Description
Technical Field
The invention relates to the field of cutter machining, in particular to a symmetrical double-spindle cutter groove grinding machine.
Background
In the current rotary hard alloy cutter production and manufacturing process, the groove grinding time of the cutter occupies about 50% of the whole cutter production and manufacturing time or even more. The existing cutter grinder comprises a single main shaft adopted by a special cutter groove grinding machine tool, and each groove of the cutter needs to be ground one by one, so that the efficiency is low, and when the slender cutter is ground, the rigidity and clamping rigidity of a cutter bar are weak, and when the groove is ground, the feeding speed is reduced, so that the stress deformation and vibration of the bar are reduced when the groove is ground. The efficiency of the groove grinding of the elongated tool is lower.
Disclosure of Invention
In order to solve the existing problems, the invention provides a symmetrical double-spindle cutter groove grinding machine.
The utility model provides a symmetry double spindle cutter groove grinder, includes work piece axle stand, grinding spindle stand and locates the grinding machine seat of work piece axle and grinding spindle stand bottom, fixedly connected with work piece axle on the work piece axle stand, work piece axle stand below fixedly connected with work piece axle workstation, the grinding spindle stand respectively establishes one and mutually opposites in work piece axle stand the place ahead left and right sides, be equipped with the altitude mixture control spout in the vertical direction of grinding spindle stand, be equipped with the swinging groove on the altitude mixture control spout, be connected with the grinding spindle in the swinging groove, be equipped with two fluting emery wheels on the grinding spindle.
By way of further illustration, a triangular structure is formed between the workpiece axle stand and the two grinding spindle stands.
By way of further illustration, the grinding spindle can be swung horizontally with the swinging groove for angle adjustment.
By way of further illustration, the swing groove and the height adjustment slide groove are in close engagement with each other.
The invention has the beneficial effects that:
1. the grooves are synchronously ground on the two sides of the double main shafts, so that the grinding efficiency of the cutter grooves is at least doubled;
2. the huge radial force generated during grinding is balanced symmetrically, so that the clamping rigidity of the bar stock during groove grinding is improved greatly, the function of a cutter following supporting system is achieved, and an additional cutter supporting system is not needed;
3. the groove grinding efficiency is improved, and meanwhile, the smoothness and quality of the cutter groove grinding are further improved by improving the clamping rigidity.
Drawings
FIG. 1 is a schematic diagram of the front view of a symmetrical double spindle tool groove grinder;
FIG. 2 is a schematic top view of the symmetrical double spindle tool groove grinder;
in the figure: 1. the grinding machine comprises a grinding machine seat, 2, a workpiece shaft upright post, 3, a grinding main shaft upright post, 4, a grinding main shaft, 5, a grooving grinding wheel, 6, a swinging groove, 7, a workpiece shaft workbench, 8, a workpiece shaft, 9 and a height adjusting chute.
Detailed Description
The technical scheme of the invention is described in more detail and completely below with reference to the accompanying drawings.
The symmetrical double-spindle cutter groove grinder comprises a workpiece shaft upright post 2, a grinding spindle upright post 3 and a grinder seat 1 arranged at the bottoms of the workpiece shaft 2 and the grinding spindle upright post 3, wherein a workpiece shaft 8 is fixedly connected to the workpiece shaft upright post 2, a workpiece shaft workbench 7 is fixedly connected to the lower part of the workpiece shaft upright post 2, the grinding spindle upright post 3 is respectively arranged at the left side and the right side in front of the workpiece shaft upright post 2 and is mutually opposite, a height adjusting chute 9 is arranged in the vertical direction of the grinding spindle upright post 3, a swinging groove 6 is arranged on the height adjusting chute 9, a grinding spindle 4 is connected to the swinging groove 6, and two slotting grinding wheels 5 are arranged on the grinding spindle 4;
a triangular structure is formed between the workpiece shaft upright post 2 and the two grinding main shaft upright posts 3;
the grinding main shaft 4 can horizontally swing along with the swinging groove 6 to adjust the angle;
the swinging groove 6 and the height adjusting chute 9 are tightly meshed with each other.
In the embodiment, as shown in fig. 1 and fig. 2, before the symmetrical double-spindle tool groove grinder is put into start, the tools to be machined are installed on a workpiece shaft, the heights of grinding spindle posts 3 on two sides are adjusted to adjust sliding grooves 9 to grind spindles 4 to proper heights respectively according to the characteristics of the tools of the workpiece, a slotting grinding wheel 5 is installed on the grinding spindle 4, then the grinding spindle 4 swings to the angle of the helix angle of a tool groove, and meanwhile, the slotting grinding wheels of the grinding spindle 4 on two sides synchronously move to the groove grinding position along the radial direction of the tools; after the groove grinding machine is started, the slotting grinding wheels 5 grind from the outer end of the cutter bar to the axial direction of the cutter clamping handle, the stress is uniform and symmetrical, and when rough grinding is finished, the two slotting grinding wheels 5 finish polishing reversely from the cutter clamping handle to the outer end of the cutter. If high-precision precise polishing is required, the second fine particles on the grooved grinding wheel rod are adopted to precisely throw away the grooved grinding wheel 5 until the cutter processing is completed.
It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other implementations, which can be made by those skilled in the art without the benefit of the teachings of this invention, are intended to be within the scope of this invention.
