Description

Technical Field

[0001] This invention relates to the field of assembly equipment, and particularly to a press assembly device and an assembly method for turbine nozzle processing. Background Technology

[0002] Turbine nozzles are an important component of turbine expanders. They perform energy conversion in the flow passage. In reaction turbine expanders, the expansion within the nozzle accounts for about 50% of the entire flow passage. Therefore, good nozzle design plays a crucial role in improving the overall performance of turbine expanders. Turbine nozzles are widely used in various turbine machinery, such as steam turbines and gas turbines.

[0003] Turbine nozzles typically consist of an inner ring and an outer ring, with stator vanes installed between them, forming a nozzle flow channel. For example, in a nozzle structure for a throttling turbine, the outer surface of the inner ring has several evenly distributed stator vanes, with a nozzle flow channel formed between each pair of adjacent stator vanes, resulting in a higher steam flow rate. The inner ring of the nozzle is pressed and assembled inside the outer ring, with an overfit between the inner and outer rings, and then fixed by bolts or welding.

[0004] Chinese patent application CN111774844A discloses a ball valve press-type assembly device, comprising: a base and an electric push rod, the electric push rod being provided on the top of the base; a pressing mechanism connected to the side of the top of the base near the electric push rod; and a rotating mechanism installed in the middle of the top of the base, connected to the pressing mechanism. This device can automatically place the valve body into the placement rack, automatically press the ball into the valve body, and automatically expel the assembled ball valve from the placement rack, thereby reducing workload and improving ball valve assembly efficiency. Chinese patent CN111085843B discloses an automatic oil seal assembly equipment for automotive parts, including a pressing assembly, a pressing plate, a feeding assembly, and an engine rear end plate carrier. The pressing plate is controlled by a pressing electric screw, which is fixed to a top plate. Guide rods and sleeves are provided around the top plate and are integrally connected to the base. The pressing plate and the top rod of the pressing electric screw are connected by a connecting block and controlled to slide up and down to perform pressing. An oil seal pressure plate and an integrally fixed oil seal pressure rod are also provided at the lower part of the pressing plate. The feeding assembly includes an oil seal carrier, a front top cylinder, a gripping cylinder, a clamp, and a sliding cylinder. The engine rear end plate carrier is fixed on the base and positioned by a positioning pin. A top assembly is provided at the lower part to cooperate with the oil seal pressure rod for pressing and installation. This automatic oil seal assembly equipment for automotive parts controls the pressing plate to accurately press the oil seal to the shaft hole position of the engine rear end plate through the pressing assembly, and supplies the oil seal to the lower part of the pressing assembly through the feeding assembly, which is automatic and highly practical.

[0005] The aforementioned patents and prior art also have the following defects: After pressing and assembling the inner ring of the turbine nozzle into the outer ring, the turbine nozzle needs to be transferred for further processing and fixing. This requires welding or bolts for fixation. However, during the movement of the turbine nozzle, it is prone to shaking and collision, which can cause the inner and outer rings to loosen and shift. This inaccurate positioning of the inner and outer rings leads to a decrease in the quality of the turbine nozzle after fixing. Furthermore, collisions can easily cause wear and damage to the turbine nozzle, reducing the yield rate.

The clamps hold the nozzles, and the spacers support the next nozzle. This ensures that there are spacers between the nozzles in the fixed cylinder, preventing friction between the nozzles when they are moved. The nozzles are fixed in the fixed cylinder by the clamps, preventing them from moving. During the movement of the nozzles, they will not collide, thus protecting them and improving their quality. This ensures that the inner and outer rings of the assembled nozzles will not shift, guaranteeing assembly accuracy. 2.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Reference Figures 1-12The press assembly device shown includes an assembly table 1, on which a press component 2, a horizontal moving component 3, a clamping component 4 and a storage component 5 are provided. The clamping component 4 is installed at the bottom of the press component 2, and the press component 2 is installed on the horizontal moving component 3. The horizontal moving component 3 can drive the press component 2 to move horizontally, and the press component 2 can drive the clamping component 4 to move vertically. The assembly table 1 is also equipped with a pushing component 6. The storage component 5 includes a fixed cylinder 51, a storage cylinder 52 and several vertically arranged storage units 53.

The horizontal moving component 3 moves the pressing component 2 horizontally, and the pressing component 2 moves the clamping component 4. 4. Move the nozzle to the storage component 5 position. Press component 2 moves the clamping component 4 downward. The clamping component 4 moves the nozzle into the fixed cylinder 51. When the nozzle moves to abut against the partition 531 in the fixed cylinder 51, the clamping component 4 releases the clamp on the nozzle. The nozzle is placed on the corresponding partition 531. Push component 6 pushes the fixed cylinder 51 into the storage cylinder 52 a specified distance, so that the partition 531 and clamp 532 above the nozzle in the fixed cylinder 51 move. The clamp 532 moves to clamp this nozzle, and the partition 531 moves to place the next nozzle.

[0025] The assembled nozzles can be placed in the storage cylinder 52. After each nozzle is placed, the fixed cylinder 51 is moved a specified distance into the storage cylinder 52, causing the spacer 531 and clamping plate 532 above the nozzle to move. The clamping plate 532 holds the nozzle, and the spacer 531 supports the next nozzle. The nozzles in the fixed cylinder 51 are separated by the spacer 531, so that the nozzles will not rub against each other when moving. The nozzles are fixed in the fixed cylinder 51 by the clamping plate 532, so that the nozzles cannot move. During the movement of the nozzles, the nozzles will not collide, which improves the protection of the nozzles, improves the quality of the nozzles, and ensures that the inner and outer rings of the assembled nozzles will not be displaced, thus ensuring the accuracy of the assembly.

The extrusion block 533 drives the extrusion rod 534 to move into the fixed cylinder 51. At the same time, the extrusion block 533 compresses the return spring 535. The extrusion rod 534 drives the partition 531 and the clamping plate 532 to move. The partition 531 is used to support the next nozzle, and the clamping plate 532 clamps the nozzle located in the fixed cylinder 51.

[0028] When it is necessary to remove the nozzle, remove the fixing cylinder 51 from the storage cylinder 52, the return spring 535 returns to its original position, which in turn drives the squeezing block 533, the partition 531 and the clamping plate 532 to return to their original positions, releasing the clamp on the nozzle and allowing the nozzle to be removed.

The pushing component 6 pushes the fixed cylinder 51 into the storage cylinder 52 a specified distance, causing the partition 531 and clamping plate 532 located above the nozzle in the fixed cylinder 51 to move. The clamping plate 532 moves to clamp this nozzle, and the partition 531 moves to place the next nozzle.
