Specific embodiment

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear Define.

Refering to attached drawing, a kind of positioning device for eyeglass twin polishing, comprising: planetary gear matrix 1 adjusts ring 2, positioning Ring 3 and locating plate 4.Location hole is provided on planetary gear matrix 1, location hole includes the first side wall and second sidewall, the first side wall Be arranged between second sidewall it is at a certain angle, the angle between the first side wall and second sidewall can be set to obtuse angle or Right angle, positioning ring 3 are arranged between the first side wall and second sidewall.The side wall for namely forming location hole is zigzag, or The inner wall for saying planetary gear matrix 1 is zigzag, and entire planetary gear matrix 1 is to adjust 2 shape sawtooth of ring.It will be in planetary gear matrix 1 Wall is set as zigzag, is used for stationary positioned ring 3, blocks positioning ring 3 by the angle between the first side wall and second sidewall, prevents Only the moving horizontally in positioning hole of positioning ring 3.

The positioning hole that planetary gear matrix 1 is arranged in ring 2 is adjusted, the middle position that ring 2 is placed on positioning hole is adjusted.It adjusts Section ring 2 is set as the thin cyclic structure with opening, i.e. the shape of adjusting ring 2 is similar to " C " shape.The material for adjusting ring 2 is height Carbon steel, the material for such as adjusting ring 2 can select one of spring steel or silicon steel.High-carbon steel has high intensity and hardness, height Elastic limit and fatigue limit, so have opening thin cricoid adjusting ring 2 both can satisfy high intensity, with planetary gear base Body 1 cooperates the fixed function played to positioning ring 3；Also it can satisfy high resiliency, when the size or shape of eyeglass 5 changes When needing replacing the positioning ring 3 of different-diameter, ring 2 is adjusted due to its elastomeric feature and hatch frame, can change and adjust ring 2 The diameter of itself is capable of fixing positioning ring 3 to match with the positioning ring 3 after replacement.

Positioning ring 3 is set as cyclic structure, and eyeglass 5 is exactly to be arranged in positioning ring 3.Positioning ring 3 is arranged in planetary gear base The positioning hole of body 1, positioning ring 3 and the side wall of planetary gear matrix 1 and the outer wall of adjusting ring 2 are inconsistent, pass through planetary gear matrix 1 With the collective effect stationary positioned ring 3 for adjusting ring 2.The side wall being in contact on planetary gear matrix 1 with positioning ring 3 is plane, here Plane be exactly to form the face of sawtooth, between positioning ring 3 and planetary gear matrix 1 for point a face contact, put face contact than existing planet Wheel contacts more firm with the cambered surface of eyeglass 5.

Locating plate 4 is also for positioning eyeglass 5, and eyeglass 5 is exactly to be arranged in locating plate 4, and locating plate 4 is arranged in positioning ring In 3, locating plate 4 and positioning ring 3 are inconsistent.Locating plate 4 is shaped to polygon frame-shaped, according to the different shape of eyeglass 5, The shape of locating plate 4 can be set to one of triangle frame, quadrilateral frame or ladder-shaped frame or a variety of.Positioning ring 3 and positioning Piece 4 is suitable for eyeglass 5 of different shapes, can be passed through by the main positioning round eyeglass 5 of positioning ring 3, oval eyeglass 5 etc. Locating plate 4 mainly positions non-circular eyeglass (eyeglass for having corner angle).Can be and 3 phase of positioning ring by the material selection of locating plate 4 Same material such as all uses Teflon.It, can be in locating plate 4 and positioning ring 3 in order to avoid being damaged to 5 edges and corners of eyeglass Contact position be arranged arc angling, chamfering be arranged on locating plate 4.

Since glass mat toughness is small, brittleness is big, hardness is low, planetary gear in the prior art is using glass mat as material Material is easy to cause the gear teeth of planetary gear that fast, mutability, service life is lost short.The material of planetary gear matrix 1 in the positioning device High-carbon steel can be used, the material of such planetary gear matrix 1 is identical as the material of ring 2 is adjusted, and can be clipped between the two 3 uniform force of positioning ring.

It is put into planetary gear matrix 1 is evenly distributed on the lower mold 6 of Twp-sided polishing machine, is put at 1 center of planetary gear matrix The open loop type of suitable diameter adjusts ring 2, and the selection for adjusting ring 2, which need to meet, is put into positioning between adjusting ring 2 and planetary gear matrix 1 Ring 3 simultaneously can be held in planetary gear matrix 1 out of sawtooth well.Positioning ring 3 is symmetrically caught in and adjusts ring 2 and planetary gear matrix 1 Between, if eyeglass to be processed 5 is non-circular, it is also necessary to be sequentially placed locating plate 4 in positioning ring 3, in positioning ring 3 or determine It is put into eyeglass 5 in bit slice 4, machining lens 5 are normally carried out to end by Twp-sided polishing machine.

It such as needs to process the part of other specifications, need to will only adjust ring 2 and be lifted up, positioning ring 3 is with planetary gear matrix 1 It is separable, change the adjusting ring 2 or positioning ring 3 of other specifications.When loosening, row occurs in the round ring 2 that adjusts that discovery is caught in When the problem of 1 clamping of star-wheel matrix does not live, a kind of larger, elastic better adjusting ring 2 can be replaced.

Since planetary gear matrix 1 is steel body structure, solve the problems, such as that the traditional deformation of planet disk material and intensity are insufficient. Adjusting ring 2 is steel body structure and positioning ring 3 to be located in planetary gear matrix 1 well, can be reduced planetary gear in rotation pair The impact of eyeglass 5, reduces the damage of 5 cylinder of eyeglass, and 5 face type of eyeglass can obtain more accurate control.Planetary gear matrix 1 and adjusting Ring 2 and positioning ring 3 are that single component combination is practical, convenient for the disassembly and replacement of any components, considerably increase operation Convenience and planetary gear utilization rate.

The above is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all utilizations Equivalent structure or equivalent flow shift made by the utility model specification and accompanying drawing content, is applied directly or indirectly in other Relevant technical field, is also included in the patent protection scope of the utility model.
