Adopt the dual regulation clamping device of technical solution of the present invention, comprise positioning tube, positioning tube is arranged on machine tool chief axis, the right-hand end of positioning tube is hinged with at least two clamps, clamp is for clamping push rod, thus clamping work pieces, at least two clamps be positioned at center, positioning tube end for the center of circle circumferentially, thus workpiece can be positioned by its center line, the outer wall of positioning tube is arranged with clamping cylinder, clamping cylinder is used for compressing clamp from outside, realize the location to compact heap, avoid compact heap outwards movement, clamping cylinder is threaded with positioning tube, thus positioning tube can carry out spacing to clamping cylinder, clamping cylinder is avoided to move to the left under the pressure of clamp, sleeve is provided with in positioning tube, sleeve is used for positioning frustum, the outer wall of sleeve and the endoporus contact internal walls of positioning tube, thus sleeve can slide in the endoporus of positioning tube, and can ensure that the center line of sleeve and the center line of positioning tube are located along the same line, and then ensure that workpiece is located with its center line, frustum is pruned by circular cone and to be formed behind top, frustum is used for being held out against by clamp from inner side, thus coordinate clamping cylinder to position clamp together, the outer wall of frustum and the inner side of clamp offset, thus the transverse shifting of frustum can make clamp radially move, pull bar is provided with in sleeve, pull bar is used for workpiece cover location, the outer wall of pull bar and the endoporus contact internal walls of sleeve, thus pull bar can slide in hub internal bore, and can ensure that the center line of pull bar and the center line of positioning tube are located along the same line, and then ensure that workpiece is located with its center line, the sidewall of workpiece cover is provided with one group of push rod, workpiece is positioned at workpiece cover, the medial end of push rod and the outer wall of workpiece offset, outboard end and the clamp of push rod offset, thus can workpiece pressing, one group of push rod is uniformly distributed circumferentially on workpiece cover sidewall, thus workpiece stress equalization can be made.
Technique effect of the present invention is: be connected because push rod and workpiece overlap side walls, and pull bar can slide in sleeve, therefore pulls pull bar to clamp the workpiece of different size by left and right; Due to clamp and positioning tube hinged, clamping cylinder is threaded with positioning tube, and sleeve can slide in positioning tube endoporus, therefore by moving left and right sleeve and clamping cylinder to change the angle of inclination of clamp, thus the workpiece of clamping different size scope.Because the present invention can clamp the workpiece of different size in same size range when implementing, and can also clamp the workpiece of different size scope, achieve dual regulation, adjustable range is large, and the size range getting final product clamping work pieces is large.
Further, the medial end of described push rod is provided with arc clamping head, and arc clamping head and workpiece outer wall offset.Arc clamping head and workpiece outer wall offset and the clamping effect of push rod to workpiece can be made better.
Further, the outboard end of described push rod is provided with roller, offsets inside roller and clamp.Roller can reduce the frictional force between push rod and clamp, push rod is slided on the inner surface of clamp easier.
Further, be provided with chute inside described clamp, roller is positioned at chute.Chute can make roller more stably slide inside clamp, avoids roller and clamp to skid.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is further illustrated:
Fig. 1 is the schematic diagram of dual regulation clamping device embodiment of the present invention;
Fig. 2 is the schematic diagram of push rod.
Detailed description of the invention
Wherein: pull bar 1, sleeve 2, clamping cylinder 3, positioning tube 4, frustum 5, push rod 6, workpiece cover 7, workpiece 8, locking nut 9, clamp 10, arc clamping head 11.
As shown in Figure 1, dual regulation clamping device of the present invention, comprise positioning tube 4, positioning tube 4 is laterally placed, the right-hand end of positioning tube 4 is hinged with four clamps 10, four clamps 10 be uniformly distributed in center, positioning tube 4 end for the center of circle circumferentially, the inner side of four clamps 10 is equipped with axial chute, the outer wall of positioning tube 4 is arranged with clamping cylinder 3, clamping cylinder 3 is threaded with positioning tube 4, the length of clamping cylinder 3 is longer than the length of positioning tube 4, all offsets outside the right-hand end of clamping cylinder 3 and four clamps 10; Sleeve 2 is provided with in positioning tube 4, the outer wall of sleeve 2 and the endoporus contact internal walls of positioning tube 4, sleeve 2 can be slided in positioning tube 4 endoporus, the right side of sleeve 2 is arranged with frustum 5, frustum 5 comprises bigger diameter end and miner diameter end, and the miner diameter end of frustum 5 is towards a left side, and the outer wall of frustum 5 and the inner side of clamp 10 offset, left end place sleeve 2 being positioned at positioning tube 4 is also provided with locking nut 9, and locking nut 9 is for locking sleeve 2; Pull bar 1 is provided with in sleeve 2, the outer wall of pull bar 1 and the endoporus contact internal walls of sleeve 2, pull bar 1 is slided in the endoporus of sleeve 2, the right-hand end of pull bar 1 is fixedly connected with workpiece 8 and overlaps 7, the sidewall that workpiece 8 overlaps 7 is provided with four push rods 6, four push rods 6 overlap on 7 sidewalls in workpiece 8 and are uniformly distributed circumferentially, push rod 6 and workpiece 8 overlap 7 side walls and are connected, the outboard end of push rod 6 is provided with roller, chute on roller and clamp 10 offsets, the inner side of push rod 6 is provided with arc clamping head 11, and as shown in Figure 2, arc clamping head 11 and workpiece 8 outer wall offset.
In specific implementation process, pushing drawing rod 1 to the right, is put in columnar workpiece 8 between four push rods 6, pulls pull bar 1 left, and the roller of push rod 6 outboard end is moved to the left along chute, until workpiece 8 clamps by the arc clamping head 11 on push rod 6.When workpiece 8 size is larger, unscrew locking nut 9, be moved to the left sleeve 2 and clamping cylinder 3 simultaneously, the gradient of clamp 10 is increased, thus the workpiece 8 of large-size can be clamped, then use locking nut 9 locking sleeve 2; When workpiece 8 size is less, unscrew locking nut 9, move right sleeve 2 and clamping cylinder 3 simultaneously, the gradient of clamp 10 reduced, thus can clamp the workpiece 8 of reduced size.
