Description

TECHNICAL FIELD

[0001] The utility model relates to flat wire motor technical field, especially line material twist head end precision milling device. BACKGROUND

[0002] In the process of manufacturing flat wire motor, after inserting the clamping coil into the profiling tool, all the coils are inserted into the iron core as a whole, and are pressed into the corresponding design size, and before the subsequent flaring, twisting and welding processes, it is also necessary to ensure that the length of the twisted head end meets the needs of processing and production. In the prior art, two reverse rotations are often used to cut off, or a specific device is used to cut off in order. These processing methods can meet the production needs in general flat wire motor processes, but when producing Mini Pin flat wire motor, part of the port of the twisted head end needs to be reserved and cannot be cut off in order or in a whole circle. Therefore, a device capable of precise milling is urgently needed. UTILITY MODEL CONTENTS

[0003] The utility model aims at providing a kind of line material twist head end precision milling device to solve the problems existing in the prior art.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0006] The top of workbench is provided with second through-hole, and stator tooling is detachably installed in the second through-hole, so that the twisted head end to be milled is vertically arranged downward.

[0007] By adopting the technical scheme, the milling head and the milling cutter are provided with the first linear guide rail, the second linear guide rail and the third linear guide rail, so that the three-dimensional machining freedom is obtained while the precision is ensured, the milling cutter can be accurately moved to the port to be milled at the bottom of the stator tooling, and the milling cutter is milled one by one, and compared with the whole row or whole circle cutting, the machining mode is slightly slower in speed, but is high in adaptability, when the process is changed and some ports need to be reserved, only the program of the milling cutter needs to be changed, without the need of manufacturing new tools and the like.

[0008] In a further embodiment, the stator tooling comprises an upper positioning part, a middle positioning part and a lower positioning part;

[0009] A third through hole is arranged at the middle position of the top of the upper positioning part, a plurality of fourth through holes are arranged at the circumference of the top of the upper positioning part, the top ends of first limiting rods are fixed in the fourth through holes, and the middle positioning part is arranged at the bottom end of the upper positioning part.

Since the stator tooling needs to be moved to the assembly line by the grabbing device after milling, the lighter the weight of the stator tooling is, the more convenient the transportation is, and the less the power consumption is.

[0013] In a further embodiment, an eighth through hole is arranged at the bottom end of the containing disc, a plurality of containing openings are arranged at the circumference of the bottom of the containing disc, the containing openings are used for containing the twisted ends of wires, and a protection disc is arranged at the bottom of the lower positioning part.

[0020] By adopting the above technical scheme, the clamping device is used to cooperate with the through slot on the top of the positioning part of the stator tooling through the clamping jaw, so as to clamp and place the finished stator tooling on the assembly line.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. By arranging the milling head and the milling cutter, three-dimensional machining freedom is obtained while maintaining ultra-high precision, which enables the milling cutter to accurately move to the required port at the bottom of the stator tooling and mill each port one by one. Compared with the traditional whole row or whole circle cutting method, the production method is slightly slower, but is highly adaptable. When the process changes and some ports need to be retained, only the milling cutter operation program needs to be changed, without the need for complex re-manufacturing of tools, which effectively adapts to new machining processes.

[0023] 2. By the setting of the stator tool, the distance between the upper positioning part, the middle positioning part and the lower positioning part can be changed by the limiting rod, so that the stators with different lengths can be adapted, and a plurality of through grooves and through holes for positioning and weight reduction are distributed on each positioning part, since the stator tool needs to be moved to the assembly line by the grabbing device after milling, the lighter the weight of the stator tool during the whole transportation process, the more convenient the handling is, and the effect of convenient grabbing and effective power consumption reduction is achieved.

[0024] 3. By the setting of the grabbing device, the upper positioning part of the stator tool can be matched to clamp and place the machined stator tool on the assembly line. BRIEF DESCRIPTION OF DRAWINGS
