Description

Technical Field

[0001] This utility model relates to the field of piston pump housing assembly technology, and in particular to a hydraulic piston pump housing assembly and flipping mechanism. Background Technology

[0002] Variable displacement hydraulic piston pumps are widely used in hydraulic systems of engineering machinery, metallurgical equipment, mining machinery, injection molding machines, and ships. They are particularly suitable for applications requiring hydrostatic drive and reversible motion, and can operate stably under high pressure. They offer high volumetric efficiency, smooth operation, good flow uniformity, and bidirectional variable displacement functionality, enabling switching of fluid flow direction. However, due to their complex structure and numerous parts, especially the housing, which requires the installation of other mating parts on both the upper and lower surfaces on a single workbench, their assembly presents challenges. Therefore, this invention addresses the housing flipping assembly requirement in variable displacement hydraulic piston pump assembly by proposing a hydraulic piston pump housing flipping mechanism, significantly improving assembly efficiency and product quality. Utility Model Content

[0003] The purpose of this invention is to provide a hydraulic plunger pump housing assembly and tilting mechanism to solve the problems mentioned above.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a hydraulic plunger pump housing assembly and tilting mechanism, comprising a lifting platform, a support base at the upper end of the lifting platform, bearing support seats symmetrically arranged on the top of the support base, and a main shaft rotatably mounted on the bearing support seats; one end of the main shaft is connected to a drive mechanism, and the other end is connected to a circular base plate; a large circular base plate is arranged at the end of the circular base plate away from the main shaft, and positioning side plates are symmetrically arranged on the large circular base plate; the tops of the positioning side plates are connected together by a positioning top plate, and the positioning top plate has several threaded holes for connecting the housing; a positioning cylinder for fixing the large circular base plate is provided on the side wall of the support base.

[0006] Furthermore, the support base includes a support base bottom plate located at the bottom, a support base side plate vertically arranged at the middle position of the upper end surface of the support base bottom plate, and a support base top plate arranged at the top of the support base side plate.

[0007] Furthermore, the positioning top plate has a large through hole for the assembly parts to pass through.

[0008] Furthermore, the large circular base plate is provided with a positioning hole that matches the output end of the positioning cylinder.

[0009] Furthermore, the lifting platform is a scissor lift platform, including a scissor mechanism and a drive device for driving the scissor mechanism to rise. The scissor mechanism is composed of multiple sets of intersecting beams connected by connecting rods, and the drive device is a hydraulic cylinder.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0011] This utility model relates to a hydraulic piston pump housing assembly and tilting mechanism. A lifting platform drives the overall tilting mechanism to move the housing up and down. The lifting platform lowers to facilitate placing the housing within the tilting mechanism frame. A positioning top plate is then fixed to the housing with screws. The lifting platform is then raised, and the circular base plate rotates, causing the housing to rotate as well. Once the housing is in position, a positioning cylinder locks the large circular base plate, fixing it in place. Subsequent assembly of the housing then begins. In summary, this utility model effectively solves the problem of needing to tilt the upper and lower surfaces during the assembly of a hydraulic variable displacement piston pump housing, improving assembly efficiency and product quality.

[0017] like Figure 1-3As shown, a hydraulic plunger pump housing assembly and tilting mechanism includes a lifting platform 1. A support base 2 is mounted on the upper end of the lifting platform 1. Bearing support seats 4 are symmetrically mounted on the top of the support base 2. A main shaft 3 is rotatably mounted on the bearing support seats 4. One end of the main shaft 3 is connected to a drive mechanism, and the other end is connected to a circular base plate 5. A large circular base plate 6 is mounted on the end of the circular base plate 5 away from the main shaft 3. In this embodiment, the drive mechanism is a servo motor 11. Positioning side plates 7 are symmetrically mounted on the large circular base plate 6. The tops of the positioning side plates 7 are connected together by a positioning top plate 8. The positioning top plate 8 has several threaded holes for connecting the housing 10. A positioning cylinder 9 for fixing the large circular base plate 6 is installed on the side wall of the support base 2. The large circular base plate 6 has positioning holes that cooperate with the output end of the positioning cylinder 9. The number of positioning holes is determined by the required rotation angle. When rotated to a fixed angle, the positioning holes and the telescopic end of the positioning cylinder 9 are on the same horizontal line. The telescopic end of the positioning cylinder 9 extends out and inserts into the positioning hole to quickly lock the large circular base plate 6, thereby ensuring that the housing 10 will not rotate with the large circular base plate 6 during the assembly process, improving assembly efficiency and quality.

[0018] The support base 2 includes a support base bottom plate 201 located at the bottom, a support base side plate 202 vertically installed at the middle position of the upper end surface of the support base bottom plate 201, and a support base top plate 203 installed on the top of the support base side plate 202.

[0019] The positioning top plate 8 has a large through hole 801 for assembly parts to pass through.

[0020] The lifting platform 1 is a scissor lift platform, including a scissor mechanism and a drive device for driving the scissor mechanism to rise. The scissor mechanism is composed of multiple sets of intersecting beams connected by connecting rods, and the drive device is a hydraulic cylinder.

[0021] The working process of this utility model is as follows:

[0022] First, the housing 10 is installed under the positioning top plate 8. During installation, the pre-drilled holes in the positioning top plate 8 match the housing 10. The positioning top plate 8 is then connected to the housing 10 using bolts. After tightening the bolts, the lifting platform 1 is started to rise. Once sufficient space for rotation is reached, the rising stops. Then, the servo motor 11 drives the main shaft 3 to rotate, causing the large circular base plate 6 to rotate 180°. Immediately afterward, the positioning cylinder 9 is activated. Once the telescopic end of the positioning cylinder 9 is inserted into the positioning hole of the large circular base plate 6, the rotation angle of the large circular base plate is fixed. Next, the relevant assembly parts are inserted through the large through hole 801 of the positioning top plate 8 and the assembly operation is completed. Finally, after assembly, the telescopic end of the positioning cylinder 9 retracts and disengages from the positioning hole. The servo motor 11 drives the main shaft 3 to rotate 180° in the opposite direction, the lifting platform 1 falls back, and the bolts of the positioning top plate 8 are loosened. This completes the assembly process of a portion of the housing 10's components for a single operation. The assembly operation of the next set of components can then proceed.

[0023] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
