Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting tooth processing technology, and in particular to a multi-angle positioning fixture for cutting tooth processing. Background Technology
[0002] Cutting teeth are the core cutting components of mining equipment such as coal mining machines and tunneling machines. Parameters such as the cutting edge angle and the welding angle of the carbide cutting tip directly affect the cutting efficiency, wear resistance and service life.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When using existing cutting tooth machining positioning fixtures, the angle needs to be adjusted frequently. However, when adjusting the angle, the workers usually use the method of manually moving the positioning fixture to make the adjustment, which is not only time-consuming and labor-intensive, but also increases the labor intensity of the workers and reduces work efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing positioning fixtures for cutting teeth need to be adjusted frequently during use. Workers usually have to manually move the positioning fixture to adjust it, which is time-consuming, labor-intensive, and reduces work efficiency. Therefore, we propose a multi-angle positioning fixture for cutting teeth.
[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-angle positioning fixture for cutting teeth, comprising a base: a sleeve is fixedly connected to the top of the base, a sleeve rod is rotatably connected inside the sleeve, a connecting plate is fixedly connected to the top of the sleeve rod, a positioning fixture is fixedly connected to the top of the connecting plate, multiple insertion slots are provided on the top of the base, an extension plate is fixedly connected to the surface of the sleeve rod, a through slot is provided on the top of the extension plate, an insertion rod is slidably connected inside the through slot, and an adjusting block is fixedly connected to the top of the insertion rod.
[0006] Preferably, a friction-enhancing sleeve is fixedly connected to the bottom surface of the plug rod, and the surface of the friction-enhancing sleeve is slidably connected to the inside of the plug groove.
[0007] Preferably, a return spring is fixedly connected to the bottom of the adjusting block, and the bottom of the return spring is fixedly connected to the top of the extension plate.
[0008] Preferably, the external shape of the friction-enhancing sleeve matches the internal shape of the insertion groove.
[0009] Preferably, the sleeve has a circular limiting groove inside, and a circular limiting block is fixedly connected to the surface of the sleeve rod, with the surface of the circular limiting block slidingly connected to the inside of the circular limiting groove.
[0010] Preferably, the surface of the circular limiting block is provided with a groove, and a roller is rotatably connected to the internal shaft of the groove, and the number of rollers is multiple.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] In this invention, the operator rotates the positioning fixture, causing the connecting plate to rotate. The connecting plate then rotates the sleeve rod inside the sleeve. Once the position of the positioning fixture is determined, the adjusting block can be moved so that the adjusting block's insertion rod passes through the through slot and inserts into the corresponding insertion groove, thus fixing the position of the positioning fixture. This allows the angle of the positioning fixture to be adjusted without the operator having to manually move it, reducing the operator's labor intensity and improving work efficiency.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.
[0020] Reference Figure 1 - Figure 3As shown, this utility model provides a technical solution: a multi-angle positioning fixture for cutting teeth, including a base 1; a sleeve 2 is fixedly connected to the top of the base 1, a sleeve rod 3 is rotatably connected inside the sleeve 2, a connecting plate 4 is fixedly connected to the top of the sleeve rod 3, a positioning clamp 5 is fixedly connected to the top of the connecting plate 4, multiple insertion slots 6 are provided on the top of the base 1, an extension plate 7 is fixedly connected to the surface of the sleeve rod 3, a through slot 8 is provided on the top of the extension plate 7, an insertion rod 9 is slidably connected inside the through slot 8, and an adjusting block 10 is fixedly connected to the top of the insertion rod 9. The operator rotates the positioning clamp 5, causing the positioning clamp 5 to drive the connecting plate 4 to rotate, and the connecting plate 4 to drive the sleeve rod 3 to rotate inside the sleeve 2. When the position of the positioning clamp 5 is determined, the adjusting block 10 can be moved so that the insertion rod 9 of the adjusting block 10 passes through the through slot 8 and inserts into the corresponding insertion slot 6, thereby fixing the position of the positioning clamp 5. This allows the angle of the positioning clamp 5 to be adjusted without the operator having to manually move the positioning clamp 5, reducing the labor intensity of the operator and improving work efficiency.
[0021] Reference Figure 3 As shown in this embodiment: a friction-enhancing sleeve 12 is fixedly connected to the bottom surface of the plug rod 9. The surface of the friction-enhancing sleeve 12 is slidably connected to the inside of the plug groove 6. By setting the friction-enhancing sleeve 12, the friction between the plug rod 9 and the plug groove 6 is increased, which improves the stability of the connection of the plug rod 9 inside the plug groove 6 and avoids the phenomenon of the plug rod 9 sliding inside the plug groove 6, thereby ensuring the stability of the positioning fixture 5 and improving the practicality of the multi-angle positioning fixture.
[0022] Reference Figure 3 As shown in this embodiment: a return spring 11 is fixedly connected to the bottom of the adjusting block 10. The bottom of the return spring 11 is fixedly connected to the top of the extension plate 7. By setting the return spring 11, when the plug rod 9 is plugged in, the return spring 11 provides a return force to the adjusting block 10, so that the adjusting block 10 and the extension plate 7 maintain a certain elastic connection, which makes it easy for the operator to pull the adjusting block 10 when the angle of the positioning clamp 5 needs to be adjusted.
[0023] Reference Figure 2 and Figure 3 As shown in this embodiment, the external shape of the friction-enhancing sleeve 12 matches the internal shape of the insertion groove 6. By setting the external shape of the friction-enhancing sleeve 12 to match the internal shape of the insertion groove 6, the connection tightness between the insertion rod 9 and the insertion groove 6 is further enhanced, reducing the shaking or loosening problems caused by shape mismatch. This not only improves the stability of the positioning fixture 5 in the multi-angle positioning tooling, but also ensures the high-precision positioning of the cutting teeth during the processing, thereby improving the processing efficiency.
[0024] Reference Figure 2 and Figure 4 As shown in this embodiment: a circular limiting groove 13 is provided inside the sleeve 2, and a circular limiting block 14 is fixedly connected to the surface of the sleeve rod 3. The surface of the circular limiting block 14 is slidably connected to the inside of the circular limiting groove 13. By setting the sliding connection structure between the circular limiting groove 13 and the circular limiting block 14, the rotational freedom of the sleeve rod 3 inside the sleeve 2 is effectively restricted, so that the sleeve rod 3 can only move along the axial direction of the sleeve 2. This not only enhances the stability of the tooling structure, but also ensures the accuracy of the sleeve rod 3 when driving the positioning fixture 5 to move, and avoids positioning errors caused by rotation.
[0025] Reference Figure 4 As shown in this embodiment: the surface of the circular limiting block 14 is provided with a groove 15, and the inner shaft of the groove 15 is rotatably connected to a roller 16. There are multiple rollers 16. By setting the rollers 16 rotatably connected to the inner shaft of the groove 15, and the number of rollers 16 is multiple, the frictional resistance when the circular limiting block 14 slides in the circular limiting groove 13 is effectively reduced, so that the sleeve 3 moves more smoothly along the axial direction of the sleeve 2. This not only improves the flexibility of the tooling structure, but also extends the service life of the tooling.
[0026] Working principle: By rotating the positioning clamp 5, the operator causes the connecting plate 4 to rotate, which in turn causes the sleeve rod 3 to rotate inside the sleeve 2. Once the position of the positioning clamp 5 is determined, the adjusting block 10 can be moved to allow the connecting rod 9 of the adjusting block 10 to pass through the through slot 8 and insert into the corresponding insertion slot 6, thus fixing the position of the positioning clamp 5. This allows for adjustment of the angle of the positioning clamp 5 without the need for manual movement, reducing the operator's workload and improving work efficiency. The friction-enhancing sleeve 12 increases the friction between the connecting rod 9 and the insertion slot 6, improving the stability of the connection within the insertion slot 6 and preventing slippage. This ensures the stability of the positioning clamp 5 and enhances the practicality of the multi-angle positioning fixture. A return spring 11 provides a restoring force to the adjusting block 10 after the connecting rod 9 is inserted, maintaining a certain elastic connection between the adjusting block 10 and the extension plate 7. This facilitates easy adjustment of the angle of the positioning clamp 5 by the operator. By loosening the adjusting block 10, the external shape of the friction-enhancing sleeve 12 matches the internal shape of the insertion groove 6, further enhancing the connection tightness between the insertion rod 9 and the insertion groove 6. This reduces the shaking or loosening problems caused by shape mismatch, improving the stability of the positioning fixture 5 in multi-angle positioning tooling and ensuring high-precision positioning of the cutting teeth during processing, thereby improving processing efficiency. By setting the sliding connection structure of the circular limiting groove 13 and the circular limiting block 14, the rotational freedom of the sleeve rod 3 inside the sleeve 2 is effectively restricted. This allows the sleeve rod 3 to move only along the axial direction of the sleeve 2, which not only enhances the stability of the tooling structure but also ensures the accuracy of the sleeve rod 3 when moving the positioning fixture 5, avoiding positioning errors caused by rotation. By setting multiple rollers 16 connected to the rotating shaft inside the slot 15, the frictional resistance of the circular limit block 14 when sliding inside the circular limit groove 13 is effectively reduced, making the sleeve rod 3 move more smoothly along the axial direction of the sleeve 2. This not only improves the flexibility of the tooling structure but also extends the service life of the tooling.
[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
