Description

Technical Field

[0001] The utility model belongs to the technical field of fixed work jigs, and particularly relates to an anti-deformation work tool for welding a baffle module. Background Art

[0002] Combined heat and power generation is an efficient and energy-saving way of energy utilization. Specifically, fuel and air are input into a burner for mixing and ignition, and the chemical energy of the fuel is converted into electric energy and heat energy through a combustion reaction.

[0003] Among them, the ratio of fuel to air in the burner is the key to affecting the combustion energy efficiency. To control the speed of air entering the burner, baffles need to be set on the pipelines around the burner. The baffle is composed of several baffle modules. The baffle module includes a bottom plate A, side plates B, and partition plates C. As Figure 1 shown, the manufacturing method of the baffle module is to select a stainless steel plate with a thickness of 2 mm; cut the stainless steel plate into partition plates C and plates to be bent with certain dimensions; then bend the plates to be bent into a groove with a bottom plate A at the bottom and side plates B on both sides; finally, place the partition plates vertically into the groove and fix them by argon arc welding.

[0004] When welding the partition plate C and the bottom plate A, and when welding the partition plate C and the side plate B, the plates will undergo different degrees of welding deformation at the weld due to welding stress. Since there are partition plates inside to block, the welding deformation will expand outwards, resulting in the inability to guarantee the size of the baffle module, affecting the temperature of downstream equipment, and at the same time causing the actual size to deviate from the original design size, and problems such as inability to install will occur during installation. Content of the Utility Model

[0005] The utility model provides an anti-deformation work tool for welding a baffle module to solve the problem of welding deformation of the current baffle module.

[0006] To solve the above technical problems, the technical solution of the utility model is:

[0007] An anti-deformation work tool for welding a baffle module, the baffle module includes a bottom plate, two side plates, and two partition plates, the bottom plate and the two side plates are formed by bending, and the two partition plates are vertically welded on the bottom plate and the two side plates. The anti-deformation work tool includes a mounting plate, at least two groups of module clamping units arranged on the mounting plate, a power structure for driving the opening and closing action of one group of module clamping units, and a linkage structure acting between adjacent two groups of the module clamping units;

[0008] The module clamping unit includes a trapezoidal screw rod, a guide shaft, two connecting plates respectively fixedly connected to the left-handed flange and the right-handed flange of the trapezoidal screw rod, and a bearing fixing seat fixed on the mounting plate. The connecting plates are connected to the guide shaft through linear bearings. The end of the trapezoidal screw rod is rotatably connected to the bearing fixing seat, and the end of the guide shaft is fixedly connected to the bearing fixing seat. The connecting plates correspond to the partition plates of the baffle module in position.

[0009] Specifically, a hole is formed in the top of the connecting plate, and a reinforcing nut is spot-welded on the outer wall of the side plate where the hole is located. The reinforcing bolt is screwed into the reinforcing nut.

[0010] Specifically, a positioning member is fixedly connected to the end of the mounting plate.

[0011] Specifically, the positioning member is two angle bars perpendicular to the mounting plate, and one side plane of the angle bar faces the module clamping unit.

[0012] Specifically, the bearing fixing seat is provided with an upper hole with a wider inner diameter and a narrower outer diameter and a lower hole with a narrower inner diameter and a wider outer diameter. The rod end of the trapezoidal screw rod gradually extends outward to form a trapezoidal rod with gradually decreasing diameters. The trapezoidal rod passes through the upper hole, and the end of the guide shaft is inserted into the lower hole.

[0013] Specifically, the power structure includes a handwheel fixedly connected to one end of the trapezoidal screw rod.

[0014] Specifically, the linkage structure includes a synchronous pulley fixedly connected to one end of the trapezoidal screw rod and a synchronous belt connecting the two synchronous pulleys.

[0015] Specifically, the trapezoidal screw rod is provided with a left-handed thread and a right-handed thread. The left-handed flange includes a left flange and a left nut rotatably connected to the left flange. The left nut is connected to the rod body of the trapezoidal screw rod through the left-handed thread. The right-handed flange includes a right flange and a right nut rotatably connected to the right flange. The right nut is connected to the rod body of the trapezoidal screw rod through the right-handed thread.

[0016] The technical solution provided by the present invention has the following advantages compared with the prior art:

[0017] 1. The connecting plate abuts against the side plate and corresponds to the partition plate in position. During welding, the connecting plate blocks the welding stress that expands outward at the weld, that is, blocks the outward expansion of the plate body of the baffle module due to welding deformation, ensures the dimensional accuracy of the baffle module, ensures the smooth assembly of the baffle module, and also avoids temperature differences caused by unevenness after the partition plate is welded and deformed.

[0018] 2. The two connecting plates of the module clamping unit can be driven to move synchronously in opposite directions or in the same direction by rotating the trapezoidal screw rod, which is applicable to baffle modules of different widths, expanding the application range of the anti-deformation tooling.
