Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a deep hole drilling machine clamp. Background Art

[0002] Deep hole drilling machines are different from traditional hole processing methods. They mainly rely on specific drilling technologies (such as gun drilling, BTA drilling, ejector drilling, etc.). Special machine tools for drilling deep hole systems and precision shallow holes with an aspect ratio greater than 10 are collectively referred to as deep hole drilling machines.

[0003] For example, a Chinese utility model patent (CN208913617U) discloses a steel clamp for a deep hole drilling machine. When the clamp clamps workpieces of different weights, the stability of the clamp is improved. However, the above-mentioned clamp does not have the function of flipping. When drilling is required on the reverse side of the clamped workpiece, it is necessary to first release the clamp of the workpiece, flip the workpiece and then re-clamp it before processing can be performed. The operation is cumbersome. For this reason, the present application proposes a deep hole drilling machine clamp. Utility Model Content
