Description

A kind of axis of guide

Technical field

This utility model is related to mechanical connection field, more particularly, it relates to a kind of axis of guide.

Background technology

In the connection of component of machine, it is a kind of conventional connected mode to be hinged, and is referred to shown in Fig. 1, i.e., one zero The shape of jaw 1 is made at certain position of part, and the shape of homalocephalus 3 is made at certain position of another part, on jaw 1 and homalocephalus 3 A hole is all provided with, then two parts is coupled together an axle 2 by homalocephalus 1 and the hole on jaw 3.

In this case, it is desirable to which the hole on jaw 1 and homalocephalus 3 must have good centering, that is, must have higher Axiality, can just make bearing pin 2 be smoothly through the hole on jaw and homalocephalus and be installed.If not higher axiality, The hole on hole and homalocephalus 3 on jaw 1 misplaces, and axle just cannot be attached installation by homalocephalus 3.

In practical operation, because homalocephalus 3 and jaw 1 are in the pre-connection separated from one another, lack positioning so that two holes Toward it is difficult to ensure that with good axiality, so that it is very inconvenient to install bearing pin.

For the problems referred to above, the solution taken at present is referred to shown in Fig. 2, and countershaft 4 top carries out chamfering 41 are processed, and a taper is formed on the top of axle 4 using chamfering 41, so that axle 4 has certain guide function, but this side Method be only suitable for holes degree of misalignment it is little in the case of, if in the case where some heavy parts or degree of misalignment are larger not Can be suitable for, therefore be accomplished by present can be applied to it is above-mentioned in the case of a kind of device.

Utility model content

For disadvantages mentioned above present in prior art, the purpose of this utility model is to provide a kind of axis of guide, Neng Goufang Just efficiently make to realize being hinged between two larger parts of heavy parts or degree of misalignment.

For achieving the above object, this utility model is adopted the following technical scheme that：

A kind of axis of guide, including guide pad and axis body, guide pad has several piece, and number is axially offered along the front end of axis body The keyway that road and guide pad match, in corresponding keyway on axis body, guide pad combines to be formed whole with axis body to guide pad Body, its radial section is in a full-circle spray pattern, and it is in inclined-plane that the front end of the keyway is arranged.

Described guide pad is no less than two pieces.

The block to backstop guide pad is additionally provided with described axis body rear end.

In above-mentioned technical scheme, this utility model has following some beneficial effect：

1. this utility model is oriented to reliability, easy to use；

2. this utility model simple structure, manufacturing cost is cheap.

Specific embodiment

The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.

With reference to shown in Fig. 3 a to Fig. 5 b, a kind of axis of guide provided by the utility model, including guide pad 11 and axis body 12, Guide pad 11 have several piece, in the present embodiment adopt two pieces of guide pads 11, axially offer along the front end of axis body 12 several with The keyway 13 that guide pad 11 matches, keyway 13 offers twice in the present embodiment, and is symmetrically opened in the upper/lower terminal of axis body 12 On, the width of keyway 13 will match with the width of guide pad 11, and guide pad 11 is corresponding to be inserted in what is opened up on axis body 12 In keyway 13 so that guide pad 11 is combined with axis body 12 and forms entirety of the radial section in a full-circle spray pattern, whole diameter of a circle Size will match with the internal diameter size in hole on required installation part, in addition, it is in one that the front position of the keyway 13 is arranged Inclined-plane.

Preferably, being additionally provided with to the block 14 of backstop guide pad 11 on the described rear end of axis body 12.

With reference to shown in Fig. 6 a, a kind of using method of the axis of guide provided by the utility model, first by every piece of guide pad 11 Medium position be all positioned on axis body 12 in the front position of corresponding keyway 13, due to during 13 front position of keyway arrange in tool There is the inclined-plane of constant slope, so the front end position of two pieces of guide pads 11 now all comes closer, constitute A font Wedge structure.Then, this axis of guide is inserted in the hole 16 of jaw 15 and the hole 18 of homalocephalus 17, now, the front end of guide pad 11 It is introduced in the hole 18 of homalocephalus 17, the middle part of guide pad 11 enters to the hole 16 of jaw 15 with axis body 12, guide pad 11 Rear end is then outside the hole 16 of jaw 15, and axis body 12 is only inserted inside the hole 16 of jaw 15.

With reference to shown in Fig. 6 b, axis body 12 is gradually moved into hole 16,18 in the presence of external force, and guide pad 11 is in keyway 13 Under the promotion on front end inclined-plane, parastate is gradually converted into by inclination, so allows for guide pad 11 and axis body 12 is combined into one The entirety of full circle, the front end of guide pad 11 for being previously entered the hole 18 of homalocephalus 17 then drives homalocephalus 17 to carry out radial displacement, directly To the centers of 17 Kong of homalocephalus 18 and the center superposition of hole 16 of jaw 15.

With reference to shown in Fig. 6 c, after 16 center superposition of hole of the centers of 17 Kong of homalocephalus 18 and jaw 15, axis body 12 just can be with Smoothly enter to the hole 16 of jaw 15, complete being articulated and connected between jaw 15 and homalocephalus 17, now, the rear end of guide pad 11 The rear end of axis body 12 is slided to along keyway 13, is lived after guide pad 11 by the backstop of block 14, also formed between guide pad 11 and axis body 12 One complete axis of guide.

Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new Type, and be not used as be to restriction of the present utility model, if in spirit of the present utility model, to the above Change, the modification of embodiment all will fall in Claims scope of the present utility model.
