Abstract
The invention discloses a pin remover, which relates to a special tool for removing positioning pins from workpieces. The pin remover comprises a supporting plate with a bracket, a sleeve, a core rod and a rotating handle, wherein the sleeve is connected with the supporting plate through threads, the rotating handle is arranged above the sleeve, and when the rotating handle is rotated, the sleeve can move up and down relative to the supporting plate; the upper end of the core rod is provided with a boss, the rod body of the core rod is arranged in the sleeve with a clearance in between, a plane bearing is arranged between the boss of the core rod and the upper port of the sleeve, and when the sleeve rotates, the core rode stays still; and the lower end of the core rod is provided with a threaded head to be connected with a central threaded hole of a pin. The pin remover provided by the invention can apply a large and uniform removing force.
Description
Technical field
The present invention relates to a kind of specific purpose tool of pulling out alignment pin on the workpiece.
Background technology
What pin generally adopted on the mould now is that jump bit collision method is pulled pin; This method is pulled pin because of being to adopt ballistic method, and effort can shake the pain of going smoothly, and the efficient of pulling pin is not high.Application number is 99247049.8, and name is called the patented technology of pin releaser, discloses a kind of pin instrument that moves back that is applicable to split pin, round pin, and it adopts lever principle, utilizes manpower to pull out pin.But this technical scheme to pull out power little, be difficult to adapt to big specification or connect tighter alignment pin, in addition, this technical scheme is owing to be that manpower is pulled out, and may occur the situation that jumps and spatter when moving back pin, dynamics is difficult to control.
Summary of the invention
The present invention is directed to above problem, provide a kind of power of pulling out big, and uniform pin removal.
Technical scheme of the present invention is: it comprises gripper shoe, sleeve, plug and the swing handle that has support; Described sleeve links to each other by screw thread with gripper shoe, and described swing handle is arranged on the top of sleeve, and when the turn swing handle, described sleeve is with respect to the upper and lower motion of gripper shoe; The upper end of described plug is provided with step circle, and the barred body of plug is arranged in the sleeve, has the gap between the two, is provided with plane bearing between the step circle of described plug and sleeve upper port, and when sleeve rotated, described plug did not rotate; The lower end of plug is provided with the spiral shell head that is used for connecting pin subcenter screw.
It also comprises spiral shell head quick-acting connector, and described spiral shell head is a screw; The bottom of described plug is provided with thread segment, and described quick-acting connector is tubular, and nozzle is provided with the internal thread that is used to connect described thread segment, the mesopore at the bottom of tube is provided with the spiral shell head part that can make screw the end and stretches out tin.
The present invention utilizes the screw drive sleeve to move both vertically, and sleeve is in the process of motion vertically upward, and the upper surface drives the step circle at plug top, and then drives plug and move upward, thereby the pin that will be connected in the plug bottom is extracted from workpiece.For preventing that sleeve when rotation from driving plug and rotating together, leave certain clearance between circle in plug and the sleeve, be provided with plane bearing between plug top stage circle and the sleeve, drive the plug rotation with overcome friction.In addition, for preventing spiral shell head wearing and tearing in plug bottom in the long-term work, the present invention also provides another solution, can utilize quick-acting connector to connect plain screw and realize the operation of pulling pin.

The specific embodiment
The present invention is as shown in Figure 1: it comprises gripper shoe 9, sleeve 2, plug 3 and the swing handle 10 that has support 1; Described sleeve 2 and gripper shoe 9 link to each other by screw thread, and described swing handle 10 is arranged on the top of sleeve 2, and when turn swing handle 10, described sleeve 2 is with respect to gripper shoe 9 upper and lower motions; The upper end of described plug 3 is provided with step circle 12, and the barred body of plug 3 is arranged in the sleeve 2, has the gap between the two, is provided with plane bearing 11 between the step circle 12 of described plug 3 and sleeve 2 upper port, and when sleeve 2 rotated, described plug 3 did not rotate; The lower end of plug 3 is provided with and is used for connecting " plant and establish " in the spiral shell head 4 of workpiece 6 pins 5 center screws.
Another embodiment of the present invention is as shown in Figure 2: it also comprises spiral shell head quick-acting connector 7, and described spiral shell head 4 is a screw 40; The bottom of described plug 3 is provided with thread segment 8, and described quick-acting connector 7 is tubular, and nozzle is provided with the internal thread that is used to connect described thread segment 8, the mesopore at the bottom of tube is provided with the spiral shell head part that can make screw 40 end and stretches out tin.
Job order of the present invention:
1, needs are pulled out to such an extent that the inside/outside hex screw 40 usefulness quick-acting connectors 7 of pin 5 specifications are connected on the thread segment 8 of lower end of plug 3;
2, rotation plug 3 screws in the screw 40 of lower end in the hole of pulling pin of pins 5;
3, with swing handle 10 turnbarrels 2, sleeve 2 is upwards risen, drive plug 3 and move upward, finish the action of pulling pin.
