Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, in particular to an antimony-free friction-reducing material testing platform. Background Art

[0002] Anti-friction materials are mainly used to make various sliding bearings. These materials have the characteristics of low friction coefficient and good wear resistance, and can reduce the friction between the contact parts of friction parts in various machines. Antimony-free anti-friction materials are anti-friction materials that do not contain antimony elements. This is because the use of antimony materials will have a certain impact on the environment and human health.

[0003] Most of the current anti-friction material test platforms fix the anti-friction material workpiece (such as babbitt alloy, copper-based alloy, etc.) on the test bench and perform friction tests on it through friction components to detect the friction and wear properties of the material. However, the existing equipment is usually inconvenient to automatically turn over the anti-friction material workpiece. After testing one side of the workpiece, when the other side of the workpiece needs to be tested, the personnel need to operate the clamping component to release the fixation of the workpiece, and then turn the workpiece over and fix it again. The process is cumbersome and time-consuming, which easily increases the labor intensity of the personnel and the test time, resulting in reduced convenience of use and test efficiency.

At this time, the gear cannot rotate. When the lifting mechanism stops moving downward, the rack is reset and meshes with the gear.

At this time, the flip frame is flipped exactly one hundred and eighty degrees, so the effect of automatically turning over the workpiece is achieved. During the process, there is no need for personnel to turn over the workpiece, which reduces labor intensity and effectively improves convenience of use and test efficiency.

DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0030] See also Figure 1 - Figure 5 The utility model provides an antimony-free antifriction material test platform, comprising: a test bench 1 and two support blocks 2 symmetrically fixedly installed on the top of the test bench 1;

[0031] A rotating shaft rod 3 that penetrates through the surface of the supporting block 2 and is rotatably connected thereto;

[0032] A flip frame 4 fixedly connected between opposite ends of the rotating shaft rod 3;

[0033] A mounting plate 6 is arranged on the top of the test bench 1, and the mounting plate 6 is moved along the height direction of the test bench 1 by a lifting mechanism arranged on the test bench 1;

[0034] and a transmission mechanism disposed on the test bench 1 for driving the rotating shaft rod 3 to rotate when the mounting plate 6 rises;

[0035] The transmission mechanism includes a gear 5 fixedly connected to one end of a rotating shaft rod 3, and a rack 7 movably connected to the bottom of a mounting plate 6 through a rotating shaft 1 and a torsion spring 1 and meshing with the gear 5.

[0036] The transmission mechanism also includes a guide column 8 rotatably connected to one side of the rack 7, a channel steel shell 9 fixedly installed on one side of the test bench 1, and a guide block 10 movably connected to the top of the channel steel shell 9 through a second rotating shaft and a second torsion spring and cooperating with the guide column 8.

[0037] The technical solution provided by this embodiment is as follows: when in use, the lifting mechanism is moved downward for testing, and the mounting plate 6 and the rack 7 are driven downward synchronously. At this time, the guide column 8 is in contact with the guide block 10, and the inclined surface of the guide block 10 is used to guide the guide column 8, thereby driving the rack 7 to swing compared with the mounting plate 6 and causing the torsion spring to twist. At this time, the rack 7 is not in contact with the gear 5. When the lifting mechanism stops moving downward for testing, the guide column 8 moves to the bottom of the channel steel shell 9, and the rack 7 is reset by the torsion spring, so that the guide column 8 moves into the channel steel shell 9. At this time, the rack 7 is in contact with the gear 5. After the test on one side of the workpiece is completed, the lifting mechanism drives the mounting plate 6 moves up and resets, at this time the guide column 8 will move up in the channel steel shell 9, and at the same time the rack 7 moves up to drive the gear 5 and the rotating shaft rod 3 to rotate and make the flip frame 4 rotate, and the guide column 8 will contact with the bottom of the guide block 10 as the rack 7 moves, and drive the guide block 10 to rotate and swing to twist the torsion spring 2, so that the guide column 8 can be moved out of the channel steel shell 9, and after moving out, the guide block 10 is reset driven by the torsion spring 2, when the mounting plate 6 is reset, the rack 7 and the gear 5 are separated, and the flip frame 4 is flipped exactly 180 degrees at this time, so the effect of automatically turning over the workpiece is achieved, and there is no need for personnel to turn over the workpiece during the process, which reduces the labor intensity and effectively improves the convenience of use and the test efficiency.

[0038] Furthermore, the lifting mechanism includes an electric push rod 11 fixedly installed on one side of the top of the test bench 1, a movable plate 12 fixedly installed on the output end of the electric push rod 11, and a mounting plate 6 fixedly installed on one side of the movable plate 12.

[0039] Specifically, when in use, the electric push rod 11 can drive the movable plate 12 to rise and fall, so as to test the workpiece, and can also synchronously drive the mounting plate 6 to rise and fall, and drive the gear 5 and the rotating shaft rod 3 to rotate through the rack 7, so as to make the flip frame 4 flip.

[0040] Furthermore, a test mechanism is provided at the bottom of the movable plate 12;

[0041] The test mechanism includes a friction assembly 13 fixedly mounted on one end of the bottom of the movable plate 12, wherein the friction assembly 13 includes a power part and a friction part mounted on the output end of the power part. This part of the structure is prior art, and those skilled in the art can make a choice based on actual conditions, and will not be elaborated on here.

[0042] Specifically, the lifting mechanism can drive the friction assembly 13 to lift the friction assembly 13 so as to make the friction assembly 13 contact with the workpiece, thereby achieving the purpose of the test.

[0043] Furthermore, a clamping mechanism is provided in the flip frame 4;

[0044] The clamping mechanism includes a bidirectional screw 14 which is rotatably connected to one side of the flip frame 4 through a base block and two clamping plates 15 which are symmetrically threadedly connected to the surface of the bidirectional screw 14. A groove which slides with the clamping plate 15 is opened on one side of the flip frame 4, and rubber pads are fixedly installed on the opposite surfaces of the two clamping plates 15.

[0045] Specifically, by placing the workpiece in the flip frame 4, the bidirectional screw rod 14 is rotated to drive the two clamping plates 15 to slide in the groove, so that the two clamping plates 15 are close to each other to contact and clamp the workpiece, and under the action of the rubber pad, the friction between the clamping plates 15 and the workpiece can be enhanced, thereby achieving the effect of clamping and fixing the workpiece.

[0046] Furthermore, a supporting mechanism is provided on the top of the test bench 1;

[0047] The supporting mechanism includes an electric push rod 16 fixedly mounted on the top of the test bench 1 and located below the flip frame 4 , and a supporting block 17 fixedly connected to the output end of the electric push rod 16 .

[0048] Specifically, during the test, the workpiece can be placed on the supporting block 17, and then the supporting block 17 can be moved upward by the electric push rod 16 so that it is located in the flip frame 4, and the workpiece is fixed by the clamping mechanism. When the flip frame 4 is rotated, the electric push rod 16 drives the supporting block 17 to move downward to leave enough space for the rotation of the flip frame 4, and then drives the supporting block 17 to move upward again to support the workpiece, so as to ensure the stability of the test. Example

[0049] Based on Example 1, in this example: support screws 18 are fixedly installed at the four corners of the bottom of the test bench 1, a support screw barrel 19 is threadedly connected to the surface of the support screw 18, a foot plate 20 is fixedly installed at the bottom of the support screw barrel 19, and a rotating block is fixedly installed on the surface of the support screw barrel 19.

[0050] The technical solution provided in this embodiment is: when the test bench 1 encounters an uneven ground, the corresponding support screw barrel 19 is rotated to make it rise and fall along the surface of the support screw rod 18, thereby driving the foot plate 20 to move until the test bench 1 is leveled, thereby facilitating the adjustment of the test bench 1 and improving the flexibility of use.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
