DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] For example, see Figures 1 to 4 The utility model provides a clamping mechanism for a metal cutting device, comprising a base plate 1 and a metal plate 7, a fixing table 5 is fixedly connected to the upper surface of the base plate 1, a fixing plate 12 is fixedly connected to the upper surface of the base plate 1, a limiting frame 18 is fixedly connected to the surface of the fixing plate 12, and a cutting disc 9 is arranged below the limiting frame 18;

[0025] A slot 4 is provided on the surface of the bottom plate 1, and two symmetrically arranged moving blocks 2 are slidably connected to the inner wall of the slot 4. An L-shaped plate 17 is fixedly connected to the upper end of the moving block 2. The L-shaped plate 17 is provided with a fixing component for clamping and fixing the metal plate 7 in the horizontal direction, and the L-shaped plate 17 is also provided with auxiliary components.

[0026] The fixed component includes a motor 8 fixedly mounted on the inner wall of the slot 4, the output shaft of the motor 8 is fixedly connected with a threaded rod 19, the threaded rod 19 passes through the two moving blocks 2 and is threadedly connected thereto, the surface of the threaded rod 19 is provided with two sections of oppositely arranged threaded grooves, the surface of the L-shaped plate 17 is provided with a telescopic rod 30, the telescopic end of the telescopic rod 30 is fixedly connected with an abutment block 27, and a spring 29 is provided between the abutment block 27 and the telescopic rod 30.

[0027] The auxiliary component includes a connecting plate 16 fixedly connected to the surface of the L-shaped plate 17, the surface of the connecting plate 16 is slidably connected to a limiting rod 22, the lower end of the limiting rod 22 is fixedly connected to a hinge block 23, the surface of the hinge block 23 is hinged with a hinge plate 31, and the end of the hinge plate 31 abuts against the upper surface of the abutment block 27.

[0028] A second telescopic rod 24 is fixedly connected to the lower surface of the hinge block 23, and a second abutment block 25 is fixedly connected to the end of the telescopic rod 24. A second spring 26 is provided between the abutment block 25 and the hinge block 23. The upper end of the limit rod 22 is fixedly connected to the limit block 21.

[0029] A hydraulic component 13 is provided on the surface of the fixed plate 12, and a connecting block 14 is fixedly connected to the output end of the hydraulic component 13, and a moving block 15 is fixedly connected to the lower surface of the connecting block 14. A rectangular slot is provided on the surface of the limit frame 18 for the moving block 15 to extend and slide, and a hydraulic component 11 is fixedly installed on the lower end of the moving block 15, and a motor 10 is fixedly installed on the output end of the hydraulic component 11, and the cutting disc 9 is fixedly installed on the output shaft of the motor 10.

[0030] A cutting groove 6 is formed on the surface of the fixing platform 5 , and the cutting groove 6 is located directly below the cutting disc 9 .

[0031] More specifically, when this embodiment is used, Figure 1 , Figure 2 and Figure 3As shown, the metal sheet 7 that needs to be cut is placed on the fixed table 5, and then the motor 8 is turned on to drive the threaded rod 19 to rotate. Since the surface of the threaded rod 19 is provided with two oppositely arranged threaded grooves, the rotation of the threaded rod 19 will drive the two moving blocks 2 to move in a direction close to each other, thereby causing the two L-shaped plates 17 to move in a direction close to each other. When the abutment block 27 contacts the side of the metal sheet 7, as the L-shaped plate 17 moves, the spring 29 will be compressed, and the telescopic rod 30 will begin to shrink. Since the spring 29 is sleeved on the outside of the telescopic rod 30, under the action of the telescopic rod 30, the spring 29 can be prevented from tilting when compressed, thereby extending the service life of the spring 29. At this time, under the action of the elastic potential energy of the spring 29, the metal sheet 7 on the fixed table 5 can be clamped and fixed in the horizontal direction.

[0032] like Figure 3 As shown, when the abutment block 27 contacts the side of the metal plate 7, as the L-shaped plate 17 moves, a relative displacement will occur between the abutment block 27 and the L-shaped plate 17, that is, the abutment block 27 at this time will move to the left relative to the L-shaped plate 17. In this process, under the hinged action of the hinged plate 31, the hinge block 23 and the limit rod 22 will move downward. When the abutment block 25 contacts the upper surface of the metal plate 7, under the action of the elastic potential energy of the spring 26, the metal plate 7 can be clamped and fixed for the second time in the vertical direction. The two fixations have a good fixing effect, which avoids the problem of displacement of the metal plate 7 during the cutting operation and ensures the cutting accuracy of the metal plate 7.

[0033] It is worth noting that since the spacing between the two L-shaped plates 17 is adjustable, and as the L-shaped plate 17 moves, the abutment block 2 25 will also move synchronously therewith, when the abutment block 1 27 on the L-shaped plate 17 moves to the clamping position, the abutment block 2 25 can also move to the clamping position, so that the abutment block 1 27 and the abutment block 2 25 can meet the requirements of clamping and fixing metal plates 7 of different sizes, which is more practical.

[0034] After the metal sheet 7 is clamped and fixed, the hydraulic component 2 11 is turned on to allow the cutting disc 9 to descend to the cutting position, and then the metal sheet 7 below can be cut. By controlling the hydraulic component 1 13, the cutting disc 9 can be adjusted to different cutting positions on the surface of the metal sheet 7, so that cutting operations can be performed at multiple positions.

[0035] Embodiment 2, based on the above embodiment,

[0036] Furthermore, in order to make the abutment block 27 more stable when moving relative to the L-shaped plate 17, a slider 28 is fixedly connected to the lower surface of the abutment block 27, and a sliding groove 3 for the slider 28 to slide and adapt is provided on the surface of the L-shaped plate 17.

[0037] Under the action of the slider 28 and the slide groove 3, the contact block 27 can be limited to slide only on the L-shaped plate 17, so that the contact block 27 can be more stable when moving relative to the L-shaped plate 17.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
