Abstract
The invention provides a three-jaw expansion floating pressure head, comprising a floating deviation correcting device, wherein the floating deviation correcting device comprises a supporting plate (6), balls (7), a bolt (8), rubber elastic rings (9), lower supporting seats (10), balls (11), an upper supporting seat (12) and a shaft (13). The invention has the following beneficial effects: in the pressing process, central deviation is automatically corrected through spherical surface contact of the rolling body and elastic deformation of the rubber elastic rings; the lower supporting seats (10) and a pressure head body (3) pass the pressing force; an electromagnet push rod (4) and three-jaw expansion supporting hooks (1) are installed in the pressure head body (3); and if the pressure head encounters end surfaces of blind holes or stepped holes, the three-jaw expansion supporting hooks (1) retract to avoid interference with the end surfaces of the holes during pressing. The pressure head can realize rapid grabbing and clamping of bearings or shaft sleeves and the bodies of the similar structure and realize pressing of the bearings or shaft sleeves on the blind holes, stepped holes, through holes, etc.
Description
Technical field
The present invention relates to a kind of for bearing or axle sleeve clamping and the three-jaw expansion floating pressure head that press-fits.
Background technology
Bearing or axle sleeve available pressure machine in assembling press-fits, also available mounting bush and hand hammer manual installation.Manual installation efficient is low, and labour intensity is large; Adopt forcing press to press-fit to have and be specifically designed to the pressure head that press-fits.Traditional pressure head can only realize press-fiting merely work, manually bearing or axle sleeve is positioned in the required housing dead eye that press-fits press-fiting middle need, is difficult to realize the automation assembling, and efficient is low, press-fits precision and is difficult to guarantee.
Although the appearance of clamping telescopic press head in the centre deviation self adaptation is arranged, but it is to utilize pressure head to be provided with crawl and the clamping of the body of back-up block and flexible slide block realization bearing or axle sleeve and similar structures, relatively waste material and process and assemble complicated structure because of it, do not have widely promotion and application.
Summary of the invention
The purpose of this invention is to provide a kind of three-jaw expansion floating pressure head that can realize bearing or axle sleeve clamping and press-fit usefulness, be installed on the forcing press and can realize the automation that bearing or axle sleeve press-fit, guarantee to press-fit precision high, press-fit steadily, efficient is high.
Technical scheme of the present invention is for this reason, three-jaw expansion floating pressure head, comprise the drift correction device that floats, the drift correction device that floats comprises supporting disk (6), ball one (7), screw (8), caoutchouc elasticity circle (9), lower bearing support (10), ball two (11), upper branching holder (12), upper branching holder (12) is connected as a single entity with connecting axle (13), also can be that lower bearing support (10) is connected as a single entity with connecting axle (13), it is characterized in that: be that supporting disk (6) has pressure head body (3), be provided with electromagnet push-rod (4) in the pressure head body (3), electromagnet push-rod (4) has three-jaw expansion hook (1), three-jaw expansion hook (1) is hinged on the inwall of pressure head body (3), and and the inwall of pressure head body (3) between be provided with spring (2).
Improvement to such scheme is: described pressure head body (3) is revolving body, and head becomes the surperficial body of the face of cylinder or taper seat structure.
Beneficial effect:
The present invention utilizes to float is equipped with the caoutchouc elasticity circle between upper branching holder described in the drift correction device and the lower bearing support, can utilize the sphere-contact of rolling element and caoutchouc elasticity circle strain automatically to revise deviation when press-fiting, and mainly play the guiding role; Electromagnet push-rod and three-jaw expansion hook are contained in the pressure head body; The three-jaw expansion hook can guarantee that pressure head realizes flexiblely when blind hole or shoulder hole press-fit, avoid press-fiting middle pressure head and hole end surface and interfere, and electromagnet push-rod is so that clamping is convenient, reliable, quick.
This pressure head adopts the characteristics of mechanism own and clamps the interior clamping that support force is realized bearing or axle sleeve in press-fiting process, automatically adapt to error between pressure head center and the center, hole by the drift correction device that floats, can realize the work that press-fits of the position bearings such as blind hole, shoulder hole, through hole or axle sleeve, simple in structure, press-fit steadily, be convenient to realize the automation that press-fits press-fit precision accurate, efficient is high.
