A kind of clamp base for clamping Compressor Set blast pipe
Technical field
The utility model relates to a kind of clamp base for clamping Compressor Set blast pipe.Belong to the welding tooling technical field.
Background technology
It is thin that the blast pipe of Compressor Set has a housing, the member complexity, and welding capacity is large, and therefore the characteristics that the dimensional requirement precision is high just need to reduce the modification in manufacturing process, especially welding deformation as far as possible.But its appearance and size is large, and welding capacity is large, in controlling welding process, easily distortion, on technique, be difficult to reach, and cost is large.The heat treatment meeting produces more large deformation in addition, need to be together with fixture heat treatment, Reducing distortion, for making deflection in the margin of tolerance, must avoid as far as possible the fixture distortion, blast pipe mouth of pipe in the process of clamping is fixed on the cylinder frock, and another is fixed on edge-on frock, and the temperature distortion amount that wherein reduces clamp base is particularly important.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, the clamp base for clamping Compressor Set blast pipe that deflection is little.
The technical scheme in the invention for solving the above technical problem is: should comprise the base body for the clamp base of clamping Compressor Set blast pipe, the housing of described base body is formed by the housing square tubes soldering, its design feature is: also comprise flange ring, strengthen square tube and strengthen cushion block, described flange ring is fixed on the base body, be fixed with some reinforcement square tubes in this flange ring, described reinforcement square tube is radial distribution in flange ring, and described reinforcement cushion block is arranged on the mouth of pipe place of housing square tube and is welded and fixed with the square tube inwall.The cylinder frock is to be fixed on to strengthen on square tube, the mouth of pipe of clamping final vacuum Guan Yiduan is fixed on flange ring, when heat treatment is heated, due to the setting of strengthening square tube, make the distortion of flange ring reduce, guarantee the precision of flange ring, during use, blast pipe is arranged on flange ring, therefore can guarantee the precision of blast pipe; The base housing that is arranged so that of strengthening cushion block can reduce deformation when heat treatment; And all adopt the flower weldering when welding, but not seal welding so both can guarantee base intensity, reduced again welding, reduced welding stress, and also when heat treatment, thermal current is convenient to circulation, is heated evenly, and can the expanded by heating distortion yet.
The utility model also comprises connecting plate, and described connecting plate is fixed on the junction of adjacent two housing square tubes on housing, and connecting plate is used for fixing edge-on frock, and housing is played to booster action.
The utility model also comprises stationary pipes, and described stationary pipes is fixed on the both sides of base body, is provided with the reinforcement cushion block in stationary pipes, and this reinforcement cushion block and stationary pipes inwall are welded and fixed.Stationary pipes is for the inclined support bar between firm banking and edge-on frock, and the non-deformability that is arranged so that stationary pipes of strengthening cushion block in stationary pipes is stronger, further guarantees precision.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, when heat treatment is heated, strengthen the deformation direction of square tube mainly at flange ring in the radial direction, therefore, the distortion of flange ring, mainly in the radial direction, therefore can not affect the flatness of flange ring, during use yet, blast pipe is arranged on flange ring, therefore can guarantee the precision of blast pipe; The base housing that is arranged so that of strengthening cushion block can reduce deformation when heat treatment; Connecting plate is used for fixing edge-on frock, and base is played to booster action.

The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1 to Fig. 4, the clamp base for clamping Compressor Set blast pipe in the present embodiment comprises base body 1, housing 11, housing square tube 12, flange ring 2, strengthens square tube 3, strengthens cushion block 4, connecting plate 5 and stationary pipes 6, and wherein housing 1 is welded by four housing square tubes 12.
In the present embodiment, flange ring 2 is fixed on base body 1, be fixed with some reinforcement square tubes 3 in this flange ring 2, strengthen square tube 3 and be radial distribution in flange ring 2, strengthening cushion block 4 is arranged on the mouth of pipe place of housing square tube 12 and is welded and fixed with housing square tube inwall, the cylinder frock is to be fixed on to strengthen on square tube 3, the mouth of pipe of clamping final vacuum Guan Yiduan is fixed on flange ring 2, when heat treatment is heated, due to the setting of strengthening square tube 3, make the distortion of flange ring 2 reduce, guarantee the precision of flange ring 2, during use, blast pipe is arranged on flange ring 2, therefore can guarantee the precision of blast pipe, the base housing 11 that is arranged so that of strengthening cushion block 4 can reduce deformation when heat treatment, and all adopt the flower weldering when welding, but not seal welding so both can guarantee base intensity, reduced again welding, reduced welding stress, and also when heat treatment, thermal current is convenient to circulation, is heated evenly, and can the expanded by heating distortion yet.
Connecting plate 5 in the present embodiment is fixed on the junction of adjacent two housing square tubes 12 on housing 11, and connecting plate 5 is for fixing edge-on frock, and housing 11 is played to booster action.
Stationary pipes 6 in the present embodiment is fixed on the both sides of base body 1, be provided with in stationary pipes 6 and strengthen cushion block 4, this reinforcement cushion block 4 is welded and fixed with stationary pipes 6 inwalls, stationary pipes 6 is for the inclined support bar between firm banking and edge-on frock, the non-deformability that is arranged so that stationary pipes 6 of the interior reinforcement cushion block 4 of stationary pipes 6 is stronger, further guarantees precision.
In addition, it should be noted that, the specific embodiment described in this specification, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification is only to the explanation of the utility model structure example.Allly according to the utility model patent, conceive equivalence variation or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
