Technical Field
The utility model relates to a shaft machining technical field, concretely relates to hydraulic chuck motor pivot processing frock floats.
Background
The fixture of the lathe mainly refers to a fixture arranged on a main shaft of the lathe, and the fixture is connected with the main shaft and drives a workpiece to rotate along with the main shaft. At present, lathe clamps mainly fall into two categories: various chucks are suitable for clamps for processing disc parts and short shaft parts; the clamp for centering, positioning and installing the workpiece in the center hole and the tip is suitable for shaft parts with larger length size or more processing procedures. In the prior art, when a solid shaft part such as a motor rotating shaft is machined, center holes are usually drilled on two end faces of the part, and then a tip is used for clamping the part through the center holes. Because the centre can not drive the solid shaft part to rotate, during processing, a heart-shaped chuck is firstly arranged on the shaft part, and then the heart-shaped chuck arranged on the shaft part is driven to rotate by a three-jaw chuck arranged on the main shaft, so that the rotation of the shaft part is realized. However, the method has some defects when the solid shaft parts are clamped: (1) the three-jaw chuck is clamped and fixed in a hand-twisting manner, so that the three-jaw chuck is very laborious to operate; (2) if the shaft parts are too long, the shaft parts are easy to deform and bend, and the cutter is easy to vibrate, so that cutter lines are generated, and machining errors are caused; (3) when the heart-shaped chuck is adopted, more parts are needed to be matched for use, the clamping process is troublesome, the assembling time is long, the consumed workload is large, and the processing efficiency is low.

And as optimization, a dustproof cover is fixed at the middle position of the top of the tray body. Therefore, the clearance between the chuck body and the soft clamping jaw is protected and shielded, and the problems of corrosion of the hydraulic chuck, jamming of transmission and the like caused by the fact that some scrap irons and cutting fluid enter the clearance in the machining process are solved.
Preferably, the dustproof cover is provided with a waterproof plug. Therefore, outside water and dust can be prevented from entering the hydraulic chuck, the hydraulic chuck is prevented from being wetted and rusted to be damaged, and the service life of the hydraulic chuck is prolonged. Furthermore, an annular groove is formed in the outer wall of the waterproof plug, and an O-shaped sealing ring is embedded in the annular groove and is tightly contacted with the dustproof cover. Set up O type sealing washer between shield and waterproof stopper, it is sealed effectual, can effectively prevent that water, dirt bits from soaking via the clearance between shield and the waterproof stopper, has further improved waterproof dustproof performance.
Preferably, the bottom of the soft jaw is provided with a first tooth portion, and correspondingly, the base jaw is provided with a second tooth portion matched with the first tooth portion on the surfaces of the two sides of the second sliding groove. When the soft jaw is mounted on the base jaw, the first tooth portion and the second tooth portion are engaged with each other to be in close contact, and at this time, the soft jaw is positioned with high accuracy in the radial direction with respect to the base jaw, and both are firmly connected.
Preferably, the number of the soft clamping jaws is three, and the included angle between every two adjacent soft clamping jaws is 120 degrees. At this moment, 3 soft claws just constitute triangle-shaped for it is more firm when centre gripping by the processing axle.
Preferably, the longitudinal section of the base claw is T-shaped. Thereby, the firm in connection nature between base claw and the first spout has been improved for the base claw is difficult for droing.
