Description
Technical field
The present invention relates to the taper roll bearing technical field, relate in particular to a kind of improvement of taper roll bearing retainer hole punched device.
Background technology
At present; Traditional taper roll bearing retainer hole punched device is to utilize the mode of manually rotation pulling shaft, pressure cap locking that retainer is positioned clamping; Its operation principle is a (see figure 4): manual rotary handle 10; After driving pulling shaft 4, compressing retainer 2, drive the mould friction with press equipment and rotate and carry out retainer window five equilibrium with pulling shaft wire drawing tension pressure cap 1.Find in the production that there is following problem in this retainer hole punched device: the one, clamping power is little, causes branch errors such as retainer window big easily, the punching low precision; The 2nd, operator's labour intensity is big, and troublesome poeration, and production efficiency is low.
Summary of the invention
The objective of the invention is to overcome the shortcoming of traditional round taper roller bearing retainer punching die,
The improved taper roll bearing retainer hole punched device that a kind of punching precision is high, simple to operate, production efficiency is high is provided.
The objective of the invention is to realize through following technical scheme, this improved taper roll bearing retainer hole punched device comprise pulling shaft, pulling shaft cover, etc. minute wheel, spring chuck, spring, pull head, slip cap, master jaw, pulling dish, the middle part of said pulling shaft is provided with the pulling shaft cover; One end of said pulling shaft such as is provided with at minute wheel; The front end of said minute wheel such as grade is a bell mouth shape, and the other end of said minute wheel such as grade extends into sleeve-like and is connected with the pulling shaft cover, and said the grade in the minute wheel is provided with spring chuck; Be provided with spring that is placed on the pulling shaft and the pull head that links to each other with the pulling shaft top in the said spring chuck; The other end of said pulling shaft is fixed with the pulling dish, and a side of said pulling dish is provided with inclined-plane, a border, and an end of said pulling shaft cover is fixedly connected a master jaw; Said master jaw is provided with claw; Pulling shaft on said next-door neighbour's master jaw puts and is provided with the slip cap that can slide along pulling shaft cover, and an end of said slip cap also is provided with a taper seat, the centre of said claw and master jaw flexible connection; The inclined-plane that a side is coiled in one end and the pulling of claw contacts, and the other end of claw contacts with the taper seat of slip cap.
Said master jaw one border is first-class to be arranged with three claws.
A said end that waits minute wheel to prolong into sleeve-like is respectively equipped with locking nut and brake rocker arm.
During work, with slip cap is moved right, be movably connected on the master jaw because of in the middle part of the claw by lever power works; Taper seat on the slip cap lifts an end of claw gradually, and the other end of claw presses down gradually and promotes the pulling dish to the right, and through pulling shaft pulling pull head; Spring compression this moment, the spring chuck tensioner holds the retainer endoporus, because of there is certain cone angle spring chuck and retainer contact position; Evidence, the cone angle of spring chuck and retainer contact position is better with 10 °, can make the retainer nature near equal portions wheel end face during tensioner; Play the role of positioning, simultaneously also can produce less cone angle during the spring chuck tensioner, better with 0 ° of 30 ' cone angle; Play the positioning and locking effect with minute wheel such as main body, thereby accomplish the action that is installed, drive the mould friction with press equipment then and rotate and carry out retainer window five equilibrium.After operation was accomplished, with making slip cap to left movement, claw was lax through lever power works, because spring action makes pull head to left movement, spring chuck is lax, takes off retainer, and this work is accomplished.
Beneficial effect of the present invention:
1, improved clamping workpiece power, dwindled branch errors such as retainer window, the punching precision is high; Make branch quality such as retainer window guaranteed, reduced percent defective.
2, improved production efficiency, retainer single-piece clamping time decreased 2～3S; The raising of clamping power provides guarantee to perforating press, and perforating press speed-raising back production efficiency has improved about 30% before improving.
3, reduce working strength of workers.

The specific embodiment
Among the figure: 1, pulling shaft 2, pulling shaft cover 3, etc. minute wheel 4, spring chuck 5, spring 6, pull head 7, slip cap 8, master jaw 9, pulling dish 10, inclined-plane 11, claw 12, taper seat 13, locking nut 14, brake rocker arm 15, retainer
As shown in Figure 1, this improved taper roll bearing retainer hole punched device comprise pulling shaft 1, pulling shaft cover 2, etc. minute wheel 3, spring chuck 4, spring 5, pull head 6, slip cap 7, master jaw 8, pulling dish 9, the middle part of pulling shaft 1 is provided with pulling shaft cover 2; One end of pulling shaft 1 such as is provided with at minute wheel 3, and the front end that waits minute wheel 3 is a bell mouth shape, waits the other end of minute wheel 3 to extend into sleeve-like and is connected with pulling shaft cover 2; An end that prolongs into sleeve-like Deng minute wheel 3 is respectively equipped with locking nut 13 and brake rocker arm 14; Deng being provided with spring chuck 4 in the minute wheel 3, being provided with in the spring chuck 4 spring 5 that is placed on the pulling shaft 1 and the pull head 6 that links to each other with the pulling shaft top, the other end of pulling shaft 1 is fixed with pulling dish 9; One side of pulling dish 9 is provided with inclined-plane, a border 10; One end of pulling shaft cover 2 is fixedly connected a master jaw 8, and master jaw 8 one borders are first-class to be arranged with three claws 11, and the pulling shaft cover 2 on next-door neighbour's master jaw 8 is provided with the slip cap 7 that can slide along the pulling shaft cover; One end of slip cap 7 also is provided with a taper seat 12; The middle part of claw 11 and master jaw 8 flexibly connect, and the inclined-plane 10 that 9 one sides are coiled in an end and the pulling of claw 11 contacts, and the other end of claw 11 contacts with the taper seat 12 of slip cap 7.
During work, by lever power works with slip cap 7 is moved right, because of claw 11 middle parts are movably connected on the master jaw 8; Taper seat 12 on the slip cap 7 lifts an end of claw 11 gradually, and the other end of claw 11 presses down gradually and promotes pulling dish 9 to the right, and through pulling shaft 1 pulling pull head 6; Spring 5 compressions this moment, spring chuck 4 tensioners hold retainer 15 endoporus, because of there are 10 ° of cone angles spring chuck 4 and retainer 15 contact positions; Can make retainer 15 nature near equal portions wheel end face during tensioner, play the role of positioning, can produce 0 ° of 30 ' cone angle during spring chuck 4 tensioners simultaneously; Therefore the contact position has one 0 ° of 30 ' cone angles simultaneously; Play the positioning and locking effect with minute wheel 3 such as main body, thereby accomplish the action that is installed, drive the mould friction with press equipment then and rotate and carry out retainer 15 window five equilibriums.After operation was accomplished, with making slip cap 7 to left movement, claw 11 was lax through lever power works, because spring 5 effects make pull head 6 to left movement, spring chuck 4 is lax, takes off retainer 15, and this work is accomplished.
