[0053] A base 7 and a bed body 8 slidably disposed on the base 7 along a first horizontal direction. A rotary table receiving cavity 81 is provided on the bed body 8;

[0054] An arc-shaped slide rail 9 provided on the cavity wall of the receiving cavity of the bed body 8, and a rotating seat 10 rotatably disposed on the arc-shaped slide rail 9. The rotating seat 10 can rotate along the arc-shaped slide rail 9, and the rotation axis of the rotating seat 10 is arranged along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction;

[0055] A rotary table mounting seat 11 slidably disposed on the rotating seat 10 along the second horizontal direction;

[0056] The rotary table 500 is used to fix the turbine disk 12 to be dovetailed. The rotary table 500 can be detachably mounted on the rotary table mounting base 11. The rotary table 500 has a rotatable drive sleeve 501. The drive sleeve 501 is used to pass through the central hole of the turbine disk 12 to be dovetailed to fix the turbine disk 12 to be dovetailed. The rotation axis of the drive sleeve 501 is coaxial with the axis of the central hole of the fixed turbine disk 12.

[0057] The broach assembly fixing mechanism 600 is located on one side of the rotary table accommodating cavity 81 and is used to fix the broach assembly 100 and can drive the fixed broach assembly 100 to move in the vertical direction.

[0058] In the vertical multi-axis CNC dovetail broaching machine provided by the present invention, the machine body 8 is slidably arranged on the base 7 in the first horizontal direction, the rotating seat 10 is rotatably arranged on the arc-shaped slide rail 9 of the machine body 8, the rotary table mounting base 11 is slidably arranged on the rotating seat 10 in the second horizontal direction, the rotary table 500 can be detachably mounted on the rotary table mounting base 11 and has a rotatable drive sleeve 501. The drive sleeve 501 is used to pass through the central hole of the turbine disk 12 to be dovetailed to fix the turbine disk 12 to be dovetailed. The second horizontal direction is perpendicular to the first horizontal direction. The rotation axis of the drive sleeve 501 is perpendicular to the first horizontal direction and the second horizontal direction at the same time. Therefore, the angular position of the turbine disk 12 fixed by the rotary table 500 relative to the broach assembly fixing mechanism 600 can be flexibly adjusted through the multi-directional and multi-angle movements (including moving and rotating) of the machine body 8, the rotating seat 10, the rotary table mounting base 11, and the drive sleeve 501. Thus, the broaching operation of the broach assembly 100 on the turbine disk 12 on the broach assembly fixing mechanism 600 can be efficiently and conveniently realized by this vertical multi-axis CNC dovetail broaching machine. For example, when the drive sleeve 501 rotates one week, the fixed turbine disk 12 can be rotated one week. Each time the angle of a machining position is rotated, the dovetail broaching of the entire week of the turbine disk 12 can be conveniently carried out. When the rotating seat 10 changes the angle, the dovetail broaching angle of the turbine disk 12 can be conveniently adjusted.

The drive sleeve 501 is arranged between the upper limit ring frame 504 and the lower limit plate 503. The drive sleeve 501 is coaxially connected to the output shaft of the first motor 505. When the turbine disc 12 is fixed on the drive sleeve 501, it is limited between the upper limit ring frame 504 and the lower limit plate 503, and when the drive sleeve 501 rotates, it drives the turbine disc 12 to rotate between the upper limit ring frame 504 and the lower limit plate 503. A connecting column 506 is rotatably provided on the lower limit plate 503, and the driving sleeve 501 is hollowly sleeved on the outer circumference side of the connecting column 506, so that the output shaft of the first motor 505 can be directly connected to the driving sleeve 501 through transmission, but the output shaft of the first motor 505 can also be connected to the driving sleeve 501 through transmission through the connecting column 506 (in this case, the driving sleeve 501 is fixedly sleeved on the outer circumference side of the connecting column 506), and a central vertical shaft 507 is connected to the center of the upper limit ring frame 504, and the central vertical shaft 507 is rotatably supported in the central circular groove 508 of the connecting column 506.

When the turntable 500 is installed on the turntable mounting seat 11, the first limiting beam 13 and the second limiting beam 14 can press down the upper limiting ring frame 504, thereby fixing the turntable 500 between the first limiting beam 13 and the second limiting beam 14 and the turntable mounting seat 11.

[0064] According to a specific embodiment of the present application, the vertical multi-axis numerical control tenoning broaching machine includes two first guide rails 16 arranged on the base 7. The two first guide rails 16 are parallel to each other and extend along the first horizontal direction. The machine body 8 is supported on the two first guide rails 16.

[0065] According to a specific embodiment of the present application, the vertical multi-axis numerical control tenoning broaching machine includes an arc-shaped rack 20 connected to the lower part of the rotating seat 10. A second motor 21 is installed on the machine body 8. The output shaft of the second motor 21 is connected with a worm 22. The worm 22 meshes with the arc-shaped rack 20. After starting the second motor 21, the arc-shaped rack 20 is driven to rotate through the worm 22, thereby driving the rotating seat 10 to rotate.

[0066] According to a specific embodiment of the present application, the broach assembly fixing mechanism 600 includes a vertical body 601, a vertical rail 602 disposed on the side of the vertical body 601 facing the bed 8, and a moving member 603 (such as a slider or a fixing plate) slidably disposed vertically on the vertical rail 602. The vertical multi-axis CNC mortising broaching machine further includes a vertical driving device 23 for driving the moving member 603 to slide along the vertical rail 602. The housing of the vertical driving device 23 is connected to a U-shaped frame 604 on the vertical body 601. The vertical driving device 23 may include a lead screw motor with a lead screw threadedly engaged with the moving member 603, or may be a hydraulic cylinder or a pneumatic cylinder. The broach assembly 100 includes a broach box 101 and a broach 102 disposed on the broach box 101. When the broach assembly 100 is installed on the broach assembly fixing mechanism 600, the broach 102 faces the rotary table receiving cavity 81. An insertion hole 103 is provided on the back surface of the broach box 101. A fixing rod 605 is provided on the moving member 603. The fixing rod 605 can be inserted into the insertion hole 103 so that the broach box 101 is hung and fixed on the moving member 603. The insertion hole 103 extends obliquely from the back surface of the broach box 101. Specifically, it can be understood that the insertion hole 103 extends from the back surface of the broach box 101 towards the inside of the broach box 101 in a direction forming an angle with the back surface of the broach box 101. The fixing rod 605 extends obliquely from the moving member 603 corresponding to the extending direction of the insertion hole 103. Since both the insertion hole 103 and the fixing rod 605 are arranged obliquely, when the fixing rod 605 is inserted into the insertion hole 103 and the back surface of the broach box 101 abuts against the moving member 603, the inclined fixing rod 605 can generate a limiting force towards the moving member 603 on the broach box 101 in a direction perpendicular to the back surface of the broach box 101, so that the broach assembly 100 is more firmly hung on the moving member 603.

The moving drive mechanism 300 is movably installed on the guide rail truss 3 to be able to move on the guide rail truss 3 to drive the broach extraction mechanism 400 to any broach storage station among the plurality of broach storage stations, to drive to the broach loading station 11, and to drive to the broach replacement station;

[0071] The broach extraction mechanism 400 is at least used for extracting and installing the broach assembly 100 in an upright state at the broach loading station 11 to the broach storage station and for extracting and fixing the broach assembly 100 stored at the broach storage station.

[0072] During specific operations, the broach extraction mechanism 400 can be moved to the broach storage station, the broach loading station 11, and the broach replacement station as needed. The broach extraction mechanism 400 is at least used to extract and install the broach assembly 100 in an upright state at the broach loading station 11 to the broach storage station, and to extract and fix the broach assembly 100 stored at the broach storage station. The broach replacement station is adjacent to the broach assembly fixing mechanism 600, so that when the broach extraction mechanism 400 extracts the broach assembly 100 and brings it to the broach replacement station, it can be conveniently taken away and installed on the broach assembly fixing mechanism 600 to achieve the initial loading or replacement of the broach assembly 100. Therefore, the device for automatically replacing the broach and the broach box in the vertical multi-axis CNC mortising broaching machine provided by the present invention can mechanize and automate the replacement of the broach assembly 100 through these mechanisms, improving the convenience and efficiency of tool change. When applied to the production line of the disk mortise, it can also prevent human errors caused by manual tool change, thereby improving the machining accuracy of the turbine disk 12. Specifically, the broach assembly 100 extracted by the broach extraction mechanism 400 at the broach replacement station can be installed on the moving member 603 of the broach assembly fixing mechanism 600 through an additional loading mechanism. Since the broach extraction mechanism 400 itself is arranged on the moving drive mechanism 300 so as to be liftable and rotatable about the vertical axis, it is also completely possible to directly drive the broach assembly 100 to be installed on the moving member 603 of the broach assembly fixing mechanism 600 through the movement of the broach extraction mechanism 400. Specifically, it can be achieved by controlling the movement of the broach assembly 100 so that the fixing rod 605 is inserted into the insertion hole 103, and the broach box 101 is hung and fixed on the moving member 603.

[0073] According to a specific embodiment of the present application, the length direction of the broach magazine 2 and the length direction of the guide rail truss 3 are both along the horizontal direction and parallel to each other. A plurality of broach storage stations are arranged at intervals along the length direction of the broach magazine 2. The guide rail truss 3 preferably has two, and the two guide rail trusses 3 are arranged in parallel and are both located above the broach magazine 2, one above the other. A broach fixing frame 4 is provided at each broach storage station on the broach magazine 2. The broach assembly 100 includes a broach box 101 and a broach 102 provided on the broach box 101. The broach 102 can include various types of blades, such as cylindrical tooth-shaped blades or sheet blades, etc. An insertion hole 103 is provided on the back of the broach box 101. An insertion post 41 is provided on the broach fixing frame 4. The insertion post 41 is inserted into the insertion hole 103 so that the broach box 101 is hung and fixed on the broach fixing frame 4. Both the insertion hole 103 and the insertion post 41 are multiple. When the broach box 101 is hung and fixed on the broach fixing frame 4, preferably a plurality of insertion posts 41 are simultaneously inserted into the corresponding insertion holes 103.

[0074] According to a preferred embodiment of the present application, the insertion hole 103 extends obliquely from the back surface of the broach holder 101 towards the inside of the broach holder 101 at an angle with the back surface. The insertion post 41 extends obliquely corresponding to the extension direction of the insertion hole 103 from the broach fixing frame 4. Alternatively, an inclined block 6 can also be installed on the broach fixing frame 4, and the insertion post 41 is arranged on the inclined surface of the inclined block and extends obliquely with respect to the broach fixing frame 4. In this embodiment, since both the insertion hole 103 and the insertion post 41 are arranged obliquely, when the insertion post 41 is inserted into the insertion hole 103 and the back surface of the broach holder 101 abuts against the broach fixing frame 4, the inclined insertion post 41 can generate a limiting force towards the broach fixing frame 4 on the broach holder 101 in the direction perpendicular to the back surface of the broach holder 101, so that the broach assembly 100 is more firmly hung on the broach fixing frame 4. Of course, the specific angular arrangement of the insertion hole 103 and the insertion post 41 is not limited to this embodiment, and even a non-inclined solution will fall within the protection scope of the present invention. At this time, other limiting structures can also be provided to ensure that the broach assembly 100 is more firmly hung on the broach fixing frame 4.

[0075] According to an embodiment of the present application, the insertion hole 103 includes a main hole 104 and a long groove 105 communicated with the upper end of the main hole 104. A boss 108 protrudes from the hole wall of the insertion hole 103, and the boss 108 encloses the long groove 105. The width of the long groove 105 is smaller than the aperture of the main hole 104. The insertion post 41 includes a main column body 411 and a column head 412 located at one end of the main column body 411 away from the broach fixing frame 4. The diameter of the column head 412 is larger than the diameter of the main column body 411. When the insertion post 41 is inserted into the insertion hole 103 in place, the main column body 411 is located in the long groove 105, and the side surface of the column head 412 facing the main column body 411 abuts against the boss 108 to form a limit (or it is also possible that the side surface of the column head 412 facing the main column body 411 does not abut against the boss 108 but only limits the boss 108). Such a hole type design of the insertion hole 103 can also better limit and fix the broach holder 101. Of course, the specific hole type of the insertion hole 103 is not limited to this embodiment.

[0076] According to an embodiment of the present application, a first hanging post 106 is provided on the first side surface of the broach holder 101, and a second hanging post 107 is provided on the second side surface of the broach holder 101 opposite to the first side surface. The broach extraction mechanism 400 includes an extraction mechanism main seat 401 and a first hanging plate 402 and a second hanging plate 403 which are arranged at intervals and connected to the extraction mechanism main seat 401. A first hook 404 for hooking the first hanging post 106 is provided on the first hanging plate 402, and a second hook 405 for hooking the second hanging post 107 is provided on the second hanging plate 403. When the broach extraction mechanism 400 extracts the broach assembly 100, the first hook 404 and the second hook 405 respectively hook the first hanging post 106 and the second hanging post 107 on both sides, so as to firmly hang the broach assembly 100.

[0077] According to a preferred embodiment of the present application, a plurality of first hooks 404 may be arranged vertically, a plurality of second hooks 405 may be arranged vertically, and the number of the first hanging posts 106 and the second hanging posts 107 corresponds to a plurality. When the broach extraction mechanism 400 extracts the broach assembly 100, the plurality of vertically arranged first hooks 404 and second hooks 405 respectively hook the plurality of vertically arranged first hanging posts 106 and second hanging posts 107 on both sides, so as to firmly hook the broach assembly 100.

[0078] According to a preferred embodiment of the present application, the first hanging post 106 extends obliquely away from the first side surface along a direction forming an angle with the first side surface, and the second hanging post 107 extends obliquely away from the second side surface along a direction forming an angle with the second side surface. The inclined design of the first hanging post 106 and the second hanging post 107 is similar to the advantages of the inclined design of the above-mentioned insertion holes 103 and the insertion posts 41, and can also facilitate the first hook 404 and the second hook 405 to more firmly hook the broach assembly 100.

[0079] According to an embodiment of the present application, the broach turning-up tool mechanism 200 includes a turning drive motor 201 and a broach clamping seat 202 connected to the turning drive motor 201. The turning drive motor 201 can be arranged on the ground or other suitable positions. A support column 203 is arranged at the rear side of the broach clamping seat 202. The front side of the broach clamping seat 202 is used for clamping and fixing the broach assembly 100. The broach clamping seat 202 can be driven by the turning drive motor 201 to move between a horizontal position and an upright position. When the broach clamping seat 202 is in the horizontal position, the support column 203 supports downward on the ground, and the broach assembly 100 clamped and fixed on the broach clamping seat 202 is in a horizontal state. When the broach clamping seat 202 is in the upright state, the broach assembly 100 clamped and fixed on the broach clamping seat 202 is in an upright state. Specifically, a first movable clamp and a second movable clamp can be respectively installed at two ends of the broach clamping seat 202 in the length direction. The first movable clamp and the second movable clamp can approach each other to clamp and fix the broach box 101 of the broach assembly 100, or can move away from each other to release the clamping and fixing of the broach box 101 of the broach assembly 100. The first movable clamp includes a clamping beam 204 hinged to the broach clamping seat 202. The first end of the clamping beam 204 is used for contacting the broach box 101 of the broach assembly 100 and cooperating with the second movable clamp to clamp the broach box 101 of the broach assembly 100. A first clamp cylinder 205 is hinged to the second end of the clamping beam 204, and is used for telescoping to drive the second end of the clamping beam 204 to rotate, so that the first end of the clamping beam 204 can approach or move away from the broach box 101 of the broach assembly 100. The second movable clamp can include a second clamp cylinder 206 and a top column 207 connected to the piston rod of the second clamp cylinder 206. The telescoping movement of the second clamp cylinder 206 makes the top column 207 approach or move away from the broach box 101 of the broach assembly 100, so that the top column 207 contacts the broach box 101 of the broach assembly 100 and cooperates with the first end of the clamping beam 204 to clamp the broach box 101 of the broach assembly 100. In addition, a broach box 101 support block 208 can also be installed in the middle of the broach clamping seat 202, and is used for supporting the broach box 101.

[0080] According to specific embodiments of the present application, the broach extraction mechanism 400 includes a lifting drive device 406 (such as a hydraulic cylinder, a pneumatic cylinder, etc.) and a rotation drive device 407 (such as a rotation drive motor, etc.). The extraction mechanism main body seat 401 is connected to the rotation drive device 407. The rotation drive device 407 is rotatably arranged on the lifting drive device 406 around a vertical axis and can drive the extraction mechanism main body seat 401 to drive the first hanging plate 402 and the second hanging plate 403 to rotate around the vertical axis. The lifting drive device 406 is respectively connected to the moving drive mechanism 300 and the rotation drive device 407 to be able to drive the rotation drive device 407 to move up and down relative to the moving drive mechanism 300. After the broach extraction mechanism 400 extracts the broach assembly 100 in an upright state at the broach loading station 11, the extracted broach assembly 100 can pass through the broach extraction mechanism 400 along the guide rail truss 3, and through the combined action of the lifting of the extraction mechanism main body seat 401 and the rotation around the vertical axis, the insertion hole 103 on the broach box 101 is inserted into place by the insertion post 41.

[0081] During the specific operation, the broach clamping seat 202 is first in a horizontal lying state, the broach box 101 of the broach assembly 100 is horizontally installed (in a horizontal state) on the broach clamping seat 202, and the broach 102 thereon is arranged downward, and then the flip drive motor 201 drives the broach clamping seat 202 to rotate 90° from the horizontal lying state to an upright state. At this time, the broach assembly 100 is flipped to an upright state and the broach 102 faces the broach fixing frame 4, and the insertion hole 103 on the broach box 101 faces away from the broach fixing frame 4. At this time, the movement of the broach extraction mechanism 400 (lifting, rotating, and lateral movement along the guide rail truss 3, etc.) makes the first hook 404 and the second hook 405 of the broach extraction mechanism 400 hook the first hanging column 106 and the second hanging column 105 on both sides respectively. The second hanging column 107 extracts the broach assembly 100, and then the broach clamping seat 202 releases the clamping of the broach box 101 of the broach assembly 100, so that the broach extraction mechanism 400 moves along the guide rail truss 3, as well as lifts and rotates around the vertical axis, gradually allowing the column head 412 of the inserted column 41 to enter the main hole 104 first. When the column head 412 has completely passed through the boss 108, the broach box 101 is lowered, and then the main column body 411 gradually enters the long groove 105 until the upper side surface of the boss 108 contacts and supports on the main column body 411, and the side surface of the column head 412 facing one side of the main column body 411 abuts against the boss 108 to limit the boss, and finally until the back of the broach box 101 abuts against the broach fixing frame 4, thereby completing the loading operation of the broach assembly 100. When the broach assembly 100 on the broach fixing frame 4 needs to be taken out, similarly, the broach extraction mechanism 400 can be moved (lifted, rotated, and moved horizontally along the guide rail truss 3, etc.) so that the first hook 404 and the second hook 405 of the broach extraction mechanism 400 respectively hook the first hanging column 106 and the second hanging column 107 on both sides to extract the broach assembly 100, and then the broach extraction mechanism 400 moves along the guide rail truss 3 and rotates around the vertical axis, gradually making the insertion column 41 leave the insertion hole 103 until the broach assembly 100 is completely separated from the broach fixing frame 4 , and then the mobile driving mechanism 300 drives the broach extraction mechanism 400 to move along the guide rail truss 3 to the broach replacement station, and then the broach assembly 100 is taken away and installed on the broach assembly fixing mechanism 600 to realize the initial loading or replacement of the broach assembly 100. According to one embodiment, the broach extraction mechanism 400 can have the function of installing the broach assembly 100 on the broach assembly fixing mechanism 600, or, according to another embodiment, the broach assembly 100 on the broach extraction mechanism 400 can also be installed on the broach assembly fixing mechanism 600 through other additional devices.

[0082] According to one embodiment of the present application, the device for automatically replacing the broach and the broach box includes a linear rack 5 arranged on the frame 1, and the length direction of the linear rack 5 is consistent with the length direction of the guide rail truss 3. The mobile drive mechanism 300 includes a mobile frame 301, a mobile drive motor 302 installed on the mobile frame 301, and a mobile drive gear 303 connected to the output shaft of the mobile drive motor 302. The mobile frame 301 is movably installed on the guide rail truss 3, and the lifting drive device 406 is detachably connected to the mobile frame 301. The mobile drive gear 303 is meshed with the linear rack 5. The broach extraction mechanism 400 is liftable and rotatable around the vertical axis and is arranged on the mobile frame 301. When the mobile drive motor 302 is running, the mobile drive gear 303 rotates, thereby moving along the linear rack 5, so that the mobile frame 301 can be moved along the guide rail truss 3. Of course, the movement mode of the mobile frame 301 is not limited to relying on the gear rack coordination mentioned in this embodiment, and can also be achieved by setting an electric guide rail truss 3 and other devices.

[0083] According to a specific embodiment of the present application, the device for automatically replacing broaches and broach boxes includes a general control unit (such as a computer, etc.), and the broach flipping and knife loading mechanism 200, the moving drive mechanism 300 and the broach extraction mechanism 400 are all connected to the general control unit by signal. Specifically, the electric control ends of the flipping drive motor 201, the moving drive motor 302, the lifting drive device 406, the rotating drive device 407, the first clamp cylinder 205 and the second clamp cylinder 206 are all connected to the general control unit by signal, so that the broach flipping and knife loading mechanism 200, the moving drive mechanism 300 and the broach extraction mechanism 400 can be controlled by the general control unit to operate automatically.

[0084] It should be noted that the above embodiments only express the preferred implementation of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the present application. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, such as combining different features in various embodiments, etc., which should all fall within the scope of protection of the present application.
