Description

Technical Field

[0001] The invention belongs to the technical field of new energy vehicles, and specifically relates to a motor shaft detection device for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] After the preparation of the automotive motor shaft, a simple scanning test is required to initially screen out the shafts with large deformation or defects and re-melt them for recycling. However, when manually sorting the shafts, due to their large mass, the manual picking cost is high and it is impossible to work continuously for a long time, so improvements are needed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: a new energy vehicle motor shaft detection device, comprising a fixed base, a transfer device is arranged on the top of the inner wall of the fixed base, a scanning device is evenly arranged on the upper surface of the transfer device, a control device is arranged on the upper part of the transfer device, a supply guide line is arranged on the left side of the transfer device, and a discharge guide line is evenly arranged on the outer surface of the transfer device; The transfer device comprises an axis turntable, the upper surface of the axis turntable is evenly provided with docking sleeves, the top of the inner cavity of the axis turntable is evenly provided with adjustment slots, and the top of the inner cavity of the axis turntable is evenly provided with internal clamping devices through the adjustment slots; The inner clamping device includes a limit rod, and a clamping piece is arranged inside the adjustment slide groove for fixing the limit rod at different positions. The top end of the limit rod is fixedly connected to a guide shaft, and deflection clamps are symmetrically arranged on both sides of the outer surface of the guide shaft. The middle part of the outer surface of the guide shaft is fixedly connected to a controller through a compression tube, and traction rods are symmetrically arranged on both sides of the inner cavity of the controller. A spherical round surface end is arranged at the end position of the traction rod, which is used to be inserted into the inner cavity of the deflection clamp and can rotate with the inner cavity of the deflection clamp.

[0005] Furthermore, the control device includes a fixed top plate, a control motor is fixedly connected to the axis of the lower surface of the fixed top plate, a guide sleeve is fixedly connected to the bottom end of the control motor output shaft, a torsion sleeve is fixedly connected to the outer surface of the control motor output shaft, and thick connecting rods are evenly arranged on the outer surface of the torsion sleeve. When the output shaft of the control motor is twisted, the guide sleeve and the torsion sleeve will be driven to rotate at the same time.

[0006] Furthermore, there are four thick connecting rods, the top of which is fixedly connected to the outer surface of the torsion sleeve, the bottom of which is plugged into the upper surface of the axis turntable through a butt plug, and the outer surface of the guide sleeve is sleeved with the inner wall of the torsion sleeve. There are four inner clamping devices, the bottom of which is plugged into the top of the inner cavity of the axis turntable through an adjustment slot, the outer surface of the deflection clamp is rotatably connected to the outer surface of the guide shaft, and the end of the traction rod away from the controller is rotatably connected to the inner cavity of the deflection clamp through a spherical end.

[0007] Further, the fixed base includes a bottom guide cylinder, a sliding circular plate is provided in the middle of the inner wall of the bottom guide cylinder, a limiting top sleeve is fixedly connected at the axis center of the upper surface of the sliding circular plate, and a docking protrusion is evenly provided on the upper surface of the upper surface of the sliding circular plate. Elastic inner pads are symmetrically fixed on the upper and lower sides of the inner wall of the sliding circular plate, the outer surface of the elastic inner pad is fixedly connected to the middle of the outer surface of the bottom guide cylinder on the side away from the inner wall of the sliding circular plate, and a convex portion similar to the docking protrusion is provided on the lower surface of the axis rotating disk, which is staggered with the docking protrusion. The inner wall of the limiting top sleeve is plugged into the axis center of the lower surface of the axis rotating disk. After the sliding circular plate compresses the elastic inner pad, the elastic inner pad will have elastic potential energy, so that the sliding circular plate shakes in the vertical plane. The side of the axis rotating disk is rotatably connected to the upper part of the inner wall of the bottom guide cylinder, the lower surface of the axis rotating disk is mutually squeezed with the upper surface of the sliding circular plate through the docking protrusion, and the side of the sliding circular plate is slidably connected to the inner wall of the bottom guide cylinder.

[0008] Furthermore, the scanning device comprises a protective top shell, the top of the inner wall of the protective top shell is fixedly connected to a wall-attached inner plate, the bottom of the inner cavity of the wall-attached inner plate is evenly provided with scanning lenses, the side of the inner cavity of the wall-attached inner plate close to the control device is fixedly connected to a transmission wire, and the top of the transmission wire is fixedly connected to a signal terminal. The number of the scanning devices is four, the lower surface of the protective top shell is fixedly connected to the upper surface of the axis turntable, the outer surface of the transmission wire is fixedly connected to the inner wall of the guide sleeve through the guide inner groove, and the top of the transmission wire extends to the outside of the guide sleeve.

[0009] The beneficial effects of the present invention are as follows: 1. The device can transfer the rotating shaft transported to the interior through the transfer equipment, and scan and sort the rotating shaft through the built-in scanning equipment during the transfer, thereby replacing manual sorting work and achieving the effect of improving work efficiency. Due to the large mass of the rotating shaft, during the rotation of the axis turntable, the rotating shaft may be thrown out from the upper surface of the axis turntable due to the large centrifugal force, resulting in the problem of the rotating shaft flying out and injuring people. Therefore, an internal clamping device is set inside to ensure the stability of the rotating shaft during transportation, and to cooperate with the deep rotating shaft to be pushed outward for subsequent transportation of the rotating shaft.

[0010] 2. The device can synchronously scan the internal rotating shaft during the transfer of the axis turntable. Since the scanning device and the rotating shaft are scanned one-to-one, and the rotating shaft will remain relatively static with the scanning device under the restriction of the internal clamping device, the detection result of the scanning device is more stable and reliable. The unqualified rotating shafts are sorted out through the discharge guide lines on the front and rear sides, and the qualified rotating shafts are sorted out through the discharge guide line on the right side, which can prevent the rotating shafts of uneven quality from mixing together, thereby completing the effective sorting of the rotating shafts and preventing the rotating shafts from mixing again after sorting.

[0011] 3. When the axis turntable is rotating and the protective top shell is about to dock with the end of the guide line, the sliding circular plate located below reciprocates and strikes the upper surface of the axis turntable through the docking protrusion, and the axis turntable is always in the center position by limiting the top sleeve. At this time, the axis turntable will vibrate continuously due to the impact force, making it easier for the rotating shaft on the upper surface to roll into the guide line to realize discharge, thereby avoiding the problem that when the internal clamping device pushes the rotating shaft to the end position of the discharge guide line, the rotating shaft stagnates at the top of the discharge guide line and cannot slide down smoothly, causing the rotating shaft to block the discharge guide line.

[0012] 4. The wall-attached inner plate will transmit the data detected by the scanning lens to the axis turntable through the end at the top of the transmission wire, and then the axis turntable controls the inner clamping device on the corresponding side to push the shaft into the corresponding guide line. Therefore, the axis turntable does not rotate continuously, but cyclically rotates in a quarter-turn period. Therefore, when the axis turntable rotates, the overall speed of the axis turntable is relatively slow, and the thick connecting rod will not be deformed due to the large torque force borne by continuous rotation, thereby ensuring reliability and safety during operation.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a new energy vehicle motor shaft detection device, comprising a fixed base 1, a transfer device 2 is arranged on the top of the inner wall of the fixed base 1, a scanning device 4 is evenly arranged on the upper surface of the transfer device 2, a control device 3 is arranged on the upper part of the transfer device 2, a supply guide line 5 is arranged on the left side of the transfer device 2, and a discharge guide line 6 is evenly arranged on the outer surface of the transfer device 2; The transfer device 2 includes an axis turntable 21, the upper surface of which is evenly provided with docking sleeves 23, the top of the inner cavity of the axis turntable 21 is evenly provided with adjustment slots 22, and the top of the inner cavity of the axis turntable 21 is evenly provided with inner clamping devices 7 through the adjustment slots 22; The inner clamping device 7 includes a limit rod 71, and a clamping member is arranged inside the adjusting slide groove 22 for fixing the limit rod 71 at different positions. The top end of the limit rod 71 is fixedly connected to a guide shaft 72, and deflection clamps 73 are symmetrically arranged on both sides of the outer surface of the guide shaft 72. The middle part of the outer surface of the guide shaft 72 is fixedly connected to a controller 74 through a compression tube, and traction rods 75 are symmetrically arranged on both sides of the inner cavity of the controller 74. A spherical round surface end is arranged at the end position of the traction rod 75, which is used to be inserted into the inner cavity of the deflection clamp 73 and can rotate with the inner cavity of the deflection clamp 73.

[0016] The control device 3 includes a fixed top plate 31, a control motor 32 is fixedly connected to the axis center of the lower surface of the fixed top plate 31, a guide sleeve 35 is fixedly connected to the bottom end of the output shaft of the control motor 32, a torsion sleeve 33 is fixedly connected to the outer surface of the output shaft of the control motor 32, and thick connecting rods 34 are evenly arranged on the outer surface of the torsion sleeve 33. When the output shaft of the control motor 32 is twisted, the guide sleeve 35 and the torsion sleeve 33 will be driven to rotate at the same time.

[0017] There are four thick connecting rods 34, the top of which is fixedly connected to the outer surface of the torsion sleeve 33, the bottom of which is plugged into the upper surface of the shaft center turntable 21 through the docking sleeve 23, and the outer surface of the guide sleeve 35 is sleeved with the inner wall of the torsion sleeve 33. There are four inner clamping devices 7, the bottom of the limit rod 71 is plugged into the top of the inner cavity of the shaft center turntable 21 through the adjustment slot 22, the outer surface of the deflection clamping plate 73 is rotatably connected to the outer surface of the guide shaft 72, and the end of the traction rod 75 away from the controller 74 is rotatably connected to the inner cavity of the deflection clamping plate 73 through a spherical end.

[0018] When the device is used to transfer the motor shaft, the shaft is transported to the rightmost scanning device 4 through the supply guide line 5 on the left, and the horizontally inserted shaft is clamped through the internal clamping device 7, that is, the controller 74 contracts the traction rods 75 on both sides, and then the traction rods 75 drive the deflection clamps 73 on both sides to clamp to the side close to the bearing. At this time, the transfer shaft is set inside the leftmost transfer device 2, and then the top control device 3 is started, and the axis turntable 21 is rotated clockwise to transfer the internal clamping device 7 in the front position to the leftmost position. The shaft is transferred through the continuous rotation of the axis turntable 21.

[0019] When the shaft has quality problems after being detected by the scanning device 4, during the process of the axis turntable 21 rotating to the discharge guide lines 6 on the front and rear sides, the internal clamping device 7 will loosen the deflection clamping plate 73, and at the same time, the axis turntable 21 pushes the limit rod 71 to push the internal shaft outward, thereby pushing the shaft to the discharge guide lines 6 on the front and rear sides, and screening out the shafts with quality problems. Then the axis turntable 21 pulls the limit rod 71 back to the initial position and resets it, waiting to clamp the next shaft to realize the cycle; when there is no problem with the quality of the shaft, the internal clamping device 7 pushes the shaft through the rightmost discharge guide line 6 to obtain a qualified shaft.

[0020] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of embodiment 1, the fixed base 1 includes a bottom guide cylinder 11, a sliding circular plate 12 is arranged in the middle of the inner wall of the bottom guide cylinder 11, a limiting top sleeve 13 is fixedly connected to the axis center of the upper surface of the sliding circular plate 12, and a docking protrusion 14 is evenly arranged on the upper surface of the upper surface of the sliding circular plate 12. Elastic inner pads 15 are symmetrically fixed to the upper and lower sides of the inner wall of the sliding circular plate 12, and the side of the outer surface of the elastic inner pad 15 away from the inner wall of the sliding circular plate 12 is fixedly connected to the middle of the outer surface of the bottom guide cylinder 11, and a convex portion similar to the docking protrusion 14 is provided on the lower surface of the axis rotating disk 21, which is staggered with the docking protrusion 14, and the inner wall of the limiting top sleeve 13 is plugged into the axis center of the lower surface of the axis rotating disk 21. After the sliding circular plate 12 compresses the elastic inner pad 15, the elastic inner pad 15 will have elastic potential energy, so that the sliding circular plate 12 shakes in the vertical plane. The side of the axial turntable 21 is rotatably connected to the upper part of the inner wall of the bottom guide tube 11 , the lower surface of the axial turntable 21 is pressed against the upper surface of the sliding circular plate 12 through the docking boss 14 , and the side of the sliding circular plate 12 is slidably connected to the inner wall of the bottom guide tube 11 .

[0021] The scanning device 4 includes a protective top shell 41, a wall-attached inner plate 42 is fixedly connected to the top of the inner wall of the protective top shell 41, scanning lenses 43 are evenly arranged at the bottom of the inner cavity of the wall-attached inner plate 42, a transmission wire 44 is fixedly connected to the side of the inner cavity of the wall-attached inner plate 42 close to the control device 3, and a signal terminal is fixedly connected to the top of the transmission wire 44. There are four scanning devices 4, the lower surface of the protective top shell 41 is fixedly connected to the upper surface of the axis turntable 21, the outer surface of the transmission wire 44 is fixedly connected to the inner wall of the guide sleeve 35 through the guide inner groove, and the top of the transmission wire 44 extends to the outside of the guide sleeve 35.

[0022] The control motor 32 at the top drives the axis turntable 21 and the components on the axis turntable 21 to deflect by directly twisting the guide sleeve 35 and the twisting sleeve 33. During the deflection process, the scanning device 4 on each axis turntable 21 scans the clamped rotating shaft through the internal scanning lens 43, so as to judge the quality of each rotating shaft according to the outer surface shape of the rotating shaft.

[0023] When the axial turntable 21 is rotating and the protective top shell 41 is about to dock with the end of the guide line, the sliding circular plate 12 located below will be squeezed with the raised position on the lower surface of the axial turntable 21 through the docking protrusion 14, and then dislocated. At this time, the sliding circular plate 12 first presses the elastic inner pads 15 on both sides due to the squeezing force, and then the elastic inner pads 15 release the elastic force to reset the sliding circular plate 12. The sliding circular plate 12 reciprocates and hits the upper surface of the axial turntable 21 through the docking protrusion 14, and the axial turntable 21 is always in the center position by limiting the top sleeve 13. At this time, the axial turntable 21 will vibrate continuously due to the impact force, so that the rotating shaft on the upper surface is easier to roll into the guide line to achieve discharge.
