Description

A kind of general gear-hobbing clamp
Technical field
The utility model belongs to the gear hobbing process field of fixtures in mechanical processing, particularly adapts to plurality of specifications size endoporus Position gear hobbing product, and in particular to a kind of general gear-hobbing clamp.
Background technology
At present, the fixture of engineering goods gear hobbing process is all that hole axle is taken to coordinate unitary design(Unitary design structure Such as Fig. 1), the locking to workpiece 7 is realized by the extruding pressing plate 8 of nut 9, it is this to design in use principle and have no problem.But This structure gear-hobbing clamp design is exactly to have uniqueness for product, i.e. the same size of identical product can only correspond to one A gear-hobbing clamp, since gear-hobbing clamp structure is larger, material deterioration inside is more, once change in design fixture is integrally scrapped, so fixture Adaptability is poor.As market competition, the target for maximizing and being only enterprise and constantly pursuing is generated profit with minimum cost.
Utility model content
To solve the above problems, the purpose of this utility model is to provide a kind of general gear-hobbing clamp, it is simple in structure, add Work precision is high, and error is smaller, strong applicability.
In order to achieve the above object, the technical solution adopted in the utility model is:A kind of general gear-hobbing clamp, including upper end band The split type clamp body of screw thread;The split type clamp body lower end is solid, and upper end is the tapered sleeve of inner hollow;On the screw thread Nut is set with, the nut is internally provided with protruding portion;The protrusion is mobilizable to be moved in tapered sleeve hollow position;Described Vacancy is provided with the spindle nose with taper in tapered sleeve, offers the slot of multiple perforations on the conical surface of the tapered sleeve, in the slot It is provided with mandril;Transition sleeve is set with outside the tapered sleeve, mandril is resisted against on the conical surface of transition sleeve inner wall and spindle nose;The axis Head lower end is provided with compressed spring, and the compressed spring is fixed on split type clamp body.
Further, the tapered sleeve is with 3 ° of male cone (strobilus masculinus), and the transition sleeve outer wall is cylindrical surface, and inner wall is with 3 ° Inner conical surface, transition sleeve and tapered sleeve clearance fit, transition sleeve external cylindrical surface and inner hole of workpiece cylindrical surface clearance fit.
Further, it is provided with pressing plate at the tapered sleeve outer rim.
Further, the transition sleeve is elasticity transition set.
The beneficial effects of the utility model:The utility model device design principle is simple, easy to use, and error is minimum, especially It is requiring processing accessory size precision to be promoted the use of compared with senior middle school, such as turning, cylindricalo grinding processing shaft hole matching tooling.
1. during using the utility model fixture converted products, product is bigger, and effect is more apparent;This separate structure is not only made It is relatively easy to make technique, and the manufacturing cycle is short, saves material, for integrally-built gear hobbing process fixture, this reality With novel clamp in production convenient for management.
2. mating surface makes 3 ° of conical surfaces by original cylindrical surface, then adds 3 ° of conical surface transition sets.3 ° of conical surface transitions cover inner cone With 3 ° of conical surfaces of tapered sleeve, " 0 " clearance fit is realized by being adjacent to;The endoporus of 3 ° of conical surface transition set external cylindrical surfaces and gear hobbing process workpiece Cylindrical surface, which is realized, to be fitted close.
3. tapered sleeve is internally provided with the spindle nose with taper, by the displacement of spindle nose, mandril is driven to squeeze elasticity transition set, into One step increases the fitness of transition sleeve and workpiece, to reduce mismachining tolerance.

Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, below in conjunction with the accompanying drawings to this reality Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the scope of protection of the utility model There is any restriction effect.
As Figure 2-Figure 5, the concrete structure of the utility model is:A kind of general gear-hobbing clamp, it is threaded including upper end 101 split type clamp body 1;1 lower end of split type clamp body is solid, and upper end is the tapered sleeve 10 of inner hollow;The spiral shell Nut 2 is set on line 101, the nut 2 is internally provided with protruding portion 21;The protruding portion 21 is mobilizable in tapered sleeve 10 Empty position moves;Vacancy is provided with the spindle nose 3 with taper in the tapered sleeve 10, is offered on the conical surface of the tapered sleeve 10 multiple The slot 102 of perforation is provided with mandril 4 in the slot 102;Be set with transition sleeve 5 outside the tapered sleeve 10, mandril 4 against On the conical surface of 5 inner wall of transition sleeve and spindle nose 3;3 lower end of spindle nose is provided with compressed spring 6, and the compressed spring 6 is fixed on On split type clamp body 1.
Preferably, the tapered sleeve 10 is with 3 ° of male cone (strobilus masculinus), and 5 outer wall of transition sleeve is cylindrical surface, inner wall be with 3 ° of inner conical surface, transition sleeve 5 and 10 clearance fit of tapered sleeve, 5 external cylindrical surface of transition sleeve and 7 endoporus cylindrical surface clearance fit of workpiece.
Preferably, it is provided with pressing plate 8 at 10 outer rim of tapered sleeve.
Preferably, the transition sleeve 5 is elasticity transition set.
Clamp principle:Transition sleeve 5 is selected in advance, makes the internal diameter of transition sleeve 5 and the diameter that tapered sleeve 10 forms and workpiece 7 Size is closest, and transition sleeve 5 is set on tapered sleeve 10, further workpiece 7 is assemblied on split type clamp body 1, Ran Houyi Secondary suit pressing plate 8 and nut 2, then screw up nut 2, at this time 8 workpiece pressing 7 of pressing plate, and protruding portion 21 squeezes spindle nose 3, passes through axis First 3 displacement drives mandril 4 to squeeze elastic transition sleeve 5, so as to which workpiece be made firmly to be assemblied in split type clamp body 1 On, it has solved during gear hobbing process, due to gap error existing between workpiece 7 and clamp body, has caused finally to process The problem of workpiece come can not assemble;Facts proved that 3 ° of conical surface transitions of processing cover 5 manufacture materials for entire clamp body Save 75~90%.
