Embodiment Construction
[0014] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0015] Such as image 3 As shown, it includes chuck body 1, front end cover 2, loosening plate 3, three sliding seats 4, three claws 5, three wedges 6, flange 7, nine sets of disc spring mechanisms 8, cylinder base 9, ten small oil cylinder blocks 10, ten small oil cylinder heads 11, ten small oil cylinder pistons 12, ten springs 13, etc.
[0016] The invention consists of two parts: a chuck and an oil cylinder; the chuck part is installed on the head of the main shaft, and the oil cylinder part is installed on the bedside box.
[0017] The chuck part is composed of chuck body 1, front end cover 2, release plate 3, three sliding seats 4, three claws 5, three wedge blocks 6, flange plate 7 and nine sets of disc spring mechanisms 8 The main body of the chuck; the flange 7 is passed through the penetrating screw on the chuck body 1, and is fixedly conne...

The invention relates to a friction welding power chuck with power supplied by springs. The friction welding power chuck comprises the chuck and an oil cylinder. Part of the chuck is arranged on the head portion of a spindle, and part of the oil cylinder is arranged on a headstock. A chuck main body is composed of a chuck body, a front end cover, a loosening chuck, three sliding seats, three clamping jaws, three tapered wedge blocks, a flange plate and nine sets of disc spring mechanisms. The oil cylinder is composed of an oil cylinder base and ten oil cylinder parts. The ten oil cylinder parts are all evenly arranged on the oil cylinder base and are all evenly connected with the oil cylinder base. The ten oil cylinder parts comprise ten oil cylinder bodies, ten oil cylinder heads, ten oil cylinder pistons and ten springs. The friction welding power chuck with the power supplied by the springs is simple and compact in structure and reasonable; the power supplied by a spring mechanism is large, the clamping force of the chuck is large, and the torque is large; under the high-temperature state, due to the fact that oil cylinder is not in contact with a machined workpiece, temperature rising does not need to be considered, the service life is long, and the friction welding chuck is particularly suitable for being matched with friction welding equipment.
Description
technical field [0001] The invention relates to a power chuck for friction welding with power provided by a spring, which is used for matching with a numerical control lathe and belongs to the technical field of machine tool accessories. Background technique [0002] In the prior art, a commonly used power chuck is powered by a hydraulic or pneumatic system to realize clamping and loosening of the chuck. During the process of clamping (tightening) the workpiece by the chuck, the power source must provide power at all times, otherwise the workpiece will fly out during high-speed rotation, causing great harm. Therefore, the power source must have its own or an external pressure-holding mechanism to achieve the purpose of providing constant power. Contents of the invention [0003] The invention provides a chuck with its own spring power source to realize clamping, and an external supporting hydraulic system to provide a loosening thrust, which is mostly used in the power ch...
