It is usually composed of a frame, a work surface, positioning tools, fixtures, etc. The surface of the work table is generally made of steel plates, which have strong corrosion resistance and a certain cushioning and wear resistance on the surface to ensure the accuracy and stability of the assembly. The fixing devices and adjustment devices can be changed accordingly according to work needs. The assembly table is widely used in various machinery manufacturing industries, such as bearings, pumps, motors, etc. During use, attention should be paid to production safety, accidental injuries should be avoided, and regular maintenance should be performed to ensure the normal operation of the equipment and extend its service life.

[0011] By adopting the above technical solution, when in use, the staff places the casing of the axial flow fan inside the placement plate through the loading and unloading components. During this process, the self-generated gravity of the axial flow fan casing will squeeze the second pressure block, and then the squeezed second pressure block moves downward to drive the positioning plate to rotate, and then the rotating positioning plate will drive the third connecting column to move and squeeze the return spring inside the second mounting tube. At the same time, the rotation of the positioning plate will drive the first pressure block to move downward, so as to quickly clamp and fix the axial flow fan casing when it is placed. After the above steps are completed, the staff places the fan blade shaft inside the first mounting tube and clamps it through the rebound force of the two second springs and the two clamping plates. During this process, the staff can pull the adjusting block, and then the adjusting block is pulled to drive the first connecting column to squeeze the third spring, and at the same time, multiple second limit blocks will move out from the inside of multiple second limit grooves, and then the staff can rotate the adjusting block to drive the gear to rotate, and then under the gear and rack tooth meshing transmission action, the connecting block will drive the connecting rod and the adjusting tube at its top and the mounting head to adjust the height up and down. , so that the concentricity of the fan blade shaft inside the first installation tube and the axial flow fan housing can be kept consistent.

After the above steps are completed, the staff can rotate the mounting head 42 to drive the fan shaft to rotate, and then the staff can install multiple fan blades on the fan shaft, and then the staff can rotate the adjusting screw 41 to drive the mounting head 42 and the assembled fan shaft into the interior of the axial flow fan housing for fixing through threaded transmission. In this process, since the concentricity between the fan shaft and the fan housing is adjusted, and the fan shaft is always kept in the process of movement. The original height can be maintained, and the concentricity of the fan blade shaft and the fan casing can be maintained when they are installed and fixed. After the above steps are completed, the staff can move the installation head 42 out from the inside of the fan casing, and rotate the adjustment plate 3 through the two adjustment rods 18, so that the fan casing on the top of the adjustment plate 3 can be turned, and then the staff can install the motor inside the fan casing, and install the two dustproof nets at both ends of the fan casing by rotating upward, so as to achieve the assembly of the axial flow fan, and facilitate the concentricity of the fan blade shaft and the motor shaft during assembly, thereby improving the assembly efficiency of axial flow fans of the same model.
