Description
Technical field
The utility model relates to the technical field, particularly a kind of blind hole tapping machine of machining internal thread in blind hole.
Background technology
At present, the method that blind hole is attacked internal thread is: first revolving parts is arranged on the chuck on lathe, then bore cutter is installed on tailstock, start lathe, chuck rotates, and now mobile tailstock processes blind hole, processes after blind hole, take out bore cutter and use screw tap instead, now mobile tailstock makes the blade of screw tap process internal thread on blind hole inwall again.But; chuck conventionally can be because the centrad error of the wearing and tearing of the catching of the vibrations of lathe, chuck, chuck axis be large and the factor such as the interference of extraneous factor; cause being sandwiched in the axis of the revolving parts on chuck and the axis of chuck does not overlap; thereby there is the phenomenon that part swings; finally cause the nominal diameter error of internal thread large; thereby can only be used as waste disposal, have a strong impact on the economic benefit of enterprise.And, after the complete blind hole of every brill, need again the bore cutter on tailstock to unload installation screw tap, bring inconvenience to operative employee, reduce production efficiency.
In addition, the tapping of blind hole is larger than the tapping degree-of-difficulty factor of through hole, the difference of the tapping of blind hole and the tapping of through hole is: when the internal tapping of screw tap processing blind hole, the web-like iron filings that produce in tapping process are deposited in blind hole and are difficult to discharge, cannot there is heat exchange with the external world in the heat in metal cutting producing while causing cutting metal, thereby cause the cutting temperature in blind hole very high, heavy wear the blade on screw tap, shortened the working life of screw tap, attack blind hole internal thread to operating personnel has increased difficulty simultaneously.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, processing blind hole internal thread precision is high, can effectively avoid screw tap wearing and tearing, easy and simple to handle, the blind hole tapping machine of enhancing productivity.
The purpose of this utility model is achieved through the following technical solutions: a kind of blind hole tapping machine, it comprises chuck, reduction box, motor and workbench, motor and reduction box are all fixedly mounted on workbench, motor is connected with reduction box, described chuck is parallel to workbench setting and chuck is connected with reduction box, it also comprises slip crate, slide block, guide rail I, controller, tailstock and automatic aligning tailstock, described controller is connected with motor, described guide rail I is parallel to chuck setting and guide rail I is fixedly mounted on workbench, described slip crate bottom is provided with the chute I matching with guide rail I, slip crate top is installed with the guide rail II arranging perpendicular to guide rail I, slip crate is matched and is arranged on guide rail I with guide rail I by chute I, described slider bottom is provided with the chute II matching with guide rail II, slide block is matched and is arranged on guide rail II with guide rail II by chute II, described tailstock and automatic aligning tailstock are all parallel to guide rail I setting and tailstock and automatic aligning tailstock and are all fixedly mounted on slider top, in described automatic aligning tailstock, be provided with automatic aligning sliding bearing, in described tailstock, be provided with sliding bearing.
On described workbench, be installed with two guide rail I that be arranged in parallel.
Described guide rail I and guide rail II are all swallowtail shape.
The utlity model has following advantage: (1) guide rail I of the present utility model is parallel to chuck setting and guide rail I is fixedly mounted on workbench, tailstock and automatic aligning tailstock are all parallel to guide rail I setting and tailstock and automatic aligning tailstock and are all fixedly mounted on slider top, in automatic aligning tailstock, be provided with automatic aligning sliding bearing, in tailstock, be provided with sliding bearing, before machining internal thread, first screw tap is arranged in automatic aligning sliding bearing, bore cutter is arranged in sliding bearing, part to be processed is clamped by chuck, sliding slider is also moved to the left slip crate, the point of a knife of bore cutter is withstood on the end face of part, thereby complete the tool setting process of bore cutter, then at controller control electric machine rotation, the torque of motor is delivered on chuck through reduction box, chuck rotates, now, continue to slide slip crate left, thereby complete the lead plug of blind hole, after blind hole machines, sliding slider is also adjusted slip crate, the blade of screw tap is leaned against on the inwall of blind hole, thereby complete the process of tool setting, now, continued to slide slip crate left, thereby complete the tapping of blind hole, reinstall screw tap without the bore cutter on tailstock is unloaded, brought convenience to like this operative employee's work, improved production efficiency and production output.(2) automatic aligning sliding bearing shape spherical in shape, after the handle of a knife of screw tap is arranged in automatic aligning sliding bearing, screw tap can swing in automatic aligning tailstock, therefore, the axis of screw tap in the time attacking internal thread, the axis of screw tap all the time with the dead in line of chuck, therefore can not be subject to the impact of the swing of chuck, thereby make the nominal diameter error of internal thread little, improved the machining accuracy of internal thread, improved the qualification rate of product.(3) controller control motor reversal and slip crate is moved right, web-like iron filings in blind hole can be taken out of with screw tap, therefore, when having attacked after half internal thread, make controller control motor reversal and slip crate is moved right, thereby prevent that web-like iron filings bulk deposition from, in blind hole, can effectively avoid the wearing and tearing of screw tap blade, extended the life-span of screw tap.
