Abstract

The invention discloses a plunger rotary-assembling machine. The plunger rotary-assembling machine comprises a machine frame. One end of the machine frame is slidably connected with a movable workbench through a sliding rod and a transmission lead screw. A supporting frame is fixedly arranged at the other end of the machine frame. A rotary shaft is rotatably arranged on the supporting frame through a rolling bearing. A chuck is arranged on the rotary shaft. The transmission lead screw and the rotary shaft are separately connected with a rotary motor and a servo motor. According to the plungerspin-assembling machine, a to-be-assembled cylinder body is fixed to the movable workbench, a plunger is mounted on the chuck, the chuck drives the plunger to rotate, the movable workbench drives theto-be-assembled cylinder body to move linearly, and then the plunger is rotatably assembled into the to-be-assembled cylinder body; and the assembling efficiency is high, the assembling difficulty isgreatly lowered, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of general machinery, in particular to a plunger screwing machine. Background technique [0002] As the core component of the plunger pump, the plunger is slidingly assembled in the cylinder of the plunger pump. When the plunger is pulled back, the valve of the outlet pipe is closed and the valve of the inlet pipe is opened, and the fluid is sucked into the cylinder from the inlet pipe. In the process, when the plunger moves forward, the valve of the inlet pipe is closed and the valve of the outlet pipe is opened, the fluid in the cylinder is pressed and sent out from the outlet pipe, the plunger reciprocates continuously in the cylinder, and the fluid flows continuously. This is the function of the plunger. Generally, the plunger is mainly used in places with high working pressure, and other mechanisms are used in places with low pressure. Therefore, the assembly accuracy of the plunger has a great influenc...
