Description

Technical Field

[0001] The utility model relates to the technical field of linear drive, in particular to a support structure for a translation slide table. Background Art

[0002] Linear modules are widely used in various mechanical devices, such as processing equipment, detection equipment, intelligent equipment, and robotic arms, for connecting actuators and driving the actuators to perform linear displacement. Existing linear modules generally include synchronous belt modules, linear motor modules, and ball screw modules. Chinese Patent CN202222072956.5 discloses a linear motor based on a high-precision positioning structure. The transmission elements include a linear track and a linear slider slidably installed on the linear track. A moving seat is fixedly installed on the linear slider, and the moving seat can move along the linear track following the linear slider. The linear track is symmetrically supported on both sides of the moving seat. Since the linear guide rail has extremely high flatness accuracy requirements for the installation plane, usually a high-precision machined part is used as the base, resulting in high costs and great processing difficulties. Therefore, higher installation accuracy requirements are imposed on the two linear guide rails and the lead screw. Once the parallelism of the two linear guide rails does not meet the standard, it is extremely easy to generate abnormal noises or even jams, and the installation and debugging are difficult, and the processing and debugging costs are high.

Detailed implementation mode

[0018] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] As Figures 1 to 3 shown, this embodiment discloses a translation stage support structure, which includes a base 1, a guide rail assembly and a guide wheel assembly. The guide rail assembly includes a linear guide rail 2 and a slider 3 slidably connected to the linear guide rail 2. The linear guide rail 2 is installed on one side of the base 1. The guide wheel assembly includes a square guide rail 4 and a roller group rollingly connected to the square guide rail 4. The square guide rail 4 is installed on the other side of the base 1. One end of the slider 3 is slidably connected to the linear guide rail 2, the other end of the slider 3 is fixedly connected to the stage 13, the roller group is rollingly connected to the square guide rail 4, and the roller group is fixedly connected to the stage 13, so that the stage 13 moves smoothly under the drive of the slider 3 and the roller group. By taking the linear guide rail 2 provided on one side of the base 1 as the main part to provide positioning accuracy, the square guide rail 4 on the other side of the base 1 cooperates to adjust the roller group, strengthening the bearing capacity and the structural rotation torque load to adapt to the installation platform with lower machining accuracy requirements, reducing the installation and adjustment difficulty, reducing costs and reducing failures.

[0020] As Figure 3 shown, the roller group includes a roller 5, a first connecting rod 6 and a second connecting rod 7. The outer peripheral wall of the roller 5 is rollingly connected to the square guide rail 4, the inner ring of the roller 5 is rotatably connected to the first connecting rod 6, and the second connecting rod 7 is fixedly connected to the first connecting rod 6. One end of the second connecting rod 7 is fixedly connected to the first connecting rod 6, and the other end of the second connecting rod 7 is fixedly connected to the stage 13. The roller 5 drives the stage 13 to move through the first connecting rod 6 and the second connecting rod 7. The roller 5 is of a bearing structure. The first connecting rod 6 is concentrically arranged with the roller 5, and the second connecting rod 7 is eccentrically arranged with the first connecting rod 6. The first connecting rod 6 and the second connecting rod 7 of the roller 5 are not concentrically arranged. The distance between the rotation center of the roller 5 and the square guide rail 4 can be adjusted by adjusting the installation angle of the second connecting rod 7.

The second connecting rod 7 can be a screw rod. The second connecting rod 7 sequentially passes through the stage 13, the first support plate 11 and the first connecting rod 6. The area of the first support plate 11 is relatively large, playing a role in stably supporting the stage 13.

[0022] As Figure 3 and 4As shown, the first connecting rod 6 includes a first limiting block 8, a rotating rod 9, and a second limiting block 10 connected in sequence. The inner ring of the roller 5 is rotatably sleeved on the outer peripheral wall of the rotating rod 9. The first limiting block 8 is located on one side of the inner ring of the roller 5, and the second limiting block 10 is located on the other side of the inner ring of the roller 5. The second connecting rod 7 is eccentrically arranged with the first limiting block 8. The first limiting block 8 and the second limiting block 10 limit both sides of the roller 5 to ensure that the roller 5 rolls along the length direction of the square guide rail 4. The number of the roller groups is two, and the two roller groups are respectively arranged to roll on both sides of the square guide rail 4. The roller groups are respectively arranged on both sides of the square guide rail 4, providing a more stable support for the sliding table 13.

[0023] As Figure 1 and 2 shown, the guide rail assembly further includes a second support plate 12 for abutting against the sliding table 13. The second support plate 12 is connected to the slider 3 by screws. The second support plate 12 has a relatively large area and plays a role in stably supporting the sliding table 13. There are multiple sets of the guide rail assembly and the guide wheel assembly respectively, and the guide rail assembly and the guide wheel assembly are arranged in one-to-one correspondence. A plurality of sliding tables 13 can be provided on the base 1 to improve work efficiency.
