Although this provides higher movement accuracy, the hydraulic system requires reserved cylinder space and safety extension allowance, occupying a large working space. For workpieces to be pierced, screw drive is used for locking. Although the structure is simple and reduces production and usage costs, screw locking is prone to loosening when the reaction force is applied during workpiece piercing, affecting locking stability. Furthermore, when the workpiece to be pierced is long, locking only one end can easily cause bending. Utility Model Content

[0024] like Figure 1-5 As shown, the present invention proposes a split-structure piercing machine top rod trolley locking device, including a piercing machine body 1 and a support frame 2. The piercing machine body 1 includes a mounting platform 101, an L-shaped mounting bracket 102 fixed on one side of the mounting platform 101, a piercing device 103 fixed on the lower side of the top of the mounting bracket 102, a material discharge port 104 opened on the mounting platform 101, the material discharge port 104 is located directly below the piercing device 103, and is used for material discharge. The support frame 2 is fixed on one side of the mounting platform 101, and a support groove 201 is opened on the support frame 2.

[0025] like Figure 1-2As shown, it also includes a top rod mechanism 3 and an auxiliary support mechanism 5. The top rod mechanism 3 is located inside the support frame 2. The top rod mechanism 3 includes a movable frame 304, which is slidably connected to the support groove 201. The top rod mechanism 3 also includes a motor 301 and a lead screw 302. The motor 301 is fixed on the side of the support frame 2 away from the piercing machine body 1. The lead screw 302 rotatably passes through the support groove 201 and is shaft-connected to the motor 301. The lead screw 302 is vertically threaded through the bottom of the movable frame 304 to control the movement of the movable frame 304. A support is fixed inside the support groove 201. A guide rod 303 slides vertically through the bottom of the movable frame 304 to limit the movement direction of the movable frame 304. The upper part of the movable frame 304 has a square opening, and the inner side of the upper part of the movable frame 304 has a locking mechanism 4. The locking mechanism 4 includes a hydraulic cylinder 401, which is connected to a hydraulic system. The upper end of the hydraulic cylinder 401 is fixedly connected to the top of the inner side of the movable frame 304, and the lower end of the hydraulic cylinder 401 is fixedly provided with a locking block 402. The bottom of the inner side of the movable frame 304 has a locking groove 403 for locking the workpiece to be drilled.

[0026] like Figure 1-3 As shown, the movable frame 304 is provided with an auxiliary support mechanism 5 near the mounting platform 101. The auxiliary support mechanism 5 includes a connecting frame 501 and an auxiliary support block 503.

[0028] In practical use, the workpiece to be pierced is placed on the locking groove 403 in the moving frame 304. The hydraulic cylinder 401 is activated to control the locking block 402 to press down and fix the workpiece. At the same time, if the workpiece is long, the middle section can be placed on the auxiliary support block 503 for support, which plays an auxiliary support role during subsequent piercing processing, preventing the workpiece from bending due to the large piercing force of the piercing device 103. The motor 301 is activated to rotate the lead screw 302. Under the support of the support groove 201 and the guidance of the guide rod 303, the moving frame 304, which clamps one end of the workpiece through the locking mechanism 4, is moved. The piercing device 103 is activated to start the piercing operation. The metal punch can fall along the discharge port 104 for easy cleaning and collection.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
