Abstract
The utility model discloses a hydraulic cylinder fork body which comprises a threaded shaft connected with a hydraulic cylinder and a flange arranged at one end of the threaded shaft. A transition shaft is arranged between the flange and the threaded shaft, and a first circular bead is used between the flange and the transition shaft for transition. A cone is arranged at the joint of the transition shaft and the threaded shaft, and a second circular bead is used between the cone and the threaded shaft for transition. According to the hydraulic cylinder fork body, the transition shaft is arranged between the flange and the threaded shaft, the method of circular bead transition is adopted between the transition shaft and the flange and between the transition shaft and the threaded shaft respectively, stress concentration is reduced, and the cracking phenomenon can be avoided.
Description
Technical field
The utility model belongs to hydraulic equipment, is specifically related to a kind of oil hydraulic cylinder fork body.
Background technique
Oil hydraulic cylinder with hydraulic pressure can change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).Its simple in structure, reliable operation.When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is used widely in the hydraulic system of various machineries.Existing oil hydraulic cylinder fork body comprises thread spindle and the one-body molded flange at this thread spindle one end that is connected with oil hydraulic cylinder, the circular cross-section of thread spindle is connected with the direct transition in the square-section of flange, the fork body of this structure can not make the active force diffusion that acts on the joint when hydraulic cylinder works, thereby make stress concentration distribution in the joint of thread spindle and flange, cause the joint fracture easily.
The model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model provides a kind of stress oil hydraulic cylinder fork concentrated and not easy-rupturing body that reduces.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of oil hydraulic cylinder fork body, it comprises the thread spindle that is connected with oil hydraulic cylinder and the flange that is arranged on thread spindle one end, be provided with transition axis between flange and the thread spindle, adopt first round-corner transition between flange and the transition axis, be provided with cone with the thread spindle joint on the transition axis, adopt second round-corner transition between cone and the thread spindle.
Wherein, the cone angle of cone is 152 °.
Wherein, offer on the flange for bearings mounted mounting hole, an end of mounting hole is provided with for the step against bearing, and the other end of mounting hole is provided with the collar groove for rigid bearing.
Wherein, the outer surface of flange is sphere.
(3) beneficial effect
Compared with prior art, the utility model is provided with transition axis between flange and thread spindle, and transition axis respectively and draw between orchid, the thread spindle and adopt round-corner transition reduces stress and concentrates, and avoids the phenomenon that occurs rupturing.
Description of drawings
Fig. 1 is the Facad structure schematic representation of the utility model oil hydraulic cylinder fork body.
Fig. 2 is the side structure schematic representation of the utility model oil hydraulic cylinder fork body.
Fig. 3 is the A-A sectional drawing of Fig. 1.
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 can not be used for limiting scope of the present utility model.
Structure such as Fig. 1, Fig. 2 and shown in Figure 3 of the utility model oil hydraulic cylinder fork body, this oil hydraulic cylinder fork body comprises the thread spindle 1 that is connected with oil hydraulic cylinder and the flange 2 that is arranged on thread spindle 1 one ends, be provided with transition axis 3 between flange 2 and the thread spindle 1, adopt 5 transition of first fillet between flange 2 and the transition axis 3, be provided with cone 31 with thread spindle 1 joint on the transition axis 3, adopt 6 transition of second fillet between cone 31 and the thread spindle 1.Wherein, the cone angle B of cone 31 is 152 °.
Wherein, offer on the flange 2 for bearings mounted mounting hole 21, one end of mounting hole 21 is provided with for the step 22 against bearing, the diameter of this step 22 is less than the diameter of mounting hole 21, the other end of mounting hole 21 is provided with the collar groove 23 for rigid bearing, this draws blue 2 the other end to be provided with the introduction hole 24 coaxial with mounting hole 21, and the diameter of this introduction hole 24 is greater than the diameter of mounting hole 21, can make things convenient for bearing to pack in the mounting hole like this.
Wherein, the outer surface of flange 2 is sphere, conflicts other parts when avoiding flange and other parts to install and causes phenomenon stuck or that scratch.
The utility model is provided with transition axis between flange and thread spindle, transition axis respectively and draw between orchid, the thread spindle and adopt round-corner transition reduces stress and concentrates, and avoids the phenomenon that occurs rupturing.
It below only is preferred implementation of the present utility model; should be pointed out 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.
