Description

Technical Field

[0001] This utility model relates to a spring flaw detector, belonging to the technical field of spring testing equipment. Background Art

[0002] A spring is a mechanical part that operates using elasticity, and is generally made of spring steel. After springs are manufactured, to ensure their quality and performance meet standards and to avoid potential safety hazards, they need to undergo flaw detection. Spring flaw detectors work by applying a magnetic field to the spring and using magnetic powder to detect surface and near-surface defects. The magnetic powder accumulates at the defects, forming clear marks.

[0003] In existing spring flaw detectors, the spring cannot rotate while being sprayed with magnetic suspension liquid from the nozzle. This prevents the magnetic suspension liquid from completely covering the magnet surface, affecting the detection quality. Therefore, this invention proposes a spring flaw detector to solve the above problems. Utility Model Content

It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0021] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0023] like Figures 1-4As shown, a spring flaw detector includes a machine base 1. A water tank 2 is located on the top of the machine base 1. A feeding mechanism 3 is located within the water tank 2. A set of AC power controllers 4 is located near the center on both sides of the feeding mechanism 3. A turntable 5 is rotatably connected to the opposite surfaces of each set of AC power controllers 4. A through hole 6 is located in the center of each turntable 5. A through hole 7 is located on each set of AC power controllers 4. The through hole 7 and the through hole 6 are coaxially aligned. A connecting shaft 8 passes through the through hole 6 and the through hole 7. The perforation 7 extends through the inner side of the AC controller 4 and a sealing coil disc 9 is installed at its end. A U-shaped frame 10 is fixedly installed on the end face of the turntable 5 away from the AC controller. A cylinder 11 is installed on the U-shaped frame 10. The output shaft of the cylinder 11 is fixedly connected to the connecting shaft 8. An annular groove 12 is provided on the turntable 5. A motor 13 is installed on the top of the AC controller 4. A pulley 14 is installed on the output shaft of the motor 13. A transmission belt 15 is fitted on the pulley 14 and the annular groove 12.

[0024] In the above technical solution, by setting up a motor 13, the rotation of the motor 13 can drive the U-shaped frame 10 and the cylinder 11 to rotate via the transmission belt 15 and the turntable 5. This can drive the connecting shaft 8 and the sealing coil disc 9 to rotate in the perforation 7. When the cylinder 11 starts and clamps the spring between a set of sealing coil discs 9, it can drive the spring to rotate. When the nozzle 23 sprays magnetic suspension liquid onto the spring, it can completely cover the surface of the spring, ensuring the detection accuracy of the spring.

[0025] In this utility model, the feeding mechanism 3 includes a drive shaft 16 rotatably connected to the left end of the water tank 2 and a driven shaft 17 rotatably connected to the right end of the water tank 2. A set of transmission chains 18 are sleeved on the drive shaft 16 and the driven shaft 17. Several sets of equally spaced support blocks 19 are installed on the set of transmission chains 18. V-grooves 20 are opened on the support blocks 19. A servo motor 21 is installed at the left end of the front end of the machine base 1. The servo motor 21 is connected to the drive shaft 16.

[0026] In the above technical solution, by setting up the feeding mechanism 3, the rotation of the servo motor 21 can drive the drive shaft 16 to rotate, causing a set of transmission chains 18 sleeved on the drive shaft 16 and the driven shaft 17 to rotate, which in turn can drive the support block 19 installed on the transmission chain 18 to move. When the spring is placed in the V-groove 20 opened on the support block 19, the spring can be transported to a set of sealing coil discs 9.

[0027] In this utility model, a spray pipe 22 is provided in the water tank 2 at the top of the machine base 1. The end of the spray pipe 22 faces between a set of sealing coil discs 9, and a nozzle 23 is threadedly installed at the end of the spray pipe 22.

[0028] In the above technical solution, by setting the nozzle 23, when the spring is transported by the support block 19 to a set of sealing coil discs 9, the nozzle 23 sprays magnetic suspension liquid to spray the spring.

[0029] In this utility model, a feed hopper 24 is provided on the right side of the machine base 1, and the left end of the feed hopper 24 extends into the water tank 2.

[0030] In the above technical solution, by setting up a feed hopper 24, when the spring spray is magnetized, the feeding mechanism 3 operates. When the support block 19 moves to the rightmost end of the water tank 2, the spring falls into the feed hopper, and the spring can finally slide from the feed hopper into the light shield box 26.

[0031] In this utility model, a frame 25 is placed on the right side of the machine base 1, and a light shield 26 is provided on the top of the frame 25. An ultraviolet lamp 27 is installed inside the top of the light shield 26. A material outlet 28 is opened at the left end of the light shield 26. The material outlet 28 is fitted over the right end of the material hopper 24. An observation port 29 is opened on the front surface of the light shield 26, and a set of operation ports 30 is provided below the observation port 29.

[0032] In the above technical solution, by setting an ultraviolet lamp 27, when the spring falls into the light-shielding box 26, it will show fluorescence under the illumination of the ultraviolet lamp 27. Then, the operator can reach into the light-shielding box 26 through the operation port 30 to pick up the spring and observe whether there is an accumulation of magnetic powder particles on the surface of the spring through the observation port 29, so as to identify surface defects and thus perform flaw detection on the surface of the spring.

[0033] In this utility model, a discharge port 31 is provided on the end face of the light-shielding box 26, and a discharge hopper 32 is fixedly connected inside the discharge port 31.

[0034] In the above technical solution, by opening a discharge port 31 on the light-shielding box 26 and setting a discharge hopper 32 inside the discharge port 31, the material can fall out of the discharge hopper 32 and be collected after the spring flaw detection is completed.

[0035] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
