Description

Technical Field

[0001] The invention relates to the technical field of motor parts 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 in a servo system, and has the characteristics of precise control of speed and position. In the manufacturing process of servo motors, the processing of rotor punching is a key link. In the process of stamping and forming the servo motor rotor punching, it is indeed necessary to compact the punching into a uniform thickness. This is because the thickness uniformity of the motor stator and rotor punching is crucial to the performance and operating stability of the motor. If the thickness of the punching is inconsistent, it may cause vibration, noise, and reduced efficiency during the operation of the motor.

[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, the punched sheets cannot be made thinner in one punching. 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.

The height of the baffle 48 can be intuitively seen through the indication 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 screened punching sheets, thereby meeting the use of punching sheets of different models and sizes. The entire screening mechanism has a high degree of automation and high screening efficiency, and does not require manual operation, which greatly improves the qualified rate of the punching sheets.

[0038] A discharging inclined plate 1 5 is fixed on one side of the box body 2, and a discharging inclined plate 2 6 is fixed on the other side of the box body 2.

[0039] For illustration, although there are differences in 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.

[0043] By setting the feeding component 25 and cooperating with the conveyor belt 9, the automatic re-feeding of over-thick punching sheets is realized, and the over-thick punching sheets are pushed back into the feeding barrel 20 for stacking, so that the over-thick punching sheets can be punched and screened again until the thickness of the punching sheets is qualified, and multiple stamping operations can be performed on unqualified punching sheets without the need for manual feeding operations again, 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.

[0046] The top and bottom of the sliding column 2610 are fixed with a limit strip 2611, and the outer surfaces of the two limit strips 2611 are slidably connected with the inner surface of the limit groove 269. An extension column 2612 is fixed to one end of the sliding column 2610, and 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.

[0048] By setting up the automatic turning unit 26, the overly thick punching sheets on the conveyor belt 9 can be received and turned over, so that the punching sheets can be evenly stamped 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 and fall onto 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 punch is placed into the barrel 20, so that the punches are stacked in the feed barrel 20, the cylinder 13 is started to shrink, the cylinder 13 drives the push plate 14 to move rightward, so that a punch at the bottom falls into the placement slot 16, and the cylinder 13 further pushes the push plate 14 to move leftward, so that the punch is located under the cylinder 21, and the cylinder 21 is started to drive the stamping seat 22 to press and flatten the punch, and the cylinder 13 is further contracted. Under the action of the penetration rod 23, the punch falls onto the support plate 310, and the motor 312 is started. The motor 312 is driven by the punch seat 22 to press and flatten the punch. 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 piece to rotate to the baffle 48, if the thickness of the punching piece is too thick, the punching piece cannot pass through the gap between the baffle 48 and the supporting plate 310, and is blocked by the baffle 48, and falls on the discharge inclined plate 2 6, and further falls on the conveyor belt 9, and the conveyor belt 9 is used for transmission. The qualified punching sheet rotates to the baffle plate 24, is blocked by the baffle plate 24 and falls onto the discharging inclined plate 5, slides into the collecting box 7 for collection, and the baffle plate 48 can be raised and lowered by rotating the screw block 44, thereby controlling the thickness of the punching sheet screening. 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 rotating wheel 263 to rotate, and the push rod 2616 is intermittently pushed out through the cooperation of the convex groove 265 and the Z-shaped groove 264, and after the push rod 2616 is pushed out, the flat plate 2618 and the wedge block 2619 are turned 90 degrees. At the same 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, and further starts 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, and starts the cylinder 3 258, and the cylinder 3 258 drives the loading plate 257 to move, and finally the loading plate 257 pushes the punching sheet with extra thick thickness into the feeding barrel 20, and the stamping and screening operations are performed again until it is qualified.
