Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing, specifically to a high-efficiency thread forming device for motor housing production. Background Technology

[0002] In the motor manufacturing process, lifting rings are typically installed on the motor housing for easy hoisting and handling. Due to the large weight of the motor or balance requirements, many models (especially medium and large industrial motors) require two lifting rings symmetrically installed, necessitating the machining of two threaded mounting holes on the motor housing. Traditional machining methods require tapping and other processes for each threaded hole individually, which is not only repetitive and time-consuming (machining time for a single threaded hole is approximately 30-60 seconds), but also prone to affecting the coaxiality of the lifting ring installation due to positioning errors. Furthermore, step-by-step machining may lead to inconsistent thread depths, affecting the load-bearing balance of the lifting ring and posing safety hazards when hoisting heavy motors. This inefficient machining method has become one of the bottlenecks restricting the efficiency improvement of motor housing production lines.

[0003] Chinese patent CN118832209A discloses a drilling device and method for motor housings. The motor housing has several process holes. The drilling device includes a processing platform with an installation port. A turntable is rotatably mounted inside the installation port. A horizontal drilling mechanism is located on one side of the installation port, and a vertical drilling mechanism is located on the other side. The horizontal drilling mechanism includes a right horizontal slide rail, a right horizontal slider, and a right drill bit. The vertical drilling mechanism includes a left horizontal slide rail, a left horizontal slider, a vertical slide rail, a vertical slider, and a vertical drill bit. The turntable is driven to move up and down by a vertical movement drive mechanism. A tray is fixedly connected to the turntable via a central column. The tray has several positioning holes, and positioning bolts are threaded into the positioning holes. This motor housing drilling device and method can quickly adapt to various models and specifications of motor housings, enabling rapid model changeover. It improves the drilling efficiency for small-batch motor housing orders by using manual drilling. However, this device still has the following problems:

[0004] When drilling threaded holes above the motor, only one point can be tapped at a time. This may result in inconsistent thread depths between the two threaded holes due to the step-by-step machining, thus affecting the balance of the lifting ring.

[0005] Based on this, this utility model designs a high-efficiency thread forming device for motor housing production to solve the above problems. Utility Model Content

Then, the hole position adjustment component 23 is used to adjust the drilling position of the drilling component 21. Then, the synchronous belt and synchronous pulley tightening component 22 is used to adjust the drive transmission of the drilling component 21. The position of the synchronous belt and synchronous pulley tightening component 22 is fixed by the drilling drive fixing component 25. Then, the drilling component 21 is started and the drilling component 21 is moved downward by the drilling up and down position adjustment component 24 to drill threaded holes synchronously at the two holes of the motor, and the depth of the threaded holes is consistent.

[0037] The drilling vertical position adjustment assembly 24 includes an operating handle 241, a rotating shaft 242, and a gear 243; the outer side wall of one set of sliding brackets 231 is rotatably connected to one end of the rotating shaft 242 via a bearing, and the outer side wall of another set of sliding brackets 231 is rotatably connected to the other end of the rotating shaft 242 via a linear bearing; a toothed groove 244 is provided on the rear side of the drilling spindle 213; the drilling spindle 213 is meshed with the gear 243 through the toothed groove 244; the gear 243 is rotatably connected to the sliding brackets 231 via a bearing; the gear 243 is connected to the rotating shaft 242 via a key, so that the rotating shaft 242 can drive the gear 243 to rotate, and the gear 243 can slide relative to the rotating shaft 242; one end of the rotating shaft 242 is fixedly connected to the operating handle 241.

[0038] The drilling drive fixing assembly 25 includes a screw 251 and a rotating arm 252; the front end of the motor bracket 221 is rotatably connected to the screw 251, and the screw 251 is threadedly connected to the front end of the bracket installed on the base 1 through a threaded sleeve; the front end of the screw 251 is fixedly connected to the rotating arm 252.

[0039] The drilling spindle 213 includes a drive shaft 2131, a drilling shaft 2132, a vertical moving housing 2133, and a drilling screw 2134.

The upper end of the drive shaft 2131 and the drilling shaft 2132 are connected by a key, so that the drive shaft 2131 can slide relative to the drilling shaft 2132 while driving the drilling shaft 2132. The lower end of the drilling shaft 2132 is fixedly connected to the drilling screw 2134. The toothed groove 244 is opened on the outside of the vertical moving housing 2133, and the drilling shaft 2132 is rotatably connected to the vertical moving housing 2133.

[0040] In this invention, the operator adjusts the drilling position of the drilling spindle 213 on the motor by sliding the motor bracket 221 along the slide rail 233 and limiting its position via the slider 232. At this time, the gear 243 and the sliding bracket 231 slide relative to the rotating shaft 242. After both drilling positions are adjusted, the operator tightens the locking screw 234 to lock the slider 232 against the slide rail 233. By rotating the arm 252, the operator tightens the screw 251, causing the motor bracket 221 to slide along the slide rail 222 via the slider 223, thus tightening the synchronous belt of the synchronous belt and synchronous belt pulley transmission assembly 212. Then, the operator starts the motor 211, which drives the synchronous belt and synchronous belt pulley transmission assembly 212. The transmission of the 2nd generation drives the two drilling spindles 213 to work. Then, rotating the operating handle 241 drives the two gears 243 to rotate through the rotating shaft 242. The rotation of the two gears 243 drives the vertical moving housings 2133 of the two drilling spindles 213 to slide downward synchronously to the limit through the two tooth grooves 244. At this time, the driving shaft 2131 of the drilling spindle 213 drives the drilling screw 2134 to rotate through the drilling shaft 2132. At this time, the drilling screws 2134 of the two drilling spindles 213 synchronously drill threaded holes at the two threaded hole positions of the motor. After drilling is completed, rotating the operating handle 241 in the opposite direction drives the drilling spindle 213 to reset. This achieves synchronous drilling of threaded holes in the two lifting eye holes of the motor, and the threaded hole depth is consistent.

Then, the motor is placed into the motor positioning groove 312 for positioning. The motor positioning groove 312 limits the motor during the motor drilling process to prevent the motor from shifting due to mechanical vibration, thereby achieving rapid positioning of the motor. The corresponding motor positioning plate 311 can be quickly replaced according to the motor model.
