Description

Technical Field

[0001] This utility model relates to the field of robot guide rail technology, specifically a guide rail device for industrial robots. Background Technology

[0002] A guide rail is a basic mechanical component used to support and guide moving parts to reciprocate along a predetermined path in a straight line or curve. It is usually composed of a guide rail body and a slider (or carrier body). It achieves low-friction, high-precision relative motion through sliding, rolling or magnetic levitation and is widely used in machine tools, automated equipment, robots and rail transportation.

[0003] Existing industrial robot guide rails, while using motors to drive the guide rails for lifting, lowering, and angle adjustment to expand the robot's working range, rely solely on the motor's self-locking mechanism and the friction between the threads to limit and fix the guide rail's height and position after adjustment. The motor and screw bear the weight of their own bodies, the guide rail, and the industrial robot, making them susceptible to damage under significant pressure and reducing the stability of the device. Therefore, this paper proposes an industrial robot guide rail device to address these issues. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An industrial robot guide rail device of this utility model includes a worktable, a support frame fixedly connected to the upper side of the worktable, a first motor fixedly connected to the upper side of the support frame, a lifting screw fixedly connected to the output end of the first motor, a lifting frame threadedly connected to the outer side of the lifting screw, the lifting frame and the support frame being slidably connected, a second motor fixedly connected to the inner side of the lifting frame, a guide rail fixedly connected to the output end of the second motor, a fixing block fixedly connected to one side of the guide rail, fixing grooves provided on the inner side of the lifting frame, the surface of the support frame, and the inner side of the fixing block, a hydraulic cylinder fixedly connected to the inner side of the worktable, a moving plate fixedly connected to the output end of the hydraulic cylinder, a circular frame slidably connected to the outer side of the moving plate, and the circular frame and the lifting frame being slidably connected. Both the movable plate and the circular frame are fixedly connected to a fixing rod, and the fixing groove and the fixing rod work together. This step involves setting up a fixing block, fixing groove, movable plate, and circular frame. The rotation of the lifting screw drives the lifting frame to move, which in turn drives the second motor, circular frame, fixing block, and guide rail to rise to a suitable height. The second motor then drives the guide rail and fixing block to rotate, allowing the guide rail to rotate to a suitable maximum height. A hydraulic cylinder then drives the movable plate to move, which in turn drives the circular frame to move. The movable plate and circular frame then drive the fixing rod to move, causing the fixing rod to insert into the fixing grooves inside the lifting frame, the support frame surface, and the fixing block. This further restricts and fixes the position of the lifting frame and the guide rail, distributing the pressure on the first motor, lifting screw, and second motor, making them less prone to damage and improving the stability of the device.

[0006] Preferably, a support plate is fixedly connected to the lower side of the movable plate, and a roller is rotatably connected to the inner side of the support plate. This step, by setting the support plate and the roller, allows the device to be installed in a suitable position. The roller can then provide further support to the support plate and the movable plate through the contact point between the worktable and the roller, thereby reducing the pressure on the movable plate supported by the hydraulic cylinder output end, making the operation of the hydraulic cylinder more stable, and improving the stability of the device.

[0007] Preferably, a retaining plate is fixedly connected to the outer side of the guide rail, and a reinforcing screw is slidably connected to the inner side of the retaining plate. A slot is formed on the inner side of the worktable. This step, by setting the retaining plate, the reinforcing screw, and the slot, allows the retaining plate to be further restricted and fixed in position after the guide rail angle is adjusted. This makes the position of the retaining plate more stable after adjustment and improves the stability of the device.

[0008] Preferably, a stop bar is fixedly connected to one side of the lifting frame, and the stop bar works in conjunction with the circular frame. This step, by setting the stop bar, ensures that when the circular frame moves to its maximum position, the stop bar intercepts and restricts it, making it difficult for the contact point between the circular frame and the lifting frame to separate, thereby improving the stability of the device operation.

[0009] Preferably, a limiting rod is slidably connected to the inner side of the lifting frame, and a spring is fixedly connected to the upper side of the worktable, with one end of the spring fixedly connected to the lifting frame. This step, by setting the limiting rod and the spring, further restricts the movement trajectory of the lifting frame by inserting the limiting rod into the inner side of the lifting frame, making the movement of the lifting frame more stable. When the lifting frame is raised or lowered, the spring itself provides further support for the lifting frame, thereby further distributing the pressure on the lifting screw and improving the stability of the device placement.

[0010] Preferably, a rotating rod is rotatably connected to the inner side of the workbench, and a mounting plate is fixedly connected to one end of the rotating rod. This step, by setting the rotating rod and the mounting plate, allows the mounting plate to be rotated to different orientations when the device is installed, such as when it is installed close to a wall, so that the opening on the surface of the mounting plate can be rotated to adapt to different installation environments, thereby improving the flexibility of device installation.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting a fixed block, a fixed groove, a movable plate, and a circular frame, moves the lifting frame by rotating the lifting screw. The lifting frame then raises the second motor, the circular frame, the fixed block, and the guide rail to a suitable height. The second motor then rotates the guide rail and the fixed block, causing the guide rail to rotate to a suitable maximum height. A hydraulic cylinder then moves the movable plate, which in turn moves the circular frame. The movable plate and the circular frame then move the fixed rod, causing the fixed rod to insert into the fixed grooves on the inner side of the lifting frame, the surface of the support frame, and the inner side of the fixed block. This further restricts and fixes the position of the lifting frame and the guide rail, distributing the pressure on the first motor, the lifting screw, and the second motor, making them less prone to damage and improving the stability of the device.

[0013] 2. By setting up a support plate and rollers, this utility model allows the device to be installed in a suitable position. The rollers can further support the support plate and the moving plate through the contact point between the worktable and the rollers, thereby reducing the pressure on the moving plate support at the output end of the hydraulic cylinder, making the operation of the hydraulic cylinder more stable and improving the stability of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown, a guide rail device for an industrial robot includes a worktable 1. A support frame 2 is fixedly connected to the upper side of the worktable 1. A first motor 3 is fixedly connected to the upper side of the support frame 2. A lifting screw 4 is fixedly connected to the output end of the first motor 3. A lifting frame 5 is threadedly connected to the outer side of the lifting screw 4. The lifting frame 5 and the support frame 2 are slidably connected. A second motor 6 is fixedly connected to the inner side of the lifting frame 5. A guide rail 7 is fixedly connected to the output end of the second motor 6. A fixing block 8 is fixedly connected to one side of the guide rail 7. Fixing grooves 9 are provided on the inner side of the lifting frame 5, the surface of the support frame 2, and the inner side of the fixing block 8. A hydraulic cylinder 10 is fixedly connected to the inner side of the worktable 1. A moving plate 11 is fixedly connected to the output end of the hydraulic cylinder 10. A circular frame 12 is slidably connected to the outer side of the moving plate 11. The circular frame 12 and the lifting frame 5 are slidably connected. Fixing rods are fixedly connected to one side of the moving plate 11 and one side of the circular frame 12. 101, the fixing groove 9 and fixing rod 101 are used in conjunction; this step involves setting a fixing block 8, fixing groove 9, moving plate 11 and circular frame 12, and rotating the lifting screw 4 to move the lifting frame 5, which in turn drives the second motor 6, circular frame 12, fixing block 8 and guide rail 7 to a suitable height. The second motor 6 then drives the guide rail 7 and fixing block 8 to rotate, allowing the guide rail 7 to rotate to a suitable maximum height. The hydraulic cylinder 10 then drives the moving plate 11 to move, which in turn drives the circular frame 12 to move. The moving plate 11 and circular frame 12 then drive the fixing rod 101 to move, allowing the fixing rod 101 to insert into the fixing groove 9 on the inner side of the lifting frame 5, the surface of the support frame 2 and the inner side of the fixing block 8. This further restricts and fixes the position of the lifting frame 5 and the guide rail 7, sharing the pressure on the first motor 3, lifting screw 4 and second motor 6, making them less prone to damage and improving the stability of the device.

[0024] Furthermore, such as Figure 2 and Figure 5 As shown, a support plate 13 is fixedly connected to the lower side of the movable plate 11, and a roller 14 is rotatably connected to the inner side of the support plate 13. This step, by setting the support plate 13 and the roller 14, allows the device to be installed in a suitable position. The roller 14 then provides further support to the support plate 13 and the movable plate 11 through the contact point between the workbench 1 and the roller 14. This reduces the pressure on the movable plate 11 supported by the output end of the hydraulic cylinder 10, making the operation of the hydraulic cylinder 10 more stable and improving the stability of the device.

[0025] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, a retaining plate 15 is fixedly connected to the outer side of the guide rail 7, and a reinforcing screw 16 is slidably connected to the inner side of the retaining plate 15. A slot 17 is opened on the inner side of the worktable 1. This step, by setting the retaining plate 15, the reinforcing screw 16, and the slot 17, allows the retaining screw 16 to be screwed into the retaining plate 15 and the slot 17 at different positions after the guide rail 7 is adjusted, thereby further restricting and fixing the position of the retaining plate 15, making the position of the guide rail 7 more stable after adjustment, and improving the stability of the device.

[0026] Furthermore, such as Figure 2 As shown, a baffle 18 is fixedly connected to one side of the lifting frame 5. The baffle 18 works in conjunction with the circular frame 12. By setting the baffle 18, when the circular frame 12 moves to its maximum position, the baffle 18 intercepts and restricts it, making it difficult for the circular frame 12 to separate from the lifting frame 5 at the contact point, thus improving the stability of the device operation.

[0027] Furthermore, such as Figure 1 and Figure 2 As shown, a limiting rod 19 is slidably connected to the inner side of the lifting frame 5, and a spring 20 is fixedly connected to the upper side of the worktable 1. One end of the spring 20 is fixedly connected to the lifting frame 5. This step, by setting the limiting rod 19 and the spring 20, further restricts the movement trajectory of the lifting frame 5 by inserting the limiting rod 19 into the inner side of the lifting frame 5, making the movement of the lifting frame 5 more stable. When the lifting frame 5 is raised or lowered, the spring 20 itself provides thrust to further support the lifting frame 5, thereby further distributing the pressure on the lifting screw 4 and improving the stability of the device placement.

[0028] Furthermore, such as Figure 1 As shown, a rotating rod 21 is rotatably connected to the inner side of the workbench 1, and a mounting plate 22 is fixedly connected to one end of the rotating rod 21. This step, by setting the rotating rod 21 and the mounting plate 22, allows the mounting plate 22 to be rotated to different orientations when the device is installed, such as when it is installed close to the wall, so that the opening on the surface of the mounting plate 22 can be rotated to different orientations to adapt to different installation environments, thereby improving the flexibility of device installation.

[0029] The working principle is as follows: the first motor 3 drives the lifting screw 4 to rotate, which in turn moves the lifting frame 5. The lifting frame 5 then drives the second motor 6, the circular frame 12, the fixing block 8, and the guide rail 7 to rise to a suitable height. The second motor 6 then drives the guide rail 7 and the fixing block 8 to rotate to a suitable height. The hydraulic cylinder 10 then drives the moving plate 11 to move, which in turn moves the circular frame 12. The moving plate 11 and the circular frame 12 then move the fixing rod 101, which inserts into the fixing groove 9 on the inner side of the lifting frame 5, the surface of the support frame 2, and the inner side of the fixing block 8. This further restricts and fixes the position of the lifting frame 5 and the guide rail 7. The reinforcing screw 16 is then screwed into the inner side of the clamping plate 15 in a suitable position. The rotation continues until the reinforcing screw 16 is screwed into the inner side of the clamping groove 17 in a suitable position, thus further restricting and fixing the position of the clamping plate 15 and the guide rail 7.
