The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] A quick positioning and clamping device for parts of CNC machine tools is disclosed in the Chinese utility model patent application with the public specification CN208744243U. Although the clamping seat can be expanded outward, the positioning effect is good and the processing efficiency of the parts is improved, the range of the clamped parts is relatively single during use and the clamping effect is not stable enough. Therefore, a quick clamping device for parts of CNC machine tools is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a quick clamping device for parts of a numerically controlled machine tool to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, a guide rod is fixedly arranged inside the threaded groove below the threaded rod, and the guide rod is movably connected to the movable plate;

[0009] Preferably, the fixing mechanism comprises a movable rod, a counterweight slot, a support rod, a counterweight block and an insert plate, the movable rod is movably arranged inside the movable slot, a counterweight slot is provided on one side inside the movable slot, a support rod is fixedly arranged inside the counterweight slot, a counterweight block is movably arranged on the outer side of the support rod, one side of the movable rod is fixedly connected to the counterweight block through a connecting block, and an insert plate is fixedly arranged on the bottom end of the movable rod;

[0010] Preferably, the top end of the movable rod passes through the movable slot on the outside of the clamping plate, and a handle is fixedly provided on one end of the movable rod located on the outside of the clamping plate;

[0011] Preferably, the matching mechanism includes a fixed block, a through groove and a mounting plate, the fixed block is arranged inside the fixed groove, a through groove is opened inside the fixed block, a mounting plate is fixedly arranged on one side of the fixed block, and one side of the mounting plate is arranged in an arc shape.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By starting the driving motor, the threaded rod is driven to rotate. At this time, under the action of the guide rod, the movable plate can be moved horizontally along the surface of the threaded rod. Because the threads at both ends of the threaded rod are set in opposite directions, the movable plates at both ends can be moved in opposite directions, thereby driving the clamping plate at the top to move until the mounting plates at both ends contact the machine tool parts, and then stop the rotation of the driving motor. This setting can effectively and quickly clamp the machine tool parts and keep the parts stable on the workbench surface. Under the setting of the threaded rod and the movable plate, the clamping force of the clamping plate can be effectively maintained, thereby improving practicality.

[0014] 2. By pulling the handle upward, the movable rod is driven to move upward. When the manpower is greater than the gravity of the counterweight block, the plug plate at the bottom of the movable rod can be driven to move up until the plug plate leaves the through slot, thereby canceling the fixing effect between the fixed block and the clamping plate. This setting facilitates the replacement operation of the mounting plate, so that it can be replaced according to different types of machine tool parts. The matching mounting plate increases the contact area between the mounting plate and the machine tool parts, improves the stability of the clamping, and enhances the overall applicability of the equipment.

[0025] Through the above scheme, the moving distance of the movable plate 8 can be controlled, and because the threads at both ends of the threaded rod 7 are arranged in opposite directions, the movable plates 8 at both ends can be moved in opposite directions, and the movable plate 8 can drive the clamping plate 3 to move accordingly, thereby achieving a clamping effect;

[0026] In this embodiment, preferably, a guide rod 9 is fixedly arranged inside the thread groove 2 below the thread rod 7, and the guide rod 9 is movably connected to the movable plate 8;

[0027] Through the above scheme, the movable plate 8 plays a limiting and guiding role, so that the movable plate 8 can move horizontally along the surface of the threaded rod 7;

[0028] In this embodiment, preferably, the fixing mechanism includes a movable rod 10, a counterweight slot 11, a support rod 12, a counterweight block 13 and an insert plate 14, the movable rod 10 is movably arranged inside the movable slot 5, a counterweight slot 11 is opened on one side inside the movable slot 5, a support rod 12 is fixedly arranged inside the counterweight slot 11, a counterweight block 13 is movably arranged on the outer side of the support rod 12, one side of the movable rod 10 is fixedly connected to the counterweight block 13 through a connecting block, and an insert plate 14 is fixedly arranged at the bottom end of the movable rod 10;

[0029] Through the above scheme, under the action of the support rod 12, the counterweight block 13 can be supported and limited, and under the action of the counterweight block 13, the counterweight block 13 can be vertically moved up and down along the surface of the support rod 12, thereby driving the insert plate 14 to move down and insert into the through slot 17 of the fixing block 16, forming a fixing effect;

[0030] In this embodiment, preferably, the top end of the movable rod 10 passes through the movable slot 5 and is outside the clamping plate 3, and a handle 15 is fixedly provided at one end of the movable rod 10 located outside the clamping plate 3;

[0031] Through the above solution, by pulling the handle 15 upward, the moving distance of the movable rod 10 can be effectively controlled, thereby controlling the moving distance of the plug board 14, and achieving control of the fixing effect;

[0032] In this embodiment, preferably, the matching mechanism includes a fixing block 16, a through slot 17 and a mounting plate 18, the fixing slot 4 is provided with a fixing block 16, the fixing block 16 is provided with a through slot 17, one side of the fixing block 16 is fixedly provided with a mounting plate 18, and one side of the mounting plate 18 is arranged in an arc shape;

[0034] The present embodiment is a CNC machine tool parts quick clamping device which starts the driving motor 6 to drive the threaded rod 7 to rotate. At this time, under the action of the guide rod 9, the movable plate 8 can be moved horizontally along the surface of the threaded rod 7. Because the threads at both ends of the threaded rod 7 are arranged in opposite directions, the movable plates 8 at both ends can be moved in opposite directions, thereby driving the clamping plate 3 at the top to move accordingly, until the mounting plates 18 at both ends contact the machine tool parts, and then the rotation of the driving motor 6 is stopped. This arrangement can effectively and quickly clamp the machine tool parts and keep the parts stable on the surface of the workbench 1. Moreover, under the arrangement of the threaded rod 7 and the movable plate 8, the clamping force of the clamping plate 3 can be effectively maintained, thereby improving practicality.

[0035] By pulling the handle 15 upward, the movable rod 10 is driven to move upward. When the manpower is greater than the gravity of the counterweight block 13, the plug plate 14 at the bottom end of the movable rod 10 can be driven to move upward until the plug plate 14 leaves the through groove 17, and the fixing effect between the fixing block 16 and the clamping plate 3 is cancelled. This setting facilitates the replacement operation of the mounting plate 18, so that it can be replaced according to different types of machine tool parts. Matching mounting plates 18 increase the contact area between the mounting plate 18 and the machine tool parts, improve the stability of clamping, and enhance the overall applicability of the equipment.
