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
Steel reinforcement cage forming machine common at present spiral fixture used is as Fig. 1, that spiral is put in 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 be evenly arranged, puller bolt termination usually acts on above corner angle or straightedge, puller bolt, it is point cantact between spiral and sleeve fixture, easy generation relative sliding or spiral rotate, namely boosting-rod is used to tight a bolt, forming machine can cause spiral to twist when rotating, very easily loosening, directly affect steel reinforcement cage Forming Quality, spiral is caused to locate inaccurate, steel reinforcement cage is in aperture docking difficulty.And the easy loss of puller bolt, often to change, operate time-consuming, reliability, the economy of this fixture are all undesirable.
Summary of the invention
Technical problem to be solved by this invention is just to the technical deficiency of above-mentioned existence, one is provided to alleviate spiral wearing and tearing, need by other force-multiplier tool only object that just can realize Quick-clamped spiral hand-manipulated, 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 including a tubular, lock tube side is with opening, lock tube inside is provided with fixing lock core, and the side of lock core also with opening, and is provided with lock core lining at the opening part of lock core, wherein the cross section of lock core lining is indent semi-circular structure, its size can block spiral, and with multiple groove, its groove structure is corresponding with spiral thread surface position; Described lock tube surface is inserted and is provided with tie down screw, and lock core can compress through lock tube by tie down screw.
In such scheme, described lock core lining is embedded on lock core, is separable structure with lock core.
In such scheme, described plug face is circumferentially provided with a circle chute, and the position of chute, just to tie down screw, is located for tie down screw clamping.
In such scheme, the concave surface area of described lock core lining, is less than 1/2nd of spiral exterior surface area.
When using this fixture to carry out spiral assembling, carry out in accordance with the following steps:
The special fixture made is fixed by bolts on reinforcing bar shaper pallet, replaces former fixture;
Select the lock core lining of corresponding fixture according to spiral diameter and be arranged on fixed lock core; The shape of working surface of fixture lock core lining is consistent with spiral external surface shape, only need during installation by the working face of lock core lining outwardly and aim at the corresponding indentation, there of lock core, outwards to choose with the joint portion of flat mouth screwdriver from lock core lining and lock core during replacing.
Rotatable opening lock tube is installed; By lock tube, Open Side Down, make the tie down screw on lock tube face the direction of lock core lining working face, be stuck in the outer surface of lock core from outside to inside, and make the chute on the aligning lock core of tie down screw termination, rotate counterclockwise lock tube, make the termination of tie down screw enter the chute of lock core.When needing to change opening lock tube, 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;
Spiral is put into from the opening part of lock tube, it is made to have angle faceted pebble and lock core lining working face to be close to, rotate counterclockwise lock tube about 90 degree simultaneously, lock tube and lock core lining is made to wrap spiral completely, now turn clockwise, tighten tie down screw, eliminate as possible lock core lining, gap between spiral and lock tube, reach the object of clamping spiral, reverse operating is namely detachably by folder spiral.
The operation principle of this special fixture makes full use of spiral resemblance, make special, the fixture lining having corner angle facial contour consistent of stressed working face and spiral, the face area of lining is made to be slightly less than the external surface area of 1/2 spiral, allow between the working face energy of lining and spiral outer surface two straightedge, one side of something of angle rib is had to be close together, again the lock core lining be close together and spiral are put in sizeable lock tube, now two straightedges of spiral lean against lining outer ledge, its angle rib being close to lining can enter in working face corresponding recesses, it is face contact between lock core lining and spiral, just relative motion can not be had, 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 following main advantage:
Apparatus of the present invention can alleviate spiral wearing and tearing, need by other force-multiplier tool only object that just can realize Quick-clamped spiral hand-manipulated, and saving of work and time is economical reliable.
