Description
Technical field
This utility model belongs to frock technical field, more particularly to one kind drive automatically top.
Background technology
At present during the hard car of spline machining bearing guard, centre bore is lived using Double Tops pinnacle and is positioned, each part processing
Front need to install a heart carrier for the driving of part.Have the disadvantage that：1st, low production efficiency, needs before processing every time
One heart carrier is installed, will also be removed after machining；2nd, labor intensity of operating staff is big, increased assembling and disassembling heart carrier for bolt
The step of head；3rd, the equipment such as robot cannot realize the installation of movement chuck, so automated production cannot be realized.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of production efficiency height, work
Automatically the driving of low intensity is top.
The purpose of this utility model drives top, spring, driving by following technical solution completing by spindle end
Axle, the drive block of actuating sleeve composition, the drive block are located at the big end of the step endoporus that is provided with of splined shaft；Described spindle end
Drive top one end to be cased with actuating sleeve and in gap cooperation, the actuating sleeve and spindle end drive top between spring is installed；Institute
The actuating sleeve that states is provided with a circle conical tooth, annulus cylinder by circular cone and annulus cylinder integrated die-casting molding, wherein circular cone
Radial surface be provided with two and be symmetric strip through-hole.
Preferably, the conical tooth of described circular cone is in spline machining, in the step being provided with splined shaft
It is in interlocking pattern between the step surface wedge angle in hole.
Preferably, the strip through-hole of described annulus cylinder drives the through hole is provided with by top radial direction to align with spindle end
And insert drive shaft.
The beneficial effects of the utility model are：Improve class to produce, through actual measurement, production efficiency improves 60%, and reduce having
Serve fatigue resistance, in three-shift system workshop, improved efficiency is obvious.

Specific embodiment
Detailed introduction is done to this utility model below in conjunction with accompanying drawing：As shown in accompanying drawing 1 to 3, this utility model is by leading
Shaft end drives top 1, spring 2, drive shaft 3, the drive block of the composition of actuating sleeve 4, the drive block to be located at the platform is provided with by splined shaft 5
At 51 big end of stepped endoporus；Described spindle end drives top 1 one end to be cased with actuating sleeve 4 and coordinate in gap, the actuating sleeve 4
Drive with spindle end, between top 1, spring 2 is installed；Described actuating sleeve 4 by circular cone 41 and 42 integrated die-casting of annulus cylinder into
Type, wherein circular cone 41 are provided with a circle conical tooth 43, and the radial surface of annulus cylinder 42 is provided with two and is symmetric bar
Shape through hole 44.
The conical tooth 43 of described circular cone 41 when splined shaft 5 is processed, the step endoporus 51 being provided with splined shaft 5
Step surface wedge angle between be in interlocking pattern.
The strip through-hole 44 of described annulus cylinder 42 drives top 1 through hole 11 being radially provided with to align simultaneously with spindle end
Insertion drive shaft 3.
The characteristics of using 5 structure of splined shaft, design one and drive splined shaft 5 to rotate with the actuating sleeve 4 that inner surface drives, no
Need each part, when processing, heart carrier is installed.
Actuating sleeve 4 is coordinated using larger gap with main shaft drives top 1, prevents 51 surface of endoporus different from centre bore 52
The side force produced during the heart, affects the positioning precision of centre bore 52.The endoporus 51 is contacted with actuating sleeve 4, centre bore 52 with main
Shaft end drives top 1 center point to contact.
The driving of actuating sleeve 4 carries out circumferential driving by the drive shaft 3 being fixed in main shaft drives top 1.
Actuating sleeve 4 can axially stretch with drive shaft 3, and splined shaft 5 is pushed up top to main shaft drives by tailstock live centre 6
1, and top with main shaft drives 1 by 5 axial restraint of splined shaft, actuating sleeve 4 under the spring-force driven dual of spring 2, the cone of actuating sleeve 1
43 surface of shape tooth forms interlocking pattern with the step surface wedge angle of axle endoporus 51, produces the frictional force more than cutting force, drives part
Rotation.
Operation principle of the present utility model is：Using the pressure on top surface of the tailstock live centre 6 of lathe, and main shaft drives are top
12 elastic force of spring, makes the conical tooth 43 on actuating sleeve 4 be engaged with wedge angle, forms driving force, drives the rotation of 5 part of splined shaft,
Complete Vehicle Processing.
This utility model is not limited to above-mentioned embodiment, no matter constitute in its shape or material making any change, all
It is using structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality
Within type protection domain.
