Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, complete description, it is clear that described embodiment is only that a part of the utility model is embodiment, rather than all
Embodiment.Based on the embodiments of the present invention, those skilled in the art are without making creative work
All other embodiment obtained, belongs to the protection scope of the utility model.
Please refer to attached drawing 1-3, it is a kind of for the automatic of lathe in machining Automobile balance shaft in the utility model embodiment
Change fixture, including rotation terminal pad 1, one group of prelocalization column 3 is installed on the rotation terminal pad 1, is positioned after one
Column 15, rotating mechanism pedestal 2 is mounted in rotation terminal pad 1 by oil dividing plate 12 before one group, rotating mechanism pedestal 11 after one group;
It is separately installed with initial alignment pin 14 and precision positioning mechanism 13 on one group of prelocalization column 3, is rotated before described one group
Rotating cylinder 4 before being separately installed on mechanism base 2 rotates clamp system 5, institute before being separately installed on the preceding rotating cylinder 4
It is separately installed with preceding adjusting screw 6 on the preceding rotation clamp system 5 stated, is separately installed on rotating base 11 after described one group
Rotating cylinder 10 afterwards rotate clamp system 9, the rear rotation clamp system 9 after being respectively provided on the rear rotating cylinder 10
On be separately installed with after the screw 8 that adjusts.
Preferably, one group of prelocalization column upper surface is respectively arranged with airtight detection hole.
Preferably, one group of prelocalization column 3 is arranged in the rotation at Y type with the rear positioning column 15 and connects
On disk 1.
Preferably, hanging ring 16 is installed in the rotation terminal pad 1.
Further, further include spindle coupling disc 18, the rotation terminal pad 1 by the spindle coupling disc 18 with
Rotate axis connection.
Further, multiple groups pipeline 17 is installed in the rotation terminal pad 1.
The working principle of the utility model are as follows: preceding rotation clamp system 5 and rear rotation clamp system 9 are in the open state,
At this point, precision positioning mechanism 13 is in releasing orientation, rotating cylinder detects itself air-tightness automatically, starts feeding, one group of prelocalization
Column 3 detects feeding end face air-tightness, and after material is put just, precision positioning mechanism 13 is clamped, preceding rotation clamp system 5 and rear rotating clamp
Whether rotation clamp system 5 rotates clamp system 9 with rear before the tight clamping of mechanism 9, preceding rotating cylinder 4 and rear rotating cylinder 10 detect respectively
It clamps, starts to process part after clamping.
Specifically, when the oil circuit of rotation clamp system 5 and rear rotation clamp system 9 unclamps before control, preceding rotation clamping machine
Structure 5 and rear rotation clamp system 9 unclamp, while rising and being rotated by 90 °, rotate at this time airtight detection to rotation clamp system whether
Release is detected in place, indicates to detect position when airtight pressure rises, system carries out feeding request to manipulator, in manipulator
In feeding process, coarse positioning need to be carried out to workpiece 7 by initial alignment pin 14, workpiece 7 is then placed on one group of prelocalization column 3
And on the end face of rear positioning column 15.It is fixed before one group at this time when manipulator, which completes feeding, to be acted and issue processing request signal
The airtight detection hole of position column 3 upper surface to workpiece 7 carry out airtight detection, detection workpiece 7 and prelocalization column 3 and rear positioning column 15 it
Between whether contact good, when pressure switch has detected pressure, indicate that workpiece 7 is put into initial manufacture position completely.This
When hydraulic station to pipeline 17 issue action signal;Control precision positioning mechanism 13 is accurately positioned workpiece, while passing through control
It makes preceding rotating cylinder 4 and rear rotating cylinder 10 and rotation pinching action is carried out to preceding rotation clamp system 5 and rear rotation clamp system 9.When
After the completion of pinching action, system carries out pinching action to compress airtight detection.After detection is rotated in place, closes machine tool door and carry out vehicle
Cut processing.
After turnery processing, main shaft fixes fixture stop position using rotational positioning, to guarantee next feeding
Angular position.Machine tool door is opened, and accurate positioning device 13 is unclamped, and preceding rotation clamp system 5 and rear rotation clamp system 9 are beaten
It opens.The position unclamped to preceding rotation clamp system 5 and rear rotation clamp system 9 carries out rotation air-leakage test, works as pressure switch
Manipulator blanking request is issued after receiving signal.After blanking, for guarantee positioning end face on do not have iron filings need to the mechanism into
Row rotation blows bits movement, wait rotate blow bits movement finish, lathe realizes that standard stops function again.At this moment manipulator proposes feeding again
Request prepares the feeding of next processing unit.
Artificial Clamp blocks are converted into automation and clamp workpiece by the utility model.Manpower is saved, is made originally artificial upper and lower
Material becomes manipulator feeding, discharge, and can Automatic-clamping.Automatic detection Clamp blocks, uniform stressed, guarantee accurate work piece positioning,
It is firm to clamp.The yield of part is greatly improved, both saves cost of labor, in turn ensures the precision of part.
It will be apparent to a person skilled in the art that the utility model is not limited to the details that above-mentioned demonstration is embodiment,
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.
