Description
Technical field
The present invention relates to a kind of drilling and milling machine drive technology field, especially a kind of apparatus for fast switching of drilling and milling machine strap speed varying.
Background technology
The kind of drive of the main shaft speed change of current drilling and milling machine is by gear drive and belt transmission two kinds of modes.Gear-driven throw-over is easy to operate, is converted by handle, can be switched to rapidly required speed.But gear-driven milling machine is common exists noise problem, higher to the requirement of Gear Processing.Portioned product adopts nylon gear to reduce noise, but greatly reduces working strength, and often have disrepair phenomenon, maintenance rate is high.Use bel-drivenn drilling and milling machine to be realize different rotating speeds by the belt pulley set of multilayer different-diameter is incompatible in prior art, but replacing belt bother very much in the position of different belt pulley.First the transmission mechanism of belt must protect with case, and the position changing belt needs first to open case, and then belt is unloaded down from original pulley position, change to new pulley position.Whole operation is very loaded down with trivial details, needs to take a lot of time.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of apparatus for fast switching of drilling and milling machine strap speed varying, can solve the deficiencies in the prior art, can realize the conversion of speed fast and easily, and does not need dismounting belt case.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of apparatus for fast switching of drilling and milling machine strap speed varying, comprise casing, in described casing, taper roller bearing is provided with main shaft, spline housing is socketed with outside main shaft, spline housing arranged outside has deep groove ball bearing, deep groove ball bearing is fixed in casing by bearing block and bearing gland, spline housing takes turns selective connection with high speed belt wheel and weathering zone under the drive of clutch, clutch is connected with the axis of guide, the axis of guide is connected to clutch shaft by shift fork, casing internal fixtion has motor, the output shaft of motor is provided with driving pulley, driving pulley engages with low speed belt and high-speed belt respectively, low speed belt engages with low speed belt wheel simultaneously, high-speed belt engages with high speed belt wheel simultaneously.
As preferably, the top of described main shaft is provided with dust cap.
As preferably, the arranged outside of described main shaft has rack sleeve.
As preferably, described rack sleeve engages with gear shaft, and gear shaft is connected with handle set and helical gear respectively, and helical gear is connected with worm screw.
As preferably, the outside of described clutch shaft is socketed with lining.
The beneficial effect adopting technique scheme to bring is: the present invention realizes the switching between different belt speed by arrangement of clutch.Motor pulley and spindle pulley remain connection by belt, and ordinary straps can be used to take turns and V belt, multiple ribbed pulley and multi-rib-belt or synchronous pulley and Timing Belt.What adopt in this programme is the cooperation of synchronous pulley and Timing Belt, can ensure that the running of motor and main shaft is out-of-step free, reach completely with gear-driven effect.Main shaft is spline structure or a band keyway, and the rotation of main shaft is realized with being engaged of belt pulley of high low speed by the engagement belt wheel of a slippage.Belt pulley is connected by bearing with main shaft, and the rotating speed of belt pulleys different so does not affect the rotating speed of main shaft.An end face of belt pulley processes teeth groove, and the teeth size engaged with centre on belt wheel coordinates.The rotating speed of belt pulley just can must be delivered on main shaft by the occlusion of engaging belt wheel with centre.As long as make engagement belt wheel link from different belt pulleys like this, main shaft just can be allowed to realize different speed.This process is realized by clutch shaft, operates fast very convenient.The present invention thoroughly solves the loaded down with trivial details variable speed operation of the drilling and milling machine of strap speed varying, maintains belt transmission relative to gear-driven quiet running.Also reach gear transmission structure variable speed operation efficiently simultaneously.
