Cutting machine for machining gearbox shell

Abstract

The invention discloses a cutting machine for machining a gearbox shell. The cutting machine comprises a base. A cutting plate is arranged on the upper surface of the base. A supporting rod is arranged in the middle of the cutting plate. A motor and a positioning block are arranged on the upper portion of the supporting rod. One end of the motor is fixedly connected with a cutting disk through a rotary shaft. An annular sliding groove is formed in the upper surface of the base. A clamping groove is formed in the middle of the upper surface of the base. An annular sliding block matched with the annular sliding groove is arranged on the lower surface of the cutting plate. A through hole of which the diameter is equal to that of the clamping groove is formed in the middle of the cutting plate. A cutting groove is formed in the upper surface of the cutting plate. According to the cutting machine for machining the gearbox shell, the cutting angle of a workpiece on the cutting plate is adjusted conveniently, the workpiece does not need to be fixed after being dismounted, the cutting accuracy is higher, a plurality of workpieces needing to be cut can be fixed on the cutting plate simultaneously, lots of time, manpower and material resources can be saved, application is more convenient, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a cutting machine for processing a gearbox case. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; Composed of torque converter, planetary gear and hydraulic control system, through hydraulic transmission and gear combination to achieve variable speed and torque, the functions are: 1. Change the transmission ratio; 2. When the engine rotation direction remains unchanged, the car can be reversed Driving; 3. Use the neutral gear to interrupt the power transmission so that the engine can start and idle, and it is convenient for the transmission to shift gears or perform power output. The casing of the transmission is mainly used to protect the internal...

[0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; Composed of torque converter, planetary gear and hydraulic control system, through hydraulic transmission and gear combination to achieve variable speed and torque, the functions are: 1. Change the transmission ratio; 2. When the engine rotation direction remains unchanged, the car can be reversed Driving; 3. Use the neutral gear to interrupt the power transmission so that the engine can start and idle, and it is convenient for the transmission to shift gears or perform power output. The casing of the transmission is mainly used to protect the internal components of the transmission to avoid damage to the components. During the processing of the gearbox housing, the material needs to be cut. The general cutting machine can only cut in one direction. If it is necessary to change the cutting angle, it will be very troublesome, a lot of time is wasted, and the work efficiency is reduced.
