Reactive arm for mechanical control

Abstract

The invention provides a reaction arm for mechanical control, comprising an arm body, a connecting rod and a fixed rod, wherein the arm body comprises a first sub arm and a second sub arm sleeved witheach other, the second sub arm is fixedly connected with the connecting rod, a support table is arranged at the inner end of the second sub arm, a universal joint is arranged on the support table, the support table is connected with a telescopic rod through the universal joint, a contact table is arranged at the end of the telescopic rod, a contact is arranged on the contact table, the first subarm is hollowed, the hollowed position corresponds to the contact, and the connecting rod is connected with the fixed rod through a spherical connector. According to the reaction arm for mechanical control, the first sub arm and the second sub arm are sleeved with each other, so that the overall length of the arm body can be adjusted, and the reaction arm can adapt to more use environments. The contact is arranged inside the arm body, so that only one contact is exposed when the reaction arm works, and inadvertent contact caused by simultaneous exposure of a few contacts is prevented. The armbody is driven by the spherical connector to rotate, so that the movement stroke direction of the arm body can be enlarged.

Description

technical field [0001] The invention belongs to the technical field of mechanical connectors, and in particular relates to a reaction arm for mechanical control. Background technique [0002] At present, in the field of mechanical control, it is usually controlled by hydraulic equipment. At present, it is very difficult for the hydraulic equipment to accurately control the stroke of the hydraulic piston, or the angle of the lever pushed by the piston stroke. It requires the operator to be quite familiar with the machinery and quite skilled. , there are also some foreign equipment that use electronics to accurately and quickly control their travel by computer methods. The cost is naturally very expensive and is not conducive to promotion. In the process of mechanical control, the reaction arm is an indispensable part. The reaction arm is usually Receive the action signal from the control arm, complete the action command sent by the control arm, and constantly touch the travel...

[0002] At present, in the field of mechanical control, it is usually controlled by hydraulic equipment. At present, it is very difficult for the hydraulic equipment to accurately control the stroke of the hydraulic piston, or the angle of the lever pushed by the piston stroke. It requires the operator to be quite familiar with the machinery and quite skilled. , there are also some foreign equipment that use electronics to accurately and quickly control their travel by computer methods. The cost is naturally very expensive and is not conducive to promotion. In the process of mechanical control, the reaction arm is an indispensable part. The reaction arm is usually Receive the action signal from the control arm, complete the action command sent by the control arm, and constantly touch the travel switch to complete the control of the working arm. However, the existing reaction arm usually only has two contacts and the stroke is fixed. If it is necessary to complete complex formation control, it is necessary to increase the number of reaction arms, and usually only one contact point of the reaction arm works, increasing the number of reaction arms will not only cause inconvenience in the control of the reaction arm, but also cause contact errors of the contact points of the reaction arm Case
