Example

[0032] The motor housing riveting tool capable of automatic positioning is provided with a clamping pressure structure, which can make the motor housing vertically downward for easy positioning, specifically:

[0033] The upper surface of the housing 1 is provided with a clamping pressure structure, which can clamp the upper end of the motor housing to limit the position and press it downward by a clamping block 17.

[0034] When the motor housing riveting tool capable of automatic positioning is used, Figure 1 As shown, first, the two clamping blocks 17 are pulled apart so that the motor casing is located on the lower surface of the pressure plate 16, and then the clamping blocks 17 are released so that the clamping blocks 17 clamp the upper end of the motor casing under the rebound force of the spring 18, and then the cylinder 2 15 on the upper surface of the housing 1 is opened, and the telescopic rod 5 of the cylinder 2 15 will press the pressure plate 16, so that the pressure plate 16 presses the motor casing downward. Example

[0035] On the basis of Example 1, a positioning structure is further provided, which can perform drilling positioning by controlling the downward pressing distance of the movable plate 3 and coordinating with the chuck 8 to place the housing offset, specifically:

[0036] A base 2 is installed on the lower surface of the inner wall of the shell 1, and a groove is provided on the upper surface of the base 2, and a moving plate 3 is slidably installed in the groove. The base 2 is connected to a positioning structure, and an airbag 4 is installed on the lower surface of the moving plate 3. An air pipe 6 is connected to the outer surface of the airbag 4, and the other end of the air pipe 6 penetrates the upper surface of the base 2 and is connected to the connecting frame 7. A slider is provided on the side surface of the moving plate 3, and the slider slides through the slotted side surface of the base 2. A telescopic rod 5 is fixedly connected to the lower surface of the slider of the moving plate 3, and the lower end of the telescopic rod 5 is fixedly installed on the lower surface of the inner wall of the base 2, and a chuck 8 is installed on the side surface of the connecting frame 7;

[0037] When the motor housing is downward, the lower end of the motor housing will contact the moving plate 3 installed in the slotted sliding on the upper surface of the housing 1, such as Figure 3As shown, the movable plate 3 is pressed downward, and at the same time, the slider of the movable plate 3 slides, and the telescopic rod 5 fixedly connected to the lower surface of the slider is pressed downward at the same time, and the airbag 4 installed on the lower surface of the movable plate 3 is also pressed. The airflow in the airbag 4 will pass through the air pipe 6 and the connecting frame 7 into the bag body embedded in the chuck 8, so that the chuck 8 limits the outer surface of the motor casing to prevent the motor casing from shifting and tilting. Furthermore, when the movable plate 3 moves to the lowest point, the preset drill hole in the motor casing will also correspond to the rivet 11. Example

[0038] On the basis of embodiments 1 and 2, a nailing structure is further provided, which can complete the riveting through the cooperation of the slotted rod 9 and the limiting plate 10, specifically:

[0039] The connecting frame 7 is also connected to a nailing structure, which can connect the rivet 11 to the opening of the motor housing through the slotted rod 9. The nailing structure includes a vertical plate 14, which is installed on the upper surface of the base 2. The side surface of the vertical plate 14 is fixedly penetrated by the connecting frame 7.

Figure 5 As shown, the upper surface of the slotted rod 9 is provided with a slot, and the slot is engaged with one end of the nail core of the rivet 11, so the slotted rod 9 pushes the front end of the rivet 11 into the drilled hole of the casing, and then the cylinder 13 below is opened, which will push the limiting plate 10 to move, and press the nail head of the rivet 11 on the outer surface of the motor casing, and then the slotted rod 9 is connected to the cylinder 13 to open, so that the piston rod of the cylinder 13 retracts, driving the slotted rod 9 to pull the nail core of the rivet 11, so that the rivet 11 rivets the motor casing, and then the remaining nail core in the slotted rod 9 corresponds to the electromagnet 12. After the electromagnet 12 is energized, the nail core is sucked up, which is convenient for the staff to take out, and then a new rivet 11 is put into the slotted rod 9 for the next use.

[0041] Working principle: When using the motor casing riveting tool that can automatically position, the clamping pressure structure presses the motor casing downward, while the side of the motor casing is offset through the point structure, and the drilled holes are made to correspond to the rivets 11. Finally, the riveting is completed through the cooperation of the slotted rod 9 and the limiting plate 10 of the nailing structure, which increases the overall practicality.
