Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 shows a first workpiece 20 positioned according to an embodiment of the present disclosure, specifically, the first workpiece 20 has a side wall 21 and a top wall 22. In an embodiment, the first workpiece 20 may be a small piece, such as a camera ring and a bracket for a 3C electronic product, which need to be assembled, and the positioning device 10 of the present invention may be used to position the first workpiece 20, and then place other components, such as a middle plate, on the positioning device 10 for fixing, and then weld the two components.

Referring to fig. 2 to 4, the positioning device 10 includes a bearing assembly 11 and a positioning assembly 12, the bearing assembly 11 includes a pressing member 111 and a bearing member 112, the positioning assembly 12 is disposed on one side of the bearing member 112 facing the pressing member 111, the positioning assembly 12 includes a positioning member 121 and a supporting member 122, the positioning member 121 is used for bearing and primarily positioning the first workpiece 20, one end of the supporting member 122 is rotatably connected to the positioning member 121, and the other end of the supporting member 122 is rotated under the pushing of the pressing member 111 and supported on the side wall 21 of the first workpiece 20, so as to cooperate with the positioning member 121 to position the first workpiece 20. Illustratively, the first workpiece 20 may be a tiny component in a cell phone.

When the positioning device 10 operates, the first workpiece 20 is firstly placed on the positioning element 121, so that the positioning element 121 is used to carry the first workpiece 20 and perform preliminary positioning on the first workpiece 20, then the pressing element 111 is installed on the carrying element 112, the pressing element 111 pushes the abutting element 122 in the installation process to rotate the abutting element 122 until the abutting element 122 abuts against the side wall 21 of the first workpiece 20 towards one end of the first workpiece 20, and at this time, the positioning element 121 and the abutting element 122 are matched and clamp the first workpiece 20, so that the angle of the first workpiece 20 cannot deflect and the position of the first workpiece 20 cannot move. Thus, the pressing member 111 pushes the abutting member 122 to rotate, and pushes the side wall 21 of the first workpiece 20 to abut against the positioning member 121, and the first workpiece 20 is fixed on the positioning member 121 under the clamping of the abutting member 122 and the positioning member 121, thereby avoiding the deviation of the first workpiece 20 during positioning and improving the positioning accuracy of the first workpiece 20.

In an embodiment, the first workpiece 20 includes a circular through hole 23, and the positioning element 121 is a cylinder and is sleeved on the positioning element 121 through the circular through hole 23 of the first workpiece 20, so that the first workpiece 20 can only rotate around the positioning element 121 and cannot translate, which is called as initial positioning of the positioning element 121 on the first workpiece 20.

Referring to fig. 3 and fig. 4, in some embodiments, a guide groove 14 is formed on a side of the supporting member 112 facing the pressing member 111, and the abutting member 122 and the positioning member 121 are disposed in the guide groove 14.

Thus, by accommodating the abutting part 122 and the positioning part 121 of the positioning component 12 in the guide groove 14, the risk of scratching and touching the positioning component 12 is reduced, and the service life of the positioning component 12 is prolonged.

Referring to fig. 4 and fig. 5, in some embodiments, the positioning element 121 includes a movable body 1212 and a positioning body 1211, one end of the movable body 1212 is disposed in the guide slot 14, and the other end of the movable body 1212 extends out of the guide slot 14, one end of the abutting member 122 is rotatably connected to the other end of the movable body 1212, the positioning body 1211 is connected to the other end of the movable body 1212 and located on the same side of the movable body 1212 as the abutting member 122, and the first workpiece 20 is sleeved on the positioning body 1211. The positioning body 1211 can be a positioning pin, and accordingly, the first workpiece 20 has a circular through hole 23 adapted to the positioning pin.

Thus, when positioning the first workpiece 20, the first workpiece 20 is directly sleeved on the positioning body 1211, so as to achieve a fast initial positioning of the first workpiece 20.

In some embodiments, the abutting member 122 includes an abutting body 1221 and an elastic body 1222, one end of the abutting body 1221 is rotatably connected to the movable body 1212 and is located at the same side of the movable body 1212 as the positioning body 1211, one end of the elastic body 1222 abuts against the movable body 1212, the other end of the elastic body 1222 abuts against the abutting body 1221, the other end of the abutting body 1221 is rotated to abut against the side wall 21 of the first workpiece 20 under the pushing of the pressing member 111, and drives the abutting body 1221 to compress the elastic body 1222, and when the pressing member 111 is separated from the abutting body 1221, the elastic body 1222 releases the elastic force and pushes the abutting body 1221 to reset. Illustratively, the elastomer 1222 is a spring.

Thus, when the first workpiece 20 is positioned in the anti-deviation manner, the pressing member 111 pushes the abutting body 1221 and makes the abutting body 1221 abut against the side wall 21 of the first workpiece 20, so as to fix the first workpiece 20, and the anti-deviation positioning of the first workpiece 20 is achieved, at this time, the elastic body 1222 is compressed, after the first workpiece 20 is machined, the pressing member 111 is detached from the bearing member 112 and is made to be away from the bearing member 112, at this time, the elastic body 1222 pushes the abutting body 1221 to be reset by the released elastic force, so that the abutting body 1221 is made to be away from the first workpiece 20, so that a product formed by machining the first workpiece 20 onto the second workpiece is taken out of the bearing member 112.

Referring to fig. 5, in some embodiments, a receiving groove 1213 is formed on a side of the movable body 1212 facing the pressing element 111, and the elastic body 1222 is received in the receiving groove 1213 and abuts against a bottom wall of the receiving groove 1213.

As described above, by accommodating the elastic body 1222 in the accommodating groove 1213, the accommodating groove 1213 accommodates and limits the elastic body 1222 so that the elastic body 1222 can expand and contract in the extending direction of the accommodating groove 1213 and cannot move in other directions, thereby improving the stability of the elastic body 1222 during the expansion and contraction movement.

Referring to fig. 3, fig. 6 and fig. 7, in some embodiments, the supporting member 112 includes a supporting plate 1121 and a substrate 1122, the supporting plate 1121 is used for supporting a second workpiece and is covered on the connecting substrate 1122, the supporting plate 1121 and the substrate 1122 enclose to form an accommodating slot 15 communicated with the guiding slot 14, the positioning device 10 further includes a driving component 13, the driving component 13 passes through the accommodating slot 15 to connect the positioning component 12, and is used for driving the positioning component 12 to drive the first workpiece 20 on the positioning component 12 to abut against the second workpiece and drive the second workpiece to abut against the pressing component 111. For example, the second workpiece may be a mobile phone component that needs to be fixed with the first workpiece 20, and the processing manner between the first workpiece 20 and the second workpiece may be welding or bonding.

Therefore, when the first workpiece 20 and the second workpiece are both installed on the positioning device 10, the driving assembly 13 drives the positioning assembly 12 to further drive the first workpiece 20 on the positioning assembly 12 to move towards the second workpiece and drive the second workpiece to abut against the pressing member 111, so that the top wall 22 of the first workpiece 20 abuts against the second workpiece, the first workpiece 20 and the second workpiece are fixed on the pressing member 111, and the machining precision between the first workpiece 20 and the second workpiece is improved.

Referring to fig. 6 and fig. 7, in some embodiments, the driving element 13 includes a connecting element 131, an eccentric shaft 132, a restoring element 133 and a rotating handle 134, the fixed connecting element 131 is connected to a side of the positioning element 12 away from the second workpiece and is floatingly accommodated in the accommodating slot 15, the eccentric shaft 132 is accommodated in the accommodating slot 15 and abuts against a side of the connecting element 131 facing the positioning element 12, two ends of the eccentric shaft 132 are rotatably connected to the supporting plate 1121, the restoring element 133 is accommodated in the accommodating slot 15, two ends of the restoring element 133 abut against the connecting element 131 and the supporting plate 1121 respectively, and the rotating handle 134 is disposed outside the accommodating slot 15 and connected to one end of the eccentric shaft 132 for driving the eccentric shaft 132 to rotate. Illustratively, the restoring member 133 may be a spring.

When the driving assembly 13 is in operation, an operator rotates the rotating handle 134, the rotating handle 134 drives the eccentric shaft 132 to rotate together, the eccentric shaft 132 drives the connecting piece 131 to move in the vertical direction in the rotating process, when one side of the eccentric shaft 132 close to the rotating shaft of the eccentric shaft abuts against the connecting piece 131, the reset piece 133 releases the elastic force and drives the connecting piece 131 to move towards the second workpiece, and the connecting piece 131 drives the positioning assembly 12 and the first workpiece 20 thereon to move towards the second workpiece in the vertical direction, so that the second workpiece is pushed by the first workpiece 20 until the second workpiece abuts against the pressing piece 111, and further the first workpiece 20 abuts against the second workpiece and is positioned on the second workpiece.

Referring to fig. 6, in some embodiments, the bearing member 112 and the connecting member 131 are provided with a through hole 19 at a position corresponding to the positioning assembly 12, so that a workpiece can pass through the through hole 19 to machine the first workpiece 20 onto the second workpiece. Illustratively, the workpiece may be a welder.

Therefore, when the first workpiece 20 is welded to the second workpiece, the welding part of the welding machine extends into the machining through hole 19 to a position close to the first workpiece 20, the machining through hole 19 reserves a machining space for a machined part, and the convenience of welding operation is improved.
