Description
Technical Field
The invention relates to a clamping and sealing method of hemispherical resonator gyro ultrahigh vacuum exhaust equipment, which is used for clamping and sealing a hemispherical resonator gyro after vacuum exhaust and belongs to the technical field of hemispherical resonator gyro exhaust pipe clamping and sealing.
Background
Sealing off refers to a process of sealing off the exhaust pipe after the vacuum device is exhausted, so that the device is separated from an exhaust system. Sealing off of the vacuum device is carried out in a glass way for the exhaust pipe, and a fusion sealing (burning sealing) way is generally adopted; for exhaust pipes which are metallic (typically oxygen-free copper), the use of a pinch seal (individually also useful for sealing) is common. The clamping and sealing is to use a special sealing and separating clamp (usually manual steel shears or gear transmission or oil pressure transmission) to squeeze and shear the oxygen-free copper exhaust pipe. 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 speed is too high, if the gas released by the deformation of the oxygen-free copper pipe is not pumped out, the gas can infiltrate into a device to destroy the existing vacuum degree. The existing equipment adopts an electric oil pump to combine a manual clamp for clamping, the pressure provided by the electric oil pump is high, the clamping time consumption of staff is extremely short, and the comparison test of slow clamping shows that the oxygen-free copper pipe is in the process of clamping, the extrusion deformation of the copper pipe is really released by gas, and the vacuum degree is reduced by two orders of magnitude. If the clamping speed is too high, the gases are not pumped out, which can reduce the vacuum and affect subsequent production of the device. In addition, the clamping is carried out in a manual clamping mode, the situation that the clamping positions are inconsistent can occur, and therefore production efficiency is greatly reduced.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the clamping method for the ultra-high vacuum exhaust equipment of the hemispherical resonator gyroscope, which can realize the slow clamping of the exhaust copper pipe, can ensure that the gas released by the deformation of the copper pipe is absorbed completely, and does not influence the original vacuum degree of a device.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the clamping and sealing method of the hemispherical resonator gyro ultrahigh vacuum exhaust equipment comprises the following steps,
1) Firstly, acquiring a clamping and sealing device for the hemispherical resonator gyro ultrahigh vacuum exhaust equipment;
2) Then, clamping the exhaust pipe of the hemispherical resonator gyro ultrahigh vacuum degree exhaust equipment for the first time by using a clamping device, and simultaneously starting the vacuum pumping equipment to pump gas released when the exhaust pipe is deformed; during the first clamping, the exhaust pipe is not clamped off;
3) When the vacuum degree indication of the vacuumizing equipment is restored to the normal indication, then the exhaust pipe is clamped for the next time on the basis of the last clamping according to the step 2);
4) And (3) repeating the step (3) according to the preset clamping times until the exhaust pipe is sealed.
The clamping and sealing device is provided with two cutters, and when clamping is performed, the exhaust pipe is positioned between the two cutters, and the two cutters squeeze the exhaust pipe to deform and finally clamp off; each cutter is provided with an adjusting screw, and the adjusting screws on the two cutters are opposite to each other; except for the last clamping, when the two cutters are clamped in each time, the adjusting screws on the two cutters are contacted before the cutters so that a space is reserved between the cutters, and when the adjusting screws on the two cutters are mutually abutted, the two cutters are clamped in place; during each clamping, the distance between the two cutters is reduced relative to the previous time by changing the length of the adjusting screw.
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, clamping and sealing are carried out on devices hung and sealed on a specific working table, but because the devices are circumferentially distributed, the clamping and sealing positions are not uniform and laborious every time under manual operation, and the clamping and sealing efficiency of the devices is low. The clamping and sealing device can randomly switch the angle of the sliding rail and the position of the clamp on the sliding rail, which is equivalent to changing the position of the clamp on the circumference and the circumference radius, so that an operator does not need to hold the clamp, and the clamping and sealing device has certain height, so that the consistent clamping and sealing position each time is ensured, and the working efficiency of the operator is greatly improved.
2. The original clamping and sealing mode utilizes an electric oil pump to connect with a clamp, and under the action of high pressure of the electric oil pump, the clamp is held by a hand to rapidly finish clamping and sealing, so that hidden danger of shearing dislocation exists, the problem that the gas released by rapid deformation of a copper pipe is not pumped out is solved, and the residual gas can destroy the existing vacuum degree if entering a device. According to the invention, multiple clamping is realized on the basis of the prior art, after each clamping, the next clamping can be carried out until the vacuum degree indication is restored to the normal indication, and the gas released by the deformation of the copper pipe can be ensured to be absorbed completely after multiple operations, so that the original vacuum degree of the device is not influenced.
