The specific embodiment
As shown in figures 1 and 3, the bearing press-in device of the present invention's design comprises anchor clamps and pressure head.Anchor clamps comprise upper substrate 4, infrabasal plate 7 and ball 6; Ball 6 places by ball retainer 5, between the infrabasal plate, one side of infrabasal plate 7 is equipped with keeper 9, one end of this keeper 9 is fixed on the infrabasal plate by rotating shaft 13 and screw 8, the end face of the other end and upper substrate are on same plane, the relative opposite side of infrabasal plate is equipped with clamping element 3, one end of this clamping element is fixed on the infrabasal plate by rotating shaft 10 and screw 2, the end face of the other end and upper substrate are on same plane, fixed block 11 is equipped with in the 3rd side centre of infrabasal plate, elastic plate 12 is housed on the upper substrate of homonymy, one end of elastic plate and fixed block relative fixed, upper substrate is provided with telltale mark 24.Pressure head comprises coupling bar 15, gland 20, guide pin bushing 19 and spring 18, guide pin bushing is in the outside of gland, coupling bar 15 and gland 20 coaxial installations, the end of gland is coaxially installed with the back of the body female 16 and adjusts cover 17, spring 18 radially places the outside of gland, that is between guide pin bushing 19 and the adjustment cover 17, the guide pin bushing end is uniformly distributed with jaw 22 along the circumference, one end of jaw 22 is fixed on by screw 21 on the outer wall of guide pin bushing end, and the other end becomes U-shaped to stretch to the center of circle.
The course of work of the bearing press-in device of the present invention's design is as follows:
Anchor clamps interface 1 is connected with machining center workbench T type groove by bolt, and the workpiece that need be pressed into bearing is fixed on the upper substrate 4.When the processing operation, keeper 9 tightens screw 8 by keeper and tightens on infrabasal plate 7, and upper substrate 4 is played the role of positioning; Clamping element 3 tightens being connected 4 clamping actions of upper substrate of screw 2 and infrabasal plate 7 by clamping element, because keeper 9 and clamping element 3 are to fit along vertical low-angle inclined-plane at the faying face place with upper substrate 4, when clamping, can produce downward power to upper substrate 4, make upper substrate 4 can be pressed on the ball 6 securely, keeper 9 and clamping element 3 and upper substrate 4 have the inclined-plane that cooperates along side direction simultaneously, can guarantee upper substrate accurate location in the horizontal direction; When assembling work, keeper tightens screw 8 and clamping element and tightens screw 2 and unclamp, and keeper 9 and clamping element 3 disengage with upper substrate 4, and upper substrate 4 floats on the ball 6, is in submissive state, and submissive rigidity depends on the rigidity of elastic plate 12.
Grabbing of structure middle (center) bearing at pressure head takes three jaws 22 that distribute along circumference 120 degree of dependence to finish.Being pressed into by coupling bar 15, gland 20 of bearing finished, and guide pin bushing 19 play the guiding role in process of press in.
