Abstract
The present invention relates to a withdrawing pin which is in a connecting type for axles. The withdrawing pin is a cylindrical pin with an inclined cylindrical surface. An axial line of a pin hole on an axle base is tangential with the outer circle of an axial hole. An axle rod is provided with a circular-arc slot with corresponding radius and depth. After assembly, a nut on the tail end of the pin is tightly screwed. The cylindrical surface of the pin is matched with the pin hole, and the inclined cylinder surface and the circular-arc slot of the axle rod are automatically adjusted and matched. Thus, tight connection, no gap and no looseness are guaranteed. Thus, when the axle rod is in the processes of rotation and backward and forward movement, the sufficient contact with a cutting surface is guaranteed at any time, and the cutting stress of the material of a matching part is reduced. The disassembly can be carried out by only screwing off the nut, and the withdrawing pin can be loosened and pulled out. The present invention is suitable for the fastening connection between the axle rod and the axle hole.
Description
Technical field
The present invention relates to a kind of Withdrawing pin, be a kind of with connecting pattern, be applicable to the fastening connection between axostylus axostyle and axis hole.
Background technique
In the design and application of mechanical structure, the fastening connection between axostylus axostyle and axis hole generally selects for use key connecting or pin to connect.Key connecting is used to prevent the circumferential rotation of axostylus axostyle, but often and big gap arranged between axis hole; Pin connects can prevent that axostylus axostyle from circumferentially rotating and axial float, but often not quick detachable after assembling.More than two kinds of connecting modes therefore because key or pin be when bearing shearing force, area of contact is very little, is easy to produce the conquassation phenomenon of surface of contact material and loosening the inefficacy.This is a urgent problem in this field.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of circumferential rotation of axostylus axostyle and axial float of preventing and also can avoid the surface of contact material to pull pin because of loosening the pushing away of conquassation.
For solving the problems of the technologies described above, Withdrawing pin of the present invention is a kind of straight pin that a tilted cylindrical envelope face is arranged, and two cylndrical surface form an angle.
The pin end has screw stud, and with a nut screwing clamping, the other end is the straight pin section.
The present invention can make axostylus axostyle in rotation and play process, and shear plane fully contacts, thereby reduces the shearing stress of cooperation place.
Description of drawings
Fig. 1 is that the present invention pushes away the plan view of pulling pin;
Fig. 2 is that the present invention pushes away the plan view of pulling pin;
Fig. 3 is that the present invention pushes away the plan view in the scheme of installation of pulling pin;
Fig. 4 is that the present invention pushes away the plan view in the scheme of installation of pulling pin.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
The present invention pushes away and pulls pin as depicted in figs. 1 and 2, is on the periphery of terminal threaded straight pin is pulled pin in traditional pushing away, processing is one identical with the periphery diameter, with the disc that pin axis has angle, pin end maximum cross-section diameter equals the pin diameter.The pin end has screw stud, and with a nut screwing clamping, the other end is the straight pin section.
As shown in Figure 3 and Figure 4, pin-and-hole axis and axis hole cylindrical on the axle bed 1 are tangent, and the arc groove of a corresponding radius and the degree of depth is arranged on the axostylus axostyle 2.Be equipped with the set screw nut 3 of tightening pin 4 ends, pin 4 cylinders cooperate with pin-and-hole, and the batter post face is adjusted automatically with the axostylus axostyle arc groove and cooperated, and it is loosening to guarantee to connect tight no gap.Only need turn on nut 3 when dismounting gets final product.
In sum, this Withdrawing pin connects closely, can prevent that axostylus axostyle from circumferentially rotating and axial float.The fit system of batter post face can prevent the surface of contact conquassation simultaneously, improves working life, the dismounting of being more convenient for.
