Description

Technical Field

[0001] This utility model relates to a multi-directional adjustable sample clamping device for flame ablation, belonging to the field of flame ablation testing technology. Background Technology

[0002] Flame ablation apparatuses typically use flames as a heat source and are primarily used for ablation tests on insulation materials, lining materials, and coatings for material screening. They can also be used for ablation and burn-through tests on new materials. A flame ablation apparatus mainly consists of three parts: an ablation stage, an ablation gun, and a control system. The ablation stage is equipped with a sample clamping device, which allows the sample to be fixed directly in front of the ablation gun, maintaining a reasonable distance and angle. This clamping device, located near the flame impact area, needs to possess certain ablation resistance and provide overall support. Existing test clamping devices are only suitable for vertical flame ablation tests on circular samples with a diameter of 4 or 5 mm, thus having the following limitations:

[0003] 1. The flame erosion angle is fixed, making it impossible to perform multi-angle flame purging.

[0004] 2. Flame ablation can only be performed on one side of the sample; corners and edges cannot be tested.

[0005] 3. The shape and size of the sample are limited;

[0006] 4. Large products cannot be tested directly and require sampling or sample preparation according to the equipment. Utility Model Content

[0007] The purpose of this invention is to provide a multi-directional, adjustable, and easy-to-operate sample clamping device for flame ablation.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] This utility model provides a multi-directional adjustable sample clamping device for flame ablation, including a worktable with a flat upper surface, a horizontal guide rail set on the upper surface of the worktable, a sliding support platform slidably connected to the horizontal guide rail, a plate ablation test fixture fixed on the left side of the upper end of the sliding support platform, and an edge ablation test fixture fixed on the right side of the upper end of the sliding support platform.

[0010] The plate ablation test fixture includes a left base and a sample holding frame disposed above the left base. The sample holding frame is a rectangular frame structure that matches the shape of the sample. The inner side of the sample holding frame has a locking groove that matches the rear end of the sample. One side of the locking groove has an opening for connecting a clamping screw. The sample to be tested is inserted into the locking groove of the sample holding frame, and the sample to be tested is fixed in the sample holding frame by the clamping screw. The sample holding frame is connected to the left base through a universal clamping mechanism, so that the test surface of the sample to be tested is aligned with the ablation gun at the required angle.

[0011] The edge ablation test fixture includes a right base and two sets of sample holders positioned above the right base. Each sample holder consists of an adjustable-height support column and two clamping plates positioned at the upper end of the support column. The two ends of the sample to be tested are clamped and positioned between the two clamping plates of the two sets of sample holders. By adjusting the height of the support column in the two sets of sample holders, the edge of the sample to be tested is aligned with the ablation gun at the required angle.

[0012] Work process

[0013] When a certain surface of the sample needs to be subjected to an ablation test, the sample to be tested is inserted into the slot of the sample clamping frame, and the sample to be tested is fixed in the sample clamping frame by the clamping screw; the sample clamping frame is connected to the left base by a universal clamping mechanism, so that the test surface of the sample to be tested is aligned with the ablation gun at the required angle.

[0014] When the edges or corners of the sample need to be ablated, clamp the two ends of the sample to be tested between the two clamping plates of the two sets of sample holders. By adjusting the height of the support columns in the two sets of sample holders, the edges of the sample to be tested are aligned with the ablation gun at the required angle.

[0015] Beneficial effects

[0016] 1. Enables multi-angle flame purging of samples;

[0017] 2. Conduct ablation tests on sharp corners and edges;

[0018] 3. Reduce restrictions on the shape and size of the test specimen;

[0019] 4. Products within a certain size range can be directly tested. Attached Figure Description
