Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plunger pump installation, in particular to an assembling mechanism for the intermediate body of a series plunger pump. Background Technique
[0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, and convenient flow regulation.
[0003] However, the workpieces of the series plunger pump are very heavy and large, making it difficult to assemble in series, resulting in difficult manual installation and low production efficiency. Content of the Utility Model

To achieve the above objectives, the utility model is realized through the following technical solutions: An assembling mechanism for the intermediate body of a series plunger pump, including a base, on the top of the base are assembled a front pump clamp, an intermediate connection clamp, and a rear pump clamp, and on the sides of the front pump clamp and the rear pump clamp are assembled handwheels for adjusting the position.
[0005] Preferably, the front pump clamp and the rear pump clamp are symmetrically distributed with respect to the intermediate connection clamp.
[0006] Preferably, a deceleration assembly is provided on the top of the base. The deceleration assembly includes a rotating disk, on the outside of the rotating disk is fixedly connected a hydraulic chamber, inside the hydraulic chamber is slidably connected a power block, on the side of the power block is fixedly connected a spring, on the side of the hydraulic chamber is slidably connected an arc-shaped rod, the outside of the arc-shaped rod is coated with a rubber friction pad, and on the side of the base is fixedly connected a friction plate.
[0007] Preferably, the rotating disk is located on the side of the handwheel, and there is a transmission connection between the rotating disk and the handwheel.
[0008] Preferably, one end of the spring away from the power block is fixed to the inner wall of the hydraulic chamber.
[0009] Preferably, when the deceleration assembly is in use, the rubber friction pad is in contact with the friction plate.
[0010] The utility model provides an assembling mechanism for the intermediate body of a series plunger pump. It has the following beneficial effects:
[0011] (1) The intermediate assembly mechanism of this series plunger pump can rotate the rotary table according to the most suitable position of the operator during the tightening process. By replacing the conversion fixture, it can be compatible with other model products. This mechanism solves the difficulty of manual installation and also improves production efficiency and product quality.
[0012] (2) For the intermediate assembly mechanism of this series plunger pump, when the speed of turning the handwheel is too fast, resulting in too fast moving speed of the corresponding front pump fixture or rear pump fixture, with the cooperation of the rotating disc, hydraulic chamber, power block, spring, arc-shaped rod, rubber friction pad and friction plate, the front pump fixture or rear pump fixture can be decelerated to prevent it from hitting the intermediate connection fixture and causing damage, making the device easier to use.

[0020] Embodiment 1
[0021] Please refer to Figures 1 - 3, A combined assembly mechanism for a series plunger pump intermediate body, comprising a base 100. A front pump fixture 200, an intermediate connection fixture 300, and a rear pump fixture 400 are assembled on the top of the base 100. The front pump fixture 200 and the rear pump fixture 400 are symmetrically distributed with respect to the intermediate connection fixture 300. Handwheels 500 for adjusting the position are assembled on the sides of the front pump fixture 200 and the rear pump fixture 400. The three components of the front pump, the intermediate connection, and the rear pump are respectively hoisted onto the front pump fixture 200, the intermediate connection fixture 300, and the rear pump fixture 400. By rotating the handwheel 500, the intermediate connection is docked and assembled with the front pump, and at the same time, an impact wrench is used to pre-tighten the front pump assembly bolts. By rotating the other handwheel 500, the rear pump is assembled with the intermediate connection, and at the same time, an impact wrench is used to pre-tighten the rear pump assembly bolts. In this way, the installation can be completed, improving the production efficiency and product quality.

[0023] Embodiment 2
[0024] Please refer to Figures 1 - 3, on the basis of the first embodiment, a deceleration assembly 600 is provided on the top of the base 100. The deceleration assembly 600 includes a rotating disk 601, and the rotating disk 601 is located on the side of the handwheel 500, and the rotating disk 601 is in a transmission connection state with the handwheel 500. When the speed of rotating the handwheel 500 is too fast, resulting in the corresponding front pump clamp 200 or the rear pump clamp 400 moving too fast, the handwheel 500 drives the rotating disk 601 connected to it in transmission to rotate rapidly. A hydraulic chamber 602 is fixedly connected to the outside of the rotating disk 601. A power block 603 is slidably connected inside the hydraulic chamber 602. A spring 604 is fixedly connected to the side of the power block 603. One end of the spring 604 away from the power block 603 is fixed to the inner wall of the hydraulic chamber 602. An arc-shaped rod 605 is slidably connected to the side of the hydraulic chamber 602. A rubber friction pad 606 is covered on the outside of the arc-shaped rod 605. A friction plate 607 is fixedly connected to the side of the base 100. In the enabled state of the deceleration assembly 600, the rubber friction pad 606 is in contact with the friction plate 607. When the rotating disk 601 rotates rapidly, the rotating disk 601 drives the hydraulic chamber 602 fixedly connected to it to rotate rapidly. The power block 603 in the hydraulic chamber 602 then moves under the action of centrifugal force, stretching the spring 604 and moving inside the hydraulic chamber 602, increasing the pressure inside the hydraulic chamber 602 and driving the arc-shaped rod 605 slidably connected to the hydraulic chamber 602 to move. At this time, the arc-shaped rod 605 moves synchronously during the rotation process, so that the rubber friction pad 606 covered on the outside of the arc-shaped rod 605 moves along with it. At this time, during the rotation process, the rubber friction pad 606 can generate friction with the friction plate 607, thereby decelerating the handwheel 500 and further decelerating the front pump clamp 200 or the rear pump clamp 400, preventing it from hitting the intermediate coupling clamp 300 and causing damage, making the device easier to use.
[0025] During use, on the basis of the first embodiment, when the speed of rotating the handwheel 500 is too fast, resulting in the corresponding front pump clamp 200 or the rear pump clamp 400 moving too fast, the handwheel 500 drives the rotating disk 601 connected to it in transmission to rotate rapidly, so that the rotating disk 601 drives the hydraulic chamber 602 fixedly connected to it to rotate rapidly. The power block 603 in the hydraulic chamber 602 then moves under the action of centrifugal force, stretching the spring 604 and moving inside the hydraulic chamber 602, increasing the pressure inside the hydraulic chamber 602 and driving the arc-shaped rod 605 slidably connected to the hydraulic chamber 602 to move. At this time, the arc-shaped rod 605 moves synchronously during the rotation process, so that the rubber friction pad 606 covered on the outside of the arc-shaped rod 605 moves along with it. At this time, during the rotation process, the rubber friction pad 606 can generate friction with the friction plate 607, thereby decelerating the handwheel 500 and further decelerating the front pump clamp 200 or the rear pump clamp 400.
