Description
Technical field
The present invention relates to machining equipment, especially for the waterproof sealing in rotating shaft gap, specifically a kind of tool
There is the multistation trepan of coolant anti-leakage function.
Background technology
Multistation trepan is mainly used in the accurate set hole machined of the crisp and hard materials such as magnetic material, semi-conducting material, glass.
It is main in the multistation trepan of prior art, structure to include being used to clamp workpiece to be added and make the clamping dress of workpiece rotation to be added
Put, some cutter tips, and the drive mechanism that driving cutter tip is moved along cutting direction, in order to prevent complete machine from running
Heated up in journey too fast, coolant water pipe is connected with the rear end of cutter tip, coolant water pipe connection water pump during operation, passes through
Water pump conveying coolant reaches cooling-down effect.But in use, it is found that clamping device sealing effectiveness is also less desirable,
Coolant enters inside clamping device, and influence is caused on the service life of clamping device internal bearings.Such as Patent No.
201210159020.4 patent names are the patent of " multistation trepan ", and sealing waterproof is carried out using labyrinth type water-proof plate 5, though
It can play certain sealed waterproof effect, but but effect is not good, and major defect includes following 5：
It is to be fixedly connected with relation successively that 1. the first annulus 51, the 3rd annulus 53, the second annulus 52 are with snap ring 54, processing and assembling
Difficulty is big, and junction is easily broken off and seeped water；
2. labyrinth type water-proof plate 5 is " abutting against on step surface 11 ", " being closely fastened in boss 12 " this means water-proof plate 5 is gone back
It is that can be moved axially on clamping device 1, and the handing-over gap for the support and clamping device 1 for installing clamping device 1 is still deposited
In gap, easily infiltration；
" 3. snap ring 54 is closely fastened in boss 12 ", two can produce when having the member in tight engaging of rotary speed difference because rubbing
Raw substantial amounts of heat and the rotary resistance for increasing clamping device 1.It can be squeezed after snap ring 54 is due to the expansion of heated or stress deformation
Belling platform 12, on the one hand produces friction with boss 12, accelerates the abrasion of snap ring 54, then cause sealing property to weaken；It is another
Aspect friction exacerbates the rotary resistance of clamping device 1 again.
4. " section of labyrinth type water-proof plate 5 is in not completely enclosed rectangle " first annulus 51 is mentioned in specification from fixing point
Second annulus 52 and snap ring 54 farther out, easily raise the first annulus 51 according to lever principle coolant, then gradually penetrate into card
The position of ring 54.
5. boss 12 is the part for belonging to clamping device 1, it is that process and assemble is formed together with clamping device, necessarily increases
Difficulty of processing and reduction precision.Need to change whole clamping device when after the abrasion of boss 12.
The content of the invention

Provided with the horizontal recessed 61b matched with horizontal convex 62d between 61 end faces.Horizontal convex 62d enhances the average thickness of sub anti-oil cap 62, and
The benefit that horizontal convex 62d is caught in horizontal recessed 61b has two：1. sub anti-oil cap 62 adds horizontal convex 62d as fulcrum so that sub anti-oil cap 62
Edge be not easy to be started by coolant.2. the contact area of female anti-oil cap 61 and sub anti-oil cap 62 is added, sealing property is more
Good, horizontal convex 62d axial rotations in horizontal recessed 61b ensure that the cooperation of sub anti-oil cap 62 and female anti-oil cap 61 is more firm.
In embodiment, as shown in Figure 3 and Figure 4, it is grease proofing located at son that female anti-edge of oil cap 61 is extended with lining eaves 61c, lining eaves 61c
Between lid 62 and main spindle box 11.Lining eaves 61c can prevent sub anti-oil cap 62 from producing direct friction with main spindle box 11.
In embodiment, as shown in Figure 3 and Figure 4, female anti-periphery of oil cap 61 is provided with mother water jacket 61d, female water jacket 61d close to lining eaves
61c, interior lining ring 62b peripheries are provided with the sub- water jacket 62e for being used for burying sealing ring 63.It can be selected in son for higher waterproof effect
Water jacket 62e sets up sealing ring 63.Female water jacket 61d is also avoided that female anti-oil cap 61 by the sub anti-side of oil cap 62 as stress relief grooves
Open on edge top.
In embodiment, as shown in Figure 3 and Figure 4, female anti-edge of oil cap 61 is provided with the spiral shell for being used for inserting screws into main spindle box 11
Nail 61a, sub anti-oil cap 62 is provided with the thread segment 62a for being used for being threaded in workpiece rotating shaft 1；Sub- water jacket 62e is provided with sealing
Circle 63.
In embodiment, thread segment 62a rotation direction is oppositely oriented with workpiece rotating shaft 1.It can be driven when workpiece rotating shaft 1 rotates
The anti-oil cap 62 of son is drawn close to female anti-oil cap 61, enhances sealing water resistance.
In embodiment, as depicted in figs. 1 and 2, the lower section of main spindle box 11 is fixed with the workbench 71 being obliquely installed, workbench 71
The bottom of inclined plane is provided with spill port 72, and the surrounding of workbench 71 is equipped with anti-food tray 73；Main spindle box 11 is formed in one structure.Work
Make platform 71 to recycle with the waste recovery for facilitating coolant and processing to produce toward top rake by certain angle.
In embodiment, as depicted in figs. 1 and 2, the top of workbench 71 is provided with the slide plate 3 for fixing cutter chuck 2, slide plate
3 upper end is fitted with grease proofing coaster 81；The both sides of workpiece rotating shaft 1 are respectively equipped with the backplate for being connected to grease proofing coaster 81.Grease proofing coaster
81 are installed in the upper end of slide plate 3, and workman independently can horizontally slip slide plate 3, and to facilitate loading and unloading, grease proofing coaster 81 is close to main
Respectively there is the backplate being processed into by iron plate before and after the direction of axle box 11, backplate is welded to connect in the side of the direction of advance of grease proofing coaster 81
Edge position.Grease proofing coaster 81 and backplate effectively can prevent coolant from splashing in equipment work.
Technology disclosed in above example is applicable not only to trepan, apply also for puncher, edge polisher etc. have turn
The equipment of axle construction.
Highly preferred embodiment of the present invention has been illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
It can depart from the scope of the present invention.
