Abstract
The utility model discloses a pin stopping device of a pin coupler and relates to the technical field of coupler connecting devices. The pin stopping device comprises two coupling halves including a first coupling half and a second coupling half, pin holes are symmetrically processed on the two coupling halves, a step is positioned outside a first pin hole of the first coupling half, and an annular groove is arranged at the step, a second pin hole processed on the second coupling half is bind, and a small hole is processed at the bottom of the second pin hole, so that pins are limited axially by low-carbon steel wires wound into the annular groove after the pins of the coupler are assembled. The pin stopping device has the advantages of convenience and rapidness in changing and detaching, work procedures of processing pin stopping plates and processing screw holes on the two coupling halves are omitted, and processing cost is saved.
Description
Technical field
The utility model relates to a kind of coupling, specifically is a kind of pin coupler backing pin device; Be mainly used in being connected of motor and retarder high speed shaft in the machinery.
Background technique
At present the nylon pin of standard HL type pin coupler is to lean against processing screw hole on two half-couplings, and connecting the backing pin plate with bolt respectively at two ends, to limit the string of nylon pin moving.Generally all smaller because of bolt specification, when needing to change after coupling uses a period of time, bolt is all corrosions generally, and is very difficult and break easily during dismounting, reduced the replacing working efficiency.
Summary of the invention
In order to solve the shortcoming of above-mentioned prior art, the utility model provides a kind of pin coupler backing pin device, and it is quick and convenient to make that pin changes, and saves processing backing pin plate and the operation of processing screw hole on two half-couplings.
The utility model is realized with following technological scheme: a kind of pin coupler backing pin device, comprise two half-couplings, and symmetry has column pin hole on two half-couplings, and the nylon pin is installed in the column pin hole; Column pin hole adds the worker one step is arranged on half-coupling therein, opens an annular groove on this step, and device has pair nylon pin to carry out the limit stoper of axial limiting in the annular groove; Column pin hole on another half-coupling is a blind hole, and has a knock hole in the bottom, hole.
The beneficial effects of the utility model are: pin changes quick and convenient; Saved processing backing pin plate and on two half-couplings the operation of processing screw hole, saved processing cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, half-coupling; 2, limit stoper; 3, nylon pin; 4, knock hole, 5, step.
Embodiment
As shown in drawings, pin coupler backing pin device has two half-couplings 1, and symmetry has column pin hole on two half-couplings 1, and nylon pin 3 is installed in the pin-and-hole.Column pin hole adds worker's one step on half-coupling 1 therein, and on this step processing annulate shaft one all annular grooves, be provided with the limit stoper 2 that nylon pin 3 is carried out axial limiting in the annular groove.Limit stoper 2 adopts the mild steel wire that is entangled in the annular groove in the present embodiment.Column pin hole on another half-coupling 1 is a blind hole, and has a knock hole 4 in the blind hole bottom.
Owing to adopted said structure, after coupling nylon pin 3 assembles, in annular groove, be entangled to mild steel wire, just pin has been played the axial limiting effect.As long as mild steel wire is cut off, the knock hole 4 bottom second half coupling just can easily eject nylon pin 3 when changing coupling.
Claims (2)
1. a pin coupler backing pin device comprises the half-coupling (1) that two symmetries are installed, and goes up symmetry at two half-couplings (1) and has column pin hole, and nylon pin (3) is installed in the column pin hole; It is characterized in that: the last column pin hole of a half-coupling (1) adds the worker therein a step (5), opens an annular groove on this step, and device has pair nylon pin (3) to carry out the limit stoper (2) of axial limiting in the annular groove; Column pin hole on another half-coupling (1) is a blind hole, and has a knock hole (4) in the blind hole bottom.
2. pin coupler backing pin device according to claim 1 is characterized in that: described limit stoper (2) is for being entangled in the mild steel wire in the annular groove.
