Abstract
The utility model discloses a piston rod which comprises a piston rod body (1) and a seal cover (2). The piston rod body (1) and the seal cover (2) are connected to form a cavity, the seal cover (2) comprises a water inlet (5), a water outlet (6) and a partition (7), the partition (7) is arranged in the cavity and partitions the cavity into a first chamber (3) and a second chamber (4) which are communicated with each other, and the water inlet (5), and the water outlet (6) are connected with the first chamber (3) and the second chamber (4) respectively. Cooling liquid is injected for cooling through the structure, and the cooling liquid is circulated to decrease the heating temperature in operation of the piston rod, so that the piston rod is less prone to swelling deformation under heating, precision of the piston rod is unaffected, and the service life of the piston rod can be prolonged.
Description
Technical field
The utility model relates to the auto parts machinery field, particularly a kind of piston rod.
Background technique
Piston rod in the existing auto parts machinery needs support piston to do ceaselessly in when work to move back and forth, used to make long afterwards the easy expanded by heating distortion of piston rod, thereby destroy the precision of piston rod, cause Efficiency Decreasing, reduced the working life of piston rod.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is the problem that will solve the easy expanded by heating distortion of piston rod.
(2) technological scheme
For addressing the above problem, piston rod of the present utility model comprises piston rod body and capping.Described piston rod body is connected with capping and forms cavity; Described capping includes water intake, water outlet and dividing plate, and described dividing plate is arranged in the cavity and cavity and is divided into the first chamber and the second chamber, described the first chamber and the circulation of the second chamber, and described water intake is connected respectively the first chamber and the second chamber with water outlet.Piston rod of the present utility model is realized cooling by this structure injection cooling liquid, and can make the cooling liquid circulation, thereby the heating temperature when reducing piston rod work makes piston rod be difficult for the expanded by heating distortion, the precision of piston rod can not destroyed, thereby carries the working life of piston rod.
In the above-mentioned piston rod, described piston rod also comprises filter, and described filter links to each other with water intake.
(3) beneficial effect
Piston rod of the present utility model is realized cooling by this structure injection cooling liquid, and can make the cooling liquid circulation, thereby the heating temperature when reducing piston rod work makes piston rod be difficult for the expanded by heating distortion, the precision of piston rod can not destroyed, thereby carries the working life of piston rod.
Description of drawings
Fig. 1 is the structural representation of piston rod of the present utility model;
1 is that piston rod body, 2 is that capping, 3 is that the first chamber, 4 is that the second chamber, 5 is that water intake, 6 is that water outlet, 7 is that dividing plate, 8 is filter among the figure.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, piston rod of the present utility model comprises piston rod body 1 and capping 2.Described piston rod body 1 is connected with capping 2 and forms cavity; Described capping 2 includes water intake 5, water outlet 6 and dividing plate 7, described dividing plate 7 is arranged in the cavity and cavity and is divided into the first chamber 3 and the second chamber 4, described the first chamber 3 and 4 circulations of the second chamber, described water intake 5 is connected respectively the first chamber 3 and the second chamber 4 with water outlet 6.Described piston rod also comprises filter 8, and described filter 8 links to each other with water intake 5.Parenteral solution can enter in the cavity by water outlet lowers the temperature, and flows out from water outlet 6 again.
Cooling liquid enters the workflow of piston rod: enter from water intake 5 first, after advancing filter 8 and filtering, flow in the first chamber 3, flow to the second chamber 4 from the first chamber 3 again, flow out from water outlet 6 at last.
Piston rod of the present utility model is realized cooling by this structure injection cooling liquid, and can make the cooling liquid circulation, thereby the heating temperature when reducing piston rod work makes piston rod be difficult for the expanded by heating distortion, the precision of piston rod can not destroyed, thereby carries the working life of piston rod.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
