Simple taper shank puller

Abstract

The invention relates to a simple taper shank puller. A screw is installed on the left part of a support frame, a mixing rod is fixed on the left end of the screw, a pressing plate is fixed on the right end of the screw, the pressing plate is connected with a support plate, a left wedge block is fixed on the support plate by cylindrical pins, and a right wedge block is fixed on the right part of the support frame by cylindrical pins. U-shaped grooves are formed in the left wedge block and the right wedge block, the cross sections of the left wedge block and the right wedge block are inclined surfaces, and the inclination is between 1:4 and 1:5. A drill chuck is arranged in the U-shaped grooves between the left wedge block and the right wedge block. When taper shanks of a milling chuck and the drill chuck are removed, screw transmission is utilized, and extrusion force is generated, so that equipment is difficult to damage. Additionally, different specifications of wedge blocks can be quickly replaced for removal according to different specifications of neck diameters of the taper shanks, so that the efficiency is high. Various specifications and dimensions of U-shaped groove wedge blocks can be processed according to different sizes of the neck diameters of the taper shanks by U-shaped groove holes in the wedge blocks, so as to be convenient to select and use. The wedge blocks of the simple taper shank puller can be manufactured by utilizing leftover materials, the manufacturing is convenient, and the cost is low.

Description

Technical field [0001] The invention relates to a machining tool, in particular to a simple taper shank puller which is driven by a screw and generates extrusion force when disassembling milling chucks, drill chucks and taper shanks, and which is not easy to damage the equipment. Tool. Background technique [0002] In mechanical processing, the collet for installing and disassembling the milling cutter on the milling machine, the collet and the tapping collet for installing and disassembling the tailstock on the lathe, etc., are often tightly assembled and difficult to disassemble when replacing or repairing. At present, there is no special disassembly tool on the market, and the traditional knocking method can only be used for disassembly, which is easy to damage the equipment and has low efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a simple awl that is driven by a scr...
