Description

Technical Field

[0001] This utility model relates to the field of projection welding machine technology, and in particular to a digital medium-frequency bracket projection welding machine. Background Technology

[0002] A medium-frequency bracket projection welding machine is a type of welding equipment that uses medium-frequency technology for welding, compared to traditional power-frequency welding machines.

[0003] Its higher frequency allows for a larger welding current. Furthermore, since the waveform of the intermediate frequency power supply is closer to a sine wave, it can effectively reduce interference with the power grid and improve welding stability and reliability.

[0004] A pneumatic projection welding machine is disclosed in Chinese Patent CN202021158142.8. This pneumatic projection welding machine facilitates better movement and maintenance of the machine through the cooperation between the moving wheels and the protective plate, thus solving the problem of spending a lot of time moving or maintaining the projection welding machine and improving its mobility. However, the welding rod of this pneumatic projection welding machine has a fixed shape, which makes it inconvenient to replace the welding rod. Furthermore, the shape of the projection point of the workpiece is different, and the deviation between the shape of the welding rod and the projection point of the workpiece during welding affects the welding effect. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a digital medium-frequency bracket projection welding machine, which effectively solves the deficiencies of the prior art.

[0006] The objective of this utility model is achieved through the following technical solution: A digital intermediate frequency bracket projection welding machine includes a digital intermediate frequency bracket projection welding machine body. A support platform is fixedly connected to the bottom of the front side of the digital intermediate frequency bracket projection welding machine body. A projection welding platform is provided on the top of the support platform. A lower electrode head is fixedly connected to the top of the projection welding platform. A support plate is fixedly connected to the top of the front side of the digital intermediate frequency bracket projection welding machine body. A cylinder is fixedly connected to the middle of the support plate. A motor is fixedly connected to the bottom of the output end of the cylinder. A turntable is fixedly connected to the output end of the motor. A plurality of upper electrode heads are fixedly connected to the bottom of the turntable.

[0007] Optionally, a projection welding workpiece is placed on the top of the lower electrode head, and two sets of upper electrode heads are provided at the bottom of the turntable. The two sets of upper electrode heads are located on both sides of the turntable, and the position of the upper electrode head on one side corresponds to the position of the lower electrode head below.

[0008] Optionally, the motor is a servo motor, and the angle of a single rotation of the motor output end is the included angle between two adjacent upper electrode heads, and the shapes of the upper electrode heads are different.

[0009] The above technical solution involves setting multiple upper electrode heads of different shapes on a turntable. When processing projection welding workpieces of different shapes, the motor can be started to rotate the turntable, and the upper electrode head aligned with the lower electrode head can be switched. The upper electrode head that matches the projection welding workpiece is rotated and aligned for projection welding. This allows the projection welding machine to quickly change upper electrode heads of different shapes according to the specifications of the projection welding workpiece, ensuring that the projection welding workpiece and the upper electrode head are fully compatible. The switching efficiency is extremely high, thus improving the projection welding efficiency.

[0010] Optionally, the extension and retraction stroke of the cylinder is adapted to the distance between the lower electrode head and the upper electrode head, and the lower electrode head contacts the upper electrode head when the cylinder outputs to the bottom.

[0011] The above technical solution involves installing a cylinder above the upper electrode head, which enables the upper electrode head and its associated structure to be raised and lowered, thereby completing the projection welding process on the workpiece.

[0012] Optionally, mounting plates are fixedly connected to both sides of the projection welding station, and the projection welding station is fixedly connected to the support platform through mounting plates and bolts.

[0013] The above technical solution allows for easy disassembly and replacement of the projection welding station by installing mounting plates on both sides. This facilitates the selection of a suitable projection welding station based on the specifications of the workpiece and also makes it convenient to disassemble and clean the projection welding station when needed.

[0014] Optionally, a first wire is fixedly connected to one side of the support platform. One end of the first wire is electrically connected to the main body of the digital intermediate frequency bracket projection welding machine, and the other end of the first wire is electrically connected to the lower electrode head.

[0015] Optionally, a second wire is fixedly connected to one side of the support plate. One end of the second wire is electrically connected to the main body of the digital intermediate frequency bracket projection welding machine, and the other end of the second wire is electrically connected to both upper electrode heads. The length of the second wire is greater than the sum of the cylinder's extension stroke and half the circumference of the turntable.

[0016] The above technical solution is adopted: by setting the first wire and the second wire, the two electrode heads are electrically connected to the projection welding machine respectively, and the length of the second wire is limited so that the electrical connection can be maintained even when the cylinder is fully extended and the turntable rotates 180 degrees.

[0017] This utility model has the following advantages:

This digital medium-frequency bracket projection welding machine, by setting multiple upper electrode heads of different shapes on the turntable, can start the motor to rotate the turntable when processing projection welding workpieces of different shapes, and switch the upper electrode head that is aligned with the lower electrode head. The upper electrode head that is compatible with the projection welding workpiece is rotated and aligned for projection welding. This allows the projection welding machine to quickly change the upper electrode head of different shapes according to the different specifications of the projection welding workpiece, so that the projection welding workpiece and the upper electrode head can be fully adapted, and the switching efficiency is extremely high, thereby improving the projection welding efficiency.

[0019] 2. This digital medium-frequency bracket projection welding machine uses a cylinder installed above the upper electrode head to drive the upper electrode head and its associated structure to lift and lower, thus completing the projection welding process on the workpiece. The projection welding table is installed on both sides, making it easy to disassemble and replace. It is convenient to set a projection welding table that matches the specifications of the projection welding workpiece, and it is also convenient to disassemble the projection welding table for cleaning when needed.

[0020] 3. This digital intermediate frequency bracket projection welding machine, by setting the first wire and the second wire, the two electrode heads are electrically connected to the projection welding machine respectively. By limiting the length of the second wire, the electrical connection can be maintained even under the extreme condition that the cylinder is fully extended and the turntable rotates 180 degrees.

[0029] Example 2: Motor 7 is a servo motor. The angle of a single rotation of the output end of motor 7 is the included angle between two adjacent upper electrode heads 9. The shapes of the upper electrode heads 9 are different. By setting multiple upper electrode heads 9 of different shapes on the turntable 8, when processing projection welding workpieces 10 of different shapes, motor 7 can be started to rotate the turntable 8 to switch the upper electrode head 9 aligned with the lower electrode head 4. The upper electrode head 9 that is compatible with the projection welding workpiece 10 is rotated and aligned for projection welding.

[0030] Example 3: The extension stroke of cylinder 6 is adapted to the distance between the lower electrode head 4 and the upper electrode head 9. When cylinder 6 is output to the bottom, the lower electrode head 4 contacts the upper electrode head 9.
