[0038] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0039] like Figure 1 , 4 As shown, this embodiment provides an automatic tapping device for motor housings, which includes a feeding and conveying mechanism 1, a chute 8, a straightening mechanism 9, a positioning mechanism 2, a tapping mechanism 3, a thread detection mechanism 4, a conveying mechanism 5, and a receiving tray 7.

[0040] The feeding and conveying mechanism 1 transports the motor housings 6 with the assembly holes 61 drilled in batches to one end of the slide 8. The slide 8 passes sequentially through the leveling mechanism 9, the positioning mechanism 2, the tapping mechanism 3, and the thread detection mechanism 4. Then, the leveling mechanism 9 clamps and levels the motor housings 6 that have entered the slide 8. In this embodiment, four motor housings 6 can be leveled at a time. Then, the transport mechanism 5 sends the four leveled motor housings 6 together to the positioning mechanism 2. The positioning mechanism 2 rotates the leveled motor housings 6, rotating the assembly holes 61 on the motor housings 6 to a position suitable for tapping. Next, the tapping mechanism 3 taps the assembly holes 61 on the rotated motor housings 6. After tapping, the transport mechanism 5 sends the four motor housings 6 to the thread detection mechanism 4. The thread detection mechanism 4 performs thread detection on each tapped assembly hole 61. If the thread of an assembly hole 61 on a motor housing 6 is found to be unqualified, the motor housing 6 is manually removed. Finally, the conveying mechanism 5 transports the next batch of tapped motor housings 6 to the thread inspection mechanism 4. The receiving tray 7 is located at the other end of the slide 8. While transporting, all the inspected motor housings 6 are pushed onto the receiving tray 7.

[0041] like Figure 2 As shown, the feeding and conveying mechanism 1 of this embodiment includes a receiving trough 11, a frame 12, a belt conveyor assembly 13, baffle fixing blocks 14, and baffles. The receiving trough 11 is fixed to one end of the frame 12, and the other end of the frame 12 is connected to one end of the chute 8. The belt conveyor assembly 13 is mounted on the frame 12 and is used to convey the motor housing 6 with the assembly holes 61 drilled. The baffle fixing blocks 14 are mounted on the frame 12 and located on both sides of the belt conveyor assembly 13, and the baffles are fixed on the baffle fixing blocks 14. The motor housing 6 with the assembly holes 61 drilled enters from the receiving trough 11 and then enters the chute 8 under the conveying of the belt conveyor assembly 13. The belt conveyor assembly 13 adopts a conventional structure of motor, belt, and pulley. There are baffle fixing blocks 14 on both sides of the belt, and baffles can be installed on the baffle fixing blocks 14 to prevent the motor housing 6 from falling off. The baffles are not shown in the figure.

[0042] like Figure 3As shown, the alignment mechanism 9 in this embodiment includes an anti-tipping vertical plate 15, an anti-tipping pressure plate 16, and a first clamping assembly 17. The anti-tipping vertical plate 15 is fixed to one end of the slide groove 8, and the anti-tipping pressure plate 16 is fixed on the anti-tipping vertical plate 15, located at the top of the motor housing 6. The first clamping assembly 17 is used to clamp the motor housing 6 entering the slide groove 8, and is connected to the transport mechanism 5. The motor housing 6 enters the slide groove 8 between the two anti-tipping vertical plates 15. The anti-tipping pressure plate 16 is located at the top of the motor housing 6 to prevent it from tipping over. Then, the first clamping assembly 17 clamps the motor housing 6 on the slide groove 8. The transport mechanism 5 moves the first clamping assembly 17 to transport the motor housing 6 to the positioning mechanism 2. Then, the first clamping assembly 17 is released, and the transport mechanism 5 brings the first clamping assembly 17 back to its original position.

The rotating shaft 224 is rotatably connected to the slide 8 via bearings. The driven gear 223 is fixed to the rotating shaft 224 and meshes with the driving gear 222. The positioning turntable 225 is fixed to the top of the rotating shaft 224 and is used to place the motor housing 6. The motor housing 6 is moved onto the positioning turntable 225, and then the rotary motor 221 starts, driving the rotating shaft 224 to rotate via the driving gear 222 and the driven gear 223. This rotation, in turn, drives the positioning turntable 225 to rotate, thus rotating the motor housing 6.

[0045] The guide assembly includes a first support plate 211, a first height adjustment plate 212, a first track mounting plate 213, a pressing cylinder 214, a first slider mounting plate 215, a bearing housing 216, a guide shaft 217, a positioning cylinder 218, and a positioning plate 219. The first height adjustment plate 212 is fixed to the first support plate 211. The first track mounting plate 213 is movably connected to the first height adjustment plate 212 via screws, allowing adjustment of the mounting height of the first track mounting plate 213. The pressing cylinder 214 is fixed to the top of the first track mounting plate 213. The first slider mounting plate 215 is connected to the piston rod of the pressing cylinder 214. The bearing housing 216 is fixed to the first slider mounting plate 215. The first slider mounting plate 215 is slidably connected to the guide rail on the first track mounting plate 213 via a slider. The guide shaft 217 is rotatably connected to the bearing housing 216. The positioning cylinder 218 is fixed to the bearing housing 216. The positioning plate 219 is connected to the piston rod of the positioning cylinder 218. Before rotating the motor housing 6, the pressing cylinder 214 drives the bearing housing 216 and guide shaft 217 to press down until the four guide shafts 217 are pressed into the shaft holes of the motor housing 6. Figure 11 , 12 As shown, bearings 2171 are fixed at both the upper and lower ends of the guide shaft 217. The bearings 2171 are installed in the bearing housing 216, allowing the guide shaft 217 to rotate within the bearing housing 216. Then, the positioning turntable 225 drives the motor housing 6 to rotate. The positioning cylinder 218 extends the positioning plate 219 downwards, and during the rotation of the guide shaft 217, the arc-shaped groove on the positioning plate 219 provides auxiliary positioning for the guide shaft 217.

[0046] The positioning detection assembly includes a detection adjustment plate 241, a detection mounting plate 242, a sensor mounting plate 243, and a photoelectric switch sensor (not shown in the figure). The detection adjustment plate 241 is movably connected to the first track mounting plate 213 via screws, allowing adjustment of the installation height of the detection adjustment plate 241. The detection mounting plate 242 is connected to the detection adjustment plate 241. The sensor mounting plate 243 is fixed to the detection mounting plate 242, and the photoelectric switch sensor is fixed to the sensor mounting plate 243. The photoelectric switch sensor is used to detect whether the mounting hole 61 on the motor housing 6 has rotated to a position suitable for tapping. When the mounting hole 61 on the motor housing 6 rotates to below the photoelectric switch sensor, the photoelectric switch sensor detects the mounting hole 61, indicating that the mounting hole 61 has rotated into position, and the positioning turntable 225 stops rotating.

[0047] Finally, the second clamping assembly 23 clamps the motor housing 6 that has been rotated into place. The transport mechanism 5 drives the second clamping assembly 23 to transport the motor housing 6 to the tapping mechanism 3. Then the second clamping assembly 23 is released, and the transport mechanism 5 drives the second clamping assembly 23 back to its original position.

[0048] like Figure 7As shown, the tapping mechanism 3 in this embodiment includes an automatic tapping machine 31 and a third clamping assembly 32. The automatic tapping machine 31 in this embodiment uses an automatic tapping machine from Ax Automation Equipment Co., Ltd., such as... Figure 11 As shown, the internal mechanism employs a central driving gear 311 to drive the side driven gears 312 on both sides to rotate. The side driven gears 312 then drive the coaxial gear 313 to rotate, which in turn drives the tapping head gear 314 to rotate. This allows for the simultaneous driving of four pairs of tapping heads 315 for tapping. After the third clamping assembly 32 clamps the motor housing 6, the automatic tapping machine 31 can tap two threaded assembly holes 61 on each motor housing 6. After tapping, the transport mechanism 5 drives the third clamping assembly 32 to transport the motor housing 6 to the thread inspection mechanism 4. During the transport process, the third clamping assembly 32 can push the previously inspected motor housings 6 at the thread inspection mechanism 4 into the receiving tray 7. After the thread inspection mechanism 4 completes the inspection, the third clamping assembly 32 releases the inspected motor housings 6, and the transport mechanism 5 then returns the third clamping assembly 32 to its original position.

[0049] like Figure 8 As shown, the thread detection mechanism 4 in this embodiment includes an anti-tipping side plate 41, a second support plate 42, a second height adjustment plate 43, a second track mounting plate 44, a detection cylinder 45, a second slider mounting plate 46, a mounting block 47, and a thread detection probe 48. The second height adjustment plate 43 is fixed on the second support plate 42, and the second track mounting plate 44 is movably connected to the second height adjustment plate 43 by screws, allowing adjustment of the installation height of the second track mounting plate 44. The detection cylinder 45 is fixed on the top of the second track mounting plate 44, and the second slider mounting plate 46 is connected to the piston rod of the detection cylinder 45. The second slider mounting plate 46 is slidably connected to the guide rail on the second track mounting plate 44 via a slider. The mounting block 47 is fixed on the second slider mounting plate 46, and the thread detection probe 48 is mounted on the mounting block 47. The anti-tipping side plate 41 is fixed at the other end of the slide groove 8 and is located on the side of the motor housing 6 to prevent the motor housing 6 from tipping over during movement. When performing thread inspection on the assembly hole 61, the inspection cylinder 45 drives the thread inspection probe 48 to press down, so that the thread inspection probe 48 is pressed into the assembly hole 61, and the thread can be inspected.

[0050] like Figure 9As shown, the conveying mechanism 5 in this embodiment includes a first vertical support plate 51, a second vertical support plate 52, a conveying cylinder 53, a bearing seat main connecting plate 54, a sliding guide post 55, a conveying mounting plate 56, a first linear bearing seat 57, a second linear bearing seat 58, a third linear bearing seat 59, and a bearing seat slave connecting plate 501.

The piston rod of the transport cylinder 53 passes through the first vertical support plate 51 and is connected to the middle of the bearing seat main connecting plate 54. The two ends of the bearing seat main connecting plate 54 are respectively connected to a set of first linear bearing seats 57. The first linear bearing seat 57, the second linear bearing seat 58 and the third linear bearing seat 59 are connected to each other through the bearing seats from the connecting plate 501. The transport mounting plate 56 is connected to the top of the first linear bearing seat 57, the second linear bearing seat 58 and the third linear bearing seat 59. The transport mounting plate 56 is used to install the first clamping assembly 17, the second clamping assembly 23 and the third clamping assembly 32. The extension and retraction of the piston rod of the transfer cylinder 53 can drive the first linear bearing housing 57, the second linear bearing housing 58, and the third linear bearing housing 59 to move on the sliding guide post 55. The top of the first linear bearing housing 57, the second linear bearing housing 58, and the third linear bearing housing 59 is equipped with a transfer mounting plate 56. The transfer mounting plate 56 is equipped with a first clamping assembly 17, a second clamping assembly 23, and a third clamping assembly 32, which can drive the first clamping assembly 17, the second clamping assembly 23, and the third clamping assembly 32 to move back and forth.

[0051] like Figure 10 As shown, the first clamping assembly 17, the second clamping assembly 23, and the third clamping assembly 32 in this embodiment adopt the same structure.
