[0042] During the process of inserting the honing head 9 into the inner hole of the workpiece 1, the ball 27 will abut against the inner wall of the workpiece 1. During this process, the ball 27 squeezes the adjusting compression spring 16 through the pressure rod 13, the adjusting compression spring 16 is deformed, and the pressure is applied to the pressure sensor 15. Then the honing head 9 drives the pressure rod 13 to make a trial rotation. The staff adjusts the position of the support ring seat 42 according to the feedback pressure value and the design value of the workpiece 1, and then determines the final pressure value.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The sliding assembly 12 includes a horizontal rod 121 bolted to the honing bar 10, and a honing compression spring 122 is supported between the side of the honing bar 10 facing away from the horizontal rod 121 and the honing groove 11 of the honing head 9. The interior of the honing rod 7 is hollow and open at both ends. A driving tube 123 is coaxially slidably arranged in the honing rod 7, and a driving cone 124 is coaxially welded on the driving tube 123. The diameter of the driving cone 124 gradually decreases along the direction from the honing rod 7 to the honing head 9.

[0044] Reference Figure 1 , Figure 2 and Figure 4 The horizontal rod 121 is used to abut against the conical surface of the driving cone 124. A fine grinding strip 19 is inserted into the side of the honing strip 10 that is away from the horizontal rod 121. The length direction of the fine grinding strip 19 is parallel to the axial direction of the honing head 9. Both ends of the fine grinding strip 19 in the length direction are provided with guiding inclined surfaces 20.

A driving disk 182 is provided on the honing rod 7 in a sliding sleeve. The driving disk 182 is coaxially covered with an outer cover shell 813 with a C-shaped cross-section. The outer cover shell 813 is bolted together by two half parts. The outer cover shell 813 is bolted to the piston rod of the driving cylinder 181. A connecting plate 184 is welded between the driving disk 182 and the driving tube 123. An avoidance slot 185 for the connecting plate 184 to slide is provided on the honing rod 7.

[0046] Then the control system starts the rotating motor 82, and the rotating motor 82 drives the honing head 9 to rotate through the honing rod 7, and at the same time drives the piston rod of the oil cylinder 181 to push the outer cover shell 813 to descend, and the outer cover shell 813 drives the driving disk 182 to descend synchronously, and the driving disk 182 drives the driving tube 123 to descend synchronously through the connecting plate 184, and the driving tube 123 drives the driving cone 124 to push the horizontal rod 121, and the horizontal rod 121 drives the honing stick 10 to slide along the radial direction of the axis of the honing head 9.

[0047] The honing compression spring 122 is deformed under pressure, and at the same time, the honing bar 10 drives the fine grinding bar 19 to abut the inner wall of the workpiece 1. As the pressure change value fed back by the pressure sensor 15, the driving cylinder 181 synchronously extends or retracts its piston rod, so that the fine grinding bar 19 hones the inner wall of the workpiece 1, and then under the action of the lifting cylinder 61, the honing head 9 hones the top and bottom of the workpiece 1.

[0048] During the rolling contact between the ball 27 and the inner wall of the workpiece 1, the pressure sensor 15 constantly feeds back the pressure value to the control system until the pressure values ​​fed back to the pressure sensor 15 from the top and bottom of the inner wall of the workpiece 1 meet the design requirements of the workpiece 1 and the values ​​are consistent. Then, the honing of the workpiece 1 is stopped. During the entire processing of the workpiece 1, the cooling pipe 17 continuously sprays coolant on the workpiece 1, thereby improving the processing accuracy of the workpiece 1.

The outer cover shell 813 is provided with brush grooves 23 for the brushes 22 to slide.

[0050] Reference Figure 2 , Figure 3 and Figure 4 The brush 22 is supported by a conductive spring 24 between the brush groove 23 and the side facing away from the conductive ring 21. A transmission wire 25 electrically connected to the brush 22 is bolted to the outer cover 813. The other end of the transmission wire 25 is connected to the control panel 29. A collecting wire harness 26 is passed through the drive tube 123. The collecting wire harness 26 is used to electrically connect the pressure sensor 15 and the conductive ring 21.

[0051] When the pressure sensor 15 feeds back the pressure value change of the inner wall of the workpiece 1 to the control system, the electrical signal is transmitted in the direction of the pressure sensor 15, the collecting wire bundle 26, the conductive ring 21, the brush 22 and the transmission wire 25, so as to ensure the timeliness of the signal transmission, thereby ensuring the accuracy of the inner wall processing of the workpiece 1.

[0052] The implementation principle of a vertical honing machine in an embodiment of the present application is as follows: a worker mounts a workpiece 1 on a triangular chuck 43, and then starts the hydraulic pump 62 through the control system. The hydraulic pump 62 controls the hydraulic oil input into the lifting cylinder 61, so that the lifting platform 5 drives the honing rod 7 to descend until the honing head 9 on the honing rod 7 is inserted into the hole of the workpiece 1. Then, the rotating motor 82 is started through the control system. The rotating motor 82 drives the honing rod 7 to rotate, and the honing rod 7 drives the honing head 9 to rotate synchronously. The circulating pump sprays coolant from the cooling pipe 17 to the top of the workpiece 1.

[0053] During the process of inserting the honing head 9 into the inner hole of the workpiece 1, the ball 27 will abut against the inner wall of the workpiece 1. During this process, the ball 27 squeezes the adjusting compression spring 16 through the pressure rod 13, the adjusting compression spring 16 is deformed, and the pressure is applied to the pressure sensor 15. Then the honing head 9 drives the pressure rod 13 to make a trial rotation. The staff adjusts the position of the support ring seat 42 according to the feedback pressure value and the design value of the workpiece 1, and then determines the final pressure value.

[0054] Then the control system starts the rotating motor 82, and the rotating motor 82 drives the honing head 9 to rotate through the honing rod 7, and at the same time drives the piston rod of the oil cylinder 181 to push the outer cover shell 813 to descend, and the outer cover shell 813 drives the driving disk 182 to descend synchronously, and the driving disk 182 drives the driving tube 123 to descend synchronously through the connecting plate 184, and the driving tube 123 drives the driving cone 124 to push the horizontal rod 121, and the horizontal rod 121 drives the honing stick 10 to slide along the radial direction of the axis of the honing head 9.

[0055] The honing compression spring 122 is deformed under pressure, and at the same time, the honing bar 10 drives the fine grinding bar 19 to abut the inner wall of the workpiece 1. As the pressure change value fed back by the pressure sensor 15, the driving cylinder 181 synchronously extends or retracts its piston rod, so that the fine grinding bar 19 hones the inner wall of the workpiece 1, and then under the action of the lifting cylinder 61, the honing head 9 hones the top and bottom of the workpiece 1.

[0056] During the rolling contact between the ball 27 and the inner wall of the workpiece 1, the pressure sensor 15 constantly feeds back the pressure value to the control system until the pressure values ​​fed back to the pressure sensor 15 from the top and bottom of the inner wall of the workpiece 1 meet the design requirements of the workpiece 1 and the values ​​are consistent. Then, the honing of the workpiece 1 is stopped. During the entire processing of the workpiece 1, the cooling pipe 17 continuously sprays coolant on the workpiece 1, thereby improving the processing accuracy of the workpiece 1.

[0057] When the pressure sensor 15 feeds back the pressure value change of the inner wall of the workpiece 1 to the control system, the electrical signal is transmitted in the direction of the pressure sensor 15, the collecting wire bundle 26, the conductive ring 21, the brush 22 and the transmission wire 25, so as to ensure the timeliness of the signal transmission, thereby ensuring the accuracy of the inner wall processing of the workpiece 1.
