The working principle is as follows: when the device is used, firstly, the device is flatly placed on a table top, so that the clamping parts are over, a workpiece to be processed is placed in the center between the clamping parts, then, the sharp ends of 4 external oil pipes are inserted into the rubber plug 11, at the moment, the first adjusting wheel 7 is pressed and rotated, so that the first adjusting wheel 7 is forced to extrude the second spring 35 below the first adjusting wheel and push the sliding block 36 to slide in the sliding cavity 37, the first adjusting wheel 7 rotates to be meshed with the first fluted disc 28, at the moment, the 4 fixed claws 1 and the clamping parts continuously move towards the central point of the first fluted disc 28 along with the rotation of the spiral fluted disc-shaped gullets of the first fluted disc 28, when the pressure head 4 is contacted with the surface of the workpiece, the pressure rod 5 and the piston plate 17 are driven by the resistance given by the workpiece to stop advancing, the oil tank 2 continuously moves along with the fixed claws 1, therefore, the piston plate 17 extrudes the hydraulic oil in the auxiliary oil cavity 16 into the main oil, the oil outlet 15 at one end of the main oil cavity 13 is extruded into the external oil pipe, so that the phenomenon that the workpiece is slightly displaced due to the thrust of the pressure head 4 when the pressure head 4 is in contact with the curved surface workpiece is effectively avoided, the pressure head is stopped after all the pressure heads 4 are in contact with the workpiece and the corresponding pressure rods 5 are pressed into the auxiliary oil cavities 16, hydraulic oil is slightly injected into the main oil cavity 13 and the auxiliary oil cavities 16 through an oil pump connected with one end of the external oil pipe, so that the injected hydraulic oil pushes the pressure rods 5 and the pressure heads 4 to press against the surface of the workpiece, the pressure head 4 can extrude and deform the spring I19 according to the curve radian of the surface of the workpiece in the pressing process, and the pressure head 4 and the ball head 18 slightly rotate, so that the pressure head 4 better presses against the workpiece to fix the workpiece, the purpose of clamping an irregular workpiece with a complex curved surface by the device is realized, and the V-shaped groove and the rubber sheet arranged, the hard extrusion of the pressing head 4 to the workpiece can be effectively reduced, the surface of the workpiece is prevented from being damaged, the attractiveness of the workpiece is ensured, and after clamping is completed, corresponding fixing parts can be selected for connection according to a machine tool to be machined; when the device is connected with a cylindrical fixed hole groove such as a lathe and the like, the second adjusting wheel 8 is pressed and rotated, so that the second adjusting wheel 8 is forced to extrude the second spring 35 below the second adjusting wheel and push the sliding block 36 to slide in the sliding cavity 37, the second toothed disc 31 is conveniently rotated through the rotation of the second adjusting wheel 8, the second toothed disc 31 is further rotated, the clamping seat 23 is pushed to slide out from the first accommodating cavity 30, the device is convenient to be assembled with the lathe through the extended clamping seat 23, when the device is connected with a strip-shaped fixed hole groove such as a milling machine, a planer and the like, the third adjusting wheel 9 is pressed and rotated, so that the third adjusting wheel 9 is forced to extrude the second spring 35 below the third adjusting wheel and push the sliding block 36 to slide in the sliding cavity 37, the first adjusting wheel 9 is meshed with the first gear 38 to drive the fixed rod 39 and the third gear 41 to rotate and mesh, and the second gear 40 and the screw 21 of, make and remove seat 20 and drive fixed strip 6 and slide rail 26 by accomodating the inside roll-off in chamber two 33 and accomodating chamber three 34 under the effort of screw rod 21 and slide bar 24, again according to treating the interval between the bar fixed orifices groove of clamping lathe, adjust 2 positions of fixed strip 6 on corresponding slide rail 26, so that the device through the fixed strip 6 that stretches out realize with the milling machine that has different interval bar fixed orifices grooves, the planer assembly, the suitability of device has been improved, the different link of device can be flexible simultaneously and accomodate, the whole volume of device has effectively been reduced, be convenient for accomodate and use of device.
