[0020] The above-mentioned clamping assembly 2 and motor body 5 are both existing mature technologies. A positioning fixture for machining mechanical parts is disclosed in the Chinese patent with announcement number CN219293352U, wherein the clamping assembly 2 includes a clamping box, a driving motor is installed on the inner surface of the clamping box, a turntable is installed in front of the driving motor, a fixing groove is installed on the outer surface of the turntable, a connecting rod is installed in front of the fixing groove, a clamping arm is installed below the connecting rod, a limiting seat is installed on the left outer surface of the clamping arm, a first clamping block is installed on the left side of the limiting seat, and a compression rod is installed on the left side of the first clamping block.

[0021] Through the arrangement of the clamping box, the clamping arm, the compression rod, the limit seat, the first clamping block, the second clamping block, the driving motor, the turntable, the fixed groove and the connecting rod, when it is necessary to clamp the workpiece, the driving motor inside the clamping box is started, the turntable is driven by the driving motor to rotate, and then the connecting rod fixed by the fixed groove is driven to rotate, the clamping arm passing through the limit seat is moved by the connecting rod, and then the first clamping block and the second clamping block are used to clamp the mechanical parts, and the mechanical parts are positioned to prevent deviation during processing;

[0022] And the clamping box on the clamping assembly 2 is fixedly connected to the annular plate 3;

[0023] The motor body 5 is a stepper motor, which is an electric motor that can convert an electrical pulse signal into a corresponding angular displacement or linear displacement. Whenever an electrical pulse signal is received, the stepper motor will rotate a specific angle or move forward one step, and the angular displacement or linear displacement outputted by the stepper motor is proportional to the number of input pulses. In addition, the speed of the stepper motor is proportional to the pulse frequency, and it also has a self-locking characteristic.

[0024] The above is not described in detail in this embodiment;

[0025] The inner side of the drum 1 is also provided with an automatic cleaning assembly including a pushing assembly 6 fixed to the inner bottom of the drum 1, a circular storage box 7 is fixed to the output end of the pushing assembly 6, and the diameter of the circular storage box 7 is greater than the diameter of the annular plate 3;

[0026] Refer to the attached Figure 3 and attached Figure 4 A plurality of dust suction holes are provided on the top of the circular storage box 7, a dust collector 8 is fixed on the bottom of the inner side of the cylinder 1 and on one side of the pushing assembly 6, a discharge pipe is installed at the output end of the dust collector 8, and the end of the discharge pipe away from the dust collector 8 is connected to an external trash can;

[0027] See attached Figure 2 - Attachment Figure 4 A dust suction hose 9 is installed at the output end of the vacuum cleaner 8, and a discharge hole adapted for the dust suction hose 9 is opened at the bottom of the circular storage box 7. The end of the dust suction hose 9 away from the dust suction hose 9 is installed on the inner side of the discharge hole of the circular storage box 7.

[0028] According to the above structure, when the workpiece needs to be surface treated, the drum 1 is first placed in the designated working area. Then, the workpiece is clamped by the clamping assembly 2 to ensure that the workpiece is firmly fixed in the working area. Once the workpiece is clamped, the workpiece can be processed. During the processing, the vacuum cleaner 8 starts to operate, and at the same time, the vacuum hose 9 and the circular storage box 7 can effectively suck dust to reduce the dust, debris and other impurities generated during processing from adhering to the workpiece or additional equipment.

[0029] When one side of the workpiece is processed, the push assembly 6 starts to operate, causing the suction circular storage box 7 to descend to provide space for the workpiece to be turned over. At this time, the motor body 5 operates to cause the round rod 4 to rotate 180 degrees inside the barrel 1 to turn the workpiece over. Through this step, the workpiece clamped on the workpiece is automatically turned over, so that the other side of the workpiece can be processed, so that both sides can be processed.

[0030] The above automatic flipping operation process can reduce manual intervention and improve production efficiency. The flipping and double-sided processing of the workpiece does not require manual intervention, which reduces production time and labor costs.

[0031] After the other side of the workpiece is processed, the motor body 5 is operated again to reset the workpiece to its initial position. During the whole process, the vacuum hose 9 and the circular storage box 7 can be used to vacuum both sides of the workpiece to ensure that both sides of the workpiece are free of dust, debris and other impurities, thereby improving the overall cleanliness of the workpiece and helping to ensure that the workpiece is easy to accept painting, bonding and other surface treatments because there is no interference from impurities or debris. This is essential to ensure that the appearance and performance of the final product meet the required standards.

[0032] Through the above, the automatic cleaning component not only effectively removes dust, debris and other impurities generated during processing, but also ensures that both sides of the workpiece are vacuumed to meet higher cleanliness requirements;

[0033] See attached Figure 1 - Attachment Figure 3 , and a first magnetic ring is installed on the top of the barrel 1, a second magnetic ring is magnetically connected to the first magnetic ring, and a cover plate 10 is fixed on the inner side of the second magnetic ring.

[0034] According to the above structure, when the device is not in working state, the cover plate 10 can be placed on the top of the drum 1, thereby effectively protecting the internal structure of the drum 1 to prevent it from being damaged, which helps to maintain the reliability and life of the equipment.

[0035] Refer to the attached Figure 1 and attached Figure 3 In addition, a repair groove is provided on the outer side of the barrel 1 near the bottom, and an arc-shaped sealing plate 11 is installed on the inner side of the repair groove of the barrel 1, and an interference fit is provided between the arc-shaped sealing plate 11 and the repair groove;

[0036] According to the above structure, when it is necessary to maintain or replace the inner parts of the barrel 1, the arc-shaped blocking plate 11 can be pulled to release the blocking of the repair groove on the barrel 1 by the arc-shaped blocking plate 11, thereby realizing convenient maintenance or replacement of the inner parts of the barrel 1, which helps to improve the convenience of maintenance;

[0037] In summary, the utility model can realize automatic turning over of the workpiece, so that both sides of the workpiece can be processed, which not only improves the production efficiency but also reduces the workload of the operator because manual intervention in the turning process is no longer required.

[0038] In addition, the utility model has excellent environmental protection characteristics. It can efficiently remove dust, debris and other impurities generated during processing, while ensuring that both sides of the workpiece have been dusted. This can not only prevent dust, debris and other impurities from being attached to the workpiece or accessory equipment during processing, but also help to improve the cleanliness of the workpiece, ensuring that both sides of the workpiece do not contain dust, debris and other impurities, thereby improving the overall cleanliness of the workpiece, and also help to ensure that the workpiece is easy to accept painting, bonding and other surface treatments because there is no interference from impurities or debris.

[0039] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
