Abstract
The utility model discloses a self-centering structure capable of automatically retracting. The self-centering structure comprises a taper pin, a positioning block, a screw rod and a cover plate. The taper pin is installed in an inner groove of a pushing component and is provided with a cone-shaped head part. The positioning block is provided with a pushing component installation groove and a cone-shaped taper pin installation groove, steel ball moving channels provided with steel balls are symmetrically arranged on the side wall of the taper pin installation groove, guiding blocks are installed at one ends, far away from the taper pin installation groove, of the steel ball moving channels, each guiding block is provided with a lifting pin assembling hole communicated with the steel ball moving channels, the lifting pin assembling holes and the steel ball moving channels are respectively provided with a lifting pin, and a spring is placed on each lifting pin in a sleeved mode. The screw rod is installed on the taper pin head, the tail part of the screw rod is placed in a screw rod groove in the positioning block, and the bottom of the screw rod groove is communicated with the top of the cone-shaped taper pin installation groove. The cover plate is placed on the tail part of the screw rod in a circumferential mode. When lifting, the taper pin drives the steel balls to move outwards, the lifting pin is enabled to extend outwards, and a self-centering role is played. When the taper pin moves reversely, the lifting pin and the steel balls are retracted to an original position at the same time. The whole process is not interfered by any factors in the outer world, the whole structure is simple, and the self-centering structure is easy to machine.
Description
Technical field
The utility model relates to a kind of self-centering structure of automatically retractable.
Background technology
Automatically core structure use in the anchor clamps field more, but existing self-centering structure complex structure often, and can't realize flexible automatically.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of self-centering structure of automatically retractable is provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of self-centering structure of automatically retractable is characterized in that having:
One is installed on the taper pin of push mechanism inner groovy, and it has the head of a taper;
A positioning block, the taper taper pin mounting groove that it has the push mechanism mounting groove and mates with the taper pin front end, the sidewall symmetric arrangement of described taper pin mounting groove has the steel ball moving conduit that steel ball is installed, described steel ball moving conduit taper pin mounting groove far away end is equipped with guide block, described guide block has the ejector pin pilot hole that communicates with the steel ball moving conduit, described ejector pin pilot hole and steel ball moving conduit are provided with the ejector pin of sheathed spring, and this ejector pin steel ball end far away can stretch out from the ejector pin pilot hole;
Be installed on the screw rod of taper pin head, its afterbody is located at the screw slot that locating piece arranges, this screw slot bottom communicate with the top of taper taper pin mounting groove and Zhou Jing greater than the Zhou Jing at the top of taper pin mounting groove;
Cover plate, it circumferentially is located at the afterbody of screw rod and is covered on the screw slot top.
Described steel ball moving conduit is consistent with the diameter of steel ball near the diameter of taper pin mounting groove one end.
The beneficial effects of the utility model are: drive steel ball when taper pin rises and outwards move, make ejector pin protruding, realize Self-centering Action; When taper pin moves in the other direction, then ejector pin and steel ball bounce back to original position simultaneously, and whole process is not disturbed by extraneous any factor, and total is simple, is convenient to processing.
Description of drawings
Fig. 1 is a kind of self-centering structure structural representation of automatically retractable.
The specific embodiment
