DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , a fixing tool for a font cutting machine of the present invention, including a cutting table 1, a laser cutting assembly is provided above the cutting table 1, and a plurality of clamping assemblies are provided on the cutting table 1;

[0025] The clamping assembly includes a telescopic cylinder 2, a first support rod 3, a second support rod 4 and a rotating shaft 13. The telescopic cylinder 2 is fixed at the upper end of the cutting table 1. The first support rod 3 is fixed at the output end of the telescopic cylinder 2. One end of the second support rod 4 is inserted into the inside of the first support rod 3. A plurality of through holes 5 are provided on the second support rod 4. A limiting rod 6 penetrating the through hole 5 is provided at one end of the first support rod 3. A positioning seat 7 is fixedly provided at the other end of the second support rod 4. Clamping rods 8 are hinged on both sides of the positioning seat 7. A clamping block 9 is fixedly provided at the end of the clamping rod 8 away from the positioning seat 7. A positioning shaft 12 is rotatably provided in the middle part of the clamping rod 8. A positioning ring 10 is fixedly provided at the top of the positioning shaft 12. Two screws 14 penetrating the positioning ring 10 are symmetrically provided on the rotating shaft 13. The two screws 14 are of reverse thread structure;

[0026] In this embodiment, the laser cutting assembly adopts an existing structure, and its principle does not need to be described in detail here;

[0027] Through a plurality of clamping assemblies, the workpiece on the cutting table 1 can be positioned and clamped. During this process, by starting the telescopic cylinder 2, the first support rod 3 can drive the second support rod 4 to move, so that the two clamping rods 8 can drive the clamping block 9 to clamp and position the workpiece on the cutting table 1;

[0028] When positioning workpieces of different batches of plates, pull out the limiting rod 6, and then pull the second support rod 4, so as to greatly adjust the positions of the positioning seat 7 and the clamping rod 8. Further rotate the rotating shaft 13. Due to the action of the reverse thread structure, the two positioning rings 10 can move synchronously and in opposite directions on the two screws 14. Since the positioning shaft 12 can rotate on the clamping rod 8, the opening and closing degrees of the two clamping rods 8 can be temporarily adjusted, and then the position of the clamping block 9 can be finely adjusted. When clamping plates of different sizes, it is not necessary to program the cylinder to adjust the parameters of the cylinder. The structure is simple and the operation is convenient.

[0029] Furthermore, a toggle block is provided at one end of the rotating shaft 13 to facilitate the operation of the rotating shaft 13 .

[0030] Furthermore, a fixing seat 11 is rotatably provided at the lower end of the positioning shaft 12, and the fixing seat 11 is fixed to the upper end of the clamping rod 8. The fixing seat 11 is fixed to the upper end of the clamping rod 8 by screws, and the screw fixing method can facilitate the assembly of the positioning ring 10.

[0031] Furthermore, the clamping block 9 is a cylindrical structure, and the second support rod 4 and the first support rod 3 are both rectangular structures.

[0032] Furthermore, the limiting rod 6 is threadedly connected to the through hole 5, so that the limiting rod 6 can be installed more firmly.
