Description

Technical Field

[0001] The invention relates to the technical field of motor housing processing, and in particular to a three-phase asynchronous motor housing punching device. Background Art

[0002] In the field of three-phase asynchronous motor manufacturing, shell punching is one of the key processes. Its processing efficiency and precision directly affect the motor performance and production cost. In the field of three-phase asynchronous motor shell processing, traditional punching equipment has many shortcomings. On the one hand, the equipment has poor adaptability. When facing motor shells with different inner diameters, it is necessary to manually replace the tooling fixtures. The debugging takes a long time and the clamping stability is insufficient. During punching, processing deviations are easily caused by the shaking of the shell. On the other hand, the tool change efficiency is low, manual tool change takes a long time, and non-working tools are exposed and prone to collision and wear. In addition, multi-angle processing is limited, and the manual positioning angle error is large, which makes it difficult to meet high-precision requirements. In view of the above problems, the present invention improves the versatility of the equipment, the tool change efficiency, and effectively solves the problems of traditional equipment through the design of adjustable support structure, conversion device and adjustment component.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention sets an adjustable support structure: the support screw drives the sleeve to move up and down, driving the pull rod to push the support plate to slide along the mounting plate, so as to accurately adapt to motor shells with different inner diameters.

[0028] Working principle: The mounting plate 31 is fixed to the inner wall of the operating table 1 as the base of the supporting device 3. When in use, the motor housing 2 is placed on the supporting plate 37 and the bottom plate 36 of the supporting device 3. The motor fixedly installed at the bottom end of the ratchet 38 drives the supporting screw 32 to rotate, so that the sleeve 311 threadedly connected thereto moves, and drives the pull rod 35 to move, thereby pushing the supporting plate 37 to move on the mounting plate 31, so that the inner wall of the motor housing 2 is supported by the supporting plate 37, and the motor housing 2 is fixed, which is convenient for fixing motor housings 2 of different sizes; At this time, the motor housing 2 is punched by the cutter 59 on the conversion device 5, and the punching cylinder 52 on the sliding frame 4 is started to drive the fixed plate 51 to slide on the inner wall of the sliding frame 4. In the process of moving downward, the displacement cylinder 55 is started to make its output end pass through the rotating disk 53 and the fixed disk 56, and enter the sliding cylinder 581 in the fixed component 58, thereby pushing the moving block 582 to move downward, and driving the cutter 59 to move downward through the connection with the tool holder 583 until it reaches the bottom end of the sliding cylinder 581, so that it is not on the same horizontal line with the cutters 59 of other sizes, preventing the cutters 59 of other sizes from contacting the operating table 1 during the downward movement during the punching process. With the push of the punching cylinder 52, the cutter 59 punches and grooves the motor housing 2, and the cut residue falls into the bottom end of the operating table 1 through the discharge port on the mounting plate 31, which is convenient for collecting the residue. When a cutter 59 of a different size is needed during the cutting process, the displacement cylinder 55 is first stopped from pushing the moving block 582. Under the action of the pushing spring 584, the moving block 582 is moved and reset in the sliding cylinder 581. During the movement of the moving block 582, the fixedly connected driving screw 586 is driven to move. Through the threaded connection with the driving screw 586, the impeller 587 is rotated at the bottom end of the sliding cylinder 581 to generate airflow, and the air outside the bottom cover 585 is blown into the sliding cylinder 581 through the vent hole 588. Under the obstruction of the moving block 582, the air moves toward the knife holder 583 and blows toward the exhaust groove 589. The outer wall of the cutter 59 is cleaned for the punching debris that may be attached to the cutter 59. At this time, the adjusting motor 54 is started, and the rotating disk 53 is driven to rotate on the outer wall of the fixed disk 56 through the pulley group 510, and the fixed component 58 equipped with a cutter 59 of another size is turned to the side of the support device 3. At this time, the displacement cylinder 55 is started again to make its output end pass through the rotating disk 53 and the fixed disk 56, and enter the sliding cylinder 581 in the fixed component 58, thereby pushing the moving block 582 to move downward, and driving the cutter 59 to move downward through the connection with the tool holder 583 until it reaches the bottom end of the sliding cylinder 581, completing the preparation for punching again; Each time the cutter 59 completes a punching action, the adjusting cylinder 33 is pushed downward, and as the adjusting cylinder 33 moves, the connecting frame 345 moves in the mounting plate 31, and during the movement, the inclined block 347 is driven to move, and the extrusion guide wheel 348 is moved by the inclined block 347, so that the sliding rod 343 fixedly connected thereto moves in the support rod 342, so that the sliding rod 343 drives the rack 341 to move, and the gear ring 39 is turned, and the block 310 on the gear ring 39 is stuck in the tooth groove on the ratchet 38 under the action of the torsion spring, so that the ratchet 38 also rotates, thereby driving the motor and the support screw 32 fixedly installed at the bottom end to rotate, thereby driving the supported and fixed motor housing 2 to rotate a certain amount, and the unfixed The processed surface faces the cutter 59; when the adjusting cylinder 33 travels to the maximum stroke, it begins to shrink and reset. At this time, under the action of the reset spring 344, the slide rod 343 drives the rack 341 to move and reset, preparing for adjusting the angle again. In this process, the gear ring 39 no longer engages with the locking ratchet 38 to prevent the supported and fixed motor housing 2 from rotating. Because the stroke of the connecting frame 345 driven by the adjusting cylinder 33 is fixed, the screw 346 is rotated to rotate on the connecting frame 345, and the threaded connected bevel block 347 is driven to move, thereby adjusting the contact distance between the bevel block 347 and the guide wheel 348, thereby adjusting the moving distance of the rack 341, and adjusting the rotation angle of the motor housing 2 on the support device 3.
