Abstract
Disclosed is a boring machine internal spherical surface tool equipment, which is composed of a boring bar, a fixed block, a slider, a connecting rod, a feed gear wheel, a toolbar and a poking block, the connecting rod is parallel to the boring bar, the fixed block is arranged on the boring bar, a threaded hole parallel to the boring bar is disposed on the fixed block, and a square groove vertical to the threaded hole is arranged on the fixed block, one end of the connecting rod is arranged in the fixed block through a screw thread, the feed gear wheel is disposed on a section of the connecting rod corresponding to the square groove, the toolbar is connected with the boring bar and the connecting rod through a first pin shaft and a second pin shaft, and a boring cutter is arranged on one end of the toolbar, a slider is disposed at the middle part of the connecting rod, the slider is covered-jointed on the boring bar, and the poking block is fixedly arranged on a work table of the boring machine and is matched with the feed gear wheel. The utility model combines a four-bar mechanism and a thread mechanism into the boring machine tool equipment, and realizes the feed motion of the boring cutter through driving the link mechanism by means of a screw thread pair; and the tool equipment has advantages of convenient application, high machining efficiency, being capable of machining the internal spherical surface on the boring machine accurately and extending the range of application of the machine tool.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to boring machine, particularly a kind of boring Internal Spherical Surface frock.
Background technology:
Often need on boring machine, be processed with the part of Internal Spherical Surface in the production,, must the design specialized frock just can finish the processing of Internal Spherical Surface because boring machine itself does not have the function of boring Internal Spherical Surface.In the prior art.The special tooling complex structure, the working (machining) efficiency that are adapted at processing Internal Spherical Surface on the boring machine are low, and perhaps machining accuracy is low, can not adapt to economical production and meet design requirement.
Summary of the invention:
The purpose of this utility model provides a kind of boring Internal Spherical Surface frock, and described this boring Internal Spherical Surface frock will solve the technical problem that special tooling complex structure, working (machining) efficiency are low, machining accuracy is low of processing Internal Spherical Surface in the prior art on the boring machine.
This boring Internal Spherical Surface frock of the present utility model is made of a boring bar and workbench, wherein, be set with a fixed block on the described boring bar, described fixed block is arranged on a side of workbench, what be parallel to boring bar in the fixed block axially is provided with screwed hole, axially be provided with square groove perpendicular to described screwed hole in the fixed block, be provided with a connecting rod in the screwed hole, described connecting rod is provided with screw thread, be provided with feed gear wheel in the described square groove, the center of circle of described feed gear wheel is provided with an internal thread hole, screw-threaded engagement on described internal thread hole and the connecting rod, be set with a shifting block on the workbench, the tooth movement locus of described shifting block and feed gear wheel intersects, and an end of boring bar is connected with a knife bar by first bearing pin, described knife bar is connected with connecting rod by second bearing pin, be set with a slide block on the connecting rod, be provided with through hole in the described slide block, slide block is set on the boring bar by described through hole.
Further, an end of described knife bar is provided with boring cutter.
Further, described slide block is connected with described connecting rod by housing screw.
Further, described fixed block is connected with described boring bar by housing screw.
Operation principle of the present utility model is: boring bar is installed in the boring machine, and the sphere centre coincidence with workpiece is adjusted at the center of first bearing pin.When boring bar rotates, driving boring cutter by knife bar moves in a circle, move in a circle by slide block and fixed block drivening rod simultaneously, axial displacement does not take place in boring bar, boring bar is in the process of rotating a circumference, feed gear wheel is through once being fixed on the shifting block on the workbench, feed gear wheel is stirred a tooth by shifting block, feed gear wheel rotates, and by the internal thread hole drive link in the feed gear wheel along its axial advancement, connecting rod promotes knife bar by second bearing pin and rotates around first bearing pin, realizes the processing of workpiece Internal Spherical Surface.The size of the boring cutter amount of feeding is decided by the pitch size of interlinking lever end and the number of teeth of feed gear wheel.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model just quadric chain and thread mechanism phase structure is applied in the boring machine frock, by screw thread pair drive link mechanism, realizes the feed motion of boring cutter; Easy to use, working (machining) efficiency is high, can accurately process Internal Spherical Surface on boring machine, enlarges the scope of application of lathe.
