Convenient, service life length is applied widely, easy to promote the use of.
To achieve the above object, the technical solution adopted in the utility model is：A kind of combined type columnar workpiece self-locking clamps
Device, including the base playing fixed supporting role, it is characterised in that：Further include the screw thread for compressing columnar workpiece to be processed
Bar and the shaft form the inner thread sleeve of screw-driven pair and lower end is provided with the door shape branch of T-slot connector
Frame；The V-shaped groove for preventing columnar workpiece to be processed from rolling is provided with the upside of the base, is located at the V on the upside of the base
Shape groove both sides are symmetrically arranged with T-slot, and the T-slot joint sliding that the portal trestle lower end is set is sleeved on the T of the base
In shape groove, the inner thread sleeve is installed with the upside of the portal trestle, is provided with the inside of the inner thread sleeve described
The driving handle for being useful for driving the threaded rod to rotate is fixedly mounted in threaded rod, the threaded rod upper end.
Combinations of the above formula columnar workpiece self clamping device, it is characterised in that：The V-shaped groove is arranged on the base
Middle side part.
Combinations of the above formula columnar workpiece self clamping device, it is characterised in that：The threaded rod lower end, which is provided with, to be used for
Prevent from damaging the flexible pressure head of columnar workpiece outer contour to be processed.
Combinations of the above formula columnar workpiece self clamping device, it is characterised in that：The inner thread sleeve is welded on described
On the upside of portal trestle.
The utility model has the following advantages compared with prior art：
(1) combined type columnar workpiece self clamping device design is very reasonable, and columnar workpiece is clamped by screw thread pair, because
And its reliable clamping, reinforcement are big, can self-locking and stroke it is unrestricted.
(2) the combined type columnar workpiece self clamping device uses modular design, convenient for disassembly and assembly, easy to carry and fortune
It is defeated.
(3) the combined type columnar workpiece self clamping device structure is very simple, and operating personnel only need rotation driving handle
Columnar workpiece is may tighten or loosen, operation is very easy.
(4) rigid shock is not present in the combined type columnar workpiece self clamping device in use, thus it is used
Service life is very long.
(5) the combined type columnar workpiece self clamping device is applicable not only to technical field of mechanical processing, applies also for it
