Description

Technical Field

[0001] The invention relates to the technical field of electric welding rods, and in particular to an automatic loading welding gun with an auxiliary supporting device and a use method thereof. Background Art

[0002] Arc welding is the most widely used welding method in industrial production. The metal to be welded is used as one electrode and the welding rod is used as the other electrode. An arc is generated when the two electrodes are close to each other. The heat generated by the arc discharge (commonly known as arc combustion) is used to melt the welding rod and the workpiece into each other and form a weld after condensation, thereby obtaining a welding process with a firm joint. When welding rods need to be replaced during traditional arc welding, manual replacement is cumbersome. When working at high altitude or in a narrow space, it is also necessary to carry an additional welding rod bag, which is a heavy burden on the staff. At the same time, traditional welding rod clamps have no support device and can only rely on manual control for stability when welding partial structures.

[0003] The invention with application number 202010760806.6 provides an automatic loading and feeding welding rod clamping device, comprising a casing, a first button, a second button and a third button are provided on the left end wall of the lower side of the casing, a moving chamber is provided in the casing, a accommodating chamber with a lower end opening connected to the moving chamber is provided in the upper end wall of the moving chamber, a driving chamber is provided in the casing, an opening chamber is provided in the front end wall of the accommodating chamber, a unloading plate is provided in the accommodating chamber, and the unloading plate can press the welding rod downward, a driving motor is fixedly connected to the lower end wall of the driving chamber, and the driving motor provides power, a rotating sleeve is provided in the moving chamber, a feeding chamber with a left end opening connected to the outside world is provided in the rotating sleeve, and a unloading chamber connected to the feeding chamber is provided at the lower end of the rotating sleeve, which can automatically load welding rods, but still has no supporting components, and the structure is relatively complicated. When the welding rod feeding component is stuck, the worker cannot remove it immediately and needs to be further disassembled before it can continue to be used. Summary of the invention

[0004] An automatic loading welding gun with an auxiliary support device comprises a power supply and a shell, wherein a fixed seat, a storage chamber and a feeding component are arranged inside the shell, a feeding port and a discharging port are respectively provided at two ends of the storage chamber, and the discharging port is arranged in a trumpet shape to prevent the welding rod from tilting up and being unable to correctly align with the discharging port during feeding, resulting in material jamming, and the feeding component is located at the top of the storage chamber, and the feeding component comprises a loading motor and a paddle, and the paddle divides the storage chamber into a left storage chamber and a right storage chamber, and the lower end of the paddle extends vertically into the storage chamber, and a narrow groove is arranged on the surface of the paddle, and the loading spring is matched with a loading spring fixing ring, and the loading spring fixing ring fixes one end of the loading spring on the fixed seat to ensure that the spring does not deviate, and also comprises a fixed shaft A and a loading spring, the paddle rotates around the fixed shaft A, and the loading spring is connected to the fixed seat A fixed seat and a paddle, a bracket is connected to the bottom of the feeding motor, and a crank A is matched with the output shaft of the feeding motor. One end of the crank A rotates around the output shaft of the feeding motor, and the other end of the crank A is connected to one end of the crank B, and the other end of the crank B is equipped with a gear C. The gear C and the reciprocating slider are fixedly connected, and a connecting rod is installed on the top of the reciprocating slider. A gear D is installed on the side of the connecting rod close to the feeding motor, and the gear D rotates around the connecting rod. The end of the connecting rod away from the feeding motor is movably connected to a movable block, and the reciprocating slider is matched with a slide rail. The feeding motor, crank A, crank B, gear C, reciprocating slider and the slide rail cooperate to form a crank reciprocating mechanism. The installation direction of the slide rail is consistent with the discharging direction. A push rod is installed on the movable block, and one end of the push rod is connected through the movable block, and the other end of the push rod is movably connected to the upper end of the paddle.

[0005] It also includes a stuck and disengaged component, the stuck and disengaged component includes a movable paddle, the movable paddle is located at the bottom of the storage cavity, the fixed seat is fixed inside the shell and the outer surface of the storage cavity, and the movable paddle is matched with a movable paddle motor;

[0006] The feeding motor, the paddle feeding spring, the fixing seat and the push rod are combined into a feeding component to realize automatic feeding. Multiple feeding components can be installed on the device. The present invention has two feeding components, and the two feeding components are synchronously fed by a connecting rod. The arrangement of the two feeding components can also prevent the welding rod from tilting and being unable to align with the discharge port due to the single feeding component during the discharging process, thereby avoiding the problem of abnormal discharging. In the process of the welding rod moving to the bottom gap, it is possible that two welding rods fall into the gap at the same time and finally get stuck above the gap, resulting in the paddle being unable to reset and the device being unable to discharge materials normally. The stuck and disengaged components provided by the present invention can effectively handle the problem. After the jamming occurs, the feeding button is long pressed to start the disengagement of the stuck components, and the feeding motor repeats the feeding process. At the same time, the movable paddle motor is started to control the movable paddle to move up and down, thereby breaking the force balance between the stuck welding rods, ensuring that only one welding rod is left in the gap at the bottom of the storage chamber, and at the same time, the paddle is reset to load and send out the welding rod.

[0007] The loading component is set on the top of the storage chamber to ensure that the welding rod can enter the discharge port only when the loading component is started. At the same time, it is ensured that when the previous welding rod has not completely left the storage chamber, the other welding rod will not be loaded due to the start of the loading component, thereby avoiding welding rod jamming; further, the paddle separates the storage chamber into a left storage chamber and a right storage chamber, ensuring that the welding rods will not cross during the placement process, resulting in subsequent loading jams, making it convenient for staff to store welding rods.

[0008] Furthermore, it also includes an energized component, a sleeve and a sensor, wherein the energized component is installed inside the sleeve, and the sensor monitors the power-on and power-off conditions and the elastic force of the spring A. The energized component includes a ball, a spring A, and an electromagnet A. The spring A movably connects the ball and the electromagnet A. The electromagnet A, spring A, and the ball are evenly distributed inside the sleeve along the circumferential direction of the discharge port. A contact is provided at the connection between the shell of the electromagnet A and the sleeve, the ball is electrically connected to the contact, and the contact is matched with a brush, which matches the contact one by one, and the brush position On the inner surface of the sleeve, the brush is connected to an external power supply, and a rack is provided on the outer surface of the sleeve, and the rack is matched with a sleeve gear, and the sleeve gear is matched with a matching motor, and the motor of the sleeve gear is electrically connected to the power-on button; an insurance measure is added, and the power-on button is pressed, the sleeve gear starts, drives the rack to move, and the rack moves the sleeve to rotate, and the brush on the inner surface of the sleeve contacts the contact to energize, and at this time, the current is transmitted to the contact through the brush, and then transmitted from the contact to the ball, and the electromagnet A is closed, and the ball directly contacts the welding core under the action of the spring A, so as to achieve the effect of energizing;

[0009] Release the power button, the sleeve gear rotates in the opposite direction of the initial rotation direction, the driving rack drives the sleeve back to the initial position, the brush and the contact are disengaged and no longer energized, and at the same time, the electromagnet A starts to attract the ball to move toward the electromagnet and disengage from the welding core, avoiding the situation where traditional welding is always energized, making it safer to use.

[0010] Furthermore, it also includes a welding rod transport component, which includes a motor, an electromagnet B, a friction wheel B, and a spring B. A slider is installed on the friction wheel B, and the slider is equipped with a slide groove. The slider is a magnet. The spring B connects the slider and the electromagnet B. The motor shaft is equipped with a gear B, and the gear B is equipped with a gear A. The gear A is equipped with a friction wheel A. A three-way connecting rod is installed on the axle of the gear A, gear B, and friction wheel A. The three-way connecting rod is movably connected to the motor shaft, and the axle of the friction wheel A is equipped with a slide groove C, and the axle of the gear A is equipped with a slide groove B. The transport component transports the welding rod to the designated work position The device is arranged to ensure that the welding core of the welding rod can correctly contact the ball. The motor is electrically connected to the sensor in the energized component. By monitoring the elastic force of the spring A in the energized component, since most of the welding rod is wrapped with a coating, the diameter of the welding rod is larger than the exposed welding core. When the welding rod moves inside the device, the friction wheel A and the friction wheel B control the advancement of the welding rod. When the welding rod passes through the energized component, the spring A contracts. When the welding core passes by, the elastic force changes, the sensor sends a signal, the friction wheel stops rotating, and the welding rod is fixed in the specified position. Compared with traditional arc welding, there is no need to repeatedly install the welding rod, which avoids the situation of loose clamping and clamping in the wrong position, thereby improving work efficiency.

[0011] Furthermore, it also includes a supporting component, which includes a ring, a foot seat, and a movable connecting block. The ring is installed at one end of the shell near the discharge port, a bearing is arranged between the ring and the shell, and a fixing hole is arranged on the outer surface of the ring, and the fixing hole is matched with a spherical joint.

[0013] The support components can better assist the workers in their work, avoiding the traditional arc welding workers relying on manpower support for a long time, reducing the workers' workload. At the same time, the welding gun can be freely slid on the track to move flexibly along the welded part, ensuring the continuity of welding and improving work efficiency.

[0014] Furthermore, a bottom sensor is installed at the bottom of the storage chamber. When there is no welding rod in the bottom gap and the paddle is reset normally, the bottom sensor controls the indicator light to send a normal signal. When there is no welding rod in the bottom gap and the paddle is not reset normally, the bottom sensor controls the indicator light to send a stuck signal.

[0018] Furthermore, a V-shaped groove is provided on the surface of the pick; the narrow groove helps the pick to better hold the main welding rod, thereby preventing the pick and the welding rod from slipping and affecting the discharge of the material.

[0019] Furthermore, the portion of the rear cover extending into the storage cavity is a sectioned cylinder, which limits the movement of the welding rod in the storage cavity, avoiding collisions with each other that may cause the rod to get stuck, the coating to rupture, and other problems.

[0020] Furthermore, an indicator light is installed on the outer shell to facilitate the staff to judge the working status of the equipment.

[0021] A method of use comprises the following steps:

[0022] S1. Loading: Open the rear cover, put an appropriate amount of welding rods into the storage cavity in the correct direction, and rotate the rear cover of the tube wall; the welding rods are accumulated in the lower part of the cavity under the restriction of the rear cover and the action of gravity. At the same time, due to the obstruction of the paddle, the welding rods cannot freely enter the discharge port.

[0023] S2. Feeding: After the power is turned on, the loading button is pressed, the loading motor starts, and crank A is driven to rotate around the driving shaft of the loading motor. The rotation of crank A drives crank B to rotate, and crank B rotates around the connecting shaft between crank A and crank B, driving gear C on the other end of crank B to rotate. Gear C and crank B are fixed as one. The rotation of gear C will drive crank B to rotate around the central axis of gear C, and at the same time push the reciprocating block to move along the slide rail. When the reciprocating block moves along the slide rail, it drives the connecting rod at the top of the reciprocating block to move along the slide rail. When the connecting rod moves along the slide rail, it pushes the push rod to move along the slide groove A. The push rod moves along the slide groove A, pushing the paddle to rotate around the fixed axis A and stretching the loading spring at the same time. The gap between the paddle and the bottom of the storage chamber becomes larger. At the same time, since the upper half of the cross-section of the storage chamber is arc-shaped and the lower half is triangular, the lower end can only accommodate one welding rod. After the paddle is removed, the welding rod The welding rod fills the gap under the action of gravity. After the push rod reaches the terminal along the slide groove A, the feeding motor is turned off, and the paddle and the push rod quickly return to the initial position under the elastic force of the feeding spring. During the recovery process of the paddle, the V-groove at the lower end clamps the welding rod filling the gap, and under the elastic force of the discharging spring, the welding rod is pushed toward the discharging port, and the welding rod is sent to the transportation component; during the recovery process of the feeding spring, the elastic force is quickly released, a part of it is used as the power for the welding rod to leave, and the other part pulls the paddle to return to its original position. During the process of the paddle returning to its original position, the push rod pushes the movable block to move along the slide groove A, driving the connecting rod to move, and the connecting rod is movably connected to the movable block, and the movable block can rotate around the connecting rod. During the resetting process, the rotation of the connecting rod drives the gear D at the other end to rotate, the rotation of gear D drives the gear C to rotate, and the rotation of gear C drives the crank B to rotate, pushing the reciprocating movable block along the slide groove back to its initial position.

[0024] S3, conveying: the welding rod is sent out from the discharge port, the front end of the welding rod contacts with the friction wheel A and the friction wheel B, the motor starts, the driving gear B rotates to drive the gear A to rotate, the gear A drives the friction wheel A to rotate, the surfaces of the friction wheels A and B contact with the welding rod, and the welding rod is driven to move toward the working port under the action of friction. When the welding rod core contacts the ball, the motor is turned off, and the welding rod transportation is completed; the friction wheels A and B also play a clamping role, clamping the welding rod under the joint action of the elastic force of the spring and the friction force, so that the welding rod will not fall off in the working state;

[0025] S4, adjustment: according to the use scenario, choose to install a suitable number of movable connection blocks and corresponding foot seats on the collar, install the track at the corresponding position of the welding part according to the need, rotate the ball joints on the movable connection blocks and the foot seats, make the foot seat slider contact the corresponding track or directly contact the support, so that the foot seat slider can slide freely along the track, and then adjust the ball joint at the connection between the collar and the movable connection block, make the welding gun rotate around the ball joint, adjust the angle between the welding rod to be welded, and complete the adjustment;

[0026] S5, power on welding: Press the power on button, the sleeve gear starts, the sleeve gear starts. The drive rack moves, the rack moves the sleeve to rotate, the brush on the inner surface of the sleeve contacts the contact and energizes, at this time the current is transmitted to the contact through the brush, and then from the contact to the ball, the ball directly contacts the welding core, achieving the effect of power on; release the power on button, the sleeve gear rotates in the opposite direction of the initial rotation direction, the drive rack drives the sleeve back to the initial position, the brush and the contact are out of contact and no longer energized;

[0027] S6, start welding: start welding work;

[0028] S7. Replace the welding rod: After the welding rod is used, long press the loading button, the electromagnet B starts, attracts the slider along the slide groove to contract the spring B, and the friction wheel B releases the welding rod. At the same time, the motor reverses to drive the three-way connecting rod to move around the motor shaft, so that the gear B and the axle of the friction wheel A move along the slide groove B and the slide groove C, release the welding rod, place the welding gun diagonally downward, and the remaining welding rods will detach from the welding gun under the action of gravity. After confirming that the remaining welding rods are detached from the welding gun, press the loading button to reload.

[0030] The movable paddle is equipped with a movable paddle motor, a feeding motor, a paddle feeding spring, a fixed seat, and a push rod to form a feeding component to realize automatic feeding. The staff does not need to carry an additional container for storing the welding rod, which reduces the burden on the staff. At the same time, it can also prevent the welding rod from tilting and failing to align with the discharge port due to a single feeding component during the discharging process, thereby avoiding the problem of normal discharging. Furthermore, a stuck disengagement component is also installed to further improve work efficiency.

[0031] Through the coordination of the transport components and the energized components, there is no need to repeatedly install the welding rod, which avoids the situation of loose clamping and wrong clamping, and improves work efficiency.
