Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a high and low temperature test chamber for brake production testing. Background Technology

[0002] After the brake production is completed, high and low temperature tests are usually required to simulate the brake's state in real-world high temperature and extreme cold weather scenarios. By placing the brake in a high and low temperature test chamber and precisely controlling the temperature inside the chamber (usually ranging from -70℃ to +150℃ or wider), the performance stability, material durability and reliability of the brake under high temperature, low temperature and temperature cycling conditions are tested.

[0003] Chinese Patent CN219463457U discloses a high and low temperature test chamber, including a test chamber body, a testing chamber, and an airflow adjustment component. The test chamber body has an internal mounting cavity with multiple air inlets and corresponding return air channels on its inner wall. The return air channels are used to recover high-temperature or low-temperature gases blown out of the air inlets. A gap exists between the outer wall of the testing chamber and the inner wall of the mounting cavity. The product to be tested is placed inside the testing chamber. The airflow adjustment component has air outlets and is fastened to the air inlets. The airflow adjustment component directs the high-temperature or low-temperature gases blown out of the air inlets to various surfaces of the testing chamber through the air outlets. By changing the temperature of the testing chamber, the test temperature of the product inside the chamber is controlled. This heat radiation method of temperature transfer ensures uniform temperature change across all areas of the product under test, thereby improving the quality and accuracy of the test and obtaining accurate test data.

[0004] The above-mentioned high and low temperature test chambers and existing technologies typically insert a tray into a sliding slot inside the test chamber, place the brake on the tray, and close the chamber door to conduct high and low temperature tests. During the test, equipment vibration causes the tray to slide in the slot and the brake to slide on the tray due to lack of fixation, affecting the stability of the test. There is a lack of a corresponding high and low temperature test chamber structure with working stability for brake production testing, which needs to be improved and optimized.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The high and low temperature test chamber for brake production testing proposed in this utility model mainly fixes the tray by setting stop slots on both sides of the limiting slide groove on the inner side wall of the test chamber body and connecting the first spring to squeeze the locking stop block into the locking slot on the positioning tray assembly. The locking stop block is squeezed by the pressing column to unlock it. The tray is provided with multiple sets of fixing pin slots and positioning pins with rubber protrusions are inserted and connected. The brake is placed on the tray and the rubber protrusions are squeezed. The rubber protrusions located at the edge of the brake play a good role in resisting and fixing it.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 5 This utility model provides the following two technical solutions:

[0022] Example 1: A high and low temperature test chamber for brake production testing includes a test chamber body 1, a door 2 hinged to one side of the test chamber body 1, a caster wheel 3 fixedly connected to one side of the test chamber body 1, symmetrical limiting grooves 4 on both sides of the test chamber body 1, a positioning support plate assembly slidably inserted into the limiting groove 4, a stop groove 6 symmetrically provided on both sides of the limiting groove 4, a locking stop 7 slidably inserted into the stop groove 6; a first spring 8 fixedly connected to one side of the locking stop 7, and the other side of the first spring 8 fixedly connected to the inner wall of the stop groove 6.

[0023] In use, open the door 2 of the test chamber body 1, place the brake to be tested on the positioning tray assembly, close the door 2, and perform temperature control to conduct high and low temperature tests. The positioning tray assembly is inserted into the limiting slide groove 4 on the test chamber body 1, and works with the first spring 8 and locking block 7 in the stop groove 6 on both sides of the limiting slide groove 4 to fix the positioning tray assembly in the limiting slide groove 4.

[0024] Example 2: Based on Example 1, the positioning tray assembly includes a tray 501, a locking groove 502, an unlocking groove 503, a fixing pin groove 507, and a positioning pin 508. The tray 501 is slidably inserted into the limiting groove 4. The tray 501 has symmetrically arranged locking grooves 502 on both sides, with locking blocks 7 inserted into each locking groove 502. The tray 501 also has symmetrically arranged unlocking grooves 503 on both sides, with pressing pins 505 inserted into each unlocking groove 503. The tray 501 has a fixing pin groove 507. A positioning pin 508 is inserted into 507; a pressing block 504 is fixedly connected to one side of the pressing column 505, a second spring 506 is fixedly connected to one side of the pressing block 504, and one side of the second spring 506 is fixedly connected to the inner wall of the unlocking groove 503; a third spring 509 is fixedly connected to one side of the positioning pin 508, and one side of the third spring 509 is fixedly connected to the inner wall of the fixing pin groove 507; a rubber protrusion 510 is fixedly connected to one side of the positioning pin 508, and the rubber protrusion 510 is made of high and low temperature resistant silicone rubber.

[0025] In use, when the tray 501 on the positioning tray assembly is inserted into the limiting slide groove 4, it presses against the locking block 7 and the first spring 8 in the stop block groove 6. After insertion, the locking block 7 is inserted into the locking groove 502 under the squeezing action of the first spring 8, fixing the tray 501. When disassembly is required, simply press the pressing post 505 in the unlocking groove 503 to squeeze the squeezing block 504 and squeeze the locking block 7 to disengage it from the locking groove 502, and the tray 501 can be pulled out. The second spring 506 connected to one side of the squeezing block 504 is used to reset the squeezing block 504 without affecting the insertion of the locking block 7 into the locking groove 502. The tray 501 is also provided with multiple sets of fixing pin grooves 507 for insertion. A positioning pin 508 is connected to a third spring 509 on one side. A rubber protrusion 510 is fixedly connected to one side of the positioning pin 508. When the brake is placed on the support plate 501, the brake will squeeze the rubber protrusion 510 and the positioning pin 508. The positioning pin 508 and the rubber protrusion 510 that are close to the edge of the brake are not squeezed by the brake. Under the squeezing action of the third spring 509, the positioning pin 508 and the rubber protrusion 510 extend out of the fixing pin groove 507 and press against and fix the side of the brake. The multiple sets of positioning pins 508 and rubber protrusions 510 can be used to fix brakes of different sizes. The rubber protrusion 510 is made of high and low temperature resistant silicone rubber.
