Specific embodiment
The present invention is as shown in Figs. 1-5, and the locking device includes pedestal 41, friction plate 42, drive disk 43, spring 44, drives
Moving axis 45, cabinet 46, support column 47 and several clamp arm components；
The friction plate 42 is vertically arranged and is fixedly connected on the side of 41 top surface of pedestal, the cabinet 46 in hollow shape,
And it is fixedly connected on the other side of 41 top surface of pedestal, the drive shaft 45 is horizontally disposed and wears the cabinet 46, the driving
There are gap and the other end is removably connected with support column 47, the support column between one end of axis 45 and friction plate 42
47 and drive shaft 45 it is concentric；The center of the drive disk 43 be fixedly connected the drive shaft 45 close to friction plate 42 one end,
And the spring 44 is against between drive shaft 45 and cabinet 46, so that being against on friction plate under 43 normality of drive disk；
The middle part of the drive shaft 45 offers several external toothing teeth in cabinet 46, and the clamp arm component includes tooth
Item 481, connecting plate 482, connecting rod 483 and arc fixture block 484, the rack gear 481 wears the cabinet 46 and and drive shaft
External toothing tooth on 45 is meshed, and the connecting plate 482 is fixedly connected on one end that rack gear 481 is extend out to outside cabinet 46, described
The side that is radially arranged in support column 47 and one side end and connecting plate 482 stationary phase of the connecting rod 483 along drive shaft 45
Even, the fixture block 484 is fixedly connected on the one end of connecting rod 483 far from connecting plate 482.In use, operator can first basis
The internal diameter of aluminum pipe chooses corresponding support column, and completes being detachably connected for support column and drive shaft；Again by the termination point casing of aluminum pipe
If on the support columns；Hereafter, operator can first laterally urge drive disk, it is made to overcome the active force of spring and friction plate point
From, it is rotated further by drive disk, so that all connecting rods, fixture block while the radial motion along drive shaft, tightly from the outside of aluminum pipe
Clamp aluminum pipe, finally, unclamp drive disk, be against it on friction plate under the compressing of spring, complete aluminum pipe end point lock
Tightly；In this way, due to all having stable, effective support inside and outside aluminum pipe, clamping, it can effectively avoid aluminum pipe end rear
Occur deformation, damaged problem in continuous Cold Drawing Process.When practical application, settable two locking devices, the both ends to aluminum pipe are equal
After completing locking, pedestal can be pushed to slide, realize the cold-drawn to aluminum pipe.This case has delicate structure, easy to use on the whole
And it can effectively avoid the aluminum pipe end middle advantage for deformation, breakage occur after clamping.
The center of the support column 47 offers the stepped hole for accommodating bolt 470, and the drive shaft is towards support column
End face on offer fastening thread hole, the bolt is threadedly coupled with fastening thread hole.To realize support column and driving
Being detachably connected between axis.
The cabinet is square, and there are four the clamp arm component tools, and the rack gear in four clamp arm components is threaded through case respectively
