Abstract
Description
Technical Field
[0001] The utility model relates to the field of encoders, in particular to an oil-proof device for a wire-drawing encoder. Background Art
[0002] Aluminum processing sites often require the use of lifting platforms, and the lifting height of the lifting platform is detected in real time by the wire encoder. Since the air at the processing site contains a lot of oil and gas, the wire of the wire encoder will bring oil and gas into the wire box during the pulling and contraction process. Long-term use will cause oil to form in the wire box, and the oil will enter the encoder through the main shaft of the encoder, thereby affecting the normal operation of the encoder and the detection accuracy. Utility Model Content
[0003] In view of this, the purpose of the utility model is to provide an oil-proof device for a wire-drawing encoder with novel structure, strong practicality and good oil-proof effect, which can separate and prevent oil from entering the encoder body.
[0004] The utility model is implemented by the following scheme: an oil-proof device of a wire-drawing encoder, comprising a wire-drawing box and an encoder body, wherein the wire-drawing box and the encoder body are connected via an oil-proof casing, and the main shaft of the encoder body passes through the oil-proof casing and is connected to a rotating shaft in the wire-drawing box; a first sealing ring is provided between the side surface of the oil-proof casing and the front end face of the wire-drawing box, and a second sealing ring is provided between the rear end face of the oil-proof casing and the front end face of the encoder body.
[0005] Furthermore, the side of the wire draw box is connected with a plurality of pressing blocks distributed around the oil-proof casing by screws, the outer periphery of the front end of the oil-proof casing is provided with an annular groove, and the side of the pressing block is provided with a convex portion that is inserted into the annular groove.
[0006] Furthermore, a limiting hole adapted to the front end boss of the encoder body is provided at the middle position of the rear end of the oil-proof sleeve.
[0007] Furthermore, the side of the wire pull box is provided with a first annular sealing groove for installing a first sealing ring, the front end edge of the oil-proof sleeve is provided with a stepped groove matching the annular sealing groove; the rear end of the oil-proof sleeve is provided with a second annular sealing groove for installing a second sealing ring.
[0008] Furthermore, an oil retaining ring is sleeved on the main shaft of the encoder body.
[0009] Furthermore, an oil drain port is provided at the bottom of the oil-proof casing.
[0010] Compared with the prior art, the utility model has the following beneficial effects: the oil-proof device of the wire-drawing encoder of the utility model has a novel structure, a reasonable design, strong practicability and a good oil-proof effect. By adding an oil-proof sleeve between the wire-drawing box and the encoder body, the oil seeping from the wire-drawing box will enter the oil-proof sleeve instead of directly entering the encoder body, thereby playing the role of isolating and preventing oil from entering the encoder body.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0017] like Figure 1~2As shown, an oil-proof device for a wire-drawing encoder includes a wire-drawing box 100 and an encoder body 300, wherein the wire-drawing box and the encoder body are connected via an oil-proof casing 200, and the main shaft 310 of the encoder body 300 is connected to the rotating shaft in the wire-drawing box after passing through the oil-proof casing. The connection method between the main shaft and the rotating shaft in the wire-drawing box has not been changed, and the existing connection method is still adopted, except that the main shaft needs to pass through the oil-proof casing; a first sealing ring 110 is provided between the side surface of the oil-proof casing and the front end face of the wire-drawing box, and a second sealing ring 210 is provided between the rear end face of the oil-proof casing and the front end face of the encoder body. The arrangement of the two sealing rings can prevent oil and gas from the external environment from entering the interior, thereby improving the sealing performance. The utility model can increase the distance between the wire-drawing box and the encoder body by adding an oil-proof casing between the wire-drawing box and the encoder body, and the oil seeping from the wire-drawing box will enter the oil-proof casing instead of directly entering the encoder body, thereby playing the role of isolating and preventing oil from the encoder body.
[0018] In this embodiment, the side of the wire draw box 100 is connected to a plurality of pressure blocks 120 distributed around the oil-proof casing by screws, the outer periphery of the front end of the oil-proof casing 200 is provided with an annular groove 220, and the side of the pressure block is provided with a convex portion 121 that is inserted into the annular groove. When the screws are tightened to lock the pressure block, the pressure block can press and fix the oil-proof casing on the side of the wire draw box 100; when disassembling, the screws can be loosened and the pressure block can be rotated to make the convex portion withdraw from the annular groove, and the oil-proof casing can be removed.
[0019] In this embodiment, a limiting hole 230 adapted to the front end boss of the encoder body is provided at the middle position of the rear end of the oil-proof casing 200. The oil-proof casing and the encoder body are connected together by screws.
[0020] In this embodiment, the side of the wire pull box 100 is provided with a first annular sealing groove 130 for installing a first sealing ring, and the front end edge of the oil-proof casing 200 is provided with a stepped groove 240 that cooperates with the annular sealing groove; the rear end of the oil-proof casing is provided with a second annular sealing groove 250 for installing a second sealing ring.
[0021] In this embodiment, an oil retaining ring 320 is sleeved on the main shaft 310 of the encoder body, and the oil retaining ring has an oil retaining effect, which can prevent oil from entering the encoder body along the main shaft. As the distance between the encoder body and the wire drawing box becomes farther, when the original main shaft length of the encoder body is not enough, an extension shaft extending into the wire drawing box can be connected to the front end of the main shaft, and the oil retaining ring 320 can be set at the joint of the main shaft and the extension shaft, which can improve the coaxiality of the connection between the two.
[0022] In this embodiment, an oil drain port 260 is provided at the bottom of the oil-proof casing 200, and the oil drain port is used to drain the oil in the oil-proof casing. The oil drain port can be provided with a plug and opened regularly to drain the oil.
