Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with specific embodiments.

[0016] The structure of a ratchet wheel small included angle positioning device with V-shaped positioning groove with adjustable force value provided by the present invention is as follows figure 1 As shown, it includes a ratchet wheel 1 installed on the main shaft 2 and two positioning components 3. The ratchet wheel 1 can rotate around the Y axis shown in the figure. There are several V-shaped positioning grooves alternately distributed on both sides of the circumference of the ratchet wheel 1. The positioning components 3 are respectively installed on the brackets 4 on both sides of the ratchet wheel 1, such as figure 2 As shown, a rotation stop pin 5 is installed on the bracket 4 to limit the rotation of the positioning pin 7 around the X axis. The positioning block 6 of the positioning assembly 3 is sequentially installed with a positioning pin 7, a spring 8 and a positi...

Abstract

The small-angle ratchet positioning device with adjustable force value and V-shaped positioning groove disclosed by the present invention includes a ratchet and a positioning assembly, V-shaped positioning grooves are alternately distributed on the circumference of the ratchet, and positioning pins, springs and positioning The nut and the positioning pin are in contact with the circumferential surface of the ratchet under the pressure of the spring, and the two positioning pins are successively located in different V-shaped positioning grooves arranged on the circumference of the ratchet, and the elastic deformation degree of the spring is adjusted by rotating the positioning nut. The V-shaped positioning groove realizes the precise positioning of the small included angle on the circumference of the ratchet wheel, and alleviates the positioning interference; by adjusting the positioning nut on the positioning component, the working load of the spring is changed, and then the force between the positioning pin and the ratchet wheel is adjusted to realize the operation. Accurate adjustment of the force value; when the positioning pin is applied to the ratchet positioning force or damping force, the position of the positioning pin and the ratchet is different, which slows down the wear of the two, and the wear of the arc at the tip of the positioning pin is not Affect the realization of positioning function.

Description

Technical field [0001] The invention belongs to the technical field of locomotive console electrical appliances, and particularly relates to a small included angle ratchet positioning device with a V-shaped positioning groove with adjustable force value. Background technique [0002] The positioning device is widely used in various mechanical equipment, and is used to lock some important positions of the mechanism during operation. Due to the simple structure and clear and reliable positioning of the ratchet wheel positioning device, it is widely used in some control equipment, such as the control panel electrical appliances of the locomotive. The control handle needs to accurately position each gear on the circumference of the rotating shaft, in order to meet the various operations of the locomotive. At the same time, it satisfies the space restriction of the positioning device, which requires that the positioning device should be compact in structure, accurate and reliable in p...
