Description

Technical Field

[0001] The utility model relates to the technical field of welding machine adjustment devices, in particular to a welding seat adjustment guide device of a welding machine. Background Art

[0002] High frequency welding machine uses high frequency electric field to make the internal molecules of plastic oscillate to generate heat energy to fuse various products. The positively charged molecules of dielectric material are activated under the action of high frequency electric field, making the positively charged molecules of dielectric material move at high speed, and friction generates heat to weld the plastic.

[0003] Existing high-frequency welding machines usually include a working platform, a welding head assembly and a cylinder, wherein the cylinder is arranged on the welding head assembly. Before welding, the cylinder drives the welding head to descend and contact with the upper surface of the raw material, and then the high-frequency oscillation electrical box generates an electromagnetic wave current electric field, so that the molecules inside the raw material collide violently with each other to generate high temperature to achieve the purpose of welding. However, in practice, the welding head cannot be stably pressed on the raw material, and its working stability is low.

[0004] A boosting structure and a high-frequency welding machine thereof are disclosed in a patent document with Chinese patent application number 202220480475.5 and announcement date 2022.10.21, which can improve working stability. Among them, a boosting structure includes a lever linkage mechanism and a boosting drive mechanism. Before welding, the control part of the lever linkage mechanism drives the welding head to complete the first stage of activity in the direction of approaching the raw material to be processed, so that the welding head is in contact with the upper surface of the raw material. Then, the control part is driven by the boosting drive mechanism to further drive the welding head in the direction of approaching the raw material to be processed to complete the second stage of activity. In this way, the pressure of the welding head on the raw material to be processed can be increased, so that the welding head can be pressed more stably on the upper surface of the raw material, thereby improving its working stability.

[0005] However, the welding head of the document is directly connected to the transmission lever, so that the welding head can only be moved by rotating the transmission lever, but the pressing distance of the welding head to the table surface of the machine cannot be fine-tuned, thereby failing to achieve fine-tuning of the height of products of different heights and sizes, and failing to adapt to the use of workpieces of different sizes. Summary of the invention

[0006] The utility model provides a welding seat adjusting guide device of a welding machine, which can finely adjust the height of a pressurizing piece according to the size of a processed workpiece, so as to adapt to different kinds of workpieces.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a welding seat adjustment guide device of a welding machine, which is arranged on the welding machine, including a pressure device and an adjustment guide device, the pressure device is arranged on a driving component of the welding machine through the adjustment guide device, the driving component drives the pressure device to weld the workpiece, the adjustment guide device is arranged on the frame of the welding machine, the adjustment guide device includes a driving cross bar and an adjusting component, the driving cross bar is rotatably arranged on the frame through a cross bar shaft, one end of the driving cross bar is connected to the driving component, and the adjusting component is arranged at the other end of the driving cross bar; the pressure device includes a pressure rod, the pressure rod is movably connected to the driving cross rod through an adjusting component, the adjusting component is connected to the pressure rod and the adjusting component is movably arranged along the up and down directions of the pressure rod, a pressure piece for welding the workpiece is provided below the pressure rod, and the driving cross rod drives the pressure rod to press down to complete the contact between the pressure piece and the workpiece.

[0008] The above structure enables the pressure device to be adjusted by arranging an adjustment guide device between the driving component and the pressure device. When the pressure device needs to be fine-tuned, the pressure rod is rotated to make the pressure rod move up and down on the adjusting component, so that the adjusting component moves slightly on the driving cross bar to provide activity space, so that the pressure rod drives the pressure piece to be fine-tuned up and down, thereby making the adjustment guide device able to adjust the height of the pressure device according to the size of the workpiece, so that it can adapt to different types of workpieces. Since the adjusting component can be moved up and down along the pressure rod, the adjusting component can be set on the driving cross bar, and then the pressure rod is adjusted, so that the pressure rod can move up and down, thereby adjusting the height of the pressure piece. This will not affect the driving component to drive the pressure piece to press down, and the pressure piece can be adjusted downward and upward. The structure is simple and reliable.

[0009] Furthermore, the adjusting component includes an adjusting nut, a thread corresponding to the adjusting nut is provided on the rod body of the pressure rod, the adjusting nut is arranged to move along the up and down directions of the pressure rod, and the pressure rod is detachably connected to the pressure piece.

[0010] With the above arrangement, by setting the adjusting nut, when the operator rotates the pressure rod, the connection position between the pressure rod and the adjusting nut is driven to move through the connection between the thread and the adjusting nut, thereby adjusting the height of the pressure rod.

[0011] Furthermore, the pressurizing device also includes a pressurizing base, which is arranged on the frame, and a first guide hole is provided on the pressurizing base, which runs from the top end to the bottom end of the pressurizing base. The pressurizing rod is located in the first guide hole and is arranged to move up and down along the first guide hole. A cavity is provided in the middle of the pressurizing base, which passes through both ends of the pressurizing base. The other end of the driving cross rod extends into the cavity and is connected to an adjusting component arranged on the pressurizing rod. The driving cross rod drives the pressurizing rod to move up and down along the first guide hole.

[0012] The above arrangement, through the function of the first guide hole, enables the pressure rod to play a guiding role when moving up and down, thereby preventing the pressure rod from deviating.

[0013] Furthermore, second guide holes are provided on the pressurizing base on both sides of the first guide hole, and a guide shaft is provided in the second guide hole, and the top end of the guide shaft is connected to the top end of the pressurizing rod through a guide connecting plate.

[0014] The above arrangement, through the action of the guide shaft, can further enhance the guidance of the pressure rod when it moves up and down, and prevent the pressure rod from deflecting.

[0015] Furthermore, an open slot is provided at the other end of the driving cross bar, and limit blocks are provided on both sides of the adjusting nut. The limit blocks are arranged in the open slot and slide along the length direction of the open slot.

[0016] The above arrangement, through the effect of the open slot, enables the adjusting nut to be connected to the driving cross bar while ensuring that the movement of the adjusting nut is not restricted, thereby facilitating the up and down movement of the pressure rod.

[0017] Furthermore, the crossbar shaft is mounted on the frame via a cotter pin.

[0018] The above arrangement can not only ensure stable installation of the crossbar shaft through the cotter pin, but also facilitate disassembly when necessary.

[0019] Furthermore, an adjusting button is provided at the upper end of the pressing member.
