Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment 1
Composition graphs 1, Fig. 2 and Fig. 3, a kind of of the present embodiment is convenient to housing structure in the hydraulic breaking hammer processed, and comprises middle cylinder body 1, is provided with plunger shaft 2, is provided with through oil machine in plunger shaft 2 in middle cylinder body 1, for lubrication, logical oil, transmits oil liquid pressure.This through oil machine comprises valve opening and leads to oil groove 3, middle part oil groove 4, fuel feed hole oil groove 5, neck oil groove 6 and encapsulation oil groove 7, in through oil machine, the right flank of each oil groove is all obliquely installed with vertical direction, and folded by the right flank of each oil groove and horizontal direction, obtuse angle is not less than 120 °.Due to the restriction of cutting-tool angle, when angle is less than 120 °, needs to change cutter, cause manufacturing procedure loaded down with trivial details.It should be noted that, the left side in the present embodiment is the left side of cylinder body 1 structure in Fig. 1, is provided with the side of neck extension, and right side is the right side of cylinder body 1 structure in Fig. 1.
The middle part oil groove 4 of the present embodiment is provided with 3, and in the middle part of this, oil groove 4 is for storing fluid, plays the effect to piston lubrication.Set valve opening leads to oil groove 3 and communicates, for changing piston movement direction with commutation valve opening; Fuel feed hole oil groove 5 and valve opening extension communicate, set middle part oil groove 4, valve opening lead to the right flank of oil groove 3 and fuel feed hole oil groove 5 and horizontal direction angle is 160 °, adopt same cutter, while axial feed, control the inclination right flank that radial feeds just can process middle part oil groove 4, valve opening leads to oil groove 3 and fuel feed hole oil groove 5, decrease the generation of wedge angle burr.When processing left surface, its inclination angle is controlled by cutting-tool angle, and namely left side corner angle is identical with cutting-tool angle, can realize the rounding off of end face and side.
Referring to Fig. 2 and Fig. 3, the neck oil groove 6 in the present embodiment is V-type groove, and the corner angle of this V-type groove is 120 °, adds neck oil groove 6 in man-hour side and can not interfere with the knife back, without the need to tool changing.Similarly, encapsulation oil groove 7 is dovetail groove, and the angle at encapsulation oil groove 7 right flank and top is 150 °, in the range of work of same cutter.
Because the utility model adopts the processing that one manufacturing procedure just can complete whole through oil machine, to produce burr few, plunger shaft finish is higher, without the need to polishing, the polishing in later stage, reduces the labour intensity of workman, improves working (machining) efficiency; As everyone knows, the performance impact of finish centering cylinder body is larger, find through experiment and actual use, the middle cylinder body of this structure is adopted not only not produce harmful effect, make the motion of piston more smooth on the contrary, the functional performance of quartering hammer is improved, and advances the development of hydraulic technique in quartering hammer.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
