[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0025] Please see Figures 1-4 The present invention provides the following technical solution: Example 1, see Figure 1 A hose assembly tensile testing device includes a placement component 1, a testing component 3 is disposed above the placement component 1, assembly components 4 are disposed on both sides of the testing component 3, and a pipe assembly 2 is disposed in the middle of the assembly component 4.
[0026] See Figure 4 The pipe assembly 2 includes a hose 22, one end of which is provided with a connecting pipe 21, and the other end of which is provided with a bend 23.
[0027] In actual production, both ends of the hose 22 need to be assembled with the connecting pipe 21 and the bend 23 respectively. During the assembly process, the connecting pipe 21, hose 22, and bend 23 need to be clamped to limit movement and reduce shaking during assembly.
[0028] By setting the placement component 1 to limit the movement of the pipe assembly 2, the shaking of the pipe assembly 2 during assembly is reduced. The specific structure of the placement component 1 is as follows: See Figure 2 The placement component 1 includes a workbench 11, and a limiting seat 13 is provided on the top of the workbench 11.
[0029] See Figure 2 The placement component 1 also includes a first clamping mechanism 12, which is located on the top of the workbench 11, and a connecting pipe 21 is provided in the middle of the first clamping mechanism 12.
[0030] The first clamping mechanism 12 includes a clamping cylinder and a clamping jaw. The output end of the clamping cylinder is connected to the clamping jaw. Activating the clamping cylinder can control the tightening and opening of the clamping jaw. By activating the clamping cylinder, the clamping jaw can be controlled to clamp the connecting pipe 21, thereby reducing the shaking during the assembly of the connecting pipe 21 and the hose 22.
[0031] See Figure 1 and Figure 2 The limiting seat 13 has a limiting groove inside, and a bent tube 23 is provided inside the limiting groove. The shape of the bent tube 23 is adapted to the shape of the limiting groove. A set of pneumatic clamps 14 is provided on each side of the limiting seat 13.
[0032] The limiting groove is irregularly shaped and can be used to limit the bend 23 to reduce the shaking of the bend 23 during assembly. In order to further reduce the shaking of the bend 23, pneumatic clamps 14 are set to limit the bend 23. Two sets of pneumatic clamps 14 are respectively set at both ends of the bend 23. The two sets of pneumatic clamps 14 act on the top of the bend 23 to limit the bend 23 and reduce the shaking of the bend 23 during assembly.
[0033] The specific structure of the pneumatic clamp 14 is as follows: See Figure 3 The pneumatic clamp 14 includes an adjusting cylinder 141, the output end of which is connected to a transmission structure 143, and a pressure plate 144 is provided at the end of the transmission structure 143 away from the adjusting cylinder 141.
[0034] See Figure 3 The pressure plate 144 is used to limit the bending pipe 23. The outer side of the adjusting cylinder 141 is provided with a mounting bracket 142, which is connected to the limiting seat 13.
[0035] The transmission structure 143 is mainly composed of multiple connecting rods. The output end of the adjusting cylinder 141 is connected to the transmission structure 143. When the adjusting cylinder 141 is activated, it drives the transmission structure 143 to move. In turn, the transmission structure 143 drives the pressure plate 144 to rise and fall. When the pressure plate 144 is raised, it is convenient to pick up the bent tube 23. When the pressure plate 144 is pressed down, it is convenient to limit the bent tube 23 and reduce the shaking of the bent tube 23 during assembly.
[0036] See Figure 2 The test component 3 includes an electric slide rail 31, and a second clamping mechanism 32 is provided above the electric slide rail 31.
[0037] See Figure 2 An electric slide rail 31 is located on the top of the workbench 11, and a second clamping mechanism 32 is slidably connected to the top of the electric slide rail 31. A flexible hose 22 is provided in the middle of the second clamping mechanism 32.
[0038] The working principle of the electric slide rail 31 is to use a motor to provide power, and through a reducer, synchronous belt and ball screw, the rotational motion of the motor is converted into linear motion, which drives the slider on the slide rail to move along the track.
[0039] The working principle of the second clamping mechanism 32 is the same as that of the first clamping mechanism 12. In practical applications, the second clamping mechanism 32 can clamp the hose 22. In addition, the electric slide rail 31 can be activated to drive the second clamping mechanism 32 to move horizontally, which makes it easier for the second clamping mechanism 32 to clamp the hose 22 at different positions.
[0040] After the connecting pipe 21, hose 22, and bend 23 are clamped and limited respectively, the hose 22 is assembled with the connecting pipe 21 and bend 23 by setting the assembly component 4. The assembly of the connecting pipe 21, hose 22, and bend 23 is completed first, and then the tensile force of the hose 22 is tested.
[0041] The specific structure of assembly component 4 is as follows: See Figure 2 The assembly component 4 includes a first assembly mechanism 41, and a second assembly mechanism 42 is provided on one side of the first assembly mechanism 41.
[0042] See Figure 2 The first assembly mechanism 41 is located on the top of the workbench 11, and the connection point between the hose 22 and the bend 23 is located in the middle of the first assembly mechanism 41. The second assembly mechanism 42 is located on the top of the workbench 11, and the connection point between the connecting pipe 21 and the hose 22 is located in the middle of the second assembly mechanism 42.
[0043] The first assembly mechanism 41 and the second assembly mechanism 42 have the same structure and function. Both the first assembly mechanism 41 and the second assembly mechanism 42 include a press-fit cylinder, an upper mold, a lower mold, and a sliding structure. The sliding structure consists of a sliding rod and a sliding plate. The sliding plate is sleeved on the outside of the sliding rod. The top of the sliding plate is connected to the output end of the press-fit cylinder, and the bottom of the sliding plate is connected to the upper mold. When the press-fit cylinder is activated, it can drive the sliding plate to move along the sliding rod, thereby realizing the movement of the upper mold position. The bottom of the lower mold is provided with a telescopic cylinder, which can drive the lower mold to move in the vertical direction, making it easy to adjust the position of the lower mold. When the upper mold and the lower mold are closed, the pipe assembly 2 can be press-fitted, thus completing the assembly of the pipe assembly 2.
[0044] The upper and lower molds of the first assembly mechanism 41 are adapted to the connection ports of the hose 22 and the bend 23, and can complete the assembly of the hose 22 and the bend 23. The upper and lower molds of the second assembly mechanism 42 are adapted to the connection ports of the hose 22 and the connecting pipe 21, and can complete the assembly of the hose 22 and the connecting pipe 21.
[0045] The specific assembly process is as follows: First, the operator places the bent pipe 23 into the groove of the limiting seat 13, activates two sets of pneumatic clamps 14, and under the action of the two sets of pneumatic clamps 14, the two pressure plates 144 press down on the top of the bent pipe 23 to limit its movement. Then, the connecting pipe 21 is placed in the position of the first clamping mechanism 12, and the electric slide rail 31 is activated. Driven by the electric slide rail 31, the second clamping mechanism 32 descends and moves closer to the connecting pipe 21. After the position of the second clamping mechanism 32 is adjusted, the operator places the hose 22 in the position of the second clamping mechanism 32, activates the second clamping mechanism 32 to clamp the hose 22, and activates the electric slide rail 31 to move the second clamping mechanism 32 and the hose 22 closer to the connecting pipe 21. During the movement, the connecting pipe 21 and the hose 22 are connected. After the connection is completed, the second assembly mechanism 42 is activated to assemble the connecting pipe 21 and the hose 22. After the assembly of the connecting pipe 21 and the hose 22 is completed, the second clamping mechanism 32 releases the hose 22 and the electric slide rail 31 is activated again. Driven by the electric slide rail 31, the second clamping mechanism 32 moves to the side close to the bend 23 and clamps the hose 22. The first clamping mechanism 12 is activated to release the connecting pipe 21. After the second clamping mechanism 32 clamps the hose 22, the electric slide rail 31 is activated to drive the second clamping mechanism 32 and the hose 22 to continue to approach the bend 23 and complete the docking of the bend 23 and the hose 22. After the bend 23 and the hose 22 are docked, the first assembly mechanism 41 is activated to complete the assembly of the hose 22 and the bend 23.
[0046] After the connecting pipe 21, hose 22, and bend 23 are assembled, the tensile strength of hose 22 needs to be tested.
[0047] The procedure for tensile testing of hose 22 is as follows: The first clamping mechanism 12 is activated to clamp the connecting pipe 21 again. At this time, the bent pipe 23 is limited by the limiting seat 13 and the two sets of pneumatic clamps 14. The connecting pipe 21 and the bent pipe 23 are limited. Then, the telescopic cylinders of the first assembly mechanism 41 and the second assembly mechanism 42 are activated respectively. The telescopic cylinders drive the lower mold away from the hose 22. Then, the second clamping mechanism 32 is activated to clamp the hose 22. The electric slide rail 31 is activated to drive the second clamping mechanism 32 to reciprocate linearly. The hose 22 follows the second clamping mechanism 32 to achieve linear reciprocating motion. The tension test of the hose 22 is completed in the reciprocating motion of the hose 22.
[0048] In the tensile test of hose 22, a data processing device is connected to hose 22. The tensile data of hose 22 can be transmitted to the data processing system through the sensor. The data processing system can process the data collected by the sensor and output a data report to obtain the relevant data content of hose 22 tensile test.
[0049] By setting up placement component 1, testing component 3, and assembly component 4 in coordination, tensile testing of pipe component 2 can be performed directly after the pipe component 2 is assembled, reducing the process of transferring and retesting pipe component 2 and improving the production efficiency of pipe component 2.
[0050] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
