Description

Technical Field

[0001] The invention relates to the technical field of rotating shaft assembly, and in particular to a rotating shaft assembly device. Background Art

[0002] A shaft is an axis used to support and rotate mechanical parts. It is usually a shaft fixed in the structure of a machine, allowing other parts (such as gears, rollers, torque transmission devices, etc.) to rotate around it. The function of a shaft is to support the rotating parts of a mechanical device and transmit force or motion. They are usually made of metal and have sufficient strength and wear resistance to withstand the various stresses and pressures in the mechanical system. Shafts can be found in a variety of devices and mechanical systems, from small household appliances to large industrial machinery. In the fields of automobiles, wind turbines, factory production lines, etc., shafts play a vital role in ensuring the normal operation of mechanical devices.

[0003] When the rotating shaft needs to be supported and rotated at both ends, bearings will be installed at both ends of the rotating shaft respectively, so as to ensure the stability and balance of the rotating shaft and make the load distribution of the rotating shaft at both ends more even. Therefore, the rotating shaft and the bearing need to be assembled together. The existing rotating shaft and bearing assembly is generally performed manually, which is time-consuming, labor-intensive and inefficient. Some assembly equipment is used to assemble the rotating shaft and the bearing, but the existing assembly equipment makes it difficult to align the bearing to the end of the rotating shaft for assembly, which may cause deviation in the assembly position, affecting the normal use of the subsequent rotating shaft. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a rotating shaft assembly device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A rotating shaft assembly device comprises: a workbench, a first movable plate and a second movable plate are respectively vertically arranged on opposite sides of the top of the workbench, a first three-claw chuck and a second three-claw chuck are respectively fixedly installed on the top of the first movable plate and the second movable plate, and a first mounting plate and a second mounting plate are respectively vertically fixedly installed on the top of the first three-claw chuck and the second three-claw chuck;

[0007] A synchronous moving mechanism, the synchronous moving mechanism is used to drive the first moving plate and the second moving plate to move synchronously;

[0008] A first distance sensor, wherein the first distance sensor is fixedly mounted on the inner side of the first mounting plate;

[0009] A distance measuring plate and a second distance sensor, wherein the distance measuring plate and the second distance sensor are located opposite to each other in the vertical direction, and the distance measuring plate and the first distance sensor are located opposite to each other in the horizontal direction;

[0010] The driving mechanism is used to drive the distance measuring plate and the second distance sensor to move.

[0011] The bearing and the rotating shaft are fixed on the first three-claw chuck and the second three-claw chuck respectively. At this time, the front end of the rotating shaft is blocked between the distance measuring plate and the second distance sensor. The driving mechanism is used to drive the distance measuring plate and the second distance sensor to move forward. When the distance sensed by the second distance sensor is equal to the distance between it and the distance measuring plate, it means that the distance measuring plate and the second distance sensor have just exceeded the front end of the rotating shaft. At this time, the movement is stopped immediately. The synchronous moving mechanism is then used to drive the first moving plate and the second moving plate to move synchronously, which drives the distance measuring plate and the first distance sensor to move toward each other, and drives the front end of the rotating shaft and the bearing to approach each other. When the distance sensed by the first distance sensor is 0, it means that the distance measuring plate and the first distance sensor are in contact. At this time, the drive is stopped immediately, and the bearing is just aligned with the front end of the rotating shaft for assembly. There is no need to manually assemble the rotating shaft and the bearing, which saves time and effort and improves work efficiency. The bearing can be directly aligned to the end of the rotating shaft for assembly to ensure the accuracy of the assembly position without affecting the normal use of the subsequent rotating shaft.

[0012] As a further technical solution of the present invention, support legs are vertically welded at the four corners of the bottom of the workbench, bottom wheels are fixedly installed at the bottom of the four support legs, and a connecting rod is horizontally welded in the middle between every two adjacent support legs.

[0013] As a further technical solution of the present invention, the synchronous moving mechanism includes a forward and reverse motor, which is horizontally fixedly installed in the middle of one side of the outer periphery of the workbench. A strip groove is horizontally opened in the middle of the top of the workbench. A screw rod is horizontally connected to the strip groove for horizontal rotation. One end of the screw rod extends out of the strip groove and is fixedly connected to the output shaft of the forward and reverse motor. The first moving plate and the second moving plate are respectively sleeved on the two ends of the screw rod located inside the strip groove. The first moving plate and the second moving plate are both connected to the screw rod through threads, and the threads at the two ends of the screw rod are in opposite directions. The first moving plate and the second moving plate are both slidably connected to the strip groove.

[0014] The forward and reverse motors are started to drive the screw rod to rotate, and due to the effect of the threaded connection, the first moving plate and the second moving plate can be driven to move toward each other on the screw rod.

[0015] As a further technical solution of the present invention, a controller is fixedly installed at one corner of the top of the workbench, and the controller communicates information with all electrical equipment and controls the opening and closing of all electrical equipment.

[0016] As a further technical solution of the present invention, the driving mechanism includes an electric telescopic rod, a lower cross plate is horizontally penetrated and slidably connected on the second movable plate, an upper cross plate is horizontally penetrated and slidably connected on the second mounting plate, the ranging plate is welded to the front end of the upper cross plate, the second distance sensor is fixedly installed at the front end of the top of the lower cross plate, and the same connecting plate is vertically welded between the tail ends of the upper cross plate and the lower cross plate, a through hole is opened on the connecting plate aligned with the center position of the second three-jaw chuck, the electric telescopic rod is horizontally fixedly installed at the bottom of the outer side of the second mounting plate, and the telescopic end of the electric telescopic rod is fixedly connected to the connecting plate.

[0018] The beneficial effects of the present invention are: no manual assembly of the rotating shaft and the bearing is required, which saves time and effort and improves work efficiency; and the bearing can be directly aligned to the end of the rotating shaft for assembly, ensuring the accuracy of the assembly position without affecting the normal use of the subsequent rotating shaft.

[0030] The driving mechanism is used to drive the distance measuring plate 21 and the second distance sensor 19 to move.

[0031] The bearing and the rotating shaft are fixed on the first three-claw chuck 12 and the second three-claw chuck 17 respectively. At this time, the front end of the rotating shaft is blocked between the distance measuring plate 21 and the second distance sensor 19. The driving mechanism is used to drive the distance measuring plate 21 and the second distance sensor 19 to move forward. When the distance sensed by the second distance sensor 19 is equal to the distance between it and the distance measuring plate 21, it means that the distance measuring plate 21 and the second distance sensor 19 have just exceeded the front end of the rotating shaft. At this time, the movement is stopped immediately. Then, the synchronous moving mechanism is used to drive the first moving plate 11 and the second moving plate 18 to move synchronously, and the distance measuring plate 21 and the first distance sensor 14 are driven to move toward each other. When the distance sensed by the first distance sensor 14 is 0, it means that the distance measuring plate 21 and the first distance sensor 14 are in contact. At this time, the driving is stopped immediately, and the bearing is just aligned with the front end of the rotating shaft for assembly. There is no need to manually assemble the rotating shaft and the bearing, which saves time and effort and improves work efficiency.

[0036] The forward and reverse motor 7 is started to drive the screw rod 2 to rotate. Due to the effect of the threaded connection, the first moving plate 11 and the second moving plate 18 can be driven to move toward each other on the screw rod 2.

[0037] Please refer to the attached Figure 3 In a preferred embodiment, a controller 22 is fixedly installed at a corner of the top of the workbench 15. The controller 22 communicates with all electrical equipment and controls the opening and closing of all electrical equipment.

[0038] The distance sensed by the first distance sensor 14 and the second distance sensor 19 is transmitted to the controller 22 in real time. When the distance sensed by the second distance sensor 19 is equal to the distance between it and the distance measuring plate 21, the controller 22 controls the electric telescopic rod 1 to close in real time; when the distance sensed by the first distance sensor 14 is 0, the controller 22 controls the forward and reverse motors 7 to close in real time.

At this time, the front end of the rotating shaft is blocked between the distance measuring plate 21 and the second distance sensor 19, and the electric telescopic rod 1 is started to drive the connecting plate 4 to move toward the second three-claw chuck 17. The connecting plate 4 drives the upper cross plate 3 and the lower cross plate 6 to move, and the upper cross plate 3 and the lower cross plate 6 drive the distance measuring plate 21 and the second distance sensor 19 to move respectively. When the distance sensed by the second distance sensor 19 is equal to the distance between it and the distance measuring plate 21, it means that the distance measuring plate 21 and the second distance sensor 19 have just exceeded the front end of the rotating shaft, and the controller 22 controls the electric telescopic rod 1 to close in real time;

[0044] Restart the forward and reverse motor 7 to drive the screw rod 2 to rotate.

When the distance sensed by the first distance sensor 14 is 0, it means that the distance measuring plate 21 and the first distance sensor 14 are in contact. The controller 22 controls the forward and reverse motor 7 to be turned off in real time. At this time, the bearing is just aligned with the front end of the rotating shaft for assembly. There is no need to manually assemble the rotating shaft and the bearing, which saves time and effort and improves work efficiency. The bearing can be directly aligned with the end of the rotating shaft for assembly to ensure the accuracy of the assembly position without affecting the normal use of the subsequent rotating shaft.
