Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy cylinder cover processing, in particular to a water jacket semi-through hole aluminum chip removing tool. Background Art

[0002] How to reduce the size of aluminum chips? The more mature application in the industry is to add chip breaker or chip splitter grooves on the tool to make the aluminum chips smaller and easier to clean in the cleaning machine. For the current similar cylinder head front and rear end water blocking cover hole 1 structure, there is a small platform structure at the bottom, and the bottom is not a full through hole, there is a channel that can lead to the water jacket 2 (such as Figure 1 As shown), this leads to the cutting fluid in the machining direction (as shown) during the tool machining process. Figure 2 The arrow indicates the direction of the internal coolant spray, flushing the aluminum chips generated during machining into water jacket 2, where they accumulate. Furthermore, because the water blocks the small platform at the bottom of cover hole 1, this semi-through hole structure cannot utilize the tool's reverse flushing design to remove the aluminum chips.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0025] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] Please refer to Figure 3 and Figure 4 The present invention proposes a water jacket semi-through hole aluminum chip removal tool 10. The preferred embodiment of the water jacket semi-through hole aluminum chip removal tool 10 includes a tool rod 101, and a plurality of spiral side blades 102 are arranged in parallel on the upper part of the tool rod 101. An end blade 103 is arranged on the top of the tool rod 101, and a chip dividing groove 104 is provided on both the side blade 102 and the end blade 103.

[0027] In this embodiment, a chip dividing groove 104 is added to the side edge 102 and a chip dividing groove 104 is also added to the end edge 103, so that the tool can optimize the aluminum chips in the bottom hole and the side wall when processing the semi-through hole, making them smaller.

[0028] Furthermore, in this embodiment, the chip-splitting grooves 104 on two adjacent side cutting edges 102 and the chip-splitting grooves 104 on two adjacent end cutting edges 103 are staggered. That is, the chip-splitting grooves 104 on two adjacent side cutting edges 102 and the chip-splitting grooves 104 on two adjacent end cutting edges 103 are staggered and not on the same circumference. This allows the chip-splitting grooves 104 on the side cutting edges 102 and the end cutting edges 103 to be used to break up the aluminum chips during machining, thereby minimizing the amount of aluminum chips produced during machining.

[0029] Furthermore, in this embodiment, the chip-splitting grooves 104 on the side cutting edge 102 and the chip-splitting grooves 104 on the end cutting edge 103 are arc-shaped grooves. In this embodiment, the chip-splitting grooves 104 on the side cutting edge 102 and the chip-splitting grooves 104 on the end cutting edge 103 are configured as arc-shaped grooves, which can effectively achieve the effects of anti-chipping and smooth chip removal, thereby increasing the service life of the tool and preventing aluminum sticking.

[0030] like Figure 5 and Figure 6 As shown, when using the water jacket semi-through hole aluminum chip removal tool 10 of this embodiment, a milling-first followed by a milling-around process is employed, effectively utilizing the chip dividing groove 104 on the tool to shred aluminum chips, thereby reducing the size of the aluminum chips. Specifically, the end blade 103 and chip dividing groove 104 are first used to break up aluminum chips at the bottom of the hole, and then the side blade 102 and chip dividing groove 104 are used to break up aluminum chips on the sidewall during milling.

[0031] The aluminum chip cutter 10 of the water jacket semi-through hole of this embodiment has high processing flexibility. In addition to being applicable to processing semi-through hole structures, it can also be effectively applied to processing full blind holes and full through holes.

[0032] The beneficial effects of the water jacket semi-through hole aluminum chip removal tool of the utility model are:

[0033] The utility model adopts the above technical solution, including: a tool rod, a plurality of spiral side blades are arranged in parallel on the upper part of the tool rod, an end blade is arranged on the top of the tool rod, and chip dividing grooves are provided on the side blades and the end blades, which can effectively reduce the shape and size of aluminum chips generated during the processing of the semi-through hole on the aluminum alloy cylinder head and the hole system connected to the water jacket, and prevent the aluminum chips from entering the water jacket.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present invention.
