[0044] Please refer to Figure 3 and Figure 4The positioning jig 6 comprises a bottom plate 61, a mounting plate 62, a bearing plate 63, a driving assembly 64, a supporting column 65 and a positioning piece 66. The bottom plate 61 is fixedly arranged on the upper end surface of the machine table 1. The supporting column 65 is arranged between the bottom plate 61 and the bearing plate 63. The bottom plate 61 is fixedly arranged on the machine table 1 through the supporting column 65. The mounting plate 62 is parallel to the bearing plate 63 and is fixedly arranged on the upper end surface of the bearing plate 63. The mounting plate 62 is provided with a notch groove 622 for placing a workpiece. The length direction of the positioning piece 66 and the notch groove 622 is the same as the length direction of the mounting plate 62. The positioning piece 66 is arranged on one side of the opening of the notch groove 622. The driving assembly 64 drives the positioning piece 66 to move towards the notch groove 622, so as to enclose the opening of the notch groove 622 and press the workpiece to the inside of the notch groove 622. In this embodiment, the notch groove 622 and the positioning piece 66 are provided with two groups. The mounting plate 62 is provided with an avoiding groove 623. The length direction of the avoiding groove 623 is the same as the length direction of the positioning piece 66. The avoiding groove 623 is located between the two positioning pieces 66. The driving assembly 64 is arranged in the avoiding groove 623. The driving assembly 64 drives the two positioning pieces 66 to move towards the notch groove 622 at the same time, so as to position two workpieces synchronously.

[0045] Specifically, please refer to Figure 4 and Figure 5The driving assembly 64 comprises a sliding block 641, a first connecting rod 642, a second connecting rod 643 and a lifting driving member 644. The first connecting rod 642 is vertically arranged, the second connecting rod 643 is transversely arranged, and the lifting driving member 644 is fixedly arranged on the bottom plate 61. The sliding block 641 is connected with one end of the first connecting rod 642, and the sliding block 641 is slidably connected with the positioning member 66. The length direction of the sliding block 641 is the same as the length direction of the positioning member 66. The first connecting rod 642 is slidably connected with the bearing plate 63. The lifting driving member 644 drives the first connecting rod 642 to drive the sliding block 641 to move up and down to slide and push the positioning member 66, so that the positioning member 66 pushes the workpiece to the side of the gap groove 622. Specifically, an end face of the sliding block 641 facing the positioning member 66 is provided with a first inclined surface 6411. The lower end of the first inclined surface 6411 is inclined toward the central axis of the first connecting rod 642. That is, the straight line distance between the upper end of the first inclined surface 6411 and the central axis of the first connecting rod 642 is greater than the straight line distance between the lower end of the first inclined surface 6411 and the central axis of the first connecting rod 642. The first inclined surface 6411 is in sliding contact with and abuts against the positioning member 66. An end face of the positioning member 66 facing the sliding block 641 is provided with a second inclined surface 661. The first inclined surface 6411 and the second inclined surface 661 are slidably connected to push the positioning member 66. It can be understood that the lifting driving member 644 drives the first connecting rod 642 to move downward, and the first connecting rod 642 drives the sliding block 641 to move downward synchronously. The first inclined surface 6411 abuts against the second inclined surface 661 to drive the positioning member 66 to move toward the gap groove 622. The purpose is to realize the positioning of the workpiece by surrounding the gap groove 622 with the side wall of the positioning member 66 and pushing the workpiece to the inside of the gap groove 622.

[0046] In the embodiment, the positioning member 66 is preferably a spring piece. The cross section of the positioning member 66 is arranged in the shape of a “T” character. The positioning member 66 comprises a pressing portion 662 arranged transversely and a connecting portion 663 arranged vertically. The pressing portion 662 and the connecting portion 663 are integrally formed. The second inclined surface 661 is the right side surface of the pressing portion 662. One end of the connecting portion 663 away from the pressing portion 662 is fixedly connected with the bearing plate 63. The thickness of the connecting portion 663 is smaller than the thickness of the pressing portion 662. When the sliding block 641 abuts against the pressing portion 662, the force acting on the pressing portion 662 is transmitted to the connecting portion 663. The connecting portion 663 is more likely to deform and bend, so that the pressing portion 662 gradually approaches the gap groove 622 to push the workpiece.

[0047] One end of the second connecting rod 643 is rotatably connected with the output end of the lifting driving member 644, and the other end of the second connecting rod 643 is rotatably connected with one end of the first connecting rod 642 away from the sliding block 641. The one end of the second connecting rod 643 close to the first connecting rod 642 is provided with a connecting hole 6431. The support column 65 is fixedly provided with a connecting shaft 651 which penetrates through the connecting hole 6431 and is rotatably connected with the second connecting rod 643. In the embodiment, the lifting driving member 644 is preferably a pneumatic cylinder, the connecting hole 6431 is a waist-shaped hole, the first connecting rod and the second connecting rod are connected through the hole shaft, and the waist-shaped connecting hole 6431 provides space for the rotation of the second connecting rod 643. It can be understood that when the output end of the lifting driving member 644 is extended, the second connecting rod 643 rotates around the connecting shaft 651 as the rotation center, the one end of the second connecting rod 643 away from the first connecting rod 642 moves upward, and the one end of the second connecting rod 643 close to the first connecting rod 642 moves downward. At this time, the first connecting rod 642 also moves downward, and the movement of the first connecting rod 642 synchronously drives the movement of the sliding block 641. The sliding block 641 moves downward to press the positioning member 66 to move towards the direction of the notch groove 622 to enclose the notch groove 622 to laterally press the workpiece. The positioned workpiece is convenient for the machining mechanism 4 to process the workpiece. After the machining is completed, the output end of the lifting driving member 644 is controlled to be retracted, the second connecting rod 643 rotates around the connecting shaft 651 as the rotation center, the one end of the second connecting rod 643 away from the first connecting rod 642 moves downward, and the one end of the second connecting rod 643 close to the first connecting rod 642 moves upward. At this time, the first connecting rod 642 also moves upward, and the movement of the first connecting rod 642 synchronously drives the movement of the sliding block 641. The sliding block 641 moves upward to contact the pressing of the positioning member 66. The positioning member 66 resets towards the direction away from the notch groove 622. The positioning member 66 releases the positioning of the workpiece, and the clamping mechanism 3 clamps the workpiece to be transferred to the material collecting box 7.
