However, in this machining method, the feed path of the R-angle tool is long, and the machining efficiency is low; moreover, all the removal in the machining process will grind the R-angle tool, resulting in fast wear of the R-angle of the tool and abnormal profile of the machined product.
In order to avoid the defects of the above processing method, another processing method is generally adopted in the prior art, that is, a forming tool is adopted, and a two-dimensional path program of the forming tool is programmed through a numerical control processing center, so that the forming tool moves along a two-dimensional path to form a required concave surface. However, in this machining method, the linear velocity of the tool is lower at a position closer to the axis of the tool, and therefore, the cutting ability is poorer and the wear is faster at a position closer to the axis of the tool, which causes rapid wear at the axis of the tool and results in large tool consumption; moreover, the profile surface of the forming cutter and the profile surface of the product structure are completely attached and contacted for grinding, the cooling and chip removal effects are poor, and the product is easily damaged.

The core of the invention is to provide a concave surface processing device which can avoid the phenomenon of serious local abrasion of a cutter and has better cooling and chip removal effects.

The invention provides a concave surface processing device, which is mainly applied to the concave surface forming processing of a 3D sapphire circular wafer and comprises a tool spindle 1 and a workpiece spindle 2, wherein the tool spindle 1 is used for arranging a tool, the workpiece spindle 2 is used for arranging a workpiece 02, the tool spindle 1 is connected with a first rotating mechanism 3, and the first rotating mechanism 3 is used for driving the tool spindle 1 to rotate in the processing process so that the tool spindle 1 drives the tool to rotate; the workpiece spindle 2 is connected with a second rotating mechanism 4, and the second rotating mechanism 4 is used for driving the workpiece spindle 2 to rotate in the machining process, so that the workpiece spindle 2 drives the workpiece 02 to rotate.
It should be noted that the specific structures of the first rotating mechanism 3 and the second rotating mechanism 4 are not limited in the present invention, as long as the first rotating mechanism 3 can drive the tool spindle 1 to rotate and the second rotating mechanism 4 can drive the workpiece spindle 2 to rotate, for example, both the first rotating mechanism 3 and the second rotating mechanism 4 may be motors.
It can be understood that the tool spindle 1 is provided with a tool clamping device for clamping a tool, and the specific structure of the tool clamping device is the same as that of a conventional tool clamping device in the prior art, and is not described herein again; the workpiece spindle 2 is provided with a workpiece clamping device for clamping the workpiece 02, and the specific structure of the workpiece clamping device is the same as that of a conventional workpiece clamping device in the prior art, and is not described in detail herein.
The main improvement of the present invention is that the workpiece spindle 2 and the tool spindle 1 are disposed in a non-parallel manner, that is, a predetermined included angle is formed therebetween, and the predetermined included angle is not equal to 180 °, so that a non-zero predetermined distance is formed between the cutting portion of the tool and the axis of the tool spindle 1.
That is, the invention improves the arrangement mode of the workpiece spindle 2 and the tool spindle 1 which are concentric and collinear in the prior art into the arrangement mode that a preset included angle is formed between the workpiece spindle 2 and the tool spindle 1 and is not equal to 180 degrees, so that part of the cutting part of the forming tool participates in cutting work, and the forming processing of the whole concave surface on the workpiece 02 is completed in cooperation with the rotation of the workpiece 02.
It should be noted that, in order to implement the processing of the workpiece 02, the workpiece spindle 2 and the tool spindle 1 may not be arranged in a coincident manner, that is, the preset included angle between the workpiece spindle 2 and the tool spindle 1 is obviously not equal to 0 °.
It can be understood that, when the workpiece spindle 2 and the tool spindle 1 are concentrically and collinearly arranged, the whole cutting portion of the formed tool participates in the cutting operation in the machining process, and since the linear velocity of the cutting portion of the tool located at the axis of the tool spindle 1 is zero, that is, the cutting portion of the tool located at the axis of the tool spindle 1 does not have cutting force, the amount to be machined of the corresponding portion of the workpiece 02 is removed by the friction force in the machining process, and the local wear of the tool is serious. Moreover, cooling and chip removal are difficult, the machined surface of the workpiece 02 is easily damaged, and the yield of products is low.
Therefore, in order to solve the above problems, in the present invention, the preset included angle between the workpiece spindle 2 and the tool spindle 1 is set to be not equal to 180 °, so that the cutting portion where the tool participates in cutting avoids the axis position of the tool spindle 1, and the condition that the linear velocity of the cutting portion of the tool participating in cutting is zero is avoided.
It can be understood that the preset distance between the cutting portion of the tool and the axis of the tool spindle 1 corresponds to the preset included angle between the tool spindle 1 and the workpiece spindle 2, and the preset distance between the cutting portion of the tool and the axis of the tool spindle 1 changes with the change of the preset included angle between the workpiece spindle 2 and the tool spindle 1.
it should be noted that, the specific value of the preset included angle is not limited in the present invention, the preset included angle is greater than 0 ° and smaller than 180 °, and a person skilled in the art can select a suitable preset included angle value according to actual needs.
Preferably, the preset included angle is greater than or equal to 90 degrees and smaller than 180 degrees.
More preferably, the preset included angle is 90 °, at this time, the linear cutting part of the tool for cutting the concave straight section is parallel to the axis of the tool spindle 1, so that the linear speed of the linear cutting part is equal everywhere, so as to ensure the uniformity of the processing quality of the concave straight section and the uniformity of the wear of the tool linear cutting part.
on the other hand, in the machining process, because the cutter and the workpiece 02 rotate relatively at a preset included angle, the cutting part of the cutter is not in complete contact with the surface to be machined of the workpiece, and particularly when the preset included angle between the cutter spindle 1 and the workpiece spindle 2 is 90 degrees, the cutting part of the cutter is in line contact with the surface to be machined of the workpiece, compared with the prior art that the cutting part of the cutter is in complete contact with the surface to be machined of the workpiece, the friction force between the cutter and the workpiece 02 is small, and the abrasion of the cutter can be reduced; meanwhile, the cooling and chip removal are facilitated, and the yield of products is high; further, in the machining process, the workpiece spindle 2 drives the workpiece 02 to rotate, and the path machining of the cutter is replaced, so that the machining efficiency is improved.
in order to enable a person skilled in the art to adjust the preset included angle between the workpiece spindle 2 and the tool spindle 1 according to actual needs, on the basis of the above-mentioned embodiments, the angle of at least one of the workpiece spindle 2 and the tool spindle 1 is adjustable, so as to adjust the preset included angle.
That is, in the present embodiment, the preset included angle between the workpiece spindle 2 and the tool spindle 1 is adjustable, and the preset included angle between the workpiece spindle 2 and the tool spindle 1 can be changed by adjusting the angle of at least one of the two.
It should be noted that, in the present embodiment, the angle adjustment manner of the workpiece spindle 2 and/or the tool spindle 1 is not specifically limited, for example, the tool spindle 1 may be rotatably disposed on the worktable 01 through the first rotating mechanism 3; and/or the workpiece spindle 2 is rotatably arranged on the working table 01 by a second rotating mechanism 4.
Preferably, the tool spindle 1 is connected to an angle adjustment mechanism for adjusting the angle of the tool spindle 1. That is, the angle of the tool spindle 1 in the present embodiment is adjustable, and thus the preset included angle between the tool spindle 1 and the workpiece spindle 2 is changed by adjusting the angle of the tool spindle 1.
In view of the simplicity of the specific structure of the angle adjustment mechanism and the ease of implementation, on the basis of the above-described embodiment, the angle adjustment mechanism includes the rotary plate 51 for fixed connection with the first rotation mechanism 3, and the rotary plate 51 is provided with the rotating portion for rotational connection with the table 01.
That is to say, in this embodiment, the rotation of the turntable 51 relative to the workbench 01 can be realized through the rotation portion, and then the first rotation mechanism 3 fixed on the turntable 51 is driven to rotate, so that the first rotation mechanism 3 drives the tool spindle 1 to rotate synchronously, thereby achieving the purpose of adjusting the angle of the tool spindle 1.
It can be understood that the position of the turntable 51 after the angle adjustment can be ensured by increasing the gravity and the volume of the turntable 51.
In view of the light weight of the rotary table 51, in order to avoid the tool spindle 1 from being dislocated due to vibration and the like during machining, the angle adjusting mechanism preferably further includes a positioning device for fixing the rotary table 51 after the rotary table 51 is adjusted in position.
That is to say, in this embodiment, after the turntable 51 is adjusted in place, the turntable 51 is fixed by the positioning device, so as to prevent the tool spindle 1 from deviating from the position during the machining process, which results in a deviation of the preset included angle between the tool spindle 1 and the workpiece spindle 2.
it should be noted that the specific structure of the positioning device is not limited in this embodiment, for example, the positioning device may include positioning pin holes respectively disposed at corresponding positions of the turntable 51 and the worktable 01, and positioning pins inserted into the positioning pin holes for positioning the turntable 51 and the worktable 01.
Of course, the positioning device may also be a pressure device for applying a positive pressure to the rotating disk 51 after the rotating disk 51 is adjusted in position, and the positive pressure applied to the rotating disk 51 by the pressure device avoids the position deviation of the rotating disk 51 during the machining process.
in order to monitor the rotation angle of the rotary disk 51 in real time, the angle adjusting mechanism further includes a scale 52 for measuring the rotation angle of the rotary disk 51 on the basis of the above-described embodiment.
That is, the rotation angle of the turntable 51 can be measured in real time by the dial 52 during the rotation of the turntable 51, thereby ensuring the accuracy of the angular adjustment of the turntable 51.
In order to ensure that the tool spindle 1 and the workpiece spindle 2 have the correct relative position after changing the angle of the tool spindle 1, on the basis of the above-described embodiment, the first rotation mechanism 3 is connected to the tool moving pallet 61, and the turntable 51 is provided with a tool moving guide 62 for sliding connection with the tool moving pallet 61.
That is, in the present embodiment, the first rotating mechanism 3 is connected to the turntable 51 by slidably connecting the tool moving blade 61 to the tool moving rail 62. The angle of the first rotating mechanism 3 is adjusted by the turntable 51, and the first rotating mechanism 3 is driven to move by the sliding of the tool moving supporting plate 61 along the tool moving guide rail 62, that is, when the angle of the turntable 51 is adjusted, the distance between the first rotating mechanism 3 and the workpiece spindle 2 is adjusted, so that the tool spindle 1 and the workpiece spindle 2 have correct relative positions while a preset included angle is ensured.
It should be noted that, in the present embodiment, the moving direction of the tool moving supporting plate 61 (that is, the extending direction of the tool moving guide 62) is not specifically limited, as long as it is ensured that when the tool moving supporting plate 61 moves along the tool moving guide 62, the first rotating mechanism 3 can drive the tool spindle 1 to approach or leave the workpiece spindle 2.
Preferably, the tool moving guide 62 is a V-shaped guide, and the tool moving blade 61 is provided with a slide groove for cooperating with the V-shaped guide.
In consideration of the fact that the depth of the surface to be processed of the workpiece is larger, the machining device further comprises a propelling mechanism which is connected with the second rotating mechanism 4 and is used for driving the workpiece spindle 2 to feed.
That is, the present embodiment realizes the feeding of the workpiece 02 during the machining process by the advancing mechanism, thereby ensuring that the workpiece 02 has a sufficient cutting amount.
