Description

Technical Field

[0001] This utility model relates to the field of robotic arms, specifically to a robotic arm with an adjustable tilt angle. Background Technology

[0002] A robotic arm is a mechanical device that mimics the movements of a human hand. It typically consists of a series of connected joints and actuators. Robotic arms can be used to complete automated tasks and are widely used in industries such as manufacturing, medicine, services, and agriculture. However, existing robotic arms still have certain shortcomings in their use. During use, most robotic arms on the market move the workpiece or worktable in both directions to achieve precise machining of the workpiece. However, for inclined surfaces of the workpiece, the angle of the workpiece on the worktable needs to be readjusted to meet the machining requirements of inclined surfaces. This requires repeated disassembly and adjustment of the workpiece, which affects the machining speed.

[0003] To overcome the aforementioned deficiencies, the prior art (Chinese Patent No. CN219521276U, Publication Date: August 15, 2023) provides a horizontal milling and boring machine with an easily adjustable tilt angle. This machine's tilting mechanism allows the mounting base to rotate via its central axis, enabling the mounting base to adjust the tilt angle of the workpiece on its surface according to processing requirements. This improves the processing efficiency of the machine. A support mechanism further assists in adjusting the tilt angle of the mounting base, enhancing its stability. A fixing mechanism quickly clamps and mounts the workpiece onto the surface of the mounting base, preventing workpiece displacement during tilt angle adjustment. Therefore, the machine's processing efficiency and effectiveness are both improved.

[0004] While existing technologies can meet the processing requirements of inclined surfaces on workpieces, the complex tilting and support mechanisms used to adjust the angle of the mounting base during operation increase the overall manufacturing and assembly difficulty, leading to a significant increase in maintenance costs and complexity. Furthermore, after prolonged processing, the tilt angle of the workpiece may become unstable, affecting processing accuracy and results. Additionally, adjusting the overall angle of the mounting base affects its stability, and uneven distribution of the support force can cause processing errors, impacting the quality of the workpiece processing.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing tiltable robotic arms. Therefore, we proposed a tiltable robotic arm that can effectively solve these problems. Utility Model Content

[0006] The purpose of this invention is to provide a tiltable robotic arm to address the aforementioned issues raised in the background art. Currently, the complex tilting and support mechanisms used to adjust the angle of the mounting base in the market increase manufacturing and assembly difficulty, leading to significantly higher maintenance costs and complexity. Furthermore, after prolonged processing, the tilt angle of the workpiece may become unstable, affecting processing accuracy and quality. Additionally, adjusting the overall angle of the mounting base affects its stability, and uneven distribution of the mounting base's support force can cause processing errors, impacting the quality of the workpiece.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tiltable robotic arm, comprising a processing base, a processing table for workpiece positioning on the processing base, a drive motor inside the processing base, a rotating base connected to the output end of the drive motor via a rotating shaft, the rotating base being connected through the processing base, a support frame connected to the rotating base via a drive assembly, a processing part for workpiece processing on the support frame, an arc-shaped seat on the support frame, and a threaded hole penetrating through the support frame and the arc-shaped seat, the threaded hole being arc-shaped, a fixing screw penetrating through the processing part, the fixing screw being adapted to the threaded hole.

[0009] Preferably, the machining base is equipped with an auxiliary component, which includes a conveyor installed inside the machining base.

[0010] Preferably, the output end of the conveyor is connected to a transmission pipe, the transmission pipe is located at the inner top of the processing base, and the transmission pipe has a through hole.

[0011] Preferably, the processing base is provided with an airbag, and the conveying component is connected to the airbag through a transmission pipe.

[0012] Preferably, the airbag output end is connected to a delivery pipe, the delivery pipe passes through the side wall of the processing seat and is connected to the auxiliary head, the auxiliary head is mounted on the support frame and is located at the side end of the processing workpiece.

[0013] Preferably, the outer side of the rotating shaft is connected to a positive and negative screw via a driving component, and a pressure plate is provided on the outer side of the positive and negative screw.

[0014] Preferably, the pressure plate moves inside the processing seat via a slider and a groove, and the pressure plate comes into contact with the airbag after it moves.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This tiltable robotic arm uses a drive motor to rotate a rotating base via a rotating shaft, and a telescopic cylinder inside the support base to move the support frame, thereby moving the workpiece to the workpiece surface. The overall structure is simple, reducing the cost increase caused by complex structures for adjusting the machining table angle, improving the overall workpiece machining quality, reducing the instability of the tilt angle that may occur when rotating the workpiece, and ensuring machining accuracy. The specific details are as follows:

[0016] The telescopic arm at the end of the rotating arm facilitates the movement of the support base, reducing the inconvenience caused by multiple clamping and multi-angle machining. The support frame drives the workpiece to the workpiece surface. The overall structure is simple, reducing the cost increase caused by setting up complex structures to adjust the machining table angle, and reducing the problem of unstable tilt angle that may occur when rotating the workpiece.

[0017] The conveyor transports gas through the transmission pipe and ejects it through the through hole at the top of the transmission pipe, allowing the gas inside the processing table to flow. This facilitates cooling of the processing table, prevents workpiece deformation due to overheating, and extends the service life of the equipment.

[0018] The transmission pipe delivers gas unidirectionally into the airbag, which in turn delivers gas unidirectionally into the transmission pipe. The gas is then ejected through an auxiliary head to provide targeted cooling and debris removal to the side of the workpiece, thereby improving the processing quality.

[0019] When the drive motor drives the rotating seat to rotate via the rotating shaft, the outer side of the rotating shaft drives the positive and negative screws to rotate via the drive component. The overall structure is simple, which facilitates later maintenance and reduces the problem of increased overall cost due to the need to set up additional drive structures.

[0020] The pressure plate on the outside of the positive and negative screws moves laterally through the cooperation of the slider and the slide groove, so that the pressure plate comes into contact with the air bag, making the pressure of the gas delivered inside the air bag adjustable, thereby improving the overall cooling and cleaning efficiency.

[0029] 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.

[0030] Example 1: In this example, the rotating arm 6 facilitates angle rotation, expanding the overall processing coverage, reducing the inconvenience caused by multiple clamping operations for multi-angle processing, greatly saving clamping time, and improving processing efficiency. Figures 1-5The technical solution shown includes a machining base 1, a machining table 2 for workpiece positioning on the machining base 1, a drive motor 3 inside the machining base 1, and a rotating seat 5 connected to the output end of the drive motor 3 via a rotating shaft 4. The rotating seat 5 is connected through the machining base 1, and a support frame 9 is connected to the rotating seat 5 via a drive assembly. A machining part 10 for workpiece processing is mounted on the support frame 9, and an arc-shaped seat 12 is mounted on the support frame 9. A threaded hole 11 is formed through the support frame 9 and the arc-shaped seat 12. The threaded hole 11 is arc-shaped. Assume that a fixing screw 13 is connected through the workpiece 10, and the fixing screw 13 is adapted to the threaded hole 11. The drive assembly includes a rotating arm 6 mounted on a rotating base 5, a telescopic arm 7 at the end of the rotating arm 6, and a support base 8 at the end of the telescopic arm 7. The support base 8 is connected to the top of the support frame 9 through an internal telescopic cylinder. The workpiece to be processed is placed on the processing table 2, and the drive motor 3 inside the processing base 1 is turned on. The drive motor 3 drives the rotating base 5 to rotate through the rotating shaft 4, so that the upper rotating arm 6 can easily rotate at an angle. This design expands the overall processing coverage, reduces the inconvenience caused by multiple clamping operations for multi-angle processing, significantly saves clamping time, and improves processing efficiency. The telescopic arm 7 at the end of the rotating arm 6 facilitates the movement of the support base 8. The telescopic cylinder inside the support base 8 drives the support frame 9 to move, allowing the support frame 9 to move the workpiece 10 to the workpiece surface. The overall structure is simple, reducing the cost increase caused by setting up complex structures to adjust the angle of the processing table 2. Furthermore, the processing table 2 is stable, reducing the problem of uneven distribution of support force caused by the angle rotation of the processing table 2, thus improving the overall quality of workpiece processing. When the fixing screw 13 is unscrewed from the threaded hole 11 of the support frame 9, the sliding block on the outside of the fixing screw 13 can slide inside the arc-shaped seat 12 on the support frame 9. After the workpiece 10 is rotated to the required position, the cooperation between the fixing screw 13 and the threaded hole 11 limits the workpiece 10. The overall processing angle is accurately positioned by the movement of the workpiece 10, reducing the problem of unstable tilt angle that may occur when rotating the workpiece and ensuring processing accuracy.

[0031] Example 2: In this example, gas is ejected from the auxiliary head 19 to specifically cool and remove debris from the side of the workpiece 10, thereby improving the processing quality. Specifically, as follows... Figures 3-6As shown, an auxiliary component is installed inside the machining base 1. This auxiliary component includes a conveyor 14 installed inside the machining base 1. The output end of the conveyor 14 is connected to a transmission pipe 15, which is located at the inner top of the machining base 1. A through hole 16 is provided on the transmission pipe 15. An airbag 17 is installed inside the machining base 1. The conveyor 14 is connected to the airbag 17 via the transmission pipe 15. The output end of the airbag 17 is connected to a conveyor pipe 18, which penetrates the side wall of the machining base 1 and connects to an auxiliary head 19. The auxiliary head 19 is mounted on a support frame 9 and is located at the side end of the machining part 10. When the conveyor 14 is opened, the conveyor 14 of this application... As a gas delivery mechanism, it can deliver gas or coolant as needed, improving the overall practicality. The delivery component 14 transmits gas through the transmission pipe 15 and ejects it through the through hole 16 at the upper end of the transmission pipe 15, allowing the gas inside the processing seat 1 to flow, facilitating the cooling operation of the processing table 2, preventing workpiece deformation on the processing table 2 due to overheating, and extending the service life of the equipment. In addition, the transmission pipe 15 delivers gas unidirectionally to the air bag 17, and the air bag 17 delivers gas unidirectionally to the transmission pipe 18, and ejects it through the auxiliary head 19, which performs targeted cooling and debris removal on the side of the processed workpiece 10, improving the processing quality.

[0032] Example 3: In this example, the pressure plate 22 on the outer side of the positive and negative screws 21 moves laterally through the cooperation of the slider and the groove, causing the pressure plate 22 to compress the air bag 17, thereby improving the overall cooling and cleaning efficiency. Specifically, as shown below... Figures 3-7 As shown, a positive and negative screw 21 is connected to the outside of the rotating shaft 4 via a drive component 20. A pressure plate 22 is provided on the outside of the positive and negative screw 21. The pressure plate 22 moves inside the processing base 1 through a slider and a sliding groove. After the pressure plate 22 moves, it contacts the airbag 17. When the drive motor 3 drives the rotating base 5 to rotate through the rotating shaft 4, the outside of the rotating shaft 4 drives the positive and negative screw 21 to rotate through the drive component 20. The drive component 20 of this application is a vertically meshing bevel gear, which converts vertical rotation into horizontal rotation. The overall structure is simple, convenient for later maintenance, and reduces the problem of increased overall cost due to the need to set up an additional drive structure. The pressure plate 22 on the outside of the positive and negative screw 21 moves laterally through the cooperation of the slider and the sliding groove, so that the pressure plate 22 contacts the airbag 17, making the gas pressure inside the airbag 17 adjustable, thereby improving the overall cooling and cleaning efficiency.
