Description

Angle-adjustable limiting component

Technical Field

The utility model belongs to the mechanism design field in the mechanical design field, concretely relates to spacing part of angularly adjustable.

Background

In the field of traditional mechanical design, especially in the field of mechanism design, the rotation angle of some rotating parts is often limited and adjusted to meet the requirement of the actual rotation range of a product. Generally, taking an inner frame of a photoelectric aiming device as an example, the range of the azimuth and the pitch angle of the inner frame is small, generally ranging from-6 degrees to +6 degrees, a limit component for limiting the rotation angle of the inner frame needs to be designed on a static support, and the span between the limits needs to meet the requirement of the angle range.

The existing limiting component generally adopts a structural mode of sleeving a ring-shaped rubber pad on a limiting shaft, the ring-shaped rubber pad can play a certain damping role, and the angle of the structure is fixed after installation, so that the structure does not have an angle fine adjustment function, and the requirements of production and processing cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model provides an angle can realize finely tuning, can realize the spacing part of shock-absorbing function that targets in place simultaneously, and the part of involving is simple, quantity and kind are few, and it is low with use cost to make.

In order to realize the above purpose, the utility model discloses the technical scheme who adopts is:

the utility model provides a spacing component with adjustable angle, which comprises a fixed pin, a fine tuning shaft, an elastic washer and an anti-collision ring; the fixing pins penetrate through the upper surface and the lower surface of the fine adjustment shaft from top to bottom; the fine tuning shaft and the fixing pin are eccentrically arranged; the elastic gasket is sleeved on the circumferential outer surface of the fine adjustment shaft, and the anti-collision ring is sleeved on the outer surface of the elastic gasket.

In order to avoid the separation of the elastic washer and ensure that the elastic washer has a deformation space, the angle-adjustable limiting component also comprises an upper end cover and a lower end cover, wherein the upper end cover is arranged on the fine adjustment shaft and the upper surface of the elastic washer through a fixing pin; the lower end cover is arranged on the lower surfaces of the fine tuning shaft and the elastic washer through fixing pins; the area of the upper end cover is larger than that of the upper surface of the fine adjustment shaft, and the area of the upper end cover is smaller than the sum of the areas of the fine adjustment shaft and the upper surface of the elastic washer; the area of the lower end cover is larger than that of the lower surface of the fine adjustment shaft, and the area of the lower end cover is smaller than the sum of the areas of the lower surfaces of the fine adjustment shaft and the elastic washer.

Preferably, the fixing pin is a bolt, a nut portion of the fixing pin is arranged above the upper end cover, and a screw portion sequentially penetrates through the upper end cover, the upper surface of the fine adjustment shaft and the lower surface of the fine adjustment shaft from top to bottom to close the lower end cover.

THE ADVANTAGES OF THE PRESENT INVENTION

The limiting component structure design mode capable of achieving the in-place damping function is simple in related parts, small in quantity and variety, low in manufacturing and using cost and capable of easily replacing traditional limiting components.

Detailed Description

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

The utility model provides a spacing component with adjustable angle in one embodiment, which comprises a fixed pin 1, a fine tuning shaft 2, an elastic washer 3 and an anti-collision ring 4; the fixing pin 1 penetrates through the upper surface and the lower surface of the fine adjustment shaft 2 from top to bottom; the fine tuning shaft 2 and the fixing pin 1 are eccentrically arranged; the elastic washer 3 is sleeved on the circumferential outer surface of the fine adjustment shaft 2, and the anti-collision ring 4 is sleeved on the outer surface of the elastic washer 3.

In one embodiment, in order to prevent the elastic washer 3 from being separated and ensure that the elastic washer 3 has a deformation space, the angle-adjustable limiting component further comprises an upper end cover 5 and a lower end cover 6, wherein the upper end cover 5 is mounted on the upper surfaces of the fine adjustment shaft 2 and the elastic washer 3 through a fixing pin 1; the lower end cover 6 is arranged on the lower surfaces of the fine adjustment shaft 2 and the elastic washer 3 through a fixing pin 1; the area of the upper end cover 5 is larger than that of the upper surface of the fine adjustment shaft 2, and the area of the upper end cover 5 is smaller than the sum of the areas of the fine adjustment shaft 2 and the upper surface of the elastic washer 3; the area of the lower end cover 6 is larger than that of the lower surface of the fine adjustment shaft 2, and the area of the lower end cover 6 is smaller than the sum of the areas of the lower surfaces of the fine adjustment shaft 2 and the elastic washer 3.

In one embodiment, the fixing pin 1 is a bolt, the nut portion of the fixing pin 1 is disposed above the upper end cap 5, and the screw portion sequentially passes through the upper end cap 5, the upper surface of the fine adjustment shaft 2, the lower surface of the fine adjustment shaft 2, and the lower end cap 6 from top to bottom.

The following is a description of the operation of the present invention.

As shown in fig. 3, the stopper is fixed to both sides of the rotating member by the fixing pins 1, and when the rotation angle of the rotating member needs to be finely adjusted, the fixing pins 1 are loosened to eccentrically rotate the fine adjustment shaft 2, the elastic washer 3, and the anti-collision ring 4 around the fixing pins 1, and then the fixing pins 1 are tightened to finely adjust the rotation angle of the rotating member.

When the rotating component rotates at an excessively high speed, the rotating component firstly collides against the anti-collision ring 4, then the stress is transmitted to the elastic washer 3 made of rubber, the elastic washer 3 generates elastic deformation to offset the stress, and the rotating component and the limiting component are protected.
