Three-sided drilling and tapping machine for wiper motor gearbox

Abstract

The invention discloses a three-sided drilling and tapping machine for a wiper motor gearbox. The three-sided drilling and tapping machine comprises a machine tool rack. Main shaft boxes are perpendicularly distributed on the machine tool rack in three directions and connected with motors and pneumatic feeding mechanisms of the main shaft boxes. The motors and the pneumatic feeding mechanisms are connected with an electronic control cabinet. The electronic control cabinet is connected with an operating console and a CNC system. Main shafts are arranged in the main shaft boxes. Each main shaft is provided with multiple small shaft heads. The motors drive the main shafts to rotate through transmission mechanisms. The pneumatic feeding mechanisms control the main shaft boxes to be fed forwards and backwards relative to the motor gearbox, and the small shaft heads are driven by multiple gear transmission mechanisms to rotate in the main shafts. A cooling distribution system is arranged above the main shafts. An inclined chip groove is formed in the lower end face of the machine tool rack. A cooling pump system is arranged at the tail end of the chip groove. A workpiece locking mechanism is arranged on the machine tool rack in another direction. The three-sided drilling and tapping machine can conduct drilling and tapping on three surfaces of the gearbox at the same time, in this way, the production efficiency is high, the position precision of the workpiece is high, and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the field of machining and manufacturing, and particularly relates to a three-sided drilling and tapping machine for a wiper motor gearbox. Background technique [0002] In machine tools and some complex mechanical devices, the gearbox is an important mechanical component. Since the function of the gearbox is to transmit the rotational speed, the drilling and tapping process of the gearbox is a very important part of the gearbox processing process. . [0003] Gearbox drilling and tapping are generally processed by a drilling machine. Since the gearbox needs to perform drilling and tapping operations on three surfaces, three processes, three sets of equipment and three The tooling needs to be fixed several times, resulting in low production efficiency, high energy consumption, poor workpiece position accuracy, and high manufacturing costs. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a...
