Abstract
The utility model discloses a closing device for slender axles end pressure equipment spare, it includes handle, round pin axle, spring, depression bar, bush, position sleeve and support. The support is provided with a stand column, the right wall of the middle section of the stand column is fixedly connected with a horizontal guide block, and the support and the guide block are provided with an upper through hole and a lower through hole which are coaxial and are respectively provided with a bushing and a positioning sleeve. After a compression bar with a conical tip is sleeved with a spring, the compression bar is inserted into an inner hole of the bushing from the upper end to form a telescopic mechanism. The left end of the handle is hinged with the top end of the upright post through a pin shaft, a downward ball head top is arranged at the left end of the handle corresponding to the top end of the pressing rod, and the handle is matched with the top end of the pressing rod through the ball head top. The handle presses downwards to push the pressure lever to push the center point to push the center hole of the pressed shaft, and the push shaft is inserted into the accessory hole. The utility model has the advantages of being simple in structure and easy in operation, the axle atress is even, and installation quality is good, efficient.
Description
Technical field
The utility model relates to a kind of micro pressure machinery, particularly a kind ofly is used for the hold down gag that elongated axle head and accessory mutually press-fit.
Background technology
Worm screw in the small-power petrol engine belongs to a kind of slender rod type precision component, and its axle head is provided with the gear that matches, and both cooperate for interference fit, need apply external force during assembling.Prior art can realize press-fiting with forcing press, but operation easier is big, and man-machine harmony is poor, inefficiency, and stand-by time is long, and is economical inadequately.Conventional end user's hammer method of hitting realizes assembling in the production scene, and this method is simple, can effective operation.Its deficiency is the impulsive force inequality, easily cause worm screw distortion and influence product quality, and the workman works greatly, and production efficiency is low, can not satisfy requirement of mass production.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of hold down gag that elongated axle head press-fits accessory that is used for, this apparatus structure is simple, processing ease, uniform force application, press-fit the efficient height, quality is good.
The utility model is achieved through the following technical solutions technical goal.
A kind ofly be used for the hold down gag that elongated axle head press-fits accessory, it comprises handle, bearing pin, spring, depression bar, lining, positioning sleeve and bearing.Described bearing is a main component, and its bearing right-hand member is provided with upright column up.Described handle left end is hinged in the column top end opening groove of bearing and by bearing pin, the guide pad of the fixedly connected level of column stage casing right side wall of bearing, and bearing is provided with coaxial through hole up and down with guide pad.Improvements are: be provided with lining in the through hole of described guide pad, the depression bar pocketed springs inserts the lining endoporus and constitutes elastic telescopic structure up and down from the upper end.The positioning sleeve of matched in clearance is housed in the through hole of described bearing.
Handle in the said structure cooperates with the depression bar top by the bulb top, and handle is exerted pressure downwards depression bar is moved downward, and depression bar acts on by the centre bore of last item with beveled tip, and impeller-hub inserts in the accessory hole.During last handle, push rod moves reinstatement under the effect of spring.
The utility model compared with prior art has following good effect:
1, lever construction is simple, easy to manufacture, easy to operate;
2, the beveled tip roof pressure of vertical depression bar is pressed the centre bore of slender axles, does the force on axial line, and axle is stressed evenly, is difficult for flexural deformation;
3, disposable being press-fit into place, steady quality press-fits the efficient height.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is further described.
A kind of hold down gag that elongated axle head press-fits accessory that is used for shown in the drawings, it comprises handle 1, bearing pin 2, spring 3, depression bar 4, lining 5, positioning sleeve 6 and bearing 7.Described bearing 7 is a main component, and its bearing 7 right-hand members are provided with upright column up, the fixedly connected guide pad 7.1 that is parallel to bearing 7 of column stage casing right side wall, and bearing 7 is provided with coaxial through hole up and down with guide pad 7.1.Be provided with lining 5 in the through hole of guide pad 7.1, have depression bar 4 pocketed springs 3 of beveled tip after, insert lining 5 endoporus from the upper end and constitute elastic telescopic structure up and down.The positioning sleeve 6 of matched in clearance is housed in the through hole 7.2 of described bearing 7, and the endoporus of positioning sleeve 6 is greater than elongated axle head diameter of join.Present embodiment is the worm shaft of automobile accessories, and axle head press-fits gear, and this axle head diameter is φ 25mm, and positioning sleeve 6 internal diameters are φ 25.5mm.Handle 1 in the utility model is a driving lever, and handle 1 left end is hinged in the column top end opening groove of bearing 7 and by bearing pin 2, and the top of the corresponding depression bar 4 of the left end of handle 1 is provided with bulb top 1.1 down.Handle 1 cooperates with depression bar 4 tops by bulb top 1.1, holds handle 1 and exerts pressure downwards and promote depression bar 4 and move downward, and depression bar 4 acts on the centre bore of being pressed worm shaft with beveled tip, promotes in the gear hole that the worm shaft insertion is equipped with.During last handle 1, push rod 4 moves reinstatement under the effect of spring 3.
The utility model is a kind of hold down gag of lever construction, and is simple in structure, processing ease, spy Point be depression bar do the force on axial line, axle is stressed evenly, is difficult for flexural deformation, steady quality, Press-fit the efficient height.
