Description

Technical Field

[0001] This utility model relates to the field of elasticity testing technology, and in particular to an automatic elasticity testing device with a rejection mechanism. Background Technology

[0002] Elasticity testing equipment is an instrument specifically used to measure the elasticity, bounce, or recovery ability of materials or products. It is generally used to test the elasticity of elastic components such as springs, rubber, and elastic fiber fabrics. By applying a certain tensile force to the elastic component to deform it, the magnitude of the elasticity is detected. Elasticity testing is an important step in ensuring product safety, excellent performance, and stable quality. However, most existing elasticity testing equipment still has problems that need to be solved.

[0003] Most existing elastic force testing equipment requires clamps or bolts to fix the elastic component before testing it. This requires time and effort to fix and unfix, which affects the overall testing speed. It also requires workers to spend physical strength and energy on repeated operations, increasing labor intensity and labor costs. Therefore, it is necessary to design an automatic elastic force testing device with a rejection mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic elastic force detection device with a rejection mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic elastic force detection device with a rejection mechanism includes a base. Two guide rails are fixedly connected to the top of the base. A movable seat is located on the top of the base, and fixed seats are located at both ends of the movable seat. First rollers are rotatably connected to the fixed seats and are disposed within the guide rails. First fixed rods are fixedly connected to the tops of both fixed seats, passing through the movable seat and slidably connected to it. A common first horizontal plate is fixedly connected to the tops of the two first fixed rods. A first round rod is fixedly connected to the bottom of the first horizontal plate. Two fixed plates are fixedly connected to one side of the movable seat. Second rollers are rotatably connected to the fixed plates. A movable block is located on one side of each second roller. A second fixed rod is fixedly connected to the top of one end of the movable block. A common second horizontal plate is fixedly connected to the tops of the two second fixed rods. A second round rod is fixedly connected to the top of the second horizontal plate. A T-shaped plate is located at the top of the second round rod, and an L-shaped plate is fixedly connected to the bottom of the T-shaped plate. A tensile testing instrument is installed on one side of the L-shaped plate. The testing end of the tensile testing instrument is fixedly connected to the L-shaped plate. Due to the use of a first and second round rod to fix the elastic element, the first round rod can descend a certain distance and pass through one end of the elastic element during its movement. Simultaneously, the second round rod rises and passes through the other end of the elastic element. When the first round rod moves close to the tensile testing instrument, it can rise and move out of the elastic element, and the second round rod will also descend and move out of the elastic element, thus removing the elastic element from the testing equipment. This effectively solves the problem mentioned in the background art that most existing elastic force testing equipment requires the use of clamps or bolts to fix the elastic element before elastic force testing, which requires a certain amount of time and effort to fix and unfix, affecting the overall testing speed and requiring workers to expend physical strength and energy on repeated operations, increasing labor intensity and labor costs. Therefore, this method achieves the technical effect of simple operation, automatic fixing and unfixing of the elastic element, and effectively improving the efficiency of elastic force testing.

[0007] As a further embodiment of this utility model, a guide rod is provided through one end of the movable block, and two springs are provided on the guide rod, with the springs located at the bottom of the movable block.

[0008] As a further embodiment of this utility model, a third fixing rod is fixedly connected to the top of each of the two guide rods, and the two third fixing rods are fixedly connected to the bottom of the T-shaped plate.

[0009] As a further embodiment of this utility model, a U-shaped plate is fixedly connected to the top of the base, and three sliding grooves are provided on the U-shaped plate.

[0010] As a further embodiment of this utility model, a servo motor is fixedly connected to one side of the U-shaped plate, a coupling is fixedly connected to the output end of the servo motor, a drive screw is fixedly connected to the coupling, a screw nut is sleeved on the drive screw, the drive screw and the screw nut are adapted to each other, and the screw nut is fixedly connected to a movable seat.

[0011] As a further embodiment of this utility model, limiting rods are provided at both ends of the movable seat, the limiting rods are fixedly connected to the inner wall of the U-shaped plate, the movable seat is slidably connected to the limiting rods, and the limiting rods are set at the top of the base.

[0012] As a further embodiment of this utility model, a control panel is installed on the top of the base, and the control panel is electrically connected to the tensile tester and the servo motor via wires.

[0013] The beneficial effects of this utility model are as follows:

[0014] By employing a technique that uses a first and a second round rod to fix the elastic element, the first round rod descends a certain distance and passes through one end of the elastic element during its movement, while the second round rod rises and passes through the other end of the elastic element. When the first round rod moves closer to the tensile testing instrument, it can rise and move out of the elastic element, and the second round rod will also descend and move out of the elastic element, thus removing the elastic element from the testing equipment. This effectively solves the problem mentioned in the background art that most existing elastic force testing equipment requires the use of clamps or bolts to fix the elastic element before elastic force testing, which requires a certain amount of time and effort to fix and unfix, affecting the overall testing speed and requiring workers to spend physical strength and energy on repeated operations, increasing labor intensity and labor costs. Thus, this technique achieves the technical effect of simple operation, automatic fixing and unfixing of the elastic element, and effectively improving the efficiency of elastic force testing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4An automatic elastic force detection device with a rejection mechanism includes a base 1. Two guide rails 2 are fixedly connected to the top of the base 1. A movable seat 3 is mounted on the top of the base 1. Fixed seats 4 are mounted at both ends of the movable seat 3. First rollers 5 are rotatably connected to the fixed seats 4 and are disposed within the guide rails 2. First fixing rods 6 are fixedly connected to the tops of both fixed seats 4, passing through the movable seat 3 and slidably connected to it. A common first horizontal plate 7 is fixedly connected to the tops of both first fixing rods 6. A first round rod 8 is fixedly connected to the bottom of the first horizontal plate 7. Two fixed plates 9 are fixedly connected to one side of the movable seat 3. A second roller 10 is rotatably connected to the fixed plate 9. A movable block 11 is provided on one side of the second roller 10. A second fixed rod 12 is fixedly connected to the top of one end of the movable block 11. The top of the two second fixed rods 12 is fixedly connected to the same second horizontal plate 13. A second round rod 26 is fixedly connected to the top of the second horizontal plate 13. A T-shaped plate 17 is provided at the top of the second round rod 26. An L-shaped plate 17 is fixedly connected to the bottom of the T-shaped plate 17. A tensile tester 19 is provided on one side of the L-shaped plate 18. The testing end of the tensile tester 19 is fixedly connected to the L-shaped plate 18. Due to the use of a first round rod and a second round rod to fix the elastic element through the elastic element, the first round rod can descend a certain distance and pass through one end of the elastic element during the movement of the first round rod. At the same time, the second round rod will rise and pass through the other end of the elastic element. When the first round rod moves close to the tensile tester, it can rise and move out of the elastic element, and the second round rod will also descend and move out of the elastic element, so that the elastic element can be removed from the testing equipment. This effectively solves the problem mentioned in the background art that most existing elastic force testing equipment requires the use of clamps or bolts to fix the elastic element before elastic force testing. This requires a certain amount of time and effort to fix and unfix, which affects the overall testing speed and requires workers to spend physical strength and energy on repeated operations, increasing labor intensity and labor costs. Thus, it achieves the technical effect of simple operation, automatic fixing and unfixing of the elastic element, and effectively improving the efficiency of elastic force testing.

[0022] In this embodiment, a guide rod 14 is provided through one end of the movable block 11, and two springs 15 are provided on the guide rod 14. The springs 15 are located at the bottom of the movable block 11. The movable block 11 will move along the guide rod 14. When the movable block 11 descends, it will squeeze the springs 15 to compress the springs 15. The elastic force of the springs 15 can also enable the movable block 11 to return to its original position.

[0023] In this embodiment, the tops of the two guide rods 14 are fixedly connected to the third fixing rods 16, and the two third fixing rods 16 are fixedly connected to the bottom of the T-shaped plate 17.

[0024] In this embodiment, a U-shaped plate 20 is fixedly connected to the top of the base 1. Three sliding grooves 27 are provided on the U-shaped plate 20, and the movable seat 3 and the first fixed rod 6 will move within the sliding grooves 27.

[0025] In this embodiment, a servo motor 23 is fixedly connected to one side of the U-shaped plate 20, and a coupling is fixedly connected to the output end of the servo motor 23. The coupling is fixedly connected to the drive screw 22, and a screw nut 21 is sleeved on the drive screw 22. The drive screw 22 and the screw nut 21 are adapted to each other, and the screw nut 21 is fixedly connected to the movable seat 3.

[0026] In this embodiment, both ends of the movable seat 3 are provided with limiting rods 24. The limiting rods 24 are fixedly connected to the inner wall of the U-shaped plate 20. The movable seat 3 is slidably connected to the limiting rods 24. The limiting rods 24 are set on the top of the base 1. When the movable seat 3 moves, it will move along the limiting rods 24, thereby ensuring the stability of the movable seat 3 when it moves.

[0027] In this embodiment, a control panel 25 is installed on the top of the base 1. The control panel 25 is electrically connected to the tensile tester 19 and the servo motor 23 via wires.

[0028] Working principle: In use, the elastic component to be tested is placed on the second horizontal plate 13 and the movable seat 3. An external power supply is used. The tensile tester 19 and servo motor 23 are started via the control panel 25. The rotation of the output end of the servo motor 23 causes the drive screw 22 to rotate. The drive screw 22 then moves the screw nut 21, which in turn moves the movable seat 3 along the limit rod 24. The movement of the movable seat 3 moves the first fixed rod 6, which in turn moves the fixed seat 4, which in turn moves the first fixed rod 6. As roller 5 moves along guide rail 2, it lowers the first roller 5, which in turn lowers the fixed seat 4. The fixed seat 4 then lowers the first fixed rod 6, which in turn lowers the first horizontal plate 7. The first horizontal plate 7 then lowers the first round rod 8, which hooks onto the elastic element. The movement of movable seat 3 moves the fixed plate 9, which in turn moves the movable block 11. When the movable block 11 is no longer compressed, the contracted spring 15 extends, allowing the movable block 11 to rise. The movable block 11 then moves... The second fixed rod 12 rises, which in turn drives the second horizontal plate 13 to rise. The second horizontal plate 13 then drives the second round rod 26 to rise and hook onto the other end of the elastic element. The second round rod 26 rises and passes through the T-shaped plate 17, causing the first round rod 8 to continue moving, thus pulling the elastic element. The elastic element pulls the second round rod 26, which in turn pulls the T-shaped plate 17. The T-shaped plate 17 then pulls the L-shaped plate 18, which in turn pulls the detection end of the tension tester 19, thereby detecting the elastic force. After completing the elastic force detection, the servo motor... When the output end of machine 23 rotates in the opposite direction, the movable seat 3 returns to its initial position. If the second roller 10 contacts the movable block 11 again and continues to move, it will squeeze the movable block 11 and cause it to descend. The movable block 11 will then squeeze the spring 15 and cause it to descend. At the same time, as the movable block 11 descends, the tubular second round rod 26 descends, the first round rod 8 rises, and the second round rod 26 descends, thus releasing the restriction on the elastic element. Releasing the restriction allows the elastic element to be removed from the testing equipment, and the elastic element that has completed the elasticity test can be taken off.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
