Description

Technical Field

[0001] The utility model relates to the technical field of material performance testing, and particularly relates to an auxiliary testing device for tire assembly performance. Background Art

[0002] The tire assembly performance can be analyzed by a method called the finite element analysis method. Before performing the finite element analysis, it is necessary to conduct uniaxial tensile tests on the rubber compounds used in each part of the tire, then organize and fit the relevant data to obtain the stress-strain relationship curve of the relevant rubber specimens, and then import the obtained data into the finite element analysis software for subsequent analysis work. Therefore, an uniaxial tensile testing device is needed to assist in the analysis of tire assembly performance.

[0003] Since the actual use performance of the assembled tire is affected by various factors, and among them, the temperature factor has an inestimable impact on the actual use performance of the assembled tire. When conducting uniaxial tensile tests on the rubber compounds used in each part of the tire, it is necessary to change the ambient temperature around the rubber compound to simulate the different ambient temperatures when the tire is actually used, so as to obtain test data at different temperatures. Some existing uniaxial tensile testing devices cannot control the ambient temperature around the rubber compound when conducting uniaxial tensile tests on the rubber compounds used in each part of the tire.

[0004] Based on this, an auxiliary testing device for tire assembly performance is now provided, which can eliminate the drawbacks of existing devices. Summary of the Utility Model

Detailed Implementation Manner

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, as Figures 1 - 4 shown, a tire assembly performance auxiliary test device includes an outer shell 100, on the front surface of the outer shell 100, there are provided a display screen 103 and a control box 102. The left inner wall of the outer shell 100 is connected to a fixed base 301. A moving base 302 is slidably provided inside the outer shell 100. An oil cylinder 306 is connected between the moving base 302 and the fixed base 301.

[0026] In this embodiment, a temperature control facility is provided on the upper part of the outer shell 100. The outer shell 100 is slidably connected to a sliding cover 200. The right end surface of the fixed base 301 is connected to a first fixing column 303. The left end surface of the moving base 302 is connected to a second fixing column 304. A tension sensor 305 is respectively connected to the right end surface of the first fixing column 303 and the left end surface of the second fixing column 304. The tension sensor 305 is connected to a clamping device. A material sample at a corresponding position of the tire to be tested is clamped between two clamping devices. Slide the sliding cover 200 to the left to make the material sample in a relatively enclosed environment. Then, adjust the temperature of the environment where the material sample is located through the temperature control facility. Then, use the oil cylinder 306 to perform uniaxial tension. After comparing and processing the data collected by the two tension sensors 305, the test result is obtained.

[0027] In one embodiment, as Figure 3 and Figure 4 shown, the clamping device includes a fixture bottom plate 401 connected to the tension sensor 305. A pair of limit blocks 402 are symmetrically connected to both sides of the fixture bottom plate 401. A fixture top plate 404 is slidably connected between the pair of limit blocks 402. A fixing frame 403 is connected to the upper part of the pair of limit blocks 402. The fixing frame 403 is threadedly connected to a bolt 405.

[0028] In one embodiment, asFigure 1 and Figure 2 As shown in Figure 2 , the temperature control facility includes an air conditioning device 101 connected to the top of the outer shell 100. A through hole 104 is provided at the top of the outer shell 100 at the position where the air conditioning device 101 is located, and a temperature sensor 105 is provided on the left inner wall of the outer shell 100.

[0029] In one embodiment, as Figure 4 As shown in Figure 4 , four bolts 405 are provided on the fixing bracket 403. The spacing between the four bolts 405 is the same. Apply the same torque to each bolt 405 so that the pressure exerted by the fixture on the clamped material is as uniform as possible, so that the tensile force applied to the test material acts uniformly on the clamped part thereof.

[0030] In one embodiment, as Figure 4 As shown in Figure 4 , the bolt 405 is in rotational contact with the fixture top plate 404. During actual use, first screw each bolt 405 up to a suitable position, and then place the end of the material sample at the corresponding position of the tire to be tested between the fixture bottom plate 401 and the fixture top plate 404, and then tighten each bolt respectively. The rotational contact relationship between the bolt 405 and the fixture top plate 404 enables that when screwing each bolt 405, there is no interference between the bolts 405, which is convenient for operation.

[0031] In one embodiment, as Figure 1 As shown in Figure 1 , an observation window 201 is provided on the front surface of the sliding cover 200, which is convenient for observing the state of the test material during the tensile test.

[0032] In one embodiment, as Figure 1 As shown in Figure 1 , handles 202 are provided on the front surface and the right side surface of the sliding cover 200, which is convenient for opening and closing the sliding cover 200.

[0033] In one embodiment, as Figure 1 As shown in Figure 1 , a support wheel fixing block 203 is connected to the lower end of the right side surface of the sliding cover 200, and a support wheel 204 is rotatably connected to the lower end of the support wheel fixing block 203, which improves the stability of the sliding cover 200 when sliding.

[0034] The above embodiments disclose an auxiliary test device for tire assembly performance. When testing the performance of a material sample at a corresponding position of a tire to be tested, first, the bolt 405 is rotated counterclockwise, and under the action of the fixing frame 403, it moves upward, so that there is space for the fixture top plate 404 to move up and down. Then, the end of the test material is placed between the fixture bottom plate 401 and the fixture top plate 404. Then, the bolt 405 is rotated clockwise to press against the fixture top plate 404, so that the fixture top plate 404 presses the test material against the fixture bottom plate 401. After both ends of the test material are fixed by the fixture, the sliding cover 200 is pulled to the left by the handle 202. Then, the target test temperature is set by the control box 102. Under the cooperation of the temperature sensor 105, the control box 102 controls the air-conditioning device 101 to work. The air-conditioning device 101 is communicated with the internal space of the sliding cover 200 through the through hole 104 and adjusts the ambient temperature in the sliding cover 200. After a certain period of time, the test material reaches the same temperature as the ambient temperature. The control box 102 controls the oil cylinder 306 to push the moving base 302 to the right, and the test material is stretched. During this process, the two tension sensors 305 respectively transmit the data to the control box 102, and the control box 102 processes the data and displays it on the display screen 103.

[0035] The above is only the specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
