Description
Technical Field
The invention relates to a clamping and sealing method of an ultrahigh vacuum degree exhaust device of a hemispherical resonator gyroscope, which is used for clamping and sealing a hemispherical resonator gyroscope after vacuum exhaust and belongs to the technical field of clamping and sealing of exhaust pipes of hemispherical resonator gyroscopes.
Background
And sealing off refers to a process of sealing off the exhaust pipe after the exhaust of the vacuum device is finished so as to separate the device from the exhaust system. Sealing off a vacuum device, wherein an exhaust pipe is made of glass and is generally sealed by melting (burning); for exhaust pipes that are metallic (typically oxygen-free copper), pinch sealing (individually also fused) is common. The clamping and sealing are realized by extruding and shearing the oxygen-free copper bar air pipe by using a special sealing and separating clamp (usually a manual steel shear, or a gear transmission or an oil pressure transmission). The existing equipment has the following problems that a part of gas is more or less mixed in the manufacturing process of the oxygen-free copper pipe, and when the clamping and sealing are carried out, if the clamping and sealing speed is too high, the gas released by the deformation of the oxygen-free copper pipe cannot be pumped out in time, the gas can permeate into a device, and the existing vacuum degree is damaged. The existing equipment adopts an electric oil pump combined manual clamp to clamp and seal, the pressure provided by the electric oil pump is large, the clamping and sealing time consumption of workers is extremely short, and the comparison test of slow clamping and sealing shows that the extrusion deformation of the copper pipe really releases gas in the process of clamping and sealing the oxygen-free copper pipe, and the vacuum degree is reduced by two orders of magnitude. If the clamping speed is too fast, the gas is not ready to be pumped out, and the gas can reduce the vacuum degree, thereby influencing the subsequent production work of the device. In addition, the clamping and sealing are carried out in a manual clamping mode, the situation that the front and the back of the clamping and sealing positions are inconsistent can occur, and therefore the production efficiency is greatly reduced.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the clamping and sealing method for the hemispherical resonator gyroscope ultrahigh vacuum degree exhaust equipment, which can realize the slow clamping and sealing of the exhaust copper pipe, ensure that the gas released by the deformation of the copper pipe is completely absorbed, and not influence the original vacuum degree of a device.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the clamping and sealing method of the hemispherical resonator gyroscope ultrahigh vacuum degree exhaust equipment comprises the following steps,
1) firstly, acquiring a clamping and sealing device for a hemispherical resonant gyroscope ultrahigh vacuum degree exhaust device;
2) then clamping an exhaust pipe of the hemispherical resonator gyroscope ultrahigh vacuum degree exhaust equipment for the first time by using a clamping device, and starting a vacuumizing device to suck gas released when the exhaust pipe deforms while clamping; when the exhaust pipe is clamped for the first time, the exhaust pipe is not clamped and broken;
3) when the vacuum degree reading of the vacuum pumping equipment is recovered to the normal reading, then carrying out next clamping on the exhaust pipe on the basis of the previous clamping according to the step 2);
4) and repeating the step 3) according to the preset clamping times until the exhaust pipe is cut off.
The clamping and sealing device is provided with two cutters, and when clamping is carried out, the exhaust pipe is positioned between the two cutters and is extruded and deformed by the two cutters and finally clamped and broken; each cutter is provided with an adjusting screw, and the adjusting screws on the two cutters are opposite; except for the last clamping, when the front clamping is carried out, the adjusting screws on the two cutters contact with the cutters before the cutters so as to leave a space between the cutters, and when the adjusting screws on the two cutters are mutually abutted, the clamping is in place; when the two cutters are clamped, the distance between the cutters is reduced relative to the previous cutter when the adjusting screws on the two cutters are in contact with each other by changing the length of the adjusting screws.
Compared with the prior art, the invention has the following beneficial effects:
1. the original clamping and sealing mode is that an operator holds a clamp in a hand mode and clamps and seals a device hung and sealed on a specific working table, but the device is distributed in a circumference mode, the clamping and sealing positions are not uniform and laborious each time under manual operation, and the clamping and sealing efficiency of the device is low. The clamping and sealing device can freely switch the angle of the slide rail and the position of the clamp on the slide rail, which is equivalent to changing the position of the clamp on the circumference and the radius of the circumference, so that an operator does not need to hold the clamp in the working mode, and the clamping and sealing device has a certain height, thereby ensuring the consistent position of clamping and sealing every time and greatly improving the working efficiency of the operator.
2. The original clamping and sealing mode utilizes an electric oil pump to connect a clamp, and the clamp is held by a hand to quickly complete clamping and sealing under the high pressure action of the electric oil pump, so that the hidden danger of shearing dislocation exists, the problem that gas released due to rapid deformation of a copper pipe cannot be pumped out is solved, and the existing vacuum degree can be damaged if residual gas enters a device. The invention realizes multiple times of clamping on the basis of the prior art, and after each time of clamping, the next time of clamping can be carried out until the vacuum degree registration is recovered to the normal registration, and after multiple times of operations, the gas released by the deformation of the copper tube can be completely absorbed, so that the original vacuum degree of the device is not influenced.
