In order to keep the workpiece in a preset position relative to the positioning seat 12 when the workpiece is placed, limit blocks 1222 are arranged on the two opposite sides of the receiving groove 1221 in a direction perpendicular to the first rotating shaft 14. The limit blocks 1222 cooperate with the receiving groove 1221 to form a limit space for limiting the workpiece. It can be understood that the groove walls on the two sides of the receiving groove 1221 in the extension direction of the first rotating shaft 14 are arranged in a shape following the workpiece, so as to improve the limiting capability of the workpiece.

[0035] Continuing to refer to Figure 4 The first elastic member 16 includes a spring, one end of the spring is connected to the fixed seat 11, and the other end is connected to the first rotating shaft 14 and then connected to the positioning seat 12.

As for the specific shape of the clamping part, especially the width of the clamping part along the direction of the second rotation shaft 15, it is adjusted adaptively according to different models of workpieces to avoid affecting the machining of the workpiece.

[0037] In order to improve the clamping force, the clamping arm 131 is provided with two, and the two clamping arms 131 are arranged on the opposite sides of the positioning seat 12 along the extension direction of the first rotation shaft 14. Obviously, the rotating directions of the two clamping arms 131 are opposite, so as to clamp the opposite sides of the workpiece along the extension direction of the first rotation shaft 14 at the same time.

[0038] Optionally, the clamping force of the clamping arm 131 on the workpiece can come from a clamping driving part, the output end of the clamping driving part is connected with the clamping arm 131, so that the cantilever end of the clamping arm 131, i.e. the end far away from the second rotation shaft 15, moves towards the positioning seat 12 or away from the positioning seat 12, so as to clamp or release the workpiece.

[0039] In an embodiment, the clamping assembly 13 includes a second elastic part 132 configured to apply an elastic force to the clamping arm 131, so that the cantilever end of the clamping arm 131 has a tendency to rotate towards the positioning seat 12, thereby clamping the workpiece. On this basis, the carrier 10 needs to cooperate with an external unlocking mechanism 50, and the unlocking mechanism 50 can apply a force to the clamping arm 131 to overcome the elastic force of the second elastic part 132, so that the cantilever end of the clamping arm 131 moves away from the positioning seat 12. Specifically, the second elastic part 132 adopts a torsional spring, and the torsional spring is sleeved on the second rotation shaft 15 and connected with the clamping arm 131.

When the first limiting part rotates to abut against the second limiting part, the positioning seat 12 stops rotating due to the limitation of the second limiting part, and the positioning seat 12 is in a preset second machining position. The positioning seat 12 further includes a first machining position, which specifies the position of the workpiece when the positioning seat 12 is in the initial position.

[0041] The multi-station rotary table further includes an unlocking mechanism 50, the unlocking mechanism 50 is configured to drive the cantilever end of the clamping arm 131 to move away from the positioning seat 12, so as to release the workpiece or facilitate the placement of the workpiece on the positioning seat 12.
