Technical Field

[0001] The present invention relates to the technical field of spring processing, in particular to a torque adjustment device for spring processing. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. There are many types of springs. According to their shapes, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. After the spring is produced, it is necessary to test the relevant properties of the spring, such as compressive resistance and tensile strength, to ensure product quality and product safety.

[0003] In spring manufacturing, precise torque adjustment is an important factor in ensuring spring performance and product quality. Under different application requirements, springs require specific torque characteristics. Traditional adjustment methods may involve manual operation or simple mechanical devices. These methods may lack precision and efficiency. How to accurately measure and adjust the torque of the spring is a huge problem currently.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-6As shown, one embodiment of the present invention is: a torque adjustment device for spring processing, comprising

[0031] The base 1 is provided with a protective mechanism 11 and a vertical plate 9 on the surface;

[0032] A protection mechanism 11 is used to protect the spring for torque measurement;

[0033] A vertical plate 9, with a cutting mechanism 10 mounted on the surface;

[0034] The cutting mechanism 10 is used to cut the spring by the number of coils after the torsion is measured and needs to be adjusted.

[0035] A slide groove 2 is provided on the surface of the base 1, and a screw 3 is provided in the slide groove 2. One end of the screw 3 passes through the base 1 and is connected to the motor 1 4. A sliding plate 5 is slidably connected to the screw 3, and a motor 2 6 is provided on the top of the sliding plate 5. The output end of the motor 2 6 is connected to a torque meter 7. The vertical plate 9 is fixed on the surface of the base 1, and a hook 10 is provided on the surface of the vertical plate 9. A cutting mechanism 11 is provided at the upper end of the hook 10.

[0036] When this embodiment is working, the screw rod 3 is rotated by the motor 1 4, so that the sliding plate 5 is moved, which can adapt to the torque detection of springs of different lengths. When the torque of the spring needs to be adjusted, one end of the spring is hung on the hook 10, and the other end of the spring is hung on the torque meter 7. By starting the motor 2 6 to drive the torque meter 7 to rotate, the spring is driven to twist. The torque meter 7 tests the torsional force of the spring. By performing torque tests on different positions of a spring, a suitable torque position is obtained. At this time, the motor 2 6 is reversed to release the spring from the twisted state, and then the cutting mechanism 11 is started to cut the spring coil at the position of the torque meter 7 to achieve the torque adjustment of the spring.

[0037] On the basis of the above embodiment, in another embodiment of the present invention, the protective mechanism 11 includes an inverted L-block 801, a groove is provided at the bottom of the horizontal block of the inverted L-block 801, a bidirectional screw rod 802 is provided in the groove, and movable plates 803 are provided at both ends of the bidirectional screw rod 802, and grooves are provided on the inner sides of the two movable plates 803. A cylinder 1 805 is provided at the bottom of the movable plate 803, and the output end of the cylinder 1 805 passes through the movable plate 803 and is connected to the connecting plate 806. A protective tube 807 is provided at the end of the connecting plate 806, and one end of the bidirectional screw rod 802 passes through the inverted L-block 801 and is connected to the output end of the motor three 804.

[0038] When this embodiment is working, when one end of the spring is hung on the hook 10 and the other end of the spring is hung on the torque meter 7, the motor three 804 is started, and the motor three 804 drives the bidirectional screw rod 802 to rotate, so that the movable plates 803 at both ends of the bidirectional screw rod 802 move toward each other. At the same time, according to the diameter of the spring, the cylinder one 805 at the bottom of the movable plate 803 is started, and the cylinder one 805 drives the protective tube 807 provided on the connecting plate 806 to move to the appropriate position, thereby preventing the spring from falling off during the torque test and causing harm to the staff.

[0039] On the basis of the above embodiment, in another embodiment of the present invention, the cutting mechanism 11 includes a shell 111, a groove is provided at the bottom of the shell 111, a threaded rod 112 is provided in the groove, a moving block 116 is slidably connected to the threaded rod 112, a cylinder 2 117 is embedded in the bottom of the moving block 116, the output end of the cylinder 2 117 is connected to a hydraulic shear 118, a motor 4 113 is provided on the surface of the shell 111, the output end of the motor 4 113 passes through the shell 111 and is connected to a driving gear 114, the driving gear 114 is meshed with a driven gear 115, and the driven gear 115 is fixedly connected to the threaded rod 112.

[0040] When this embodiment is working, when the torque test of different positions of the spring is completed, the appropriate torque adjustment position is obtained, and the torque adjustment of the spring can be achieved by reducing the number of coils of the spring. At this time, by starting motor four 113, motor four 113 drives the threaded rod 112 to rotate, so that the moving block 116 moves on the threaded rod 112. When the moving block 116 moves to the appropriate torque adjustment position, cylinder two 117 is started, and cylinder two 117 drives the hydraulic shear 118 to move downward. When it moves to the coil at the appropriate torque adjustment position, the hydraulic shear 118 cuts the coil. By reducing the coil of the spring, the torque adjustment of the spring is achieved, which solves the problem that the existing equipment is difficult to adjust the spring torsion.

[0041] When adjusting the torsion of the spring, the present invention first hangs one end of the spring to be tested on the hook 10, and drives the screw 3 to rotate by the motor 1 4, so that the sliding plate 5 moves to adapt to springs of different sizes, and then hangs the other end of the spring to be tested on the torque meter 7, starts the motor 3 804, and the motor 3 804 drives the bidirectional screw rod 802 to rotate, so that the movable plates 803 at both ends of the bidirectional screw rod 802 move toward each other, and at the same time, according to the diameter of the spring, starts the cylinder 1 805 at the bottom of the movable plate 803, and the cylinder 1 805 drives the protective tube 807 provided on the connecting plate 806 to move to the appropriate position. The two protective tubes 807 wrap the spring, and at this time, the torque meter 7 is driven to rotate by starting the motor 2 6, which drives the spring to twist, and the torque meter 7 tests the torsion force of the spring. At this time, the torsion of the spring can be measured, and then the torque meter is hung on the coil at the front end of the spring test position to perform a secondary torsion force test, and this step is repeated until the appropriate torque adjustment position is found.

[0042] When a suitable torque adjustment position is found, motor four 113 is started, and motor four 113 drives the threaded rod 112 to rotate, so that the moving block 116 moves on the threaded rod 112. When the moving block 116 moves to a suitable torque adjustment position, cylinder two 117 is started, and cylinder two 117 drives the hydraulic shear 118 to move downward. When it moves to the coil at a suitable torque adjustment position, the hydraulic shear 118 cuts the coil, and the torque adjustment of the spring is achieved by reducing the coil of the spring.
