DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] The utility model relates to a kind of industrial manipulator rotating seats of oil injection, including rotating seat 1, first interface 2 for connecting base and second interface 3 connected with large arm, as Figure 1 As shown.

[0021] Figures 1-3 The first embodiment of the utility model is shown: in the embodiment, the outer wall of second interface 3 is provided with injection hole 4 for oil injection, the upper side of injection hole 4 is fixedly connected with oil injection part 5, and oil injection part 5 includes oil injection pipe 51, which is connected to the inner wall of injection hole 4 through the outer wall.

[0022] As shown, Figure 3 The outer wall of oil injection pipe 51 is fixedly connected with connecting plate 52, and connecting plate 52 is provided with two groups, the positional relationship of the two groups of connecting plate 52 is symmetrically distributed about the center of oil injection pipe 51, the top of connecting plate 52 is provided with bolt 53, the outer wall of bolt 53 is threadedly connected with the inner wall of connecting plate 52, oil injection part 5 is fixed on the outer wall of second interface 3, the inner wall of first sealing cover 54 is provided with a threaded groove matched with the upper side of the outer wall of oil injection pipe 51, to prevent dust from entering the inside of oil injection pipe 51.

[0023] When in use, after unscrewing bolt 53, oil is injected into the inside of first interface 2 along the channel in the inside of oil injection pipe 51, and first sealing cover 54 is tightened after injection, to prevent the effect of sundries and dust from entering, lubricate the rotating part of the equipment.

[0024] Figures 4-5The second embodiment of the present invention is shown, which differs from the first embodiment in that: because the first embodiment may experience oil leakage and difficulty in opening the threaded connection after long-term use when injecting oil, in order to prevent oil leakage and facilitate opening the cap, an oil inlet pipe 6 is fixedly connected to the top of the oil injection pipe 51. The oil inlet pipe 6 is flared in appearance, which improves the convenience of oil injection and reduces the amount of oil leakage. A sealing component 7 is provided at the top of the oil inlet pipe 6.

[0025] Among them, such as Figure 5 As shown, the sealing component 7 includes a second sealing cover 71. An oil inlet pipe 6 is rotatably connected to one end of the outer wall of the second sealing cover 71. A supporting arc plate 72 is fixedly connected to the outer wall of the second sealing cover 71 away from the rotatable end. A fixing groove 73 is fixedly connected to the outer wall of the oil inlet pipe 6. A spring 74 is fixedly connected to the side of the supporting arc plate 72 away from the second sealing cover 71. A pull plate 75 is fixedly connected to one end of the spring 74. A pull ring 76 is fixedly connected to one side of the pull plate 75. A positioning post 77 is fixedly connected to the other side of the pull plate 75. The supporting arc plate 72 has a sliding groove that matches the positioning post 77. The fixing groove 73 has a slot that matches the positioning post 77 inside, which is used to fix the second sealing cover 71. When the pull plate 75 is pulled, the positioning post 77 slides in the groove of the supporting arc plate 72, so that the positioning post 77 moves away from the fixing groove 73, and the second sealing cover 71 can be opened quickly.

[0026] In practical use: the operator pulls the pull ring 76 outwards, causing the pull plate 75 to slide the positioning pin 77 in the groove of the support arc plate 72. The positioning pin 77 disengages from the slot of the fixing groove 73, causing the second sealing cover 71 to rotate around the oil inlet pipe 6, opening the oil injection channel and injecting oil into the interior. When sealing is required after oil injection, the pull ring 76 is pulled again, and the spring 74 retracts to pull the pull plate 75, causing the positioning pin 77 to insert into the groove of the fixing groove 73, thus completing the fixing. This facilitates opening the cover and prevents the threaded connection from being difficult to unscrew.
