Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing technology, specifically a stable router tool device for printed circuit board processing. Background Technology

[0002] Printed circuit boards, commonly known as PCBs, are the support structure for electronic components and the provider of electrical connections. They are present in almost all electronic devices and are the cornerstone of the modern electronics industry. In the PCB industry, "milling cutter" is a common name for a milling cutter, specifically referring to the cutting tool used in PCB CNC milling machines. It is mainly used for milling the outline and chiseling slots and irregular holes.

[0003] The existing gong cutter has the following problems: Unstable installation of existing milling cutters is a common source of failure in PCB CNC milling, which can directly lead to a decline in processing quality or even scrapping. Utility Model Content

[0004] The purpose of this invention is to provide a stable router tool device for printed circuit board processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stable router tool device for printed circuit board processing, comprising a mounting head, a connecting rod connected to the mounting head, a cutting head provided at the end of the connecting rod, a pressure port structure provided on the connecting rod, the pressure port structure including a connection port, the connection port provided in the mounting head, a pressure block provided on the connecting rod, and a plug provided on the pressure block.

[0006] Preferably, the size of the plug is adapted to the size of the connector.

[0007] Preferably, the upper end of the plug is tapered.

[0008] Preferably, the diameter of the pressure block is larger than the diameter of the connection port.

[0009] Preferably, the pressure block is provided with an installation groove, and a pressure pad is assembled in the installation groove, and the pressure pad is elastic.

[0010] Preferably, when the pressure pad is in its natural, unforced state, its top surface protrudes beyond the top surface of the pressure block.

[0011] Preferably, a retaining ring is provided in the mounting groove.

[0012] Preferably, a gasket is fixed in the pressure pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are: When the connecting rod mates with the mounting head, the plug is inserted into the connector along with the connecting rod. Since the size of the plug matches the size of the connector, the connector can suppress the plug from wobbling after mating, thus stabilizing the connecting rod and the cutting head and preventing the cutting head from wobbling during rotation. Then, the pressure block presses on the surface of the mounting head. At this time, the pressure pad is compressed and generates elastic force. When the pressure block presses on the surface of the mounting head, it can prevent the cutting head from wobbling. At the same time, the pressure pad pressing on the surface of the mounting head can prevent the machining debris from entering the interior of the mounting head and generate a downward thrust, making the connection between the connecting rod and the mounting head more secure, so that the entire milling cutter has a high stability effect.

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a stable router tool device for printed circuit board processing, including a mounting head 1, which is also a rotating head of a PCB CNC milling machine. The mounting head 1 is driven to rotate by the PCB CNC milling machine, thereby driving the connecting rod 2, which is inserted and limited therein, to rotate. The end of the connecting rod 2 is integrally formed with a cutting head 3. Rotating the cutting head 3 can process the printed circuit board. The connecting rod 2 is provided with a pressure structure 4.

[0018] Please see Figure 3 , Figure 4 and Figure 5This utility model provides a stable router tool device for printed circuit board processing. The pressure structure 4 includes a connection port 41. The connection port 41 is provided at the connection between the mounting head 1 and the connecting rod 2. A pressure block 42 is integrally formed on the connecting rod 2. A plug 43 is provided on the pressure block 42. The size of the plug 43 is adapted to the size of the connection port 41 so that the plug 43 can be stabilized after it is connected to the connection port 41, effectively suppressing the phenomenon of the plug 43 shaking. In addition, the upper end of the plug 43 is tapered, which has a better connection effect.

[0019] The diameter of the pressure block 42 is larger than the diameter of the connection port 41, so that the pressure block 42 can press on the connection port 41 without being inserted into the connection port 41.

[0020] The pressure block 42 is provided with a mounting groove 44, and a pressure pad 45 is fitted in the mounting groove 44. The pressure pad 45 is elastic. When the pressure pad 45 is in a natural state without force, its top surface protrudes from the top surface of the pressure block 42. A retaining ring 46 is provided in the mounting groove 44 to hold the pressure pad 45 in the mounting groove 44 to prevent it from falling off when changing tools. A gasket 47 is fixed in the pressure pad 45 to give the pressure pad 45 a better pressure resistance.

[0021] Specifically, when the connecting rod 2 mates with the mounting head 1, the plug 43 is inserted into the connector 41 along with the connecting rod 2. Since the size of the plug 43 matches the size of the connector 41, the connector 41 can suppress the plug 43 from shaking after mating, thereby stabilizing the connecting rod 2 and the cutter head 3 and preventing the cutter head 3 from shaking during rotation. Then, the pressure block 42 presses on the surface of the mounting head 1. At this time, the pressure pad 45 is compressed and generates elastic force. When the pressure block 42 presses on the surface of the mounting head 1, it can prevent the cutter head 3 from shaking. At the same time, the pressure pad 45 pressing on the surface of the mounting head 1 can prevent the machining debris from entering the interior of the mounting head 1 and generate a downward thrust, making the connection between the connecting rod 2 and the mounting head 1 more secure, so that the entire milling cutter has a high stability effect.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
