[0026] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following description is provided in conjunction with specific examples.

[0027] The present invention will be further described in the embodiments.

[0028] The preferred embodiment of the present invention will be described below.

[0029] Please see Figures 1-5As shown, the machining tool assembly includes a worktable 1, with a support frame 2 fixedly mounted on the top of the worktable 1. A moving mechanism 4, which is fixedly connected to a connecting rod 3, is located on the top front side of the support frame 2. The function of the moving mechanism 4 is to enable the gripping mechanism 5 to move flexibly in the horizontal direction. By adjusting the position of the moving block 404, the position of the gripping mechanism 5 can be precisely controlled so as to accurately grip or place the workpiece. The connecting rod 3 is located on both sides of the support frame 2. The bottom of the moving mechanism 4 is movably connected to the gripping mechanism 5 through a telescopic adjustment rod 6. The function of the telescopic adjustment rod 6 is to enable the vertical height adjustment of the gripping mechanism 5, which helps to adapt to workpieces or processing positions of different heights and improves the flexibility and adaptability of the machine tool assembly.

[0030] The gripping mechanism 5 includes a mounting frame 501, which is located at the bottom of the telescopic adjustment rod 6. A drive assembly 502 is provided on the outer side of the mounting frame 501, and a bidirectional screw 503 is provided on the inner side of the mounting frame 501. Guide rods 504 are provided on both the front and rear sides of the bidirectional screw 503. A clamping plate 505 is provided on the opposite side of the bidirectional screw 503. A rotating shaft 507 is provided through both clamping plates 505. A gripping hand 508 that fits against the inner side of the clamping plate 505 is connected to the opposite end of the rotating shaft 507. The outer end of one rotating shaft 507 is fixedly connected to the output end of the rotating box 506.

[0031] Furthermore, the drive assembly 502 includes a drive housing 5021, a second motor 5022, a drive pulley 5023, a driven pulley 5024, a timing belt 5025, and a limiting pulley 5026. The drive housing 5021 is fixedly installed on the outside of the mounting bracket 501. The second motor 5022 is located on the top of the inner side of the mounting bracket 501, and the output end of the second motor 5022 extends through the inside of the drive housing 5021 and is connected to the drive pulley 5023. The driven pulley 5024 is connected to the outside of the drive pulley 5023 through the timing belt 5025. The limiting pulley 5026 is provided inside the drive housing 5021 and is close to the timing belt 5025.

[0032] Furthermore, one end of the bidirectional screw 503 extends into the interior of the drive box 5021 and is fixedly connected to the driven wheel 5024, and the rotation of the bidirectional screw 503 is driven by the rotation of the driven wheel 5024.

[0033] Furthermore, the gripper 508 is movably disposed on the inner surface of the clamping plate 505, and the gripper 508 fits against the surface of the clamping plate 505, facilitating the workpiece flipping operation.

[0034] Specifically, when the second motor 5022 starts, it drives the bidirectional screw 503 to rotate through the transmission of the driving wheel 5023, the synchronous belt 5025 and the driven wheel 5024. The rotation of the bidirectional screw 503 causes the two clamping plates 505 to move relative to or away from each other along their axial direction, thereby adjusting the spacing between the clamping plates 505 to accommodate workpieces of different sizes. After the clamping plates 505 clamp the workpiece, the rotating box 506 starts and drives one side of the gripper 508 to rotate through the rotating shaft 507. Due to the force during clamping, the other side of the gripper 508 will also rotate synchronously, realizing the automatic rotation of the workpiece, which greatly improves the processing efficiency, reduces manual intervention, and also reduces the processing error caused by multiple clamping and positioning.

[0035] Furthermore, support columns 7 are fixedly connected to both sides of the top of the workbench 1, and a placement table 9 and a material handling table 8 are fixedly connected to the top of the two support columns 7 respectively. The placement table 9 is used to process the workpiece to be processed, and the material handling table 8 is used to place the material to be processed.

[0036] Furthermore, the bottom of the workbench 1 is fixedly connected to four support legs 10 arranged in a rectangular array.

[0037] In another embodiment provided by this utility model, such as Figure 1 and 3 As shown, the moving mechanism 4 includes a mounting box 401, a first motor 402, a threaded rod 403, and a moving block 404. The bottom of the mounting box 401 is configured as a door, and the first motor 402 is fixedly installed on one side of the mounting box 401. The output end of the first motor 402 extends through the interior of the mounting box 401 and is connected to the threaded rod 403. The moving block 404 is threadedly connected to the outside of the threaded rod 403.

[0038] Specifically, when the first motor 402 starts, it drives the threaded rod 403 to rotate. Since the moving block 404 is threadedly connected to the threaded rod 403, when the threaded rod 403 rotates, the moving block 404 will move linearly along its axis, which is transmitted to the gripping mechanism 5 through the telescopic adjustment rod 6, so that it can move in the horizontal direction to realize the gripping and placement of the workpiece.

[0039] In use, the material to be processed is placed on the material handling platform 8, and then the first motor 402 is started. The moving mechanism 4 moves the gripping mechanism 5 above the placement platform 9. The height of the telescopic adjustment rod 6 is adjusted so that the gripping mechanism 5 is in a suitable initial position. Then the second motor 5022 is started, and the bidirectional screw 503 is driven to rotate through the drive assembly 502. The spacing of the clamping plates 505 is adjusted to clamp the workpiece. After the gripping mechanism 5 clamps the workpiece, it is moved to the processing area by the moving mechanism 4. If the workpiece needs to be flipped for multi-sided processing, the rotating box 506 is started. The workpiece is automatically flipped by the flipping of the gripper 508. Then the workpiece is placed on the placement platform 9 for processing, which improves processing efficiency, reduces manual intervention, and realizes multi-sided processing of the workpiece to be processed.
