Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining tool technology, specifically to a T-slot machining tool for silicon components. Background Technology
[0002] Silicon components refer to electronic or mechanical parts made primarily of silicon, and are widely used in semiconductors, integrated circuits, solar cells, sensors, and other fields. Silicon's unique physical and chemical properties (such as semiconductor characteristics, high stability, and ease of processing) have made it a core material in the modern electronics industry.
[0003] Some silicon components require mounting holes to be machined on their surface after production. The machining of these mounting holes is also known as T-slot machining. First, a drill bit is used to drill a hole on the surface. Then, different milling cutters are used to mill and enlarge the hole on the surface of the silicon component. After the hole milling is completed, a chamfering cutter is used to mill a chamfered surface on the top of the hole, thus completing the T-slot machining process.
[0004] However, in the process of milling holes, expanding holes, and chamfering surfaces, different tools need to be changed for each process. After changing tools, the positioning accuracy of the tool on the workpiece is easily affected, and tool wear is likely to occur as the tool is processed. If tool compensation is not adjusted in time during multiple tool changes, the machining accuracy of the tool on the workpiece is more likely to be affected. Tool marks (tool change marks) are likely to appear in the T-slot after tool change, which can affect the machining accuracy of the T-slot and cause a decrease in yield. Utility Model Content
[0005] The purpose of this invention is to provide a T-groove machining tool for silicon components, addressing the deficiencies and shortcomings of existing technologies.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a T-groove machining tool for silicon components, including a tool holder, a connecting part disposed on the tool holder, and a machining head disposed on the connecting part. The machining head includes a chamfered cutting face and a flat cutting face. The connecting part is connected to one end of the chamfered cutting face, and the flat cutting face is connected to the other end of the chamfered cutting face. A hole-enlarging cutting face is provided on the side periphery of the flat cutting face.
[0007] A further improvement is that a clearance cone surface is provided between the connecting part and the tool holder.
[0008] A further improvement is that the flat-bottomed blade and the chamfered blade are integrally formed.
[0009] A further improvement is that the flat-bottomed blade, the chamfered blade, and the reaming blade are provided with a sandblasting layer.
[0010] A further improvement is that the sprayed layer is a diamond sand layer or a quartz sand layer.
[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: After drilling a hole on the surface with a drill bit, the improved tool of this application is replaced by a machining center to perform hole opening, hole reaming, and chamfering. During the machining process, the surface is first opened with a flat-bottomed tool face. After the hole opening is completed, the tool is controlled by the program to make the flat-bottomed tool face and the reaming tool face perform hole reaming. During the hole reaming process, the chamfering tool face will contact the workpiece, thereby forming the hole reaming and chamfering processes to be carried out simultaneously. The hole opening, hole reaming, and chamfering processes of T-slots can be completed without changing the tool. The positioning accuracy of the tool on the workpiece will not be affected by tool changing, and there is no need to consider the compensation effect of the tool changing step on the tool. Tool marks (tool changing marks) are not likely to appear during machining, thus not easily affecting the machining accuracy of the T-slots and not easily causing a decrease in yield.
[0012] Further benefits: The connecting part serves to avoid contact with the workpiece when milling and enlarging holes on the flat-bottomed cutter face, thereby enabling the enlarging operation to be performed at the side edge position of the flat-bottomed cutter face.
[0013] Further benefits: The avoidance cone not only avoids the workpiece surface when the tool is machining to the depth, but also plays a chamfering role when chamfering is required at the junction of the workpiece surface and the T-slot surface. It can achieve part of the machining requirements of the T-slot on a single tool.
[0014] Further benefits: After sandblasting the flat-bottomed and chamfered cutting edges, a uniform, fine-grained texture is formed on the tool surface, increasing surface hardness, raising the coefficient of friction, improving wear resistance, and extending service life. Sandblasting also removes burrs, rust, oxide layers, and other impurities from the tool surface, making it smoother and more uniform. This is especially important for tools requiring precision contact (such as measuring tools and cutting tools), reducing errors and friction caused by surface unevenness, thereby improving tool accuracy. Attached Figure Description
[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Explanation of reference numerals in the attached drawings: 1. Tool holder; 2. Connecting part; 3. Chamfered cutting face; 4. Flat bottom cutting face; 5. Avoidance cone surface; 6. Sandblasting layer; 7. Hole enlarging cutting face. Detailed Implementation
[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0019] See Figures 1 to 3 As shown, the technical solution adopted in this specific embodiment is: a T-groove machining tool for silicon components, including a tool holder 1, a connecting part 2 disposed on the tool holder 1, and a machining head disposed on the connecting part 2. The machining head includes a chamfered cutting face 3 and a flat bottom cutting face 4. The connecting part 2 is connected to one end of the chamfered cutting face 3, and the flat bottom cutting face 4 is connected to the other end of the chamfered cutting face 3. A hole-enlarging cutting face 7 is disposed on the side periphery of the flat bottom cutting face 4.
[0020] Because the machining dimensions of the T-slot need to be varied according to the specifications or usage requirements of the silicon component, the size of the T-slot is not uniformly fixed. Therefore, the length and diameter of the connecting part 2 need to be preset in advance based on the depth of the T-slot and the reaming distance. The taper of the chamfering face 3 also needs to be preset in advance based on the chamfer slope of the T-slot. The diameter of the flat-bottomed face 4 also needs to be set according to the opening diameter and reaming diameter of the T-slot. However, the maximum diameter of the chamfering face 3 is the same as the diameter of the flat-bottomed face 4, and the diameter of the reaming face 7 is the same as the diameter of the flat-bottomed face 4. The tool holder 1, connecting part 2, and machining head are integrally formed. The tool holder 1 is connected to the fixture of the tool changing center.
[0021] An abutment cone 5 is also provided between the connecting part 2 and the tool holder 1. The taper and length of the abutment cone 5 are set in advance according to the processing requirements. The abutment cone 5 is integrally formed with the tool holder 1, the connecting part 2, and the processing head.
[0022] The flat-bottomed blade 4 and the chamfered blade 3 are integrally formed.
[0023] A sandblasting layer 6 is provided on the flat-bottomed cutting surface 4, the chamfered cutting surface 3, and the reaming cutting surface 7.
[0024] The sprayed layer is a layer of corundum or a layer of quartz sand.
[0025] The working principle of this utility model is as follows: After drilling a hole on the surface with a drill bit, the improved tool of this application is replaced by a machining center to perform hole opening, hole enlargement, and chamfering. During the machining process, the surface is first opened by the flat-bottomed tool face 4. After the hole opening is completed, the tool is controlled by the program to enlarge the hole by the flat-bottomed tool face 4 and the hole enlargement tool face 7. During the hole enlargement process, the chamfering tool face 3 will contact the workpiece, so that the hole enlargement and chamfering are performed simultaneously. The hole opening, hole enlargement, and chamfering of the T-slot can be completed without changing the tool. The positioning accuracy of the tool on the workpiece will not be affected by the tool change, and there is no need to consider the compensation effect of the tool change step on the tool. Tool marks (tool change marks) are not likely to appear during the machining process, so the machining accuracy of the T-slot is not likely to be affected, and the yield rate is not likely to decrease. The connecting part 2 is used to avoid the workpiece when milling and enlarging the hole on the flat bottom cutter face 4, so that the side cutting edge of the flat bottom cutter face 4 can realize the enlarging operation. The avoidance cone 5 can not only avoid the workpiece surface when the tool is machining to the depth, but also play a chamfering milling role when it is necessary to chamfer the junction of the workpiece surface and the T-slot surface. It can achieve part of the machining needs of the T-slot on a single tool. After sandblasting the flat-bottomed face 4 and the chamfered face 3, a uniform, fine-grained texture is formed on the tool surface, increasing surface hardness, raising the coefficient of friction, improving wear resistance, and extending service life. Sandblasting also removes burrs, rust, oxide layers, and other impurities from the tool surface, making it smoother and more uniform. This is especially important for tools requiring precision contact (such as measuring tools and cutting tools), reducing errors and friction caused by surface unevenness, thereby improving tool accuracy.
