Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary tools for welding, and particularly relates to a submerged arc welding wire consumption measuring jig and method. Background Art

[0002] Submerged arc welding is widely used in butt welding (single-wire / double-wire submerged arc welding) and butt joint welding (FAB welding) during shipbuilding. Before installing the welding wire, the welding wire is first tied with a plastic binding tape, and the binding tape is removed after installation. To detect the consumption of the welding wire, it can only be obtained by removing the welding wire from the welding machine and then estimating the consumption by weighing. Not only is the weighing estimation error large, but also, after the welding wire is removed and reinstalled, the welding wire is prone to getting disordered, which is very unfavorable for disassembly, assembly and continued use. Summary of the Invention

[0003] The purpose of the present invention is to provide a submerged arc welding wire consumption measuring jig and method, which can quickly obtain the consumption of the welding wire and reduce errors at the same time.

[0004] In order to achieve the above invention purpose, the following technical solutions are adopted for the submerged arc welding wire consumption measuring jig and method of the present invention:

[0005] A submerged arc welding wire consumption measuring jig includes a base provided on a submerged arc welding machine. The base is provided with an elastic support. The lower end of the elastic support is installed on the base, and the upper end of the elastic support is provided with a cam disk. A main shaft is inserted through the center of the cam disk, and the cam disk can rotate around the main shaft. The main shaft is connected to the elastic support. The cam disk includes a disk-shaped base body and a convex ring provided on one side of the base body. The base body and the convex ring are coaxial, and the outer diameter of the base body is larger than the outer diameter of the convex ring. The elastic support is used to elastically drive the convex ring to be in frictional contact with the welding wire. Magnets are provided on the other side of the base body, and a plurality of magnets are evenly distributed along the circumferential direction of the base body. The main shaft is provided with a fixed frame, and a magnetic induction counter is installed on the fixed frame. The magnetic induction counter is arranged opposite to the side of the base body where the magnets are installed. A magnetic induction probe is provided on the magnetic induction counter. The cam disk rotates to sequentially approach the magnetic induction probe with the magnets for detection. The base is provided with an electronic display, and the electronic display is connected to the magnetic induction counter.

[0006] Preferably, the elastic support is a double torsion spring. The double torsion spring includes two spiral segments, a connecting body, and two torsion arms. The connecting body is located between the two spiral segments and is used to connect the two spiral segments. One end of the spiral segment is connected to the connecting body, and the other end of the spiral segment extends out to form a torsion arm. Both torsion arms are connected to the main shaft. One torsion arm is fixed to the main shaft on one side of the base body, and the other torsion arm is fixed to the main shaft on the other side of the base body. The connecting body is installed on the base through a fastener assembly. The fixing assembly includes a fixing plate arranged above the base. The connecting body is arranged between the base and the fixing plate, and the fixing plate and the base are locked tightly through fasteners. Due to the elasticity of the double torsion spring, the convex ring is in frictional contact with the welding wire. Therefore, the movement of the welding wire drives the convex ring to rotate. Moreover, the double torsion spring is easy to install, and it can be fixed by locking the fixing plate on the base through fasteners.

[0007] Preferably, ten magnets are provided, and digital markings are arranged near the base body for each magnet. The digital markings are continuously marked from 1 to 10 along the circumferential direction of the base body.

[0008] Preferably, the circumference of the convex ring is 10 cm.

[0009] Preferably, the base is a magnetic adsorption type base or a fixture type base. The base being a magnetic adsorption type base or a fixture type base facilitates disassembly and assembly.

[0010] Preferably, the magnetic adsorption type base is a magnetic base, and the magnetic base is fixed on the steel plate of the submerged arc welding machine by magnetic adsorption.

[0011] Preferably, the fixture type base is arranged in a C-shaped structure. One side end of the C-shaped structure is in contact with one side surface of the submerged arc welding machine, and the other side end of the C-shaped structure is provided with a fixing bolt, and the fixing bolt is in pressure contact with the other side surface of the submerged arc welding machine.

[0012] A measuring method based on a measuring fixture for submerged arc welding wire consumption includes the following steps:

[0013] (1) Install the base on the submerged arc welding machine, and the convex ring is in frictional contact with the welding wire;

[0014] (2) When the submerged arc welding machine feeds the wire, the movement of the welding wire drives the convex ring to rotate, and the convex ring rotates and drives the base body to rotate;

[0015] (3) The rotation of the base body drives the magnets to approach the magnetic induction probe in sequence. Each time the magnetic induction probe senses the magnetic force of the magnet, the magnetic induction counter counts once and is displayed on the electronic display; when the number of times counted by the magnetic induction counter is n, the number displayed on the electronic display is n;

[0016] (4) Obtain the wire consumption according to the number displayed on the electronic display. The number displayed on the electronic display is n, and the wire consumption is n cm.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention is convenient for measurement: it can directly measure the used length of the welding wire along with the start and stop of welding, avoiding the workload of loading and unloading the welding wire, and it is very convenient to obtain the consumption of the welding wire.

[0019] 2. The present invention is ingeniously designed: by designing the perimeter of the convex ring to be 10 cm and evenly distributing ten magnets on the base body, it is convenient to calculate the consumption of the welding wire; specifically, every time the magnetic induction probe senses a magnet, the magnetic induction counter counts once, and the consumption of the welding wire is 1 cm; at the same time, through this design, the present invention clarifies that the measurement error ≤ 1 cm.
