Description

Technical Field

[0001] The utility model belongs to the field of electrical and automation control and relates to a proximity switch sensing distance positioning tool. Background Art

[0002] In the process of automatic control, the movement of the equipment is often controlled by proximity switches (non-contact position sensors). This type of switch is an ideal electronic switch sensor. When the metal detector approaches the sensing area of ​​the switch, the electromagnetic induction controls the internal contact action to transmit the electrical signal. The switch can quickly issue electrical instructions without contact, pressure, or sparks, accurately reflecting the position and stroke of the moving mechanism. Since there is no direct mechanical contact between the moving parts and the sensor during the control process, it is completely controlled by electromagnetic induction at a certain distance. The distance between the moving parts (metal detectors) and the sensor becomes the key to effective control. The sensing distance is often displaced due to the frequent movement and vibration of the mechanical equipment, resulting in the inability of the proximity switch and the moving parts to be accurately and effectively controlled at the appropriate position and distance. The factors that affect the sensing position and distance between the proximity switch and the moving parts are: ① the looseness and displacement of the proximity switch itself, ② the displacement of the sensing parts in the horizontal, vertical, and front-to-back directions; but the existing tools cannot quickly locate the sensing distance of the sensor, so it is urgent to design corresponding tools. Utility Model Content

[0005] Optionally, the distance detection tool has a size of 100×20×8 mm.

[0006] The beneficial effect of the utility model is that: based on the summary of previous sensor signal failures, the utility model invents and creates practical and effective auxiliary devices, making the installation and daily inspection of non-contact position sensors more convenient and efficient, and greatly reducing equipment failures caused by installation position and distance problems of such sensors.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0016] See also Figure 1 to Figure 3 It is a proximity switch sensing distance positioning tool, which is mainly composed of two tools: a mounting base 1 and a distance detection tool. The two are interdependent and coordinated to jointly complete the effective positioning of the sensor sensing distance. It is a tool that can effectively reduce the sensor sensing distance deviation.

[0017] 1. Base (such as Figure 2 ): Made of iron material, with an inner hole 11 in the center, it has reliable rigidity and easy welding characteristics, can effectively withstand external forces and is easy to weld and fix on site. The manufactured base has uniform specifications, consistent dimensions, and a flat surface. The proximity switch is flexibly adjustable in the inner hole 11 of the base, and the proximity switch locking nut is in effective contact with the surface of the base and is firmly fastened, which can effectively solve the problems of unstable sensor installation, unreliable locking, and easy loosening and displacement in the early stage.

[0018] 2. Distance detection tool 2 (such as Figure 3 ): Made of FR4 epoxy board, it has stable physical properties such as insulation, high hardness, wear resistance, high temperature resistance, corrosion resistance, and easy cutting. According to the specifications and characteristics of the proximity switches used in Chongqing Iron and Steel Blast Furnace, a standard sensing distance of 8mm is uniformly formulated. The epoxy board material is used to make a 100×20×8mm long strip tool with a hole at the tail end for roping. The whole tool is small and flexible, easy to carry and convenient to use. When the proximity switch is newly installed or the daily distance check after installation, the strip tool is inserted into the gap between the proximity switch and the sensing component to quickly and effectively detect whether the sensing distance meets the standard. The combined use of the above two tools can effectively locate the sensing distance of the proximity switch, and is also convenient for sustainable regular detection in the later stage, solving the problem of frequent signal failures caused by the displacement of the proximity switch itself and the sensing distance not meeting the standard in the early stage.

[0019] The utility model aims to prevent malfunctions (signal flicker, no signal, etc.) or accidents (causing blast furnace wind stoppage or slow wind) caused by the installation of a proximity switch or changes in the sensing position and distance after installation.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
