Abstract
The utility model relates to a hydraulic clamping fixture for reinforcing bar pressure welding. The design scheme of the utility model is that the fixed clamping head of the clamping fixture is fixed on a clamping fixture body. A movable clamping head is fixed on a sliding barrel along the shaft line direction in the clamping fixture body. The fixed clamping head and the movable clamping head are composed of a clamping head seat, a wedge-shaped clamping block and a gear shaft. A shaft head is arranged on one end of the gear shaft. The shaft head is tightly connected with a section of cone body. A hole with the same taper is arranged in the clamping head seat. A screw rod is arranged on the other end of the gear shaft. An elastic element is arranged between a screw nut on the screw rod and the clamping head seat.
Description
The utility model relates to a kind of hydraulically operated fixture that steel bar gas connects that is used for.
It is to utilize the gas thermal-flame with reinforcing bar joint heating and melting that steel bar gas connects, and with hydraulic coupling end reinforced tight crimping is formed an integral body simultaneously, this moment two the upset force tons of between end reinforced.This just requires in course of exerting pressure anchor clamps reinforcing bar firmly can be clamped.Existing anchor clamps are quite heavy, and clamping and unclamping reinforcing bar all very wastes time and energy, and the butt joint reinforcing bar is difficult to centering, very easily skid when adding thermal weld, make the welding failure.Utility model patent CN87201765 " voussoir rack-and-pinion steel bar gas anchor clamps " adopts voussoir and rack-and-pinion device in chuck, simplified operation is time saving and energy saving in theory, but behind the wrench pretension, pretightning force can't keep, and reinforcing bar still can be shifted in slippage during the heating pressurization, is difficult to on-the-spot practical.
The purpose of this utility model is design a kind of energy reliable pretension, by further firm grip reinforcing bar, automatic centering of hydraulic coupling, and integral body is lightly, the steel bar gas of clamping connects hydraulically operated fixture in any direction.
Steel bar gas of the present utility model connects the hydraulically operated fixture design: the chuck of deciding of anchor clamps is fixed on the clamp body, moving chuck is fixed in the clamp body along on the slide cartridge of axis direction slippage, back-moving spring is housed in the slide cartridge, decides chuck and moving chuck and form by base of the carrier head, wedge-like clamp and gear shaft.The spindle nose of gear shaft one end for Gong turning, being right after spindle nose is one section cone, and one section hole that tapering is identical is arranged in the base of the carrier head, the two matches; The other end is a screw rod, between nut on the screw rod and the base of the carrier head flexible member is housed.
The utility model has the advantages that: 1. after clamping reinforcing bar in advance with wrench, two relative clamps can be clamped reinforcing bar reliably; 2. clamping force increases that be directly proportional with hydraulic coupling of when welding pressurization guarantees that butt joint is reliably successful; 3. but the reinforcing bar automatic centering of different-diameter; 4. clamping reinforcing bar in any direction clamps and gets loose rapidly, and is convenient and strength-saving; 5. anchor clamps are whole light and handy, are convenient to the job site and use.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 connects the vertical section schematic diagram of hydraulically operated fixture for the utility model steel bar gas;
Accompanying drawing 2 connects the schematic cross section of hydraulically operated fixture at the chuck place for the utility model steel bar gas;
Accompanying drawing 3 connects the vertical view of hydraulically operated fixture chuck for the utility model steel bar gas.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
As shown in Figure 1, decide chuck 2 on clamp body 1, moving chuck 3 is fixed on along on the slide cartridge 4 of axis direction slippage in the clamp body 1, and back-moving spring 5 is housed in the slide cartridge 4.Shown in Fig. 1,2 and 3, decide chuck 2 and moving chuck 3 and install along same axis, form by base of the carrier head 6, the two wedge-like clamps of installing relatively 7,8 and gear shaft 9. Clamp 7 and 8 is disymmetrical right-angled trapezium voussoir, and the acute angle angle is 8.5～13.5 degree, is installed in relatively in the base of the carrier head 6.The clamping face of clamp 7 is the flank of tooth or the shiny surface of V-type, and the V-type angle is 85 °～135 °, and the V-type bottom is excessive arc surface; The clamping face of clamp 8 is the plane that straight-tooth is arranged.Base of the carrier head 6 is the inclined ramp of equal angular with the mating surface of clamp 7,8, and this slideway is close on the inclined-plane of clamp 7,8, and along its slip.Limiting plate 10 is arranged at base of the carrier head 6 tops, and limiting plate 10 is curved down towards one side of clamp 7,8, is stuck in the top of clamp 7,8, is used for the location and the slide-and-guide of clamp 7,8.Surely all there is tooth bar the bottom surface of the clamp 7,8 of moving chuck, and the gear on this rack and pinion axle 9 is meshed.The spindle nose of one end of gear shaft 9 for Gong turning, being right after spindle nose is one section cone, and tapering is 1: 4～1: 10, and base of the carrier head 6 has the hole of one section identical tapering, and the two matches.There are two gears in the stage casing of gear shaft 9, the gear number of teeth 9～18, and modulus 1～3, the tooth bar with clamp 7,8 bottom surfaces is meshed respectively.Turning gear wheel shaft 9 moves on the direction that the limiting plate 10 of base of the carrier head 6 limits by gear and the moving clamp 7 of tooth bar subband and 8, thereby changes the distance between the two relative clamps.The other end of gear shaft 9 is a screw rod, and spiral or folded shape flexible member 11 are housed on it, and elastic force is 5～50N, compresses with nut 12.Adjusting nut 12 can be regulated the pretension elastic force of flexible member 11.
Two steel bar ends of butt joint place respectively to be decided between the relative clamp 7,8 of chuck 2 and moving chuck 3 two, turn gear shaft 9 with wrench, stir the tooth bar that is engaged with by the gear on the gear shaft 9, promptly drive clamp 7,8 and move, at the bottom of V-shaped groove, clamp reinforcing bar and make reinforcing bar centering.Produce frictional force because of flexible member 11 makes the taper seat between gear shaft 9 and the base of the carrier head 6 after the pretension, stop gear shaft 9 revolutions, keep clamp 7,8 firm grip reinforcing bars.During the pressurization welding, hydraulic coupling promotes slide cartridge 4 and drives moving chuck 3 and makes the reinforcing bar crimping, and when pressure further pushes base of the carrier head 6 with wedge- like clamp 7 and 8 during greater than pretightning force, clamp 7 and 8 just clamps reinforcing bar further securely, thereby avoid reinforcing bar skew slip when adding thermo-compressed, guarantee the crimping success.
