Description
Technical field
The utility model relates to the gear pump field, particularly relates to a kind of pump cover of the gear pump for robot.
Background technique
Since 1978, gear pump just was applied to extruding on line of thermoplastic, and wherein most typical several utilizations field is plastics film-making, plastic material, casting film or blown film.Nowadays, gear pump has become requisite equipment in these actual production process, to such an extent as to the instrument manufacturers generally can sell gear pump and the packing of single screw extruder.General gear pump is all supporting a pump cover, and service time is of a specified duration, and the easy variation of sealing affects utilization efficiency.
The model utility content
The technical problem that the utility model mainly solves is to provide a kind of pump cover of the gear pump for robot, and simple in structure, sealing is strong, and water-proof performance is strong, long service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the pump cover that a kind of gear pump for robot is provided, comprise: pump cover main body, 8 mating grooves, 8 mounting holes, main shaft cylinder, cylinder connecting shaft hole and end cap cushion block, the surface of described pump cover main body has 8 mating grooves, described 8 mating groove inside have mounting hole, the center of described pump cover main body is equipped with the end cap cushion block, the edge of described end cap cushion block is provided with the main shaft cylinder, and the center of described main shaft cylinder has the cylinder connecting shaft hole.
In preferred embodiment of the utility model, described pump cover main body is made by high carbon steel.
In preferred embodiment of the utility model, the bottom of described pump cover main body is provided with seal ring.
In preferred embodiment of the utility model, described mounting hole is anti-water hole.
The beneficial effects of the utility model are: the pump cover of a kind of gear pump for robot of the utility model, and simple in structure, sealing is strong, and water-proof performance is strong, long service life.
Description of drawings
Fig. 1 is the structural representation of pump cover one preferred embodiment of a kind of gear pump for robot of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, mating groove, 2, the pump cover main body, 3, the end cap cushion block, 4, the main shaft cylinder, 5, the cylinder connecting shaft hole, 6, seal ring, 7, mounting hole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made more explicit defining.
See also Fig. 1, a kind of pump cover of the gear pump for robot, comprise: pump cover main body 2,8 mating grooves 1,8 mounting holes 7, main shaft cylinder 4, cylinder connecting shaft hole 5 and end cap cushion block 3, the surface of described pump cover main body 2 has 8 mating grooves 1, and described 8 mating groove 1 inside have mounting hole 7, and the center of described pump cover main body 2 is equipped with end cap cushion block 3, the edge of described end cap cushion block 3 is provided with main shaft cylinder 4, and the center of described main shaft cylinder 4 has cylinder connecting shaft hole 5.
In addition, described pump cover main body 2 is made by high carbon steel, and hardness is high, and easy-rupturing, stable not strong, long service life.
In addition, the bottom of described pump cover main body 2 is provided with seal ring 6, can increase the sealability of pump cover, prevents that in gear pump, liquid flows out.
In addition, described mounting hole 7 is anti-water hole, prevents from producing iron rust after long-time the use, causes pump cover to be not easy to dismounting.
Be different from prior art, the pump cover of a kind of gear pump for robot of the utility model, simple in structure, sealing is strong, and water-proof performance is strong, long service life.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
