It also includes: a transmission belt 9, which is arranged on the rotating shaft 7; and a driving motor 10, which is arranged on the machining lathe 5 and drives the transmission belt 9 to rotate.
[0037] In this embodiment, the machine tool design integrates an innovative oil brake system to ensure dynamic control and safety during the processing. The main structure of the machine tool includes a stable processing lathe 5, which provides basic support for the operation of the machine tool.

[0038] Furthermore, the processing table 1 has a circumferentially arranged loading station 101, a processing station 102, a cleaning station 103 and a unloading station 104; and also includes:
[0039] The clamping assembly 2 is rotatably arranged on the processing table 1, and after rotating, it passes through the loading station 101, the processing station 102, the cleaning station 103 and the unloading station 104 in sequence. The clamping assembly 2 has an air cavity 2011, and one end of the air cavity 2011 has a connecting hole 2012, and the other end has a plurality of air holes 2013;
[0040] The suction connector 3 is movably arranged on the processing table 1 and moves between the loading station 101 and the processing station 102;
[0041] The blowing joint 4 is movably arranged on the processing table 1 and moved to the cleaning station 103. After the clamping assembly 2 is rotated, the connecting hole 2012 is connected with the suction joint 3 or the blowing joint 4. The clamping assembly 2 comprises: a first clamping member 201 and a second clamping member 202. The first clamping member 201 and the second clamping member 202 are arranged close to or far from each other. They are close to each other for clamping materials and far from each other for releasing materials. The first clamping member 201 and the second clamping member 202 both have a guide part 203. The processing table 1 has a circular guide groove 105. The guide part 203 is slidably arranged in the circular guide groove 105. The air cavity 2011, the connecting hole 2012 and a plurality of air holes 2013 are arranged on the first clamping member 201. The clamping assembly 2 further includes: a rotating rod 204, which is rotatably arranged on the processing table 1; a first connecting rod 205 and a second connecting rod 206, one end of each of which is hinged to the rotating rod 204, one end of the first clamping member 201 is hinged to the other end of the first connecting rod 205, and one end of the second clamping member 202 is hinged to the other end of the second connecting rod 206. The clamping assembly 2 has two groups, which are symmetrically rotatably arranged on the processing table 1, and the rotating rod 204 is an elastic telescopic rod. The rotating axis of the rotating rod 204 is eccentrically arranged relative to the circular guide groove 105. After the rotating rod 204 rotates eccentrically, the distance between the first clamping member 201 and the second clamping member 202 gradually decreases from the loading station 101 to the processing station 102, and gradually increases from the processing station 102 to the unloading station 104.
[0042] In this embodiment, the processing table 1 is designed as a circular layout, with four stations distributed around it: a loading station 101, a processing station 102, a cleaning station 103 and a unloading station 104, forming an efficient material flow path. The central rotating device of the clamping assembly 2, the air suction joint 3 is responsible for moving between the loading station 101 and the processing station 102. After the air suction joint 3 is connected to the connecting hole 2012, the air hole 2013 of the clamping assembly 2 absorbs the material through negative pressure to ensure stable transportation to the processing area. The blowing joint 4 is positioned at the cleaning station 103 and is movable in the cleaning station 103. The residual chips and coolant after processing are removed by blowing force to ensure the cleanliness of the workpiece and improve the surface quality.
[0043] Workflow and operation: Loading stage: The material is placed in the loading station 101, and the suction joint 3 is connected to the air cavity 2011 of the clamping component 2 through the connecting hole 2012, and the negative pressure is started to adsorb the material. While the clamping component 2 maintains adsorption, it steadily drives the material to move to the processing station 102 for processing. During the processing, the clamping component 2 and the negative pressure act on the material together to improve the stability of the material and ensure accurate positioning. Cleaning stage: After the processing is completed, the clamping component 2 automatically turns to the cleaning station 103, and the blowing joint 4 is connected to the air cavity 2011 of the clamping component 2 through the connecting hole 2012. The wind blows out in the air hole 2013 to remove the chips and liquid. Unloading stage: After cleaning, the clamping component 2 continues to turn to the unloading station 104, and the material falls naturally or with mechanical assistance to complete the cycle. Significantly improve efficiency, reduce manual intervention, continuous processing, and increase production capacity. Pneumatic suction and release control materials, reduce damage, and improve processing accuracy. Automatic cleaning, reduce defective rate, and improve product quality. The clamping assembly 2 includes a first clamping member 201 and a second clamping member 202, which are arranged relative to each other and can achieve accurate clamping and release of materials by moving closer to or away from each other. The first clamping member 201 and the second clamping member 202 both have a guide portion 203, and a circular guide groove 105 is provided on the processing table 1 to provide a sliding track for the guide portion 203.
[0044] Workflow and operation: When the first clamping member 201 and the second clamping member 202 approach each other through the driving mechanism, their guide parts 203 slide along the circular guide groove 105 to clamp the material and ensure stability during processing. After processing, through reverse operation, the guide parts 203 of the first clamping member 201 and the second clamping member 202 slide away along the circular groove and separate from each other, releasing the material, so that the material can be easily removed to the next process or unloading. The double clamping member design ensures that the material is evenly stressed all around, reduces deformation, and improves processing accuracy. The precise matching of the guide groove and the guide part 203 ensures that the clamping member slides smoothly without obstruction, improving positioning accuracy.
[0045] The two groups of clamping components 2 are symmetrically installed on the processing table 1, which can realize the continuity of loading and unloading. When one group of clamping parts clamps the material into the unloading station 104, the other group of clamping parts clamps the material into the processing station 102. The rotating rod 204 can not only rotate, but also has a telescopic function. This design enables the clamping component 2 to automatically adjust according to the requirements of the processing process to adapt to different workpiece sizes or shapes. The design of the rotating rod 204 eccentric to the circular guide groove 105 enables the distance between the first clamping part 201 and the second clamping part 202 to be dynamically adjusted during rotation. The first connecting rod 205 and the second connecting rod 206 are hinged to the rotating rod 204, and then hinged to the first clamping part 201 and the second clamping part 202 to form a linkage. The rotation of the rotating rod 204 drives the clamping parts to move closer or farther synchronously, thereby realizing accurate clamping and release of materials.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
