Description

Technical Field

[0001] This invention relates to the field of linear guide pair testing technology, and in particular to a high-efficiency rolling linear guide pair performance testing device. Background Technology

[0002] High-efficiency rolling linear guide pairs are core transmission components in precision mechanical equipment. Their surface flatness directly affects the motion accuracy, load-bearing capacity, and service life of the equipment. Surface flatness testing of high-efficiency rolling linear guide pairs is a key step in the production and quality control of these pairs. Currently, a contact testing method is used, where a testing probe slides against the side of the high-efficiency rolling linear guide pair to detect surface flatness. The test data is transmitted in real time to a display screen on a controller on one side, allowing staff to visually view the flatness parameters and make testing judgments.

[0003] When testing the surface flatness of a high-efficiency rolling linear guide pair, the pair to be tested is fixed in the testing slot or placement slot of the testing platform, so that the testing probe contacts the surface of the high-efficiency rolling linear guide pair. Under the action of the moving component or the operator's push, the testing probe slides at a constant speed along a preset path on the side of the guide pair. During the sliding process, the probe senses the surface unevenness changes in real time, converts the mechanical displacement signal into an electrical signal, and after being processed by the data processing module, it is converted into an intuitive flatness value and curve. The flatness value is displayed on the screen, and the staff judges whether the surface flatness of the guide pair meets the standard based on the displayed data.

[0004] Currently, the testing process requires first inspecting one side of the guide rail pair. Then, staff must manually disassemble and adjust the installation direction of the guide rail pair before re-fixing it and inspecting the other side. The operation is cumbersome and time-consuming. However, the repeated adjustments increase the workload of staff and reduce overall testing efficiency, making it difficult to meet the testing needs of high-efficiency mass production.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be further described in detail below.

[0022] This invention provides a high-efficiency rolling linear guide performance testing device, including a testing platform 1. A moving component 2 is provided on the testing platform 1. The moving component 2 is used to drive the testing component to translate along the length direction of the guide pair to be tested in order to adapt to the continuous testing of multiple sets of guide pairs. A fixed rod 201 is fixedly connected to the upper surface of the testing platform 1. A first sliding groove 202 is provided inside the fixed rod 201. The inner surface of the first sliding groove 202 is slidably connected to a slider 203. A lead screw 204 is threadedly connected to the inner surface of the slider 203. A forward and reverse motor 205 is fixedly connected to the rear surface of the fixed rod 201. The output end of the forward and reverse motor 205 is fixedly connected to the lead screw 204.

[0023] Specifically, the testing platform 1 is the fundamental load-bearing component of the entire high-efficiency rolling linear guide pair performance testing device, providing rigid support for the stable operation of each component. The testing platform 1 is cast from high-strength cast iron and undergoes aging treatment to eliminate internal stress, ensuring structural stability under long-term load and vibration conditions, thus providing a fundamental guarantee for subsequent high-precision testing. The forward and reverse motors 205 are servo motors, featuring adjustable speed and precise positioning. Their control signals are output by the controller 23, allowing the movement speed and stopping position to be set according to the length of the guide pair and the testing accuracy requirements. Combined with the precision thread of the lead screw 204, the translation accuracy of the slider 203 reaches ±0.02mm. This precision ensures the positioning consistency during the testing of multiple guide pairs. The fixed rod 201, fixedly connected to the upper surface of the testing platform 1, provides an installation reference and guide carrier for the moving component 2. The first sliding groove 202 inside the fixed rod 201 forms a sliding fit with the slider 203, providing precise guidance for the translation of the slider 203. When driving is required... When the first probe adjustment assembly 10 and the second probe adjustment assembly 11 move, the forward and reverse motor 205, which is fixedly connected to the rear surface of the fixed rod 201, is energized and started. The output shaft of the forward and reverse motor 205 is connected to the lead screw 204 through a coupling, which accurately converts the rotational motion of the forward and reverse motor 205 into linear motion. The joint between the lead screw 204 and the slider 203 adopts a double-direction angular contact bearing to ensure the stability and accuracy of the slider 203 during the movement. The rotation of the output end of the forward and reverse motor 205 drives the lead screw 204 to rotate synchronously. Since the inner surface of the slider 203 is threadedly connected to the lead screw 204, the rotational motion of the lead screw 204 is converted into the linear motion of the slider 203 along the length direction of the first slide groove 202, which in turn drives the first probe adjustment assembly 10 and the second probe adjustment assembly 11 on the slider 203 to move. The first detection probe 1006 and the second detection probe 1106 on the first probe adjustment assembly 10 and the second probe adjustment assembly 11 move to realize the synchronous detection of multiple sets of guide rail pairs on the placement plate 16. The lead screw 204 is a high-precision ball screw 204, which ensures the positioning consistency during the inspection of multiple sets of guide rail pairs and avoids data distortion caused by positioning deviation. The moving component 2 drives the first probe adjustment component 10 and the second probe adjustment component 11 to move, which can simultaneously inspect the left and right sides of multiple sets of high-efficiency rolling linear guide rail pair inspection components 18, thereby improving the inspection efficiency of high-efficiency rolling linear guide rail pair inspection components 18 of the same size.

[0024] The moving component 2 includes a slider 203, and an electric telescopic rod 4 is fixedly connected to the upper surface of the slider 203 via a support block 3. The upper end of the electric telescopic rod 4 is fixedly connected to a first moving frame 5.

[0025] Specifically, the upper surface of the slider 203 is fixedly connected to the electric telescopic rod 4 via the support block 3. The support block 3 is made of alloy steel, and its upper and lower surfaces are doubly fixed to the slider 203 and the electric telescopic rod 4 by welding and bolts, ensuring connection strength and facilitating subsequent maintenance and replacement. The electric telescopic rod 4 is a height-adjustable structure. When it is necessary to detect different height positions of the guide rail pair, the telescopic end of the electric telescopic rod 4 drives the first movable frame 5, which is fixedly connected to it, to rise and fall synchronously, thereby adjusting the height of all detection components on the first movable frame 5, so that the first detection probe 1006 and the second detection probe 1106 can be accurately aligned with the height position to be detected on the guide rail pair. The first movable frame 5 provides a stable carrier for the installation of the upper guide support column 6 and support plate 7.

[0026] The upper surface of the first movable frame 5 is fixedly connected to a support plate 7 via a guide support column 6. A cylinder 8 is fixedly connected to the upper surface of the support plate 7. The output end of the cylinder 8 is fixedly connected to a first movable plate 9. A first probe adjustment assembly 10 and a second probe adjustment assembly 11 are provided on the first movable plate 9.

[0027] Specifically, the upper surface of the first movable frame 5 is fixedly connected to a support plate 7 via guide support columns 6. There are two guide support columns 6, which are distributed symmetrically on the left and right sides of the support plate 7 to form a stable support structure. The outer surface of the guide support columns 6 is ground to ensure a smooth finish, providing guidance for the sliding of the first movable plate 9. The support plate 7 is a rectangular steel plate, and its lower surface is fastened to the upper end of the guide support column 6 with bolts. The upper surface is used to fix and install the cylinder 8. The cylinder 8 serves as the synchronous drive power source for the first probe adjustment assembly 10 and the second probe adjustment assembly 11. When the guide rail pair to be tested needs to be tested, the cylinder 8 is activated to push the piston rod to extend, driving the first movable plate 9 to move downward along the axis of the guide support column 6. When the test is completed, the piston rod of the cylinder 8 is retracted, and the first movable plate 9 is synchronously reset. A flow control valve is installed at the inlet and outlet of cylinder 8, which can precisely adjust the extension and retraction speed of the piston rod, with an adjustment range of 10-100 mm / s. This ensures smooth contact and separation between the probe and the guide rail surface, avoiding damage to the probe or scratches on the guide rail surface caused by hard collisions. The aforementioned flow control valve is a mature existing technology in the field of pneumatic control. Its core structure and working principle have not been innovatively improved in this device. This invention only selects and integrates it based on the dynamic requirements of the probe-guide rail contact in the detection process. A first probe adjustment assembly 10 and a second probe adjustment assembly 11 are provided on the first moving plate 9. The two assemblies are symmetrically distributed on the front and rear sides of the first moving plate 9, corresponding to the left and right sides of the guide rail to be detected, respectively, to achieve synchronous detection.

[0028] The first probe adjustment assembly 10 includes a first fixed plate 1001, a first guide groove 1002 is provided inside the first fixed plate 1001, a first adjustment column 1003 is provided inside the first guide groove 1002, a second moving frame 1005 is fixedly connected to the lower surface of the first fixed plate 1001 through a second moving plate 1004, a first detection probe 1006 is provided on the second moving frame 1005, the rear surface of the first adjustment column 1003 is fixedly connected to the first moving plate 9, and the side surface of the guide support column 6 is slidably connected to the first moving plate 9.

[0029] Specifically, the inclined setting of the first guide groove 1002, combined with the linkage between the first adjusting column 1003 and the first moving plate 9, transforms the single driving action of the cylinder 8 into the reverse displacement of the probe. This allows the probe to be fitted with the side wall of the guide rail pair without manual adjustment of its position. At the same time, the sliding cooperation between the second moving plate 1004 and the first guide slide rail 12 further improves the stability and positioning accuracy of the movement of the first detection probe 1006, ensuring that the contact pressure between the probe and the side wall of each workpiece is consistent when multiple sets of guide rail pairs are continuously tested, thus guaranteeing the accuracy and consistency of the test data.

[0030] The second probe adjustment assembly 11 includes a second fixed plate 1101, a second guide groove 1102 is provided inside the second fixed plate 1101, a second adjustment column 1103 is provided inside the second guide groove 1102, a third moving frame 1105 is fixedly connected to the lower surface of the second fixed plate 1101 through a third moving plate 1104, a second detection probe 1106 is provided on the third moving frame 1105, and the front surface of the second adjustment column 1103 is fixedly connected to the first moving plate 9.

[0031] Specifically, the second probe adjustment component 11 and the first probe adjustment component 10 are linked through the same first moving plate 9. Through the symmetrical inclined guide groove structure, the probes on both sides move in opposite directions synchronously under the drive of a single cylinder 8. No separate drive component is required. The synchronous reverse movement of the probes on both sides can complete the contact positioning of the left and right sides of the guide rail pair in one go. Under the action of the moving component 2, the probes are driven to move along the length direction of the guide rail pair, which can quickly complete the flatness detection of the left and right sides of multiple sets of guide rail pairs.

[0032] The side surface of the first movable frame 5 is fixedly connected with the first guide slide rail 12 and the second guide slide rail 13. The interior of the second movable plate 1004 is provided with the third slide groove 25, and the inner surface of the third slide groove 25 is slidably connected with the first guide slide rail 12. The interior of the third movable plate 1104 is provided with the fourth slide groove 26, and the inner surface of the fourth slide groove 26 is slidably connected with the second guide slide rail 13.

[0033] Specifically, the first guide rail 12 and the second guide rail 13 are distributed in parallel, providing guidance for the second moving plate 1004 and the third moving plate 1104, respectively. The second moving plate 1004 has a third sliding groove 25 inside, and the inner surface of the third sliding groove 25 is slidably connected to the first guide rail 12 to form a guiding fit. When the first probe adjustment component 10 moves with the first moving plate 9, the second moving plate 1004 slides along the first guide rail 12 through the third sliding groove 25. The inner surface of the fourth sliding groove 26 is slidably connected to the second guide rail 13, providing guiding constraints for the movement of the second probe adjustment component 11. The first guide rail 12 and the second guide rail 13 form a double guide through the guide support column 6 guiding the first moving plate 9, ensuring that the movement trajectory of the first probe adjustment component 10 and the second probe adjustment component 11 is accurate.

[0034] A buffer assembly 14 is fixedly connected to the upper surface of the testing table 1. A placement plate 16 is fixedly connected to the upper surface of the buffer assembly 14 via a mounting plate 15. A placement groove 17 is provided inside the placement plate 16. A high-efficiency rolling linear guide pair testing component 18 is provided inside the placement groove 17.

[0035] Specifically, the buffer assembly 14 is designed to ensure detection accuracy. It absorbs vibrations generated during the detection process, preventing vibrations from being transmitted to the workpiece and causing data distortion. This provides a stable detection environment for the high-efficiency rolling linear guide pair detection component 18. The placement plate 16 is the direct load-bearing component for the workpiece. The cross-sectional shape of the placement groove 17 precisely matches the bottom contour of the high-efficiency rolling linear guide pair detection component 18. The buffer assembly 14 consists of an electromagnetic actuator and a honeycomb aluminum-based auxiliary vibration-absorbing structure. Both the electromagnetic actuator and the honeycomb aluminum are existing technologies; this invention integrates them to optimize the vibration absorption effect. The electromagnetic actuator, as the main vibration suppression unit, has its coil winding rigidly connected to the guide rail base, enabling it to quickly respond to guide rail vibration signals and generate a reverse force, efficiently dissipating high-frequency vibration energy. The honeycomb aluminum-based auxiliary vibration-absorbing structure, as an auxiliary unit, mainly absorbs mid-to-low frequency vibrations, forming a synergistic effect of full-band vibration suppression with the electromagnetic actuator.

[0036] The mounting plate 15 and the placement plate 16 are respectively provided with a first threaded mounting hole 19 and a second threaded mounting hole 20. The inner surface of the first threaded mounting hole 19 is threaded with a mounting bolt 21, and the inner surface of the second threaded mounting hole 20 is threaded with the mounting bolt 21.

[0037] Specifically, the diameter and thread specifications of the first threaded mounting hole 19 and the second threaded mounting hole 20 are consistent, which facilitates the adaptation of the universal mounting bolt 21. Through the tightening action of the mounting bolt 21, the mounting plate 15 and the placement plate 16 are firmly connected to the testing table 1. When it is necessary to replace the placement plate 16 of different specifications to adapt to different models of guide rail pairs, the placement plate 16 can be disassembled simply by unscrewing the mounting bolt 21. The operation is convenient and does not require any modification to the overall structure of the device. A spring washer and a flat washer are provided between the mounting bolt 21 and the mounting hole. The spring washer can provide preload to prevent the bolt from loosening due to vibration, while the flat washer can increase the contact area and reduce the pressure marks caused by the bolt on the mounting plate 15 and the placement plate 16.

[0038] The side surface of the testing table 1 is fixedly connected to the controller 23 via the connecting rod 22, and the lower surface of the testing table 1 is fixedly connected to the support frame 24.

[0039] Specifically, the connecting rod 22 is an adjustable folding rod, one end of which is welded and fixed to the testing table 1, and the other end is connected to the controller 23 by bolts. The operator can adjust the angle of the controller 23 according to their operating habits. The controller 23 integrates a PLC control module and a data processing module. The controller 23 is equipped with a display screen. In this application, the forward and reverse motor 205, the electric telescopic rod 4, the cylinder 8, the first detection probe 1006, the second detection probe 1106, and the display screen are all electrically connected to the controller 23. The controller 23 uniformly controls the opening, closing, and operation of each component. The opening and closing control method of each component is the prior art. The data processing module is used to receive multiple sets of electrical signals transmitted by the first detection probe 1006 and the second detection probe 1106. The method of the data processing module receiving and processing the probe electrical signals is the prior art. A support frame 24 is fixedly connected to the lower surface of the testing table 1. The support frame 24 is welded from four rectangular steel pipes to form a stable frame structure. The bottom of the support frame 24 is equipped with adjustable feet with M16 threads and an adjustment range of 0-50mm. It can be finely adjusted according to the flatness of the ground to ensure that the testing table 1 is placed horizontally. Rubber anti-slip pads are also provided at the bottom of the feet to increase the friction with the ground and at the same time play a role in vibration reduction.

[0040] Working principle: When using this device, multiple sets of high-efficiency rolling linear guide pair test pieces 18 to be tested are placed in the placement groove 17. The electric telescopic rod 4 is activated to extend and retract, causing the first moving frame 5 to move downward, so that the first test probe 1006 and the second test probe 1106 are moved to the height required for testing on both sides of the high-efficiency rolling linear guide pair test piece 18. The cylinder 8 is activated, and the output end of the cylinder 8 moves, causing the first moving plate 9, the first adjusting column 1003, and the second adjusting column 1103 to move. The first adjusting column 1003 and the second adjusting column 1103 are respectively located in the first guide groove 1002 and the second guide groove. 1102 moves inward, the second moving plate 1004 slides on the first guide slide rail 12, and the third moving plate 1104 slides on the second guide slide rail 13. The movement of the second moving plate 1004 and the third moving plate 1104 drives the first detection probe 1006 on the second moving frame 1005 and the second detection probe 1106 on the third moving frame 1105 to move in opposite directions, so that the first detection probe 1006 and the second detection probe 1106 contact the left and right outer walls of the high-efficiency rolling linear guide pair detection component 18. The flatness of the outer wall can be detected by the first detection probe 1006 and the second detection probe 1106. Simultaneously, multiple first detection probes 1006 and second detection probes 1106 are positioned to contact the left and right outer walls of multiple sets of high-efficiency rolling linear guide pair detection components 18. When the forward and reverse motors 205 are activated, the output of the motors 205 rotates, driving the lead screw 204 to rotate. The slider 203 moves within the first groove 202. The movement of the first detection probes 1006 and second detection probes 1106 allows for flatness detection of the outer wall of the high-efficiency rolling linear guide pair detection component 18. This structural arrangement allows for rapid adjustment of the first probe adjustment component 10 and the second probe adjustment component 11 to synchronously move closer to or further away from the guide pair to be tested, thus achieving flatness detection of the high-efficiency rolling linear guide pair to be tested. The rapid limiting and detection of different height positions on the left and right sides of the guide rail pairs eliminates the need for manual disassembly, adjustment of the guide rail pair direction, and repeated fixing by operators, simplifying the detection operation steps and reducing the labor intensity of operators. It can also quickly detect different height positions on the left and right ends of multiple sets of guide rail pairs, shortening the detection interval of a single set and improving the overall detection efficiency of high-efficiency rolling linear guide rail pairs, meeting the detection requirements of high-efficiency mass production. Furthermore, by using cylinder 8 as a common power source, it can achieve rapid limiting and detection of multiple sets of guide rail pairs to be tested, eliminating the need to configure a separate drive component for each set of tests, thus reducing the number of drive components and the space occupied.
