Description
Technical field
The present invention relates to a kind of Workpiece machining apparatus technical field, more particularly to a kind of frock for work pieces process to press from both sides
Tool.
Background technology
At present, the processing of the gear hobbing of most of factories pair and gear, shaving, gear honing and roll flute at present, generally by machine
The cooperations of two thimbles and main shaft of bed is realized.In processing, make main shaft being articulated on lathe, one of thimble
Be connected to an end of main shaft, by gear set to be processed on main shaft, then worn on main shaft connect an axle sleeve and
Pressure ring, and locked pressure ring and axle sleeve by nut, so as to fixation of the time gear on main shaft, then make another on lathe
Thimble withstands another end of main shaft, and hereafter live spindle, is processed.But above-mentioned processing tool, in Gear Processing, often
Secondary clamping and dismounting gear are required for disassembling nut completely, so that processing efficiency reduces；And in process, gear is simultaneously
Do not possess certain pretightning force, easily occur stuck situation in process.
The content of the invention
For overcome the deficiencies in the prior art, it is an object of the invention to a kind of frock clamp for work pieces process, its
Can workpiece convenient disassembly, and certain pretightning force can be provided
The purpose of the present invention adopts the following technical scheme that realization：
A kind of frock clamp for work pieces process, including main shaft, gland and elastomeric element, the outerface of spindle are provided with limit
Position portion, gland is removably movable to be set in the outerface of spindle, gland close to the end of limiting section and limiting section it
Between interval formed clamping gap；The elastomeric element, which is used to provide, makes gland towards the elastic stress close to limiting section motion.
Further, the outer surface of the main shaft, which radially inside contracts, is formed as First terrace, and the First terrace is formed
The limiting section.
Further, the elastomeric element is spring, and one end of the spring, which is set in the outerface of spindle and worn, to be connect
In to the gland；The other end of spring is used for by external force top pressure.
Further, the gland outer surface is provided with screwed hole, and screwed hole is extended radially to inside gland along gland；Screw thread
Bolt is bolted with hole, the afterbody of the bolt is connected to the elastic end so that the end of spring is fixed with gland.
Further, the second step face extended radially inwardly along gland, the second step face are provided with inside the gland
For being connected to the end of spring.
Compared with prior art, the beneficial effects of the present invention are：Its workpiece can clamping be spaced between gland and limiting section
In the clamping gap of formation, and clamped by the elastic stress of elastomeric element offer, the length of adjustable spring is pressed to adjust
The size of clamp force, makes the clamping of workpiece have certain pretightning force, and process is more smooth, and in clamping or dismounting, only
Gland is set to exit main shaft, it is not necessary to locking nut manually to be twisted again, so as to the operating efficiency improved.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：10th, main shaft；11st, First terrace；20th, gland；21st, second step face；22nd, bolt；30th, spring；40、
Gear.
Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
A kind of frock clamp for work pieces process as shown in Figure 1, including main shaft 10, gland 20 and elastomeric element, tool
Body is provided with limiting section in the outer surface of main shaft 10, and gland 20 is removably movable to be set in the outer surface of main shaft 10, the pressure
Set 20 can be along the axial movement of main shaft 10.In this way, it can be spaced to be formed between the end of limiting section and limiting section in gland 20
Clamp gap.In addition, elastomeric element is used for elastic stress, gland 20 can be towards close to limiting section in the presence of the elastic stress
Motion.
On the basis of said structure, using the present invention the frock clamp for work pieces process when, using workpieces processing as tooth
Exemplified by wheel 40, one end of main shaft 10 can be articulated on lathe and by the top top pressure on lathe, and gear 40 to be processed can be worn
Enter on main shaft 10, gear 40 can be abutted to the limiting section of main shaft 10, gland 20 is penetrated main shaft 10 and in elastic stress
Moved under effect towards limiting section, gear 40 can be pressed in clamping gap, and other on lathe top is connected to bullet
Property part end, the length of so adjustable spring 30 adjusts the size of thrust, make workpiece clamping have it is certain
Pretightning force, process is more smooth, and in clamping or dismounting, as long as making gland 20 exit main shaft 10, it is not necessary to again
Manually stubborn locking nut, so as to the operating efficiency improved.
Further, in the present embodiment, the outer surface of main shaft 10, which radially inside contracts, is formed as First terrace 11, and this first
Step surface 11 forms limiting section, by First terrace 11 and the end abutment of work gear 40 to be added, realizes positioning, mounting structure
It is relatively stable.Certainly, the limiting section can also be formed by the boss for being convexly equipped in the outer surface of main shaft 10.
Further, above-mentioned elastomeric element is spring 30, one end of spring 30 is set in the outer surface of main shaft 10 and is worn
It is connected in gland 20, while the other end of spring 30 is used for by external force top pressure, specifically can be by top top pressure on lathe.In this way, can
The stretching motion of spring 30 is set to be limited in the axial direction of main shaft 10, the elastic stress provided is more stable.In addition, above-mentioned elasticity
The part that other flexible deformation such as block rubber also can be selected in part is formed.And the end of elastomeric element may also be direct fixation
On lathe, it equally can also realize that the clamping of workpiece compresses.
Further, screwed hole can be provided with the outer surface of gland 20, the screwed hole is extended radially to gland along gland 20
Inside 20.Bolt 22 is specifically bolted with screwed hole, the afterbody of the bolt 22 can be connected to the end of elasticity so that spring 30
End fixed with gland 20, in this way, clamping or dismounting workpiece when, spring 30 can be synchronous with the motion of gland 20, just
It is more convenient with dismounting in simultaneously operating, clamping.
Further, second step face 21 can be provided with inside gland 20, the second step face 21 can be along gland 20 radially
Extend internally, when spring 30 is stretched into gland 20, the second step face 21 can be connected to the end of spring 30, be easy to gland 20
By the top pressure of spring 30, it is more uniformly stressed.Certainly, in the case of no second step face 21, spring 30 can direct top pressure
End face of the gland 20 away from limiting section, it equally can also realize above-mentioned compression effect.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed scope.
