Description

Technical Field

[0001] This utility model relates to the field of tap technology, specifically an internally cooled carbide tap with an axial cooling channel. Background Technology

[0002] A tap is a cutting tool used to machine internal threads. It is widely used in machinery manufacturing, automotive industry, aerospace and other fields, and is an indispensable tool in thread machining. It uses a rotary cutting method to machine internal threads that meet specifications in the hole of a workpiece (such as metal, plastic and other materials), so that the workpiece can achieve a precise fit with the corresponding external threaded parts (such as bolts and studs).

[0003] An existing patent (publication number: CN214350080U) discloses a diamond-coated cemented carbide tap. By machining the first, second, and third chip removal grooves on the surface of the tap, the space for chip removal and heat dissipation is increased, further enhancing the chip removal and heat dissipation performance of the tap. This effectively solves the problems of the previous technology, which could not perform separate maintenance on the machined wire part, resulting in high maintenance costs. At the same time, the chip removal and heat dissipation performance of the tap was limited and the effect was not good during use. This ensures the efficient and stable use of the diamond-coated cemented carbide tap.

[0004] To address the aforementioned issues, while existing patents offer solutions that can dissipate heat through the cooperation of components such as the first chip removal groove, in actual use, if this integrated tap breaks even slightly, the entire unit needs to be replaced, resulting in high overall costs.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example 1

[0020] Please see Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides an internally cooled carbide tap with an axial cooling channel, including a tool holder 1, a connecting part 2, a machining part 3, a cooling channel 4, an internal cooling hole 5, a disassembly and assembly mechanism 6, and a reinforcement mechanism 7; The connecting part 2 is fixedly installed at the bottom end of the tool holder 1; The processing part 3 extends out of the bottom end of the connecting part 2; Cooling channel 4 is located inside tool holder 1; The internal cooling hole 5 is formed on the inner wall of the machining section 3; The disassembly and assembly mechanism 6 is located on the outside of the connecting part 2.

[0021] Specifically, the disassembly and assembly mechanism 6 includes an insertion block 601, which is fixedly installed on the top of the processing part 3. The connecting part 2 has a locking groove 602 corresponding to the position of the insertion block 601, and the outer wall of the connecting part 2 has a sliding groove 603.

[0022] Furthermore, the machining part 3 is integrated with the insertion block 601 and is inserted into the engagement groove 602 of the connecting part 2. The rectangular structure allows them to resist each other and maintain rotational torque during rotation.

[0023] Specifically, the inner wall of the slide 603 is provided with a slot 604, a connecting block 606 extends out of the slot 604, and a rotating plate 605 is fixedly installed on the outer wall of one end of the connecting block 606 that extends out of the slot 604.

[0024] Furthermore, by rotating and sliding the slot 604 and the connecting block 606 together, the position of the rotating plate 605 can be adjusted, thereby adjusting the length of the tap according to the requirements and improving the overall usability.

[0025] Specifically, a connecting ring 607 is slidably connected to one side of the outer wall groove 603 of the connecting part 2, and a positioning hole 608 is provided on the inner wall of the insert block 601.

[0026] Furthermore, after the rotating plate 605 is adjusted as required, it is inserted into the positioning hole 608 of the insert block 601 to achieve a positioning effect and prevent the insert block 601 from becoming loose or detached.

[0027] Specifically, the insert block 601 and the engaging groove 602 form a sliding structure, and the outer dimensions of the engaging groove 602 match the outer dimensions of the insert block 601.

[0028] Furthermore, the mutual contact between the insertion block 601 and the engaging groove 602 allows for convenient and quick assembly and disassembly of the connecting part 2 and the processing part 3. When the processing part 3 is damaged, it can be disassembled and replaced, avoiding the waste of replacing the whole part.

[0029] In use, the tool holder 1 can introduce condensate through the cooling channel 4 opened vertically and axially when fixed with machine tools and other equipment, and the condensate flows out through the internal cooling hole 5, thereby achieving the effects of lubrication and heat dissipation. The insertion block 601 of the machining part 3 is inserted into the locking groove 602 of the connecting part 2. After adjusting the position according to the requirements, the connecting block 606 is rotated and adjusted through the cooperation of the sliding groove 603 and the locking groove 604, so that the position of the rotating plate 605 is driven to enter the positioning hole 608, the insertion block 601 is positioned, and it is connected to the connecting part 2 by thread with the connecting ring 607. The position is adjusted to limit the four rotating plates 605, so that the connecting part 2 and the machining part 3 can be quickly assembled.

[0030] In summary, by adjusting and rotating the rotating plate 605, and finally positioning the insertion block 601 under the limit of the connecting ring 607, the connecting part 2 and the processing part 3 can be assembled or their length adjusted, improving the overall usability of the tap. It also allows for disassembly and replacement when the processing part 3 is damaged, avoiding the high cost of overall replacement. Example 2

[0031] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0032] Specifically, the reinforcement mechanism 7 includes a fixing plate 701, which is fixedly installed on the top of the connecting ring 607, and a fixing ring 702 is fixedly installed on the top of the fixing plate 701.

[0033] Furthermore, the fixed ring 702, driven by the fixed plate 701, moves in the same direction as the connecting ring 607, thereby increasing the range of the limiting position on the rotating plate 605 and further improving stability.

[0034] Specifically, the inner wall of the fixed ring 702 is provided with a rotating groove 703, and an abutment block 704 is rotatably connected inside the rotating groove 703.

[0035] Furthermore, by slidingly engaging the abutment block 704 with the rotating groove 703, the abutment block 704 can slide along the groove 603 when the fixed ring 702 rotates with the connecting ring 607, thereby abutting the rotating plate 605 from above and improving the overall stability.

[0036] Specifically, a connecting shell 705 is fixedly installed on the outer wall inside the connecting part 2 at the bottom end of the tool holder 1, and a sleeve shell 706 is slidably connected to the outside of the connecting shell 705.

[0037] Furthermore, the connecting shell 705 and the sleeve shell 706 form a telescopic structure, which can be inserted into the insertion block 601 to guide the coolant flowing through the cooling channel 4 into the processing section 3, and can extend and retract according to the position of the processing section 3 to maintain the flow of coolant.

[0038] In use, when the connecting ring 607 is displaced, the fixed ring 702 is driven to follow the displacement by the fixed plate 701, which increases the contact area with the rotating plate 605 and thus improves stability. At the same time, the contact block 704 is rotated and engaged with the rotating groove 703, so that it can slide along the slide groove 603 to contact the rotating plate 605 from above when the fixed ring 702 is displaced, thus preventing loosening. When the coolant enters the cooling channel 4, it is guided into the processing section 3 through the hollow connecting shell 705 and the sleeve shell 706. The connecting shell 705 and the sleeve shell 706 form a telescopic structure, which can adaptively adjust to the position of the processing section 3.

[0039] In summary, driven by the connecting ring 607, the fixed ring 702 can drive the abutment block 704 to abut against the rotating plate 605 from above. With the limiting effect of the positioning hole 608, the stability of the assembled processing part 3 can be further improved. At the same time, coolant is introduced into the processing part 3 through the connecting shell 705 and the sleeve shell 706, and it can adaptively adjust according to the position adjustment of the processing part 3, thereby improving the overall applicability and comprehensiveness.
