Description

Technical Field

[0001] The utility model belongs to the field of gear pumps and is particularly designed to provide a gear pump assembly platform. Background Art

[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume created between the pump cylinder and meshing gears to transport or increase pressure. It consists of a driving shaft, a driven shaft, a pump body, and front and rear covers, forming two enclosed chambers. As the gears rotate, the volume of the chamber on the side where the gears are disengaged increases from smaller to larger, creating a vacuum that draws in the liquid.

[0003] During the gear pump processing, its components need to be processed separately. After the processing of each component is completed, they are assembled to form the gear pump as a whole. During the gear pump assembly process, manual installation is usually adopted. When installing the locating bearing, the locating bearing is usually hammered into the locating shaft hole by manual hammering. However, the locating bearing is easily damaged during the hammering process, affecting the use of the gear pump. Utility Model Content

[0004] The utility model provides a gear pump assembly platform, which aims to improve the problem of damage to positioning bearings caused by hammering during the installation of the gear pump.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a gear pump assembly platform, including a table and a supporting platform; there are two supporting platforms, namely a front pump cover supporting platform and a rear pump cover supporting platform, and a supporting plate is provided above the rear pump cover supporting platform; the front pump cover supporting platform includes a front block seat, a flat supporting plate is provided on the front block seat, and an internal pressure component is provided on the flat supporting plate;

[0006] Furthermore, a flippable support arm is provided on the table, one end of the support arm is provided with an end stop plate, a fixedly connected drive rod is provided on the end stop plate, and a clamping claw is provided under the drive rod, which can clamp the shaft to be installed. When the support arm is flipped from a horizontal state to a vertical state, the shaft to be installed is located above the pump casing.

[0007] Furthermore, the supporting plate is L-shaped, and the supporting plate is hinged to the rear pump cover supporting platform.

[0008] Furthermore, a support column is provided on one side of the vertical portion of the supporting plate close to the pump body, and a roller is provided on the other side.

[0009] Furthermore, a fixedly connected support arm is provided on the supporting arm, the support arm and the supporting arm are perpendicular to each other, and a through hole is provided in the center of the support arm.

[0010] Furthermore, a flip component is provided inside the rear pump cover supporting platform, and the flip component is hinged to the lower surface of the supporting plate and the inside of the rear pump cover supporting platform respectively.

[0011] Furthermore, the front stop seat is provided with a center hole, and the driving shaft is coaxially arranged with the center hole.

[0012] Compared with the prior art, the present invention has the following advantages: the present invention has a simple structure and is easy to use; during the installation process, it only needs to install the driving shaft or the driven shaft on the supporting arm, so that quick assembly can be achieved, thereby improving the efficiency and convenience of assembly;

[0013] In addition, in the past, the installation of the locating bearing required manual use of a hammer to hammer the locating bearing into the locating shaft hole. Due to the instability of manual labor, the locating bearing was easily damaged during the hammering process. Compared with the method of hammering the locating bearing, the utility model uses the internal pressure component to push the locating bearing, making the docking of the locating bearing and the front pump cover more stable and safe, and will not cause damage to the locating bearing.
