[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The first placement clamp drives the motor housing to a suitable position on the surface of the two slide rails. The first lifting cylinder drives the heater to move. The heater drives the two sets of guide columns and U-shaped parts to move. The downward movement is limited until it is engaged with the inner wall of the motor housing. Several electric heating tubes heat the heater. The outer side of the heater heats the inner wall of the motor housing for a preset time. The temperature measuring instrument on the surface of the mounting rod monitors the temperature of the motor housing in real time. When the preset temperature range is reached, the heating stops, thereby improving the heating effect of the motor housing.

[0015] (2) By placing the inner sleeve of the workpiece on the surface of the second placement fixture, and using photoelectric sensors to position the clamping position, the second lifting cylinder drives the pressing seat to move. The pressing seat drives two linear guides to move on the inner walls of the two limit frames, limiting their movement until the pressing seat drives the pneumatic three-jaw chuck to engage with the inner wall of the inner sleeve of the workpiece. Then the inner sleeve of the workpiece is clamped and moved upward. The first placement fixture drives the heated motor housing to move to the initial position. The two sets of photoelectric sensors on the surfaces of the two mounting columns reposition the pressing position of the motor housing. After that, the second lifting cylinder, in conjunction with the pressing seat and the pneumatic three-jaw chuck, drives the inner sleeve of the workpiece to move downward, pressing the inner sleeve of the workpiece into the interior of the motor housing after thermal expansion. This avoids the damage caused by traditional pressing, which affects the subsequent motor quality and lifespan. Attached Figure Description

[0023] Please see Figure 3 The heating monitoring component 2 includes a first lifting cylinder 21 installed in the middle of one side of the top of the lower frame 1. The output rod of the first lifting cylinder 21 is fixedly connected to a heater 22. The four corners of the top of the heater 22 are provided with guide posts 23. The tops of the two sets of guide posts 23 are inserted and connected to one side of the top of the lower frame 1. The tops of the two sets of guide posts 23 are fixedly connected to a U-shaped piece 24. The heater 22 has several electric heating tubes inside. The side of the heater 22 is engaged with the inner wall of the motor housing 15 on the top of the first placement fixture 13. The outside of the motor housing 15 is provided with a thermometer 25. The thermometer 25 is set on the surface of the mounting rod 26 on one side of the top of the support plate 11.

[0024] In practical use: the first placement clamp 13 moves the motor housing 15 to a suitable position on the surface of the two slide rails 12. The first lifting cylinder 21 moves the heater 22. The heater 22 moves the two sets of guide columns 23 and U-shaped parts 24, limiting its downward movement until it is engaged with the inner wall of the motor housing 15. Several electric heating tubes heat the heater 22. The outer side of the heater 22 heats the inner wall of the motor housing 15 for a preset time. The temperature measuring instrument 25 on the surface of the mounting rod 26 monitors the temperature of the motor housing 15 in real time. Heating stops when the preset temperature range is reached, thus improving the heating effect of the motor housing 15.

[0025] Please see Figure 4The positioning and pressing assembly 3 includes a second lifting cylinder 31 installed in the middle of the other side of the top of the lower frame 1. The output rod of the second lifting cylinder 31 is fixedly connected to the pressing seat 32. The pressing seat 32 has linear guide rails 33 on both sides of the top. The surfaces of the two linear guide rails 33 are inserted and connected to the inner walls of the two limit frames 34. The surfaces of the two limit frames 34 are inserted and fixed to one side of the top of the lower frame 1. The bottom of the pressing seat 32 is provided with a pneumatic three-jaw 35. The side of the pneumatic three-jaw 35 is engaged and connected to the inner wall of the workpiece inner sleeve 16 provided on the top of the second placement fixture 14. The top two sides of the support plate 11 are provided with mounting posts 36 at the center line of the second placement fixture 14. The surfaces of the two mounting posts 36 are provided with two photoelectric sensors 37.

[0026] In practical use: The inner sleeve 16 of the workpiece is placed on the surface of the second placement fixture 14, and the clamping position is positioned with the help of the photoelectric sensor 37. The second lifting cylinder 31 drives the pressing seat 32 to move. The pressing seat 32 drives the two linear guide rails 33 to move on the inner wall of the two limit frames 34, limiting their movement until the pressing seat 32 drives the pneumatic three-jaw 35 to engage with the inner wall of the inner sleeve 16 of the workpiece. Then the inner sleeve 16 of the workpiece is clamped and moved upward. The first placement fixture 13 drives the heated motor housing 15 to move to the initial position. The two sets of photoelectric sensors 37 on the surface of the two mounting columns 36 reposition the pressing position of the motor housing 15. After that, the second lifting cylinder 31, together with the pressing seat 32 and the pneumatic three-jaw 35, drives the inner sleeve 16 of the workpiece to move downward, pressing the inner sleeve 16 of the workpiece into the interior of the motor housing 15 after thermal expansion. This avoids the damage caused by traditional pressing, which affects the subsequent quality and life of the motor.

[0027] Please see Figure 3 A scald-proof isolation net 17 is installed in the middle of the top of the inner wall of the lower frame 1.

[0031] Please see Figure 1 A displacement sensor 111 is installed in the middle of the other side of the top of the lower frame 1.

[0032] In practical use: The displacement sensor 111 located in the middle of the other side of the top of the lower frame 1 facilitates the monitoring of the downward movement distance of the lifting structure, thus avoiding product damage caused by movement.

[0033] Please see Figure 2 Pressure gauge 112 and touch screen 113 are respectively installed on the upper side of one side of the lower frame 1, and safety doors 114 are installed on the other three sides of the lower frame 1.

[0034] In actual use: the pressure gauge 112 on the upper side of the lower frame 1 can display the pressing force, and the touch screen 113 can adjust the real-time data of the device.

[0035] Please see Figure 2 An electrical box 115 is installed inside the bottom of the lower frame 1, and a three-color light 116 is installed at one corner of the top of the lower frame 1.

[0036] In practical use: the electrical box 115 inside the bottom of the lower frame 1 provides power to the device, and the three-color light 116 on the top of the lower frame 1 displays the different states of the pressing equipment during the pressing process.

[0037] Please see Figure 4 Dust blowing pipes 117 are provided at the four corners of the top of the first placement fixture 13.

[0038] In practical use: the two sets of dust blowing pipes 117 at the four corners of the top of the first placement fixture 13 can start blowing air after the pressing is completed, which can clean the dust of the workpiece placement fixture and cool the workpiece.

[0039] In use, the barcode scanner 110 converts the optical information of the barcodes on the surfaces of the motor housing 15 and the workpiece inner sleeve 16 to be pressed into digital signals that can be recognized by a computer, thereby completing data statistics. In conjunction with the button panel on the touchscreen 113, the controllable structures on the equipment are interacted with via touch. The first placement fixture 13 moves the motor housing 15 to a suitable position on the surfaces of the two sliding guide rails 12. The first lifting cylinder 21 moves the heater 22, which in turn moves the two sets of guide columns 23 and the U-shaped component 24, limiting their downward movement until they engage with the inner wall of the motor housing 15. Several heating tubes heat the heater 22, and the outer side of the heater 22 heats the inner wall of the motor housing 15 for a preset time. The temperature sensor 25 on the surface of the mounting rod 26 monitors the temperature of the motor housing 15 in real time, stopping heating when the preset temperature range is reached. Simultaneously with heating, the workpiece inner sleeve 16 is placed in the second placement fixture. The surface of 14, in conjunction with the photoelectric sensor 37, positions the clamping position. The second lifting cylinder 31 drives the pressing seat 32 to move. The pressing seat 32 drives two linear guide rails 33 to move on the inner wall of the two limit frames 34, limiting their movement until the pressing seat 32 drives the pneumatic three-jaw 35 to engage with the inner wall of the workpiece inner sleeve 16. Then, the workpiece inner sleeve 16 is clamped and moved upward. The first placement fixture 13 drives the heated motor housing 15 to move to the initial position. The two sets of photoelectric sensors 37 on the surface of the two mounting columns 36 reposition the pressing position of the motor housing 15. At the same time, the two safety light curtains 18 trigger the safety mechanism through infrared beam blocking detection during the pressing process, which can protect the operator or equipment. Afterward, the second lifting cylinder 31, in conjunction with the pressing seat 32 and the pneumatic three-jaw 35, drives the workpiece inner sleeve 16 downward, pressing the workpiece inner sleeve 16 into the interior of the motor housing 15 after thermal expansion, avoiding the damage caused by traditional pressing.
