Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, specifically a tensile testing device for ball sheet processing. Background Technology

[0002] When a basketball is used, it deforms and stretches the outer skin. In order to ensure the tensile performance of the basketball outer skin, tensile tests are often required during the production and processing of the basketball outer skin.

[0003] Most existing tensile testing devices use multiple screws to control clamps to clamp and fix the ball test piece, but this operation is cumbersome and not conducive to improving testing efficiency. Utility Model Content

[0004] To address the problem that the operation of multiple screws is cumbersome and detrimental to improving testing efficiency, the purpose of this utility model is to provide a tensile testing device for ball sheet processing.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: A tensile testing device for ball sheet processing includes a base and a tensile sensor. A column is fixedly mounted on the upper surface of the base. A groove is formed on the outer side of the column. A moving block is slidably engaged inside the groove. A threaded rod is rotatably mounted inside the groove. One end of the threaded rod is threaded through the moving block. A motor is fixedly mounted at the top of the column. The end of the motor output shaft is fixedly connected to the top of the threaded rod. A clamping assembly is arranged in a mirror image between the moving block and the upper surface of the base. Each clamping assembly is equipped with an auxiliary component. The clamping assembly includes a mounting base. Two mounting bases are respectively mounted on the moving block and the base. The tensile sensor is disposed between the moving block and the mounting base. A rotating shaft is rotatably mounted inside the mounting base. A pressure roller is fixedly sleeved on the outer side of the rotating shaft. A handle is fixed to the side, and a return spring is fitted on the outer side of the handle. The handle drives the clamping roller to rotate eccentrically along the rotating shaft, so that the outer side of the clamping roller is away from the inner wall of the mounting base. The spring force of the return spring drives the clamping roller to return to its original position through the handle, so that the clamping roller presses the ball test piece tightly. This makes it easy to clamp the ball test piece. One end of the return spring is fixed to the mounting base with a bolt. An annular groove is opened on the outer side of the handle, and the ring at one end of the return spring is fitted in the annular groove. The annular groove can be used to position the return spring. The central axis of the clamping roller is eccentrically set with the central axis of the rotating shaft. The clamping roller is inclined and fits against the inner wall of the mounting base. The eccentric setting can drive the clamping roller to rotate eccentrically. The upper surface of the base is fixed with anti-slip support feet distributed in a rectangular array. The outer side of the clamping roller is provided with anti-slip texture to prevent slippage between the ball test piece and the clamping roller.

[0006] Preferably, the auxiliary component includes a fixing plate, with one end of each of the two fixing plates facing away from each other fixedly connected to one end of each of the two mounting seats opposite to each other. A protective plate is fixedly provided at the bottom end of the fixing plate, and a positioning plate is provided on the inner side of the protective plate. The outer side of the positioning plate is fitted against the inner wall of the protective plate, and a screw is threaded through the outer side of the protective plate. One end of the screw is rotatably connected to one side of the positioning plate. A knob drives the screw to rotate, causing the screw to move on the protective plate. The screw drives the positioning plate to move, so that the positioning plate fits against the ball skin test piece. This can assist in stretching the ball skin test piece. A knob is fixedly provided at the end of the screw away from the positioning plate, which can be used to easily rotate the screw. The protective plate has a U-shaped structure, which facilitates the insertion of the ball skin test piece.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. By eccentrically rotating the clamping roller through the shaft, the spring force of the return spring drives the clamping roller to reset and press the ball test piece through the handle. Rotating the handle in the opposite direction makes the clamping roller press the ball test piece tightly. At the same time, the elastic force of the ball test piece stretches and the clamping roller presses it further to prevent it from falling off. This can avoid the situation where the adjusting screw clamps slowly, thereby achieving the purpose of fast clamping.

[0009] 2. By turning the knob, the screw is rotated, causing it to move on the protective plate. The screw then moves the positioning plate, making it fit against the ball skin test piece. This prevents the ball from tilting during stretching, thus achieving the purpose of assisting the test. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3 As shown, this utility model provides a tensile testing device for ball sheet processing, including a base 1 and a tensile sensor 3. A column 2 is fixedly mounted on the upper surface of the base 1. A groove 7 is opened on the outer side of the column 2. A moving block 9 is slidably mounted inside the groove 7. A threaded rod 8 is rotatably mounted inside the groove 7. One end of the threaded rod 8 is threaded through the moving block 9. A motor 10 is fixedly mounted on the top of the column 2. The end of the output shaft of the motor 10 is fixedly connected to the top of the threaded rod 8. A clamping assembly 4 is arranged in a mirror image between the moving block 9 and the upper surface of the base 1. Both clamping assemblies 4 have... An auxiliary component 5 is provided; the clamping component 4 includes a mounting base 41, with two mounting bases 41 respectively mounted on the moving block 9 and the base 1. A tension sensor 3 is disposed between the moving block 9 and the mounting base 41. A rotating shaft 42 is rotatably mounted inside the mounting base 41. A pressure roller 43 is fixedly sleeved on the outer side of the rotating shaft 42. A handle 44 is fixedly sleeved on the outer side of the pressure roller 43. A return spring 45 is sleeved on the outer side of the handle 44. The pressure roller 43 and the handle 44 are inclined. The straight-line distance between the axis of the rotating shaft 42 and the mounting base 41 is less than the distance between the axis of the rotating shaft 42 and the farthest point of the pressure roller 43. Figure 3The intermediate pressure roller 43 is in its maximum counterclockwise rotation position. In this position, the pressure roller 43 will no longer rotate counterclockwise, maintaining the locking force on the ball test piece. The handle 44 drives the pressure roller 43 to rotate eccentrically along the shaft 42, moving the outer side of the pressure roller 43 away from the inner wall of the mounting base 41. The return spring 45, through the handle 44, drives the pressure roller 43 to reset, pressing the ball test piece firmly. This facilitates clamping the ball test piece. One end of the return spring 45 is fixed to the mounting base 41 with bolts. A ring is provided on the outer side of the handle 44. The annular groove 46 is used to position the return spring 45. The central axis of the pressure roller 43 and the central axis of the rotating shaft 42 are eccentrically positioned. The pressure roller 43 is inclined and fits against the inner wall of the mounting base 41. The eccentric setting can drive the pressure roller 43 to rotate eccentrically. The upper surface of the base 1 is fixed with anti-slip support feet 6 arranged in a rectangular array. The outer side of the pressure roller 43 is provided with anti-slip texture 47 to prevent slippage between the ball skin test piece and the pressure roller 43.

[0018] The auxiliary component 5 includes a fixing plate 51. The two fixing plates 51 are fixedly connected at opposite ends to the opposite ends of the two mounting seats 41. A protective plate 52 is fixedly provided at the bottom end of the fixing plate 51. A positioning plate 53 is provided on the inner side of the protective plate 52. The outer side of the positioning plate 53 is in contact with the inner wall of the protective plate 52. A screw 54 is threaded through the outer side of the protective plate 52. One end of the screw 54 is rotatably connected to one side of the positioning plate 53. A knob 55 drives the screw 54 to rotate, causing the screw 54 to move on the protective plate 52. The screw 54 drives the positioning plate 53 to move, so that the positioning plate 53 is in contact with the ball skin test piece. This can assist in the stretching of the ball skin test piece. A knob 55 is fixedly provided at the end of the screw 54 away from the positioning plate 53. The screw 54 can be easily rotated by the knob 55. The protective plate 52 has a U-shaped structure, which can facilitate the insertion of the ball skin test piece.

[0019] Working principle: When performing a tensile test, first, the basketball outer skin is made into a test piece. Then, the handle 44 is held and moved in the opposite direction. The handle 44 drives the clamping roller 43 to rotate eccentrically along the rotating shaft 42, so that the outer side of the clamping roller 43 moves away from the inner wall of the mounting base 41. At the same time, the handle 44 stretches the return spring 45, so that the return spring 45 generates elastic force. Next, the two ends of the basketball outer skin test piece are placed between the clamping roller 43 and the mounting base 41 respectively. The elastic force of the return spring 45 drives the clamping roller 43 to return to its original position through the handle 44, so that the clamping roller 43 presses the basketball outer skin test piece. Then, the handle 44 is rotated in the opposite direction to make the clamping roller 43 press the basketball outer skin test piece tightly. This makes it easy to clamp the basketball outer skin test piece. Then, the knob 55 is rotated, and the knob 55 drives the screw 54 to rotate, so that... The screw 54 moves on the protective plate 52, and the screw 54 drives the positioning plate 53 to move, so that the positioning plate 53 is in contact with the ball skin test piece. This can assist the ball skin test piece during stretching and prevent deflection. Then, the motor 10 is started. The end of the output shaft of the motor 10 drives the threaded rod 8 to rotate. The threaded rod 8 drives the moving block 9 to move upward in the slide groove 7. The moving block 9 drives the clamp assembly 4 to perform a tensile test on the ball skin test piece. The elasticity of the ball skin test piece drives the pressure roller 43 to rotate in the opposite direction through the friction with the pressure roller 43, so that the pressure roller 43 further presses the two ends of the ball skin test piece, effectively preventing the ball skin test piece from falling off. At the same time, the tension sensor 3 collects the tension data and transmits it to the background computer for calculation, thereby obtaining the test data.

[0020] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
