Specific Embodiments
[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] Please refer to Figures 1 - 4 , the present invention provides a cutting device for processing valve pockets, including a support frame 1. An electric telescopic rod 2 is provided on the outer wall of the top end of the support frame 1. By starting the electric telescopic rod 2, it drives the square plate 3 to move vertically. The outer wall of the electric telescopic rod 2 is fixedly connected with the square plate 3. Through the square plate 3, the cutting knife 4 is supported and fixed. A T-shaped groove 13 is opened on the outer wall of the square plate 3. The cutting knife 4 is slidably connected to the inner wall of the T-shaped groove 13. By sliding the cutting knife 4 along the inner wall of the T-shaped groove 13, the position of the cutting knife 4 is adjusted to change the cutting size of the valve pocket.
[0027] A pull rod 7 is fixedly connected to the outer wall of the cutting knife 4. The outer wall of the pull rod 7 penetrates and is slidably connected to the inner wall of the square plate 3. By sliding the pull rod 7 along the inner wall of the square plate 3, the cutting knife 4 is driven to slide along the inner wall of the T-shaped groove 13. A clamping groove 8 is formed on the outer wall of the pull rod 7. By providing multiple groups of clamping grooves 8, the clamping block 15 is clamped with the clamping groove 8 at different positions, so as to limit the pull rod 7 at different positions. A square block 12 is fixedly connected to the outer wall of the square plate 3. A clamping block 15 is elastically connected to the inner wall of the square block 12 through a limiting spring 14. Due to the elastic force of the limiting spring 14, the clamping block 15 always maintains the clamping effect with the clamping groove 8 without external force, so as to limit the pull rod 7.
[0028] A square groove 9 is formed on the outer wall of the support frame 1. A pressure rod 5 is slidably connected to the inner wall of the square groove 9. By sliding the pressure rod 5 along the inner wall of the square groove 9, the pressure rod 5 presses and fixes or releases the pressing and fixing effect on the valve pocket. A connecting rod 6 is fixedly connected to the outer wall of the pressure rod 5. Through the connecting rod 6, two groups of pressure rods 5 are simultaneously driven to slide along the inner wall of the square groove 9. The inner wall of the connecting rod 6 penetrates and is slidably connected to a handle 16. Through the handle 16, it is convenient for the staff to slide the connecting rod 6.
[0029] One end of the limiting spring 14 is fixedly connected to the inner wall of the square block 12, and the other end of the limiting spring 14 is fixedly connected to the outer wall of the clamping block 15. Due to the fixed connection effect of the limiting spring 14 with the square block 12 and the clamping block 15, the clamping block 15 is kept fixed, preventing the clamping block 15 from falling off and affecting the clamping effect between the clamping block 15 and the clamping groove 8. A sliding groove 10 is formed on the outer wall of the support frame 1. The outer wall of the connecting rod 6 is slidably connected to the inner wall of the sliding groove 10. By sliding the connecting rod 6 along the inner wall of the sliding groove 10, the pressure rod 5 is driven to slide along the inner wall of the square groove 9.
[0030] The outer wall of the clamping block 15 is slidably connected to the inner wall of the square block 12. By sliding the clamping block 15 along the inner wall of the square block 12, the clamping block 15 is clamped or unclamped with the clamping groove 8. The outer wall of the clamping block 15 is clamped with the inner wall of the clamping groove 8. Due to the clamping effect between the clamping block 15 and the clamping groove 8, the square block 12 limits the pull rod 7. A limiting groove 11 is formed on the outer wall of the support frame 1. A limiting block 18 is elastically connected to the inner wall of the connecting rod 6 through a compression spring 17. Due to the elastic force of the compression spring 17, the limiting block 18 always maintains the clamping effect with the limiting groove 11 without external force, so as to limit the connecting rod 6. The outer wall of the limiting block 18 is fixedly connected to the outer wall of the handle 16. By sliding the handle 16 along the inner wall of the connecting rod 6, the limiting block 18 is driven to slide along the inner wall of the connecting rod 6.
[0031] One end of the compression spring 17 is fixedly connected to the inner wall of the connecting rod 6, and the other end of the compression spring 17 is fixedly connected to the outer wall of the limit block 18. Through the fixed connection effect of the compression spring 17 with the connecting rod 6 and the limit block 18, the limit block 18 is kept fixed, preventing the limit block 18 from falling off and affecting the clamping effect between the limit block 18 and the limit groove 11. The outer wall of the limit block 18 is slidably connected to the inner wall of the connecting rod 6. By sliding the limit block 18 along the inner wall of the connecting rod 6, the limit block 18 is clamped or unclamped with the limit groove 11. The outer wall of the limit block 18 is clamped with the inner wall of the limit groove 11. Through the clamping effect between the limit block 18 and the limit groove 11, the support frame 1 limits the connecting rod 6.
[0032] In the present utility model, during use, by a worker pulling the handle 16, the limit block 18 is driven to slide rightward along the inner wall of the connecting rod 6 by the handle 16, so that the clamping effect between the limit block 18 and the limit groove 11 is released, and at the same time the limiting effect of the connecting rod 6 on the support frame 1 is released. By the worker sliding upward along the inner wall of the chute 10, the pressing rod 5 is driven to slide upward along the inner wall of the square groove 9. The handle 16 is loosened, so that the limit block 18 is clamped with the higher limit groove 11 under the elastic force of the compression spring 17, enabling the support frame 1 to limit the connecting rod 6, and at the same time keeping the pressing rod 5 in a raised state.
[0033] By a worker placing the valve pocket below the two pressing rods 5, pulling the handle 16, and sliding the connecting rod 6 downward along the inner wall of the chute 10, the pressing rod 5 is driven to slide downward along the inner wall of the square groove 9 by the connecting rod 6, so that the pressing rod 5 presses and fixes the valve pocket. By loosening the handle 16, the limit block 18 is clamped with the lower limit groove 11, keeping the pressing rod 5 pressing the valve pocket. By starting the electric telescopic rod 2, the square plate 3 is driven to move downward, and at the same time the cutting knife 4 is driven to move downward. The valve pocket is cut by the cutting knife 4.
[0034] When it is necessary to change the cutting size of the valve pocket, by a worker pulling the block 15 rightward, the clamping effect between the block 15 and the slot 8 is released, and at the same time the limiting effect of the square plate 3 on the pull rod 7 is released. By the worker pulling or pushing the pull rod 7, the cutting knife 4 is driven to slide leftward or rightward along the inner wall of the T-shaped groove 13 by the pull rod 7 to adjust the position of the cutting knife 4. When adjusted to the appropriate position, the block 15 is loosened, and the block 15 is clamped with the slot 8 under the elastic force of the limit spring 14, enabling the square plate 3 to limit the pull rod 7 and keeping the cutting knife 4 in a fixed state. By changing the position of the cutting knife 4, the cutting size of the valve pocket can be changed.
[0035] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
