Definitions
- the invention relates to a slot punching system for manufacturing of stator and rotor sheets with a device for Interim alignment of the rotor in the stator laydown station.
- DE-A-38 41 926 and in DE-A-32 49 402 describes the manufacturing process in detail.
- the slot punching system according to the preamble of claim 1 is the DE-A-26 32 382.
- the slot punching system usually consists of 2 slot or Punching machines (so-called tandem system), stacking stations and a transport system arranged in the center of the system, e.g. designed as a turnstile.
- DE-A-38 41 926 has the actual groove and separating cut to content, while DE-A-32 49 402 deals with the Round transport busy and a solution to the central Setting the electro-magnetic bars to different Disc diameter shows.
- Axle hole Before the blanks are punched in the grooving machine, a precise hole is made in the center, the so-called Axle hole. This hole is used for receiving and Centering the blank during machining in the slot punching system.
- one or more grooves are introduced into the round blank. These grooves, hereinafter referred to as fixing grooves, must be in a precise location to the actually on the slot system generating stator and rotor slots. Positional deviations are only permitted in ⁇ m and the aim is a value of corresponds to the ideal deviation value of 0 mm. Instead of fixing grooves are other types, e.g. Drilling possible.
- the object of the invention is a tool-independent To create facility in which all technically meaningful Arrangements and numbers of fixing, stator and rotor slots can be positioned to each other. Where these Device preferred for grooving with mechanically driven Sub-device is used.
- This task is based on a slot punching machine the preamble of claim 1 by the characterizing Features of claim 1 solved.
- the inventive device for intermediate alignment Rotorronde pursues the idea of being completely flexible Handling this blank to adapt to an unchangeable Tool position.
- the basic idea of the invention is, for example, in the stator staging station into the stator push-off device with simple Means to integrate a facility through a precisely defined angular swiveling of the rotor blank, which for the next punching operation sets the required position.
- This swiveling takes place via a rotary drive e.g. With Angle of rotation encoder (program-controlled) or with fixed stops.
- the big advantage is that it is much simpler Execution of the rotor punching tools, which are no longer the are adapted to each slot position and are much more universal can be used for different rotors and useful numbers are.
- FIG. 1 The basic structure of a slot punching system for the production of stator and rotor laminations can be seen from FIG. 1 .
- this system consists of the blank or blank stacking 1, a blank or blank alignment station 2, a stator slot machine 3, a stator removal station 4 with rotor alignment device 5, a rotor slot machine 6 and a rotor removal station 7.
- Figure 2a - 2f shows an example of a round pass through the grooving machine.
- FIG. 2a The arbitrary position of the round blank in the stacking point 1 can be seen in FIG. 2a .
- Figure 2b shows the alignment of the circular blank in the alignment station 2.
- the outer groove or outer marking 10 has a precisely defined position with respect to the following stator groove on the automatic slot machine 3 and the position of the inner axle hole groove 11. The reason for this lies in the fact that when punching in a slot punching system, the first punched stator slot and the first punched rotor slot are not in alignment, as already described.
- the first grooves 12 and the separating cut 13 can be seen in FIG. 2c in accordance with the production on the stator automatic slot machine 3.
- FIG. 2d shows the finished stator sheet 14 in the stator laying station 4 with the circumferential groove indicated.
- the still not grooved rotor plate 15 must now be rotated through the angle ⁇ by the rotor alignment device 5. This measure then ensures the exact required insertion position in the automatic rotor grooving machine 6.
- the first rotor groove position to be produced is indicated by dash-dotted lines.
- Arrow 16 shows possible directions of the position correction.
- FIG. 2e shows the rotor blank in the position adapted in accordance with the tool position which is constant in the rotor-grooving machine 6.
- the finished rotor plate with indicated circumferential grooves is shown in Figure 2f .
- the angle ⁇ corresponds to the rotor groove division.
- This angle ⁇ is not equal to the pitch angle ⁇ of the Stator sheets.
- the correction angle ⁇ is a function The correction is made for ⁇ and ⁇ and depending on the amount clockwise or counterclockwise.
- the actually inventive rotor alignment device 5 shows Figure 3a. That from the stator slot machine with the help of the transport system 8 and the electro-magnetic bars 9 removed Stator rotor plate 14, 15 is placed on the stator depositing station 4 filed. During the pivoting of the transport system 8 is the stator repulsion device 17 with the rotor alignment device 5 by cylinder 19 from the work area, to avoid a collision. This booted up Location is not shown. After removing the stator rotor plate 14, 15 on the stator laying station 4 moves the Piston rod 20 of the cylinder 19 down the entire system 5, 17 until the push pins 18 on the stator 14 and the Place the rotor holder 21 on the rotor plate 15.
- electro-magnets 22 are attached, thereby creating a Safe takeover of the rotor plate after switching off the Electro magnetic bars 9 is guaranteed.
- the entire facility 5, 17 is connected in a fixed manner to the groove system via the holder 27.
- Cylinder 23 moves downward by the dimension "a” and the stator plate is repelled by the push-off pins 18, which are connected to the cylinder 23 by a bridge 24.
- the magnetic bars 9 move a small amount, for example 4 mm high. This situation is shown in Figure 3b .
- Figure 3c shows the pivoting of the rotor plate by the required angle ⁇ .
- cylinder 25 moves up by the amount "b", whereby the rotor plate is also raised by this amount.
- the cylinder 25 is operatively connected to the rotor holder 21, as indicated in principle in FIG. 3c.
- the pivoting device 26 pivots by the angle ⁇ .
- the rotor plate is then removed from the transport system 8 and the electro-magnetic rods 9 and the Stator repulsion device 17 with the rotor alignment device 5 is through the piston rod 20 in connection with the cylinder 19 moved out of the interference area of the transport system.
- the transport system now places the rotor plate in the correct position Rotor-Groove 6 on and after grooving it will finished rotor plate transported to the rotor placement station.
