Description

Technical Field

[0001] This utility model relates to the field of plunger pump processing technology, specifically a plunger pump clamping device that is easy to position. Background Technology

[0002] A piston pump is an important component of a hydraulic system. It relies on the reciprocating motion of a piston in a cylinder to change the volume of the sealed working chamber, thereby achieving oil suction and pressure. It is widely used in high-pressure, high-flow, and flow-adjustable applications.

[0003] Because plunger pumps come into contact with various liquids during daily use, a protective paint needs to be applied to the surface of the pump body during machining. This machining process requires a clamping device to hold the plunger pump casing in place before the painting work can proceed.

[0004] However, most existing clamping devices use external clamping, which, regardless of the shape of the clamp, will obstruct the outer surface of the plunger pump. When spraying protective paint, it is impossible to effectively paint the obscured parts, often requiring subsequent touch-up painting, which not only increases labor and time but also reduces work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a plunger pump clamping device that is easy to position. This solves the problem that most clamping devices use an external clamping method, which, regardless of the shape of the clamp, will obstruct the outer surface of the plunger pump. When spraying protective paint, it is impossible to effectively paint the obscured parts, and subsequent touch-up painting is often required.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a plunger pump clamping device for easy positioning includes a support unit, a clamping unit is provided on the support unit, and a rotating unit is provided on one side of the clamping unit;

[0007] The support unit includes a base plate and a vertical plate, with the vertical plate fixedly connected to the base plate;

[0008] The clamping unit includes a clamping seat, a fixing component, a pushing block, a square block, and a hydraulic rod. The clamping seat is rotatably connected to the vertical plate. The fixing component is movably disposed within the clamping seat. One end of the pushing block is connected to the fixing component. One end of the square block is fixedly connected to the other end of the pushing block. The hydraulic rod is rotatably connected to the other end of the square block.

[0009] Preferably, the clamping seat has a slot, and the slot has sliding grooves on both sides.

[0010] Preferably, the fixing component includes a pressing block, a slider, and a spring. The pressing block is slidably connected in the slot, the slider is fixedly connected to both sides of the pressing block, and one end of the spring is fixedly connected to the slider.

[0011] Preferably, the slider is slidably connected within the groove, and the other end of the spring is fixedly connected within the groove.

[0012] Preferably, the other end of the square block is provided with an arc-shaped groove, and the top end of the hydraulic rod is provided with an arc-shaped round head, which is rotatably connected in the arc-shaped groove.

[0013] Preferably, the rotating unit includes a first gear, a second gear, and a drive motor, wherein the second gear is meshed with the first gear, and the output end of the drive motor is connected to the second gear.

[0014] Preferably, the first gear is fixedly sleeved on the clamping seat.

[0015] Preferably, the other end of the hydraulic rod is connected to the hydraulic cylinder.

[0016] This utility model discloses a plunger pump clamping device that is easy to position, and its beneficial effects are as follows:

[0017] 1. This easy-to-position plunger pump clamping device, by fitting the plunger pump onto the clamping seat, activates the hydraulic cylinder to move the hydraulic rod, which in turn moves the square block within the clamping seat, thereby moving the pushing block. This causes the pushing block to abut against the pressing block, squeezing the pressing block outward, thus fixing the pressing block against the plunger pump. This achieves internal clamping of the plunger pump without obstructing its outer surface, allowing for painting of the plunger pump's outer surface and avoiding subsequent touch-up painting work, greatly improving production efficiency.

[0018] 2. This easy-to-position plunger pump clamping device, by setting a drive motor, can drive the second gear to rotate, which in turn drives the first gear to rotate, which in turn drives the clamping seat to rotate, so that the plunger pump can rotate on the clamping seat. This allows the plunger pump to be angled during the processing, achieving all-round processing and improving processing efficiency. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This utility model discloses a plunger pump clamping device that is easy to position.

[0028] According to the appendix Figure 1-5 As shown, it includes a support unit 1, a clamping unit 2 is provided on the support unit 1, and a rotating unit 3 is provided on one side of the clamping unit 2. The support unit 1 includes a base plate 11 and a vertical plate 12, and the vertical plate 12 is fixedly connected to the base plate 11.

[0029] Specifically disclosed, the clamping unit 2 includes a clamping seat 21, a fixing component 22, a pushing block 23, a square block 24, and a hydraulic rod 25. The clamping seat 21 is rotatably connected to the vertical plate 12. The fixing component 22 is movably disposed within the clamping seat 21. One end of the pushing block 23 is connected to the fixing component 22. One end of the square block 24 is fixedly connected to the other end of the pushing block 23. The hydraulic rod 25 is rotatably connected to the other end of the square block 24. By fitting the plunger pump onto the clamping seat 21 and activating the hydraulic cylinder to move the hydraulic rod 25, the square block 24 can be moved within the clamping seat 21, which in turn can move the pushing block 23, causing it to abut against the pressing block 221. This causes the pressing block 221 to move outward, thus fixing the pressing block 221 against the plunger pump and achieving internal clamping of the plunger pump.

[0030] Furthermore, the clamping base 21 is provided with a slot 211, and sliding grooves 212 are provided on both sides of the slot 211.

[0031] Specifically disclosed, the fixing component 22 includes a pressing block 221, a slider 222, and a spring 223. The pressing block 221 is slidably connected in the slot 211, the slider 222 is fixedly connected to both sides of the pressing block 221, and one end of the spring 223 is fixedly connected to the slider 222. When the pushing block 23 presses the pressing block 221 to move outward, the slider 222 can move in the groove 212, thereby causing the spring 223 to be compressed.

[0032] Furthermore, the slider 222 is slidably connected within the groove 212, and the other end of the spring 223 is fixedly connected within the groove 212.

[0033] It is particularly important to emphasize that the other end of the square block 24 is provided with an arc-shaped groove, and the top of the hydraulic rod 25 is set as an arc-shaped round head. The arc-shaped round head is rotatably connected in the arc-shaped groove, so that the hydraulic rod 25 will not rotate with the clamping seat 21 during the rotation process.

[0034] Specifically disclosed, the rotating unit 3 includes a first gear 31, a second gear 32, and a drive motor 33. The first gear 31 is fixedly sleeved on the clamping seat 21, and the second gear 32 is meshed with the first gear 31. The output end of the drive motor 33 is connected to the second gear 32. Through the drive motor 33, the second gear 32 can be driven to rotate, which in turn drives the first gear 31 to rotate, which in turn drives the clamping seat 21 to rotate. This allows the plunger pump to rotate on the clamping seat 21, enabling the plunger pump to adjust its angle during processing, achieving all-around processing and improving processing efficiency.

[0035] Furthermore, the other end of the hydraulic rod 25 is connected to a hydraulic cylinder, which can drive the hydraulic rod 25 to extend and retract.

[0036] Working principle: First, the plunger pump is fitted onto the clamping seat 21. The hydraulic cylinder is started to drive the hydraulic rod 25 to move, which in turn drives the square block 24 to move within the clamping seat 21, which in turn drives the push block 23 to move, so that the push block 23 abuts against the pressing block 221. The push block 23 squeezes the pressing block 221 to move outward, and the slider 222 moves within the slide groove 212 until the plunger pump is fixedly clamped on the clamping seat 21. At this time, the spring 223 is compressed.

[0037] Next, according to the processing angle of the plunger pump, the clamping seat 21 is rotated and adjusted. The drive motor 33 is started, which drives the second gear 32 to rotate, which in turn drives the first gear 31 to rotate, which in turn drives the clamping seat 21 to rotate, which in turn drives the plunger pump to rotate on the clamping seat 21, thus completing the angle adjustment.

[0038] After processing, when the plunger pump is removed from the clamping seat 21, the hydraulic cylinder drives the hydraulic rod 25 to move in the opposite direction, so that the hydraulic rod 25 does not abut against the square block 24, and the push block 23 is in a relaxed state. At this time, the spring 223 squeezes the slider 222 to reset, which in turn drives the pressing block 221 to reset. The pressing block 221 does not abut against the plunger pump, and the plunger pump is removed from the clamping seat 21.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
