The pin shaft of line is pressed.Some workpiece sizes are larger, can not block workpiece using both ends and are pressed into or pulled in, pull out or press
Out.
It is similar with usage mode three, the plane for welding drawing block is adjacent in the part for being equipped with the pin shaft being disassembled
On, and securely weld together, by the pin shaft for needing to be pressed into positive mounting hole, starts hydraulic pump, stretch hydraulic cylinder piston rod
Out, pin shaft is pressed into the mounting hole of part, completes the indentation work of pin shaft.
Usage mode five
As shown in figure 5, being loaded using the embodiment of the present invention to certain guide.
Suitable guide platen 12 is selected according to guide inner diameter size, guide platen 12 is certain thickness disk, disk
Outer diameter one end is big, and one end is small, and inner hole is threaded hole, and diameter dimension and lead screw mandril 7 are identical；By the piston of hydraulic cylinder
Bar stretches out certain distance, if lead screw mandril 7 is screwed out piston rod certain distance apart from deficiency, until guide platen 12 can revolve
Until entering to install on lead screw mandril 7, guide platen 12 is then being pressed against into guide to be mounted, to the mounting hole of positive part, by pin
The internal screw thread for covering platen 12 screws in the external screw thread of lead screw mandril 7, to end face to until putting down.Start hydraulic oil pump, operation handle makes
The piston rod of hydraulic cylinder is retracted into oil cylinder, and guide is pressed into part, to installation site after stop, complete guide pull in
Operation in part.
Usage mode six
As shown in fig. 6, being pressed using the embodiment of the present invention to certain guide.
Suitable guide platen 12 is selected according to guide inner diameter size, guide platen 12 is against the guide to be pressed into, to Zhengan County
After filling hole, start hydraulic oil pump, the piston rod of hydraulic cylinder is stretched out and guide is pressed into part by operation handle, to installation
Stop behind position, completes the operation being pressed into guide in part.
As shown in fig. 7, the usage mode of the embodiment of the present invention is not limited to and above-mentioned six kinds of usage modes, it can be according to not
Pin shaft together, guide installation and removal requirement, carry out adjustment appropriate, convert out more combinations, to meet various
The pin shaft of class and guide remove and install needs.In addition, screw rod adjusting set, pulling pin screw rod 8, guide platen 12, lead screw mandril
7, connecting rod 1, welded sleeve 11, the U-shaped block of aperture adjustment, are equipped with various sizes of multiple groups, can come according to actual needs
