In the invention patent with publication number CN116519454A, a spring tensile strength testing device for spring processing is disclosed, which includes a testing platform, solving the problem that traditional spring tension testing devices are inconvenient to adjust and fix according to the size and diameter of the spring.

[0016] Beneficial effects This invention provides a multi-station inspection device for spring processing. Compared with the prior art, it has the following advantages: (1) By setting up a continuous inspection mechanism, multiple fixed cylinders are rotated by a turntable, and two sets of electromagnets are passed through the fixed cylinders, so as to realize continuous inspection of a large number of springs, thereby improving the inspection efficiency. At the same time, the fixed cylinders are used to store the springs, making the spring fixing simpler. The springs are compressed and inspected by the magnetic repulsion of the magnetic plate, thereby saving inspection space. The springs are unloaded through both ends of the fixed cylinders, and springs with different properties can be distinguished after inspection, so as to make the inspection process simple and effective.

[0017] (2) By setting up a feeding component, the linear motor drives the baffle to slide horizontally. The baffle can block the bottom of the solid cylinder to fix and support the spring. It can also release the baffle so that the spring can be fed by gravity, thereby improving the overall detection effect. The lifting rod drives the baffle to descend so that the solid column can abut against the spring exposed from the solid cylinder, thus facilitating the cutting of springs that are out of size.

[0018] (3) By setting up an auxiliary unit, the output end of the push-pull rod extends to allow the arc ring to slide and be sleeved on the outside of the spring. Then, by pushing the arc ring, the spring made of magnetic material can be pushed and demagnetized, which facilitates the unloading of the magnetic material spring. At the same time, the motor is adjusted to make the laser cutter adjust its position around the spring through repulsion and gear ring transmission, so as to make laser cutting at the appropriate part of the oversized spring, so that the spring after inspection is compliant, thereby improving the application range of the device and making the inspection work simpler and more effective.

[0019] (4) By setting up a transfer component, the stability of the magnetic plate after sliding out of the solid cylinder can be improved by using the connection between the clamp and the slider. At the same time, the magnetic plate can be transferred between two sets of electromagnets by using the transfer motor and the rotating arm. This makes it easier for the solid cylinder to unload the spring after testing, and also makes it easier to load the spring to be tested. During the transfer, the double clamping of the slider by the movement of the clamp can further improve the stability of the magnetic plate during the transfer. Attached Figure Description

The electromagnet 11 is electrically connected to the external control circuit. The distance between the electromagnet 11 and the top of the solid cylinder 5 is the same as the thickness of the magnetic plate 9. The electromagnet 11 controls the magnetic plate 9 to move in and out of the solid cylinder 5 through magnetic force. Two sets of electromagnets 11 are provided to facilitate the feeding of springs into the solid cylinder 5. The two sets of electromagnets 11 are arranged adjacent to each other. Two adjacent receiving measures are provided below the turntable 2 to collect qualified and unqualified springs separately. One of the receiving measures is located directly below a set of electromagnets 11. A folding plate 12 is fixedly connected to the outer surface of the electromagnet 11.

[0025] The bottom of the fixed cylinder 5 is provided with a feeding assembly 6, which includes a baffle 61. The baffle 61 slides horizontally to support and fix the spring by blocking the bottom of the fixed cylinder 5, and to facilitate the spring's sliding and feeding. As a preferred method, the electromagnet 11 is provided with a third set. Through magnetic repulsion, the magnetic plate 9 and the baffle 61 compress the spring, so that the length of the oversized part of the spring is smaller when compressed, thereby shortening the descent distance of the baffle 61. The top of the baffle 61 is movably connected to the bottom of the fixed block 4. Both sides of the outer surface of the baffle 61 are provided with slide rails 62. The outer surfaces of both slide rails 62 are fixedly connected to the bottom of the fixed block 4. The outer surfaces of both slide rails 62 are slidably connected to linear motors 63.

The lifting rod 65 is made of an electric push rod and is electrically connected to an external control circuit. By driving the baffle 61 to descend, the oversized part of the spring can slide out from inside the fixed cylinder 5 for cutting. The output end of the lifting rod 65 is fixedly connected to the bottom of the baffle 61. A fixed column 66 is fixedly connected to the outer surface of the frame 64. The fixed column 66 is fixedly connected to the frame 64 by a detachable fastener and has multiple outer diameter sizes to accommodate springs of different specifications. By abutting against the center of the spring, it can prevent the compressed spring from bending, thereby avoiding errors in cutting the oversized part of the spring. The top of the fixed column 66 is slidably connected to the body of the baffle 61.

[0027] An auxiliary unit 67 is provided on the outside of the fixed column 66. The auxiliary unit 67 includes an arc ring 671. The arc ring 671 is made of a circular ring and has an opening. The width of this opening is greater than the specification of the spring and smaller than the inner diameter of the arc ring 671. A push-pull rod 672 is fixedly connected to the outer surface of the arc ring 671. The push-pull rod 672 is made of an electric push rod and is electrically connected to an external control circuit. One end of the push-pull rod 672 is fixedly connected to the outer surface of the column 1. The arc ring 671 is axially slidably sleeved on the outside of the fixed column 66.

A limiting ring 674 is slidably connected inside the limiting groove 673. A laser cutter 675 is provided at the top of the limiting ring 674. The laser cutter 675 is electrically connected to an external control circuit. The laser is used to cut the spring so that the out-of-gauge spring is within the acceptable size. The laser cutter 675 rotates radially around the fixed column 66 to cut the spring.

[0029] The outer surface of the laser cutter 675 and the outer surface of the limiting ring 674 are fixedly connected by a toothed ring 676. Both the toothed ring 676 and the limiting ring 674 are provided with openings of the same size as the arc ring 671, and the width of the toothed ring 676 is smaller than the width of the limiting ring 674. The cross-section of the two combined is T-shaped to improve the stability of the connection with the arc ring 671. The outer surface of the toothed ring 676 is movably connected to the inside of the limiting groove 673. A gear 677 meshes with the outer surface of the toothed ring 676. An adjusting motor 678 is fixedly connected to the outer surface of the gear 677. The adjusting motor 678 is made of a servo motor and is electrically connected to an external control circuit. The outer surface of the adjusting motor 678 is fixedly connected to the output end of the push-pull rod 672.

[0030] The slider 10 is provided with a transfer assembly 7 on its exterior. The transfer assembly 7 includes a clamp 71. The interior of the clamp 71 wraps around the exterior of one side of the slider 10. Preferably, the clamp 71 is made of magnetic material and fixes the magnetic plate 9 by magnetic attraction to facilitate the transfer of the magnetic plate 9. The clamp 71 is located outside the fixed cylinder 5. The interior of the clamp 71 is movably connected to the outer surface of the slider 10. A rotating arm 72 is fixedly connected to the outer surface of the clamp 71. A transfer motor 73 is fixedly connected to the outer surface of the rotating arm 72.

[0031] The clamp 71 has grooves 74 on both sides inside, and clamping plates 75 are movably connected inside the grooves 74 on both sides. The cross-section of the clamping plates 75 is the same as the cross-section of the grooves 74, and the thickness of the clamping plates 75 is less than the depth of the grooves 74. The outer surfaces of the clamping plates 75 that are close to each other are movably connected to the outer surface of the slider 10. The outer surfaces of the clamping plates 75 that are far apart from each other are fixedly connected to the balance rods 76. The balance rods 76 can improve the balance of the movement of the clamping plates 75. One end of the balance rods 76 on both sides is slidably connected to the body of the clamp 71 and extends to the outside of the clamp 71.

[0032] An adjusting rod 77 is fixedly connected to the outer surface of the clamp 71. The adjusting rod 77 is made of an electric push rod and is electrically connected to an external control circuit. A stop 78 is fixedly connected to the output end of the adjusting rod 77.

The stop 78 is sleeved on the outside of the clamp 71. The two ends of the stop 78 are respectively slidably connected to the body of the balance bar 76 on both sides and extend to the outside of the balance bar 76.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: During testing, a fixed cylinder 5 and a fixed column 66 with inner and outer diameters matching the size of the spring to be tested are selected. They are then installed on a fixed block 4 and a fixed frame 64, respectively. A robotic arm is used to place the spring to be tested inside the fixed cylinder 5, and the spring is supported by a baffle 61 at the bottom. Then, the turntable 2 rotates, causing the fixed cylinder 5 to move the spring to a position directly below a set of electromagnets 11. The above steps are repeated, placing the spring to be tested inside an adjacent unloaded fixed cylinder 5. At the same time, the electromagnets 11 are de-energized and demagnetized, causing the magnetic plate 9 to fall into the fixed cylinder 5. The magnetic plate 9 is kept balanced by the cooperation of the slider 10 and the slide groove 8. The magnetic plate 9 then initially compresses the spring to be tested by gravity. The laser rangefinder 15 measures the height of the slider 10. Then, the electromagnets 11 are energized and magnetized, causing the magnetic plate 9 to press down on the spring to be tested through magnetic repulsion. The height of the slider 10 is measured again by the laser rangefinder 15 to verify the accuracy of the test results by comparing the test results from both sides. Then, the turntable 2 drives the spring to move directly below another set of electromagnets 11. Next, the electromagnets 11, through magnetic attraction, cause the magnetic plate 9 to slide upwards and out of the fixed cylinder 5. Simultaneously, one side of the slider 10 slides into the clamp 71. Then, the output end of the adjusting rod 77 retracts, causing the abutment 78 to move and approach the clamp 71. Through the oblique contact between its two ends and the two side balance rods 76, the two side balance rods 76 push the corresponding clamping plates 75 to move towards each other, thus doubly clamping the slider 10 through the two side clamping plates 75. To further improve the stability of the magnetic plate 9, the transfer motor 73 drives the clamp 71 and the magnetic plate 9 to move via the rotating arm 72, thereby transferring the magnetic plate 9 to directly below the adjacent set of electromagnets 11 and fixing the magnetic plate 9 by magnetic attraction. Then, the clamp 75 resets and detaches from the reinforcement of the slider 10. Next, the magnetic plate 9 falls and slides into the adjacent solid cylinder 5 to compress and test the spring to be tested inside. Then, the transfer motor 73 rotates in the opposite direction to reset the clamp 71. The above steps are repeated to transfer the magnetic plate 9 for continuous testing. After the spring test is completed, if the spring fails the test and its performance is below the requirement, the linear motor 63 drives the baffle 61 to slide along the slide rail 62, causing the baffle 61 to disengage from the bottom of the fixed cylinder 5, thus allowing the internal spring to fall into the corresponding receiving device. If the spring is made of magnetic material and cannot slide out of the fixed cylinder 5 due to magnetic attraction, the output end of the push-pull rod 672 extends, and the arc ring 671 abuts and pushes the spring's sliding portion, allowing it to fall. If the spring's performance is above the requirement, the output end of the lifting rod 65 retracts, causing the baffle 61 to descend, allowing the excess portion of the spring to slide out from the bottom of the fixed cylinder 5. The baffle 61 and the magnetic plate 9 keep the spring compressed, while the compressed portion of the spring exposed from the fixed cylinder 5 is abutted by the center of the fixed column 66 to prevent the exposed compressed portion of the spring from bending. The output end of the push-pull rod 672 extends, causing the arc ring 671 to slide and be sleeved on the outside of the spring. Then, the adjusting motor 678 drives the transmission through the meshing of the gear 677 and the gear ring 676, so that the cutting point of the laser cutter 675 is aligned with the node of the oversized part of the spring. Then, the laser cuts the part. After the cutting is completed, the linear motor 63 slides horizontally with the baffle 61, and at the same time, the lifting rod 65 drives the baffle 61 to rise and reset, so that the cut part of the spring is pushed down. Alternatively, when the baffle 61 slides horizontally and resets to block the bottom of the solid cylinder 5, the side of the solid block 4 pushes the cut part of the spring down, so that it falls into the corresponding receiving device below. After the baffle 61 blocks the bottom of the solid cylinder 5 again, the electromagnet 11 pulls the magnetic plate 9 out of the solid cylinder 5 and then transfers it for continuous detection. Then, the turntable 2 drives the cut spring to move above another receiving device. If the spring passes the test, the turntable 2 moves the qualified spring, or the qualified spring after cutting, to the top of another receiving device. Then, the rotating motor 14 drives the solid block 4 and the solid cylinder 5 to rotate inside the rotating groove 3 through the rotating rod 13, so that the top of the solid cylinder 5 rotates downward, thereby causing the qualified spring inside the solid cylinder 5 to slide down into the corresponding receiving device. Then, the rotating motor 14 drives the solid cylinder 5 to reverse and reset. Then, through the transfer of the turntable 2, the continuous spring testing operation is carried out.
