Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to positioning fixtures for flange processing. Background Technology

[0002] Flange machining positioning fixtures are auxiliary tools used during machining to ensure that the flange is accurately fixed on the machine tool so as to perform various machining operations.

[0003] Chinese Patent Publication No. CN216542827U, published on 20220517, discloses a positioning fixture for flange processing, including a base. A left support is fixedly connected to the left side of the top of the base, and a right support is fixedly connected to the right side of the top of the base. A servo motor is fixedly connected to the top of both the left and right supports. The drive end of the servo motor passes through the top of the left and right supports respectively and is fixedly connected to a screw. An installation groove is provided on the inner side of both the left and right supports. The bottom end of the screw is rotatably connected to the bottom end of the installation groove. A moving block is slidably connected to the top of the inner side of each installation groove, and a horizontal plate is fixedly connected to the inner side of each moving block.

[0004] Existing flange processing positioning fixtures, such as those described above, place the flange into a positioning groove on the base. A servo motor rotates a screw, which in turn moves a pressure block to fix the flange. However, in practice, the positioning groove can only be designed to a fixed size, resulting in poor adaptability of the positioning fixture to flanges of different sizes. Therefore, there is an urgent need to propose corresponding positioning fixtures for flange processing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for flange processing in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning fixture for flange processing includes a base, an integrated support, a positioning plate detachably connected to the top of the support, a limiting groove in the middle of the positioning plate, the limiting groove including a rectangular segment and a triangular segment, and a positioning strip and a pushing component for pushing the positioning strip are integrated inside the middle of the positioning plate.

[0008] Preferably, the inner wall of the base is rotatably connected to the outer wall of the support via a bearing, and the front end face of the base is integrated with a limiting part for axial positioning of the support.

[0009] Preferably, the limiting part includes a positioning rod that is screwed to the front end face of the base, and the open end of the positioning rod abuts against the outer wall of the arc-shaped end of the support.

[0010] Preferably, the pushing component includes a push rod that is screwed into the inner wall of the positioning disk, the open end of the push rod being rotatably connected to the outer wall of the positioning strip, and the outer wall of the positioning strip being slidably connected to the inner wall of the positioning disk through a slot.

[0011] Preferably, a rubber pad is fixedly connected to the side of the positioning strip away from the push rod.

[0012] Preferably, a side plate is fixedly connected to the outer wall of the positioning disk, and the side plate is fixedly connected to the outer wall of the support via a locking rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the flange assembly is placed on top of the support, and the flange assembly is moved to abut against the two sets of inclined edges of the limiting groove. Then, the push rod is rotated to screw it into the inner surface wall of the positioning plate, and the open end of the push rod screws into the outer surface wall of the positioning strip, thereby providing a pushing force for the positioning strip. The positioning strip slides along the slot until it abuts against the outer surface wall of the flange assembly. The positioning strip, together with the limiting groove, completes the fixing of the flange assembly, ensuring the stable positioning of the flange assembly. At the same time, it can adapt to flange assemblies of different sizes, thereby improving the application range of positioning fixtures for flange processing.

[0015] 2. In this application, after the flange assembly is fixed, the positioning plate is moved to make it move in conjunction with the support. The support rotates with the inner wall of the base through the bearing until the positioning plate and the flange assembly are deflected to a suitable angle. Then, the positioning rod is rotated to screw it into the inner wall of the base. The axial positioning of the support and the flange assembly is achieved by the contact friction between the open end of the positioning rod and the outer wall of the support. This allows for axial adjustment of the flange assembly according to the processing needs of the subsequent operators, thereby improving the convenience of using the positioning fixture for flange processing.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A positioning fixture for flange processing includes a base 1, a support 6 integrated inside the base 1, a positioning plate 2 detachably connected to the top of the support 6, a limiting groove 3 in the middle of the positioning plate 2, the limiting groove 3 including a rectangular segment and a triangular segment, and a positioning strip 4 and a pushing component for pushing the positioning strip 4 are integrated inside the middle of the positioning plate 2.

[0025] Place the flange assembly on top of the support 6 and move the flange assembly to abut against the two sets of inclined edges of the limiting groove 3. Then rotate the push rod 5 to screw it into the inner surface of the positioning plate 2. The open end of the push rod 5 screws into the outer surface of the positioning strip 4, thereby providing a pushing force to the positioning strip 4. The positioning strip 4 slides along the slot 11 until it abuts against the outer surface of the flange assembly. The positioning strip 4, together with the limiting groove 3, completes the fixing of the flange assembly, ensuring the stable positioning of the flange assembly. At the same time, it can adapt to flange assemblies of different sizes, thereby improving the application range of positioning fixtures for flange processing.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the inner wall of the base 1 is rotatably connected to the outer wall of the support 6 via a bearing 10. The front end face of the base 1 integrates a limiting part for axial positioning of the support 6. The limiting part includes a positioning rod 9 that is screwed into the front end face of the base 1. The open end of the positioning rod 9 abuts against the outer wall of the arc-shaped end of the support 6. After the flange assembly is fixed, the positioning plate 2 is moved to link the support 6. The support 6 is rotatably engaged with the inner wall of the base 1 via the bearing 10 until the positioning plate 2 and the flange assembly are deflected to a suitable angle. Then, the positioning rod 9 is rotated to screw into the inner wall of the base 1. The axial positioning of the support 6 and the flange assembly is achieved through the contact friction between the open end of the positioning rod 9 and the outer wall of the support 6. This allows for axial adjustment of the flange assembly according to the processing needs of the subsequent operators, thereby improving the convenience of using the positioning fixture for flange processing.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the pushing assembly includes a push rod 5 that is screwed onto the inner wall of the positioning disk 2. The open end of the push rod 5 is rotatably connected to the outer wall of the positioning strip 4. The outer wall of the positioning strip 4 is slidably connected to the inner wall of the positioning disk 2 through a slot 11. Rotating the push rod 5 screws it onto the inner wall of the positioning disk 2, and the open end of the push rod 5 screws onto the outer wall of the positioning strip 4, thereby providing a pushing force to the positioning strip 4. The positioning strip 4 slides along the slot 11 until it abuts against the outer wall of the flange assembly. A rubber pad is fixedly connected to the side of the positioning strip 4 away from the push rod 5 to ensure stable contact between the positioning strip 4 and the flange assembly. A side piece 7 is fixedly connected to the outer wall of the positioning disk 2. The side piece 7 is fixedly connected to the outer wall of the support 6 through a locking rod 8, thereby ensuring the ease of disassembly and assembly of the positioning disk 2 and the support 6.

[0028] Working principle: Place the flange assembly on top of the support 6 and move the flange assembly to abut against the two sets of inclined edges of the limiting groove 3. Then, rotate the push rod 5 to screw it onto the inner surface of the positioning plate 2. The open end of the push rod 5 screws onto the outer surface of the positioning strip 4, thus providing a pushing force to the positioning strip 4. The positioning strip 4 slides along the slot 11 until it abuts against the outer surface of the flange assembly. The positioning strip 4, in conjunction with the limiting groove 3, completes the fixing of the flange assembly, ensuring the stable positioning of the flange assembly. This also allows for the adaptation to flange assemblies of different sizes, thereby improving the efficiency of flange processing. The positioning fixture is used in the following ways: After the flange assembly is fixed, the positioning plate 2 is moved to make it move the support 6. The support 6 rotates with the inner wall of the base 1 through the bearing 10 until the positioning plate 2 and the flange assembly are deflected to a suitable angle. Then, the positioning rod 9 is rotated to screw it into the inner wall of the base 1. The axial positioning of the support 6 and the flange assembly is achieved by the contact friction between the open end of the positioning rod 9 and the outer wall of the support 6. This allows for axial adjustment of the flange assembly according to the processing needs of the subsequent operators, thereby improving the convenience of using the positioning fixture for flange processing.
