[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] Please see Figures 1-4 This utility model provides a multi-station drilling device for hydraulic cylinders, including: a feeding mechanism 1, a fixing mechanism 2 disposed on the feeding mechanism 1, a support mechanism 3 adapted to the feeding mechanism 1, a lifting mechanism 4 disposed on the support mechanism 3, and a drilling mechanism 5 disposed on the lifting mechanism 4.

[0032] In some embodiments, the feeding mechanism 1 is a part of a multi-station drilling device used to transport hydraulic cylinders to a predetermined position for drilling. It includes: a first displacement component 11, a feeding box 12 connected to the first displacement component 11, a second displacement component 13 disposed in the feeding box 12, and a feeding plate 14 connected to the second displacement component 13. In some embodiments, the first displacement component 11 and the second displacement component 13 can be a mechanical transmission device capable of converting rotational motion into linear motion. In some embodiments, the first displacement component 11 and the second displacement component 13 can be a screw-slider structure, wherein the screw-slider structure can be driven by a motor to rotate the screw, and the rotational motion is converted into linear motion through a slider that engages with the screw thread.

[0033] Furthermore, by setting the first displacement component 11 and the second displacement component 13 perpendicular to each other, the first displacement component 11 drives the loading box 12, the second displacement component 13 and the loading plate 14 to move laterally, and the second displacement component 13 drives the loading plate 14 to move longitudinally, thereby realizing the lateral and longitudinal movement of the loading plate 14.

[0034] In some embodiments, the feeding box 12 is used to accommodate the second displacement component 13 on one hand, and on the other hand, the feeding box 12 is also slidably connected to the feeding plate 14. Specifically, the feeding box 12 is a box-shaped structure with an opening at the top, and first guide rails 121 are provided on both sides of its top. The bottom of the feeding plate 14 is provided with a first slider 141 that is adapted to the first guide rails 121. By slidably connecting the first slider 141 with the first guide rails 121, the first guide rails 121 are used to assist the feeding plate 14 in moving, thereby enhancing the smoothness of the feeding process of the feeding mechanism 1.

[0035] In some embodiments, a debris recovery box (not shown in the figure) may also be provided on the feed plate 14. The debris recovery box may be a structure with an opening at the top for recovering material debris generated during the drilling process (the lateral height should not interfere with the lateral drilling mechanism 5).

[0037] Furthermore, one end of both the transmission arm 24 and the clamping arm 25 is connected to the movable shaft 23, while the other ends are far apart. In some embodiments, the output end of the first telescopic cylinder 26 is connected to the transmission arm 24. Through the extension of the first telescopic cylinder 26, the clamping arm 25 is rotated via the transmission arm 24, thereby bringing the two sets of clamping arms 25 on the fixed base 21 closer to each other. Then, the end of the clamping arm 25 away from the movable shaft 23 is used to abut against the hydraulic cylinder to fix the hydraulic cylinder.

[0038] In some embodiments, the support mechanism 3 is a part of the multi-station drilling device used to support the lifting mechanism 4 and the drilling mechanism 5, and includes: a support base 31.

In some embodiments, the lifting mechanism 4 includes: a third displacement component 41, a lifting frame 42 connected to the third displacement component 41, a second slider 43 and a third slider 44 connected to the lifting frame 42. In some embodiments, the third displacement component 41 may also be a screw-slider structure, wherein the third displacement component 41 can be driven by a motor to rotate the screw, and the rotational motion is converted into linear motion by the slider that is threaded with the screw, thereby driving the lifting frame 42 connected to the slider to lift.

[0040] Furthermore, the lifting frame 42 is an n-shaped structure adapted to the support base 31. In some embodiments, the support base 31 is also provided with a second guide rail 32 and a third guide rail 33, wherein the second slider 43 is slidably connected to the second guide rail 32, and the third slider 44 is slidably connected to the third guide rail 33, thereby enhancing the smoothness of the lifting frame 42 during the lifting process of the third displacement component 41.

[0041] In some embodiments, the drilling mechanism 5 is a part of a multi-station drilling device used for drilling hydraulic cylinders, which includes: a drilling machine 51, a fourth slider 52 connected to the drilling machine 51, a fourth guide rail 53 adapted to the fourth slider 52, and a second telescopic cylinder 54 connected to the drilling machine 51.

Furthermore, the fourth guide rail 53 is fixed on the lifting frame 42, and the output end of the second telescopic cylinder 54 is connected to the drilling machine 51, thereby driving the drilling machine 51 to move along the setting direction of the fourth guide rail 53 to realize the drilling process of the hydraulic cylinder.
