DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 8As shown, the present invention provides an explosion-proof motor assembly device, including a workbench 1, a square hole 11 is opened on the workbench 1, a limit seat 4 is fixedly connected to the upper end of the workbench 1 located at the rear side of the square hole 11, and a mounting seat 5 is fixedly connected to the upper end of the workbench 1 located at the front side of the square hole 11, and a fixing mechanism 7 and a pushing installation mechanism 6 are arranged inside the mounting seat 5. The limit seat 4 cooperates with the pushing mechanism and the fixing mechanism 7 to realize the installation of the bearing on the rotor shaft. A conveying mechanism 2 and a pushing mechanism 3 are arranged inside the workbench 1. The conveying mechanism 2 and the pushing mechanism 3 cooperate with each other to move the rotor shaft without the bearing installed to the lower end of the limit seat 4 for processing; during operation, through With the cooperation of the conveying mechanism 2 and the pushing mechanism 3, the rotor shaft without the bearing installed is moved to the front end of the limit seat 4. At this time, the fixing mechanism 7 and the pushing installation mechanism 6 are cooperated to connect the bearing to the rotor shaft without the bearing installed, so as to achieve the effect of assembling the rotor. The installed rotor shaft is moved to the top of the conveying mechanism 2 again through the pushing mechanism 3, and the conveying mechanism 2 is cooperated to continue the bearing installation of the next rotor shaft without the bearing installed. The bearing is installed on the rotor shaft through mechanization, thereby solving the problem that the manual assembly of bearings and rotor shafts is inefficient in large-scale production, and the bearing may be unevenly stressed during the knocking process, which increases the difficulty of assembling the rotor shaft and the bearing.

[0032] In a further embodiment, referring to Figure 2 The conveying mechanism 2 includes a conveying frame 21 and a supporting seat. The conveying frame 21 is fixedly connected inside the workbench 1. Two groups of conveying frames 21 are provided and are located on the front and rear sides of the workbench 1. The left and right sides between the two groups of conveying frames 21 are rotatably connected with a rotating shaft 22. The front and rear side walls of the rotating shaft 22 are fixedly connected with synchronous wheels 23. The two groups of synchronous wheels 23 are connected through a synchronous belt 24. The outer wall of the synchronous belt 24 located on the front side of the rotating shaft 22 is equidistantly fixedly connected with a supporting seat 26. The outer wall of the synchronous belt 24 located on the rear side of the rotating shaft 22 is equidistantly fixedly connected with a limiting rod 25. The front end of the left side of the conveying frame 21 is fixedly connected with a first motor 27, and the output shaft end of the first motor 27 is fixedly connected to the front end of the rotating shaft 22.

[0033] In this embodiment, when the first motor 27 is started, it will drive the rotating shaft 22 to rotate, and the rotation of the rotating shaft 22 will drive the synchronous wheel 23 to rotate together. Since the two sets of synchronous wheels 23 are interconnected by the synchronous belt 24, they will synchronously drive the support seat 26 and the limit rod 25 to move together; this movement further causes the rotor shaft placed on the support seat 26 and the limit rod 25 to move accordingly, accurately positioning the rotor shaft just above the pushing mechanism 3; such a layout allows the rotor shaft to be easily pushed to the front end of the limit seat 4 by the pushing mechanism 3, preparing for the subsequent bearing installation.

[0034] In a further embodiment, referring to Figure 3-Figure 4The pushing mechanism 3 includes a multi-stage hydraulic cylinder 31 and a lifting seat 32. The multi-stage hydraulic cylinder 31 is fixedly connected inside the workbench 1. The output shaft end of the multi-stage hydraulic cylinder 31 is fixedly connected to the lifting seat 32. An arc groove 321 is opened on the upper end surface of the lifting seat 32. A limiting block 33 is fixedly connected to the rear side of the arc groove 321. The lifting seat 32 is located between the two groups of conveying frames 21 and is located in the positive direction of the square hole 11. The limiting seat 4 includes a fixed block 41 and a stop block 42. The working upper end located at the rear side of the square hole 11 is fixedly connected to the fixed block 41. The front end of the fixed block 41 is fixedly connected to the stop block 42 and the arc plate 43. The arc plate 43 is located directly above the stop block 42.

[0035] In this embodiment, the lifting seat 32 is driven to move upward by starting the multi-stage hydraulic cylinder 31. The lifting seat 32 moving upward will abut against the rotor shaft and drive the rotor shaft to move upward. When the lifting seat 32 passes through the square hole 11, the side wall of the rotor shaft is convenient for abutting against the arc plate 43, thereby preliminarily fixing the rotor shaft. When the bearing is assembled, the pressure transmitted by the bearing drives the rotor shaft to move backward. At this time, the rear end of the rotor shaft abuts against the abutment 42, so that the rotor shaft will not tilt during assembly, thereby solving the problem that uneven force on the bearing may be caused during the knocking process, which increases the difficulty of assembling the rotor shaft and the bearing.

[0036] In a further embodiment, referring to Figure 5 A seat 51 to be rotated is fixedly connected inside the mounting seat 5, a guide groove 52 is provided on the upper end surface of the right side of the mounting seat 5, a loading rack 53 is fixedly connected to the right end of the mounting seat 5, and the loading rack 53, the guide groove 52 and the seat 51 to be rotated are interconnected.

[0037] In this embodiment, by placing the bearing on the loading rack 53, since the right end of the loading rack 53 is higher than the left end, the bearing rolls onto the seat to be rotated 51 through the guide groove 52 due to the effect of gravity, which facilitates the subsequent fixation of the bearing.

[0038] In a further embodiment, referring to Figure 7-Figure 8 The fixing mechanism 7 includes a mounting frame 71 and a clamping plate 73. The mounting seat 5 is slidably connected with the mounting frame 71 inside. The mounting frame 71 is located at the rear end of the seat to be rotated 51 and abuts against it. The left and right ends inside the mounting frame 71 are rotatably connected with the bidirectional threaded rod 72. The upper and lower side walls between the two groups of bidirectional threaded rods 72 are threadedly connected with the clamping plate 73. The two groups of bidirectional threaded rods 72 are connected by a sprocket transmission assembly 74. The upper end of the mounting frame 71 is fixedly connected with a second motor 75. The output shaft end of the second motor 75 is fixedly connected to the upper end of the bidirectional threaded rod 72. The front ends of the left and right sides of the seat to be rotated 51 are fixedly connected with the fixing sleeve 54. The fixing sleeve 54 is fixedly connected with a spring 55 inside. The rear end of the spring 55 is fixedly connected to the front end of the mounting frame 71.

[0039] The second motor 75 is started to drive the two-way threaded rod 72 to rotate. Since the two sets of two-way threaded rods 72 are connected by the sprocket transmission assembly 74, the two sets of two-way threaded rods 72 are driven to rotate at the same time. The rotation of the two-way threaded rod 72 drives the clamping plate 73 to move closer to the middle, thereby clamping and fixing the bearing. At the same time, the movement of the bearing makes the axis of the bearing coincide with the axis of the rotor shaft, which is convenient for the subsequent installation of the bearing. By setting the spring 55, when the mounting frame 71 moves to the rear side of the mounting seat 5, the spring 55 will be stretched. After the bearing is installed, the second motor 75 can be started to drive the two-way threaded rod 72 to rotate in the opposite direction, so that the clamping plate 73 cancels the clamping of the bearing. At this time, the mounting frame 71 is driven to move by the recovery deformation of the spring 55, so that the mounting frame 71 is moved to the initial position, which is convenient for the assembly of the bearing of the next group of rotor shafts.

[0040] In a further embodiment, referring to Figure 5-Figure 6 The pushing installation mechanism 6 includes a first hydraulic cylinder 61 and a pushing plate 62. The front end of the mounting seat 5 is fixedly connected to the first hydraulic cylinder 61 through a fixed seat 64. The output shaft end of the first hydraulic cylinder 61 is fixedly connected to the pushing plate 62. A reserved hole 621 is provided on the front end surface of the pushing plate 62. The left and right ends of the pushing plate 62 are fixedly connected to connecting blocks 63. The connecting block 63 cooperates with the front end surface of the mounting frame 71. A limiting mechanism 8 is also arranged inside the mounting seat 5. The limiting mechanism 8 includes a second hydraulic cylinder 81 and a limiting plate 82. The second hydraulic cylinder 81 is fixedly connected inside the workbench 1. The output shaft end of the second hydraulic cylinder 81 is fixedly connected to the limiting plate 82. The limiting plate 82 is located at the rear end of the mounting frame 71 and abuts against it.

[0041] In this embodiment, in the process of moving the upper end bearing of the swivel seat 51 to the clamping plate 73, the second hydraulic cylinder 81 is first started to drive the limit plate 82 to move upward, so that the limit plate 82 moves the rear end of the mounting frame 71, and then the first hydraulic cylinder 61 is started to drive the push plate 62 to move. The push plate 62 moving backward will drive the bearing to move to the clamping plate 73, and through the limitation of the limit plate 82, the excessive movement of the bearing is avoided. When the bearing moves into the clamping plate 73, the second motor 75 in the mounting frame 71 will be started to clamp the bearing; when the bearing is clamped by the clamping plate 73, the second motor 75 in the mounting frame 71 will be started. After that, the second hydraulic cylinder 81 is started to drive the limit plate 82 to move downward, and then the first hydraulic cylinder 61 is started to drive the push plate 62 to move backward. The push plate 62 moves backward and drives the connecting block 63 to move backward. The connecting block 63 that moves backward abuts against the mounting frame 71 and drives the mounting frame 71 to move backward, thereby driving the bearing to move backward. Since the inner diameter of the reserved hole 621 provided on the push plate 62 is larger than the inner diameter of the bearing, when the bearing is sleeved on the rotor shaft, the front end of the rotor shaft passes through the reserved hole 621 to the front end of the push plate 62, thereby realizing the assembly of the bearing.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
