Description

Technical Field

[0001] This utility model relates to the field of spring length detection technology, specifically a spring length detection device. Background Technology

[0002] As a key basic component in fields such as machinery, electronics, automobiles, and aerospace, the length and dimensions of springs directly affect the performance of equipment (such as elastic force and deformation threshold). With the increasing level of industrial automation, the demand for high-precision springs (such as miniature springs for precision instruments and automotive suspension springs) has surged. Traditional manual measurement (such as vernier calipers and micrometers) suffers from problems such as low efficiency, large human error, and inability to adapt to batch testing, which has driven the development of specialized testing equipment.

[0003] Currently, the common method for measuring spring length in existing technologies is to manually use general measuring tools such as tape measures, steel rulers, or vernier calipers. This method requires rotating the spring, measuring multiple points, and then averaging the results. The process is extremely cumbersome and time-consuming, making it difficult to meet the high-efficiency testing requirements of modern large-scale production. Therefore, this paper proposes a spring length testing device. Utility Model Content

[0028] In an embodiment of this utility model, in order to detect the spring length, the detection component 6 specifically includes a housing 61, a second slider 64, and an electric actuator 68. The housing 61 is fixedly connected to the top of the workbench 2. A first fixing block 62 is fixedly connected to the inner wall of the housing 61. A groove 63 is provided on the outer wall of the first fixing block 62. The second slider 64 is slidably connected to the inner wall of the groove 63. A vertical plate 65 is fixedly connected to the bottom of the second slider 64. A pressure sensor 66 is provided on the outer wall of the vertical plate 65. A vision sensor 67 is provided on the bottom of the second slider 64. The first electric actuator 68 is installed on the outer wall of the housing 61, and the output end of the first electric actuator 68 is fixedly connected to the second slider 64.

[0029] Furthermore, the moving component 7 includes a fixed plate 71, which is fixedly connected to the top of the worktable 2. A slide rail 72 is fixedly connected to the left side of the fixed plate 71. A slide table 73 is slidably connected to the outer wall of the slide rail 72. An electric actuator 74 is installed on the outer wall of the fixed plate 71. The output end of the electric actuator 74 is fixedly connected to the slide table 73. A fixing block 75 is fixedly connected to the left side of the slide table 73. A guide rail 76 is slidably connected to the inner wall of the fixing block 75. A horizontal plate 77 is fixedly connected to the left side of the guide rail 76. A fixing block 78 is fixedly connected to the outer wall of the horizontal plate 77. An electric actuator 79 is installed on the left side of the slide table 73. The output end of the electric actuator 79 is fixedly connected to the fixing block 78.

[0030] Furthermore, the steering assembly 8 includes a connecting plate 81, which is fixedly connected to the left side of the cross plate 77. A rotating rod 82 is rotatably connected to the inner wall of the connecting plate 81. A clamping claw 83 is installed at the bottom of the rotating rod 82. The clamping claw 83 is pneumatically driven and its opening and closing action is achieved through a pneumatic claw cylinder. A connecting rod 84 is fixedly connected to the outer wall of the rotating rod 82. A connecting block 85 is fixedly connected to the left side of the fixed plate 71. A connecting rod 86 is hinged to the top of the connecting block 85. The connecting rod 86 is hinged to the connecting rod 84.

[0031] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that each electrical appliance can work normally. For example, electric slide rail 3, electric push rod 1 68, electric push rod 2 74, and electric push rod 3 79 are all connected to the mains power. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0032] In operation, during the spring loading stage, the spring to be tested is pre-placed in the placement frame 9 at the top of the workbench 2. When the testing frame 5 moves below the placement frame 9 via the electric slide rail 3, the spring is inserted into the testing frame 5 along the notch in the placement frame 9. The spring moves into the housing 61 along with the electric slide rail 3, slider 4, and testing frame 5. The electric push rod 68 retracts, causing slider 64 to slide to the right along the groove 63 of the fixed block 62, bringing the pressure sensor 66 on the vertical plate 65 into contact with the spring and applying pressure to ensure the spring is in a standard testing state. Then, the vision sensor 67 at the bottom of slider 64 performs a non-contact image capture of the spring, accurately measuring its length using image recognition and processing technology. After testing, the electric push rod 68 extends and resets, and the spring continues to move along with the electric slide rail 3, slider 4, and testing frame 5. Electric actuator 2 74 is activated, and its output end pushes the slide table 73 to slide up and down on the slide rail 1 72. Then, electric actuator 3 79 is activated, pushing the fixed block 3 78 to drive the horizontal plate 77 and the guide rail 76 to slide on the inner wall of the fixed block 2 75. At this time, through the hinge between connecting rod 1 84 and connecting rod 2 86, the rotating rod 82 rotates in the connecting plate 81, thereby driving the bottom clamping claw 83 to rotate. The clamping claw 83 is pneumatically driven, and the air claw cylinder controls its opening and closing to stabilize the clamping spring. After clamping, electric actuator 2 74 drives the slide table 73 to move upward, and electric actuator 3 79 retracts to drive the horizontal plate 77 to move to the right. Due to the hinge between connecting rod 1 84 and connecting rod 2 86, the movement of the horizontal plate 77 causes the rotating rod 82 to rotate, realizing the 90-degree rotation of the spring. The spring that has been tested is transported to the inclined plate 10 on the right side of the workbench 2. The spring will automatically slide down the inclined plate 10 into the collection box, completing the entire testing process.
