The utility model has the advantages that: the utility model adopts the inner bearing type location structure under cylinder action.Outside the utility model decapacitation is enhanced productivity greatly, be intended to solve positioning precision problem, reach high-precision positioning requirements, realize perfect weldquality.Can realize the positioning requirements that caliber differs many various workpieces within the specific limits simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment: inner bearing type positioning clamping fixture as shown in Figure 1, comprise mold body 18, the left end internal thread of described mold body 18 is connected with output shaft 2, is provided with main shaft inner sleeve 17 in output shaft 2, and main shaft inner sleeve 17 right parts are provided with circlip 4.In main shaft inner sleeve 17, be provided with air cylinder connecting rod 1, between air cylinder connecting rod 1 and main shaft inner sleeve, be provided with axle sleeve 22.The right-hand member that is positioned at air cylinder connecting rod 1 is provided with primary nut 5 and adjusting nut 6 successively, and adjusting nut 6 is connected with expansion link 3 by set screw 19.At expansion link 3 front ends, be provided with buffer spring 7, the right-hand member of expansion link 3 is established coupled connecting rod 8, connecting rod 8 right-hand members are provided with expander roll 12, described expander roll 12 is positioned at mold body 18, described connecting rod 8 is arranged in the shrinkage pool 21 of expander roll 12 left ends, between connecting rod 8 and shrinkage pool 21 inwalls, be provided with thrust bearing 9 and rolling bearing 10, between described expander roll 12 and mold body 18, be provided with coil tension spring 11.Centered by the right part of described connecting rod 8, with the little axle of step of detent, described thrust bearing 9 and rolling bearing 10 are positioned on the little axle of step, between thrust bearing 9 and rolling bearing 10, are provided with back-up ring 20.Described expander roll 12 right part is conical, at the right-hand member of mold body 18, is radially provided with the symmetrical square hole in position 15, is provided with expansion block 13 in square hole 15, is provided with back-moving spring 14 in expansion block 13.The quantity of described square hole 15 is at least three.The right-hand member of described expander roll 12 is provided with for holding the pressure pin 16 of expansion block 13.The shape of the bottom surface of above-mentioned expansion block 13 matches with expander roll 12 right-hand member conical inclined surface.
During work, the utlity model has location and revolute function:
1, positioning function: manual or solenoid control cylinder action, making cylinder promote air cylinder connecting rod 1 travels forward, air cylinder connecting rod 1 puts on thrust on expander roll 12 by a secondary thrust bearing 9 and rolling bearing 10 by expansion link 3, adjusting nut 6, expander roll 12 advances, expansion block 13 is radially moved, will be installed on the body swelling location of [W1] on mold body 18.[W2]?。
2, revolute function: for the welder of institute part, if weld seam is annular, be generally workpiece rotation, welding gun is motionless.But during workpiece rotation, can not allow again location rotate with the piston rod of cylinder, for realizing this function, positioner structure design principle is as follows: mold body 18 is connected by the output shaft 2 of thread connection and main spindle box, the thrust of cylinder is under the acting in conjunction of a secondary thrust bearing 9 and rolling bearing 10, make the thrust of axis direction with non-interference around the rotation of axis direction, in the time of can guaranteeing to rotate, the thrust of cylinder be along the location of the unchanged realization of axis [W3] body, if cylinder rod and then rotates and certainly will cause wearing and tearing while can solve again rotation, shorten the problems such as cylinder life-span.
By above two kinds of principle designs, can reach the location of tubular workpiece, realize spinfunction simultaneously.
