Abstract
The invention relates to a combined positioning pin shaft device, which belongs to the field of machinery. The combined positioning pin shaft device is provided with a taper sleeve, and is characterized in that: the inner sidewall of the taper sleeve has a conical surface-shaped structure; a cone is arranged in a cavity of the taper sleeve; a flange is positioned at one end of the taper sleeve, and is fastened together with the cone by a bolt; the flange and the cone are positioned by a cylindrical pin; and a screwed hole is reserved at the position of a centre line of the cone, and is screwed together with the bolt. The combined positioning pin shaft device can meet requirements on positioning between two large parts. Before integral mounting, the parts are fixed well and are both provided with circular holes with high accuracy and smooth finish; and in assembly, a combined positioning pin shaft is inserted into the circular holes, outer circles are increased due to the mutual movement of two conical surfaces in the pin shaft, and then the pin shaft is tightly attached to the circular holes, so that the combined positioning pin shaft device has the characteristics of capability of meeting the positioning requirements, good positioning effect and convenient assembly and disassembly.
Description
Technical field
The present invention relates to mechanical field, especially a kind of integrated positioning pin shaft device.
Background technique
As everyone knows, orientation type between two component that do not move relatively, traditional method are used and are sold directly to households or the taper pin location, though this mode is simple, but have a lot of drawbacks: direct selling or taper pin size are restricted, are applicable between the stressed two little parts; The precision that direct selling and taper pin are reamed influences greatly; Sell directly to households and taper pin bad control of precision after using once, recycling rate of waterused is low.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of integrated positioning pin shaft device, can be applicable to two positioning requirements between the heavy parts, before the integral installation, fix, process together in the good circular hole of precision and degree of finish, the circular hole of during assembling the integrated positioning bearing pin being packed into, by moving mutually of two conical surfaces in the bearing pin, make cylindrical increase, allow bearing pin and circular hole fit tightly, satisfy positioning requirements, good positioning effect, easy accessibility.
The technical solution adopted for the present invention to solve the technical problems is: a kind of integrated positioning pin shaft device, be provided with tapered sleeve, it is characterized in that the tapered sleeve madial wall is the cone-shaped structure, the tapered sleeve inner chamber is provided with cone, flange is positioned at tapered sleeve one end, tighten together through screw between flange and the cone, locate through straight pin between flange and the cone.
The present invention also can realize by following measure: the position of center line place of cone is a tapped hole, and this tapped hole and screw threads lump together.
The invention has the beneficial effects as follows, can be applicable to two positioning requirements between the heavy parts, before the integral installation, fix, process the good circular hole of precision and degree of finish together, the circular hole of during assembling the integrated positioning bearing pin being packed into by moving mutually of two conical surfaces in the bearing pin, makes cylindrical increase, allow bearing pin and circular hole fit tightly, satisfy positioning requirements, good positioning effect, easy accessibility.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention
1. flanges among the figure, 2. tapered sleeve, 3. cone, 4. screw, 5. straight pin.
Embodiment
In Fig. 1, the present invention is provided with tapered sleeve 2, tapered sleeve 2 madial walls are the cone-shaped structure, tapered sleeve 2 inner chambers are provided with cone 3, flange 1 is positioned at tapered sleeve 2 one ends, tightens together through socket head screw 4 between flange 1 and the cone 3, locatees through straight pin 5 between flange 1 and the cone 3, the position of center line place of cone 3 is a tapped hole, and this tapped hole and screw 4 spin together.
The present invention is fitted together flange 1, tapered sleeve 2, cone 3 by screw 4, with straight pin 5 location, prevent that both from relatively rotating between flange 1 and the cone 3, and this moment, screw 4 can not be stressed, and screwing on does not come off gets final product.Said mechanism integral body is put into the two part circular holes that need the location.Owing between tapered sleeve 2 and the cone 3 the identical cooperation conical surface is arranged, tapered sleeve 2 is monolateral simultaneously a suitable slit, so when stubborn during through screw 4, tapered sleeve 2 relatively moves with cone 3, changes by the conical surface, makes the tapered sleeve cylindrical increase, be fitted in closely in the circular hole of part, thus the positioning action of playing.
Adopt this integrated positioning bearing pin, diameter is than big many of common direct selling or taper pin, thereby guarantees to have enough intensity.Since tapered sleeve cylindrical size variation, accurate positioning.Cone 3 centerline are provided with screw thread, easy disassembly.Because circular hole and part all are that machining forms, and save drilling and tapping operation in the assembling, labor intensity reduces, and efficiency improves.
Claims (2)
1. an integrated positioning pin shaft device is provided with tapered sleeve, it is characterized in that the tapered sleeve madial wall is the cone-shaped structure, and the tapered sleeve inner chamber is provided with cone, and flange is positioned at tapered sleeve one end, tightens together through screw between flange and the cone, locatees through straight pin between flange and the cone.
2. according to the described integrated positioning pin shaft device of claim 1, the position of center line place that it is characterized in that said cone is a tapped hole, and this tapped hole and screw threads lump together.
