[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model. Example

[0025] Reference Figure 1-3This utility model discloses a processing fixture for elbows, comprising: a base 1, with positioning blocks 2 fixedly connected to both the left and right sides of the upper surface of the base 1. The positioning blocks 2 provide a mounting base for components such as rotating blocks 4 and abutment posts 5, and cooperate with the base 1 to ensure the stability of the entire fixture structure, enabling accurate positioning and processing of elbows 3. A rotating groove 10 is provided inside the positioning block 2, and the interior of the rotating groove 10 is connected to the outer surface of the positioning block 2. The rotating groove 10 provides rotation space for the rotating block 4, allowing it to rotate flexibly within the positioning block 2 to adjust its position. The rotating block 4 is rotatably connected to the inner surface of the rotating groove 10, allowing it to rotate within the rotating groove 10. This rotation changes the position of the abutment posts 5, thereby achieving the desired positioning of the elbow 3. The adjustment is achieved by threading an adjusting bolt 9 onto the side wall of the rotating block 4. The adjusting bolt 9 engages with the rotating block 4, and rotating the adjusting bolt 9 allows the abutment post 5 to slide within the rotating block 4, thereby achieving precise adjustment of the position of the abutment post 5. The rear surface of the rotating block 4 is slidably connected to the abutment post 5, which extends to the front surface of the rotating block 4. The abutment post 5 can slide within the rotating block 4. When the abutment post 5 slides forward, it abuts against the elbow 3, thus positioning and fixing the elbow 3. The front surface of the abutment post 5 abuts against the elbow 3, and the abutment post 5 and the elbow 3 are in direct contact. The abutment force fixes the elbow 3 in a suitable position, facilitating subsequent processing. The base 1 has a mating groove 8 inside, and the mating groove 8 is located below the positioning block 2. The mating groove 8 engages with the positioning block 2. The components, such as the abutment column 5, cooperate with each other to provide suitable space and positional relationships, ensuring the overall coordination of the fixture. The rear surface of the positioning block 2 is threaded with a first positioning bolt 12, which extends into the interior of the positioning block 2. The first positioning bolt 12 engages with the positioning block 2; tightening the first positioning bolt 12 causes its front surface to abut against the inner wall of the rotating groove 10, thereby fixing the position of the rotating block 4. The front surface of the positioning block 2 is provided with a processing assembly, which includes a second positioning bolt 13, a processing tube 7, and a clamping block 6. The processing assembly is used to perform processing operations on the elbow 3, cooperating with the positioning block 2 to ensure the stability and accuracy of the processing. The clamping block 6 is fixedly connected to the positioning block 2 via the second positioning bolt 13. The second positioning bolt 13 and positioning block 2 cooperate to firmly install the tightening block 6 on the positioning block 2, enabling it to stably apply pressure to the elbow 3. A processing tube 7 is fixedly connected inside the tightening block 6. The processing tube 7 cooperates with the tightening block 6, and the fixing action of the tightening block 6 ensures the stability of the position of the processing tube 7, facilitating the processing of the elbow 3. The interior of the processing tube 7 is connected to the interior of the elbow 3, providing a channel for processing operations and allowing for smooth processing. The rear surface of the processing tube 7 extends into the interior of the elbow 3, allowing for more precise processing of the interior of the elbow 3. There are two positioning blocks 2, and a mating groove 8 is located between the two positioning blocks 2, fitting perfectly to each other.Two positioning blocks 2 cooperate to position and fix the elbow 3 from both sides. The fit between the mating groove 8 and the positioning block 2 ensures the rationality and stability of the entire fixture structure. The size of the abutment post 5 matches the size of the mating groove 8. This fit allows the abutment post 5 to accurately enter the mating groove 8 during sliding, ensuring accurate positioning of the elbow 3. The adjusting bolt 9 abuts against the outer surface of the abutment post 5. The adjusting bolt 9 cooperates with the abutment post 5, and the rotation of the adjusting bolt 9 pushes the abutment post 5 to move, achieving fine adjustment of the elbow 3's position. The front surface of the first positioning bolt 12 abuts against the inner wall of the rotating groove 10. The first positioning bolt 12 cooperates with the rotating groove 10, fixing the position of the rotating block 4 within the rotating groove 10 through the abutment action, preventing the rotating block 4 from rotating arbitrarily. Example

[0026] Reference Figure 4-6 The difference from Embodiment 1 is that the processing component includes: a clamping block 11 and a second positioning bolt 13. The size of the mating groove 8 is adapted to the clamping block 11. The mating relationship between the mating groove 8 and the clamping block 11 allows the clamping block 11 to slide flexibly within the mating groove 8, facilitating the clamping operation of the elbow 3. The clamping block 11 is located between the positioning blocks 2, which facilitates the positioning of the clamping block 11 and allows it to flexibly abut against the elbow 3. The inner surfaces of the clamping block 11 and the mating groove 8 are slidably connected. The clamping block 11 and the mating groove 8 cooperate, and by sliding within the mating groove 8, the elbow 3 can be clamped and released, facilitating the processing operation.

[0027] Working principle: With the processing tube 7 and the clamping block 6 in working condition, first place the elbow 3 in a suitable position on the base 1. Adjust the angle and position of the abutment column 5 by rotating the rotating block 4 so that its front surface abuts the elbow 3. Then rotate the adjusting bolt 9 so that it abuts the abutment column 5. Fine-tune the abutment force of the abutment column 5 against the elbow 3 to achieve the initial positioning of the elbow 3. Operate the clamping block 6 so that its rear surface abuts the elbow 3 tightly. Then use the second positioning bolt 13 to fix the clamping block 6 on the positioning block 2 to further stabilize the elbow 3. Next, push the processing tube 7 so that its rear surface extends into the interior of the elbow 3 to ensure that the interior of the processing tube 7 is connected to the interior of the elbow 3, preparing for the subsequent processing operation of the elbow 3.

[0028] With the clamping block 11 in operation, first place the elbow 3 on the base 1, rotate the rotating block 4 to move the abutment column 5 and abut the elbow 3, rotate the adjusting bolt 9 to fine-tune the abutment column 5, and initially fix the position of the elbow 3. Slide the clamping block 11 in the mating groove 8 to a suitable position so that the clamping block 11 fits against the elbow 3. Then use the second positioning bolt 13 to fix the clamping block 11 on the positioning block 2. By using the cooperation between the clamping block 11 and the positioning block 2, the elbow 3 is clamped for subsequent processing.
