Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the drawings and embodiments:

[0014] Such as figure 1 As shown, a weight anti-swing gap clamping mechanism for a small torque standard device mainly includes: clamping pliers 1, pin 2, spring 3, base 4, bearing 5, bearing frame 6 and linear motion drive mechanism 7 .

[0015] The clamping forceps 1 is divided into left and right lobes, the two lobes have the same structure and are placed symmetrically. There is a connecting through hole in the middle to allow the pin 2 to pass through. The pin 2 is fixedly connected with the bottom base 4. At the same time, the pin 2 is used as a fulcrum, and the two parts of the clamping pliers 1 can rotate around the pin. An arc-shaped spring 3 passes through the middle part of the clamp 1. The spring 3 gives an inward pressing force to the tail of the clamping pliers, so that the front end of the clamping pliers 1 is in an open state when it is not a...

Abstract

The invention relates to a weight swing prevention gap clamping mechanism for a small-torque standard device. The weight swing prevention gap clamping mechanism for the small-torque standard device comprises a clamping jaw, a hinge pin, a spring, a base, a bearing, a bearing bracket and a linear motion driving mechanism. The clamping jaw is connected to the upper face of the front of the base through the hinge pin, the linear motion driving mechanism is connected to the upper face of the rear of the base through the bearing bracket, the front end of the bearing bracket is connected with the bearing, the clamping jaw is divided into a left part and a right part, a through hole connected with a weight placement frame is formed in the front of the clamping jaw, the arc-shaped spring penetrates through the middle of the clamping jaw, and a step structure is arranged on the tail portion of the clamping jaw. With the weight swing prevention gap clamping mechanism for the small-torque standard device, the weight and weight frame swing problems can be solved; through the automation technology, the device can be clamped automatically; adjustment in the two states of clamping and loosening can be freely achieved through the jaw type clamping mechanism.

Description

Technical field [0001] The invention relates to a small torque standard device, in particular to a weight anti-swing gap clamping mechanism for a small torque standard device. Background technique [0002] The deadweight torque standard device uses the weight of the weight as the standard force value, directly or after being amplified by a certain lever mechanism, the standard torque is generated through the action of the lever arm. The static-weight torque standard device requires the weight and the weight placement rack to remain stable during the weight loading or unloading process to ensure that the weight can be loaded in the correct position or unloaded in the correct position. As for the small torque standard device, due to its very small weight, the freely swingable weight holder hanging on the main beam is extremely susceptible to the influence of the surrounding environment. Small amounts of sound waves and airflow can cause the weight holder to shake , It is difficult...
