Description
Technical Field
[0001] The utility model relates to the technical field of rubber ring pressing tools, in particular to a sealing ring pressing and filling device. Background Art
[0002] Current magnetron sputtering coating equipment usually uses a cylindrical cavity or a rectangular cavity, and the working environment is a high vacuum, which needs to reach 10 -4 Pa or 10 -5 Pa or above, and because of the need for injection or sampling, the end door of the chamber needs to be opened frequently. In general, the end door cannot be sealed with oxygen-free copper rings or silver wire metal seals, but with fluororubber rings. This sealing method requires digging a ring-shaped sealing groove on the surface of the end door, and then placing the O-type sealing rubber ring in the sealing groove. The sealing groove of this equipment usually adopts a dovetail sealing groove, which has a narrow upper and wide lower structure and has a good three-sided sealing effect. Because of the filling rate requirement, the spacing between the upper openings of the sealing ring groove must be smaller than the diameter of the sealing ring, and the sealing ring itself has a high hardness, so it is very difficult to put the sealing ring in, especially for thick rubber rings with a diameter of more than 7mm. It is a very difficult task to press the sealing ring into the sealing ring groove. It is necessary to apply vacuum grease and use objects such as round bars to squeeze hard, which is inefficient and requires a high level of hand strength for the operator; because it can only be installed by pure manual means, and the size and shape of the sealing ring are different, the depth of the sealing ring groove is also different, and the external equipment used for pressure filling is not standardized and uniform, and standardized operation cannot be formed. Therefore, a pressure filling tool is urgently needed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model aims to provide a sealing ring pressure filling device to solve the problems existing in the prior art, so as to improve the working efficiency of the sealing ring pressure filling and standardize the operation.
[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] like Figures 1 to 4 As shown: This embodiment provides a sealing ring pressing and filling device, including a fixed clamp 1 and a movable clamp 2, the middle parts of the fixed clamp 1 and the movable clamp 2 are hinged by a pin shaft 4, one end of the fixed clamp 1 is a handle 3, and the other end is provided with a plug plate 11, one end of the movable clamp 2 is a handle 3, and the other end is provided with a slot, the slot and the plug plate 11 are arranged oppositely, the plug plate 11 is used to fit the side wall of the sealing ring groove 5, and the slot is used to squeeze the sealing ring 6 into the sealing ring groove 5. The structure of this embodiment is similar to the hinged form of commonly used tools such as scissors and pliers.
[0027] As an optional solution, in this embodiment, the fixing pliers 1 are provided with a plurality of hinge holes 12 for the pin shafts 4. In this embodiment, three hinge holes 12 are provided, and the spacing between adjacent hinge holes 12 is 1 cm-6 cm. The shifting operation can be performed for sealing ring grooves 5 of different depths, so that the angle between the card slot and the lower plug plate 11 can be adjusted to adapt to the sealing rings 6 of different diameters when being pressed and filled, and the sealing ring 6 can be pressed in with force.
[0028] As an optional solution, in this embodiment, the pin 4 is fixedly connected to the side wall of the movable pliers 2 and can be formed into an integral part by welding. A latch is provided at the end of the pin 4 to prevent the hinge from being disengaged. The pin 4 can also be the pin 4, which is convenient for assembly with the fixed pliers 1.
[0029] As an optional solution, in this embodiment, a plurality of protrusions 21 are arranged at intervals on the movable clamp 2, and a clamping groove is formed between adjacent protrusions 21. The clamping groove has no side clamping on the sealing ring 6, and only lateral extrusion and forward extrusion are performed to avoid the sealing ring 6 from being stuck and not falling off.
[0030] As an optional solution, the protrusion 21 in this embodiment is hemispherical and the protrusion radius gradually decreases from the outside to the inside, and the spacing between adjacent protrusions 21 is 1cm-7cm. Among them, the hemispherical protrusion can adapt to O-rings with different diameters of 7mm to 13mm; the hemispherical protrusion part can be shifted by using different hinge holes 12, and then the hemispherical protrusion of suitable size can be selected to press the sealing ring 6, so as to facilitate the application of changing the filling angle when the sealing ring groove 5 has different widths and depths.
[0031] As an optional solution, the insert plate 11 in this embodiment is set at an angle of 65°-75° with the end of the fixing clamp 1, and can be set at about 68°. The part of the insert plate 11 protruding from the end of the fixing clamp 1 is in contact with the side wall of the sealing ring groove 5 and is used to receive the sealing ring 6. According to the design principle of the dovetail groove, the insert plate 11 has a certain bevel angle, preferably 70° in this embodiment. The angle between the inclined surface of the dovetail groove and the horizontal plane is usually required to meet the requirement that the sealing ring 6 can have 15-25% of the exposed part at the top after being placed in the dovetail groove. Therefore, the angle is generally fixed, about 70°, and even if there is a difference, the difference is not large, at most about 1-2°. Therefore, the insert plate 11 can be fixed to meet the requirements of different angles.
[0032] As an optional solution, in this embodiment, the thickness of the insert plate 11 is not greater than 0.2 mm and the length is not greater than the length of the side wall of the sealing ring groove 5. The insert plate 11 must be very thin to be inserted into the sealing ring groove 5 without affecting the filling of the rubber ring.
[0033] As an optional solution, the material of the fixed clamp 1 and the movable clamp 2 in this embodiment includes stainless steel, preferably 304 stainless steel, which is rust-proof and has good toughness and a certain degree of deformation resistance.
[0034] As an optional solution, in this embodiment, the handles 3 of the fixed pliers 1 and the movable pliers 2 are both provided with rubber sleeves 31, and the rubber sleeves 31 are provided with anti-slip textures or protrusions to increase the friction of the palm holding, facilitate strong pressing and prevent slipping.
[0035] As an optional solution, in this embodiment, the length of the fixed clamp 1 and the movable clamp 2 is at least 13 cm.
[0036] The sealing ring filling device of the present embodiment is a handheld filling tool that can help installers to quickly and conveniently fill vacuum sealing rings 6, especially sealing rings 6 of different dimensions, lengths, and thicknesses. When the diameter of the sealing ring 6 is larger than the external opening size of the dovetail sealing ring groove 5, the ordinary manual filling method requires the installer to apply a large amount of vacuum grease, and then squeeze the sealing ring 6 into the groove by force or use a stainless steel plate to roll the sealing ring 6, which is still very laborious. After using the manual filling tool of the present embodiment, vacuum sealing rings 6 with higher hardness can be filled efficiently and quickly, especially for large-sized hard vacuum sealing rings 6 with a diameter of more than 8 mm. It has a very good filling effect, and the efficiency is greatly improved compared to pure manual pressing. It is also suitable for the construction of other professional special tools similar to sealing rings 6.
[0037] This specification uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core idea of the utility model. At the same time, for those skilled in the art, according to the idea of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
