A balanced loading device for a sapphire double-sided grinding machine

Abstract

A balance type disk feeding device for a double-side grinding machine of sapphire is installed above a disk feeding system (10) of the grinding machining, and is installed on a center spline shaft (6) in a sleeving manner, and comprises an upper connecting plate (4), a lower connecting plate (7) and a gear (11), wherein the spline shaft is sleeved with the upper connecting plate (4), the lower connecting plate (7) and the gear (11) in sequence from top to bottom. A cylinder (3) and a balance weight oil pressure cylinder (2) are symmetrically installed on the two sides of the lower end of the lower connecting plate; ejecting rods of the cylinder and the balance weight oil pressure cylinder are fastened and connected into screw holes in the two sides of the upper connecting plate correspondingly; the rear side of the lower connecting plate is fixedly connected to a gantry stand column cross beam; a planet wheel speed reducer (5) with an output shaft extending downwards and penetrating the cross beam is installed on the cross beam; a planet wheel speed reducer gear at the lower end of the output shaft is engaged with the gear (11) arranged on the lower portion of the spline shaft in a sleeving manner; and a horizontal adjusting base assembly (9) is arranged at the bottom of a closing cover (8) covering the exteriors of the planet wheel speed reducer gear and the gear. The balance type disk feeding device for the double-side grinding machine of the sapphire is simple in structure, easy to control, good in balance effect, reliable in performance and high in precision.

Description

technical field [0001] The invention relates to the technical field of the upper disc system of a double-sided grinder. Background technique [0002] In the existing sapphire double-sided grinding machine, the gravity balance of the upper plate is a technical problem in the high-precision grinding process. Due to the influence of gravity, the control system needs to compensate the gravity of the upper plate pressure during the processing process due to the influence of gravity, which increases the double-sided Grinding control is difficult, resulting in adverse effects on product quality. There are roughly two existing solutions: one is to correct the pressure of the upper plate through the control system during grinding, so as to ensure that the grinding pressure meets the grinding requirements of the product. The second is to add weights and counterweights outside the loading system to balance the gravity of the loading system. In the above methods, when the grinding pre...

Problems solved by technology

In the above methods, when the grinding pressure is lower than that of the upper disk system, or the gravity and direction of the upper disk system change, the difficulty of balance adjustment will increase accordingly, thus affecting the grinding accuracy.
