Description

Technical Field

[0001] The invention relates to the technical field of mechanical welding, and in particular to welding equipment for machining engineering machinery parts. Background Art

[0002] Mechanical welding is a forming method that uses heating or pressurization (or both) to create an atomic bonding force between two separated metal objects and connect them into one. According to the degree of heating and process characteristics during the welding process, welding methods can be divided into three categories: fusion welding, pressure welding and brazing. Fusion welding is to locally heat the welding point of the workpiece to a molten state to form a molten pool, which is cooled and crystallized to form a weld; pressure welding is a welding method that requires pressurization regardless of whether it is heated or not during the welding process; brazing is to use a brazing material with a melting point lower than the metal to be welded to melt, fill the joint gap, and diffuse with the metal to be welded to achieve connection. Mechanical welding has the advantages of high strength, stability and reliability, saving metal materials, and the ability to manufacture heavy and complex machine parts by combining small and large parts. Common mechanical welding methods include arc welding, submerged arc welding, argon arc welding, gas welding, laser welding, etc. Among them, laser welding has the advantages of fast welding speed, high precision and good quality, and is widely used in modern manufacturing.

[0003] Mechanical welding requires a welding fixture. The existing welding fixture can only clamp and fix the material when in use. The position of the material cannot be efficiently moved during welding. At the same time, the welding device cannot perform efficient angle adjustment, resulting in a single angle when welding parts. Efficient welding cannot be performed when facing some special-shaped contact surfaces, which reduces the stability of welding and is not conducive to the use of the machine.

[0004] Therefore, it is necessary to redesign the welding fixture to effectively prevent the problems existing in the above-mentioned background technology. Summary of the invention

[0005] The present invention provides a welding device for machining engineering machinery parts to solve the problems raised by the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution of the present invention is as follows: An embodiment of the present invention provides a welding device for processing engineering machinery accessories, comprising: a base plate, a power box fixedly connected to the top of the base plate, a rotating motor fixedly installed on the right side of the top of the base plate, a pulley fixedly connected to the output end of the rotating motor, a belt movably connected to the surface of the pulley, the top of the belt movably connected to a rotating frame through the pulley, a rotating box fixedly installed on the inner side of the rotating frame, a support frame movably connected to the surface of the rotating frame, the bottoms of the two support frames are fixedly connected to the top of the base plate, a sliding mechanism is provided inside the power box, the sliding mechanism is used to move the welding device, and an adjusting clamping mechanism is provided inside the rotating box, the adjusting clamping mechanism is used to adjust the angle and fix the position of the accessory.

[0007] Through the above technical scheme, through the stable connection between the base plate and the power box, and the ingenious cooperation between the rotating motor and the belt, the flexible movement and precise positioning of the welding device in three-dimensional space are realized. The linkage design of the rotating frame and the rotating box enables the accessories to be easily adjusted at multiple angles to meet the needs of complex welding processes. At the same time, the built-in sliding mechanism of the power box further enhances the operating convenience of the welding device and ensures the efficient progress of the welding operation. In addition, the adjustment and clamping mechanism in the rotating box can accurately fix the position of the accessories, effectively prevent displacement and deformation during welding, and ensure the stability and reliability of the welding quality.

[0008] Furthermore, the sliding mechanism includes a first motor, which is fixedly mounted at the bottom of the inner wall of the power box, and an output end of the first motor is fixedly connected to a driving synchronous wheel, a surface of the driving synchronous wheel is meshed with a synchronous belt, both ends of the synchronous belt are meshed with driven synchronous wheels, and screws are fixedly connected to the insides of the two driven synchronous wheels.

[0009] Through the above technical solution, the sliding mechanism realizes high-precision linear movement of the welding device inside the power box by integrating the first motor, the active synchronous wheel, the synchronous belt and the driven synchronous wheel. The stable drive of the first motor ensures the smoothness and controllability of the welding process. The precise meshing of the active synchronous wheel and the synchronous belt effectively transmits the driving force, while reducing the friction and wear during the movement and extending the service life of the equipment. The screw design fixed inside the two driven synchronous wheels not only enhances the stability of the structure, but also enables the sliding mechanism to accurately position the welding device, meeting the stringent requirements of the complex welding process for precision.

[0010] Furthermore, the surface of the screw rod is threadedly connected with a screw sleeve, the top of the screw sleeve is fixedly connected with a support plate, and the bottom of the support plate is fixedly connected with a mechanical welding arm.

[0011] Through the above technical scheme, the mechanical welding arm can move up and down accurately along the axial direction of the screw, so as to realize accurate welding of accessories at different heights. The threaded connection between the screw sleeve and the screw not only ensures the smoothness and reliability of the movement of the mechanical welding arm, but also enables the movement process to have a fine-tuning function, which can meet the extremely high requirements for welding position accuracy. The support plate serves as a bridge connecting the screw sleeve and the mechanical welding arm, which not only enhances the stability of the structure, but also ensures the rigidity of the mechanical welding arm during movement, avoiding welding errors caused by vibration or external force interference.

[0012] Furthermore, the adjusting clamping mechanism includes an adjusting motor, which is fixedly mounted on the bottom of the inner wall of the rotating box, a worm is fixedly connected to the output end of the rotating motor, a worm is meshed with a worm wheel on the surface of the worm, a positioning rod is fixedly connected to the inside of the worm wheel, and the end of the worm away from the adjusting motor is movably connected to a positioning plate through a bearing seat, and the bottom of the positioning plate is fixedly connected to the bottom of the inner wall of the rotating box.

[0013] Through the above technical solution, the adjusting clamping mechanism realizes precise angle adjustment and firm clamping of accessories by integrating components such as the adjusting motor, worm, worm wheel and positioning rod. The stable drive of the adjusting motor ensures the smooth rotation of the worm, and then through the precise meshing of the worm wheel and the worm, the rotational motion is converted into the rotational motion of the positioning rod to meet the needs of accessory angle adjustment.

[0014] Furthermore, the top of the positioning rod is fixedly connected to a clamping box, the outer side of the clamping box is fixedly connected to a limiting ring, the top and bottom of the two limiting rings are movably connected to balls, the number of the balls is several and evenly distributed in a ring shape, and the limiting ring is used in conjunction with the surface of the inner wall of the clamping box.

[0015] Through the above technical solution, by setting the limiting ring and the ball, it is convenient to effectively limit the clamping box, while reducing the friction between the limiting ring and the clamping box, and improving the stability of the rotation of the clamping box.

[0016] Furthermore, the surface of the inner wall of the clamping box is movably connected to an electric push rod via an axle pin, the output end of the electric push rod is movably connected to a turntable via an axle pin, the interior of the turntable is fixedly connected to a rotating column, and the top and bottom of the rotating column are movably connected to the top and bottom of the inner wall of the clamping box via a bearing seat.

[0017] Through the above technical solution, the design of the electric push rod enables the clamping box to be dynamically adjusted according to the size and shape of the accessories, thereby achieving precise clamping of the accessories. The output end of the electric push rod is movably connected to the turntable through an axle pin, and the rotating column fixed inside the turntable is movably connected to the inner wall of the clamping box through a bearing seat. This design not only enhances the stability of the structure, but also enables the turntable to rotate easily under the drive of the electric push rod, thereby driving the accessories to be fine-tuned to meet the precise angle requirements of complex welding processes. In addition, the telescopic function of the electric push rod enables the clamping box to adapt to accessories of different sizes, greatly enhancing the versatility and flexibility of the equipment.

[0018] Furthermore, a pull bar is movably connected to the top of the turntable via an axle pin, and a clamping block is movably connected to the damper via an axle pin at the top of the pull bar, and the number of the clamping blocks is several.

[0019] Through the above technical solution, the turntable is cleverly connected with the damper and the clamping block through the pull rod to construct a flexible and stable clamping system. The design of the pull rod enables the turntable to drive the clamping block to move synchronously when rotating, thereby realizing all-round clamping of the accessories. The addition of the damper effectively reduces the impact of the clamping block during movement, ensuring the smoothness and controllability of the clamping process. At the same time, the design of multiple clamping blocks not only enhances the clamping force, but also enables the equipment to adapt to accessories of different shapes and sizes, greatly improving the versatility and practicality of the equipment.

[0020] Furthermore, a slide groove for use with the clamping block is provided on the top of the clamping box.

[0021] Through the above technical solution and the setting of the slide groove, the clamping block can be easily moved efficiently.

[0022] Furthermore, one end of the forward and reverse rotating screw rod away from the driven synchronous wheel is movably connected to a positioning block via an axle pin, and the bottom of the positioning block is fixedly connected to the top of the base plate.

[0024] Furthermore, a wedge block is fixedly connected to the surface of the support frame, and a bottom of the wedge block is fixedly connected to the top of the base plate.

[0025] Through the above technical solution, by setting the wedge-shaped block, it is convenient to efficiently fix the support frame, improve the stability of the rotation of the rotating box, and facilitate the use of the user.

The present invention starts the first motor, and the first motor rotates to drive the active synchronous wheel to rotate, thereby driving the synchronous belt to rotate, and the driven synchronous wheel is driven to rotate through the synchronous belt, thereby driving the forward and reverse screws to rotate, driving the screw sleeve and the support plate to move, so as to adjust the mechanical welding arm, and at the same time start the rotating motor, the rotating motor drives the pulley to rotate, thereby driving the belt to rotate, and then driving the rotating frame to rotate along the support frame, thereby driving the rotating box to adjust the angle, and then starting the adjusting motor, the adjusting motor rotation drives the worm to rotate, thereby driving the worm wheel to rotate, and the rotation of the worm wheel drives the positioning rod to rotate, so that the clamping box rotates through the limit ring and the ball, and the horizontal angle of the accessory is adjusted, and then the electric push rod is started, and the turntable is driven to rotate by the electric push rod, thereby driving the pull rod to pull the clamping block to efficiently clamp and fix the ingredients, thereby achieving an effect of efficient fixing, thereby improving the welding efficiency.

[0027] 2. The present invention facilitates efficient positioning of the clamping box by providing a limiting ring and a ball, while reducing the friction between the limiting ring and the clamping box and improving the stability of the rotation of the clamping box.
