The following requirements are imposed on the processing of the window: First, the roughness requirement of the window side wall: the roughness of the window side wall is within a relatively small range; second, the requirement of the horizontal lines of the window: assuming that the window opening direction is the Y direction, the Z direction is in the Y direction, and the horizontal lines of the window are required to be in the Z direction; third, the sealing function requirement: the window side wall is required to have a sealing function. The processing of the workpiece to be processed requires the use of the processing technology of the window of the workpiece to be processed.
[0003] In the prior art, the processing technology of the workpiece window to be processed includes the following steps: first, pressing the milling cutter into the inner wall of the window from a direction perpendicular to the Y direction; second, rotating the milling cutter to mill the inner wall of the window to obtain a milled window.
[0004] In the above-mentioned processing technology of the window of the workpiece to be processed, since the window is a special-shaped structure, the window can only be processed by milling. However, after milling, the lines formed on the window are vertical lines, and the vertical lines are parallel to the Y direction, which causes the seal to easily slip off the window when the window is sealed, that is, it has no sealing function. Summary of the invention
[0005] The present invention aims to provide a sealing window special-shaped pattern processing tool and a workpiece window processing technology, so as to solve the problem that the window has no sealing function due to the window processing by milling in the prior art.
[0006] To achieve the above object, the present invention adopts the following technical solutions: The present invention firstly discloses a sealable window special-shaped pattern processing tool, comprising: a tool holder, a first tooth block and a second tooth block, wherein the tip of the tool holder is provided with the first tooth block and the second tooth block spaced apart from each other, the first tooth block forms a first blade on the side away from the tool holder axis, and the second tooth block forms a second blade on the side away from the tool holder axis, a first notch is provided at the first blade, and a second notch is provided at the second blade, the first notch and the second notch are staggered in the Y direction, and the tool holder axis is located in the Y direction.
[0007] Preferably, the first blade forms a first wave line due to the first notch, and the trough of the first wave line is the first notch; the second blade forms a second wave line due to the first notch, and the trough of the second wave line is the second notch.
[0008] Preferably, the length of a wave crest and wave trough cycle in the first wave line is L1, the length of a wave crest and wave trough cycle in the second wave line is L2, and L1 is smaller than L2.
[0009] Preferably, the height difference between the crest and the trough in the first wave line is h1; the height difference between the crest and the trough in the second wave line is h2, and h1<h2.
[0010] The present invention also discloses a workpiece window processing technology, the workpiece window processing technology is based on the sealable window special-shaped pattern processing tool as claimed in any one of claims 1 to 4; The workpiece window processing process comprises the following steps: S1, pressing the first cutting edge on the first tooth block or the first cutting edge on the second tooth block onto the inner wall of the window in the workpiece to be processed; S2, rotationally driving the sealable window special-shaped pattern processing tool to mill the inner wall of the window in the workpiece to be processed, and obtaining the inner wall of the window with vertical patterns and horizontal patterns after milling, wherein the horizontal patterns are formed at the offset between the first notch and the second notch.
[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present application, a first notch is formed on the first blade in the first tooth block, and a second notch is formed on the second blade in the second tooth block, and the first notch and the second notch are staggered in the Y direction (the axis of the tool holder is located in the Y direction). When the entire sealable window special-shaped pattern processing tool is driven to rotate, annular horizontal patterns located in the Z direction can be formed at the first notch and the second notch, thereby realizing the milling of the special-shaped window using the milling sealable window special-shaped pattern processing tool to improve the accuracy of the window, and realizing the formation of horizontal patterns on the inner wall of the window, so that the inner wall of the window has the function of limiting the separation of the seal from the window in the Y direction through the horizontal patterns, thereby ensuring that the sealing function can be safely realized.

[0019] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments: Example 1
[0020] like Figures 3 to 5 As shown, the present embodiment discloses a sealable window profile pattern processing tool, comprising: a tool holder 1, a first tooth block 2 and a second tooth block 3, the tip of the tool holder 1 is provided with the first tooth block 2 and the second tooth block 3 spaced apart from each other, the first tooth block 2 forms a first blade 21 on the side away from the axis of the tool holder 1, the second tooth block 3 forms a second blade 31 on the side away from the axis of the tool holder 1, a first notch is provided at the first blade 21, a second notch is provided at the second blade 31, the first notch and the second notch are staggered in the Y direction, and the axis of the tool holder 1 is located in the Y direction.
[0021] The first blade 21 forms a first wave line due to the first notch, and the first wave line trough is the first notch. The second blade 31 forms a second wave line due to the first notch, and the second wave line trough is the second notch. The first notches arranged evenly are formed at the first blade 21, and the second notches arranged evenly are formed at the second blade 31. There are at least two first notches and second notches, so that a plurality of horizontal circular lines located in the Z direction are formed on the inner wall of the window 4. The horizontal lines have the function of preventing the seal from detaching during sealing.
[0022] The length of a wave crest and trough cycle in the first wave line is L1, and the length of a wave crest and trough cycle in the second wave line is L2, and L1 is smaller than L2. By controlling L1 and L2, the first notch and the second notch can be staggered in the Y direction, thereby controlling the height of the horizontal lines in the Y direction.
[0023] The height difference between the crest and trough of the first wave line is h1; the height difference between the crest and trough of the second wave line is h2, h1<h2. By controlling the difference between h1 and h2, the thickness of the annular horizontal lines can be controlled. Simultaneously controlling the h1 value and the h2 value can meet the roughness requirements of the inner wall of the window 4. Example 2
[0024] This embodiment discloses a workpiece window 4 processing technology, and the workpiece window 4 processing technology is based on the sealable window 4 special-shaped pattern processing tool as described in Example 1; The workpiece window 4 processing process includes the following steps: S1, pressing the first cutting edge 21 on the first tooth block 2 or the first cutting edge 21 on the second tooth block 3 onto the inner wall of the window 4 in the workpiece to be processed; S2, the sealable window 4 special-shaped pattern processing tool is rotationally driven to mill the inner wall of the window 4 in the workpiece to be processed, and the inner wall of the window 4 with vertical and horizontal patterns is obtained after milling, and the horizontal patterns are formed corresponding to the misalignment of the first notch and the second notch.
