Description

Technical Field

[0001] This utility model relates to the field of torsion testing technology, and more specifically to an automobile torsion testing machine. Background Technology

[0002] Torsion testing is a test to determine a material's resistance to torque, and it is one of the basic testing methods for the mechanical properties of materials. Torsion testing can determine the strength and plasticity of brittle and ductile materials. Torsion testing is often required for materials used in manufacturing parts that are frequently subjected to torque, such as shafts and springs. For example, in automobile manufacturing, workers need to perform torsion tests on drive shafts. Currently, most workers use automotive torsion testing machines to perform torsion tests on drive shafts.

[0003] Currently, most automotive torsion testing machines require manual handling by operators to move the drive shaft into the machine and connect it. During this process, operators must lift the heavy drive shaft until it is aligned with the mounting slot and inserted. If operators are not skilled enough, they may not be able to connect the drive shaft to the machine in time, which requires a lot of physical effort. Therefore, there is an urgent need to design an automotive torsion testing machine to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automobile torsion testing machine to solve the problem in the above-mentioned background art that during the docking process, the operator needs to lift the heavy drive shaft until it is aligned with the mounting slot of the testing machine and inserted, which is quite laborious.

[0005] This utility model provides the following technical solution: an automobile torsion testing machine, including a base assembly, and also including a torsion device, a clamping assembly, a transmission assembly, and a lifting assembly. The torsion device is fixedly installed on the top of the base assembly, the clamping assembly and the transmission assembly are both slidably installed on the top of the base assembly, and the lifting assembly is disposed inside the transmission assembly.

[0006] The lifting assembly includes a right-angle frame, several pulleys, two fixed blocks, two movable rods, and two sliding blocks. The right-angle frame has two mounting slots on its right-angled inner wall. The pulleys are rotatably installed in the two mounting slots. The two fixed blocks are fixedly installed at the bottom of the right-angle frame. The two movable rods are rotatably installed in the two fixed blocks. The two sliding blocks are slidably installed in the transmission assembly, and the two sliding blocks are rotatably connected to the two movable rods.

[0007] Furthermore, the base assembly includes a base body, a torsion device is fixedly mounted on the top of the base body, and the clamping assembly includes a clamping device that is slidably mounted on the top of the base body.

[0008] Furthermore, the clamping assembly also includes a first motor and a gear. The first motor is fixedly installed on the top of the clamping device, and the gear is rotatably installed on the bottom of the clamping device. The gear is fixedly connected to one end of the output shaft of the first motor. The base assembly also includes several tooth blocks. A square groove is opened on the top of the base body. The gear is adapted to the square groove. The tooth blocks are set on the inner wall of the square groove. The gear is adapted to the tooth blocks.

[0009] Furthermore, the transmission assembly includes a strip plate, a bidirectional threaded rod, and a second motor. The strip plate is slidably mounted on the top of the base body, and a groove is provided on the top of the strip plate. The bidirectional threaded rod is rotatably mounted in the groove. The second motor is fixedly mounted on one side of the strip plate, and one end of the output shaft of the second motor is fixedly connected to the bidirectional threaded rod. Two sliding blocks are slidably mounted in the groove, and both sliding blocks are threadedly slidably sleeved on the outer wall of the bidirectional threaded rod.

[0010] Furthermore, the transmission assembly also includes a support frame, which is fixedly mounted on the top of the strip plate.

[0011] Furthermore, a protective cover is slidably mounted on the top of the base body.

[0012] Furthermore, the clamping device has two rollers fixedly installed at the bottom, four rollers fixedly installed at the bottom of the strip plate, and two strip grooves opened at the top of the base body, with the rollers slidably installed in the strip grooves.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In use, this invention involves lifting the drive shaft and placing it inside the right-angle frame. Supporting the drive shaft, the second motor is then started, driving the bidirectional threaded rod to rotate. This rotation causes two sliding blocks to slide closer together within a groove. The sliding of these blocks in turn causes two movable rods to rotate closer together, lifting two fixed blocks and thus the right-angle frame, raising the drive shaft. Once the drive shaft is aligned with the center line of the torsion device, it is slid towards the torsion device. The drive shaft can slide between several pulleys. After connecting the drive shaft to the torsion device, the first motor is started. The machine drives the gears to rotate. As the gears rotate, they slide along the direction of the tooth blocks, which in turn moves the clamping device closer to the drive shaft. Once the clamping device slides to contact the drive shaft, it fixes the drive shaft to the clamping device. Then, the protective cover slides to the center of the drive shaft, and the torsion test can begin. With the set transmission and lifting components, when loading the drive shaft, the operator only needs to move the drive shaft into the right-angle frame. The second motor will then raise the drive shaft to the same center line as the torsion device, and then slide the drive shaft to connect it with the torsion device. Compared with the existing technology, which requires the operator to lift the drive shaft continuously for connection, this method is much more labor-saving. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0023] An automotive torsion testing machine includes a base assembly 1, a torsion device 2, a clamping assembly 3, a transmission assembly 4, and a lifting assembly 5. The torsion device 2 is fixedly installed on the top of the base assembly 1, the clamping assembly 3 and the transmission assembly 4 are both slidably installed on the top of the base assembly 1, and the lifting assembly 5 is disposed inside the transmission assembly 4.

[0024] The lifting assembly 5 includes a right-angle frame 501, several pulleys 503, two fixed blocks 504, two movable rods 505, and two sliding blocks 506. The right-angle inner wall of the right-angle frame 501 has two mounting slots 502. The several pulleys 503 are rotatably installed in the two mounting slots 502 respectively. The two fixed blocks 504 are fixedly installed at the bottom of the right-angle frame 501. The two movable rods 505 are rotatably installed in the two fixed blocks 504 respectively. The two sliding blocks 506 are slidably installed in the transmission assembly 4, and the two sliding blocks 506 are rotatably connected to the two movable rods 505 respectively.

[0025] In this embodiment, it should be noted that the center of the right-angle frame 501 is on the same plane as the center of the torsion device 2 and the clamping assembly 3.

[0026] Specifically, the base assembly 1 includes a base body 101, the twisting device 2 is fixedly installed on the top of the base body 101, and the clamping assembly 3 includes a clamping device 301, which is slidably installed on the top of the base body 101.

[0027] Specifically, the clamping assembly 3 also includes a first motor 302 and a gear 303. The first motor 302 is fixedly installed on the top of the clamping device 301, and the gear 303 is rotatably installed on the bottom of the clamping device 301. The gear 303 is fixedly connected to one end of the output shaft of the first motor 302. The base assembly 1 also includes several tooth blocks 103. A square groove 102 is provided on the top of the base body 101. The gear 303 is adapted to the square groove 102. The tooth blocks 103 are set on the inner wall of the square groove 102. The gear 303 is adapted to the tooth blocks 103.

[0028] In this embodiment, the first motor 302 is started, which drives the gear 303 to rotate. While rotating, the gear 303 slides along the direction of the tooth block 103, thereby driving the clamping device 301 to move closer to the transmission shaft.

[0029] Specifically, the transmission assembly 4 includes a strip plate 401, a bidirectional threaded rod 403, and a second motor 404. The strip plate 401 is slidably mounted on the top of the base body 101. A groove 402 is provided on the top of the strip plate 401. The bidirectional threaded rod 403 is rotatably mounted in the groove 402. The second motor 404 is fixedly mounted on one side of the strip plate 401. One end of the output shaft of the second motor 404 is fixedly connected to the bidirectional threaded rod 403. Two sliding blocks 506 are slidably mounted in the groove 402, and both sliding blocks 506 are threadedly slidably sleeved on the outer wall of the bidirectional threaded rod 403.

[0030] In this embodiment, the second motor 404 is started, which drives the bidirectional threaded rod 403 to rotate. The rotation of the bidirectional threaded rod 403 can drive the two sliding blocks 506 to slide closer to each other in the slide groove 402 through the thread.

[0031] Specifically, the transmission assembly 4 also includes a support frame 405, which is fixedly installed on the top of the strip plate 401.

[0032] In this embodiment, in the initial state, the right-angle frame 501 is in contact with the top of the support frame 405, and the support frame 405 can provide support for the right-angle frame 501 when the worker places the drive shaft.

[0033] Specifically, a protective cover 6 is slidably installed on the top of the base body 101.

[0034] In this embodiment, the protective cover 6 provides protection during torsion testing, preventing debris from flying everywhere when the drive shaft breaks.

[0035] Specifically, the bottom of the clamping device 301 is fixedly installed with two rollers 7, the bottom of the strip plate 401 is fixedly installed with four rollers 7, and the top of the base body 101 has two strip grooves 104, in which the rollers 7 are slidably installed.

[0036] In this embodiment, the roller 7 at the bottom of the strip plate 401 allows it to slide on the base body 101. When conducting torsion tests on transmission shafts of different lengths, the distance between the right angle frame 501 and the torsion device 2 can be adjusted. The roller 7 at the bottom of the clamping device 301 can guide the clamping device 301 to keep it sliding parallel when the clamping device 301 is driven by the gear 303 to slide.

[0037] Working principle: In use, lift the drive shaft and place it inside the right-angle bracket 501. Support the drive shaft and start the second motor 404 to drive the bidirectional threaded rod 403 to rotate. The rotation of the bidirectional threaded rod 403 drives two sliding blocks 506 to slide closer to each other in the slide groove 402. The sliding of the two sliding blocks 506 will drive the two movable rods 505 to rotate closer to each other. At this time, the two movable rods 505 will push up the two fixed blocks 504, and then push up the right-angle bracket 501, raising the drive shaft. After raising the drive shaft to be on the same center line as the torsion device 2, slide the drive shaft towards the torsion device 2. The drive shaft can slide between several pulleys 503. After connecting the drive shaft to the torsion device 2, start the operation. The first motor 302 drives the gear 303 to rotate. As the gear 303 rotates, it slides along the direction of the tooth block 103, thereby driving the clamping device 301 to move closer to the drive shaft. When the clamping device 301 slides to contact the drive shaft, it fixes the drive shaft to the clamping device 301. Then, the protective cover 6 is slid to the center of the drive shaft, and the torsion test can begin. With the transmission component 4 and the lifting component 5, when loading the drive shaft, the operator only needs to move the drive shaft into the right-angle frame 501. The second motor 404 can then raise the drive shaft to the same center line as the torsion device 2. Then, the drive shaft can be slid to connect with the torsion device 2. Compared with the existing technology, which requires the operator to lift the drive shaft continuously for connection, it is more labor-saving.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
