Background technology
Development along with nuclear power technology, performance requirement for motor is also more and more higher, ensure that motor is properly functioning and need exist for efficient cooling system, by installing the mode of cooling water jecket on motor casing flange excircle surface, it is possible to solve the heat dissipation problem of motor casing flange well.
In prior art, as the large cylinder-shaped workpiece such as above-mentioned large-size machine cooling water jecket processing and assembling time, existing fitting device is difficult to control the workpiece deflection when welding processing, the excircle of workpiece after swelling is very easily caused to beat and be unable to reach designing requirement, particularly with above-mentioned large-size machine cooling water jecket, owing to the water channel on chuck and two ends end ring welding amount are big, it is easier to be deformed.
Summary of the invention
The goal of the invention of the present invention is in that to provide a kind of fitting device for large cylinder-shaped work pieces process and assembling, it is possible to effectively solves workpiece and is deformed problem when welding processing.
The object of the invention technical scheme is: a kind of fitting device for large cylinder-shaped work pieces process and assembling, mandrel is connected fixing with spacing base, outside the upper end of mandrel, lower end outside is equipped with end plate, end plate is along the circumferential direction provided with multiple swelling device, swelling device includes voussoir guide pad and fan-shaped pressing plate, it is bolted between voussoir guide pad and fan-shaped pressing plate, bolt is cased with stage clip, fan-shaped pressing plate can radially do stretching motion, swelling device also includes voussoir, voussoir is between fan-shaped pressing plate and voussoir guide pad, voussoir is by vertically arranged voussoir bolt, nut and end plate are fixed, it is round table-like that end plate is two grades of stairsteppings, the outside of voussoir guide pad is curved, fit with the minor diameter frustum cone side of end plate, the major diameter round platform horizontal plane of voussoir guide pad and end plate is fixed, sliding shim it is provided with between nut and end plate, thrust cover it is provided with outside sliding shim, fan-shaped pressing plate, voussoir guide pad and wedge surface carry out chromium plating process, and base is provided with support column.
The invention have the benefit that
The present invention is along the circumferential direction provided with multiple swelling device on the end plate of mandrel, and the fan-shaped pressing plate of swelling device can coordinate the processing of workpiece to carry out radial expansion, and the voussoir of swelling device can realize the Anti-deformation support to workpiece.The present invention is when for large cylinder-shaped workpiece welding processing such as large-size machine cooling water jeckets, and work pieces process is unlikely to deform, and after effectively solving workpiece swelling, workpiece barrel cylinder degree is low, and cylindrical is beated big problem. The present invention can realize the series of processes such as the internal jacket processing of large-size machine cooling water jecket, water channel welding, the processing of water channel postwelding, external jacket hot jacket, end ring welding, efficiently solves the problem that large-size machine cooling water jecket frequently changes instrument in different operations. The present invention, by changing fan-shaped pressing plate and the applicable various sizes of work pieces process of voussoir, can effectively reduce processing cost. The present invention is by unclamping the nut coordinated with voussoir bolt, and fan-shaped pressing plate can bounce back, the dismounting of convenient fitting device. The fan-shaped pressing plate of swelling device of the present invention, voussoir guide pad and wedge surface carry out chromium plating process, more extend the service life of instrument.

Detailed description of the invention
As it is shown in figure 1, mandrel 2 is connected fixing with spacing base 3, as Figure 1 and Figure 4, outside the upper end of mandrel 2, lower end outside be equipped with end plate 2b, end plate 2b is along the circumferential direction provided with multiple swelling device 1, in the present embodiment, end plate is along the circumferential direction provided with 6 swelling devices.
As shown in Fig. 2, Fig. 3, Fig. 5, swelling device includes being connected by bolt 1h between voussoir guide pad 1b and fan-shaped pressing plate 1a, voussoir guide pad 1b and fan-shaped pressing plate 1a, and bolt is cased with stage clip, and fan-shaped pressing plate 1a can radially do stretching motion. Fan-shaped pressing plate 1a swelling workpiece diameter size as required is processed, to reach the purpose fitted completely under swelling state with workpiece. Swelling device also includes voussoir 1c, voussoir 1c between fan-shaped pressing plate 1a and voussoir guide pad 1b, and voussoir 1c is fixed by vertically arranged voussoir bolt 1d, nut 1e and end plate 2b. It is round table-like that end plate 2b is two grades of stairsteppings; The outside of voussoir guide pad 1b is curved, fits with the minor diameter frustum cone side of end plate 2b, and the major diameter round platform horizontal plane of voussoir guide pad 1b and end plate is fixed. The arc size of voussoir guide pad 1b processes according to excircle dimension D2, D4 of mandrel 2, it is desirable to contact surface can be fitted very well. It is provided with sliding shim 1f between nut 1e and end plate, outside sliding shim 1f, is provided with thrust cover 1g. Sliding shim 1f adopts pyrite as material, and nut 1e is carrying out can playing in high torque screwing operations the effect of minimizing frictional force. Fan-shaped pressing plate 1a, voussoir guide pad 1b and voussoir 1c surface carry out chromium plating process, can effectively increase the service life. Base is provided with support column 4.
During installation, first mandrel and base are attached by bolt. Then, mandrel end plate is along the circumferential direction uniformly installed 6 swelling devices. When swelling device is installed, first voussoir guide pad is connected with fan-shaped pressing plate, overlapping compression spring on bolt, bolt need not install tension, and fan-shaped pressing plate should reserve certain stroke, the degree of depth that screws of bolt can be adjusted stroke according to actual needs, then, wedge shape guide pad and mandrel end plate bolt are fixed, then voussoir bolt, voussoir, nut, sliding shim are sequentially carried out connection, finally, thrust cover is arranged on mandrel end plate.
Vertical car is measured the outside diameter runout of large cylinder-shaped workpiece, the medium-and-large-sized cylindrical workpiece of the present embodiment is large-size machine cooling water jecket, by adjusting the nut in swelling device, chuck outside diameter runout is adjusted in the scope allowed, thus the fixing operation of swelling completing chuck, by vertical Vehicle Processing cylindrical, wheel carrier carries out cooling water channel welding, postwelding car water channel cylindrical, hot jacket external jacket, welding end ring, all process steps all can carry out on the apparatus.
