Abstract
The utility model provides a special fixture for a rebar. The special fixture for the rebar comprises a cylindrical rotatable lock sleeve. The side edge of the lock sleeve is provided with an opening. A fixed lock core is arranged inside the lock sleeve. The side edge of the lock core is also provided with an opening and a lock core bushing is arranged at the opening of the lock core, wherein the section of the lock core bushing is of a concave semicircular structure; the size of the lock core bushing can enable the rebar to be clamped; the lock core bushing is provided with a plurality of grooves; the groove structures of the lock core bushing correspond to the positions of screw threads on the surface of the rebar. A locking screw is inserted and arranged into the surface of the lock sleeve. The locking screw passes through the lock sleeve so as to compress the lock core. According to the special fixture, wear to the rebar can be reduced; the aim of rapidly clamping the rebar can be fulfilled only by manual operation without using other stress application tools; the special fixture for the rebar is labor-saving and time-saving and is economic and reliable.
Description
Technical field
The utility model relates to fabrication of reinforcing cage technical field, refers more particularly to a kind of spiral special fixture.
Background technology
At present common steel reinforcement cage forming machine spiral fixture used is as Fig. 1, that spiral is put in to sleeve, with the bolt on sleeve, hold out against again, puller bolt termination acts directly on spiral surface, because spiral outer surface has two symmetrical straightedges and asymmetrical, a plurality of crescent moon corner angle that are evenly arranged, puller bolt termination usually acts on corner angle or above straightedge, puller bolt, it between spiral and sleeve fixture, is some contact, easily producing relative sliding or spiral rotates, use boosting-rod to tight a bolt, forming machine can cause spiral twisting while rotating, very easily loosening, directly affect steel reinforcement cage Forming Quality, cause spiral location inaccurate, steel reinforcement cage is in aperture docking difficulty.And the easy loss of puller bolt, often change, operate time-consumingly, the reliability of this fixture, economy are all undesirable.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency over against above-mentioned existence, a kind of spiral wearing and tearing that alleviate are provided, need just can not realize the object of Quick-clamped spiral by other force-multiplier tool is only hand-manipulated, saving of work and time, economic spiral special fixture reliably.
The utility model solves the technical scheme that its technical problem adopts:
Spiral special fixture, it is characterized in that: the rotatable lock tube that includes a tubular, lock tube side is with opening, lock tube inside is provided with fixing lock core, and the side of lock core is also with opening, and at the opening part of lock core, lock core lining is installed, wherein the cross section of lock core lining is indent semi-circular structure, its size can be blocked spiral, and with a plurality of grooves, its groove structure is corresponding with spiral thread surface position; Described lock tube surface is inserted tie down screw is installed, and tie down screw can compress lock core through lock tube.
In such scheme, described lock core lining is embedded on lock core, with lock core be separable structure.
In such scheme, described plug face is provided with a circle chute along circumference, and the position of chute is over against tie down screw, for tie down screw clamping location.
In such scheme, the concave surface area of described lock core lining, is less than 1/2nd of spiral exterior surface area.
The operation principle of this special fixture is to make full use of spiral resemblance, making special use, stressed working face and spiral have a consistent fixture lining of corner angle facial contour, make the working face area of lining be slightly less than the external surface area of 1/2 spiral, allow lining working face can and spiral outer surface two straightedges between, there is one side of something of angle rib to be close together, again the lock core lining being close together and spiral are put in sizeable lock tube, now two of spiral straightedges lean against lining outer ledge, its angle rib of being close to lining can enter in working face corresponding recesses, it between lock core lining and spiral, is face contact, just can not there is relative motion, reach the object of Quick-clamped spiral.Not only improve effect, and significantly promote steel reinforcement cage Forming Quality.
The utility model compared with similar products, has advantages of following main:
The utility model device can alleviate spiral wearing and tearing, need just can not realize the object of Quick-clamped spiral by other force-multiplier tool is only hand-manipulated, and saving of work and time is economical reliable.

The specific embodiment
Below in conjunction with the specific embodiment, to the utility model, embodiment is further described:
Referring to Fig. 1 to Fig. 3:
Spiral special fixture, include the rotatable lock tube 5 of a tubular, lock tube 5 sides are with opening, and lock tube 5 inside are provided with lock core 4, and lock core 4 is fixedly mounted on lock core erection support 2, the side of lock core 4 is also with opening, and at the opening part of lock core 4, lock core lining 3 is installed, and wherein the cross section of lock core lining 3 is indent semi-circular structure, its size can be blocked spiral, and with a plurality of grooves, its groove structure is corresponding with spiral thread surface position; Described lock tube 5 surfaces are inserted tie down screw 1 are installed, and tie down screw 1 can compress lock core 4 through lock tube 5.
In the present embodiment, described lock core lining 3 is embedded on lock core 4, with lock core 4 be separable structure.
In the present embodiment, described lock core 4 surfaces are provided with a circle chute 6 along circumference, and the position of chute 6 is over against tie down screw 1, for tie down screw 1 clamping location.
In the present embodiment, the indent semicircle surface area of described lock core lining 3, is less than 1/2nd of spiral exterior surface area.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not depart from scope and spirit of the present utility model the utility model.If these changes and distortion belong to the scope of the utility model claim and equivalent technologies thereof, intention of the present utility model also comprises these changes and is out of shape interior.
