Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-4 The image shows a double-ended tool holder for wheel hub machining.

[0025] Example 1: A double-ended tool holder includes a tool holder 100. The side wall of the tool holder 100 has an outwardly protruding protrusion 109. The end of the tool holder 100 has a first cutting edge 101, and the end of the protrusion 109 near the first cutting edge 101 has a second cutting edge 106. A first blade 200 is fixedly installed at the first cutting edge 101 of the tool holder 100 and is used for trimming the side wall of the wheel hub blank. A second blade 300 is fixedly installed at the second cutting edge 106 of the protrusion 109 and is used to remove burrs from the wheel hub blank rim. In this example, by providing a protrusion 109 on the side wall of the tool holder 100, and providing a first cutting edge 101 and a second cutting edge at the same end positions on the same side of the tool holder 100 and the protrusion 109, respectively... 106. Install the first cutting tool 200 and the second cutting tool 300 so that they can be integrated on the same tool holder 100. Both the first cutting tool 200 and the second cutting tool 300 are assembled to one side of the tool holder 100. This allows the tool holder 100 to use the first cutting tool 200 installed at the end position to cut and trim the side wall A of the wheel hub blank. Then, the second cutting tool 300 at the end position of the protrusion 109 is used to clean the burrs at the rim of the wheel hub blank. This allows the two machining processes on the wheel hub blank to be performed using the same tool holder 100 without the need for a complete replacement on the lathe, thereby reducing tool change time and making the side wall trimming and burr cleaning of the wheel hub blank more efficient.

[0026] Example 2, based on Example 1, further describes that a straight groove 102 extending into the tool holder 100 is provided on the inner wall of the first cutting edge 101 away from the first blade 200. The end of the straight groove 102 away from the first cutting edge 101 is cylindrical. A downwardly recessed polygonal groove 103 is provided on the bottom inner wall of the straight groove 102 near the end of the first cutting edge 101. A clamping assembly is provided on the end of the tool holder 100 near the first blade 200. The clamping assembly is used to drive the first cutting edge 101 to be clamped. By providing a straight groove 102 extending into the inside of the tool holder 100 on the inner wall of the first cutting edge 101, the first cutting edge of the tool holder 100 is... Position 101 can be opened to facilitate the installation of the first blade 200 at the first cutting edge 101. Simultaneously, the polygonal groove 103 allows the user to use a wrench, such as a hex wrench, inserted into the groove and rotated to lift the first cutting edge 101. This facilitates the insertion of the first blade 200's shaft into the first cutting edge 101. Furthermore, the clamping assembly limits and locks the end of the straight groove 102, preventing expansion. This ensures a stable clamping and fixing of the first blade 200 at the first cutting edge 101, making the installation and removal of the first blade 200 at the first cutting edge 101 more convenient.

[0027] Furthermore, the inner walls on both the upper and lower sides of the first cutting edge 101 gradually bulge towards the center along the two side edges, and the shank of the first blade 200 is adapted to the shape of the inner wall of the first cutting edge 101. It should be noted that the shape of the shank of the first blade 200 and the upper and lower sides of the first cutting edge 101 are mutually adapted. This design enables the first blade 200 to achieve automatic positioning after being inserted into the first cutting edge 101 when it is installed. This improves the accuracy of the installation of the first blade 200.

[0028] The clamping assembly includes a settling hole 104 and a clamping bolt 105. The settling hole 104 is located at the top end of the tool holder 100 and communicates with the straight groove 102. The clamping bolt 105 is movably connected to the inside of the settling hole 104, and the bottom of the clamping bolt 105 extends downward and is threadedly connected to an internal threaded hole at the bottom of the inner side of the straight groove 102. By inserting the clamping bolt 105 into the settling hole 104 and tightening it with the internal threaded hole at the bottom of the straight groove 102, the opening of the first cutting edge 101 can be limited, and the clamping force required for the first cutting edge 101 to hold the first blade 200 can be provided, ensuring that the first blade 200 is securely installed at the first cutting edge 101.

[0029] Example 3, based on Example 1 or Example 2, further describes that a circular groove 107 is provided at the end of the second cutting edge 106 away from the first cutting edge 101, and the end of the second blade 300 extends movably into the circular groove 107. A fastener for fixing the second blade 300 at the position of the second cutting edge 106 is provided between the second blade 300 and the second cutting edge 106. The circular groove 107 at the end of the second cutting edge 106, combined with the rhomboid shape of the second blade 300, achieves the positioning of the second blade 300 at the position of the second cutting edge 106, making the installation of the second blade 300 at the position of the second cutting edge 106 more accurate and convenient.

[0030] The fasteners include a screw hole 108 and a screw. The screw hole 108 is located at the bottom inner side of the second cutting edge 106. The screw passes through the through hole in the middle of the second blade 300 and is threaded into the screw hole 108. After the second blade 300 is positioned at the second cutting edge 106, simply pass the screw through the through hole on the second blade 300 and thread it into the screw hole 108 and tighten it to fix the second blade 300 at the second cutting edge 106. At the same time, the second blade 300 is detachable, making subsequent disassembly and maintenance of the second blade 300 more convenient.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
