Description

Technical Field

[0001] This utility model relates to the field of chamfering machine technology, and in particular to a chamfering machine for processing SAE flanges. Background Technology

[0002] In the field of mechanical manufacturing, SAE flanges are important connecting components, and their processing quality directly affects the performance and reliability of the entire mechanical system. Chamfering is a key process in the processing of SAE flanges, and precise chamfering can effectively improve the assembly accuracy of the flanges.

[0003] Currently, when performing chamfering operations on SAE flanges, due to the differences in size and shape among different specifications of SAE flanges, the positioning device on the chamfering machine is difficult to adjust and adapt flexibly and quickly according to the flange specifications. When processing SAE flanges of different specifications, it is often necessary to replace the entire positioning fixture, which undoubtedly increases production costs and reduces actual processing efficiency. Therefore, to solve this problem, designing a chamfering machine for processing SAE flanges is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a chamfering machine for SAE flange processing. To address usability issues, it incorporates a positioning mechanism that allows for convenient positioning of the SAE flange before processing by controlling the movement of the clamping plate and cylindrical positioning block. It also includes a switching component that allows for easy and flexible replacement of the clamping plate and cylindrical positioning block according to the specifications of the SAE flange, making it highly practical.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chamfering machine for SAE flange processing includes a worktable with a chamfering device at its upper end; a positioning mechanism comprising a rectangular support block fixedly connected to the upper end of the worktable, a rectangular groove formed at the upper end of the rectangular support block, a motor mounted on the right side of the rectangular support block, and a bidirectional threaded rod rotatably connected between the inner walls of the left and right sides of the rectangular groove. Each threaded end of the bidirectional threaded rod is threadedly connected to a slider, and each slider is fixedly connected to a mounting block at its upper end. Each mounting block has a clamping plate on its opposite side. Multiple cylindrical positioning blocks are fixedly connected to the opposing sides of the plates; the switching assembly includes T-shaped inserts fixedly connected to the opposite sides of the two clamping plates respectively, T-shaped slots are opened at the upper ends of the two mounting blocks, rectangular inner grooves are opened on the inner walls of the two T-shaped slots, rectangular limiting blocks are provided in the two rectangular inner grooves, and first threaded rods are rotatably connected to the opposite sides of the two rectangular limiting blocks. The opposite ends of the two first threaded rods pass through the corresponding rectangular inner grooves and are fixedly connected to torsion blocks. The two first threaded rods are threadedly connected to the corresponding mounting blocks.

[0007] Preferably, the right end of the bidirectional threaded rod penetrates the right inner wall of the rectangular slide groove and is fixedly connected to the output shaft of the motor.

[0008] Preferably, a guide rod is fixedly connected between the inner walls of the left and right sides of the rectangular groove, and the guide rod passes through the two sliders and is slidably connected to the two sliders.

[0009] Preferably, both T-shaped inserts are slidably connected to the inner wall of the corresponding T-shaped slot.

[0010] Preferably, both rectangular limiting blocks are slidably connected to the inner wall of the corresponding rectangular inner groove.

[0011] Preferably, the lower ends of both rectangular limiting blocks are abutted against the upper ends of the corresponding T-shaped inserts.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A positioning mechanism is installed, which drives the bidirectional threaded rod to rotate by starting the motor, causing the two clamping plates and multiple cylindrical limit blocks on them to move towards each other, thus facilitating stable positioning of the SAE flange.

[0019] 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.

[0020] Reference Figures 1-4 A chamfering machine for processing SAE flanges includes a worktable 1, with a chamfering device 2 installed at the upper end of the worktable 1. This is existing technology. It is mainly composed of a frame, motor, spindle, transmission device, chamfering tool, control system and other components. By controlling the chamfering tool to cut or grind, the sharp angle of the flange workpiece edge is removed to form a smooth transition surface, which can efficiently realize the chamfering operation of SAE flanges.

[0021] The system also includes a positioning mechanism, which comprises a rectangular support block 3 fixedly connected to the upper end of the worktable 1. A rectangular slide groove 4 is formed at the upper end of the rectangular support block 3. A motor 5 is mounted on the right side of the rectangular support block 3; the motor 5 is a motor capable of changing its rotation direction. A bidirectional threaded rod 6 is rotatably connected between the inner walls of the left and right sides of the rectangular slide groove 4. The two threaded ends of the bidirectional threaded rod 6 have opposite thread directions. The right end of the bidirectional threaded rod 6 penetrates the right inner wall of the rectangular slide groove 4 and is fixedly connected to the output shaft of the motor 5. A slider 7 is threadedly connected to each of the two threaded ends of the bidirectional threaded rod 6. The rectangular slide groove 4... A guide rod 17 is fixedly connected between the inner walls of the left and right sides. The guide rod 17 passes through the two sliders 7 and is slidably connected to the two sliders 7. An installation block 8 is fixedly connected to the upper end of each of the two sliders 7. A clamping plate 9 is provided on the opposite side of each of the two installation blocks 8. Multiple cylindrical positioning blocks 10 are fixedly connected to the opposite side of each of the two clamping plates 9. By controlling the two clamping plates 9 to move towards each other until they are respectively in contact with the two sides of the SAE flange, and the multiple cylindrical positioning blocks 10 are inserted into the corresponding bolt holes on the SAE flange (the cylindrical positioning blocks 10 are in contact with the inner wall of the bolt holes), the SAE flange can be conveniently positioned.

[0022] The system also includes a switching assembly, which comprises T-shaped inserts 11 fixedly connected to the opposite sides of two clamping plates 9. Each of the two mounting blocks 8 has a T-shaped slot 12 at its upper end. Each T-shaped insert 11 is slidably connected to the inner wall of its corresponding T-shaped slot 12. Each T-shaped slot 12 has a rectangular inner groove 13 on its inner wall. Each rectangular inner groove 13 contains a rectangular limiting block 14, which is slidably connected to the inner wall of its corresponding rectangular inner groove 13. The lower ends of each rectangular limiting block 14 are abutted against the upper ends of its corresponding T-shaped insert 11. The T-shaped slot 12 can be used to limit the T-shaped plug 11. The opposite sides of the two rectangular limiting blocks 14 are rotatably connected to the first threaded rod 15. The opposite ends of the two first threaded rods 15 pass through the corresponding rectangular inner groove 13 and are fixedly connected to the torsion block 16. The two first threaded rods 15 are threadedly connected to the corresponding mounting block 8. By rotating the first threaded rod 15 to drive the rectangular limiting block 14 to move, the limiting of the T-shaped plug 11 can be controlled, so that the clamping plate 9 and multiple cylindrical positioning blocks 10 can be adapted to the specifications of the SAE flange.

[0023] In this utility model, during use, firstly, one side of the SAE flange is attached to the left side clamping plate 9, and multiple cylindrical positioning blocks 10 are inserted into the corresponding bolt holes on the flange. Then, the motor 5 is started to drive the bidirectional threaded rod 6 to rotate, which drives the two sliders 7, two mounting blocks 8, two clamping plates 9 and the multiple cylindrical positioning blocks 10 on them to move towards each other. When the two clamping plates 9 are attached to both sides of the SAE flange respectively, and the multiple cylindrical positioning blocks 10 fixedly connected to the two clamping plates 9 are inserted into the corresponding bolt holes on the SAE flange, the SAE flange can be stably positioned. The entire positioning process is relatively convenient, and the actual positioning workload is low. After the positioning operation is completed, the operator can start the chamfering device 2 and control the chamfering cutter on it to remove the sharp corners of the flange workpiece edge to complete the chamfering operation of the SAE flange. After the chamfering operation is completed, the two clamping plates 9 are controlled to move in opposite directions to remove the SAE flange.

[0024] It is worth mentioning that when processing SAE flanges of different specifications, the two clamping plates 9 and their multiple cylindrical positioning blocks 10 can be replaced according to the specifications of the SAE flange. First, replace the left clamping plate 9 and multiple cylindrical positioning blocks 10. Rotate the left torsion block 16 to drive the first threaded rod 15 to rotate, causing the rectangular limit block 14 to move completely into the rectangular inner groove 13, so that the lower end of the rectangular limit block 14 is no longer in contact with the upper end of the left T-shaped insert 11. At this time, the left T-shaped insert 11 can be removed from the T-shaped slot 12 to remove the clamping plate 9 and multiple cylindrical positioning blocks 10. Then, replace it with a clamping plate 9 and multiple cylindrical positioning blocks that meet the specifications. Block 10 (multiple cylindrical positioning blocks 10 on the clamping plate 9 can be adapted to be inserted into the threaded holes on the current SAE flange), insert the T-shaped insert 11 fixedly connected to the new clamping plate 9 into the T-shaped slot 12 on the left, and then rotate the left twist block 16 in the opposite direction so that the lower end of the rectangular limit block 14 is once again in contact with the upper end of the T-shaped insert 11. This completes the replacement of the clamping plate 9 and multiple cylindrical positioning blocks 10 on the left. Similarly, referring to the above operation, the clamping plate 9 and multiple cylindrical positioning blocks 10 on the right can be replaced. In this way, by conveniently replacing the clamping plate 9 and the cylindrical positioning blocks 10, the stable positioning of SAE flanges of different specifications can be met, which has good practicality.

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.
