Folder is quick, efficiency high.
Its technical scheme is such, and it includes being used for the clamping jaw for clamping copper pipe, it is characterised in that：Its also include sleeve,
Sleeve rack, receiver, base sleeve, pedestal and drive device；The base sleeve is installed on pedestal, the receiver, the sleeve according to
Secondary to be set in the base sleeve, the sleeve is fixedly connected with sleeve rack, and the sleeve rack, pedestal are fixed on the machine of copper pipe perforating press
On seat, the receiver moves axially in the presence of drive device along base sleeve；The clamping jaw includes chuck and linking arm, described
Linking arm end is stretched into the sleeve and is connected by articulated elements with receiver outer wall, and the chuck passes through with the linking arm
Connecting portion is connected, the connecting portion be from close to one end of linking arm to close to one end of chuck gradually wealthy pyramidal structure, it is described
Base sleeve leading section, which is provided with, leans the spring of the chuck, and the spring can make the clamping jaw, receiver along base sleeve axial advancement.
It is further characterized by：
The radially outer edge face of the sleeve is provided with flange, the flange of the sleeve in the mounting groove of sleeve rack,
And it is bolted connection.
The drive 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 support by first rotating shaft respectively, and one end of the lever is defeated by the second rotating shaft and the cylinder
Go out end connection, its fulcrum location is connected by the 3rd rotating 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 end 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
Enter direction and the telescopic direction of the piston rod is coaxially disposed, one end of the lever passes through the second rotating shaft and the push-and-pull head
End is connected, and locking nut is also threaded with the piston rod.
Using the copper pipe clamp of the present invention, receiver is moved back in the presence of drive device along base sleeve axle, drives clamping jaw
Moved after synchronization, to contract under the limitation of the taper position sleeve of clamping jaw, and then cause the chuck position of clamping jaw to clamp copper pipe；Drive
In the case of dynamic device is adiaphorous to receiver, clamping jaw, receiver are under the drive of spring along base sleeve axial advancement, the folder of clamping jaw
Unclamp copper pipe in head position.The copper pipe clamp of the present invention make it that copper pipe clamping is quick, efficiency high.
Brief description of the drawings
Fig. 1 is the structural representation 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, sleeve rack 16, receiver 3, base sleeve
4th, pedestal 5 and drive device.Base sleeve 4 is installed on pedestal 5, and receiver 3, sleeve 2 are set in base sleeve 4, sleeve 2 and sleeve successively
Frame 16 is fixedly connected, specifically, the radially outer edge face of sleeve 2 is provided with flange 15, the flange 15 of sleeve 2 is flush-mounted in sleeve rack 16
Mounting groove in and be bolted connection, sleeve rack 16, pedestal 4 are fixed on the support 1 of copper pipe perforating press, receiver 3
Moved axially in the presence of drive device along base sleeve 4.Some clamping jaws surround 3 weeks EDS maps of receiver, and clamping jaw includes chuck 11
With linking arm 13, the medial surface of chuck agrees with for arc-shaped, with copper pipe outer surface, and some chucks are located on the outside of sleeve, for altogether
With clamping copper pipe, and settable rubber blanket prevents copper pipe from wearing；The end of linking arm 13 stretch into sleeve 2 and by articulated elements 17 with
The outer wall of receiver 3 connects；Chuck 11 is connected with linking arm 13 by connecting portion 12, and connecting portion 12 is by close to the one of linking arm 13
Hold to close to one end of chuck 11, gradually wealthy pyramidal structure, the leading section of base sleeve 4 are provided with the spring 14 for leaning chuck 11, the energy of spring 14
Enough make clamping jaw, receiver 3 along the axial advancement of base sleeve 4.
Drive device includes cylinder 61, cylinder block 62, lever 66 and lever seat 67,61 preferred double-acting cylinder of cylinder, gas
Cylinder 61 is installed on cylinder block 62, and the both sides of cylinder block 62 are supported on support 63 by first rotating shaft 64 respectively, one end of lever 66
It is connected by the second rotating shaft 68 with the push-and-pull first 65 of the output end of cylinder 61, its fulcrum location passes through the 3rd rotating shaft 69 and lever seat 67
Connection, its other end are connected with Cam Follower 60, and Cam Follower 60 is located at the bottom face of sleeve 2 and the bottom of receiver 3
Between flange 31, lever 66 is provided with two and is symmetricly set in receiver radially opposite sides, and two levers can be consolidated into by connecting rod
One is overall, it is ensured that is synchronized with the movement or two independent structures.As shown in figure 1, cylinder piston rod 611 stretches out, thick stick is driven
Bar 66 moves around the rotate counterclockwise of the 3rd rotating shaft 69, Cam Follower 60 after driving receiver 3, clamping jaw, the taper position set of clamping jaw
To contract under the limitation of cylinder, and then the chuck position of clamping jaw is caused to clamp copper pipe；Cylinder piston rod 611 is retracted, and drives lever
66 turn clockwise around the 3rd rotating shaft 69, Cam Follower 60 to receiver without effect, clamping jaw, receiver 3 spring 14 band
Under dynamic copper pipe is unclamped along the axial advancement of base sleeve 4, the position of chuck 11 of clamping jaw.
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 rotating shaft 68 with the end of push-and-pull first 65, cylinder piston rod
Locking nut is also threaded with 611, the locking nut is not shown.Driving is adjusted by the spinning in and out of push-and-pull 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
