Problems solved by technology

However, this kind of dead center shaft hob sharpening rod requires repeated disassembly and assembly of the hob to ensure the runout requirements after clamping.
And when the tool bar is worn out, its clamping accuracy is more difficult to guarantee

Embodiment Construction

[0027] The present invention is described in further detail below in conjunction with accompanying drawing:

[0028] see figure 2 , the present invention hydraulically tightens the hob sharpening rod, which changes the original clamping method, the cutter rod 2 is filled with liquid, and the front end is provided with a pressure screw 1, and the liquid is squeezed through the pressure screw 1 to make the cutter rod 2 expand , thereby clamping the hob 3 to ensure that the hob is installed securely. The end of the cutter bar 2 is provided with a pressure adjusting screw 5, when the cutter bar 2 wears and the liquid loss in the cutter bar 2 cannot clamp the hob 3, screw in the adjusting screw 5 to make the internal oil pressure enough to clamp the hob 3. The liquid in the cutter bar 2 is arranged in sections, which can meet the installation requirements of hobs of different lengths and ensure the strength. The present invention is also equipped with adjusting washers of differ...

Abstract

The invention discloses a hydraulic expansion type hob edge grinding cutter rod and a use method thereof. The hydraulic expansion type hob edge grinding cutter rod comprises a cutter rod body and a hob installed on the cutter rod body, wherein the tail end of the hob is clamped by a nut and a gasket; the cutter rod body is filled with liquid; a pressurizing screw is arranged at the front end of the cutter rod body; and the cutter rod body expands by extruding the liquid through the pressurizing screw so as to clamp the hob. The hydraulic expansion type hob edge grinding cutter rod is adopted,so that the tool table run-out requirement during edge grinding can be guaranteed only through one-time clamping, and the problem about installation accuracy caused by abrasion of the cutter rod bodyis avoided. The situation that the run-out value of the parts, at the two ends of the hob, of the tool table is within 0.01 mm can be guaranteed through one-time clamping. About 2800 hobs are subjected to edge grinding totally at present, and the situation that the edge grinding is unqualified does not appear.

Description

technical field [0001] The invention belongs to the technical field of hob sharpening, and relates to a hob sharpening tool, in particular to a hydraulically tightened hob sharpening rod and a use method thereof. Background technique [0002] The hob is an important part of gear processing. The semi-finishing process requires hobbing to remove a large amount of material, which is a heavy cutting tool. Therefore, most gear processing companies use hobs made of special tool materials to improve the processing efficiency of gear hobbing. [0003] The gear hob is a kind of tool for processing gears. The gear hob wears a lot during the process of processing gears. It is often necessary to sharpen the blade of the hob. However, it will cost a lot of money to purchase a special equipment for sharpening the gear hob with a large modulus. More funds, but in general small and medium-sized enterprises adopt outsourcing processing, its disadvantage is that the cost is high, the processi...
