Description
Technical field
The present invention relates to fabrication of reinforcing cage technical field, refer 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, hold out against with the bolt on sleeve again, puller bolt termination acts directly on spiral surface, because spiral outer surface has two symmetrical straightedges and asymmetrical, the multiple 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 rotation, 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, reliability, the economy of this fixture are all undesirable.
Summary of the invention
Technical problem to be solved by this invention is the technical deficiency to above-mentioned existence just, provide one to alleviate spiral wearing and tearing, need be by the only object that just can realize Quick-clamped spiral hand-manipulated of other force-multiplier tool, saving of work and time, economical spiral special fixture and assembly method reliably.
The technical solution adopted for the present invention to solve the technical problems is:
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 multiple 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 just to 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.
While using this fixture to carry out spiral assembling, carry out in accordance with the following steps:
The special fixture of making is fixed by bolts on reinforcing bar shaper pallet, replaces former fixture;
Select the lock core lining of corresponding fixture and be arranged on fixed lock core according to spiral diameter; The shape of working surface of fixture lock core lining is consistent with spiral external surface shape, when installation, only need to by the working face of lock core lining outwardly and aim at the corresponding indentation, there of lock core, when replacing, outwards choose from the joint portion of lock core lining and lock core with flat mouth screwdriver.
Rotatable opening lock tube is installed; By lock tube, Open Side Down, make tie down screw on lock tube face the direction of lock core lining working face, be stuck in from outside to inside the outer surface of lock core, and make tie down screw termination aim at the chute on lock core, rotate counterclockwise lock tube, make the termination of tie down screw enter the chute of lock core.Need to change opening lock tube time, only need to rotate lock tube, by it, Open Side Down, makes tie down screw face the working face direction of lock core lining, outwards extracts lock tube simultaneously.
Rotate lock tube, make its opening direction consistent with the opening direction of lock core lining, now the working face of lock core lining is outwardly open;
Put into spiral from the opening part of lock tube, make it have angle faceted pebble and lock core lining working face to be close to, rotate counterclockwise lock tube approximately 90 degree simultaneously, make lock tube and lock core lining wrap spiral completely, now turn clockwise, tighten tie down screw, eliminate as possible the gap between lock core lining, spiral and lock tube, reach the object that clamps spiral, reverse operating is detachably by folder spiral.
The operation principle of this special fixture is to make full use of spiral resemblance, make special, 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 present invention compared with similar products, has advantages of following main:
Apparatus of the present invention can alleviate spiral wearing and tearing, need be by the only objects that just can realize Quick-clamped spiral hand-manipulated of other force-multiplier tool, and saving of work and time, economical reliable.
