The pressure welding device for the stator core of the generator exciter solves the problems that the stator core is difficult to be taken out after welding and the like, is greatly convenient for the stator core to be taken out, labor-saving, time-saving, stable in quality and fast, and is capable of improving the working efficiency.
Description
Technical field
The utility model relates to a kind of generator press welding device, relates in particular to a kind of generator exciter stator core press welding device.
Background technology
The general main structure of generator has iron core and coil, includes stator, rotor among the iron core, and exciter stator, exciter rotor.In unshakable in one's determination the manufacturing, especially stator core quality at first is the punching manufacturing to the motor influence greatly; Punching processing guarantees dimensional tolerance and burr requirement by punch die, laminates iron core by punching then, also is to guarantee inside and outside circle unshakable in one's determination by the iron core pressure mounting mold; Flute profile dimensional tolerance and perpendicularity requirement, it is unshakable in one's determination will laminating the back punching besides integrally welded, the traditional operation method is for adopting dead mandrel and groove plunger location; During lamination, the mandrel fit clearance is tight, and lamination is very time-consuming; Mandrel fit clearance pine, circle dimensional tolerance and perpendicularity require to be difficult to again guarantee in it.Adopted three slices watts of shape expanders afterwards, three slices watts by the screw rod circle in the extruding tensioner iron core of screwing, and the circle size reaches requirement in making; It is big to produce surface pressure when screwing extruding owing to screw rod; It is little to put forward power below, circle flare cone in very easy the making, circle dimensional tolerance and quality in the influence.After having press-fited, the electric welder is around welding unshakable in one's determination, and operation is extremely inconvenient, and time-consuming.Power line La Laila goes, and very easily wearing and tearing cause short circuit, hurt sb.'s feelings easily.After iron core had been welded, the unshakable in one's determination taking-up was difficult to, and labor strength is big, and manual operations is inconvenient, has a strong impact on product quality.
Summary of the invention
The purpose of the utility model is to provide a kind of generator exciter stator core press welding device; It is easy for installation that this device makes exciter stator pressure welding unshakable in one's determination, external pressure set sub pressure welding operation unshakable in one's determination; Solve punching closed assembly, the unshakable in one's determination taking-up and the big problem of the difficulty that is welded, it is big to solve labor strength, inconvenient during manual operations; Problems such as time-consuming and unshakable in one's determination pressure welding quality instability satisfy processing unshakable in one's determination and product requirement.
The utility model is realized like this; It comprises frame type support, jack, top board, push rod, circular top flitch, upper padding plate, annular backing plate, panel, movable panel, eccentric motion bar, it is characterized in that the bottom surface center of frame type support is connected with jack, and the output shaft of jack connects the top board center; The upper surface end of top board evenly is provided with several push rods; The push rod end is connected with the circular top flitch, and the upper surface of frame type support is provided with upper padding plate, and the upper surface of upper padding plate is placed with annular backing plate; The diameter of annular backing plate is slightly less than the diameter of punching; Be placed with several panels and a movable panel on the annular backing plate with one heart, movable panel connects eccentric motion bar, and the circular top flitch is near the punching edge.
The technique effect of the utility model is: 1. optimize the expander structure, and the trisection panel, two panels are fixed in the mandrel, and another is movable panel, and is back and forth movable through rotating eccentricity motion bar promotion activity panel.It is very time-consuming to have solved dead mandrel lamination first, and labor strength is big, inconvenient problem during manual operations; Second solved circle flare cone in three slices watts of very easy making of shape expander, circle dimensional tolerance and quality problems in the influence.2. the exciter stator iron core rotation liftout support that is welded is that a workbench is placed the pressure welding tire, and it is dull and stereotyped not occupy hydraulic press and workbench, can install everywhere with electric welding equipment, saves to take up an area of the space, reduces operation two-way time, is convenient to operation.3. employing thrust ball bearing, the big and rotation of load capacity when being convenient to welding unshakable in one's determination, rotate different azimuth weld seam and the welding at a place arbitrarily freely, avoid power line La Laila to go easy to wear hurting sb.'s feelings, and greatly handled easily is saved weld time.4. adopt the 16T jack structure, solve problems such as being difficult to taking-up after iron core has been welded, greatly convenient unshakable in one's determination the taking-up, saving of work and time improves work efficiency, and steady quality is quick.
Description of drawings

Fig. 2 is the vertical view of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2, the utility model realizes that like this bottom surface center of frame type support 1 is connected with jack 2; The output shaft of jack 2 connects top board 3 centers, and the upper surface end of top board 3 evenly is provided with several push rods 4, and push rod 4 ends are connected with circular top flitch 5; The upper surface of frame type support 1 is provided with upper padding plate 6; The upper surface of upper padding plate 6 is placed with annular backing plate 7, and the diameter of annular backing plate 7 is slightly less than the diameter of punching, is placed with several panels 8 and a movable panel 9 on the annular backing plate 7 with one heart; Movable panel 9 connects eccentric motion bar 10, and circular top flitch 5 is near the punching edge.During use, at first, the specified punching 12 of closed assembly in order, rotating eccentricity motion bar 10 through movable panel 9 tensioner punching internal diameters, inserts locating bar, shaping, and measurement size stays stacking factor, loads onto pressing plate 11, and the nut of screwing is depressed into size.By R gap slot unshakable in one's determination, be welded by different azimuth rotation.Postwelding, the rotating eccentricity motion bar inwardly contracts movable panel, unclamps nut, takes off top board, and turning handle rises the jack central shaft, through top board 3, push rod 4 effects, drives circular top flitch 5 iron core is ejected.Detect, get locating bar.Whole pressure welding process of assembling is compact in order, quick, and steady quality is safe and reliable.
