Description

Technical Field

[0001] The utility model relates to the technical field of labor protection shoe production, in particular to a labor protection shoe production detection device. Background Art

[0002] Safety shoes need to go through multiple testing processes during production. When testing the impact resistance of safety shoes, a toe impact tester is required. Its main function is to control the rise and fall of the impact head through an electromagnet, and impact the toe guard steel head of the safety shoe at a certain height, and then check whether the toe guard steel head is damaged or deformed, thereby characterizing the impact resistance of the safety shoe.

[0003] When testing safety shoes, existing toe impact testers usually need to place a mold inside the safety shoes to simulate human toes, and use the height difference between the front and back of the mold to determine the damage, thereby determining the impact resistance of the toe. However, when measuring the height of the mold, manual testing is usually used, which makes it difficult to detect the lowest point of the mold after the impact, which may lead to inaccurate test results.

[0021] like Figure 1-6 As shown, the utility model proposes a labor protection shoe production and testing device, comprising a base 1, an impact component 4, a clamping component 5 and a distance measuring component 6. A plurality of brackets 2 are provided at the upper end of the base 1; a mounting box 3 is provided at the upper ends of the plurality of brackets 2. The impact component 4 is arranged on the base 1 and the mounting box 3, and an impact test is performed on the labor protection shoe by a free fall. The clamping component 5 is arranged on the base 1, and clamps the labor protection shoe and drives the labor protection shoe to move.

The impact seat 43 drives the impact hammer 44 to perform free fall motion, so that the impact hammer 44 impacts the toe and the mold, and then the impact resistance of the labor protection shoe is tested by observing the damage to the toe and the height difference between the front and back of the mold.

[0023] Further explanation, the clamping assembly 5 includes a support frame 51 arranged at the upper end of the base 1; a slide groove 52 is provided on the support frame 51, and a fixing plate 53 is symmetrically connected to the lower end of the support frame 51; a threaded rod 1 54 is rotatably connected between the two fixing plates 53; one end of the threaded rod 1 54 is connected to a driving mechanism 2 55, and a clamping member 56 is also threadedly connected thereto; the driving mechanism 2 55 is a motor; and the clamping member 56 is slidably connected to the slide groove 52. The toe of the labor protection shoe can be clamped and driven to move, so that the toe can be removed after impact, which is convenient for measuring the height of the mold. On the other hand, the position of the clamping member 56 can be adjusted according to the size of the toe, so that the toe can be directly below the impact hammer 44.

[0024] Further explanation, the clamping member 56 includes a sliding frame 561; the sliding frame 561 is threadedly connected to the threaded rod 54 and is slidably connected to the slide groove 52; one end of the sliding frame 561 is open, and springs 562 are symmetrically connected to both sides of the opening; the opposite ends of the two groups of springs 562 are respectively connected to clamping plates 563. Shoes of different shapes and sizes can be stably clamped, and the application is more flexible and extensive.

[0025] Further explanation: the clamping plate 1 563 is arc-shaped, so that the clamping plate 1 563 can better fit the arc of the toe of the shoe, and prevent the toe from falling off the clamping member 56.

[0026] Further explanation, the distance measuring assembly 6 includes a threaded rod 61 rotatably connected to the upper end of the support frame 51 and a sliding column 62 connected to the upper end of the support frame 51; the upper ends of the threaded rod 61 and the sliding column 62 are jointly provided with a limit plate 64; the limit plate 64 is rotatably connected to the threaded rod 61; one end of the threaded rod 61 is connected to a driving mechanism 3 63; the driving mechanism 3 63 is a motor; the threaded rod 61 and the sliding column 62 are also jointly provided with a lifting rod 65; the lifting rod 65 is threadedly connected to the threaded rod 61 and slidably connected to the sliding column 62; one end of the lifting rod 65 is connected to a clamping plate 2 66, and the upper end is connected to a fixed column 67; the upper end of the fixed column 67 is connected to a telescopic mechanism 68; the telescopic mechanism 68 is a cylinder; the telescopic end of the telescopic mechanism 68 is connected to a laser rangefinder 69; the detection head of the laser rangefinder 69 is set downward. The height of the lifting rod 65 and the clamping plate 2 66 can be adjusted according to the thickness of the soles of different labor protection shoes. The laser rangefinder 69 can measure the height of the mold twice before and after the impact, and the damage of the mold can be judged by the height difference between the two measurements. In addition, the laser rangefinder 69 can follow the telescopic end of the telescopic mechanism 68 to find the lowest point of the mold after the impact, making the impact detection result more accurate and the detection process more convenient and quick.

[0027] To further illustrate, the clamping assembly 5 and the distance measuring assembly 6 are horizontally centered; one open end of the sliding frame 561 is opposite to the clamping plate 2 66 .

[0028] The working principle of the utility model is as follows: when working, first place the mold in the clamping plate 2 66, so that the bottom of the clamping plate 2 66 is flush with the bottom of the mold, and then start the telescopic mechanism 68 to drive the laser rangefinder 69 to extend to measure the height of the mold before impact. Then put the toe into the clamping plate 1 563 on both sides, so that the spring 562 pushes the clamping plate 1 563 to clamp the toe. Then start the driving mechanism 2 55 to drive the threaded rod 1 54 to rotate, thereby driving the clamping member 56 to move along the slide 52, so that the toe moves to the bottom of the impact hammer 44, and the clamping plate 2 66 enters the inside of the toe. Then start the driving mechanism 3 63 to drive the threaded rod 2 61 to rotate, so that the lifting rod 65 and the clamping plate 2 66 are lifted and lowered along the threaded rod 2 61 and the slide column 62, so that the bottom of the mold is flush with the bottom of the clamping plate 2 66 and the upper surface of the toe. Then, the rotating hook 45 is rotated to disengage the impact seat 43 and the sliding seat 42, so that the impact seat 43 drives the impact hammer 44 to fall freely and hit the toe of the shoe. After the impact is completed, the sliding seat 42 is pulled downward again, and the rotating hook 45 is engaged with the connecting column 46, and then the driving mechanism 1 48 is started to drive the rotating shaft 47 to rotate, thereby driving the sliding seat 42 and the impact seat 43 to rise. Then, the driving mechanism 2 55 is started to make the clamping member 56 drive the toe of the shoe to move away, and finally the telescopic mechanism 68 and the laser rangefinder 69 are started. The laser rangefinder 69 can move with the telescopic end of the telescopic mechanism 68 to find the lowest point of the mold after the impact. The height difference between the two measurements can be used to determine the damage of the mold, thereby determining the impact resistance of the toe of the shoe.
