Abstract

The utility model relates to a rapid center shelf, relating to a device used for clamping and positioning in machine works. The utility model is composed of a shelf body and a small bracket. The utility model is characteristic in that the fastening method of the utility model is an upper hook body structure and a lower hook body structure, the small bracket is provided with a butterfly-shaped spring which can automatically compensate and plays a buffer function, and then the utility model has the advantages of rapid clamping of workpieces and reliable positioning, and the utility model protects the safe running of devices. The process of clamping and positioning can be completed in 1 second, and the utility model is more welcomed by machine working people.

Description

Rapid center frame

The utility model relates to the device of clamping location in a kind of processing, is a kind of quick centre frame specifically.

The centre frame that existing machined is used all adopts rigid structure, be to screw the centre frame upper body with screw rod, nut, this is for the not round workpiece of circumferential surface, cause rolling bearing to withstand shocks load suddenly easily and rupture, and centre frame is that employing screw rod, nut are fastening, speed is slow, wastes time and energy.

Task of the present utility model provides a kind of quick centre frame.

Technical solution of the present utility model is centre frame to be manufactured upper and lower coupler body structure adopt disk spring to realize the flexible structure of centre frame.Be to realize that by upper hook body 17 and lower hook body 20 clamping is fastening specifically, by 4 cushioning effects of butterfly spring.

Owing to adopted such scheme, its quick centre frame has been realized the quick-clamping location, has guaranteed the safe operation of equipment again.It can finish the clamping workpiece location one time in 1 second, and can compensate the equipment stability and safety automatically.

Embodiment:

That accompanying drawing is described is an embodiment of the present utility model.By shown in Figure 1, this quick centre frame is the improvement to prior art.The fastening means improvement that is about to centre frame becomes upper and lower coupler body structure, is installed in the butterfly spring that adds of upper body in three small racks, so that compensate automatically, plays cushioning effect, guarantees security of operation.

Centre frame integral body is divided upper and lower two halves fast, and its left side couples together with bearing pin, and the first half can be rotated around bearing pin.Its right binding end is established upper hook body 17 and lower hook body 20, and upper hook body 17 is fastened on centre frame body upper half part right-hand member by two straight pins 16; The right-hand member of lower portion is set coupler body 20, and it is to fasten with a bolt or latch on the centre frame body by horizontal door bolt 21, settles a straight pin 19 on the back of lower hook body 20, and be with spring 18, corresponding with the position of straight pin 19, on the centre frame body, open a spring eye, so that pack spring 18 into.At the promotion rod end of lower hook body 20, load onto drawing handle 22.When driving handle 22 left, compression spring 18, hook is just thrown off; When with the centre frame upper half part to pressing down, upper hook body 17 pushes away lower hook body 20 left by the inclined-plane of hook end, upper and lower hook hooks automatically, and is tightly pushed down and do not broken off relations by spring 18.

On the small rack 6 of quick centre frame, establish the butterfly spring device.Cover sliding sleeve 5 is debug pole 3 on the small rack 6 on the sliding sleeve 5, suit butterfly spring 4 on the adjusting rod 3, and dress lining 2 refills regulating handle 1 on it on lining 2.When workpiece is contained in the position of three supports 6 of centre frame, with top to after the center, with pulling moving miniature lever 10, as shown in Figure 2, the sulculus that locating shaft 8 is thrown off on the regulating handles 1.This sulculus is along the suitable uniform 18--36 bar of bus of the circumference of regulating handle 1, and present embodiment is 24.And then turn miniature lever 10, straight pin 12 is stuck in by spring 13 on the bearing-surface of splicing sleeve 9, and adjusting nut 14 and guider screw 15 can move sliding sleeve 5 at axial direction, small rack 6 is contained in the sliding sleeve 5 with interference fit, and lining 2 is fixed on the centre frame body by conical surface screw.Handle 1 and adjusting rod 3 are with straight pin 7 relative fixed.First-class workpiece, with regulating handle 1 appropriate location is transferred in the centre frame upper body, upper hook body 17 and lower hook body 20 can be hooked, promotion by spring 18 makes it not throw off, the turn miniature lever 10 again, straight pin 12 is stuck in the groove of splicing sleeve 9, and locating shaft 8 has also blocked in the sulculus on the regulating handle 1, makes it no longer to move in a circle.Finished the clamping and positioning of workpiece like this.

After the workpiece completion of processing, promote drawing handle 22, compression spring 18, last lower hook body is thrown off, and opens the centre frame upper body, unloads workpiece, next workpiece to be installed.
