Technical Field

[0001] This invention relates to the field of pipe fitting processing and positioning tooling technology, and in particular to a multi-cut positioning tool for thin-walled irregular pipe fittings. Background Technology

[0002] The multi-cut positioning fixture for thin-walled special-shaped pipe fittings is a production equipment used to process the main shape of the opening of small-sized thin-walled special-shaped pipe fittings, and plays an important role in ensuring the processing quality of small-sized tapered pipe fittings.

[0003] Currently, cutting positioning fixtures can only perform single-piece cutting, which is inefficient and has poor tooling consistency, affecting workpiece production efficiency and processing quality to some extent. In order to improve production efficiency and processing quality, in addition, single-piece cutting requires frequent clamping and disassembly of workpieces, which increases auxiliary time and reduces production efficiency. As the manufacturing industry continues to increase its requirements for product quality and production efficiency, traditional cutting positioning fixtures can no longer meet production needs. There is an urgent need for a positioning device that can cut multiple workpieces simultaneously and ensure processing consistency. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4 This invention discloses a multi-cut positioning tool for thin-walled irregular-shaped pipe fittings, comprising: L-shaped positioning block 1 has positioning and mounting holes on its surface. The L-shaped positioning block 1 is installed on the machine tool worktable by bolts through the positioning and mounting holes. The machine tool worktable has corresponding holes, and the number and position of the positioning holes can be adjusted according to the holes on the machine tool worktable to adapt to the installation of different machine tool worktables.

[0021] The base plate 2 is attached to the recess of the L-shaped positioning block 1, and two parallel T-shaped grooves are opened on the surface of the base plate 2. The base plate 2 serves as the foundation of the entire positioning fixture, providing stable support and realizing the function of quick tooling change. At the same time, the base plate 2 achieves bidirectional limiting through its own weight and the L-shaped positioning block 1.

[0022] The positioning block 3 has two integrally formed T-shaped bosses at its bottom. The positioning block 3 is installed on the end of the sliding groove on the surface of the base plate 2 through the two T-shaped bosses. The T-shaped bosses are adapted to the T-shaped sliding groove on the surface of the base plate 2. The positioning block 3 is fastened with flat-head screws to ensure the stability of the positioning block 3 after installation. At the same time, the surface of the positioning block 3 facing the L-shaped positioning block 1 has an installation groove.

[0023] Support block 4 has two integrally formed T-shaped protrusions at its bottom. Support block 4 is slidably mounted on the surface groove of base plate 2 via the T-shaped protrusions. The T-shaped protrusions are adapted to the T-shaped groove on the surface of base plate 2, thereby ensuring that support block 4 can only slide horizontally along the setting direction of the groove. At the same time, support block 4 is located between L-shaped positioning block 1 and positioning block 3, thereby limiting the movement stroke of support block 4 through L-shaped positioning block 1 and positioning block 3. The support block 4 has a first groove and a second groove on its side wall, with five of each groove. The five first grooves and five second grooves are vertically equidistant, and the second grooves in each layer are connected to the first grooves. The top of the support block 4 has a vertical hole that passes through the second groove. The pipe passes through the first groove, allowing the support block 4 to support the pipe and thus maintain the workpiece in a horizontal state during processing.

[0024] The pressure plate 5 has a through hole on its surface that matches the outer diameter of the connecting column 6. The pressure plate 5 is inserted into the second groove of the support block 4. When the pressure plate 5 is inserted into the second groove, the through hole is coaxially aligned with the vertical hole at the top of the support block 4. At the same time, the thickness of the pressure plate 5 corresponds to the thickness of the second groove.

[0025] The connecting post 6 is inserted into the vertical hole at the top of the support block 4 and passes through the pressure plate 5 to limit the position of the pressure plate 5. At the same time, the thickness of the pressure plate 5 corresponds to the thickness of the second groove, so that the pressure plate 5 can only rotate around the connecting post 6. Through the connection between the first groove and the second groove, the pressure plate 5 can rotate into the first groove to hold the workpiece and ensure the stability of the workpiece during the processing.

[0026] Multiple positioning blocks 7 are provided, which are at the same height and aligned with the support block 4. The multiple positioning blocks 7 are installed on the base plate 2 by bolts and pins. The multiple positioning blocks 7 have vertical threaded holes and two positioning grooves on their bottom surface. The top surface of the base plate 2 has threaded grooves corresponding to the threaded holes on the multiple positioning blocks 7 and positioning grooves corresponding to the two positioning grooves. Bolts are screwed into the threaded holes and threaded grooves, and pins are embedded in the positioning grooves and positioning grooves. The bolts and pins are used to achieve the limiting and fastening after installation. The surface of the multiple positioning blocks 7 is provided with notches, and five sets of insertion holes are vertically and equidistantly arranged on both sides of the notches of the multiple positioning blocks 7. The insertion holes are conical holes, and the central axis of the insertion holes intersects the central plane of the first groove on the surface of the support block 4 at the same horizontal plane. The insertion holes are used for the insertion of the conical surface of the workpiece, thereby achieving positioning.

[0027] Magnet 8 is interference-fitted into the mounting groove on the surface of positioning block 3, thereby enhancing the stability of the workpiece during processing.

[0028] Through the above structural settings: In use, first, the openings of multiple small-sized thin-walled irregular pipe fittings are placed into the insertion holes of multiple positioning blocks 7, and the conical surface of the workpiece is used for positioning. The tail of the pipe fitting is placed in the first groove of the support block 4. The pressure plate 5 is moved to hold the workpiece in place, ensuring the stability of the workpiece during processing. The support block 4 is secured by the magnet 8 to ensure that the pipe fitting is in a stable and pressed state during processing, ensuring that the pipe fitting will not shift during processing. After the pipe fitting is processed, the support block 4 is manually moved away from the magnet 8 by sliding, the pressure plate 5 is released, the workpiece is removed, the processing quality is checked, the positioning tool is cleaned, and the next workpiece is loaded.

[0029] The design of this positioning fixture achieved the following effects: 1. The device enables batch and efficient processing of small-sized, thin-walled, irregularly shaped pipe fittings at their openings; 2. Capable of achieving stable processing at the mouth; 3. The multi-layer design allows for the simultaneous positioning of multiple pipe fittings, enabling the simultaneous cutting of multiple workpieces and greatly improving production efficiency. 4. The precise positioning structure ensures the positional accuracy and dimensional consistency of the pipe fitting cuts, effectively improving processing quality; 5. The structure is compact and easy to operate, which reduces the number of equipment required and lowers production costs.
