Description
Technical field
The invention belongs to field of mechanical technique, relate to the organisation of working on a kind of instrument lathe, the prism working mechanism on particularly a kind of instrument lathe.
Background technology
Instrument lathe can be processed various workpieces, comprising prism.Prism working mechanism on the existing instrument lathe generally includes the turning cylinder be located on the spindle stock, is connected in cutter, work holder on the turning cylinder.The instrument lathe that has this organisation of working need be clamped in blank on the work holder when the processing prism body, and makes blank keep stable, and cutter mills out several faces of prism on blank then, finally is processed into prism.
Above-mentioned this instrument lathe has its defective when the processing prism body, at first, and owing to several faces on the prism are come out by cutter milling successively, rather than disposable shaping, the process velocity of prism is slow.Secondly, not in place if cutter or blank are adjusted when the different prisms of processing surface, have deviation between each face on the prism that is processed to form, the whole machining accuracy of prism is wayward.
Summary of the invention
The objective of the invention is the existing above-mentioned defective of prism working mechanism at existing instrument lathe, a kind of prism working mechanism of novel instrument lathe is provided, it is adding man-hour to prism, and operation is saved, and process velocity is fast, and the machining accuracy height.
Purpose of the present invention can realize by following technical proposal: a kind of prism working mechanism of instrument lathe, be arranged on the frame of lathe, comprise the turning cylinder be located on the spindle stock, with the joining cutter of turning cylinder, work holder, work holder comprises mutual socket main shaft and trombone slide together, the head circle of the trombone slide chuck of ining succession, it is characterized in that, on described turning cylinder, be fixed with the dish type cutterhead, on the outer peripheral face of this cutterhead, be provided with a cutter at least; Described turning cylinder drives main shaft by gear-driven mode and rotates; Described work holder is located on the upper slide rest of instrument lathe.
Above-mentioned instrument lathe is when the processing prism body, and blank is clamped on the chuck, and is delivered to the position of cutterhead by chuck.Cutter is rotated under the drive of turning cylinder, and blank also rotates under the effect of travelling gear, main shaft, chuck, and cutter and blank rotate simultaneously, by the setting to travelling gear, can determine the relative angle speed between cutter and the blank.When the cutter on the cutterhead turned to the blank position, the processed part on the blank will be carried out milling by cutter, and cutter is when leaving cogging material position, on the blank can not be processed part will turn to cutter.Move in circles like this, work holder is arranged on the upper slide rest in addition, and upper slide rest can be with blank laterally to move, to reach the purpose of processing.This mechanism only needs a procedure just can realize the processing of prism, has reduced the middle operation of adjusting of existing instrument lathe, and process velocity is fast, and the deviation between each face is little on the prism, the machining accuracy height of prism.
In this prism working mechanism, the frame of described lathe is provided with a transversely movable saddle, described upper slide rest is located on the saddle, upper slide rest can vertically move with respect to saddle, is provided with a stopping means adjustable, that the restriction upper slide rest vertically moves scope on upper slide rest.The saddle that is provided with, and upper slide rest can vertically move with respect to saddle, at instrument lathe prism is added man-hour like this, can control the milling amount to blank, thereby can process multiple different size prism, increase the adaptation scope of instrument lathe.
In this prism working mechanism, described stopping means mainly is made up of the screw rod that is fixed on backer on the saddle, be connected with upper slide rest, passes the open-work on the backer screw clearance, and nut has been threaded on the traversing through end of screw rod.By the nut on the turn screw rod, can control the maximum that upper slide rest vertically moves on saddle, thereby can reach the purpose of accurate processing prism body size.
In this prism working mechanism, on saddle, be fixed with gear box A, on upper slide rest, be fixed with gear box B; Be socketed with drive bevel gear on the described turning cylinder, this drive bevel gear is circumferentially fixed and can be moved axially with respect to turning cylinder, and described drive bevel gear is positioned at gear box A; Described trombone slide passes gear box B, and is fixed with driven wheel of differential in gear box B, on the trombone slide; Power transmission shaft passes gear box A and gear box B respectively, be respectively equipped with the Intermediate bevel gears one that is meshed with drive bevel gear, the Intermediate bevel gears two that is meshed with driven wheel of differential at the two ends of power transmission shaft, Intermediate bevel gears one is connected on the power transmission shaft, and Intermediate bevel gears two can move axially on power transmission shaft and be circumferentially fixing with respect to power transmission shaft.In gear-box, can add lubricating oil, for the work of various bevel gears provides lubrication, to improve the service life of each bevel gear.Gear box A is followed saddle and horizontal when mobile, and drive bevel gear is also followed together and moved laterally; Gear box B is when vertically moving, and Intermediate bevel gears two is also followed together and vertically moved.Structure between drive bevel gear and the turning cylinder, and the structure between Intermediate bevel gears and the power transmission shaft makes that the blank on the chuck can be more swimmingly and cutter generation relative motion, and the conduction of blank rotational power is unaffected.
In this prism working mechanism, described cutter is many, and it is distributed on the outer peripheral face of cutterhead.Usually, the quantity of cutter is two to five.The cutter that is distributed on the cutterhead can improve the process velocity of instrument lathe to prism.
In this prism working mechanism, be respectively equipped with the lining that inside has flower awl groove in described drive bevel gear, the Intermediate bevel gears two, have the spline structure that matches with this flower awl groove with the contacted position of this lining on turning cylinder, the power transmission shaft.
Compared with prior art, beneficial effect of the present invention is:
1, since in the instrument lathe blank on the chuck when processed, can and cutterhead on cutter between relatively rotate, can finish processing so once to prism, process velocity is fast, the machining accuracy height.
2, the power of main shaft rotation is to be provided by gear-driven mode by the turning cylinder that drives the cutterhead rotation, in the manufacture process of instrument lathe reality, can be provided with travelling gear, thereby can determine the relative angle speed of rotating between main shaft and the cutterhead easily, carry out to design the instrument lathe of the different prisms of processing.Instrument lathe in use, the exchange by to the plus-minus or the different size travelling gear of cutter number can make instrument lathe can process different prisms equally, has increased the scope of application of instrument lathe.
