Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example: This example provides a chamfering tool adjustment fixture for machining a differential housing. See [link to example]. Figure 1-6Specifically, including:

[0031] The system comprises a workpiece housing 1, a rotating block 2, and a tool body 201. The tool body 201 is bolted to the rotating block 2. An adjusting shaft 3 is rotatably connected to the workpiece housing 1, and the rotating block 2 is fixedly mounted on the outer wall of the adjusting shaft 3. A rotating plate 301 is fixedly mounted on the other end of the adjusting shaft 3. In use, the user rotates the adjusting shaft 3 to drive the rotating block 2 to rotate, which in turn drives the tool body 201 to rotate, allowing adjustment of the application angle of the tool body 201. This facilitates adjustment of the chamfering requirements according to the shape, structure, and different parts of the differential housing, adapting to the processing requirements of different parts, ensuring accurate contact between the tool tip and the workpiece, thereby improving processing accuracy, reducing errors, reducing tool change frequency, lowering tool costs, and improving processing efficiency. The rotating plate 301 is equipped with a positioning unit, which includes:

[0032] The positioning block 303 and the outer wall of the rotating plate 301 are provided with a groove, and a compression spring 304 is fixedly installed on the inner wall of the groove on the outer wall of the rotating plate 301. The other end of the compression spring 304 is fixedly connected to the positioning block 303.

[0033] A fixing ring 4 is fixedly mounted on the outer wall of the workpiece housing 1. The outer wall of the fixing ring 4 has a positioning port 401. The positioning block 303 is mated and locked in the corresponding positioning port 401. In use, when the tool body 201 rotates to the corresponding position, the rotation of the adjusting shaft 3 is stopped. At this time, the positioning block 303 is aligned with the positioning port 401 at the corresponding position. The positioning block 303 is pushed outward by the pushing force of the compression spring 304, so that the positioning block 303 is inserted into and locked in the positioning port 401, thereby fixing the position of the rotating plate 301, thus fixing the use position of the tool body 201 and ensuring the normal use of the tool body 201.

[0034] The outer wall of the rotating plate 301 is provided with a connecting groove 302, and the outer wall of the positioning block 303 is fixedly provided with a connecting rod 305. One end of the connecting rod 305 extends outward through the connecting groove 302 and is fixedly provided with an adjusting block 306. The connecting rod 305 slides in the connecting groove 302, thereby limiting the movement range of the positioning block 303 and extending the action point of the positioning block 303 for easy adjustment by the user.

[0035] The outer wall of the rotating plate 301 is rotatably connected to a rotating rod 6 via a pin, and the rotating rod 6 is movably inserted between two sets of adjusting blocks 306. By rotating the rotating rod 6, the two ends of the rotating rod 6 are brought close to the adjusting blocks 306, thereby restricting the position of the two sets of adjusting blocks 306 and preventing the adjusting blocks 306 from moving arbitrarily and affecting the positioning of the positioning block 303.

[0036] The outer wall of the adjusting block 306 is provided with a sliding groove 307, and a retaining plate 5 is movably inserted into the inner wall of the sliding groove 307 to restrict the position of the rotating rod 6. In use, the user pushes the retaining plate 5 into the inner cavity of the sliding groove 307 so that the retaining plate 5 is inserted into the sliding groove 307. At this time, the rotating rod 6 is rotated so that the adjusting block 306 has a certain amount of room to move. The user pulls the adjusting block 306 towards the center point of the rotating plate 301, which causes the positioning block 303 to move and disengage from the positioning port 401, making it easier to adjust the rotating plate 301 later.

[0037] The outer wall of the card plate 5 is fixedly provided with a movable block 501, and two sets of movable blocks 501 are movably engaged in the slide groove 307. The movement range of the card plate 5 is limited by the two sets of movable blocks 501 restricting its movement within the slide groove 307.

[0038] A spring strip 502 is fixedly installed in the inner cavity of the slide groove 307, and the other end of the spring strip 502 is fixedly connected to the moving block 501. The moving block 501 is pushed by the pushing force of the spring strip 502, so that the moving block 501 drives the clamping plate 5 to move outward of the adjusting block 306, thereby restricting the position of the rotating rod 6.

[0039] The positioning port 401 is set in multiple sets, corresponding to different angles of the application of the blade body 201.

[0040] A silicone pad is fixedly adhered to the outer wall of the adjusting block 306 to increase the friction between the outer wall of the adjusting block 306 and the user's hand, making adjustment easier.

[0041] Specifically, the working principle and operation method of this utility model are as follows:

[0042] In use, the user presses the two sets of adjusting blocks 306 with their fingers, causing them to move towards the center point of the rotating plate 301. This movement of the adjusting blocks 306 drives the two sets of connecting rods 305, which in turn move the two sets of positioning blocks 303, causing them to move out of the positioning port 401. Then, rotating the rotating plate 301 causes the adjusting shaft 3 to rotate, which in turn drives the rotating block 2 to rotate, causing the tool body 201 to rotate. This allows for adjustment of the tool body 201's operating angle, facilitating chamfer adjustments based on the differential housing's shape, structure, and different parts. This adapts to various processing requirements, ensuring accurate contact between the tool tip and the workpiece, improving processing precision, reducing errors, and minimizing tool replacement frequency, thus lowering tool costs and increasing processing efficiency. After the tool body 201 reaches the corresponding position, the rotating plate 301 stops rotating. At this point, the positioning blocks 306... 3. Align with the corresponding positioning port 401. Multiple sets of positioning ports 401 are provided, corresponding to different angles of the blade body 201 application. By releasing the pressed adjustment block 306, the pushing force of the compression spring 304 pushes the positioning block 303 outward, causing it to insert and lock into the positioning port 401. This fixes the position of the rotating plate 301, thereby fixing the usage position of the blade body 201 and ensuring stable use. The user pushes the locking plate 5 into the inner cavity of the slide groove 307, causing it to retract into the slide groove 307. At this time, rotating the rotating rod 6 brings both ends of the rotating rod 6 close to the two sets of adjustment blocks 306, restricting the position of the two sets of adjustment blocks 306. This helps prevent the adjustment blocks 306 from moving arbitrarily and affecting the positioning of the positioning block 303. Furthermore, the pushing force of the spring bar 502 pushes the moving block 501, causing the moving block 501 to move the locking plate 5 outward from the adjustment block 306, further restricting the position of the rotating rod 6 and improving stability.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
