Description

Fixture box in a kind of tool joint
Technical field
The present invention relates to a kind of Fixture box in slush pump tool joint.
Background technology
Slush pump tool joint before welding, must be done the shackle experiment on joint, make screw thread and loading end obtain corresponding load, the every cooperation of joint is checked, thus the possibility that minimizing screw thread is pierced through by mud.
In prior art, when shackle, above unload when promptly unclamping, because moment of torsion inertia is large, on unload the deviation of pressure, be very easy to damage joint, also have some problems to be do not reach torque demand in addition, unsightly, length consuming time is tested in shackle to joint surface, the problems such as inefficiency.
Summary of the invention
Technical problem to be solved by this invention is that break-out torque is unstable, inefficiency, therefore, the invention provides a kind of Fixture box of quick, convenient, torque levels.
In order to solve the problems of the technologies described above, the invention provides the Fixture box in a kind of tool joint, described Fixture box is mainly made up of housing, the location case being positioned at shell one end and the locking case that is positioned at the housing other end, a fixed piston is had in the case of described location, a latching ram is had in described locking case, described fixed piston and latching ram end are all provided with pliers, are all provided with buffer in the both sides of housing.
Further, described pliers is made up of die block, pliers die insert and pliers apron strip, described die block is fixed on described fixed piston and latching ram end, described pliers die insert is fixed on die block, described pliers apron strip is fixed on described fixed piston and latching ram end, in order to fixing die block and pliers die insert.
Further again, described fixed piston and latching ram are by hydraulic-driven, and described buffer partial installation is in tank shell portion, location, clamping housing section and lock tank shell portion.
Beneficial effect of the present invention is:
1, technical solution of the present invention adopts in Fixture box housing and is provided with positioning piston and latching ram, positioning piston and latching ram movement locus are stablized, and in relatively airtight grasping part, therefore, the torsional moment of clamping is stable, also there will not be external injury phenomenon.
2, technical solution of the present invention adopts hydraulic power to drive clamping, and pressure stability and adjustability are strong, and positioning piston, a latching ram coordinate, and action is simple, and operating efficiency is high, and has buffer to make buffer protection.
3, technical solution of the present invention adopts closure design, and rational in infrastructure, function admirable is practical.
