Abstract
The utility model relates to a hydraulic disk puller for claws positioned on the circumference of a connection body. The hydraulic disk puller comprises the connection body. The hydraulic disk puller is characterized in that a hydraulic device comprising an arm shaking mechanism, a plunger pump, a hydraulic cylinder and an oil storage chamber is arranged. The connection body is connected with the cylinder body of the hydraulic cylinder through threads. The utility model uses hydraulic propulsion replacing thread propulsion. The hydraulic disk puller has the advantages of handy operation, labor saving and time saving. In addition, no relative motion exists between a top shaft and the center hole of the shaft. Thus, the center hole of the shaft can not be damaged.
Description
The utility model is about hand tools, particularly about take off the driver chuck device of discoid part from axial workpiece.
Existing driver chuck device, its structure are that center band screw, a periphery are connected with the union body of 3-4 hook and are arranged in the screw mandrel of above-mentioned union body center screw.During use hook hooked the disk-shaped part that will choose around, the taper of screw mandrel or domed ends withstand in the centre bore of axle.Rotary screw, hook is done counter motion together with disk-shaped part and axle, thereby disk-shaped part is extracted from axle.Because disk-shaped part is an interference fit with axle, the axially loaded of screw mandrel is very big during work, add between upper screw rod and the centre bore and have relative motion, thus not only operation effort, the centre bore on the fragile again axle.
The purpose of this utility model be to provide a kind of operate light, can not damage the driver chuck device of the centre bore of axle again.
The purpose of this utility model is achieved in that a kind of hydraulic pressure driver chuck device that comprises union body, is positioned at the hook of union body periphery, it is characterized in that being provided with the hydraulic means that comprises crank handle mechanism, plunger displacement pump, fluid power cylinder and reservoir compartment; Union body links to each other with the cylinder body of fluid power cylinder with screw thread.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
The utility model comprises hook 7, union body 12 and hydraulic means as shown in drawings.Described hydraulic means comprises the hydraulic means of crank handle mechanism, plunger displacement pump 17, fluid power cylinder 10 and reservoir compartment 6.Crank handle mechanism comprises handle 1, handle set 3, rocking bar 4 and rocking bar core 5.Handle 1 inserts in the hole of handle set 3 with the one end.Handle set 3 usefulness bearing pins 2 are hinged with plunger one end of plunger displacement pump 17.Rocking bar core 5 is arranged on the housing of plunger displacement pump 17.Rocking bar 4 two ends are hinged on respectively on handle set 3 and the rocking bar core 5.Plunger displacement pump 17 is fixed on the shell 15.Be provided with the reservoir compartment 6 that constitutes by leather bag 16 in the shell 15.Plunger displacement pump 17 by valve respectively with the oil circuit that communicates with fluid power cylinder 10 and reservoir compartment 6.Also be provided with the oil return valve that comprises oil return screw 13 on the shell 15.Be provided with return spring 9, piston 14 and apical axis 8 in the cylinder body of fluid power cylinder 10.Apical axis 8 one ends link to each other with piston 14, and the other end stretches out in outside the fluid power cylinder 10.The above-mentioned apical axis end that stretches out in fluid power cylinder 10 is cone or hemisphere.Union body 12 usefulness thread connection can be regulated the position of union body 12 on fluid power cylinder 10 arbitrarily in the cylinder body outside of fluid power cylinder 10.Hook 7 is no less than 3, and they are hinged on the union body 12 with connecting rod 11 respectively.The cylinder body of fluid power cylinder 10 is fixed on the shell 15; It also can be the part of shell 15.During work hook 7 is hooked the outer rim of disk-shaped part, the taper or the spheric end that apical axis 8 are stretched out fluid power cylinder 10 withstand in the centre bore of axle.Shake handle 1, plunger displacement pump 17 is gone into fluid power cylinder 10 with oil pressure, promote piston 13 with the direction motion of apical axis, just make fluid power cylinder 10 do counter motion with axle, till disk-shaped part takes off from axle together with the disk-shaped part on union body 12, hook 7 and the axle to axle.Extract handle 1, use wrench on it to turn the oil return screw 13 of oil return valve, under the effect of return spring 9, the oil in the fluid power cylinder 10 return reservoir compartment 6 through oil return valve, and apical axis 8 is also return with piston 14 in the cylinder body of fluid power cylinder 10, recovers initial state.
The utility model uses hydraulic pressure to advance to replace screw thread to advance, not only operate light, laborsaving, save time.And, can not damage the centre bore of axle owing to no relative motion between the centre bore of apical axis and axle exists.Not the time spent, handle can be taken off, reduced volume is convenient for carrying and collects.
