Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of metal processing, and in particular to a drilling machine and method for motor processing. BACKGROUND

[0002] The existing motor shell processing equipment generally adopts a single drill bit or a single-sided multi-drill bit to process each face one by one when forming a heat dissipation fin structure by grooving multiple faces of the motor shell. After processing a groove on each side, the equipment needs to be stopped to adjust the angle of the workpiece or move the drill bit position, and frequent back-and-forth movement and turning operations are required. This not only increases the idle stroke time, but also significantly reduces the overall cutting efficiency. Moreover, the multiple clamping and positioning operations easily cause cumulative processing errors, affecting the position accuracy and consistency of the heat dissipation grooves, and it is difficult to meet the needs of mass production. In addition, the existing equipment lacks a structure design for synchronous operation of multiple faces during processing, and cannot simultaneously mill grooves on the four sides of the motor shell, which restricts the development of rapid forming process of the motor shell heat dissipation structure.

[0003] In addition, when strip-shaped through holes are formed on the surface of the motor shell for internal and external ventilation and heat dissipation, the conventional drilling equipment also relies on a single drill bit or a single-sided multiple drill bits to punch holes on each face one by one. After processing each face, the workpiece needs to be repositioned or the drill bit direction needs to be adjusted, resulting in a complicated drilling process, a long cycle, and low production efficiency. Moreover, due to the multiple switching of processing faces, the hole alignment accuracy is difficult to guarantee, and the hole may be offset or blocked, which affects the effective export of heat from the motor and cannot fully utilize the ventilation and cooling effect of the heat dissipation holes. Therefore, there is an urgent need for a special processing equipment that can simultaneously groove and drill multiple sides of the motor shell synchronously to realize high-efficiency and high-precision integrated forming of multiple heat dissipation fins and strip-shaped through holes, and to improve the heat dissipation performance and manufacturing efficiency of the motor shell.

[0009] Preferably, the driving mechanism includes a threaded shaft threadedly connected to the middle of the middle plate.

A gear sleeve is slidably sleeved on the side of the middle plate away from the connecting sleeve, and the gear sleeve is slidably sleeved with the threaded shaft. Gear sets are provided on the upper front side and lower rear side of the middle plate near the gear sleeve, and the gear sets mesh with the gear sleeve. Connecting rods are movably sleeved on the upper front side and lower rear side of the middle plate, and the connecting rods are movably sleeved with the connecting sleeve.

[0013] Preferably, the gear set can be replaced by a transmission in actual use, and the thickness of the sliding rod is greater than that of the rear side of the sleeve plate.

[0014] A drilling method for a drilling machine used in motor machining includes the following steps: S1: First, install the motor housing onto the feeding mechanism. The feeding mechanism then pushes the motor housing to the middle of the multiple drill sleeve mechanisms. S2: By activating the feed mechanism, the drill bit of the drill sleeve mechanism is brought close to the motor housing; S3: Next, by starting the drive mechanism, the drive mechanism drives the motor housing to move left and right. At the same time, the drive mechanism drives the drill sleeve mechanism through the connecting mechanism to cut and slot the surface of the motor housing. S4: Finally, the slotted motor housing is opened by simultaneously activating the feeding mechanism and the forward and reverse start-up drive mechanism.

[0015] The beneficial effects of this invention are as follows: 1. When the drive mechanism is started in the forward direction, the drive mechanism and the feeding mechanism synchronously push the motor housing to move to the right. At the same time, the drive mechanism drives the connecting mechanism to operate, and the connecting mechanism drives the two adjacent drill bits of the drill sleeve mechanism to rotate in opposite directions. At this time, when the drive mechanism pushes the motor housing to move to the right and contact the drill bit, the drill bit cuts the motor housing. Similarly, when the left end of the motor housing moves to the right side of the drill bit, the feeding mechanism is started again, so that the drill bit moves towards the motor housing again by a certain cutting depth. Then, the drive mechanism and the feeding mechanism are started in reverse, so that the motor housing moves to the left, and the drill bit cuts the motor housing again. In this way, by setting multiple sets of drill sleeve mechanisms and connecting mechanisms in a square shape along the shape of the motor housing, it is possible to quickly groove the four sides of the motor housing, so that multiple sets of heat sinks are formed on the four sides of the motor housing. This overcomes the problem of low cutting efficiency caused by the need for frequent back-and-forth and turning when using a single or single-sided multiple drill bit to groove the four sides of the motor housing to make multiple sets of heat sinks.

[0016] 2. In this invention, after multiple sets of heat sinks are formed on the four sides of the motor housing, the feeding mechanism is activated. The telescopic end of the feeding mechanism retracts, causing the feed mechanism to drive the drill bit to contact the surface of the motor housing via the movable shaft. Then, the drive mechanism and hydraulic sleeve are activated alternately in both directions. At this time, the drive mechanism and hydraulic sleeve drive the motor housing to move to the left a certain distance, and then to the right a certain distance, causing the motor housing to move alternately left and right. The drive mechanism drives the drill bits of multiple drill sleeve mechanisms to rotate through the connecting mechanism. During the alternating left and right movement of the motor housing, the feeding mechanism is continuously activated, causing the telescopic end of the feeding mechanism to continuously and slowly retract. At this time, the rotating drill bit slowly moves towards the center of the motor housing. Finally, multiple drill bits open multiple strip-shaped holes on the surface of the motor housing, penetrating the surface of the motor housing and its inner cavity for heat dissipation. This overcomes the problem of low drilling efficiency caused by the need for frequent back-and-forth and turning when opening multiple heat dissipation holes on the four sides of the motor housing with a single or multiple drill bits on one side.

[0025] Please refer to Figures 1 to 8 As shown, a drilling machine for motor processing includes a housing 1, a side plate 101 fixedly mounted on the left end of the housing 1, and a feeding mechanism 2 provided on the right side of the housing 1. It also includes: Connecting sleeve 3 is fixedly fitted onto the right side of the inner cavity of outer shell 1; Two first mounting plates 4 are symmetrically arranged on the left side of the connecting sleeve 3 inside the outer shell 1; Multiple drill sleeve mechanisms 5 are circumferentially and equidistantly arranged in the middle of the two first mounting plates 4; Multiple connecting mechanisms 6 are disposed on the outer sides of the two first mounting plates 4; The middle plate 102 is fixedly sleeved in the middle of the inner cavity of the outer shell 1; Multiple support columns 103 are fixedly installed on the front, back and top and bottom sides of the right side of the middle plate 102, and the support columns 103 are fixedly connected to two connecting mechanisms 6 on the same side. Drive mechanism 7 is disposed between the middle plate 102 and the two connecting mechanisms 6; The feeding mechanism 8 is disposed between the side plate 101, the middle plate 102 and the multiple connecting mechanisms 6; The feeding mechanism 2 includes a base plate 201, which is fixedly installed at the bottom of the right side of the outer shell 1. A support plate 202 is fixedly installed on the right side of the upper surface of the base plate 201. A hydraulic sleeve 203 is fixedly installed in the middle of the left side of the support plate 202. A limit sleeve 204 is fixedly sleeved on the side of the extension end of the hydraulic sleeve 203 away from the support plate 202. The left side of the output end of the hydraulic sleeve 203 is fitted into the inner hole of the motor housing, thereby limiting the rotation of the motor housing axis and preventing the drill bit 503 from rotating when cutting the outer surface of the motor housing, which would reduce the cutting accuracy.

[0026] Please see Figure 3 , Figure 6 and Figure 7 As shown, the drill sleeve mechanism 5 includes a sliding block 501, which is slidably sleeved in the middle of the two first mounting plates 4. A movable shaft 502 is slidably sleeved in the middle of the sliding block 501. A drill bit 503 is slidably sleeved at the bottom of the movable shaft 502. A collar 504 is fixedly sleeved on the upper part of the curved surface of the movable shaft 502. The sliding block 501 has a mounting groove in the middle of its inner cavity, which is filled with lubricating oil. This reduces the contact area between the movable shaft 502 and the sliding block 501, thereby reducing the frictional resistance between them and preventing the high-speed rotating movable shaft 502 from undergoing severe friction and high-temperature deformation. The movable shaft 502 and the drill bit 503 are fitted with a transition fit, which allows for the quick installation and unloading of the drill bit 503 at the bottom of multiple movable shafts 502 according to the size and shape of the motor housing.

[0027] Please see Figures 2 to 6As shown, the connecting mechanism 6 includes two second mounting plates 601, which are respectively fixedly mounted on the outer sides of two first mounting plates 4. A first inner plate 602 is fixedly mounted on the bottom of the two second mounting plates 601, and a second inner plate 603 is fixedly mounted on the middle of the two second mounting plates 601. A third inner plate 604 is fixedly mounted on both ends of the second inner plate 603. A plurality of sleeve rods 605 are equidistantly sleeved on the middle of the first inner plate 602. A reversing wheel 606 is fixedly sleeved on the curved surface of the sleeve rod 605. Two adjacent reversing wheels 606 mesh with each other. A first conical wheel 607 is fixedly mounted on the top of the sleeve rod 605. A gear shaft 608 is fixedly mounted on the middle of the two third inner plates 604. A plurality of second conical wheels 609 are equidistantly sleeved on the curved surface of the gear shaft 608. The second conical wheels 609 mesh with their adjacent first conical wheels 607. A third conical wheel 610 is fixedly mounted on both ends of the gear shaft 608. The sleeve 605 is slidably sleeved in the middle of the inner cavity of the sliding block 501. The contact surface between the sleeve 605 and the sliding block 501 is a smooth surface, thereby reducing the frictional resistance when the rotating movable shaft 502 slides up and down along the sleeve 605, reducing the frictional loss between the movable shaft 502 and the sleeve 605, and improving the service life of the movable shaft 502 and the sleeve 605.

[0028] Please see Figures 1 to 3 As shown, the drive mechanism 7 includes a threaded shaft 701, which is threadedly connected to the middle of the middle plate 102. A rotating seat 702 is movably sleeved at one end of the threaded shaft 701 near the connecting sleeve 3. A gear sleeve 703 is slidably sleeved on the side of the middle plate 102 away from the connecting sleeve 3, and the gear sleeve 703 is slidably sleeved with the threaded shaft 701. Gear sets 704 are provided on both the upper front side and the lower rear side of the middle plate 102 near the gear sleeve 703, and the gear sets 704 mesh with the gear sleeve 703. Connecting rods 705 are movably sleeved on both the upper front side and the lower rear side of the middle plate 102, and the connecting rods 705 are connected to the connecting... The connecting sleeve 3 is movably connected. A driven wheel 706 is fixedly installed at the end of the connecting rod 705 near the gear sleeve 703. The gear set 704 meshes with the driven wheel 706. A fourth cone wheel 707 is fixedly installed at the end of the connecting rod 705 away from the gear sleeve 703. The fourth cone wheel 707 meshes with two third cone wheels 610 on the same side. A driving component 708 is fixedly installed on the left side of the middle plate 102. A driving wheel 709 is fixedly installed at the output end of the driving component 708. A connecting wheel 710 is fixedly installed on the left side of the middle plate 102. The connecting wheel 710 meshes with the gear sleeve 703. In actual use, the gear set 704 can be replaced by a gearbox to increase the ratio of the rotation speed of the drill bit 503 at the bottom of the drill bushing mechanism 5 driven by the drive mechanism 7 through the connecting mechanism 6 to the moving speed of the motor housing driven by the drive mechanism 7. This allows the drill bit 503 to rotate faster through the gearbox when the moving speed of the motor housing remains constant, thereby improving the cutting speed and accuracy.

[0029] Please see Figure 2 and Figure 8 As shown, the feeding mechanism 8 includes a hydraulic rod 801, which is fixedly installed in the middle of the right side of the side plate 101. A connecting plate 802 is fixedly installed at the telescopic end of the hydraulic rod 801. Multiple curved rods 803 are fixedly installed at equal intervals around the side of the connecting plate 802 away from the hydraulic rod 801. A sliding rod 804 is movably sleeved at the end of the curved rod 803 near the middle plate 102. The sliding rod 804 is slidably sleeved with the middle plate 102. A sleeve plate 805 is fixedly installed at the end of the sliding rod 804 away from the hydraulic rod 801. The movable shaft 502 is slidably sleeved with the sleeve plate 805. The bottom surface of the sleeve plate 805 slides against the top end of the collar 504. The thickness of the sliding rod 804 is greater than that of the rear side of the sleeve plate 805. This prevents the sliding rod 804 from bending when it pushes the movable shaft 502 through the sleeve plate 805 to drive the drill bit 503 to contact the motor housing, thus avoiding a reduction in cutting accuracy. The sleeve plate 805 is made of high-strength, high-temperature resistant material, specifically tungsten alloy. This also prevents the sliding rod 804 from bending when it pushes the movable shaft 502 to drive the drill bit 503 to contact the motor housing, thus avoiding a reduction in cutting accuracy. At the same time, the high-temperature resistant tungsten alloy material can prevent the rotating movable shaft 502 from rubbing against the sleeve plate 805, thus preventing the movable shaft 502 and the sleeve plate 805 from deforming and jamming due to high temperature.

[0030] Please see Figures 1 to 8 As shown, a method for machining an electric motor includes the following steps: S1: First, install the motor housing onto the feeding mechanism 2. The feeding mechanism 2 then pushes the motor housing to the middle of the multiple drill sleeve mechanisms 5. S2: By activating the feed mechanism 8, the drill bit 503 of the drill sleeve mechanism 5 is brought close to the motor housing; S3: Next, by starting the drive mechanism 7, the drive mechanism 7 drives the motor housing to move left and right. At the same time, the drive mechanism 7 drives the drill sleeve mechanism 5 to cut and slot the surface of the motor housing through the connecting mechanism 6. S4: Finally, the motor housing is opened by simultaneously starting the feed mechanism 8 and the forward and reverse start drive mechanism 7.

[0031] Working principle: When using this invention, first, the motor housing is fitted onto the left side of the telescopic end of the hydraulic sleeve 203 and the limiting sleeve 204 is brought into contact with the hydraulic sleeve 203. Then, the hydraulic sleeve 203 is started, and the telescopic end of the hydraulic sleeve 203 pushes the motor housing to move towards the drill sleeve mechanism 5, so that the left end of the motor housing is in contact with the drill bit 503. Then, the hydraulic rod 801 is started, and the telescopic end of the hydraulic rod 801 moves to the left. The telescopic end of the hydraulic rod 801 drives the connecting plate 802 to move to the left. The connecting plate 802 pulls multiple sliding rods 804 closer to each other through the crank rod 803. The sliding rods 804 drive the movable shaft 502 to move towards the motor housing through the sleeve plate 805. The movable shaft 502 drives the drill bit 503 to move towards the motor housing until the distance between the end of the drill bit 503 away from the movable shaft 502 and the outer side of the motor housing is equal to the single cutting depth of the motor housing. Then, the drive unit 708 is started in the forward direction. The output end of the drive unit 708 drives the driving wheel 709 to rotate. The driving wheel 709 drives the connecting wheel 710 to rotate. The connecting wheel 710 drives the gear sleeve 703 to rotate. The gear sleeve 703 drives the threaded shaft 701 to rotate. The threaded shaft 701 moves to the right. The threaded shaft 701 pushes the motor housing to the right through the rotating seat 702. At the same time, the telescopic end of the hydraulic sleeve 203 retracts synchronously to the right with the threaded shaft 701. When the gear sleeve 703 rotates, the gear sleeve 703 drives the gear set 704 to rotate. The gear set 704 drives the driven wheel 706 to rotate. 6 drives the connecting rod 705 to rotate, the connecting rod 705 drives the fourth cone wheel 707 to rotate, the fourth cone wheel 707 drives the third cone wheel 610 to rotate, the second mounting plate 601 drives the gear shaft 608 to rotate, the gear shaft 608 drives the second cone wheel 609 to rotate, the second cone wheel 609 drives the first cone wheel 607 to rotate, the first cone wheel 607 drives the sleeve rod 605 fixedly connected to it to rotate, the rotating sleeve rod 605 drives another adjacent reversing wheel 606 to rotate in the opposite direction through the reversing wheel 606, at this time the reversing wheel 606 rotating in the opposite direction drives the reversing wheel 606 fixedly connected to it to rotate in opposite directions; This results in two adjacent sleeve rods 605 rotating in opposite directions. Since the sleeve rods 605 drive the movable shaft 502 to rotate, and the movable shaft 502 drives the drill bit 503 to rotate, the two adjacent sleeve rods 605, rotating in opposite directions, drive the two adjacent drill bits 503 to rotate in opposite directions via the movable shaft 502. At this time, the threaded shaft 701 pushes the motor housing to the right through the rotating seat 702, contacting the drill bit 503. The drill bit 503 cuts the motor housing. Similarly, when the left end of the motor housing moves to the right side of the drill bit 503, the feed mechanism 8 is restarted, causing the drill bit 503 to move again. The motor housing moves a certain cutting depth in the direction of the movement. Then, the drive unit 708 and the hydraulic sleeve 203 are reversed to move the motor housing to the left. The drill bit 503 cuts the motor housing again. This achieves the goal of quickly slotting the four sides of the motor housing by setting multiple sets of drill sleeve mechanisms 5 and connecting mechanisms 6 in a square shape along the shape of the motor housing. This forms multiple sets of heat sinks on the four sides of the motor housing, overcoming the problem of low cutting efficiency caused by the need for frequent back-and-forth movement and turning when slotting the four sides of the motor housing to form multiple sets of heat sinks with a single or multiple drill bits on one side. In this invention, after multiple sets of heat sinks are formed on the four sides of the motor housing, the feeding mechanism 8 is activated. The telescopic end of the feeding mechanism 8 retracts, causing the feeding mechanism 8 to drive the drill bit 503 to contact the surface of the motor housing via the movable shaft 502. Then, the drive mechanism 7 and the hydraulic sleeve 203 are activated alternately in both directions. At this time, the drive mechanism 7 and the hydraulic sleeve 203 drive the motor housing to move to the left a certain distance, and then to the right a certain distance, causing the motor housing to move alternately left and right. The drive mechanism 7 drives the drill bit 503 of the multiple drill sleeve mechanisms 5 to rotate through the connecting mechanism 6. During the alternating left and right movement of the motor housing, the feeding mechanism 8 is continuously activated, causing the telescopic end of the feeding mechanism 8 to continuously and slowly retract. At this time, the rotating drill bit 503 slowly moves towards the center of the motor housing. Finally, the multiple drill bits 503 open multiple strip holes on the surface of the motor housing that penetrate the surface of the motor housing and its inner cavity for heat dissipation. This overcomes the problem of low drilling efficiency caused by the need for frequent back-and-forth and turning when opening multiple heat dissipation holes on the four sides of the motor housing with a single or multiple drill bits on one side.
