Abstract
The utility model relates to a rotating constant-impacting mechanism which can be used for various power tools, wherein the power tools can produce constant-impacting force in radial direction. The rotating constant-impacting mechanism comprises a shell, an incus jacket, torsion bar springs, an output shaft, a stamping hammer, and an input shaft. Concave grooves are formed in the middle portion of the external wall of the input shaft and the torsion bar springs are installed in the concave grooves. The torsion bar springs are fixed on the two ends of the concave grooves through a first pin nail and a second pin nail. The middle portion of the spring can be formed into an external spline, wherein the external spline is sleeved with the stamping hammer and the stamping hammer is fixed through a third pin nail. The outer surface of the stamping hammer is a cam structure. An involute curve surface is installed on the external surface of the incus jacket and connected with the external spline through an internal spline, wherein the external spline is out of the output shaft. Power source drives the input shaft to rotate. The input shaft drives the torsion bar spring to rotate in a circular mode. Torsion bar springs drive the stamping hammer to twist and strike the incus jacket so that the incus jacket can be twisted to elastic deformation to form a ratchet mechanism. Therefore, rotating constant-impacting can be achieved and impacting energy can be transferred to the output shaft through the incus jacket. The output shaft can transfer the energy to downhole tools.
Description
Technical field
The utility model relates to a kind of rotation bump mechanism, can be used for radially producing the various power tools of bump, and such as electronic, pneumatic torsion dismantling device, boring bar tool, oil and gas well drilling well dynamic instrument etc. belong to the rotary impact tool field.
Background technology
The existing mechanism that produces radial impact and percussion action mainly adopts electronic, pneumatic torque spanner, announce a kind of rotary impact tool such as 200820033946.8, basic principle is the rotation of actuating unit driving shaft, axle rotarily drives jump bit bump output shaft, utilizing ball, ball groove and offsetting spring structure promotion jump bit to move axially makes jump bit separate with output shaft, jump bit homing under action of reset spring then produces next time and impacts.
This class formation has following shortcoming: the one, because back-moving spring easily lost efficacy when high-frequency percussion, service life is short, causes frequency of impact low, and it is discontinuous to show as impact; The 2nd, it is little to produce torsion, and parts require very high to material; The 3rd, application is narrower, substantially only is used in fastened by screw and dismounting.
The utility model content
The purpose of this utility model be for overcome the existing radial impact mechanism life-span short, frequency of impact is low, produce the defectives such as torsion is little, and a kind of rotation bump mechanism is provided, and can be used for radially producing the various power tools of bump.
For addressing the above problem, the technical solution adopted in the utility model is:
A kind of rotation bump mechanism, comprise shell, incus cover, torsion-bar spring, output shaft, block stamp, power shaft, have axial notch on the outer wall of power shaft middle part, torsion-bar spring is installed in the groove, torsion-bar spring is fixed on the two ends of the groove of power shaft by the first pin and the second pin; Torsion-bar spring middle part cover has block stamp, and fixes by the 3rd pin; The incus cover is connected with the output shaft external splines by internal spline.
The axial notch that has on the outer wall of power shaft middle part can be uniform three or four, forms ratchet structure by torsion-bar spring, block stamp and the incus cover installed in the groove.
External splines is arranged in the torsion-bar spring middle part, and the block stamp outer surface is cam structure, and incus cover outer surface is provided with involute surface.
Power source drives power shaft and rotates, power shaft drives the torsion-bar spring circular-rotation, torsion-bar spring drives the block stamp twisting, make block stamp bump incus cover, impel its elasticity of torsion distortion, form ratchet mechanism, thereby realize rotation bump, and by the incus cover Impact energy being passed to output shaft, output shaft passes to downhole tool with energy.But the utility model bump, frequency of impact is high.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is A-A directional profile schematic diagram among Fig. 1.
The specific embodiment
The utility model embodiment such as Fig. 1～shown in Figure 2, comprise shell 7, incus cover 3, torsion-bar spring 2, output shaft 4, block stamp 5, power shaft 9, have axial notch 12 on the power shaft 9 middle part outer walls, torsion-bar spring 2 is installed in the groove 12, and torsion-bar spring 2 is fixed on the two ends of the groove 12 of power shaft 9 by the first pin 1 and the second pin 8; External splines is arranged in torsion-bar spring 2 middle parts, and cover has block stamp 5 on its external splines, and fixing by the 3rd pin 6; Block stamp 5 outer surfaces are cam structure; Incus overlaps 3 outer surfaces and is provided with involute surface, is connected with output shaft 4 external splines by internal spline.
The axial notch 12 that has on the described power shaft 9 middle part outer walls can be uniform three or four, forms ratchet structure by torsion-bar spring 2, the block stamp 5 installed in the groove 12 with incus cover 3.
During work, power source band driven input shaft 9 is with respect to shell 7 circular-rotations, driving torsion-bar spring 2 rotates, torsion-bar spring 2 drives block stamp 5 twistings under the spline effect, impel block stamp 5 outer surface striking faces 11 bump incus to overlap 3 outer surfaces and hold the face of hitting 10, the reaction force acts of bump moment generation is in torsion-bar spring 2, impel its elasticity of torsion distortion, under elasticity of torsion distortion and block stamp 5 circular-rotation effects, block stamp 5 outer surface striking faces 11 leave incus and overlap 3 outer surfaces and hold the face of hitting 10, after block stamp 5 and incus overlap 3 striking faces and leave, reaction force disappears, torsion-bar spring 2 returns impel block stamp 5 to overlap 3 involute returns along incus, clash into next time, form ratchet mechanism, thereby realize rotation bump, and by incus cover 3 Impact energy is passed to output shaft 4, output shaft 4 passes to energy other instrument again.
