Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding production and processing technology, and in particular to a welding quality analysis device. Background Technology
[0002] In the welding production process, welding quality inspection is carried out throughout the entire process from product design to finished product.
[0003] A search revealed a combined welding quality analysis device, comprising a testing platform (publication number: CN108333065B). A control console is movably mounted on the top wall of the testing platform. A first adjusting rod is inserted into the top wall of the control console. A grip is mounted on the top end of the first adjusting rod, and a pressure plate is mounted on the bottom end of the first adjusting rod. Two second adjusting rods are symmetrically inserted into the two side walls of the control console, and the two second adjusting rods respectively penetrate the two side walls of the pressure plate and extend to the inner side of the pressure plate. A top block is mounted on the opposite end of each of the two second adjusting rods.
[0004] The existing technology clamps one edge of the weld by pressing down with a top block, but the weld seam is not within the clamping range. When the upsetting block upsets the weld seam, if the welding quality is poor, the two welded plates will separate. The stress release during the desoldering process, coupled with the lack of restraint on the two plates, makes it very easy for the plates to jump significantly, which poses a certain risk and has room for optimization.
[0005] Therefore, we propose a welding quality analysis device. Utility Model Content
[0006] The present invention mainly addresses the technical problem of welded parts easily detaching and jumping, which poses a hidden danger, by providing a welding quality analysis device.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a welding quality analysis device, comprising:
[0008] A base, on the top of which a push rod is mounted, and an upsetting block is fixedly mounted on the output shaft of the push rod. A testing table for placing workpieces is also fixedly mounted on the top of the base.
[0009] The limiting assembly has two sets symmetrically arranged on the inspection table for clamping workpieces. The limiting assembly includes a slider, a pressure plate, a guide rod, and an adjusting screw. Two sliders are arranged below the pressure plate. A screw is provided on the top of the inspection table to drive the two pressure plates to move towards each other. The adjusting screw is rotatably connected to the slider and threadedly connected to the pressure plate. The guide rod is fixedly connected to another slider, and the pressure plate can slide along the guide rod.
[0010] In a preferred embodiment of this utility model, two parallel sliding grooves are formed on the top of the testing platform, and two sliders under the same pressure plate are respectively slidably disposed in the two sliding grooves.
[0011] In a preferred embodiment of this utility model, the lead screw is disposed in one of the slide grooves and rotatably connected to the testing table, and the lead screw is threadedly connected to two sliders in the same slide groove.
[0012] In a preferred embodiment of this utility model, the top of the pressure plate is provided with a threaded hole and a limiting hole, the adjusting screw is threadedly connected to the threaded hole, and the guide rod is slidably disposed in the limiting hole.
[0013] In a preferred embodiment of this utility model, the limiting component further includes a roller shaft, and several pressure plates are equidistantly arranged at the bottom of the pressure plate, the pressure plates being able to abut against the workpiece.
[0014] In a preferred embodiment of this utility model, the bottom of the pressure plate is provided with several arc-shaped grooves, and the roller shaft is rotatably installed in the arc-shaped grooves, with the circumferential surface of the roller shaft protruding from the bottom surface of the pressure plate.
[0015] In a preferred embodiment of this utility model, a two-axis truss is fixedly installed on the top of the base, and the push rod is fixedly installed on the output end of the two-axis truss by a bracket.
[0016] Beneficial effects
[0017] This invention provides a welding quality analysis device. It has the following beneficial effects:
[0018] 1. This welding quality analysis device adjusts the distance between two fast pressure plates by rotating a lead screw to bring two sets of sliders closer together, adapting to the limiting of welds of different widths. It has good adaptability and a large clamping range. Rotating the adjusting screw causes the pressure plates to move vertically along the guide rod. The two pressure plates press down and limit the two ends of the weldment. During the upsetting process of the weld by the upsetting block, since the ends of the two plates are located under the same pressure plate, even if the welding effect is poor and the two plates are detached, the pressure plate can still limit the two plates, avoiding accidental damage caused by stress release and bounce of the two plates during the detachment process. The safety of the detection process is guaranteed.
[0019] 2. This welding quality analysis device, by setting several rollers at the bottom of each pressure plate, uses the downward pressure of the pressure plate to press and limit the plate on the testing table. When the upsetting block upsets the plate, the rotatable rollers do not interfere with the extension of the plate, and the two plates can extend to both sides, which can show the degree of deformation and breakage of the weldment when it is upset.

[0026] A welding quality analysis device, such as Figure 1 and Figure 2 As shown, it includes:
[0027] A base 10 is provided, a push rod 11 is mounted on the top of the base 10, an upsetting block 12 is fixedly mounted on the output shaft of the push rod 11, an inspection table 13 for placing workpieces is also fixedly mounted on the top of the base 10, and a two-axis truss is fixedly mounted on the top of the base 10. The push rod 11 is fixedly mounted on the output end of the two-axis truss through a bracket.
[0028] The position of the push rod 11 is adjusted by the two-axis truss, and the push rod 11 pushes the upsetting block 12 to rise and press the welded parts. Taking two welded plates as an example, the joint between the two plates is the weld. The upsetting block 12 is used to continuously tap the weld position, and then the upsetting block 12 is lifted to observe the weld position. The degree of bending and breakage at the weld position is used to analyze the welding quality, realizing visual inspection of the welding quality. The structure is simple and easy to implement. The upsetting block 12 is used to upset part of the welded parts next to the weld, and the weld quality is analyzed by the deformation at the weld position. The operation of the entire inspection process has low professional requirements, is simple and convenient, and the equipment cost is low, which is conducive to improving production efficiency and is worth learning from.
[0029] like Figure 1 , Figure 3 and Figure 4As shown, the limiting assembly has two sets symmetrically arranged on the inspection table 13 for clamping workpieces. The limiting assembly includes sliders 14, pressure plates 15, guide rods 16 and adjusting screws 17. Two sliders 14 are arranged below the pressure plates 15. A screw is provided on the top of the inspection table 13 to drive the two pressure plates 15 to move towards each other. The adjusting screw 17 is rotatably connected to the sliders 14 and threadedly connected to the pressure plates 15. The guide rod 16 is fixedly connected to the other slider 14. The pressure plates 15 can slide along the guide rod 16. Two parallel sliding grooves are opened on the top of the inspection table 13. Two sliders 14 below the same pressure plate 15 are slidably arranged in the two sliding grooves respectively. The screw is arranged in one of the sliding grooves and rotatably connected to the inspection table 13. The screw is threadedly connected to the two sliders 14 in the same sliding groove. A threaded hole and a limiting hole are opened on the top of the pressure plate 15. The adjusting screw 17 is threadedly connected to the threaded hole. The guide rod 16 is slidably arranged in the limiting hole.
[0030] In this scheme, the weldment is placed on the inspection table 13. By rotating the lead screw, the two sets of sliders 14 are brought closer to each other, and the distance between the two fast pressure plates 15 is adjusted to accommodate the limiting of welds of different widths. It has good adaptability and a large clamping range. Rotating the adjusting screw 17 causes the pressure plate 15 to move vertically along the guide rod 16. The two pressure plates 15 press down and limit the two ends of the weldment. During the upsetting process of the upsetting block 12, since the ends of the two plates are located under the same pressure plate 15, even if the welding effect is not good and the two plates are detached, the pressure plate 15 can still limit the two plates, avoiding the stress release and bounce of the two plates during the detachment process, which may cause accidental damage. The safety of the inspection process is guaranteed.
[0031] like Figure 5 As shown, the limiting assembly also includes a roller 18, and several pressure plates 15 are equidistantly arranged at the bottom of the pressure plate 15. The pressure plates 15 can abut against the workpiece. Several arc-shaped grooves are opened at the bottom of the pressure plate 15. The roller 18 is rotatably installed in the arc-shaped grooves, and the circumferential surface of the roller 18 protrudes from the bottom surface of the pressure plate 15.
[0032] In this scheme, considering that the welded part formed by welding two plates may deform and extend when it is upset, in order to facilitate the observation of the deformation range, several rollers 18 are set at the bottom of each pressure plate 15. The downward pressure of the pressure plate 15 on the rollers 18 makes the plate press and limit it on the inspection table 13. When the upset block 12 upsets the plate, the rotatable rollers 18 will not interfere with the extension of the plate, and the two plates can extend to both sides, which can show the degree of deformation and breakage of the welded part when it is upset.
[0033] The working principle of this utility model is as follows: the position of the push rod 11 is adjusted by the two-axis truss, and the upsetting block 12 is moved to the inspection table 13. The push rod 11 pushes the upsetting block 12 to rise and press the welded part. Taking two welded plates as an example, the joint of the two plates is the weld. The upsetting block 12 is continuously tapped on the weld position. Then the upsetting block 12 is lifted to observe the weld position. The degree of bending and breakage of the weld position is used to analyze the welding quality and realize the visual inspection of the welding quality.
[0034] Rotating the lead screw causes the two sets of sliders 14 to move closer to each other, adjusting the distance between the two fast pressure plates 15. Rotating the adjusting screw 17 causes the pressure plates 15 to move vertically along the guide rod 16. The two pressure plates 15 press down on the two ends of the weldment respectively, that is, the two pressure plates 15 press and limit the two ends of the two plates respectively. The pressure of the pressure plates 15 on the roller shaft 18 makes the plate press and limit it on the inspection table 13. When the upsetting block 12 upsets the plate, the rotatable roller shaft 18 will not interfere with the extension of the plate.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
