Abstract
Description
Technical Field
[0001] This utility model relates to the field of plunger pump processing technology, specifically a hook device for processing copper bearing bushes of plunger pumps. Background Technology
[0002] Plunger pumps, as efficient and reliable conveying equipment, play a vital role in various industries. The copper bearing, as a core component, not only bears enormous axial pressure but also withstands the frictional forces generated by high-speed rotation. Therefore, the machining quality of the copper bearing directly affects the performance, efficiency, and lifespan of the plunger pump. However, existing methods for machining the hooks of copper bearings often rely on manual operation, which can easily lead to positional displacement of the bearing during processing, affecting machining accuracy. This necessitates multiple manual adjustments and fixations, which is time-consuming, labor-intensive, and results in low processing efficiency; it also makes it difficult to guarantee the quality stability of mass production. Therefore, this paper proposes a hook-bending device for machining plunger pump copper bearings to meet current practical needs. Utility Model Content

[0022] like Figure 1-7 As shown, this utility model addresses the problems of poor processing accuracy, low efficiency, and high cost caused by manual operation in the existing copper bearing processing, and provides the following technical solution: A hook device for processing plunger pump copper bearings, comprising a base plate 1; a base 2, which is fixedly disposed on the upper side of the base plate 1, with a supporting step 21 provided on the inner side wall of the base 2, and a pad 7 disposed opposite to the upper part of the base 2, with a first inclined surface 71 provided on the inner side of the pad 7; a hollow support column 4, disposed within the base 2, the space between the hollow support column 4 and the base 2 being used to place the plunger pump copper bearing 3, and a pressure block 5 slidingly disposed inside the hollow support column 4, the pressure block 5 being frustoconical in shape, with a drive mechanism at the bottom of the pressure block 5. The system includes a drive device 6; a fixed bushing 8, which is sleeved on the upper outer side of the base 2 and connected to the pad 7. Two limiting shafts 9 are inserted opposite each other on the fixed bushing 8 directly below the pad 7. The limiting shafts 9 are horizontally arranged and pass through the base 2 to separate the two plunger pump copper bearings 3; and a stamping block 10, which can be raised and lowered and is positioned directly above the pressure block 5. The stamping block 10 is provided with a second inclined surface 101 corresponding to the first inclined surface 71. Through the cooperation of the support step 21 on the base 2, the hollow support column 4, and the pressure block 5, the copper bearings are accurately positioned and pressed, effectively avoiding positional deviation during processing, improving processing accuracy, and facilitating quality control in mass production.
[0023] In this embodiment, as Figure 1 As shown, the bottom of the drive device 6 is provided with a mounting plate 11, and the mounting plate 11 and the base plate 1 are connected by pillars 12 located at the four corners. The structure is simple and easy to install.
[0024] In this embodiment, as Figure 5As shown, a third inclined surface 41 is provided on the inner side wall of the upper end of the hollow support column 4, and multiple vertical slots 42 are provided at intervals along the circumferential direction on the outer side wall of the hollow support column 4. The bottom of the slots 42 is transitioned by an arc. The slots 42 divide the hollow support column 4 into multiple support walls. When the pressure block 5 is pressed down, the support walls can spread out to support the plunger pump copper bearing 3.
[0025] In this embodiment, as Figure 4 As shown, the pad 7 has snap-fit protrusions 22 on both sides, which are fixedly connected to the base 2 and are used to limit the pad 7.
