Clamping tool for crystal cutting

Abstract

The invention discloses a clamping tool for crystal cutting. The clamping tool comprises a bottom plate; the bottom plate is connected with a fixing barrel; the fixing barrel is connected with plugboards in the clamping manner; the plugboards are connected with oscillating rods through knuckle bearings; the inner sides of the oscillating rods are hinged to clamping plate devices; electric push rods are arranged on the bottom plate, and are in lifting connection with a backing plate; a pressure-sensitive switch is arranged on the upper side surface of the backing plate; the outer side of the fixing barrel is sleeved and connected with fixing rings; the fixing rings are connected with revolving rings; the outer sides of the revolving rings are sleeved and connected with toothed rings; an upright rod is uniformly arranged on the upper side of each revolving ring; each upright rod is connected with the corresponding oscillating rod; motors are arranged on the bottom plate and are connectedwith gears; and the gears are engaged with the toothed rings. The clamping tool has the advantages that the clamping tool is high in clamping speed, so that a clamped crystal is located in the centerof the fixing barrel and cannot incline; and clamping plates are in soft contact with the crystal and the clamping area is large, so that a previous crystal breaking situation is avoided, and the surface smoothness of the crystal, the center balance of the crystal and the operational stability are ensured.

Description

technical field [0001] The invention relates to the technical field of crystal processing, in particular to a clamping tool for crystal cutting. Background technique [0002] After the crystal growth is completed, it needs to be processed by cutting, polishing and coating. Cutting is the first process of crystal processing. The quality of this process directly affects the subsequent processing. The existing cutting process is generally performed on a cutting machine. When the crystal needs to be clamped before cutting, the tooling used is to set a set of screws on the side wall of an empty cylinder, and the crystal is fastened and fixed by the screws. This method has the following disadvantages: the contact area of ​​the screws is small , in the process of top tightening and locking, it is easy to cause the crystal to break, the number of screws is large, the locking and fixing steps are cumbersome, the balance is poor, the crystal is easy to tilt, and the crystal is not ali...
