Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a spring processing limiting device. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is generally made of spring steel and has the function of storing energy, but it cannot slowly release the energy. A spring that conforms to "Hooke's Law" is a real spring, that is, the elongation of the spring is proportional to the magnitude of the force it receives. In Chinese patent announcement number CN 219425545 U, a limit device for automobile spring processing is disclosed, including a base, a mounting groove is provided inside the base, a support plate is provided inside the mounting groove, a connecting through hole is provided inside the support plate, a rotating shaft rod adapted to the inner diameter of the connecting through hole is rotatably connected inside the connecting through hole, a transmission thread is provided on the outer surface of the rotating shaft rod, and the rotating shaft rod is connected to the connecting plate through the transmission thread, a rectangular slide groove adapted to the cross section of the connecting plate is provided on the upper surface of the base, and the connecting plate is slidably connected inside the rectangular slide groove, a mounting groove is provided inside the connecting plate, and a first motor is provided inside the mounting groove.

[0003] In the above technical scheme, the traction rope is wound around the rotating shaft by twisting the rotating knob, driving the fixed clamping plate to slide along the fixed sliding rod, squeezing the second spring, and conveniently clamping automobile springs of different sizes, and then adjusting the distance between the four limiting arc plates through the cooperation of the second motor, adjusting screw, moving ring, triangular extrusion block and the first spring, and then rotating the third motor and the first motor to drive the arc limiting plate to rotate and plug into the interior of the automobile spring. Although springs of different inner diameters can be limited, the structure is complicated and the operation is troublesome. The first step of limiting is to limit the second spring by the elastic potential energy of the second spring, and the stability is relatively low, so that when further limiting is performed in the subsequent period, the staff may need to manually support the spring, which will affect the speed of the spring limiting and may affect the processing efficiency during the continuous processing of the spring.

Two rectangular plates 304 are threadedly installed on the outer wall of the bidirectional screw 302, and the rectangular plates 304 are slidably installed on the inner wall of the rectangular slot 301. A motor 307 is installed on the right side of the bidirectional screw 302, and the motor 307 is installed on the surface of the fixed plate 1. In this embodiment, by starting the motor 307, the bidirectional screw 302 is driven to rotate, and the two rectangular plates 304 are driven to slide on the inner walls of the two rectangular slots 301 respectively, in a motion trajectory away from each other, thereby adjusting the distance between the two rectangular plates 304.

[0026] like Figure 1 As shown, a connecting groove 303 is provided on the top of the fixed plate 1, and fixing rods 305 are installed on the surfaces of the two rectangular plates 304, and the two fixing rods 305 are slidably installed on the inner wall of the connecting groove 303, and a spreading rod 306 is installed on the top of the two fixing rods 305. In this embodiment, a spring is sleeved on the two spreading rods 306. When the two rectangular plates 304 move away from each other, the two fixing rods 305 are driven to slide away from each other in the connecting groove 303, and the two spreading rods 306 move accordingly, fit tightly with the inside of the spring, limit it, and avoid deformation during processing.

[0027] like Figure 1 As shown, friction pads are installed on the surfaces of the two spreading rods 306, and the friction pads are made of rubber. In this embodiment, the internal friction resistance with the spring is enhanced by the provision of the rubber friction pads, thereby improving the stability of the limit.

[0028] like Figure 1-3 As shown, the clamping mechanism 4 includes two limit rods 402, the top of the fixed plate 1 penetrates two limit slots 401, and the limit rods 402 are slidably installed on the inner wall of the limit slots 401, the bottom of the fixed plate 1 is rotatably installed with a cylinder 404, the bottom of the cylinder 404 is installed with a gear 405, the bottom of the fixed plate 1 is installed with a U-shaped plate 407, the surface of the U-shaped plate 407 is installed with a motor 2 406, and the output end of the motor 2 406 is installed at the bottom of the gear 405, the two limit rods 402 A connecting rod 403 is installed at the bottom, and a gear rod 408 is installed on the surface of the two connecting rods 403, and the two gear rods 408 are meshed with the gear 405. In this embodiment, by starting the second motor 406, the gear 405 and the cylinder 404 are driven to rotate synchronously, and the gear 405 rotates, driving the two gear rods 408 to move laterally, and the two connecting rods 403 and the two limit rods 402 move accordingly, moving closer to or away from each other, thereby adjusting the distance between the two limit rods 402.

The rod 306 moves accordingly, fits tightly with the inside of the spring, limits it, and prevents it from deforming during the processing. The rubber friction pad is set to enhance the internal friction resistance with the spring and improve the stability of the limit. By starting the second motor 406, the gear 405 and the cylinder 404 are driven to rotate synchronously. The gear 405 rotates, driving the two gear rods 408 to move laterally, and the two connecting rods 403 and the two limiting rods 402 move accordingly, moving towards or away from each other, thereby adjusting the distance between the two limiting rods 402. When the two limiting rods 402 move towards each other, they drive the four clamping blocks 409 to move towards each other in pairs of two, clamping and fixing the outside of the spring. The setting of the protective pad, which is made of rubber material, can enhance the friction resistance in contact with the outside of the spring and enhance the stability of the fixation.
