DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1: Reference Figure 1-3 A motor sleeve end hole processing device comprises a support frame 1, a movable frame 3 is slidably connected to the support frame 1, a rotating member 2 for driving the motor sleeve to rotate is connected to the support frame 1, an electric telescopic rod 4 for driving the movable frame 3 to move in a vertical direction is connected to the upper end of the support frame 1, a second motor 5 is fixedly connected to the inner bottom end of the movable frame 3, a first gear 6 is fixedly connected to the output end of the second motor 5, a rotating shaft 7 is rotatably connected to both sides of the inner bottom end of the movable frame 3, a second gear 8 is fixedly connected to the upper end of each rotating shaft 7, each second gear 8 is meshed with the first gear 6, and the bottom end of each rotating shaft 7 passes through the movable frame 3 and is fixedly connected to a drill bit 9; Reference Figure 2 The rotating member 2 includes a first motor 21, which is fixedly connected to the support frame 1. The output end of the first motor 21 is fixedly connected to a support plate 22. Both sides of the upper end of the support plate 22 are fixedly connected to mounting plates 23. A bidirectional screw 24 is rotatably connected between the two mounting plates 23. A handle is fixedly connected to the bidirectional screw 24. The upper end of the support plate 22 is slidably connected to two symmetrically arranged clamping members, each of which is provided with a threaded hole, and each threaded hole is matched with the bidirectional screw 24. Reference Figure 2 The clamping member includes a movable plate 25, one end of which is slidably connected to the upper end of the support plate 22, a threaded hole is provided on the movable plate 25, a limiting plate 26 is fixedly connected to the movable plate 25, and a protruding head 27 is fixedly connected to the upper end of the movable plate 25, one end of which is an arc structure.

[0018] Working principle: The handle drives the bidirectional screw 24 to rotate. After the bidirectional screw 24 rotates, the two movable plates 25 move toward each other. Each movable plate 25 drives the raised head 27 to move. The distance between the two raised heads 27 is reduced. The motor sleeve passes through the two raised heads 27. The bottom end of the motor sleeve contacts the upper end of the limit plate 26. The limit plate 26 supports and limits the motor sleeve. Then the handle is rotated in the opposite direction. The handle drives the bidirectional screw 24 to rotate. After the bidirectional screw 24 rotates, the two movable plates 25 move back to back. Each movable plate 25 drives the raised head 27 to move. The distance between the two raised heads 27 increases. After the two raised heads 27 move back to back for a distance, they contact and squeeze the inner wall of the motor sleeve. Under the cooperation of the limit plate 26 and the raised head 27, the motor sleeve is clamped and fixed. The motor sleeve fixing speed is fast. After the second motor 5 is powered on and started, it drives the first gear 6 to rotate, and the first gear 6 drives the two second gears 8 to rotate, and each second gear 8 drives the rotating shaft 7 to rotate, and each rotating shaft 7 drives the drill bit 9 to rotate. At the same time, after the electric telescopic rod 4 is started, it drives the movable frame 3 to move downward by a set distance and then reset, and the movable frame 3 drives the rotating shaft 7 to move downward, and the rotating shaft 7 drives the drill bit 9 to move. After the movable frame 3 moves downward for a distance, the bottom ends of the two drill bits 9 contact the two sides of the end of the motor sleeve, and the movable frame 3 continues to move downward. The two rotating drill bits 9 drill holes on the end of the sleeve. Since the two drill bits 9 are symmetrically arranged, both sides of the end of the motor sleeve are processed at the same time, and both drilled holes of the motor sleeve are generated. Vibration, because the two drill bits 9 are symmetrically arranged, the forces generated by the vibrations at the two drill holes on the motor sleeve offset each other, so that the motor sleeve will not deflect due to vibration during the drilling process, thereby improving the stability of the motor sleeve during the drilling process, and then improving the accuracy of the drilling at the end of the motor sleeve, and the movable frame 3 drives the two drill bits 9 to move synchronously in the vertical direction, the two drill bits 9 have the same feed speed, and the two second gears 8 are meshed with the first gear 6. After the first gear 6 rotates, the two second gears 8 have the same rotation speed, so that the drilling speed of the two drill bits 9 is the same, the feed speed of the two drill bits 9 is the same, and the drilling speed is the same, thereby improving the accuracy of the drilling at the end of the motor sleeve; After drilling is completed, the movable frame 3 drives the drill bit 9 to move upward and reset, the first motor 21 drives the support plate 22 to rotate to a set angle, the support plate 22 drives the mounting plate 23 to rotate, the mounting plate 23 drives the bidirectional screw 24 to rotate, the bidirectional screw 24 drives the movable plate 25 to rotate, the movable plate 25 drives the motor sleeve to rotate to a set angle through the limit plate 26 and the raised head 27, and the drilling operation is performed again. The motor drives the sleeve to rotate, and the drilling position of the motor sleeve is changed, so the rotation angle of the sleeve can be accurately controlled.

[0019] Embodiment 2: When two drill bits 9 are synchronously drilling a motor shaft sleeve, the drill bit 9 heats up due to drilling, and some debris is easily adhered to the drill bit 9, resulting in inconsistent drilling accuracy of the two drill bits 9. In order to avoid the drill bit 9 heating up and adhering debris, the coolant is cooled by the coolant. Generally, the coolant is guided to the drill bit 9 by a conduit and released. The drill bit 9 is in a rotating state. After the rotating drill bit 9 contacts the flowing coolant, part of the coolant will splash outward, and the coolant will be scattered on the surface of the shaft sleeve, causing the surface of the shaft sleeve to be dirty. Figure 3-7 and Figure 9-10 As another preferred embodiment of the present invention, on the basis of embodiment 1, an anti-scattering mechanism 10 for preventing liquid splashing is fixedly connected to the support frame 1, and the anti-scattering mechanism 10 includes a mounting frame 101, and the mounting frame 101 is fixedly connected to the support frame 1, and one side of the mounting frame 101 is fixedly connected to two symmetrically arranged open boxes 102, each open box 102 is provided with a coolant, and one side of the interior of each open box 102 is fixedly connected to a first connecting plate 103, and one end of each first connecting plate 103 is fixedly connected to a semicircular ring 104, and each semicircular ring 104 is located directly below the corresponding drill bit 9, An adsorption pad 105 is connected to each semicircular ring 104, and the bottom end of the adsorption pad 105 is in contact with the coolant. An open cylinder 106 is fixedly connected to the mounting frame 101, and a piston 107 is slidably connected to the open cylinder 106. A connecting rod 108 is fixedly connected to the upper end of the piston 107, and one end of the connecting rod 108 is fixedly connected to the movable frame 3. A one-way air intake valve is connected to the bottom end of one side of the open cylinder 106, and a conduit is connected to the bottom end of the open cylinder 106, and one end of the conduit is connected to a connecting pipe 109. Both ends of the connecting pipe 109 are connected to different open boxes 102, and both ends of the connecting pipe 109 are fixedly connected to filters.

[0020] Working principle: When the movable frame 3 drives the drill bit 9 to move downward to drill a hole in the end of the sleeve, the bottom end of the drill bit 9 passes through the end of the sleeve, and the movable frame 3 continues to drive the drill bit 9 to move downward. After moving downward for a distance, the drill bit 9 contacts the adsorption pad 105, and the drill bit 9 continues to move downward. The drill bit 9 contacts the coolant in the open box 102, and the coolant cools the drill bit 9 to prevent debris from adhering to the drill bit 9. The open box 102 limits the coolant. When the rotating drill bit 9 contacts the coolant, the coolant in the open box 102 is in a stationary state. At the same time, under the limit of the open box 102, the coolant will not splash outward, so that the coolant will not be scattered on the sleeve, and the sleeve surface will not be dirty. At the same time, the movable frame 3 moves downward and drives the connecting rod 108 to move downward, and the connecting rod 108 drives the piston 107 to move downward. After the piston 107 moves downward, the gas in the open cylinder 106 is gradually squeezed into the conduit, and the conduit guides the gas into the connecting pipe 109. The connecting pipe 109 disperses and guides the gas into different open boxes 102. The gas is released from the open top of the open box 102, which effectively dissipates the heat of the coolant in the open box 102 and prevents the coolant in the open box 102 from heating up. At the same time, the gas released from the open top flows upward and contacts the drill bit 9, dissipating the heat and cooling the drill bit 9. When the movable frame 3 drives the drill bit 9 to move upward and reset, the drill bit 9 which is gradually separated from the coolant in the open box 102 contacts the adsorption pad 105 in a rotating state, and the adsorption pad 105 adsorbs the coolant remaining on the surface of the drill bit 9, thereby reducing the amount of coolant remaining on the surface of the drill bit 9, so that the coolant will not be thrown out during the upward movement and reset of the drill bit 9, and the coolant will not be scattered on the shaft sleeve, and the surface of the shaft sleeve will not be dirty; When the movable frame 3 moves upward and resets, it drives the connecting rod 108 to move, and the connecting rod 108 drives the piston 107 to move, and the external gas enters the open cylinder 106 through the one-way air inlet valve.

[0021] Embodiment 3: The adsorption pad 105 adsorbs the coolant remaining on the surface of the drill bit 9 to reduce the amount of coolant remaining on the surface of the drill bit 9. Since the adsorption pad 105 is located below the drill bit 9, when the drill bit 9 performs drilling processing on the motor shaft sleeve, the debris generated by the processing falls on the adsorption pad 105. When the drill bit 9 contacts the adsorption pad 105, it is easy to cause the debris on the adsorption pad 105 to entangle with the drill bit 9. Figure 4-8 and Fig.10 As another preferred embodiment of the present invention, on the basis of Embodiment 2, each open box 102 is connected with a blocking mechanism 11 for preventing debris from falling on the adsorption pad 105, the blocking mechanism 11 comprises a baffle 111, the baffle 111 is slidably plugged into the open opening of the open box 102, the baffle 111 is located above the adsorption pad 105, the upper end of the baffle 111 is an arc-shaped surface, one end of the baffle 111 is fixedly connected to a second connecting plate 112, the bottom end of the second connecting plate 112 is fixedly connected to a spring 113, one end of the spring 113 is fixedly connected to the open box 102, the second connecting plate 112 is provided with a strip hole 114, one side of the strip hole 114 is provided with an inclined surface, the bottom end of the movable frame 3 is fixedly connected to a third connecting plate 115, the bottom end of the third connecting plate 115 is fixedly connected to a wedge 116, the wedge 116 cooperates with the inclined surface.

[0022] Working principle: Initially, the baffle 111 is located above the adsorption pad 105, and the movable frame 3 drives the drill bit 9 to move downward. After the drill bit 9 moves downward for a distance, it contacts the upper end of the sleeve end. At the same time, the movable frame 3 also drives the third connecting plate 115 to move downward, and the third connecting plate 115 drives the wedge block 116 to move downward. When the drill bit 9 drills a hole in the sleeve end, the wedge block 116 does not contact the inclined surface. After the bottom end of the drill bit 9 passes through the sleeve end, the wedge block 116 contacts the inclined surface, and the debris generated by the drilling falls on the baffle 111. Since the upper end of the baffle 111 is an arc-shaped surface, the debris on the upper end of the baffle 111 slides from both sides into the open box 102. The baffle 111 blocks the debris to prevent it from falling on the adsorption pad 105, thereby preventing the debris on the adsorption pad 105 from winding around the drill bit 9. The movable frame 3 continues to drive the drill bit 9 to move downward, and the movable frame 3 also drives the third connecting plate 115 to move. The third connecting plate 115 drives the wedge block 116 to move downward. The wedge block 116 moves downward to cooperate with the inclined surface. The wedge block 116 continues to move downward and pushes the second connecting plate 112 to move away from the open box 102. After the second connecting plate 112 moves, it pulls the spring 113. The spring 113 generates elastic force after being pulled. The second connecting plate 112 also drives the baffle 111 to move. After the baffle 111 moves, it is misaligned with the adsorption pad 105, so that the baffle 111 will not contact the drill bit 9 moving downward. After the drill bit 9 moves downward for a distance, it passes through the adsorption pad 105 and contacts the coolant in the open box 102. When the drill bit 9 moves upward and resets after cooling, the movable frame 3 drives the third connecting plate 115 to move upward and reset, the third connecting plate 115 drives the wedge block 116 to move, the wedge block 116 moves upward and separates from the inclined surface, the second connecting plate 112 moves and resets under the elastic force of the spring 113, the second connecting plate 112 drives the baffle 111 to move and reset, the baffle 111 is located above the adsorption pad 105 to prevent debris from falling on the adsorption pad 105 during drilling.
