Abstract
A kind of multithreading abrasive grinding wheel mechanism including emery wheel, there are two the arc annular tooth extended above out on emery wheel outer periphery, matches, arc ring shape between cog has annular space slot with workpieces processing shape.It integrates corase grinding, half fine grinding, the shape of finishing wheel, function, in clamped one time grinding, emery wheel rotation translation, the corase grinding to workpiece, half fine grinding, fine grinding are completed simultaneously, thoroughly change former grinding processing method, the time used in exchanging and debugging emery wheel progress grinding is saved, reduces labor intensity, greatly increases the production efficiency significantly.Matched using big emery wheel arc annular tooth with workpiece shapes, contact surface is small therebetween, reduces grinding resistance and grinding heat, ensures that emery wheel processing tooth form is hardly damaged, while high precision machining ensures product processing quality.In addition emery wheel is modified using emery wheel, three on emery wheel groove modifies three arc annular tooths on emery wheel simultaneously, greatly reduces the finishing time of emery wheel, reduces production cost.
Description
Technical field
The utility model is related to raceway grooves on a kind of grinding mechanism, particularly a kind of suitable grinding ball screw to make
Multithreading abrasive grinding wheel mechanism.
Background technology
In the raceway groove grinding production of ball screw, ball screw at the uniform velocity rotates, and emery wheel is rotated and put down along screw axial direction
It moves, but has deformation, more demanding channel surface quality and different channel dimensions afterwards because screw is thermally treated, usually also need
Emery wheel is repeatedly back and forth ground, and can be only achieved processing request, common grinding mode production efficiency is relatively low, and emery wheel is anti-
During regrinding is cut, abrasion of grinding wheel, it is difficult to ensure that the tooth form of emery wheel is constant, so as to cause the raceway groove for the ball screw processed by it
Shape is overproof, influences product processing quality.
Patent No. CN200820116414.0 " copy grinding wheel ", provide a kind of contour shape for making emery wheel maintain it is higher
Accuracy, it is also cost-effective.
The content of the invention
Technical problem to be solved in the utility model is：A kind of multithreading abrasive grinding wheel mechanism is provided, it is simple in structure, easy
Fabrication and installation in a grinding, by the rotation of emery wheel, translation, while complete the corase grinding to workpiece, half fine grinding, essence
Mill, greatly improves the grinding efficiency to workpiece, grinding quality has been effectively ensured.
The technical scheme in the invention for solving the above technical problem is：Multithreading abrasive grinding wheel mechanism, including emery wheel,
There are two the arc annular tooth that extends above out on the outer periphery of the emery wheel, match with the shape of institute workpiece, the arc ring
Shape between cog has annular space slot.
Compared with prior art, the utility model has the advantage of, multithreading abrasive grinding wheel mechanism, simple in structure, easy systems
It installs, also low manufacture cost, because it integrates corase grinding, half fine grinding, the shape of finishing wheel, function, therefore is once filling
It presss from both sides in grinding, emery wheel rotation translation can complete the corase grinding to workpiece, half fine grinding, fine grinding, thoroughly change former need simultaneously
After first roughly grinding, then the emery wheel of half fine grinding is replaced, the processing method being finally ground again with finishing wheel, this emery wheel mechanism is
The time replaced and debugged used in emery wheel progress grinding has been saved, has also reduced labor intensity significantly, greatly improves life
Efficiency is produced, the grinding tooth form on emery wheel matches with workpieces processing shape, and contact surface therebetween is small, reduction grinding resistance and grinding
Heat ensure that the tooth form of emery wheel is hardly damaged, while using CBN（Cubic boron nitride）Abrasive material is the emery wheel of raw material, and grinding is smart
Higher is spent, so as to ensure that the processing quality of product, in addition emery wheel is modified using emery wheel, three on emery wheel
A groove can modify the tooth of three sizes on emery wheel simultaneously, therefore greatly reduce the finishing time of emery wheel again.
Description of the drawings
The use state reference chart of Fig. 1, the utility model.
Fig. 2, circumference of emery wheel arc-shaped gear are to ball screw raceway groove machining sketch chart（Enlarged drawing）.
Fig. 3, Diamant roller carry out finishing schematic diagram to emery wheel.
Specific embodiment
The embodiment of the utility model is further described below in conjunction with the accompanying drawings.
Discoidal emery wheel 3 has the raised and intermediate taper type for having through hole among two outer surfaces, have on outer periphery it is uniformly distributed simultaneously
The three arc annular tooths extended outward, wherein the second arc annular tooth 6 is as 5 shape of the first arc annular tooth, but diameter is big
In the 3~5% of the first arc annular tooth 5.The diameter of 3rd arc annular tooth 7 is greater than the 1~3% of the second arc annular tooth 6, but shape phase
Together.By three arc annular tooths on emery wheel 3, shape matches with 9 shape of raceway groove on ball screw 2, to the ditch of ball screw 2
Road 9 carries out grinding.
Emery wheel 3 is relatively large in diameter, generally 10~20 times of workpieces processing diameter, low in grinding wheel spindle because grinding wheel diameter is big
Under conditions of rotating speed, the linear velocity of emery wheel is effectively ensured, grinding of being more convenient for makes the precision higher of processing, surface is more smooth,
It is bright.
First arc annular tooth 5 for roughly grinding, for half refine by the second arc annular tooth 6, and the 3rd arc annular tooth 7 is used to refine,
Three arc ring shape between cog have identical uniformly distributed interval trough 8.
Interval trough 8 is the distance of adjacent two arc rings shape between cog, is determined according to the helical pitch of institute's workpieces processing grinding ball screw.
During processing, in the opening of one end insertion chuck 1 of workpiece ball screw 2 and clamp, the other end of ball screw
It is withstood with top 4, as shown in Figure 1.
Chuck 1 is connected on main shaft（Figure is not drawn）, by main shaft chuck is driven to rotate, chuck 1 drives 2 turns of ball screw again
Dynamic, emery wheel 3 is fixed on in-between through hole on grinding wheel spindle（Figure is not drawn）, and by grinding wheel spindle emery wheel 3 is driven to rotate, together
When emery wheel also moved in parallel along the axial direction of ball screw 2, and make to generate opposite spiral fortune between ball screw 2 and emery wheel 3
It is dynamic, so as to carry out grinding with the spiral shape raceway groove 9 on first, second, third arc annular tooth, 5,6,7 pairs of ball screws 2,
Emery wheel 3 moves one time along ball screw axial direction, from right to left axial direction, and to position shown in Fig. 2, at this moment ball screw is complete
Into from corase grinding to half fine grinding, the whole grindings of fine grinding.
Emery wheel 3 is modified using emery wheel 10, i.e., three grooves on Diamant roller 10 correspond to the on emery wheel 3 respectively
First, second, third arc annular tooth 5,6,7, matches with its shape, size, it is modified, and disposably completes finishing, such as
Shown in Fig. 3.
