[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. 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;

[0003] A Chinese patent publication (publication number: CN217095392U) discloses a feeding device for a CNC machine tool, which includes a base, a baffle plate is fixedly connected to the left side of the upper surface of the base, a stepper motor is fixedly connected to the left front of the baffle plate, a driving screw is fixedly connected to the output end of the stepper motor, a moving plate is threadedly connected to the middle of the driving screw, a fastening screw is rotatably connected to the left rear side of the upper surface of the moving plate, a pressure strip is threadedly connected to the middle of the fastening screw, a clamping assembly is installed on the front and rear sides of the upper surface of the moving plate, the clamping assembly includes a support plate, the bottom of the support plate is fixedly connected to the upper surface of the moving plate, the left and right sides of the front of the support plate are fixedly connected to limit rods, the front end of the limit rod is slidably connected to the clamping plate, the top of the clamping plate is fixedly connected to a top plate, and the top plate is rotatably connected to a guide roller. The utility model is provided with a stepping motor, a fastening screw and a pressure strip, so that the material can be automatically fed and the accuracy of the punching spacing is maintained within a reasonable range. However, during use, only the iron bars below the length of the driving screw can be fed. For the iron bars exceeding the length of the driving screw, after the driving screw drives the moving driving screw to move the maximum stroke of the driving screw, the remaining part of the iron bar needs to be manually operated by the clamping assembly to release the fixation of the iron bar, and then the driving screw brings the clamping assembly back to the initial end of the driving screw, and then the iron bar is clamped and fixed by manually operating the clamping assembly, and then the iron bar is driven to move by the driving screw to process the remaining iron bar. If the length of the iron bar is long, this method is extremely time-consuming and labor-intensive, which greatly reduces the feeding efficiency and is not conducive to the subsequent processing operation of the CNC machine tool. Therefore, a feeding device for a CNC machine tool is proposed. Utility Model Content

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides a feeding device for a CNC machine tool, comprising a base plate 1, a punching mechanism 2, a feeding mechanism 3, a guide mechanism 4 and an iron bar 5;

[0025] The punching mechanism 2 is mounted on the bottom plate 1, the feeding mechanism 3 is mounted on the bottom plate 1 and located on one side of the punching mechanism 2, and the guide mechanism 4 is mounted on the bottom plate 1 and located on the side where the punching mechanism 2 and the feeding mechanism 3 repel each other;

[0026] The feeding mechanism 3 also includes a feeding plate 31, which is located above the base plate 1. A threaded hole 32 is provided on one side of the feeding plate 31, and a threaded rod 34 is threadedly connected to the inner wall of the threaded hole 32. A motor 35 is installed on the upper surface of the base plate 1, and the output end of the motor 35 is fixedly connected to one end of the threaded rod 34. Two first electric push rods 36 are symmetrically installed on the upper surface of the feeding plate 31, and the telescopic ends of the two first electric push rods 36 are both installed with second electric push rods 37, and the telescopic ends of the two second electric push rods 37 are both fixedly connected with a clamping plate 38, and the iron bar 5 is placed on the feeding plate 31.

[0027] In one embodiment, two through holes 33 are symmetrically opened on one side of the feeding plate 31, and the inner side walls of the two through holes 33 are slidably connected with guide rods 6, and one end of the two guide rods 6 is fixedly connected with a third fixing plate 7, and the bottom of the third fixing plate 7 is fixedly connected to the upper surface of the base plate 1; by setting the guide rod 6, the position of the feeding plate 31 is restricted, so that when the threaded rod 34 rotates in the threaded hole 32 on the feeding plate 31, it only drives the feeding plate 31 to move horizontally without rotating.

[0028] In one embodiment, one end of the two guide rods 6 close to the stamping mechanism 2 is fixedly connected to a fourth fixed plate 8, one end of the threaded rod 34 is rotatably connected to the fourth fixed plate 8 through a bearing, and the bottom of the fourth fixed plate 8 is fixedly connected to the upper surface of the base plate 1; by setting the fourth fixed plate 8, the position of the feeding plate 31 is restricted, and at the same time, the stability of the threaded rod 34 and the guide rod 6 is improved.

[0029] In one embodiment, the guide mechanism 4 also includes two first fixed plates 41, the bottoms of the two first fixed plates 41 are fixedly connected to the upper surface of the base plate 1, the adjacent sides of the two first fixed plates 41 are fixedly connected with a sleeve 42, the inner wall of the sleeve 42 is slidably connected with a rod body 44, one end of the rod body 44 is fixedly connected with a U-shaped plate 45, and the inner wall of the U-shaped plate 45 is rotatably connected with a first guide roller 46; through the setting of the first guide roller 46, the iron bar 5 is located between the two first guide rollers 46, the position of the iron bar 5 is limited, and the stability of the iron bar 5 is improved.

[0030] In one embodiment, one end of the rod body 44 is fixedly connected to a spring 43, and one end of the spring 43 is fixedly connected to the first fixed plate 41; through the setting of the spring 43, when the iron bar 5 is placed between the two first guide rollers 46, the width of the iron bar 5 squeezes the two first guide rollers 46, the first guide rollers 46 squeeze the rod body 44, and the rod body 44 squeezes the spring 43. The reverse thrust of the spring 43 causes the first guide rollers 46 to clamp the iron bar 5, thereby improving the stability of the iron bar 5.

[0031] In one embodiment, two second fixing plates 47 are symmetrically fixedly connected to the upper surface of the bottom plate 1, and second guide rollers 48 are rotatably connected to adjacent sides of the two second fixing plates 47; the processed iron bars 5 are guided by the second guide rollers 48.

[0032] When the utility model is working, firstly, one end of the iron bar 5 is inserted between the two first guide rollers 46, and the first guide roller 46 cooperates with the spring 43 to clamp the iron bar 5, so as to improve the stability of the iron bar 5, and then the first electric push rod 36 is started to drive the second electric push rod 37 and the clamping plate 38 to move until one end of the iron bar 5 is located between the two clamping plates 38, and the second electric push rod 37 is started to drive the clamping plate 38 to clamp and fix the iron bar 5, and then the first electric push rod 36 retracts according to the punching distance, pulls the iron bar 5, and the stamping mechanism 2 performs stamping processing on the iron bar 5. After stamping, the second electric push rod 36 is started to drive the clamping plate 38 to clamp and fix the iron bar 5. The movable push rod 37 drives the clamping plate 38 to loosen the clamping of the iron bar 5, and then the first electric push rod 36 extends out, driving the second electric push rod 37 and the clamping plate 38 to move again, the second electric push rod 37 drives the clamping plate 38 to clamp the iron bar 5, the first electric push rod 36 retracts according to the punching distance, pulls the iron bar 5, and the stamping mechanism 2 stamps the iron bar 5. Similarly, the iron bar 5 is continuously fed. When the punching distance is large, greater than the stroke of the first electric push rod 36, the motor 35 can be started to drive the feeding plate 31 to move, thereby increasing the moving distance of the second electric push rod 37 and the clamping plate 38.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
