[0031] In summary, the present invention proposes a workpiece loading and unloading device for a CNC horizontal lathe, which fixes the device on the CNC horizontal lathe table through two sets of long fixing plates 11, so that the clamping assembly 2 is above the CNC lathe processing table. When the user wants to load the workpiece to be processed, the hydraulic cylinder 19 is first started to extend or retract the hydraulic cylinder 19, and the hydraulic cylinder 19 will push the clamping assembly 2 to move horizontally, and the sliding ring 17 at the upper end of the clamping assembly 2 will slide horizontally along the outer periphery of the long rod 16. This operation utilizes the supporting effect of the sliding ring 17 and the long rod 16. In order to improve the stability of the movement of the clamping assembly 2, when the clamping assembly 2 is adjusted horizontally to above the workpiece, the user can turn on the first motor 112, and the first motor 112 rotates forward to drive the active roller 113 to rotate. The transmission of the belt 114 drives the transmission roller 115 and the first screw rod 117 to rotate. The first screw rod 117 drives the limit block 116 to move downward along the long groove 12 on one side thereof. At this time, the limit block 116 drives the lifting plate 13 and the clamping assembly 2 to move downward until the clamping assembly 2 is lowered to the workpiece to be processed, and the clamping assembly 2 can use its The two groups of clamping plates 25 at the lower end are clamped and limited on both sides of the workpiece. When the clamping assembly 2 has clamped the workpiece, the first motor 112 is rotated in the opposite direction. The first motor 112 drives the first screw rod 117 to rotate in the opposite direction. The first screw rod 117 drives the limit block 116, the lifting plate 13, the clamping assembly 2 and the workpiece to move upward, so that the workpiece to be processed is above the lathe processing table again. The hydraulic cylinder 19 can then be started, and the hydraulic cylinder 19 can be extended and retracted to drive the clamping assembly 2 and the workpiece to move horizontally to the left or right. When the workpiece is adjusted to be just above the processing table, it can be rotated forward again. The first motor 112, the reverse rotation driving effect of the first motor 112 causes the limit block 116, the lifting plate 13 and the clamping assembly 2 and the workpiece to perform a downward movement until the workpiece is lowered onto the lathe processing table, and the lathe is ready to perform subsequent processing on the workpiece. This arrangement can utilize the level of the driving support assembly 1 and the cooperation of the lifting driving components to automatically load and unload the workpiece. At the same time, the device can also adjust the loading and unloading stroke and the material taking and releasing position according to actual production needs, with a wide range of applications, avoiding time-consuming and labor-intensive manual loading, and improving the practicality of the device;

[0032] The user can also adjust the two groups of clamping plates 25 on the clamping assembly 2 according to the size of the workpiece to be loaded and unloaded. First, start the second motor 27. The forward or reverse rotation of the second motor 27 will drive the forward and reverse screw rods 23 to rotate. Since the limit sliding block 24 is limited in the inner cavity of the long empty slot 22, the forward and reverse rotation of the forward and reverse screw rods 23 will drive the two groups of limit sliding blocks 24 to move closer to or away from each other. The two groups of limit sliding blocks 24 drive the two groups of clamping plates 25 to adjust the spacing. The user can adjust the two groups of clamping plates 25 according to the size of the workpiece. After the holding plates 25 are adjusted to a suitable spacing on both sides of the clamped workpiece, the second motor 27 is turned off, and the horizontal spacing between the two sets of clamping plates 25 is adjusted to be narrower or wider, so that the clamping component 2 can clamp and load the material as well as loosen and unload the material. The clamping component 2 cooperates with the driving action of the driving support component 1 to jointly complete the workpiece loading and unloading work of the CNC horizontal lathe. This setting is convenient for users to adjust the clamping component 2 according to specific needs, so as to realize its clamping and unloading work of objects of different sizes. The operation is simple and quick, which improves the applicability of the device.
