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

The flexible pressure head that floats of three-jaw
Technical field
The present invention relates to the flexible pressure head that floats of a kind of three-jaw that is used for bearing or axle sleeve clamping and 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 big; Adopt forcing press to press-fit to need and be specifically designed to the pressure head that press-fits.Traditional pressure head can only be realized press-fiting work merely, needs manually bearing or axle sleeve to be positioned in the required housing dead eye that press-fits in press-fiting, and is difficult to realize the automation assembling, and efficient is low, press-fits precision and is difficult to guarantee.
Though the appearance of the flexible pressure head of clamping in the centre deviation self adaptation is arranged, but it is to utilize pressure head to be provided with the extracting and the clamping of the body of back-up block and flexible slide block realization bearing or axle sleeve and similar structures, because of it compares waste material and process and assemble structure more complicated, there are not promotion and application widely.
Summary of the invention
The purpose of this invention is to provide a kind of flexible pressure head that floats of three-jaw 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 the precision height, press-fit steadily the efficient height.
Technical scheme of the present invention for this reason is, the flexible pressure head that floats of three-jaw, comprise the drift correction device that floats, the drift correction device that floats comprises supporting disk (6), ball (7), screw (8), caoutchouc elasticity circle (9), lower support seat (10), ball (11), upper branching holder (12), upper branching holder (12) is connected as a single entity with axle (13), also can be that lower support seat (10) is connected as a single entity with 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 the flexible hook (1) of three-jaw, the three-jaw hook (1) that stretches 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 a revolving body, and head becomes the surperficial body of the face of cylinder or taper seat and similar structures.
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 support seat, can utilize the sphere contact and the caoutchouc elasticity circle strain of rolling element to revise deviation automatically when press-fiting, and mainly play the guiding role; The flexible hook of electromagnet push-rod and three-jaw is contained in the pressure head body; The flexible hook of three-jaw can guarantee that pressure head realizes flexiblely when blind hole or shoulder hole press-fit, pressure head and hole end surface interfere in avoiding press-fiting, and electromagnet push-rod makes clamping 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 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, it is accurate to press-fit precision, the efficient height.
Description of drawings

The A-A cross-sectional view of the flexible pressure head that floats of Fig. 2 three-jaw.
The 1st, the three-jaw hook that stretches, the 2nd, spring, the 3rd, pressure head body, the 4th, electromagnet push-rod, the 5th, bearing, the 6th, supporting disk, the 7th, ball, the 8th, screw, the 9th, caoutchouc elasticity circle, the 10th, lower support seat, the 11st, ball, the 12nd, upper branching holder, the 13rd, axle.
The specific embodiment
As Fig. 1, shown in Figure 2, the flexible pressure head that floats of three-jaw mainly is made up of the flexible hook device of three-jaw and unsteady drift correction device two parts.The flexible hook device of three-jaw is made up of the flexible hook 1 of three-jaw, spring 2, pressure head body 3, electromagnet push-rod 4; The drift correction device that floats is made up of supporting disk 6, ball 7, screw 8, caoutchouc elasticity circle 9, lower support seat 10, ball 11, upper branching holder 12.
Upper branching holder 12 is connected as a single entity with axle 13, also can be that lower support seat 10 is connected as a single entity with axle 13, between upper branching holder 12 and the lower support seat 10 rolling element ball 11 is housed, between lower support seat 10 and the supporting disk 6 rolling element ball 7 is housed, between lower support seat 10 and the upper branching holder 12 caoutchouc elasticity circle 9 is housed, when press-fiting, can utilizes the sphere contact and the caoutchouc elasticity circle strain of rolling element to revise centre deviation automatically; Press-fit lower support seat 10 and pressure head body 3 transmission pressure assembling forces in the process; The flexible hook 1 of electromagnet push-rod 4 and three-jaw is contained in pressure head body 3 inside, and in press-fiting process, pressure head is as blind hole or shoulder hole end face, and flexible hook 1 withdrawal of three-jaw is avoided press-fiting middle hook and hole end surface and interfered; When press-fiting, the body of bearing 5 or axle sleeve and similar structures is enclosed within on the pressure head body 3, the head of pressure head body is made into the surperficial body that bearing or axle sleeve and similar structures will cooperate, and this surface body plays the guide-localization effect.Press-fit in the process, pressure head is connected on the forcing press, drives pressure head and returns at the used back forcing press that down bearing or axle sleeve is press fit in the dead eye of press pressure, and pressure head withdraws from from the bearing that press-fited or axle sleeve, finishes to this once to press-fit process.Continue to press-fit and to enter next circulation.
