Description

Technical Field

[0001] This utility model relates to a spring testing machine and belongs to the field of spring testing technology. Background Technology

[0002] As a fundamental component widely used in the mechanical field, the mechanical properties of springs (such as elastic strength, compressive strength, and stress stability) directly determine the operating accuracy and service life of downstream equipment. Therefore, after spring production, their performance must be fully inspected using specialized testing equipment to screen out qualified products. However, in the industry, the mainstream method for full inspection testing of springs still relies on traditional spring testing machines for individual testing. The entire process of loading, testing, and sorting individual springs requires manual intervention, resulting in low testing efficiency, inability to achieve continuous operation, and difficulty in meeting the testing needs of large-scale production scenarios. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a spring testing machine, which solves the problem that in the existing technology, the mainstream method for full inspection testing of springs still relies on traditional spring testing machines for individual testing operations. The entire process of feeding, testing and sorting a single spring requires manual intervention, which cannot achieve continuous operation, has low testing efficiency and is difficult to meet the testing needs of large-scale production scenarios.

[0005] By adopting the above technical solution, the door is first opened, and the springs to be tested are placed in the positioning sleeves and abut against the pads. The rotating table of the drive structure rotates, and the rotating table moves synchronously with the positioning sleeves and springs. When the spring is aligned with the stress bar, the stress bar is moved towards the spring by the pushing structure, and the stress bar releases the stress on the spring.

Then, based on the pressure data, the spring moves towards the discharge hole again with the rotation of the rotating table. When the positioning sleeve is aligned with the discharge hole, the spring moves towards the discharge hole within the positioning sleeve by its own gravity. Finally, the collection structure collects and processes springs of different strengths.

[0025] like Figure 3 and Figure 4 As shown, the pushing structure includes a mounting base 1021, a cylinder 1022, a mounting block 1023, and a guide rail 1024. The mounting base 1021 is fixedly installed inside the processing box 2. The cylinder 1022 is fixedly installed on the mounting base 1021. The mounting block 1023 is fixedly connected to the output end of the cylinder 1022. The cylinder 1022 is connected to an external air source and an air pipe, which provides power to the cylinder 1022.

The pressure rod 9 is fixedly installed on the protective cover 1042 and electrically connected to the sensor 1041.

[0028] like Figure 3 As shown, the collection structure includes a first collection box 11, a second collection box 12, a third collection box 13, a hopper 1054, and an adjustment unit. The first collection box 11, the second collection box 12, and the third collection box 13 are arranged between the support frame 1 and the processing box 2. The hopper 1054 is arranged on one side of the support frame 1, and one side of the hopper 1054 is connected to the discharge hole 10. The other end of the hopper 1054 can be aligned with the first collection box 11, the second collection box 12, or the third collection box 13. The first collection box 11, the second collection box 12, and the third collection box 13 are used to collect springs 7 of qualified strength, springs 7 of relatively strong strength, and springs 7 of relatively weak strength, respectively. The hopper 1054 is in the shape of an inverted triangle. The adjustment unit is arranged on the support frame 1 and is used to adjust the position of the hopper 1054. The first motor 1011, the second motor 1034, the cylinder 1022, and the rodless cylinder 1052 are all electrically connected to the signal control module. The operation of the first motor 1011, the second motor 1034, the cylinder 1022, and the rodless cylinder 1052 can be automatically controlled by the industrial computer 4.

[0029] like Figure 6 and Figure 7 As shown, the adjustment unit includes a mounting plate 1051, a rodless cylinder 1052, and an adjustment block 1053. The mounting plate 1051 is fixedly mounted on the support frame 1, and the rodless cylinder 1052 is fixedly mounted on the mounting plate 1051. The rodless cylinder 1052 is connected to an external air source and air pipe, and is powered by the external air source and air pipe. The adjustment block 1053 is poweredly connected to the rodless cylinder 1052, and the side of the adjustment block 1053 away from the rodless cylinder 1052 is fixedly connected to the hopper 1054. The hopper 1054 moves synchronously with the adjustment block 1053. The first collection box 11, the second collection box 12, and the third collection box 13 are all rotatably equipped with moving wheels 1061 on the side away from the processing box 2. The first collection box 11, the second collection box 12, and the third collection box 13 are hinged with handles 1062 on the side away from the processing box 2.

[0030] Once the spring 7 has finished collecting, the handle 1062 can be pushed to move the first collection box 11, the second collection box 12, and the third collection box 13 under the action of the moving wheel 1061.

[0031] First, open the door 3 and place the springs 7 to be tested into the positioning sleeves 15 and abut against the pads 5. Then, start the first motor 1011 to drive the drive disc 1013 to rotate. During the rotation of the drive disc 1013, the rotating table 6 is driven to rotate. When the rotating table 6 moves, it simultaneously drives the positioning sleeves 15 and the springs 7 to move. When the springs 7 are aligned with the stress rods 8, the cylinder 1022 is started to push the mounting block 1023 to move. During the movement, the mounting block 1023 pushes the stress rods 8 towards the springs 7, releasing the stress on the springs 7. By releasing the stress on the springs 7, the residual internal stress inside the springs 7 can be effectively eliminated, so that the subsequent pressure test can accurately reflect the strength performance of the springs 7 themselves. This provides real and reliable data for product quality screening and avoids test errors caused by internal stress interference. After being released, the spring 7 rotates again with the rotary table 6, causing the rotary table 6 to move the spring 7 towards the pressure rod 9 under the action of the positioning sleeve 15. When the spring 7 is aligned with the pressure rod 9, the second motor 1034 is started to drive the threaded rod 1035 to rotate. Under the action of the threaded structure, the threaded rod 1035 drives the sliding block 1033 to slide in the sliding groove 1032. During the sliding process, the sliding block 1033 drives the protective cover 1042, sensor 1041, and pressure rod 9 to move towards the spring 7, so that the pressure rod 9 performs a pressure test on the spring 7. The pressure rod 9 transmits the measured pressure signal data to the industrial computer 4 through the sensor 1041 and the signal control module. Then, based on the pressure data, if the current data indicates that the pressure is weak, then... The rodless cylinder 1052 drives the adjusting block 1053 to move, causing the adjusting block 1053 to move the hopper 1054 towards the third collection box 13. Once the hopper 1054 is aligned with the third collection box 13, the rotating table 6 rotates again, causing the spring 7 to move towards the discharge hole 10. When the positioning sleeve 15 is aligned with the discharge hole 10, the spring 7 moves towards the discharge hole 10 within the positioning sleeve 15 due to its own weight, causing the spring 7 to fall through the discharge hole 10 into the hopper 1054. The hopper 1054 then transports the spring 7 to the third collection box 13 for centralized collection. By controlling the position of the hopper 1054, springs 7 of different strengths can be sorted, significantly reducing manual operation steps and improving testing accuracy. This device can simultaneously carry and transport multiple springs 7 without requiring full manual intervention, enabling continuous testing operations, significantly reducing the testing cycle of a single spring 7, effectively meeting the batch testing needs of large-scale production scenarios, and greatly improving production efficiency.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
