Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and in particular to a shell pressing device for assembling a super-efficient aluminum shell motor. Background Art

[0002] The motor housing consists of an outer shell and an inner shell. The inner shell is meticulously designed with channels for cooling. During assembly, the inner shell is typically heated to increase its inner diameter. A press fit then presses the inner shell into the outer shell. Once the outer shell cools, the inner shell is securely clamped into the outer shell, completing the motor's inner and outer shell assembly.

[0003] However, the existing pressing device's operation is quite cumbersome. The outer shell must first be placed in a designated location, then moved to a heating station for heating. After heating is complete, the inner shell must be replaced. Once the outer shell is heated, a robotic arm must be used to lift the inner shell. Simultaneously, the outer shell must be moved back to its original position, and finally, the robotic arm presses the inner shell into the outer shell. This series of operations not only requires the separate placement of the inner and outer shells, but also creates a complex process, significantly reducing processing efficiency.

[0028] like Figure 2 、 Figure 5 and Figure 6As shown, the placement component includes a bracket 61, a fixing rod 62, a bidirectional screw rod 63, a servo motor 64, a bearing plate 65, a limit block 66, a U-shaped limit plate 67, a return spring 68 and a trapezoidal extrusion block 69. The bracket 61 is welded and fixed to the left and right sides of the top rear side of the workbench 1 table panel, and a fixing rod 62 is welded and fixed between the upper front sides of the two brackets 61. A bidirectional screw rod 63 is rotatably connected between the upper rear sides of the two brackets 61. A servo motor 64 is installed on the upper part of the right bracket 61 by bolts, and the output shaft end of the servo motor 64 is fixedly connected to the right end of the bidirectional screw rod 63. Two bearing plates 65 are slidingly arranged between the fixing rod 62 and the bidirectional screw rod 63. The two bearing plates 65 and the bidirectional screw rod 63 are threaded together. When the bidirectional screw rod 63 rotates, the two bearing plates 65 that can be brought closer to or away from each other are welded and fixed at intervals on the top of the two bearing plates 65. Limit blocks 66, the inner walls of the four limit blocks 66 can fit into the outer walls of the inner shell 002, so as to position the inner shell 002 so that it can be aligned with the outer shell 001 in the vertical direction. A U-shaped limit plate 67 is slidingly provided in the middle of the two supporting plates 65. Two fixing plates for installing positioning screws are provided on the lower side of the inner wall of the inner shell 002. The U-shaped limit plate 67 can limit the fixed plate to limit the rotation of the inner shell 002. Two return springs 68 are connected between the two U-shaped limit plates 67 and the adjacent supporting plates 65. Trapezoidal extrusion blocks 69 are welded and fixed to the bottom of the two U-shaped limit plates 67. The trapezoidal extrusion blocks 69 are cut with an inclined surface on the side close to the adjacent bracket 61. The reduction motor 34, the electric heating rod 43, the electric push rod 55, and the servo motor 64 are all electrically connected to the external controller. The controller has a built-in control module that can realize automatic control of the electric heating rod 43, etc.

[0029] First, the staff starts the reduction motor 34 through the external controller, and the output shaft of the reduction motor 34 starts to rotate, which drives the screw 33 to start rotating through the transmission of the two bevel gears 35. Under the guidance of the column 32, the screw 33 rotates and drives the lifting platform 41 to move downward to Figure 2As shown in the position, at this time, the staff places the outer shell 001 on the top of the fixing ring 2, and uses the positioning ring 21 to position the outer shell 001. Then, the inner shell 002 is placed between the tops of the two bearing plates 65, and the inner shell 002 is positioned together by four limit blocks 66 and U-shaped limit plates 67. Subsequently, the staff starts the external controller, and the controller immediately controls the reduction motor 34 to start and reverse, driving the lifting platform 41 to move upward and reset. During the resetting process of the lifting platform 41, the mounting column 42 moves upward with the lifting platform 41 until it is aligned with the outer shell 001, so that the electric heating rod 43 can be close to the inner wall of the outer shell 001. At the same time, the fixing column 51 follows As the mounting post 42 moves upward, the bottom height of the pressing plate 57 is flush with the top height of the inner shell 002, and the clamping block 54 is located inside the inner shell 002. At this time, the controller starts the electric heating rod 43 and the electric push rod 55. After the electric heating rod 43 is started, the inner wall of the outer shell 001 is heated, and the inner diameter of the outer shell 001 is increased by the principle of thermal expansion and contraction. After the electric push rod 55 is started, the telescopic rods of the two electric push rods 55 are extended synchronously, and under the guidance of the guide rod 53, the two clamping blocks 54 are pushed to move away from each other until they are respectively in contact with the front and rear inner walls of the inner shell 002, thereby clamping and fixing the inner shell 002. When the inner shell 002 is in motion, the two pressing plates 57 are driven to move away from each other through the two connecting rods 58 until the two pressing plates 57 are in contact with the front and back sides of the top of the inner shell 002. After the inner shell 002 is clamped, the controller starts the servo motor 64, and the output shaft of the servo motor 64 starts to rotate. Under the guidance of the fixed rod 62, the two supporting plates 65 are driven to move away from each other. When the supporting plate 65 moves, the U-shaped limiting plate 67 moves therewith, driving the trapezoidal extrusion block 69 to contact with the adjacent bracket 61. The inclined surface cut on the trapezoidal extrusion block 69 contacts the upper part of the bracket 61 and is squeezed, thereby driving the U-shaped limiting plate 67 to slide downward until the U-shaped The top height of the limit plate 67 is flush with the top height of the supporting plate 65. At this time, the return spring 68 is stretched, and the supporting plate 65 can be smoothly pulled out from the top of the inner shell 002. After the heating of the inner wall of the outer shell 001 is completed, the controller controls the electric heating rod 43 to turn off, and starts the reduction motor 34 again. The reduction motor 34 drives the lifting platform 41 to move downward, and the fixed column 51 drives the inner shell 002 to move downward through the clamping block 54 and the pressing plate 57, pressing the inner shell 002 into the outer shell 001, realizing the pressing of the outer shell 001 and the inner shell 002. This process is simple and does not require the outer shell 001 and the inner shell 002 to be placed at intervals, which saves time and effort and greatly improves the pressing efficiency.

[0030] like Figure 7As shown, it also includes a mounting plate 71, a nozzle 72, a fan 73, an air outlet pipe 74, a diversion pipe 75 and a connecting pipe 76. Two mounting plates 71 are welded and fixed at intervals on the upper part of the two brackets 61. The nozzles 72 are welded and fixed on the mounting plates 71. The nozzles 72 are all arranged in an inclined manner and face the shell 001. A fan 73 is installed on the top rear side of the workbench 1. The bottom of the fan 73 is connected to the air outlet pipe 74. The end of the air outlet pipe 74 is fixedly connected to the diversion pipe 75. Connecting pipes 76 are connected between the diversion pipe 75 and the four nozzles 72. The fan 73 is electrically connected to the above-mentioned controller.

[0031] After the inner shell 002 is pressed into the outer shell 001, the controller starts the fan 73, and the fan 73 blows out air through the air outlet pipe 74. The air passes through the diversion pipe 75 and the four connecting pipes 76 and enters the nozzle 72, and is blown out by the nozzle 72, cooling the outer shell 001, so that the inner diameter of the outer shell 001 is quickly restored, and the inner shell 002 is clamped, thereby realizing the rapid assembly of the outer shell 001 and the inner shell 002.

[0032] like Figure 1 and Figure 8 As shown, it also includes a shell a81 and a shell b82. The shell a81 is welded and fixed to the right side of the reduction motor 34, and the shell b82 is detachably fixed to the right side of the shell a81 by bolts.

[0033] By providing the housing a81 and the housing b82 , the bevel gear 35 is enclosed to prevent foreign matter from getting stuck in the bevel gear 35 and affecting its normal use.

[0034] like Figure 1 As shown, a placement plate 9 is also included, and the placement plate 9 is welded and fixed to the left side of the table panel of the workbench 1.

[0035] By setting up the placement plate 9, when the outer shell 001 and the inner shell 002 are pressed together, the staff will take them out and place them on the placement plate 9, and then immediately place a new outer shell 001 and inner shell 002. During the process of heating the new outer shell 001 and pressing the inner shell 002, the staff can move the outer shell 001 and inner shell 002 after pressing to the next work station, thereby improving processing efficiency.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
