A pin rod 614 is movably provided on the limit frame 609. A clamping block 615 is fixedly provided on the outside of the pin rod 614. The locking frame 612 includes a locking rod and a locking hook. The inclined surfaces are provided on the sides of the locking hook and the clamping block 615 close to each other. The inclined surface on one side of the locking hook is parallel to the inclined surface on one side of the clamping block 615. The setting of the balance support structure 6 can provide support for the ram, not only ensuring the balance during the movement of the ram, but also replacing the traditional method of setting balance blocks on one side, effectively preventing the situation that the ram is deformed due to uneven force on one side and excessive weight on one side;

[0029] Referring to Figure 4 , To achieve the blocking purpose, positioning shafts 603 are fixedly provided at both ends of the mounting seat 601. A baffle 604 is movably provided on the positioning shafts 603. A round hole is provided on the baffle 604. A bearing is fixedly provided in the round hole.

[0030] Working principle: When using the device, first install the balance support structure 6 between the ram body 3 and the column 1. Install the mounting seat 601 on one side of the column 1 through bolts. Then rotate the baffle 604 clockwise by 90 degrees. Next, insert the insert bar 605 into the slot on one side of the mounting seat 601. Then rotate the baffle 604 counterclockwise by 90 degrees to make it fit with the insert bar 605 to complete the installation of the limit seat 602. Then, clamp the locking seat 608 on the limit plate 604. Then push the pin rod 614. The pin rod 614 drives the block 615. The block 615 fits with the lock frame 612. When the inclined surface on one side of the lock frame 612 is disengaged from the inclined surface on one side of the block 615, the first spring pushes the lock frame 612 to make it clamp on the block 615. At this time, one end of the pin rod 614 passes through the pin hole on the limit plate 4, and the installation of the balance support structure 6 is completed. During the operation of the device, the balance support structure 6 can provide support for the ram, ensure the balance of the ram during operation, and prevent the situation that the ram is deformed due to uneven force on one side and excessive weight on one side. When it is necessary to disassemble the balance support structure 6, first squeeze the ejector rod 613. The ejector rod 613 squeezes the lock frame 612 to make it disengage from the block 615. Then pull the pin rod 614 outwards. When the pin rod 614 is disengaged from the pin hole, rotate the support rod 607 to drive the locking seat 608 to rotate. When the locking seat 608 is completely disengaged from the limit plate 4, then rotate the baffle 604 by 90 degrees to make it disengage from the fit with the insert bar 605. Finally, pull the limit seat 602 outwards to remove the limit seat 602 from the mounting seat 601 and replace or maintain the components in this structure.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
