Abstract
本实用新型技术是一种单缸柴油机曲轴连杆颈车削加工专用夹具。主要是由支座、配重块、三爪卡盘过渡盘、圆柱头内六角螺钉、弹簧垫圈、定位杆、定位销、调整垫块、M20六角扁螺母等组成。单缸柴油机曲轴短头放入三爪卡盘过渡盘的孔内，通过支座的定位杆定位，方便、快捷地在车床上定位好，使得单缸柴油机曲轴的连杆颈轴线在车床主轴线上。本实用新型能方便、快捷地在车床上装夹单缸柴油机曲轴，进行单缸柴油机曲轴连杆颈车削加工，提高了生产效率，避免了专用机床的设计，降低了生产厂商的生产成本。
The utility model technology is a special fixture for turning and processing the crankshaft connecting rod neck of a single-cylinder diesel engine. It is mainly composed of support, counterweight, three-jaw chuck transition plate, cylindrical head hexagon socket head screw, spring washer, positioning rod, positioning pin, adjusting pad, M20 hexagonal flat nut, etc. Put the short head of the crankshaft of the single-cylinder diesel engine into the hole of the transition plate of the three-jaw chuck, and position it on the lathe through the positioning rod of the support, so that the connecting rod neck axis of the crankshaft of the single-cylinder diesel engine is on the main axis of the lathe superior. The utility model can conveniently and quickly clamp the crankshaft of the single-cylinder diesel engine on the lathe, and turn the connecting rod neck of the crankshaft of the single-cylinder diesel engine, thereby improving the production efficiency, avoiding the design of a special machine tool, and reducing the production cost of the manufacturer.
Description
Technical field
The utility model technology is a kind of crank-shaft link neck of single-cylinder diesel engine turning Special Fixture for Machining.
Background technology
Traditional crank-shaft link neck of single-cylinder diesel engine is processed, and requires the machining tool of design special, has increased processing cost for Production of Crankshaft manufacturer.The utility model is clamping one-cylinder diesel machine crankshaft on lathe quickly and easily, carries out crank-shaft link neck of single-cylinder diesel engine turning processing, has improved production efficiency, has avoided the design of special purpose machine tool, has reduced the production cost of production firm.
Summary of the invention
The purpose of the utility model is to utilize a kind of crank-shaft link neck of single-cylinder diesel engine turning Special Fixture for Machining; Clamping one-cylinder diesel machine crankshaft on lathe quickly and easily; Carry out crank-shaft link neck of single-cylinder diesel engine turning processing; Improve production efficiency, avoided the design of special purpose machine tool, reduced the production cost of production firm.
The technical scheme that the utility model adopts is: mainly be made up of bearing, balancing weight, scroll chuck transition disc, socket cap screw, spring washer, backstay, alignment pin, adjustment cushion block, M20 hexagon thin nut etc.Transition disc is fixed on the lathe spindle; Transition disc and scroll chuck transition disc connect into integral body through socket cap screw; Bearing and scroll chuck transition disc are accurately located through alignment pin; Be connected with spring washer through socket cap screw, the adjustment pad is arranged between backstay and the bearing and be fixed on the bearing by the M20 jam nut.Next hole is stayed in the position of a single cylinder diesel crankshaft eccentric of off center distance on the scroll chuck transition disc; The connecting rod neck axis of one-cylinder diesel machine crankshaft is on the lathe spindle line when machined into like this; For the power on the balance scroll chuck transition disc; Opposite side in the hole is fixed on balancing weight on the scroll chuck transition disc through socket cap screw, makes integral body be among the static balance.
The beneficial effect of the utility model is: clamping one-cylinder diesel machine crankshaft on lathe quickly and easily; Carry out crank-shaft link neck of single-cylinder diesel engine turning processing; Improve production efficiency, avoided the design of special purpose machine tool, reduced the production cost of production firm.
