Technical Field

[0001] This utility model relates to the technical field of drilling and milling fixtures, and particularly to a drilling and milling fixture. Background Technology

[0002] For products with a large number of glue inlets, high glue inlets, and high processing requirements, the current method typically involves CNC equipment to mill each glue inlet individually according to a programmed sequence. Ten glue inlets require ten milling operations, which is time-consuming and cannot meet production capacity needs. Furthermore, the equipment's processing accuracy is within ±5 micrometers. Given the high processing requirements of this product, significant fluctuations in equipment accuracy can lead to milling depths that are too shallow or too deep, resulting in a high defect rate, low production stability, and increased rework and scrap costs.

[0030] This utility model provides a drilling and milling fixture, which includes multiple drilling and milling components 21, each connected to a drive component 22. The drive component 22 drives the multiple drilling and milling components 21 to perform drilling and milling on the product. Compared to single milling in the prior art, this application can simultaneously complete the milling of multiple glue injection points, improving production efficiency. Furthermore, this application also includes a first mold 11 and a second mold 12. When the first mold 11 and the second mold 12 are closed, the first positioning post 31 and the second positioning post 32 abut against each other, ensuring precise positioning of the first mold 11 and the second mold 12 during the mold closing process. This avoids milling the product too deep or too shallow, thereby enabling rapid and accurate milling of multiple glue injection points, ensuring processing accuracy and stability, and increasing production capacity.

[0031] This application is applicable to products with a large number of glue inlet points, high glue inlet points, and high processing requirements.

[0032] In this embodiment, there are two of each of the first positioning post 31 and the second positioning post 32.

[0033] refer to Figures 3-4 The milling assembly 21 includes a gear 211, a tool holder 212, and a milling cutter 213.

The tool holder 212 is disposed at the bottom end of the gear 211, and the milling cutter 213 is disposed at the bottom end of the tool holder 212. The drive assembly 22 is used to drive the gear 211 to rotate, thereby driving the tool holder 212 and the milling cutter 213 to rotate.

[0034] Specifically, gear 211, tool holder 212 and milling cutter 213 are coaxially connected. Furthermore, gear 211 and tool holder 212 are fixed together by a ferrule, and milling cutter 213 is fixed to tool holder 212 by a ferrule, which facilitates adjustment of the height position of milling cutter 213.

[0035] refer to Figures 3-4 The drive assembly 22 includes a motor 221 and a conveyor belt. The motor 221 and the conveyor belt are disposed on the first mold 11.

[0036] Specifically, the conveyor belt is fitted around the outside of the motor 221 and the gear 211. The motor 221 drives the gear 211, the tool holder 212 and the milling cutter 213 to rotate together through the conveyor belt, thereby achieving the drilling and milling effect.

[0037] In this embodiment, the conveyor belt is a belt.

[0038] refer to Figure 3 and Figure 4The drive assembly 22 also includes a pressure roller 222, which is located on one side of the conveyor belt. The pressure roller 222 is used to press the conveyor belt to prevent it from slipping and spinning, thereby improving the transmission efficiency.

[0042] In the prior art, the milling cutter 213 of the equipment is vertically downward, while the surface of the product is curved, which causes the product surface and the milling cutter 213 to not maintain a perpendicular relationship, leaving a step on the surface of the machined product. This application solves this problem by setting a first connecting plate 111 and a second connecting plate 112 that are relatively inclined. The first connecting plate 111 is approximately parallel to the first machined surface of the product, and the second connecting plate 112 is approximately parallel to the second machined surface. Both the first and second machined surfaces are located on the top surface of the product. The first drilling and milling device 2 is set perpendicular to the first connecting plate 111, and the second drilling and milling device 2 is set perpendicular to the second connecting plate 112. This ensures that each milling cutter 213 maintains a relatively perpendicular relationship with the machined surface of the product, thus guaranteeing the machining effect.

A second motor 221 is perpendicular to the second motor fixing plate 223. There are four pressure rollers 222. A drilling and milling assembly 21 is arranged between two adjacent sets of pressure rollers 222.

[0045] Specifically, the first mold 11 also includes two connecting steel bars 113. The connecting steel bars 113 are disposed on the top surface of the second connecting plate 112. The two connecting steel bars 113 are respectively disposed on opposite sides of the second connecting plate 112, and the connecting steel bars 113 extend from the end of the second connecting plate 112 away from the first connecting plate 111 to the end of the first connecting plate 111 away from the second connecting plate 112.

[0046] refer to Figure 2 and Figure 3 The first mold 11 also includes a first support column 114 and a first mounting plate 115.

The first housing 116 is disposed at the bottom end of the first connecting plate 111 and the second connecting plate 112. The second mold 12 includes a second housing 121. When the first mold 11 and the second mold 12 are closed, the first housing 116 and the second housing 121 are joined to form a sealed accommodating cavity.

[0049] Specifically, both the first shell 116 and the second shell 121 are made of acrylic.
