Description

Technical Field

[0001] This utility model relates to the field of rotating mechanism technology, specifically a rotating mechanism for a 3D printed robot. Background Technology

[0002] 3D printing is typically achieved using digital technology material printers. It is often used in mold making, industrial design and other fields to create models, and is gradually being used for the direct manufacturing of some products. This technology has applications in industrial design, architecture, engineering and construction (AEC), automotive, aerospace, education, civil engineering and other fields. When 3D printing is performed, a rotating mechanism is often needed to drive the robotic arm of the 3D printing robot to rotate.

[0003] However, the existing rotary mechanisms mentioned above require multiple rotations to adjust the direction during robotic arm operation. Since existing rotary mechanisms rarely have anti-torsion mechanisms, repeated rotations will cause internal aging of the rotary mechanism. After aging, internal parts need to be replaced, which in turn affects processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a rotating mechanism for a 3D printed robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rotating mechanism for a 3D-printed robot includes a base and a rotating motor. The base includes a fixed seat and a base. The fixed seat has a base on its top. The base has an inner cavity. The rotating motor is fixedly connected to the bottom of the inner cavity. The top output end of the rotating motor is connected to a rotating rod. A through hole is formed at the center of the top of the base. The top of the rotating rod passes through the through hole and is located above the top of the base. Several reinforcing ribs are provided on the outer surface of the rotating rod. The bottom of the reinforcing ribs contacts the top of the base. A rotating disk is provided on the top of the several reinforcing ribs. The 3D-printed robot is fixedly connected to the rotating disk.

[0007] Preferably, a prompting block is provided on the top of the front surface of the outer surface of the base.

[0008] Preferably, the top of the base is provided with a first sliding groove, and a plurality of first sliding blocks are slidably connected to the first sliding groove, with the top of the first sliding blocks connected to the bottom of the reinforcing rib.

[0009] Preferably, a sliding disc is sleeved on the surface of the rotating rod and located in the inner cavity of the base. A second sliding groove is provided on the top of the sliding disc, and a second sliding block is slidably connected to the second sliding groove. The second sliding block is connected to the rotating rod.

[0010] Preferably, connecting rods are provided on both sides of the top of the sliding disk, and the top of the connecting rods is fixedly connected to the inner cavity of the base.

[0011] Preferably, the rear end of the second groove is filled with a sponge filler block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a rotating mechanism for a 3D-printed robot, which is equipped with reinforcing ribs. After the 3D-printed robot rotates, the sliding block under the reinforcing ribs will slide at the first slide groove, thereby better bearing the pressure generated by the bending of the 3D-printed robot's robotic arm. This prevents the rotation mechanism from being obstructed by the pressure of the robotic arm, improving torsional resistance. At the same time, after the 3D-printed robot rotates, the sliding block will also rotate along the second slide groove. When the second slide groove rotates to the sponge filling block, it will compress the sponge. The sponge has elasticity, which converts the pressure into the elastic force of the sponge's rebound, thus offsetting the pressure. The sponge filling block can enhance the torsional resistance and extend the service life. Attached Figure Description

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] A rotating mechanism for a 3D printed robot includes a base and a rotating motor 11. The base includes a fixed seat 1 and a base 2. The base 2 is located on the top of the fixed seat 1. An inner cavity is formed inside the base 2. The rotating motor 11 is fixedly connected to the bottom of the inner cavity of the base 2. The top output end of the rotating motor 11 is connected to a rotating rod 9. A through hole 7 is formed at the center of the top of the base 2. The top of the rotating rod 9 passes through the through hole 7 and is located above the top of the base 2. Several reinforcing ribs 5 are provided on the outer surface of the rotating rod 9. The bottom of the reinforcing ribs 5 is in contact with the top of the base 2. It should be noted that the reinforcing ribs 5 are made of high-strength alloy steel and are connected to the top of the rotating rod 9 by welding. They can withstand greater pressure. A rotating disk 4 is provided on the top of the several reinforcing ribs 5. The 3D printed robot is fixedly connected to the rotating disk 4.

[0023] Furthermore, a prompting block 3 is provided on the top of the front surface of the base 2. The prompting block 3 can remind the installer which part is the front of the base 2, making installation easier.

[0024] Furthermore, a first groove 6 is provided on the top of the base 2, and several first sliding blocks 8 are fitted and slidably connected at the first groove 6. The top of the first sliding blocks 8 is connected to the bottom of the reinforcing rib 5.

[0025] Specifically, when the 3D printing robot rotates, the sliding block 8 under the reinforcing rib 5 will slide at the first slide groove 6, which will not obstruct the rotation of the rotating mechanism and can better withstand the pressure generated after the 3D printing robot arm bends, avoiding the pressure of the robotic arm causing the rotating mechanism to be obstructed and improving torsional resistance.

[0026] Furthermore, a sliding disk 10 is sleeved on the surface of the rotating rod 9 and located in the inner cavity of the base 2. A second sliding groove 12 is provided on the top of the sliding disk 10. A second sliding block 13 is slidably connected to the second sliding groove 12 and is connected to the rotating rod 9.

[0027] Furthermore, connecting rods are provided on both sides of the top of the sliding disk 10, and the top of the connecting rods is fixedly connected to the inner cavity of the base 2.

[0028] Furthermore, the rear end of the second slide 12 is filled with a sponge filler block 14. Specifically, after the 3D printing robot rotates, the sliding block 8 will also rotate along the second slide 12. When the second slide 12 rotates to the sponge filler block 14, it will compress the sponge. The sponge is elastic and converts the pressure into the elastic force of the sponge's rebound, thus offsetting the pressure. The sponge filler block can enhance the anti-torsion performance and extend the service life.

[0029] Working principle: When using it, the base needs to be fixed first. Fix the base 1 to the appropriate place by fixing bolts through the fixing holes on the surface of the base 1. Then start the rotary motor 11 to make the 3D printing robot rotate. Specifically, after the rotary motor 11 rotates, the rotating rod 9 will rotate. The rotation of the rotating rod 9 will make the rotating disk 4 rotate. The rotation of the rotating disk 4 will make the 3D printing robot rotate, thus performing the operation.

[0030] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
