Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a height-adjustable welding device and a dual-station welding equipment. Background Technology

[0002] Induction welding is a welding technique that uses the principle of electromagnetic induction. When a high-frequency current passes through an induction coil, a changing magnetic field is generated. This magnetic field acts on conductive or magnetic materials, causing eddy currents (induced currents) to be generated inside them. Due to the presence of resistance, these eddy currents generate heat, thereby heating the metal material to its melting point, thus achieving welding and fixing.

[0003] In existing technologies, most induction welding involves fixing the workpiece to be processed on a fixture at the workstation. The welding machine of this type of welding equipment cannot be raised or lowered and can only weld one point at a time. When multiple points need to be welded, the position of the workpiece on the fixture is adjusted to weld different places. Automatic raising and lowering adjustment cannot be achieved, and multi-segment welding cannot be performed, resulting in low efficiency. Utility Model Content

[0004] This invention overcomes the problems of welding machines being unable to move vertically or automatically, and being unable to perform multi-stage welding, resulting in low efficiency. It provides a height-adjustable welding device and a dual-station welding equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable welding device includes a frame and a welding machine disposed within the frame. The welding machine includes a welding body with a laterally extending welding section on its side. The welding machine is connected to a lifting mechanism for moving the welding machine up and down.

[0007] As described above, the adjustable welding device includes a lifting mechanism comprising a lifting screw, one end of which is connected to a drive mechanism, and the other end of which is fitted with a nut seat. The drive mechanism is used to rotate the lifting screw, thereby driving the nut seat to move along the axial direction of the lifting screw. The nut seat is fixed to the welding machine and is used to drive the welding machine to perform lifting movements.

[0008] As described above, the adjustable welding device further includes a support assembly for mounting the welding machine body, and the lifting mechanism further includes a guide rail arranged along the length direction of the lifting screw. The guide rail is provided with a slider that can move axially along the guide rail, and the slider is fixed in cooperation with the support assembly.

[0009] The height-adjustable welding device described above includes a detection mechanism, which includes a temperature probe and a PID controller electrically connected to the temperature probe. The temperature probe is used to detect the temperature of the workpiece to be processed.

[0010] In the height-adjustable welding device described above, the temperature sensing probe is mounted on the frame and located directly above the welding section.

[0011] As described above, the adjustable welding device has a mounting hole on the welding body, and the welding part includes a welding induction coil. The welding induction coil extends to have a plug-in post, which is fixed in place with the mounting hole.

[0012] As described above, the height-adjustable welding device has electrodes on its welding body, and the insertion post is connected to the electrodes on the welding body.

[0013] As described above, the height-adjustable welding device has an air blowing mechanism fixedly installed on the frame. The air blowing mechanism includes an air blowing pipe and a helium blowing pipe, both of which are bamboo-joint tubes.

[0014] As described above, the adjustable welding device includes a frame with a work platform. The work platform is provided with a clamping mechanism for fixing the workpiece to be processed. The clamping mechanism includes a mounting base that can move along the plane of the work platform. The mounting base is provided with a quick-release fixing column for fixing the workpiece to be processed.

[0015] A dual-station welding device, including the aforementioned adjustable welding apparatus.

[0016] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0017] 1. With the structure of this utility model, since the welding machine and the lifting mechanism are fixed, the welding part is provided on the side of the welding machine body. The lifting mechanism drives the welding machine to move up and down, thereby making the welding part move up and down, thus realizing automatic lifting and adjustment, performing multi-segment welding, and greatly improving efficiency.

[0018] 2. The detection mechanism is equipped with a temperature probe, which is used to detect the temperature of the workpiece to be processed. The temperature is then controlled by a PID controller. When the temperature is too high, the PID controller controls the equipment to cut off the power and controls the air blowing pipe to blow air to cool it down. The PID controller can also accurately control the power of the heating element according to the set temperature curve to ensure the consistency of product quality.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Figure 1 As shown, this embodiment discloses a dual-station welding equipment, including the aforementioned adjustable welding device. The dual-station welding equipment includes two adjustable welding devices and is provided with a first station 100 and a second station 200. The two adjustable welding devices form a dual-station combination, which is beneficial to improving production speed.

[0029] like Figures 2 to 6The height-adjustable welding device shown includes a frame 1 and a welding machine 2 housed within the frame 1. The welding machine 2 includes a welding body 21, with a laterally extending welding section 22 on its side. The welding machine 2 is connected to a lifting mechanism 3, which is used to move the welding machine 2 up and down. Because the welding machine 2 is fixed to the lifting mechanism 3, and the welding section 22 extends laterally from the side of the welding body 21, the lifting mechanism 3 drives the welding machine 2 to move up and down, thereby causing the welding section 22 to move up and down. This achieves automatic height adjustment, enabling multi-stage welding and significantly improving efficiency.

[0030] As a specific embodiment and not a limitation, the lifting mechanism 3 includes a lifting screw 31. One end of the lifting screw 31 is connected to a drive mechanism 32, and the other end is fitted with a nut seat 33. The drive mechanism 32 is used to rotate the lifting screw 31, thereby driving the nut seat 33 to move along the axial direction of the lifting screw 31. The nut seat 33 is fixed to the welding machine 2 and is used to drive the welding machine 2 to perform lifting and lowering movements. Since the welding machine 2 is fixed to the nut seat 33 on the lifting mechanism 3, when the drive mechanism 32 of the lifting mechanism 3 rotates the lifting screw 31, the nut seat 33 moves along the axial direction of the lifting screw 31, thereby driving the welding machine 2 to perform lifting and lowering movements, thus realizing automatic lifting and lowering adjustment. The drive mechanism 32 can be a stepper motor or a servo motor.

[0031] As a specific implementation and not a limitation, to make the welding machine 2 more stable when moving along the lifting screw 31, the welding machine 2 further includes a support assembly 23 for mounting the welding machine body 21, and the lifting mechanism 3 further includes a guide rail 34 arranged along the length direction of the lifting screw 31. The guide rail 34 is provided with a slider 35 that can move axially along the guide rail 34, and the slider 35 is fixedly engaged with the support assembly 23. Two guide rails 34 are provided in the lifting mechanism 3, respectively located on both sides of the lifting screw 31. Each guide rail 34 is provided with a slider 35, which can slide along the guide rail 34. The slider 35 is fixed to the support assembly 23. When the nut seat 33 drives the welding machine 2 to move, the slider 35 on the guide rail 34 acts as an auxiliary sliding structure, making the welding machine 2 more stable when moving along the lifting screw 31.

[0032] Furthermore, to enable the welding equipment to monitor the temperature of the workpiece in real time, a detection mechanism 4 is included. The detection mechanism 4 includes a temperature probe 41 and a PID controller electrically connected to the temperature probe 41. The temperature probe 41 is used to detect the temperature of the workpiece. The temperature probe 41 is mounted on the frame 1 and located directly above the welding section 22. The temperature probe 41 is an infrared temperature sensor controlled by the PID controller. When the temperature reaches the set temperature, the equipment will cut off the power to protect the equipment. For example, when processing copper, if the copper welding temperature reaches 300 or 400 degrees Celsius or higher, the equipment will stop operating. The PID controller can also precisely control the power of the heating element according to the set temperature curve to ensure consistent product quality.

[0033] As a specific implementation and not a limitation, to enable the equipment to adapt to workpieces of different sizes, the welding machine body 21 is provided with mounting holes 211, and the welding part 22 includes a welding induction coil 221. The welding induction coil 221 extends with a plug-in post 222, which is fixed in place with the mounting hole 211. Electrodes are provided on the welding machine body 21, and the plug-in post 222 is in communication with the electrodes on the welding machine body 21. When different sizes of workpieces need to be processed, simply replacing the welding coil 22 is sufficient, thus adapting to different sizes of workpieces. Furthermore, when the plug-in post 222 is in communication with the electrodes on the welding machine body 21, current flows through the welding induction coil 221, generating a magnetic field. This magnetic field acts on conductive or magnetic materials, inducing eddy currents within them. Due to the resistance, these eddy currents generate heat, thereby heating the metal material to its melting point, thus achieving welding and fixing.

[0034] Furthermore, a blowing mechanism 6 is fixedly installed on the frame 1. The blowing mechanism 6 includes an air blowing pipe 61 and a helium blowing pipe 62, both of which are bamboo-joint tubes. The direction can be adjusted by adjusting the pipe body. In this blowing mechanism 6, the air blowing pipe 61 can blow out air to cool the workpiece to be processed. The temperature of the workpiece to be processed is controlled within a suitable range by a PID controller. The helium blowing pipe 62 can deliver helium to the workpiece to be processed during welding to form a protective layer on the surface of the workpiece and prevent it from being oxidized.

[0035] As one embodiment and not a limitation, the support assembly 23 includes a support plate 231 for mounting the welding machine body 21 and a side plate 232 perpendicularly disposed to the support plate 231. The side plate 232 is fixed to the slider 35 and the nut seat 33, respectively. A reinforcing plate 233 is also provided between the side plate 232 and the support plate 231 to increase the strength between the side plate 232 and the support plate 231 to support the placement of the welding machine body 21.

[0036] Furthermore, to facilitate the installation of the workpiece, the frame 1 includes a work platform 11, on which a clamping mechanism 5 for fixing the workpiece is provided. The clamping mechanism 5 includes a mounting base 51 movable along the plane of the work platform 11, and the mounting base 51 is provided with quick-release fixing posts 52 for fixing the workpiece. This mounting base 51 is a plane-movable adjustable base; adjustment is achieved simply by rotating the adjustment knob on the mounting base. Secondly, the mounting base 51 is also provided with quick-release fixing posts 52. The workpiece is inserted into the quick-release fixing posts 52 and then fixed by them. Furthermore, the plane-movable adjustable feature is designed to adjust the position of the workpiece to accommodate welding points at different locations.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
