DETAILED DESCRIPTION

[0022] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4 As shown, this embodiment is an automatic loading and unloading mechanism for processing a square rotor, comprising a positioning assembly 1 and a clamping assembly 2. The positioning assembly 1 comprises a bottom plate 11 and a positioning joint 12 for inserting into the inner hole of the rotor. The bottom plate 11 is provided with a positioning groove 111 adapted to the rotor shape and a through hole 112 located below the positioning groove 111. The positioning joint 12 extends from the through hole 112 and the positioning groove 111 in sequence; the clamping assembly 2 comprises a pressing plate 21, a lifting plate 22, a lifter 23 and a connecting slide rod 24. The lifter 23 is retractable. The end is connected to the middle part of the lifting plate 22, the two ends of the connecting slide bar 24 are respectively connected to the pressing plate 21 and the lifting plate 22, and the connecting slide bar 24 is provided with a spiral guide groove 241, and a plug rod 25 adapted thereto is inserted into the spiral guide groove 241; one end of the positioning joint 12 is connected to the lifting plate 22, and the positioning joint 12 and the pressing plate 21 are pulled down by the lifter 23, and the pressing plate 21 is simultaneously driven to rotate to the top of the positioning groove 111 to press the rotor; specifically, in the initial state, the positioning joint 12 extends from the bottom plate 11, and a grabbing robot is used The four-sided rotor is inserted into the positioning joint 12 to lift it, and the lifter 23 pulls down the lifting plate 22 to move the positioning joint 12 and the pressure plate 21 downward, and the positioning joint 12 retracts into the through hole 112, and the four-sided rotor is left in the positioning groove 111. The thickness of the four-sided rotor is greater than the depth of the positioning groove 111. During the synchronous downward movement of the lifting plate 22 and the pressure plate 21, due to the cooperation of the insertion rod 25 and the spiral guide groove 241, the pressure plate 21 will rotate a certain angle during the downward movement, and the pressure plate 21 will turn to the top of the four-sided rotor and The pressing, positioning and clamping processes are carried out simultaneously to ensure that after the square rotor is completely placed in the positioning groove 111, the pressure plate 21 is rotated into place and pressed down to tighten. After the processing is completed, the lifter 23 drives the positioning joint 12 and the pressure plate 21 to rise. The pressure plate 21 moves away from the top of the positioning groove 111 while rising. The positioning joint 12 passes through the inner hole of the square rotor to lift it from the positioning groove 111, avoiding the problem that the square rotor is stuck in the positioning groove 111 and is difficult to remove, which greatly improves the processing efficiency and facilitates the inner hole milling of the square rotor.

[0023] It is possible that the lifter 23 may be a pneumatic cylinder or an electric cylinder.

[0024] like Figure 1 and Figure 2 As shown, the lower end of the connecting slide bar 24 in the present invention is axially spaced with a first snap ring 242 and a second snap ring 243, the connecting slide bar 24 passes through the lifting plate 22 and is slidably connected thereto, and the lifting plate 22 is clamped between the first snap ring 242 and the second snap ring 243; specifically, in order to ensure that there is a time difference between the blanking and pressing processes and to prevent the pressing plate 21 from rotating too quickly and colliding with the positioning joint 12 or the square rotor, the lifting plate 22 abuts against the first snap ring 242 before moving down, and in the first half of the downward movement, the lifting plate 22 is slidably connected to the connecting slide bar 24, and before the positioning joint 12 is about to separate from the square rotor and retract into the through hole 112, the lifting plate 22 contacts the second snap ring 243 to pull the connecting slide bar 24 downward, and due to the cooperation of the insertion rod 25 and the spiral guide groove 241, the connecting slide bar 24 rotates at a certain angle, so that the pressing plate 21 rotates to the top of the positioning groove 111 to press the square rotor.

[0025] As an option, Figure 2 As shown, this embodiment also includes an air-blowing slag-cleaning component 3, which includes a folding bag 31 and an air-blowing pipe 32. The two ends of the folding bag 31 are respectively connected to the lower ends of the lifting plate 22 and the bottom plate 11, one end of the air-blowing pipe 32 is connected to the top of the folding bag 31, and the other end of the air-blowing pipe 32 extends from the inner wall of the through hole 112. Specifically, when the inner hole of the square rotor is milled, a part of the debris will remain on the through hole 112 and the positioning joint 12, so that the positioning joint 12 may produce extrusion to affect the accuracy of the inner hole when the processed square rotor is ejected. In addition, when the material is connected, the square rotor cannot be inserted into the positioning joint 12 or is in a flat state, so that the square rotor may not be correctly placed in the positioning groove 111. By arranging the folding bag 31 between the lifting plate 22 and the bottom plate 11, the lifting plate 22 can squeeze the folding bag 31 during the upward movement, and the squeezed air is ejected from the air-blowing pipe 32 to blow the positioning joint 12 to blow the debris clean.

[0026] The lifting plate 22 moves downward to pull the folding bag 31 to return to its original position, and the air blowing tube 32 sucks air to refill the folding bag 31 for next use.

[0027] In order to prevent debris from being discharged from the bottom of the through hole 112 , the air blowing pipes 32 are evenly spaced on the inner wall of the through hole 112 and tilted downward so that the air blowing pipes 32 can blow the positioning joint 12 from the top to the bottom.

[0028] like Figure 2 and Figure 3As shown, in some embodiments, a cutter hole 211 is provided at one end of the pressure plate 21, and the size of the cutter hole 211 is larger than the inner hole of the rotor; specifically, during the clamping process, the center of the cutter hole 211 preferably coincides with the center of the square rotor, and the milling cutter is extended vertically to process the inner hole of the square rotor. The cutter hole 211 can facilitate cutting and cause processing interference to the milling cutter.

[0029] More preferably, support guide rods 4 are respectively provided under the bottom plate 11, and the two ends of the lifting plate 22 are respectively slidably connected to the support guide rods 4, and the lifter 23 acts on the middle part of the lifting plate 22 and is slidably connected with the support guide rods 4 on both sides, thereby ensuring the smoothness and accuracy of the vertical lifting of the lifting plate 22.

[0030] like Figure 2 As shown, in some embodiments, the front end of the positioning joint 12 includes a plug portion 121 and a limit portion 122, the plug portion 121 is adapted to the inner hole of the rotor, and the limit portion 122 is larger than the inner hole of the rotor; specifically, the plug portion 121 is used to insert into the inner hole of the square rotor until the limit portion 122 is against the bottom of the square rotor to lift it so that it is in a relatively horizontal state and then moved down to be placed in the positioning groove 111.

[0031] As an option, Figure 4 As shown, the plug portion 121 in this embodiment adopts a square head spiral structure, and the plug portion 121 gradually increases from the front end to the rear end; specifically, when connecting the materials, the inner hole of the square rotor can be directly covered on the plug portion 121, and the inner hole of the square rotor automatically rotates to the bottom following the square head spiral structure, and the square rotor is attached to the limit portion 122 to complete the automatic positioning of the square inner hole.

[0032] In order to catch the debris dropped during inner hole milling and air blowing, a slag receiving bucket 5 is provided below the positioning joint 12, and the slag receiving bucket 5 is located at the lower side of the through hole 112; the slag receiving bucket 5 is a bell-mouth structure, and a storage bag can be provided below the slag receiving bucket 5 for storage.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
