Description
Technical Field
The invention relates to a 360-degree limiting device capable of automatically resetting, which is used for a limiting shaft system doing rotary motion. The limitation that the 360-degree motion range of the limiting shaft system cannot be achieved in the past is overcome, and meanwhile the condition that manual reset is needed after limiting is triggered in the past is overcome.
Background
The rotary shaft provides a rotary motion to the tested product. When no collecting ring is installed in the rotating shaft system, the rotating shaft system should be prevented from making continuous motion so as to prevent the cables of the tested products from being twisted off. Such stops often combine electrical stops with mechanical stops. The electric limit adopts a mode that the photoelectric disc triggers the photoelectric switch, when the photoelectric disc triggers the photoelectric switch, the control system cuts off the driving power supply after receiving a signal of the photoelectric switch, and the shafting stops moving after losing the driving force. Therefore, after the limit is triggered and the shafting stops moving, the shafting (the photoelectric disc) is rotated to move to a non-limit area, and then the driving can be restarted. The mechanical limit of the conventional limit device can occupy the rotation space of the shaft system, so that the shaft system cannot realize 360-degree (full circle) rotation, and the electrical limit device is often reset manually when the shaft system triggers the limit. For a rotating shaft system which needs to realize 360 degrees (full circle) or cannot realize manual reset, the conventional limiting cannot meet the requirement. The invention overcomes the defect of conventional limit.
Disclosure of Invention
The invention aims to provide a 360-degree limiting device capable of automatically resetting, and the device reasonably and effectively solves the problems that a conventional limiting device occupies the rotation space of a shaft system, the shaft system cannot realize 360-degree (full circle) rotation, and manual resetting is often needed when the shaft system triggers limiting.
The invention adopts the following technical scheme:
the utility model provides a 360 degrees stop device that can automatic re-setting, includes that fixed plate, photoelectric support, photoelectric switch, spout bottom plate, spout, removal hit the piece, photoelectricity dish, spring, rotation hit the piece, the rotation is changeed the spiale, its characterized in that:
1. the rotary collision block is arranged on the rotary connecting shaft, and the rotary connecting shaft is connected to the rotary shaft system. The rotating shaft system is generally driven by a motor and controlled by a control system to do rotary motion. The above constitutes the turning part of the limiting device.
2. The sliding groove and the sliding groove bottom plate are arranged on the fixing plate, the movable collision block can move in the sliding groove, and the photoelectric disc is arranged on the movable collision block and moves along with the movable collision block. The movable collision block is designed into a shape of T, and two transverse sides of the movable collision block are respectively provided with a spring. The photoelectric switch is arranged on the photoelectric bracket, the photoelectric bracket and the photoelectric switch are arranged on the outer side of the sliding chute, and the photoelectric bracket and the photoelectric switch are symmetrically separated from the transverse symmetrical center of the sliding chute at a certain distance and are fixed on the fixing plate. The fixed plate is generally mounted on a base on which the rotary shaft does not move. The rotary motion limiting part of the limiting device is formed.
3. The rotation shaft system drives the rotation connecting shaft and the rotation collision block to do rotary motion, and the rotation shaft system does not touch the rotation limiting part in a 350-degree range (the range is that a plane where a transverse symmetry center of the sliding chute is located is taken as a symmetry plane, and a rotation center is taken as a center, namely +/-175 degrees).
4. When the range of motion exceeds 350 °, the rotary striker may approach and hit the moving striker from one side (determined by the direction of motion). When the movement is continued to exceed 5 degrees, the photoelectric disc on the moving collision block triggers the photoelectric switch, and the spring on the side of the moving collision block is also in a compressed state. At the moment, the control system receives the photoelectric switch signal and disconnects the driving power supply. The rotating shaft system loses driving and stops moving. The movable collision block and the photoelectric disc on the movable collision block return to the central non-triggering limit position under the restoring force of the spring, and the rotary collision block drives the rotary shaft system to return to the non-triggering limit position which is initially contacted with the movable collision block. At which point the control system will regain the ability to drive the rotating shafting. In the same way, when the rotary collision block approaches from the other side and collides with the movable collision block, the same situation also occurs, namely, the rotation shaft system realizes the full-circle rotation within the rotation range of 0-360 degrees or +/-180 degrees, and the limiting device can realize automatic reset.
5. When the rotating shaft system triggers the electrical limit and does not stop in time, the rotating collision block continues to push the moving collision block to move for a short distance until the moving collision block collides with the side wall of the sliding chute and stops. At the moment, the spring on the movable collision block is in a large compression state, the principle is consistent with that of 4, and the movable collision block returns to the central non-triggering limiting position under the action of the restoring force of the spring. Thereby realizing mechanical limit.
The beneficial technical effects of the invention are as follows:
the invention discloses a 360-degree limiting device capable of automatically resetting, which reasonably and effectively solves the problems that a conventional limiting device occupies the rotation space of a shaft system, the shaft system cannot realize 360-degree (full circle) rotation, and manual resetting is often needed when the shaft system triggers limiting.
