Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic fixtures for piston pumps, specifically relating to a tooling for assembling and flipping piston pumps. Background Technology

[0002] A piston pump relies on the reciprocating motion of a piston within the cylinder bore to create changes in the sealed volume, thereby achieving oil suction and discharge. Axial piston pumps offer advantages such as compact structure, high operating pressure, and ease of variable displacement control. These pumps are widely used in agricultural and forestry machinery, lifting and transportation equipment, construction machinery, marine deck machinery, metallurgical equipment, artillery, and space technology.

[0003] Current plunger pumps are mainly used in high-pressure applications. They have a complex structure and are relatively heavy. Assembly or maintenance requires repeated turning over, which presents the following drawbacks in the current assembly process:

[0004] On the one hand, the clamping structure needs to be manually operated to fix the plunger pump, resulting in low fixing efficiency. On the other hand, it also requires manual rotation or circumferential angle adjustment, which is difficult and labor-intensive.

[0005] Secondly, the tooling cannot be folded after use, which results in it occupying a lot of external space when not in use. To address this, we have proposed a tooling for assembling a plunger pump that can be flipped. Utility Model Content

[0006] The purpose of this invention is to provide a tooling for assembling and reversing a plunger pump, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a plunger pump tilting fixture, including a support box base, a motor a fixedly connected to the inner wall of the support box base, the output shaft of the motor a passing through the support box base and fixedly connected to a rotating plate, an operating table hinged to the bottom end of the rotating plate, an assembly table with a circular cross-section rotatably connected to the through circular opening on the operating table via a slewing bearing, a rotary transmission structure connecting the assembly table and the operating table, and a clamping and fixing structure installed on the assembly table, the rotary transmission structure being used to rotate and adjust the angle of the assembly table, and the clamping and fixing structure being used to clamp and fix the plunger pump to the top of the assembly table;

[0008] The folding and fixing structure is installed on the rotating plate and connected to the operating table. When the tooling is not in use, the operating table can be folded and fixed close to the rotating plate.

[0009] In a preferred embodiment, the rotary transmission structure includes a gear ring fixed to the outside of the assembly table, a gear meshing with the outside of the gear ring, a motor b fixed to the bottom right edge of the operating table, the output shaft of the motor b passing through the operating table and fixedly connected to the mounting shaft hole of the gear.

[0010] In a preferred embodiment, the clamping and fixing structure includes a motor c fixedly connected to the center of the bottom end of the assembly table, and the output shaft of the motor c extends into a circular cavity provided on the inner side of the assembly table and is fixedly connected to a turntable.

[0011] In a preferred embodiment, the turntable has multiple inclined slots arranged in a circular array. The inclined slots are movably sleeved on the outside of the transmission column. The top of the transmission column is fixedly connected to a slider with an I-shaped vertical cross section. The slider is slidably connected to a groove provided at the top of the assembly table. The top of the slider is fixedly connected to a clamping plate.

[0012] In a preferred embodiment, the folding and fixing structure includes sliding grooves on both sides of the rotating plate, and sliding seats with convex cross-sections are slidably connected in the sliding grooves. Push-pull rods are rotatably connected to the outer side of the sliding seats, and the bottom ends of the push-pull rods are hinged to the outer side of the operating table.

[0013] In a preferred embodiment, each sliding seat is movably fitted with a hand-tightening screw, one end of which is threaded into a lower screw hole provided in the inner wall of the sliding groove, and an upper screw hole is provided above the lower screw hole in the inner wall of the sliding groove.

[0014] Compared with the prior art, the plunger pump tilting fixture provided by this utility model has at least the following beneficial effects:

[0015] Through the set rotary transmission structure, the starting motor b, and the action of multiple components, can adjust the circumferential angle of the plunger pump fixed on the assembly table by the clamping and fixing structure. In addition, with the action of motor a, the pitch angle of the plunger pump can be adjusted at the same time to meet the usage requirements of different angles during assembly or maintenance.

[0016] (2) By setting up a folding and fixing structure, when the flip tooling is not in use, the two hand screws can be loosened and the worktable can be flipped up and brought close to the rotating plate. At this time, with the help of the two push-pull rods, the two sliders will move up and the hand screws will be manually locked to the position of the upper screw hole, thereby achieving the purpose of easy folding and reducing the external space occupied by the tooling when it is not in use.

[0017] (3) The clamping and fixing structure can be used to quickly clamp and fix the plunger pump without manual operation of the clamping structure. It is convenient to use and has high clamping and fixing efficiency. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments.

[0026] 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 some, but 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.

[0027] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by a person skilled in the art to which this disclosure pertains. The words “comprising” or “including” and similar terms used in this disclosure mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects. The words “connected” or “linked” and similar terms are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. “Up,” “down,” “left,” “right,” etc., are used only to indicate relative positional relationships.

[0028] On the one hand, the clamping structure needs to be manually operated to fix the plunger pump, resulting in low fixing efficiency. On the other hand, it also requires manual rotation or circumferential angle adjustment, which is difficult and labor-intensive.

[0029] Secondly, the tooling cannot be folded after use, resulting in it occupying a lot of external space when not in use.

[0030] For this purpose, please refer to Figure 1-6 This utility model provides a tooling for assembling a plunger pump and flipping it over, including: a support box 1, a motor a2 fixedly connected to the inner wall of the support box 1, the output shaft of the motor a2 passing through the support box 1 and fixedly connected to a rotating plate 21, an operating table 22 hinged to the bottom end of the rotating plate 21, an assembly table 3 with a circular cross-section rotatably connected to the through circular opening on the operating table 22 through a slewing bearing, a rotary transmission structure 4 connecting the assembly table 3 and the operating table 22, and a clamping and fixing structure 5 installed on the assembly table 3. The rotary transmission structure 4 is used to rotate and adjust the angle of the assembly table 3, and the clamping and fixing structure 5 is used to clamp and fix the plunger pump to the top of the assembly table 3.

[0031] The folding and fixing structure 6 is installed on the rotating plate 21 and connected to the operating table 22. When the tooling is not in use, the folding and fixing structure 6 can fold and fix the operating table 22 against the rotating plate 21.

[0032] Further as Figure 1-6 As shown, it is worth noting that in order to adjust the circumferential angle of the plunger pump on the assembly table 3, a rotary transmission structure 4 is provided, including a gear ring 41 fixed to the outside of the assembly table 3. A gear 42 is meshed with the outside of the gear ring 41. A motor b43 is fixed to the bottom right edge of the operating table 22. The output shaft of the motor b43 passes through the operating table 22 and is fixed to the mounting shaft hole of the gear 42.

[0033] Among them, the motor b43 drives the gear 42 to rotate and can transmit power to the gear ring 41, thereby enabling the assembly table 3 to rotate on the operating table 22 via the slewing bearing to adjust the circumferential angle.

[0034] Further as Figure 1-6 As shown, it is worth noting that in order to facilitate the quick clamping and fixing of the plunger pump on the assembly table 3, a clamping and fixing structure 5 is provided, including a motor c51 fixed at the center of the bottom end of the assembly table 3. The output shaft of the motor c51 extends into a circular cavity provided on the inner side of the assembly table 3 and is fixed to a turntable 52. The turntable 52 has multiple inclined slots 53 arranged in a circular array. The inclined slots 53 are movably sleeved on the outside of the transmission column 54. The top of the transmission column 54 is fixed to a slider 55 with a vertical cross section of I-shaped structure. The sliders 55 are slidably connected in the sliding groove provided at the top of the assembly table 3. The top of the sliders 55 is fixed to a clamping plate 56.

[0035] The width of the inclined groove 53 is equal to the diameter of the transmission column 54, and multiple sliding grooves are connected to the circular cavity. The bottom end of the slider 55 is movably attached to the top surface of the turntable 52.

[0036] Further as Figure 1-6 As shown, it is worth noting that in order to facilitate the fixing of the operating table 22 when it is folded or unfolded in parallel, a folding fixing structure 6 is provided, which includes sliding grooves on both sides of the rotating plate 21. Sliding seats 61 with convex cross-sections are slidably connected in the sliding grooves. Push-pull rods 63 are rotatably connected to the outside of the sliding seats 61. The bottom ends of the push-pull rods 63 are hinged to the outer side of the operating table 22. Hand screws 62 are movably inserted on the sliding seats 61. One end of the hand screws 62 is threaded into the lower screw hole provided in the inner wall of the sliding groove. Above the lower screw hole, there is also an upper screw hole 64 provided in the inner wall of the sliding groove.

[0037] The lower screw hole is not shown in the diagram. Figure 6 In the middle, when you hand-tighten one end of screw 62, it is locked in the lower screw hole.

[0038] In summary: When using this plunger pump tilting fixture, firstly, the plunger pump is placed at the top center of the assembly table 3. By starting the motor c51, the turntable 52 rotates at a certain angle. With the help of multiple inclined slots 53, multiple sliders 55 drive the clamping plates 56 to move closer to the periphery of the plunger pump, thereby achieving quick clamping and fixing of the plunger pump. Secondly, by starting the motor a2, the tilt angle of the operating table 22 connected to the rotating plate 21 via the folding fixing structure 6 can be adjusted. At the same time, by starting the motor b43, the gear 42 is driven to rotate, which can transmit power to the gear ring 41. This allows the assembly table 3 to rotate on the operating table 22 via the slewing bearing to adjust the circumferential angle, thereby meeting different angle requirements when assembling or repairing the plunger pump.

[0039] Motors a2, b43, and c51 can be purchased commercially. Motors a2, b43, and c51 are equipped with power supplies. This is a mature technology in the field and has been fully disclosed, so it will not be repeated in the specification.
