Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
Embodiment one
As shown in Figure 1, Figure 3, the optical glass grinding bistrique cutter feeding control device of the present invention, including the motor 2 for rotating with rotary bistrique with for installing the sliding sleeve 1 of motor 2, motor 2 can slide up and down freely in sliding sleeve 1, sliding sleeve 1 is fixing with milling drum support 10 to be connected, and the lower output side of motor 2 is connected with bistrique 4 by connecting rod 3.During optical glass grinding, the pressure of bistrique 4 is generally less, and especially in lapping process, the gravity of motor 2 is generally higher than the pressure needed for bistrique 4 grinding, when pressure is excessive, is easily caused the broken of eyeglass, and the eyeglass that thickness is less, material is more crisp is especially true.Therefore, the present invention adopts the accurate controlling organization arranging lifting type in the bottom of motor 2 to decline the pressure of feed and speed controlling bistrique 4.Cam 5 and cam drive mechanism that described accurate controlling organization can be touched by the bottom end face with motor 2 form, and cam 5 and cam drive mechanism can pass through support 9 and be connected with sliding sleeve 1 and support 10.Its cam actuation includes the travelling gear 8 coaxially connected with described cam 5 and tooth bar 7, one end of tooth bar 7 is arranged to the reciprocating extending cylinder 12 of band carry-over bar 7, tooth bar 7 engages with travelling gear 8, and the reciprocating motion of tooth bar 7 is thus converted to the positive and negative rotation motion of travelling gear 8 and cam 5 under the drive of extending cylinder 12.
The bistrique cutter feeding control device of the present invention controls the speed of cam 5 positive and negative rotation by the Stress control transmission of extending cylinder 12, and control motor 2 and the rising or falling speed of bistrique 4 with this, also allow for grinding feed velocity simultaneously and grinding force is controlled effectively, grinding accuracy error can be controlled in ± 0.01mm within, and effectively prevent hypertonia and cause eyeglass to be damaged or feed velocity is low and phenomenon that cause grinding efficiency is relatively low.
Embodiment two
Referring to Fig. 2, present embodiment is as the further improvement on embodiment one technical scheme basis, one support roller 11 can be set between described cam 5 and motor 2 bottom face, to reduce the frictional resistance between cam 5 and motor 2 bottom face, reduce the abrasion of cam 5 and motor 2 bottom face simultaneously, extend its service life.Certainly, supporting roller 11 can adopt bearing or other structure to be connected with motor 2.
Embodiment three
As shown in Figure 4, as the embodiment improved further, extending cylinder 12 can adopt speed-adjustable fluid cylinder.Speed-adjustable fluid cylinder includes piston 12-4, piston rod 12-3, liquid storage cylinder 12-2 and is positioned at the working cylinder 12-1 of oil storage cylinder 12-2.Working cylinder 12-1 is the barrel-like structure of one end open, and the gap between the end cap 12-5 of its opening and oil storage cylinder 12-2 constitutes fluid circulation passage.Closing one end of working cylinder 12-1 is connected to adjusting screw rod 12-6, it is connected to support 12-7 outside the end cap 12-5 of one end that oil storage cylinder 12-2 is corresponding, adjusting screw rod 12-6 and oil storage cylinder 12-2 and support 12-7 installs and is connected, adjusting screw rod 12-6 arranges left and right adjusting nut 12-9,12-8, left and right adjusting nut 12-9,12-8 lay respectively at the both sides of support 12-7, can be realized the adjustment of described fluid circulation passage size by turn left and right adjusting nut 12-9,12-8.Working cylinder 12-1 connects with high-pressure pipeline 12-10,12-11 respectively with oil storage cylinder 12-2, is respectively used to working cylinder 12-1 and oil storage cylinder 12-2 and passes in and out the circulation of fluid.This extending cylinder 12 is when working cylinder 12-1 is by high-pressure pipeline 12-10 oil-feed, promote piston 12-4 and drive piston rod 12-3 and described tooth bar 7 to be moved to the left, fluid on the left of piston 12-4 enters liquid storage cylinder 12-2 by described fluid circulation passage, and flows out through high-pressure pipeline 12-11；When high-voltage oil liquid is entered in liquid storage cylinder 12-2 by high-pressure pipeline 12-11, the hydraulic oil in liquid storage cylinder 12-2 also enters working cylinder 12-1 through described fluid circulation passage, and promotes piston 12-4 and drive piston rod 12-3 and described tooth bar 7 to move right.When carrying out grinding, the size of described fluid circulation passage is adjusted by turn left and right adjusting nut 12-9,12-8, also it is achieved that the adjustment of the fluid uninterrupted of turnover working cylinder 12-1, and determines piston 12-4 translational speed and the size of bistrique 4 rising or falling speed.
Embodiment four
Referring to Fig. 4, as further improvement, present embodiment working cylinder week side short tube 12-12 of at least one connection working cylinder 12-1 and oil storage cylinder 12-2 is set, this short tube 12-12 arranges check valve 12-13.Thus structure can realize the moving to left at a slow speed of piston 12-4, quickly move to right, that is realizes feed at a slow speed and the fast lifting of bistrique 4, improves the efficiency of eyeglass grinding operation further.
Embodiment five
In conjunction with Fig. 3 referring to Fig. 5, arranging at cam 5 excircle and high-order wait segmental arc A, rapid feed segmental arc B and grinding feed segmental arc C, central angle corresponding to three segmental arcs can be respectively set to: high-order waits segmental arc A60 °, rapid feed segmental arc B60 ° and grinding feed segmental arc C240 °.Wherein, high-order wait segmental arc A is isometrical arc structure, and when this segmental arc contacts with motor 2 bottom face or roller 11, it is slack that bistrique 4 is suspended in extreme higher position, and this period is upper with the feed of eyeglass to be ground for taking off of grinding eyeglass of completing；Rapid feed segmental arc B has less curvature, and when bistrique 4 is not close to eyeglass to be ground, rapid feed segmental arc B contacts with motor 2 bottom face or roller 11, and bistrique 4 declines with speed faster, it is possible to save the feed time, improves grinding working performance；Grinding feed segmental arc C is the involute shape that curvature is bigger, when bistrique 4 is close to eyeglass to be ground, grinding feed segmental arc C contacts with motor 2 bottom face or roller 11, and bistrique 4 declines with grinding speed slowly, grinding accuracy can be controlled preferably, it is prevented that crushing of eyeglass.
Although above, presently preferred embodiments of the present invention is shown and described, so that principles and applications to be described, it is to be understood that the present invention otherwise can realize on the basis not necessarily depart from these principles.
