Description

Technical Field

[0001] This utility model relates to the field of engine belt tension testing technology, and in particular to an engine belt tension testing device. Background Technology

[0002] Engine belts are key components of automotive power transmission systems. They are mostly made of rubber and fiber composite materials, which have the characteristics of being resistant to high and low temperatures and tensile strength. They usually connect components such as engine crankshaft, generator, water pump, and air conditioning compressor. Their core function is to transmit the rotational power of the crankshaft to other devices to drive the generator to generate electricity, the water pump to circulate coolant, and the air conditioning compressor to work. During the production process, engine belts are often tested using testing equipment.

[0003] In daily work, it has been found that existing belt tension testing devices have a simple overall testing process, which is not convenient for flexibly adjusting the belt usage under different tensions. They can only complete a single tension setting and test according to a fixed procedure, and cannot dynamically switch tension parameters according to test requirements. This results in a narrow testing scenario coverage, and cannot fully capture the differences in the impact of different tensions on belt transmission efficiency and wear, leading to a single and poor overall testing effect. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the existing technology that it is not convenient to flexibly adjust the use of belts under different tensions, and that the tension setting and testing can only be completed once according to a fixed procedure, and the tension parameters cannot be dynamically switched according to the test requirements. Therefore, an engine belt tension testing device is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an engine belt tension testing device, comprising a workbench, a testing device disposed on the inner wall of the workbench, the testing device comprising a base installed in the inner wall of the workbench, a guide rail fixedly connected to the surface of the base, a sliding plate slidably connected to the surface of the guide rail, two brackets fixedly connected to the surface of the base, and two brackets fixedly connected to the surface of the sliding plate, each of the brackets being provided with a placement shaft and a placement shaft, each of the placement shafts being provided with a mounting part for assembly with the brackets. The belt to be tested is mounted on the support. A transmission component is provided on the surface of the support to control the rotation of the placement shaft. The base is also provided with a control unit to control the movement of the slide plate on the guide rail. A limit component is also provided on the guide rail to limit the belt. During testing, the belt is placed on the placement shaft and the placement shaft, and then the mounting part is used to install the placement shaft and the placement shaft into the support and the support. The control unit can drive the slide plate and the placement shaft to move and adjust the belt tension. The transmission component can drive the placement shaft to rotate and control the belt operation, thereby testing the belt operation under different tension conditions.

[0006] Preferably, the control unit includes two hollow seats fixed on the base, and a transmission screw is rotatably connected to the inner wall of the two hollow seats. The transmission screw is threadedly connected to the inner wall of the slide plate. A drive motor is installed on one side surface of the base, and the output end of the drive motor is fixedly connected to one end of the transmission screw.

[0007] Preferably, the transmission assembly includes a transmission motor mounted on a surface of the bracket, the output end of the transmission motor is fixedly connected to a connector, a protrusion is fixedly connected to the surface of the placement shaft, and the surface of the connector is provided with a snap-fit ​​groove for the protrusion to be inserted. Through the above components, when the protrusion is inserted into the snap-fit ​​groove on the surface of the connector, the transmission motor drives the connector to rotate, and the connector, in conjunction with the protrusion, can drive the placement shaft to rotate.

[0008] Preferably, the mounting part includes two connecting seats that are rotatably connected to the surfaces of the first and second placement shafts. The connecting seats are inserted into the inner walls of the first and second brackets. Two locking blocks are slidably connected to the inner walls of the connecting seats. The inner walls of the first and second brackets are each provided with a slot for inserting the locking blocks. With the above components, the connecting seats of the first and second placement shafts can be inserted into the inner walls of the first and second brackets. Then, the locking blocks are inserted into the slots to complete the installation, which facilitates quick replacement of the belt for testing.

[0009] Preferably, a spring is fixedly connected to the side of the card block corresponding to the inner wall of the connecting seat. There are two springs. Through the above-mentioned components, the springs can drive the card block to reset, thereby improving the stability of the card block when inserted into the card slot.

[0010] Preferably, the card block is L-shaped.

[0011] Preferably, the limiting component includes a limiting seat mounted on a guide rail. The surface of the limiting seat has a groove, and a cover plate is provided above the limiting seat. Multiple bolts are inserted into the inner wall of the cover plate, and the bolts are threadedly connected to the inner wall of the limiting seat. Through the above components, the belt can be placed in the groove, and then the cover plate can be installed on the limiting seat by bolts, so as to limit and restrain the belt.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a detection device and controlling the control unit, the slide plate moves on the guide rail. The second shaft placed on the slide plate moves with the slide plate, thereby adjusting the tension of the belt. In conjunction with the transmission component, the first shaft is controlled to rotate. The first shaft drives the belt and the second shaft to rotate, thus realizing the test. This provides accurate and reliable data support for analyzing the operating status of the belt under different tensions and improves the overall flexibility.

[0013] In this utility model, the mounting part uses a spring and an L-shaped locking block to cooperate. During installation, it is only necessary to push the locking block to compress the spring, insert the connecting seat into the inner wall of bracket one and bracket two, and then release the locking block. The spring can then drive the locking block to reset and lock into the slot, completing the installation of the first and second placement shafts with bracket one and bracket two. During disassembly, it is also only necessary to push the locking block to remove the first and second placement shafts. The whole process does not require complicated tools, which is convenient for changing different belts for testing.

[0014] In this invention, by setting a limiting component, the groove of the limiting seat supports the belt, and with the fixation of the cover plate and bolts, the belt in operation can be effectively restrained, thus improving stability. Attached Figure Description

[0017] Please see Figure 1 - Figure 5 This utility model provides a technical solution: an engine belt tension testing device, including a workbench 1, and a testing device 2 is provided on the inner wall of the workbench 1.

[0018] Specifically, the testing device 2 includes a base 21 installed in the inner wall of the workbench 1. A guide rail 212 is fixedly connected to the surface of the base 21, and a slide plate 22 is slidably connected to the surface of the guide rail 212. Two brackets 29 are fixedly connected to the surface of the base 21, and two brackets 210 are fixedly connected to the surface of the slide plate 22. Each bracket 29 and bracket 210 is provided with a placement shaft 27 and a placement shaft 28. Each placement shaft 27 and placement shaft 28 is provided with a mounting part 211 for assembly with the brackets 29 and 210. A belt to be tested is installed on the placement shaft 27 and placement shaft 28. A transmission component 26 is provided on the surface of the bracket 29 for controlling the rotation of the placement shaft 27 and the test belt. A control part is also provided on the surface of the base 21 for controlling the movement of the slide plate 22 on the guide rail 212. A limit component 23 is also provided on the guide rail 212 for limiting the belt.

[0019] In this implementation scheme: During testing, the belt is placed on placement shaft 27 and placement shaft 28, and then the placement shaft 27 and placement shaft 28 are installed in bracket 29 and bracket 210 through mounting part 211. The control part can drive the slide plate 22 and placement shaft 28 to move and adjust the belt tension. The transmission component 26 can drive placement shaft 27 to rotate and control the belt operation, thereby testing the belt operation status under different tension conditions.

[0020] Specifically, the control unit includes two hollow seats 213 fixed on the base 21. The inner walls of the two hollow seats 213 are rotatably connected to a transmission screw 24. The transmission screw 24 is threadedly connected to the inner wall of the slide plate 22. A drive motor 25 is mounted on one side surface of the base 21. The output end of the drive motor 25 is fixedly connected to one end of the transmission screw 24.

[0021] In this implementation: when the drive motor 25 is turned on, the drive motor 25 can drive the transmission screw 24 to rotate, and the transmission screw 24 can control the slide plate 22 to move on the guide rail 212.

[0022] Specifically, the transmission assembly 26 includes a transmission motor 261 mounted on the surface of the bracket 29. The output end of the transmission motor 261 is fixedly connected to a connector 262. A protrusion 263 is fixedly connected to the surface of the shaft 27. The surface of the connector 262 has a snap-fit ​​groove for the protrusion 263 to be inserted.

[0023] In this embodiment: when the protrusion 263 is inserted into the snap-fit ​​groove on the surface of the connector 262, the drive motor 261 drives the connector 262 to rotate, and the connector 262, in conjunction with the protrusion 263, can drive the placement shaft 27 to rotate.

[0024] Specifically, the mounting part 211 includes two connecting seats 2111 that are rotatably connected to the surfaces of the placement shaft 1 27 and the placement shaft 28. The connecting seats 2111 are inserted into the inner walls of the bracket 1 29 and the bracket 2 210. The inner walls of the connecting seats 2111 are slidably connected to two locking blocks 2112, which are L-shaped. The inner walls of the bracket 1 29 and the bracket 2 210 are provided with slots 2114 for the locking blocks 2112 to be inserted. The corresponding side of the locking block 2112 and the inner wall of the connecting seat 2111 is fixedly connected to a spring 2113, and there are two springs 2113.

[0025] In this implementation scheme: Pushing the locking block 2112 causes the spring 2113 to be stressed, which allows the connecting seat 2111 in the placement shaft 27 and placement shaft 28 to be inserted into the inner wall of the bracket 29 and bracket 210. Then, the locking block 2112 is released, and the spring 2113 drives the locking block 2112 to reset and insert into the slot 2114, thus completing the installation and facilitating quick replacement of the belt for subsequent testing.

[0026] Specifically, the limiting component 23 includes a limiting seat 231 mounted on the guide rail 212. The surface of the limiting seat 231 is provided with a groove 234. A cover plate 232 is provided above the limiting seat 231. Multiple bolts 233 are inserted into the inner wall of the cover plate 232. The bolts 233 are threadedly connected to the inner wall of the limiting seat 231.

[0027] In this embodiment, the belt can be placed in the groove 234, and then the cover plate 232 can be installed on the limiting seat 231 by bolts 233, so as to limit and restrain the belt.

[0028] Working principle: During use, place the belt on the first placement shaft 27 and the second placement shaft 28, then push the locking block 2112 in the connecting seat 2111. The spring 2113 is then stressed, and the connecting seat 2111 in the first placement shaft 27 and the second placement shaft 28 is inserted into the inner wall of the first bracket 29 and the second bracket 210. Then, release the locking block 2112, and the spring 2113 drives the locking block 2112 to reset and insert into the slot 2114, thus completing the installation. At the same time, the protrusion 263 on the surface of the first placement shaft 27 is inserted into the snap-fit ​​groove on the surface of the connector 262. After the belt is assembled, it can be snapped into the groove 234 of the limiting seat 231, and then the cover plate 232 is installed on the limiting seat 231 by bolts 233. The upper part, in conjunction with the groove 234, restricts the belt. During testing, the drive motor 25 is turned on, which drives the transmission screw 24 to rotate. The transmission screw 24 controls the slide plate 22 to move on the guide rail 212, controlling the belt tension. At the same time, when the drive motor 261 drives the connector 262 to rotate, the connector 262, in conjunction with the protrusion 263, can drive the placement shaft 27 to rotate, realizing the testing operation. When disassembling and replacing, simply push the locking block 2112 in the connector 2111, the spring 2113 is stressed, and the locking block 2112 moves out of the slot 2114. Then, the placement shaft 27 and the placement shaft 28 are moved out of the bracket 29 and the bracket 210, and disassembly is complete.
