[0027] Specifically, when processing a workpiece, the workpiece is first placed on the top of the workbench 6, and then the position of the spindle assembly 2 is adjusted according to the processing requirements, and the second servo motor 302 is started so that the second servo motor 302 drives the spindle assembly 2 as a whole to translate left and right along the X track 301. When the spindle body 202 translates left and right, the horizontal drag chain 203 will move accordingly. Then, according to the required height for processing, the first servo motor 201 is started to drive the spindle body 202 to move up and down. When the height of the spindle body 202 changes, the vertical drag chain 204 also moves accordingly to adapt to the height of the first servo motor 201.

[0028] Please refer to Figure 4 , Figure 6 , Figure 7The adjusting component 7 includes a flipping component 702, and a track component 701 and a clamping component 703 are respectively arranged on both sides of the flipping component 702. A hydraulic push rod 704 is fixedly installed on the top of the flipping component 702. Driven by the output shaft of the hydraulic push rod 704, the flipping component 702 moves up along the track component 701 and cooperates with each other to realize the flipping of the clamping component 703.

[0029] Furthermore, the track assembly 701 includes a track plate 7011, the top of the hydraulic push rod 704 is fixedly connected to the top of the track plate 7011, a rotation groove 7014 is opened on one side of the track plate 7011, a rotation inclined groove 7013 is opened on the top and bottom of the rotation groove 7014, and a vertical track groove 7012 is opened on the side of the rotation inclined groove 7013 away from the rotation groove 7014.

[0030] Furthermore, the flipping assembly 702 includes a moving shaft 7021, a side of the moving shaft 7021 close to the clamping assembly 703 is fixedly connected to a connecting rod 7023, a side of the moving shaft 7021 away from the clamping assembly 703 is fixedly connected to a limiting pad 7022, and the moving shaft 7021 completes the flipping action along the vertical track groove 7012, the rotating groove 7014, and the rotating inclined groove 7013 as the fixed rod 7024 moves upward, the bottom of the connecting rod 7023 is fixedly connected to a side of the clamping assembly 703, the outer side of the round rod 7028 is rotatably connected to the fixed rod 7024, and the top of the fixed rod 7024 is fixedly connected to the output shaft of the hydraulic push rod 704.

[0031] Specifically, the hydraulic push rod 704 is started to drive the fixed rod 7024 to move upward. During the upward movement of the fixed rod 7024, the connecting rod 7023 is pushed to rise along the bottom vertical track groove 7012, the bottom rotating bevel groove 7013, the rotating groove 7014, the top rotating bevel groove 7013 and the top vertical track groove 7012 in sequence. Among them, the width of the connecting rod 7023 and the outer diameter of the limiting pad 7022 are both larger than the outer diameter of the moving shaft 7021, and the length of the moving shaft 7021 is the same as the thickness of the vertical track groove 7012, the rotating bevel groove 7013 and the rotating groove 7014. Therefore, the moving shaft 7021 is limited in the vertical track groove 7012, the rotating bevel groove 7013 and the rotating groove 7014. 7013, the inner side of the rotating groove 7014, the upward movement process can only move along the vertical track groove 7012, the rotating bevel groove 7013, and the rotating groove 7014 path. When the moving shaft 7021 moves to the connection between the bottom vertical track groove 7012 and the rotating bevel groove 7013, the workpiece clamped by the clamping assembly 703 rises to a certain height, and the moving shaft 7021 continues to move obliquely along the rotating bevel groove 7013, driving the round rod 7028 to rotate, and when it continues to move to the midpoint of the rotating groove 7014, it completes a 90-degree flip, and then continues to move upward until it completely passes through the top rotating bevel groove 7013, at this time completing a 180-degree flip.

[0032] Furthermore, the flip assembly 702 also includes a mounting block 7025, which is fixedly connected to the side of the round rod 7028 away from the connecting rod 7023. The mounting block 7025 is provided with a convex limiting groove 7026 on the front and back sides of the side close to the clamping assembly 703, and an electric push rod 7027 is fixedly installed on the inner wall of the convex limiting groove 7026.

[0033] Specifically, since the round rod 7028 is fixedly connected to the mounting block 7025, when the round rod 7028 rotates, the mounting block 7025 is driven to rotate, thereby driving the workpiece clamped by the clamping assembly 703 to rotate together.

[0034] Furthermore, the clamping assembly 703 includes an L-shaped clamp block 7031, one end of the L-shaped clamp block 7031 close to the mounting block 7025 is fixedly connected to a limiting block 7032, the adjacent sides of the two L-shaped clamp blocks 7031 are fixedly connected to an anti-slip strip 7033, and the output shaft of the electric push rod 7027 is fixedly connected to the limiting block 7032.

[0035] Specifically, the clamping assembly 703 performs stable clamping according to the width of the workpiece, and the output shaft of the electric push rod 7027 is extended or shortened to push or pull back the limit block 7032, thereby changing the distance between two adjacent L-shaped clamping blocks 7031, and the size of the convex limit groove 7026 close to the output shaft of the electric push rod 7027 is matched with the size clearance of the limit block 7032 to ensure that the limit block 7032 can move normally, and the size of the convex limit groove 7026 away from the output shaft of the electric push rod 7027 is matched with the size clearance of the L-shaped clamping block 7031 to ensure that the limit block 7032 is limited when it moves to the maximum distance between the two L-shaped clamping blocks 7031, so as to adapt to workpieces of different widths.

[0036] Please refer to Figure 4 , Figure 5 The workbench 6 includes a table body 601, the bottom of the track plate 7011 is fixedly connected to the two sides of the top of the table body 601, a heat dissipation groove 602 is provided on the top of the table body 601, the Y-axis guide assembly 4 includes a Y track 401 and a third servo motor 402, the output shaft of the third servo motor 402 is fixedly connected with a lead screw, the bottom of the table body 601 is provided with a mounting hole that matches the thread of the lead screw of the third servo motor 402, the two sides of the bottom of the table body 601 are slidably connected to the top of the Y track 401, and a cleaning assembly 8 for scraping off debris is provided on the top of the workbench 6.

[0037] The platform 601 is movably connected to the lead screw of the third servo motor 402 . The third servo motor 402 is installed on the top of the front side of the frame 1 and located at the bottom of the platform 601 .

[0038] Specifically, the third servo motor 402 is started to drive the workbench 6 to move forward and backward along the Y track 401 to adjust the processing position of the top of the workpiece in the front and back directions accordingly. After the processing is completed, the cleaning component 8 is used to move back and forth on the top of the workbench 6 to clean the workbench 6.

[0039] Please refer to Figure 4 , Figure 5 , Figure 8 The cleaning component 8 includes a cleaning shovel 805 and a cleaning block 803. The outer size and shape of the cleaning block 803 are matched with the clearance of the heat dissipation groove 602. A connecting rod 804 is fixedly connected between two adjacent cleaning blocks 803. The top of the cleaning block 803 is fixedly connected with a mounting frame 801. The front and back sides of both sides of the mounting frame 801 are fixedly connected to the cleaning shovel 805. One side of the cleaning shovel 805 is provided with an oblique angle. The side wall of the heat dissipation groove 602 is provided with a movable hole 603 that matches the tolerance of the connecting rod 804. The top of the mounting frame 801 is fixedly connected with a handle 802.

[0040] Specifically, after the processing is completed, hold the two handles 802 on the front and back sides, use the cleaning shovel 805 to shovel back and forth on the top of the workbench 6 to clean the top of the table body 601, and move the cleaning block 803 back and forth in the heat dissipation groove 602 to clean the debris inside the heat dissipation groove 602.

[0041] Specifically, the bottom of the track plate 7011 is fixedly connected to both sides of the top of the platform 601, and the width of the cleaning shovel 805 is the same as the thickness of the track plate 7011. Figure 4 As shown, when the cleaning assembly 8 is located on one side of the platform 601, the cleaning shovel 805 can just bypass the track plate 7011 and clean the platform 601 located on the front and back sides of the track plate 7011. When the output shaft of the hydraulic push rod 704 is in the longest state, that is, as shown in FIG. Figure 4 As shown, at this time, the fixing rod 7024 and the clamping assembly 703 are both in the initial state, and the thickness of the mounting frame 801 and the cleaning shovel 805 are the same as the distance from the bottom of the fixing rod 7024 to the top of the table 601 at this time, ensuring that the cleaning assembly 8 can still move normally on the table 601 in the initial state, and the cleaning shovel 805 can completely shovel the debris on the top of the table 601 to the outside, and the cleaning block 803 completely fits the shape of the heat sink 602, and can also push out the debris inside the heat sink 602.

[0042] Please refer to Figure 1 A tool magazine 5 is installed on one side of the frame 1, and the tool magazine 5 is used to store cutting tools used for processing.

[0043] How it works When processing a workpiece, the workpiece is first placed on the top of the workbench 6, and the clamping assembly 703 clamps the workpiece stably according to the width of the workpiece. The output shaft of the electric push rod 7027 extends or shortens to push or pull back the limit block 7032, thereby changing the distance between two adjacent L-shaped clamping blocks 7031 to adapt to the width of the workpiece to be processed, so as to stably clamp the workpiece; Then, the position of the spindle assembly 2 is adjusted according to the processing requirements, and the second servo motor 302 is started to drive the second servo motor 302 screw rod to rotate. The spindle bracket moves with the second servo motor 302 screw rod and translates left and right along the X track 301 under the limit of the X track 301. When the spindle body 202 translates left and right, the horizontal drag chain 203 will move accordingly. Then, according to the required height for processing, the first servo motor 201 is started to drive the first servo motor 201 screw rod to rotate, so that the spindle body 202 moves up and down under the limit of the spindle bracket and the drive of the first servo motor 201 screw rod. When the height of the spindle body 202 changes, the vertical drag chain 204 also moves accordingly to adapt to the height of the first servo motor 201, and the third servo motor 402 is started to drive the third servo motor 402 screw rod to rotate. The workbench 6 moves forward and backward along the Y track 401 under the drive of the third servo motor 402 screw rod to adjust the processing position of the top of the workpiece in the front and back direction accordingly. When the bottom of the workpiece needs to be processed, the hydraulic push rod 704 is started to drive the fixed rod 7024 to move upward. During the upward movement of the fixed rod 7024, the connecting rod 7023 is pushed to rise along the bottom vertical track groove 7012, the bottom rotating bevel groove 7013, the rotating groove 7014, the top rotating bevel groove 7013 and the top vertical track groove 7012 in sequence. When the moving shaft 7021 moves to the connection between the bottom vertical track groove 7012 and the rotating bevel groove 7013, the workpiece clamped by the clamping assembly 703 rises to a certain height, and the moving shaft 7021 continues to move obliquely along the rotating bevel groove 7013, driving the round rod 7028 to rotate. When it continues to move to the midpoint of the rotating groove 7014, it just completes a ninety-degree flip, and then continues to move upward until it completely passes through the top rotating bevel groove 7013. At this time, the flip action of 180 degrees is completed, and the bottom of the workpiece is processed; After the processing is completed, hold the two handles 802 on the front and back sides, use the cleaning shovel 805 to shovel back and forth on the top of the workbench 6 to clean the top of the table body 601, and move the cleaning block 803 back and forth in the heat dissipation groove 602 to clean the debris inside the heat dissipation groove 602.

[0044] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
