Description

Technical Field

[0001] This utility model relates to the field of motor shaft processing technology, specifically to an inverted deep hole drilling machine for motor shafts. Background Technology

[0002] As the core transmission component of a motor, the machining accuracy of the motor shaft directly determines the motor's operational stability, transmission efficiency, and service life. Deep hole machining is one of the key processes in motor shaft manufacturing. Due to the characteristics of small diameter, large depth, and high length-to-diameter ratio of deep holes in motor shafts, stringent requirements are placed on the rigidity, positioning accuracy, chip removal capability, and stability of the machining equipment.

[0003] Traditional horizontal deep hole drilling machines are limited by their structural layout when machining motor shafts. In a horizontal layout, the motor shaft workpiece needs to be placed horizontally and fixed. Long shaft workpieces are prone to deflection due to their own weight, which causes the drill rod and the workpiece axis to deviate during the drilling process. This affects the coaxiality and cylindricity of the deep hole, and cannot meet the machining requirements of high-precision motor shafts.

[0004] Chinese Patent Announcement No. CN223235818U provides an inverted drilling machine that facilitates accurate positioning. This solution allows for drilling of workpieces using the inverted drilling machine body, and facilitates the positioning and alignment of the workpiece and drill bit, thereby reducing the workload of operators and improving overall work efficiency.

[0005] However, the following defects still exist in the specific implementation process: the drilling machine lacks an effective chip collection and separation mechanism. If the chips generated during the processing are mixed with the cooling lubricant and cannot be treated in time, they will pollute the working environment. Furthermore, the chips that are not discharged in time will accumulate in the processing area, affecting the processing quality.

[0006] Based on this, this utility model designs an inverted motor shaft deep hole drilling machine to solve the above problems. Utility Model Content

[0018] The present invention will be further described below with reference to the embodiments.

[0019] In some embodiments, please refer to the appendix to the instruction manual. Figure 1 - Figure 5A deep hole drilling machine with an inverted motor shaft includes a support frame 1.

The drilling machine structure 2 includes a support plate 21, which is fixedly installed on the upper end of the support frame 1. A discharge groove 22 is opened on the upper end of the support plate 21. A discharge component 23 is fixedly connected to the upper end of the support plate 21. A collection component 24 is fixedly connected to one side of the support plate 21. A drilling component 25 is fixedly connected to the lower end of the support plate 21.

[0020] The motor 32 is a Panasonic A6 series servo motor, which can provide power for the linear motion of the transmission component 35 and drive the motor shaft to move vertically.

[0021] The discharge assembly 23 includes a trough cover 231, which is fixedly installed on the upper end of the support plate 21. A fan 232 is fixedly connected to one side of the trough cover 231, and a collection hopper 233 is fixedly connected to the upper inner surface of the trough cover 231.

[0022] The blower 232 is a positive pressure blower, which provides airflow for the collection of chips and coolant, and can blow the mixture of metal chips and coolant generated during drilling into the collection box 241.

[0023] The collection assembly 24 includes a collection box 241, which is fixedly installed on one side of the support plate 21. A feed inlet 242 is provided on one side of the collection box 241, and a box cover 243 is hinged to the other side of the collection box 241. An open separation plate 244 is provided in the inner cavity of the collection box 241. A drain pipe 245 is fixedly connected to the lower end of the collection box 241. A solenoid valve 246 is provided on the outer surface of the drain pipe 245. A reinforcing frame 247 is fixedly connected to one side of the collection box 241 and is fixedly installed on the upper end of the support frame 1.

[0024] The solenoid valve 246 is a two-position two-way solenoid valve. When energized, the valve opens, which facilitates the discharge of the separated coolant in the collection box 241 through the drain pipe 245.

[0025] The drilling assembly 25 includes a first reinforcing plate 251. A second motor 252 is fixedly connected to one side of the first reinforcing plate 251. The output end of the second motor 252 is fixedly connected to a sprocket drive structure 253 via a coupling. A drilling machine 254 is fixedly connected inside the sprocket drive structure 253. A drill rod 255 is fixedly connected inside the drilling machine 254. A second reinforcing plate 256 is fixedly connected to one side of the drilling machine 254. Both the first reinforcing plate 251 and the second reinforcing plate 256 are fixedly installed at the lower end of the support plate 21.

[0026] Motor 252 is a Siemens three-phase asynchronous motor, which provides power for the rotation of drill rod 255. Through sprocket drive structure 253, the power can be transmitted to the spindle of drilling machine 254, driving drill rod 255 to rotate at high speed, meeting the cutting power requirements of deep hole drilling with motor shaft. In this embodiment of the invention, by controlling the reverse rotation of the built-in motor of the three-jaw chuck 364, the three jaws can be driven to move outward synchronously, so that the chuck is in an open state. Then, the motor shaft to be processed is placed vertically, so that the lower end of the motor shaft passes through the central through hole of the perforated plate 371 and the upper end extends between the three jaws of the three-jaw chuck 364. At this time, the built-in motor of the three-jaw chuck 364 is controlled to rotate forward, so that the jaws move inward synchronously until they clamp the upper end of the motor shaft. At the same time, the electromagnet 374 is energized to generate magnetic force, which repels the magnetic block 376. Under the action of magnetic force, the magnetic block 376 moves along the slide rail 373 towards the direction close to the motor shaft. At this time, the spring 375 is in a stretched state, so that multiple rubber blocks 378 can be tightly attached to the outer surface of the lower end of the motor shaft, realizing double fixation of the upper and lower ends of the motor shaft and preventing vibration or displacement during processing.

[0027] After the motor shaft is clamped, the control motor 252 is started, driving the drive sprocket to rotate. The drive sprocket drives the driven sprocket to rotate via a chain, which in turn drives the spindle of the drilling machine 254 to rotate. The drill rod 255 connected to the spindle can then rotate synchronously at high speed. At the same time, the control motor 32's servo driver is started, causing the motor 32 to drive the lead screw 34 to rotate. Since the moving block 351 is threadedly engaged with the lead screw 34, and the transmission component 35 is slidably connected to the slide rail 33 via the slider 354, the rotational motion of the lead screw 34 is converted into the linear motion of the moving block 351. This causes the connecting plate 352, mounting plate 353, fixing component 36, and stabilizing component 37 to move downward synchronously. The motor shaft, which is fixed between the fixing component 36 and the stabilizing component 37, also moves downward. When the lower end of the motor shaft contacts the upper cutting edge of the drill rod 255, deep hole drilling can begin.

[0028] In some embodiments, such as Figure 2 and Figure 6 - Figure 8As shown, in a preferred embodiment of the present invention, the transmission assembly 35 includes a movable block 351, which is threaded onto the outer surface of the lead screw 34. A connecting plate 352 is fixedly connected to one side of the movable block 351. Mounting plates 353 are fixedly connected to both the upper and lower ends of the connecting plate 352. Multiple sliders 354 are fixedly connected to one side of each of the two mounting plates 353. The inner surfaces of the multiple sliders 354 are slidably connected to the outer surfaces of the two slide rails 33 respectively.

[0029] The fixing component 36 includes a connecting frame 361, which is fixedly installed on one side of the mounting plate 353 located on the upper side. A connecting block 362 is fixedly connected to one side of the connecting frame 361. A connecting rod 363 is fixedly connected to the inner cavity of the connecting block 362. A three-jaw chuck 364 is fixedly connected to the lower end of the connecting rod 363.

[0030] The stabilizing component 37 includes a perforated plate 371, which is fixedly installed on one side of the mounting plate 353 located on the lower side. The outer surface of the perforated plate 371 has three mounting grooves 372. Two slide rails 373 are fixedly connected to the inner cavity of each of the three mounting grooves 372. Electromagnets 374 are fixedly connected to the inner cavity of each of the three mounting grooves 372. Springs 375 are fixedly connected to one side of each of the three electromagnets 374. A magnetic block 376 is fixedly connected to the end of each spring 375 away from the electromagnet 374. Slider blocks 377 are fixedly connected to both sides of each magnetic block 376. The inner surfaces of the two sliders 377 are slidably connected to the outer surfaces of the two slide rails 373 respectively. A rubber block 378 is fixedly connected to the end of each magnetic block 376 away from the spring 375.

[0031] Electromagnet 374 is a Delixi MQ8-Z10 DC electromagnet. When energized, it generates magnetic force to repel magnetic block 376 and stretches spring 375 to bring rubber block 378 closer to the motor shaft, which facilitates fixing the motor shaft. When de-energized, the magnetic force disappears, spring 375 returns to its original position and pulls magnetic block 376 to move rubber block 378 away from the motor shaft.

[0032] The collecting bucket 233, drill rod 255, three-jaw chuck 364, and perforating plate 371 are concentric in the vertical direction.

[0033] In this embodiment of the invention, the metal chips and coolant generated during drilling fall into the collection hopper 233 and enter the discharge trough 22 along the collection hopper 233. At this time, the PLC controls the fan 232 to start, and the fan 232 generates air force. The mixture of metal chips and coolant will enter the collection box 241 from the feed port 242 under the action of the air force along the channel formed between the discharge trough 22 and the trough cover 231. When the mixture enters the collection box 241, it first falls on the perforated separation plate 244. The coolant flows into the lower part of the collection box 241 through the holes of the perforated separation plate 244, while the metal chips are intercepted above the perforated separation plate 244, thus achieving the separation of chips and coolant.

[0034] A liquid level sensor can be installed at the bottom of the collection box 241. When the coolant reaches a certain level, the PLC controls the solenoid valve 246 to be energized and opened, and the coolant is discharged through the drain pipe 245. It can be connected to an external coolant filtration system for treatment and recycling. When the processing is completed or the debris in the collection box 241 accumulates to a certain amount, the box cover 243 can be opened and the debris on the perforated separation plate 244 can be cleaned.

[0035] It should be noted that the three-jaw chuck 364, electromagnet 374, motor one 32, fan 232, drilling machine 254, motor two 252, etc. in this utility model are powered by a power supply and controlled by a PLC.

[0036] The PLC selected is a Siemens S7-200SMARTCPUSR40, which serves as the control core of the drilling machine. It is responsible for receiving and processing various input signals, outputting control signals, and driving the actions of each actuator. It should be noted that the specific installation methods, circuit connection methods, and control methods of the three-jaw chuck 364, electromagnet 374, motor one 32, fan 232, drilling machine 254, and motor two 252 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0037] Working principle: First, the built-in motor of the three-jaw chuck 364 is reversed using the PLC, driving the three jaws to move outward synchronously, so that the chuck is in the open state. Then, the motor shaft to be processed is placed vertically, so that the lower end of the motor shaft passes through the central through hole of the perforated plate 371 and the upper end extends between the three jaws of the three-jaw chuck 364. At this time, the built-in motor of the three-jaw chuck 364 is rotated forward by the PLC, so that the jaws move inward synchronously until they clamp the upper end of the motor shaft. At the same time, the electromagnet 374 is energized by the PLC to generate magnetic force, which repels the magnetic block 376. Under the action of magnetic force, the magnetic block 376 moves along the slide rail 373 towards the direction of the motor shaft. At this time, the spring 375 is in the stretched state, so that multiple rubber blocks 378 can be tightly attached to the outer surface of the lower end of the motor shaft, realizing double fixation of the upper and lower ends of the motor shaft and preventing vibration or displacement during processing.

[0038] After the motor shaft is clamped, the PLC controls motor 252 to start, driving the drive sprocket to rotate. The drive sprocket drives the driven sprocket to rotate via a chain, which in turn drives the spindle of the drilling machine 254 to rotate. The drill rod 255 connected to the spindle can then rotate synchronously at high speed. At the same time, the PLC controls the servo driver of motor 32 to start, causing motor 32 to drive the lead screw 34 to rotate. Since the moving block 351 is threadedly engaged with the lead screw 34, and the transmission assembly 35 is slidably connected to the slide rail 33 via slider 354, the rotational motion of the lead screw 34 is converted into... The linear movement of the moving block 351 drives the connecting plate 352, mounting plate 353, fixing component 36, and stabilizing component 37 to move downwards synchronously. The motor shaft, fixed between the fixing component 36 and the stabilizing component 37, also moves downwards. When the lower end of the motor shaft contacts the upper cutting edge of the drill rod 255, deep hole drilling can begin. During the machining process, an external cooling device can transport coolant from the center hole of the drill rod 255 to the drilling position through a pipeline to cool the drill rod 255 and the machining area and assist in chip removal.

[0039] During the drilling process, metal chips and coolant are discharged along the cutting groove of the drill rod 255 and fall into the collection hopper 233. They then enter the discharge trough 22 through the collection hopper 233. At this time, the PLC controls the fan 232 to start. The fan 232 generates air force, and the mixture of metal chips and coolant will flow along the channel formed between the discharge trough 22 and the trough cover 231 under the action of the air force, and enter the collection box 241 from the feed port 242. When the mixture enters the collection box 241, it first falls on the perforated separation plate 244. The coolant flows into the lower part of the collection box 241 through the holes of the perforated separation plate 244, while the metal chips are intercepted above the perforated separation plate 244, thus achieving the separation of chips and coolant.

[0040] A liquid level sensor can be installed at the bottom of the collection box 241. When the coolant reaches a certain level, the PLC controls the solenoid valve 246 to be energized and opened, and the coolant is discharged through the drain pipe 245. It can be connected to an external coolant filtration system for treatment and recycling. When the processing is completed or the debris in the collection box 241 accumulates to a certain amount, the box cover 243 can be opened and the debris on the perforated separation plate 244 can be cleaned.

[0041] After deep hole drilling is completed, the PLC controls motor 32 to reverse, causing motor 32 to drive lead screw 34 to rotate counterclockwise. This causes moving block 351 to drive transmission assembly 35 and motor shaft to move upward until the motor shaft returns to the initial clamping position. Then, the PLC controls electromagnet 374 to de-energize and the motor inside three-jaw chuck 364 to reverse, causing rubber block 378 and three-jaw chuck 364 to open, thus removing the fixation on the motor shaft and allowing the machined motor shaft to be removed.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
