Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the tool of the present invention
Body embodiment is described in detail.Many details are elaborated in the following description in order to fully understand the present invention.
But the invention can be embodied in many other ways as described herein, those skilled in the art can without prejudice to
Similar improvement is done in the case of intension of the present invention, therefore the present invention is not limited to the specific embodiments disclosed below.
Referring to Fig.1, a kind of ball-and-socket screw piece, ball-and-socket screw piece include screw 100 and metal sleeve 200；Screw 100
Include the insertion section 110 for being embedded in metal sleeve 200 and the linkage section 120 for being connected with exterior part.Embedded section 110
The inner wall of limiting slot 111 equipped with annular, metal sleeve 200 is equipped with the annular protrusion 210 coordinated with limiting slot 111 and to screw
Portion 100 forms axial limiting, and annular protrusion 210 is clearance fit in the circumferential direction of screw 100 with limiting slot 111, so that screw
It portion 100 can the rotation in metal sleeve 200.
The insertion section 110 of screw 100 is connected with metal sleeve 200, and linkage section 120 is connect with exterior part.It is embedding
Enter limiting slot 111 of the section 110 circumferentially arranged with annular.The inner wall of metal sleeve 200 is equipped with the convex annular coordinated with limiting slot 111
210 are played, annular protrusion 210 is stuck in limiting slot 111.The width of annular protrusion 210 is matched with the width of limiting slot 111, to
Forming axial limiting to screw 100 makes it that can not move axially so that ball-and-socket screw piece is more accurate, and action is more stable.
The height of annular protrusion 210 is less than the depth of limiting slot 111, forms clearance fit so that screw 100 can be in metal sleeve
Rotation in 200.Above-mentioned ball-and-socket screw piece, can more preferable modularized processing, due to screw 100 can the rotation in the metal sleeve 200,
Ball-and-socket screw piece can carry out multi-angle rotary when thus installing, it can be convenient for find suitable position and angle installation.To drop
Its low required precision to rear process various aspects and other accessories.This connection type of screw 100 and metal sleeve 200
It tests, will not cause to fall off because of rotation by pulling capacity.
And this connection type of ball-and-socket screw piece convenient for recycle, when occur parts connection it is not close when, can
To carry out dismounting recycling to ball-and-socket, the problem of avoiding the high scrappage brought by technology mode.Such as use milling machine to ball-and-socket spiral shell
Wire is processed, and 200 loose part of metal sleeve is removed, to recycle screw 100.Metallic sheath after working process
200 length of pipe can shorten, can be by making after processing if other types product needs to use the metal sleeve 200 of corresponding length
With.
The screw 100 of above-mentioned ball-and-socket screw piece, screw 100 is embedded in metal sleeve 200, by annular protrusion 210
It is connected with limiting slot 111, annular protrusion 210 forms axial limiting to screw 100, while in the circumferential direction of screw 100
For clearance fit so that screw 100 can only rotate in metal sleeve 200, cannot move axially.Above-mentioned ball-and-socket screw piece adds
Work is convenient, and screw 100 can rotate in metal sleeve 200, thus low to rear process all requirements precision, with other accessories
It is convenient for disassembly and assembly when assembly.
Further, referring to Fig.1, annular protrusion 210 is formed by 200 outer wall slot rolling of metal sleeve.Metal sleeve 200 is originally
It is suppressed in 200 outer wall of metal sleeve, outer wall forms rolling after embedded section 110 is embedded in metal sleeve 200 in place for smooth wall body
Slot, inner wall form annular protrusion 210 and coordinate to be formed to limiting slot 111.The processing method, simple for process, high yield rate.
Further, referring to Fig.1, be equipped in metal sleeve 200 with the cooperation of 110 end of embedded section for process positioning and
Prevent the limiting section 220 that screw 100 axially inwardly moves.
The crucial step of processing annular protrusion 210 is accurate positioning, the limiting slot 111 of embedded section 110 just with slot rolling
The annular protrusion 210 of formation is aligned.When processing, the embedded easy insertion of section 110 is too deep or excessively shallow, and passes through and measure embedded section 110
When position suitable, since the axial direction of metal sleeve 200 and embedded section 110 is active state, and it is easy because touching or shaking generation
It slides axially, alignment is caused to fail.Limiting section 220 can be thus equipped in metal sleeve 200 in advance, is such as existed in advance by measuring
The rolling formation of metal sleeve 200 is correspondingly embedded in section 110 and stretches into the limit protrusion of most deep position and annular protrusion is arranged in preparation
210 positions setting mark.When can not continue to be carried forward after embedded section 110 stretches into, as in place.Mark and limiting slot 111
The two is aligned, and can guarantee that limiting slot 111 is matched and annular protrusion 210 matches in 200 outer wall slot rolling of metal sleeve.And limiting section
220 can also prevent screw 100 from axially inwardly moving, and reduce the pressure of annular protrusion 210, enhance service life.
Further, metal sleeve 200 is equipped with inner chamfer.Inner chamfer can facilitate metal sleeve to be assembled with ball-and-socket screw, go
Except Assembly Interference.
Further, metal sleeve 200 is aluminum pipe.Aluminum pipe matter is soft, and machinability is strong, and annular protrusion is formed convenient for slot rolling
210。
Further, referring to Fig.1, embedded section 110 is equipped with seal groove between end and limiting slot 111, is set in seal groove
There is sealing ring 112.The design helps to promote the axial seal of ball-and-socket screw piece.
Further, referring to Fig.1, linkage section 120 includes threaded joints and turns portion convenient for turn linkage section 120
121.Portion 121 is turned close to embedded 110 position of section, may be designed as turning with the cooperation of various spanners, consequently facilitating linkage section 120 with
Exterior part connection fastening.
A kind of processing method of ball-and-socket screw piece, includes the following steps:The insertion section 110 of screw 100 is inserted into metal
In casing 200, and it is correspondingly embedded in outside metal sleeve 200 the 111 position slot rolling of limiting slot of section 110, formation is matched with limiting slot 111
The annular protrusion 210 of conjunction.The ball-and-socket screw piece simple and convenient processing method, it is high in machining efficiency.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
