Example Embodiment

[0027] by Figure 1-Figure 7 The special fixture for grinding of HSK tool holder series tools shown includes a flange shaft connected to the main shaft of the machine tool and an HSK adjustment mechanism. The HSK adjustment mechanism includes a convex block arranged horizontally, and the convex block has a cavity along the central axis 13 The cavity 13 is a through hole in the convex block. The convex block is divided into a protrusion 4 on the left and a bottom block 6 on the right. The part of the cavity 13 facing the right end of the bottom block 6 is The taper of the HSK tool holder is adapted to form a taper surface 12, and the HSK tool holder is connected to the HSK tool 17 in order to match the taper surface 12 with the HSK tool holder in the future. The bottom block 6 is provided with an axial adjustment screw hole; the flange shaft includes a flange plate 2 and a connecting shaft 1 fixed horizontally on the left side of the flange plate 2. The connecting shaft 1 is a h...

Abstract

The invention discloses a fixture special for grinding and machining of an HSK (Hohl Schaft Kegel) shank series cutter. The fixture comprises a flange connected with a machine tool spindle, and an HSK adjusting mechanism, wherein the HSK adjusting mechanism comprises a convex block, the convex block is provided with cavities along a central axis; the cavity on the left side of the convex block isprovided with an HSK broach claw, and the cavity facing the right end surface of a bottom block is in a taper shape adaptive to an HSK shank; the flange comprises a flange plate and a connecting shaft horizontally and fixedly arranged on the left side of the flange plate, the right end surface of the flange plate is provided with a concave cavity, and the convex part of the convex block is positioned in the concave cavity; the left end surface of the bottom block is opposite to the right end surface of the flange; the flange plate at the circumference of the convex part is provided with a radial adjusting top thread, and the bottom end of the radial adjusting top thread leans against the external surface of the convex part; and the bottom block of the convex block is provided with an axial adjusting top thread, and the bottom end of the axial adjusting top thread leans against the right end surface of the flange. The fixture can effectively increase the combined rigidity of the shank to the machine tool spindle, greatly increase the repeated positioning accuracy and has a good high-speed locking property.

Description

technical field [0001] The patent of the present invention belongs to the technical field of mechanical processing, and in particular relates to a special fixture for grinding processing of HSK tool handle series tools. Background technique [0002] High-speed cutting has become an important part of machining and manufacturing technology. The positioning accuracy and connection stiffness of the tool holder are two important indicators to measure the tool system. In the grinding process, the accuracy of the positioning accuracy of the tool holder and the improvement of the connection stiffness It is the guarantee of the overall machining accuracy of the tool. The structure of the HSK tool holder taper is different from the commonly used BT tool holder. It is a new type of high-speed tapered tool holder. It adopts the dual positioning method of the cone surface and the end surface. Under the action of a large enough tension, HSK 1: The friction between the 10 hollow tool tape...
