[0002] With increasing attention to environmental protection and sustainable energy, electric vehicles (EVs) have gained widespread attention and development as an alternative to traditional fuel vehicles. EVs require regular charging to maintain operation, making the development of charging infrastructure a key factor in their development. Charging plugs, the interface connecting EVs to charging equipment, must meet requirements such as high power transmission, safety, reliability, and durability. Copper alloys have excellent electrical, thermal, and mechanical properties, making them ideal materials for charging plug manufacturing. Currently, the manufacturing process for charging plugs involves machining copper alloy bars into finished structures using a Swiss-type machining center (CNC) machine, followed by surface electroplating. While charging plugs have similar appearances, they possess a wide variety of structural features. Conventional milling cutters are typically used to machine these structures. However, some of these structures are complex, including side holes, multi-stepped grooves, irregularly rounded outer diameters, and multiple columns or stepped grooves added to the end faces. Existing techniques utilize multiple saw blades with different outer diameters for machining, requiring frequent tool switching and consuming significant processing time. Furthermore, the step grooves are formed using multiple tools, which compromises precision. Therefore, the inventors have designed a combination saw blade tool for machining copper charging plugs for new energy vehicles to address these issues. Utility Model Content

The handle 11 includes a handle rod body 111 and a handle step column 112 fixedly connected to one end of the handle rod body 111. The diameter of the handle step column 112 is smaller than the diameter of the handle 11. The handle step column 112 is integrally formed with the handle 11. A first mounting hole 121 is opened at the center of the first saw blade blade 12. The first saw blade blade 12 is sleeved on the handle step column 112 through the first mounting hole 121. The second saw blade blade 13 is A second mounting hole 131 is provided at the center, and the second saw blade blade 13 is sleeved on the handle step column 112 through the second mounting hole 131 and is placed on one side of the first saw blade blade 12. A threaded hole is provided at one end of the handle step column 112, and a fastening screw 14 is connected in the threaded hole to fasten the first saw blade blade 12 and the second saw blade blade 13 to the handle 11. The outer diameter of the second saw blade blade 13 is smaller than the outer diameter of the first saw blade blade 12. The combined tool 1 composed of the first saw blade blade 12, the second saw blade blade 13, the handle 11 and the fastening screw 14 can realize the processing and forming of the step groove of the charging plug product at one time, thereby improving the processing efficiency, ensuring the processing size accuracy, meeting the processing requirements of special-shaped features, and having high practicality.

[0026] In this embodiment, the first saw blade blade 12 and the second saw blade blade 13 are made of one of high-speed steel and cemented carbide to ensure service life; the outer diameter of the first saw blade blade 12 and the second saw blade blade 13 is consistent with the slot width of the charging plug product, and the thickness of the first saw blade blade 12 and the second saw blade blade 13 is consistent with the slot depth of the charging plug product. The outer diameter and thickness of the first saw blade blade 12 and the second saw blade blade 13 can be designed according to the charging plug product to be processed to ensure that the step groove is processed and formed in one time, and the combination tool 1 has a simple structure and is easy to assemble.

[0027] In this embodiment, if Figure 3 、 Figure 4 and Figure 5As shown, a pair of limiting grooves 1121 are symmetrically opened on both sides of the handle step column 112, and the shapes of the first mounting hole 121 and the second mounting hole 131 are adapted to the shape of the handle step column 112. The handle step column 112 has the limiting grooves 1121 opened on both sides, so that the cross-section of the handle step column 112 forms a rectangular structure with two arc-shaped ends, so that when the first saw blade blade 12 and the second saw blade blade 13 are sleeved and installed on the handle step column 112, the first saw blade blade 12 and the second saw blade blade 13 are limited in the longitudinal direction to prevent the first saw blade blade 12 and the second saw blade blade 13 from rotating.

[0028] In this embodiment, if Figure 4 and Figure 6 As shown, a positioning structure is provided between the first saw blade blade 12 and the second saw blade blade 13, and the positioning structure includes a positioning block 132 fixedly connected to the side of the second saw blade blade 13 close to the first saw blade blade 12, and a plurality of positioning blocks 132 are provided along the circumferential direction of the second saw blade blade 13, and a positioning groove 122 for inserting the positioning block 132 is provided on the side of the first saw blade blade 12 close to the second saw blade blade 13. When the second saw blade blade 13 and the first saw blade blade 12 are assembled, the positioning block 132 is inserted into the positioning groove 122 to improve the connection stability between the second saw blade blade 13 and the first saw blade blade 12, and to ensure that the second saw blade blade 13 is installed in the correct position. In addition, the setting of the positioning block 132 and the positioning groove 122 plays a fool-proof effect, thereby preventing the second saw blade blade 13 from being installed upside down with the first saw blade blade 12, resulting in the misalignment of the blade directions of the second saw blade 13 and the first saw blade 12, affecting the processing effect.

[0029] In this embodiment, if Figure 6 As shown, the length of the positioning block 132 gradually decreases along the direction of the second saw blade blade 13 toward the first saw blade blade 12, and the shape of the positioning groove 122 is adapted to the shape of the positioning block 132. Through the shape setting of the positioning block 132, when the second saw blade blade 13 and the first saw blade blade 12 are assembled, the end of the positioning block 132 with a smaller length is inserted into the positioning groove 122 first, thereby improving the convenience of assembly.

The depth of the countersunk hole 133 is greater than the thickness of the end, so that the countersunk hole 133 can fully accommodate the end of the fastening screw 14, avoiding the end of the fastening screw 14 protruding and hindering the processing and use of the combination tool 1.

[0031] As an implementation method in this embodiment, the use of the first saw blade 12 and the second saw blade 13 as the saw blade blade component in the above embodiment is only one form of expression. The number of saw blades in the saw blade blade component can also be 3, 4, 5, etc., depending on the step groove of the processed charging plug product. It should be noted that the outer diameter size of the saw blade blade must decrease in sequence from the handle step column 112 to the handle rod body 111.

[0032] Working principle: During assembly, first install and sleeve the first saw blade blade 12 on the handle step column 112 of the handle 11, and then install and sleeve the second saw blade blade 13 on the handle step column 112 of the handle 11, and insert the positioning block 132 into the positioning groove 122, so that the second saw blade blade 13 is connected and assembled with the first saw blade blade 12. The handle step column 112 is a rectangular structure with two arc-shaped ends, and the shapes of the first mounting hole 121 and the second mounting hole 131 are adapted to the shape of the handle step column 112, so that the first saw blade blade 12 and the second saw blade blade 13 are longitudinally limited to prevent the first saw blade 12 from being engaged. The saw blade 12 and the second saw blade 13 rotate, and then the fastening screw 14 is connected to the threaded hole of the handle step column 112 to fasten the first saw blade 12 and the second saw blade 13 to the handle 11 to complete the assembly. The combined tool 1 composed of the first saw blade 12, the second saw blade 13, the handle 11 and the fastening screw 14, and the first saw blade 12 and the second saw blade 13 with different outer diameters can realize the processing and forming of the step groove of the charging plug product at one time, thereby improving the processing efficiency, ensuring the processing dimensional accuracy, meeting the processing requirements of special-shaped features, and having high practicality.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
