The two clamping mechanisms 3 are respectively arranged at two sides of the positioning mechanism 2, and each clamping mechanism 3 is provided with at least one clamping block 31, at least one clamping block 31 is arranged opposite to one of the positioning blocks 21, that is, each positioning block 21 corresponds to one clamping block 31 of each clamping mechanism 3. The driving mechanism 4 is connected to the two clamping mechanisms 3, respectively, and the driving mechanism 4 drives the two clamping mechanisms 3 to move linearly, for example, the two clamping mechanisms 3 move towards each other or back, so that each clamping block 31 abuts against one positioning block 21, and at least one accessory is pressed between one clamping block 31 and one positioning block 21. In the present invention, the driving mechanism 4 may be a cylinder or an electric push rod.

Preferably, please refer to fig. 3, which is a partially enlarged view of a portion a in fig. 1. Each positioning block 21 is provided with a positioning slot 211. The positioning groove 211 is, for example, a semicircular groove, a square groove, or a polygonal groove. For example, the shape of the positioning slot 211 matches the shape of the accessory to be positioned. For example, the number of the positioning grooves 211 is at least two, and at least one positioning groove 211 is arranged on one end face of the positioning block 21 corresponding to one clamping block 31, so that at least two accessories can be clamped by matching one positioning block 21 with one clamping block 31.

For example, the maximum distance from the inner wall of the blanking partition 22 to the side of the positioning block 21 is smaller than the maximum distance from the edge of the blanking channel 11 to the side of the positioning block 21. At least one clamping block 31 penetrates through one blanking partition plate 22 and then abuts against one positioning block 21. Guarantee through blanking baffle 22 that the accessory can accurately fall into blanking passageway 11 when dropping by constant head tank 211, improve positioner job stabilization nature.

Preferably, as shown in fig. 1 and 2, the positioning mechanism 2 further includes at least one detecting component 23. Each detecting member 23 corresponds to one positioning groove 211.

By combining the signal with a conventional automatic control system, whether the accessory is in place on the positioning groove 211 can be judged, and the positioning precision of the positioning device is further improved.

Preferably, as shown with continued reference to fig. 1-3, each clamping mechanism 3 further includes a connecting plate 32. The number and the positions of the clamping blocks 31 on each clamping mechanism 3 correspond to those of the positioning blocks 21 of the positioning mechanism 2.

Preferably, as shown in fig. 1 and fig. 2, the positioning device further includes at least one limiting mechanism 5. The at least one limiting means 5 is used to prevent excessive displacement of the clamping means 3 when clamping the fitting, and thus to prevent damage to the positioning means 2 and the clamping means 3. Wherein, the limiting mechanism 5 is arranged between the two clamping mechanisms 3 and is positioned on the moving path of at least one sliding base 34. When the clamping mechanism 3 clamps the accessory, the at least one limiting mechanism 5 abuts against the at least one sliding base 34, so that the clamping mechanism 3 is limited. Wherein clamping mechanism 3 is the same with clamping mechanism 3 is the distance of locating piece 211 to the distance of stop gear 5, so, when guaranteeing that clamping mechanism 3 presss from both sides tight accessory, stop gear 5 is just spacing to clamping mechanism 3, improves spacing effect. Preferably, each limiting mechanism 5 includes two limiting frames 51 and two limiting members 52. The two limiting frames 51 are disposed on a moving path of one sliding base 34, and each limiting member 52 is disposed on one limiting frame 51 and corresponds to one sliding base 34 of the clamping mechanism 3. The stopper 52 abuts against the slide base 34 to limit the clamping mechanism 3 when it is clamped. The position-limiting member 52 can be a buffer screw or a buffer rod, and of course, the position-limiting member 52 can also be other elastic position-limiting members.

Each buffer mechanism 6 is located at the end of the path of movement of a clamping mechanism 3, e.g. each buffer mechanism 6 is located on the side of a clamping mechanism 3 remote from the positioning mechanism 2. The buffer mechanism 6 is used for buffering when the two clamping mechanisms 3 move back to the maximum position. Specifically, when the two clamping mechanisms 3 move away from each other to the maximum position, one end of each buffer mechanism 6 abuts against one clamping mechanism 3, so that the clamping mechanisms 3 are buffered. Preferably, each buffer mechanism 6 includes a buffer frame 61 and a buffer rod 62. The buffer frame 61 is disposed on the mounting plate 1 and located on a side of the clamping mechanism 3 away from the positioning mechanism 2. The buffer rod 62 is disposed on the buffer frame 61.
