Description
Technical Field
[0001] This utility model relates to the field of material performance testing, specifically to a springback testing device. Background Technology
[0002] In the field of materials performance testing, rebound performance is an important indicator for measuring material quality. Rebound testing primarily involves applying impact force to the material using a specific device and then measuring parameters such as the height the material rebounds after the impact to evaluate its rebound performance. Accurate rebound testing is of great significance for materials research and development, quality control, and application selection.
[0003] Currently, common rebound testing devices generally employ a fixed impact structure. The test piece is typically fixed in a fixed position, and the impact component falls from a fixed height to impact it. During the testing process, adjusting the position and height of the impact component is inconvenient, mostly requiring manual adjustment with inconsistent accuracy. Furthermore, the installation and fixing methods for the test piece are limited, making it difficult to achieve stable and reliable fixing for test pieces of different sizes and shapes. This can easily lead to displacement and shaking during testing, affecting the accuracy of the results. In addition, existing testing devices require removing the test piece from the device and repositioning it before fixing it to different locations, a cumbersome process that reduces efficiency. Moreover, the measurement of the rebound height of the impact component is generally done manually, which is not only inaccurate but also susceptible to human error, resulting in significant inaccuracies in the measurement results.
[0004] Therefore, the above problems urgently need to be solved. Utility Model Content
[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a rebound detection device. Through the coordinated design of the adjustable support and the impact component, combined with the automatic measurement of the distance sensor, it can realize the rapid and accurate alignment of the impact position and the detection part, the automatic monitoring of the impact rebound height, and the flexible adaptation of the impact direction and force, thereby improving the efficiency of multi-position detection and the measurement accuracy of rebound data.
[0006] Technical Solution: This utility model provides a rebound detection device for detecting the rebound height of a test piece after being impacted. It includes a frame with a base plate at the bottom and a top plate at the top, and a pair of guide posts between the base plate and the top plate; a support seat located on the base plate and movably connected to it in the Y direction, with the test piece mounted on the support seat; an impact assembly located above the support seat and passing through the pair of guide posts, used to bounce back after impacting the test piece in the Z direction; and a distance sensor located on the top plate, with its detection head facing the impact assembly, used to measure the rebound height of the test piece after impact. Equipped with a movable support base, it can be movably connected to the base plate in the Y direction, facilitating the adjustment of the test piece's position to adapt to different testing needs. The impact component can bounce back after impacting the test piece in the Z direction, simulating the impact situation in actual use, and performing a rebound test on the test piece. A distance sensor is installed on the top plate, with its detection head facing the impact component, which can accurately measure the rebound height of the impact component after impacting the test piece, providing data support for rebound testing.
[0007] Furthermore, in a rebound detection device of this application, the impact assembly includes a retraction mechanism and an impact mechanism. The retraction mechanism includes a set of pulleys, a traction line, and a winding mechanism. The impact mechanism includes a hanging plate that passes through a pair of guide columns. A lifting lug is provided on the side of the hanging plate away from the base plate, and an impact block is installed on the other side. The pulleys and the winding mechanism are mounted on a frame. The traction line extends from the winding mechanism, winds around the pulleys, passes through a hole in the center of the top plate, and connects to the lifting lug. The retraction mechanism, through the cooperation of the pulleys, traction line, and winding mechanism, can flexibly control the lifting and lowering of the impact mechanism. The cable reel can reel in and out the traction cable, and the pulleys can be used to change the direction of the traction cable to achieve precise adjustment of the height of the hanging plate. This allows the impact block to be adjusted to the appropriate starting height in different testing scenarios to meet the needs of different impact forces on the test piece. The hanging plate of the impact mechanism is inserted through the guide column to ensure its stability in the Z direction. The lifting lug on one side of the hanging plate is used to connect the traction cable, and the impact block on the other side can directly impact the test piece to complete the core action of rebound detection.
[0008] Furthermore, in this application, a springback detection device includes a reel with a rotating handle and a release button. Rotating the handle reels in the traction line, thereby pulling the suspended plate up along the guide post to a designated position. When detection begins, pressing the release button causes the impact block and the suspended plate to impact the detection component along the Z-direction under gravity. It features manual control; rotating the handle reels in the traction line to adjust the height of the suspended plate, allowing it to be raised to any designated position along the guide post. This flexibly adjusts the initial height of the impact block before impacting the detection component, meeting the detection requirements for different impact forces. The release button, when needed, quickly releases the constraint on the traction line, allowing the impact block and the suspended plate to fall freely along the Z-direction under gravity to impact the detection component. Operation is simple, and the timing of the detection start can be accurately controlled.
[0009] Furthermore, in a springback detection device of this application, the base plate is provided with a pair of slide rails extending along the Y direction, and the bottom of the support seat is provided with a slider that cooperates with the slide rails. The sliding cooperation between the slider and the slide rails enables the support seat to be movably connected in the Y direction. This provides the support seat with the function of moving in the Y direction. The slide rails extending along the Y direction on the base plate cooperate with the slider at the bottom of the support seat, allowing the support seat to slide smoothly along the slide rails in the Y direction, facilitating the adjustment of the position of the detection component in the Y direction.
[0010] Furthermore, in a springback detection device of this application, the support seat has an adjusting lug on the side away from the top plate, and the base plate also has a pair of adjusting seats along the Y direction. The adjusting lug is located between the two adjusting seats in the Y direction, and the three are connected by a screw. A motor is mounted on one of the adjusting seats, and the motor drives the screw to rotate, thereby adjusting the support seat to move adjustablely along the slide rail in the Y direction. This achieves electrically adjustable movement of the support seat in the Y direction. The motor drives the screw to rotate, and the screw, in cooperation with the adjusting lug and adjusting seats, can precisely control the movement of the support seat along the slide rail in the Y direction, eliminating the need for manual pushing of the support seat and allowing for more precise adjustment of the position of the detection piece.
[0011] Furthermore, in a rebound detection device of this application, the support base has a groove and a pair of rotary pressing cylinders on the side away from the base plate. The detection element is disposed in the groove, and the rotary pressing cylinders are used to press against the detection element. The groove on the support base provides space for the detection element, enabling preliminary positioning of the detection element and placing it in a suitable detection position. The pair of rotary pressing cylinders can press against the detection element through rotation and pressing, firmly fixing the detection element in the groove and preventing the detection element from moving or displacing during the impact of the impact component. The rotary pressing cylinders allow the device to adapt to detection elements of different shapes and sizes. By adjusting the pressing force and rotation angle of the cylinders, different types of detection elements can be effectively fixed to meet diverse detection needs.
[0012] Furthermore, in a springback detection device of this application, the output end of the rotary pressing cylinder is provided with a pressure block, and the end of the pressure block is provided with an adjusting screw, which is perpendicular to the support seat. The setting of the adjusting screw helps to achieve precise positioning of the test piece. After the test piece is placed in the groove, the position of the pressure block can be finely adjusted by adjusting the screw, so that the test piece is in a more accurate detection position on the support seat, ensuring the accuracy of the detection.
[0013] Furthermore, in a rebound detection device of this application, the hanging plate is arranged along the X-direction, and a second slide rail is installed on the side away from the top plate. Second adjusting seats are respectively provided at both ends of the second slide rail. A second slider is slidably connected to the second slide rail, and an adjusting block is installed on the second slider. The impact block is detachably installed on the adjusting block, and the impact block faces the detection piece. The two second adjusting seats and the adjusting block are threadedly connected by a second screw. One end of the second screw is provided with an adjusting head. By rotating the adjusting head, the position of the adjusting block in the X-direction can be changed. By rotating the adjusting head, the second screw is driven to rotate. Since the two second adjusting seats and the adjusting block are threadedly connected by the second screw, the adjusting block can slide along the second slide rail in the X-direction, changing the position of the impact block in the X-direction. This allows for precise adjustment of the relative position of the impact block and the detection piece to adapt to different detection requirements. The impact block is detachably installed on the adjusting block, facilitating the replacement of impact blocks of different specifications and materials according to different detection objects or standards, enabling the device to perform diverse rebound detection.
[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0015] 1. The rebound detection device of this utility model achieves precise movement and positioning of the detection part in the Y direction through the sliding cooperation design of the bearing seat, slide rail and slider, combined with the screw adjustment mechanism driven by the motor; at the same time, through the coordinated control of the winding device, pulley and traction line in the impact assembly, the impact height of the impact block in the Z direction is precisely adjusted, and the rebound height is automatically measured by the distance sensor at the top, which significantly improves the efficiency of multi-position detection and the measurement accuracy of rebound data.
[0016] 2. The rebound detection device of this utility model achieves stable clamping of detection parts of different shapes by cooperating with the rotating pressing cylinder and the groove; the adjustment design of the second slide rail and the second screw in the X direction of the impact mechanism, as well as the detachable installation of the impact block, make the impact position and impact force flexibly adaptable according to the detection requirements, which solves the problem of fixed single and poor adaptability of traditional devices, and further improves the detection stability and application range.

[0036] Impact component 3:
[0037] The impact assembly includes a take-up and release mechanism 31 and an impact mechanism 32. The take-up and release mechanism consists of a set of pulleys 311, a traction line 312 and a reel 313, while the impact mechanism includes a hanging plate 321 and an impact block 322 mounted thereon.

[0040] Distance sensor 4:
[0041] The distance sensor is located on the top plate 12, facing the impact component, and can automatically measure the height of the rebound after the impact of the impact block, thereby accurately obtaining the rebound data.
[0042] Operating procedures:
