Description

Technical Field

[0001] This utility model relates to the technical field of plastic cap pull-out force testing, and in particular to a pull-out tooling for testing the pull-out force of plastic caps. Background Technology

[0002] The thermal management desiccant component is a part of the automotive thermal management integrated module, capable of absorbing moisture from the refrigerant. Desiccant granules are loaded into a plastic canister, and the plastic cap and canister are securely fixed together using welding technology to prevent leakage. The strength of the connection between the plastic cap and canister directly affects the desiccant component's moisture absorption performance. Taking the automotive thermal management integrated module as an example, if the plastic cap's pull-out force is insufficient, desiccant granules may leak out. This leakage can then clog the integrated module as the refrigerant circulates, ultimately reducing or even eliminating the module's heat exchange function. Therefore, accurately testing the plastic cap's pull-out force is crucial for ensuring product quality, maintaining corporate reputation, and protecting consumer rights.

[0003] Based on the above, the inventors have discovered the following problem: the current pull-out force testing fixture for plastic caps is difficult to quickly clamp and fix the plastic cylinder of the desiccant component during use, resulting in low testing efficiency and affecting user experience. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pull-out tooling for testing the pull-out force of plastic caps, which can effectively achieve rapid clamping and fixing of the plastic cylinder of the desiccant component, improve testing efficiency, and has high practical value.

[0005] This utility model discloses a pull-out force testing fixture for plastic caps, comprising a base, a top seat, a fixed seat, mounting holes, fixing bolts, locking nuts, clamping seats, a locking mechanism, pull-out hooks, and clamping grooves. A fixed seat is mounted on one side of the top of the base. Mounting holes are provided on both sides of the top of the fixed seat. Fixing bolts are mounted inside the mounting holes, with the bottom ends of the fixing bolts penetrating the bottom of the mounting holes. Locking nuts are mounted on the bottom ends of the fixing bolts. A clamping seat is provided on one side of the fixed seat. Openings are provided at both ends of the fixed seat and the clamping seat. A locking mechanism for locking the clamping seat is fitted onto the outside of the fixing bolts, located inside the openings. Four pull-out hooks are mounted on the bottom of the top seat. The fixing seat and the clamping seat have clamping grooves in the middle of their adjacent sides, and the top seat is located at the top of the clamping grooves. The locking mechanism can be angled and is easy to disassemble and assemble through the installation holes, fixing bolts and locking nuts. The clamping grooves in the middle of their adjacent sides enable the bottle to be clamped. The locking mechanism for locking the clamping seat is sleeved on the outside of the fixing bolts, so that the clamping seat can quickly clamp and fix the bottle. Four pull hooks are installed at the bottom of the top seat. After the pull hooks are inserted into the four pull holes at the top of the plastic cap, they can apply a pull force evenly to the plastic cap, making the pull process more stable and ensuring the accuracy of the test results.

[0006] Preferably, the locking mechanism includes a connecting ring, a screw, a washer, and a knob nut. The inner side of the connecting ring and the outer side of the fixing bolt are sleeved together. A screw is installed on one side of the connecting ring, and a washer and a knob nut are fitted on one end of the screw. By setting up the connecting ring, screw, washer, and knob nut, the distance between the clamping seat and the fixing seat can be easily adjusted by rotating the knob nut, thereby realizing flexible clamping of plastic cylinders of different sizes.

[0007] Preferably, one side of the washer contacts one side of the knob nut, and the other side of the washer contacts the clamping seat on the side away from the fixed seat. By setting the washer, the contact area between the knob nut and the clamping seat can be increased, and the knob nut can be prevented from loosening during use, thus ensuring the stability of clamping.

[0008] Preferably, the base is L-shaped; the L-shaped base increases the stability of the base, enabling it to better withstand the forces generated during the pulling process, reducing the overall shaking and displacement of the tooling, and improving the reliability of the test.

[0009] Preferably, the clamping groove is arc-shaped; by making the clamping groove arc-shaped, it can better fit bottles of different diameters, improving the adaptability of the tooling to bottles of different specifications.

[0010] Preferably, a hydraulic telescopic rod insertion port is provided on the other side of the top of the base, and a first threaded hole is provided on one side of the base. A first locking knob is installed inside the first threaded hole. The hydraulic telescopic rod insertion port, the first threaded hole, and the first locking knob facilitate connection and fixation with the hydraulic telescopic rod, providing power support for the pulling operation. The installation position of the hydraulic telescopic rod can be adjusted and fixed by the first locking knob to ensure accurate application of the pulling force.

[0011] Preferably, the top of the top seat is provided with a tension sensor detection end socket, and a second threaded hole is provided on one side of the top seat. A second locking knob is installed inside the second threaded hole. The tension sensor detection end socket, the second threaded hole, and the second locking knob facilitate connection and fixation with the tension sensor detection end, enabling accurate measurement of the tension during the pulling process and providing data support for the detection of the pull-out force of the plastic cover. At the same time, the position of the tension sensor detection end can be adjusted and fixed by the second locking knob to ensure the accuracy of the measurement.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the installation holes, fixing bolts, and locking nuts enable the locking mechanism to be angle-adjustable, while facilitating the assembly and disassembly of the locking mechanism; the clamping grooves in the middle of the adjacent sides of the fixing seat and the clamping seat enable the bottle body to be clamped; the locking mechanism for locking the clamping seat is sleeved on the outside of the fixing bolt, enabling the clamping seat to quickly clamp and fix the bottle body; and the four pull hooks installed at the bottom of the top seat enable the pull hooks to apply a uniform pull force to the plastic cap after being inserted into the four pull holes at the top of the plastic cap, making the pull process more stable and ensuring the accuracy of the test results.
