[0002] At present, the existing motor assembly equipment has a relatively simple functional structure and cannot complete a series of operations such as inserting the rotor, pressing the end cover, pressing the bearing, etc. on one device. The motor cannot be directly hoisted onto the equipment, and the existing equipment does not have the function of rotating and lifting the mounting plate, which is not convenient for inserting the rotor and tightening the end cover screws. Therefore, it is necessary to improve the existing equipment to solve the shortcomings of the existing technology. Summary of the invention

[0028] In order to realize the installation structure of the floating top 603, the piston rod in the press-fitting oil cylinder 601 is a hollow piston rod, the press-fitting oil cylinder 601 is connected to the hydraulic pump station 2 through an oil pipe, and the installation handle of the floating top 603 is slidably arranged in the middle hole of the piston rod. The installation structure of the floating top 603 is effectively realized, with a simple structure and good stability.

[0029] In order to effectively realize rotation, lifting and horizontal fine adjustment, the rotating lifting mechanism includes a lifting mechanism, a rotating mechanism and a horizontal fine adjustment mechanism, the horizontal fine adjustment mechanism is arranged on the rotating mechanism, the rotating mechanism is arranged on the lifting mechanism, and the lifting mechanism is arranged on the base 701. It can effectively realize rotation, lifting and horizontal fine adjustment, and realize the lateral movement of the entire rotating lifting mechanism relying on the base 701.

[0030] In order to realize a height-controllable lifting mechanism, the lifting mechanism includes a horizontal lifting plate 702, a vertical lifting motor 703 arranged at the right side of the lifting plate 702, a driving pulley 704 arranged at the shaft output at the upper end of the lifting motor 703, and a vertical displacement sensor 705 connected between the lifting plate 702 and the base 701.

The rotation of the rotating plate 711 is realized by the drive of the reduction motor 710 and the gear transmission, and the operating surface can be easily rotated to the side of the operator, which is convenient for the installation of parts.

[0032] In order to achieve fine adjustment of the motor position, the horizontal fine adjustment mechanism includes a horizontal motor placement plate 714, a universal ball table 715 and side ribs 716. The universal ball table 715 is connected and fixed on the top of the rotating plate 711, the motor placement plate 714 is placed on the universal ball table 715, and the side ribs 716 are connected and fixed on the top of the rotating plate 711 and distributed around the motor placement plate 714. Each side rib 716 is against the side of the motor placement plate 714 through an adjustment screw 717. The motor placement plate 714 can slide horizontally on the universal ball table 715, and can be adjusted in the left and right and front and back directions through the adjustment screw 717 to achieve fine adjustment of the motor position, which is used to compensate for the error of the anchor hole of the motor itself.

[0033] In order to realize the positioning and assembly of various motors, the motor placement plate 714 is provided with positioning pins 718 holes corresponding to the anchor holes of various motors to be assembled, and the positioning pins 718 holes are provided with pluggable positioning pins 718 for directly fixing the motors. The positioning and installation of various motors can be effectively realized.

[0034] In order to realize the lateral sliding of the rotary lifting mechanism, two groups of lateral linear guide rails 8 are provided on the front and rear sides of the middle of the equipment platform 3 in the lateral direction, and the base 701 is slidably arranged on the linear guide rails 8 through the sliding connection 10; the hydraulic horizontal sliding mechanism includes two lateral horizontal sliding oil cylinders 9 arranged on the left and right sides of the base 701, and the left and right sides of the lower end surface of the base 701 are provided with oil cylinder sliding frames 719, and the output shaft of the horizontal sliding oil cylinder 9 is extended and pressed against the oil cylinder sliding frame 719 to push the base 701 to move horizontally, and the cylinder body of the horizontal sliding oil cylinder 9 is connected and fixed to the equipment platform 3. The base 701 can be pushed conveniently, and during the pressing process, the output shaft of the horizontal sliding oil cylinder 9 is retracted and separated from the contact with the oil cylinder sliding frame 719, so that in the pressing direction, the motor is in a lateral floating state, ensuring that the end caps or bearings at both ends can be pressed into place at the same time.

[0035] In order to facilitate the operation of the operator, the hydraulic pump station 2 is arranged on the left side of the rear side of the equipment platform 3. The hydraulic pump is arranged on the non-operating side to facilitate the operation of the operator.

[0036] In order to prevent the end cover from being crushed, the hydraulic pump station 2 is provided with a hydraulic proportional valve, which is connected to the control device 1. The pressing force can be easily adjusted, and the end cover can be prevented from being crushed by pressure adjustment.

[0037] During operation, the operator switches to the corresponding motor type through the control device 1, lifts the motor placement plate 714 to the corresponding height, so that the height difference between the center position of the hydraulic pressing mechanism 6 and the motor placement plate 714 basically meets the motor installation requirements, hoists the motor into place, controls the rotating mechanism through the control device 1, and rotates the motor 90 degrees in the horizontal direction, with the front end of the motor base facing the operator. The operator inserts the motor rotor, and then installs the front end bearing inner cover and end cover. After the installation is completed, the threaded through holes of the end cover and the threaded holes of the motor base are pre-tightened with bolts. After completion, press the rotation button of the control device 1, and the motor rotates 180 degrees so that the rear end faces the operator, and the rear end bearing inner cover and end cover are installed. After the installation is completed, similarly, the threaded through holes of the end cover and the threaded holes of the base are pre-tightened with bolts. After completion, rotate it 90° again so that the motor shaft direction is horizontal with the pressing direction.

[0038] The operator switches the equipment to the function of pressing the end cover through the control device 1, and controls the pressing force to a relatively small value through the proportional valve, so that the pressure can press the end cover into place without damaging the end cover. When pressing the end cover, the output shaft of the horizontal push cylinder 9 retreats and breaks away from the contact with the base 701, so that the base 701 can slide laterally, and then the height of the motor placement plate 714 is adjusted by adjusting the lifting mechanism so that the floating center 603 is completely aligned with the center hole of the motor shaft. Press the confirmation button on the control device 1 to complete the alignment, and the workbench automatically drops 1mm to make up for the air gap between the rotor and the stator. Then, under the control of the control device 1, the two pressing cylinders 601 on the left and right sides of the motor end cover of the hydraulic pressing mechanism 6 start to press the end cover synchronously. After pressing into place, the hydraulic pressing mechanism 6 retreats.

[0039] The rotating mechanism rotates 90 degrees, and the front end of the motor faces the operator. The control device 1 is used to control the locking assembly workbench 7 so that it cannot move and rotate. The operator tightens the end cover bolts into place with a pneumatic tightening gun and installs the bearing. The rotating mechanism rotates 180°, and the rear end of the motor faces the operator. Similarly, the operator tightens the bolts into place and installs the bearing. The rotating mechanism rotates 90°, and the motor turns to be horizontal with the motor shaft and the pressing direction. The control device 1 switches to the bearing pressing function, and the shaft output of the horizontal push cylinder 9 retracts and disengages from the contact with the base 701, so that the base 701 is in a sliding state. The control device 1 controls the pressing force to a relatively large value through the proportional valve, and the hydraulic horizontal push mechanism aligns the motor shaft and presses the bearing into place. After reaching the set pressure value, the hydraulic horizontal push mechanism disengages from the base 701.

[0040] After the press-fitting is completed, the rotating mechanism rotates 90°, the front end of the motor faces the operator, the front end bearing cover is installed, and the bolts are tightened; the rotating mechanism rotates 180°, the rear end of the motor faces the operator, the rear end bearing cover is installed, and the bolts are tightened. After tightening, the rotating mechanism rotates 90°, and the operator uses the lifting tool to lift the motor down from the equipment to complete the installation work.

[0041] It can effectively realize a series of operation functions such as inserting the motor rotor, pressing the end cover, pressing the bearing, installing the inner and outer covers of the bearing and tightening the screws, realizing a unitized motor device. This equipment optimizes the assembly process, greatly improves the assembly efficiency and reduces the labor intensity.

[0042] above Figure 1-4 The unitized motor assembly equipment shown is a specific embodiment of the present invention, which has embodied the outstanding substantial features and remarkable progress of the present invention. According to actual use needs and under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
