Description

Technical Field

[0001] This utility model relates to the field of mechanical component performance testing technology, specifically a guide rail slider life testing machine in a dusty environment. Background Technology

[0002] As the core moving component of linear guide pairs, the guide slider is widely used in various mechanical equipment, and its service life directly determines the overall machine's operational stability and maintenance costs.

[0003] A published Chinese patent, publication number CN118549099A, discloses a guide rail slider life testing machine, which includes a test environment simulation chamber. The test platform and its test rail mounting plate, drive module and pressure module are all located inside the test environment simulation chamber. The temperature, humidity and contaminant concentration of the internal environment of the test environment simulation chamber can be adjusted.

[0004] Although the guide rail slider life testing machine provided by this patent is equipped with a test environment simulation chamber to simulate a dusty environment, the number of test stations is limited due to the overall structural design. The dust distribution is uneven and the dust utilization rate is low, which not only increases the consumption of dust materials during the test process, but also extends the life detection cycle of the guide rail slider and increases the test cost.

[0005] Therefore, it is necessary to design a dust environment guide rail slider life testing machine that can simultaneously test the life of multiple linear guide rail pairs in a dust environment. Utility Model Content

[0006] The purpose of this invention is to provide a guide rail slider life testing machine in a dusty environment to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a guide rail slider life testing machine in a dusty environment, including a test platform, a test box on the test platform, support seats fixed on both sides inside the test box, a bearing component fixed between the two support seats, and several sets of linear guide rail pairs symmetrically fixed on both sides of the bearing component. One side of the support base is provided with a first drive component, and the other side of the support base is provided with a second drive component. The output end of the first drive component is connected to several sets of eccentric reciprocating components, and the output end of the second drive component is connected to a powder turning roller. The eccentric reciprocating assembly includes an eccentric cam, a drive shaft is provided on one side of the eccentric cam, a pin is provided between the two eccentric cams, a plurality of pin wheels are sleeved on the pin, a connecting rod is fixed on the pin wheel, and the other end of the connecting rod is connected to the slider pin of the linear guide pair.

[0008] In one embodiment of the present invention, the bearing assembly includes a bearing shaft, the bearing shaft is fixed on two side support seats, one end of the bearing shaft is fixed inside the powder turning roller, a bearing bottom plate is fixed between the two bearing side plates, and the powder turning roller is rotatably sleeved on the two bearing shafts.

[0009] In one embodiment of the present invention, the first drive assembly includes a first servo motor and a first motor mount. The first servo motor is fixed to one side of the test bench via the first motor mount. The output end of the first servo motor is connected to a coupling. The other end of the coupling is connected to a rotating shaft. The other end of the rotating shaft passes through a bearing shaft and is connected to a transmission shaft near the side of the first drive assembly. Bearings are sleeved at both ends of the rotating shaft.

[0010] In one embodiment of the present invention, the second drive component includes a second servo motor and a second motor mount. The second servo motor is fixed to the side away from the first drive component via the second motor mount. The output end of the second servo motor is provided with a drive wheel. The powder turning roller is provided with a driven wheel. A transmission belt meshes between the drive wheel and the driven wheel. A bearing is sleeved on the transmission shaft near the second drive component and the bearing is located inside the bearing side plate.

[0011] In one embodiment of this utility model, the supporting base plate has a hollow structure.

[0012] In one embodiment of this utility model, the powder-turning roller has a transparent body, a powder-adding port is provided on one side of the powder-adding roller, and a transparent plate is detachably connected to the powder-adding port.

[0013] In one embodiment of the present invention, the test box is provided with openable transparent door panels on all four sides, and a control unit is installed on one side of the test box.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) By setting multiple sets of eccentric reciprocating components and the first drive component, life tests can be performed on multiple sets of linear guide pairs at the same time. The first servo motor drives the rotating shaft to rotate the eccentric cam, and then drives the slider to reciprocate along the linear guide through the pin and connecting rod. The design of multiple sets of pin wheels and connecting rods can drive multiple sets of sliders simultaneously, improve test efficiency, and the servo motor drive has high precision, which can accurately control the movement speed and stroke of the slider to meet the requirements of different test conditions. (2) By setting up a dust-turning roller and a second drive component, the dust can be evenly distributed in the test environment. The second servo motor drives the dust-turning roller to rotate through the drive wheel and transmission belt, which can continuously turn the dust in the box. With the hollow structure of the bearing base plate, the dust can be evenly covered on the surface of the linear guide rail pair, which truly simulates the operating environment of the guide rail slider under actual dust conditions, improves the authenticity and reliability of the test results, and improves the dust utilization rate.

[0022] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] This utility model provides a technical solution: a guide rail slider life testing machine under dusty conditions, including a test bench 10, a test chamber 11 on the test bench 10, support seats 20 fixed on both sides of the test chamber 11 inside the test bench 10, a bearing component 30 fixed between the two support seats 20, and several sets of linear guide rail pairs 40 symmetrically fixed on both sides of the bearing component 30; the test chamber 11 provides a relatively enclosed space for the testing process, which is convenient for creating a dusty testing environment. The support seats 20 provide stable support for the bearing component 30, ensuring the structural stability of the bearing component 30 during the testing process. The bearing component 30 can simultaneously install multiple sets of guide rail sliders to be tested, laying a structural foundation for the subsequent synchronous testing of multiple sets of linear guide rail pairs 40. One side of the support base 20 is equipped with a first drive component 50, and the other side of the support base 20 is equipped with a second drive component 60. The output end of the first drive component 50 is connected to several sets of eccentric reciprocating components 70, and the output end of the second drive component 60 is connected to a powder-turning roller 80. The first drive component 50 can provide stable power to the eccentric reciprocating components 70, causing the eccentric reciprocating components 70 to convert the rotational motion into linear reciprocating motion, thereby driving the slider on the linear guide rail pair 40 to perform reciprocating sliding in a simulated actual working condition, providing motion conditions for life testing. The second drive component 60 can drive the powder-turning roller 80 to rotate, continuously turning the dust in the test chamber 11, avoiding dust settling and causing uneven dust coverage on the surface of the guide rail slider, and ensuring the authenticity and consistency of the test environment. The eccentric reciprocating assembly 70 includes an eccentric cam 71, a drive shaft 72 on one side of the eccentric cam 71, and a pin 73 between the two eccentric cams 71. Several pin wheels 74 are sleeved on the pin 73, and a connecting rod 75 is fixed on the pin wheel 74. The other end of the connecting rod 75 is connected to the slider pin of the linear guide pair 40. The drive shaft 72 receives the rotational motion output by the first drive assembly 50 and drives the eccentric cam 71 to rotate. The rotation of the eccentric cam 71 drives the pin 73 and one end of the connecting rod 75 to perform eccentric rotational motion, thereby driving the slider of the linear guide pair 40 to perform linear reciprocating motion along the guide rail. The design of multiple sets of pin wheels 74 and connecting rods 75 can drive multiple sets of sliders simultaneously, which improves the testing efficiency while ensuring motion accuracy.

[0024] The bearing assembly 30 includes a bearing shaft 31, which is fixed on two side support seats 20. One end of the bearing shaft 31 is fixed inside the powder turning roller 80, and a bearing side plate 32 is fixed between the two side support plates 32. The powder turning roller 80 is rotatably sleeved on the two side bearing shafts 31. The bearing shaft 31 is fixed by the two side support seats 20, providing a reliable support frame for the entire bearing assembly 30. The frame structure formed by the bearing side plate 32 and the bearing bottom plate 33 can stably install the linear guide rail pair 40, ensuring the fixation of the guide rail position during the test. The powder turning roller 80 is rotatably sleeved on the bearing shaft 31, so that when the second drive assembly 60 drives the powder turning roller 80 to rotate, the bearing assembly 30 remains stationary. This achieves the dust turning function without affecting the test state of the guide rail slider, ensuring the stability and reliability of the test process.

[0025] The first drive assembly 50 includes a first servo motor 51 and a first motor mount 52. The first servo motor 51 is fixed to one side of the test bench 10 via the first motor mount 52. The output end of the first servo motor 51 is connected to a coupling 53, and the other end of the coupling 53 is connected to a rotating shaft 54. The other end of the rotating shaft 54 ​​passes through the bearing shaft 31 and is connected to the transmission shaft 72 near the side of the first drive assembly 50. Bearings are sleeved at both ends of the rotating shaft 54. The first motor mount 52 provides a stable installation for the first servo motor 51, preventing the vibration generated by the first servo motor 51 during operation from affecting the overall stability of the equipment. The coupling 53 can compensate for the installation error between the output shaft of the first servo motor 51 and the rotating shaft 54, reducing the impact and vibration during power transmission. The rotating shaft 54 ​​can rotate smoothly under the support of the bearings at both ends, efficiently transmitting the power of the first servo motor 51 to the transmission shaft 72, thereby driving the eccentric reciprocating assembly 70 to operate. The second drive assembly 60 includes a second servo motor 61 and a second motor mount 62. The second servo motor 61 is fixed to the side away from the first drive assembly 50 via the second motor mount 62. The output end of the second servo motor 61 is provided with a drive wheel 63, and the powder turning roller 80 is provided with a driven wheel 64. A transmission belt 65 is meshed between the drive wheel 63 and the driven wheel 64. The transmission shaft 72 near the second drive assembly 60 is fitted with a bearing, which is located inside the bearing side plate 32. The second motor mount 62 provides stable support for the second servo motor 61. The drive wheel 63, the driven wheel 64, and the transmission belt 65 cooperate to form a belt drive structure, which can smoothly transmit the rotational power of the second servo motor 61 to the powder turning roller 80. The bearing of the transmission shaft 72 near the second drive assembly 60 is located inside the bearing side plate 32, which not only ensures the smooth rotation of the transmission shaft 72, but also ensures that the power transmission of the second drive assembly 60 and the eccentric reciprocating assembly 70 do not interfere with each other and operate independently, thus ensuring the synchronous and stable testing of dust turning and slider movement.

[0026] The supporting base plate 33 has a hollow structure; the hollow structure allows dust to pass smoothly through the supporting base plate 33, preventing dust accumulation on the supporting base plate 33, while also reducing the overall weight of the supporting component 30 and reducing the operating load of the equipment. The powder turning roller 80 has a transparent cylinder body, and a powder filling port 81 is opened on one side of the powder turning roller 80, and a transparent plate 82 is detachably connected to the powder filling port 81; the transparent cylinder body allows the operator to observe the operation of the equipment from any angle outside the roller. The powder filling port 81 provides a dedicated channel for dust filling before testing and possible dust replenishment during testing. The detachable transparent plate 82, while sealing the powder filling port 81 to prevent dust leakage, forms a unified transparent observation system with the transparent cylinder body, ensuring that the entire dust turning process and the reciprocating motion of the linear guide pair 40 are under observation. The test chamber 11 has four openable transparent doors 111 on all four sides, and a control unit 112 is installed on one side of the test chamber 11. The four openable transparent doors 111 allow operators to clearly observe the running status of the linear guide pair 40, the dust distribution, and the working status of the powder turning roller 80 inside the test chamber 11 from different angles. The openable design facilitates the installation and debugging of the equipment, sample loading and unloading, and cleaning and maintenance after testing. The control unit 112 installed on one side of the test chamber 11 integrates the control functions of the equipment. Operators can use the control unit 112 to accurately set parameters such as the speed of the first servo motor 51 and the second servo motor 61, and the test duration, and monitor the equipment operation data in real time, realizing comprehensive visual monitoring and convenient operation control of the testing process.

[0027] Working principle: Before testing, open the transparent plate 82 of the powder turning roller 80, and load the preset amount of powder into the powder turning roller 80 through the powder filling port 81, and then install the transparent plate 82. Subsequently, the first servo motor 51 outputs rotational power, which is transmitted to the rotating shaft 54 ​​via the coupling 53. The rotating shaft 54 ​​then transmits the power to the transmission shaft 72 connected to it. The transmission shaft 72 drives several eccentric cams 71 to rotate simultaneously. The eccentric structure of the eccentric cams 71 causes the pin shaft 73 to rotate eccentrically, which in turn drives the slider of the linear guide pair 40 to reciprocate linearly along the guide rail through the pin wheel 74 and the connecting rod 75, thereby realizing the motion simulation of the life test. Meanwhile, after the second servo motor 61 starts, the drive wheel 63 at its output end drives the driven wheel 64 on the powder turning drum 80 to rotate through the transmission belt 65, so that the powder turning drum 80 rotates around the bearing shaft 31. During the rotation of the powder turning drum 80, the internal dust is continuously turned over to simulate the real dust working environment.
