Description

Technical Field

[0001] The present application relates to the technical field of sleeve manufacturing, and in particular to a sleeve auxiliary lubrication device. Background Art

[0002] A socket is a tool typically used to tighten or loosen nuts or bolts. They can be attached to a wrench or spanner handle to provide better leverage and easier operation. A socket is a stepped column structure formed by cold stamping a hollow straight cylinder.

[0003] Before cold stamping the hollow straight cylinder, the center of the hollow straight cylinder needs to be inserted into the support column. After the cold stamping, a sleeve is formed. The inner wall of the sleeve will squeeze the support column, making it inconvenient for the sleeve to be separated from the support column. Therefore, before cold stamping, lubricating oil needs to be applied to the inner wall of the hollow straight cylinder to facilitate the separation of the sleeve from the support column after cold stamping. Conventionally, lubrication is performed through an inner hole brush. The specifications and sizes of conventional inner hole brushes are fixed and cannot be applied to the manufacture of sleeves of different specifications and sizes. Therefore, it is necessary to purchase inner hole brushes of different specifications and sizes to meet the processing requirements, but this also increases the production cost.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0032] An embodiment of the present application provides a sleeve auxiliary lubrication device, which can solve the problem of inconvenient oiling of sleeves of different sizes in the related art.

[0033] See also Figures 1 to 6 , a sleeve auxiliary lubrication device, comprising:

[0034] A center rod 1, one end of which is provided with a handle 2, and the handle 2 is provided with a plurality of annular grooves for the convenience of the staff to hold the handle 2;

[0035] A plurality of brush plates 3 are arranged around the central rod 1. The brush plates 3 are provided with bristles for applying oil. The bristles are dipped in oil and then brushed on the inner wall of the hollow straight cylinder to apply oil on the inner wall of the hollow straight cylinder.

[0036] Several connecting devices, each corresponding to a plurality of brush plates 3, the connecting device includes two connecting members 4, and the connecting member 4 includes:

[0037] -Fixed rod 41, fixed rod 41 is installed on the central rod 1;

[0038] - a telescopic rod 42 , the telescopic rod 42 is slidably connected to the fixed rod 41 , and one end of the telescopic rod 42 is connected to the brush plate 3 .

[0039] A cavity for accommodating the telescopic rod 42 is present in the fixed rod 41 , and at least a portion of the telescopic rod 42 is located in the cavity.

[0040] Two bosses 5 are provided on the central rod 1 . The two bosses 5 correspond to the two connecting members 4 of the same connecting device. The fixing rod 41 is connected to the bosses 5 .

[0041] The two connecting members 4 of the same connecting device are arranged on the same vertical line.

[0042] The fixing rod 41 is provided with a fixing hole 43, and the telescopic rod 42 is provided with a limiting hole 44;

[0043] The connecting device also includes a positioning rod 6;

[0044] The positioning rod 6 can pass through the fixing hole 43 , and the positioning rod 6 can be inserted into the limiting hole 44 .

[0045] The positioning rod 6 includes an outer rod 61, an inner rod 62, a plurality of hinges 63 and a limiting platform 64;

[0046] There is an inner cavity within the outer rod 61, and the inner rod 62 is slidably connected within the inner cavity;

[0047] One end of the hinge 63 is hinged to one end of the inner rod 62 , and a torsion spring 65 is provided between the hinge 63 and the inner rod 62 . The limit platform 64 is connected to the outer rod 61 , and the limit platform 64 is located at one end away from the hinge 63 .

[0048] The positioning rod 6 also includes a spring 65;

[0049] Both ends of the spring 65 are connected to the outer rod 61 and the inner rod 62 respectively.

[0050] Here's how this application works:

[0051] like Figure 1 As shown, the telescopic rod 42 is fixedly connected to the brush plate 3, and two telescopic rods 42 are connected to each brush plate 3 in the vertical direction. The center rod 1 and the boss 5 are an integrated structure, and the fixed rod 41 is fixedly connected to the boss 5. Compared with the fixed rod 41 being directly fixed on the center rod 1, the contact area between the boss 5 and the fixed rod 41 is larger, and the fixing rod 41 is more convenient to fix on the boss 5. At the same time, the boss 5 can connect more fixed rods 41 than the center rod 1. Providing the boss 5 on the center rod 1 can make the installation effect of the fixed rod 41 better.

[0052] In order to ensure the convenience of installation and disassembly and the efficiency of oiling, the number of brush plates 3 is three, ensuring that the brush plates 3 cover as much coating area as possible when the number of brush plates 3 is as small as possible. Accordingly, the number of connecting devices is three, that is, the number of each of the fixing rod 41, the telescopic rod 42, the fixing hole 43, and the limiting hole 44 is six, that is, the number of each of the outer rod 61, the inner rod 62, the limiting platform 64, and the spring 65 is three, and each inner rod 62 is connected to three hinges 63;

[0053] During installation, the two telescopic rods 42 on the same vertical line are respectively inserted into the two fixed rods 41 on the same vertical line, that is, the telescopic rods 42 are inserted into the cavities of the fixed rods 41, and the telescopic rods 42 slide in the cavities. The cavities limit the movable space of the telescopic rods 42, so that the telescopic rods 42 can only move in the direction close to or away from the center rod 1. At the same time, the cavity in the fixed rod 41 means that when the positioning rod 6 passes through the fixing hole 43 and the limiting hole 44, the positioning rod 6 fixes the telescopic rod 42 on the fixed rod 41. When the positioning rod 6 is sufficiently raised, as shown in FIG. Figure 1 As shown, a positioning rod 6 can directly fix the position of two telescopic rods 42 on the same vertical line, that is, a positioning rod 6 can fix the position of a brush plate 3. When disassembling, the above steps can be reversed;

[0054] During the installation and insertion of the positioning rod 6, the inner rod 62 is first pulled upward from the outer rod 61, and the three hinges 63 are retracted into the outer rod 61. At this time, the outer rod 61 and the inner rod 62 are simultaneously passed through the two fixing rods 41 until the limit platform 64 is close to one of the fixing rods 41. Then the inner rod 62 is released. Under the action of the spring 65, the inner rod 62 rebounds, and the three hinges 63 extend out of the outer rod 61. Under the action of the torsion spring 65, the three hinges 63 bend and fix the outer rod 61 and the inner rod 62 with the limit platform 64. To disassemble the positioning rod 6, first retract the three hinges 63 into the outer rod 61, and then pull out the inner rod 62 and the outer rod 61 at the same time to complete the disassembly.

[0055] In actual use, first adjust the positions of the three brush plates 3 according to the inner diameter of the hollow straight cylinder, that is, adjust the position of the telescopic rod 42 in the fixed rod 41, and then fix the position of the telescopic rod 42 by the positioning rod 6. After the adjustment is completed, the bristles of the brush plate 3 are dipped in oil, and the handle 2 is held to extend the brush plate 3 into the hollow straight cylinder. The device is rotated to apply the oil on the bristles to the inner wall of the hollow straight cylinder. This application designs a brush plate 3 with an adjustable distance from the center rod 1, so as to adjust the position of the brush plate 3 according to actual conditions to adapt to hollow straight cylinders with different inner diameters, thereby greatly improving the applicability of the device.
