Description

Technical Field

[0001] The utility model relates to the technical field of Timken testing machines, and specifically relates to a Timken testing machine. Background Technique

[0002] The Timken ring-block (automatic) testing machine is mainly used to test the load-bearing capacity, friction characteristics, OK value, and scratch value of various lubricating oils and greases under sliding friction conditions to determine the extreme pressure performance of lubricating oils; it can also be used to test the wear resistance of various metal materials and non-metal materials (nylon, plastics, etc.) under sliding friction conditions; at the same time, it can also measure the frictional force of various materials and calculate the friction coefficient of various materials.

[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:

[0004] (1) During the detection of lubricating oil, it is necessary to adhere the lubricating oil to the surface of the test ring. Therefore, a receiving groove is required, which is located at the bottom end of the test ring to prevent the lubricating oil from falling and contaminating other components of the device. When in use, the height of the receiving groove cannot be adjusted, and at the same time, the detected object that has fallen into the receiving groove cannot be re-adhered to the surface of the test ring. In actual application, in addition to lubrication, oxidation reactions will also occur, and additives will be consumed and degraded during long-term use, affecting the test effect on the detected object;

[0005] (2) After the detected object falls into the receiving groove, it is necessary to clean the receiving groove. The existing receiving groove is fixedly installed on the device, and it is very inconvenient to disassemble it. Content of the Utility Model

[0006] In view of the deficiencies of the prior art, the utility model provides a Timken testing machine, which has the advantages of being able to adjust the height of the receiving groove and being convenient for quickly disassembling and assembling the receiving groove, and solves the problems raised in the background technique.

[0007] The utility model provides the following technical solution: a Timken testing machine, including a box body, the top of the box body is fixedly connected with an operation screen, one side of the operation screen is provided with a test host, the bottom end of the test host is fixedly connected with the top of the box body, the top of the test host is fixedly connected with a grease storage tank, one end of the output shaft of the test host is fixedly connected with a test ring, a grease receiving tank is arranged directly below the test ring, a base is arranged at the bottom end of the grease receiving tank, and telescopic rods are fixedly connected to the four corners of the bottom end of the base, and the bottom ends of the telescopic rods are fixedly connected with the upper surface of the box body.

[0008] Preferably, a spring is movably sleeved on the surface of the telescopic rod, the bottom end of the spring abuts against the top of the box body, and the top end of the spring abuts against the lower surface of the base.

[0009] Preferably, a bottom block is fixedly connected to the top end of the box body. Both ends of the bottom block are rotatably connected to a first bracket. The top end of the first bracket is rotatably connected to a sleeve block. The top end of the sleeve block is rotatably connected to a second bracket. The top end of the second bracket is fixedly connected to the bottom end of the base.

[0010] Preferably, a bidirectional threaded rod is threadedly connected to the inside of the sleeve block. One end of the bidirectional threaded rod is fixedly connected to a rotating rod.

[0011] Preferably, a sliding groove is formed on the upper surface of the base. The bottom end of the oil receiving tank is fixedly connected to a sliding block. The model specifications of the sliding block and the sliding groove match. Tightening bolts are threadedly connected to both ends of the base. The end of the tightening bolt abuts against the side surface of the sliding block.

[0012] Preferably, a motor is fixedly connected to the side surface of the oil receiving tank. The output shaft of the motor is fixedly connected to a stirring blade. The stirring blade is located inside the oil receiving tank.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. By providing a rotating rod, when a person rotates the rotating rod, the bidirectional threaded rod will be driven to rotate synchronously. While the bidirectional threaded rod rotates, the two sleeve blocks on the surface of the bidirectional threaded rod move in opposite directions, so that the included angle between the top block and the second bracket changes, thereby controlling the height of the base to be adjusted. And the elastic force of the spring is always applied to the base to support the four corners of the base, ensuring the stability of the base during the up and down movement. When the oil receiving tank moves to the bottom of the test ring, during the test process, the motor will drive the stirring blade to rotate inside the oil receiving tank, thereby stirring the test substance in the oil receiving tank, accelerating the contact and mixing of the test substance with the air, and making the experimental results more in line with the actual situation.

[0015] 2. When it is necessary to clean the test substance inside the oil receiving tank, the oil receiving tank needs to be disassembled and washed. At this time, when a person loosens the tightening bolt, the end of the tightening bolt moves away from the side surface of the sliding block, thereby reducing the friction force between the sleeve block and the side surface of the sliding block, facilitating the sliding of the sliding block out of the inside of the sliding groove, and thus realizing the rapid disassembly of the oil receiving tank. The operation is simple and fast, facilitating the cleaning of the test substance inside the oil receiving tank. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Among them, a spring 7 is movably sleeved on the surface of the telescopic rod 6, the bottom end of the spring 7 abuts against the top end of the box body 1, and the top end of the spring 7 abuts against the lower surface of the base 8. The elastic force of the spring 7 is always applied to the base 8 to support the four corners of the base 8, ensuring the stability of the base 8 during the up and down movement.

[0023] Among them, a bottom block 10 is fixedly connected to the top end of the box body 1, bracket ones 11 are rotatably connected to both ends of the bottom block 10, the top ends of the bracket ones 11 are rotatably connected to a sleeve block 12, the top end of the sleeve block 12 is rotatably connected to a bracket two 13, the top end of the bracket two 13 is fixedly connected to the bottom end of the base 8, a bidirectional threaded rod 15 is threadedly connected inside the sleeve block 12, one end of the bidirectional threaded rod 15 is fixedly connected with a rotating rod 16. When the rotating rod 16 is rotated, the bidirectional threaded rod 15 will be driven to rotate synchronously. While the bidirectional threaded rod 15 is rotating, the two sleeve blocks 12 on the surface of the bidirectional threaded rod 15 move in opposite directions, so that the included angle between the top block 14 and the bracket two 13 is changed, thereby controlling the height of the base 8 to be adjusted.

[0024] Among them, a chute 9 is provided on the upper surface of the base 8, and a slider 17 is fixedly connected to the bottom end of the oil receiving tank 18. The model specifications of the slider 17 and the chute 9 match. Tightening bolts 21 are threadedly connected to both ends of the base 8, and the end of the tightening bolt 21 abuts against the side surface of the slider 17. When disassembling and cleaning the oil receiving tank 18, at this time, after manually loosening the tightening bolt 21, the end of the tightening bolt 21 is moved away from the side surface of the slider 17, thereby reducing the friction between the sleeve block 12 and the side surface of the slider 17, facilitating the sliding of the slider 17 out of the inside of the chute 9, and thus the rapid disassembly of the oil receiving tank 18 can be realized.

[0025] Among them, a motor 20 is fixedly connected to the side surface of the oil receiving tank 18, and a stirring blade 19 is fixedly connected to the output shaft of the motor 20. The stirring blade 19 is located inside the oil receiving tank 18. The motor 20 will drive the stirring blade 19 to rotate inside the oil receiving tank 18, thereby stirring the test substance in the oil receiving tank 18 and accelerating the contact and mixing of the test substance with the air.

[0026] Working principle: When the device is in use, when a person rotates the rotating rod 16, the bidirectional threaded rod 15 will be driven to rotate synchronously. While the bidirectional threaded rod 15 is rotating, the two sleeve blocks 12 on the surface of the bidirectional threaded rod 15 move in opposite directions, thereby changing the angle between the top block 14 and the support two 13, thereby controlling the height of the base 8 to be adjusted. And the elastic force of the spring 7 is always applied to the base 8 to support the four corners of the base 8, ensuring the stability of the base 8 during the up and down movement. When the oil receiving tank 18 moves to the bottom end of the test ring 5, during the test process, the motor 20 will drive the stirring blade 19 to rotate inside the oil receiving tank 18, thereby stirring the test substance in the oil receiving tank 18 and accelerating the contact and mixing of the test substance with the air. When disassembling and cleaning the oil receiving tank 18, at this time, after manually loosening the tightening bolt 21, the end of the tightening bolt 21 is moved away from the side surface of the slider 17, thereby reducing the friction between the sleeve block 12 and the side surface of the slider 17, facilitating the sliding of the slider 17 out of the inside of the chute 9, and thus the rapid disassembly of the oil receiving tank 18 can be realized.
