Abstract
Description
Technical Field
[0001] This utility model relates to the field of linear guide technology, and in particular to a linear guide adjustment device. Background Technology
[0002] Linear guides are crucial components in motion and are widely used in machine tools, automation equipment, and robotics. The precision of linear guides directly affects the motion accuracy and stability of the equipment; therefore, ensuring the accurate installation and adjustment of linear guides is of paramount importance.
[0003] In traditional linear guide installation, the two side rails typically need to remain stationary while the center rail moves. However, during the center rail's movement, it often shifts to one side, causing it to become non-parallel to the side rails and affecting the overall accuracy and performance of the guide system. Furthermore, existing guide adjustment methods are often complex, lack precision, and are prone to damaging the guide rails, hindering production efficiency and product quality assurance. Utility Model Content

Detailed Implementation
[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0029] Reference Figure 1 and 2 As shown, this utility model discloses a linear guide rail adjustment device, comprising:
[0030] Base plate 1;
[0031] Sensor module 2 is disposed on one side of the base plate 1 for measuring the distance of the linear guide rail 100; the sensor module 2 includes a sensor base 21 and a laser rangefinder 22 mounted on the sensor base 21, and the sensor base 21 is slidably mounted on a slide rail 23 fixed on the base plate 1.
[0032] A linear guide rail adjustment fixture 3 is mounted on the base plate 1 for mounting the linear guide rail 100 to be adjusted. The linear guide rail adjustment fixture 3 includes a platform base 31, a rotary support 32, a linear guide rail positioning seat 33, a clamping mechanism 34, and an adjusting screw 35. The platform base 31 is mounted on the base plate 1, the rotary support 32 is mounted on the platform base 31, the linear guide rail positioning seat 33 is mounted on the rotary support 32 and is parallel to the sensor module 2, and the adjusting screw 35 is mounted on the linear guide rail positioning seat 33. By rotating the adjusting screw 35, the position of the center rail 102 and the side rail 101 of the linear guide rail 100 in the linear guide rail positioning seat 33 can be adjusted.
[0033] like Figure 3 As shown, the rotating support 32 includes a support 321, a rotating connector 322, and a support plate 323. Both ends of the support plate 323 are mounted on the support 321 via the rotating connectors 322. The mounting of the support plate 323 to the support 321 via the rotating connectors 322 allows the support plate 323 to rotate within a certain range, facilitating the installation of the linear guide rail 100.
[0034] Based on the above structure, a through hole 3231 is provided in the middle of the support plate 323. The position of the through hole 3231 is designed to provide a channel on the support plate 323 so that the linear guide positioning seat 33 can be easily installed on the rotary support seat 32.
[0035] like Figure 4 As shown, the linear guide positioning seat 33 includes a base 331, a first side panel 332 and a second side panel 333. The first side panel 332 and the second side panel 333 are both vertically arranged on both sides of the base 331. The base 331 is provided with a plurality of locking holes for fixing the linear guide 100.
[0036] Furthermore, the second side panel 333 has a test reference surface 3331 on the side facing the laser rangefinder 22. The test reference surface 3331 serves as a reference plane for the laser rangefinder 22 during measurement, ensuring the accuracy and consistency of the measurement. The laser rangefinder 22 calculates the distance between the laser rangefinder 22 and the test reference surface 3331 by emitting a laser beam onto the test reference surface 3331 and receiving the reflected laser beam.
[0037] like Figure 5 As shown, the clamping mechanism 34 includes a support block 341 and a clamping head 342. The support block 341 is vertically mounted on the base plate 1. The clamping head 342 cooperates with the support block 341 to clamp and position the rotary support 32. The support block 341 provides support from the bottom of the rotary support 32. When the clamping head 342 is pressed down, the two cooperate to achieve horizontal clamping of the rotary support 32. This design ensures the stability of the rotary support 32 during adjustment.
[0038] The clamping head 342 includes a positioning seat 3421, an operating part 3422, and a clamping part 3423. The operating part 3422 and the clamping part 3423 are connected to the positioning seat 3421 via bolts and movable shafts, and the operating part 3422 and the clamping part 3423 are connected via bolts and movable shafts.
[0039] Furthermore, the clamping part 3423 includes a clamping rod 34231, a screw 34232, a fastening nut 34233, and a pressure nut 34234. The screw 34232 passes through the clamping rod 34231 and is locked and fixed by the fastening nut 34233. The pressure nut 34234 is disposed at the end of the screw 34232.
[0040] In addition, limit stops 12 are provided at both ends of the slide rail 23 to prevent the sensor base 21 from detaching from the slide rail 23 during sliding. This design improves the operational safety and stability of the device.
[0041] In this embodiment, a positioning step 11 is provided on the base plate 1 for fixing the platform base 31. The positioning step 11 is used to fix the platform base 31, ensuring the installation stability of the linear guide adjustment fixture 3. This design simplifies the installation process of the device and improves the versatility and applicability of the device.
[0042] To better understand the working principle of this embodiment, the following is a detailed explanation of its operation process:
[0043] Step 1: First, install the slide rail 23 on the base plate 1, ensuring that the slide rail 23 and the linear guide base are parallel. Then, install the linear guide 100 on the linear guide positioning seat 33, so that one of the side rails 101 of the linear guide 100 is close to the side of the linear guide positioning seat 33 near the slide rail 23. At the same time, lock and fix this side rail 101 to the linear guide positioning seat 33, and the other side rail 101 abuts against the adjusting screw 35.
[0044] Step two: Move the center rail 102 of the linear guide 100 to one extreme position. At this time, the laser range sensor 22 is aligned with the edge of the center rail 102 of the linear guide 100. Read the distance between the laser range sensor 22 and the center rail 102 of the linear guide 100 at this position.
[0045] Step 3: Then move the center rail 102 of the linear guide 100 to the other extreme position, and similarly move the laser range sensor 22 to the same side, aligning it with the edge of the center rail 102 of the linear guide 100 at this time, and read the distance reading between the laser range sensor 22 and the center rail 102 of the linear guide 100 at this time.
[0046] Step four: The two readings will have some difference. Then, use the adjusting screw 35 to adjust the distance between the middle rail 102 of the linear guide 100 and the laser range sensor 22 at the extreme positions at both ends. Repeat steps two and three until the distance between the middle rail 102 of the linear guide 100 and the laser range sensor 22 at the extreme positions at both ends is exactly the same. At this time, the middle rail 102 of the linear guide 100 is now completely parallel to the side rails 101.
[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
