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, connecting portion, arc
The resilient attachment arms and snap ring of shape, the snap ring side is installed in the ring-type neck on the outside of receiver Nei, its opposite side is distributed with
Some resilient attachment arms, the resilient attachment arms are fixedly connected towards lateral bend outside snap ring and by connecting portion with chuck, described
Connecting portion is from close to one end of resilient attachment arms, to close to one end of chuck gradually wealthy pyramidal structure, the base sleeve leading section is set
There is a spring for leaning the chuck, 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 fixture of the present invention, receiver is moved back in the presence of drive device along base sleeve axle, drives clamping jaw synchronous
After move, the cone connection of clamping jaw under the limitation of sleeve to contract, and then cause clamping jaw chuck position clamp copper pipe;Drive
In the case of dynamic device is adiaphorous to receiver, clamping jaw along base sleeve axial advancement, drives receiver reach under the action of the spring,
Resilient attachment arms expand outwardly, and chuck position unclamps copper pipe.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.
Embodiment
As depicted in figs. 1 and 2, including for clamping the clamping jaw of copper pipe, and sleeve 2, sleeve rack 18, 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 18 is fixedly connected, specifically, the radially outer edge face of sleeve 2 is provided with flange 19, the flange 19 of sleeve 2 is flush-mounted in sleeve rack 18
Mounting groove in and be bolted connection, sleeve rack 18, pedestal 5 are fixed on the support of copper pipe perforating press, receiver 3
Moved axially in the presence of drive device along base sleeve 4.Clamping jaw includes chuck 11, connecting portion 14, the resilient attachment arms of arc shape
13 and snap ring 12, the side of snap ring 12 is installed in the ring-type neck 15 in the outside of receiver 3, its opposite side is distributed with along annular end face
Some resilient attachment arms 13, snap ring 12 are fixedly connected with ring-type neck 15 by bolt 16, and resilient attachment arms 13 are towards snap ring 12
Outer lateral bend is simultaneously fixedly connected by connecting portion 14 with chuck 11, and some chucks are located on the outside of sleeve, for clamping copper jointly
Pipe, connecting portion 14 be from close to one end of resilient attachment arms 13 to before one end of chuck 11 gradually wealthy pyramidal structure, base sleeve 4
End, which is provided with, leans the spring 17 of chuck 11, and spring 17 can make clamping jaw, receiver 3 along base sleeve axial advancement.
Drive device includes cylinder 61, cylinder block 62, lever 66 and lever seat 67, and cylinder 61 is installed on cylinder block 62, gas
The both sides of cylinder seat 62 are supported on support 63 by first rotating shaft 64 respectively, and one end of lever 66 passes through the second rotating shaft 68 and cylinder 61
First 65 connection of the push-and-pull of output end, its fulcrum location are connected by the 3rd rotating 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 provided with
Two and receiver radially opposite sides are symmetricly set in, 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 rotating shaft 69
Rotation, Cam Follower 60 move after driving receiver 3, clamping jaw, and the cone connection 14 and resilient attachment arms 13 of clamping jaw are covering
To contract under the limitation of cylinder 2, and then the chuck 11 of clamping jaw is caused to clamp copper pipe;Cylinder piston rod 611 is retracted, and drives lever 66
Turned clockwise around the 3rd rotating shaft 69, Cam Follower 60 is to receiver without effect, and clamping jaw is in the presence of spring 17 along base sleeve
Axial advancement, receiver 3 is driven to move forward, resilient attachment arms 13 expand outwardly, and chuck 11 unclamps 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 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
Loosen.
