Description

Technical Field

[0001] This utility model relates to the field of robot bases, and in particular to a robot base. Background Technology

[0002] As the basic supporting component of a robot system, the design of the robot base directly affects the robot's stability, functional expandability, and applicable scenarios.

[0003] The base provides rigid support for the robot body through a fixed connection with the ground or workbench.

[0004] However, once the existing robot base is fixed, the robot's position cannot be moved. If movement is required, it needs to be disassembled and reassembled, which is not only cumbersome but also limits the robot's working range.

[0005] Therefore, it is essential to invent a robot base. Utility Model Content

[0007] The linear electric guide rail includes a guide rail plate, a limiting groove, a lead screw, a motor, and a slide block. The limiting groove is formed through the surface of the guide rail plate. The lead screw is rotatably installed in the limiting groove. One end of the lead screw extends out from one end of the guide rail plate and is fixedly connected to the output end of the motor. The motor is fixedly installed at the output end of the electric rotary table. The slide block is sleeved on the lead screw and meshes with the lead screw. The slide block is slidably connected to the limiting groove.

[0009] A support wheel structure is fixedly installed at the end of the guide rail plate away from the motor, and the support wheel structure makes rolling contact with the annular base.

[0010] The mounting base is fixedly mounted on the slide block, and the mounting base is slidably connected to the upper surface of the guide rail plate;

[0011] The mounting base has mounting holes on its surface.

[0012] The annular base and the electric rotary table are fixedly connected by at least one connecting block.

[0013] A cavity is formed between the annular base and the electric rotary table and the connecting block.

[0014] The support wheel structure includes a ball seat and a ball. The ball seat is fixedly installed on the bottom surface of one end of the guide rail plate, and the ball is rotatably installed in the ball seat. A portion of the ball protrudes from the ball seat and rolls in contact with the annular base.

[0015] Two spheres are rotatably mounted on the bottom surface of the mounting base. Both spheres are distributed on both sides of the limiting groove, and the spheres are in rolling contact with the surface of the guide rail plate.

[0016] A control box is fixedly installed on one side of the annular base, and the controller inside the control box is electrically connected to the electric rotary table and the motor.

[0027] Example

[0028] Reference Figure 1-3 A robot base includes a linear electric guide rail, an annular base 1, an electric rotary table 2, and a mounting base 11. The electric rotary table 2 is coaxially fixed inside the annular base 1 so as to support the linear electric guide rail through the annular base 1 and the electric rotary table 2. At the same time, under the drive of the electric rotary table 2, the linear electric guide rail carries the mounting base 11 to rotate 360 ​​degrees along the annular base 1, thereby facilitating the adjustment of the overall position of the robot after installation.

[0029] Specifically, the linear electric guide rail includes a guide rail plate 5, a limiting groove 8, a lead screw 9, a motor 10, and a slide block 12. The limiting groove 8 is formed through the surface of the guide rail plate 5 to limit the lead screw 9 and ensure the stability of the lead screw 9 during rotation. The lead screw 9 is rotatably installed in the limiting groove 8. One end of the lead screw 9 extends out from one end of the guide rail plate 5 and is fixedly connected to the output end of the motor 10. The slide block 12 is sleeved on the lead screw 9 and meshes with the lead screw 9. The slide block 12 is slidably connected to the limiting groove 8 so that the motor 10 drives the lead screw 9 to rotate, causing the slide block 12 to drive the mounting base 11 to move linearly along the lead screw 9 and the limiting groove 8, thereby adjusting the robot's radius of motion on the annular base 1.

[0030] Specifically, the end of the guide rail plate 5 closest to the motor 10 is fixedly connected to the output end of the electric rotary table 2 by bolts in order to ensure the stability between the linear electric guide rail and the output end of the electric rotary table 2, so that the linear electric guide rail can rotate with the electric rotary table 2.

[0031] Specifically, a support wheel structure is fixedly installed at the end of the guide rail plate 5 away from the motor 10. The support wheel structure makes rolling contact with the annular base 1 so as to support the linear electric guide rail through the support wheel structure, ensuring the stability between the linear electric guide rail and the annular base 1 and the smoothness of the rotation process.

[0032] Specifically, the mounting base 11 is fixedly welded to the slide 12, and the mounting base 11 is slidably connected to the upper surface of the guide rail plate 5 so that the mounting base 11 can drive the robot to move along the slide 12;

[0033] Specifically, the mounting base 11 has mounting holes 14 on its surface for connecting to the robot.

[0034] Specifically, the annular base 1 and the electric rotary table 2 are fixedly connected by at least one connecting block 3. In this case, a total of four connecting blocks 3 are provided to ensure the stability between the annular base 1 and the electric rotary table 2.

[0035] Specifically, a cavity 4 is formed between the annular base 1, the electric rotary table 2, and the connecting block 3 to allow for good ventilation and heat dissipation between the electric rotary table 2 and the annular base 1.

[0036] Specifically, the support wheel structure includes a ball seat 6 and a ball 7. The ball seat 6 is fixedly installed on the bottom surface of one end of the guide rail plate 5, and the ball 7 is rotatably installed in the ball seat 6 so that the ball seat 6 can support the ball 7 and ensure the stability of the ball 7 during rotation. Part of the ball 7 protrudes from the ball seat 6 and rolls in contact with the annular base 1. By setting the ball 7, the friction between them can be reduced during the rotation of the linear electric guide rail along the annular base 1.

[0037] Specifically, two balls 13 are rotatably mounted on the bottom surface of the mounting base 11. Both balls 13 are distributed on both sides of the limiting groove 8. The balls 13 roll in contact with the surface of the guide rail plate 5. By setting the balls 13, the friction between them can be reduced when the mounting base 11 moves along the guide rail plate 5. At the same time, the weight of the mounting base 11 and the robot is distributed on the guide rail plate 5, preventing the weight of the mounting base 11 and the robot from acting directly on the lead screw 9.

[0038] Specifically, a control box is fixedly installed on one side of the annular base 1, and the controller inside the control box is electrically connected to the electric rotary table 2 and the motor 10.

[0039] The controller is a PLC controller, and the output of the PLC controller is electrically connected to the electric rotary table 2 and the motor 10.

[0040] In this embodiment, during use, the annular base 1 and the electric rotary table 2 are fixedly installed on the plane, and then the robot is fixedly installed on the mounting base 11 through the mounting hole 14 and the bolts.

[0041] When the position of the robot needs to be adjusted later, the linear electric guide rail driven by the electric rotary table 2 can carry the mounting base 11 and the robot to rotate 360 ​​degrees along the ring base 1 until the robot moves to the desired position.

[0042] Simultaneously, the motor 10 can drive the lead screw 9 to rotate, causing the slide 12 to drive the mounting base 11 to move linearly along the lead screw 9 and the limiting groove 8, thereby adjusting the robot's radius of motion on the annular base 1.

[0043] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
