Four-axis multi-functional numerical control broach grinding machine

Abstract

The invention discloses a four-axis multi-functional numerical control broach grinding machine which comprises a numerical control cross-shaped sliding table. A heightening pad is arranged on one side of the numerical control cross-shaped sliding table, a headstock and a tailstock are installed at the two ends of the heightening pad respectively, a plurality of center frames are arranged on the heightening pad and located between the headstock and the tailstock, and a grinding wheel dresser is installed on one side of the heightening pad. A numerical control stand column sliding table is arranged on the side, where the heightening pad is located, of the numerical control cross-shaped sliding table, a B-axis rotation device is installed on the table top of the numerical control stand column sliding table, a C-axis rotation device is installed on the B-axis rotation device, a grinding wheel frame is arranged below the C-axis rotation device, and a grinding wheel is further installed. By means of the four-axis multi-functional numerical control broach grinding machine, the machining requirements of various broaches can be met, and the investment of equipment is reduced.

Description

Technical field[0001]The present invention belongs to the field of CNC pull tool grinding machines, and more particularly to a four-axis multifunctional CNC pull tool grinder.Background technique[0002]Ordinary pull knife grinding is based on the operator's experience, according to the sparks of grinding to control the grinding amount; ie the multi-function CNC pull the knife machine, in the grinding, it is also based on the requirements of the drawings, one tooth one tooth The knife grinding, the grinding time is long, low production efficiency; at the same time, it is not possible to adjust the teeth according to the processing of the front process, so that the cutter of the grinding is different, the knife teeth thickness is different. The life of the drawn knife. And, after grinding, the machine has no memory function, secondary grinding, still needs to start from starting manual pairs.[0003]At present, the existing pulley grinding machine is a two-coordinate machining transmissi...

AI Technical Summary

Problems solved by technology

[0005] 1. This technology can only be used for one type of broach grinding, such as grinding one of cylindrical broaches, spline broaches, flat broaches, spiral broaches, etc.

[0006] 2. It is not possible to measure the previous process of the broach before grinding, and it can only be processed according to the given program, which cannot achieve parametric processing

[0007] 3. The tailstock of this technology cannot adapt to the influence of various broaches due to their own weight, and the height of the top of the tailstock cannot be adjusted according to the weight of the broach
