Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding, in particular to a high-efficiency positioning device for welding the spout of a hardware kettle. BACKGROUND

[0002] In the field of hardware product processing, as a widely used heating appliance in daily life, the production and manufacturing process of the kettle has strict requirements on structural precision, safety and assembly stability. Among them, the welding connection of the spout and the kettle body is one of the core processes of the kettle production, and the positioning accuracy of the spout directly determines the smoothness of the kettle, the sealing performance and the overall appearance quality. If the positioning deviation is too large, it will not only cause functional problems such as water leakage and water out of skew, but also may cause the kettle body to crack due to uneven welding stress distribution, which has serious safety hazards.

[0003] At present, in the spout welding process of the hardware kettle, the mainstream positioning method in the industry is still mainly traditional manual positioning. Manual positioning relies on the experience judgment of the operator, and the spout and the kettle body are observed by the naked eye to determine the docking position, and the angle, height and radial position of the spout are manually adjusted and temporarily fixed. Due to human visual error, hand operation jitter and experience difference, the positioning accuracy is difficult to control, resulting in low welding precision and affecting the production quality and production efficiency of the kettle.

[0004] Therefore, in view of the above status, it is urgent to provide a high-efficiency positioning device for welding the spout of a hardware kettle to overcome the deficiencies in current actual applications. SUMMARY

[0016] and a motor is fixedly installed on the support frame, and the output shaft of the motor is fixedly connected with the second rotating shaft.

[0017] As a further scheme of the present application, the positioning assembly comprises:

[0018] A positioning tube is rotatably connected with the rotating plate through the adjusting assembly, and the end of the positioning tube away from the rotating plate is of an open structure;

[0019] A limiting hole for accommodating the handle on the kettle body is formed on the side wall of the positioning tube;

[0020] A support bar is fixedly installed on the rotating plate, and a plurality of guide rods are slidably installed on the support bar, and one end of the guide rod is provided with a stop block;

[0021] A translation bar is fixedly installed on the guide rod, and a spring for elastically supporting the translation bar is further sleeved on the guide rod;

[0022] and a limiting block for blocking the handle on the kettle body is fixedly installed on the translation bar.

[0023] As a further scheme of the present application, the adjusting assembly comprises:

[0024] A first rotating shaft is rotatably installed on the rotating plate, the end of the first rotating shaft is fixedly connected with the positioning tube, and a back-and-forth spring for resetting the rotated first rotating shaft is further arranged between the first rotating shaft and the rotating plate;

[0025] and a friction wheel is fixedly installed on the first rotating shaft.

[0026] As a further scheme of the present application, the kettle positioning mechanism further comprises a friction strip for driving the rotation of the friction wheel, the friction strip is fixedly connected with the support frame through the fixing frame, and the friction strip is in a circular arc structure.

[0028] As a further scheme of the present application, the auxiliary positioning assembly comprises:

[0029] A fixing plate fixedly installed at the end of the support frame, and a support plate fixedly installed at the bottom of the fixing plate;

[0032] Compared with the prior art, the present application has the following advantages:

[0033] First, the positioning accuracy is greatly improved, and the welding quality is guaranteed

[0034] Multi-dimensional cooperative positioning eliminates welding deviation: the device realizes accurate fixing of the kettle through the three-level positioning logic of "positioning assembly preliminary limiting + auxiliary positioning assembly pressing and fixing + locking air bag final locking". In the positioning assembly, the limiting hole cooperates with the limiting block to ensure that the handle of the kettle, the welding position and the center point of the rotating plate are in a straight line. The electric telescopic cylinder drives the pressing strip to press the handle, further strengthening the positioning stability. When the pressing strip moves downward, the piston plate is synchronously triggered to push the gas, so that the locking air bag at the bottom of the positioning tube is inflated to press the kettle, avoiding the displacement of the kettle during welding.

[0035] Accurate alignment of kettle body and spout: when the rotating assembly drives the rotating plate to rotate, the friction wheel cooperates with the arc-shaped friction strip to drive the positioning tube to rotate to adjust the angle of the kettle body, ensuring that the welding position of the kettle body is accurately positioned towards the spout positioning mechanism when the kettle body moves to the lowest point. In the spout positioning mechanism, the turntable drives the limiting frame to rotate, and the telescopic cylinder pushes the limiting frame to rise and fall, which can accurately press the spout to the welding position of the kettle body, completely solving the problem of difficult positioning accuracy control and large welding deviation in the prior art, and ensuring the sealing performance and structural stability of the kettle after welding.

[0036] II. Improve production efficiency and realize batch efficient operation

[0037] Multi-station synchronous operation, reduce waiting time: the positioning assembly is arranged in a circular array (preferably four groups) on the rotating plate, and the limiting frame of the spout positioning mechanism is arranged in multiple groups at equal intervals on the turntable. Workers can place the kettle body and spout on idle stations at the same time, and the rotating plate and the turntable rotate alternately to realize continuous operation of "feeding-positioning-welding-discharging", avoiding waiting gaps during single-station operation, and greatly improving the number of welds per unit time.

[0038] Automatic adjustment, reduce operation time: the motor drives the rotating plate to rotate accurately (the rotation angle is matched with the number of positioning assemblies each time, such as 90° when there are four groups), and the driving mechanism drives the turntable to rotate automatically, without the need for manual adjustment of the positions of the kettle body and spout. The cooperation of the friction wheel and the friction strip can automatically complete the angle calibration of the kettle body, reducing the time cost of manual alignment and significantly improving the overall production efficiency.

[0039] III. Reduce the labor burden of workers and lower the operation threshold

[0040] Simplify the feeding operation and do not need accurate pre-positioning: when placing the kettle body, the worker only needs to put the kettle handle into the limiting hole of the positioning tube, without the need for high-precision pre-alignment of the kettle body, reducing the operation difficulty; after welding, the rotating plate continues to rotate to separate the friction wheel and the friction strip, and the return spring drives the positioning tube to reset, making it convenient for workers to quickly take out the welded kettle body and reducing the cumbersome alignment and taking steps.

[0041] Elastic structure protection, reduce rework cost: in the positioning assembly, the spring on the guide rod elastically supports the translation bar, and the limiting block elastically contacts when pressing the handle, which can avoid damage to the handle caused by the positioning tube and the kettle body being stuck; the locking air bag uses a flexible extrusion method to fix the kettle body, preventing rigid clamping from scratching the surface of the kettle body, reducing rework caused by workpiece damage, and reducing the operation pressure and rework processing time of workers.

[0042] IV. Enhance the versatility of the device and adapt to different specifications of products

[0043] The limiting frame can be flexibly replaced, and is suitable for different spouts: the limiting frame of the spout positioning mechanism is in sliding connection with the turntable groove, and can be replaced according to the shape of different specifications of spouts to open the corresponding limiting groove, without the need to replace the whole spout positioning mechanism, thereby reducing the equipment modification cost.

[0044] The positioning pipe is suitable for multiple kettle sizes: the positioning pipe is of an open structure and is fixed by inflation and extrusion of the locking air bag, and the elastic deformation of the air bag can adapt to different diameters of the kettle, without the need to design a separate positioning clamp for different sizes of the kettle, thereby improving the adaptation ability of the device to different specifications of thermos kettles and expanding the application range.

[0045] Five, stable and reliable structure design, prolong the service life of the device

[0046] Key components are strengthened to improve durability: the inner surfaces of the friction wheel and the friction strip are covered with rubber material to increase friction while reducing component wear; the second rotating shaft of the rotating assembly and the first rotating shaft of the adjusting assembly are both in rotating installation structure, which cooperates with the rotary spring to realize resetting and reduce mechanical jamming; the compression cylinder and the guide pipe are designed to be sealed to ensure stable gas transmission, avoid air leakage leading to failure of the locking air bag, and ensure long-term stable operation of the device.

[0047] The linkage mechanism is precisely controllable and reduces the risk of failure: in the auxiliary positioning assembly, the pressing strip, the push-pull rod, the piston plate and the locking air bag form linkage, the locking air bag is inflated only when the pressing strip moves downward, and the gas only enters the locking air bag of the bottommost positioning pipe, avoiding energy waste and component wear caused by invalid inflation; the actions of each component are realized through mechanical structure linkage, reducing the probability of electronic component failure and improving the overall reliability of the device.
