DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Embodiment: As Figures 1-5As shown in the figure, the utility model provides a high-efficiency wire feeding machine combined pressure wheel, which includes a rotating shaft 1. A hub 11 is detachably arranged on the outer side of the rotating shaft 1. One end of the rotating shaft 1 is provided with a clamping groove 12, and a triangular groove 13 is arranged inside the clamping groove 12. Symmetrically distributed clamping blocks 14 are arranged inside the clamping groove 12. On the mutually remote sides of the two clamping blocks 14, stabilizing rods 15 are fixedly installed respectively. Uniformly distributed stabilizing holes 16 are arranged on the inner wall of the clamping groove 12, and multiple stabilizing rods 15 are respectively movably clamped in the corresponding stabilizing holes 16. On the mutually remote sides of the two clamping blocks 14, symmetrically distributed first springs 17 are fixedly installed respectively. The other ends of the first springs 17 are fixedly connected with the inner wall of the clamping groove 12. A positioning block 18 is movably arranged at one end of the hub 11. A triangular block 19 is fixedly installed on the outer side of the positioning block 18. The triangular block 19 is movably clamped in the triangular groove 13. A positioning groove 191 is arranged on the outer side of the positioning block 18, and the clamping block 14 is used in cooperation with the positioning groove 191.

[0019] A cavity 2 is arranged on the outer side of the positioning block 18. Symmetrically distributed push plates 21 are movably arranged inside the cavity 2, and the push plates 21 are used in cooperation with the clamping blocks 14.

[0020] On the mutually remote sides of the two push plates 21, symmetrically distributed second springs 3 are fixedly installed respectively. The other ends of the multiple second springs 3 are fixedly connected with the inner wall of the cavity 2. By arranging the second springs 3, the push plates 21 can automatically reset after use, improving the use experience of the staff.

[0021] Symmetrically distributed limiting rods 4 are fixedly installed inside the cavity 2. Both of the two limiting rods 4 penetrate through the two push plates 21. By arranging the limiting rods 4, the push plates 21 move more stably.

[0022] A fixing plate 5 is fixedly installed on the outer side of the positioning block 18. Symmetrically distributed third springs 51 are fixedly installed on the side of the fixing plate 5 close to the hub 11. The other ends of the third springs 51 are fixedly connected with the hub 11. By arranging the fixing plate 5 and the third springs 51, after the clamping block 14 disengages from the positioning groove 191, the positioning block 18 can automatically withdraw from the clamping groove 12 under the action of the third spring 51.

[0023] Uniformly distributed clamping rods 6 are fixedly installed on the outer side of the rotating shaft 1. Annularly distributed limiting grooves 61 are arranged inside the hub 11. The clamping rods 6 are movably clamped in the limiting grooves 61. By arranging the clamping rods 6 and the limiting grooves 61, the rotating shaft 1 can better drive the hub 11 to rotate.

[0024] The number of both the clamping rods 6 and the limiting grooves 61 is six, improving the connection stability between the rotating shaft 1 and the hub 11.

[0025] On the sides of the two clamping blocks 14 away from the triangular groove 13, they are both distributed in an inclined state, enabling the triangular block 19 to better push open the two clamping blocks 14.

[0026] Working principle: During actual use, the hub 11 is moved towards the rotating shaft 1 until the positioning block 18 and the triangular block 19 enter the clamping groove 12. At this time, the triangular block 19 comes into contact with the two clamping blocks 14 and gradually exerts a pushing force on the clamping blocks 14, causing the two clamping blocks 14 to move away from each other and exert a pressure on the first spring 17 to deform it. The movement direction of the clamping blocks 14 is limited by the provided stabilizing rod 15 and stabilizing holes 16. When the positioning block 18 drives the positioning groove 191 to move to the designated position, the first spring 17 releases its elastic force, driving the two clamping blocks 14 to move towards each other until the clamping blocks 14 are clamped into the positioning groove 191, completing the installation of the positioning block 18 and the hub 11; when it is desired to disassemble the hub 11, by pushing the push plate 21 to move, the push plate 21 pushes the clamping block 14 to move until the clamping block 14 is pushed out of the positioning groove 191, and then the positioning block 18 is withdrawn from the clamping groove 12, completing the disassembly of the hub 11.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
