Abstract
The invention discloses a compact single ball head, which comprises a ball head body provided with a necking and a containing cavity and a steel ball positioned in the containing cavity, and is characterized in that the wall of the containing cavity is provided with an annular stress groove. The invention also discloses a processing method of the compact single ball head and a packaging cap for processing, wherein the processing method comprises the following steps: (1) coating grease on the steel balls; (2) placing the steel balls into the accommodating cavity through the necking of the ball head body; (3) covering a packaging cap on the end part of the ball head body; (4) and the end part of the ball head body is bent towards the accommodating cavity along the annular stress groove in a mode of manually knocking or extruding the press-fitting working surface by a press machine, so that the necking is continuously reduced until the steel ball is encapsulated in the accommodating cavity. The packaging cap comprises a funnel-shaped cavity and a packaging cap with a press-fitting working face, wherein the funnel-shaped cavity is composed of a funnel wall and a funnel neck, and the funnel wall and the funnel neck are respectively in a cone shape and a cylinder shape.
Description
Technical field
The present invention relates to the ball head.
Background technique
The ball head is widely used because of it can carry out the end structure that the universal rolling fricting movement is used as other part, especially is applied to structural requirement compactly, can not adorn the occasion of ball again from the rear portion.Single ball head then is a kind of the most frequently used ball head, and it comprises bulb body that is provided with reducing and receiving cavity and the steel ball that is positioned at receiving cavity.Existing processing method mainly contains two kinds, and a kind of method is to adopt freezing mode through the reducing of bulb body steel ball to be encapsulated in the receiving cavity.Because the method requires the magnitude of interference of reducing can not be too big, therefore, there is the risk that comes off out in steel ball, makes functional reliability bad, particularly for the compact type list ball head of single-piece or small lot processing, and processing difficulties not only, and also processing cost is higher.Another kind method is to process bigger receiving cavity earlier, and the threading at the outer wall top of receiving cavity tightens up reducing through specialized nut, thereby steel ball is encapsulated in the receiving cavity again.Though the method can prevent that steel ball from coming off, because outside thread is easy cracked from root, therefore, the intensity of bulb body can receive very big influence.
Summary of the invention
An object of the present invention is provides a kind of compact type list ball head to above-mentioned deficiency.
Another object of the present invention provides a kind of processing method of compact type list ball head, and the encapsulation caps that is used for said processing method.
Compact type list ball head of the present invention: comprise bulb body that is provided with reducing and receiving cavity and the steel ball that is positioned at receiving cavity, it is characterized in that: the chamber wall of said receiving cavity is provided with the belt stress groove.
In the technique scheme, the end edge of said bulb body is a chamfering.
In the technique scheme, the cone angle of said chamfering is 90 °.
The processing method of compact type list ball head of the present invention: may further comprise the steps:
Apply grease on steel ball; And
Said steel ball is inserted in the receiving cavity through the reducing of bulb body, and wherein, the chamber wall of said receiving cavity is provided with the belt stress groove, and the end edge of said bulb body is a chamfering;
Encapsulation caps is covered on the end of said bulb body; Wherein, Said encapsulation caps is provided with the funnel-shaped chamber that is made up of hopper walls and filler neck and press-fits working surface, and said hopper walls and filler neck are respectively frustoconic shape and cylindrical, and the end of said bulb body is positioned at funnel-shaped chamber; Its end edge that is chamfering contacts with hopper walls, and the projection of said steel ball gets in the filler neck; And
Knock or the said mode that press-fits working surface of press extruding with manual work, the end that makes said bulb body, causes said reducing constantly to be contracted to said steel ball and is encapsulated in the said receiving cavity to the receiving cavity inner bending along the belt stress groove.
In the technique scheme, the cone angle of said hopper walls is 60 °.
In the technique scheme, the cone angle of said chamfering is 90 °.
The present invention is used for the encapsulation caps of the processing method of said compact type list ball head: comprise the encapsulation caps that is provided with funnel-shaped chamber and press-fits working surface; Said funnel-shaped chamber is made up of hopper walls and filler neck, and said hopper walls and filler neck are respectively frustoconic shape and cylindrical.
In the technique scheme, the cone angle of said hopper walls is 60 °.
The present invention is through being provided with belt stress groove and chamfering on the bulb body; The end of bulb body is out of shape along the belt stress groove location in course of working, and to the receiving cavity inner bending, the thickness distribution of crushed element is more even; Outside dimensions changes mellow and full; Can not push receiving cavity, further cooperate the use of encapsulation caps, then can make reducing constantly be contracted to steel ball and be encapsulated in the receiving cavity.Solved not only that the steel ball that existing compact type list ball head exists can come off, the affected problem of bulb body intensity, and provide a kind of and produced in batches, be easy to realize, processing method with low cost and the encapsulation caps that is used to process.
