Description

Technical Field

[0001] This utility model relates to the field of bushing technology, and in particular to an automatic lifting and rotating mechanism for a clamping platform. Background Technology

[0002] A clamping table can firmly hold a workpiece, keeping it in a stable position during machining, assembly, and measurement operations, preventing movement and shaking from affecting machining accuracy and operational precision. For example, when drilling holes in mechanical parts, the clamping table fixes the parts to ensure precise drilling positions; when assembling electronic components, it fixes the circuit board to facilitate accurate component installation.

[0003] However, when using the existing automatic lifting and rotating mechanism for clamping tables, the clamping table is rotated by a motor to adjust the angle and meet different assembly needs. However, the items held by the clamping table have a certain weight, which can easily cause an imbalance on one side, and the overall rotation is inconvenient. Therefore, an automatic lifting and rotating mechanism for clamping tables is needed. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic lifting and rotating mechanism for a clamping platform, which solves the problems of uneven force distribution, easy tilting, and inconvenient overall rotation of the clamping platform in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic lifting and rotating mechanism for a clamping platform, comprising a column connected to a fixed platform, a main crossbeam fitted on the outer wall of the column, rotating shafts on both sides of the main crossbeam, a driven gear and a connecting arm fitted on the outer wall of the rotating shaft, a clamping platform assembly connected to one end of the connecting arm, a driving gear meshing with the outer wall of the driven gear, and a motor reducer assembly connected to the side wall of the main crossbeam.

[0006] Preferably, a cylindrical ball bearing and a thrust ball bearing are provided between the column and the main crossbeam.

[0007] Preferably, the top of the main beam is connected to a top cover fitted onto the outer wall of the column, the top of the column is connected to a mounting plate, a cylinder is mounted on the top surface of the mounting plate, and the output end of the cylinder passes through the mounting plate and is connected to a positioning pin.

[0008] Preferably, the top cover has holes adapted to the column, and the top cover has a groove that matches the positioning pin.

[0009] Preferably, there are two sets of cylindrical ball bearings and thrust ball bearings, which are symmetrically distributed about the central axis of the main beam.

[0010] Preferably, one side of the clamp assembly is provided with a connecting arm extending toward the driven gear, and the driven gear is located inside the connecting arm and sleeved on the outer wall of the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The drive gear rotates through the motor reducer assembly on both sides, which in turn drives the driven gear to rotate the connecting arm and clamp platform assembly up and down, thus raising or lowering the clamp platform assembly. When the clamp platform assembly is raised, the cylinder pulls out the positioning pin, which can push the clamp platform assembly to rotate 90°. The cylinder then pushes the positioning pin forward, positioning the clamp platform assembly. Attached Figure Description

[0017] 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.

[0018] This utility model relates to an automatic lifting and rotating mechanism for a clamping platform, such as... Figure 1-3As shown, the system includes a column 1, which is mounted on a fixed platform to support the entire equipment. A main crossbeam 2 is installed on the outer wall of the column 1. A cylindrical ball bearing 3 and a thrust ball bearing 4 are provided between the main crossbeam 2 and the column 1. The cylindrical ball bearing 3 and the thrust ball bearing 4 enable the main crossbeam 2 to rotate around the outer wall of the column 1. There are two sets of cylindrical ball bearings 3 and thrust ball bearings 4, which are symmetrically distributed about the central axis of the main crossbeam 2 to ensure smooth rotation.

[0019] Furthermore, a rotating shaft 5 is installed at the end of the main crossbeam 2. The rotating shaft 5 is inserted into the interior of the main crossbeam 2 and rotatably connected. An oilless bearing 6 is provided at the connection between the rotating shaft 5 and the main crossbeam 2 to ensure that the rotating shaft 5 can rotate. A connecting arm 7 is fixedly connected to the outer wall of the rotating shaft 5. The driven gear 8 is located on the outside of the connecting arm 7. The rotation of the driven gear 8 drives the rotating shaft 5 to rotate, thereby realizing the adjustment of the position of the connecting arm 7. A second gear cover 9 is provided on the side of the driven gear 8 away from the main crossbeam 2. The second gear cover 9 serves as a dustproof protection.

[0020] Furthermore, a motor reducer assembly 10 is fixedly connected to the side wall of the main crossbeam 2. The output end of the motor reducer assembly 10 is fixedly connected to the inner wall of the drive gear 11. A first gear cover 18 is installed on the outside of the drive gear 11. The first gear cover 18 and the second gear cover 9 serve the same protective function. A driven gear 8 is meshed with the outer wall of the drive gear 11. The motor reducer assembly 10 drives the drive gear 11 to rotate, causing the driven gear 8 to rotate, thereby adjusting the position of the connecting arm 7 and the clamp platform assembly 12. The end of the connecting arm 7 is fixedly connected to the clamp platform assembly 12, enabling the connecting arm 7 and the clamp platform assembly 12 to rotate around the axis of the main crossbeam 2.

[0021] Among them, such as Figure 3 As shown, there are two sets of motor reducer assemblies 10, which are symmetrically distributed about the side wall of the main crossbeam 2 to stabilize the rotation direction of the driven gear 8 and improve the balance of the workpiece.

[0022] Furthermore, a top cover 13 is fixedly connected to the top center of the main beam 2. The top cover 13 is fitted onto the outer wall of the column 1. The top cover 13 has holes that match the column 1. The top of the column 1 is fixedly connected to the mounting plate 15 by a locking nut 14. Tightening the locking nut 14 locks the mounting plate 15 to the top of the column 1. A cylinder 16 is installed on the top surface of the mounting plate 15. The output end of the cylinder 16 passes through the mounting plate 15 and is fixedly connected to the positioning pin 17. The top cover 13 has a slot that matches the positioning pin 17. The cylinder 16 drives the positioning pin 17 to insert into or disengage from the slot of the top cover 13. When the positioning pin 17 disengages from the slot, it can adjust the position of the main beam 2, so that the main beam 2 rotates around the axis of the column 1.

[0023] In practical use: the operation of the motor reducer assembly 10 on both sides causes the drive gear 11 to rotate, which drives the driven gear 8 to rotate the connecting arm 7 and the clamp platform assembly 12 up and down, thereby raising or lowering the clamp platform assembly 12. When the clamp platform assembly 12 is raised, the cylinder 16 pulls out the positioning pin 17, which can push the clamp platform assembly 12 to rotate 90°. The cylinder 16 pushes the positioning pin 17 to position the clamp platform assembly 12.
