Description

Technical Field

[0001] This invention relates to the field of flange forging table technology, specifically a self-clamping and repositioning machine tool spindle flange forging table and its repositioning method. Background Technology

[0002] With the development of industrial automation, flange forging equipment is increasingly widely used in the machining field. As a crucial connecting component of shaft parts, the forging accuracy and efficiency of flanges directly affect equipment performance. However, existing flange forging tables still face significant technical bottlenecks in terms of clamping stability, repositioning flexibility, and adaptability to multiple sizes, specifically manifested in the following problems:

[0003] Traditional forging tables often employ fixed clamping slots or unidirectional clamping structures. During forging, workpieces are prone to shaking or shifting due to impact forces, leading to a decrease in forging accuracy. For example, some existing forging equipment uses a turntable to switch the feed chute, but lacks a dynamic locking mechanism. Under hydraulic impact, the workpiece is easily deviated from the machining center, causing a "deviation" phenomenon. Furthermore, existing equipment often relies on manual operation or a single rotating mechanism to adjust the workpiece position, making it difficult to achieve multi-face synchronous processing of complex forgings. For instance, although the multi-angle clamping device for forging stainless steel flanges for nuclear power plants proposed in patent CN218362267U can adjust the flange position by rotating the table column, it relies on manual operation, resulting in low efficiency and inability to be linked with the forging action in real time. At the same time, the clamping structure of most existing forging tables is designed for a single size, making it difficult to adapt to flanges of different diameters. For example, the feed chute of the forging table in the flange forging equipment proposed in patent CN202322185903 is of a uniform size, which cannot accommodate workpieces of multiple specifications, requiring frequent changes of clamps and significantly affecting production efficiency.

[0004] To address these issues, we provide a self-clamping and transpositioning machine tool spindle flange forging table and its transposition method. Summary of the Invention

[0005] The purpose of this invention is to provide a self-clamping and repositioning machine tool spindle flange forging table and its repositioning method, which integrates self-clamping, automatic repositioning, and multi-size adaptation to improve machining accuracy and efficiency, reduce labor costs, and solve the problems mentioned in the background art.

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

[0007] A self-clamping and repositioning machine tool spindle flange forging table includes a machine table mounted on a machine frame, a support frame mounted above the machine table, a forging hammer mounted on the support frame for forging the spindle flange, a first spindle rotatably mounted on the machine frame, and the first spindle and the support frame cooperating through a first linkage mechanism. When the first spindle rotates, it drives the support frame to move vertically up and down, thereby driving the forging hammer to move vertically up and down reciprocally.

[0008] The machine base is rotatably provided with a trough, and the trough is provided with multiple arc-shaped clamps distributed circumferentially at equal angles. The multiple arc-shaped clamps can expand outward or converge synchronously to clamp and fix the main shaft flange placed on the trough.

[0009] The first spindle and the tank are connected by a second linkage mechanism. When the first spindle rotates, it will drive the tank to rotate intermittently, thereby driving the spindle flange placed on the tank to automatically and intermittently change position.

[0010] As described above, a self-clamping and repositioning machine tool spindle flange forging table is provided with a first motor on the frame. The output end of the first motor is connected to the first spindle through a coupling to drive the first spindle to rotate.

[0011] As described above, a self-clamping and repositioning machine tool spindle flange forging table includes the following: the first linkage structure includes a first secondary shaft rotatably mounted on the machine frame. The first secondary shaft is driven to rotate synchronously with the first main shaft via a first gear mechanism. The first main shaft rotates simultaneously with the first secondary shaft. Connecting rods are respectively provided at both ends of the first secondary shaft. A connecting rod is provided on the support frame. A first swing arm is provided between the connecting rod and the first secondary shaft. The two ends of the first swing arm are respectively hinged to the connecting rod and the connecting rod. A limiting component is provided on the machine frame when the connecting rod moves vertically up and down.

[0012] As described above, a self-clamping and repositioning machine tool spindle flange forging table includes a first bevel gear ring disposed on a first secondary shaft and a first bevel gear disposed on a first main shaft, wherein the first bevel gear ring meshes with the first bevel gear.

[0013] The limiting component includes two fixing plates mounted on the frame and located at both ends of the connecting rod. Limiting grooves are formed on the fixing plates, and the ends of the connecting rod are movably engaged inside the limiting grooves.

[0014] As described above, a self-clamping and repositioning machine tool spindle flange forging table has the following features: a second spindle is rotatably mounted on the groove, and a first turntable is movably engaged inside the groove on the second spindle. An arc-shaped groove is formed on the first turntable, and a locking pin is movably engaged inside the arc-shaped groove. A movable rod is mounted on the locking pin. A forging table for placing the spindle flange is provided on the groove, and the movable rod passes through the forging table. One end of the movable rod is fixed to an arc-shaped clamping plate.

[0015] As described above, a self-clamping and repositioning machine tool spindle flange forging table has a second motor installed at the bottom of the groove. The output end of the second motor is connected to the second spindle via a coupling to drive the second spindle to rotate.

[0016] As described above, a self-clamping and repositioning machine tool spindle flange forging table includes a second linkage mechanism comprising a second auxiliary shaft rotatably mounted on the machine frame. The second auxiliary shaft is driven to rotate with the first main shaft via a second gear mechanism. The rotation of the first main shaft drives the second auxiliary shaft to rotate. A third turntable is rotatably mounted on the machine table. The second auxiliary shaft and the third turntable are connected via a first transmission mechanism. The rotation of the second auxiliary shaft drives the third turntable to rotate clockwise and counterclockwise. The third turntable is connected to the groove via an intermittent mechanism. The clockwise and counterclockwise rotation of the third turntable drives the groove to rotate intermittently.

[0017] As described above, a self-clamping and repositioning machine tool spindle flange forging table: the second gear mechanism includes a second bevel gear ring disposed on the first spindle and a second bevel gear disposed on the second counterspindle, wherein the second bevel gear ring meshes with the second bevel gear;

[0018] The first transmission mechanism includes a second turntable disposed on a second secondary shaft, a protruding rod disposed on the second turntable, and a second swing arm disposed at the axis of the third turntable. A rectangular groove is provided on the second swing arm, and the protruding rod is movably engaged inside the rectangular groove.

[0019] As described above, a self-clamping and repositioning machine tool spindle flange forging table includes an intermittent mechanism comprising a first external gear ring rotatably mounted on the machine base and located on the outer periphery of a third turntable. The inner wall of the first external gear ring has a slot. An elastic lever is provided on the third turntable, and a clamping plate is hinged to the third turntable. The end of the clamping plate is movably embedded and clamped inside the slot. One end of the elastic lever abuts against one side of the clamping plate. A fixed groove is provided on the machine base, and a wedge plate is movably clamped inside the fixed groove. A spring connects the wedge plate to the inner wall of the fixed groove. One end of the wedge plate meshes with the teeth of the first external gear ring. A second external gear ring is provided on the groove, and the first external gear ring meshes with the second external gear ring.

[0020] A method for transpositioning a self-clamping transpositioning machine tool spindle flange forging table includes the following steps:

[0021] S1. First, place the main spindle flange on the forging table at the top of the tank. Start the second motor to drive the second main spindle to rotate, which in turn drives the first turntable to rotate. The rotation of the first turntable causes multiple arc-shaped clamping plates to converge synchronously to clamp and fix the tank.

[0022] S2, start the first motor to drive the first main shaft to rotate. When the first main shaft rotates, it will drive the connecting rod on the first secondary shaft to rotate. The rotation of the connecting rod will drive the first swing arm to swing and drive the support frame at the bottom of the connecting rod to move vertically up and down. In turn, it will drive the forging hammer at the bottom of the support frame to move vertically up and down. When the forging hammer moves downward, it will repeatedly forge the clamped main shaft flange.

[0023] S3, when the first main shaft rotates, the second auxiliary shaft rotates synchronously. The rotation of the second auxiliary shaft drives the third turntable to rotate clockwise and counterclockwise. When the third turntable rotates counterclockwise, the clamping plate is embedded in the groove, thus overcoming the elastic compression of the wedge plate on the first outer gear ring and driving the first outer gear ring to rotate counterclockwise. When the third turntable rotates clockwise, the first outer gear ring is subjected to the elastic compression of the wedge plate, and the clamping plate will squeeze the elastic lever to deflect it. The first outer gear ring remains stationary, thereby causing the first outer gear ring to rotate intermittently, driving the groove to rotate intermittently, and thus causing the main shaft flange clamped on the groove to automatically change position during forging.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] A trough is rotatably mounted on the machine base, and multiple arc-shaped clamping plates are arranged circumferentially at equal angles on the trough. The multiple arc-shaped clamping plates can expand outward or converge synchronously. In use, the main shaft flange is placed on the trough, and the second motor is started to drive the second main shaft to rotate, which in turn drives the first turntable to rotate. The rotation of the first turntable causes the multiple arc-shaped clamping plates to converge synchronously to clamp and fix the trough. Thus, this invention adopts a circumferential clamping method to fix the workpiece in all directions, solving the problem that workpieces clamped in one direction are prone to shaking or displacement due to impact force during forging. In addition, by controlling the convergence degree of the multiple arc-shaped clamping plates, it can adapt to flanges of different diameters, eliminating the need for frequent clamping changes, and has strong adaptability, thereby improving production efficiency.

[0026] In addition, while the first spindle rotates, it drives the support frame to move vertically up and down, thereby driving the forging hammer to move vertically up and down reciprocally to forge the workpiece. At the same time, while the first spindle rotates, it drives the tank to rotate intermittently, thereby driving the spindle flange placed on the tank to automatically and intermittently change position during forging. By intermittently rotating the workpiece, it ensures that the surface of the spindle flange workpiece is uniformly stressed during forging, optimizes the flow direction of metal fibers, and ensures forging quality. At the same time, it no longer relies on manual operation and can be linked with the forging action in real time, resulting in high efficiency. Attached Figure Description

[0045] As a further embodiment of the present invention, the first linkage structure includes a first secondary shaft 6 rotatably mounted on the frame 1. The first secondary shaft 6 is driven to the first main shaft 5 by a first gear mechanism. When the first main shaft 5 rotates, it will drive the first secondary shaft 6 to rotate synchronously. Connecting rods 7 are respectively provided at both ends of the first secondary shaft 6. A connecting rod 9 is provided on the support frame 3. A first swing arm 8 is provided between the connecting rod 9 and the first secondary shaft 6. The two ends of the first swing arm 8 are respectively hinged to the connecting rod 7 and the connecting rod 9. A limiting component is provided on the frame 1 when the connecting rod 9 moves vertically up and down.

[0046] In this embodiment, the first motor 14 is started to drive the first main shaft 5 to rotate. When the first main shaft 5 rotates, it will drive the connecting rod 7 on the first secondary shaft 6 to rotate. The rotation of the connecting rod 7 will drive the first swing arm 8 to swing and drive the connecting rod 9 to move vertically up and down. This will drive the support frame 3 at the bottom of the connecting rod 9 to move vertically up and down, and then drive the forging hammer 4 at the bottom of the support frame 3 to move vertically up and down. When the forging hammer 4 moves downward, it will repeatedly forge the clamped main shaft flange.

[0047] As a further embodiment of the present invention, the first gear mechanism includes a first bevel gear ring 12 disposed on the first secondary shaft 6 and a first bevel gear 13 disposed on the first main shaft 5, wherein the first bevel gear ring 12 meshes with the first bevel gear 13.

[0049] In this embodiment, when the first main shaft 5 rotates, it will drive the first bevel gear 13 to rotate. The first bevel gear ring 12 meshes with the first bevel gear 13 to drive the first bevel gear ring 12 to rotate. When the first bevel gear ring 12 rotates, it will drive the first secondary shaft 6 to rotate synchronously.

[0050] When the connecting rod 9 moves vertically up and down, the end of the connecting rod 9 is movably engaged in the limiting groove 11 to limit the vertical movement of the connecting rod 9 and prevent it from shifting position during vertical movement.

[0051] As a further embodiment of the present invention, a second main shaft 18 is rotatably mounted on the groove 15, and a first turntable 17 is movably engaged inside the groove 15 on the second main shaft 18. An arc-shaped groove 20 is opened on the first turntable 17, and a locking post 21 is movably engaged inside the arc-shaped groove 20. A movable rod 22 is mounted on the locking post 21. A forging table 39 for placing the main shaft flange is provided on the groove 15. The movable rod 22 is disposed through the forging table 39, and one end of the movable rod 22 is fixed to the arc-shaped clamping plate 16.

[0052] In this embodiment, the second spindle 18 is driven to rotate, which in turn drives the first turntable 17 to rotate. The rotation of the first turntable 17 causes the locking pin 21 to slide in the arc groove 20, thereby driving the movable rod 22 to move within the forging table 39. This, in turn, drives the arc-shaped clamping plates 16 at the ends of the multiple movable rods 22 to expand outward or converge synchronously to clamp and fix the spindle flange workpiece placed on the forging table 39.

[0053] As a further embodiment of the present invention, a second motor 19 is provided at the bottom of the tank 15, and the output end of the second motor 19 is connected to the second main shaft 18 through a coupling to drive the second main shaft 18 to rotate.

[0054] In this embodiment, the second motor 19 is electrically connected to an external power source via a wire, and starting the second motor 19 can drive the second spindle 18 to rotate.

[0055] As a further embodiment of the present invention, the second linkage mechanism includes a second auxiliary shaft 23 rotatably mounted on the frame 1. The second auxiliary shaft 23 is driven to the first main shaft 5 by a second gear mechanism. When the first main shaft 5 rotates, it drives the second auxiliary shaft 23 to rotate. A third turntable 30 is rotatably mounted on the machine base 2. The second auxiliary shaft 23 and the third turntable 30 are connected by a first transmission mechanism. When the second auxiliary shaft 23 rotates, it drives the third turntable 30 to rotate clockwise and counterclockwise. The third turntable 30 is connected to the tank 15 by an intermittent mechanism. When the third turntable 30 rotates clockwise and counterclockwise, it drives the tank 15 to rotate intermittently.

[0056] In this embodiment, the rotation of the first main shaft 5 drives the rotation of the second auxiliary shaft 23. The second auxiliary shaft 23 and the third turntable 30 are connected by a first transmission mechanism. The rotation of the second auxiliary shaft 23 drives the third turntable 30 to rotate clockwise and counterclockwise. The third turntable 30 and the tank 15 are connected by an intermittent transmission mechanism. When the third turntable 30 rotates clockwise and counterclockwise, it drives the tank 15 to rotate intermittently.

[0057] As a further embodiment of the present invention, the second gear mechanism includes a second bevel gear ring 24 disposed on the first main shaft 5 and a second bevel gear 25 disposed on the second secondary shaft 23, wherein the second bevel gear ring 24 meshes with the second bevel gear 25;

[0058] The first transmission mechanism includes a second turntable 26 mounted on a second secondary shaft 23, a protruding rod 27 mounted on the second turntable 26, and a second swing arm 28 mounted at the axis of the third turntable 30. A rectangular groove 29 is provided on the second swing arm 28, and the protruding rod 27 is movably engaged inside the rectangular groove 29.

[0059] In this embodiment, when the first main shaft 5 rotates, it will drive the second bevel gear ring 24 to rotate. The second bevel gear ring 24 meshes with the second bevel gear 25 to drive the second bevel gear 25 to rotate, thereby driving the second auxiliary shaft 23 to rotate synchronously.

[0060] When the second secondary shaft 23 rotates, it will cause the protruding rod 27 at the bottom of the second turntable 26 to slide in the rectangular groove 29 opened on the second swing arm 28, thereby causing the second swing arm 28 to swing back and forth, so as to drive the third turntable 30 at the end of the second swing arm 28 to rotate clockwise and counterclockwise.

[0061] As a further embodiment of the present invention, the intermittent mechanism includes a first external gear ring 31 rotatably mounted on the machine base 2 and located on the outer periphery of the third turntable 30. The inner sidewall of the first external gear ring 31 is provided with a slot 33. An elastic lever 35 is provided on the third turntable 30. A locking plate 34 is hinged on the third turntable 30. The end of the locking plate 34 is movably embedded and locked inside the slot 33. One end of the elastic lever 35 abuts against one side of the locking plate 34. A fixed groove 36 is provided on the machine base 2. A wedge plate 38 is movably locked inside the fixed groove 36. A spring 37 is connected between the wedge plate 38 and the inner wall of the fixed groove 36. One end of the wedge plate 38 meshes with the teeth of the first external gear ring 31. A second external gear ring 32 is provided on the groove 15. The first external gear ring 31 meshes with the second external gear ring 32.

[0062] In this embodiment, when the first main shaft 5 rotates, the second auxiliary shaft 23 rotates synchronously. The rotation of the second auxiliary shaft 23 drives the third turntable 30 to rotate clockwise and counterclockwise. When the third turntable 30 rotates counterclockwise, the clamping plate 34 is embedded in the clamping groove 33, thus overcoming the elastic compression of the wedge plate 38 on the first external gear ring 31 and driving the first external gear ring 31 to rotate counterclockwise. When the third turntable 30 rotates clockwise, the first external gear ring 31 is subjected to the elastic compression of the wedge plate 38, and the clamping plate 34 will squeeze the elastic lever 35 to cause deflection. The first external gear ring 31 is insufficient to overcome the elastic compression of the wedge plate 38 and drive it to rotate, that is, the first external gear ring 31 remains stationary, thereby causing the first external gear ring 31 to rotate intermittently and drive the groove 15 to rotate intermittently, thereby causing the main shaft flange clamped on the groove 15 to perform intermittent automatic rotation and repositioning during forging.

[0063] In use, firstly, the main spindle flange is placed on the forging table 39 at the top of the groove 15. Then, the second motor 19 is started to drive the second main spindle 18 to rotate, which in turn drives the first turntable 17 to rotate. The rotation of the first turntable 17 causes multiple arc-shaped clamping plates 16 to converge synchronously and clamp the groove 15. Next, the first motor 14 is started to drive the first main spindle 5 to rotate. When the first main spindle 5 rotates, it drives the connecting rod 7 on the first auxiliary spindle 6 to rotate. The rotation of the connecting rod 7 causes the first swing arm 8 to swing and causes the support frame 3 at the bottom of the connecting rod 9 to move vertically up and down. This, in turn, causes the forging hammer 4 at the bottom of the support frame 3 to move vertically up and down. When the forging hammer 4 moves downwards, it repeatedly forges the clamped main spindle flange. When the first main spindle 5 rotates, the second auxiliary spindle 23 rotates synchronously, and the rotation of the second auxiliary spindle 23 drives the third... The turntable 30 rotates clockwise and counterclockwise. When the third turntable 30 rotates counterclockwise, the clamping plate 34 is embedded in the clamping groove 33, thus overcoming the elastic compression of the first outer gear ring 31 by the wedge plate 38, causing the first outer gear ring 31 to rotate counterclockwise. When the third turntable 30 rotates clockwise, the first outer gear ring 31 is subjected to the elastic compression of the wedge plate 38, and the clamping plate 34 will squeeze the elastic lever 35 to cause deflection. The first outer gear ring 31 remains stationary, thereby causing the first outer gear ring 31 to rotate intermittently, driving the groove 15 to rotate intermittently. This causes the main spindle flange clamped on the groove 15 to automatically rotate and change position during forging. By intermittently rotating the main spindle flange workpiece, in conjunction with the forging hammer 4 forging, the surface of the main spindle flange workpiece is subjected to uniform force during forging, optimizing the flow direction of metal fibers.

[0064] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.

A locking plate (34) is hinged to the third turntable (30). The end of the locking plate (34) is movably embedded and locked inside the slot (33). One end of the elastic lever (35) abuts against the locking plate. (34) On one side, a fixed groove (36) is provided on the machine base (2). A wedge plate (38) is movably engaged inside the fixed groove (36). A spring (37) is connected between the wedge plate (38) and the inner wall of the fixed groove (36). One end of the wedge plate (38) meshes with the teeth of the first external gear ring (31). A second external gear ring (32) is provided on the groove (15). The first external gear ring (31) meshes with the second external gear ring (32).

10. A transposition method for a self-clamping transposition machine tool spindle flange forging table as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. First, place the main spindle flange on the forging table (39) at the top of the tank (15), start the second motor (19) to drive the second main spindle (18) to rotate and drive the first turntable (17) to rotate. The rotation of the first turntable (17) drives multiple arc-shaped clamps (16) to converge synchronously to clamp and fix the tank (15). S2, start the first motor (14) to drive the first main shaft (5) to rotate. When the first main shaft (5) rotates, it will drive the connecting rod (7) on the first secondary shaft (6) to rotate. The rotation of the connecting rod (7) will drive the first swing arm (8) to swing and drive the support frame (3) at the bottom of the connecting rod (9) to move vertically up and down, thereby driving the forging hammer (4) at the bottom of the support frame (3) to move vertically up and down. When the forging hammer (4) moves downward, it will repeatedly forge the clamped main shaft flange. S3, when the first main shaft (5) rotates, the second auxiliary shaft (23) rotates synchronously. The rotation of the second auxiliary shaft (23) drives the third turntable (30) to rotate clockwise and counterclockwise. When the third turntable (30) rotates counterclockwise, since the clamping plate (34) is embedded in the clamping groove (33), it can overcome the elastic compression of the wedge plate (38) on the first external gear ring (31) and drive the first external gear ring (31) to rotate counterclockwise. When the third turntable (30) rotates clockwise, the first external gear ring (31) is subjected to the elastic compression of the wedge plate (38). The clamping plate (34) will squeeze the elastic lever (35) and deflect it. The first external gear ring (31) remains stationary, so that the first external gear ring (31) rotates intermittently and drives the groove (15) to rotate intermittently, thereby causing the main shaft flange clamped on the groove (15) to automatically change position during forging.
