Description

Tool for rapidly identifying color and groove number of three-phase line

Technical Field

The utility model relates to a PMSM technical field specifically is a frock of quick discernment three-phase line colour and groove number.

Background

The new energy automobile industry is an industry for the future key planning and support of the country, one of core technologies of the new energy automobile is the design and manufacture of a driving motor, and the core of the driving motor is the design and manufacture of a stator winding, so the design and manufacture of the stator winding determines the overall performance (including output power, NVH, service life and the like) of the driving motor and the whole automobile.

At present, most of domestic motor suppliers basically manufacture stator windings manually or semi-automatically, the overall efficiency and the yield are low, the manufacturing cost of motor manufacturers is high, and the competitiveness and the occupancy of the domestic motor suppliers on the market are gradually reduced.

The defects and shortcomings of the prior art are as follows:

the three-phase wire wiring and outgoing of the stator winding of the permanent magnet synchronous motor of the new energy automobile basically comprises the steps of finding out the number of grooves needing outgoing by manual visual methods, then sleeving sleeves with corresponding colors, wherein most iron cores are divided into 48 grooves, 96 grooves and the like, so that 12 or 24 groove wire bundles of the three-phase wires need to be manually arranged, each groove wire bundle also needs to be manually sleeved with insulating sleeves with three different colors and four different lengths, the whole winding can be directly scrapped due to the fact that one groove wire bundle is staggered or one groove is staggered with the sleeves with different color wire bundles, the skill requirement on operators is very high, and therefore the probability of products being scrapped by mistake is very high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a quick frock of discernment three-phase line colour and groove number to solve the problem of mentioning among the above-mentioned background art.

The utility model provides a frock of quick discernment three-phase line colour and groove number, includes A frock, B frock and magnet, A frock and B frock are the semicircle ring structure, and the inboard equidistance of A frock and B frock is inlayed and is had a plurality of magnets, and it is equipped with a plurality of protrusion structures still to go back the equidistance on the outer circumference of A frock and B frock, and the inboard of A frock still is equipped with the navigation key.

Preferably, the A tool is connected to one side of the iron core through the matching of a positioning key and a positioning groove in the iron core, the original point of the A tool is positioned on the iron core of the product, and the B tool is adsorbed to the other side of the iron core through a magnet.

Preferably, the raised structures are identified by three colors of cyan and yellow and four numbers of 1-4.

Preferably, the tool A and the tool B are made of aluminum alloy materials, and each side of the tool A and each side of the tool B are subjected to rounding treatment.

The utility model has the advantages that: adopt magnet absorption formula and keyway locate mode location product original point, the mistake proofing is and efficient. The frock material adopts aluminum alloy material manufacturing to all make the fillet structure on all sides, fatigue strength and the risk of damaging the product when can effectively reducing the staff and repeatedly take. The circular protruding part structure on the tool structure is marked by three different colors and 1-4 numbers so as to represent the color of the wire harness sleeve to be sleeved and the length of the sleeve of the winding corresponding to the number of the slots, and the operation can be rapidly and correctly carried out. Meanwhile, the skill requirement of operators can be reduced, and the purpose of meeting the requirement of post installation can be achieved through simple training.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

The utility model provides a frock of quick discernment three-phase line colour and groove number, includes A frock 1, B frock 2 and magnet 3, A frock 1 and B frock 2 are semicircle ring structure, and the inboard equidistance of A frock 1 and B frock 2 inlays and have a plurality of magnet 3, and it is equipped with a plurality of protrusion structures 5 still to descend the equidistance on the outer circumference of A frock 1 and B frock 2, and the inboard of A frock 1 still is equipped with navigation key 4.

In this embodiment, a frock 1 passes through the constant head tank 6a cooperation fixed connection on iron core 6 of navigation key 4 and iron core 6 on one side, and its initial point location is on product iron core 6, and B frock 2 passes through magnet 3 and adsorbs on the opposite side of iron core 6. Adopt magnet absorption formula and keyway locate mode location product original point, the mistake proofing is and efficient.

In this embodiment the protruding structures 5 are identified by three colours of cyan and yellow and four numbers of 1-4. The projecting structure 5 is marked by three different colors and numbers 1-4 to indicate the color of the sleeve to be sleeved and the length of the sleeve to be sleeved of the wiring harness with the number of the corresponding slots of the winding, so that the operation can be quickly and correctly carried out.

In this embodiment, the tool a 1 and the tool B2 are made of an aluminum alloy material, and each side of the tool a 1 and the tool B2 is rounded. The fillet treatment can effectively reduce the fatigue strength and the risk of damaging the product when the staff repeatedly take.

The working process and the principle thereof are as follows:

this frock comprises A

frock

1 and 2 two parts of B frock, and A frock 1 and B frock 2 are the semicircle ring structure, and the inboard equidistance of A frock 1 and B frock 2 is inlayed and is had a plurality of magnets 3, and the inboard of A frock 1 still is equipped with navigation key 4.
