[0025] Reference Figures 1 to 3The first aspect of this application provides a spindle mechanism, including a spindle assembly and a brake assembly. The spindle assembly includes a spindle seat 101 and a spindle rod 102. The spindle rod 102 is rotatably inserted into the spindle seat 101. The spindle rod 102 is provided with a pulley 103, which is used to connect to the drive wheel of the spindle motor via a belt. The brake assembly includes a brake disc 104 and a brake pad 105. The brake disc 104 is disposed on the pulley 103, and the brake pad 105 is disposed on one side of the brake disc 104. The brake pad 105 can abut against or move away from the brake disc 104. An expansion sleeve 106 is provided between the pulley 103 and the spindle rod 102. The end of the expansion sleeve 106 near the brake disc 104 is provided with a tapered end 107, which is engaged with the brake disc 104.

[0026] During operation, the spindle motor operates, driving the pulley 103 to rotate via the drive wheel and belt, thereby rotating the spindle 102. When stopping is required, the spindle motor stops, the brake pad 105 approaches and abuts against the brake disc 104 to stop the brake disc 104, and the spindle 102 stops rotating. By placing the brake disc 104 on the pulley 103, and providing an expansion sleeve 106 between the pulley 103 and the spindle 102, with one end of the expansion sleeve 106 near the brake disc 104 being a tapered end 107 that engages with the brake disc 104, the stability of the brake disc 104 is improved, preventing it from shaking, ensuring smooth operation, and enhancing reliability and safety.

[0027] Reference Figure 1 The brake disc 104 has two brake pads 105, which are located on the same side of the brake disc 104 and symmetrically positioned at both ends of the disc. By simultaneously applying the brake disc 104 with both brake pads 105, the brake disc 104 can be brought to a stop. Compared to braking with a single brake pad 105 in the prior art, this improves braking stability and reliability, enhances wear resistance, and extends service life.

[0028] Reference Figure 1 and Figure 3As can be conceived, the brake assembly also includes a driving component, which includes a mounting base 108 and a cylinder 109. The cylinder 109 is disposed on the mounting base 108 and is connected to the brake pad 105. The cylinder 109 drives the brake pad 105 to move closer to or away from the brake disc 104, resulting in a simple structure and stable operation. The telescopic end of the cylinder 109 is disposed on the output block 110, which is equipped with a fixing plate 111. The brake pad 105 is disposed on the fixing plate 111. Furthermore, the mounting base 108 includes a side plate 112 and a connecting plate 113. The side plates 112 are symmetrically arranged on both sides, and the connecting plate 113 is disposed between the side plates 112. The cylinder 109 is disposed on the connecting plate 113, with its telescopic end passing through the connecting plate 113. The output block 110 can slide along the side plate 112 under the action of the cylinder 109. By symmetrically positioning the side plates 112 on both sides to guide the output block 110, the stability of the brake pad 105 movement can be ensured, thereby making the brake disc 104 stop more smoothly and improving the reliability and safety of the operation.

[0029] It should be noted that the drive component can also adopt a structure of screw and nut seat, or a structure of gear and rack, as long as the brake pad 105 can abut or move away from each other, and this application does not limit this.

[0030] Reference Figure 1 In this embodiment, the spindle housing 101 includes a bushing 114 and an end cap 115. Bearing portions are respectively provided at both ends of the bushing 114, and the spindle 102 passes through the bearing portions. The end caps 115 are located at both ends of the bushing 114 and press against the bearing portions. The bearing portions include a deep groove ball bearing 116 and an angular contact bearing 117. The deep groove ball bearing 116 is located at the end of the bushing 114 near the pulley 103, and the angular contact bearing 117 is located at the end of the bushing 114 away from the pulley 103. By using an angular contact bearing 117 at the end of the bushing 114 away from the pulley 103, compared to the thrust bearings used in related technologies, the operation is smoother and the service life is longer. It is easy to understand that the spindle seat 101 also includes an inner spacer 118 and an outer spacer 119. The inner spacer 118 is sleeved on the spindle 102, and both ends of the inner spacer 118 abut against the inner ring of the bearing part. The outer spacer 119 is inserted into the bushing 114, and both ends of the outer spacer 119 abut against the outer ring of the bearing part, thereby improving the stability and reliability of the spindle 102.

[0031] Reference Figure 1 and Figure 2In some embodiments of this application, to prevent the cookware from being scratched during clamping and affecting quality, vacuum adsorption is typically used to fix the cookware. In this case, the main spindle 102 is provided with a vacuum channel 120, and a rotary joint 121 is provided at the end of the main spindle 102 near the pulley 103. The rotary joint 121 communicates with the vacuum channel 120 and is used to connect to a vacuum system. By providing the rotary joint 121, the rotary joint 121 can rotate relative to the main spindle 102, thereby improving the stability and safety of the operation.

[0032] The first aspect of this application provides a cookware bottom sanding machine, including the spindle mechanism described in the embodiment of the first aspect of this application.

[0033] When the spindle mechanism described in the first aspect of this application is applied to a cookware sander, the spindle motor operates, driving the pulley 103 to rotate via the drive wheel and belt, thereby rotating the spindle 102. When it is necessary to stop, the spindle motor stops operating, the brake pad 105 approaches and abuts against the brake disc 104 to stop the brake disc 104, and the spindle 102 stops rotating. By setting the brake disc 104 on the pulley 103, and providing an expansion sleeve 106 between the pulley 103 and the spindle 102, with one end of the expansion sleeve 106 near the brake disc 104 being a tapered end 107 that engages with the brake disc 104, the stability of the brake disc 104 can be improved, preventing the brake disc 104 from shaking, ensuring smooth operation, and improving reliability and safety.

[0034] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
