Abstract

The invention provides a double-pin positioning mechanism, which comprises a bottom plate, a fixed pin, a movable pin, a screw bolt A and a screw bolt B, wherein a round hole and a waist-shaped hole are arranged on the bottom plate, threaded through holes are arranged in the fixed pin and the movable pin, a screw rod of the screw bolt A passes through the round hole arranged on the bottom plate and is positioned in the threaded holes of the fixed pin, and a screw rod of the screw bolt B passes through the waist-shaped hole arranged on the bottom plate and is positioned in the threaded holes of the movable pin. The double-pin positioning mechanism has the beneficial effects that the principle of double-pin positioning at one side is utilized, the positioning requirements of various parts are simultaneously met through changing the fixing distance of two pins and replacing the pins in different sizes, and the production cost is reduced.

Description

Two pin retention mechanisms
Technical field
The invention belongs to the positioning link technical field, be specifically related to a kind of pair of pin retention mechanisms.
Background technology
At component of machine; In particularly box parts processing, the assembling; Usually utilization plane and two pits positioning principle carries out the location of parts when processing, assembling; The unadjustable two pin distances of common plane and two pits detent mechanism; Then the common plane and two pits of cover mechanism can only be applied to a kind of processing, assembling of parts, and then different parts processing, assembling need the plane and two pits mechanisms of overlapping to accomplish more.
Summary of the invention
The purpose of this invention is to provide a kind of pair of pin retention mechanisms, can not regulate the problem of two pin distances to overcome existing plane and two pits detent mechanism.
The technical scheme that the present invention adopted is that a kind of pair of pin retention mechanisms comprises base plate, steady pin, moving pin, bolt A and bolt B; Base plate is provided with circular hole and mounting hole; Be provided with tapped through hole in steady pin and the moving pin; The screw rod of bolt A passes the screwed hole that circular hole on the base plate is positioned at steady pin, and the screw rod of bolt B passes the screwed hole that mounting hole on the base plate is positioned at moving pin.
Beneficial effect of the present invention, utilization plane and two pits positioning principle through changing the pin of fixing distance of two pins and replacing different size, satisfies multiple position components requirement simultaneously, improves production cost.
Description of drawings
Fig. 1 is the structural representation of the two pin retention mechanisms of the present invention;
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure, 1. steady pin, 2. bolt A, 3. mounting hole, 4. base plate, 5. moving pin, 6. bolt B.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
As depicted in figs. 1 and 2, the present invention provides a kind of pair of pin retention mechanisms, comprises base plate 4, steady pin 1, moving pin 5, bolt A2 and bolt B 6; Base plate 4 is provided with circular hole and mounting hole 3; Be provided with tapped through hole in steady pin 1 and the moving pin 5; The screw rod of bolt A2 passes the screwed hole that circular hole on the base plate 4 is positioned at steady pin 1, and the screw rod of bolt B 6 passes the screwed hole that mounting hole 3 on the base plate 4 is positioned at moving pin 5.
During use; The circular hole that the screw rod of bolt A2 passes on the base plate 4 is tightened in the screwed hole of steady pin 1; Orientation distance needs during for different parts processing, assembling; Moved horizontally the position of moving pin 5 along mounting hole 3, the mounting hole 3 that the screw rod of bolt B 6 passes on the base plate 4 is tightened in the screwed hole of moving pin 5.
Because the dimensions of required alignment pin is different when different parts processing, assembling; The pin that can corresponding replacing has threaded central aperture; Promptly change steady pin 1 and moving pin 5; And through regulating moving pin and steady pin distance; Location, the connection of completion when different parts are used the processing of plane and two pits formula, assembling and positioning; Adjustable pair of pin retention mechanisms of the present invention can realize the order ground that parts carried out flexible positioning, connection under the parts plane and two pits formula locate mode reducing production costs.
