Description

Technical Field

[0001] The utility model belongs to the technical field of tension detection, in particular to a material tension detection device. Background Art

[0002] Material tensile testing usually refers to the testing and evaluation of the performance of materials under tension. Material tensile testing is widely used in materials engineering, manufacturing, construction and other fields. It is one of the important means to evaluate and compare the performance of different materials.

[0003] For example, the utility model disclosed in publication number CN218212337U provides a tensile testing device for raw materials used in engineering testing, which relates to the field of engineering testing equipment. The tensile testing device for raw materials used in engineering testing includes a clamping assembly, which includes a clamping seat and a drive member; the drive member is connected to the clamping seat; at least two clamping heads are slidably mounted on the clamping seat, each having a clamping surface; the clamping seat has a clamping position, and two limit members are passed through the clamping seat, with the two limit members located on either side of the clamping position. A clamping head that matches the material to be tested is selected and slid into the clamping position. The limit members are then passed through the clamping seat to prevent the clamping head from deviating from the clamping position. At this point, the drive member drives the two clamping seats toward each other, and the clamping heads on the two clamping seats can be used to clamp and secure the material to be tested. When the material to be tested changes, simply remove the limit members and then slide and adjust the position of the clamping heads, without having to disassemble the entire clamping assembly. This is convenient and quick, and has a wider range of applications.

[0004] When the above device is in use, the position of the clamping head is adjusted according to the material through the cooperation of the clamping assembly and the limit block. However, when the above device clamps softer rubber materials, due to its characteristics, the top of the rubber sheet will sag under the action of its own gravity, resulting in the clamping block being unable to clamp its top. The operator still needs to manually support it, which is time-consuming and labor-intensive, and reduces the detection efficiency. Therefore, a material tension detection device is proposed to solve the problems raised in the background technology. Utility Model Content

[0008] Preferably, the top ends of the first and second inclined blocks are both inclined, the bottom end of the third inclined block is inclined, and the inclined surfaces of the first and second inclined blocks respectively abut against the inclined surfaces of the two third inclined blocks.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 4As shown, the utility model provides a material tension detection device, including an outer box 1, the top of the outer box 1 is fixedly connected to a hydraulic rod 2, the bottom end of the hydraulic rod 2 is fixedly connected to a detection structure 3, one side of the detection structure 3 is fixedly connected to a limiting block 4, the interior of the outer box 1 is fixedly connected to a cylinder 5, the top of the cylinder 5 is fixedly connected to a limiting plate 6, the surface of the limiting plate 6 is provided with two guide grooves 7, the interior of the outer box 1 is movably connected to a moving block 8 located on the left and right sides of the limiting plate 6, the front and rear sides of the moving block 8 are fixedly connected to a protrusion 9, and the two The interior of each moving block 8 is movably connected to the first oblique block 10 and the second oblique block 11, the interior of the moving block 8 is movably connected to the third oblique block 12, the outside of the third oblique block 12 is movably sleeved with a clamping block 13, the first oblique block 10 is fixedly connected to the side away from the second oblique block 11 with a first connecting rod 15, the end of the first connecting rod 15 away from the first oblique block 10 is hinged to the second connecting rod 16, the top of the second connecting rod 16 is hinged to the third connecting rod 17, and the front and rear sides of the top of the third connecting rod 17 are fixedly connected to a spring piece 18 fixedly connected to the outer box 1.

[0022] The above-mentioned scheme is adopted: the third connecting rod 17 is squeezed downward by the limit block 4, thereby driving the first connecting rod 15 to move toward the moving block 8 through the second connecting rod 16, and then the first connecting rod 15 squeezes the first inclined block 10 and the round rod 19 on one side thereof to move in the same direction, thereby driving the second inclined block 11 to move. While the first inclined block 10 and the second inclined block 11 move, the third inclined block 12 is squeezed upward, and the air inside the clamping block 13 is squeezed out through the square plate, and then the squeezed air forms air pressure on both sides of the rubber sheet, thereby facilitating the detection structure 3 to clamp the top of the rubber sheet.

[0023] like Figures 1 to 4 As shown, the two guide grooves 7 are oriented in opposite directions, and the two protrusions 9 are movably engaged in the inside of the two guide grooves 7. When the limit plate 6 moves upward, the protrusion 9 slides along the trajectory of the guide groove 7 and drives the two moving blocks 8 to move toward each other. The top ends of the first inclined block 10 and the second inclined block 11 are both inclined, and the bottom end of the third inclined block 12 is inclined. The inclined surfaces of the first inclined block 10 and the second inclined block 11 are respectively in contact with the inclined surfaces of the two third inclined blocks 12. A square plate is provided on the top of the third inclined block 12, and the outer wall of the square plate is in contact with the inner wall of the clamping block 13. An air outlet is provided on the top of the clamping block 13.

[0024] The above solution is adopted: an air outlet is opened at the top of the clamping block 13. Its function is that when the third inclined block 12 drives the square plate on its top to move downward under the action of its own gravity, the square plate will suck the external air into the interior of the clamping block 13 through the air outlet, so as to facilitate the next use and ensure the normal operation of the device.

[0025] like Figures 1 to 4As shown, the two clamping blocks 13 are fixedly connected to the opposite sides with gaskets 14, and the gaskets 14 are made of rubber material. An infrared sensor is provided inside the detection structure 3, and the spring 18 is used to squeeze the third link 17 and keep the third link 17 moving upward. After the detection structure 3 moves downward, it drives the limit block 4 to fit the top of the third link 17 and squeeze the third link 17 to move downward. The first inclined block 10 is fixedly connected to the side close to the second inclined block 11 with a round rod 19. The round rod 19 passes through the outer wall of the moving block 8 and extends to the outside of the moving block 8. After the two moving blocks 8 move toward each other, they drive the round rod 19 to abut the outer wall of the second inclined block 11.

[0026] The above solution is adopted: the gasket 14 is made of rubber material. Its function is that, since the rubber material has good elasticity and adhesion, when the rubber sheet is clamped between the two gaskets 14, the rubber material will fit tightly with the rubber sheet with its soft nature and form a certain pressure, thereby making the rubber sheet clamped more stably.

[0027] The working principle and usage process of the present invention are as follows: when the cylinder 5 moves upward, it drives the limit plate 6 to move upward, so that the two protrusions 9 move toward each other along the tracks of the two guide grooves 7, and then drives the two moving blocks 8 to move toward each other. While the moving block 8 moves, the third inclined block 12 drives the clamping block 13 outside it to move in the same direction. When the protrusion 9 slides to the bottom end of the guide groove 7, one end of the round rod 19 abuts against the side wall of the second inclined block 11, and at the same time, the clamping block 13 drives the gasket 14 to abut against the outer wall of the rubber sheet, thereby generating friction, and then fixing the position of the rubber sheet, and then starting the hydraulic rod 2, thereby driving the detection structure 3 and the limit block 4 on one side thereof to move downward, and then the limit block 4 abuts against the top of the third connecting rod 17. At this time, the detection structure 3 continues to move downward. The third connecting rod 17 is squeezed to move downward, and then the first connecting rod 15 is driven to move toward the inside of the moving block 8 through the second connecting rod 16. While the first connecting rod 15 moves, the first inclined block 10 and the round rod 19 on one side thereof are squeezed to move toward the second inclined block 11. Then the first inclined block 10 and the second inclined block 11 squeeze the two third inclined blocks 12, thereby driving the third inclined block 12 to move upward inside the clamping block 13, and then squeezing the air inside the clamping block 13 to the outside. The squeezed air generates air pressure on both sides of the rubber sheet, so that the rubber sheet remains vertical. Then the infrared sensor inside the detection structure 3 checks the position of the rubber sheet and clamps the top of the rubber sheet. Then the hydraulic rod 2 drives the detection structure 3 to move upward, thereby detecting the tension of the rubber sheet.
