[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] In order to solve the problem of poor punch adjustment accuracy of terminal machines in the prior art, the present application proposes a punch adjustment mechanism for a terminal machine, wherein an adjusting wheel that is in contact with and can be eccentrically rotated is provided on the top of the cutter body, and the eccentric rotation of the adjusting wheel is utilized to force the cutter body to passively change its position. The adjusting wheel has a high-precision adjustment range when it rotates eccentrically, thereby effectively improving the adjustment accuracy of the cutter body.

[0021] Figure 1 The overall structural diagram of the punch adjustment mechanism of the terminal machine is shown; Figure 2 A schematic cross-sectional view of the punch head 100 is shown; Figure 1 and Figure 2In the present invention, the punch of the terminal machine includes a punch head 100, which has a blade 110 inside, and a blade body 120 is inserted into the blade 110. A locking bolt 130 is rotatably connected to the punch head 100, and the output end of the locking bolt 130 is inserted into the blade 110 and abuts against the blade body 120; the locking bolt 130 is driven to move to a side away from the blade body 120 so that the locking bolt 130 is disengaged from the abutment with the blade body 120, and the blade body 120 is manually pushed to move along the trajectory of the blade 110 to adjust to a desired position. After the adjustment is completed, the locking bolt 130 is driven to abut against the blade body 120 again to complete the adjustment of the blade body 120; however, during the adjustment process, it is difficult to control the force of manually pushing the blade body 120, which makes it difficult for the blade body 120 to be in the position the adjuster wants it to be.

[0022] In view of the above technical problems, the present application provides a punch adjustment mechanism for a terminal machine. Figure 3 A schematic cross-sectional view of a punch adjustment mechanism of a terminal machine is shown; Figure 4 shows a schematic structural diagram of the adjustment mechanism 200; Figure 3 and Figure 4 In the embodiment, the punch adjustment mechanism of the terminal machine is installed on the punch head 100 and arranged above the knife body 120. The adjustment mechanism 200 includes a rotating rod 210 rotatably connected to the punch head 100. One end of the rotating rod 210 extends into the punch head 100 and is eccentrically connected to an adjusting wheel 220. The outer wall of the adjusting wheel 220 is in conflict with the knife body 120. Since the adjusting wheel 220 can rotate eccentrically around the rotating rod 210 and the adjusting wheel 220 is in contact with the knife body 120, when adjusting the height of the knife body 120, the knife body 120 can be supported by one hand and the adjusting wheel 220 can be driven by the other hand to rotate eccentrically around the rotating rod 210, so as to achieve high-precision fine adjustment of the height of the knife body 120. The other end of the rotating rod 210 One end of the observation wheel 230 extends to the outside of the punch head 100 and is connected to the corresponding adjustment wheel 220; the correspondence between the adjustment wheel 220 and the observation wheel 230 here refers to the same rotation angle, and the operator can observe the situation of the adjustment wheel 220 in real time from the outside to determine the rotation direction as needed; a gasket 240 is connected to the end face of the observation wheel 230 facing the punch head 100, and the gasket 240 is in contact with the punch head 100; the gasket 240 can form a damping effect between the observation wheel 230 and the punch head 100, that is, to ensure that the observation wheel 230 does not shake during the stamping process under normal conditions, and the gasket 240 is deformable, and still allows the observation wheel 230 to rotate relative to the punch head 100.

[0023] Figure 5The schematic diagram of the structure of the extrusion mechanism 300 is shown; the extrusion mechanism 300 is arranged on both sides of the blade body 120, and the extrusion mechanism 300 includes a cavity 310 opened in the punch head 100, a spring 320 is connected in the cavity 310, a ball 330 is movably arranged in the cavity 310, and the spring 320 is in a compressed state and squeezes the ball 330 to contact the blade body 120; since the balls 330 on both sides of the blade body 120 can continuously squeeze the blade body 120, the possibility of deviation of the blade body 120 during the stamping process can be reduced, and since the balls 330 can roll along the surface of the blade body 120, when the blade body 120 is adjusted, the blade body 120 is still allowed to move relative to the balls 330, so that the height of the blade body 120 can be adjusted.

[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
