[0021] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0022] Example 1

[0023] like Figure 1 to Figure 2 As shown, this embodiment designs a simple bracket-type inspection fixture for a vacuum tank, which is used to detect the relative positions of the vacuum tank 1 and its accessories, so as to ensure that the size of the vacuum tank 1 and the installation position of the accessories meet the actual production requirements.

[0024] The vacuum tank 1 is a round tank structure. The accessories fixedly installed on the outer wall of the vacuum tank 1 include an external joint 11, a one-way valve 14 and a fixing bracket. A fixing hole is provided on the fixing bracket, and the fixing hole is used for external connection when the vacuum tank 1 is installed.

[0025] The apparatus comprises a gauge base and a limit table 21 installed on the upper surface of the gauge base, and the gauge base is in the shape of a rectangular or square plate. There are a plurality of limit tables 21, which are arranged at different positions of the gauge base to support the external joint 11, the one-way valve 14 or the fixed bracket, so as to support the vacuum tank 1 in a horizontal state; the top of each limit table 21 is provided with at least one of the alignment convex cap 33, the alignment hole 22 and the support surface 23, and the top of the limit table 21 can also be provided with two or three of the alignment convex cap 33, the alignment hole 22 and the support surface 23, and the alignment convex cap 33 and the alignment hole 22 are used to align with the fixed hole at the corresponding position; the support surface 23 is used for supporting or / and limiting the external joint 11, the one-way valve 14 and the fixed bracket.

[0026] The limiting platform 21 is connected to the inspection tool base by welding or detachably connected by bolts; the limiting platform 21 is in the shape of a polygonal column, a plate, a strip or a bend.

[0027] The above structure realizes the rapid positioning of the vacuum tank 1 and its accessories through the limit platform 21 and the alignment convex cap 33, alignment hole 22, support surface 23 and other structures arranged on the limit platform 21, so as to quickly judge whether the size of the vacuum tank 1 and the relative position of each accessory meet the use requirements, improve the inspection efficiency of the vacuum tank 1 before leaving the factory, and realize a simple and convenient inspection process.

[0028] When the size of the vacuum tank 1 is different, the size of the bracket-type simple inspection fixture 2 is also adjusted accordingly. When the position of the accessories of the vacuum tank 1 changes, the position of the limit platform 21 on the inspection fixture base should also be adjusted accordingly. Different layouts of the limit platforms 21 can be used to achieve rapid inspection of different vacuum tanks 1.

[0029] This embodiment takes the vacuum tank 1 of model H36-3541050BA as an example:

[0030] In the structure of the H36-3541050BA vacuum tank 1, an external joint 11 is arranged on the right end face, a fixed bracket arranged on the side of the tank wall is a lateral bracket 15 (lateral brackets 15 are arranged on opposite sides of the vacuum tank 1 respectively), a fixed bracket arranged on the left end face is a Z-shaped bracket 13, a one-way valve 14 is also arranged on the left end face, and a fixed bracket arranged on the upper side of the tank wall is a U-shaped bracket 12.

[0031] For the H36-3541050BA vacuum tank 1, a simple bracket-type inspection fixture 2 is designed, such as Figure 1 As shown:

[0032] The limiting platform 21 corresponding to the external joint 11 is in a strip shape and has a supporting surface 23 arranged on the top. When the lower surface of the external joint 11 is inclined, the supporting surface 23 is also an inclined surface.

[0033] The limit platform 21 corresponding to the one-way valve 14 is in the shape of a plate, and two supporting surfaces 23 are arranged on the top of the plate-shaped limit platform 21. One supporting surface 23 is flat to support the main part of the one-way valve 14. When the outlet of the one-way valve 14 is arranged vertically, the other supporting surface 23 of the plate-shaped limit platform 21 is inclined to support the outlet of the one-way valve 14.

[0034] The limit platform 21 corresponding to the lateral bracket 15 is prism-shaped, and the top surface of the prismatic limit platform 21 forms a supporting surface 23 to support the lateral bracket 15. An alignment convex cap 33 is arranged at the center of the top surface of the limit platform 21; the fixing hole arranged at the outer end of the lateral bracket 15 is vertically downward, and the alignment convex cap 33 can be inserted into the fixing hole of the lateral bracket 15 accordingly.

[0035] The limiting platform 21 corresponding to the Z-shaped bracket 13 is strip-shaped, and the fixing hole arranged at the outer end of the Z-shaped bracket 13 is arranged horizontally. The top of the strip-shaped limiting platform 21 is also provided with a horizontal alignment hole 22, which can overlap with the fixing hole of the Z-shaped bracket 13.

[0036] Each outer end of the U-shaped bracket 12 corresponds to a bent stopper 21. The opening of the U-shaped bracket 12 faces outward and the two outer ends are bent to be parallel to the vacuum tank 1. The upper end of the bent stopper 21 extends to the upper part of the vacuum tank 1 and extends to the oblique inner side of the bent part of the U-shaped bracket 12. The fixing hole on the U-shaped bracket 12 is inclined, and the alignment hole 22 at the upper end of the bent stopper 21 can overlap with the fixing hole of the U-shaped bracket 12.

[0037] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
