Description

TECHNICAL FIELD

[0001] The utility model relates to welding machine field especially relates to a metal welding machine. BACKGROUND

[0002] Ultrasonic metal welding is a special method of connecting the same metal or dissimilar metal by using the mechanical vibration energy of ultrasonic frequency. When the metal is welded by ultrasonic, no current is supplied to the workpiece, and no high-temperature heat source is applied to the workpiece. Only mechanical energy is converted into internal energy, deformation energy and limited temperature rise under static pressure. Solid-phase welding occurs when the two base materials reach the recrystallization temperature. Therefore, it effectively overcomes the phenomena of spatter and oxidation generated during resistance welding. The ultrasonic metal welding machine can perform single-point welding, multi-point welding and short strip welding on thin wire or sheet materials of non-ferrous metals such as copper, silver, aluminum and nickel. It can be widely used in the welding of thyristor leads, fuse links, electric appliance leads, lithium battery pole pieces and tabs.

The metal welding machine in the prior art has a simple structure, and cannot adjust the stroke of the air cylinder drive end. This limits the welding work of the metal welding machine, and further causes limitations in the actual application of the welding machine. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0017] The embodiment of the present application provides a metal welding machine, and solves the technical problem that the metal welding machine in the prior art has limitations in practical application because the metal welding machine cannot adjust the stroke of the driving end of the air cylinder due to the simple structure of the metal welding machine, so that the metal welding machine is limited in welding work.

[0018] The technical solution in the embodiment of the present application is as follows to solve the above problems:

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail in combination with the drawings of the specification and specific embodiments.

The air cylinder 6 is installed at the top end of the rack 2. The driving end of the air cylinder 6 is in transmission connection with the welding device 3. The welding device 3 slides on the sliding rail 5, and the sliding rail 5 is arranged on the rack 2. The limiting mechanism 7 is installed on the rack 2, and the limiting mechanism 7 is in transmission connection with the welding device 3. The support tool 4 is arranged on the top of the base 1.

[0021] The welding device 3 comprises a pressure sensor 31, a fixing seat 32, a clamp 33 and a welding head assembly 34. The pressure sensor 31 is arranged at the driving end of the air cylinder 6. The fixing seat 32 is arranged on the pressure sensor 31, and the fixing seat 32 slides on the sliding rail 5. The clamp 33 is arranged on the fixing seat 32. The welding head assembly 34 is detachably installed on the clamp 33. The limiting mechanism 7 is in transmission connection with the fixing seat 32. The welding head assembly 34 is composed of a transmission rod, a welding head, an amplitude-changing rod, a transducer and a counterweight rod. By extending or retracting the driving end of the air cylinder 6, the welding device 3 can be driven to ascend and descend, and the fixing seat 32 can slide up and down along the sliding rail 5.

[0022] The limiting mechanism 7 comprises a rotating rod 71, a limiting seat 72, a pushing rod 73, a rack 74, a gear 75 and a support block 76. The support block 76 is rotatably connected to both ends of the rotating rod 71. The two groups of support blocks 76 are arranged on the rack 2. The limiting seat 72 is installed on the rack 2. The pushing rod 73 slides on the limiting seat 72. The rack 74 is arranged on the pushing rod 73. The gear 75 is arranged around the rotating rod 71, and the gear 75 is in meshing connection with the rack 74. The bottom end of the pushing rod 73 is connected to the fixing seat 32.

[0023] When the gear 75 rotates, the rack 74 on the push rod 73 is driven to move up and down along the limiting seat 72. Since the bottom end of the push rod 73 is connected to the fixed seat 32, when the push rod 73 moves up and down along the limiting seat 72, the fixed seat 32 is driven to slide along the slide rail 5, thereby adjusting the distance between the welding device 3 and the support tool 4, indirectly adjusting the stroke of the driving end of the air cylinder 6, and greatly improving the practicability of the metal welding machine.

[0024] The support tool 4 comprises a pressing mechanism 41, a horizontal pushing mechanism 42, a clamping block 43, and a supporting part 44. The pressing mechanism 41 is arranged on the base 1. The supporting part 44 is arranged on the pressing mechanism 41. Two groups of horizontal pushing mechanisms 42 are symmetrically arranged on the pressing mechanism 41. The clamping blocks 43 are arranged on the driving ends of the two groups of horizontal pushing mechanisms 42. The two groups of clamping blocks 43 are symmetrically arranged on the supporting part 44. The horizontal pushing mechanism 42 is preferably a pneumatic sliding block.

[0025] The base 1, the rack 2, the welding device 3, the support tool 4, the slide rail 5, the air cylinder 6, and the limiting mechanism 7 are arranged, and the pressure sensor 31 is arranged to monitor the pressure change in the welding process in real time, ensuring the stability and uniformity of the welding pressure, thereby significantly improving the welding quality. The lifting and sliding movement of the welding device 3 is driven by the air cylinder 6, and the precise control of the slide rail 5 and the limiting mechanism 7 ensures that the welding device remains stable during the welding process, avoiding welding defects caused by mechanical vibration. The limiting mechanism 7 is designed to be clever, and the meshing movement of the gear 75 and the rack 74 driven by the push rod 73 realizes the precise adjustment of the distance between the welding device 3 and the support tool 4. This not only flexibly adapts to the welding needs of workpieces of different sizes, but also effectively limits the stroke of the driving end of the air cylinder 6, avoiding mechanical damage caused by excessive extension or retraction. The symmetrical layout of the pressing mechanism 41 and the horizontal pushing mechanism 42 of the support tool 4 ensures that the workpiece is uniformly supported and positioned during the welding process, further improving the applicability and flexibility of the welding machine. The welding head assembly 34 is designed to be detachable, which facilitates quick replacement and maintenance according to different welding needs, reduces downtime, and improves production efficiency. The cooperation of the limiting mechanism 7 and the support tool 4 makes it more convenient and safe for the operator to adjust the position of the welding device, reducing the difficulty and risk of operation. The components of the metal welding machine are arranged reasonably and compactly, reducing unnecessary mechanical wear and energy loss, and prolonging the service life of the equipment.
