Description

Automatic refiner thickness on-line measuring device

Technical Field

The utility model relates to a processingequipment of optical lens piece.

Background

At present, a plurality of optical lens fine grinding devices are not provided with processing and positioning on-line detection devices, and some devices are additionally provided with positioning devices, most of the positioning devices are arranged at the tail parts of arc swing arm shafts to measure the integral size, so that the requirements on the perpendicularity and the assembly precision of a machine table are high; the measurement is not accurate enough and cannot be measured on line; in addition, most refiners are manual and single-sided, which results in poor refining efficiency.

Disclosure of Invention

An object of the utility model is to overcome prior art not enough, provide an automatic refiner thickness on-line measuring device that production efficiency is high, measurement accuracy is high, its application scope is wide.

In order to solve the technical problem, the utility model adopts the following technical scheme:

an automatic refiner thickness on-line measuring device comprises a pressing die, a coupler, a shaft core connector, a shaft core, a displacement sensor, a shaft sleeve, a bearing, a positioning transit cover, an outer sleeve and a spring; the pressing die is connected with the shaft core connector through a coupler; the lower end of the shaft core is arranged on the shaft core connecting head, and the upper end of the shaft core is in contact connection with the displacement sensor; the shaft core is vertically sleeved into the shaft sleeve and can slide up and down along the shaft sleeve; the bearing and the positioning transfer cover are sleeved on the shaft core, and the positioning transfer cover is arranged outside the upper end of the shaft core and then the bottom of the positioning transfer cover is contacted with the outer ring of the bearing; the outer sleeve is covered outside the section of the shaft core above the shaft sleeve, and the lower end of the outer sleeve is connected with the shaft sleeve after the bearing and the positioning transit cover are covered; the upper end of the outer sleeve is provided with a through hole for the displacement sensor to penetrate into contact with the positioning middle rotating cover.

Compared with the prior art, the beneficial effects of the utility model are that: because lean on the back on the lens with the moulding-die top, along with the grinding of lens makes displacement sensor carry out on-line measuring, to the straightness that hangs down of correct grinding board and assembly accuracy requirement not so high like this to simplified on-line measuring device's installation and location greatly, consequently the utility model discloses a structure is more reasonable, and it can more accurate measurement lens thickness through on-line measuring.

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

Fig. 2 is a schematic structural diagram of an embodiment of the present invention;

Fig. 3 is a schematic diagram of a displacement sensor of a conventional type.

[ detailed description ] embodiments

The utility model relates to an automatic refiner thickness on-line measuring device, as shown in figures 1 and 2, comprising a pressing die 1, a coupling 2, a shaft core connector 3, a shaft core 4, a displacement sensor 5, a shaft sleeve 6, a bearing 7, a positioning transit cover 8, an outer sleeve 9 and a spring 10; the pressing die 1 is connected with the shaft core connector 3 through a coupler 2; the lower end of the shaft core 4 is arranged on the shaft core connector 3, and the upper end of the shaft core is in contact connection with the displacement sensor 5; the shaft core 4 is vertically sleeved in the shaft sleeve 6 and can slide up and down along the shaft sleeve 6. As shown in fig. 2, the bearing 7 and the positioning transit cover 8 are sleeved on the shaft core 4, and the positioning transit cover 8 covers the upper end of the shaft core 4 and then the bottom of the positioning transit cover 8 is in contact with the outer ring of the bearing 7, so that when the shaft core 4 rotates with the pressing die 1, the positioning transit cover 8 cannot rotate, and the displacement sensor 5 in contact with the positioning transit cover 8 cannot cause inaccurate measurement due to rotation abrasion, thereby ensuring the measurement accuracy of the displacement sensor. The outer sleeve 9 is housed in the section of the shaft core 4 above the shaft sleeve 6 and covers the bearing 7 and the positioning turning cap 8 and then is connected to the shaft sleeve 6 at its lower end (typically screwed together), which reduces the effect of ambient dirt on bearing performance and life. The upper end of the outer sleeve 9 is provided with a through hole 91 for the displacement sensor to penetrate into and contact with the positioning transit cover 8.

The utility model discloses when using, fix to the refiner through 6 installations of its axle sleeve to make its moulding-die 1 lower extreme support on treating the lens of correct grinding, can set for displacement sensor's measurement starting point this moment. Next, the refiner work, make its bistrique begin to grind the lens, then along with the grinding of bistrique to the lens, moulding-die 1 can follow and move down, under spring 10's effect, shaft coupling 2, axle core connector 3, axle core 4, bearing 7 and location transfer lid 8 can descend simultaneously, because 5 lower extremes of displacement sensor support to lean on in the location on the transfer lid 8, then displacement sensor 5 also follows synchronous the lapse, thereby make the sensor carry out on-line measurement to the lens in the grinding, just so can carry out accurate measurement to the lens grinding. From the above, thickness on-line measuring device leans on its moulding-die top back on the lens, and along with the grinding of lens makes displacement sensor carry out on-line measuring, and the straightness that hangs down to the correct grinding board like this and assembly precision require not so high to on-line measuring device's installation and location have been simplified greatly, consequently the utility model discloses a structure is more reasonable, and it can more accurate measurement lens thickness through on-line measuring.

At this stage, the displacement sensor 5 is a relatively mature product, as shown in fig. 3, and will not be described in detail.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the present disclosure, but rather to limit the scope thereof by the appended claims.
