[0132] Specifically, the push elastic member 143 is a spring. Before placing the product 600 on the bearing seat 11, the stopper 144 is pushed into the limiting portion 1412a. At this time, the stopper 144 cooperates with the limiting portion 1412a to limit the push member 142 from moving in the first direction. The push member 142 is away from the first limiting block 12 and the push elastic member 143 is compressed, so that it is convenient to place the product 600 between the first limiting block 12 and the push member 142. When the product 600 needs to be positioned, the stopper 144 is pushed into the limiting portion 1412a. The stopper 144 slides into the guide portion 1412b. Since the guide portion 1412b extends along the first direction, the stopper 144 is no longer restricted. The push elastic member 143 drives the push member 142 to move toward the first limit block 12 and presses the product 600 against the first limit block 12. The guide portion 1412b and the stopper 144 cooperate to limit the moving direction and distance of the push member 142, which is beneficial to improve the accuracy of the push member 142 in pressing and positioning the product 600 along the first direction.

Among them, the extrusion elastic member 152 can be a spring. Before placing the product 600 on the bearing seat 11, the extrusion member 151 is pulled away from the bearing seat 11 along the third direction, so as to avoid the product 600 when placing the product 600. When it is necessary to position the product 600, the extrusion member 151 is released, and the extrusion elastic member 152 drives the extrusion member 151 to press and position the product 600 along the third direction. In this way, it is conducive to improving the convenience of using the extrusion assembly 15 to press and position the product 600 along the third direction.

[0135] In this embodiment, the extrusion assembly 15 also includes a first connecting member 153 and a second connecting member 154.

When the positioning assembly 22 and the clamping assembly 23 cooperate to position the workpiece 700 along the first direction, the workpiece 700 is first placed on the support protrusion 2221, and the pushing elastic member 224 drives the pushing unit 223 to push the workpiece 700 to move on the support protrusion 2221 along the first direction, and then the locking member 225 is moved to engage with the locking groove 2231a, and the locking member 225 limits the distance that the pushing unit 223 pushes the workpiece 700 to move on the support protrusion 2221. Finally, the clamping assembly 23 presses the workpiece 700 against the pushing unit 223 along the first direction, and the tensioning elastic member 227 drives the cover pressing member 226 to press the workpiece 700 against the support protrusion 2221 along the third direction. In this way, by setting the pushing elastic member 224 to drive the pushing unit 223 to push the workpiece 700 to move on the support protrusion 2221 along the first direction, and by setting the locking member 225 and the locking groove 2231a to limit the distance that the pushing unit 223 pushes the workpiece 700 to move on the support protrusion 2221, it is ensured that when the clamping assembly 23 clamps the workpiece 700, the relative position of the workpiece 700 and the assembly part 610 of the product 600 in the first direction is unique, which is beneficial to improve the accuracy of the positioning assembly 22 and the clamping assembly 23 in positioning the workpiece 700 along the first direction; in addition, by setting the tensioning elastic member 227 to drive the cover pressing member 226 to press the workpiece 700 against the support protrusion 2221 along the third direction, it is beneficial to reduce the probability of relative movement of the workpiece 700 relative to the assembly part 610 of the product 600 when assembling the workpiece 700, which is beneficial to improve the assembly accuracy of the workpiece 700.

[0141] In this embodiment, the positioning assembly 22 further includes a pull bolt 228 . The pull bolt 228 is disposed on a side of the cover pressing member 226 away from the positioning seat 222 .

Specifically, as Figure 3 As shown, a through hole 620 communicating with the assembly portion 610 is provided on the side of the product 600 facing the pressing member 231. The pressing member 231 passes through the through hole 620 and presses the workpiece 700 under the drive of the pressing elastic member 232.
