the first positioning center.

[0043] In order to more conveniently take out the first curved body and the second curved body after fitting, specifically, a plurality of first through holes 312 are provided on the first positioning plate 310 and penetrate the thickness of the first positioning plate 310. The plurality of first through holes 312 are arranged at intervals along the outer contour of the positioning groove 311 and are connected to the positioning groove 311. Through the above arrangement, it is convenient for workers to insert their fingers into the first through holes 312 to hold the first curved body and the second curved body in the positioning groove 311. It is also convenient to avoid the second curved body during the process of correcting the second curved body. In a specific arrangement, the plurality of first through holes 312 are equally spaced along the outer contour of the positioning groove 311. The positioning groove 311 is circular. The plurality of first through holes 312 are also equally spaced along the center of the positioning groove 311.

[0044] In order to facilitate the inspection of the positioning accuracy of the positioning mechanism 300 after a long time of use, the number of the plurality of first through holes 312 is consistent with the number of the positioning rods 3212, and the first through holes 312 and the positioning rods 3212 are in one-to-one correspondence. When the number of the positioning rods 3212 is four, four positioning rods 3212 in the shape of a cross have a first positioning through hole penetrating through the thickness thereof in the center, and the bottom wall of the positioning groove 311 has a second positioning through hole penetrating through the thickness of the first positioning plate 310 in the center. When the axis of the first positioning through hole coincides with the axis of the second positioning through hole, the positioning accuracy of the positioning mechanism 300 is high.

[0045] In order to more conveniently correct the position of the second curved surface body, in a preferred embodiment, the first end is in the shape of a bullet head. It is not difficult to understand that the bullet-shaped first end has a higher pressure and can correct the position of the second curved surface body faster. In order to more conveniently realize the up-down movement of the connecting assembly 321 relative to the gantry 200, in the specific arrangement, the cross beam 210 of the gantry 200 is connected with a downwardly extending first sliding rail 230, and the first positioning frame 320 further includes a connecting plate 323, one side of the connecting plate 323 being connected with one end of the connecting rod 3211, and the other side of the connecting plate 323 being provided with a first sliding block matched with the first sliding rail 230.

The first driving mechanism is arranged on the gantry 200, and the first driving mechanism is in communication connection with the control module.

In the downward movement process, the positioning column 322 connected with the first sliding block presses downward on the second curved surface body, so that the second curved surface body is fitted in the opposite direction with the first curved surface body. In the upward movement process, it is convenient for workers to take out the fitted first curved surface body and the second curved surface body and put in the next first curved surface body and the second curved surface body.
