[0002] Before the generator stator core is put into production and embedded wires, it is necessary to check the dimensions of the stator core (including: core length, core outer diameter, core inner diameter, end face flatness, inner hole verticality, inner hole Whether it is flat and skewed, etc.) to carry out a complete inspection, so as not to cause unqualified iron cores to flow into production, resulting in failure to produce, or the performance of the generator is not up to standard, or even scrapped
[0003] At present, although there are many processes and tools used for the inspection of the stator core of the generator, it is still not possible to complete the inspection. Some dimensions are still difficult to inspect and the inspection is not in place.
As a result, some unqualified stator cores flow into production

Embodiment Construction
[0017] see figure 1 and figure 2 As shown, a small generator stator core inspection device 100 includes a rotating disk 1, a positioning block 2, a sleeve 3, a base 4, a positioning sleeve 5, a vertical bar 6, a horizontal bar 7, A depth gauge 8, a rotating shaft 9, a bearing 10 and a dial indicator 11.
[0018] see again Figure 1-4 , the rotating disk 1 has a stepped groove 101 and a housing portion 102, the stepped groove 101 is set around the periphery of the housing portion 102; The side wall 104 on the outer edge of the disc 103, the upper end of the side wall 104 is sunken downwards to form the stepped groove 101; the side wall 104 is evenly arranged with four openings 105, which is more convenient for the operator to dispose of the iron. Placement of core 12. The positioning block 2 is suspended in the accommodating portion 102, and the positioning block 2 includes a small-diameter section 21 and a large-diameter section 22 arranged from top to bottom, and the sle...

The invention provides a verifying device for a small-size generator stator core. The verifying device comprises a rotating disk, a positioning block and a sleeve, wherein a stepped slot and an accommodating part are formed on the rotating disk; the stepped slot is annularly formed in the outer periphery of the accommodating part; the positioning block is suspended in the accommodating part; the positioning block comprises a small-diameter section and a big-diameter section which are arranged from top to bottom; the sleeve is sleeved on the small-diameter section; a bottom end of the sleeve is arranged on the big-diameter section; the sleeve is in fastening connection with the big-diameter section; the outer diameter of the sleeve is equal to the outer diameter of the big-diameter section; and in a working state, a stator core is sleeved in the sleeve and is in clearance fit with the sleeve, and the bottom end of the stator core is resisted against the interior of the stepped slot. The verifying device provided by the invention has the advantages of simple structure, convenience in operation and capability of perfectly verifying the sizes of all the items of the generator stator core.
Description
technical field [0001] The invention specifically relates to an inspection device for a stator iron core of a small generator. Background technique [0002] Before the generator stator core is put into production and embedded wires, it is necessary to check the dimensions of the stator core (including: core length, core outer diameter, core inner diameter, end face flatness, inner hole verticality, inner hole Whether it is flat and skewed, etc.) to carry out a complete inspection, so as not to cause unqualified iron cores to flow into production, resulting in failure to produce, or the performance of the generator is not up to standard, or even scrapped. [0003] At present, although there are many processes and tools used for the inspection of the stator core of the generator, it is still not possible to complete the inspection. Some dimensions are still difficult to inspect and the inspection is not in place. As a result, some unqualified stator cores flow into production...
