Abstract
The invention discloses a non-clearance-fit hinge pin. The non-clearance-fit hinge pin comprises a hinge pin body (2) matched with a pin hole (1), and is characterized in that the outer contour of the hinge pin body (2) is cylindrical, a conical hole (3) is formed in the hinge pin body (2) in the axial direction, a conical pin (4) is matched with the conical hole (3), the small-diameter end of the conical pin (4) is provided with a threaded hole (5), the edge (7) of an end cover (6) matched with the hinge pin body (2) abuts against the hinge pin body (2), and the end cover (6) is provided with a tensioning bolt (8) in threaded connection with the threaded hole (5). The non-clearance-fit hinge pin is simple in structure and ingenious in design, non-clearance assembly can be carried out at the normal temperature, and the non-clearance-fit hinge pin can bear certain shearing stress.
Description
Technical field
The present invention relates to a kind of pin shaft structure, particularly a kind of gapless coordinates bearing pin.
Background technique
Traditional bearing pin, pin-and-hole wants to realize gapless and coordinates, and in the time of equipment, need to carry out hot charging or cold charge, this assembling mode complex operation, and cost is relatively high.If when the motion of two accessory generation bearing pin radial direction at two pin-and-hole places that match, bearing pin can damage even fracture because bearing shearing stress, has certain potential safety hazard simultaneously.Therefore wish to find now a kind of pin shaft structure that can address the above problem.
Summary of the invention
The present invention is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, can under normal temperature environment, carry out gapless assembling, and the gapless that can bear certain shearing stress coordinates bearing pin.
Technical solution of the present invention is: a kind of gapless coordinates bearing pin, comprise the bearing pin body 2 matching with pin-and-hole 1, it is characterized in that: be cylindrical at the external frame of described bearing pin body 2, axially be provided with taper hole 3 along it bearing pin body 2 is interior, be provided with taper pin 4 with taper hole 3 matches, taper pin 4 diameters offer tapped hole 5 on less one end, and the edge 7 of the end cap 6 matching with bearing pin body 2 withstands on bearing pin body 2, and on end cap 6, is provided with the tension bolt 8 being threaded with tapped hole 5.
Compared with the existing technology, tool has the following advantages in the present invention:
The gapless of the embodiment of the present invention coordinates bearing pin, it is simple in structure, design ingenious, it for the bearing pin of conventional construction in the time carrying out gapless assembling, need to carry out cold charge or hot charging, the principle that utilization is expanded with heat and contract with cold allows the diameter of bearing pin or pin-and-hole change and to assemble, and recovers so the gap of normal temperature between the latter two again and eliminates; This method complex operation, step are more, and its assembly cost is higher, and difficulty comparatively when dismounting.In order to address the above problem, the application designs a kind of bearing pin body and taper pin structure of mutual socket, coordinates, like this when taper pin is in bearing pin body when axial motion between the two by cone shape hole, can allow bearing pin body tensioner in pin-and-hole, realize gapless and coordinate.The appearance of this structure, has exempted the process and the operation that in traditional bearing pin assembly process, heat or freeze, and it,, than conventional pin axle construction, can also bear larger shearing stress simultaneously.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Brief description of the drawings
Fig. 1 is the decomposing state schematic diagram of the embodiment of the present invention.
Fig. 2 is the assembled state schematic diagram of the embodiment of the present invention.
Embodiment
Below in conjunction with brief description of the drawings the specific embodiment of the present invention.As shown in Figure 1 and Figure 2: a kind of gapless coordinates bearing pin, comprise the bearing pin body 2 matching with pin-and-hole 1, the external frame of this bearing pin body 2 is cylindrical, inside at bearing pin body 2 axially offers taper hole 3 along it, be provided with taper pin 4 with taper hole 3 matches, on one end that on this taper pin 4, diameter is less, offer tapped hole 5, also be provided with end cap 6 with bearing pin body 2 matches, on this end cap 6, be provided with the tension bolt 8 being threaded with tapped hole 5, be that end cap 6 is positioned at the less one end of taper hole 3 diameters, and the edge 7 of end cap 6 withstand on bearing pin body 2.
The gapless of the embodiment of the present invention coordinates the working procedure of bearing pin as follows: because the external frame of the bearing pin body 2 of the present embodiment is consistent with common bearing pin, therefore bearing pin body 2 can be plugged in the pin-and-hole 1 matching on the hinged workpiece of two needs, now gapped between bearing pin body 2 and pin-and-hole 1, bearing pin body 2 enters after pin-and-hole 1, taper pin 4 is inserted in the taper hole 3 of bearing pin body 2, and the edge of end cap 67 is withstood on to fastening on bearing pin body 2, tension bolt 8 is screwed in the tapped hole 5 of offering on taper pin 4 less one end of diameter, and screw this tension bolt 8, under the effect of tension bolt 8, taper pin 4 is towards end cap 6 direction motions, due to the motion of taper pin 4, allow the excircle of bearing pin body 2 that small deformation occurs, gap between bearing pin body 2 and pin-and-hole 1 is eliminated, the gapless of utilizing this device can realize between bearing pin and pin-and-hole coordinates or interference fit.
Simultaneously, the bearing pin of the present embodiment is actually by the bearing pin body 2 of tube-in-tube structure and 4 two parts of taper pin and forms, and between these two parts, coordinate by a taper hole 3 with several angle, therefore than traditional pin shaft structure, the present embodiment can bear larger shearing stress.
Claims (1)
1. a gapless coordinates bearing pin, comprise the bearing pin body (2) matching with pin-and-hole (1), it is characterized in that: be cylindrical at the external frame of described bearing pin body (2), in bearing pin body (2), be axially provided with taper hole (3) along it, be provided with taper pin (4) with taper hole (3) matches, taper pin (4) diameter offers tapped hole (5) on less one end, it is upper that the edge (7) of the end cap (6) matching with bearing pin body (2) withstands on bearing pin body (2), and on end cap (6), be provided with the tension bolt (8) being threaded with tapped hole (5).
