Background

The traditional optical polishing process usually uses a single-shaft separator process, as shown in fig. 1, that is, the processed surface of a workpiece is punched down, and grinding and polishing are realized on a lower disc of a single-shaft machine. The single-shaft machine swing arm is connected with the center of the four-claw tool, and the crank rocker structure of the single-shaft machine drives the swing arm to swing, so that the tool assembly is driven to swing on the lower disc of the single-shaft machine, the lower disc of the single-shaft machine rotates, and the workpiece rotates along with the workpiece ring, the separator and the like under the action of friction force. However, this method is only suitable for processing small optical elements, because the swing arm center drives the tooling assembly, the four-claw tooling has large rigidity difference, the four claws are not beneficial to placing and taking down the workpiece above the separator, generally, the four claws need to be disassembled first, and then the workpiece can be conveniently placed and taken down, which is very inconvenient.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the present invention provides a grinding and polishing machine tool for large flat thin plate elements, including a spindle system and a separator system, where the separator system includes two guide rail seats oppositely disposed on two sides of the spindle system, the two guide rail seats are connected by a sliding frame erected above the spindle system, the sliding frame includes a driving wheel and at least one driven wheel, the driving wheel and the driven wheel are engaged with a driving ring on a lower disc of the spindle system, and a separator web is mounted and fixed at a lower end of the driving ring.

As a preferred embodiment, the sliding frame includes two movable plankers mounted on the guide rails of the guide rail bases, and the movable plankers on each guide rail base are connected through two cross beams.

In order to effectively slide the frame, translation motors are respectively arranged at the same ends of the two guide rail seats, and each translation motor is connected with a movable carriage on the respective guide rail seat through a screw rod or a gear rack structure.

In order to make the driving ring rotate effectively, the number of the driven wheels is 3, and the driven wheels and the driving wheel are arranged on the beam in a pairwise symmetry mode.

The utility model discloses advantage lies in, has solved the problem that traditional single-axis machine can not process the heavy-calibre work piece, and the work piece top does not block simultaneously, is convenient for adopt frock such as vacuum chuck make things convenient for putting and lift off of work piece.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive labor.

FIG. 1 is a schematic top view of a single-spindle machining state of the prior art.

Fig. 2 is a schematic structural diagram of a grinding and polishing machine for large-sized planar thin-plate elements according to an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model provides a grinding and polishing lathe of large-scale plane sheet metal component, as shown in fig. 2, main shaft system 1 is used for bearing the weight of the work piece and drives its lower wall rotation through servo motor. The specific structure is the prior art and is not described herein. Guide rail seats 2 and 3 are arranged on two sides of the main shaft system 1 and are arranged in parallel relatively. Each rail seat is provided with a rail 21 and 31. The guide rails 21 and 31 are respectively provided with movable plankers 22 and 32. In this embodiment, the same end of the rail bases 2 and 3 is provided with a translation motor 23 and 33, and each translation motor is connected with the movable plankers 22 and 23 on the corresponding rail base through a screw rod 24 and a screw rod 34. So that the movable carriages 22 and 23 can slide on the guide rails 21 and 31 under the driving of the translation motors 23 and 33. It should be noted that the screw rod connection mode provided by the embodiment of the present invention is a preferable example, and it cannot limit and restrict the protection scope of the present invention. The technical personnel in the field can also select a gear and rack structure to connect the motor and the movable carriage, so other similar technical schemes such as the gear and rack structure are adopted and still in the protection scope of the utility model.

The two ends of the movable plankers 22 and 23 are connected through

cross beams

41 and 42. Such that the

beams

41 and 42 are parallel and at a distance. In this embodiment, a drive wheel 51 is mounted on the inner side of the cross member 42, and the drive wheel 51 is driven to rotate by a workpiece ring motor 52 at the upper end. A driven wheel 61 is also mounted on the inside of the cross beam 42 on the side close to the rail housing 3. While the driven

wheels

62 and 63 are fixed at positions corresponding to the driving wheel 51 and the driven wheel 61 inside the cross beam 41. The drive pulley 51 and the driven

pulleys

61, 62, 63 are engaged with the drive ring 11 on the lower disc of the spindle system 1. The drive pulley 51 thus rotates the drive ring 11 on the spindle system 1 under the drive of the workpiece ring motor 52 and the cooperation of the three driven pulleys. The outer ring of the driving ring 11 is provided with teeth, the lower end of the driving ring is fixed with a separator web 12 with the inner diameter, and the middle of the web 12 is provided with a hole corresponding to the size of a workpiece. The workpiece is machined by simply placing the workpiece in the hole in the web 12.

The separator system in this example embodiment is composed of the above-described structure, which is completely different from the separator system of the existing single-shaft machine. When in use, a workpiece can be processed only by being put into the hole of the separator web 12. When in processing, the workpiece is limited, so that the follow-up planker can realize front and back displacement and can also rotate along with the driving ring 11. The structure is convenient for placing and unloading the workpiece, and can realize the processing of large-size workpieces.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
