[0040] In combination Figures 1 to 4 As shown, the rapid positioning mechanism provided by the embodiment can realize the rapid positioning of the base 200 and the tray 100, and meet the positioning requirements of the parts in horizontal machining or machining in any direction. Specifically, the rapid positioning mechanism includes the tray 100, the base 200, the positioning assembly 300, and the auxiliary assembly 400: the positioning assembly 300 includes a plurality of positioning seats 310 and a plurality of positioning pins 320, the plurality of positioning seats 310 are arranged at intervals on the base 200, the plurality of positioning pins 320 are arranged one by one on the tray 100 corresponding to the plurality of positioning seats 310, and the positioning pin 320 is inserted into the corresponding positioning seat 310 to realize the positioning of the tray 100 and the base 200; the auxiliary assembly 400 includes a first auxiliary plate 410 and a second auxiliary plate 420, the first end of the first auxiliary plate 410 is rotatably connected to the first end of the second auxiliary plate 420, the base 200 is arranged on the upper end face of the first auxiliary plate 410, and the included angle between the first auxiliary plate 410 and the second auxiliary plate 420 is adjustable to change the included angle between the base 200 and the horizontal plane.

[0041] Because a plurality of positioning seats 310 are arranged at intervals on the base 200, and a plurality of positioning pins 320 are arranged on the tray 100 corresponding to the plurality of positioning seats 310, during the machining of the parts, the rapid positioning between the base 200 and the tray 100 can be realized by inserting the positioning pin 320 into the corresponding positioning seat 310; and the repeated positioning between the base 200 and the tray 100 can be realized by the cooperation of the positioning pin 320 and the corresponding positioning seat 310.

[0042] Since the first end of the first auxiliary plate 410 is rotationally connected to the first end of the second auxiliary plate 420, and the base 200 is arranged on the upper end surface of the first auxiliary plate, during the machining process, when the machined parts need to be machined horizontally, the included angle between the first auxiliary plate 410 and the second auxiliary plate 420 is adjusted so that the first auxiliary plate 410 is perpendicular to the second auxiliary plate 420; similarly, when the machined parts need to be machined in any direction, the included angle between the first auxiliary plate 410 and the second auxiliary plate 420 is changed according to the actual needs to change the orientation of the base 200, thereby meeting the positioning needs of the machined parts during horizontal machining or machining in any direction.

[0043] In addition, the number of positioning seats 310 arranged on the base 200 is not specifically limited, and when a plurality of positioning seats 310 are arranged on the base 200, the plurality of positioning seats 310 are arranged in an array for easy positioning.

[0045] In this way, the base 200 can be arranged in any direction, and the machining of the machined parts can be carried out in any direction, thereby improving the machining efficiency. Figure 1 For example, by arranging the third auxiliary plate 430, on the one hand, when the machined parts need to be machined in any direction, if the upper end surface of the base 200 needs to be arranged in a right-up inclined manner, it is not necessary to adjust the included angle between the first auxiliary plate 410 and the second auxiliary plate 420 and then turn the direction of the entire auxiliary assembly 400, but only need to adjust the included angle between the third auxiliary plate 430 and the second auxiliary plate 420, and keep the first auxiliary plate 410 stationary, which ensures the use effect while reducing the operation difficulty; on the other hand, when the height of the machined parts is high, it is not necessary to raise the entire auxiliary assembly 400, but only need to adjust the included angle between the first auxiliary plate 410 and the second auxiliary plate 420 and the included angle between the third auxiliary plate 430 and the second auxiliary plate 420.

[0050] In combination Figure 2 As shown in the drawings, in the embodiment, the extension direction of the auxiliary seat 210 is perpendicular to the extension direction of the base 200, so that when the base 200 is arranged on the upper end surface of the first auxiliary plate 410 through the auxiliary seat 210, horizontal machining of the parts can be completed when the first driving member 440 and the second driving member 450 are both in a non-working state. Moreover, when the base 200 is arranged on the upper end surface of the first auxiliary plate 410 through the auxiliary seat 210, a plurality of positioning seats 310 can be arranged on the two surfaces of the base 200 according to requirements, and the number of the trays 100 is correspondingly set to two. In some other embodiments, the angle between the extension direction of the auxiliary seat 210 and the extension direction of the base 200 can be set to 45°, 60°, 80°, etc. according to actual requirements, which is not specifically limited here.

[0051] In order to further improve the connection strength and stability of the base 200 arranged on the first auxiliary plate 410, a storage groove is arranged on the first auxiliary plate 410, and the base 200 is fixedly arranged in the storage groove.

[0052] In order to improve the connection strength and stability of the positioning seat 310 connected to the base 200, so as to improve the positioning effect between the base 200 and the tray 100, in the embodiment, the positioning assembly 300 further comprises a plurality of positioning bolts 330, the positioning seat 310 is arranged on the base 200 through the positioning bolts 330, and the positioning pin 320 is fixedly arranged on the tray 100 through interference fit corresponding to the corresponding positioning seat 310. In order to further improve the connection strength and stability of the positioning seat 310, the same positioning seat 310 is fixedly arranged on the base 200 through a plurality of positioning bolts 330. In some other embodiments, the connection mode of the positioning seat 310 connected to the base 200 and the positioning pin 320 connected to the tray 100 can be set to welding, key connection, etc. according to actual requirements, which is not specifically limited here.

[0053] Preferably, in the positioning process, in order to ensure that the positioning pin 320 can be quickly and accurately inserted into the corresponding positioning seat 310, in the embodiment, a guide surface corresponding to the guiding of the corresponding positioning pin 320 is arranged on the positioning seat 310, and the end of the positioning pin 320 away from the tray 100 is tapered.

In the embodiment, the positioning column 340 is arranged on the base 200.

[0055] In the embodiment, the positioning column 340 is arranged on the base 200, and the positioning sleeve 350 is arranged on the tray 100, wherein a channel is formed on the tray 100 corresponding to the positioning column 340, and the channel is used as the positioning sleeve 350, so that the tray 100 and the base 200 are tightly attached after positioning, thereby further improving the positioning effect. When machining parts, especially large parts, the positioning pin 320 can be inserted into the corresponding positioning seat 310 during positioning. If the diameter of the positioning pin 320 is small, it is impossible to achieve accurate positioning of the tray 100 and the base 200. In this state, the positioning pin 320 is inserted into the corresponding positioning seat 310 after the positioning column 340 is inserted into the positioning sleeve 350 to complete the rough positioning of the tray 100 and the base 200, so as to achieve accurate positioning. By arranging the positioning column 340 and the positioning sleeve 350, the situation that the positioning accuracy is poor due to the small diameter of the positioning pin 320 is avoided.

[0056] In order to further improve the positioning effect between the base 200 and the tray 100, a plurality of positioning columns 340 are arranged on the base 200 in a staggered manner, and the positioning sleeves 350 are arranged correspondingly. In the embodiment, two positioning columns 340 are arranged on the base 200, and the two positioning columns 340 are arranged at opposite corners of the base 200, and the two positioning sleeves 350 are arranged correspondingly.
