Abstract

The invention discloses a mechanical clamping device for a rotary workbench. The device comprises a sliding seat body on the lower part and a workbench on the upper part, and a sliding guide rail surface is positioned between the sliding seat body and the workbench; a piston shaft passes between the sliding seat body and the workbench, the lower part of the piston shaft is connected with a piston, an oily cylinder is matched with the piston, the bottom end face of the piston and the bottom of the oil cylinder form a lower cavity are connected with a hydraulic oil port, and the upper end of the piston shaft is connected with a clamping nut by screw thread; and a disc spring sleeved on the piston shaft is arranged in an upper cavity formed between the upper part of the piston and the upper part of the oil cylinder. By using the mechanical clamping mode of the disc spring, the device has large clamping force, is safe and reliable, and can adjust the amplitude of the clamping force; and the clamping force is directly acted on the sliding guide rail surface, so the device has simple structure and flexible action, does not cause additional deformation of the workbench surface, and can ensure reliable clamping and cannot cause related accidents even if hydraulic faults occur.

Description

technical field

[0001] The invention relates to a mechanical clamping device for a rotary table of a horizontal machining center. Background technique

[0002] The rotary table is the key functional component of the horizontal machining center. It completes the rotary indexing of the workpiece while realizing the linear motion of the machine tool, and realizes the processing of all surfaces of the workpiece in one clamping. During workpiece processing, the rotary table should be reliably positioned and clamped on the worktable, and the rotary table should release the worktable when it is necessary to rotate the index or exchange the worktable.

[0003] At present, the commonly used positioning and locking methods for the rotary table of the horizontal machining center at home and abroad mainly include T-shaped pallet tensioning type, steel ball rod locking type, elastic inclined plane locking type, and lever flat pressing type, etc. The clamping mechanisms of the T-shaped p...
