A kind of grinding machine for processing valve lock clip groove

Abstract

The invention discloses a special collet groove grinding machine for machining a valve. The special collet groove grinding machine comprises a base, a guide base, a side fixing plate, a guide groove,a guide seat, a longitudinal screw rod, a longitudinal stepping motor, a grinding device, clamping transmission devices, a connecting gear, a shell, a connecting seat, a driving gear and a driving motor. The special collet groove grinding machine has the advantages that the structure is reasonable and simple, the plurality of clamping transmission devices are arranged, so that the multiple valvescan be clamped so as to be ground sequentially, and the grinding efficiency is improved; through the longitudinal stepping motor, the grinding device and the connecting gear can be driven to vertically move to the right lower side of the corresponding clamping transmission device, so that the corresponding valve can be subjected to grinding machining; in addition, the valves can be replaced afterthe grinding is completed, so that the machining efficiency is further improved; and the longitudinal stepping motor and a vertical stepping motor are both stepping motors, so that accurate control can be carried out through the existing technology, and the grinding quality and precision are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a special lock clamp groove grinder for processing valves. Background technique [0002] The valve is an important part of the engine, which is responsible for inputting air into the engine and discharging the exhaust gas after combustion. From the structure of the engine, it is divided into intake valve and exhaust valve. The function of the intake valve is to suck air into the engine. Mixed combustion with fuel, the function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat, so the function of the valve in the engine is obvious. In the actual processing and production process, there are high requirements for the product, and the valve needs to be adjusted Many processes are carried out, and an important step is to grind the valve. The existing valve lock groove is turned on a lathe, but the surface roughness is rela...

[0002] The valve is an important part of the engine, which is responsible for inputting air into the engine and discharging the exhaust gas after combustion. From the structure of the engine, it is divided into intake valve and exhaust valve. The function of the intake valve is to suck air into the engine. Mixed combustion with fuel, the function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat, so the function of the valve in the engine is obvious. In the actual processing and production process, there are high requirements for the product, and the valve needs to be adjusted Many processes are carried out, and an important step is to grind the valve. The existing valve lock groove is turned on a lathe, but the surface roughness is relatively large, especially the intake valve. The material of the intake valve is soft, and the processing traces are relatively large, resulting in flaws on the appearance of the valve, which will affect the later use effect
