The first driving assembly 301 can make the first pressing head 3031 and the second pressing head 3032 press down along the first direction to press the bar 2 into the receiving groove 11 of the workpiece 1. On the one hand, due to the different diameters of the first pressing head 3031 and the second pressing head 3032, the pressing of bars 2 of different thicknesses can be satisfied.

After the bar material 2 is placed in the pre-storage bin 203, the position of the pre-storage bin 203 can be adjusted by the third drive assembly 201 and the fourth drive assembly 202, so that the pre-storage bin 203 is close to the workpiece 1 on the positioning fixture 102, so that the discharge port of the discharge channel 2031 of the pre-storage bin 203 is aligned with the notch of the receiving groove 11 of the workpiece 1. Exemplarily, the third drive assembly 201 and the fourth drive assembly 202 can be cylinders or screw nut mechanisms.

[0050] Optionally, a detection component 207 is provided in the pre-storage bin 203, and the detection component 207 may be, but is not limited to, a group of through-beam sensors, which are used to determine whether the bar material 2 is placed in the discharge channel 2031 of the pre-storage bin 203. The feeding unit 200 further includes a second cylinder 204, the fixed end of the second cylinder 204 is arranged at the movable end of the fourth driving component 202, and the movable end of the second cylinder 204 is provided with a retaining edge 2041, and the retaining edge 2041 is used to close or open the discharge channel 2031 of the pre-storage bin 203.

When the double pressing head 303 applies downward pressure to the workpiece 1, the impact force from the pressing head can be buffered by adding the spring 1023, and when the pressure of the double pressing head 303 is too large, the positioning fixing seat 1022 can also move downward.

[0053] Furthermore, a support block 500 is provided on the base 404 of the frame 400, and the support block 500 is located directly below the positioning and fixing seat 1022.

A clamping cylinder 600 is provided on the vertical beam 403 of the frame 400. The clamping cylinder 600 can assist in positioning the upper half of the workpiece 1. Optionally, the clamping cylinder 600 is assembled to the bracket through a first mounting plate 601 and a second mounting plate 602, wherein a waist-shaped hole is provided on the first mounting plate 601 for adjusting the position of the clamping cylinder 600.

[0054] The working principle of the press-fitting mechanism in this embodiment is as follows: the lower half of the workpiece 1 is placed on the positioning and fixing seat 1022 of the positioning fixture 102, and the positioning and fixing seat 1022 is used to locate the position of the workpiece 1. The upper half of the workpiece 1 is tightened by the clamping claw cylinder 600 to clamp the workpiece 1. The bar 2 reaches the discharge channel 2031 of the pre-storage bin 203 from the feeding channel of the transparent discharge tube 206. When the bar 2 reaches the discharge port below the discharge channel 2031, the sensor of the detection component 207 detects whether the bar 2 is delivered in place. Before this, the second cylinder 204 remains in an extended state to pre-store the bar 2, while the third drive component 201 is in an extended state, and the fourth drive component 202 is also extended and fits the workpiece 1. The pressing electric cylinder 3011 drives the connected double pressing heads 303 to perform lifting activities (in order to make the lifting activities of the pressing electric cylinder 3011 more stable, a guide column 3015 is connected above the fixed plate 3012, and the guide column 3015 is movably connected to the first crossbeam 401 of the frame 400 through the first linear bearing 405). The first pre-pressing: the first cylinder 3021 cooperates with the linear guide rail 3013 to slide (the limit block 3014 is installed on the fixed plate 3012 to prevent the first cylinder 3021 from extending beyond a preset range). The first pressing head 3031 and the discharge port of the bar 2 of the pre-storage bin 203 are kept in the same straight line. The pressing electric cylinder 3011 is pressed down, and the first pressing head 3031 passes through the discharge channel 2031 to perform the first pre-pressing work on the bar 2, so that the bar 2 is pressed into the bottom of the receiving groove 11 of the workpiece 1 (after completion, the pressing electric cylinder 3011 retracts, and the third driving assembly 201 retracts). The second press-fitting: the first air cylinder 3021 slides in cooperation with the linear guide rail 3013 to keep the second pressing head 3032 and the bar 2 in the same straight line. The pressing cylinder 3011 is pressed down, and the second pressing head 3032 squeezes the end of the bar 2. The bar 2 in the receiving groove 11 is squeezed and deformed to fit closely to the inner wall of the receiving groove 11, and the press-fitting is completed. The bar 2 in the receiving groove 11 of the workpiece 1 is filled and pressed, and the bar 2 outside the receiving groove 11 is collapsed and flanging. The pressing cylinder 3011 retracts (a pressure sensor 304 is installed above the double pressing head 303), and the pressure value is detected during the press-fitting process to determine whether the press-fitting is in place. In addition, when pressing down, the transmission of the pressing force is achieved by installing an elastic structure (spring 1023) and the support block 500 is installed to bear the load. When not pressing, the spring force of the spring 1023 is used to move the positioning fixing seat 1022 upward and away from the end surface of the support block 500, thereby avoiding scratches when the rotating table panel 101 rotates.
