Internal puller for differential gear
Characteristics of Internal Broaching Machines for Differential Gears:
High Rigidity: The machine bed, slide, and fixture possess extremely high rigidity to withstand the immense broaching force and ensure machining accuracy.
High Pulling Force: A sufficiently large pulling force is required to drive the broach to complete the cutting process, especially when machining splines of larger dimensions or modules. The pulling force typically ranges from tens to hundreds of tons.
Precise Guiding: Extremely high precision is required for guiding the broach and workpiece to ensure the relative positions of the tool and workpiece are accurate during broaching, avoiding taper, deviation, or tooth profile errors.
High-Efficiency Fixture: Equipped with a dedicated fixture for quick clamping and precise positioning to adapt to the shape of the gear and enable quick loading and unloading (often integrated with an automated loading and unloading system).
Cooling System: Provides sufficient, high-pressure cutting fluid (usually oil-based) for cooling the tool and workpiece, lubricating the cutting zone, and flushing away chips.
Control System: Modern broaching machines are equipped with CNC systems or PLC control to precisely control the broaching stroke length, speed, return speed, and auxiliary actions (clamping, releasing, feeding, etc.), and may integrate tool life management and process monitoring functions.
An "internal broaching machine for differential gears" is a specialized metal-cutting machine tool designed and optimized to meet the high-precision, high-efficiency, and mass production needs of internal spline bores in automotive differential planetary gears and half-shaft gears. It utilizes specially designed precision broaches, using a single powerful linear broaching stroke to quickly and accurately form complex internal involute spline tooth profiles. It is an indispensable piece of equipment in the manufacturing of key components in automotive transmission systems. This broaching machine uses a servo motor to drive a high-strength, impact-resistant screw, driving the main slide to move on the guide rail. It has the advantages of high precision, high stability, high wear resistance, and simple maintenance. It is used in the automotive, engineering machinery, and wind power industries, and has been widely used in the field of new energy vehicles, such as in the processing of differential gears, motor shafts, and transmission gear components.
