Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding device for a cooling type oil spray nozzle. Background Art

[0002] The fuel injection nozzle of a car is a simple electromagnetic valve. When the electromagnetic coil is energized, suction is generated, the needle valve is sucked up, the spray hole is opened, and the fuel is sprayed out at high speed through the annular gap between the needle at the head of the needle valve and the spray hole, forming a mist, which is conducive to full combustion;

[0003] During the manufacturing process of automobile fuel injectors, it is often necessary to weld the components. However, the positioning device currently used in welding the fuel injectors cannot be rotated and adjusted after the fuel injectors are fixed. Therefore, when welding different positions of the fuel injectors, the fuel injectors need to be repositioned. Therefore, we propose a welding device for cooling type fuel injectors to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that it is difficult to rotate and adjust the fuel injection nozzle after the fuel injection nozzle is clamped and positioned, and proposes a welding device for a cooling fuel injection nozzle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The welding device also comprises:

[0007] A plurality of clamping mechanisms are installed at equal intervals on the top of the support platform, and the plurality of clamping mechanisms cooperate to clamp and position the fuel injector, and the bottom of the clamping mechanism extends to the bottom of the support platform;

[0008] A transmission mechanism, which is installed at the bottom of the support platform and is respectively connected to the plurality of clamping mechanisms, and is used to drive the plurality of clamping mechanisms to move;

[0009] The power mechanism is installed on the top of the workbench and is connected to the supporting shaft.

[0010] In one possible design, the clamping mechanism includes a screw rod that passes through the support platform and is rotatably connected to the support platform, a nut is threadedly connected to the screw rod, a connecting rod is rotatably connected to the nut, one end of the connecting rod is rotatably connected to a movable plate, the movable plate is slidably connected to the top of the support platform, a clamping plate is fixedly installed on the top of the movable plate, and the bottom end of the screw rod is connected to the transmission mechanism.

[0011] In a possible design, the transmission mechanism includes a driving gear fixedly mounted on the bottom end of the screw rod, and a gear ring is rotatably connected to the bottom of the support platform, and the gear ring is meshed with a plurality of driving gears.

[0012] In a possible design, an arc-shaped positioning plate is fixedly installed on one side of the support platform, and a plurality of slots are provided at equal intervals on the arc-shaped positioning plate. A support plate is fixedly installed on one side of the gear ring, and a pressure rod is slidably connected through the support plate. A card plate is fixedly installed on the pressure rod, and the card plate is movably engaged with the plurality of slots.

[0013] In a possible design, a tension spring located below the support plate is sleeved on the pressure rod, and the top and bottom ends of the tension spring are fixedly connected to the bottom of the support plate and the bottom end of the pressure rod respectively.

[0014] In a possible design, the power mechanism includes a driving motor fixedly mounted on the top of the workbench, an active bevel gear is fixedly mounted on the output shaft of the driving motor, a driven bevel gear is fixedly sleeved on the support shaft, and the active bevel gear is meshed with the driven bevel gear.

[0015] In the present application, the fuel injector to be welded is firstly arranged between a plurality of clamping plates, and then the pressure rod can be pressed downward to move the clamping plate out of the clamping slot, and then the pressure rod can be pushed to drive the gear ring to rotate, and at this time, under the meshing transmission action with a plurality of driving gears, a plurality of screw rods can be driven to rotate, and when the screw rods rotate, the nuts can be driven to move downward, and at this time, under the push of the connecting rod, the movable plate can be driven to move, so that the clamping plate can be brought closer to the fuel injector, and then the fuel injector can be clamped and positioned conveniently, and then the pressure rod can be released, and the tension spring in a stressed state can provide an upward pulling force for the pressure rod. Force can be used to prevent the problem of separation when the clamping plate and the clamping slot are clamped together, so that the multiple clamping plates can be stably limited so that the fuel injector can be stably clamped.
