Description
The utility model relates to a kind of metal rack tooth punching machine.
Present domestic textile equipment industry is processed the tooth that dashes of metal rack, adopt old-fashioned tooth punching machine always, new breakthrough is not all arranged in design decades, after old-fashioned tooth punching machine main shaft assembles with drift, the end face run-out value that connects end face surpasses 0.005mm, and the circular runout value of the periphery of main shaft is lower greater than the 0.005mm precision.The axiality in front and back bearings hole is low, and general axiality is about 0.01mm, and processing difficulties, axiality be cannot say for sure to demonstrate,prove.Can't adjust the bearing clearance after the general assembly, influence assembly precision, preloaded bearing must all remove casing with main shaft and parts on shaft, keeps in repair a precision and reduces once.Drift installs one cutter, towards tooth speed less than per minute kind 5000 times, lubricated often because of the obstruction of nozzle and in short-term oil starvation cause the damage of bearing, gearratio is inaccurate, drift turns round inhomogeneous.Exist efficient low, profile of tooth varies, and the racks processed precision is low, defectives such as quality instability.
The purpose of this utility model is to propose a kind of and metal rack tooth punching machine that precision high fast towards tooth speed.
The purpose of this utility model is achieved in that the metal rack tooth punching machine, have casing and main shaft, have spindle hole in the casing, fore bearing hole and rear bearing hole, drift is installed on the main shaft successively, fore bearing, the bearing pre-tightened device, rear bearing and transmission device, main shaft is installed in the spindle hole of casing, and be fixed in the casing by fore bearing and rear bearing, the bearing pre-tightened device is made up of axle sleeve and pre-load nut, casing top has pouring orifice, the bottom has oil-out, installs on the drift towards the serrated knife tool, installs two on the drift towards the serrated knife tool, the fore bearing hole, spindle hole and rear bearing hole connect and are same hole, and casing top has the adjustment hole that can regulate pre-load nut.
In most preferred embodiment of the present utility model:
Described oil-out has with a certain distance from casing spindle hole lower end.
Described transmission device is that camber is with transmission synchronously.
The utility model has the advantages that fast towards tooth speed, precision is high, gearratio is accurate, easy to maintenance.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of old-fashioned metal rack tooth punching machine.
Metal rack tooth punching machine as shown in Figure 1, have casing 1 and main shaft 2, have spindle hole 3 in the casing 1, fore bearing hole 4 and rear bearing hole 5, drift 6 is installed on the main shaft 2 successively, fore bearing 7, bearing pre-tightened device 8, rear bearing 9 and transmission device 10, main shaft 2 is installed in the spindle hole 3 of casing 1, and be fixed in the casing 1 by fore bearing 7 and rear bearing 9, bearing pre-tightened device 8 is made up of axle sleeve 11 and pre-load nut 12, casing 1 top has pouring orifice 13, the bottom has oil-out 14, installs two on the drift 6 towards the serrated knife tool, reaches per minute 10000 times towards tooth speed, fore bearing hole 4, spindle hole 3 and rear bearing hole 5 connect and are same hole, improved the axiality of dead eye, axiality has been simplified technology less than 0.003mm, reduced processing cost, casing 1 top has the adjustment hole 15 that can regulate pre-load nut 12, can adjust the gap and the pretightning force of the high-precision bearing of main shaft 2 arbitrarily, has improved the precision of assembling, easy to maintenance, do not influence assembly precision after the maintenance.Oil-out 14 has with a certain distance from the lower end of the spindle hole 3 of casing 1, can because of the obstruction of nozzle and in short-term oil starvation cause the damage of bearing, transmission device 10 is with transmission synchronously for camber, gearratio is accurate, running is even.
