[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example 1 This utility model provides a swing structure for a polishing machine, such as Figures 1 to 6 As shown, it includes: a drive shaft 1 and a swing assembly. A transmission gearbox 2 is provided on one side of the drive shaft 1. The transmission gearbox 2 has a bevel gear set inside, which is used to transmit the rotational motion of the transmission gearbox 2 to the swing mechanism. The swing assembly includes a gear 3, a rack 4, a special bearing seat 5, and a bearing seat 6 with a mounting bracket. The gear 3 is a gear, the rack 4 is a rack, and the gear 3 and rack 4 mesh with each other. The special bearing seat 5 is a special bearing seat. (The special bearing seat 5 has mounting holes 14 inside, and the number of mounting holes 14 is set to multiple. The special bearing seat 5 has a bearing inside, and the special bearing seat 5 is mounted on the outer surface of the drive shaft 1 through the bearing. The diameter of the mounting hole 14 located at the upper left corner of the special bearing seat 5 coincides with the outer diameter of the bearing (see...) Figure 5This minimizes the dimensions of the special bearing housing, allowing it to be installed on the end face of the existing polished crossbeam 15. It supports the drive shaft 1, adapts to oscillating conditions, and reduces vibration and wear. The seated bearing housing 6 is used to fix and support the drive shaft 1, ensuring its smooth rotation and reducing friction. Gear 3 is connected to one edge of the outer surface of the drive shaft 1. The drive shaft 1 reciprocates through the meshing of gear 3 and rack 4. Both the special bearing housing 5 and the seated bearing housing 6 are fitted onto the outer surface of the drive shaft 1, and the drive shaft 1 rotates within the special bearing housing 5 and the seated bearing housing 6 respectively. A drive component 11 is provided on one end face of the transmission gearbox 2. The drive component 11 (using a reversible motor, controlled by a control system according to a preset timing sequence, first driving the drive shaft 1 to rotate in the forward direction for a predetermined duration, then automatically switching to the reverse direction) The drive end of the drive member 11 is set to the horizontal direction, and the transmission gearbox 2 converts the drive end of the drive member 11 from the horizontal direction to the vertical direction. The rack 4 is provided with multiple limiting members 12, and the multiple positioning members 12 are distributed in an equidistant array from the end of the rack 4 near the gear 3 to the end away from the gear 3. It also includes a polishing beam 15 on one side of a special bearing seat 5 and a bearing seat 6 with a seat. The drive shaft 1 is connected to the outer surface of the polishing beam 15 through the special bearing seat 5 and the bearing seat 6 with a seat. The positioning members 12 fix the rack 4 on the support 13. The polishing beam 15 includes (power equipment, polishing platform, polishing equipment and control equipment), which are all existing technologies in this technical field and will not be described in detail here.

[0019] By cooperating with the transmission shaft 1 and the transmission gearbox 2, the lateral rotational motion of the drive component 11 is converted into longitudinal rotation. Then, through the meshing of the gear 3 and the rack 4, the rotational motion is converted into stable horizontal reciprocating oscillation, thereby improving polishing uniformity and processing efficiency.

[0020] In operation, the operator first activates the drive unit 11 to supply power to the transmission gearbox 2. The power output from the drive unit 11 then passes through the transmission gearbox 2, driving the half-couplings 10 on both sides to rotate synchronously. The half-couplings 10 drive the drive shaft 1 to rotate. The drive shaft 1 rotates within the specially designed bearing housing 5 and the bearing housing 6, which limit its rotation and prevent deviation. The rotation of the drive shaft 1 also drives the gear 3 to rotate via the expansion sleeve 8. The gear 3 meshes with the rack 4, reciprocating in motion. The rack 4 is fixed to the support 13 by the positioning element 12. The meshing motion of the gear 3 and rack 4 drives the polishing beam 15 to reciprocate as well. Through the cooperation of the drive shaft 1 and the transmission gearbox 2, the lateral rotation of the drive unit 11 is converted into longitudinal rotation. Furthermore, the meshing of the gear 3 and rack 4 transforms the rotational motion into a stable horizontal reciprocating oscillation, improving polishing uniformity and processing efficiency.

[0021] Specifically, one end face of the drive shaft 1 is fixedly connected to the connecting shaft 9. The drive shaft 1 is connected to the inside of the transmission gearbox 2 through the connecting shaft 9. The transmission gearbox 2 is fixedly installed on the outer surface of the polishing beam 15. A drive component 11 is fixedly installed on one end face of the transmission gearbox 2. When the drive component 11 is started, it drives the connecting shaft 9 to rotate through the transmission gearbox 2. A gear 3 is fixedly installed on the outer surface of the drive shaft 1 away from the edge of the connecting shaft 9 through a shrink sleeve 8. A rack 4 is meshed on the outer surface of the gear 3. The rack 4 is fixed on the support 13 by the positioning component 12. A special bearing seat 5 and a bearing seat 6 are sleeved on the outer surface of the drive shaft 1. The drive shaft 1 is fixedly connected to the polishing beam 15 through the special bearing seat 5 and the bearing seat 6. A half coupling 10 is sleeved on the outer surface of the connecting shaft 9. The special bearing seat 5 has multiple mounting holes 14. A bearing is installed inside the special bearing seat 5. One of the mounting holes 14 coincides with the outer diameter of the bearing.

[0022] To reduce the vibration generated when the transmission gearbox 2 drives the transmission shaft 1 to rotate via the connecting shaft 9, as described in the above example, the following solutions are proposed: Figure 3 As shown, a tensioning sleeve 8 is provided on the gear 3. The tensioning sleeve 8 is located between the gear 3 and the drive shaft 1, and the gear 3 is connected to the drive shaft 1 through the tensioning sleeve 8 to fasten the drive shaft 1 and the gear 3. A connecting shaft 9 is provided inside the transmission gearbox 2. The drive shaft 1 is connected to the transmission gearbox 2 through the connecting shaft 9 to ensure continuous power transmission of the drive shaft 1. Half couplings 10 are provided on both sides of the transmission gearbox 2. The half couplings 10 are sleeved on the outer surface of the drive shaft 1 to buffer the vibration between the transmission gearbox 2 and the drive shaft 1.

[0023] By providing half-couplings 10 on both sides of the transmission gearbox 2, these half-couplings 10 can absorb minor axial and radial deviations of the transmission shaft 1, reduce the instantaneous impact caused by the start-stop or reversal of the drive component 11, and make the transmission of the transmission shaft 1 more stable.

[0024] Working principle: When using this device, the operator first starts the drive unit 11 to send power into the transmission gearbox 2. At this time, the power output by the drive unit 11 passes through the transmission gearbox 2 and drives the half couplings 10 on both sides to rotate synchronously. The half couplings 10 drive the transmission shaft 1 to rotate. When the transmission shaft 1 rotates, it rotates inside the special bearing seat 5 and the bearing seat 6. The special bearing seat 5 and the bearing seat 6 limit the transmission shaft 1 during the rotation process to prevent the transmission shaft 1 from deviating during the rotation process. When the transmission shaft 1 rotates, it drives the gear 3 to rotate through the expansion sleeve 8. When the gear 3 rotates, it drives the polishing beam 15 to reciprocate in the horizontal direction on the fixed rack 4, thereby completing the oscillating characteristic of the polishing machine.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
