The clamping device 83 is clamped by the center correction module 832. Perform position correction to correct the position deviation that exists when the parts are aligned. When a position error or angle error occurs between the pressed part and the pressed hole, the center correction module 832 can use the assembly chamfer between the workpieces to guide the pressed part into the pressed hole, thereby completing the assembly operation. The center correction module 832 uses multiple sets of spring columns 8321 inside to cause horizontal displacement or angle change under the action of the assembly chamfer, so that the pressed part is correctly assembled in the assembly hole. After the operation is completed, the center correction module 832 can return to the initial position under the elastic action of the internal spring column 8321 to prepare for the next operation. The heating device 7 and the clamping and pressing equipment 8 both enter the insulation box 5 through the connecting hole 53, and after the pressing work is completed, the insulation box 5 can cool the parts in the insulation box through the air inlet pipe 52, and then discharge the hot air in the insulation box 5 through the air outlet pipe 51.

[0028] Working principle: When using a motor housing water jacket heating and pressing equipment, first place two groups of parts that need to be stamped and assembled on the No. 1 conveying platform 31 and the No. 2 conveying platform 32 on the work station 3, respectively, and then start the machine for pressing. The No. 1 conveying platform 31 is driven by the No. 1 conveying motor 311 to move along the direction of the No. 1 conveying track 312, and in the process of moving, it drives the parts placed on the No. 1 conveying platform 31 to move, and transports the parts to the insulation box 5. At the same time, the No. 2 conveying platform 32 is driven by the No. 2 conveying motor 321 to move along the direction of the No. 2 conveying track 322, and in the process of moving, it drives the parts placed on the No. 2 conveying platform 32 to move, and under the action of the laser centering device 6, the No. 1 conveying platform 31 and the No. 2 conveying platform 32 are stopped at the specified position.

[0029] When both groups of parts are transported to the designated position, the safety door 21 on the housing 2 is lowered to isolate the press-fitting equipment from the staff. After the safety door 21 is completely lowered, the heating device 7 is driven by the moving device 73 to move along the direction of the second slide 92. When it moves to the top of the connecting hole 53 above the heat preservation box 5, the heating core 72 is pushed downward by the first stamping cylinder 71 to extend the heating core 72 into the inner cavity of the assembled part for heating, so that it expands by heat. After heating for a specified time, the heating core 72 is pressed by the first stamping cylinder 71. The heating core 72 is lifted up, and then driven by the moving device 73 to move back to the initial position along the direction of the No. 2 slide groove 92, and then the No. 2 stamping cylinder 81 drives the telescopic rod 811 to extend and retract, and the two groups of fixed clamps 834 at the bottom of the fixed clamp 833 are brought close to each other to clamp the parts located above the No. 2 conveying platform 32, and then the clamping and pressing equipment 8 slides in the No. 2 slide groove 92 along the direction of the connecting slide rail 911 through the sliding connecting plate 82, and during the sliding process, the parts clamped on the clamping device 83 are driven to move.

[0030] When the clamping and pressing equipment 8 moves with the parts to the top of the insulation box 5, the telescopic rod 811 is driven downward by the No. 2 stamping cylinder 81, and the clamping device 83 and the parts clamped by it are driven to move during the movement, so that the parts are aligned with the inner cavity of another assembly part. When there is a position error or angle error between the pressed part and the pressed hole, the center correction module 832 can use the assembly chamfer between the workpieces to guide the pressed part into the pressed hole, thereby completing the assembly operation. The center correction module 832 undergoes horizontal displacement or angular change under the action of the assembly chamfer through the multiple sets of spring columns 8321 inside, so that the pressed part is correctly assembled in the assembly hole. After the operation is completed, the center correction module 832 can return to the initial position under the elastic action of the internal spring column 8321, and then press the part to press the part into the installation cavity of the assembly part.

[0031] After the pressing work is completed, the clamping and pressing equipment 8 slides in the No. 2 slide groove 92 along the direction of the connecting slide rail 911 through the sliding connecting plate 82 and returns to the initial position. At the same time, the insulation box 5 cools the parts in the insulation box through the air inlet pipe 52, and then discharges the hot air in the insulation box 5 through the air outlet pipe 51. After cooling is completed, the safety door 21 opens, and the No. 1 conveying platform 31 and the No. 2 conveying platform 32 return to the initial position under the action of their respective connected motors, and when the No. 1 conveying platform 31 moves, it drives the parts above it that have been pressed to move together, waiting for the operator to perform subsequent processes.
