Description

Technical Field

[0001] This application relates to the field of 3D metal printing technology, and in particular to a synchronous belt motor double rotating arm structure. Background Technology

[0002] 3D metal printing uses laser melting technology to melt metal powder to form functional solid parts. It is a fully digital rapid prototyping manufacturing process that directly produces high-density metal parts based on the interface data of each layer in 3D CAD. The thickness of the molten metal layer ranges from 20 micrometers to 100 micrometers. 3D metal printers are scientific instruments used in basic disciplines of physics, engineering and technology, and mechanical engineering.

[0003] However, the existing synchronous belt motor double rotating arm structure has certain limitations and simplistic single rotation during rotation, which reduces the overall practicality; and after the rotating arm is installed, certain gaps appear, which will cause wobbling during long-term use, thereby reducing the accuracy of the rotating arm. Summary of the Invention

[0004] In view of the above problems, this application provides a synchronous belt motor double rotary arm structure to solve the problems of the existing synchronous belt motor double rotary arm structure, which has certain limitations and single rotation during rotation, reducing the overall practicality; and the existence of gaps after installation of the rotary arm, which will cause wobbling during long-term use, thereby reducing the accuracy of the rotary arm.

[0005] This application provides a synchronous belt motor double rotary arm structure. It includes mounting turntables, with toothed grooves on the outer walls of the two turntables. A toothed belt is meshed with the surface of the toothed grooves, and pulleys are meshed with the inside of the toothed belts. A rotating rod is fixedly mounted through the bottom ends of the two pulleys, and a drive device is fixedly mounted at the bottom end of the rotating rod.

[0006] The above scheme drives the drive equipment to rotate the rotating rod, which in turn drives the pulley to rotate. The meshing of the two pulleys drives the toothed belt and tooth groove to rotate, and then the tooth groove drives the mounting turntable to rotate, thereby driving the arm to rotate and swing. The two toothed belts achieve dual-rotation synchronous rotation on both sides.

[0007] In some embodiments, the drive device is mounted inside the mounting frame.

[0008] The above solution provides stability for the meshing rotation between the pulley and the toothed belt by installing a frame, preventing external forces from affecting the rotation, and also providing a protective function.

[0009] In some embodiments, the mounting frame is connected to the mounting rings, and the two mounting rings are movably fitted onto the mounting turntable.

[0010] With the above solution, when the tooth groove rotates, it drives the mounting turntable to rotate, and the tooth groove rotates inside the mounting ring. Thus, the mounting ring provides stability for the meshing rotation between the tooth groove and the toothed belt, avoids external forces affecting the rotation, and also plays a protective role.

[0011] In some embodiments, an arm is mounted on the inner wall of the two mounting turntables, a rotating shaft is movably sleeved on the top of the two mounting turntables, a first bevel gear is fixedly mounted on one side of the two rotating shafts, a second bevel gear is meshed with the surface of the first bevel gear, a screw is fixedly mounted on one side of the second bevel gear, a threaded block is threadedly connected to the outer wall of the screw, and a limit ring is fixedly mounted on one side of the threaded block.

[0012] With the above scheme, when the mounting turntable and the arm body are installed together, turning the rotating shaft drives the first bevel gear to rotate, and the first bevel gear meshes with the second bevel gear to rotate, which in turn drives the screw to rotate, causing the threaded block to move threadedly on the screw surface. This pushes the limiting ring to slide out from the inner wall of the mounting turntable, and limits and clamps the outer wall of the arm body that is installed with the mounting turntable. The clamping of the limiting rings on both sides increases the contact area between the mounting turntable and the arm body, improving the stability and firmness of the installation.

[0013] In some embodiments, a plurality of gaskets are fixedly embedded in the inner wall of the limiting ring.

[0014] With the above solution, when the installation turntable and the arm are connected and installed, the rubber material of the gasket can better fit the outer wall of the arm, reduce gaps in the fit, and avoid instability and shaking caused by gaps after installation.

[0015] In some embodiments, the limiting ring is arranged in an arc shape.

[0016] With the above solution, the arc-shaped limiting ring can better fit the outer wall of the arm body during the docking installation between the installation turntable and the arm body, thus improving the installation stability of the arm body.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By driving the drive equipment, the rotating rod is driven to rotate, which in turn drives the pulley to rotate. The meshing of the two pulleys drives the toothed belt and tooth groove to rotate, and then the tooth groove drives the mounting turntable to rotate, thereby driving the arm body to rotate and swing. The two toothed belts realize the dual-rotation synchronous rotation on both sides, which promotes the practicality of synchronous dual-rotation and reduces the monotony.

[0019] 2. By turning the shaft, the first bevel gear meshes with and drives the second bevel gear to rotate, which in turn drives the screw to rotate, causing the threaded block to move threadedly on the screw surface. This pushes the limiting ring to slide out from the inner wall of the mounting turntable, thus limiting and clamping the outer wall of the arm body to be installed on the mounting turntable. The clamping of the limiting rings on both sides increases the contact area between the mounting turntable and the arm body, improving the stability and firmness of the installation and preventing gaps after installation that could lead to instability and shaking.

[0035] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] This application provides a synchronous belt motor double rotating arm structure. For example... Figures 1-6 As shown, it includes a mounting turntable 1, two mounting turntables 1 with toothed grooves 2 on their outer walls, toothed belts 3 meshing with the surface of the toothed grooves 2, pulleys 4 meshing with the inside of the toothed belts 3, rotating rods 5 being fixedly installed through the bottom ends of the two pulleys 4, and a drive device 6 being fixedly installed at the bottom end of the rotating rods 5.

[0037] By driving the drive device 6, the rotating rod 5 is driven to rotate, which in turn drives the pulley 4 to rotate. The meshing of the two pulleys 4 drives the toothed belt 3 and the toothed groove 2 to rotate. Then, the toothed groove 2 drives the mounting turntable 1 to rotate, thereby driving the arm body 9 to rotate and swing. The two toothed belts 3 achieve double-rotation synchronous rotation on both sides.

[0038] In the technical solution of this application embodiment, the driving device 6 is installed inside the mounting frame 7.

[0039] The mounting frame 7 provides stability for the meshing rotation between the pulley 4 and the toothed belt 3, preventing external forces from affecting the rotation, and also serves as a protective measure.

[0040] In the technical solution of this application embodiment, the mounting frame 7 is connected to the mounting ring 8, and the two mounting rings 8 are movably fitted onto the mounting turntable 1.

[0041] When the tooth groove 2 rotates, it drives the mounting turntable 1 to rotate. The tooth groove 2 rotates inside the mounting ring 8, thereby providing stability for the meshing rotation between the tooth groove 2 and the toothed belt 3 through the mounting ring 8, avoiding external forces from affecting the rotation, and also playing a protective role.

[0042] In the technical solution of this application embodiment, an arm body 9 is installed on the inner wall of two mounting turntables 1, a rotating shaft 10 is movably sleeved on the top of the two mounting turntables 1, a first bevel gear 11 is fixedly installed on one side of the two rotating shafts 10, a second bevel gear 12 is meshed with the surface of the first bevel gear 11, a screw 13 is fixedly installed on one side of the second bevel gear 12, a threaded block 14 is threadedly connected to the outer wall of the screw 13, and a limit ring 15 is fixedly installed on one side of the threaded block 14.

[0043] When the mounting turntable 1 and the arm body 9 are installed together, the first bevel gear 11 is rotated by turning the rotating shaft 10. The first bevel gear 11 meshes with the second bevel gear 12 and drives the screw 13 to rotate. This causes the threaded block 14 to move threadedly on the surface of the screw 13, thereby pushing the limiting ring 15 to slide out from the inner wall of the mounting turntable 1. The outer wall of the arm body 9 installed with the mounting turntable 1 is limited and clamped. The clamping of the limiting rings 15 on both sides increases the contact area between the mounting turntable 1 and the arm body 9, improving the stability and firmness of the installation.

[0044] In the technical solution of this application embodiment, a plurality of gaskets 16 are fixedly embedded in the inner wall of the limiting ring 15.

[0045] When the installation turntable 1 and the arm body 9 are connected and installed, the rubber material of the gasket 16 allows it to fit better against the outer wall of the arm body 9, reducing gaps and preventing instability and shaking after installation.

[0046] In the technical solution of this application embodiment, the limiting ring 15 is arranged in an arc shape.

[0047] By using the arc-shaped limiting ring 15, it can better fit the outer wall of the arm body 9 during the docking installation between the installation turntable 1 and the arm body 9, thereby improving the installation stability of the arm body 9.
