Description
Technical field
The invention belongs to printed circuit board (PCB) manufacture auxiliary equipment field, be specifically related to a kind of for the instrument by the bearing removal in heat pressing wheel holder.
Background technology
Heat pressing wheel is requisite parts in PCB hot pressing processing procedure, and the rotating shaft two ends of heat pressing wheel are fixed in bearing, and bearing is fixed on board by being fixed in pinch roller holder again.When removing and installing heat pressing wheel, need the bearing that will be positioned at pinch roller holder to remove, the dismounting mode of traditional bearing supports bearing to beat pinch roller holder, bearing got loose in pinch roller holder drop out with beaing the mode supported of cooperation.The mode of this dismounting bearing not only compares to waste time and energy, and easily causes pinch roller holder to wear and tear especially, has press mold gauffer when doing plate, also affect the service life of pinch roller holder.
Summary of the invention
In order to solve the problem; the invention provides a kind of heat pressing wheel holder bearing extractor; this heat pressing wheel holder bearing extractor can save the time of removing and installing, and more makes pinch roller holder service life extend, thus cost-saving and reduce the shutdown loss that press mold gauffer causes.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of heat pressing wheel holder bearing extractor, be made up of thrust screw rod part and abutting hook part two parts, described thrust screw rod part is made up of screw rod and positioning pedestal, described positioning pedestal can be connected and fixed on the rear end of pinch roller holder, described positioning pedestal center has screw, described screw flight is connected in screw, described abutting hook part is by abutting bar, fixed bar, spring and shank are formed, described abutting rod rear end can be through in bearing and to abut against with described screw rod, described fixed bar is fixed on and abuts bar first half and with to abut bar vertical, the two ends of fixed bar are positioned at the both sides abutting bar, the two ends of fixed bar have limit stops, fixed bar is positioned at the part abutting bar both sides and is all coated with a spring and a shank, the inner of each spring abuts bar and outer end abuts shank, shank is between limit stops and spring, the rear end of shank has the hook that can hook bearing inner wall groove.
The present invention in order to the further technical scheme solving its technical problem and adopt is:
Say further, the axis hole place, rear end of described pinch roller holder is fixed with a circle backward for the retainer ring with hot pressing wheel shaft lock, described positioning pedestal is by locking annulus and screw disc is formed, described locking annulus extends formation forward from the edge of described screw disc, described locking annulus can be placed on described retainer ring periphery and lock with retainer ring, and the center of described screw disc is screw.
Say further, described screw front end is pointed for boring.
The invention has the beneficial effects as follows: pinch roller holder bearing extractor of the present invention is made up of thrust screw rod part and abutting hook part two parts, during use, the positioning pedestal of thrust screw rod part is locked in pinch roller holder rear end, two shanks abutting hook part are unclamped shank to pinching and being inserted into after in bearing, the hook of shank is made to hook bearing inner wall groove, then the screw rod of rotary thrust screw rod part, screw rod is made to support the abutting bar abutting hook part, the thrust forward produced by screw rod is promoted to abut bar and travels forward and drive the bearing by shank hooks to move forward, thus bearing is split out in pinch roller holder.This heat pressing wheel holder bearing extractor can not save the time of removing and installing, pinch roller holder uniform force when more making dismounting, easy to wear, and pinch roller holder extends service life, thus cost-saving and reduce the shutdown loss that press mold gauffer causes.

Fig. 2 is pinch roller holder bearing extractor using state schematic diagram of the present invention.
Detailed description of the invention
Below by way of specific instantiation, the specific embodiment of the present invention is described, those skilled in the art can understand advantage of the present invention and effect easily by content disclosed in the present specification.The present invention also can be implemented in further, different ways, that is, not departing under disclosed category, can give different modifications and change.
Embodiment: a kind of heat pressing wheel holder bearing extractor, as illustrated in fig. 1 and 2, be made up of thrust screw rod part 1 and abutting hook part 2 two parts, described thrust screw rod part is made up of screw rod 11 and positioning pedestal 12, described positioning pedestal can be connected and fixed on the rear end of pinch roller holder 3, described positioning pedestal center has screw, described screw flight is connected in screw, described abutting hook part is by abutting bar 21, fixed bar 22, spring 23 and shank 24 are formed, described abutting rod rear end can be through in bearing and to abut against with described screw rod, described fixed bar is fixed on and abuts bar first half and with to abut bar vertical, the two ends of fixed bar are positioned at the both sides abutting bar, the two ends of fixed bar have limit stops, fixed bar is positioned at the part abutting bar both sides and is all coated with a spring and a shank, the inner of each spring abuts bar and outer end abuts shank, shank is between limit stops and spring, the rear end of shank has the hook 241 that can hook bearing inner wall groove.
The axis hole place, rear end of described pinch roller holder is fixed with a circle backward for the retainer ring 31 with hot pressing wheel shaft lock, described positioning pedestal is by locking annulus 121 and screw disc 122 is formed, described locking annulus extends formation forward from the edge of described screw disc, described locking annulus can be placed on described retainer ring periphery and lock with retainer ring, and the center of described screw disc is screw.
