After above-mentioned rubber jacking block 72 damages, chuck can be unloaded, rubber jacking block 72 is ejected through its centre bore from its rear portion.

One drives a transmission device 3, it is to be provided with for the lens 20 that drive chuck 7 and be held rotate together, it is composed as follows: a drive motors 31 is fixedly connected on the supporting plate 13 with the axis of its shaft perpendicular alignmnet chuck 7, with its secured in parallel on supporting plate 13, be a reduction box 33, be in transmission connection between the two be one group of belt drive unit 32.Input gear on reduction box 33 shafts in fixed installation one transfer gear train 34, this gear passes to above-mentioned output gear by an idler gear, makes its rotation power is passed to chuck 7; And

One size control 16, the processing dimension that it aims at accurate control lens 20 is provided with.It comprises that one is fixed in the fixed head 163 of a side of saddle 113, this side is relative with the leading flank of the direction of advance of upper slide rest 44, the tapped through hole that the leading flank of one perpendicular alignmnet upper slide rest 44 is arranged on this fixed head, in this screwed hole, be screwed with an adjustment screw 161, on adjustment screw, be screwed with an adjusting nut 162.According to the requirement of processing dimension, change the front and back position of adjustment screw 161, use adjusting nut 162 that it is locked again, like this, utilize the position-limiting action of 161 pairs of upper slide rests 44 of screw when traverse feed, play the effect of control lens cylinder periphery diameter.

In addition, also have the groove 15 of an admittance finished lens, be contained in lens 20 Working positions under, be fixed on the supporting plate 13.

The operation with this kind processing machine now is described below:

Begin to add man-hour, pull traverse feed handle 43 at first counterclockwise, rotating driver plate 41, thus driving push rod 42, upper slide rest 44 is pulled rearward moving together on saddle 113 in company with supporting plate 13, like this, just make 7 translations of two chucks withdraw from as shown in Figure 1 position.

Then, will be clamped in than the wherein lens blank (glass marble) of homogeneous between the two rubber jacking blocks 72 of end of two chucks 7 through a collection of size just chosen.During desire folder blank, as long as handle 105 is pulled downwards from position as shown in Figure 2, thus the power transmission by pivoted arm pin 109, pivoted arm 107 and finger 106, compression spring 102, drive sliding axle 104 and in axle bed 103, move right, like this, just right side chuck 7 is axially drawn back to the right along it.Pack into behind the blank, release handle 105 under the elastic force of spring 102, makes right side chuck 7 that blank is tightly held out against between left side chuck and himself.Since about two chucks accurately be on the same axis, so blank (glass marble) center is just on the common rotation axis of two chucks.

Then, start grinding wheel drive mitor 8 and drive motors 31, emery wheel 9 rotates, and the motor 31 of rotation drives the left side chuck by above-mentioned a series of transmission devices and blank rotates together.Pull handle 13 more clockwise, make supporting plate 13 drive chucks 7 and blank when emery wheel 9 presses close to treat emery wheel 9 contact blank spheres, slightly with dialling before the handle 43, just ground an endless belt again until blank.Attention: at this moment, the adjustment screw 161 in the above-mentioned size control 16 is adjusted to it is contacted with little supporting plate 44.Then, draw back chuck 7 and blank equally, shut down and to measure the endless belt external diameter that just grinds,, adjustment screw 161 is retreated the spacing of back-outing between corresponding it and the upper slide rest 44, be fixed with adjusting nut 162 again according to the required external diameter of finished lens cylinder periphery.Then, just can utilize handle 43 once again mutually circuitous with pushing away before the blank again with emery wheel 9 until the blank endless belt.After this, two-hand control handle 43 and 111, make blank constantly alternately forward with left and right sides feeding, run into adjustment screw 161 until above-mentioned upper slide rest 44.At this moment, blank has been processed as finished lens.At this moment, available handle 43 draws back finished product 20 backward, shuts down again, pulls handle 105, and finished lens just falls into the groove 15 under it.So far, finished the process operation of lens.

This processing machine shown in the present embodiment, through probationary certificate: the lens accurate to dimension reaches ± 0.05-± 0.10 millimeter, and everyone every monthly output is ten thousand of 3-4, qualification rate 80%, every month about 84 degree of electricity consumption of equipment; Separate unit processing machine volume is about 300 * 400 * 700 millimeters, only about 2000 yuan of equipment investment (not containing processing charges), and the output value can reach every every month about 4000 yuan.At present, just intending promoting the use of.As seen, the utility model processing machine is simple in structure, the loading and unloading barrel is just reliable, process simple and easyly, and finished product accuracy is higher, equipment volume is very little, invests cheaply, really provides a kind of good equipment for processing the reflective cylindrical lens of road.
