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 of the embodiments.

[0020] Reference Figure 1-Figure 3 A feeding bracket fixture for a laser tube cutting machine comprises a bracket base 1, a support frame 2 is fixedly mounted on the bracket base 1, a feeding roller 3 is rotatably mounted on the bracket base 1, mounting columns 4 are symmetrically fixedly mounted on the base 1, two mounting columns 4 are located on both sides of the feeding roller 3, and a clamping assembly for clamping a pipe is provided on the two mounting columns 4. The clamping assembly comprises a cross bar 12 slidably mounted between the two mounting columns 4 through an elastic component, two moving blocks 13 symmetrically slidably mounted on the cross bar 12 through potential energy components, two top blocks 14 respectively fixedly mounted on the two moving blocks 13, and two rolling balls 15 respectively mounted on the two moving blocks 13, and the moving blocks 14 are fixedly mounted on the two moving blocks 13. A spherical groove is provided on the surface of the moving block 13, and the ball 15 is rolled and embedded in the spherical groove. The feeding roller 3 is located directly below the two balls 15. The adjacent sides of the two mounting columns 4 are provided with lifting grooves. The elastic component includes two lifting blocks 16 respectively slidably installed in the two lifting grooves and two first telescopic springs 17 respectively fixedly installed on the two lifting blocks 16. The cross bar 12 is horizontally fixedly installed on the two lifting blocks 16. One end of the first telescopic spring 17 is fixedly connected to the inner wall of the lifting groove. The potential energy component includes a second telescopic spring 18 sleeved on the cross bar 12. The two ends of the second telescopic spring 18 are respectively fixedly connected to the moving block 13 and the lifting block 16.

[0021] The metal tube is placed on the support frame 2 and the feeding roller 3. Under the action of the elastic force of the first telescopic spring 17, the lifting block 16 tends to move vertically downward, so that the cross bar 12 is driven to move vertically downward, and then under the action of the elastic force of the second telescopic spring 18, the two moving blocks 13 are driven to move relative to each other. Under the mutual cooperation of the first telescopic spring 17 and the second telescopic spring 18, the two rolling balls 15 contact the top of the metal tube, so that the metal tube is fixedly clamped between the two rolling balls 15 and the feeding roller 3, which can be used to clamp metal tubes of different thicknesses. When the feeding roller 3 rotates, it can drive the metal tube to move horizontally to achieve feeding.

[0022] A moving plate 5 is slidably mounted on the bracket base 1 through an elastic component, a positioning plate 6 is fixedly mounted on the moving plate 5, a first spring rod 7 is symmetrically fixedly mounted on one end of the moving plate 5, a moving seat 8 is fixedly mounted on one end of two first spring rods 7, a driving wheel 9 is rotatably mounted on the moving seat 8 through a rotating shaft, a driving motor 10 is fixedly mounted on the moving seat 8, and an output shaft of the driving motor 10 is fixedly connected to the rotating shaft on the driving wheel 9. The elastic component includes two second spring rods 11 symmetrically fixedly mounted on both side surfaces of the moving plate 5, one end of the two second spring rods 11 are fixedly connected to the bracket base 1, and the elastic coefficient of the second spring rod 11 is greater than the elastic coefficient of the first spring rod 7;

[0023] The first spring rod 7 is in a compressed state, and the movable seat 8 is moved closer to the feeding roller 3 under the action of the elastic force of the first spring rod 7, so that the driving wheel 9 contacts the feeding roller 3, and the driving motor 10 drives the driving wheel 9 to rotate. Under the action of the friction between the driving wheel 9 and the feeding roller 3, the feeding roller 3 is driven to rotate. After the metal tube is loaded, one end will contact the positioning plate 6, and the movable plate 5 will be driven to move on the bracket base 1 through the positioning plate 6. The second spring rod 11 is compressed. At this time, the first spring rod 7 will be extended due to the movement of the movable plate 5, and the elastic force component of the first spring rod 7 will be reduced, so that the friction between the driving wheel 9 and the feeding roller 3 will also be reduced, until the friction is not enough to drive the feeding roller 3 to rotate, and the loading is stopped at this time. During the entire loading process, there is no need for manual operation by the staff, the operation is convenient, and the work intensity of the staff is effectively reduced.

[0024] A resistance sleeve is provided on the feeding roller 3, and the resistance sleeve is made of rubber. The resistance sleeve can increase the friction between the feeding roller 3 and the driving wheel 9 to avoid slipping between them when the driving wheel 9 drives the feeding roller 3 to rotate.

[0025] In the utility model, when loading, the driving wheel 9 drives the loading roller 3 to rotate until one end of the metal tube contacts the positioning plate 6, thereby driving the movable plate 5 to move. When the movable plate 5 moves, the elastic force of the first spring rod 7 will decrease, so that the friction between the driving wheel 9 and the loading roller 3 will also decrease, until the friction is insufficient to drive the loading roller 3 to rotate. At this time, the loading is stopped. During the whole loading process, there is no need for manual operation by the staff, the operation is convenient, and the work intensity of the staff is effectively reduced.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
