Abstract
The invention discloses a ball pin. The ball pin comprises an insertion portion facing an elastic device and a recessed surface portion facing a ball. The recessed surface portion comprises a cylindrical surface holding the circumferential wall of the ball and a conical surface holding the ball. The ball pin is a connecting piece arranged between the elastic device and the ball, and the set pressure applied on one application surface by the ball can be guaranteed. The insertion portion of the ball pin is inserted in the elastic device, and the ball is held in the recessed surface portion, so that the set pressing force is provided for the ball while good rolling performance of the ball is guaranteed. More specifically, the recessed surface portion is provided with the cylindrical surface and the conical surface, so that good rotation performance of the ball is guaranteed, and the processing difficulty is reduced.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of ball pin.
Background technique
At present, in ball spring workpiece, the pressure that the rollability of ball and spring provide can not be taken into account simultaneously.
Therefore be badly in need of proposing a kind of workpiece taking into account pressure and rolling force.
Summary of the invention
Object of the present invention provides a kind of ball pin, to solve in above-mentioned prior art problem one or more.
The present invention proposes a kind of ball pin, comprises the cartridge part towards elastic device and the concave part towards ball, and concave part comprises the cylndrical surface for holding ball perisporium and the conical surface for holding ball.
Ball pin provided by the invention, for the link between elastic device and ball, ensure that ball has the pressure of setting size to certain application surface, the cartridge part of ball pin provided by the invention is plugged in elastic device, ball is contained in concave part, the basis of the good rollability of guarantee ball gives the pressure of ball setting; More specifically, concave part has cylndrical surface and conical surface, ensures the rotatability that ball is good, and reduces difficulty of processing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of mode of execution of a kind of ball pin that the present invention proposes;
Fig. 2 be a kind of ball pin shown in Fig. 1 partly cut open figure.
Embodiment
As shown in Figure 1, 2, the present invention proposes a kind of ball pin, comprises the cartridge part 1 towards elastic device and the concave part 2 towards ball, and concave part 2 comprises the cylndrical surface 21 for holding ball perisporium and the conical surface 22 for holding ball.
The invention provides a kind of ball pin, for the link between elastic device and ball, ensure that ball has the pressure of setting size to certain application surface, the cartridge part 1 of ball pin provided by the invention is plugged in elastic device, ball is contained in concave part 2, the basis of the good rollability of guarantee ball gives the pressure of ball setting; More specifically, concave part 2 has cylndrical surface 21 and conical surface 22, ensures the rotatability that ball is good, and reduces difficulty of processing.
The above is only optimal way of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, these also should be considered as within protection scope of the present invention.
Claims (1)
