The copper pipe clamp of copper pipe perforating press
The present invention relates to copper pipe punching apparatus, and in particular to the copper pipe clamp of copper pipe perforating press.
At present, the copper pipe clamp of copper pipe perforating press includes support base, clamping plate and bolt and nut component, and copper pipe is positioned over support
In the locating slot of seat, clamping plate is installed in locating slot, and can be moved up and down along the depth direction of locating slot, and clamping plate is in bolt
The lower clamping copper pipe of push effect, and pass through nut check.Existing copper pipe clamp clamping takes, efficiency is low.
The content of the invention
In view of the above-mentioned problems, the present invention provides the copper pipe clamp of copper pipe perforating press, it causes, and copper pipe clamping is quick, efficiency
It is high.
Its technical solution is such, it includes being used for the clamping jaw for clamping copper pipe, it is characterised in that：Its further include sleeve,
Receiver, base sleeve, pedestal and driving device；The base sleeve is installed on pedestal, and the receiver, the sleeve are set in successively
The base sleeve, the receiver are fixedly connected with the base sleeve, and the sleeve axially moves under the action of driving device along base sleeve
It is dynamic；The clamping jaw includes collet, connecting portion, the resilient attachment arms and snap ring of arc shape, and the snap ring side is installed in receiver
In the ring-type card slot in outside, its opposite side be distributed with some resilient attachment arms, the resilient attachment arms towards lateral bend outside snap ring,
And be fixedly connected by connecting portion with collet, the connecting portion is from one end of close resilient attachment arms to close to one end of collet
Gradually wealthy pyramidal structure.
It is further characterized by：
The driving device includes cylinder, cylinder block, lever and lever seat, and the cylinder is installed on cylinder block, the gas
Cylinder seat both sides are supported on stent by first rotating shaft respectively, and one end of the lever is defeated by the second shaft and the cylinder
Outlet connection, its fulcrum location is connected by the 3rd shaft with the lever seat, its other end is connected with Cam Follower, described
Cam Follower is located between bottom face and the receiver base flange of the sleeve.
The output terminal of the cylinder includes piston rod and the push-and-pull head being connected with piston rod thread, the rotation of the push-and-pull head
It is coaxially disposed into direction and the telescopic direction of the piston rod, one end of the lever passes through the second shaft and the push-and-pull head
End connects, and locking nut is also threaded with the piston rod.
Copper pipe clamp using the present invention, sleeve is under the action of driving device along base sleeve axial advancement so that clamping jaw
Cone connection is to contract, so that the chuck position of clamping jaw clamps copper pipe；In the case of driving device is adiaphorous, clamping jaw
Cone connection expanded outwardly under the action of resilient attachment arms so that after sleeve move and chuck position unclamp copper pipe.This
The copper pipe clamp of invention make it that copper pipe clamping is quick, efficient.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the attachment structure schematic diagram of clamping jaw of the invention, sleeve and receiver.
As depicted in figs. 1 and 2, including for clamping the clamping jaw of copper pipe, and sleeve 2, receiver 3, base sleeve 4,5 and of pedestal
Driving device.Base sleeve 4 is installed on pedestal 5, and receiver 3, sleeve 2 are set in base sleeve 4 successively, and receiver 3 is fixed with base sleeve 4 to be connected
Connect, sleeve 2 moves axially under the action of driving device along base sleeve 4.Clamping jaw includes collet 11, connecting portion 14, the bullet of arc shape
Property linking arm 13 and snap ring 12, if 12 side of snap ring is installed in the ring-type card slot 15 in the outside of receiver 3, its opposite side is distributed with
Dry elasticity linking arm 13, snap ring 12 are fixedly connected with ring-type card slot 15 by bolt 16, and resilient attachment arms 13 are towards outside snap ring 12
Lateral bend is simultaneously fixedly connected by connecting portion 14 with collet 11, connecting portion 14 be from close to resilient attachment arms 13 one end to by
One end of nearly collet 11 gradually wealthy pyramidal structure.
Driving device includes cylinder 61, cylinder block 62, lever 66 and lever seat 67, and cylinder 61 is installed on cylinder block 62, gas
62 both sides of cylinder seat are supported on stent 63 by first rotating shaft 64 respectively, and one end of lever 66 passes through the second shaft 68 and cylinder 61
First 65 connection of the push-and-pull of output terminal, its fulcrum location are connected by the 3rd shaft 69 with lever seat 67, its other end be connected with it is convex
Follower 60 is taken turns, Cam Follower 60 is located between the bottom face of sleeve 2 and the base flange 31 of receiver 3, and lever 66 is equipped with
Two and receiver radially opposite sides are symmetrically disposed on, two levers can consolidate integral by connecting rod, it is ensured that it is synchronized with the movement,
Can be two independent structures.As shown in Figure 1, cylinder piston rod 611 stretches out, drive lever 66 counterclockwise around the 3rd shaft 69
Rotation, Cam Follower 60 expand outwardly sleeve 2 without effect, collet 11 under the action of resilient attachment arms 13, and sleeve 2 departs from
The connecting portion 12 of clamping jaw, so as to unclamp copper pipe；Cylinder piston rod 611 is retracted, and drives lever 66 to be revolved clockwise around the 3rd shaft 69
Turn, the Cam Follower 60 on the other end of lever 66 acts on clamping jaw with moving sleeve 2 along 4 axial advancement of base sleeve, the reach of sleeve 2
Connecting portion 12, it is overcome the active force of resilient attachment arms to contract, so as to clamp copper pipe.
The piston rod 611 of cylinder 61 is threadedly coupled with push-and-pull first 65, precession direction and the cylinder piston rod 611 of push-and-pull first 65
Telescopic direction be coaxially disposed, one end of lever 66 is connected by the second shaft 68 with the end of push-and-pull first 65, cylinder piston rod
Locking nut is also threaded with 611, which is not shown.Driving is adjusted by the spinning in and out for pushing and pulling head
The size of the power of device output, and then adjust the clamping force that clamping jaw clamps copper pipe；The setting of locking nut can prevent push-and-pull head
