The bottom of the lower triangular plate is slidably connected to the top of the lower fixing clamp.

[0011] The clamping anti-deviation mechanism includes two support plates, each with multiple sliding columns slidably connected inside.

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please see Figures 1 to 3 This utility model provides a technical solution: a tensile testing device for automotive spring production and processing, comprising two slotted vertical plates 2, which serve as the two side support frames of the device, supporting the weight of the upper structure and providing vertical guidance. A top plate 13 is fixedly connected to the outer adjacent side of the two slotted vertical plates 2. The top plate 13 is a horizontally arranged rectangular steel plate, used to stably connect the tops of the two slotted vertical plates 2 and provide an installation foundation for the fixing column 3. A fixing column 3 is fixedly connected to the bottom of the top plate 13. The fixing column 3 is a cylindrical metal component used to suspend and fix the upper fixing mechanism 4 below the top plate 13 and ensure its stable position. The upper fixing mechanism 4 is fixedly connected to the bottom of the fixing column 3. The upper fixing mechanism 4 is a fixing device for the upper end of the spring, used to realize the quick clamping and positioning of the spring 472 to be tested. The bottom of the upper fixing mechanism 4 is slidably connected to the lower fixing clamp 12. The lower fixing clamp 12 is a U-shaped groove structure, used to fix the lower end of the spring 472 to be tested and move synchronously with the lifting plate 5. The bottom of the lower fixing clamp 12 is fixedly connected to the lifting plate 5. The lifting plate 5 is a horizontally placed rigid plate, used to support the lower fixing clamp 12 and the clamping anti-deviation mechanism 6 and transmit the lifting driving force. The top of the lifting plate 5 is fixedly connected to the clamping anti-deviation mechanism 6. The clamping anti-deviation mechanism 6 is composed of symmetrically arranged elastic clamping components, used to limit the lateral displacement of the spring 472 to be tested during the testing process.

[0026] The upper fixing mechanism 4 includes a U-shaped perforated plate a41, which is a U-shaped steel plate with holes on both sides to provide installation space and sliding track for the cylindrical pin 43. The top of the U-shaped perforated plate a41 is fixedly connected to the bottom of the fixing column 3. A U-shaped perforated plate b42 is fixedly connected to the outer left side of the U-shaped perforated plate a41. The U-shaped perforated plate b42 is a U-shaped structure with a baffle on the left side to install the spring a45 and limit its lateral displacement. The cylindrical pin 43 is slidably connected inside the U-shaped perforated plate b42. The cylindrical pin 43 is used to insert and fix the upper triangular plate 471 and achieve quick positioning. A fixing ring 44 is fixedly connected to the outer side of the cylindrical pin 43. The fixing ring 44 is an annular component sleeved on the cylindrical pin 43 to block the right end of the spring a45 and transmit elastic force. The spring a45 is provided on the left side of the fixing ring 44. 5. Spring a45 is a compression spring, used to push the fixed ring 44 with elastic force to keep the cylindrical pin 43 in the locked position. The outer left side of the cylindrical pin 43 is fixedly connected to the drive assembly 46, which is a manually operated component, used to drive the cylindrical pin 43 to slide left and right to unlock and lock. The outer side of the cylindrical pin 43 is slidably connected to the tensile test assembly 47, which is a combination of the spring 472 to be tested and the connecting component, used to generate deformation under tensile force and complete the testing process. The outer side of the cylindrical pin 43 is slidably connected to the inside of the U-shaped opening plate a41 to ensure that the cylindrical pin 43 can slide smoothly in the horizontal direction. The outer left side of spring a45 is fixedly connected to the inside of the U-shaped opening plate b42 to fix the left end of spring a45 and generate a rightward thrust through compression deformation.

[0027] The drive assembly 46 includes a drive column 461, which is a metal rod connecting the cylindrical pin 43 and the lifting ring 462. The drive column 461 converts the lifting action into a lateral driving force. The outer right side of the drive column 461 is fixedly connected to the outer left side of the cylindrical pin 43. The lifting ring 462 is slidably connected inside the drive column 461. The lifting ring 462 is a ring-shaped hand grip, providing a point of force application for manual operation and rotating around the drive column 461. The tensile testing assembly 47 includes an upper triangular plate 471, which is a triangular metal plate with mounting holes at its three corners. These holes connect the cylindrical pin 43 and the spring 472 to be tested, ensuring balanced force distribution. The inner sliding connection of 71 is to the outside of the cylindrical pin 43. The bottom of the upper triangular plate 471 is fixedly connected to the spring 472 to be tested. The spring 472 to be tested is an automotive spring that needs to be tested for tension. It has hooks or connecting rings at both ends. The bottom of the spring 472 to be tested is fixedly connected to the lower triangular plate 473. The lower triangular plate 473 is a triangular metal plate with the same structure as the upper triangular plate 471. It is used to connect the lower end of the spring 472 to be tested and transmit the tension to the lower fixed clamp 12. The bottom of the lower triangular plate 473 is slidably connected to the top of the lower fixed clamp 12 to ensure that the lower triangular plate 473 can be stably installed on the lower fixed clamp 12 without relative sliding.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the clamping anti-deviation mechanism 6 includes two support plates 61, which are steel plates vertically fixed to the lifting plate 5. These plates are used to mount sliding columns 62 and provide stable support. Multiple sliding columns 62, which are smooth metal columns, are slidably connected inside each support plate 61. These columns guide the lateral movement of the semi-circular clamp 64 and limit its direction of movement. Multiple springs b63, which are tension springs, are provided on adjacent sides of the outer surfaces of both support plates 61. These springs are used to maintain the semi-circular clamp 64 through elastic tension. The clamp 64 always holds the spring in a clamping state. The other end of the spring b63 is fixedly connected to the semi-circular clamp 64. The semi-circular clamp 64 is a metal block with an arc-shaped groove on the inside. Its arc-shaped surface matches the outer wall of the spring 472 to be tested, so as to fit the spring surface and limit its lateral displacement. The outside of the semi-circular clamp 64 is fixedly connected to the outside of the sliding column 62. The inside of multiple semi-circular clamps 64 is slidably connected to the outside of the spring 472 to be tested, so that the spring 472 to be tested can maintain the stability of the axial direction during the stretching process.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, a testing platform 1 is fixedly connected to the bottom of the two slotted vertical plates 2. The testing platform 1 is a rectangular metal platform used to support the weight of the entire device and provide a mounting reference surface for each component. A pressure testing chassis 11 is fixedly connected to the top of the testing platform 1. A motor a7 is fixedly connected to the left side of the inside of the testing platform 1, which can provide stable rotational power and precisely control the speed. A lead screw a8 is fixedly connected to the drive end of the motor a7. The lead screw a8 is a metal rod with external threads, used to convert the rotational motion of the motor a7 into the linear motion of the lifting plate 5. A testing platform 1 is fixedly connected to the right side of the inside. There is a motor b9, which works in conjunction with motor a7 to ensure the smooth movement of the lifting plate 5. The drive end of motor b9 is fixedly connected to lead screw b10, which is a transmission component with the same structure as lead screw a8. It is used to drive the lifting plate 5 from the right side to achieve the lifting action. The external thread of lead screw a8 is connected to the front inside of the lifting plate 5, so that the lifting plate 5 can move in the vertical direction under the rotation drive of lead screw a8. The external thread of lead screw b10 is connected to the rear inside of the lifting plate 5, and the synchronous rotation with lead screw a8 ensures that the lifting plate 5 always remains in a horizontal state during the movement.

[0030] Working principle: The operator pulls the transmission column 461 through the lifting ring 462 in the drive assembly 46, which in turn moves the cylindrical pin 43 to the left. At this time, the fixing ring 44 compresses the spring a45, causing the cylindrical pin 43 to move a certain distance from the corresponding positions of the U-shaped perforated plate a41 and the U-shaped perforated plate b42. Then, the upper end of the spring 472 to be tested is connected to the upper triangular plate 471 in the tensile testing assembly 47. Then, the lifting ring 462 is released. Under the reset action of the spring a45, the cylindrical pin 43 moves to the right and passes through the upper triangular plate 471, thus moving the upper triangular plate 471 to the left. 1. Fix the upper end of the spring 472 to be tested inside the U-shaped perforated plate a41 to complete the fixation. Then, connect the lower end of the spring 472 to be tested to the lower triangular plate 473 and place the lower triangular plate 473 on the top of the lower fixing clamp 12 to achieve the initial positioning of the lower end of the spring 472 to be tested. At the same time, under the action of the spring b63, the multiple semi-circular clamps 64 in the clamping anti-deviation mechanism 6 slide in the support plate 61 through the sliding column 62 to clamp the spring 472 to be tested inside from both sides to prevent the spring 472 to be tested from shifting during the testing process.

[0031] Upon entering the testing phase, the motors a7 on the left and b9 on the right inside the testing platform 1 are activated. Motor a7 drives the lead screw a8 to rotate, and motor b9 drives the lead screw b10 to rotate. Since the lead screw a8 is threaded to the front of the lifting plate 5 and the lead screw b10 is threaded to the rear of the lifting plate 5, the rotation of the lead screws a8 and b10 causes the lifting plate 5 to move downward. This, in turn, causes the lower triangular plate 473 and the lower end of the spring 472 to be tested to move downward through the lower fixed clamp 12, applying a tension force to the spring 472. Under the action of the tension force, the spring 472... The two slotted vertical plates 2 are stretched and provide stable support for the top plate 13. The top plate 13 provides fixed support for the upper fixed mechanism 4 through the fixed column 3, ensuring the stability of the testing process. After the test is completed, the motors a7 and b9 are turned off, so that the lead screws a8 and b10 stop rotating and the lifting plate 5 stops moving. The transmission column 461 is pulled again by the lifting ring 462, so that the cylindrical pin 43 moves to the left and disengages from the upper triangular plate 471. The upper triangular plate 471 is removed from the U-shaped opening plate a41, and then the tested spring 472 is removed, completing the entire testing process.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
