[0026] The structure of the present invention is further described below with reference to the accompanying drawings and by way of examples. It should be noted that the present examples are descriptive rather than restrictive.

[0027] A rotating device for quick adjustment of the buffer base, see Figure 1-Figure 7The buffer base involved includes an upper plate 100, a connecting rod 200, and a bottom plate 300, and the rotating device mainly includes a base 4, a rotating disk 3, a main shaft 1, a tray 2, a first driving transmission mechanism 5 and a second driving transmission mechanism 7.

[0028] The base is cylindrical as a whole, and the rotating disk is relatively rotatably connected to the upper end of the base through a bearing. The lower end surface of the bottom plate of the buffer base is a plane, which contacts the upper plane of the rotating disk to realize the rotation of the bottom plate of the buffer base along the axis.

[0029] The main shaft is arranged concentrically with the base, and the lower end of the main shaft is rotatably supported on a 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 installed and fixedly connected with the tray. The tray and the inner hole of the upper plate of the buffer base form a boss guiding and positioning connection to realize the rotation of the upper plate.

[0030] The main shaft realizes the rotation of the upper plate through the first driving transmission mechanism, and the connecting rod is installed at the specified position point of the bottom plate. Then the assembled parts are placed on the upper end surface of the rotating disk, and the upper plate is placed on the tray to form a rotation trend with the previously installed base parts. The rotating disk is adjusted by the second driving transmission mechanism or the rotation amount of the tray is adjusted by the first driving transmission mechanism to adjust the spatial position of the connecting rod and connect it, thereby realizing the assembly process of rapid installation and adjustment of the buffer base.

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

[0032] The first gear 5.4 is installed near the lower end of the main shaft, and then the first rolling bearing is installed at the lower end of the main shaft, followed by the thrust ball bearing, and then the whole is installed at the position of the bearing seat 6 to form a main shaft component, and then the whole is installed at 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 installed on the first adapter plate 5.2, and the first adapter plate is fixed on the corresponding positioning and mounting surface on the base. The second gear 5.1 is then installed on the rotating shaft of the first motor. The second gear is meshed with the first gear wheel to form an external meshing gear train to realize the rotational drive of the main shaft, the tray and the upper plate of the buffer base.

[0034] By adopting the above-mentioned first driving transmission mechanism, the automatic operation of the rotating device can be realized by controlling the rotation speed of the first motor. The staff only needs to install the upper plate on the pallet, which improves the efficiency of rapid installation and adjustment of the buffer base.

[0035] The control tray is a pair of external meshing gears, the two gears rotate in opposite directions, and the formula for controlling the speed is:

[0036]

[0037] Among them, i 12 Expressed as the transmission ratio of the first gear and the second gear external meshing, n 2 Indicates the speed of the first drive motor, n 1 Expressed as the output speed of the tray, z 2 Expressed as the number of teeth of the second gear, z 1 Expressed as the number of teeth of the first gear, w 1 represents the position angular velocity of the tray, w 2 Indicates the angular velocity of the control motor of the tray.

[0038] The second drive transmission mechanism is composed as follows:

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

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

[0041] The second motor 7.3 is fixedly mounted on the second adapter plate 7.2, the first adapter plate is fixed on the corresponding positioning mounting surface on the base, and then the fourth gear 7.1 is mounted on the rotating shaft of the second motor. The fourth gear passes through the hole of the base and meshes with the third gear teeth 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 the second driving transmission mechanism, the automatic operation of the rotating device can be realized by controlling the rotation speed of the second motor. The staff only needs to install the components of the base on the rotating disk, which improves the efficiency of rapid installation and adjustment of the buffer base.

[0043] The control rotating disk rotates as a pair of internal meshing gears. The two gears rotate in the same direction. The formula for controlling the speed is:

[0044]

[0045] Among them, i 34 Expressed as the transmission ratio of the fourth gear and the third gear, n 3 Indicates the second motor speed, n 4 Expressed as the output speed of the rotating disk, z 4 Expressed as the number of teeth of the fourth gear, z 3 Expressed as the number of teeth of the third gear, w 4 represents the position angular velocity of the rotating disk, w 3 represents the angular velocity of the control motor of the rotating disk 2;

[0046] The two driving transmission mechanisms are controlled by an external control box to control the angular velocity thresholds of the two motors;

[0047] The angular velocity threshold is used to monitor the rotation of rotating parts. If the 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 is set, and the angular velocity threshold is used to ensure that the motor runs within the predetermined speed range. If the angular velocity of the motor exceeds or falls below the set threshold, the control system will adjust the input signal of the motor to maintain a stable operating state;

[0049] The control box 10 stores a control program and a cut-off program. The calculation formula involved in the control program is:

[0050]

[0051] Among them, w H represents the relative angular velocity of the rotating disk and the tray, w 1 represents the position angular velocity of the tray, w 4 represents the angular velocity of the rotating disk position, n 1 It is expressed as the speed of the first motor controlling the tray, n 2 It is expressed as the speed of the second motor that controls the rotating disk, z 1 Expressed as the number of teeth of the first gear, z 2 Expressed as the number of teeth of the second gear, z 3 Expressed as the number of teeth of the fourth gear, z 4 Expressed as the number of teeth of the third gear.

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

Positioning mounting tables are provided in the two motor mounting holes, respectively, and are marked as 4.5 and 4.8 in the attached drawings, so as to realize the fixing of 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 plane groove 4.7 is provided on the bottom of the base to install a dustproof bottom plate 11 to achieve dustproof protection for the motor and the gear transmission mechanism.

[0056] The rotating disk is provided with a center hole 3.1, which serves as a positioning guide for the installation of the rotating disk and is used to form a clearance guide fit with the rotating disk guide section of the main shaft.
