It integrates multiple metal cutting processing technologies such as turning, milling and drilling, and uses CNC technology to accurately control the processing process. Among them, CNC machine tools are mainly divided into vertical CNC lathes with vertical spindle boxes and horizontal lathes with horizontal spindle boxes according to different structural layouts.

[0003] At present, although CNC vertical lathes use CNC technology to accurately control the processing process and have a variety of metal cutting processes such as turning, milling, and drilling, due to the vertical arrangement of the spindle box of the vertical lathe, it is inconvenient to perform fine processing on the side of the metal workpiece. When processing complex workpieces, they need to be used in combination with horizontal lathes. Although the vertical and horizontal combined CNC lathes meet the processing needs of complex workpieces, they have the problems of large space occupation and high construction cost.

[0010] By adopting the above technical solution, the fixed seats are fixedly connected to the fixed seats, and are rotationally connected to the connecting seats through the rotating shaft. When the cylinder is started, the connecting seat can be driven to move in the vertical direction through the translation seat. During this process, the mounting seat is allowed to rotate. The slide rail is mainly used to limit the translation seat so that it can only move vertically in the up and down directions, and ensure the stability of the translation seat when moving.

[0014] By adopting the above technical solution, the distance between the two side plates is not less than the width of the mounting seat, so the mounting seat will not be interfered by the side plates during movement. When the mounting seat moves downward from the upper horizontal state to the vertical state, the sliding column will be at the lowest point inside the inclined groove, forming a pulling force.

[0019] Preferably, a circular opening is opened near the upper part of the front surface of the sleeve shell, a circular seat is fixedly installed at the center of the front surface of the gear seat, a storage seat is installed on the front surface of the circular seat, and the spindle box is fixedly installed on the front surface of the storage seat.

[0020] By adopting the above technical solution, the circular opening is mainly used to avoid the circular seat, and the storage seat and the circular seat are connected, which is mainly used for installing the spindle box.

[0021] Preferably, the front surface of the circular seat is fixedly connected to an outwardly extending extension frame near the edge, the front surface of the extension frame is fixedly connected to a mounting shaft, the outer surface of the mounting shaft is rotatably connected to a trigger wheel, and the front surface of the shell is provided with a plurality of limit switches installed at a position outside the circular opening, and the plurality of limit switches are circumferentially distributed on the outside of the circular seat and cooperate with the trigger wheel.

[0022] By adopting the above technical solution, the number of limit switches is set to , and they are distributed in a circle on the surface of the shell near the circular opening, and the lever faces inward. The trigger wheel is rotatably connected to the extension frame through the mounting shaft, and the extension frame is fixedly connected to the circular seat. Therefore, when the circular seat and the spindle box rotate, the trigger wheel will trigger the limit switch once every 10° rotation.

[0023] Preferably, the two arc-shaped platforms are symmetrically fixedly connected to the front surface of the mounting seat, and the front surface of the arc-shaped platform is rollingly connected with a plurality of balls at equal intervals, and the outer surface of the balls is in contact with the rear surface of the storage seat.

[0024] By adopting the above technical solution, the arc table is mainly used to support the storage seat to ensure the stability of the rotation adjustment of the storage seat. By setting the ball bearings, the sliding friction between the arc table and the storage seat can be converted into rolling friction, thereby reducing friction damage and resistance.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention can adjust the spindle box in the vertical lathe from a vertical state to a horizontal state by cooperating with the frame assembly and the adjustment assembly, and has high firmness and a simple and novel overall structure, so that the traditional vertical lathe does not need to be coordinated with the horizontal lathe to perform fine processing on the side of the metal workpiece, which meets the processing needs of complex workpieces without increasing the floor space, and has a low cost, and will not cause additional economic burden to users.

[0027] 2. When the present invention is used, when processing a workpiece, the servo motor can be started as needed to drive the driving gear to rotate. At this time, the driving gear will drive the gear seat to rotate, so that the orientation of the spindle box connected to the surface of the gear seat through the circular seat and the storage seat changes, thereby processing more complex metal workpieces and improving the use effect of the CNC vertical lathe.

[0028] 3. When the present invention is used, during the process of adjusting the direction of the spindle box driven by the servo motor, the trigger wheel connected to the circular seat through the extension frame and the mounting shaft will rotate synchronously, and the limit switch will be triggered every 10° rotation. When the spindle box is adjusted to rotate, the CNC lathe host starts the limit switches on both sides of the specified position in advance. When the spindle box rotates to the specified position, only one of the two open limit switches will be triggered. When both are triggered or neither is triggered, the CNC host will determine that the rotation degree deviation of the spindle box is too large and stop the equipment, effectively avoiding the scrapping of workpieces or even safety hazards after equipment failure.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 9 As shown, the present invention provides a technical solution: a CNC vertical turning, milling and drilling compound cutting device, comprising a frame assembly 1, a frame assembly 2 is arranged on the front side of the frame assembly 1, an adjustment assembly 3 is arranged inside the frame assembly 2, a steering assembly 4 is arranged on the front side of the adjustment assembly 3, the frame assembly 1 comprises an X-axis slide 101 and a spindle box 105, the frame assembly 2 comprises a flat plate 201, side plates 202 are fixedly connected to the outer surfaces of both sides of the flat plate 201, oblique grooves 203 are opened near the top of the outer surfaces of the two side plates 202, and the flat plate 201 is A cylinder 206 is fixedly installed near the bottom of the front surface and the telescopic end of the cylinder 206 is facing upward. The adjustment component 3 is used to cooperate with the frame component 2 to adjust the orientation of the spindle box 105, including a mounting seat 301. The rear surface of the mounting seat 301 is symmetrically fixedly connected with fixed blocks 302 near the upper sides. The outer surfaces of the opposite sides of the two fixed blocks 302 are fixedly connected with sliding columns 303. The outer surface of the sliding column 303 and the inner surface wall of the oblique groove 203 are slidably fitted. The steering assembly 4 includes a housing 401, a servo motor 405 and two arc-shaped tables 406.

[0041] A Y-axis slide 102 is installed on the top of the X-axis slide 101, and a Z-axis slide 103 is installed on the top of the Y-axis slide 102. A slide 104 is provided on the front surface of the Z-axis slide 103. The front surface of the slide 104 is fixedly connected to the rear surface of the flat plate 201. The X-axis slide 101 can control the Y-axis slide 102 to achieve left and right horizontal movement by driving the screw rod. The Y-axis slide 102 can control the Z-axis slide 103 to move horizontally forward and backward by driving the screw rod. The Z-axis slide 103 can control the slide 104 to move vertically up and down by driving the screw rod, thereby driving the spindle box 105 to move within a certain range of space, and cooperating with the external processing table to complete metal processing on the workpiece.

[0042] A fixed seat 304 is installed near the middle of the rear surface of the mounting seat 301, and a rotating shaft 305 is fixedly connected between the inner surface walls of the fixed seat 304, and the outer surface of the rotating shaft 305 is rotatably connected to a connecting seat 306 through a bearing. The connecting seat 306 is located at the rear side of the fixed seat 304, and the rear surface of the connecting seat 306 is fixedly connected to a translation seat 307, the bottom of the translation seat 307 is fixedly connected to the telescopic end of the cylinder 206, the translation seat 307 and the slide rail 205 are slidably connected, the fixed seat 304 is fixedly connected to the fixed seat 304, and is rotatably connected to the connecting seat 306 through the rotating shaft 305. When the cylinder 206 is started, the connecting seat 306 can be driven to move in the vertical direction through the translation seat 307. During this process, the mounting seat 301 is allowed to rotate, and the slide rail 205 is mainly used to limit the translation seat 307, so that it can only perform vertical movement in the up and down directions, and to ensure the stability of the translation seat 307 when moving.

[0043] The vertical distance between the highest and lowest points of the oblique groove 203 is equal to the vertical distance between the center of the slide column 303 and the center of the rotating shaft 305. The fixed block 302 is located outside the connecting seat 306. The top of the connecting seat 306 and the top of the translation seat 307 are in the same plane. The oblique groove 203 is inclined at 45 degrees. The center of the slide column 303 and the center of the rotating shaft 305 are in the same vertical line. A reinforcing plate 308 is fixedly connected between the front surface of the translation seat 307 and the bottom of the connecting seat 306. When the cylinder 206 moves upward, When the translation seat 307 is pushed, the connection seat 306, the rotating shaft 305 and the fixed seat 304 cooperate to generate an upward thrust on the mounting seat 301, and the sliding column 303 will limit the movement trajectory of the mounting seat 301 when sliding inside the oblique groove 203. During the entire movement process, the vertical mounting seat 301 will gradually tilt when moving upward until it moves to the top of the flat plate 201 and forms a horizontal state. During this movement process, the sliding column 303 moves from the lowest point inside the oblique groove 203 to the highest point. The initial distance between the sliding column 303 and the rotating shaft 305 is equal, so that when the mounting seat 301 moves to the uppermost position to form a horizontal state, the centers of the rotating shaft 305 and the sliding column 303 are located on the same horizontal straight line, and in the initial state, the distances between the centers of the rotating shaft 305 and the sliding column 303 and the surface of the mounting seat 301 are equal. Therefore, after the state transformation of the mounting seat 301 is completed, the connecting seat 306 and the mounting seat 301 will be in a parallel state, and the fixing seat 304 will be transformed from a horizontal state to a vertical state, thereby The mounting seat 301 generates a vertical upward supporting force. At the same time, the distance between the sliding column 303 in the initial position and the mounting seat 301 is equal to the distance between the sliding column 303 and the top surface of the plate 201 after adjustment. Therefore, after the position adjustment of the mounting seat 301 is completed, the bottom will be supported by the fixed block 302, the plate 201, and the fixed seat 304 at the same time, thereby maintaining excellent stability and ensuring the stability of the spindle box 105 during operation. The reinforcing plate 308 is used to improve the firmness between the connecting seat 306 and the translation seat 307.

[0044] The outer surfaces of the opposite sides of the two side panels 202 do not fit the outer surfaces of the two sides of the mounting seat 301. An L-shaped plate 204 is fixedly installed between the bottom of the flat plate 201 and the front surfaces of the two side panels 202. The front surface of the L-shaped plate 204 near the top is in conflict with the rear surface of the mounting seat 301 near the bottom. The spacing between the two side panels 202 is not less than the width of the mounting seat 301. Therefore, the mounting seat 301 will not be interfered by the side panels 202 during movement. When the mounting seat 301 moves downward from the horizontal state at the top to the vertical state, the sliding column 303 will be at the lowest point inside the oblique groove 203, forming a pulling force. At the same time, the position of the mounting seat 301 near the bottom will conflict with the L-shaped plate 204, thereby ensuring the stability of the spindle box 105 when the mounting seat 301 is in the vertical state.

[0045] In this embodiment, when the device is used to process a metal workpiece, the X-axis slide 101, the Y-axis slide 102, the Z-axis slide 103, the slide seat 104 and the external processing table cooperate to drive the vertically downward spindle box 105 to perform milling, drilling and fine cutting on the top surface of the workpiece. When it is necessary to perform fine processing on the side of the metal workpiece, the cylinder 206 is started to push the translation seat 307 upward to move. During this process, the connecting seat 306 and the fixed seat 304 rotate through the rotating shaft 305, and at the same time, the mounting seat 301 is pushed upward. When the mounting seat 301 moves upward, the sliding column 303 on the surface of the fixed block 302 slides inside the oblique groove 203, so that the mounting seat 30 1 moves up and flips backward. When the cylinder 206 moves to the maximum stroke, the mounting seat 301 will be in a completely horizontal state, and the bottom will be supported by the flat plate 201, the fixing block 302 and the fixing seat 304 at the same time, so it has good stability. At this time, the spindle box 105 will be transformed from a vertical state to a horizontal state, so that the side of the workpiece can be finely processed in cooperation with the X-axis slide 101, the Y-axis slide 102, the Z-axis slide 103 and the slide 104. The design structure is simple and novel, so that the traditional vertical lathe can perform fine processing on the side of the metal workpiece, which meets the processing needs of complex workpieces without increasing the floor space, and the cost is low, which will not cause additional economic burden to users.

[0046] Embodiment 2: Figure 1-Figure 4 and Figure 6-Figure 8 As shown, the casing 401 is fixedly connected to the front surface of the mounting base 301, and the servo motor 405 is fixedly installed on the rear surface of the mounting base 301 near the bottom. The output end of the servo motor 405 rotates through the rear surface of the mounting base 301 and extends to the front side. The casing 401 is mainly used to protect the driving gear 403 and the gear seat 404, and the servo motor 405 is mainly used to provide rotational driving force for the driving gear 403.

[0047] The output end of the servo motor 405 is fixedly connected to a driving gear 403, and the outer surface of the driving gear 403 is meshingly connected to a gear seat 404 near the top. The driving gear 403 and the gear seat 404 are both arranged inside the sleeve 401 and are rotatably connected to the front surface of the mounting seat 301. Since the driving gear 403 and the gear seat 404 are meshingly connected, the driving gear 403 can drive the gear seat 404 to rotate when it rotates, thereby changing the orientation of the spindle box 105, so that the tool driven by the spindle box 105 can change the cutting angle, so that the vertical lathe can further improve the processing effect.

[0048] A circular opening 402 is provided on the front surface of the sleeve 401 near the upper part, a circular seat 408 is fixedly installed at the center of the front surface of the gear seat 404, a storage seat 409 is installed on the front surface of the circular seat 408, and the spindle box 105 is fixedly installed on the front surface of the storage seat 409. The circular opening 402 is mainly used to avoid the circular seat 408. The storage seat 409 and the circular seat 408 are connected, and are mainly used to install the spindle box 105.

[0049] In this embodiment, when processing the workpiece, the servo motor 405 can be started as needed to drive the driving gear 403 to rotate. At this time, the driving gear 403 will drive the gear seat 404 to rotate, so that the orientation of the spindle box 105 connected to the surface of the gear seat 404 through the circular seat 408 and the storage seat 409 changes, thereby processing more complex metal workpieces and improving the use effect of the CNC vertical lathe.

[0050] Embodiment 3: Figure 8 and Fig. 9 As shown, the front surface of the circular seat 408 is fixedly connected to an outwardly extending extension frame 410 near the edge, the front surface of the extension frame 410 is fixedly connected to a mounting shaft 411, the outer surface of the mounting shaft 411 is rotatably connected to a trigger wheel 412, and the front surface of the casing 401 is located outside the circular opening 402. A plurality of limit switches 413 are installed at a position, which is circumferentially distributed on the outside of the circular seat 408 and cooperates with the trigger wheel 412. The number of limit switches 413 is set to 36, and is circumferentially distributed on the surface of the casing 401 near the circular opening 402, and the lever faces inward, and the trigger wheel 412 rotates with the extension frame 410 through the mounting shaft 411. The extension frame 410 is fixedly connected to the circular seat 408, so when the circular seat 408 and the spindle box 105 rotate, the trigger wheel 412 will trigger the limit switch 413 every time it rotates 10°. When the spindle box 105 needs to be adjusted for rotation, the CNC lathe host starts the limit switches 413 on both sides of the specified position in advance. When the spindle box 105 rotates to the specified position, only one of the two open limit switches 413 will be triggered. When both are triggered or neither is triggered, the CNC host will determine that the rotation degree deviation of the spindle box 105 is too large and stop the equipment, effectively avoiding the scrapping of workpieces or even safety hazards after equipment failure.

[0051] Two arc-shaped platforms 406 are symmetrically fixedly connected to the front surface of the mounting seat 301. The front surface of the arc-shaped platform 406 is equidistantly rollingly connected with a plurality of balls 407. The outer surface of the balls 407 fits the rear surface of the storage seat 409. The arc-shaped platform 406 is mainly used to support the storage seat 409 to ensure the stability of the rotation adjustment of the storage seat 409. By setting the balls 407, the sliding friction between the arc-shaped platform 406 and the storage seat 409 can be converted into rolling friction, thereby reducing friction damage and resistance.

[0052] In this embodiment, when the servo motor 405 drives the spindle box 105 to adjust its direction, the trigger wheel 412 connected to the circular seat 408 through the extension frame 410 and the mounting shaft 411 will rotate synchronously, and the limit switch 413 will be triggered every 10° rotation. When the spindle box 105 is adjusted to rotate, the CNC lathe host starts the limit switches 413 on both sides of the specified position in advance. When the spindle box 105 rotates to the specified position, only one of the two open limit switches 413 will be triggered. When both are triggered or neither is triggered, the CNC host will determine that the rotation degree deviation of the spindle box 105 is too large and stop the equipment, effectively avoiding the scrapping of workpieces or even safety hazards after equipment failure.

[0053] The effect and working principle of the whole mechanism are as follows: when the device is used to process a metal workpiece, the X-axis slide 101, the Y-axis slide 102, the Z-axis slide 103, the slide seat 104 and the peripheral processing table cooperate to drive the vertically downward spindle box 105 to perform fine milling and drilling on the top surface of the workpiece. When fine processing is required on the side of the metal workpiece, the cylinder 206 is started to push the translation seat 307 upward to move. In this process, the connecting seat 306 and the fixed seat 304 rotate through the rotating shaft 305, and at the same time, the mounting seat 301 is pushed upward. When the mounting seat 301 moves upward, the surface of the fixed block 302 The slide column 303 will slide inside the inclined groove 203, so that the mounting seat 301 moves up and flips backward. When the cylinder 206 moves to the maximum stroke, the mounting seat 301 will be in a completely horizontal state, and the bottom is supported by the flat plate 201, the fixing block 302 and the fixing seat 304 at the same time, and has good stability. At this time, the spindle box 105 will be transformed from a vertical state to a horizontal state, so that the side of the workpiece can be finely processed in conjunction with the X-axis slide 101, the Y-axis slide 102, the Z-axis slide 103 and the slide 104. The design structure is simple and novel, so that the traditional vertical lathe does not need to cooperate with the horizontal lathe to process the side of the metal workpiece The surface can be finely processed to meet the processing needs of complex workpieces without increasing the occupied space, and the cost is low, which will not cause additional economic burden to users. In addition, when processing the workpiece, the servo motor 405 can be started to drive the driving gear 403 to rotate as needed. At this time, the driving gear 403 will drive the gear seat 404 to rotate, so that the direction of the spindle box 105 connected to the surface of the gear seat 404 through the circular seat 408 and the storage seat 409 changes, thereby processing more complex metal workpieces, improving the use effect of the CNC vertical lathe, and at the same time, the servo motor 405 drives the spindle box 105 to adjust During the process of adjusting the direction, the trigger wheel 412 connected to the circular seat 408 through the extension frame 410 and the installation shaft 411 will rotate synchronously, and the limit switch 413 will be triggered every 10° rotation. When the spindle box 105 is adjusted to rotate, the CNC lathe host starts the limit switches 413 on both sides of the specified position in advance. When the spindle box 105 is rotated to the specified position, only one of the two open limit switches 413 will be triggered. When both are triggered or neither is triggered, the CNC host will determine that the rotation degree deviation of the spindle box 105 is too large and stop the equipment, effectively avoiding the scrapping of workpieces or even safety hazards after equipment failure.
