To keep the contents of the present invention more obvious and easy to understand, done further below in conjunction with attached drawing 1- Fig. 7 and specific embodiment
Description.
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
As shown in Figure 1-3, helping flat centralising device in the present embodiment, the V-arrangement positioning device of workpiece is used to support including two
And it is placed in the centralising device between two V-arrangement positioning devices and being arranged on center base 4 and helps leveling device.
By two V-arrangement positioning devices, centralising device and leveling device is helped, triplicity helps flat centralising device at a set of, can be with
It realizes the centering to axle housing part, help flat process requirements.
As shown in Figure 1, V-arrangement positioning device includes pedestal 1, slide plate 2 and V-arrangement bearing 3, slide plate 2 is slided by linear guide
It is arranged on pedestal 1, V-arrangement bearing 3 is fixed on slide plate 2.By pedestal, the slide plate being mounted on the base and it is mounted on slide plate
V-arrangement bearing constitutes the V-arrangement positioning device of single group, and slide plate can move certain stroke on pedestal, to be applicable in different processing pair
As.
As shown in Figures 4 and 5, helping leveling device includes helping 8, two pieces of lifts plate, 11, four guide sleeves 10 of guide rod of support plate 14, four
With four springs 9, four guide sleeves 10 are separately positioned on center base 4 to be inserted into respectively for four guide rods 11, and four guide rods 11 are solid
It is scheduled on the back side for helping lifts plate 8, four springs 9 are respectively fitted on four guide rods 11, and 9 both ends of spring are respectively against 11 end of guide rod
10 end face of face and guide sleeve；Two pieces of support plates 14 are respectively separated on the front for being arranged in and helping lifts plate 8.
As shown in Fig. 4,5,6 and 7, centralising device includes 5, two mandrils 6 of wedge plungers, sleeve body 7 and oil cylinder 13, set
Cross recess is opened up on cylinder ontology 7, defining cross recess is respectively the translot and vertical slot intersected；Sleeve body 7 is from helping lifts plate 8
On centre bore be inserted into and be supported on and help in lifts plate 8, wedge plungers 5 are located in vertical slot, the bottom end floating connection of wedge plungers 5
The piston rod of oil cylinder 13, by 12 floating connection of extension bar, the upper end of extension bar 12 is set for the bottom end of wedge plungers 5 and 13 piston rod of oil cylinder
The fixture block of the bottom end card slot of insertion wedge plungers 5 is set, fixture block upper surface is arc surface, and the depth of card slot is greater than the thickness of fixture block；
13 piston rod of oil cylinder is bolted in the lower end of extension bar 12.Cylinder piston rod front end is equipped with extension bar, and extension bar connection wedge shape is living
Plug, when wedge plungers move upwards, 6 mandrils of promotion stretch out centering, and at this time because of the latching characteristics of tapered ramp, mandril bears processing
Active force after can't retract, this ensure that workpiece will not axial float, to guarantee the machining accuracy of part.Oil cylinder 13
The lower section for helping lifts plate 8 is suspended from by four connecting rods 15；Two mandrils 6 are respectively from the insertion of the both ends of translot and living with wedge shape simultaneously
Plug 5 is slidably connected.Evagination is arranged on the surface that mandril 6 is contacted with wedge plungers 5 " T " type sliding block, in wedge plungers 5 and mandril
On the surfaces of 6 contacts indent be provided with " T " type sliding block matches sliding " T " type sliding slot.Wedge plungers and mandril use T-type
Slot connection, as long as can guarantee that wedge plungers have up and down motion in this way, mandril will necessarily be transported along the T-slot inclined-plane of wedge plungers
It is dynamic, defect that sometimes cannot completely in place when can effectively overcome former mandril using spring reset.Vertical slot inner wall with
Inlay busher 16 between 5 outer surface of wedge plungers, also inlay busher 16 between 6 outer surface of inner wall and mandril of translot.
The present embodiment helps flat centralising device, and centering uses mechanical structure, that is, utilizes the up and down motion of wedge plungers, pushes
Two sides mandril is synchronous to be stretched out or retracts, and realizes the centering of workpiece.It helps and puts down using mechanical structure, pushed away using the floating elastic force of spring
It is dynamic to help moving up and down for lifts plate, guarantee to help the support plate of two sides in lifts plate to be close to workpiece planarization, at this time V of the workpiece along both ends
Shape supports center steering to horizontal attitude, reaches and flat technique is helped to require.
The present embodiment helps the flat centralising device course of work:
After workpiece enters double V-arrangement bearings, lifts plate 8 will be helped to depress using the weight of workpiece, and help the back of lifts plate 8 at this time
Four, face, 9 reaction force of spring will help lifts plate 8 to jack up upwards, because the guiding role being made of guide sleeve 10 and guide rod 11, is helped
Lifts plate 8 can only be whole horizontal move up and down；When the interfix face of work cannot be bonded simultaneously with the support plate 14 of two sides
When, the support plate 14 first touched will push workpiece and turn round along the center line that two sides V-arrangement bearing 3 is formed, to make two sides
Support plate 14 can be bonded with workpiece, and such workpiece reaches horizontal attitude, complete and translation is helped to make.
13 oil inlet of oil cylinder pushes up extension bar 12, and extension bar 12 pushes wedge plungers 5 to move upwards, the wedge shape of wedge plungers 5
Inclined-plane pushes the mandril 6 of two sides to stretch out simultaneously, and the mandril 6 for first touching workpiece lumen at this time can head on workpiece and horizontally move
Workpiece, after other side mandril 6 touches workpiece lumen, workpiece stops transverse shifting, reaches the posture of centering.Oil cylinder 13 at this time
Pressure is kept, the mandril 6 of two sides just heads on always workpiece lumen, guarantees that workpiece does not have the possibility of axial float, completes at this time
Workpiece helps flat centering to act.
After process finishing, the piston rod of oil cylinder 13 is moved downward, and pulling extension bar 12, extension bar 12 pulls wedge plungers downwards
5 move downward, because of the T-slot structure between mandril 6 and wedge plungers 5, mandril 6 can be withdrawn under the action of inclined-plane T-slot,
Unclamp workpiece.
What is be not specifically noted in all description of the invention is the prior art or can be realized by existing technology,
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description, and it is all this
A little modifications and variations should all belong to the protection domain of appended claims of the present invention.
