Description

Technical Field

[0001] The utility model is applied to the field of sensors, and particularly relates to a proximity sensor housing. Background Art

[0002] In industrial automation and mechanical equipment, proximity sensors, as important detection components, are widely used in fields such as position detection, object recognition, and motion control. Traditional proximity sensor housing designs often suffer from complex processing, inconvenient installation, poor sealing, and difficult maintenance. This is especially true in hydraulic systems, such as cylinder piston position detection, where the harsh working environment places higher demands on the sensor's pressure resistance, oil resistance, and sealing performance. Existing sensor housings often struggle to meet all of these requirements simultaneously, resulting in the sensor being easily damaged, reduced detection accuracy, and even affecting the stable operation of the entire hydraulic system. Therefore, based on the above issues, if a proximity sensor housing with a simple structure, easy processing, quick installation, and good sealing could be designed, this problem could be well resolved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a proximity sensor housing with a simple structure, convenient processing, quick installation and good sealing performance.

[0004] The technical solution adopted by the present invention is as follows: the present invention is a cylindrical structure with a deep hole provided inside. The bottom end of the deep hole is limited by an electromagnetic inductor, and the electromagnetic inductor is limited by the piston push rod in the oil cylinder. A mounting hole is provided in the end of the sensor housing away from the sensing surface. The mounting hole is limited by a core element, and the core element is limited by an external device. The sensor housing is provided with a hexagonal protrusion near the mounting hole, and the hexagonal protrusion is limited by a wrench tool. It can be seen that the sensor housing is a cylindrical structure, which is convenient for the processing and installation of the sensor housing. The sensor housing supports and limits the electromagnetic inductor and the core element, so that the position of the piston push rod in the piston can be detected. The hexagonal protrusion is limited by the wrench tool, and the present invention is disassembled and assembled on the oil cylinder by twisting the wrench.

[0005] Furthermore, threads are provided on both sides of the hexagonal protrusion, the left side of the hexagonal protrusion is a first thread, and the right side of the hexagonal protrusion is a second thread. The first thread cooperates with the external sealing cover thread, and the second thread cooperates with the cylinder thread.

[0006] Furthermore, the deep hole and the mounting hole are coaxial, and the diameter of the mounting hole is larger than the diameter of the deep hole.

[0007] Furthermore, the hexagonal protrusion is integrally formed on the sensor housing.

[0008] Furthermore, a groove is provided on the right side of the hexagonal protrusion, a sealing ring is provided in the groove, and the sealing ring is sealed with the oil cylinder.

[0009] Furthermore, the first thread is an internal screw and the second thread is an external thread.

[0011] Figure 1 It is a structural view of the utility model;

[0012] Figure 2 It is a structural sectional view of the present utility model. DETAILED DESCRIPTION

[0013] like Figures 1 to 2 As described, in this embodiment, the utility model is a cylindrical structure, and a deep hole 1 is provided inside it. The bottom end of the deep hole 1 is limited by the electromagnetic inductor, and the electromagnetic inductor is matched with the piston push rod in the oil cylinder. A mounting hole 10 is provided in the end of the sensor housing away from the sensing surface. The mounting hole 10 is limited by a core element, and the core element is limited by an external device. The sensor housing is provided with a hexagonal protrusion 2 near the mounting hole 10, and the hexagonal protrusion 2 is limited by a wrench tool. It can be seen that the sensor housing is a cylindrical structure, which is convenient for the processing and installation of the sensor housing. The sensor housing supports and limits the electromagnetic inductor and the core element, so that the position of the piston push rod in the piston can be detected. The hexagonal protrusion 2 is limited by the wrench tool, and the utility model is disassembled and assembled on the oil cylinder by twisting the wrench.

[0014] like Figure 1 and Figure 2 In this embodiment, the hexagonal projection 2 is threaded on both its left and right sides. The left side of the hexagonal projection 2 is a first thread 3, and the right side of the hexagonal projection 2 is a second thread 4. The first thread 3 mates with the external sealing cover thread, while the second thread 4 mates with the oil cylinder thread. Thus, the first thread 3 connects the sensor housing to external equipment and also protects the ferrule element and electromagnetic sensor inside. The second thread 4 connects the sensor housing to the oil cylinder and ensures the oil cylinder's sealing, allowing it to function properly.

[0015] like Figure 2In this embodiment, the deep hole 1 and the mounting hole 10 are coaxial, and the diameter of the mounting hole 10 is larger than the diameter of the deep hole 1. Therefore, for ease of processing, the mounting hole 10 is machined further from the deep hole 1. Furthermore, the diameter of the mounting hole 10 is larger than the diameter of the deep hole 1, so that the ferrule element is limitedly engaged with the bottom of the mounting hole 10, and the mounting hole 10 serves to limit the position of the ferrule element.

[0016] like Figure 1 and Figure 2 In this embodiment, the hexagonal protrusion 2 is integrally formed on the sensor housing. This can be seen that integral molding can reduce processing steps, thereby reducing production costs, while ensuring material strength and avoiding the sealing cost of the sensor housing caused by components.

[0017] like Figure 2 As mentioned above, in this embodiment, a groove 5 is provided on the right side of the hexagonal protrusion 2, and a sealing ring is provided in the groove 5, which is in sealed engagement with the oil cylinder. It can be seen that the groove 5 supports and limits the sealing ring, and the sealing ring and the second thread 4 respectively engage with the oil cylinder to ensure the sealing of the oil cylinder, allowing the oil cylinder to function normally.

[0018] like Figure 2 In this embodiment, the first thread 3 is an internal thread, and the second thread 4 is an external thread. Thus, the first thread 3 is an internal thread, which cooperates with the external thread of the external sealing cover to connect the sensor housing to the external device, while also protecting the ferrule element and the electromagnetic inductor inside. The second thread 4 is an external thread, which cooperates with the internal thread of the oil cylinder to connect the sensor housing to the oil cylinder, while ensuring the oil cylinder's sealing and allowing the oil cylinder to function normally.

[0019] like Figure 2 In this embodiment, the second thread 4 and the first thread 3 are both provided with a tool withdrawal groove at positions close to the hexagonal protrusion 2. Thus, the tool withdrawal groove plays a role in tool withdrawal for the second thread 4 and the first thread 3 during machining.

[0020] In this embodiment, the working principle of the utility model is as follows:

[0021] like Figures 1 to 2 As shown, the insert element in the sensor housing is connected to the external device, and then the sensor housing is fitted into the oil cylinder through the second thread 4 and tightened by a wrench tool, and then the sensor housing is fitted with the external sealing cover thread through the first thread 3, and the cycle is repeated.

[0022] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
