Description

Auxiliary guide pin for matching and connecting two mechanical components

Technical Field

The utility model relates to a mechanical component cooperation is connected, concretely relates to supplementary round pin that draws that is used for two mechanical component cooperations to connect.

Background

In the assembly process of the armored chariot, the coaxiality requirement of a certain group of holes of two or three components is often met to ensure that a certain pin shaft or bolt can smoothly pass through the holes. See fig. 1. Two shaft holes of the first member 1 and the second member 2 are connected by a long pin shaft to form a hinge kinematic pair. Since the first member 1 and the second member 2 are constrained by other members when they are assembled on site, the moving space is limited, and it is difficult to align and align the through-holes of the two members coaxially. Referring to fig. 2, it is also difficult to assemble in the field to align and align each set of screw holes of the third member 3 and the fourth member 4 and then to connect them by a plurality of bolts 5. To solve this problem, it is conventional to make a guide pin 6 (see fig. 3), insert the small end of the guide pin into the bore of one member, strike the large end of the guide pin with a hammer, and force the bores of the two members to be coaxial. Then, the guide pin is axially advanced, and the pin to be fitted to connect the two members is subsequently fitted into the holes of the two members (see fig. 4).

The guide pin is passed through the corresponding hole groups of the two members, the handle portion of the guide pin is made longer, and after the front end of the guide pin is exposed through the member hole, the small end of the guide pin is held by hand and the guide pin is pulled out. The operation is time-consuming and inefficient, and the later removal of the pin connecting the two components is also laborious. Therefore, improvements in existing guide pins are needed.

CN204055213U discloses "an auxiliary guide pin for mounting a suspension system of a wheeled armored vehicle", which includes a conical head at the front end and a threaded protection sleeve at the rear end, wherein the end surface of the conical head is spherical, the threaded protection sleeve is a cylinder, an inner hole is axially formed, the diameter of the inner hole is greater than the outer diameter of the front end thread of a guided pin shaft, and the length of the threaded protection sleeve just covers the front end stepped shaft of the guided pin shaft; the outer diameter of the thread protective sleeve is smaller than the diameters of the inner circle of the shock absorber bearing of the armored vehicle and the cantilever shaft hole. By utilizing the auxiliary guide pin, the problems that the shaft is directly penetrated through a pin shaft in the prior art and not only is difficult to penetrate, but also the finish machining surface of the shaft is abraded, and the thread at the front end of the pin shaft is easily damaged are solved, in addition, the problem that the shaft end with a step is easily clamped on a contact end face is also solved, the assembly efficiency is improved, the quality is ensured, and the labor intensity is reduced.

Disclosure of Invention

The utility model aims at providing a supplementary round pin that draws that is used for two mechanical component cooperation to connect, it can insert two mechanical component's the through-shaft hole with the connecting pin axle fast downthehole, improves assembly efficiency to take out the connecting pin axle in the through-shaft hole of two mechanical component after the convenience.

A supplementary round pin that draws that is used for two mechanical component cooperations to connect, including drawing the round pin body, characterized by: the guide pin body is a round rod with one end diameter larger than the other end diameter, a hexagonal structure is arranged at the large end of the guide pin body, and a screw rod is arranged at the center of the hexagonal structure.

Further, the guide pin body, the screw and the hexagonal structure are integrated.

Furthermore, the screw rod is connected with an internal thread arranged at one end of a connecting pin shaft used for connecting the two mechanical components in a matching way.

Compared with the prior art, the utility model has the following advantage:

because the guide pin body has the tapering, can be quick get into two mechanical component corresponding wear the axle hole in, with the connecting pin axle of guide pin body coupling also quick get into two mechanical component corresponding wear the axle hole in, assembly efficiency is higher.

Because one end of the connecting pin shaft is provided with the internal thread hole, a condition is provided for the connecting pin shaft to be better taken out from the shaft penetrating holes corresponding to the two mechanical components.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 5, an auxiliary pin for the mating connection of two mechanical components includes a pin body 7, which is characterized in that: the guide pin body 7 is a round rod with one end diameter larger than the other end diameter, a hexagonal structure 72 is arranged at the large end of the guide pin body 7, and a screw rod 71 is arranged at the center of the hexagonal structure 72. A hexagonal structure is provided between the large end of the guide pin body and the screw to facilitate rotation of the screw using a wrench.

The pin body 7, the screw 71 and the hexagonal structure 72 are integrated.

Referring to fig. 6, the screw 71 is engaged with an internal thread formed at one end of a connecting pin 8 for connecting two mechanical members.

When in use, the internal thread at one end of the connecting pin shaft 8 is matched and connected with the external thread at the other end of the screw rod 71; the small end of the guide pin body 7 is inserted into the shaft penetrating holes corresponding to the two mechanical components, and the guide pin body is a tapered round rod, so that the insertion is rapid and accurate, and the working efficiency is high; then knocking the other end of the connecting pin shaft 8 by using a copper bar to enable the connecting pin shaft 8 to penetrate through shaft penetrating holes corresponding to the two mechanical components; finally, the screw rod 71 is unscrewed to be in threaded connection with the connecting pin shaft 8, the guide pin body 7 is detached, and the connecting pin shaft 8 is left in the shaft penetrating holes corresponding to the two mechanical components.
