The specific embodiment
For having clear more and comprehensively understanding, now contrast the description of drawings specific embodiment of the present utility model to feature, the effect of sole bar reinforcement apical organ of the present utility model and the technical purpose that will reach.
Embodiment 1
As shown in Figures 1 to 3, the sole bar reinforcement apical organ 1 that the utility model proposes, has the arc top board 11 that at least one pair of is oppositely arranged, the all outstanding laterally arch shape that is of this a pair of arc top board 11, and the both ends of every pair of arc top board length direction are combined as a whole, and be provided with support 13 at these both ends, one screw rod 2 runs through the middle part of the two arc top boards 11 that are oppositely arranged, one end of described screw rod 2 is replaced the outer surface at an arc top board 11, one briquetting 3 has internal thread, be located on the other end of described screw rod 2, described briquetting 3 is resisted against the outer surface of another arc top board 11.For the displacement that makes arc top board 11 bigger, this screw rod 2 is run through peak 12 places that are arranged at arc top board 11 middle parts that are oppositely arranged, and an end of described screw rod fixes with the outer surface that is positioned at an outside arc top board 11, thereby when rotation briquetting 3, avoid screw rod together to rotate, can as early as possible described arc top board 11 be depressed into desired position by briquetting 3.
Described support 13 constitutes with the end one of arc top board 11, as can being that all-in-one is processed into, or by casting, forge and be made into integration, also 13 welding of described support can be arranged on the both ends of described arc top board 11.
For the ease of maintenance, replacing, described support 13 can also be the end that is removably mounted on arc top board 11, so in use can select support 13 with matching according to the component shape of institute's support.
Sole bar reinforcement apical organ of the present utility model, more convenient in order in use to adjust, on described briquetting 3, be provided with a spanner 4.
In the present embodiment, as Fig. 1,2,3,5A, 5B, 6A, the two-way sole bar reinforcement apical organ of 6B for constituting by two pairs of arc top boards.Described two-way sole bar reinforcement apical organ is mainly used in the support square cross, and wherein two pairs of arc top board angles can be adjusted with the workpiece shape, can be used for support and have arc-shaped inner surface, become workpiece at any angle.Fig. 5 A, 5B represent the square orthodrome workpiece of support, and Fig. 6 A, 6B represent the square little circular arc works of support, and the support position generally is the diagonal position place of workpiece.
Wherein, the state when the sole bar reinforcement top board 11 of Fig. 1,2, two pairs of equal in length of 3 expressions is in 90 ° of positions, the both ends of described arc top board 11 are provided with circular arc support 13, constitute two-way orthodrome support device.
The utility model is normally assembled like this, to on the following arc top board 11 the plug welding hole be set, by plug welding upper and lower two arc top boards 11 are combined into the arc of one group of sealing, and for the support 13 that is wholely set, with the circular arc position postwelding polishing of its end.After spanner 4 and briquetting 3 be welded as a whole, as shown in Figure 1, described spanner 4 and briquetting 3 are placed the top of upper arcuate top board 11 and be combined into sole bar reinforcement apical organ of the present utility model with screw rod 2 threaded engagement that are located on the upper and lower arc top board 11.
Operation principle of the present utility model is, according to the Hooke's law in the mechanics of materials, in the elastic limit scope, material under external force, the material pressurized produces strain, pressure relief, distortion can complete obiteration.
The utility model is finished the support effect by the following effects mode:
The first step: counter-rotating spanner 4, unclamp briquetting 3, according to the mutual alignment of the described two pairs of arc top boards 11 of workpiece shape adjustment, the support device is in treats duty.
Second step: spanner 4 turns clockwise, because of a screw rod 2 and an arc top board 11 that is positioned at the outside are welded as a whole, the arc top board that is expressed as this screw rod 2 and foot in Fig. 1,3,5A, 6A is welded as a whole, so briquetting 3 will produce a downward relative displacement in spanner 4 rotations, thereby form active force to arc top board 11 upper and lower surfaces, make the arc inside compression of top board, drive the support 13 be arranged on the top board both ends simultaneously and produce lateral displacements, utilize the strain of material to reach the effect of support.
The 3rd step: counter-rotating spanner 4, unclamp briquetting 3, release pressure recovers strain, finishes the support effect.
As mentioned above, by the support effect to workpiece, the welding of avoiding workpiece in the welding process to produce is shunk, thereby effectively controls the local welding distortion of top cover, the distortion runaway condition when having remedied existing locomotive header and welding such workpiece.Dimensional accuracy and surface quality are effectively guaranteed in welding process.
