Description

Technical Field

[0001] The present invention relates to the technical field of tool setting, involving one-time tool setting for an external tool and an internal tool, and particularly to a usage method for one-time tool setting of an external tool and an internal tool on the same runner. Background Art

[0002] Cutting tools are tools used for cutting in machining. Cutting tools are consumables necessary in daily tool machining. For some cutting tools, especially the turning tools used in lathes, since the cutting direction of the cutting tool tip is relatively single, some self-produced and processed factories, in order to reduce the increased cost caused by the breakage of the cutting tool, after the turning tool is damaged by machining, the damaged part is machined off so as to continue to be used to reduce the machining cost caused by tool replacement.

[0003] Turning tools can be divided into external tools and internal tools according to the machining orientation. Both the external tool and the internal tool are provided with two deflection angles. The first deflection angle is the machining deflection angle (tool edge angle), that is, the included angle formed between the tool and the workpiece when the tool contacts the workpiece. The second deflection angle is the installation orientation used to distinguish the external tool and the internal tool. Due to the different orientations of the second deflection angles of the external tool and the internal tool, the external tool and the internal tool cannot be machined and polished in the same batch.

[0004] Existing as Figure 1 shown in the runner grinding wheel machine tool for grinding cutting tools. The runner grinding wheel machine tool is provided with a rotatably mounted turntable and a grinding wheel. Among them, the turntable can be translated left and right, and the grinding wheel can be translated up and down and back and forth. The turntable is used to mount the tool holder, and the tool holder is used to mount a plurality of external tools and internal tools. A plurality of external tools and internal tools are distributed in an array around the rotation axis of the turntable. The number of external tools and internal tools is the same, and they are distributed in a ring according to the arrangement of one external tool and one internal tool. The first deflection angle and the second deflection angle on the external tool and the internal tool are formed by grinding with the grinding wheel. The first deflection angle is adjusted by rotating the turntable, and the orientation of the second deflection angle can be formed by the inclination setting of the turntable or the grinding wheel.

[0005] Before the external tool and the internal tool are ground, due to the annular distribution of the external tool and the internal tool, each time the tool holder is mounted on the turntable, the rotation orientation of the turntable needs to be repositioned. When tool setting, first manually align the external tool, and after grinding, then align the internal tool and grind it. The labor intensity is high, the tool setting is complex, the consistency of tool grinding is not good, and personnel are also required to wait, resulting in low efficiency. Summary of the Invention

[0006] Aiming at the problem that the runner grinding wheel machine tool needs two-time tool setting when simultaneously grinding an external tool and an internal tool, resulting in low efficiency, the technical problem to be solved by the present invention is to provide a usage method for one-time tool setting of an external tool and an internal tool on the same runner, which can realize grinding of both the external tool and the internal tool through one-time tool setting, and simplify and improve the efficiency of tool grinding.

[0007] The technical solution adopted by the present invention to solve the above technical problem is: a usage method for one-time tool setting of an external tool and an internal tool on the same runner, including a runner grinding wheel machine tool;

[0008] Among them, the turntable of the rotary wheel grinding machine can translate in the X-axis direction, and the grinding wheel of the rotary wheel grinding machine can translate in the Y-axis and Z-axis directions;

[0009] The intersection point of the rotation axis center of the turntable and the upper end surface of the turntable is the first coordinate point. The rotary wheel grinding machine is provided with a self-resetting coordinate position. After self-resetting, the coordinate position of the first coordinate point remains unchanged all the time;

[0010] It is characterized in that the first deflection angles of the outer tool and the inner tool are both ∠1, the included angle between the rightmost side of the adjacent outer tool and inner tool and the turntable axis center is ∠2, and the included angles between the rightmost side of the two outer tools / two inner tools and the turntable axis center are both ∠3;

[0011] The specific processing steps of the rotary wheel grinding machine for tool setting at one time are as follows:

[0012] Step 1: Select an outer tool on the tool disc as the tool for tool setting. Rotate the turntable so that the rightmost side of the tool for tool setting and the turntable axis center are both located on the YZ plane passing through the first coordinate point;

[0013] Step 2: Rotate the turntable clockwise by ∠1 + 90°, so that the tool for tool setting rotates to the outer tool processing position;

[0014] Step 3: The grinding wheel rotates, and the turntable moves in the X-axis direction, and the grinding wheel grinds the tool for tool setting;

[0015] Step 4: Repeat the processing of the remaining outer tools in a cycle. The number of cycles is 360°÷∠3÷2 - 1 times. During the cyclic operation, rotate the turntable clockwise by ∠3, and repeat Step 3;

[0016] Step 5: Rotate the turntable clockwise by ∠2 - 2∠1, and the inner tool adjacent to the counterclockwise position of the last processed outer tool rotates to the inner tool processing position;

[0017] Step 6: The grinding wheel rotates, and the turntable moves in the X-axis direction, and the grinding wheel grinds the inner tool at the inner tool processing position;

[0018] Step 7: Repeat the processing of the remaining inner tools in a cycle. The number of cycles is 360°÷∠3÷2 - 1 times. During the cyclic operation, rotate the turntable clockwise by ∠3, and repeat Step 6.

[0019] A further preferred solution of the present invention is that: the rotation axis center of the grinding wheel is always located on a YZ plane.

[0020] A further preferred solution of the present invention is that: the rotary wheel grinding machine is provided with a motor for driving the turntable to rotate, and the motor can control the rotation direction and angle of driving the turntable to rotate.

[0021] A further preferred solution of the present invention is that the rotary wheel grinding machine is provided with an outer cover, the turntable and the grinding wheel are both arranged inside the outer cover, and a window for replacing the tool disc or observing the machining situation inside the outer cover is provided on the outer cover.

[0022] A further preferred solution of the present invention is that the intersection point of the rotation axis of the grinding wheel and the rear end face of the grinding wheel is the second coordinate point, the upper end face of the turntable is the XZ plane. After self-resetting, the coordinate coefficients of the second coordinate point and the first coordinate point both return to zero, and the second coordinate point and the first coordinate point coincide in the X and Z axial directions. In the upward Y-axis direction, the second coordinate point is directly above the first coordinate point.

[0023] A further preferred solution of the present invention is that the outer diameter of the grinding wheel is known as φ1, and the grinding wheel is inclined. A second deflection angle for forming an external tool or an internal tool is formed between the rear end face of the grinding wheel and the upper end face of the turntable. The second deflection angle is ∠4, and the distance between the second coordinate point in the Y-axis direction and the upper end face of the turntable is H. Then, it can be calculated that:

[0024] The distance h1 between the lowest point of the rear end face of the grinding wheel in the Y-axis direction and the upper end face of the turntable is h1 = H - (φ1 / 2) * (cos∠4);

[0025] The distance m by which the lowest point of the rear end face of the grinding wheel deviates from the first coordinate point in the Z-axis direction is m = (φ1 / 2) * (sin∠4).

[0026] A further preferred solution of the present invention is that when the external tool and the internal tool are installed on the tool disc, the upper end faces of the external tool and the internal tool are set higher than the upper end face of the tool disc. The total height of the tool disc plus the external tool or the internal tool is h2, and h1 is always greater than h2.

[0027] A further preferred solution of the present invention is that the outer diameter of the tool disc is known as φ2. In step two and step five, the distance n in the X-axis direction between the lowest point of the rear end face of the grinding wheel and the first coordinate point is n = (φ2 / 2) * (cos∠1).

[0028] Compared with the prior art, the advantages of the present invention are that under the existing machining program of the machine tool, each time when tool setting, only the rightmost side of an external tool and the turntable axis need to be adjusted to the YZ plane passing through the first coordinate point, that is, the tool setting is completed. By rotating the turntable, the external tool or the internal tool can be adjusted to the machining position, and the grinding wheel can grind the external tool or the internal tool at the machining position, realizing the simplification and efficiency of tool grinding.

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0044] It should be noted that: Similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0045] This embodiment mainly elaborates on the usage method of one-time tool setting for the outer tool and the inner tool on the same runner, which can achieve grinding processing through one-time tool setting for both the outer tool and the inner tool, simplifying the tool sharpening and improving the efficiency. Specifically as follows:

[0046] As Figures 1 - 12 shown, the usage method of one-time tool setting for the outer tool and the inner tool on the same runner includes a runner grinding wheel 4 machine tool. The runner grinding wheel 4 machine tool is provided with a workbench 1 on the XZ plane and a side frame 2 on the XY plane. The workbench 1 is provided with a turntable 3 rotatably installed in the Y-axis direction, and the turntable 3 can translate along the X-axis direction. The side frame 2 is provided with a grinding wheel 4 rotatably installed, and the grinding wheel 4 can translate along the Y-axis direction and the Z-axis direction, and the rotation axis of the grinding wheel 4 is always located on a YZ plane.

[0047] In the existing machine tools, the turntable 3 and the grinding wheel 4 of each runner grinding wheel 4 machine tool have self-resetting initial positions. The intersection point of the rotation axis of the turntable 3 and the upper end surface of the turntable 3 is the first coordinate point 5, and the intersection point of the rotation axis of the grinding wheel 4 and the rear end surface of the grinding wheel 4 is the second coordinate point 6. After self-resetting, the coordinate coefficients of the first coordinate point 5 and the second coordinate point 6 both return to zero, and the coordinate positions of the first coordinate point 5 and the second coordinate point 6 always remain unchanged. At this time, the first coordinate point 5 and the second coordinate point 6 coincide in the X and Z axial directions, and in the Y-axis direction, the second coordinate point 6 is directly above the first coordinate point 5. Preferably, the upper end surface of the turntable 3 is the XZ plane.

[0048] During actual production, the same batch of specifications of grinding wheels 4 are selected, that is, the outer diameter sizes of all replaced grinding wheels 4 are the same. Therefore, after replacing the grinding wheels 4 of the same batch of specifications, it does not affect the operation of the original processing program.

[0049] The turntable 3 is used to install the cutter head 7, and the cutter head 7 is used to install a number of outer cutters 8 and inner cutters 9. A number of outer cutters 8 and inner cutters 9 are distributed in an array around the rotation axis of the turntable 3. The number of outer cutters 8 and inner cutters 9 is the same, and they are distributed in a ring in the order of one outer cutter 8 and one inner cutter 9. The formation of the first deflection angle and the second deflection angle on the outer cutter 8 and the inner cutter 9 is processed by grinding with a grinding wheel 4. In this embodiment, the first deflection angle is adjusted by rotating the turntable 3, and the direction of the second deflection angle is formed by the inclined setting of the grinding wheel 4, that is, an angle greater than 90° is formed between the rotation axis of the grinding wheel 4 and the rotation axis of the turntable 3.

[0050] In this embodiment, the processing of the first deflection angle of the outer cutter 8 and the inner cutter 9 is based on the XY plane passing through the first coordinate point 5 as the reference plane. The first deflection angle of the outer cutter 8 is the processing angle rotated clockwise around the axis of the turntable 3 through the reference plane, while the first deflection angle of the inner cutter 9 is the processing angle rotated counterclockwise around the axis of the turntable 3 through the reference plane.

[0051] Through alignment, it can be known that the distance from the Y-axis of the second coordinate point 6 to the upper end surface of the turntable 3 after self-resetting is H;

[0052] Through measurement, it is known that the outer diameter size of the grinding wheel 4 is φ1;

[0053] Because the grinding wheel 4 is inclined, and a second deflection angle to be processed for forming the outer cutter 8 or the inner cutter 9 is formed between the rear end surface of the grinding wheel 4 and the upper end surface of the turntable 3. The second deflection angle to be processed is ∠4, then the calculation shows that:

[0054] The distance h1 between the lowest point of the Y-axis of the rear end surface of the grinding wheel 4 and the upper end surface of the turntable 3 = H - (φ1 / 2) * (cos∠4);

[0055] The distance m by which the lowest point of the Z-axis of the rear end surface of the grinding wheel 4 deviates from the first coordinate point 5 = (φ1 / 2) * (sin∠4).

[0056] When the outer cutter 8 and the inner cutter 9 are installed on the cutter head 7, the upper end surfaces of the outer cutter 8 and the inner cutter 9 are set higher than the upper end surface of the cutter head 7. The total height of the cutter head 7 plus the outer cutter 8 or the inner cutter 9 is h2. To avoid the grinding wheel 4 directly contacting the outer cutter 8 or the inner cutter 9, h1 is always greater than h2 before processing, that is, the lowest point of the rear end surface of the grinding wheel 4 is higher than the outer cutter 8 and the inner cutter 9.

[0057] When the first deflection angles to be processed for the outer cutter 8 and the inner cutter 9 are both ∠1, and it is known through measurement or design of the cutter head 7 that the angle between the rightmost sides of adjacent outer cutters 8 and inner cutters 9 to the axis of the turntable 3 is ∠2, and the angles between the rightmost sides of two outer cutters 8 / two inner cutters 9 to the axis of the turntable 3 are both ∠3.

[0058] Such as Figure 1 、 Figure 2 And Figure 5As shown in the figure, a fixedly installed positioning frame 10 is provided on the workbench 1. The positioning frame 10 is in an inverted T-shaped or inverted 7-shaped structure. The positioning frame 10 is provided with a connected horizontal part 10-1 and a vertical part 10-2. The lower end surface of the horizontal part 10-1 is attached to and fixed on the workbench 1. The horizontal part 10-1 is parallel to the X axis. The vertical part 10-2 is arranged on the upper end surface of the horizontal plate, and the vertical part 10-2 is parallel to the Y axis.

[0059] A positioning sleeve 11 is detachably installed on the positioning frame 10. The positioning sleeve 11 is provided with a first insertion hole 11-1. A fastener 12 is threadedly connected to the positioning sleeve 11. The threaded section of the fastener 12 can be inserted into the first insertion hole 11-1. That is, when the positioning sleeve 11 is inserted over the vertical part 10-2 of the positioning frame 10 through the first insertion hole 11-1, rotating the fastener 12 can make the fastener 12 abut against the vertical part 10-2 of the positioning frame 10, and the fastener 12 limits and installs the positioning sleeve 11. Preferably, the first insertion hole 11-1 penetrates in the Y axis direction, and the threaded axis of the fastener 12 is perpendicular to the opening direction of the first insertion hole 11-1.

[0060] The positioning sleeve 11 is provided with a second insertion hole 11-2 that penetrates in the Z axis direction. The opening direction of the second insertion hole 11-2 is the same as or perpendicular to the threaded axis of the fastener 12. A tool setting block 13 that can be inserted into the second insertion hole 11-2 is provided. One side of the tool setting block 13 is provided with a positioning surface 13-1. The tool setting block 13 is in tool setting by fitting the positioning surface 13-1 with an outer tool 8 or an inner tool 9. In this embodiment, the positioning surface 13-1 is parallel to the YZ plane.

[0061] In this embodiment, when the outer tool 8 or the inner tool 9 is installed on the tool disc 7, the outer tool 8 or the inner tool 9 is each provided with a vertical surface 15 perpendicular to the XZ plane. The vertical surface 15 of any outer tool 8 or inner tool 9 passes through the axis of the turntable 3 and abuts against the rightmost side of the corresponding outer tool 8 or inner tool 9. The outer tools 8 or inner tools 9 provided on the tool disc 7 are each provided with two parallel clamping surfaces 16. The tool disc 7 is provided with an installation groove for placing the outer tool 8 or the inner tool 9, and an adjusting member 14 for clamping and fixing the outer tool 8 or the inner tool 9 on the outer ring of the tool disc 7. The adjusting member 14 can be rotationally adjusted through a threaded structure. Preferably, the installation groove communicates with the upper end surface and the outer ring of the tool disc 7.

[0062] When the outer tool 8 or the inner tool 9 is installed on the tool disc 7, one clamping surface 16 of the outer tool 8 or the inner tool 9 abuts against the groove wall of the installation groove of the tool disc 7 facing the outer ring of the tool disc 7. At this time, the clamping surface 16 of any outer tool 8 is perpendicular to the vertical surface 15 of the corresponding outer tool 8, and the clamping surface 16 of any inner tool 9 is perpendicular to the vertical surface 15 of the corresponding inner tool 9.

[0063] The specific processing steps for the first tool setting of the runner grinding wheel 4 machine tool are as follows:

[0064] Step 1: As Figure 8As shown, for the self-resetting grinding wheel 4 and the turntable 3, insert the tool setting block 13 into the second insertion hole 11-2 of the positioning sleeve 11. The positioning surface 13-1 of the tool setting block 13 is on the left side. At this time, both the positioning surface 13-1 of the tool setting block 13 and the axis of the turntable 3 are located on the YZ plane passing through the first coordinate point 5. Select an outer tool 8 on the tool disc 7 installed on the turntable 3 as the tool setting outer tool 8a. Rotate the turntable 3 so that the rightmost side of the tool setting outer tool 8a fits against the positioning surface 13-1 of the tool setting block 13. The starting position of the rotation of the turntable 3 is confirmed. At this time, the clamping surface 16 of the tool setting outer tool 8a is perpendicular to the positioning surface 13-1 of the tool setting block 13.

[0065] Step 2: As Figure 9 shown, rotate the turntable 3 clockwise by ∠1 + 90°, so that the tool setting outer tool 8a rotates to the machining position of the outer tool 8. At the same time, move the turntable 3 in the +X axis direction to the left, and move the grinding wheel 4 in the -Z axis direction backward, so that the grinding wheel 4 is in the position for pre-feed grinding of the outer tool 8;

[0066] Through measurement, it is known that the outer diameter of the tool disc 7 is φ2, and the distance in the X-axis direction between the lowest point of the rear end surface of the grinding wheel 4 and the first coordinate point 5 is n, and n = (φ2 / 2) * (cos∠1), that is, the turntable 3 is translated at least n in the +X axis direction;

[0067] And the distance that the lowest point of the rear end surface of the grinding wheel 4 is translated to the position for pre-feed grinding of the outer tool 8 is o = m + (φ2 / 2) * (sin∠1), that is, the grinding wheel 4 is moved backward by o in the -Z axis direction, so that the grinding wheel 4 is located on the right side and above the tool setting outer tool 8a.

[0068] Step 3: Rotate the grinding wheel 4 and move it downward in the -Y axis direction. Through measurement, it is known that the height of the tool disc 7 itself is h3. To avoid the grinding wheel 4 grinding the tool disc 7 and causing damage to the tool disc 7, during the actual grinding process of the outer tool 8 and the inner tool 9, the feed amount of the grinding wheel 4 in the -Y axis direction is less than the value of (h2 - h3), and the turntable 3 is moved to the right in the -X axis direction, and the grinding wheel 4 grinds the tool setting outer tool 8a;

[0069] Preferably, the grinding thickness of the outer tool 8 by the grinding wheel 4 can be controlled by moving the grinding wheel 4 backward in the -Z axis direction.

[0070] Step 4: After the grinding in Step 3 is completed, the grinding wheel 4 is reset to the position for pre-feed grinding of the outer tool 8, and the turntable 3 is rotated clockwise by ∠3, so that the next outer tool 8 rotates to the machining position of the outer tool 8, and repeat the grinding process in Step 3;

[0071] Preferably, this step is repeatedly processed until all the outer tools 8 are ground, and the total number of cycles in this step is 360°÷∠3÷2 - 1 times.

[0072] Step 5: Since the angle between the rightmost sides of the adjacent outer tool 8 and the inner tool 9 to the axis center of the turntable 3 is ∠2, the turntable 3 needs to rotate by an angle of ∠2 - 2∠1, so that the inner tool 9 adjacent to the counterclockwise position of the last processed outer tool 8 rotates to the inner tool 9 machining position, and at the same time, the grinding wheel 4 moves axially in the +Z direction to the position where the inner tool 9 pre-advances for grinding, that is, it moves axially in the +Z direction by a distance of (2 * sin∠1) at the position where the outer tool 8 pre-advances for grinding;

[0073] When the value calculated by ∠2 - 2∠1 is positive, the turntable 3 rotates clockwise;

[0074] When the value calculated by ∠2 - 2∠1 is negative, the turntable 3 rotates counterclockwise.

[0075] Step 6: The grinding wheel 4 rotates and moves downward along the -Y axis. The feed amount of the grinding wheel 4 along the -Y axis can refer to Step 3, and the turntable 3 moves to the right along the -X axis, and the grinding wheel 4 grinds and aligns with the outer tool 8a;

[0076] Step 7: After the grinding in Step 6 is completed, the grinding wheel 4 resets to the position where the inner tool 9 pre-advances for grinding, and the turntable 3 rotates clockwise by ∠3, so that the next inner tool 9 rotates to the inner tool 9 machining position, and repeats the grinding process in Step 6;

[0077] Preferably, this step is repeatedly processed until all the inner tools 9 are ground, and the total number of cycles of this step is 360°÷∠3÷2 - 1 times.

[0078] After the above processing steps are completed, the grinding wheel 4 and the turntable 3 both self-reset to the initial position. After replacing the tool holder 7 equipped with the outer tool 8 and the inner tool 9, since the sizes of the grinding wheel 4 and the tool holder 7 remain unchanged, the above processing steps and the original processing program during processing can be repeated.

[0079] In this embodiment, the rotary wheel grinding machine 4 is provided with a motor for driving the turntable 3 to rotate. The motor can control the turntable 3 to rotate clockwise or counterclockwise, and the motor can control the rotation angle of the turntable 3.

[0080] Since a large amount of sparks will be generated during the grinding process of the grinding wheel 4 during processing, for safety reasons, the rotary wheel grinding machine 4 can be provided with an outer cover, and the outer cover is provided with a window for replacing the tool holder 7 or observing the processing situation inside the outer cover. Since coolant is usually used to cool down during the grinding process of the grinding wheel 4 and the outer tool 8 or the inner tool 9, a sliding door can be provided at the window, and the sliding door can effectively prevent the coolant from splashing out.

[0081] Preferably, the positioning frame 10 is arranged at a position close to the window, that is, the positioning frame 10 is there after the sliding door is opened, which is convenient for the installation, alignment and disassembly of the positioning sleeve 11 and the tool alignment block 13.

[0082] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the inventive product is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0083] The above has introduced in detail the usage method of the primary tool setting of the outer tool and the inner tool on the same runner provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only for helping to understand the present invention and its core idea.
