Description

A kind of optical device balladeur train

Technical field

The utility model relates to balladeur train, is specifically related to a kind of optical device balladeur train.

Background technology

The raising of optical element suface processing quality, require repeatability and the regularity of stylus movement locus in photo process equipment, this is mainly by the flexibility of balladeur train mid portion motion, and the key of kinematic dexterity, be coordinate the linear bearing slided to determine by two slide bars and it.Over nearly 20 years, LM30UU type linear bearing continued to use by the bearing in carriage components always, and linear bearing LM30UU is the Common parts of outsourcing, and slide bar is self-made components, and slide bar hardness is 48HRC-52HRC, the whole body Quenching Treatment.Add man-hour, the material of workpiece (optical glass), diameter and stylus pressure are in different size, cause slide bar stressing conditions different, the length of equipment available machine time every day, with the factor such as the maintenance of balladeur train, all can cause the heavy wear of parts.After wearing and tearing, the fit clearance of slide bar and bearing can sharply become large, and cause actuating station stylus to operate not in place, unstable, the precision of the optical element of processing reduces greatly, and percent defective raises.

Show through using, short 1 year of time, 2 years-3 years long carriage components just there will be heavy wear, carriage components wearing-in period is short, keeps in repair time-consuming, delays production, increase production cost, up to the present, the change that this more serious abrasion condition is never large, essential.

Summary of the invention

Technical problem to be solved in the utility model is a kind of optical device balladeur train of design, and the problem of the carriage components serious wear of this optical device balladeur train is solved at all.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of optical device balladeur train, comprise balance staff eccentric structure, stylus structure, cylinder-pressing structure, balladeur train rotational structure, balladeur train slide construction, described balance staff eccentric drive balladeur train rotational structure, the bearing under balladeur train slide construction drives the translation of balladeur train slide construction, balladeur train rotational structure drives the action of stylus structure by slide bar, bearing, and cylinder-pressing structure provides operating pressure for stylus structure; Described bearing is Throw bearing.

Described bearing is ST30UU Throw bearing.

Described slide bar is the slide bar after the surface hardening that 1.5mm-2.5mm is dark, and slide bar hardness is 60HRC-64HRC.

The utility model adopts a kind of optical device balladeur train designed by technique scheme, owing to changing bearing into Throw bearing ST30UU by linear bearing LM30UU, slide bar is quenched from original the whole body and becomes the dark surface hardening of 1.5mm-2.5mm, and hardness brings up to 60HRC-64HRC by original 48HRC-52HRC.Bearing is when using grease lubrication, and first remove anti-corrosive oil by kerosene or organic molten Ji, add lubricating grease again after air-dry, the longer service life of balladeur train, wear and tear less, result of use is obvious.The utility model may be used for the production of existing new equipment and the transformation of a large amount of used equipment, and can carry out large-area popularization in optics industry, to improve the serviceability of optical device, and produces better economic benefit.

Accompanying drawing explanation

Fig. 1 represents the structural representation of the utility model kind optical device balladeur train.

Detailed description of the invention

Illustrate below in conjunction with the structure of accompanying drawing to a kind of optical device balladeur train of the utility model.

See Fig. 1, a kind of optical device balladeur train of the utility model, comprises balance staff eccentric structure 3, stylus structure 2, cylinder-pressing structure 6, balladeur train rotational structure 5, balladeur train slide construction 4.Its eccentric size adjustable (0mm-26mm) of balance staff eccentric structure 3, balance staff eccentric structure 3 drives balladeur train rotational structure as the power intake of sledge movements, balladeur train slide construction transmits eccentric disc rotary motion (movement), is also the basic part of overall balladeur train, plays a supportive role.The bearing 1 of balladeur train slide construction 4 bottom drives balladeur train slide construction 4 translation.Balladeur train slide construction 4 transmits eccentric disc rotary motion-movement, meanwhile, is also the basic part of overall balladeur train, plays a supportive role.Bearing 1 changes Throw bearing ST30UU into by linear bearing LM30UU, slide bar is quenched from original the whole body and becomes the dark surface hardening of 1.5mm-2.5mm, hardness brings up to 60HRC-64HRC by original 48HRC-52HRC, so neither affect slide bar intensity, the hardness on its surface can be increased again, reach the effect improving its wearability.Bearing 1, when using grease lubrication, is first removed anti-corrosive oil by kerosene or organic molten Ji, is added lubricating grease again after air-dry.Balladeur train rotational structure transmits the rotary motion (rotation) of eccentric disc, and drive stylus structure 2 action by slide bar, bearing 1, stylus structure 2 is the final actuating station of the utility model processing work.Cylinder-pressing structure 6 provides operating pressure for stylus structure.

The load that Throw bearing of the present utility model bears is about 2.67 times-3.56 times of linear bearing bearing load, and the dynamic and static load of Throw bearing is 4120N, 9310N respectively, and the dynamic and static load of linear bearing is 1560N, 2740N respectively.By the numerical computations of Dynamic And Static Loads, light load Throw bearing, the load of bearing, is about 2.6,3.4 times that the linear bearing of equal model bears dynamic and static load, if be changed to middle load Throw bearing type, the load of bearing, can increases by 2 times again.

The motion of the utility model carriage components, drives eccentric disc to move in a circle by the balance staff of balance staff eccentric structure 3, then drives sledge movements (resultant motion of balladeur train rotation and movement), finally, drives the stylus of stylus structure to rotate.Stylus movement locus is irregular closed curve, and this curve is made up of two sections of circular arcs, symmetrical, left-right asymmetry up and down, also can be simply referred to as class elliptical orbit.The raising of optical effect correction surface quality, require repeatability and the regularity of stylus movement locus, this is mainly by the flexibility of balladeur train mid portion motion, and the key of this kinematic dexterity, be coordinate the Throw bearing slided to complete by the utility model two slide bars and it.

The utility model is on probation through trial-production, drops into technological transformation equipment 6 altogether, fine grinding, each 3 of polissoir, and the every platform 4 of refiner overlaps balladeur train, and the every platform 8 of polishing machine overlaps balladeur train, and amounting to experiment quantity is 32 cover sliding units.According to the time of setting in advance, detecting, 2 years-3 years service time, not having wear phenomenon to often overlapping sliding unit, after 4 years-5 years, the vestige yet do not worn and not torn, when using 6 years-7 years, does not still find that slide bar has wearing and tearing.As can be seen here, the sliding framework structure after this improvement can solve the heavy wear problem of carriage components.Infer from actual tests situation analysis, in the service life of sliding unit, conservative estimation can reach 10 years-12 years, is more than 5 times of original structure service life.
