DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3 A feeding device for a CNC machine tool comprises a base 1 arranged between a feeding platform and a bed, and a self-locking moving wheel is provided on the base 1, and the base 1 is moved between the feeding platform and the bed by the self-locking moving wheel;

[0021] The base 1 is provided with a receiving platform 2 corresponding to the feeding platform and used to receive the workpiece, and the base 1 is provided with an adjustment component for adjusting the height of the receiving platform 2;

[0022] The adjustment assembly includes a sleeve 4 fixedly mounted on the base 1, and a moving rod 5 is slidably sleeved in the sleeve 4, the material receiving platform 2 is arranged on the moving rod 5, and a symmetrically arranged slider 8 is slidably sleeved on the base 1, and a connecting rod 9 is connected between the slider 8 and the moving rod 5. A telescopic rod 10 connected to the slider 8 is fixedly mounted on the base 1. The sleeve 4 guides the moving rod 5 so that the moving rod 5 can smoothly pull the material receiving platform 2 when moving;

[0023] The receiving platform 2 and the moving rod 5 extend to the upper end position outside the sleeve 4. The sleeve 4 is provided with a long hole for guiding the connecting rod 9. The long hole guides the connecting rod 9 so that the connecting rod 9 can smoothly pull the moving rod 5 when moving, and the two ends of the connecting rod 9 are respectively connected to the slider 8 and the moving rod 5 with a pin. The receiving platform 2 is a circular structure with openings on the top and side, and the receiving platform 2 is provided with an inclined pad 6 and a blanking plate 7 corresponding to the workpiece. The inclined pad 6 can cushion the falling workpiece, and the blanking plate 7 allows the material to fall independently when rotating;

[0024] The output end of the telescopic rod 10 contracts and drives the slider 8 to slide on the base 1. When the slider 8 moves, it pulls the moving rod 5 through the connecting rod 9. When the moving rod 5 moves, it drives the receiving platform 2 to move up and down, so that the receiving platform 2 can be located below the feeding platform, thereby preventing the workpiece from colliding during unloading and allowing the workpiece to fall smoothly.

[0025] The base 1 is provided with a material unloading platform 3 extending to the bed and used for unloading materials, and the base 1 is provided with an adjustment component for adjusting the height of the material unloading platform 3;

[0026] The adjustment assembly includes a bracket 11 fixedly mounted on the base 1, and a guide rod 12 is fixedly mounted on the bracket 11, a rack 13 is provided on the guide rod 12 in a sliding sleeve, the unloading platform 3 is provided on the rack 13, a motor 14 is fixedly mounted on the bracket 11, and the output end of the motor 14 is fixedly connected to a rotating shaft 15 that is transmission-connected to the rack 13, the guide rod 12 guides the rack 13, and enables the rack 13 to smoothly pull the unloading platform 3 when moving;

[0027] The unloading platform 3 and the rack 13 extend to the upper end position outside the bracket 11. The unloading platform 3 is a concave structure. The rotating shaft 15 is horizontally arranged, and a gear 16 connected to the rack 13 is fixedly installed on the rotating shaft 15.

[0028] The output end of the motor 14 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the gear 16 to pull the meshing rack 13. When the rack 13 moves, it drives the unloading platform 3 to move to a position above the bed, so that the unloading platform 3 can fit with the bed, and the height of the connecting platform 2 is adjusted so that the height of the connecting platform 2 is the same as that of the unloading platform 3;

[0029] The unloading table 3 is provided with a limiting structure for clamping and limiting the workpiece;

[0030] The limiting structure includes a second motor 17 fixedly mounted on the unloading platform 3, and the output end of the second motor 17 is fixedly connected to a screw rod 18, a matching nut 19 is provided on the sliding sleeve of the screw rod 18, and a second telescopic rod 20 is fixedly mounted on the nut 19, and a contact plate 21 that resists the movement of the workpiece is fixedly mounted on the second telescopic rod 20. The screw rod 18 is horizontally arranged on both sides of the unloading platform 3;

[0031] After the output end of the telescopic rod 20 is extended, it drives the contact plate 21 to clamp the workpiece from both sides, and the contact plate 21 is driven by the motor 17 to move the workpiece, thereby enabling the workpiece to move onto the bed, so that the workpiece can move smoothly during movement;

[0032] It should be noted that the specific models and specifications of telescopic rod 10, motor 14, motor 2 17, and telescopic rod 20 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0033] The functional principle of this utility model can be explained through the following operation modes:

[0034] Move the base 1 between the feeding platform and the bed through the self-locking moving wheels;

[0035] The output end of the telescopic rod 10 contracts and drives the slider 8 to slide in the base 1. The slider 8 pulls the connecting rod 9 when sliding. The position difference generated when the connecting rod 9 deflects in the long hole can resist the moving rod 5, so that the moving rod 5 drives the receiving platform 2 to move upward when sliding in the sleeve 4. After the receiving platform 2 moves upward, it can move to a position below the feeding platform;

[0036] The conveyor table conveys the workpieces to the inclined pad 6, so that the workpieces are accumulated in the receiving table 2;

[0037] The output end of the motor 14 drives the shaft 15 to rotate, and the shaft 15 drives the gear 16 to pull the meshing rack 13. When the rack 13 slides on the guide rod 12, the unloading platform 3 is moved to a position above the bed;

[0038] The output end of the telescopic rod 10 is extended and retracted to move the receiving platform 2 downward, so that the receiving platform 2 and the unloading platform 3 are at the same height;

[0039] The blanking plate 7 rotates to allow the workpiece to fall independently, and the workpiece falls from the receiving platform 2 to the blanking platform 3;

[0040] The output end of the telescopic rod 20 is extended and retracted to drive the contact plate 21 to clamp the workpiece from both sides;

[0041] The output end of the second motor 17 drives the screw 18 to rotate. When the screw 18 rotates, it drives the nut 19 to move horizontally, so that the nut 19 drives the contact plate 21 to move onto the bed. The operator removes the workpiece and places it in the bed for processing.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
