Description

Technical Field

[0001] The utility model relates to the field of oil cylinders, in particular to an induction oil cylinder. Background Art

[0002] The existing oil cylinder is composed of a cylinder barrel, a front cover, a rear cover, a piston, a piston rod and a seal. Under the premise of the current high requirements of high quality and high performance in the new energy industry, when improving the indicators of silicon steel sheet stators and rotors in the mold production, in order to ensure the flatness, verticality and performance of the products, a hydraulic oil cylinder will be added to the blanking position of the mold product to support the product. Ordinary oil cylinders do not have an induction stop function, which results in the product being unable to stop ejecting the mold due to excessive cylinder force, damaging the product and mold, and affecting production.

[0003] To this end, those skilled in the art have developed a hydraulic cylinder with a sensor. Summary of the invention

[0004] The utility model aims to provide an induction oil cylinder which has a simple structure and is easy to assemble.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an induction oil cylinder, including a cylinder body, a piston rod and a sensor; the piston rod is movably connected to the cylinder body, and the sensor passes through the cylinder body and the piston rod in sequence; the cylinder body is provided with a first channel, and the piston rod is provided with a second channel, and the first channel is connected to the second channel; the sensor includes a sensor connecting wire and a sensing head, the sensing head is connected to one end of the sensor connecting wire, the sensing head is screwed to the cylinder body, and the sensor connecting wire passes through the first channel and the second channel in sequence.

[0006] Compared with the prior art, the advantages of the utility model are: the induction cylinder adopts a simple structural design, consisting of a cylinder body, a piston rod and a sensor. This simple structure makes the manufacturing and assembly process easier and reduces production costs. Due to the simple structure of the induction cylinder, the assembly process becomes simpler. The movable connection between the piston rod and the cylinder body and the installation of the sensor are relatively easy, without the need for complex tools or professional techniques, thereby improving assembly efficiency. The sensor is installed by penetrating the cylinder body and the piston rod, ensuring the accurate position of the sensor. This helps the sensor to accurately detect and sense the state and movement of the cylinder and provide accurate feedback information. The cylinder body and the piston rod of the induction cylinder are respectively provided with a first channel and a second channel, and the two channels are connected, so that the sensor can penetrate the cylinder body and the piston rod.

[0007] In some embodiments of the present invention, there is a first step between the sensing head and the sensor connecting wire, and a second step is provided in the first channel. This design can increase the connection stability between the sensing head and the sensor connecting wire and prevent them from loosening or falling off.

[0008] In some embodiments of the utility model, the sensor head is provided with a locking nut. The locking nut can be used to fasten the sensor head and fix it on the cylinder body to prevent it from loosening or falling off. In addition, the position height of the sensor can be adjusted by the nut.

[0009] In some embodiments of the present invention, the length of the cylinder body ranges from 40 cm to 60 cm.

[0010] In some embodiments of the present invention, the length of the piston rod ranges from 30 cm to 60 cm.
