Description

Technical Field

[0001] The utility model belongs to the technical field of gas meter component installation, in particular to a grease spraying device for a gas meter sealing sleeve. Background Art

[0002] Before installing the cover plate on the top of the gas meter shell, it is necessary to install the sealing sleeve, vertical shaft sleeve and vertical shaft in the vertical shaft hole in sequence. After installing the sealing sleeve and vertical shaft sleeve, it is necessary to apply a layer of grease on the inner wall of the sealing sleeve to facilitate the installation of the vertical shaft through the sealing sleeve.

[0003] At present, the inner wall of the sealing sleeve is generally oiled by automated equipment. However, after the sealing sleeve and the vertical shaft sleeve are installed, the aperture of the vertical shaft hole is small. Although the oil injection pipe can be controlled to enter for oiling, the sealing sleeve or the vertical shaft sleeve is easily brought out when the oil injection pipe is taken out, thereby affecting the subsequent installation steps of the automated installation line.

[0023] Example

[0024] like Figure 1 and Figure 2 As shown;

[0025] A grease spraying device for a gas meter sealing sleeve, the grease spraying device is used in conjunction with a guide rail 1, the guide rail 1 has two, a movable plate 8 is movably placed on the guide rail 1, the movable plate 8 moves along the guide rail 1 by the drive of the guide rail 1, and the gas meter housing is fixed on the movable plate 8 by a fixing frame 82 on the movable plate 8. The grease spraying device comprises: a supporting mechanism, the supporting mechanism comprises two mounting frames 2, the mounting frames 2 are fixed on the outer side walls of the corresponding guide rails 1, and a top plate 3 is commonly installed on the two mounting frames 2; a driving mechanism is installed on the top plate 3, the driving mechanism comprises a telescopic member 6, the telescopic member 6 can be a cylinder, guide rods 4 are symmetrically arranged on the top plate 3, and a plurality of guide rods 4 are penetrated and installed with movable plates 5, and the telescopic member 6 is installed On the movable plate 5, the output end of the telescopic member 6 is fixedly connected to the top plate 3. After the telescopic member 6 is started to be telescoped, the movable plate 5 moves up and down along the guide rod 4; an oiling mechanism 7 is symmetrically installed on the movable plate 5, and the oiling mechanism 7 includes an oil pipe 71, which is connected to an external oil supply pump. The vertical shaft hole in the gas meter shell matches the oil pipe 71, and the oil pipe 71 can be inserted into the vertical shaft hole. Oil injection holes 72 are evenly opened on the outer periphery of the bottom of the oil pipe 71, and oil is sprayed around through the oil injection holes 72, so that the inner wall of the sealing sleeve is oiled. An annular groove 73 is opened on the outer periphery of the oil pipe 71, and a limiting disk 74 is sleeved on the outer periphery of the annular groove 73, wherein the diameter of the limiting disk 74 is larger than the outer diameter of the vertical shaft hole in the gas meter shell.

[0026] During use, when the gas meter housing moves to below the oiling mechanism 7, the guide rail 1 stops driving the movable plate 8. At this time, the telescopic member 6 is started to move the movable plate 5 downward, thereby moving the oiling mechanism 7 downward. At this time, the oil pipe 71 enters the vertical shaft hole, and sprays oil around through the oil spray hole 72, thereby oiling the inner wall of the sealing sleeve. At the same time, the limit plate 74 covers the vertical shaft hole to limit the sealing sleeve and the vertical shaft sleeve, and also effectively prevents dust from entering the vertical shaft hole and causing dust in the oil layer. When the oiling is completed, the telescopic member 6 is started to contract, thereby causing the oil pipe 71 to rise. During this process, the limit plate 74 is always covering the vertical shaft hole, thereby effectively preventing the sealing sleeve and the vertical shaft sleeve from being brought out by the oil pipe 71.

[0027] Furthermore, suction cups 75 are evenly arranged at the bottom of the limit plate 74, and a plurality of suction cups 75 are connected to connecting pipes 76, and the connecting pipes 76 are connected to an external suction pump. When the limit plate 74 covers the vertical shaft hole, the suction cups 75 will contact the platform formed on the top of the vertical shaft hole. By starting the suction pump, the suction cups 75 can be sucked above the vertical shaft hole, so that the limit plate 74 is fixed, which can further effectively prevent the sealing sleeve and the vertical shaft sleeve from being brought out by the oil pipe 71.

[0028] Furthermore, the length of the oil pipe 71 from the highest point of the annular groove 73 to the bottom of the oil pipe 71 is equal to the depth of the vertical shaft hole. In this way, when the oil pipe 71 enters the bottom of the vertical shaft hole, the limit plate 74 abuts against the highest point of the annular groove 73, so that the auxiliary suction cup 75 is sucked above the vertical shaft hole during the extrusion process. When the oil pipe 71 moves upward, the limit plate 74 will be slowly lifted up.

[0029] like Figure 1 and Figure 3 As shown;

[0030] A positioning mechanism 9 is installed between two adjacent guide rails 1. The positioning mechanism 9 includes a fixed plate 91. The fixed plate 91 is fixed between the two adjacent guide rails 1. A telescopic member 92 is installed at the bottom of the fixed plate 91. The telescopic member 92 can be a cylinder. The output end of the telescopic member 92 passes through the fixed plate 91 upward. A positioning plate 93 is fixed to the output end of the telescopic member 92. Positioning columns 931 are evenly arranged on the positioning plate 93. Positioning holes 81 are evenly opened on the movable plate 8. The positioning holes 81 match the positioning columns 931. When the movable plate 8 stops moving, the telescopic member 92 is started to insert the positioning columns 931 into the positioning holes 81, so that the movable plate 8 is positioned and fixed, and then the vertical shaft hole is positioned, which facilitates the oil pipe 71 to be inserted into the vertical shaft hole.

[0031] Furthermore, the fixing plate 91 is evenly provided with limiting posts 911 , and the limiting posts 911 all penetrate the positioning plate 93 . The limiting posts 911 can make the positioning plate 93 more stable when moving up and down.

[0032] Furthermore, a limit plate 11 is provided on the opposite side of the two adjacent guide rails 1. The limit plate 11 is L-shaped and matches the positioning plate 93. During the upward movement of the positioning plate 93, the positioning column 931 enters the positioning hole 81. At the same time, the positioning plate 93 moves upward to lift the movable plate 8 and makes the top of the movable plate 8 rest against the inner side of the limit plate 11, so that the movable plate 8 is fixed as a whole, thereby effectively preventing the gas meter housing from shaking when the sealing sleeve is oiled, which may cause the sealing sleeve or the vertical shaft sleeve to be brought out when the oil pipe 71 is collected.

[0033] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
