Description

Technical Field

[0001] This utility model relates to the field of air conditioning processing technology, and in particular to a positioning component and a gear hobbing cutter processing fixture mechanism. Background Technology

[0002] With the rapid development of modern industrial technology, the requirements for processing efficiency and precision are increasing. Especially in the field of air conditioning and refrigeration equipment, ventilated fins are highly favored due to their efficient heat exchange performance. The design of ventilated fins significantly improves heat exchange efficiency by increasing surface area and optimizing airflow paths, thereby enhancing the overall performance of the equipment. However, traditional ventilated fin processing mainly relies on die stamping technology. Although this method ensures processing precision to a certain extent, its inherent limitations are becoming increasingly apparent.

[0003] Currently, die stamping technology still requires high die costs. Due to the complex structure of the windowed fins, the design, manufacturing, and maintenance of the dies all require significant financial investment. Furthermore, to match the windowed structure, the dies are often large in size, which not only increases manufacturing costs but also causes inconvenience in storage and transportation.

[0004] Dies have a limited lifespan. During long-term stamping processes, they will wear down and deform, affecting processing accuracy and product quality. Therefore, companies need to frequently replace molds, which not only increases production costs but also extends production cycles and reduces production efficiency.

[0005] Die stamping technology also has certain limitations in flexibility. When it is necessary to process ventilated fins of different sizes or shapes, it is usually necessary to redesign and manufacture the die, which further increases production costs and time costs.

[0006] Therefore, in order to solve the many problems existing in the processing of windowed fins using traditional die stamping technology, in recent years, the method of using gear hobbing cutters with two different directions to roll the fins to form a windowed structure has gradually emerged. However, this method still faces some technical challenges in practical applications, such as the high processing difficulty, low efficiency, and difficulty in guaranteeing the accuracy of the gear hobbing cutters.

[0007] Specifically, the current method for processing multiple cutting tools simultaneously mainly involves gluing several identical tool blanks together. However, this leads to problems such as low precision of the hobbing cutting edge and the need to clean residual glue after processing, which increases additional steps and costs.

[0041] This utility model provides a positioning component and a hobbing cutter machining fixture mechanism to improve machining accuracy and efficiency.

[0042] The following is combined Figures 1-9 The technical solution provided by this utility model will be described in more detail.

[0043] This utility model provides a positioning component, including:

[0044] A fixing block 6 is disposed on one of the fixture base 2 and the fixture cover plate 3, and a plug-in block 8 is provided on the fixing block 6;

[0045] Positioning hole 9 is provided on the other side of the clamp base 2 and the clamp cover plate 3. The positioning hole 9 cooperates with the plug block 8 to position the clamp base 2 and the clamp cover plate 3.

[0046] A positioning structure is also provided on the fixing block 6, which is used to arrange the serrations of a plurality of cutting tools 13 to be processed in a stepped manner between the fixture base 2 and the fixture cover plate 3.

[0047] The positioning component provided by this utility model includes a fixing block 6 and a positioning hole 9. The fixing block 6 is disposed on one of the fixture base 2 and the fixture cover plate 3, and the positioning hole 9 is disposed on the other of the fixture base 2 and the fixture cover plate 3. A plug-in block 8 is provided on the fixing block 6. The positioning hole 9 cooperates with the plug-in block 8 to realize the positioning of the fixture base 2 and the fixture cover plate 3. By clamping the tool 13 to be processed by the fixture base 2 and the fixture cover plate 3, the positioning accuracy of the tool 13 to be processed can be ensured, and the processing accuracy of the tool edge can be ensured. Furthermore, due to the high positioning accuracy, at least two serrations of the tool 13 to be processed can be exposed. Each tool to be processed can be completed in one clamping. The machining of at least two cutting edges of the cutting tool 13 significantly improves production efficiency. A positioning structure is also provided on the fixing block 6, which allows the serrations of several cutting tools 13 to be machined to be stacked in a stepped manner between the fixture base 2 and the fixture cover plate 3. This enables the simultaneous machining of the cutting edges of several cutting tools 13, greatly improving machining efficiency while ensuring high precision of the machined cutting edges, meeting high-quality requirements. This avoids the problem of low cutting edge machining precision that exists in the prior art where several cutting tools 13 are glued together. Furthermore, it eliminates the need to clean residual glue after machining, simplifying the production process and significantly reducing costs and increasing efficiency.

[0048] It is understood that the serrations of several cutting tools 13 to be processed are stacked in a stepped manner between the fixture base 2 and the fixture cover plate 3. This means that several cutting tools 13 to be processed are stacked in sequence, and adjacent cutting tools 13 to be processed are set at a preset angle. This makes the serrations of several cutting tools 13 to be processed present a stepped distribution structure, ensuring that the cutting edge processing of several cutting tools 13 can be completed at the same time, and ensuring the consistency of product processing quality.

[0049] In some embodiments of this utility model, the positioning structure is a ramp-shaped positioning block 12, and any cross-sectional dimension of the positioning block 12 can be adapted to the groove dimension between two adjacent saw teeth of the tool to be processed 13.

After multiple tools 13 to be processed are stacked in sequence, the cutting edge of the tool 13 to be processed will be stepped. The cutting edge of each tool 13 to be processed is on the same horizontal working surface relative to the grinding wheel 14, which facilitates the processing of the cutting edge of each tool 13 to be processed.

[0052] In some embodiments of this utility model, the positioning structure includes a plurality of positioning bosses, which are arranged in a stepped manner, and the plurality of positioning bosses are respectively adapted to the grooves between two adjacent saw teeth of the plurality of stacked cutting tools 13 to be processed.

[0054] It should be noted that the positioning bosses are arranged in a stepped manner, which requires each positioning boss to correspond to a tool 13 to be processed, ensuring that each tool 13 to be processed can be arranged in a stepped layer, which places high precision requirements on the positioning bosses.

[0055] In some embodiments of this utility model, a central positioning post 5 is also included. The central positioning post 5 is disposed on one of the fixture base 2 and the fixture cover plate 3. The central positioning post 5 is disposed in correspondence with the central holes of a plurality of cutting tools 13 to be processed.

[0057] In some embodiments of this utility model, the central positioning post 5 is an arc-shaped structure.

[0058] In some of the embodiments of this utility model described above, the central positioning post 5 is an arc-shaped structure. The arc-shaped structure can realize the positioning of the tool 13 to be processed and can ensure that the tool 13 to be processed is quickly inserted, thereby improving the assembly efficiency of the tool 13 to be processed and thus greatly improving the production efficiency.

[0059] In some embodiments of this utility model, at least two sets of fixing blocks 6 are provided, and when two sets of fixing blocks 6 are provided, the two sets of fixing blocks 6 are symmetrically distributed; when at least three sets of fixing blocks 6 are provided, the at least three sets of fixing blocks 6 are distributed in a ring array.

[0061] Specifically, when there are two sets of fixing blocks 6, the two sets of fixing blocks 6 are symmetrically distributed, and the two sets of fixing blocks 6 can be respectively locked in the serrated grooves on both sides of the tool to be processed 13 to ensure the precise positioning of the tool to be processed 13.

[0062] In addition, when there are at least three sets of the fixing blocks 6, the at least three sets of the fixing blocks 6 are arranged in a circular array to ensure the precise positioning of the tool 13 to be processed and to ensure the processing accuracy.

[0063] In some embodiments of this utility model, a plurality of positioning bolts 11 are also included, which are used to connect the fixture base 2 and the fixture cover plate 3.

[0064] In some of the embodiments of this utility model described above, the fixture base 2 and the fixture cover plate 3 are locked together by positioning bolts 11, so that the tool to be processed 13 can be stably clamped between the two, ensuring the positioning accuracy of the tool to be processed 13 and improving the processing accuracy.

[0065] Specifically, four positioning bolts 11 are provided, and the four positioning bolts 11 are distributed in a rectangular structure.

[0066] Optionally, five positioning bolts 11 are provided, four of which are distributed in a rectangular structure, and the other positioning bolt 11 is located at the center of the rectangular structure.

[0067] In addition, the positioning bolts 11 are provided in several quantities, including three, six, seven, eight, etc.

[0068] In some embodiments of this utility model, the fixing block 6 is detachably mounted on one of the clamp base 2 and the clamp cover plate 3.

[0069] In some embodiments of the present invention described above, the fixing block 6 is detachably mounted on one of the fixture base 2 and the fixture cover plate 3. The fixing block 6 can be disassembled so that when the same set of fixture base 2 and fixture cover plate 3 are used, the fixing block 6 can also be replaced to achieve the processing of cutting edges of different sizes.

[0070] Specifically, a fixing hole is provided on the fixture base 2 or the fixture cover plate 3, the fixing hole is adapted to the fixing block 6, and the fixing block 6 is detachably installed in the fixing hole.

[0074] The hobbing cutter machining fixture mechanism provided by this utility model includes a fixture base 2 and a fixture cover plate 3. The fixture base 2 and the fixture cover plate 3 are connected by the positioning component described above. At the same time, the positioning component can simultaneously process the cutting edges of several cutting tools 13 to be processed, which greatly improves the processing efficiency and ensures high precision of the processed cutting edges, meeting high quality requirements. It avoids the problem of low cutting edge processing precision caused by using glue to bond several cutting tools 13 to be processed in the prior art. It also eliminates the need to clean residual glue after processing, simplifying the production process and significantly reducing costs and increasing efficiency.

[0075] In some embodiments of this utility model, the clamp base 2 is provided with a base platform that is inclined at a preset angle, and the clamp cover plate 3 is connected to the base platform.

[0076] In some embodiments of the present invention described above, the fixture base 2 is provided with a base platform, which is inclined at a preset angle. The inclination angle is consistent with the slope of the cutting edge, thereby ensuring that the cutting edge has the set slope after processing. The hobbing cutter processing fixture mechanism provided by the present invention also solves the problem that the cutting edge of the tool is inclined and difficult to process with a general grinding machine, and has wider applicability.

[0077] In some embodiments of this utility model, a workbench is also included, and the clamp base 2 is magnetically connected to the workbench.

[0078] In some of the embodiments of this utility model described above, the fixture base 2 is magnetically connected to the worktable, making the connection of the fixture base 2 more convenient, which can significantly reduce operation time, improve production efficiency, and avoid processing errors caused by loose screws.

[0079] It is understandable that the fixture base 2 and the worktable can also be fixed with screws, which can also ensure the clamping stability of the tool 13 to be processed.
