The invention discloses a detection device and method for accurately measuring the closing time of a steam extraction check valve, belongs to the technical field of valve detection, and aims to solve the problem that the valve closing time of the steam extraction check valve is not accurately measured. The device comprises a fixing support, a suction cup, an electromagnet and a crane, a steam extraction check valve and the fixing support are arranged on a supporting body, a fixed pulley is arranged on the fixing support, a mounting frame is connected with a valve body, an angle sensor, a first travel switch and a second travel switch are mounted on the mounting frame, a pointer shaft is connected with a valve rod, and the angle sensor makes contact with the pointer shaft. When the valve is closed, the swing rod makes contact with the second travel switch, one end of the steel wire rope is connected with the valve clack, the other end of the steel wire rope bypasses the fixed pulley and is connected with the suction cup, the crane is connected with the electromagnet, and the suction cup is attracted to or separated from the electromagnet. Opening and closing positions and time are measured through the timer and the data acquisition device, the assembling and testing method is simple, operation is easy and convenient, safety is high, and measured data are accurate.

This invention relates to the field of component assembly technology, specifically to a method for assembling a coolant pump and a gearbox. The assembly method uses an auxiliary tool, which includes a shaft with a boss at one end. A first limiting structure and a second limiting structure are provided on the outer circumference of the boss and the shaft, respectively. The assembly method is performed according to the following steps: S1, inserting the boss of the auxiliary tool into the coolant pump, thus securing the coolant pump to the tool; S2, holding the tool horizontally, inserting one end of the coolant pump bolt into the gearbox mounting hole, adjusting the tool to align the bolt with the screw hole in the gearbox; S3, after the bolt and screw hole are aligned, the second limiting structure confines the tool within the mounting hole, and a tightening gun is used to tighten the bolt from the coolant pump nut side, completing the assembly of the coolant pump and gearbox. This invention uses an auxiliary tool to tighten the coolant pump, facilitating the tightening of the coolant pump bolts with a tightening gun, preventing the coolant pump from shaking or rotating.

The present application discloses a wall-mounted base for an oscillating head machine and an assembly method thereof, and belongs to the technical field of oscillating head machine installation. A wall-mounted base for an oscillating head machine comprises a base body, a waist-shaped hole is provided at the bottom of the base body, a waist-shaped plate is provided on the inner side of the base body relative to the waist-shaped hole, and a gap is left between the waist-shaped hole and the waist-shaped plate for the screw head to pass through; steps are provided on both sides of the waist-shaped hole close to the waist-shaped plate, and when the base body and the screw are in an assembled state, the side of the screw head close to the screw tail abuts against the step, and the side of the screw head away from the screw tail abuts against the waist-shaped plate; the side of the step away from the end of the waist-shaped plate adopts an oblique transition. The wall-mounted base for an oscillating head machine and the assembly method thereof do not need to connect the oscillating head machine to the wall through a bracket, which simplifies the wall-mounted structure of the oscillating head machine, facilitates assembly, and ensures that the oscillating head machine is firmly fixed to the wall.

The invention belongs to the technical field of aircraft assembly and connection, and discloses an aileron clutch drilling device which can effectively guarantee the relative size of connecting holes in a left square support and a right herringbone support and can effectively guarantee the relative angle of the left square support and the right herringbone support of an aileron clutch assembly. And the assembly quality of the aileron clutch is improved. According to the connecting holes in the square support of the device, the connecting holes in the left side square support of the aileron clutch and the wing rear beam stand column are drilled, a positioning hole in the wing rear beam stand column is omitted, and the problem that the positioning hole in the left side square support of the aileron clutch and the positioning hole in the wing rear beam stand column are not concentric is solved. And meanwhile, the structural form of the device is superior to that of an aileron clutch product, the structural form is relatively open, a good construction path is provided, the construction difficulty is reduced, and the problem that the hole diameter is out of tolerance after a connecting hole of the aileron clutch left side support and a wing rear beam stand column is formed is completely eradicated.
