Abstract
The utility model relates to a holding device. A holding device of the prior art is difficult in processing and can not be located freely. A conical mounting hole is arranged inside a rotary component of the holding device; an elastic rising sleeve takes the shape of a cone corresponding to the shape of the mounting hole; a telescopic chute is arranged on the elastic rising sleeve along the axial direction; the elastic rising sleeve is sleeved outside a rotary shaft; the rotary component is sleeved outside the elastic rising sleeve; a guide groove is arranged on the sidewall of the mounting hole; a holding groove is arranged on the external sidewall of the elastic rising sleeve; holding screws are arranged inside the guide groove and the holding groove and in threaded connection with the holding groove. The rotary component is pressed down through the holding screws, and the elastic rising sleeve holds the rotary component and the rotary shaft simultaneously, thereby holding of the rotary component and the rotary shaft can be realized. The utility model has the advantages of relatively simple structure, low manufacturing cost, convenient assembly, and capability of realizing free locating.
Description
Technical field
The utility model belongs to mechanical field, relates to a kind of mechanical tightening parts, specifically is a kind of parts and a tightening device that positions and make parts to rotate together with the axis.
Background technique
The tightening device is a kind of that rotary component is fixing with axle, make that rotary component can be rotated under the transmission of axle can axially locating, can transmit the device of torque again.In the prior art, generally be to adopt key to transmit torque, circumferentially to locate by realizations such as jump rings, processing is difficulty relatively, and can not freely locate after processing.The common method that also has is exactly the adapter sleeve of employing standard, but price is higher relatively.
Summary of the invention
The purpose of this utility model is at problems of the prior art, and the tightening device that a kind of cost is low, can freely locate is provided.
The utility model is to realize this purpose by following structure: the utility model comprises rotating shaft and rotary component, has the mounting hole of truncated cone shape in the rotary component, and the minimum diameter of mounting hole is greater than the diameter of rotating shaft.Elastic expansion-sleeve is the middle vertically truncated cone shape that has through hole, and its shape is corresponding with the mounting hole of rotary component, and the elastic expansion-sleeve sidewall has the telescopic chute of perforation vertically, and elastic expansion-sleeve is nested with outside rotating shaft, and rotary component is nested with outside elastic expansion-sleeve.The mounting hole sidewall vertical direction of truncated cone shape has guiding groove, and elastic expansion-sleeve outer side wall vertical direction has the tightening groove, tapping in the tightening groove, and guiding groove is corresponding with tightening groove position, is combined to form the tightening hole.Cock screw is arranged in guiding groove and the tightening groove, and with the tightening groove by being threaded.
The utility model presses down rotary component by Cock screw, has also held rotating shaft when making elastic expansion-sleeve hold rotary component tightly tightly, thereby can realize the tightening of rotary component and rotating shaft.This tightening apparatus structure is simple relatively, and low cost of manufacture is easy for installation, and can realize freely locating.

Fig. 2 is the plane structure schematic representation of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, this tightening device comprises rotating shaft 5 and rotary component 1 (runner), has the mounting hole of truncated cone shape in the runner 1, and the minimum diameter of mounting hole is greater than the diameter of rotating shaft 5.Elastic expansion-sleeve 6 is for having the truncated cone shape of through hole in the middle of vertically, and its shape is corresponding with the truncated cone shape mounting hole, and elastic expansion-sleeve 6 sidewalls have the telescopic chute 7 of perforation vertically, makes the elastic member that its formation can radial expansion.Elastic expansion-sleeve 6 is nested with outside rotating shaft 5, and runner 1 is nested with outside elastic expansion-sleeve 6.Runner mounting hole sidewall vertical direction symmetry has two guiding grooves 4, and elastic expansion-sleeve 6 outer side wall vertical direction symmetries have two tightening grooves 3, tapping in the tightening groove, and guiding groove 4 is corresponding with tightening groove 3 positions, is combined to form the tightening hole.Cock screw 2 is arranged in guiding groove 4 and the tightening groove 3, and with tightening groove 3 by being threaded.
Turn Cock screw during work, screw is descending, the screw end face with runner is pressed down after the runner end face contacts, the mounting hole of runner contacts with the intimate of elastic expansion-sleeve, makes runner and elastic expansion-sleeve tightening.Simultaneously, under the effect of pressure and telescopic chute, elastic expansion-sleeve shrinks, and rotating shaft is held tightly, makes elastic expansion-sleeve and rotating shaft tightening in runner.So just realized the tightening of rotating shaft and runner.When needing to adjust the position location, only need loosening screw to reorientate and get final product.
