[0001] The utility model relates to the technical field of air spring processing and production, in particular to a tensile strength testing device for air spring production. Background Technique

[0002] Air springs are commonly known as air bags, air bag cylinders, leather bag cylinders, etc. An air spring is filled with compressed air in a sealed container, and its elastic effect is realized by the compressibility of the gas. When processing and producing air springs, a tensile strength testing device is required to detect their tensile strength to reduce the failure rate of products.

[0003] However, the existing tensile strength testing devices cannot clamp and fix air springs of different sizes, resulting in the problem of too small application range. Therefore, a tensile strength testing device for air spring production is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tensile strength testing device for air spring production, which solves the problem that the existing tensile strength testing device cannot clamp and fix air springs of different sizes, resulting in too small application range.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A tensile strength testing device for air spring production, including a base and a clamping mechanism arranged outside the base, and the clamping mechanism includes a sliding component and a rotating component;

[0006] The sliding component includes a chute, the outside of the base is fixedly connected with a chute, and the inner wall of the chute is slidably connected with a wedge block;

[0007] The rotating component includes a handle, the outside of the chute is rotatably connected with a handle, one end of the handle is fixedly connected with a first bevel gear, the outer wall of the first bevel gear is meshed with a second bevel gear, one end of the second bevel gear is fixedly connected with a screw rod, and a push block is spirally connected to the outer wall of the screw rod.

[0008] The surface of the base is fixedly connected with a housing, the outside of the housing is rotatably connected with a crank, one end of the crank is fixedly connected with a worm, the outer wall of the worm is meshed with a worm gear, the outer wall of the worm gear is meshed with a rack, the top of the rack is fixedly connected with a movable plate, and the outside of the movable plate is slidably connected with a slide rail.

[0009] Preferably, there are two groups of wedge blocks, and the positional relationship between the two groups of wedge blocks is symmetrical about the midpoint of the chute.

[0010] Preferably, the second bevel gear and the first bevel gear form a rotating structure through the handle.

[0011] Preferably, the surfaces of the first bevel gear and the second bevel gear are perpendicular to each other, and the wedge block forms a sliding structure with the chute through a screw and a push block.

[0012] Preferably, the worm gear forms a rotating structure with the worm through a crank.

[0013] Preferably, the movable plate forms a sliding structure with the slide rail through a rack.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. By setting a rotating handle, it drives the first bevel gear to rotate, and drives the second bevel gear to rotate. At the same time, the screw rotates synchronously, so that the push block slides through the screw, and pushes the wedge block, so that when the wedge block slides in the chute, it performs an operation of clamping and fixing the air spring. On the contrary, when the handle is rotated in the opposite direction, the push block is driven to slide towards the second bevel gear, so that the thrust on the wedge block is released, and the wedge block slides inward by gravity, thereby releasing the fixed state of the air spring, avoiding the problem of too small application range caused by the inability to clamp and fix air springs of different sizes.

[0016] 2. By setting a crank to drive the worm to rotate in the housing, the worm gear rotates following the worm. At the same time, the rack slides up and down in the housing through the worm gear, and drives the movable plate to slide synchronously in the slide rail, so that one end of the air spring that is fixed is matched with the other end that is fixed on the base through the movable plate. Therefore, when the movable plate slides up and down, it will pull the air spring to form a tensile structural relationship. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] As Figures 1-4 shown, a tensile strength testing device for air spring production in the figure includes a base 1 and a clamping mechanism arranged outside the base 1. The clamping mechanism includes a sliding component and a rotating component;

[0025] The sliding component includes a slide groove 2. The outside of the base 1 is fixedly connected with a slide groove 2, and the inner wall of the slide groove 2 is slidably connected with a wedge block 3;

[0026] The rotating component includes a handle 4. The outside of the slide groove 2 is rotatably connected with a handle 4. One end of the handle 4 is fixedly connected with a first bevel gear 5. The outer wall of the first bevel gear 5 is meshed with a second bevel gear 6. One end of the second bevel gear 6 is fixedly connected with a screw 7, and the outer wall of the screw 7 is spirally connected with a pusher block 8.

[0027] Among them, as Figure 2 shown, there are two groups of wedge blocks 3. The positional relationship between the two groups of wedge blocks 3 is symmetrical about the midpoint of the slide groove 2, which is beneficial for the two groups of wedge blocks 3 to form a stable clamping structure and realize the control operation of the sliding of the wedge blocks 3.

[0028] Among them, as Figure 2 shown, the second bevel gear 6 and the first bevel gear 5 form a rotating structure through the handle 4, which is beneficial for the handle 4 to control the rotating state of the second bevel gear 6 and realize the control operation of the rotation of the second bevel gear 6.

[0029] Among them, as Figure 2 shown, the surfaces of the first bevel gear 5 and the second bevel gear 6 are perpendicular to each other. The wedge block 3 and the slide groove 2 form a sliding structure through the screw 7 and the pusher block 8, which is beneficial for the wedge block 3 to be clamped and fixed when sliding outwards or loosened and fixed when sliding inwards, and realize the control operation of the sliding of the wedge block 3.

[0030] Embodiment 2

[0031] As Figure 1 , Figure 3 and Figure 4 shown, a housing 9 is fixedly connected to the surface of the base 1, a crank 10 is rotatably connected to the outer wall of the housing 9, a worm 11 is fixedly connected to one end of the crank 10, a worm gear 12 is meshed with the outer wall of the worm 11, a rack 13 is meshed with the outer wall of the worm gear 12, a movable plate 14 is fixedly connected to the top end of the rack 13, and a slide rail 15 is slidably connected to the outer wall of the movable plate 14.

[0032] Among them, as Figure 4 shown, the worm gear 12 and the worm 11 form a rotating structure through the crank 10, which is beneficial for the crank 10 to control the rotation state of the worm gear 12 and realize the control operation of the rotation of the worm 11.

[0033] Among them, as Figure 4 shown, the movable plate 14 and the slide rail 15 form a sliding structure through the rack 13, which is beneficial for the movable plate 14 to stretch the air spring when sliding and realize the control operation of the sliding of the movable plate 14.

[0034] When in use: First, rotate the handle 4 to drive the first bevel gear 5 to rotate and drive the second bevel gear 6 to rotate. At the same time, the screw 7 rotates synchronously, so that the push block 8 slides through the screw 7 and pushes the wedge block 3 to clamp and fix the air spring when sliding in the chute 2. On the contrary, rotate the handle 4 in the reverse direction to drive the push block 8 to slide towards the second bevel gear 6, loosen the thrust on the wedge block 3, and make the wedge block 3 slide inwards by gravity, so as to loosen the fixed state of the air spring and avoid the problem of too small application range caused by the inability to clamp and fix air springs of different sizes.

[0035] Finally, the crank 10 drives the worm 11 to rotate in the housing 9, the worm gear 12 rotates following the worm 11, and at the same time, the rack 13 slides up and down in the housing 9 through the worm gear 12 and drives the movable plate 14 to slide synchronously in the slide rail 15, so that the fixed end of the air spring is matched with the fixed other end on the base 1 through the movable plate 14. Therefore, when the movable plate 14 slides up and down, it will pull the air spring to form a tensile structural relationship.
