Abstract
The utility model discloses a novel welding bellows of high vacuum, including left flange, right flange and bellows, bellows coupling is between left flange and right flange, the bellows has cup jointed a plurality of installation cover, is equipped with first guide arm between two adjacent installation covers. The utility model discloses simple structure, the bellows can be followed first guide arm and second guide arm and slided in the axis direction, even ensure even if the subassembly still can freely move behind the both ends flange, ensured that the subassembly is after vacuum apparatus is advanced in the installation, can compensate because the position difference between the spare part that produces in equipment assembly error or the use, ensure that equipment can not lead to the damage of equipment because too big distortion in certain position moving range, the bellows can seal, after vacuum apparatus is advanced in the unit mount, can realize that the fluid of equipment passes through and can not reveal, realize sealing through the bellows.
Description
Technical Field
The utility model relates to a vacuum apparatus technical field especially relates to a novel welding bellows of high vacuum.
Background
The application of vacuum equipment is more and more extensive and popular with people, but still more imperfect places exist, for example, vacuum sealing in the prior art uses a plurality of sealing rings for sealing, the welding sealing performance is poor, and the sealing rings are damaged due to abrasion during mechanical movement, so that the using effect of products is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, and the novel welding bellows of a high vacuum that proposes, functions such as size removal compensation and mechanical seal can be realized to this bellows.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel welding bellows of high vacuum, includes left flange, right flange and bellows, the bellows coupling is between left flange and right flange, the bellows has cup jointed a plurality of installation cover, is equipped with first guide arm between two adjacent installation covers, and linear bearing has been cup jointed to the tip of first guide arm, and linear bearing's outer lane is connected with the installation cover, also installs linear bearing on the installation cover that is located limit portion, has inserted the one end of second guide arm in the linear bearing, and the other end and corresponding left flange and the right flange joint of second guide arm, and the tip of first guide arm and second guide arm all is equipped with stop device.
Preferably, the limiting device comprises a locking nut which is sleeved at the end parts of the first guide rod and the second guide rod in a threaded manner, an elastic washer is arranged between the locking nut and the linear bearing, and the elastic washer is sleeved on the corresponding first guide rod and the corresponding second guide rod.
Preferably, the first guide rod and the second guide rod are arranged in a staggered mode.
Preferably, the mounting sleeve is welded to the bellows.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the corrugated pipe, the first guide rod and the second guide rod are matched with each other, so that the position difference between parts generated in the process of using or assembling error of the equipment can be compensated, and the equipment cannot be damaged due to excessive distortion in a certain position movement range;
2. the bellows can be sealed, and when the assembly is installed in vacuum equipment, the fluid of the equipment can pass through without leakage, and the sealing is realized through the bellows.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the device comprises a left flange 1, a corrugated pipe 2, a first guide rod 3, a linear bearing 4, an elastic washer 5, a locking nut 6 and a right flange 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a novel welding bellows of high vacuum, including left flange 1, right flange 7 and bellows 2, bellows 2 is connected between left flange 1 and right flange 7, bellows 2 has cup jointed a plurality of installation cover, be equipped with first guide arm 3 between two adjacent installation covers, linear bearing 4 has been cup jointed to the tip of first guide arm 3, linear bearing 4's outer lane is connected with the installation cover, also install linear bearing 4 on the installation cover that is located limit portion, 4 interpolation of linear bearing have the one end of second guide arm, the other end and corresponding left flange 1 and right flange 7 of second guide arm are connected, the tip of first guide arm 3 and second guide arm all is equipped with stop device.
Stop device includes that the screw thread cup joints lock nut 6 at first guide arm 3 and second guide arm tip, and is equipped with spring washer 5 between lock nut 6 and linear bearing 4, and spring washer 5 cup joints on corresponding first guide arm 3 and second guide arm, avoids first guide arm 3 and second guide arm and installation cover to break away from to play fine connection effect.
The installation cover is connected with bellows 2 welded connection, and first guide arm 3 and second guide arm dislocation set improve the antitorque nature.
In the present case, bellows 2 can slide in the axis direction along first guide arm 3 and second guide arm, it can still freely move to ensure even if both ends flange connection back subassembly, it is after the vacuum apparatus is installed to have ensured the subassembly, can compensate because the position difference between the spare part that equipment assembly error or produced in the use, ensure that equipment can not lead to the damage of equipment because of too big distortion in certain position displacement range, bellows 2 can seal, after the vacuum apparatus is gone into in the subassembly installation, can realize that the fluid of equipment passes through and can not reveal, realize sealing through bellows 2.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
