Description

Shaft pin

Technical Field

The utility model belongs to the mechanical connecting piece field specifically is a pivot.

Background

At present, in the assembly of machine parts, the connection of positioning and limiting among all the parts is realized by adopting a sunk embedding mode of shaft pins, cylindrical pins, conical pins and the like. When the connecting piece needs to be positioned and connected by adopting the shaft pin due to the function, sometimes a positioning hole needs to be formed in the shaft pin, and the connecting piece is fixed by driving the positioning pin into the positioning hole. After the shaft pin is used for a long time, the shaft pin is not easy to be stuck due to rusting when being in contact with an object fixedly connected with the shaft pin, is not easy to detach, can damage the shaft pin when rotating again, can generate radial shearing force for a positioning pin in a positioning hole of the shaft pin, and is easy to cause shearing damage of the positioning pin.

SUMMERY OF THE UTILITY MODEL

the utility model aims to solve the problem that overcomes prior art not enough, provide a pin that fixity is good and easily dismantle.

The utility model adopts the technical proposal that: a shaft pin comprises a baffle, a shaft body, a shaft head and a pin, wherein the baffle and the shaft head are respectively positioned at two ends of the shaft body, the shaft body is of a smooth cylindrical structure, the shaft head comprises a positioning section, a threaded section and a positioning hole, the positioning section is positioned at the joint of the shaft head and the shaft body, the threaded section is connected with the positioning section, and the positioning hole is arranged at the front end of the threaded section; set up an oil filler point in the axle body, the oil filler point runs through the axle body, and one end setting is in baffle department, and the other end setting sets up at the position of axle body and the discontiguous of spindle nose location section, sets up the helicitic texture in the axle body inboard that is close to the constitution oil filler point of baffle one side, sets up the screw plug in baffle department, the screw plug surface be provided with the inboard matched with helicitic texture of axle body, the pin is pegged graft in the locating hole.

Preferably, the diameter of the baffle is larger than the diameter of the shaft body.

Preferably, the diameter of the positioning section is smaller than that of the shaft body.

Preferably, the maximum diameter of the thread teeth of the thread section is consistent with the diameter of the positioning section.

Preferably, the positioning hole is a through hole.

the beneficial effects of the utility model reside in that:

1. The fixity is good. The shaft head is provided with a thread section to increase the connection strength of the connecting piece, and the shaft head is also provided with a positioning hole to insert a pin into the positioning hole to realize secondary fixation.

2. Is convenient to disassemble. Set up an oil filler point in the axle body, when the axle round pin is rusted, with the downthehole lubricating oil that injects of oil filler point, lubricating oil flows into axle body and spindle nose junction along the oil filler point, because the diameter of spindle nose location section is less than the diameter of axle body so lubricating oil can be light get into the screw thread section and the locating hole department of spindle nose department, so just can easily dismantle.

3. The threaded plug of the oil filling hole is arranged at the baffle, and the threaded plug can be screwed into the oil filling hole at ordinary times, so that the phenomenon that a channel is blocked when foreign matters enter the oil filling hole is avoided.

Drawings

Fig. 1 is a schematic structural view of the present invention.

Wherein the reference numbers are as follows:

1. A baffle plate; 2. a shaft body; 21. an oil filler hole; 22. a threaded plug; 3. a shaft head; 31. a positioning section; 32. a threaded segment; 33. positioning holes; 4. a pin.

Detailed Description

The invention will be further described with reference to the accompanying drawings:

A shaft pin comprises a baffle plate 1, a shaft body 2, a shaft head 3 and a pin 4, wherein the baffle plate 1 and the shaft head 3 are respectively positioned at two ends of the shaft body 2, the shaft body 2 is of a smooth cylindrical structure, the shaft head 3 comprises a positioning section 31, a threaded section 32 and a positioning hole 33, the positioning section 31 is positioned at the joint of the shaft head 3 and the shaft body 2, the threaded section 32 is connected with the positioning section 31, and the positioning hole 33 is arranged at the front end of the threaded section 32; set up an oil filler point 21 in axle body 2, oil filler point 21 runs through axle body 2, and one end setting is in baffle 1 department, and the other end setting is in the position of axle body 2 and 3 contactless positions of section 31 of spindle nose, and 2 inboards of axle body that constitute oil filler point 21 near baffle 1 one side set up the helicitic texture, set up screw plug 22 in baffle 1 department, screw plug 22 surface be provided with 2 inboard matched with helicitic texture of axle body, pin 4 is pegged graft in locating hole 33.

The diameter of the baffle 1 is larger than that of the shaft body 2, the diameter of the positioning section 31 is smaller than that of the shaft body 2, the maximum diameter of the thread teeth of the thread section 32 is consistent with that of the positioning section 31, and the positioning hole 33 is a through hole.
