Description

Technical Field

[0001] This utility model belongs to the field of mechanical experiment technology, and specifically relates to a multifunctional mechanical experiment platform. Background Technology

[0002] Mechanics experiments are a fundamental component of science and engineering education and engineering research. Their core purpose is to verify theoretical models, analyze material properties, and explore mechanical laws through experimental methods.

[0003] The current announcement is for Chinese utility model patent CN205426690U, which discloses a bending test device. The device is provided with a hinged left support and a right support, which are used to fix the two sides of the flexible test piece respectively. The bending test device also includes a driving device connected to the left support and / or the right support. Under the drive of the driving device, the left support moves closer to or away from the right support, so that the flexible test piece bends towards the hinge position of the left and right supports during the test.

[0004] This patent can only measure the curvature of the object under test, but cannot measure the torsional shear stress of the object under test. Different equipment is needed to test the bending resistance and torsional shear stress of the object under test separately. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional mechanical experimental platform, which solves the problem that the existing bending test device can only measure the bending degree of the object under test, but cannot measure the torsional shear stress of the object under test, and requires different devices to test the bending resistance and torsional shear stress of the object under test separately.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multifunctional mechanical experimental platform, including a base, on which a support arm is fixedly mounted, the number of support arms being two and symmetrically arranged, a cross arm being fixedly mounted at the upper end of the support arm, an installation mechanism being mounted on the cross arm, a slide being fixedly mounted between the two support arms, and a pressure mechanism being mounted on the slide.

[0007] The installation mechanism includes a mounting base, a moving component, a mounting hole, a circular tube to be tested, a limiting hole, a limiting rod, and a connecting arm. The mounting base is disposed on the horizontal arm and is slidably connected to the horizontal arm via the moving component. The mounting hole is opened on the mounting base, and the circular tube to be tested is disposed inside the mounting hole. The limiting hole is opened at the lower part of the mounting hole, and the limiting rod is disposed inside the limiting hole. The connecting arm is fixedly connected to the other end of the circular tube to be tested by bolts.

[0008] Using the above technical solution, by setting a base, support arm, cross arm, mounting mechanism, slide table, and pressure mechanism, in use, the base first installs and fixes the support arm, the support arm installs and fixes the cross arm, then the mounting mechanism installs and fixes the object to be tested and moves the object to be tested, and then the pressure mechanism moves on the slide table until it reaches the appropriate position according to the length of the object to be tested. When the mounting mechanism moves the object to be tested directly above the pressure mechanism, the compressive strength test of the object to be tested can be performed. When the mounting mechanism moves the object to be tested out of alignment with the pressure mechanism, the test of the object to be tested can be performed. The torsional shear stress test involves a mounting mechanism comprising a mounting base, a moving component, mounting holes, a test tube, a limiting hole, a limiting rod, and a connecting arm. In use, the mounting holes are first used to install the test tube. Then, the limiting rod is inserted into the limiting hole, and the test tube is fixed in the mounting hole by the compression of the limiting rod. Next, the moving component moves the test tube directly above the pressure block, allowing for a bending test. When the moving component causes the test tube to misalign with the pressure block, the pressure block transmits force to the test tube through the connecting arm, at which point a torsional shear stress test can be performed on the test tube.

[0009] Furthermore: the pressure mechanism includes a movable seat, a movable rod, a transmission rod, a first handle, a pressure block, a pressure sensor, and a strain gauge. The movable seat is mounted on a slide table, the movable rod extends vertically through the movable seat, and the transmission rod extends horizontally through the movable seat. The movable rod and the transmission rod are connected within the movable seat via a gear and rack structure. The first handle is fixedly mounted at one end of the transmission rod, the pressure block is fixedly mounted at the upper end of the transmission rod, the pressure sensor is mounted on the pressure block, and the strain gauge is wound around the cylindrical tube to be tested.

[0010] Using the above technical solution, by setting up a movable seat, a movable rod, a transmission rod, a first handle, a pressure block, a pressure sensor, and a strain gauge, in use, the movable seat first installs the movable rod and the transmission rod. Since the transmission rod and the movable rod are connected by a gear and rack structure, when the first handle drives the transmission rod to rotate, the movable rod can move. Then, the pressure block and the pressure sensor come into contact with the circular tube to be measured or the connecting arm and provide pressure. Then, the strain gauge can detect the changes in the circular tube to be measured.

[0011] Furthermore: the moving component includes a sliding groove, a connecting plate, and a cylinder. The sliding groove is formed on the cross arm, the connecting plate is fixedly mounted on the mounting base, and the connecting plate is slidably connected in the sliding groove. The cross-sections of the connecting plate and the sliding groove are both convex. The cylinder is fixedly mounted at one end of the cross arm, and the telescopic shaft of the cylinder is slidably connected to the connecting plate.

[0012] By adopting the above technical solution, by setting a sliding groove, a connecting plate and a cylinder, the connecting plate is connected to the mounting base during use, and then the cylinder can drive the connecting plate to move in the sliding groove, thereby enabling the mounting base to drive the round tube to be tested to move.

[0013] Furthermore: a fixed plate is fixedly installed at one end of the slide table, a lead screw is rotatably connected to the support arm, the lead screw passes through the movable seat and the fixed plate, the lead screw is threadedly rotatably connected to the movable seat, and a second handle is fixedly installed at one end of the lead screw.

[0014] By adopting the above technical solution, by setting a fixed plate, a lead screw, and a second handle, in use, the fixed plate first cooperates with the support arm to enable the lead screw to rotate. Since the lead screw is threadedly connected to the moving seat, when the lead screw rotates, it can drive the moving seat to move, and then move the pressure block to a suitable position according to the length of the round tube to be measured.

[0015] Furthermore: a mounting block is provided on the cross arm, a through groove is provided in the mounting block, a beam to be tested is provided inside the through groove, the beam to be tested is detachably installed in the through groove by bolts, and strain gauges are wound on the surface of the beam to be tested.

[0016] Using the above technical solution, by setting up an installation block, a through groove and a beam to be tested, when it is necessary to conduct a bending test on the beam to be tested, the beam to be tested is first fixed in the through groove of the installation block, and then the moving seat is moved to the bottom of the beam to be tested, and then the bending test is conducted on the beam to be tested through the pressure block and the sensor.

[0017] Furthermore, the slide is provided with scale lines.

[0018] By adopting the above technical solution and setting scale lines, the moving base can be easily moved to the corresponding area by comparing the length of the tube to be measured with the scale lines during use.

[0019] Furthermore: a metal beam bending test mechanism and a compressive strength measurement mechanism are provided below the moving rod, and the metal beam bending test mechanism and the compressive strength measurement mechanism are provided corresponding to the pressure mechanism;

[0020] The compressive strength measuring mechanism includes a mounting plate, a test object, and clamping plates. The mounting plate is fixedly mounted on the base, and the test object is mounted on the mounting plate. There are two sets of clamping plates. One set of clamping plates is fixed on the mounting plate to clamp the lower end of the test object, and the other set of clamping plates is detachably connected to the moving rod to clamp the upper end of the test object.

[0021] By adopting the above technical solution and setting up a metal beam bending test mechanism, bending tests can be performed on the metal beam during use, thereby improving the versatility of the equipment.

[0022] Furthermore, both the moving rod and the transmitting rod are configured not to contact the lead screw.

[0023] By adopting the above technical solution, the relationship between the moving rod and the transmission rod and the lead screw is set so that the moving rod and the transmission rod are not in contact with the lead screw, thus avoiding mutual interference during their operation.

[0024] In summary, this utility model has the following beneficial effects:

[0025] By setting up an installation mechanism, during use, the installation hole can first be used to install the test tube, then the limiting rod is inserted into the limiting hole, and the test tube is fixed in the installation hole by the compression of the limiting rod. Then, when the moving component moves the test tube to be directly above the pressure block, a bending test can be performed. When the moving component causes the test tube to be misaligned with the pressure block, the pressure block will transfer the force to the test tube through the connecting arm, and a torsional shear stress test can be performed on the test tube.

[0026] By setting up a pressure mechanism, during use, the moving seat first installs the moving rod and the transmission rod. Since the transmission rod and the moving rod are connected by a gear and rack structure, when the first handle drives the transmission rod to rotate, the moving rod can move. Then, the pressure block and pressure sensor come into contact with the test tube or connecting arm and provide pressure. Then, the strain gauge can detect the changes in the test tube.

[0027] Based on the above improvements, the overall technical effect achieved by this device is that it can perform bending and torsional shear stress tests on the test tube, avoiding the waste of a lot of equipment costs. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0037] Please see Figures 1-7 The present invention provides a technical solution: a multifunctional mechanical experimental platform, including a base 1, a support arm 2 fixedly mounted on the base 1, two support arms 2 arranged symmetrically, a cross arm 3 fixedly mounted on the upper end of the support arm 2, an installation mechanism 4 mounted on the cross arm 3, a slide table 14 fixedly mounted between the two support arms 2, and a pressure mechanism 5 mounted on the slide table 14.

[0038] The mounting mechanism 4 includes a mounting base 401, a moving component 402, a mounting hole 403, a circular tube to be tested 404, a limiting hole 405, a limiting rod 406, and a connecting arm 407. The mounting base 401 is mounted on the horizontal arm 3 and is slidably connected to the horizontal arm 3 via the moving component 402. The mounting hole 403 is opened on the mounting base 401, and the circular tube to be tested 404 is located inside the mounting hole 403. The limiting hole 405 is opened at the lower part of the mounting hole 403, and the limiting rod 406 is located inside the limiting hole 405. The connecting arm 407 is fixedly connected to the other end of the circular tube to be tested 404 by bolts.

[0039] By setting up a base 1, a support arm 2, a cross arm 3, a mounting mechanism 4, a slide table 14, and a pressure mechanism 5, in use, the base 1 first installs and fixes the support arm 2, the support arm 2 installs and fixes the cross arm 3, then the mounting mechanism 4 installs and fixes the object to be tested and moves the object to be tested, and then the pressure mechanism 5 moves on the slide table 14 until it moves to the appropriate length according to the length of the object to be tested. When the mounting mechanism 4 moves the object to be tested directly above the pressure mechanism 5, the compressive strength test of the object to be tested can be performed. When the mounting mechanism 4 moves the object to be tested out of alignment with the pressure mechanism 5, the torsional shear stress test of the object to be tested can be performed.

[0040] In use, the mounting hole 403 is first installed to install the test tube 404. Then, the limiting rod 406 is inserted into the limiting hole 405. Through the compression of the limiting rod 406, the test tube 404 is fixed in the mounting hole 403. Then, the moving component 402 moves the test tube 404 to be directly above the pressure block 505, and a bending test can be performed. When the moving component 402 causes the test tube 404 to be misaligned with the pressure block 505, the pressure block 505 transmits the force to the test tube 404 through the connecting arm 407. At this time, a torsional shear stress test of the test tube 404 can be performed.

[0041] refer to Figure 2 The pressure mechanism 5 includes a movable base 501, a movable rod 502, a transmission rod 503, a first handle 504, a pressure block 505, a pressure sensor 506, and a strain gauge 507. The movable base 501 is mounted on the slide table 14. The movable rod 502 extends vertically through the movable base 501, and the transmission rod 503 extends horizontally through the movable base 501. The movable rod 502 and the transmission rod 503 are connected within the movable base 501 by a gear and rack structure. The rotational motion of the gear on the transmission rod 503 drives the rack to move the movable rod 502. The moving rod 502 moves linearly. The first handle 504 is fixedly installed at one end of the transmission rod 503. The pressure block 505 is in two sets and is fixedly installed at the upper and lower ends of the transmission rod 503 respectively. The pressure sensor 506 is installed between the pressure block 505 and the moving rod 502. The strain gauge 507 is wound and connected to the circular tube 404 to be tested (the strain gauge 507 is a direct application of this application and is not within the scope of protection of this application. It can be a resistance strain gauge. For the specific principle of the resistance strain gauge, please refer to: CN105241371B).

[0042] By setting up a movable base 501, a movable rod 502, a transmission rod 503, a first handle 504, a pressure block 505, a pressure sensor 506, and a strain gauge 507, in use, the movable base 501 first installs the movable rod 502 and the transmission rod 503. Since the transmission rod 503 is connected to the movable rod 502 through a gear and rack structure, when the first handle 504 drives the transmission rod 503 to rotate, the movable rod 502 can move. Then, the pressure block 505 and the pressure sensor 506 come into contact with the test tube 404 or the connecting arm 407 and provide pressure. Then, the strain gauge 507 can detect the changes in the test tube 404.

[0043] refer to Figure 3 The moving component 402 includes a sliding groove 4021, a connecting plate 4022, and a cylinder 4023. The sliding groove 4021 is formed on the cross arm 3, and the connecting plate 4022 is fixedly mounted on the mounting base 401. The connecting plate 4022 is slidably connected in the sliding groove 4021. The cross-sections of the connecting plate 4022 and the sliding groove 4021 are both convex. The cylinder 4023 is fixedly mounted at one end of the cross arm 3, and the telescopic shaft of the cylinder 4023 is slidably connected to the connecting plate 4022. By setting the sliding groove 4021, the connecting plate 4022, and the cylinder 4023, in use, the connecting plate 4022 is connected to the mounting base 401, and then the cylinder 4023 can drive the connecting plate 4022 to move in the sliding groove 4021, thereby enabling the mounting base 401 to drive the round tube 404 to be measured to move.

[0044] refer to Figure 1 A fixed plate 6 is fixedly installed at one end of the slide table 14. A lead screw 7 is rotatably connected to the support arm 2. The lead screw 7 passes through the movable seat 501 and the fixed plate 6. The lead screw 7 is threadedly rotatably connected to the movable seat 501. A second handle 8 is fixedly installed at one end of the lead screw 7. By setting the fixed plate 6, the lead screw 7 and the second handle 8, when in use, the fixed plate 6 first cooperates with the support arm 2 to enable the lead screw 7 to be installed and rotated. Since the lead screw 7 is threadedly rotatably connected to the movable seat 501, when the lead screw 7 rotates, it can drive the movable seat 501 to move, and then the pressure block 505 can be moved to a suitable position according to the length of the round tube 404 to be measured.

[0045] refer to Figure 4 A mounting block 9 is provided on the cross arm 3. A through groove 10 is provided in the mounting block 9. The beam to be tested 11 is provided inside the through groove 10. The beam to be tested 11 is detachably installed in the through groove 10 by bolts. Strain gauges 507 are wound on the surface of the beam to be tested 11. By setting up the mounting block 9, the through groove 10 and the beam to be tested 11, when it is necessary to perform a bending test on the beam to be tested 11, the beam to be tested 11 is first fixed in the through groove 10 of the mounting block 9, and then the moving seat 501 is moved to the bottom of the beam to be tested 11. Then, the bending test on the beam to be tested 11 is performed by the pressure block 505 and the sensor.

[0046] refer to Figure 1 The slide table 14 has a scale line 12. By setting the scale line 12, when in use, the length of the round tube 404 to be measured is compared with the scale line 12, which makes it easier to move the moving seat 501 to the corresponding area.

[0047] refer to Figure 1 and Figure 6 Below the moving rod 502, there is a metal beam bending test mechanism 13 and a compressive strength measurement mechanism 15. The metal beam bending test mechanism 13 and the compressive strength measurement mechanism 15 are respectively set with the pressure mechanism 5. The pressure mechanism 5 can provide downward pressure to the metal beam bending test mechanism 13 and the compressive strength measurement mechanism 15 through the pressure block 505 at the lower end of the moving rod 502.

[0048] By setting up the metal beam bending test mechanism 13 and the compressive strength measurement mechanism 15, the metal beam can be subjected to bending tests and compressive strength measurement tests during use, thus improving the multi-functionality of the equipment. When performing a compressive strength measurement test, the pressure block 505 is removed, the clamping plate 1503 required for the compressive strength measurement test is installed, the moving seat 501 is moved above the object to be tested 1502, and the object to be tested 1502 is fixed by the clamping plate 1503, and the compressive strength measurement test can be performed. (The metal beam bending test mechanism 13 is a direct application of the prior art, and its principle can be referred to, but is not limited to, the patent document with application number 2025206049477. The compressive strength measurement mechanism 15 is a direct application of the prior art, and its principle can be referred to, but is not limited to, the patent document with publication number CN109283052B.)

[0049] refer to Figure 2 The moving rod 502 and the transmitting rod 503 are both set to not contact the lead screw 7. By setting the relationship between the moving rod 502 and the transmitting rod 503 and the lead screw 7, the moving rod 502 and the transmitting rod 503 are set to not contact the lead screw 7, so as to avoid mutual interference when they are working.

[0050] Brief description of usage:

[0051] In use, the base 1 first installs and fixes the support arm 2, and the support arm 2 installs and fixes the cross arm 3. The mounting hole 403 on the base allows the test tube 404 to be installed. Then, the limiting rod 406 is inserted into the limiting hole 405. Through the compression of the limiting rod 406, the test tube 404 is fixed in the mounting hole 403. Then, when the moving component 402 moves the test tube 404 to the top of the pressure block 505, a bending test can be performed. When the moving component 402 causes the test tube 404 to be misaligned with the pressure block 505, the pressure block 505 transmits the force to the test tube 404 through the connecting arm 407. At this time, a torsional shear stress test of the test tube 404 can be performed.

[0052] Then, the movable base 501 can install the movable rod 502 and the transmission rod 503. Since the transmission rod 503 and the movable rod 502 are connected by a gear and rack structure, when the first handle 504 drives the transmission rod 503 to rotate, the movable rod 502 can move, and then the pressure block 505 and the pressure sensor 506 can contact the test tube 404 or the connecting arm 407 and provide pressure. Then the strain gauge 507 can detect the change in the test tube 404. The movable component 402 includes a sliding groove 4021, a connecting plate 4022 and a cylinder 4023. The connecting plate 4022 is connected to the mounting base 401. Then the cylinder 4023 can drive the connecting plate 4022 to move in the sliding groove 4021, thereby enabling the mounting base 401 to drive the test tube 404 to move.

[0053] Finally, the fixing plate 6 cooperates with the support arm 2 to enable the screw 7 to rotate. Since the screw 7 is threadedly connected to the moving seat 501, when the screw 7 rotates, it can drive the moving seat 501 to move. Then, according to the length of the test tube 404, the pressure block 505 can be moved to a suitable position. When it is necessary to perform a bending test on the test beam 11, first fix the test beam 11 in the through groove 10 of the mounting block 9, then move the moving seat 501 to the bottom of the test beam 11, and then perform a bending test on the test beam 11 through the pressure block 505 and the sensor.
