Description

Technical Field

[0001] The utility model relates to the technical field of proximity switches, in particular to a proximity switch with a fine-tuning mechanism. Background Art

[0002] A proximity switch is a commonly used electronic sensor used to detect the approach or distance of an object. It works on different principles to trigger corresponding operations when an object approaches. Common types of proximity switches include inductive proximity switches, photoelectric proximity switches, capacitive proximity switches, and magnetic proximity switches. They are widely used in automation, mechanical control, and safety systems.

[0003] Proximity switches are often used as handover signals between processes on industrial production lines. When the sensing object passes through the proximity switch, the next process is started. During use, the proximity switch has its own optimal sensing distance. A distance greater than or less than this distance will affect the sensing effect of the proximity switch. After installation, it is not easy to adjust the optimal sensing distance of traditional proximity switches in a timely manner.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-6 As shown, the utility model provides a technical solution: a proximity switch with a fine-tuning mechanism, comprising a mounting seat 1, a positioning rod 2, a rotating ring seat 4, an adjusting rod 5, a telescopic seat 6 and a socket 7, mounting holes 11 are provided at four corners of the surface of the mounting seat 1, internal threaded holes 12 are symmetrically provided on the left and right sides of the center hole of the mounting seat 1, the internal threads of the internal threaded holes 12 are connected with the positioning rod 2, support plates 3 are symmetrically provided on the upper and lower sides of the center hole of the mounting seat 1, a rotating ring seat 4 is movably connected between the support plates 3, an adjusting rod 5 is rotatably connected to one side of the rotating ring seat 4, a telescopic seat 6 is provided inside the rotating ring seat 4, a socket 7 is provided on the front surface of the telescopic seat 6, and a proximity switch 8 runs through the telescopic seat 6.

[0026] Furthermore, one end of the positioning rod 2 is fixedly connected to a hexagonal cap 21, and the other end of the positioning rod 2 passes through the mounting seat 1 and is fixedly connected to a ball cap 22, so that the ball cap 22 can better contact the back of the rotating ring seat 4, and the positioning rod 2 can be used to adjust the distance between the left and right ends of the rotating ring seat 4 and the mounting seat 1;

[0027] It should be noted that: the surface of the positioning rod 2 is provided with threads matching the internal threaded hole 12 .

[0028] Furthermore, a rotating shaft 41 is symmetrically arranged on the upper and lower sides of the rotating ring seat 4, and the other end of the rotating shaft 41 is installed on the inner side of the support plate 3, and a torsion spring 42 is installed on the outer side of the rotating shaft 41, and the two ends of the torsion spring 42 are respectively installed on the surfaces of the rotating ring seat 4 and the support plate 3. Through the setting of the torsion spring 42, the rotating ring seat 4 can still maintain a tendency to rotate in the reverse direction when it is pushed by the positioning rod 2 on one side to rotate around the rotating shaft 41 as the center.

[0029] Embodiment 2

[0030] See also Figure 3-6 As shown, compared with Example 1, as another implementation of the utility model, one end of the adjusting rod 5 is fixedly connected to the hexagonal cap 2 51, and the other end of the adjusting rod 5 passes through the rotating ring seat 4 and is installed with a gear 52. Through the setting of the adjusting rod 5, the extension distance of the telescopic seat 6 can be adjusted.

[0031] Furthermore, a rectangular groove 61 is provided on one side of the telescopic seat 6, a rack 62 is provided on the top of the inner wall of the rectangular groove 61, and T-shaped grooves 63 are evenly provided on the front surface of the telescopic seat 6. The cross-sectional dimensions of the telescopic seat 6 match the cross-sectional dimensions of the inner through hole of the rotating ring seat 4, and the gear 52 is located inside the rectangular groove 61. The telescopic seat 6 is the direct load of the proximity switch 8. The extension distance of the telescopic seat 6, that is, the extension distance of the proximity switch 8, is determined by the cooperation of the gear 52 and the rack 62.

[0032] Furthermore, the socket 7 is rotatably connected to the inside of the T-slot 63 through a damping shaft 71, and a scale plate 73 is telescopically connected to the inside of the socket 7 through a spring 72, and a round head cap 74 is provided at the other end of the scale plate 73. Through the provision of the round head cap 74, it can better contact with the detection object;

[0033] It should be noted that the surface of the scale plate 73 marks the best working position of the proximity switch 8, and the distance from the front surface of the proximity switch 8 to the front surface of the telescopic seat 6 is equal to the farthest distance between the socket 7 and the telescopic seat 6.

[0034] Working principle: When in use, the first step is to install the mounting base 1 through the mounting hole 11 vertically and horizontally at the sensing position. The second step is to pull the socket 7 out from the inside of the T-slot 63. The third step is to rotate the hexagonal cap 51 through the hexagonal socket to drive the adjustment rod 5 to rotate inside the rotating ring base 4. Then, through the cooperation of the gear 52 and the rack 62, the telescopic base 6 is extended from the rotating ring base 4 until the round head cap 74 on one side contacts the sensing object. At the same time, the scale plate 73 moves inward to the optimal sensing distance mark. Note: In the fourth step, the hexagonal cap 21 on the other side is rotated by the hexagonal socket to drive the positioning rod 2 on the other side to rotate, so that the rotating ring seat 4 rotates about the rotating axis 41 until the round head cap 74 on the other side also contacts the sensing object. At the same time, the scale plate 73 on the other side moves inward to the best sensing distance marking point. In the fifth step, the other hexagonal cap 21 is rotated by the hexagonal socket to make the ball cap 22 contact the rotating ring seat 4. In the sixth step, the socket 7 is placed in the T-slot 63. This completes the fine-tuning process of the proximity switch.

[0035] It should be noted that: assuming that the left round head cap 74 contacts the sensing object first, then rotate the right positioning rod 2 so that the right round head cap 74 also contacts the sensing object, and finally, rotate the left positioning rod 2 to lock the balance state of the rotating ring seat 4 to prevent the elastic force of the torsion spring 42 from causing the rotating ring seat 4 to shake.
