Pressing mechanism of a slurry pump

Abstract

This utility model discloses a press-fitting mechanism for a slurry pump, relating to the field of slurry pump manufacturing technology. It includes a support and a positioning assembly. A cylinder is mounted on the top of the support, and an mounting plate is installed at the bottom of the cylinder. A punch head is mounted on the bottom of the mounting plate. A guide cylinder is installed inside the support, and a guide rod is inserted into the guide cylinder. A clamping plate is mounted on the top of the guide rod. This press-fitting mechanism for the slurry pump uses a servo motor to drive the drive shaft and the drive gear to rotate. The drive gear drives the driven gear ring to rotate, and simultaneously, the drive gear and driven gear mesh with the gear frame, causing the roller frame and positioning roller to converge synchronously towards the center. This allows for adaptive clamping of pump shafts of different specifications. Furthermore, the positioning rollers are mounted on the openings on both sides of the roller frame via bearings, allowing for flexible rotation. This provides guidance for subsequent pump shaft press-fitting while clamping the pump shaft, ensuring coaxiality between the pump shaft and the pump casing shaft hole and preventing tilting.
