Technical Field

[0001] This invention belongs to the field of buffer base installation technology, and particularly relates to a rotating device for quick assembly and adjustment of buffer bases. Background Technology

[0002] The buffer base is a large base composed of multiple parallel connecting rods. Its complex structure and difficult assembly require the cooperation of several skilled workers. The existing assembly process is as follows: first, multiple connecting rods 200 are assembled onto the base plate 300; then, the upper plate 100 is lifted and its relative position is aligned; finally, the upper ends of the multiple connecting rods are connected to the upper plate to complete the assembly.

The current assembly method suffers from low efficiency, low safety, and high assembly and adjustment costs. To change this situation and optimize the assembly process, a dedicated rotating device for the assembly and adjustment of the buffer base is pre-designed to improve assembly efficiency, increase safety, improve product quality, and reduce costs. Summary of the Invention

The diameter of the tray mounting section is the same as the inner diameter of the tray, and the diameter of the upper transition connection section is larger than the diameter of the tray mounting section, forming a tray support surface between the two. The outer diameters of the rotating disk guide section, the lower transition connection section, the gear mounting section, the rolling bearing mounting section, and the thrust bearing mounting section decrease sequentially.

[0010] Furthermore, a bearing mounting groove is provided on the lower part of the rotating disk around the central hole, and the bearing mounting groove of the rotating disk is aligned with the bearing mounting groove on the top of the base, so that the bearings of the rotating disk and the top of the base can be embedded; and a gear mounting groove is provided on the lower part of the rotating disk around the bearing mounting groove.

[0011] Moreover, the first drive transmission mechanism includes a first motor, a first gear, a second gear, and a first adapter plate; the first motor is disposed in a first motor mounting hole on the base, the first motor is fixed on the first adapter plate, the first adapter plate is fixed at the positioning mounting platform in the first motor mounting hole, the second gear is fixed on the output shaft of the first motor, the first gear is fixed on the gear mounting section of the main shaft, and the first gear and the second gear mesh.

[0026] The structure of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that these embodiments are descriptive and not limiting.

[0027] A rotating device for quick assembly and adjustment of a buffer base; please refer to [link / reference]. Figures 1-7The buffer base involved includes an upper plate 100, a connecting rod 200, and a bottom plate 300. The rotating device mainly includes a base 4, a rotating disk 3, a main shaft 1, a tray 2, a first drive transmission mechanism 5, and a second drive transmission mechanism 7.

[0028] The base is cylindrical in shape. The rotating disk is rotatably connected to the upper end of the base via bearings. The lower end surface of the bottom plate of the buffer base is flat and contacts the upper surface of the rotating disk, thereby enabling the bottom plate of the buffer base to rotate along the axis.

[0029] The main shaft is concentrically arranged with the base. The lower end of the main shaft is rotatably supported on the bearing seat 6 fixed at the lower end of the base. The upper end of the main shaft extends to the top of the base and is coaxially connected with the tray. The tray and the inner hole of the upper plate of the buffer base form a boss for guiding and positioning connection, so as to realize the rotation of the upper plate.

[0030] The main shaft rotates the upper plate through the first drive transmission mechanism, and the connecting rod is installed at the designated position point on the base plate. Then, the assembled components are placed on the upper surface of the rotating disk, and the upper plate is placed on the tray, forming a rotation trend with the previously assembled base components. The spatial position of the connecting rod is adjusted and connected by adjusting the rotation of the rotating disk through the second drive transmission mechanism or by adjusting the rotation of the tray through the first drive transmission mechanism, thus realizing the assembly process of rapid assembly and adjustment of the buffer base.

[0031] The specific structure of the first drive transmission mechanism is as follows:

[0032] The first gear 5.4 is installed near the lower end of the main shaft. Then, the first rolling bearing is installed at the lower end of the main shaft. Next, the thrust ball bearing is installed and then the whole assembly is installed in the bearing housing 6 to form the main shaft component. Finally, the whole assembly is installed in the lower end of the base. The first rolling bearing 9 and the thrust ball bearing 10 form a free three-dimensional fit to realize the free rotation of the main shaft.

[0033] The first motor 5.3 is mounted on the first adapter plate 5.2, which is fixed on the corresponding positioning mounting surface on the base. The second gear 5.1 is then mounted on the rotating shaft of the first motor. The second gear meshes with the first gear to form an external meshing gear train, thereby realizing the rotational drive of the main shaft, tray, and buffer base plate.

[0034] By adopting the first drive transmission mechanism described above, the rotational device can be automated by controlling the speed of the first motor. The operator only needs to install the upper plate on the tray, which improves the efficiency of quick assembly and adjustment of the buffer base.

[0035] The rotation of the tray is controlled by a pair of meshing gears, with the two gears rotating in opposite directions. The formula for controlling the rotational speed is:

[0036]

[0037] Among them, i 12 The transmission ratio of the external meshing of the first gear and the second gear is represented by n2, the speed of the first drive motor is represented by n1, the output speed of the tray is represented by z2, the number of teeth of the second gear is represented by z1, the number of teeth of the first gear is represented by w1, the position angular velocity of the tray is represented by w2, and the control motor of the tray is represented by w2.

[0038] The second drive transmission mechanism is composed of the following:

[0039] The second rolling bearing 8 is placed at a designated position on the base and the rotating disk to support the rotating disk;

[0040] The third gear 7.4 is an internal gear ring structure. The third gear is coaxially mounted on the rotating disk and connected and fixed.

[0041] The second motor 7.3 is fixedly installed on the second adapter plate 7.2. The first adapter plate is fixed on the corresponding positioning and mounting surface on the base. The fourth gear 7.1 is then installed on the rotating shaft of the second motor. The fourth gear passes through the hole in the base and meshes with the teeth of the third gear to form an internal meshing gear train, thereby realizing the rotation drive of the rotating disk and the lower plate of the buffer base.

[0042] By adopting this second drive transmission mechanism, the rotating device can be automated by controlling the speed of the second motor. The operator only needs to install the components of the base onto the rotating disk, which improves the efficiency of quick assembly and adjustment of the buffer base.

[0043] The rotation of the rotating disk is controlled by a pair of internal meshing gears, both gears rotating in the same direction. The formula for controlling the rotational speed is:

[0044]

[0045] Among them, i 34 The transmission ratio of the internal meshing of the fourth and third gears is represented by n3, the speed of the second motor is represented by n4, the output speed of the rotating disk is represented by z4, the number of teeth of the fourth gear is represented by z3, the number of teeth of the third gear is represented by w4, the position angular velocity of the rotating disk is represented by w3, and the angular velocity of the control motor of the rotating disk is represented by w4.

[0046] The two drive transmission mechanisms mentioned above are controlled by an externally installed control box, which controls the angular velocity thresholds of the two motors.

[0047] The angular velocity threshold is used to monitor the rotation of rotating parts. If the rotation speed exceeds the set threshold, it will cause mechanical failure or danger, and the control system will issue an alarm or automatically slow down.

[0048] In the control system, the motor speed and angular velocity threshold are set to ensure that the motor operates within a predetermined speed range. If the motor's angular velocity exceeds or falls below the set threshold, the control system will adjust the motor's input signal to maintain a stable operating state.

[0049] The control box 10 stores control and shutdown programs. The calculation formulas involved in the control program are as follows:

[0050]

[0051] Among them, w H The relative position angular velocities of the rotating disk and the tray are represented by w1, w4, n1, and z1. The number of teeth on the first gear is represented by z1, z2, z3, and z4.

[0052] The control system adopts a simple and intuitive operating interface or operating structure, enabling operators to easily perform assembly and adjustment operations without the need for complex tools and professional skills; it adopts an automatic control system to achieve automatic positioning, improving the speed and accuracy of assembly and adjustment.

[0053] The specific structural form of the aforementioned base is as follows:

[0054] The base has a central hole 4.1, which is a through hole for mounting the main shaft. A bearing housing mounting surface 4.6 is located at the lower end of the central hole for fixing the bearing housing. An annular groove 4.3 is located on the top of the base around the central hole for mounting the first rolling bearing. A first motor mounting hole and a second motor mounting hole are respectively located on either side of the central hole on the base. These two motor mounting holes intersect and communicate with the central hole, for mounting two motors respectively. The first motor mounting hole is a blind hole that does not communicate with the upper end of the base. A through hole 4.4 extending to the top surface of the base is coaxially located at the upper end of the second motor mounting hole, enabling the connection between the fourth gear located above the base and the second motor's main shaft. Positioning mounting surfaces, labeled 4.5 and 4.8 in the attached drawings, are provided in the two motor mounting holes respectively, for fixing the corresponding motor mounting plates. In addition, a process groove 4.2 is provided on the top of the base to reduce end-plane friction, and a flat groove 4.7 is provided on the bottom of the base to install a dustproof base plate 11, thereby achieving dustproof protection for the motor and gear transmission mechanism.

[0055] The main shaft is composed of a tray mounting section 1.1, an upper transition connection section 1.2, a rotating disk guide section 1.3, a lower transition connection section 1.4, a gear mounting section 1.5, a rolling bearing mounting section 1.6, and a thrust bearing mounting section 1.7 connected sequentially from top to bottom. The diameter of the tray mounting section is the same as the inner diameter of the tray, while the diameter of the upper transition connection section is larger than that of the tray mounting section, forming a tray support surface between them. The outer diameter of the rotating disk guide section is slightly smaller than the diameter of the center hole of the base, allowing the main shaft to be installed in the center hole of the base with a clearance fit. The outer diameters of the rotating disk guide section, the lower transition connection section, the gear mounting section, the rolling bearing mounting section, and the thrust bearing mounting section decrease sequentially. The gear mounting section is used to fix and install the first gear, while the rolling bearing mounting section and the thrust bearing mounting section respectively install the first rolling bearing and the thrust ball bearing.

[0056] The rotating disk has a central hole 3.1, which serves as a positioning guide for the rotating disk during installation and forms a clearance guide fit with the rotating disk guide section of the main shaft. A bearing mounting groove 3.3 is provided at the lower part of the rotating disk, aligning with the bearing mounting groove at the top of the base to install the first rolling bearing. A gear mounting groove 3.2 is provided at the lower part, around the bearing mounting groove, for embedding and fixing the third gear.

[0057] Based on the above-mentioned method of using the rotating device for quick assembly and adjustment of the buffer base, the specific steps are as follows:

[0058] 1. Install the base plate with the connecting rod on top of the rotating disk of the rotating device;

[0059] 2. Install the top plate on top of the pallet;

[0060] 3. Turn on the power to the control box and set the motor speed and the relative position of the rotating disc and tray on the control box display screen;

[0061] 4. Click the start button on the display screen. The rotating device will work to achieve the relative rotation of the base plate and the upper plate, connecting the upper end of the connecting rod to the designated position of the upper plate, and completing the assembly of the buffer base.

[0062] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
