[0002] Currently, the motor housing is an important component of the motor. In order to enable the motor to be installed on other equipment during subsequent use, the motor housing needs to be drilled and tapped during processing to form threaded assembly holes, which facilitates the use and assembly of the motor.

Before tapping, the orientation of the mounting holes in each housing needs to be aligned for uniform tapping by the tapping machine. Therefore, how to automatically align the orientation of the mounting holes in each motor housing on an automated production line is a pressing issue that needs to be addressed.

[0027] 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.

[0028] like Figure 1 , 2 As shown, this embodiment provides an automatic positioning and tapping device for motor housing, which includes a slide groove 1, a positioning mechanism 2, a tapping mechanism 3, and a conveying mechanism 5.

[0029] The positioning mechanism 2 rotates the four motor housings 4 on the slide 1, aligning the mounting holes 41 on the motor housings 4 with the tapping positions. Next, the transport mechanism 5 transports the rotated motor housings to the tapping mechanism 3. The tapping mechanism 3 taps the mounting holes 41 on the rotated motor housings 4. After tapping, the transport mechanism 5 sends the four motor housings 4 to the next workstation.

[0030] like Figure 2 , 3 As shown in Figures 4 and 5, the positioning mechanism 2 in this embodiment includes a guide assembly, a rotation assembly, a positioning detection assembly, and a first clamping assembly 23.

[0031] The rotating assembly includes a rotary motor 221, a driving gear 222, a driven gear 223, a rotating shaft 224, and a positioning turntable 225. The rotary motor 221 is fixed to the bottom of the slide 1. The driving gear 222 is fixed to the motor shaft of the rotary motor 221. The rotating shaft 224 is rotatably connected to the slide 1 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 4. The motor housing 4 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 then drives the positioning turntable 225 to rotate, thus rotating the motor housing 4.

[0032] 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 4, 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 4. Figure 8 , 9 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 4 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.

[0033] 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 41 on the motor housing 4 has rotated to the position suitable for tapping. When the mounting hole 41 on the motor housing 4 rotates to below the photoelectric switch sensor, the photoelectric switch sensor detects the mounting hole 41, indicating that the mounting hole 41 has rotated into position, and the positioning turntable 225 stops rotating.

[0034] Finally, the first clamping component 23 clamps the motor housing 4 that has been rotated into place. The transport mechanism 5 drives the first clamping component 23 to transport the motor housing 4 to the tapping mechanism 3. Then the first clamping component 23 is released, and the transport mechanism 5 drives the first clamping component 23 back to its original position.

[0035] like Figure 5As shown, the tapping mechanism 3 in this embodiment includes an automatic tapping machine 31 and a second 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 9 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 second clamping assembly 32 clamps the motor housing 4, the automatic tapping machine 31 can tap two threaded mounting holes 41 on each motor housing 4. After tapping, the transport mechanism 5, driven by the second clamping assembly 32, transports the motor housing 4 to the next workstation.

[0036] like Figure 6 As 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 first vertical support plate 51 and the second vertical support plate 52 are respectively fixed at the bottom of both ends of the slide groove 1. The two ends of the sliding guide post 55 are respectively connected to the first vertical support plate 51 and the second vertical support plate 52. The first linear bearing seat 57, the second linear bearing seat 58 and the third linear bearing seat 59 are all slidably connected to the sliding guide post 55. 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 first clamping assembly 23 and the second 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 23 and a second clamping assembly 32, which can drive the first clamping assembly 23 and the second clamping assembly 32 to move back and forth.

[0037] like Figure 7As shown, the first clamping assembly 23 and the second clamping assembly 32 in this embodiment adopt the same structure. The clamping assembly includes two clamping cylinders 101, which are respectively mounted on two transport mounting plates 56 and located on both sides of the motor housing 4. Each clamping cylinder 101 is equipped with a clamping plate 102, and the clamping plate 102 has a groove that matches the outer wall of the motor housing 4. When the two clamping cylinders 101 extend simultaneously, they can drive the two clamping plates 102 to clamp the motor housing 4; conversely, when they extend, the motor housing 4 is released.
