Abstract
The utility model discloses a plasma arc surface hardening work piece clamping and rotating device, which comprises a bearing seat and a rotating shaft, wherein, one shaft end of the rotating shaft is connected with a three-jaw chuck through a three-jaw connecting flange, and a transmission gear, a gear connecting sleeve are mounted at the other shaft end of the rotating shaft; the transmission gear is connected with the gear connecting sleeve connected with the rotating shaft; an insulating cushion is arranged between the transmission gear and the gear connecting sleeve; an insulating sleeve is arranged between the inner hole surface of the transmission gear and the rotating shaft; and insulating washers are respectively arranged between the transmission gear and a corresponding nut on a connecting screw rod and between the gear connecting sleeve and a corresponding nut on the connecting screw rod. The plasma arc surface hardening work piece clamping and rotating device can guarantee the safety of system equipment, can conveniently clamp work pieces, is easy to center and replace, is convenient to detach, and is suitable for changes of sizes of the work pieces, so that the application range of the plasma arc surface hardening work piece clamping and rotating device is greatly expanded.
Description
Technical field
The utility model relates to plasma quenching device field, is specially a kind of plasma arc surface hardening workpiece and clamps swivel arrangement.
Background technology
Quenching is a kind of steel part is heated to austenitizing temperature and keeps certain hour, then with greater than the critical cooling velocity cooling, to obtain the thermal treatment process of non-diffusion-type transition tissue.Quenching has a variety of methods, and wherein relatively commonly used have a plasma quenching.Plasma quenching need use gripping unit to clamp and rotational workpieces, and the gripping unit parts for maintenance of prior art is very inconvenient with replacing, and is prone to leaky at workpiece surface.
The utility model content
The purpose of the utility model provides a kind of plasma arc surface hardening workpiece and clamps swivel arrangement, and is inconvenient to solve the maintenance of prior art gripping unit, is prone to the problem of electric leakage.
In order to achieve the above object, the technical scheme that the utility model adopted is:
The plasma arc surface hardening workpiece clamps swivel arrangement; Include chock and be rotatably installed in the turning axle in the chock; It is characterized in that: axle head of said turning axle is connected with thread jaw chuck through the three-jaw joint flange; Another axle head of turning axle is equipped with transmitting gear, gear joint sleeve; Said transmitting gear is connected with the gear joint sleeve through connecting screw rod, and through being screwed on the nut locking on connecting screw rod two rod ends, said gear joint sleeve is connected with turning axle through coupling screw.
Described plasma arc surface hardening workpiece clamps swivel arrangement; It is characterized in that: be provided with the insulating mat that is enclosed within on the corresponding axle head of turning axle between said transmitting gear end face and the gear joint sleeve end face; Be provided with the insulation covering that is enclosed within on the corresponding axle head of turning axle between the corresponding axle head outer wall of said transmitting gear inner hole surface, be respectively arranged with insulating washer between the nut on said transmitting gear, gear joint sleeve and the corresponding separately rod end of connecting screw rod with turning axle.
In the utility model; The end face of transmitting gear, endoporus are connected with turning axle with the gear joint sleeve with insulation covering through insulating mat; Nut is connected with the gear joint sleeve with transmitting gear through insulating washer simultaneously, when guaranteeing the plasma arc surface hardening workpiece, though workpiece is through very big electric current; But propulsion source has no effect to external world, guarantees system device safety.The plasma arc surface hardening workpiece adopts thread jaw chuck to clamp, and it is convenient to clamp, and centering is easy.Thread jaw chuck is connected with axle through the three-jaw joint flange, and convenient disassembly is changed easily, adapts to the variation of workpiece size, has greatly expanded the range of application of the utility model.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.The utility model comprises connecting screw rod 1, nut 2, plain washer 3, insulating washer 4, insulation covering 5, insulating mat 6, transmitting gear 7, gear joint sleeve 8, coupling screw 9, left shaft holder 10, turning axle 11, right bearing seat 12, three-jaw joint flange 13, thread jaw chuck 14.Turning axle 11 is rotatably installed in the left and right chock 10,12; Transmitting gear 7 is connected with gear joint sleeve 8 through connecting screw rod 1; Gear joint sleeve 8 is connected with turning axle 11 through coupling screw 9, and thread jaw chuck 14 also is connected with turning axle 11 through three-jaw joint flange 13, and the plasma arc surface hardening workpiece clamps with thread jaw chuck 14; When transmitting gear 7 during, drive the Workpiece Rotating that thread jaw chucks 14 clamp like this through turning axle 11 in the external power source driven rotary.The end face of transmitting gear 7 is through insulation between insulating mat 6 and the gear joint sleeve 8 in the utility model; The endoporus of transmitting gear 7 is connected with turning axle 11 through insulation covering 5; Nut 2 is through insulation between insulating washer 4 and transmitting gear 7, the gear joint sleeve 8, therefore when the plasma arc surface hardening workpiece, though workpiece passes through very big electric current; But propulsion source has no effect to external world, guarantees system device safety.The plasma arc surface hardening workpiece adopts thread jaw chuck 14 to clamp, and it is convenient to clamp, and centering is easy.Thread jaw chuck 14 is connected with axle through three-jaw joint flange 13, and convenient disassembly is changed easily, when the workpiece size variation, need only change thread jaw chuck 14 and just can work with three-jaw joint flange 13, has greatly expanded the range of application of this clamping swivel arrangement.
