Description

Technical Field

[0001] The invention relates to the technical field of striking head devices, in particular to a wear-resistant striking head. Background Art

[0002] The striking head refers to the striking head of an impact drill or some parts of tools with striking functions.

[0003] When the striking head is subjected to long-term striking operation, it will be worn out, thereby reducing its operating effect.

[0004] According to analysis, the wear of the striking head can be reduced when the striking head is kept vertical when in contact with the surface to be struck. However, during the striking operation, the surface to be struck is often an inclined surface with different inclinations. Generally, the striking head that is directly fixed and installed will suffer greater wear.

[0005] Furthermore, when the striking head strikes a very hard object, the striking head will be severely worn.

[0006] In view of the above problems, we designed a wear-resistant striking head, which is equipped with a driving part so that the direction of the striking head can be automatically adjusted so that the striking head remains vertical when in contact with the surface to be struck, and the maximum striking force of the striking head can be adjusted. The device is stable and has a long service life. Summary of the invention

[0050] The first box body 5 is a box body with an opening at the bottom.

The front outer wall of the second rotating column 14 is fixedly connected to the second mounting plate 29, and the bottom of the second mounting plate 29 is fixedly installed with a second box body 43. The striking rod 6 is installed in the second box body 43, so that the striking rod 6 can deflect forward and backward and left and right, so that the striking rod 6 remains vertical when in contact with the striking surface.

[0053] Two first connecting plates 22 are fixedly connected to the first rotating column 8 , and the front sides of the two first connecting plates 22 are commonly fixedly connected to a fixing plate 21 .

[0054] A second gear 15 is fixedly connected to the outer wall of the second rotating column 14 .

[0055] Two extension plates 16 are fixedly connected to the front side of the fixed plate 21, and a first threaded rod 17 is connected between the two extension plates 16 for limited rotation. The outer wall of the first threaded rod 17 is threadedly connected to a second rack 23.

[0057] Key References Figure 6A third mounting plate 31 is fixedly connected to the fixed plate 21, and the third mounting plate 31 and the extension plate 16 are jointly connected to a spline shaft 38 for limited rotation. A spline sleeve 39 is limitedly slidably connected to the outer wall of the spline shaft 38, and a seventh gear 40 is fixedly installed on the outer wall of the spline sleeve 39, and a bearing seat 41 is limitedly rotatably connected to the outer wall of the spline sleeve 39.

[0059] The outer wall of the spline shaft 38 is fixedly connected with the sixth gear 37, and the diameter of the sixth gear 37 is smaller than the diameter of the seventh gear 40, so that when the sixth gear 37 rotates one circle, the third gear 30 can rotate multiple circles, so that the sixth gear 37 that rotates one circle can drive the second rack 23 to move a greater distance, thereby driving the meshing action of the second gear 15 and the second rack 23.

[0061] The above structure can drive the striking rod 6 to deflect left and right when the third hydraulic cylinder 34 is activated, and drive the striking rod 6 to deflect front and back when the second hydraulic cylinder 12 is activated.

[0062] When the striking rod 6 is in operation, the bottom of the striking rod 6 is placed at the bottom outside the first box body 5. When the striking rod 6 is not in operation, the striking rod 6 can be deflected and leaned against the inner wall of the first box body 5, so that the end of the striking rod 6 is not exposed to the outside, thereby protecting the safety of the striking rod 6, so that the striking rod 6 will not be hit by the outside, resulting in excessive wear during the next operation, and the striking rod 6 deflected to one side can be easily cleaned or lubricated, thereby improving the wear resistance of the striking rod 6.

[0063] Embodiment 2: Based on Embodiment 1, a maximum striking force between the striking rod 6 and the striking surface can be adjusted, so that the maximum striking force can be adjusted for different contact surfaces, thereby reducing the wear of the striking rod 6 and increasing its wear resistance.

[0064] On the soft contact surface, a smaller striking force can be used, so that the striking rod 6 can have a longer life and wear resistance.

[0065] A harder contact surface can use a larger striking force, so that the striking operation can be better. However, when encountering a particularly hard object, if it is struck directly all the time, the striking rod 6 will be excessively worn.

[0066] This embodiment mainly includes a second box body 43 and a second threaded rod 19 .

The striking rod 6 is fixedly installed at the bottom of the mounting seat 49. The two limiting sliding sleeves 52 are close to each other so that the two second elastic members 56 press the isosceles wedge plate 59 so that the striking rod 6 sets the maximum striking force on the surface to be struck. When the striking rod 6 reaches the maximum striking force, the striking rod 6 moves upward to release the striking and reduce the wear of the striking rod 6.

[0070] Furthermore, a drilling machine can be installed at the mounting seat 49 without installing the striking rod 6, so that the device can perform punching and drilling operations.

[0071] Key References Figure 4A second threaded rod 19 is connected between the two extension plates 16 for limited rotation, and a first limit slide plate 26 is threadedly connected to the outer wall of the second threaded rod 19.

[0074] The device further comprises a controller, which is electrically connected to the second hydraulic cylinder 12 , the third hydraulic cylinder 34 , and the electric telescopic rod 42 .

[0075] The other structures of the second embodiment are the same as those of the first embodiment.

[0076] In the specific implementation, the right side of the striking rod 6 is first swung, and then the electric telescopic rod 42 is started to mesh the seventh gear 40 with the fifth gear 33 and the third gear 30 at the same time, and the third hydraulic cylinder 34 is started to keep the second rack 23 and the second gear 15 in meshing state, and then the third hydraulic cylinder 34 is started to deflect the second mounting plate 29 and the striking rod 6 to the left and right to a preset angle. Then the second hydraulic cylinder 12 is started to mesh the first rack 11 and the first gear 10, so that the second mounting plate 29 and the striking rod 6 are deflected to the preset angle forward and backward, so that the striking rod 6 is kept vertical when in contact with the striking surface, thereby reducing the wear of the striking rod 6.

[0077] At this time, the electric telescopic rod 42 is started so that the seventh gear 40 and the fourth gear 32 are engaged separately. At this time, the third hydraulic cylinder 34 is started so that the seventh gear 40, the fourth gear 32, and the second threaded rod 19 are rotated, so that the first limit slide plate 26 moves horizontally left and right. At this time, under the action of the first hinge rod 24, the slide bar 25 and the first pressure plate 28 move downward, so that the first pressure plate 28 presses the slide column 44, and the slide column 44 and the first pressure plate 28 are in a squeezed state. At this time, the slide column 44 drives the second limit slide plate 46 to move downward. The second elastic member 56 is compressed by the action of the second hinge rod 48. When the isosceles wedge plate 59 moves upward, it needs to overcome the pressing force of the second elastic member 56, and the pressing force at this time is the maximum striking force.

[0078] It should be noted that, under the limitation of the limiting baffle 55, the isosceles wedge plate 59 can maintain an inclined pressing state with the two single-sided inclined wedge plates 57, so that the device can maintain a stable control of the maximum striking force.

[0079] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
