The detector 3 also includes a case 5, a pressure sensitive actuation membrane 6 inside the case, a movable contact 7 fixed to the membrane 6, a fixed contact 8 fixed to the case 5 below the movable contact 7, and both contacts. It is composed of a lead wire 9 that sends this as an electrical detection signal when it comes into electrical contact with the lead wire 9.

After the main body 1 made of an elastic material such as hard rubber is attached along the maximum outer diameter of the moving object B, the moving object B is caused to perform a predetermined work. If the moving object B comes into contact with an obstacle C due to abnormal movement due to some mistake during this work, the main body 1 will be compressed and a part of the sealed fluid will be transferred from one end of the main body 1 to the connecting pipe 2.
and flows into the detector 3. The contact points 7 and 8 in the detector 3 come into contact with each other due to the pressure of the inflowing fluid, which detects that the moving object B has come into contact with the obstacle C, and immediately sends a signal to the control unit of the moving object B, causing it to move. stop something.

できるという優れた効果がある。 As is clear from the above description, the present invention consists of a cylindrical main body made of an elastic material, the hollow part of which is sealed with a gas or liquid regulator, and a main body connected to one end of the main body via a connecting pipe made of an inelastic material. A detector is provided for detecting changes in fluid pressure enclosed in the main body, and the detector includes a case, a pressure-sensitive actuating membrane that expands and contracts in response to pressure changes within the case, and an electrically detectable sensor that detects when the pressure-sensitive actuating membrane expands. A braking device for a moving object to which the main body is attached is provided so as to be suddenly activated by the electrical detection signal. Therefore, the present invention has the excellent effect of automatically preventing a moving object, such as a spindle head of a machine tool, from colliding with an obstacle and being damaged.
