Description

Technical Field

[0001] The invention relates to the field of assembly equipment, and in particular to a pressing assembly equipment and an assembly method for turbine nozzle processing. Background Art

[0002] The turbine nozzle is an important component of the turbine expander. It performs energy conversion in the flow section. In a reaction turbine expander, the expansion in the nozzle accounts for about 50% of the entire flow section. Therefore, a good design of the nozzle plays a vital role in improving the overall performance of the turbine expander. Turbine nozzles are widely used in various turbine machinery, such as steam turbines, gas turbines, etc.

[0003] The turbine nozzle is usually composed of an inner ring and an outer ring, between which a stator blade is installed, and a nozzle flow channel is formed between the stator blades. For example, in a nozzle structure for a throttling steam turbine, the outer ring surface of the inner ring has a number of evenly distributed stator blades, and a nozzle flow channel is formed between each two adjacent stator blades, so that the steam flow rate is higher. The inner ring of the nozzle is pressed and assembled in the outer ring of the nozzle, and the inner ring of the nozzle is overfitted with the outer ring of the nozzle, 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, wherein the electric push rod is arranged on the top of the base; a pressing mechanism, wherein the pressing mechanism is connected to the electric push rod on the top of the base; and a rotating mechanism, wherein the rotating mechanism is installed in the middle of the top of the base, wherein the rotating mechanism is connected to the pressing mechanism, and the valve body can be automatically placed in a placement rack, the ball body can be automatically pressed into the valve body, and the assembled ball valve can be automatically squeezed out of the placement rack, thereby reducing the workload of people and improving the efficiency of ball valve assembly. Chinese patent CN111085843B discloses an automatic oil seal assembly device for auto parts, including a pressing component, a pressing plate, a feeding component, and an engine rear end plate carrier. The pressing plate is controlled by a pressing electric screw rod, which is fixed on the top plate. Guide rods and guide sleeves are arranged around the top plate and are integrally connected to the base. The pressing plate is connected to the top rod of the pressing electric screw rod through a connecting block and is controlled to slide up and down to implement pressing. An oil seal pressing plate and an integrally connected oil seal pressure rod are also arranged at the bottom of the pressing plate. The feeding component includes an oil seal carrier, a front top cylinder, a grab cylinder, a clamping claw, and a sliding cylinder. The engine rear end plate carrier is fixed on the base and positioned by a positioning pin. A top matching component that is pressed and installed in cooperation with the oil seal pressure rod is arranged at the bottom. The automatic oil seal assembly device for auto parts controls the pressing plate to accurately press the oil seal to the matching position of the shaft hole of the engine rear end plate through the pressing component, and supplies the oil seal to the bottom of the pressing component through the feeding component, automatically loads, and has strong practicality.

[0005] The above patents and prior art also have the following defects: After the inner ring of the turbine nozzle is pressed and assembled into the outer ring of the turbine nozzle, the turbine nozzle needs to be transferred for the next step of processing and fixing, which needs to be fixed by welding or bolts. However, during the movement of the turbine nozzle, the turbine nozzle is prone to shaking and collision, which causes the inner and outer rings of the turbine nozzle to loosen easily, causing the inner and outer rings of the turbine nozzle to shift, and the inner and outer rings of the turbine nozzle are not positioned accurately, resulting in a decrease in the quality of the turbine nozzle after fixing.
