Description

Technical Field

[0001] This utility model relates to the field of tool welding technology, specifically a PCB-specific tool welding device. Background Technology

[0002] PCB tool soldering is a process used to connect tool bits to the tool body. In the soldering process, specialized soldering equipment and materials are usually used. First, the soldering areas of the tool body and tool bits are cleaned and pre-treated to ensure the purity and good wettability of the soldering surface. Then, the tool bits are placed on the tool body, and a high-temperature heat source is used to melt the soldering material (such as silver-based solder) and fill the gap between the tool bits and the tool body. After cooling and solidification, a strong connection is formed.

[0003] Currently, during the soldering process of PCB cutting tools, it is not easy to accurately position the cutting blade and the cutting disc, which reduces the soldering accuracy between the cutting blade and the cutting disc. This is not conducive to maintaining stable performance of the cutting disc during high-speed cutting, and reduces cutting efficiency and accuracy. To address this, we propose a PCB-specific cutting tool soldering device. Utility Model Content

[0004] The purpose of this invention is to provide a PCB-specific tool welding device that facilitates precise positioning of the cutting disc and cutting blade during the PCB tool welding process, improves the welding accuracy of the cutting blade and cutting disc, and enhances the stability of the cutting disc during high-speed cutting, thereby improving cutting efficiency and accuracy. This invention solves the problem that in current PCB tool welding processes, it is difficult to accurately position the cutting blade and cutting disc, which reduces the welding accuracy between the cutting blade and cutting disc, hinders the stable performance of the cutting disc during high-speed cutting, and reduces cutting efficiency and accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB-specific tool welding device, comprising a fixed base, wherein a first sliding groove and a second sliding groove are respectively provided on the upper surface of the fixed base near the front and rear surfaces; a first bidirectional lead screw is installed inside the first sliding groove; a first threaded slider is sleeved on the outer surface of the first bidirectional lead screw near both ends; a clamping arm is connected to the upper surface of each of the two first threaded sliders via a connecting column; a second bidirectional lead screw is installed inside the second sliding groove; a second threaded slider is sleeved on the outer surface of the second bidirectional lead screw near both ends; a fixing frame is installed on the upper surface of each of the two second threaded sliders; and a rotating clamping plate is provided on the inner side of each of the two fixing frames.

[0006] Preferably, a first moving motor is installed on one side of the outer surface of the fixed base near the front surface, and the end of the output shaft of the first moving motor is connected to the end of the first bidirectional lead screw.

[0007] Preferably, a second moving motor is installed on one side of the outer surface of the fixed base near the rear surface, and the end of the output shaft of the second moving motor is connected to the end of the second bidirectional lead screw.

[0008] Preferably, a rotary motor is installed on the outside of the fixing frame, and the end of the output shaft of the rotary motor is connected to the outside of the rotating clamp.

[0009] Preferably, circular positioning protrusions are installed on the inner sides of both rotating clamps.

[0010] Preferably, each of the two clamping arms has a groove near its end on its inner side, and a clamping block is provided inside each of the two grooves. Each of the two clamping arms has a threaded hole near its end on its outer side, and an adjusting screw is inserted into each of the two threaded holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting a fixed base, a first sliding groove, a first bidirectional lead screw, a first threaded slider, a clamping arm, a second sliding groove, a second bidirectional lead screw, a second threaded slider, a fixed frame, and a rotating clamping plate, achieves the effect of facilitating the precise positioning of the cutting disc and the cutting blade during the PCB cutting process, improving the welding accuracy of the cutting blade and the cutting disc, and enhancing the stability of the cutting disc during height cutting, thereby improving cutting efficiency and accuracy. The rotation of the second bidirectional lead screw causes the two second threaded sliders to move in opposite directions, and the two rotating clamping plates position and clamp the two sides of the cutting disc in place. The rotation of the first bidirectional lead screw causes the two first threaded sliders to drive the two clamping arms to move in opposite directions, and position and clamp the two sides of the cutting blade on the cutting disc in place, and then the cutting blade is welded to the cutting disc.

[0013] 2. This utility model achieves the effect of positioning and clamping the cutting disc by setting circular positioning protrusions. When the two rotating clamping plates clamp and fix the two sides of the cutting disc, the two circular positioning protrusions are inserted into the center hole of the cutting disc from both sides to play a positioning role.

[0014] 3. By setting grooves, clamping blocks, threaded holes, and adjusting screws, this utility model achieves the effect of fine-tuning the position of the cutting blade during the positioning and clamping process, thereby further improving the positioning accuracy of the cutting blade and the cutting disc. By turning the two adjusting screws and moving the two clamping blocks, the position of the positioning and clamping cutting blade can be fine-tuned. Attached Figure Description

A first moving motor 5 is installed on one side of the outer surface of the fixed base 1 near the front surface, and the end of the output shaft of the first moving motor 5 is connected to the end of the first bidirectional lead screw 3. The first moving motor 5 drives the first bidirectional lead screw 3 to rotate. First threaded sliders 4 are sleeved on the outer surface of the first bidirectional lead screw 3 near both ends.
