Technical Field

[0001] This application relates to the technical field of drilling equipment, and in particular to an end cap processing device. Background Technology

[0002] Motor end caps refer to the protective covers installed at both ends of the motor housing. They are mainly used to determine the axial spatial position of the rotor and to cooperate with different types of bearings.

[0003] Reference Figure 1 The motor end cover body 01 has multiple mounting holes 011 evenly distributed around its outer periphery along its axis. The mounting holes 011 are used for bolts to pass through and connect to the wheel hub via threads, thereby achieving a fixed connection between the motor end cover body 01 and the wheel hub. The outer periphery of the motor end cover body 01 is provided with an indicator groove 012 for assisting in the installation of the motor end cover body 01. One end of the motor end cover body 01 is coaxially connected to a boss 013. The end face of the boss 013 is provided with multiple threaded holes 0131 evenly distributed around its axis for mounting disc brake pads.

[0004] After the motor end cover body 01 is manufactured, in order to meet its installation requirements, it is necessary to drill holes at the boss 013 to realize the machining of threaded holes 0131.

[0005] In related technologies, the motor end cover body is typically fixed below the drill bit of a drilling machine. The drilling machine is then controlled to move up and down, and the high-speed rotating drill bit drills a hole in a designated area of ​​the motor end cover body. After drilling is complete, the drilled motor end cover body is removed and placed on a tapping device for thread inspection. However, because replacing the motor end cover body, drilling, and tapping must be performed alternately, time is wasted and production efficiency is affected. Utility Model Content

[0006] In order to simultaneously perform the replacement of motor end caps, drilling and tapping operations, and improve production efficiency, this application provides an end cap processing device.

[0007] The end cap processing device provided in this application adopts the following technical solution: An end cap processing device includes a frame, a turntable, a mounting base, a drilling mechanism, and a tapping mechanism. The turntable is coaxially rotatably connected to the frame. The mounting base is connected to one side of the turntable along its rotation axis. Several mounting bases are provided and are evenly distributed circumferentially around the rotation axis of the turntable. The side of the mounting base away from the turntable is used to place a motor end cap body. The drilling mechanism and the tapping mechanism are both connected to the frame. The drilling mechanism is used to drill holes in the motor end cap body placed on the mounting base, and the tapping mechanism is used to tap the motor end cap body placed on the mounting base.

[0008] By adopting the above technical solution, the completed motor end cover body is removed, and the motor end cover body to be processed is placed on the mounting base. The turntable rotates, driving the mounting base to rotate, and the motor end cover body to be processed is sequentially aligned with the drilling mechanism and the tapping mechanism. After the drilling mechanism drills holes in the motor end cover body, the tapping mechanism taps the corresponding holes, thus simultaneously realizing the replacement of motor end cover, drilling and tapping operations, improving production efficiency.

[0009] Preferably, the mounting base has a clearance groove on its outer periphery, and the clearance groove is located on the side of the mounting base away from the rotation axis of the turntable.

[0010] By adopting the above technical solution, it is easier for workers to embed their palms into the clearance groove and push the completed motor end cover body away from the mounting base, thereby improving production efficiency.

[0011] Preferably, a positioning post is connected to the side of the turntable near the mounting base. The positioning post passes through the clearance groove and is embedded in the mounting hole of the motor end cover body. An indicator block is connected to the side of the mounting base away from the turntable. The indicator block is used to be embedded in the indicator groove of the motor end cover body. The side wall of the indicator block is in contact with the groove wall of the indicator groove of the motor end cover body.

[0012] By adopting the above technical solution, positioning posts and indicator blocks are set to position the motor end cover body placed on the mounting base, so that when the motor end cover body is aligned with the drilling mechanism or tapping mechanism, the theoretical machining position of the threaded hole of the motor end cover body coincides with the actual machining position, thereby improving the positioning accuracy of the drilling mechanism and tapping mechanism.

[0013] Preferably, it also includes a chip removal mechanism, which is connected to the frame and is used to clean the debris at the threaded hole of the motor end cover body. The drilling mechanism, tapping mechanism and chip removal mechanism are arranged in sequence around the rotation axis of the turntable.

One end of the fan shroud is provided with a cavity, which is used to communicate with the threaded hole of the motor end cover body. The air source is connected to the frame and is connected to the cavity through a pipe.

[0016] By adopting the above technical solution, the chip removal drive cylinder drives the air cover to slide close to the motor end cover body, so that the air source introduced into the cavity can accurately act on the motor end cover body, thereby improving cleaning efficiency.

[0017] Preferably, the drilling mechanism includes a drill bit and a drilling slide seat. The drilling slide seat is slidably connected to the frame, and the sliding direction of the drilling slide seat is parallel to the rotation axis of the turntable.

Remove the completed motor end cover body, and then place the motor end cover body to be processed on the mounting base. The turntable rotates, which drives the mounting base to rotate, causing the motor end cover body to be processed to face the drilling mechanism and the tapping mechanism in sequence. After the drilling mechanism drills holes in the motor end cover body, the tapping mechanism taps the corresponding holes. This simultaneously realizes the replacement of motor end cover, drilling and tapping operations, improving production efficiency. 2. A chip removal mechanism is installed to clean the motor end cover body after drilling and tapping, reducing the possibility of processing debris adhering to the motor end cover body and causing workers to be scratched when removing the motor end cover body, thus improving equipment safety. 3. The lubricating oil in the oil tank is delivered to the first oil outlet pipe and the second oil outlet pipe by the oil pump. Then, the oil is sprayed from the first oil outlet to the drill bit and from the second oil outlet to the tap, thereby lubricating the drill bit and the tap, reducing the wear caused to the drill bit and the tap during the drilling and tapping process, and improving the service life of the drill bit and the tap.

[0045] The implementation principle of the end cap processing device in this application embodiment is as follows: the motor end cap body that has been processed on the mounting base 24 located at the processing station is removed, and the motor end cap body to be processed is placed on the mounting base 24, so that the side wall of the limiting post 211 fits against the hole wall of the through hole of the motor end cap body, the indicator block 241 is embedded in the indicator groove of the motor end cap body, and the positioning post 244 is embedded in the mounting hole of the motor end cap body.

[0046] The conveyor drive motor 23 operates, driving the turntable 21 to rotate, which in turn drives the mounting base 24 to rotate, causing the motor end cover body to rotate to the drilling position 122, so that the motor end cover body is directly facing the drill bit 32. The drilling drive motor 34 operates, driving the drill bit 32 to rotate through the first transmission assembly. The piston rod of the drilling drive cylinder 33 retracts, causing the drilling sliding seat 31 to slide closer to the motor end cover body, and driving the drill bit 32 closer to the motor end cover body to perform drilling. After drilling is completed, the piston rod of the drilling drive cylinder 33 extends, causing the drill bit to slide away from the motor end cover body.

[0047] When the conveyor drive motor 23 operates, it drives the turntable 21 to rotate, which in turn drives the mounting base 24 to rotate, causing the motor end cover body to rotate to the tapping station 123, so that the motor end cover body is directly facing the tap 42. Then, the tapping drive motor 44 operates, driving the tap 42 to rotate through the second transmission assembly. The conveyor drive motor 23 operates, driving the turntable 21 to rotate, which in turn drives the mounting base 24 to rotate, causing the motor end cover body to rotate to the chip removal station 124, so that the motor end cover body is facing the air shroud 51. The piston rod of the chip removal drive cylinder 52 extends, causing the air shroud 51 to slide closer to the motor end cover body. The air source 53 introduces outside air into the cavity 511 through a pipe, thereby removing chips from the threaded holes of the motor end cover body. After chip removal is completed, the piston rod of the chip removal drive cylinder 52 retracts, causing the air shroud 51 to slide away from the motor end cover body.

[0048] The conveyor drive motor 23 operates, driving the turntable 21 to rotate, driving the mounting base 24 to rotate, and driving the motor end cover body to rotate to the loading station 121.

[0049] When the first sensor 65 detects the drilling sliding seat 31, it sends a signal to the controller. The controller then controls the first solenoid valve 64 to connect the main pipe 621 and the first oil outlet pipe 622. Lubricating oil is sprayed from the first oil outlet hole 6221 onto the drill bit 32. Excess lubricating oil enters the first oil receiving groove 6111. When the second sensor 67 detects the tapping sliding seat 41, it sends a signal to the controller. The controller then controls the second solenoid valve 66 to connect the main pipe 621 and the second oil outlet pipe 623. Lubricating oil is sprayed from the second oil outlet hole 6231 onto the tap 42. Excess lubricating oil enters the second oil receiving groove 6121. The lubricating oil in the first and second receiving grooves enters the connecting pipe 610 and then falls onto the filter screen 69. After being filtered by the filter screen 69, the lubricating oil enters the receiving cavity 681.
