Description

Technical Field

[0001] This invention relates to the technical field of rotor assembly, specifically to a synchronous clamping mechanism. Background Technology

[0002] The structure of the rotor is shown in the figure. Figure 1 It includes a rotor body 1, a rotating shaft 2, and an upper bearing 3 and a lower bearing 4 respectively fixed at both ends of the rotating shaft. When the rotor is assembled with the gearbox, since different rotors have different lengths and outer diameters, a corresponding rotor clamping mechanism needs to be set up for each model when assembling the rotor and gearbox. In actual assembly, due to the large number of rotor models, different models of rotor clamping mechanisms need to be set up, resulting in high equipment costs. Moreover, the assembly speed of the rotor and gearbox is reduced when different rotor clamping mechanisms are switched during assembly. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a synchronous clamping mechanism that can quickly and reliably clamp different rotors, ensuring efficient assembly of the rotor and gearbox while reducing equipment costs.

[0004] A synchronous clamping mechanism, characterized in that it comprises:

[0005] The frame includes an upper plate, a middle plate, and a lower plate. The upper and lower plates are fixed in position and are combined with connecting rods to form an integral structure. The middle plate is connected to the connecting rods around its perimeter by linear bearings.

[0006] The screw jack assembly includes a driving wheel, a driven wheel, several guide wheels, a transmission belt, and a transmission screw;

[0007] The clamping assembly includes several sets of rotating clamping parts, a drive turntable, and a first drive cylinder. Each set of rotating clamping parts includes a connecting rod, an upper support plate, and a lower pressing plate. When the upper support plate is closed, it supports the lower surface of the upper bearing and centers the entire rotor. When the lower pressing plate is closed, it centers the entire rotor and presses the upper surface of the lower bearing during the pressing process. The upper end of the connecting rod is fixedly supported by an embedded axial spring at the center position of the upper support plate in the length direction. The lower end of the connecting rod is fixedly fitted with the... At the outer end of the pressing flap, each set of upper support flaps includes an inner support flap and an outer drive flap. The outer end of each set of drive flaps is provided with an upwardly protruding drive shaft. The first drive cylinder is fixedly mounted on the lower surface of the middle layer plate. The piston end of the first drive cylinder is pivotally connected to the drive turntable. Several sets of rotating clamping members are arranged in a ring. The upper end of the drive shaft of each set of drive flaps is installed in the corresponding long guide groove of the drive turntable. Each set of connecting rods is respectively positioned in the corresponding positioning holes of the middle layer plate and the lower layer plate through bearings. The pressing flap is arranged in the lower part of the lower layer plate.

[0008] The upper surface of the upper plate is provided with a drive wheel, a driven wheel and several guide wheels. The transmission belt is closedly connected to the drive wheel, the driven wheel and several guide wheels. One of the drive wheel or the driven wheel is provided with a downwardly protruding transmission screw. The lower end of the transmission screw is threadedly engaged with the corresponding screw nut on the middle plate and passes through the downwardly protruding arrangement of the middle plate. The drive wheel is driven to rotate by external power, thereby driving the lifting and lowering of the middle plate.

[0009] Its further features are:

[0010] It also includes an angle adjustment device. The lower inner cavity of the rotating shaft is provided with a keyway structure for meshing gears. The angle adjustment device includes a gripper cylinder, a second drive cylinder, and a pair of gripper arms. The two output ends of the gripper cylinder are respectively connected to the corresponding gripper arms. Each set of gripper arms has at least two sets of circumferential arms. When the pair of gripper arms is in working state, the ends of the circumferential arms are used to hold the corresponding outer shell of the rotor body. The output end of the second drive cylinder is pivotally connected to the gripper cylinder and drives the gripper cylinder to rotate, thereby driving the entire rotor angle to be finely adjusted until the keyway structure and the corresponding gear of the gearbox are reliably inserted and combined.

[0011] It also includes a sensing device, specifically a pair of infrared sensors, including an output end and a receiving end. The output end and the receiving end correspond to the outer diameter area of ​​the rotor body. When the mechanism presses down to assemble the rotor, if the receiving end of the infrared sensor cannot receive a signal within a set time, the angle adjustment device is activated; if the receiving end of the infrared sensor receives a signal within a set time, the angle adjustment device does not need to be activated.

[0012] After adopting the above technical solution, the first driving cylinder drives the drive turntable, so that the rotating clamping component has two states, and the first driving cylinder switches between the two states. In the first initial state, neither the upper support petal nor the lower pressing petal is in a closed state. At this time, it is used to transfer the entire mechanism to the turntable above which it needs to be clamped and transferred. The second state is divided into two situations: clamping and pressing. In the clamping state, the support petal of the upper support petal is in a closed state and is used to support the upper bearing. At this time, the lower pressing petal is in a closed state but does not press down on the rotor. In the pressing state, the upper support petal is in a closed state, and the upper support petal moves along the connection The axial spring of the rod is pressed down, and the lower pressure plate is in a closed state, which is used to hold the lower bearing and thus drive the rotor to press into the corresponding gear of the gearbox. It drives the middle plate to rise and fall through the screw lifting assembly, which in turn drives the support plate of the upper support plate to reliably support the upper bearings of different heights and sizes. After the rotor is transferred to the position and supported at the corresponding gear end of the gearbox, the support plate of the upper support plate is released, and at the same time, the lower pressure plate is driven to center and clamp the lower bearing and press the rotor down. It can quickly and reliably clamp different rotors, ensuring the assembly efficiency of the rotor and gearbox, while reducing equipment costs. Attached Figure Description

When the lower pressing flap 43 is closed, it centers the entire rotor and presses the upper surface of the lower bearing 4 during the pressing process. The upper end of the connecting rod 41 supports the center position of the upper support flap 42 in the longitudinal direction through an embedded axial spring 411. The lower end of the connecting rod 41 is fixedly fitted with the outer end of the lower pressing flap 43. Each set of upper support flaps 42 includes an inner support flap 42. 1.

[0026] The upper surface of the upper plate 11 is provided with a drive wheel 21, two driven wheels 22 and several guide wheels 23. A transmission belt 24 is closedly connected to the drive wheel 21, the two driven wheels 22 and the several guide wheels 23.

The lower end of the transmission screw 25 is respectively connected to the corresponding screw nut 121 on the middle plate 12 through thread engagement. The upper part of the drive wheel 21 is provided with a handwheel structure 70. By rotating the handwheel structure 70, the drive wheel 21 is driven to rotate, thereby driving the middle plate 12 to rise and fall.

[0027] In specific implementation, the entire mechanism also includes an angle adjustment device 80. The lower inner cavity of the rotating shaft 2 is provided with a keyway structure 201 for meshing gears. The angle adjustment device 80 includes a gripper cylinder 81, a second drive cylinder 82, and a pair of gripper arms 83. The two output ends of the gripper cylinder 81 are respectively connected to the corresponding gripper arms 83. Each set of gripper arms 83 has two sets of spaced-apart ring arms 84. Each set of ring arms 84 is provided with a pressure roller 85. When the pair of gripper arms 83 are in working condition, the ring arms... The pressure roller of 84 is used to hold the corresponding outer shell of the rotor body 1. The output end of the second drive cylinder 82 is pivotally connected to the gripper cylinder 81, which drives the gripper cylinder 81 to rotate. The bottom of the gripper cylinder 81 is supported on a partial angle annular guide rail of the base 90 (not shown in the figure), thereby driving the entire rotor angle to be finely adjusted until the keyway structure 201 and the corresponding gear of the lower gearbox are reliably inserted and combined. The second drive cylinder 82 is fixedly mounted on the lower plate, and the bottom of the base 90 is fixedly mounted on the upper surface of the lower plate.

[0028] In specific implementation, the device includes a sensing device, which is a pair of infrared sensors 100, including a transmitting end and a receiving end. The transmitting end and the receiving end correspond to the outer diameter area of ​​the rotor body. The transmitting end and the receiving end are installed in the space between the middle plate 12 and the lower plate 13 by mounting rods. When the mechanism presses down to assemble the rotor, if the receiving end of the infrared sensor 100 cannot receive a signal within a set time, the angle adjustment device 80 is activated; if the receiving end of the infrared sensor 100 receives a signal within a set time, the angle adjustment device does not need to be activated.

[0029] In practice, the fixing ring 53 of the drive turntable 50 is installed on the lower surface of the middle plate 12, and the turntable part 54 of the drive turntable 50 is installed on the lower surface of the fixing ring through the bearing 55 to ensure that the rotation of the turntable part is stable and reliable.

[0031] The center of the middle plate 12 has a clearance hole to ensure that the rotor has enough adjustment space in the height direction.

[0032] Its working principle is as follows: The first drive cylinder drives the drive turntable, causing the rotating clamping component to exist in two states. In the first initial state, neither the upper support petal nor the lower pressing petal is in a closed state. At this time, it is used to transfer the entire mechanism to the turntable above which it needs to be clamped and transferred. The second state is divided into two situations: clamping and pressing. In the clamping state, the support petal of the upper support petal is in a closed state, used to support the upper bearing. At this time, the lower pressing petal is in a closed state but does not press down on the rotor. In the pressing state, the upper support petal is in a closed state and is pressed down along the axial direction of the connecting rod by a spring. The lower pressing petal is in a closed state, used to press down on the lower bearing, thereby driving the rotor to press into the gear. The gearbox has a corresponding gear; it drives the middle plate to rise and fall via a screw lifting assembly, which in turn drives the support petals of the upper support petals to reliably support the upper bearings of different heights and sizes. After the rotor is transferred to the position, the rotor is supported on the corresponding gear end of the gearbox, causing the support petals of the upper support petals to loosen. At the same time, the lower pressure petals are driven to center and clamp the lower bearing and press the rotor down. When the mechanism presses the rotor down for assembly, if the receiving end of the infrared sensor cannot receive a signal within a set time, the angle adjustment device is activated, and the rotor is finely adjusted to complete the press-fit connection. If the receiving end of the infrared sensor receives a signal within a set time, the angle adjustment device does not need to be activated.
