Description
The utility model relates to a kind of mechanical centering edge polisher of processing lens.
In the manufacturing of optical lens, critical process is arranged one, exactly to lens feel relieved edging and chamfering, the former in order to guarantee lens in use its optical centre overlap with geometric center, the latter is in order to the design needs that satisfy lens and the protection of lens.Existing mechanical lens centering-edging machine is made up of lathe bed, main spindle box, grinding carriage and transmission system, wherein main spindle box is again by casing, left and right main shaft, power transmission shaft and range controlling mechanism constitute, the trip controlling organization links to each other with the main spindle box casing, it only adopts a spring, a push rod, and a micrometer and monolateral locating piece make push rod contact with cam in the transmission system all the time by the spring action push rod.When the rotation of transmission system drives cam, cam drives main spindle box by range controlling mechanism and moves, and guarantees that the lens that will process between the left and right main shaft are in correct position, is convenient to chamfer angle edging.But this range controlling mechanism can only folk prescription to the control stroke, because cam is the rigidity contact with contacting of push rod, push rod is connected for whole with the main spindle box casing, then the main spindle box casing must could return under the effect at spring when cam is gone to range point, and by locating piece main spindle box is stopped on the position of being set by micrometer in this backstroke.The stroke adjustment troublesome poeration that this just makes lens processing, production efficiency is low.And, then make positioning accuracy lower because cam has participated in positioning control as driving member.
The purpose of this utility model is exactly to provide a kind of positioning action easy in order to address the above problem, positioning accuracy is high can two-way accurate location the mechanical centering edge polisher.
Technical solution of the present utility model:
A kind of mechanical centering edge polisher that can two-way accurate location, it includes lathe bed (1), main spindle box (2), grinding carriage (3) and transmission system (4), wherein main spindle box (2) is by left and right main shaft (5), (6), power transmission shaft (7) and casing (8) constitute, main spindle box casing (8) bottom is connected with locating piece (9), it is characterized in that front and back two side positions that should locating piece (9) respectively are provided with one and regulate micrometer (22), (23) on another fixture; Be fixed with a push rod bearing (10) and a spring adjusting bearing (11) in main spindle box casing (8) bottom, push rod bearing (10) is passed in push rod (12) front portion, its front end contacts with cam (13) in the transmission system (4), be with first spring (14) on push rod (12) the back step axle, on the end face forward of spring adjusting bearing (11), have endoporus (15), be provided with the adjusting jacking block (16) that is slidingly fitted in the endoporus (15), the front end face of this adjusting jacking block (16) just is against the rear end of first spring (14), on the end face backward of spring adjusting bearing (11), have screw (17) concentric with its endoporus (15) and that communicate, this screw (17) adjustment screw (18) that has been threaded, adjustment screw (18) front end is against to be regulated on the jacking block (16), the front portion of second spring (19) is sleeved on the rear portion screw rod of adjustment screw (18), its rear portion is sleeved on the guiding screw pole (20) that is fixed on another fixture simultaneously, and the adjusting nut (21) that the rear end of second spring (19) is directed on the double-screw bolt (20) props up.
But the utility model adopts the structure of relative motion to be connected main spindle box casing and push rod first, makes the output cam of transmission system only move as driving member, and does not participate in positioning control, and this just makes machining accuracy improve greatly.Simultaneously, the utility model has adopted two micrometers and dual spring governor motion again, then can make moving in stroke range of main spindle box casing, regardless of being reach or returning all and can locate arbitrarily that positioning action is greatly simplified, and production efficiency improves greatly.
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the utility model main spindle box structure and range controlling mechanism enlarged diagram thereof;
Fig. 3 is the generalized section of Fig. 2.
The course of work of the present utility model such as Fig. 1-3, the pretightning force that elder generation regulates first spring (14) and second spring (19) respectively by adjustment screw (18) and adjusting nut (21), owing to make the pretightning force of the pretightning force of first spring (14) after the rigidity of first spring (14) greater than the rigidity of second spring (19), is then regulated greater than second spring (19).The utility model realizes that by the difference of first and second spring (14), (19) pretightning force the location of main spindle box (2) moves control exactly.When transmission system (4) drives its output cam (13) rotation, because of the pretightning force of first and second spring (14), (19) is far longer than rail friction power, then first spring (14) can be considered as rigidity, cam (13) is by push rod (12) and first spring (14) and then compress second spring (19), when cam (13) when not covering range, the locating piece (9) of main spindle box casing (8) bottom is run into location, back micrometer (23), then casing (8) stops to move, and cam (13) is rotated further.At this moment compress the range that first spring (14) release cam (13) is not covered.When cam (13) is backed to square one by the range place, because the effect of second spring (19), make main spindle box casing (8) return forward, when its locating piece (9) is run into prelocalization micrometer (22), casing (8) stops again, and cam (13) is rotated further, and this moment, push rod (12) upper bearing (metal) did not contact with cam surface, cam (13) is got back to start position, and a course of work finishes.So move in circles and just can arbitrarily regulate any shift position of main spindle box (2) easily, be convenient to lens feel relieved edging and chamfering.
