[0002] Machining center is a machining center machine tool, also called CNC numerical control machine tool, or machining center for short. Machining center machine tools are usually composed of control systems, servo systems, detection systems, mechanical transmission systems and other auxiliary systems. They are high-efficiency automated machine tools suitable for processing workpieces with complex shapes, and can complete multiple processes such as drilling, boring, milling, and reaming.

[0003] When a machining center clamps workpieces of different shapes or volumes, the clamping mechanism needs to be manually adjusted to adapt to the clamping and fixation of the workpiece to be processed. However, existing machining centers usually hold and fix a single workpiece on a machining platform, and the workpiece needs to be completely processed before the next workpiece can be clamped. This results in low work efficiency, and workpieces that exceed the length of the machining platform are difficult to clamp and fix. It is necessary to replace machining centers of different specifications, which is time-consuming and labor-intensive.

[0020] like Figure 1-7 As shown, a fixed block 9 is installed at the front and rear ends of the top of the fixed plate 2, and an adjusting rod 10 is installed at the opposite end of the fixed block 9, and only one group of adjusting rods 10 is a screw structure, which is threadedly connected to the movable seat 3, and the other group of adjusting rods 10 is a sliding rod structure. A driving device 11 is installed on the rear end surface of the fixed block 9 connected to the screw structure. By controlling the rotation of the threaded structure, the movable seat 3 can be controlled to move forward and backward, and then the fixed seat 4 can be controlled to move forward and backward, so that the front and rear position of the cutter head can be adjusted.

[0021] like Figure 1-7As shown, a top groove 12 is opened at the top of the fixed seat 4, and a threaded rod 13 is rotatably connected inside the top groove 12. The outer wall of the threaded rod 13 is threadedly connected to a threaded sleeve 14 fixed on the inner top of the adjusting seat 5. The rotation of the threaded rod 13 can drive the threaded sleeve 14 to move on the outer wall of the threaded rod 13, and then the left and right movement of the adjusting seat 5 can be controlled, so that the left and right position of the cutter head can be adjusted.

[0022] like Figure 1-7 As shown, a support plate 15 is installed on the top of the adjustment seat 5, and a driving device 16 is installed at the top center of the support plate 15. The output end of the driving device 16 is connected to a threaded rod 17 that passes through the top of the moving seat 6, and the bottom of the threaded rod 17 is rotatably connected to the top center of the adjustment seat 5. The rotation of the set threaded rod 17 can drive the moving seat 6 to move up and down, and then drive the up and down adjustment of the tool head, thereby realizing the adjustment of the tool head in multiple axis directions, which is convenient for all-round processing of the workpiece installed on the processing table 8.

After the two groups of processing tables 8 are successfully spliced, the set rectangular block 33 is inserted into the rectangular slot 32 to splice the two groups of threaded rods four 29. At this time, it is only necessary to rotate the handle on the left processing table 8 to drive the movement of the two groups of threaded rods four 29, thereby realizing the relative movement of the clamping plate two 31, which can not only clamp a longer workpiece, but also can be adjusted during the clamping process so that the workpiece is located in the center of the large processing platform.

[0027] Working principle: When in use, the movable seat 3 can be controlled to move forward and backward by controlling the rotation of the threaded structure, and then the forward and backward movement of the fixed seat 4 can be controlled to adjust the front and rear position of the cutter head. The rotation of the set threaded rod 13 can drive the threaded sleeve 14 to move on the outer wall of the threaded rod 13, and then the left and right movement of the adjustment seat 5 can be controlled, so that the left and right position of the cutter head can be adjusted. The rotation of the set threaded rod 2 17 can drive the movable seat 6 to move up and down, and then the up and down adjustment of the cutter head can be driven, thereby realizing the adjustment of the cutter head in multiple axis directions, which is convenient for all-round processing of the workpiece installed on the processing table 8. The rotation of the threaded rod 3 19 controlled by the handle can drive the threaded sleeve 20 to move along the outer wall of the threaded rod 2 17, and then the two sets of clamps 2 can be controlled. 1, thereby achieving clamping of workpieces of different widths, and the two sets of threaded sleeves can be driven to move toward each other by rotating the bidirectional threaded rod 23, thereby controlling the two processing tables 8 to move toward each other and thus be spliced ​​into a large processing platform. After the two sets of processing tables 8 are successfully spliced, the set rectangular block 33 is inserted into the rectangular groove 32 to splice the two sets of threaded rods four 29. At this time, it is only necessary to rotate the handle on the left processing table 8 to drive the movement of the two sets of threaded rods four 29, thereby achieving the relative movement of the clamping plate two 31, which can not only clamp workpieces with longer lengths, but also can be adjusted during the clamping process so that the workpiece is located in the center of the large processing platform, and at this time, the clamping plate one 21 can also clamp the width of the workpiece, and the clamping effect is better.
