Description

Technical Field

[0001] This utility model relates to the field of stator processing technology, specifically a drilling and positioning device for processing electric motor stators. Background Technology

[0002] The stator is the stationary part of the electric motor. It consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating (outputting) current. The stator core is composed of multiple layers of stacked core units, with transverse through slots formed between adjacent core units. Radial serrations are provided on the inner circumference of each core unit, and longitudinal slots are formed between adjacent serrations.

[0003] After the stator core is stacked, holes need to be drilled at both the top and bottom ends of the stator core. The hole positions require high precision, and it is difficult to accurately position the holes during the drilling process. Therefore, this application proposes a drilling and positioning device for stator processing to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0025] Combination Figure 1-5 As shown, this embodiment provides a drilling and positioning device for machining electric motor stators, including: a main body mechanism 100 and a positioning mechanism 200.

[0026] The main structure 100 includes a conical seat 110, a sleeve 120 fixed in the middle of the conical seat 110 and extending into the conical seat 110, a plurality of bearings 130 with outer rings fixed on the inner wall of the sleeve 120, a rotating shaft 140 with one end fixed to the inner ring of the bearing 130 and the other end extending out of the sleeve 120, an angle sensor 150 installed on the inner wall of the sleeve 120 and fixedly connected to the bottom end of the rotating shaft 140, and an angle display screen 160 fixed on the top end of the rotating shaft 140.

[0027] The tapered seat 110 is used to place the stator and ensures that when the stator is placed on the tapered seat 110, the central axis of the stator and the central axis of the sleeve 120 are kept on the same vertical line. The sleeve 120 is fixed inside the tapered seat 110 and is used to fix the bearing 130. At least two bearings 130 are provided to install the rotating shaft 140 and ensure the stability of the rotating shaft 140 when rotating. The rotating shaft 140 is used to install the positioning mechanism 200 and facilitates the rotation of the positioning mechanism 200.

[0028] Angle sensor 150 is used to monitor the rotation angle of shaft 140 in real time, that is, to monitor the rotation angle of positioning mechanism 200. Angle display screen 160 is used to display the monitoring data of angle sensor 150 in real time.

[0029] The positioning mechanism 200 is used to position the drilling position and includes a collar 210 slidably sleeved on the rotating shaft 140, a rangefinder 220 fixed on one side of the collar 210, a frame 230 fixed on the other side of the collar 210, a positioning seat 240 slidably disposed on the frame 230, an adjusting member 250 mounted on the frame 230 and passing through the positioning seat 240, and a reflector 260 fixed on one side of the positioning seat 240.

[0030] The collar 210 is used to install other components. Protrusions 211 are symmetrically fixed on the inner wall of the collar 210. Grooves 141 are symmetrically opened on the outer side of the rotating shaft 140. The protrusions 211 are fitted into the grooves 141, ensuring that while the collar 210 slides on the rotating shaft 140, the rotation of the collar 210 can drive the rotating shaft 140 to rotate synchronously.

[0031] The frame 230 is used to install the positioning seat 240. Rectangular holes 231 are opened on both sides of the frame 230. Side plates 243 are fixed on both sides of the positioning seat 240. The side plates 243 are slidably fitted into the rectangular holes 231 to limit the movement of the positioning seat 240 and ensure the stability of the positioning seat 240 within the frame 230.

[0032] The positioning seat 240 has a positioning hole 241 in the middle, which is used to guide and position the drilling position on the stator, so that the drill bit can drill according to the position given by the positioning hole 241.

[0033] The adjusting component 250 includes a threaded rod 251 rotatably mounted on the inner wall of the frame 230 with one end extending out of the frame 230, and a knob 252 fixed to the end of the threaded rod 251. The positioning seat 240 has a threaded hole 242 on its side. The threaded rod 251 passes through the threaded hole 242 and the two mesh with each other. With this arrangement, when the knob 252 is turned, the threaded rod 251 is driven to rotate. The threaded rod 251 rotates in the threaded hole 242, which drives the positioning seat 240 to move and adjust the position of the positioning seat 240.

[0034] The reflector 260 is fixed on the side plate 243 on one side of the positioning base 240. The ranging device 220 includes a distance display screen 221 fixed on one side of the collar 210 and a laser ranging sensor 222 fixed on one side of the distance display screen 221. The laser ranging sensor 222 corresponds to the reflector 260 and can monitor the position distance information of the positioning base 240 in real time. The distance display screen 221 is used to display the monitoring data of the laser ranging sensor 222 in real time.

[0035] The working principle and usage process of this utility model are as follows: In use, the stator is placed on the conical seat 110, with the central axis of the stator and the central axis of the sleeve 120 aligned vertically. The collar 210 is fitted onto the rotating shaft 140, ensuring the frame 230 is tightly against the top of the stator. Rotating the knob 252 causes the threaded rod 251 to rotate, which in turn moves the positioning seat 240. This movement of the positioning seat 240, in turn, moves the reflector 260. The laser range sensor 222 monitors the distance to the reflector 260 in real time, i.e., the distance between the positioning seat 240 and the center of the rotating shaft 140, and transmits this information. The distance is displayed on the distance display screen 221. When the displayed distance is equal to the set distance, stop rotating the knob 252. At this time, the positioning seat 240 is located at the drilling position on the stator. Align the drill bit with the positioning hole 241 on the positioning seat 240 to drill the stator. After drilling is completed, rotate the shaft 140 to drive the entire positioning mechanism 200 to rotate and drill other positions on the stator. At the same time, the angle sensor 150 monitors the rotation angle of the shaft 140 in real time and transmits it to the angle display screen 160 for display, so that the worker can determine the position of the next hole based on the included angle between the two holes on the stator.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
