Abstract
The utility model provides an inserted type double-head stud loading and unloading fixture which mainly comprises a fixture body, a holder, three rollers and a baffling ring, wherein an appropriate amount of grooves form a mold cavity of the fixture body, the holder is placed in the mold cavity and distributed with three cylindrical grooves, and the baffling ring is connected with the bottom of the fixture body through set screws. When assembled, the inserted type double-head stud loading and unloading fixture is inserted in a stud; when the fixture body is rotated, the holder is relatively still, groove faces in the mold cavity of the fixture body extrude the rollers, and therefore the stud is tightly clamped and clamping is convenient. After the stud is screwed tightly, the fixture body is slightly rotated to a reverse direction, and the fixture can be disassembled. The inserted type double-head stud loading and unloading fixture is convenient to clamp and withdraw, and can reduce labor intensity and improve working efficiency. Due to the fact that contacting points of the rollers and threads are many and abrasion-resistant bearing steel is adopted to produce, service life is long. Meanwhile, the inserted type double-head stud loading and unloading fixture can screw threads with different pitches and even screw a stud which is only provided with threads at one end and is wide in application range.

Groove quantity on the described chuck body is 3 multiple, and after loading and unloading clamp used the certain wearing and tearing of appearance, replaceable 1 cover roller was positioned in the new groove, can continue to use.
The about 0.2-0.7 millimeter of middle mind-set retainer external diameter skew of cylindrical groove on the described retainer.
Described roller adopts anti-friction bearing steel making, long service life.
Described baffle ring internal diameter is identical with the retainer internal diameter.
When assembling, owing to have the gap between double-screw bolt and the roller, only need be inserted in a kind of Novel stud loading and unloading clamp on the double-screw bolt and get final product, and clamping is very convenient; When the rolling clamp body, retainer is relatively static, chuck body die cavity inner groove faces extruding roller, thus clamping double-screw bolt, this moment can adopt pneumatic or hydraulic spanner is screwed into corresponding screw with double-screw bolt; Behind the screwing up stud, slightly to opposite spin chuck body, i.e. releasable clamp.
A kind of Novel stud loading and unloading clamp described in the utility model, moves back and unloads conveniently at clamping, can reduce labor intensity, increase work efficiency; Roller and screw thread contact point are many, and adopt anti-friction bearing steel making, long service life; Simultaneously, these anchor clamps can be tightened the screw thread of different pitch, even can tighten the only threaded double-screw bolt of an end, and are widely applicable.
