Specifically, the first station 1 is a position reached after the rotating block 80 rotates a certain angle in the fourth direction N from the second station 2, and the second station 2 is a position reached after the rotating block 80 rotates a certain angle in the fifth direction S from the first station 1, and the fourth direction N is coaxial with and has opposite rotation direction to the fifth direction S. The first end 71 is hinged to the rotating block 80, and when the rotating block 80 rotates under the action of the first end 71, the turntable 20 rotates synchronously with the rotating block 80.

When the push-pull assembly 50 pushes the locking block 60 to slide towards the rotary table 20, the second end portion 72 abuts against the transition groove 613, so that when the locking block 60 is pushed to slide, the groove wall of the transition groove 613 pushes the second end portion 72 to slide, and when the rotary block 80 just rotates to the first station 1 along the fourth direction N, the second end portion 72 just enters the first chute 611 from the transition groove 613 under force. When the push-pull assembly 50 pushes the locking block 60 to slide towards the rotary table 20, the second end portion 72 abuts against the transition groove 613, so that when the locking block 60 is pushed to slide, the groove wall of the transition groove 613 pushes the second end portion 72 to slide, and when the rotary block 80 just rotates to the second station 2 along the fifth direction S, the second end portion 72 just enters the second sliding groove 612 from the transition groove 613 under force.

Of course, the structures and dimensions of the first chute 611 and the second chute 612 may be different, and in this case, the rotation angles of the turntable 20 in the fourth direction N and the fifth direction S are different, so that multi-angle rotation adjustment may be achieved.

Further, the first cavity 161 is communicated with the second cavity 162, and is disposed along the first direction X, and the connection block 70 is movably disposed in the first cavity 161 along the horizontal direction. When the push-pull assembly 50 pushes the locking block 60 to slide in the first cavity 161 along the first direction X, the locking block 60 drives the connecting block 70 to slide in the sliding groove 61, so that the connecting block 70 drives the rotating block 80 to rotate, and the rotating block 80 drives the turntable 20 to synchronously rotate around its own axis.
Referring to fig. 4 again, the sliding grooves 61 are arranged in two groups, the two groups of sliding grooves 61 are arranged in parallel along the third direction Z, and a cavity 64 for the second end 72 to move is formed between the two groups of sliding grooves 61, the second end 72 is provided with a latch 73 along the third direction Z, and two ends of the latch 73 are respectively slidably arranged in the two groups of sliding grooves 61.

The bolt 73 is in a columnar structure, the outer diameter of the bolt 73 is matched with the inner diameters of the first chute 611 and the second chute 612, so that the bolt 73 is driven to slide along the first chute 611 and the second chute 612 by the supporting action of the groove walls of the first chute 611 and the second chute 612 on the bolt 73, and the bolt 73 further drives the second end 72 to slide along the first chute 611 and the second chute 612. The sliding grooves 61 are provided in two groups so as to accommodate both ends of the pins 73, respectively, ensuring the sliding accuracy of the pins 73.

In an embodiment, when the rotary block 80 drives the rotary table 20 to rotate to the first station 1 or the second station 2, the second limiting structure 63 and the first limiting structure 164 relatively fix the rotary block 80 in the mounting cavity 16, so as to lock the rotary table 20, and prevent the deflection of the rotary table 20 during the processing from affecting the processing precision.
Further, the rotating block 80 includes a connecting protrusion 81, the connecting protrusion 81 is configured to hinge with the first end 71, and includes a first end surface 811 and a second end surface 812, the first end surface 811 movably abuts against a first abutting structure 1641, and the second end surface 812 movably abuts against a second abutting structure 1642. In an embodiment, the second limiting structure 63 is used for limiting the second end 72 of the connecting block 70, the first limiting structure 164 is used for limiting the rotating block 80, and then limiting the first end 71 of the connecting block 70, so that the two ends of the connecting block 70 are limited and then the connecting block 70 is locked, and when the connecting block 70 is locked, one side of the rotating block 80 is abutted by the locked connecting block 70, and the other side is abutted by the second limiting structure, so that the rotating block 80 is locked.
When some embodiments are adopted, the outer ends of the connecting protrusions 81 are arranged in an arc-shaped structure and are hinged with the first end portions 71, and the first abutting structure 1641 and the second abutting structure 1642 are used for abutting against the connecting protrusions 81, so that the rotation of the rotating block 80 is limited. A slot accommodating the first end portion 71 is formed in a side of the connection protrusion 81 near the first end portion 71, and hinge holes through which the hinge shaft 82 passes are formed in both the connection protrusion 81 and the first end portion 71 in the third direction Z.
The second cavity 162 is a semicircular structure, and the first abutting structure 1641 and the second abutting structure 1642 are respectively disposed at the connection positions of the two ends of the first cavity 161 and the second cavity 162. And the first abutment structure 1641 and the second abutment structure 1642 are each inclined-surface structures facing the connection protrusion 81.
The second limiting structure 63 includes a first curved surface structure 631 and a second curved surface structure 632, the first curved surface structure 631 and the second curved surface structure 632 are both disposed on one side of the second end 72 away from the first end 71 and are bent towards the second end 72, the first curved surface structure 631 is disposed at a connection position between the first chute 611 and the transition groove 613, and the second curved surface structure 632 is disposed at a connection position between the second chute 612 and the transition groove 613.
When some embodiments are used, the connection between the first curved surface structure 631 and the first sliding groove 611 and the transition groove 613 is smoothly transited, so as to ensure that the latch 73 can smoothly pass through the first curved surface structure 631. Meanwhile, when the latch 73 is to slide into the first chute 611 from the transition groove 613, the first curved surface structure 631 blocks the latch 73 from sliding. Until the rotating block 80 rotates to the first station 1 along the fourth direction N, the push-pull assembly 50 continues to push the locking block 60 to move, the first end surface 811 of the rotating block 80 is resisted by the first abutting structure 1641 and cannot rotate continuously, the rotating block 80 further resists the movement trend of the first end portion 71 hinged with the rotating block towards the rotating block 80, the second end portion 72 continues to be acted by the thrust of the groove wall of the transition groove 613, so that the connecting block 70 generates the rotation trend along the fifth direction S, and when the thrust of the groove wall of the transition groove 613 against the second end portion 72 overcomes the resistance of the first curved surface structure 631 against the bolt 73, the second end portion 72 passes through the first curved surface structure 631 and then enters the first sliding groove 611. At this time, the first curved surface structure 631 will block the sliding trend of the second end 72 toward the transition groove 613, so that the connecting block 70 will block the rotation of the locking block 60 in the fifth direction S, i.e. will block the rotation of the turntable 20 in the fifth direction S, while the first abutting structure 1641 will block the rotation of the turntable 20 located at the first station 1 in the fourth direction N, so as to lock the turntable 20 at the first station 1 after being completely limited. The second curved surface structure 632 and the second abutting structure 1642 have the same structure and principle as the first curved surface structure 631 and the first abutting structure 1641, and are not described in detail.
