Wherein the swing arm 20 is rotatably connected with the mounting base 10, and the swing arm 20 can rotate between an unfolded position and a folded position. The tray 30 is installed at one end of the swing arm 20 far away from the installation base 10 and used for lifting a workpiece to be machined. The first limiting member 40 and the second limiting member 50 are both disposed on the mounting base 10, and the first limiting member 40 can abut against the swing arm 20 along the rotation direction of the swing arm 20 when the swing arm 20 is located at the unfolding position, so as to limit the rotation of the swing arm 20. The second stopper 50 can abut against the swing arm 20 in the rotation direction of the swing arm 20 when the swing arm 20 is located at the folded position, so as to restrict the swing arm 20 from rotating.

Referring to fig. 6 and 7, specifically, the workpiece to be processed is a motor 101, and the motor 101 is fixed on the tray 30. The swing arm 20 is rotated between the deployed position and the folded position according to the required working height of the engine 101. When the swing arm 20 is located at the extended position, the swing arm 20 abuts against the first stopper 40, so that the engine 101 has a high working height. When the swing arm 20 is located at the folding position, the swing arm 20 abuts against and is limited by the second limiting member 50, so that the engine 101 has a lower working height.

In the present embodiment, the first limiting member 40 includes an adjusting bolt, and is screwed with the mounting base 10. The adjusting bolt is adopted for adjustment, so that the structure of the whole lifting device 100 is simpler on the basis of realizing the supporting effect, and the operation is more convenient. The rotating angle of the swing arm 20 can be adjusted by adjusting the depth of the bolt screwed into the mounting seat 10, so as to adjust the working height of the engine 101.

In some embodiments, the mounting base 10 has a first mounting surface 11 and a second mounting surface 12, the first mounting surface 11 is used for connecting with an external device, and the second mounting surface 12 is used for mounting the first limiting member 40. Wherein, an included angle is formed between the first mounting surface 11 and the second mounting surface 12 along the rotation direction of the swing arm 20. Specifically, the first mounting surface 11 is connected to the assembly line 102, and an included angle is formed between the first mounting surface 11 and the second mounting surface 12 along the rotation direction of the swing arm 20. When the engine 101 is fixed to the lifting device 100, the swing arm 20 naturally rotates toward the inclined side by gravity. Under the limiting and supporting action of the first limiting member 40, the swing arm 20 is in a stable state, so that the structure of the lifting device 100 is simplified without using other structures for stabilization.

In one embodiment, when the second locking portion 53 is in the locking position, the second locking portion 53 is perpendicular to the limiting shaft 51. When the second locking portion 53 is located at the unlocking position, the second limiting member 50 is inserted into the mounting base 10 through the second locking portion 53. The second locking portion 53 is rotated to a locking position, and at this time, the second locking portion 53 cooperates with the first locking portion 52, so that the limiting shaft 51 is locked to the mounting seat 10 along the axial direction thereof. The second limiting member 50 can be prevented from falling off from the mounting base 10 in the process that the lifting device 100 runs along with the assembly line 102, so that the swing arm 20 rotates to influence the running of the assembly line 102.

In some embodiments, the end of the second locking portion 53 away from the limiting shaft 51 has a tapered portion 531 extending along the axial direction of the limiting shaft 51, and the diameter of the tapered portion 531 decreases from the side close to the limiting shaft 51 to the side away from the limiting shaft 51. When the second limiting member 50 is inserted into the mounting base 10, the tapered portion 531 inserts into the mounting hole of the mounting base 10, so that the inserting process is smoother.
