A sleeve 2 10 is fixedly installed on each of the two hanging frames 9. A cylinder 2 11 is fixedly installed in each of the two sleeves 2 10. An L-shaped bracket 12 and an L-shaped bracket 2 13 are fixedly installed on the output rods of the two cylinders 2 11 respectively. The L-shaped bracket 12 is provided with a hole opening mechanism for opening holes in the motor housing. The L-shaped bracket 2 13 is provided with a drilling and grinding mechanism for grinding the holes in the motor housing. The drilling and grinding mechanism includes an inner diameter grinding sheet 45, an inner side grinding sheet 59a and an outer side grinding sheet 59b. The inner diameter grinding sheet 45 is used for the inner wall of the hole, the inner side grinding sheet 59a is used for grinding the surface where the inner side of the motor housing and the hole are connected, and the outer side grinding sheet 59b is used for grinding the surface where the outer side of the motor housing and the hole are connected.

[0038] In this embodiment, when this scheme is used, the motor housing to be processed is first placed on the placement base plate 3, and the upper pressure plate 7 is driven downward by the cylinder 1 6 to fix the motor housing (the motor housing does not carry a tail cover, only an end cover); then, the lifting frame 9 is driven by the transverse movement mechanism to move along the guide plate 8, and the L-shaped bracket 1 12 and the L-shaped bracket 2 13 are moved to the processing position respectively; the opening mechanism on the L-shaped bracket 12 drills the motor housing, and adjusts the direction of the motor housing after drilling, and the drilling and grinding mechanism on the L-shaped bracket 2 13 grinds the bore; the drilling and grinding mechanism grinds the inner wall of the bore through the inner diameter grinding disc 45, and at the same time uses the inner grinding disc 59a and the outer grinding disc 59b to grind the inner and outer surfaces of the motor housing connected to the bore, respectively, to achieve all-round processing of the bore edge;

[0039] The present invention significantly improves the efficiency of motor casing processing by integrating the functions of drilling and grinding. Traditional processing methods require the use of drilling equipment and grinding equipment separately, while the present invention can complete drilling and grinding with a single device, reducing equipment investment and processing time. In addition, the design of the drilling and grinding mechanism allows for more comprehensive grinding of the inner wall and edge of the drilled hole, avoiding the problem of inadequate edge processing in traditional grinding methods and improving processing quality. At the same time, the cooperation of the cylinder and the traverse mechanism realizes the automation of the processing process, reducing the complexity and labor intensity of manual operation.

[0040] In summary, this solution effectively solves the problems of low motor casing processing efficiency and incomplete edge processing in the existing technology through structural design and functional integration; its integrated design not only improves processing accuracy and efficiency, but also reduces production costs, and is suitable for large-scale production and processing of motor casings.

[0043] When in use, the motor housing is fixed on the placement base plate 3, and the lifting frame 9 is driven to move by the transverse movement mechanism, so that the hole-making mechanism on the L-shaped bracket 12 is moved to the processing position; then, the hole-making motor 14 is started, driving the drill bit 15 to rotate, and the lifting frame 9 is gradually moved during this process. After the drilling is completed, the hole-making mechanism returns to its original position and waits for the next processing;

[0044] This solution realizes the automation and efficiency of drilling processing by integrating the hole-making motor 14 and the drill bit 15 on the L-shaped bracket 12; the drill bit 15 is detachable and easy to replace drill bits of different specifications to adapt to drilling processing of different sizes and requirements; at the same time, the drilling mechanism and the grinding mechanism are independently set, avoiding mutual interference during the processing and improving the processing accuracy and stability.

[0046] In this embodiment, when the drilling and grinding mechanism is in use, the motor housing is fixed to the base plate 3. The traverse mechanism drives the hoisting frame 9 to move, causing the drilling and grinding mechanism on the L-shaped bracket 2 13 to move to the processing position. Subsequently, the grinding motor 17 is activated, driving the grinding head to rotate. The inner diameter grinding disc 45 grinds the inner wall of the drilled hole, while the inner grinding disc 59a and the outer grinding disc 59b grind the inner and outer surfaces of the motor housing, respectively, where they connect to the drilled hole.

[0047] This solution achieves simultaneous grinding of the inner wall and edges of the drilled hole by integrating the grinding motor 17, the grinding head, and the eccentric adjustment rotary mechanism on the U-shaped bracket 16, significantly improving processing efficiency and quality. The combined design of the inner diameter grinding disc 45, the inner side grinding disc 59a, and the outer side grinding disc 59b can simultaneously fully grind the inner wall of the drilled hole and the inner and outer connecting surfaces of the motor housing, avoiding the problem of inadequate edge processing in traditional equipment.

By turning the adjustment screw 41, the position of the support block 40 within the adjustment opening 38 and the clearance opening 39 can be adjusted, thereby varying the eccentricity of the U-shaped bracket 16 to accommodate the drilling and grinding requirements of motor housings with varying apertures. Once adjusted, the support block 40 rotates synchronously with the connecting block 34 and driven gear 35, ensuring stability and consistency during the grinding process.

[0059] This solution utilizes an eccentric adjustment rotary mechanism to adjust the eccentric position of the U-shaped bracket 16, enabling the equipment to adapt to drilling and grinding motor casings of varying apertures, improving its versatility and machining accuracy. The coordinated design of the support ring 33, connecting block 34, and driven gear 35 ensures smooth transmission of rotational motion. The introduction of the adjustment screw 41 facilitates more convenient and precise adjustment of the eccentricity. This structure not only improves grinding quality and efficiency but also reduces the complexity of equipment adjustment and maintenance, making it suitable for the efficient machining of motor casings of various specifications.

[0060] In a further preferred embodiment of the present invention, the top of the placement base plate 3 and the bottom of the upper pressing plate 7 both have anti-slip patterns, and the placement base plate 3 and the upper pressing plate 7 are vertically arranged to correspond to each other.

[0061] In this embodiment, the motor housing is placed on the placement base plate 3. Cylinder 1 (6) drives the upper pressure plate 7 downward, cooperating with the placement base plate 3 to clamp the motor housing. The anti-slip pattern increases the friction between the placement base plate 3 and the motor housing, and between the upper pressure plate 7 and the motor housing, effectively preventing the motor housing from slipping or rotating during processing.

[0062] In a further preferred embodiment of the present invention, the independent control box 23 has a built-in battery and a control module, the control module includes a remote signal receiving module, and the remote signal receiving module is equipped with a remote controller.

[0063] In this embodiment, when in use, the operator can send a control signal through the remote controller. After receiving the signal, the remote signal receiving module in the independent control box 23 transmits it to the control module. The control module controls the start and stop and speed adjustment of the grinding motor 17 according to the signal instructions, thereby realizing remote wireless control of the grinding process; by configuring the independent control box 23 with a built-in battery, a control module and a remote controller, wireless remote control of the grinding motor 17 is realized, so that the operator can control the equipment from a certain distance, thereby improving the convenience and safety of operation.

[0064] The following is a detailed description of the connection and control methods between the remote signal receiving module and the remote controller:

[0065] The connection method is as follows:

[0066] Wireless communication connection: The remote signal receiving module and the remote controller are usually connected by wireless communication methods such as radio waves, infrared, Bluetooth, Wi-Fi, Zigbee, or 5G networks. For example, in some home appliance remote controllers, the remote controller and infrared remote controller are wirelessly connected using the Zigbee communication protocol.

[0067] Network connection: The remote control can connect to the remote signal receiving module through a network, such as a Wi-Fi router, to transmit remote control signals. In some industrial control scenarios, the remote control connects to the receiving server via a 5G network to transmit control signals.

[0068] The control method is as follows:

[0069] Infrared remote control: A remote controller transmits infrared signals, which are received and decoded by a remote signal receiving module to control the device. For example, in some high-definition signal transmission systems, an infrared remote control receiver receives the remote control signal and transmits it via a coaxial cable to a remote control transmitter, enabling remote device control.

[0070] Radio wave control: A remote control transmits radio wave signals, which are then received and processed by a remote signal receiving module to control the device. For example, in some computer remote startup and shutdown devices, the remote control signal receiving module connects wirelessly to the remote computer's power control execution module to achieve remote control.

[0071] Network control: The remote controller sends control commands through the network, and the remote signal receiving module controls the device after receiving the commands.

[0072] Bluetooth control: The remote controller pairs with the remote signal receiving module via Bluetooth technology, sending control signals to operate the device. This method is often used in short-range wireless control scenarios, such as controlling smart home devices.

[0073] In a further preferred embodiment of the present invention, the inner diameter grinding plate 45 is located on either side of the grinding rod 32, and the inner grinding plate 59a and the outer grinding plate 59b are located on either side of the grinding rod 32 staggered from the inner diameter grinding plate 45, and the inner grinding plate 59a and the outer grinding plate 59b are arranged correspondingly.

[0074] In this embodiment, during use, the grinding motor 17 drives the grinding rod 32 to rotate, causing the inner diameter grinding disc 45 to grind the inner wall of the drilled hole. Simultaneously, the inner and outer grinding discs 59a and 59b grind the inner and outer surfaces of the motor housing, respectively, where they meet the drilled hole. Because the inner and outer grinding discs 59a and 59b are staggered and arranged in a corresponding manner relative to the inner diameter grinding disc 45, they can effectively grind the inner and outer edges of the drilled hole simultaneously, ensuring the smoothness and consistency of the drilled hole edge.

[0075] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments:

[0076] In another embodiment of the present invention, the end of the grinding rod 32 away from the shaft column 30 is arranged in the direction of the base plate 3 and the drill bit 15, and this end is the insertion end. The insertion end of the grinding rod 32 is provided with an assembly opening 42, and one side of the grinding rod 32 is provided with a track groove 43 connected to the assembly opening 42, and a track bar 44 is inserted into the track groove 43. The track bar 44 is pulled out or inserted along the insertion end direction of the grinding rod 32 through the assembly opening 42, and the side of the track bar 44 extends to the outside of the grinding rod 32, and the inner diameter grinding plate 45 is fixedly installed on the side of the track bar 44 outside the grinding rod 32, and a locking groove 46 is provided on the inner wall of the track groove 43 on the side away from the assembly opening 42, and a locking bar 47 fixedly connected to the track bar 44 is inserted into the locking groove 46. The locking bar 47 is pulled out or inserted following the track bar 44, and the grinding rod 32 and the locking bar 47 are fixed with a locking bolt 48.

[0077] In this embodiment, when the inner diameter grinding sheet 45 needs to be replaced, the locking bolt 48 is loosened, and the track bar 44 and locking bar 47 are pulled out of the assembly opening 42 and the locking slot 46. The inner diameter grinding sheet 45 can then be removed for replacement. After replacement, the track bar 44 and locking bar 47 are reinserted into the track slot 43 and the locking slot 46, and the locking bolt 48 is tightened to complete the installation. The design of the track bar 44 and locking bar 47 facilitates the installation and removal of the inner diameter grinding sheet 45 while ensuring stability after installation.

[0078] This solution achieves rapid replacement of the inner diameter grinding disc 45 through the cooperation of the track bar 44 and the locking bar 47, thereby improving the maintenance efficiency of the equipment. The fixing method of the locking bolt 48 ensures the firmness of the inner diameter grinding disc 45 during use, avoiding uneven grinding or equipment damage caused by loosening.

[0079] In another embodiment of the present invention, a movable block 49 is rotatably installed in the assembly port 42. The setting of the movable block 49 avoids the insertion and extraction path of the track bar 44. Threaded columns 50 are movably installed on both sides of the assembly port 42. The two threaded columns 50 are respectively fixedly connected to the two sides of the movable block 49. The two threaded columns 50 are threadedly sleeved with fastening nuts 51. The two fastening nuts 51 are respectively located on both sides of the grinding rod 32. When the two fastening nuts 51 are tightened, the angle of the movable block 49 is positioned. The movable block 49 is fixedly installed with a connecting piece 52 using a connecting bolt 53. The inner grinding sheet 59a is installed on the connecting piece 52. When inserted, adjust the angle of the movable block 49 so that the inner grinding sheet 59a and the grinding rod 32 are located in the same straight line. When grinding, adjust the angle of the movable block 49 so that the inner grinding sheet 59a is perpendicular to the grinding rod 32. The sliding sleeve on the grinding rod 32 is provided with a displacement sleeve 54, and the outer grinding sheet 59b is installed on the displacement sleeve 54. The outer grinding sheet 59b is perpendicular to the grinding rod 32. When the displacement sleeve 54 slides along the grinding rod 32, it adjusts the distance between the inner grinding sheet 59a and the outer grinding sheet 59b to adapt to the thickness of the motor housing.

[0080] In this embodiment, during use, the sliding displacement sleeve 54 adjusts the spacing between the inner grinding sheet 59a and the outer grinding sheet 59b according to the thickness of the motor housing to adapt to the thickness of the motor housing. During insertion, the angle of the movable block 49 is adjusted so that the inner grinding sheet 59a and the grinding rod 32 are aligned, facilitating insertion into the drilled hole of the motor housing. During grinding, the angle of the movable block 49 is adjusted again so that the inner grinding sheet 59a is perpendicular to the grinding rod 32 and cooperates with the outer grinding sheet 59b to grind the inner and outer surfaces of the motor housing that connect to the drilled hole. By screwing the fastening nut 51, the angle of the movable block 49 can be fixed, ensuring stability during the grinding process and ensuring that the inner diameter grinding sheet 45 is in contact with the inner wall of one side of the drilled hole.

[0081] In another embodiment of the present invention, rectangular guide columns 55 are fixedly installed on the top of the connecting plate 52 and the displacement sleeve 54, and connecting sleeves 56 are slidably sleeved on the two rectangular guide columns 55. Positioning bolts 57 are threadedly installed on the two connecting sleeves 56. The ends of the positioning bolts 57 are in conflict with the rectangular guide columns 55 and are used to position the height of the connecting sleeves 56. Hard plates 58 are fixedly installed on the two connecting sleeves 56, and the two hard plates 58 are fixedly connected to the inner grinding plate 59a and the outer grinding plate 59b, respectively.

[0082] In this embodiment, during use, the sliding connection sleeve 56 is adjusted on the rectangular guide post 55 according to the thickness of the motor housing and the diameter of the drilled hole. This adjusts the height of the inner and outer grinding discs 59a and 59b, aligning the grinding discs with the edges of the drilled hole in the motor housing. Once adjusted, the positioning bolts 57 are tightened until their ends contact the rectangular guide post 55, securing the position of the connection sleeve 56 and ensuring the stability of the grinding discs during the grinding process. The hard plate 58 provides stable support for the grinding discs, ensuring a good grinding effect.

[0083] This solution achieves flexible adjustment of the height of the inner grinding sheet 59a and the outer grinding sheet 59b through the cooperation of the rectangular guide column 55 and the connecting sleeve 56, which can adapt to the grinding requirements of motor casings with different thicknesses and drilling diameters.

[0084] In another embodiment of the present invention, a displacement groove 60 and an operating groove 62 are provided on the grinding rod 32, and a displacement block 61 is slidably installed in the displacement groove 60. The displacement block 61 is fixedly connected to the displacement sleeve 54, and an adjusting screw 63 is rotatably installed on the inner wall between the displacement groove 60 and the operating groove 62. The threaded section of the adjusting screw 63 is located in the displacement groove 60 and threadedly penetrates the displacement block 61, which is used to control the sliding of the displacement block 61 and the displacement sleeve 54, thereby adjusting the position of the outer grinding plate 59b. One end of the adjusting screw 63 is located in the operating groove 62 and is fixedly installed with a knob 64.

[0085] In this embodiment, during use, the operator rotates the knob 64 to rotate the control screw 63, which in turn drives the displacement block 61 to slide within the displacement slot 60. The displacement block 61 drives the displacement sleeve 54 along the grinding rod 32, thereby adjusting the position of the outer grinding sheet 59b to accommodate motor casings of varying thicknesses. After adjustment is achieved, the knob 64 is stopped. The threaded connection between the control screw 63 and the displacement block 61 has a self-locking function, which can maintain the position of the displacement sleeve 54 and ensure the stability of the outer grinding sheet 59b during the grinding process.

[0086] This solution achieves precise adjustment of the position of the outer grinding sheet 59b by adjusting the cooperation between the screw 63 and the displacement block 61, and can adapt to the grinding requirements of motor casings of different thicknesses.

[0087] In another embodiment of the present invention, a slide groove 65 is further provided on the grinding rod 32, and the slide groove 65 is communicated with the inner wall of the operating groove 62 on the side away from the displacement groove 60. An L-shaped handle 66 is slidably installed in the slide groove 65, and one end of the L-shaped handle 66 extends into the operating groove 62, and the other end extends to the outside of the grinding rod 32. A spring 67 is provided in the slide groove 65, and the two ends of the spring 67 are fixedly connected to the inner wall of the slide groove 65 and the L-shaped handle 66 respectively. The knob 64 is located at one end of the L-shaped handle 66 and is provided with a spline groove 68. The end of the L-shaped handle 66 located in the operating groove 62 is fixedly installed with a spline rod 69, and the spline rod 69 is inserted into the spline groove 68 to stabilize the knob 64 and the regulating screw 63.

[0088] In this embodiment, during use, the operator pulls the L-shaped handle 66, causing it to slide outward along the slide groove 65. This compresses the spring 67, and the spline rod 69 is withdrawn from the spline groove 68. The operator can then rotate the knob 64 to adjust the position of the outer grinding sheet 59b via the adjusting screw 63. After adjustment, the L-shaped handle 66 is released, and the spring 67 returns to its original position, driving the L-shaped handle 66 back, reinserting the spline rod 69 into the spline groove 68. This locks the knob 64 and adjusting screw 63, preventing them from rotating during the grinding process and ensuring the stability of the outer grinding sheet 59b.

[0089] To sum up, compared with the relevant technology, the drilling and grinding mechanism of this device grinds the inner wall of the drilled hole through the inner diameter grinding plate 45, and at the same time uses the inner grinding plate 59a and the outer grinding plate 59b to grind the inner and outer surfaces of the motor housing connected to the drilled hole respectively, thereby achieving all-round processing of the drilled hole edge.
