Description

Technical Field

[0001] The utility model relates to the technical field of welding positioning, in particular to a positioning device for high-precision mechanical processing welding. Background Art

[0002] High-precision machining is a manufacturing process that uses advanced mechanical equipment and technology to achieve extremely high precision and fineness. It involves many different processing technologies, such as CNC machining, electrochemical machining, laser machining, ultrasonic machining, etc. When welding mechanical parts, it is necessary to first position the welding parts to prevent deviation or deformation during welding, especially the docking between plate parts. It is necessary to use a positioning clamping device to fix the two plates to be welded in order to achieve high-precision welding process requirements; the existing positioning device has a single structure. Although it can fix the plates, it is necessary to manually splice the two fixed plates during welding, which is extremely inconvenient; and when one side of the plate is welded and the other side of the plate needs to be welded, it is necessary to disassemble the fixed plate, turn it over, and fix it, which will waste a lot of time, thereby affecting the welding efficiency; for example, "Utility Model CN214769981U A high-precision mechanical processing welding positioning device is provided with a bidirectional screw rod, a feed pipe, a micro valve, an oil storage bottle, and a slider. The plate to be welded is placed on the top of the fixed clamping plate and then the one-way screw rod is rotated. When the one-way screw rod is rotated, the movable clamping plate is moved, so that the plate is clamped and fixed by the movable clamping plate and the fixed clamping plate. Then, the bidirectional screw rod is rotated. When the bidirectional screw rod is rotated, the slider is moved, and the slider drives the movable block to move relative to each other, so that the plates can be spliced. At the same time, the micro valve is opened to allow the lubricating oil in the oil storage bottle to drip onto the outside of the bidirectional screw rod, thereby Increase the lubrication between the bidirectional screw and the slider; by setting the limit plate, No. 1 spring, limit column, connecting pipe, slide rail, limit hole, No. 2 spring, and buffer plate, the ball bearing can be aligned with the slide rail by pulling the rotating rod, and the limit plate will rotate the turntable through the connecting pipe when the rotating rod is rotated. When the turntable rotates to 180 degrees, the No. 1 spring will push the limit plate to make the positioning column buckle into the inner side of the limit hole, thereby fixing the rotating rod and realizing the flipping of the plate. "For the above problems, there may be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Utility Model Content

[0006] It should be noted that, in the above, after a pair of machined welded parts are clamped and fixed respectively by the sliding gas rod coupling clamping structure, the bonding motor in the base of the driving device is driven to rotate the bonding double threaded rod, so that a pair of workpiece carrying clamping tables are relatively moved along the moving slots of the clamping tables until a pair of machined welded parts are bonded and fixed. After welding on one side, the pair of machined welded parts are rotated 180 degrees and turned over by the rotation displacement auxiliary component, and then the next step of welding is carried out.

[0007] Preferably, the rotation displacement auxiliary component comprises: a pair of pressurized push-pull handles, a pair of handle connecting rods, a pair of fixed coupling grooves, a pair of alignment coupling keys, and a pair of auxiliary pressurized springs;

At this time, the pair of pressure push-pull handles are rotated to make the fixed pair of machined welded parts rotate and turn over. After rotating 180 degrees, the pair of pressure push-pull handles are released, and the pair of auxiliary pressure springs will rebound and make the pair of alignment coupling keys and the pair of retaining coupling grooves re-aligned. After coupling, a pair of machined welded parts are turned over and locked as a whole before welding on the other side.

While moving, a pair of auxiliary pressure springs are compressed, and then a pair of alignment coupling keys are separated from a pair of retention coupling grooves. After rotating 180° and releasing the pair of pressure push-pull handles, the alignment coupling keys are re-coupled with the corresponding retention coupling grooves to complete the fixation again.
