Problems solved by technology

Under the condition of relatively stable reciprocating motion of general mechanical equipment, the limit switch can meet the requirements of use, but occasionally due to the delay of the induction signal, or the abnormal control, the transmission mechanism will move slightly over-position, and the probe of the limit switch will be over-compressed, so the stroke is easy to be damaged. switch, even the transmission knot machine is locked due to excessive compression

Embodiment Construction

[0018] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] Such as figure 1 As shown, the terminal limit of the screw transmission device is often controlled by a travel switch. The travel switch is usually installed with a fixed baffle, and the motor 5 is started. The protruding probe of the travel switch 1 on the fixed baffle 2, when the probe is pressed into a certain depth, the controller receives the stop signal, controls the motor 5 to stop, and makes the telescopic rod 3 stop at the proper position.

[0020] However, occasionally due to the delay of the induction signal or abnormal control, the telescopic threaded rod 3 will not stop in time, a...

Abstract

The invention discloses an anti-delay collision device for a travel switch, and the device comprises a fixed support and a cylindrical housing. The fixed support and the cylindrical housing are coaxially arranged to form a sliding pair, and a spring is disposed between the fixed support and the cylindrical housing, so that the motion damping of the cylindrical housing is increased. The travel switch is fixedly installed in the cylindrical shell, and a gap exists between the end face of the side, provided with a probe, of the travel switch body and the outer bottom wall of the cylindrical housing. By adopting the anti-delay collision device with a certain fault tolerance function, the travel switch can be effectively fixed at a proper position, the travel switch cannot be damaged due to excessive collision, and meanwhile, a transmission mechanism cannot be locked due to excessive compression.

Description

technical field [0001] The invention relates to a limit device for controlling travel of electric components, in particular to a delayed collision prevention device for a travel switch. Background technique [0002] In mechanical transmission, travel switches are often required to limit the travel set by the mechanism. The limit switch is usually installed with a fixed baffle. The basic structure of the limit switch is that a protruding part of the transmission mechanism contacts the probe of the limit switch. When the probe is pressed into a certain depth, the controller receives the stop signal and controls the movement of the mechanism. Under the condition of relatively stable reciprocating motion of general mechanical equipment, the limit switch can meet the requirements of use, but occasionally due to the delay of the induction signal, or the abnormal control, the transmission mechanism will move slightly over-position, and the probe of the limit switch will be over-co...
