Abstract
A pipe fitting clamping device comprises a fixed frame, a movable frame, a handle and a transmission rod. The transmission rod is composed of an upper threaded rod and a lower threaded rod. The screw pitch of the upper threaded rod is larger than that of the lower threaded rod. The movable frame and the upper threaded rod are connected through threads. The fixed frame and the lower threaded rod are connected through threads. The lower end of the lower threaded rod is connected with an upper clamping block. A lower clamping block is fixedly arranged in the movable frame. The handle is fixedly arranged on the transmission rod. Due to the threaded rod transmission mode adopted in the clamping process, an upper chuck and a lower chuck of the clamping device simultaneously keep moving up and down relative to the fixed frame all the time, and therefore the machining efficiency is improved, and the clamping reliability is improved due to the adoption of the differential transmission.
Description
Technical field
The present invention relates to clamping tool for machine work technical field, particularly a kind of fixed clamping device for pipe fitting processing.
Background technology
During for building, maintenance sites processing tube screw thread, first the master die corresponding to pipe fitting diameter is arranged on die head, then pipe fitting is passed from clamp system, clamp after screw die.By starting switch, movable gas thread forming machine is started working, until machining screw length encounters travel switch reversion after putting in place, power-off quits work.Unclamp screw die, unload pipe fitting, gas thread forming process completes.Need during clamping pipe fitting pipe fitting circumference fixing, axially automatically follow up, no matter and pipe fitting diameter, require that the clamp central of pipe casting clamp keeps overlapping with die head pivot all the time.Existing pipe casting clamp is due to the restriction of clamping force, and cause in gas thread process, the phenomenon of slippage appears in pipe fitting, thus affects the crudy of gas thread; And each clamping all needs to carry out centering with processing pivot, reduces working (machining) efficiency.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide that a kind of structure is simple, reliable clamping, adopt differential fashion to carry out the pipe fitting cramping arrangement clamped.
For solving the problems of the technologies described above, present invention employs following technical scheme:
A kind of pipe fitting cramping arrangement, comprise fixed mount, adjustable shelf, handle and drive link, described drive link is made up of upper screw rod and lower screw rod, the pitch of described upper screw rod is greater than lower screw pitch, be threaded connection between described adjustable shelf and upper screw rod, be threaded connection between described fixed mount and lower screw rod, described lower screw rod lower end connects upper fixture block, adjustable shelf internal fixtion is provided with lower fixture block, and described handle is fixedly mounted on drive link.
The pitch of described upper screw rod is the twice of lower screw pitch.
Described upper fixture block and lower fixture block are provided with V-arrangement jaw.
The beneficial effect that the present invention has: this pipe fitting cramping arrangement utilizes screw drive mode, in the process of clamping, the upper and lower chuck of clamping device is remained relative to fixed mount move up and down simultaneously, no matter thus the size of pipe fitting, all the time make the center of fixture be consistent, thus avoid in process, to the adjustment of machining center, not only increase working (machining) efficiency, and improve the reliability of clamping because have employed differential gearing.

Fig. 1 is structural representation of the present invention.
In figure: 1, drive link; 11, upper screw rod; 12, lower screw rod; 2, adjustable shelf; 3, upper fixture block; 4, lower fixture block; 5, handle; 6, fixed mount; 7, V-arrangement jaw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, for a kind of pipe fitting cramping arrangement, comprise fixed mount 6, adjustable shelf 2, handle 5 and drive link 1, described drive link 1 is made up of upper screw rod 11 and lower screw rod 12, and the pitch of described upper screw rod 11 is greater than lower screw rod 12 pitch, is threaded connection between described adjustable shelf 2 and upper screw rod 11, be threaded connection between described fixed mount 6 and lower screw rod 12, described lower screw rod 12 lower end connects upper fixture block 3, and adjustable shelf 2 internal fixtion is provided with lower fixture block 4, and described handle 5 is fixedly mounted on drive link 1.
In the present invention, the pitch of described upper screw rod 11 is the twice of lower screw rod 12 pitch; When rotating drive link 1, upper and lower pressing plate always makes move toward one another relative to fixed mount 6 with identical speed, thus realize upper and lower pressing plate simultaneously near or simultaneously away from clamping device center, ensure that clamping device center does not change with the change of pipe fitting diameter dimension.
In the present invention, described upper fixture block 3 and lower fixture block 4 are provided with V-arrangement jaw 7, add the contact surface between pipe fitting.The clamping force of clamping device can be improved.
When turn clockwise drive link 1 time, upper screw rod 11 and lower screw rod 12 are right-handed thread, fixed mount 6 relative to the upper fixture block 3 that drive link 1 connects moves down, the relative drive link 1 of lower platen 4 on adjustable shelf 2 is rotated counterclockwise and moves, thus realizes quick position, clamping to the pipe fitting between upper and lower pressing plate.
