Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pump technology, and specifically relates to a hydraulic pump. Background Technology

[0002] Hydraulic pumps are a key component of hydraulic systems, primarily converting mechanical energy into hydraulic energy. They pressurize hydraulic oil through mechanical drive, propelling the fluid and driving other components in the hydraulic system (such as the primary hydraulic cylinder and hydraulic motor). Hydraulic pumps are commonly used in industrial applications requiring high-intensity power output, such as machinery manufacturing, construction engineering, mining, and aerospace. Hydraulic systems are also essential in construction projects, for example, for tasks like rebar cutting, pipe cutting, and straightening metal sheets. Therefore, it's common to transport pre-fabricated components to the construction site. However, the complexity and variability of construction projects mean that separating the fabricated components from the construction site cannot guarantee efficient operation. In other words, some component fabrication still needs to be performed on-site; for example, real-time secondary cutting of rebar to adapt to the building's specific requirements.

[0003] However, the construction site has a complex structure and occupies a large area, while the existing hydraulic system is bulky and difficult to move, making it inconvenient to transport on the construction site and unable to meet the needs of the construction site. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Real-time Example 1

[0032] Please see Figure 1-4As shown, a hydraulic pump includes a base 10, a hydraulic module 20, a drive mechanism 30, and a processing mechanism 40. The hydraulic module 20 is disposed at the bottom of the base 10, and the drive mechanism 30 is disposed on the base 10 and connected to the hydraulic module 20, for applying force to the hydraulic module 20. The processing mechanism 40 is located on the upper side of the base 10. When the drive mechanism 30 applies force to the hydraulic module 20, the hydraulic oil inside the hydraulic module 20 flows to the processing mechanism 40, causing the power output end of the processing mechanism 40 to extend, thereby achieving the purpose of processing parts.

[0033] Please see Figure 1-2 As shown, the base 10 includes a processing platform 11, which is used to place the parts to be processed. A support part 12 is provided on the lower side of the processing platform 11, which supports the processing platform 11. The support part 12 has an installation space inside, which is used to install the hydraulic module 20 and the drive mechanism 30. A fixing plate 15 is provided in the installation space, which is used to fix the hydraulic module 20 and the drive mechanism 30. A through hole 13 is provided at one end of the processing platform 11, which is vertically connected to facilitate the separation of materials from parts during processing. A connecting frame 14 is provided on the upper side of the processing platform 11, which is used to fix the processing mechanism 40, so that the processing mechanism 40 is located directly above the through hole 13.

[0034] Please see Figure 2 , Figure 4 As shown, the hydraulic module 20 includes an oil tank 22, which is connected to the lower side of the processing platform 11 and located inside the support part 12. The height of the oil tank 22 is less than the height of the support part 12 so that when the base 10 is placed on the ground, the oil tank 22 does not contact the ground, thus preventing damage to the oil tank 22. The oil tank 22 has a cavity 221 inside, which contains hydraulic oil. One end of the oil tank 22 is provided with a connecting pipe 23, one end of which is connected to the cavity 221 of the oil tank 22, and the other end is connected to the interior of the processing mechanism 40.

[0035] Please see Figure 2 As shown, the oil tank 22 is provided with two first hydraulic cylinders 21 along its length. Each first hydraulic cylinder 21 includes a cylinder barrel 212 and a piston rod 211. The interior of the cylinder barrel 212 is connected to the cavity 221 of the oil tank 22. The piston rod 211 can move along its axis. When the piston rod 211 moves towards the oil tank 22, it applies a force to the hydraulic oil inside the cavity 221, thereby driving the hydraulic oil to flow through the connecting pipe 23 to the machining mechanism 40, causing the power output end of the machining mechanism 40 to extend. In other embodiments, the number of first hydraulic cylinders 21 can be one, three, four, or more; the specific number of first hydraulic cylinders 21 is not limited.

[0036] Please see Figure 2 As shown, the drive mechanism 30 includes a movable plate 31 mounted on the end of the piston rod 211 of the two first hydraulic cylinders 21. A slider 312 is provided on the side of the movable plate 31 near the processing platform 11. A corresponding slide groove (not shown in the figure) is provided on the processing platform 11. The slide groove is parallel to the axis of the piston rod 211. The slider 312 is slidably mounted in the slide groove. The slider 312 and the slide groove are used to increase the stability of the movable plate 31 when it moves. A threaded hole 311 is provided on the movable plate 31.

[0037] Please see Figure 2 , Figure 3 As shown, the drive mechanism 30 also includes a motor 33 mounted on the fixed plate 15. The output shaft of the motor 33 is connected to a threaded rod 32. The other end of the threaded rod 32 is rotatably connected to the support part 12, and the threaded rod 32 is parallel to the axis of the first hydraulic cylinder 21. The threaded rod 32 passes through a threaded hole 311. When the motor 33 drives the threaded rod 32 to rotate, the rotating threaded rod 32 drives the moving plate 31 to move along the axis of the threaded rod 32, thereby further driving the piston rod 211 to move. A control switch 34 is provided on the upper side of the processing platform 11. The control switch 34 is electrically connected to the motor 33 and is used to control the start and stop of the motor 33.

[0038] Please see Figure 1 As shown, the processing mechanism 40 includes a second hydraulic cylinder. The housing of the second hydraulic cylinder is fixedly connected to the connecting frame 14. The oil chamber of the second hydraulic cylinder is connected to the connecting pipe 23. A processing tool is provided on the power output end of the second hydraulic cylinder. The processing tool is a cutting tool or a punching head. The processing tool is detachably connected to the power output end, including but not limited to threaded connection, snap-fit ​​connection and hinge connection, so as to facilitate the replacement of the corresponding tool according to the actual situation.

[0039] When processing the parts, the parts are placed on the upper side of the processing platform 11 and positioned directly below the processing mechanism 40. The motor 33 is started, and the motor 33 drives the moving plate 31 to move towards the oil tank 22 through the threaded rod 32. This causes the moving plate 31 to drive the piston rod 211 to move, applying force to the hydraulic oil inside the cavity 221. This forces the power output end of the processing mechanism 40 to extend and apply force to the parts, thus completing the processing of the parts.

[0040] For example, when it is necessary to cut the reinforcing bar, the reinforcing bar is placed on the upper side of the processing platform 11 and directly below the processing mechanism 40. The cutting tool on the processing mechanism 40 is a cutting blade. The motor 33 is started, and the power output end of the processing mechanism 40 extends, so that the cutting blade acts on the reinforcing bar to complete the cutting of the reinforcing bar. When it is necessary to stamp the steel plate, the steel plate is placed on the upper side of the processing platform 11 and directly below the processing mechanism 40. The cutting tool on the processing mechanism 40 is a stamping head. The motor 33 is started, and the power output end of the processing mechanism 40 extends, so that the stamping head acts on the steel plate to complete the stamping of the steel plate. The waste generated during the stamping process falls to the ground through the through hole 13. Example

[0041] Please see Figure 5 As shown, unlike Embodiment 1, one end of the threaded rod 32 is rotatably connected to the fixed plate 15, and the other end passes through the threaded hole 311 and the support part 12 in sequence and is connected to the turntable 36. The threaded rod 32 and the support part 12 are rotatably connected. By rotating the turntable 36, the threaded rod 32 is driven to rotate, which in turn drives the moving plate 31 to move.

[0042] Real-time Example 3

[0043] Please see Figure 6 , Figure 7 As shown, unlike Embodiment 1, the processing platform 11 is provided with a guide wheel 37, and the moving plate 31 is connected with a pull line 35. The end of the pull line 35 away from the moving plate 31 passes through the guide wheel 37, passes through the processing platform 11, and is located on the upper side of the processing platform 11. Pulling the pull line 35 drives the moving plate 31 to move.
