Description

Technical Field

[0001] The utility model relates to the field of industrial robot applications, and particularly relates to a non-powered ground rail for industrial robots. Background Art

[0002] Industrial robots are a type of mechanical device widely used in industrial production, and are widely used in industrial fields such as metal forging, metal casting, welding, painting, and assembly.

[0003] In the use of industrial robots, the position layout of industrial robots and devices directly affects the realization and efficiency of automated production lines. Generally, the position layout principle is to first determine the position of the device, and then determine the position of the industrial robot accordingly. In some cases, due to the limitations of site space and the working radius of industrial robots, the position of the industrial robot needs to be adjusted to make room for maintenance space or other process requirements. For example, in a forging automated production line, when the industrial robot is installed in front of and behind the press device, during die change, the industrial robot will affect the operation of lifting devices such as forklifts. In previous working conditions, a lifting device was used to first lift the industrial robot and move it to other positions to make room for manual die change or maintenance space, which was inefficient, had a high manual labor intensity, and had potential safety hazards. Based on this, the utility model designs a non-powered ground rail for industrial robots to solve the above problems. Summary of the Utility Model

Detailed implementation manners

[0025] In order to make the purpose, technical solutions and advantages of the present application clearer, the following further details the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0027] In one embodiment, a power-free ground rail for an industrial robot is provided. The device includes a drag chain 1, a drag chain mounting plate 2, a handwheel pin hole seat 3, a screw hole seat 4, a flat steel wheel 5, a robot mounting seat 6, a handwheel pin 7, an H-shaped steel wheel 8, an anti-tipping block 9, a track 10, an anti-collision buffer block 11, and a hoisting ring 12. The robot mounting seat 6 is arranged above the track 10, and the industrial robot is installed above the robot mounting seat 6.

[0028] Furthermore, the track 10 is welded into a frame by two parallel national standard steel rails and square tube profiles. A perforated mounting plate is welded below the steel rails, and the track 10 can be fixed above the concrete floor through the perforated mounting plate.

[0029] Further, on both ends of the rail of the track 10, mounting blocks with threaded holes are welded for mounting the anti-collision buffer block 11. The anti-collision buffer block 11 is made of flexible materials such as polyurethane. When manually pushing the robot mounting seat 6 to switch between the working position and the non-working position, the impact force can be buffered.

[0030] Further, two flat steel wheels 5 and two H-shaped steel wheels 8 are mounted on the robot mounting seat 6. Openings are made at the positions of the steel wheel bodies on the robot mounting seat 6, and the lower circular surfaces of the steel wheels are sunk below the robot mounting seat 6, so that the flat steel wheels 5 and the H-shaped steel wheels 8 are in direct contact with the track 10 to support the robot mounting seat 6, enabling the robot mounting seat 6 to move back and forth on the track 10. The stepped structure of the H-shaped steel wheel 8 can ensure that the steel wheel does not deviate from the rail in the left-right direction during the movement.

[0031] Further, the H-shaped steel wheel 8 is composed of a steel wheel seat 21, a steel wheel shaft 22, an H-shaped wheel 23, and a bearing 24. The steel wheel seat 21 is fixed to the robot mounting seat 6 by screws, and the steel wheel seat 21, the steel wheel shaft 22, the H-shaped wheel 23, and the bearing 24 are assembled into a component through shaft-hole fitting.

[0032] Further, the flat steel wheel 5 is composed of a steel wheel seat 21, a steel wheel shaft 22, a flat wheel 28, and a bearing 24. The steel wheel seat 21 is fixed to the robot mounting seat 6 by screws, and the steel wheel seat 21, the steel wheel shaft 22, the flat wheel 28, and the bearing 24 are assembled into a component through shaft-hole fitting.

[0033] Further, two handwheel pins 7 are mounted on the robot mounting seat 6.

[0034] Further, the handwheel pin 7 is composed of a handwheel 25, a threaded pin 26, and a pin seat 27. The pin seat 27 is fixed to the robot mounting seat 6 by screws. External threads are machined in the upper-middle part of the threaded pin 26, which is threadedly connected to the upper part of the pin seat 27. The upper part of the threaded pin 26 is fixed to the handwheel 25 by screws. When the handwheel 25 is rotated, it drives the threaded pin 26 to rotate. Through the threaded transmission with the pin seat 27, the threaded pin 26 and the handwheel 25 move up and down, realizing the pin hole fitting and disengagement between the threaded pin 26 and the pin hole of the handwheel pin hole seat 3.

[0035] Further, a handwheel pin hole seat 3 and a screw hole seat 4 are welded and mounted on the track 10. A pin hole is machined on the handwheel pin hole seat 3 for pin hole fitting with the threaded pin 26; a threaded hole is machined on the screw hole seat 4, and the screw passes through the through hole machined on the robot mounting seat 6 to fix the robot mounting seat 6 on the screw hole seat 4.

[0036] Further, one end of a drag chain 1 is mounted below the robot mounting seat 6, and the other end of the drag chain 1 is mounted on the drag chain mounting plate 2. The drag chain 1 is located below the ground surface, and the drag chain mounting plate 2 can be fixed in the concrete.

[0037] Furthermore, a plurality of anti-tilt blocks 9 are installed on the left and right sides below the robot mounting seat 6. The anti-tilt blocks 9 are designed to imitate the contour of the rails, and are gap-matched with the rails on the left and right sides, and are stuck between the two rails to prevent the upper mounted components from tipping over when the robot mounting seat 6 moves forward and backward.

[0038] Furthermore, the anti-collision buffer block 11 is made of flexible materials such as polyurethane.

[0039] Furthermore, the step structure of the H-shaped steel wheel 8 can ensure that the steel wheel will not separate from the rail in the left-right direction during movement.

[0040] Furthermore, a plurality of anti-tilt blocks 9 are installed on the left and right sides below the robot mounting seat 6. The anti-tilt blocks 9 are designed to imitate the contour of the rails, and are matched with the gaps between the rails on the left and right sides, and are stuck between the two rails to prevent the upper mounted components from tipping over when the robot mounting seat 6 moves forward and backward.

[0041] Furthermore, the lower end of the threaded pin 26 is designed to be conical, which plays a guiding role when cooperating with the hand wheel pin hole seat 3.

[0042] Furthermore, threaded holes are processed around the rail 10 for installing the lifting ring 12 .

[0043] The implementation method of the non-powered ground rail for the industrial robot is as follows:

[0044] When in use, first fix the track to the concrete floor according to the layout diagram, manually push the robot mounting seat and the industrial robot to the working position, manually turn the handwheel pin, so that the threaded pin gradually enters the handwheel pin hole seat, and after the handwheel pin is in place, manually pass the fastening screw through the through hole on the robot mounting seat, fix the robot mounting seat on the screw hole seat, and fix the robot mounting seat on the track to achieve the positioning and fixation of the industrial robot. When the industrial robot needs to give up the maintenance space or other space required by other processes, manually remove the screws and handwheel pins, and then push the robot mounting seat and the industrial robot to the non-working position.

[0045] The novel device realizes the switching of the industrial robot between the working position and the non-working position by manually adjusting the position of the robot mounting seat on the track; and realizes the repeated positioning accuracy requirement of the industrial robot at the working position by positioning and locking the handwheel pin, the handwheel pin hole seat and the screw hole seat.
