Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically an industrial robot base structure. Background Technology

[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines widely used in industrial fields. They possess a certain degree of automation and can perform various industrial processing and manufacturing functions by relying on their own power and control capabilities. Industrial robotic arms are one of the most common types of industrial robots. The base structure of the robotic arm bears the entire weight of the robotic arm body (including all links, joints, and end effectors) and also bears dynamic loads: during high-speed movement, acceleration, and deceleration, it bears inertial forces, centrifugal forces, and torques. Vibrations transmitted from the external environment (such as vibrations from nearby equipment or the ground) can affect the accuracy of the robotic arm, accelerate component wear, or cause resonance. To address this, an industrial robot base structure is proposed to reduce the impact of external vibrations on the robotic arm. Utility Model Content

[0003] The purpose of this invention is to provide an industrial robot base structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An industrial robot base structure, comprising:

[0006] The frame has several support legs installed at the bottom, which are used to fix it to the ground.

[0007] A bushing is used to connect with the main body of the robot arm. A rotary bearing is fixedly installed between the bushing and the fixed frame. An internal gear ring is fixedly installed at the bottom end of the bushing.

[0008] A flange ring is fixedly installed on the outer side of the top end of the bushing, and the flange ring is used to fix the connection with the main body of the robotic arm;

[0009] A noise reduction component is disposed between the fixing frame and the flange ring, and the noise reduction component is used to reduce the propagation of vibration between the fixing frame and the flange ring.

[0010] Furthermore, a contact ring is provided on the outer side of the flange ring, and the contact ring is slidably connected to the noise reduction component.

[0011] Furthermore, the noise reduction component includes a rubber drum ring, a contact frame is fixedly installed at the top of the rubber drum ring, an oil groove is formed on the top surface of the contact frame, a lubrication frame is fixedly installed on the bottom surface of the contact ring, the lubrication frame is embedded in the oil groove and slidably connected to the oil groove, and the oil groove is coated with lubricating oil.

[0012] Furthermore, a metal gasket is fixedly connected to the bottom end of the rubber drum ring, and a flexible pad is installed at the bottom end of the metal gasket. The metal gasket is used to shape the bottom end of the rubber drum ring.

[0013] Furthermore, the flange ring has multiple clearance grooves equidistantly provided on its outer side, multiple snap-fit ​​grooves equidistantly provided on its bottom outer side, and multiple threaded parts equidistantly provided on the inner wall of the contact ring. The outer contour of the threaded parts fits the clearance grooves and snap-fit ​​grooves, and the number of threaded parts, snap-fit ​​grooves, and clearance grooves is the same.

[0014] Furthermore, the bushing has multiple positioning grooves inside.

[0015] Furthermore, the top end of the contact ring is fixedly connected to an outer ring portion, and the outer side wall of the contact ring is provided with a shielding portion.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting up the noise reduction component, the noise reduction component is located on the periphery of the bushing. The noise reduction component absorbs the vibration of the fixed frame and reduces the vibration amplitude of the fixed frame. At the same time, it absorbs the vibration of the bushing, reducing the impact of external vibration on the main body of the robotic arm. Meanwhile, the rubber drum ring surrounds the bushing, thereby reducing the outward transmission of noise inside the bushing.

[0018] 2. By setting the contact ring, when the noise reduction component needs to be removed, the position of the contact ring is adjusted so that the threaded part moves from the snap-fit ​​groove to the clearance groove, and the snap-fit ​​between the contact ring and the flange ring is released, so that the contact ring can be directly removed upwards, which facilitates the installation and removal of the noise reduction component and facilitates the maintenance of the noise reduction component.

Detailed Implementation

[0025] 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 protection scope of the present utility model.

[0026] Please see Figures 1-4 In this embodiment of the present invention, an industrial robot base structure includes a fixed frame 100, a flange ring 200, a bushing 300, and a noise reduction component 400. Several support legs 110 are mounted on the bottom of the fixed frame 100 for fixing to the ground. The bushing 300 is used to engage with the main body of the robot arm. A slewing bearing 500 is fixedly installed between the bushing 300 and the fixed frame 100. An internal toothed ring 320 is fixedly installed at the bottom end of the bushing 300. The flange ring 200 is fixedly installed on the outer side of the top end of the bushing 300 and is used for fixed connection to the main body of the robot arm. The noise reduction component 400 is disposed on the fixed frame 100. Between the fixed frame 100 and the flange ring 200, the noise reduction component 400 is used to reduce the transmission of vibration between the fixed frame 100 and the flange ring 200. A contact ring 230 is provided on the outer side of the flange ring 200. The contact ring 230 is slidably connected to the noise reduction component 400. The noise reduction component 400 includes a rubber drum ring 410. A contact frame 430 is fixedly installed on the top of the rubber drum ring 410. An oil groove 431 is opened on the top surface of the contact frame 430. A lubrication frame 232 is fixedly installed on the bottom surface of the contact ring 230. The lubrication frame 232 is embedded in the oil groove 431 and slidably connected to the oil groove 431. The oil groove 431 is coated with lubricating oil.

[0027] Specifically, the lubrication frame 232 is used to reduce friction with the rubber drum ring 410. The motor inside the robotic arm is connected to the internal gear ring 320, thereby driving the robotic arm to rotate. The vibration of the ground is transmitted to the support leg 110 through the support leg 110. The vibration of the support leg 110 is transmitted to the main body of the robotic arm through the slewing bearing 500, the bushing 300, and the flange ring 200. With the noise reduction component 400, which is located around the bushing 300, the noise reduction component 400 absorbs the vibration of the fixed frame 100, reducing the vibration amplitude of the fixed frame 100. At the same time, it absorbs the vibration of the bushing 300, reducing the impact of external vibration on the main body of the robotic arm. Meanwhile, the rubber drum ring 410 surrounds the bushing 300, thereby reducing the outward transmission of noise from inside the bushing 300.

[0028] Example 1

[0029] like Figures 3-5 As shown, in this embodiment, a metal gasket 420 is fixedly connected to the bottom end of the rubber drum ring 410, and a flexible pad 421 is installed at the bottom end of the metal gasket 420. The metal gasket 420 is used to shape the bottom end of the rubber drum ring 410. Multiple clearance grooves 210 are equidistantly provided on the outer side of the flange ring 200, and multiple snap-fit ​​grooves 220 are equidistantly provided on the outer side of the bottom surface of the flange ring 200. Multiple toothed portions 231 are equidistantly provided on the inner wall of the contact ring 230. The outer contour of the toothed portion 231 fits the clearance grooves 210 and the snap-fit ​​grooves 220. The number of toothed portions 231, snap-fit ​​grooves 220 and clearance grooves 210 is the same. Multiple positioning grooves 310 are provided inside the bushing 300. An outer ring portion 234 is fixedly connected to the top end of the contact ring 230, and a shielding portion 233 is provided on the outer wall of the contact ring 230.

[0030] In this embodiment, the rubber material of the rubber drum ring 410 gives it deformation capability. When installing or removing bolts on the flange ring 200, tools or manual pressing can be used to press the contact ring 230 downwards, causing the rubber drum ring 410 to bend downwards and expose the bottom of the flange ring 200, facilitating bolt operation. With the setting of the threaded part 231 and the clearance groove 210, when the noise reduction component 400 needs to be removed, the position of the contact ring 230 is adjusted so that the threaded part 231 moves from the snap-fit ​​groove 220 to the clearance groove 210, releasing the snap-fit ​​between the contact ring 230 and the flange ring 200, allowing the contact ring 230 to be directly removed upwards. This facilitates the installation and removal of the noise reduction component 400 and its maintenance. The shielding part 233 shields the gap between the contact ring 230 and the contact frame 430, reducing dust ingress.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
