[0031] Combine the following Figure 1-Figure 3 The technical solution provided by the utility model is described in more detail.

[0032] The connecting rod positioning and disassembling device provided by the utility model comprises a base plate 1, a positioning part 2, a positioning clamp 4 and a movable plate assembly 3, wherein: the positioning part 2 is fixed on the base plate 1, and is used to be inserted into the shaft sleeve of the connecting rod body 10; the positioning clamp 4 is fixed on the base plate 1, and is used to press the connecting rod body 10; the movable plate assembly 3 is slidably connected to the base plate 1, and the movable plate assembly 3 is used to be detachably connected to the connecting rod cover 11. After disassembling the connecting rod body 10 and the connecting rod cover 11, pulling the movable plate assembly 3 can separate the connecting rod cover 11 from the connecting rod body 10, so as to carry out cleaning work.

[0033] In the connecting rod positioning and disassembly device of this embodiment, the positioning part 2 is inserted into the sleeve of the connecting rod body 10, and the positioning clamp 4 presses the connecting rod body 10, thereby positioning the connecting rod body 10 on the base plate 1, and fixing the connecting rod cover 11 on the moving plate assembly 3. After removing the locking bolts between the connecting rod body 10 and the connecting rod cover 11, pull the moving plate assembly 3 to separate the connecting rod cover 11 from the connecting rod body 10, thereby cleaning the mounting surface of the connecting rod cover 11.

[0034] The “installation surface of the connecting rod cover 11 ” refers to a surface of the connecting rod cover 11 for connecting to the connecting rod body 10 .

[0035] The connecting rod positioning and disassembling device can position the connecting rod body 10 and realize the separation of the connecting rod body 10 and the connecting rod cover 11 without holding the connecting rod body 10, thereby reducing labor intensity, preventing the connecting rod cover 11 from falling, and improving work efficiency.

[0036] As an alternative embodiment, see Figure 1 As shown, the positioning portion 2 includes a positioning pin, which is vertically arranged.

[0037] The positioning pin can be inserted into the shaft sleeve of the connecting rod body 10 , thereby limiting the position of the connecting rod body 10 on the base plate 1 , making it easier for the positioning clamp 4 to press down the connecting rod body 10 .

[0038] As an alternative embodiment, see Figure 1-Figure 3 As shown, the movable plate assembly 3 of this embodiment includes a movable plate 31 and a pull rod 32, wherein: the movable plate 31 is slidably connected to the base plate 1 and is used to be detachably connected to the connecting rod cover 11, and the pull rod 32 is fixed to the upper surface of the movable plate 31 for the operator to hold.

[0039] The connecting rod body 10 and the connecting rod cover 11 are connected by bolts before disassembly. When the connecting rod body 10 is positioned on the bottom plate 1, a wrench is used to remove the bolts between the connecting rod body 10 and the connecting rod cover 11, and the pull rod 32 is held to pull the moving plate 31 to move, so that the connecting rod cover 11 fixed on the moving plate 31 is separated from the connecting rod body 10 by a certain distance, so as to clean the installation surface of the connecting rod cover 11.

[0040] Specifically, the connecting rod cover 11 can be fixed to the moving plate 31 by bolts, so that the connecting rod cover 11 and the moving plate 31 can move synchronously.

[0041] As an optional implementation, one of the movable plate 31 and the base plate 1 is provided with a guide rail 311 , and the other is fixed with a slider, which is slidably connected to the guide rail 311 .

[0042] See also Figure 3 As shown, in this embodiment, a guide rail 311 is provided on the movable plate 31 , and a slider is provided on the bottom plate 1 . The movable plate 31 and the bottom plate 1 are slidably connected to facilitate smooth movement of the movable plate 31 .

[0043] As an alternative embodiment, see Figure 1 As shown, the bottom plate 1 is further provided with limit posts 5 , which are located on both sides of the connecting rod body 10 and are used to limit the displacement of the connecting rod body 10 .

[0044] The limiting column 5 is used to abut against two sides of the connecting rod body 10 to further prevent the connecting rod body 10 from shifting, thereby improving the positioning effect.

[0045] As an alternative embodiment, see Figure 1 As shown, a pad 6 is also provided on the bottom plate 1 , and the positioning clamp 4 is fixed on the pad 6 , so that the positioning clamp 4 is pressed tightly against the upper surface of the connecting rod body 10 .

[0046] like Figure 1 As shown, the pad 6 positions the positioning clamp 4 at a certain height, so that the positioning clamp 4 is pressed against the upper surface of the connecting rod body 10 to prevent the connecting rod body 10 from moving.

[0047] As an alternative embodiment, see Figure 1 As shown, a pressing block 7 is also arranged on the bottom plate 1, and the pressing block 7 is fixed on two opposite sides of the bottom plate 1, and the movable plate assembly 3 is located between the pressing blocks 7 on both sides. The pressing blocks 7 arranged opposite to each other are used to prevent the movable plate assembly 3 from shifting left and right.

[0048] The pressing block 7 can make the movable plate 31 move between the pressing blocks 7 on both sides, preventing the movable plate 31 and the connecting rod cover 11 from being displaced left and right, and ensuring that the connecting rod body 10 and the connecting rod cover 11 can be directly docked and assembled after cleaning.

[0049] As an alternative embodiment, see Figure 1 As shown, a limit block 8 is also fixed on the bottom plate 1 , and the limit block 8 is arranged opposite to the positioning portion 2 . The limit block 8 is used to abut against the moving plate assembly 3 , thereby limiting the moving distance of the moving plate assembly 3 .

[0050] When the moving plate 31 abuts against the limiting block 8 , the connecting rod cover 11 and the connecting rod body 10 are separated by a sufficient distance, and a brush can be used to clean the mounting surface of the connecting rod cover 11 .

[0051] As an alternative embodiment, see Figure 1 and Figure 2 As shown, a movable block 9 is provided on the bottom plate 1 , and the movable block 9 is detachably connected to the bottom plate 1 . The upper surface of the movable block 9 and the upper surface of the movable plate 31 are located in the same plane, and the movable block 9 is used to support the connecting rod body 10 .

[0052] The movable block 9 can be connected to the bottom plate 1 by bolts. The movable block 9 supports the connecting rod body 10, and the movable plate 31 supports the connecting rod cover 11, so that the connecting rod body 10 and the connecting rod cover 11 are positioned on the same plane, which is convenient for separation and assembly of the two.

[0053] As an alternative embodiment, see Figure 1 and Figure 2 As shown, more than two positioning parts 2 and positioning clamps 4 are provided on the base plate 1 , and are used to position different connecting rod bodies 10 respectively.

[0054] The above structure can disassemble more than two groups of connecting rod bodies 10 and connecting rod covers 11 at the same time, thereby improving the cleaning efficiency.
