Description

Technical Field

[0001] This invention relates to the field of motor housing processing technology, specifically a cutting device for processing the housing of a vibration motor. Background Technology

[0002] As an important power device, the housing of a vibratory motor is usually a thin-walled cylindrical casting made of cast iron or aluminum alloy. The housing is then installed on one side of the rotor to protect the rotor and meet the working requirements. At present, the machining of such housings is mostly carried out by traditional lathes or vertical machining centers. However, there are several technical bottlenecks in the actual production process, which seriously affect the machining quality and efficiency. Existing methods for machining motor housings face the following technical challenges: Motor housings are thin-walled components with relatively poor structural rigidity. When using traditional three-jaw chucks or specialized clamps for radial clamping, uneven clamping forces easily lead to elastic deformation of the workpiece. While the dimensions may be within acceptable limits during machining, the workpiece springs back after the clamping force is released, causing significant deviations in roundness, cylindricity, and other geometric tolerances. Furthermore, the inherent dimensional errors in the housing itself make rapid and accurate positioning difficult. Manual alignment is time-consuming, labor-intensive, and lacks guaranteed accuracy. Therefore, a cutting device for machining vibration motor housings is proposed to address these issues. Summary of the Invention

[0012] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. The cutting device for machining the housing of this vibratory motor uses a rotating mechanism and a tension spring to provide a constant initial feed force. At the same time, the "one-way ratchet" mechanism, which is formed by a lever and a limiting hole with a rectangular chuck, enables the cutting process to be adaptive. When encountering uneven wall thickness or casting defects, the cutting reaction force can push the cutting machine to retract radially for buffering. When the cutting conditions are normal, the mechanism can lock and allow continuous feed, which can greatly avoid tool breakage, chipping, or even workpiece damage caused by sudden changes in cutting force. It is particularly suitable for machining the casting housing of vibratory motors.

[0013] 2. The cutting device for machining the housing of this vibratory motor achieves automatic centering and uniform clamping of the housing through the synchronous centripetal movement of multiple wedge-shaped clamping blocks in the clamping mechanism under the action of tension springs. This eliminates the tediousness and errors of manual alignment, ensuring that the center of the housing coincides with the cutting rotation center, thus guaranteeing the roundness and coaxiality of the machining from the source. At the same time, the one-button operation reset component can quickly release the clamping, achieving efficient clamping and unloading, and significantly improving production efficiency.

[0014] 3. The cutting device for machining the housing of this vibratory motor has a protective mechanism and a stable support mechanism. The protective plate achieves intelligent protection by automatically opening during machining and automatically closing when the machine stops through the synergistic effect of centrifugal force and spring, which avoids chips from getting tangled on the tool or workpiece and potentially damaging the machined surface. The support mechanism provides a stable bottom support for the housing through the cooperation of the insert rod and the insert hole. Attached Figure Description

[0025] A protective mechanism 8 is provided below the mounting plate 47 for protection during cutting.

[0026] Working principle: The housing 5 is inserted through the circular hole of the cutting table 1, and its bottom rests on the support circular plate 72 of the support mechanism 7. At this time, under the pushing force of the spring 3 74, the housing 5 is lifted upward. At this time, pressing down on the housing 5 will push the support plate 72 to slide inside the inner cylinder 71, while the insertion rod 75, under the tension of the tension spring 76, automatically inserts into the insertion hole on the side wall of the inner cylinder 71, locking the height of the support plate 72 and providing stable bottom support for the housing 5. Subsequently, under the continuous tension of the tension spring 65, the fixing ring 64 will be pulled and the push rod 63 will move towards the center, thereby causing the wedge-shaped clamping block 66 to retract towards the center in sync, thus achieving a tight grip on the outer circle of the housing 5 and completing automatic centering and strong clamping. The drive ring 42 rotates along the track 41, causing the entire rotating mechanism 4 and the cutting machine 3 mounted on it to revolve around the fixed housing 5, achieving circumferential cutting and radial adaptive feed. Initial feed: Under the continuous tension of the tension spring 45, the U-shaped plate 46 tends to move towards the center through the slide rod 44, pushing the cutting machine 3 to feed radially towards the outer wall of the housing 5. When the blade of the cutting machine 3 contacts the outer wall of the housing 5 and begins to cut, it will be subjected to radial reaction force. If the outer wall thickness of the housing 5 is uneven or there are casting defects that cause a sudden change in cutting force, this force will push the U-shaped plate 46 to overcome the tension of the tension spring 45 and move slightly outward to achieve buffering and avoidance, preventing blade jamming or blade breakage. The lever 410 will slide in the limiting hole 48 to adapt to the adaptive feed when the housing 5 is being cut. Feed locking and follow-up: Under the thrust of spring 411, the top of lever 412 is always locked in the rectangular slot of the limiting hole 48 of U-shaped plate 46. This mechanism is like a "one-way pawl", allowing U-shaped plate 46 to move outward when pushed. Lever 412 slides out of one slot, but at this time spring 411 will push slider 410 to slide on arc rod 49 and push lever 412 into a new slot. In this way, the position of U-shaped plate 46 can be adjusted and fixed according to the different diameters of the housing 5, so as to realize the adjustment of the position of cutting machine 3 for cutting.

[0027] After the machining is completed, the automatic reset is performed. Rotating the lead screw 674 pushes the synchronizing block 677 and the limiting rod 675 to move, which in turn drives the arc-shaped push block 673 to slide the two arc-shaped blocks 672 from the arc-shaped through hole 671. At this time, the arc-shaped blocks 672 will push open the wedge-shaped clamping block 66, overcome the tension of the tension spring 65, and force all the wedge-shaped clamping blocks 66 to release the machine housing 5 simultaneously. Rotating the lead screw 79 pushes the reset block 710 and its reset rod inward, pushing the insertion rod 75 out of the insertion hole and releasing the lock on the support plate 72. At this time, the machine housing 5 can be pushed upward to facilitate the removal of the machine housing 5. When the casing 5 is being cut, and when the cutting machine 3 is started and revolving, centrifugal force is generated. The vibration generated during cutting will drive the two sliders 85 to slide on the arc-shaped slide bar 83, and the spring force of the spring 84 will promote the swaying of the sliders 85. The sliders 85 push the protective plate 81 to swing around the pin shaft through the L-shaped push rod 86, providing protection for the cutting operation.
