[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] The embodiment of the utility model discloses a terminal pressing mechanism.

[0032] According to the attached Figure 1-7 As shown, it includes an assembly carrier plate 1 and an assembly seat 3 arranged on the top of the assembly carrier plate 1, a pressing component 2 is provided on the top of the assembly seat 3, and the pressing component 2 includes a pressing cylinder 22 and a positioning assembly clamp 23 installed at the bottom end of the pressing cylinder 22;

[0036] The assembly seat 3 includes a fixed support 31 and an automatic clamping seat 32 arranged inside the fixed support 31. The outer side of the automatic clamping seat 32 is movably hinged with a spring clamping arm 33. The bottom end of the spring clamping arm 33 is squeezed against the outer wall of the fixed support 31 to realize the expansion of the spring clamping arm 33.

[0037] A contact roller 34 is fixedly installed on the outer side of the top of the fixed support 31, and the contact roller 34 is against the bottom end of the spring clamp arm 33. A torsion spring is provided between the spring clamp arm 33 and the automatic clamping seat 32, and the torsion spring drives the spring clamp arm 33 to automatically flip toward the middle to clamp the workpiece.

[0038] When waiting for loading, the spring clamp arm 33 is against the contact roller 34 on the top of the fixed support 31, so that multiple spring clamp arms 33 are stretched outward. At this time, the workpiece is inserted into the top of the automatic clamp seat 32, and then the lifting cylinder 45 drives the automatic clamp seat 32 to move up through the square rod 42. At this time, the bottom end of the spring clamp arm 33 is separated from the contact roller 34. At this time, under the action of the torsion spring inside the spring clamp arm 33, the spring clamp arm 33 flips inward and automatically clamps the outer surface of the workpiece, which can realize automatic support during processing. After the processing is completed, the automatic clamp seat 32 automatically stretches out when it moves down, which is low in cost and can avoid excessive clamping force to damage the workpiece.

The side of the positioning assembly clamp 23 is connected to the hydraulic feed pusher 25.

[0041] The hydraulic feed pusher 25 inserts a series of processed terminals into the interior of the positioning assembly clamp 23 from the side. When the terminals are pressed in, the downward pressure cylinder 22 is started, and the output end of the downward pressure cylinder 22 moves downward, driving the entire sliding carrier 24 to move downward. At this time, the wedge-shaped top plate 27 is first inserted to the inner side of the top of the rotating cutting rod 28 and abuts against the cutting roller 210, so that the top of the rotating cutting rod 28 is flipped outward. At this time, the bottom end of the rotating cutting rod 28 drives the cutter 211 to move inward, cutting off the connection part of the terminal, so that the front terminal is separated from the entire string of terminals. At this time, the sliding carrier 24 continues to move downward. At this time, the feed push rod 29 contacts the top of the terminal, pushing the terminal downward, so that the terminal is inserted into the workpiece, completing the terminal insertion operation.
