Description

Technical Field

[0001] The invention relates to the technical field of motor component processing, in particular to a servo motor rotor punching processing and forming device. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components within a servo system, offering precise speed and position control. The processing of rotor laminations is a critical step in servo motor manufacturing. During the stamping process, the servo motor rotor laminations must be compacted to a uniform thickness. This is because the uniformity of the thickness of the stator and rotor laminations is crucial to the motor's performance and operational stability. Inconsistent lamination thickness can cause vibration, noise, and reduced efficiency during motor operation.

[0003] However, if the silicon steel sheet raw material itself has the problem of uneven thickness, then during the stamping process, the thicker part and the thinner part will be subjected to different pressures and deformation degrees, resulting in inconsistent thickness of the punched sheets. Sometimes, one punching cannot make the punched sheets thinner. The existing stamping equipment cannot automatically screen the thicker punched sheets, and the thicker punched sheets after screening cannot be quickly automatically loaded and then stamped. In this regard, we propose a servo motor rotor punching processing and forming device to solve the above problems. Summary of the Invention

[0014] Beneficial effects

[0015] The present invention provides a servo motor rotor punching and forming device. Compared with the prior art, it has the following advantages:

[0016] (1) Through the setting of the automatic screening mechanism, the unqualified thick punching sheets can be automatically and quickly screened, so that the over-thick punching sheets fall onto the second discharge inclined plate for discharge, and the feeding, punching and screening operations are performed again after discharge. Through the setting of the baffle plate, the qualified punching sheets fall onto the first discharge inclined plate and fall into the collection box for collection. Through the setting of the screening material adjustment component, the height of the baffle can be adjusted. The height of the baffle can be intuitively seen through the number on the scale line.

[0017] (2) Through the setting of the feeding component, in coordination with the conveyor belt, the over-thick punching sheets can be automatically re-loaded, and the over-thick punching sheets can be pushed back into the feeding barrel for stacking, so that the over-thick punching sheets can be punched and screened again until the thickness of the punching sheets is qualified.

The outer surface of the cam 311 contacts and squeezes one side of the sleeve 34. When the cam 311 rotates, one side of the sleeve 34 can be intermittently squeezed. A motor 312 is fixed on one side of the box body 2. The motor 312 is controlled by an external switch and is electrically connected to an external power supply. The motor 312 is a stepping motor that can control the number of rotations and the speed. The motor 312 drives the rotating rod 31 to rotate. A screening and unloading adjustment component 4 for screening and unloading excessively thick punching sheets is provided on one side of the inner wall of the box body 2.

[0035] Through the setting of the automatic screening mechanism 3, it is possible to automatically and quickly screen the thicker unqualified punching sheets, so that the overly thick punching sheets fall onto the discharging inclined plate 2 6 for discharging. After discharging, the feeding, stamping and screening operations are performed again. Through the setting of the baffle plate 24, the qualified punching sheets fall onto the discharging inclined plate 1 5 and fall into the collection box 7 for collection.

[0037] By setting the screening material discharging adjustment component 4, the height of the baffle can be adjusted. The height of the baffle 48 can be intuitively seen through the number on the scale line 47. By adjusting the height of the baffle 48, the size of the gap between the baffle 48 and the support plate 310 can be controlled, thereby controlling the thickness of the screening punching sheet, meeting the use of punching sheets of different models and sizes.

A mounting frame 17 is fixed on the top of the base 1.

[0039] For the purpose of explanation, although there are differences in the thickness of the same batch of punching sheets produced by the same equipment, the range of the thickness difference is small. Therefore, in the present invention, the height of the placement groove 16 can be the same as the height of the punching sheet with the largest thickness difference, so that the placement groove 16 can only accommodate one punching sheet at a time.

[0040] A connecting plate 18 and a connecting plate 2 19 are fixed to one side of the mounting frame 17. A feed barrel 20 is fixed inside the connecting plate 18. Unpunched sheets are stacked in the feed barrel 20. The thickness of the sheets in the feed barrel 20 is randomly stacked. The bottom end of the feed barrel 20 is slidably connected to the top of the push plate 14. A cylinder 21 is fixed between the connecting plate 18 and the connecting plate 2 19. The cylinder 21 is controlled by an external switch and is electrically connected to an external power supply.

[0043] By setting up the loading component 25 and cooperating with the conveyor belt 9, the automatic reloading of over-thick punches is realized, and the over-thick punches are pushed back into the feed barrel 20 for stacking, so that the over-thick punches can be punched and screened again until the thickness of the punches is qualified. Multiple punching operations can be performed on unqualified punches without the need for manual loading operations, which greatly improves work efficiency.

[0044] Example 3

[0045] Based on Example 2, see Figure 9-10 As shown, the interior of the box body 2 is also provided with an automatic turning unit 26 for driving the over-thick punching sheets under screening to be turned over and stacked on the L-shaped receiving plate 255.

The outer surface of the rotating wheel 263 is provided with a Z-shaped groove 264, and a convex groove 265 is provided on one side of the circular plate 262. A fixing seat 266 is fixed on the bottom wall of the box body 2, and a cross seat 267 is fixed on the top of the fixing seat 266. Two through holes 268 are provided on one side of the cross seat 267, and two limit grooves 269 are provided on the upper and lower sides of the inner wall of one of the through holes 268. A sliding column 2610 is slidably connected to the interior of one of the through holes 268.

[0046] The top and bottom of the sliding column 2610 are fixed with a limit strip 2611. The outer surfaces of the two limit strips 2611 are slidably connected to the inner surface of the limit groove 269. An extension column 2612 is fixed to one end of the sliding column 2610. One end of the extension column 2612 extends to the inside of the Z-shaped groove 264, and the extension column 2612 slides inside the Z-shaped groove 264. Through the cooperation of the Z-shaped groove 264 and the extension column 2612, the sliding column 2610 can be reciprocated back and forth. The other through hole 268 is internally rotatably connected to a rotary cylinder 2613, and a rotating arm 2614 is fixed to one end of the rotary cylinder 2613. The protrusion on the rotating arm 2614 is located inside the convex groove 265, and the outer surface of the protrusion is slidably connected to the inner surface of the convex groove 265.

The card plate 2621 is stuck between the limit card wheel 2620. The setting of the card plate 2621 and the limit card wheel 2620 can realize the synchronous sliding of the push rod 2616 and the sliding column 2610. A pulley 2622 is fixed on the driving rod 261 and the rotating rod 31. The two pulleys 2622 are connected by a belt 2623.

[0048] By setting up the automatic turning unit 26, the overly thick punching sheets on the conveyor belt 9 can be connected and turned over, so that the punching sheets can be evenly punched on both sides after being turned over, which greatly reduces the thickness inconsistency caused by the uneven thickness of the silicon steel sheet raw material itself. By setting up the wedge block 2619, the punching sheets can slide on the wedge block 2619 to the L-shaped receiving plate 255 for stacking after being turned over, which is convenient for the subsequent one-time loading operation of the loading plate.

[0049] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0050] During operation, the punching sheet is placed into the barrel 20, so that the punching sheets are stacked in the feed barrel 20, and the cylinder 13 is started to shrink. The cylinder 13 drives the push plate 14 to move to the right, so that the punching sheet at the bottom layer falls into the placement groove 16, and the cylinder 13 further pushes the push plate 14 to move to the left, so that the punching sheet is located under the cylinder 21, and the cylinder 21 is started to drive the stamping seat 22 to press and flatten the punching sheet, and the cylinder 13 is further shrinked. Under the action of the penetrating rod 23, the punching sheet falls onto the support plate 310, and the motor 312 is started. The motor 312 is started and the motor 313 is started. 12 drives the rotating rod 31 to rotate, and the rotation drives the cam 311 to rotate. The cam 311 drives the sleeve 34 to slide in the cylinder 33, and at the same time makes the connecting column 37 slide in the wave groove 36, and at the same time drives the rotating cylinder 35 to rotate intermittently by 90 degrees, thereby driving the four supporting plates 310 to rotate intermittently by 90 degrees. When the supporting plate 310 drives the punching sheet to rotate to the baffle 48, if the punching sheet is too thick, the punching sheet cannot pass through the gap between the baffle 48 and the supporting plate 310, and is blocked by the baffle 48, and falls onto the discharge inclined plate 2 6, and further falls onto the conveyor belt 9, which is transported by the conveyor belt 9. The qualified punches rotate to the baffle plate 24, are blocked by the baffle plate 24 and fall onto the discharge inclined plate 5, slide into the collection box 7 for collection, and are raised and lowered by rotating the screw block 44, thereby controlling the thickness of the punches to be screened. When the motor 312 is started, the driving rod 261 is driven to rotate, and the driving rod 261 drives the circular plate 262 and the runner 263 to rotate. Through the cooperation of the convex groove 265 and the Z-shaped groove 264, the push rod 2616 is intermittently pushed out, and after the push rod 2616 is pushed out, the flat plate 2618 and the wedge block 2619 are turned 90 degrees. At this time, the punching sheet on the conveyor belt 9 falls onto the pushed out flat plate 2618, and then turns over. The punching sheet turns over and falls onto the wedge block 2619, and then slides from the wedge block 2619 to the L-shaped receiving plate 255 for stacking. Further start the motor 254, so that the motor 254 drives the screw rod 253 to rotate, and the screw rod 253 drives the L-shaped receiving plate 255 to move upward, start the cylinder 3 258, and the cylinder 3 258 drives the loading plate 257 to move. Finally, the loading plate 257 pushes the punching sheet with extra thick thickness into the feed barrel 20, and the stamping and screening operations are performed again until it is qualified.
