Description

Technical Field

[0001] This utility model relates to the field of guide rail testing technology, and in particular to a guide rail wear resistance testing device. Background Technology

[0002] Currently, guide rails are common transmission and positioning components in industrial automation and precision equipment. Their wear resistance directly affects the operating accuracy and service life of the equipment. Most existing guide rail wear resistance testing devices adopt a fixed structure. The drive device drives the grinding component to contact and rub against the guide rail surface to simulate the wear during use, thereby evaluating the wear resistance of the guide rail material. These testing devices are usually equipped with motor drive, sliding rail and friction components. They are suitable for comparing and initially screening the wear resistance of standard guide rails and are widely used in materials laboratories and quality testing sites.

[0003] However, guide rails made of different materials have significant differences in hardness, surface treatment processes, and application environments. Consequently, the friction force required for wear resistance testing also varies considerably. Most existing guide rail wear resistance testing devices adopt a fixed pressure structure and lack the function of finely adjusting the friction force. This makes it difficult to flexibly adapt to the characteristics of specific test materials, resulting in uncontrollable friction force or deviation from actual working conditions during the testing process. Consequently, the accuracy and reference value of the test results are affected, limiting the applicability of such devices in the testing of diverse guide rail materials. Utility Model Content

It can precisely adjust the pressure applied by the grinding head to the guide rail surface, adapting to the wear resistance testing requirements of guide rails of different materials.

A drive belt passes through a limiting sleeve plate, which is installed on both sides of the top of the testing platform to ensure the stability and controllability of the drive belt's running path. This device achieves adjustable control of friction pressure through the friction adjustment component, and combined with the adaptive clamping structure inside the housing, effectively solves the problem in existing technologies where friction cannot be adjusted according to the guide rail material, improving the accuracy, adaptability, and versatility of the testing process.

[0022] The guide rail wear resistance testing device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0023] like Figures 1-4As shown, the guide rail wear resistance testing device of this utility model embodiment may include an operating table 1, a testing platform 2 symmetrically fixedly connected to the top of the operating table 1, a placement housing 3 slidably mounted on the top of the testing platform 2, and placement platforms 4 symmetrically fixedly connected to the top of the operating table 1 relative to the two sides of the testing platform 2. A driving assembly 5 is installed on the placement platform 4. The driving assembly 5 is connected to a driving belt 6 to drive the placement housing 3 to slide on the top of the testing platform 2. A support frame 7 is fixedly connected to the middle section of the top of the operating table 1. A friction adjustment component 8 is installed on the support frame 7, and the end of the friction adjustment component 8 is located above the placement housing 3.

[0024] It should be noted that the embodiment described includes an operating platform 1, which adopts an integral steel frame structure with good rigidity and load-bearing capacity, used to support the overall testing mechanism and provide a stable working platform. A testing platform 2 is symmetrically fixedly connected to the top of the operating platform 1. The testing platform 2 is a long, narrow track structure with high-strength, wear-resistant guide rails on its upper surface to facilitate smooth sliding of the housing 3. The housing 3 is slidably mounted on the top of the testing platform 2. The housing 3 adopts an integral molding structure and has an internal clamping mechanism for fixing the guide rail specimen, facilitating quick placement and stable positioning of the tested guide rail. Placement platforms 4 are symmetrically fixedly connected to the top of the operating platform 1 relative to the two sides of the testing platform 2. A drive assembly 5 is installed on the placement platform 4, which includes a motor drive module, a guide wheel 51 system, and... The tensioning device ensures synchronization and stability during the driving process. The driving component 5 is connected to the driving belt 6, which drives the housing 3 to achieve stable reciprocating sliding motion on the top of the testing platform 2. The driving belt 6 is made of flexible and wear-resistant material, which has strong tensile strength and life guarantee. A support frame 7 is fixedly connected to the top center of the operating table 1. The support frame 7 adopts a frame structure and a friction adjustment component 8 is installed on the support frame 7. The friction adjustment component 8 is a longitudinally arranged downward pressing structure. It adjusts the downward pressure by means of a precision lead screw or electric push rod. The end of the friction adjustment component 8 is located above the housing 3. It can adjust the applied friction force according to the testing requirements of different material guide rails, thereby accurately controlling the grinding intensity, making the testing process more in line with actual working conditions, and improving the representativeness and reliability of the testing results.

[0025] Specifically, the operating platform 1 serves as the overall support structure, providing a stable testing foundation. The testing platform 2 is located on top of the operating platform 1, and a slidingly mounted placement housing 3 is used to hold the guide rail to be tested. The drive assembly 5 is installed on the placement platforms 4 on both sides of the operating platform 1, and is connected to the placement housing 3 via a drive belt 6. Driven by the first drive device 53, the placement housing 3 moves back and forth on the testing platform 2, simulating the working state of the guide rail in actual use. The support frame 7 is located in the middle of the operating platform 1, and the friction adjustment component 8 installed on it controls the up and down movement of the grinding head 84 through the second drive device 81, causing the grinding head 84 to contact the guide rail surface and generate friction, thereby conducting a wear resistance test on the guide rail. At the same time, the friction force can be controlled by adjusting the downward pressure of the friction adjustment component 8 to adapt to the testing requirements of guide rails of different materials. This structure achieves precise control of the grinding contact pressure through the friction adjustment component 8, solving the problem of not being able to adjust the friction force according to different guide rail materials, thereby improving the adaptability and scientific nature of wear resistance testing, and enhancing the representativeness and accuracy of the test results.

[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, the drive assembly 5 includes a guide wheel 51, a support rod 52, a first drive device 53, and a drive arm 54. One end of the drive belt 6 is fixedly connected to one end of the placement housing 3, and the other end of the drive belt 6 passes around the bottom of the placement housing 3 and is fixedly connected to the other end of the drive belt 6. The drive belt 6 is fitted with two guide wheels 51. One end of the support rod 52 is fixedly connected to one side of the inner wall of one of the placement platforms 4, and the other end of the support rod 52 passes through one of the guide wheels 51 and is fixedly connected to the other side of the inner wall of the placement platform 4. One of the guide wheels 51 is rotatably connected to the support rod 52. The first drive device 53 is mounted on the other placement platform 4. One end of the drive arm 54 is fixedly connected to the output end of the first drive device 53, and the other end of the drive arm 54 is fixedly passed through the other guide wheel 51 and is rotatably connected to the inner wall of the placement platform 4.

[0027] It should be noted that the first driving device 53 described in this embodiment is a drive motor. One end of the drive belt 6 is fixedly connected to one side of the housing 3 for transmitting power, and the other end goes around the bottom of the housing 3 and returns, and is fixedly connected to the other end of the drive belt 6, forming a closed ring structure to ensure transmission continuity. Two guide wheels 51 are sleeved on the outside of the drive belt 6, located at both ends of the movement path of the housing 3, to guide the drive belt 6 to run smoothly within a defined track and prevent the drive belt 6 from deviating or slipping during operation. The support rod 52 is used to install and fix the guide wheels 51. One end of the support rod is fixedly connected to one side of the inner wall of one of the placement platforms 4, and the other end passes through one of the guide wheels 51 and extends to the placement platform 4. The guide wheel 51 is fixedly connected to the other side of the inner wall, enabling it to rotate stably and maintain a straight drive path, thus improving the mechanical stability and guiding accuracy of the entire structure. One guide wheel 51 is rotatably connected to the support rod 52, ensuring that the drive belt 6 can slide freely on it. The first drive device 53 is a motor structure, installed on the other side of the placement platform 4, used to provide the driving force required for reciprocating motion. Its output end is fixedly connected to one end of the drive arm 54, and the other end of the drive arm 54 is fixedly passed through the center of another guide wheel 51 and rotatably connected to the inner wall of the placement platform 4 through a bearing structure, so that the motor output torque can smoothly drive the guide wheel 51 to rotate, thereby driving the drive belt 6 to circulate, realizing the smooth sliding of the placement shell 3 along the surface of the detection platform 2. The overall structure of this drive assembly 5 is compact, the transmission path is clear, and the operation is stable and reliable, which can effectively improve the reciprocating motion efficiency and simulation accuracy in the guide rail wear resistance testing process.

[0028] Specifically, after the drive device is started, the drive arm 54 drives the guide wheel 51 to rotate, thereby causing the drive belt 6 to generate continuous cyclic motion. This, in turn, drives the housing 3 to slide back and forth on the surface of the testing platform 2, so that the grinding path covers the entire area of ​​the guide rail to be tested. This structure, through the cooperation of the enclosed drive belt 6 and the guide wheel 51, not only improves the smoothness of the movement and the compactness of the structure, but also solves the problem of the guide rail wear resistance testing device having a single structure and being unable to achieve smooth reciprocating motion. It effectively enhances the ability to simulate uniform friction on the entire surface of the guide rail during the testing process, and improves the accuracy and applicability of the test.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, the friction adjusting component 8 includes a second driving device 81, a driving rod 82, a threaded head 83, and a grinding head 84. The second driving device 81 is mounted on the top of the support frame 7. The output end of the second driving device 81 passes through the top of the support frame 7 and is fixedly connected to one end of the driving rod 82. One end of the threaded head 83 is fixedly connected to the other end of the driving rod 82, and the grinding head 84 is threadedly connected to the other end of the threaded head 83.

[0030] It should be noted that the second drive device 81 described in this embodiment is a cylinder.

[0031] Specifically, the second drive device 81 is installed on the top of the support frame 7 to provide longitudinal driving capability. Its output end passes through the support frame 7 and is fixedly connected to the drive rod 82. After the second drive device 81 is activated, the drive rod 82 can move up and down vertically, thereby driving the threaded head 83 and the grinding head 84 below to rise and fall as a whole. The threaded head 83 is connected to the end of the drive rod 82 and has a threaded structure. The grinding head 84 is connected to the end of the threaded head 83 by a thread. The user can adjust the screw depth of the grinding head 84 according to different testing requirements to further fine-tune the contact force and pressure between the grinding head 84 and the guide rail surface, thereby forming a controllable friction force. During the testing process, the grinding head 84 contacts the guide rail surface and generates wear, simulating the friction state of the guide rail during use, and realizing the evaluation of wear resistance performance. This structure provides macroscopic position adjustment through the second drive device 81 and fine adjustment function through the threaded head 83, realizing a dual control method. It effectively solves the problem of not being able to adjust the friction force according to different guide rail materials, improves the accuracy, applicability and scientific nature of the test, and makes the guide rail wear resistance assessment more in line with actual working conditions.

[0032] Adjusting screws 31 are symmetrically threaded through both sides of the housing 3. Clamping plates 32 are symmetrically slidably engaged on the inner wall of the housing 3. One end of the adjusting screws 31 is rotatably connected to the outer wall of the clamping plates 32.

[0033] It should be noted that, in this embodiment, the inner wall of the housing 3 is symmetrically fitted with clamping plates 32. The clamping plates 32 are integrally injection molded or have a metal + rubber composite structure. They have guide ridges extending along the inner wall of the housing, which cooperate with guide grooves on the inner side of the housing to achieve stable sliding while restricting its degree of freedom, making the clamping action smoother. One end of the adjusting screw 31 has a hexagonal adjusting head or an anti-slip knob structure, facilitating manual operation or tool-assisted adjustment by the user. The side of the clamping plate 32 near the guide rail contact surface has a flexible anti-slip pad layer to protect the guide rail surface and prevent scratches or indentations caused by excessive clamping force. This structure allows for stepless adjustment according to the guide rail size, ensuring accurate, stable, and rapid clamping and positioning during the testing of guide rails of different specifications, further improving the efficiency and reliability of the entire testing process.

[0034] It should be understood that the top of the detection platform 2 is symmetrically fixedly connected to a limit sleeve, and the drive belt 6 passes through the interior of the limit sleeve.

[0035] In summary, the guide rail wear resistance testing device of this utility model uses the drive assembly 5 to drive the placement housing 3 to slide back and forth on the testing platform 2, causing the guide rail fixed inside the placement housing 3 to rub against the adjustable pressure grinding head 84 above, thereby simulating the wear condition of the guide rail during actual use. The friction force adjustment component 8 includes a second drive device 81, a drive rod 82, a threaded head 83, and a grinding head 84, which can precisely adjust the pressure applied by the grinding head 84 to the surface of the guide rail, adapting to the wear resistance testing requirements of guide rails of different materials. The adjusting screw 31 and the clamping plate 32 are structurally installed on both sides inside the placement housing 3 to achieve lateral clamping and stable positioning of guide rails of different specifications. The drive belt 6 passes through the limiting sleeve, which is installed on both sides of the top of the testing platform 2 to ensure the stability and controllability of the running path of the drive belt 6. This device achieves adjustable control of friction pressure through the friction force adjustment component 8, and combined with the adaptive clamping structure inside the placement housing 3, effectively solves the problem in the prior art that the friction force cannot be adjusted according to the guide rail material, improving the accuracy, adaptability, and versatility of the testing process.
