Description
Technical field
The utility model relates to a kind of electric liquid hammer, especially relates to a kind of mounting structure of electric hydraulic hammer unit head.
Background technology
Electricity liquid hammer obtains applying more and more widely with its energy-saving and environmental protection, easy to operate, laborsaving, the reliable feature of flexible movements.At present, the unit head of electricity liquid hammer is fixedly connected with connecting plate conventionally, casing becomes one by long bolt connection frame together with connecting plate, and the buffer spring being sleeved on long bolt is against between long bolt head and frame, because frame is steel-casting, the fillet of its junction is not of uniform size, pad between buffer spring and frame has inclination after cannot installing or install, cause contact area too small, the impact shock that long-time hammering causes makes the conquassation of buffer spring contact-making surface or the damage in frame, often need to carry out weld deposit repairing to frame, cause electric liquid hammer shutdown maintenance, reduce production efficiency, reduce output, increase maintenance workload and maintenance cost.In addition, because the length of long bolt is longer, although cover has lining on it, impact shock for a long time, screw rod and lining are prone to loosening, long bolt very easily ruptures, and porpoise born by lining, very easily causes lining to be cut off, equally also can increase the workload of maintenance, increase maintenance cost, and reduce production efficiency, reduce output.
Utility model content
The applicant, for above-mentioned problem, is studied improvement, and a kind of mounting structure of electric hydraulic hammer unit head is provided, and optimizes mounting structure, reduces electric liquid hammer fault power time, enhances productivity, and reduces maintenance workload, reduces maintenance cost, increases output.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of mounting structure of electric hydraulic hammer unit head, comprise the frame of arranged on left and right sides, the installation portion of the frame upper end of connecting plate and described arranged on left and right sides splices by notch, described connecting plate is fixedly connected with the first screw rod and nut that the frame of described arranged on left and right sides is set with lining by several, unit head is fixedly connected with described connecting plate, and the hammer stem lower end of described unit head connects tup; Casing is arranged on described connecting plate, the both sides, front and back of described connecting plate and casing are respectively equipped with flange, several second screw rods are through the flange of described connecting plate and casing, the lower end of described the second screw rod is fixed by lower nut, the top of described the second screw rod is set with buffer spring, the two ends of described buffer spring are respectively equipped with Upper gasket and lower gasket, and top nut is fixedly connected on the upper end of described second screw rod of described Upper gasket top; On the end face of the installation portion of described arranged on left and right sides frame, be respectively equipped with keyway, the arranged on left and right sides portion of described connecting plate bottom surface is respectively equipped with keyway, and two the first positioning keys are arranged on respectively in the installation portion of frame and the keyway of described connecting plate bottom surface of described arranged on left and right sides.
Further:
The arranged on left and right sides portion of described connecting plate end face is respectively equipped with keyway, and the arranged on left and right sides portion of described tank floor is respectively equipped with keyway, and two the second positioning keys are arranged on respectively in the keyway in described connecting plate end face and described tank floor.
Technique effect of the present utility model is:
The mounting structure of the disclosed a kind of electric hydraulic hammer unit head of the utility model; adopt between frame and connecting plate and be fixedly connected with; and the mounting structure that between connecting plate and casing, buffering is connected, and increase positioning key, strengthen overall rigidity; improve the performance of anti shock and vibration; reduce electric liquid hammer fault power time, enhance productivity, reduce maintenance workload; reduce maintenance cost, increase output.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises the frame 2 of arranged on left and right sides, connecting plate 3 splices by notch with the installation portion 201 of frame 2 upper ends of arranged on left and right sides, and unit head 5 is fixedly mounted on connecting plate 3, and hammer stem 501 lower ends of unit head 5 connect tup 1.On 8 the first screw rods 13, be set with lining 12, connecting plate 3 is fixedly connected with by 8 the first screw rods 13 and nut 14 with the frame 2 of arranged on left and right sides.Casing 4 is arranged on connecting plate 3, the both sides, front and back of connecting plate 3 and casing 4 are respectively equipped with flange, 8 the second screw rods 8 pass the flange of connecting plate 3 and casing 4, the lower end of the second screw rod 8 is fixing by lower nut 11, the top of the second screw rod 8 is set with buffer spring 9, the two ends of buffer spring 9 are respectively equipped with Upper gasket 7 and lower gasket 10, and top nut 6 is fixedly connected on the upper end of the second screw rod 8 of Upper gasket 7 tops.On the end face of the installation portion 201 of arranged on left and right sides frame 2, be respectively equipped with keyway, the arranged on left and right sides portion of connecting plate 3 bottom surfaces is respectively equipped with keyway, and two the first positioning keys 15 are arranged on respectively in the installation portion 201 of frame 2 and the keyway of connecting plate 3 bottom surfaces of arranged on left and right sides.Like this, the porpoise between installation portion 201 and the connecting plate 3 of the frame 2 being caused by hammering is born by the first positioning key 15, reduces lining 12 and is cut off probability, reduces electric liquid hammer fault power time, subtracts reduced-maintenance workload.The arranged on left and right sides portion of connecting plate 3 end faces is respectively equipped with keyway, the arranged on left and right sides portion of casing 4 bottom surfaces is respectively equipped with keyway, two the second positioning keys 16 are arranged on respectively in the keyway in connecting plate end face and tank floor, increase by two the second positioning keys 16, porpoise between casing 4 and the connecting plate 3 being caused by hammering is born by the second positioning key 16, alleviate the impact shock that the second screw rod 8 and buffer spring 9 bear, reduce the damage probability of the second screw rod 8 and buffer spring 9.
The utility model adopt between frame and connecting plate, be fixedly connected with and connecting plate and casing between the mounting structure that is connected of buffering, thereby obtain enough spatial enhance buffer springs, and increase positioning key, strengthen overall rigidity, the performance of raising anti shock and vibration.
