Description

Technical Field

[0001] The present invention relates to the field of machine tool equipment, and particularly to a cutting tool applicable to a machining center machine tool with a W-axis and the machining center machine tool. Background Art

[0002] In the context of machining, a cutting tool is any tool that is mounted on a machine tool and removes some material from a workpiece by shear deformation. Cutting can be done with single-point or multi-point tools. Single-point tools are used for turning, profiling, planing, and similar operations and remove material with a single cutting edge. Milling and drilling tools are usually multi-point tools.

[0003] However, existing cutting tools can only perform cutting on the surface of the workpiece. If it is necessary to machine a large-diameter hole inside a small hole, it is very difficult for existing cutting tools to achieve, which is a technical problem in this field. Summary of the Invention

[0004] To overcome the above disadvantages, the purpose of the present invention is to provide a cutting tool applicable to a machining center machine tool with a W-axis and the machining center machine tool that can machine a large-diameter hole inside a small hole.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: the machine tool applicable to the cutting tool is a machining center machine tool with a programmable control W-axis. When it is necessary to machine a large-diameter hole inside a small hole, the cutting tool is installed on the machine tool spindle.

[0006] The cutting tool applicable to the machining center machine tool with a W-axis includes a tool body. There is a hollow cavity inside the tool body. A push rod is arranged in the hollow cavity. The push rod can move relative to the hollow cavity. A plurality of guide bars are arranged at one end of the push rod. The guide bars are inclined relative to the axis of the push rod. The plurality of guide bars are arranged parallel to each other. A slider boring bar is arranged on one side of the guide bars. The guide bars can drive the slider boring bar to generate displacement in a direction perpendicular to the push rod under the drive of the push rod. The push rod drives the guide bars to move obliquely relative to the slider boring bar. Since the slider boring bar is fixed in the axial direction of the push rod and cannot move axially, it can only generate displacement in the radial direction perpendicular to the axis of the push rod. A cutting head is connected to the slider boring bar. The cutting head is used for cutting the workpiece.

[0007] The push rod is connected to the W-axis of the machine tool. When machining a large-diameter hole in a small hole, the XY-axes of the machine tool are positioned at the center of the small hole, and the Z-axis of the machine tool drives the cutting tool to move into the hole. The W-axis of the machine tool extends to push the push rod forward. Since the slider boring bar is fixed axially, under the guidance of the guiding strip, the slider boring bar generates a displacement in the radial direction, and the slider boring bar moves outward relative to the tool body, thereby driving the cutting head to move outward from the tool body, making the diameter of the circle formed by the rotation of the cutting head larger, so that the function of machining a large hole in a small hole can be realized.

[0008] On the contrary, when the machining of the large hole in the small hole is completed, the W-axis of the machine tool pulls the push rod backward. Under the guidance of the guiding strip, the cutting head moves inward toward the tool body along with the slider boring bar, so that the cutting head is hidden inside the tool body, and then the cutting tool is moved out of the small hole.

[0009] The push rod of this application moves forward under the push of the W-axis of the machine tool. The slider boring bar generates a displacement in the radial direction under the guidance of the guiding strip, making the diameter of the circle formed by the rotation of the cutting head increase, so that the technical problem of machining a large hole in a small hole can be solved. At the same time, the structure of this application is simple and the operation is convenient. This application is suitable for cavity machining inside deep holes.

[0010] Specifically, the angle A between the guiding strip and the axis of the hollow cavity is 26.5651 degrees. For the convenience of programming control, the angle A between the guiding strip and the axis of the hollow cavity is set to 26.5651 degrees. The specific principle is as follows: at this fixed angle, when the push rod is pushed forward 1 mm axially, the slider boring bar drives the cutting head to move 0.5 mm radially (tan26.5651≈0.5 / 1≈0.5 mm), that is, the diameter of the inner hole cut by the cutting head increases by 1 mm. At this fixed angle, there is a fixed ratio between the size change of the diameter of the hole to be machined and the size of the movement of the push rod, that is, the fixed ratio is 1:1. Therefore, the programming controls how much the W-axis extends according to how much the diameter of the machined hole needs to change, which is convenient for programming control.

[0011] Furthermore: a guiding groove is provided at the corresponding position of the slider boring bar and the guiding strip. The guiding groove is parallel to the guiding strip. When the push rod moves axially, the guiding strip moves along the guiding groove, preventing the guiding groove from running off in the inclined movement direction under the drive of the axial force, and being able to accurately drive the radial movement of the slider boring bar, so that the machining accuracy of the inner hole is higher.

[0012] Furthermore: One end of the push rod close to the guiding strip is arranged as a flat part, and the thickness of the flat part is smaller than the diameter of the push rod, so that the guiding strip can be located inside the tool body without increasing the diameter of the tool body and can extend into a small hole. One side of the flat part close to the guiding strip is arranged as a flat surface, the guiding strip is arranged on the flat surface, and the slide block boring bar slides along the flat surface, improving the stability of the slide block boring bar during the sliding process. The opposite surface of the flat part to the flat surface is an arc surface (i.e., the arc surface of the original push rod), the arc surface is in precise contact with the inner side of the tool body, and the arc surface of the flat part moves along the tool body.

[0013] Furthermore: A connecting block is detachably connected to the slide block boring bar, and the cutting head is fixed on the connecting block, facilitating the replacement of the cutting head.

[0014] Furthermore: A protective cover is arranged on the outer surface of the slide block boring bar, and an opening is arranged at the corresponding position of the protective cover to the connecting block, and the connecting block and the cutting head extend into or out of the protective cover along the opening. On the one hand, the protective cover is used to protect the slide block boring bar and the cutting head, preventing impurities such as chips from entering the inside of the protective cover and affecting the smooth movement of the guiding strip, thereby preventing the accuracy of the movement of the slide block boring bar from being affected. On the other hand, the protective cover is used to position the slide block boring bar to prevent the axial movement of the slide block boring bar. The connecting block drives the cutting head to extend into or out of the opening to prevent the slide block boring bar and the connecting block from deviating during the radial movement.

[0015] Furthermore: The connecting block and the slide block boring bar are quickly positioned through a positioning block and a positioning groove.

[0016] Furthermore: A placement groove is arranged at the corresponding position of the inner side of the tool body to the flat part, and a copper sleeve is in interference fit in the placement groove. The copper sleeve is pressed into the placement groove and fixed on the tool body by screws. The inner side wall of the copper sleeve is smooth with the inner side wall of the tool body, and there is no height difference between them.

[0017] Since the matching accuracy requirement between the front end of the push rod (i.e., the flat part) and the inner side of the tool body is relatively high, the corresponding positions of the front end of the push rod and the tool body are worn against each other. Also, since the manufacturing cost of the push rod is too high, it cannot be frequently replaced; now a copper sleeve is used to replace the inner side of the tool body in contact with the front end of the push rod. When the copper sleeve is in contact with the front end of the push rod, it is the copper sleeve that is worn instead of the push rod and the tool body. The copper sleeve is convenient to replace and has a low cost.

[0018] Furthermore: A support rod is detachably connected to the end of the protective cover away from the push rod. Since the tool has too long a cantilever when machining a deep hole, which reduces the rigidity of the tool, using the support rod can support the tool body so that the rigidity of the tool will not be reduced when it is cantilevered.

[0019] One end of the support rod away from the slider boring is provided with a support sleeve for supporting the support rod.

[0020] Furthermore: The tool body includes a tool holder and a sleeve. The tool holder is detachably connected to the sleeve, and an extension tube can be added between the tool holder and the sleeve so as to be applicable to holes of different depths. The sleeve is arranged on the outer surface of the push rod, and the push rod moves along the sleeve. A through hole is arranged on the inner surface of the tool holder, so that the push rod can pass through the tool holder and be connected to the W-axis of the machine tool.

[0021] A machining center machine tool includes a machine tool body and a cutting tool. A machine tool spindle is arranged on the machine tool body. The machine tool spindle is connected to the tool body through a connecting flange. A connecting shank is arranged inside the machine tool spindle. The connecting shank is connected to the W-axis of the machine tool, and the W-axis of the machine tool is fixedly connected to the push rod. The machine tool spindle drives the cutting tool to rotate, and the W-axis of the machine tool drives the push rod to axially move, thereby driving the cutting head to generate a radial displacement, so as to change the diameter of the circle formed by the rotation of the cutting head.

[0022] The beneficial effect of the present invention is that the push rod of the present application moves forward under the push of the W-axis of the machine tool, and the slider boring generates a radial displacement under the guidance of the guide bar, so that the diameter of the circle formed by the rotation of the cutting head increases, thereby being able to solve the technical problem of machining a large hole in a small hole. At the same time, the structure of the present application is simple and the operation is convenient. The present application is applicable to cavity machining inside deep holes.

[0023] The present application uses a copper sleeve to replace the inner side of the tool body in contact with the front end of the push rod. When the copper sleeve contacts the front end of the push rod, it is the copper sleeve that wears instead of the push rod and the tool body. The copper sleeve is convenient to replace and has a low cost.

[0024] The use of the support rod and the support sleeve in the present application can enable the cutting tool to meet the stiffness requirements even when it is overhanging. Description of the Drawings

Detailed implementation manners

[0040] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] See Figures 1 - 3 As shown, an embodiment of the present application provides a cutting tool applicable to a machining center machine tool with a W-axis. The machine tool applicable to this cutting tool is a machining center machine tool with a programmable control W-axis. When it is necessary to machine a large-diameter hole in a small hole, the cutting tool is installed on the spindle of the machine tool.

[0043] The cutting tool applicable to the machining center machine tool with a W-axis includes a tool body 1. There is a hollow cavity inside the tool body 1, and the tool body 1 is in a cylindrical structure; a push rod 2 is arranged in the hollow cavity, and the push rod 2 can move relative to the hollow cavity. A plurality of guide bars 3 are arranged at one end of the push rod 2. The guide bars 3 are inclined relative to the axis of the push rod 2, and the plurality of guide bars 3 are arranged parallel to each other. A slider boring bar 4 is arranged on one side of the guide bars 3. The guide bars 3 can drive the slider boring bar 4 to generate a displacement in a direction perpendicular to the push rod 2 under the drive of the push rod 2. Specifically, the push rod 2 drives the guide bars 3 to move obliquely relative to the slider boring bar 4. Since the slider boring bar 4 is fixed in the axial direction of the push rod 2 and cannot move axially, it can only generate a displacement in the radial direction perpendicular to the axis of the push rod 2.

[0044] A cutting head 5 is connected to the slider boring bar 4, and the cutting head 5 is used for cutting the workpiece.

[0045] Machining a large hole inside a small hole means machining a cavity inside the hole.

[0046] The guiding bar 3 can be inclined to the left or right relative to the axis of the push rod 2, and the cutting head 5 is arranged on the inclined side of the guiding bar 3. For example, if the guiding bar 3 is inclined to the left relative to the axis of the push rod 2, the cutting head 5 is arranged on the left side of the slider boring 4; or if the guiding bar 3 is inclined to the right relative to the axis of the push rod 2, the cutting head 5 is arranged on the right side of the slider boring 4. In this embodiment, the guiding bar 3 is inclined to the left relative to the axis of the push rod 2, and at the same time the cutting head 5 is arranged on the left side of the slider boring 4.

[0047] The push rod 2 is connected to the W-axis 500 of the machine tool. When a large-diameter hole needs to be machined in a small hole, the X-axis and Y-axis of the machine tool are positioned at the center of the small hole, and the Z-axis of the machine tool drives the cutting tool to move into the hole. The W-axis 500 of the machine tool extends to push the push rod 2 forward (i.e., move in the direction close to the slider boring 4). Since the slider boring 4 is fixed axially, under the guidance of the guiding bar 3, the slider boring 4 generates a radial displacement. The slider boring 4 moves outward relative to the tool body 1, thereby driving the cutting head 5 to move outward relative to the tool body 1, so that the diameter of the circle formed by the rotation of the cutting head 5 becomes larger, thus enabling the function of machining a large hole in a small hole.

[0048] On the contrary, when the machining of the large hole in the small hole is completed, the W-axis 500 of the machine tool pulls the push rod 2 backward. Under the guidance of the guiding bar 3, the cutting head 5 moves inward relative to the tool body 1 along with the slider boring 4, so that the cutting head 5 is hidden inside the tool body 1, and the Z-axis of the machine tool drives the cutting tool to move out of the small hole.

[0049] The push rod 2 of the present application moves forward under the push of the W-axis 500 of the machine tool, and the slider boring 4 generates a radial displacement under the guidance of the guiding bar 3, so that the diameter of the circle formed by the rotation of the cutting head 5 increases, thereby being able to solve the technical problem of machining a large hole in a small hole. At the same time, the structure of the present application is simple and the operation is convenient. The present application is applicable to cavity machining inside deep holes.

[0050] Specifically, the angle A between the guiding bar 3 and the axis of the hollow cavity is 26.5651 degrees. For the convenience of programming control, the angle A between the guiding bar 3 and the axis of the hollow cavity is set to 26.5651 degrees. The specific principle is as follows: at this fixed angle, when the push rod 2 is pushed forward 1 mm axially, the slider boring 4 drives the cutting head 5 to move 0.5 mm radially (perpendicular to the axis of the push rod 2), that is, the diameter of the inner hole cut by the cutting head 5 increases by 1 mm. At this fixed angle, there is a fixed ratio between the dimension change of the diameter of the hole to be machined and the dimension of the movement of the push rod 2, that is, the fixed ratio is 1:1. Therefore, how much the diameter of the machined hole needs to change is programmed to control how much the W-axis extends, which is convenient for programming control.

[0051] The present application does not limit the angle of the angle A, as long as it is convenient for programming control.

[0052] On the basis above, as Figure 4 shown, a guiding groove 6 is arranged at the corresponding position of the slide block boring tool 4 and the guiding bar 3. The guiding groove 6 is parallel to the guiding bar 3. When the push rod 2 axially moves, the guiding bar 3 moves along the guiding groove 6, preventing the guiding groove 6 from deviating in the inclined moving direction under the drive of the axial force, and being able to accurately drive the radial movement of the slide block boring tool 4, so that the machining accuracy of the inner hole is higher.

[0053] On the basis above, as Figure 5 shown, one end of the push rod 2 close to the guiding bar 3 is set as a flat part 7. The thickness of the flat part 7 is smaller than the diameter of the push rod 2, so that the guiding bar 3 can be located inside the tool body 1 without increasing the diameter of the tool body 1 and can extend into a small hole. One surface of the flat part 7 close to the guiding bar 3 is set as a flat surface. The guiding bar 3 is arranged on the flat surface, and the slide block boring tool 4 slides along the flat surface, improving the stability of the slide block boring tool 4 during the sliding process. The opposite surface of the flat part 7 to the flat surface is an arc surface (i.e., the arc surface of the original push rod 2). The arc surface is in precise contact with the inner side of the tool body 1, and the arc surface of the flat part 7 moves along the tool body 1.

[0054] On the basis above, as Figure 4 shown, a connecting block 8 is detachably connected to the slide block boring tool 4, and the cutting head 5 is fixed on the connecting block 8. When the cutting head 5 needs to be replaced, the connecting block 8 can be detached from the slide block boring tool 4, which is convenient for replacing the cutting head 5.

[0055] On the basis above, as Figure 6 shown, a protective cover 9 is arranged on the outer surface of the slide block boring tool 4. An opening 10 is arranged at the corresponding position of the protective cover 9 and the connecting block 8. The connecting block 8 and the cutting head 5 extend into or out of the protective cover 9 along the opening 10. On the one hand, the protective cover 9 is used to protect the slide block boring tool 4 and the cutting head 5, preventing impurities such as material chips from entering the inside of the protective cover 9 and affecting the smooth movement of the guiding bar 3, thereby preventing the movement accuracy of the slide block boring tool 4 from being affected. On the other hand, the protective cover 9 is used to position the slide block boring tool 4 to prevent the axial movement of the slide block boring tool 4. The connecting block 8 drives the cutting head 5 to extend into or out of the opening 10 to prevent the slide block boring tool 4 and the connecting block 8 from deviating during the radial movement.

[0056] On the basis above, as Figure 6As shown, the connecting block 8 and the slider boring 4 are quickly positioned through the positioning block 11 and the positioning groove 12, and the connecting block 8 and the slider boring 4 are connected by screws. When it is necessary to replace the cutting head 5, remove the screws fixing the connecting block 8 and the slider boring 4 and then remove the connecting block 8. Align the positioning block 11 and / or the positioning groove 12 on the connecting block 8 to be installed with the positioning groove 12 and / or the positioning block 11 on the slider boring 4, and then use screws to lock the connecting block 8 and the slider boring 4. The positioning is convenient and accurate.

[0057] Specifically, a positioning block 11 can be provided on the connecting block 8 and a positioning groove 12 can be provided on the slider boring 4. Or a positioning groove 12 can be provided on the connecting block 8 and a positioning block 11 can be provided on the slider boring 4. Or both a positioning block 11 and a positioning groove 12 can be provided on the connecting block 8, and both a positioning block 11 and a positioning groove 12 can be provided on the slider boring 4. No matter which of the above setting methods is used, the positioning block 11 or the positioning groove 12 on the connecting block 8 needs to correspond to the positioning groove 12 or the positioning block 11 on the slider boring 4 in position and can cooperate with each other to achieve quick positioning.

[0058] On the above basis, as Figures 7 - 8 shown, a placement groove is provided at the corresponding position between the inner side of the tool body 1 and the flat part 7. An interference fit copper sleeve 13 is arranged in the placement groove. The copper sleeve 13 is pressed into the placement groove and fixed on the tool body 1 by screws. The inner side wall of the copper sleeve 13 is smooth with the inner side wall of the tool body 1, and there is no height difference between them.

[0059] Since the matching accuracy requirement between the front end of the push rod 2 (i.e., at the flat part 7) and the inner side of the tool body 1 is relatively high, the corresponding positions between the front end of the push rod 2 and the tool body 1 are worn against each other. Also, since the manufacturing cost of the push rod 2 is too high, it cannot be replaced frequently. Now, the copper sleeve 13 is used to replace the inner side of the tool body 1 that contacts the front end of the push rod 2. When the copper sleeve 13 contacts the front end of the push rod 2, it is the copper sleeve 13 that is worn instead of the push rod 2 and the tool body 1. The copper sleeve 13 is convenient to replace and has a low cost.

[0060] On the above basis, as Figure 9 shown, one end of the protective cover 9 away from the push rod 2 is detachably connected with a support rod 14. Since the tool overhangs too long during deep hole machining, the rigidity of the tool is reduced. Using the support rod 14 can support the tool body 1 so that the rigidity of the tool will not be reduced when it overhangs.

[0061] A support sleeve 15 is arranged at one end of the support rod 14 away from the slider boring 4, and the support sleeve 15 is used to support the support rod 14.

[0062] During use, first install the support sleeve 15 into the hole through a tool and then tighten it. The front end of the support rod 14 extends into the support sleeve 15 to achieve support.

[0063] On the above basis, as Figures 10 - 11 shown, the tool body 1 includes a tool holder 16 and a sleeve 17. The tool holder 16 is detachably connected to the sleeve 17. An extension cylinder can be increased between the tool holder 16 and the sleeve 17 so that it can be applicable to holes of different depths. The sleeve 17 is arranged on the outer surface of the push rod 2, and the push rod 2 moves along the sleeve 17. A through hole is arranged on the inner surface of the tool holder 16 so that the push rod 2 can pass through the tool holder 16 and be connected to the W-axis 500 of the machine tool.

[0064] A machining center machine tool, as Figures 12 - 14 shown, includes a machine tool body and a cutting tool. A machine tool spindle is arranged on the machine tool body. The machine tool spindle is connected to the tool body 1 through a connecting flange. A connecting main handle 400 is arranged inside the machine tool spindle. The connecting main handle 400 is connected to the W-axis 500 of the machine tool. The W-axis 500 of the machine tool is fixedly connected to the push rod 2. The machine tool spindle drives the cutting tool to rotate, and the W-axis 500 of the machine tool drives the push rod 2 to axially move so as to drive the cutting head 5 to generate a radial displacement, thereby changing the size of the diameter of the circle formed by the rotation of the cutting head 5.

[0065] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
