As shown in fig. 1 and 2, the present embodiment provides a positioning fixture, which includes a bearing seat 1 and two positioning pushing claws 2, wherein a bearing portion 11 for bearing at least two stacked to-be-positioned pieces 10 is provided on the bearing seat 1, a positioning column 12 is provided on the bearing portion 11, and the positioning column 12 is used for simultaneously penetrating through at least two to-be-positioned pieces 10; the two positioning pushing claws 2 are movably arranged on the bearing seat 1, the two positioning pushing claws 2 are respectively arranged on two opposite sides of the bearing part 11, the two positioning pushing claws 2 can be close to or far away from each other, the absorption part 3 is arranged on one positioning pushing claw 2, and the absorption part 3 can absorb the side walls of all pieces 10 to be positioned on the bearing part 11 at the same time.

In the positioning jig provided in this embodiment, when positioning is performed, at least two pieces to be positioned 10 pass through the positioning column 12 and are stacked on the bearing part 11 of the bearing seat 1 again, the positioning column 12 performs coarse positioning on the pieces to be positioned 10, since the adsorption piece 3 is arranged in one of the positioning pushing claws 2, the adsorption piece 3 adsorbs one sides of all pieces to be positioned 10 simultaneously, one sides of all pieces to be positioned 10 are aligned, then the two positioning pushing claws 2 are mutually close to push all pieces to be positioned 10 to synchronously move until the opposite sides of the widest pieces to be positioned 10 are abutted, and since all pieces to be positioned 10 are aligned and synchronous at one side all the time in the moving process, the relative positions of all pieces to be positioned 10 are not deviated, thereby realizing accurate positioning and effectively improving the yield of products.

It can be understood that the positioning column 12 is inserted into the to-be-positioned member 10, the positioning column 12 performs coarse positioning on the to-be-positioned member 10, and under the coarse positioning action of the positioning column 12, the to-be-positioned member 10 can translate within a certain range and rotate around the positioning column 12. When the to-be-positioned member 10 is just placed on the carrying portion 11, the to-be-positioned member 10 may be shifted in position or may be skewed in angle, so that the to-be-positioned member 10 may translate and rotate under the adsorption action of the adsorbing member 3.

Specifically, the adsorbing member 3 is a magnet. After the to-be-positioned pieces 10 are placed on the bearing part 11, under the magnetic attraction of the magnet, all to-be-positioned pieces 10 move towards the positioning pushing claw 2 provided with the magnet and rotate around the positioning column 12 until abutting against the positioning pushing claw 2, the relative positions of all to-be-positioned pieces 10 are fixed, and the relative positions of all to-be-positioned pieces 10 cannot change in the pushing process of the positioning pushing claw 2, so that the relative positions of all to-be-positioned pieces 10 are fixed, and after the widest one to-be-positioned piece 10 is clamped, all to-be-positioned pieces 10 are accurately positioned.

Alternatively, the adsorbing member 3 is provided outside the sidewall of the positioning pawl 2 facing the bearing portion 11.

Specifically, in the present embodiment, the adsorbing member 3 is embedded in the positioning pawl 2. The adsorption piece 3 can realize the adsorption positioning of the piece 10 to be positioned and is firmly connected with the positioning pushing claw 2.

Alternatively, in other embodiments, the adsorbing member 3 may be a negative pressure adsorbing device, and the specific structure and working principle of the negative pressure adsorbing device may refer to the prior art, which is not described herein.

Specifically, as shown in fig. 3 and 4, the positioning pawl 2 has a pushing plane 21 thereon, and the pushing plane 21 can simultaneously push against the side walls of all the pieces to be positioned 10. When the side walls of the plurality of pieces to be positioned 10 are simultaneously abutted against the pushing plane 21, one sides of the plurality of pieces to be positioned 10 are aligned, and the relative positions of the plurality of pieces to be positioned 10 are fixed.

For convenience of description, the two members to be positioned 10 are referred to as a first member to be positioned 10a and a second member to be positioned 10b, respectively, and the length and width of the first member to be positioned 10a are smaller than the length and width of the second member to be positioned 10b, respectively, as shown in fig. 3 and 4. During positioning, the larger second to-be-positioned piece 10b is directly placed on the bearing part 11, and the smaller first to-be-positioned piece 10a is placed on the second to-be-positioned piece 10b, so that friction force of the first to-be-positioned piece 10a in the moving process can be reduced, and the two to-be-positioned pieces 10 can be adsorbed in place.

Specifically, the side wall of the positioning pawl 2 facing the carrying portion 11 is provided with a first protruding portion, and the surface of the first protruding portion facing the carrying portion 11 is a pushing plane 21. So arranged, the abutment plane 21 can be brought into close abutment against the side wall of the piece 10 to be positioned.

More specifically, a limit projection 22 is provided above the pushing plane 21, and the limit projection 22 can be abutted against the top surface of the member to be positioned 10. As shown in fig. 4, when the two positioning pawls 2 are simultaneously abutted against the second to-be-positioned member 10b, the limiting protrusions 22 are abutted against the top surface of the first to-be-positioned member 10a to limit the vertical direction of the first to-be-positioned member 10a, so as to prevent the first to-be-positioned member 10a from being separated upward.

Specifically, the bearing portion 11 includes a bearing surface 111, the positioning post 12 is disposed on the bearing surface 111, the bearing surface 111 is used for directly bearing the piece 10 to be positioned with the largest dimension along the direction in which the two positioning pawls 2 are spaced from each other, and the shape of the bottom surface of the piece 10 to be positioned is adapted to the shape of the bearing surface 111. That is, during positioning operation, the widest to-be-positioned piece 10 is directly placed on the bearing surface 111, so that the two positioning pawls 2 can be simultaneously abutted against opposite sides of the widest to-be-positioned piece 10, and the narrower to-be-positioned piece 10 is placed on the widest to-be-positioned piece 10, so that the relative positions of the two to-be-positioned pieces 10 can be conveniently adjusted. The shape of the bearing surface 111 is set to be adapted to the shape of the bottom surface of the widest piece to be positioned 10, and illustratively, if the bottom surface of the widest piece to be positioned 10 is an arc surface, the shape of the bearing surface 111 is set to be an arc surface, and if the bottom surface of the widest piece to be positioned 10 is a plane, the shape of the bearing surface 111 is set to be a plane; further, if the bottom surface of the widest part to be positioned 10 is a rectangular plane, the bearing surface 111 is set to be a rectangular plane, so that the bonding area of the two parts is larger, and the stability of supporting the part to be positioned 10 is improved. In this embodiment, as shown in fig. 4, the second to-be-positioned member 10b has a rectangular sheet structure, and the bottom surface of the second to-be-positioned member 10b has a rectangular shape, and accordingly, the bearing surface 111 has a rectangular surface.

More specifically, the bearing portion 11 further includes a resisting surface 112 perpendicularly connected to one end of the bearing surface 111, and the resisting surface 112 is used for resisting the sidewall of the member to be positioned 10. The provision of the abutment surface 112 further improves the positioning effect on the part to be positioned 10.

Specifically, the bearing surface 111 is provided with a groove 113, the groove 113 divides the bearing surface 111 into two spaced supporting surfaces, and two ends of the to-be-positioned piece 10 are respectively supported on the two supporting surfaces. By the arrangement, the stability of the bearing part 11 for supporting the to-be-positioned piece 10 is ensured, and the displacement of the to-be-positioned piece 10 is prevented from being influenced by too large friction force due to too large contact area of the to-be-positioned piece 10 and the bearing surface 111.

More specifically, the bearing surface 111 is provided with a plurality of positioning posts 12. In this embodiment, as shown in fig. 4, one positioning post 12 is disposed on each of the two supporting surfaces, so that both ends of the second member to be positioned 10b are coarsely positioned.

Specifically, one end of the positioning column 12 facing away from the bearing portion 11 is an introduction head, and the diameter of the introduction head gradually decreases from one end close to the bearing portion 11 to one end far away from the bearing portion 11, so as to facilitate penetration of the positioning column 12 into the to-be-positioned member 10.

Specifically, as shown in fig. 1, the carrying seat 1 is provided with a plurality of carrying portions 11 and a plurality of pairs of positioning pawls 2, and each carrying portion 11 is provided with a pair of positioning pawls 2. The positioning operation efficiency is improved by the arrangement.
