Problems solved by technology

[0002] In order to accurately control the position of the piston in the oil cylinder, a proximity switch is often set on the cylinder; the existing oil cylinder uses a proximity switch such as figure 1 As shown, the protective cover 8, the mounting base 9, and the probe 10 placed in the two, the position of the probe 10 in the axial direction is related to the accuracy of its detection. In order to control its axial position, two threads are provided on the probe 10. The adjustment nut 11, the lower adjustment nut is in contact with the installation base 9; the disadvantages of this structure are: 1) It is difficult to adjust the axial position of the probe 10 through the two adjustment nuts 11, which cannot be completed by non-professionals, and the interchangeability is also poor; 2) When the oil cylinder is subjected to high pressure, it will vibrate, the two adjusting nuts 11 are easy to loosen, and the position of the probe 10 is easy to change, so it is difficult to ensure normal operation; 3) The working status of the proximity switch cannot be displayed, and the operator cannot monitor the fault.

Abstract

The invention discloses a proximity switch for an oil cylinder. The proximity switch comprises a protective sleeve, a mounting base, a probe arranged in the protective sleeve and the mounting base, and a connecting line connected with the rear end of the probe. The proximity switch for the oil cylinder is characterized in that the protective sleeve is provided with a stepped hole; a shaft shoulder is arranged in the middle of the probe; the mounting base and the protective sleeve are connected through a thread and a radial set screw; the probe is located in inner holes of the protective sleeve and the mounting base; and the shaft shoulder of the probe is clamped between the end face of the stepped hole of the protective sleeve and the rear end face of the mounting base. The proximity switch for the oil cylinder has the advantages of being easy and convenient to mount, good in interchangeability, resistant to high pressure and not prone to loosening. The normal work can be guaranteed, and the working state of the proximity switch can be monitored.
