[0032] It should be further explained that the transmission gear 113 is meshed with the driving gear plate 103 and the driven gear plate 110, and one end of the driving shaft 104 is connected to the industrial motor to achieve the effect of power input. The speed of the industrial motor is controlled by an industrial computer.

[0033] It is worth further explaining that holes and grooves are provided on the four sides of the support base 101 to facilitate the installation and connection of the support base 101.

[0035] It is worth further explaining that when the movable threaded shaft 132 rotates, the clamping strip 114 can be driven to move through the threaded connection.

[0036] Furthermore, a transmission connecting shaft 134 is rotatably provided on one side wall of the slot 112 , and a transmission bevel gear 133 is fixedly connected to the top end of the transmission connecting shaft 134 , and the transmission bevel gear 133 is meshed with the driven bevel gear 123 .

[0038] Furthermore, an annular rack 137 is provided inside the sleeve protection plate 109 , and the adjusting gear 135 is meshed with the annular rack 137 .

[0039] It is worth mentioning that when the three-jaw chuck 111 rotates, it can drive the adjusting gear 135 and the annular rack 137 to rotate relative to each other. At this time, the adjusting gear 135 is meshed with the annular rack 137, thereby driving the adjusting gear 135 to rotate. At this time, the adjusting gear 135 rotates and then drives the transmission bevel gear 133 to rotate through the transmission connecting shaft 134. At this time, the transmission bevel gear 133 is meshed with the driven bevel gear 123, driving the driven bevel gear 123 to rotate, thereby controlling and driving the clamping strip 114 to move.

[0040] Furthermore, an auxiliary toothed disc 126 is rotatably provided in the auxiliary toothed cavity 129 , and the auxiliary toothed disc 126 is mounted on the outer end surface of the driven shaft 116 . An active toothed cavity 130 is provided in the main disk box 105 , and a power toothed disc 125 is rotatably provided in the active toothed cavity 130 , and the power toothed disc 125 is mounted on the outer end surface of the active shaft 104 .

[0041] Furthermore, a gear chamber 128 is provided between the auxiliary tooth chamber 129 and the active tooth chamber 130 . The gear chamber 128 is in communication with the auxiliary tooth chamber 129 and the active tooth chamber 130 . A detachable transmission gear 127 is rotatably provided in the gear chamber 128 .

[0042] It should be further explained that the transmission gear 127 is gear-engaged with the auxiliary gear plate 126 and the power gear plate 125 .

[0043] Furthermore, a sealing plate 115 is installed at one end of the auxiliary gear chamber 129, and a main box sealing plate 120 is installed at one end of the main disk box 105. The sealing plate 115 and the main box sealing plate 120 have a stable sealing effect. A transmission gear box 138 is installed at the intersection of the sealing plate 115 and the main box sealing plate 120. The transmission gear box 138 is arranged on one side of the gear chamber 128, and a flip box plate 118 is installed at the front end of the transmission gear box 138.

[0044] It should be further explained that when the flip box plate 118 is flipped and closed, the gear chamber 128 can be sealed to protect the transmission.

[0045] Furthermore, a rotation speed monitor 107 is installed at the top of the transmission gear box 102 , and a rotation speed detection head 131 is provided at the bottom of the rotation speed monitor 107 . One end of the bottom of the rotation speed detection head 131 extends to the auxiliary tooth cavity 129 .

[0046] It is worth further explaining that the speed detection head 131 can detect the speed of the auxiliary gear disc 126, thereby achieving the effect of speed monitoring. At the same time, a signal line is provided at one end of the speed monitor 107 to connect to an industrial computer, and the detected speed information of the auxiliary gear disc 126 is output to the industrial computer through the signal line for real-time monitoring.

[0047] It is worth further explaining that the speed monitored by the speed monitor 107 is compared with the speed of the industrial motor, and then by monitoring the speed of the auxiliary gear disc 126 and the power gear disc 125, when a fault occurs, the operator can be notified at the first time, thereby facilitating immediate replacement and maintenance of parts.

[0048] When using this solution, first drive the support base 101 to move into the shaft processing lathe, and use the holes and grooves on the four sides of the support base 101 to facilitate installation and stable connection. At this time, connect the driving shaft 104 to the industrial motor, and use the industrial computer to adjust the speed and start and stop the industrial motor.

[0049] When shaft parts need to be processed at this time, according to the specifications of the parts to be processed, if the parts can be installed axially, the parts will be installed to the front end of the active shaft 104, and the active shaft 104 controlled by the industrial computer will be started, and the active shaft 104 will rotate to drive the parts to be processed installed at the front end to rotate, thereby realizing the basic support work.

[0050] When the shaft parts to be processed cannot be installed and processed under normal circumstances, first insert a limit rod into the limit groove on the side of the sleeve protection plate 109 to limit the rotation of the sleeve protection plate 109. At this time, after inserting one end of the shaft parts into the slot 112, the processing worker installs the transmission gear 113 at the front end of the transmission base 106, and meshes the transmission gear 113 with the active toothed disc 103 on one side and the driven toothed disc 110 on the other side. At this time, under the control of the industrial computer, the active shaft 104 is driven to rotate slowly. At this time, as the active shaft 104 rotates and the active toothed disc 103 rotates and the transmission gear 113 gear meshes, the driven toothed disc 110 on the other side is driven to rotate slowly. At this time, as the three-jaw chuck 111 rotates, it can drive the adjusting gear 135 and the annular rack 137 to rotate relative to each other. At this time, by adjusting the gear 135 and the annular rack 1 37 meshes, thereby driving the adjusting gear 135 to rotate. At this time, the adjusting gear 135 rotates and then drives the transmission bevel gear 133 to rotate through the transmission connecting shaft 134. At this time, the transmission bevel gear 133 meshes with the driven bevel gear 123, driving the driven bevel gear 123 to rotate. At this time, the movable threaded shaft 132 is threadedly connected with the clamping strip 114, thereby driving the clamping strip 114 to move telescopically, and then driving the clamping strips 114 on each side to move closer to each other, thereby achieving in the process of rotation of the three-jaw chuck 111, the clamping strips 114 on each side gradually realize the axial stable clamping of the shaft parts to be processed, and the rotation of the three-jaw chuck 111 drives the shaft parts to be processed gradually close to the rotation center position of the three-jaw chuck 111, while realizing the part clamping work, it can also stabilize the center position of the shaft parts to ensure the processing accuracy.

[0051] In this process, since the telescopic movement of the clamping strip 114 is achieved through a precise threaded connection, that is, through the threaded connection between the movable threaded shaft 132 and the clamping strip 114, the clamping force can be accurately adjusted to avoid unnecessary damage to shaft parts.

[0052] As the three-jaw chuck 111 continues to rotate, the shaft parts to be processed are gradually pushed toward their rotation center position. This process not only achieves stable axial clamping of the shaft parts, but also ensures the positioning accuracy of the shaft parts in the radial direction by fine-tuning the expansion and contraction of the clamping strips 114 on each side. This design fully takes into account the high requirements for precision and stability in the processing of shaft parts, and effectively improves processing efficiency and product quality.

[0053] In addition, during the entire processing process, industrial computers achieve real-time monitoring and adjustment of the entire processing process by precisely controlling the movement of each component. This can not only promptly detect and correct deviations in the processing process, but also flexibly adjust processing parameters such as rotation speed, clamping force, etc. according to the processing requirements of different shaft parts, thereby meeting diverse processing needs.

[0054] Subsequently, the staff removed the transmission gear 113 and cancelled the limit of the protective plate 109. The staff manually flipped open the flip box plate 118 on the rear side of the transmission gear box 102 and installed the transmission gear 127 in the gear chamber 128. At this time, the transmission gear 127 is meshed with the auxiliary toothed disc 126 and the power toothed disc 125 gears to achieve the transmission effect. At this time, the industrial computer controls and drives the active shaft 104 to rotate, and then drives the power toothed disc 125 to rotate through the rotation of the active shaft 104, and drives the auxiliary toothed disc 126 to rotate through the transmission gear 127. At this time, the auxiliary toothed disc 126 rotates and then drives the driven shaft 116 to rotate, and then drives the three-jaw chuck 111 to rotate to achieve the processing speed of the shaft parts process, which is convenient for the staff to carry out subsequent work results.

[0055] After the processing is completed, the processing worker can operate the industrial computer to control the three-jaw chuck 111 to reverse, gradually release the clamping of the shaft parts, and then easily remove the processed shaft parts from the equipment.

[0056] When multiple shaft parts are being processed, the active shaft 104 and the three-jaw chuck 111 rotate in coordination, and the motion status and processing progress of each shaft can be monitored in real time through the industrial computer. When multiple shaft parts of different specifications need to be processed, the industrial computer can automatically adjust the rotation speed, clamping force and processing path of the active shaft 104 and the three-jaw chuck 111 according to the preset processing parameters to ensure that each part can be processed accurately and efficiently.

[0057] After processing is completed, the staff can remove the processed shaft parts from the equipment through simple operations and prepare to process the next batch of parts. The entire processing process is efficient, precise and stable.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
