[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Refer to Figure 11 as shown in Figure 11 Schematic structural view of the workpiece to be processed;

[0032] A cutting device for a steering gear sleeve, as Figures 1-3 shown, includes a frame, a calibration mechanism 2, a rotating main shaft mechanism 3, a driven auxiliary shaft mechanism 4, a cutting mechanism 5 and a blanking mechanism 6. The frame 1 includes a first mounting bracket 11 and a second mounting bracket 12, and a processing area 13 is formed between the first mounting bracket 11 and the second mounting bracket 12; the above - mentioned mechanisms are all arranged on the first mounting bracket 11 and the second mounting bracket 12, and the workpiece to be processed is cut in the processing area 13.

[0033] As Figures 4-5As shown, the calibration mechanism 2 is used to position the workpiece to be processed, ensuring that the position of the workpiece to be processed placed each time is at the same position. Specifically, the calibration mechanism 2 is arranged on the first mounting bracket 11 and includes a horizontally arranged bottom plate 21, a fixed block 22, an adjustment block 23, a calibration plate 24, and a first actuator 25. The fixed block 22 and the adjustment block 23 are oppositely arranged on the bottom plate 21, and inclined surfaces are arranged on the opposite surfaces. A V-shaped cavity 26 for accommodating the workpiece to be processed is formed by combining the fixed block 22, the adjustment block 23, and the bottom plate 21. The workpiece to be processed is placed in the V-shaped cavity 26, and the two inclined surfaces are respectively tangent to the outer wall of the workpiece to be processed. The calibration plate 24 is arranged at the end of the V-shaped cavity 26, and a calibration inclined surface 261 and a calibration straight surface 262 are arranged on the surface of the calibration plate 24 facing the V-shaped cavity 26. The first actuator 25 can be a cylinder, and the calibration plate 24 is driven to move up and down by the cylinder, that is, the horizontal position of the workpiece to be processed is adjusted. When the workpiece to be processed is placed, it can protrude slightly from the V-shaped cavity 26. By controlling the air intake of the cylinder, the cylinder slowly drives the calibration plate 24 to move up. The workpiece to be processed first contacts the calibration inclined surface 261, and with its own weight, drives the workpiece to be processed to move horizontally until it contacts the calibration straight surface 262. During this process, the workpiece to be processed and the V-shaped cavity 26 are in line contact, thereby greatly reducing the friction between the workpiece to be processed and the V-shaped cavity 26. In addition, the adjustment block 23 can move horizontally, thereby adjusting the distance between the fixed block 22 and the adjustment block 23. Specifically, waist-shaped holes 231 are arranged in parallel on the adjustment block 23, and screws pass through the waist-shaped holes to fix the adjustment block 23 to the bottom plate 21. Preferably, calibration plates 24 are also arranged at the other end of the V-shaped cavity 26, and the side with the calibration inclined surface 261 faces the V-shaped cavity 26, and the distance between the two calibration straight surfaces 262 is equal to the length of the workpiece to be processed.

[0034] As Figures 1-3 and Figure 6 shown, the rotary spindle mechanism 3 is arranged on the first mounting bracket 11. The rotary spindle mechanism 3 includes a motor 31 and a first inner lining jaw 32. The motor 31 drives the first inner lining jaw 32 to rotate through a rotary joint. The first inner lining jaw 32 is inserted into the workpiece to be processed and expands outward to realize the clamping of the workpiece to be processed. Usually, the first inner lining jaw 32 is a jaw cylinder.

[0035] As Figures 1-3 and Figure 7As shown, the driven secondary shaft mechanism 4 is arranged on the second mounting bracket 12. The driven secondary shaft mechanism 4 includes a second inner lining jaw 41 and a first driving mechanism. The second inner lining jaw 41 is rotatably arranged on the first driving mechanism 42 through a rotary joint. The workpiece to be processed on the calibration mechanism 2 is moved to the rotary main shaft mechanism 3 by the first driving mechanism, and the first inner lining jaw 32 and the second inner lining jaw 41 clamp the workpiece to be processed simultaneously. The first inner lining jaw 31 is driven to rotate by the click 31, driving the second inner lining jaw 41 to rotate synchronously. Among them, the first driving mechanism includes a first servo motor 422, a first guide rod 423, a first lead screw 424, a first slider 425, a second servo motor 426, a second guide rod 427, a second lead screw 428 and a second slider 429. The first guide rod 423 is arranged in parallel with the first lead screw 424. The first slider 425 is arranged on the first guide rod 423 and the first lead screw 424. The first lead screw 424 is driven to rotate by the first servo motor 422, so that the first slider 425 moves along the guiding direction of the first guide rod 423, that is, moves towards the first mounting bracket 11. The second guide rod 427 and the second lead screw 428 are arranged in parallel on the first slider 425 and are perpendicular to the first guide rod 423. The second slider 429 is arranged on the second guide rod 427 and the second lead screw 428. The second lead screw 428 is driven to rotate by the second servo motor 426, so that the second slider 429 moves between the calibration mechanism 2 and the rotary main shaft mechanism 3.

[0036] As Figures 1-3 and Figure 8As shown, the cutting device 5 cuts the rotating workpiece to be processed. The cutting device 5 feeds the cutting tool and cooperates with the rotating workpiece to be processed to complete the cutting of the workpiece. The cutting device 5 includes a tool holder 51, a cutting blade 52, and a second driving mechanism 53. The cutting blade 52 is installed on the tool holder 51, and the tool holder 51 is arranged on the second driving mechanism 53. The second driving mechanism 53 drives the cutting blade 52 to move horizontally between the first mounting bracket 11 and the second mounting bracket 12 and move towards the rotary spindle mechanism 3. Among them, the second driving mechanism includes a third servo motor 531, a third guide rod 532, a third lead screw 533, a third slider 534, a fourth servo motor 535, a fourth guide rod 536, a fourth lead screw 537, and a fourth slider 538. The third guide rod 532 is arranged in parallel with the third lead screw 533. The third slider 534 is arranged on the third guide rod 532 and the third lead screw 533. The third servo motor 531 is used to drive the third lead screw 533 to rotate, so that the third slider 534 moves horizontally along the third guide rod 532, that is, the cutting blade 52 moves horizontally between the first processing areas 13. The fourth guide rod 536 and the fourth lead screw 537 are arranged in parallel on the third slider 534 and are perpendicular to the third guide rod 532. The fourth slider 538 is arranged on the fourth guide rod 536 and the fourth lead screw 537. The fourth servo motor 535 is used to drive the fourth lead screw 537 to rotate, so that the fourth slider 538 moves horizontally along the fourth guide rod 537, that is, the cutting blade 52 is driven to move towards the rotary spindle mechanism 3, and the feeding of the cutting blade 52 is realized.

[0037] As Figures 1-5 shown, the blanking mechanism 6 unloads the cut workpiece. After the workpiece is cut, it forms independent individuals, and the blanking mechanism 6 is required to remove the workpiece from the first inner lining jaw 32 and the second inner lining jaw 41. Specifically, the blanking mechanism 6 includes a first air cylinder 61, a second air cylinder 62, a mounting plate 63, and a first jaw cylinder 64 arranged horizontally on the mounting plate 63. The first air cylinder 61 is arranged on the first mounting bracket 11, and the second air cylinder 62 is arranged on the first air cylinder 61. The first air cylinder 61 drives the second air cylinder 62 to move towards the rotary spindle mechanism 3. The mounting plate 63 is arranged on the second air cylinder 62. The second air cylinder 62 is used to drive the mounting plate 63 to move horizontally within the processing area 13, and the workpiece is grabbed by the first jaw cylinder 64. The number of the first jaw cylinders 64 corresponds to the number of the cut workpieces. Specifically, when the workpiece is cut, the first air cylinder 61 drives the first jaw cylinder 64 to move to the position of the workpiece, the workpiece is clamped by the first jaw cylinder 64, and then the slave countershaft mechanism 4 is separated from the workpiece. Then, the second air cylinder 62 drives the workpiece to be separated from the first inner lining jaw 32. Then, the first air cylinder 61 drives in the reverse direction, the second air cylinder 62 drives in the reverse direction, and finally the first jaw cylinder 64 is opened to complete the blanking of one workpiece.

[0038] In an embodiment, as Figures 1-3and Figure 9 As shown, it further includes a material receiving mechanism 7. The material receiving mechanism 7 is arranged below the material discharging mechanism 6 and is inclined. Specifically, the material receiving mechanism 7 includes a first hopper 71, a second hopper 72 and a third cylinder 73. The second hopper 72 is slidably arranged in the first hopper 71. When receiving materials, the second hopper 72 is driven by the third cylinder 73 to move to the position of the material discharging mechanism 6. After the first jaw cylinder 64 is opened, the workpiece naturally falls and drops into the second hopper 72, and the workpiece slides down along the second hopper 72 and the first hopper 71. After the material receiving is completed, the second cylinder 73 resets, so that the second hopper 72 moves away from the material discharging mechanism 6 to avoid affecting the processing of the workpiece. If the workpiece drops directly, it may cause damage to the workpiece.

[0039] In an embodiment, as Figures 1-3 and Figure 10 shown, since the processing area 13 is relatively narrow, it may be very difficult to directly place the workpiece to be processed on the calibration mechanism by the robotic arm. Therefore, it further includes an up-and-down grasping mechanism 8 arranged directly above the V-shaped cavity 13. The workpiece to be processed is grasped by the robotic arm to the up-and-down grasping mechanism 8, and then the workpiece to be processed is moved down to the calibration mechanism by the up-and-down grasping mechanism 8. Specifically, the up-and-down grasping mechanism 8 includes a cylinder bracket 81, a guide post 82, a connecting plate 83, a fourth cylinder 84 and a second jaw cylinder 85. The fourth cylinder 84 is arranged on the cylinder bracket 81. The second jaw cylinder 85 is connected to the fourth cylinder 84 through the connecting plate 83. The guide post 82 is slidably arranged on the cylinder bracket 81, and one end of it is fixedly connected to the connecting plate 83. The fourth cylinder 84 is used to drive the second jaw cylinder 85 to move up and down. When the third cylinder 84 drives the second jaw cylinder 85 to move the workpiece to be processed to the calibration mechanism 2, the second jaw cylinder 85 is opened to realize the feeding of the workpiece to be processed.

[0040] To make the whole cutting process clearer, the whole process is described as follows; specifically, as Figures 1-11As shown, the workpiece to be processed is moved to the second jaw cylinder 85 by a manipulator. After the second jaw cylinder 85 clamps the workpiece to be processed, the second jaw cylinder 85 is driven by the fourth cylinder 84 to move onto the V-shaped cavity 26. The second jaw cylinder 85 is opened to make the workpiece to be processed fall into the V-shaped cavity 26. The calibration plate 24 is driven by the first actuator 25 to move upward to adjust the position of the workpiece to be processed; then, the first actuator 25 drives the calibration plate 24 to reset. Then, the first servo motor 422 drives the first lead screw 424 to rotate, thereby driving the second inner lining jaw 41 to insert into and clamp the workpiece to be processed; the first servo motor 422 rotates in the reverse direction, and then the second servo motor 426 drives the second lead screw 428 to rotate, so that the second inner lining jaw 41 moves to the rotary spindle mechanism 3 and drives it to move towards the first inner lining jaw 32 here, so that the first inner lining jaw 32 inserts into and clamps the workpiece to be processed; the first inner lining jaw 32 is driven by the motor 31 to make the workpiece rotate rapidly. The third servo motor 531 drives the third lead screw 533 to rotate, thereby driving the blade 52 to move horizontally to adjust the position of the blade 52. Then, the fourth servo motor 535 drives the fourth lead screw 537 to rotate, so that the blade 52 moves towards the workpiece to be processed, and then the workpiece to be processed is cut. After the first workpiece is cut, the fourth servo motor 535 is driven in the reverse direction to make the blade 52 retract. The third servo motor 531 is driven again to adjust the position of the blade 52, and the above operations are repeated until the entire workpiece to be processed is cut; then, the first cylinder 61 drives the first jaw cylinder 64 to move to the workpiece, the workpiece is clamped by the first jaw cylinder 64, and then the slave sub-shaft mechanism 4 is separated from the workpiece. Then, the second cylinder 62 drives the workpiece to be separated from the first inner lining jaw 32, and then the first cylinder 61 is driven in the reverse direction, and the second cylinder 62 is driven in the reverse direction; the third cylinder 73 drives the second hopper 72 to move to the blanking mechanism 6, the first jaw cylinder 64 is opened, and the workpiece slides down along the second hopper 72 and the first hopper 71; after the blanking is completed, the second cylinder 73 resets.

[0041] The above is only a preferred embodiment of the present invention and is not used to limit the scope of implementation of the present invention; if the present invention is modified or equivalently replaced without departing from the spirit and scope of the present invention, it should be covered by the protection scope of the claims of the present invention.
