Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, specifically to a heat flow meter testing fixture. Background Technology

[0002] A heat flow meter test fixture is an auxiliary tool used for heat flow meter testing. Generally, the test object is fixed onto the test fixture, and then the protective cover at the bottom of the heat flow meter test head is moved to cover the test fixture before the object is tested.

[0003] The heat flow meter testing fixture can fix the object and then test it through the heat flow meter. When using the existing heat flow meter testing fixture, the object needs to be clamped and fixed by the limiting mechanism, but the object cannot be flipped or adjusted. The bottom of the object is difficult to contact the airflow ejected by the heat flow meter, so the test effect is poor. Utility Model Content

[0004] The purpose of this invention is to provide a heat flow meter testing fixture to solve the problem mentioned in the background art that the existing heat flow meter testing fixtures are difficult to adjust for fixed objects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat flow meter testing fixture, comprising: a base plate and a clamping mechanism, wherein the top of the base plate is slidably connected to a movable frame via a slide rail assembly.

[0006] A clamping mechanism is provided on one side of the movable frame. The clamping mechanism includes a connecting rod that is movably connected to the movable frame via a bearing. A rotating frame is fixedly connected to one end of the connecting rod. A bidirectional threaded rod a is movably connected to the inside of the rotating frame via a bearing. A clamping block is threaded to the outer side of the bidirectional threaded rod a. An adjustment mechanism is provided inside the base plate.

[0007] Specifically, rotating the bidirectional threaded rod a can drive the two sets of moving frames to move closer to each other or further apart.

[0008] Preferably, a rubber pad is fixedly connected to one side of the clamping block, and the outer side of the clamping block is slidably connected to the rotating frame.

[0009] Specifically, the rubber pads prevent the clamping blocks from pinching or damaging objects.

[0010] Preferably, the movable frame has an internal threaded connection of a bidirectional threaded rod b, and the two ends of the bidirectional threaded rod b are movably connected to the base plate through bearings.

[0011] Specifically, the bidirectional threaded rod b can drive the clamping block to move in a relative direction.

[0012] Preferably, the adjusting mechanism includes a synchronous pulley a fixedly connected to one end of the connecting rod, and a synchronous belt is sleeved on the outer side of the synchronous pulley a.

[0013] Preferably, a timing pulley b is sleeved on one side of the timing belt, and a connecting shaft is fixedly connected to one side of the timing pulley b.

[0014] Specifically, the rotating frame can be driven to rotate by the synchronous pulley a, the synchronous belt and the synchronous pulley b, thereby adjusting the angle of the fixed object.

[0015] Preferably, one end of the connecting shaft is movably connected to the movable frame via a bearing, and a rectangular rod is slidably connected inside both the connecting shaft and the synchronous wheel b. A circular hole is provided at the bottom of the movable frame for the rectangular rod to rotate.

[0016] Specifically, the rectangular rod is used to drive the two sets of synchronous pulleys b to rotate synchronously.

[0017] Preferably, one end of the rectangular rod is fixedly connected to a drive shaft, the outer side of the drive shaft is movably connected to the base plate via a bearing, and one end of the drive shaft is fixedly connected to a worm gear.

[0018] Preferably, a worm is meshed with the outer side of the worm gear, and the outer side of the worm is movably connected to the base plate via a bearing.

[0019] Specifically, rotating the worm gear can drive the worm wheel to rotate, which in turn drives the transmission shaft and the rectangular rod to rotate.

[0020] Compared with existing technologies, the advantages of this heat flow meter testing fixture are:

[0021] 1. In this heat flow meter testing fixture, when fixing the test object, rotating the bidirectional threaded rod b causes the bidirectional threaded rod b to engage with two sets of moving frames, thereby driving the two sets of moving frames to move in opposite directions. When the moving frames move to a position close to the volume of the test object, the test object is fed between multiple sets of clamping blocks. Then, rotating the bidirectional threaded rod a causes the bidirectional threaded rod a to engage with the two sets of clamping blocks, thereby driving the two sets of clamping blocks to move closer together and fix the test object. In this way, test objects of different volumes can be easily fixed onto the testing fixture.

[0022] 2. In this heat flow meter testing fixture, when adjusting the angle of the test object, the worm gear meshes with the worm wheel, causing the worm wheel to rotate. The worm wheel then drives the transmission shaft and rectangular rod on one side to rotate. The rectangular rod in turn drives two sets of synchronous pulleys b to rotate. The synchronous pulleys b drive the synchronous pulleys a to rotate via the outer synchronous belt, causing the connecting rod on one side of the synchronous pulleys a to rotate as well. The connecting rod drives the rotating frame at one end to rotate. Since the two sets of synchronous pulleys b rotate synchronously, the two sets of rotating frames also rotate synchronously, thereby adjusting the angle of the clamped object so that the bottom of the object can contact the heat flow meter. In this way, the angle of the object fixed on the heat flow meter testing fixture can be easily adjusted. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 This utility model provides a technical solution: a heat flow meter testing fixture, including: a base plate 1 and a clamping mechanism 3, wherein the top of the base plate 1 is slidably connected to a movable frame 2 via a slide rail assembly.

[0030] A clamping mechanism 3 is provided on one side of the movable frame 2. The clamping mechanism 3 includes a connecting rod 305 that is movably connected to the movable frame 2 via a bearing. One end of the connecting rod 305 is fixedly connected to a rotating frame 301. A bidirectional threaded rod a302 is movably connected inside the rotating frame 301 via a bearing. A clamping block 303 is threadedly connected to the outer side of the bidirectional threaded rod a302. An adjustment mechanism 4 is provided inside the base plate 1.

[0031] A rubber pad 304 is fixedly connected to one side of the clamping block 303, and the outer side of the clamping block 303 is slidably connected to the rotating frame 301; the internal thread of the movable frame 2 is connected to a bidirectional threaded rod b306, and the two ends of the bidirectional threaded rod b306 are movably connected to the base plate 1 through bearings. The bidirectional threaded rod a302 and the clamping block 303 form a threaded transmission structure, and the rotating frame 301 and the clamping block 303 form a sliding structure.

[0032] In practical implementation, when fixing the test object, the heat flow meter testing fixture rotates the bidirectional threaded rod b306, which engages with the two sets of moving frames 2 through threaded transmission, thereby causing the two sets of moving frames 2 to move in opposite directions. When the moving frames 2 move to a position close to the volume of the test object, the test object is fed between multiple sets of clamping blocks 303. Then, the bidirectional threaded rod a302 is rotated, which engages with the two sets of clamping blocks 303 through threaded transmission, thereby causing the two sets of clamping blocks 303 to move closer to each other and fix the test object. The rubber pad 304 can prevent the test object from being pinched. In this way, the above operation can easily fix test objects of different volumes onto the testing fixture.

[0033] Please see Figures 1-4 The adjusting mechanism 4 includes a synchronous pulley a401 fixedly connected to one end of the connecting rod 305, a synchronous belt 402 sleeved on the outer side of the synchronous pulley a401; a synchronous pulley b403 sleeved on one side of the synchronous belt 402, and a connecting shaft 404 fixedly connected to one side of the synchronous pulley b403; one end of the connecting shaft 404 is movably connected to the movable frame 2 via a bearing; rectangular rods 405 are slidably connected inside both the connecting shaft 404 and the synchronous pulley b403; and the bottom of the movable frame 2 has an opening for the rectangular rods 405 to rotate. A movable circular hole; one end of the rectangular rod 405 is fixedly connected to a drive shaft 406, the outer side of the drive shaft 406 is movably connected to the base plate 1 through a bearing, and one end of the drive shaft 406 is fixedly connected to a worm gear 407; the outer side of the worm gear 407 is meshed with a worm 408, the outer side of the worm 408 is movably connected to the base plate 1 through a bearing, and the worm gear 407 and the worm 408 form a meshing transmission structure. The synchronous pulley b403 and the connecting shaft 404 are both provided with rectangular grooves that match the rectangular rod 405.

[0034] In practical implementation, when adjusting the angle of the test object, the heat flow meter testing fixture engages the worm gear 408 with the worm wheel 407, causing the worm wheel 407 to rotate. The worm wheel 407 then drives the transmission shaft 406 and rectangular rod 405 on one side to rotate. The rectangular rod 405 then drives two sets of synchronous pulleys b403 to rotate. The synchronous pulleys b403 drive the synchronous pulley a401 to rotate via the outer synchronous belt 402, causing the connecting rod 305 on one side of the synchronous pulley a401 to rotate as well. The connecting rod 305 then drives a... The rotating frame 301 at the end rotates. Since two sets of synchronous wheels b403 rotate synchronously, the two sets of rotating frames 301 also rotate synchronously, thereby adjusting the angle of the clamped object so that the bottom of the object can contact the heat flow meter. Since the moving frame 2 has a circular hole for the rectangular rod 405 to rotate, the rectangular rod 405 will not interfere with the moving frame 2 when rotating, and the moving frame 2 will not interfere with the rectangular rod 405 when moving. In this way, the angle of the object fixed on the heat flow meter testing fixture can be easily adjusted through the above operation.

[0035] In summary: When using a heat flow meter testing fixture, the test object is first fixed to the testing fixture using the clamping mechanism 3. Then, the movable heat flow meter is used to shield the top of the testing fixture before testing the object begins. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
