Description

Technical Field

[0001] This utility model relates to the field of swashplate piston pump technology, and more specifically, to a swashplate for a swashplate piston pump. Background Technology

[0002] A piston pump is an important component of a hydraulic system. It relies on the reciprocating motion of a piston within a cylinder to change the volume of the sealed working chamber, thereby achieving oil suction and pressure. The swashplate is a crucial part of the piston pump. Traditional swashplate piston pumps mostly lack the ability to adjust the tilt angle, causing considerable inconvenience for users.

[0003] In the prior art, Chinese utility model publication CN217898089U discloses a swashplate for a swashplate piston pump. It features a threaded rod that is threadedly connected to a support column and rotatably connected to a first fixed block. Rotating the threaded rod adjusts the swashplate's tilt angle. Two threaded rods are located symmetrically on the upper and lower parts of the swashplate and are also threadedly connected to the other end of the support column. The other end of the threaded rod is rotatably connected to one side of the swashplate. This design solves the problem that most existing swashplate piston pumps lack the function of adjusting the tilt angle. The included ball bearings reduce internal wear in the mating hole, extending its service life. The spring and locking block ensure smooth connection, improving ease of connection and enhancing stability, preventing detachment. This avoids the inconvenience of installation and operation associated with existing swashplates used in piston pumps.

[0004] Although the above technical solution has a certain angle adjustment function, the angle adjustment requires the two sets of threaded rods to be rotated in opposite directions simultaneously. The operation steps are relatively complicated. Furthermore, if the reverse rotation cannot be performed simultaneously, the screw will jam, which will cause the swashplate to get stuck during angle adjustment. Therefore, the angle adjustment efficiency of the swashplate needs to be further improved. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a swashplate for a swashplate-type piston pump.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A swashplate for a swashplate piston pump includes a swashplate body. A first hinge seat and two sets of second hinge seats are mounted on one side of the swashplate body. A connecting member is rotatably connected to the first hinge seat. A locking component and an angle adjustment assembly are mounted on the connecting member. The locking component and the angle adjustment component are respectively rotatably mounted on the two sets of second hinge seats. The angle of the swashplate body is adjusted by the angle adjustment component. The locking component constrains the swashplate body after angle adjustment.

[0008] Furthermore, the locking assembly includes a frame and a movable column rotatably mounted on one of the second hinge seats. The other end of the movable column is disposed through the frame.

A tooth groove is provided on one side of the movable column for the teeth on the toothed block to be inserted.

[0009] Furthermore, the angle adjustment assembly includes an adjustment block and a screw. The adjustment block has a second screw hole for mounting the screw. One end of the screw is rotatably connected to a fixing block, which is rotatably mounted on another set of second hinge seats.

[0010] Furthermore, the first hinge seat is provided with an angle scale, and the fixing block is provided with an indicator arrow for indicating the tilt angle of the swashplate body.

[0011] Furthermore, the connector includes a connecting block, a connecting shaft, and two sets of mounting posts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: A swashplate for a swashplate-type piston pump, such as... Figures 1-6 As shown, the device includes a swashplate body 1. A first hinge 3 and two sets of second hinge 4 are installed on one side of the swashplate body 1. A connecting piece is rotatably connected to the first hinge 3. A locking component 8 and an angle adjustment component 9 are installed on the connecting piece. The locking component 8 and the angle adjustment component 9 are respectively rotatably installed on the two sets of second hinge 4. The swashplate body 1 can quickly adjust its angle through the angle adjustment component 9. The swashplate body 1 can quickly constrain itself after the angle adjustment through the locking component 8.

[0024] Furthermore, such as Figure 4As shown, the locking assembly 8 includes a frame 82 and a movable column 81 rotatably mounted on one of the second hinge seats 4. The other end of the movable column 81 passes through the frame 82. An inner groove 84 is formed on one side of the frame 82, and a toothed block 87 is slidably mounted within the inner groove 84. One side of the toothed block 87 has teeth. A first screw hole 86 is formed on the top of the frame 82, and a wing bolt 85, rotatably connected to the toothed block 87, is threaded into the first screw hole 86. A toothed groove 88 is formed on one side of the movable column 81 for the teeth on the toothed block 87 to engage. By providing the wing bolt 85, the position of the toothed block 87 in the inner groove 84 can be adjusted, facilitating the engagement of the teeth on the toothed block 87 into the toothed groove 88, thereby achieving mechanical locking of the movable column 81 and improving the stability of the swashplate body 1 after angle adjustment. Preferably, as... Figure 6 As shown, the wing bolt 85 and the toothed block 87 are rotatably connected by a rotating block 851 and a rotating groove 871. For example, a rotating block 851 is provided at the end of the wing bolt 85. The rotating block 851 is annular. A rotating groove 871 that matches the rotating block 851 is opened in the toothed block 87. When the wing bolt 85 rotates, it drives the rotating block 851 at its end to rotate together, so that the rotating block 851 rotates in the rotating groove 871, thereby causing the wing bolt 85 to rotate on the toothed block 87.

[0025] Furthermore, such as Figure 5 As shown, the angle adjustment assembly 9 includes an adjustment block 91 and a screw 93. The adjustment block 91 has a second screw hole 92 for mounting the screw 93, that is, the screw 93 is threaded to the second screw hole 92 of the adjustment block 91. One end of the screw 93 is rotatably connected to a fixing block 94. The fixing block 94 is rotatably mounted on another set of second hinge seats 4. The end of the screw 93 away from the fixing block 94 is provided with a knob 96 to facilitate the rotation of the screw 93. At the same time, the fixing block 94 is provided with a rotating hole for the screw 93 to be rotatably mounted, which improves the convenience of the screw 93 installation.

[0026] Furthermore, such as Figures 1-3 As shown, the connector includes a connecting block 5, a connecting shaft 6, and two sets of mounting posts 7. The connecting block 5 is rotatably mounted on one end of the connecting shaft 6, and the end of the connecting block 5 away from the connecting shaft 6 is rotatably mounted on the first hinge seat 3. The two sets of mounting posts 7 are respectively mounted on the two sides adjacent to the connecting block 5 and the connecting shaft 6. By symmetrically arranging the two sets of mounting posts 7, the movable post 81 and the screw 93 are arranged on the same plane, and the screw 93 and the movable post 81 are arranged parallel to each other, which improves the stability of the angle adjustment of the swashplate body 1.

[0027] The mounting post 7 has a mounting groove 71 at the end furthest from the connecting block 5 for mounting the frame 82 and the adjusting block 91. The frame 82 has a first rotating shaft 83 on both sides, and the adjusting block 91 has a second rotating shaft 95 on both sides. The mounting groove 71 has through holes 72 on both sides for rotating the first rotating shaft 83 and the second rotating shaft 95. By setting the first rotating shaft 83 and the second rotating shaft 95, the adjusting block 91 and the frame 82 adjust their angles during the angle adjustment process of the swashplate body 1, thus preventing the screw 93 from jamming and improving the smoothness of the angle adjustment of the swashplate body 1.

[0028] The first hinge seat 3 is provided with a first pin 10 rotatably connected to the connecting block 5, and the second hinge seat 4 is provided with a second pin 11 rotatably connected to the movable column 81 and the fixed block 94. Multiple sets of mating holes 2 are provided on the other side of the swashplate body 1. By utilizing the first pin 10 and the second pin 11, the installation efficiency of the locking assembly 8, the angle adjustment assembly 9, and the connecting block 5 is improved, sliding friction damage is reduced, the service life of the components is extended, and the overall structure is simple, reducing production costs.

[0029] The first hinge seat 3 is provided with an angle scale 12, and the fixing block 94 and the two sets of mounting posts 7 are provided with indicator arrows 13 on both sides to indicate the tilt angle of the swashplate body 1. During the angle adjustment process, the indicator arrows 13 indicate the angle scale 12 at different positions on the first hinge seat 3, making it easy to view the tilt angle of the swashplate body 1, thereby improving the accuracy of the tilt angle adjustment and realizing visual control.

[0030] When adjusting the angle of the swash plate body 1, first loosen the wing bolt 85 to move the tooth block 87 upward and disengage the teeth on the tooth block 87 from the tooth groove 88 on the movable column 81, thus releasing the mechanical lock on the movable column 81; then rotate the knob 96 at the end of the screw 93 to make the screw 93 rotate in the second screw hole 92. Since the adjusting block 91 is constrained and does not move, the fixing block 94 at the end of the screw 93 rotates with the second hinge seat 4 through the second pin 11, thereby causing the movable column 81 to rotate synchronously with the second hinge seat 4. The swash plate body 1 is adjusted in angle with the first pin 10 as the axis. The adjustment steps are simple and reduce the difficulty of operation.

[0031] After the angle adjustment is completed, tighten the wing bolt 85 to move the tooth block 87 downward and re-insert the teeth on the tooth block 87 into the tooth groove 88, thereby completing the mechanical locking of the movable column 81, further improving the stability of the swashplate body 1 after angle adjustment, and effectively preventing the swashplate body 1 from shifting at an angle.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
