Detailed Description

The above and further features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrated; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.

The first embodiment is as follows:

as shown in fig. 2 and 3, an oil block quick release structure of a KUKA robot speed reducer is provided. The plugging of the tight fit of the first and second oil filling ports of the KUKA robot is provided with an oil seal plug 1, the periphery of the oil seal plug is sleeved with a locking nut 2, and the locking nut 2 is in threaded connection with the periphery of the oil filling port. The oil seal plug 1 protrudes out of the cylinder of the upper end face of the locking nut 2 and is radially provided with a through hole, a limiting pin 3 is arranged in the through hole in a penetrating mode, the through hole extends out of two ends of the limiting pin 3, and the length of the limiting pin 3 is larger than the inner diameter of the locking nut 2. In the separation process of the locking nut 2 and the oil filling port, the locking nut 2 abuts against the limiting pin 3 in the thread strokes of the locking nut and the oil filling port.

The disassembly process adopting the oil plug quick-disassembly structure is as follows: the locking nut 2 is unscrewed by using a wrench, the locking nut moves upwards to abut against the limiting pin 3, and the axial force generated by the threads is applied to the limiting pin 3 to eject the oil seal plug 1 out of the oil injection port.

The oil plug quick-release structure has the advantages that:

the method can be applied to KUKA multi-series robots, and is convenient for disassembling a plug when the reducer is used for changing oil.

c, violent disassembly is not needed, and the plug is not damaged.

b, the damaged tool does not need to be knocked violently by the tool.

And c, eliminating the potential safety hazard of smashing injury in the operation process.

And e, improving the working efficiency by 500 percent in the disassembling process, and reducing the time from the original 10 minutes to the current 2 minutes.

Example two:

as shown in fig. 4, the difference between the second embodiment and the first embodiment is: the through hole at the upper end of the oil seal plug 1 is in clearance fit with the limiting pin 3. When installing oil blanket end cap 1 on the oiling mouth, can conveniently separate spacer pin 3 and oil blanket end cap 1, the suit of lock nut 2 is screwed up on oil blanket end cap 1, installs spacer pin 3 again, perhaps installs spacer pin 3 again when oil blanket end cap 1 needs to be dismantled.

Preferably, one end position close to the limit pin radially penetrates through a small hole 31, a pull ring 5 is fixed by the small hole 31, and the limit pin 3 can be conveniently separated from the oil seal plug 1 by pulling the pull ring 5. And the pull ring 5 can be sleeved on the finger after the limit pin 3 is dismounted, so that the loss of the limit pin 3 when the oil seal plug 1 is dismounted is avoided.

Preferably, the rear part of the threaded section of the oil filling opening is provided with a regular hexagon clamping ring 4. Because the hose is usually connected to the lower extreme of oiling mouth, when installing and dismantling lock nut 2, can use a spanner fixed snap ring 4, use another spanner rotatory lock nut 2, avoid haring oiling mouth and hose.

The foregoing is merely a preferred embodiment of the invention, which is intended to be illustrative, not limiting. The utility model discloses in all can change to some extent structure and connected mode etc. of each part all be in the utility model discloses equal transform and the improvement of going on technical scheme's the basis all should not get rid of the utility model discloses an outside the protection scope.
