[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figures 1-5 This utility model discloses an auxiliary pressure plate mechanism for a grooving machine, including a workbench 1 and a frame 2 mounted on the workbench 1, and further including a main pressure plate assembly 3, a reinforcing pressure plate assembly 4, a tool holder assembly 5, and a frame power assembly 6, wherein:

[0023] The workbench 1 has a guide groove 11 on one side and a positioning frame 12 on the other side, and the positioning frame 12 is welded to the workbench 1;

[0024] Please refer to the appendix. Figure 4 The main pressure plate assembly 3 includes a hydraulic cylinder 31, with a linkage frame 32 connected to the top of the hydraulic cylinder 31. Two pressure plate rods 33 are symmetrically welded to the upper end of the linkage frame 32. A pressure plate sleeve 34 is nested on the outside of the pressure plate rods 33. The pressure plate sleeve 34 is fitted with an adjusting screw 35 and rotates in coordination. Specifically, by rotating the adjusting screw 35, the adjusting screw 35 and the pressure plate rods 33 generate relative displacement through the helical force, thereby driving the pressure plate sleeve 34 to extend and retract. The length of the pressure plate can be freely adjusted according to the shape of the plate.

[0025] Please refer to the appendix. Figure 5 The reinforced pressure plate assembly 4 includes several pressure plate wheels 41. The two ends of the pressure plate wheels 41 are fitted with wheel plates 42 and rotate in cooperation. Several springs 43 are welded to the upper end of the wheel plates 42. The upper end of the springs 43 is welded with mounting bases 51. The top surface of the workbench 1 is provided with a plate 7. The plate 7 is located below the pressure plate sleeve 34. Specifically, the pressure plate wheels 41 contact the plate 7 and rotate to compress the springs 43. The springs 43 give the wheel plates 42 a reaction force, thereby causing the pressure plate wheels 41 to press on the plate 7.

[0026] The tool holder assembly 5 includes a tool holder 52, and a mounting base 51 is fixed to the bottom of the tool holder 52 by screws. Several cutting tools 53 are fixed to one side of the mounting base 51 by bolts. The tool holder 52 is fitted into the frame 2 and is slidably engaged. Specifically, when the cutting tools 53 are moved, they groove the plate 7.

[0027] In this embodiment, the rotating adjusting screw 35 can adjust the extension length of the pressure plate sleeve 34, so that the length of the pressure plate can be freely adjusted according to the shape of the plate, thereby making the plate stable and clamped under different shapes, with greater flexibility. Example 2

[0028] Based on the above embodiment 1, please refer to the appendix. Figure 2 as well as Figure 3 The workbench 1 has a working groove 13 on its side. The oil cylinder 31 is fixed in the working groove 13 by screws. The top of the working groove 13 has a through hole 14, which is penetrated by the linkage frame 32.

[0029] The top of the frame 2 is fixed with a CNC host 21, and one end of the frame 2 is provided with a guide wheel 21, and the other end is provided with a sliding guide 22.

[0030] The guide wheel 21 is fitted into the guide groove 11 and slides, and the sliding guide frame 22 is fitted into the guide rail 15 and slides. Specifically, the guide wheel 21 provides support to one end of the frame 2 and moves in cooperation with the guide groove 11.

[0031] The guide rail 15 is welded to the workbench 1 at both ends. The guide rail 15 is penetrated by the sliding guide frame 22. A limiting plate 23 is provided on one side of the guide wheel 21. The limiting plate 23 is fitted into one side of the workbench 1 and slides. Specifically, the guide rail 15 provides a support point for the sliding guide frame 22 and moves in coordination with the sliding guide frame 22. The limiting plate 23 improves the movement stability of the frame 2.

[0032] A motor 61 is located below the guide rail 15. The motor 61 is equipped with a ball screw 62. The ball screw 62 is fitted into the bottom end of the sliding guide 22 and rotates in a spiral manner. The motor 61 is electrically connected to the CNC host 21. Specifically, the ball screw 62 has less friction and adjustable clearance, which can achieve higher positioning accuracy and repeatability of the tool.

[0033] In this embodiment, the motor 61 drives the ball screw 62 to rotate. The ball screw 62 interacts with the ball sleeve at the bottom of the sliding guide 22, thereby causing the sliding guide 22 to drive the frame 22 to move longitudinally. The frame 22 then drives the tool holder 52 on it to move longitudinally.

[0034] The working principle and usage process of this utility model: When the equipment is working, firstly, one side of the plate 7 is placed against the positioning frame 12 and below the pressure plate sleeve 34. Then, according to the shape of the plate 7, the extension length of the pressure plate sleeve 34 is adjusted by rotating the adjusting screw 35. The adjusting screw 35 and the pressure plate rod 33 generate relative displacement through the spiral force, thereby driving the pressure plate sleeve 34 to extend and retract. The length of the pressure plate can be freely adjusted according to the shape of the plate, thereby achieving stable clamping of the plate and strong flexibility.

[0035] Then, the hydraulic cylinder 31 is activated to drive the linkage frame 32 to descend. The linkage frame 32 drives the pressure plate sleeve 34 to descend via the pressure plate rod 33, thereby locking the plate. Then, the relevant parameters of the plate are input through the CNC host 24. The CNC host 24 controls the motor 61 to work. The motor 61 drives the ball screw 62 to rotate. The ball screw 62 interacts with the ball sleeve at the bottom of the sliding guide 22, thereby causing the sliding guide 22 to drive the machine frame 22 to move longitudinally. The machine frame 22 drives the tool holder 52 on it to move longitudinally.

[0036] Subsequently, the tool holder 52 is brought into the grooving area. The pressure plate wheel 41 at the bottom of the mounting base 51 first contacts the plate 7 and rotates to compress the spring 43. The spring 43 gives a reaction force to the wheel plate 42, which in turn causes the pressure plate wheel 41 to press on the plate 7. At the same time, the mounting base 52 carries the tool 53 to groove the plate 7. The enhanced extrusion force achieves stable positioning of the plate 7 during grooving, preventing the plate 7 from shifting during grooving and improving the grooving quality.
