Description

Extension bar adjusting spinning knife handle

Technical Field

The utility model relates to a handle of a knife centre gripping technical field especially relates to a spinning handle of a knife is adjusted to extension bar.

Background

At present, when a CNC machining center carries out machining on precision machinery parts, a series of machining processes of milling, grinding and cutting are carried out through clamping of the clamping tool holder on the tool, and machining efficiency is high.

Traditional centre gripping can experience the vibrations of longer time at the in-process of lathe machined part, and especially the process time is longer, under the great condition of feed volume, need stabilize the centre gripping to the cutter, prevent that the cutter from becoming flexible. The existing clamping knife handle is complex to install, the clamping of the knife is not easy to adjust, the anti-seismic effect of the clamping of the knife is poor, great coaxiality errors are caused, and the machining precision is low.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model discloses the centre gripping handle of a knife centre gripping cutter installation that will solve is loaded down with trivial details, is difficult for adjusting, the unstable technical problem of centre gripping, the utility model provides an extension bar is adjusted the spinning handle of a knife.

The technical scheme is as follows: the utility model provides an extension bar is adjusted spinning handle of a knife, includes: the handle of a knife main part, install adjusting screw and auto-lock chuck in the handle of a knife main part, the extension bar is installed to the upper end of handle of a knife main part, adjusting screw's lower extreme is connected with the auto-lock chuck.

Preferably, a mounting groove is formed in the tool handle main body, the self-locking chuck is slidably mounted in the mounting groove, and a guide groove matched with the self-locking chuck is formed in the mounting groove.

Preferably, the self-locking chuck comprises a support rod fixed on the adjusting screw, and the lower end of the support rod is connected with a chuck extending out of the tool holder main body.

Preferably, the outer diameter of the collet decreases gradually from the outside to the inside.

Preferably, the clamping head consists of quartered clamping rods.

Preferably, the adjusting screw penetrates through the knife handle main body to be connected with the extension bar.

Preferably, the extension bar is provided with a wrench groove.

Advantageous effects

The utility model has the advantages that the self-locking chuck in the handle body is rotationally pulled backwards by the extension bar under the connection of the adjusting screw, the adjusting screw drives the self-locking chuck to fasten and clamp, the self-locking chuck is firmly installed, the operation is convenient, and the clamping is stable; meanwhile, the extension bar on the tool handle main body is convenient to mount with the main shaft mechanism, the mounting effect is good, the tool handle main body is not easy to damage, and the service life is long.
