Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for spinning machines, and in particular to a workpiece anti-deformation fixture for spinning machine processing. Background Technology

[0002] As is well known, a spinning machine is a high-efficiency processing equipment that uses rotational motion and feed pressure to plastically deform metal sheets or pipes under the action of a mold, thereby forming parts of a specific shape. Its working principle is to fix the workpiece on a rotating spindle, and apply pressure to the workpiece along a preset trajectory through a spinning wheel, so that the material gradually conforms to the mold contour during the rotation process, and finally completes the forming process of the part. Spinning machines are widely used in aerospace, automobile manufacturing, kitchenware production and other fields, and can process high-precision parts such as thin-walled cylindrical parts, disc-shaped parts, and irregular-shaped pipes.

[0003] When using an existing spinning machine, it has been found that the workpiece is usually placed on a placement plate and fixed by mechanical clamping devices (such as bolt clamps, pneumatic grippers, etc.). Due to the uneven distribution of clamping force, the workpiece is prone to local excessive or insufficient force during rotation processing, which may lead to a decrease in processing accuracy, thereby reducing the efficiency and effect of processing and resulting in poor practicality. Utility Model Content

[0021] like Figures 1 to 4As shown, this utility model discloses a workpiece anti-deformation fixture for spinning, comprising an operating table 1, a rotating spindle 2, and a placement plate 3. The rotating spindle 2 is mounted on the top of the operating table 1, and the placement plate 3 is mounted on the top of the rotating spindle 2. The fixture also includes four sets of connecting blocks 4, four sets of fixed seats 5, connecting components, and an adjustment mechanism. The placement plate 3 has a working cavity with evenly distributed sliding holes on its top. The four sets of connecting blocks 4 are slidably connected to the outer sides of one set of sliding holes in the working cavity of the placement plate 3. The tops of the four sets of connecting blocks 4 are connected to the bottoms of one set of fixed seats 5 via connecting components, and the bottoms of the four sets of connecting blocks 4 are equipped with adjustment mechanisms. The operating table serves as a basic support component, supporting the rotating spindle and the placement plate. After the workpiece is placed on the placement plate, the adjustment mechanism is activated, causing the connecting blocks to slide within the sliding holes in the working cavity of the placement plate. The connecting blocks drive the fixed seats to move via the connecting components, clamping the workpiece from four directions. The anti-slip pads on the fixed base contact the workpiece surface, enhancing clamping stability. Through the coordinated work of multiple components, the workpiece can be clamped in all directions, effectively avoiding the problem of excessive or insufficient local force, thereby improving the efficiency and effect of processing and thus enhancing its practicality.

[0022] As a preferred embodiment of the above, the connecting assembly includes four sets of connecting screws 6, each of the four sets of connecting blocks 4 having a set of threaded holes at its top, the bottom of each of the four sets of connecting screws 6 being threadedly connected to a set of threaded holes in the connecting blocks 4, and four sets of fixing seats 5 having a set of reserved holes. The outer top of each of the four sets of connecting screws 6 is rotatably connected to the inner side of a reserved hole in a fixing seat 5. By manually rotating the connecting screws, the position of the fixing seats can be adjusted in a personalized manner for workpieces of different shapes and sizes, thus enhancing practicality.

[0023] As a preferred embodiment of the above, the adjustment mechanism includes a ring gear 7, a drive bevel gear 8, a rotary motor 9, and a sliding assembly. The bottom of the working cavity of the placement plate 3 is rotatably connected to the bottom of the ring gear 7. A reserved hole is provided on the left front side of the working cavity of the placement plate 3. The rotary motor 9 is provided on the left front side of the placement plate 3. The output end of the rotary motor 9 passes through the reserved hole and connects to the inner side of the drive bevel gear 8. The bottom of the drive bevel gear 8 and the top side of the ring gear 7 are engaged and locked. The bottom of the four sets of connecting blocks 4 are engaged with the top of the ring gear 7 through the sliding assembly. When the rotary motor is started, its output end drives the drive bevel gear to rotate. The drive bevel gear engages with the ring gear, driving the ring gear to rotate at the bottom of the working cavity of the placement plate. When the ring gear rotates, it drives the four sets of connecting blocks to slide through the sliding assembly, synchronously driving the fixed seat to move towards the workpiece, realizing the clamping action of the workpiece. When the rotary motor is started in the opposite direction, the clamping can be released. This realizes the automated control of the clamping action, which greatly improves the work efficiency compared with the traditional manual adjustment method, thus enhancing its practicality.

[0024] In a preferred embodiment, the sliding assembly includes four sets of connecting plates 10, four sets of mounting rings 11, four sets of fixing blocks 12, four sets of first screws 13, and four sets of driven bevel gears 14. The bottoms of the four sets of connecting blocks 10 are respectively connected to the tops of one set of connecting plates 10, and the bottoms of the four sets of connecting plates 10 slide in close contact with the bottom of the working cavity of the placement plate 3. Each of the four sets of connecting plates 10 is provided with a set of reserved holes, and a set of mounting rings 11 is provided inside each of the reserved holes. The inner sides of the four sets of mounting rings 11 are provided with threads. The outer sides of the four sets of first screws 13 are respectively threaded to the inner sides of the set of mounting rings 11. The two ends of the fixing blocks 12 are respectively connected to the top and bottom center areas of the working cavity of the placement plate 3. One end of each of the four sets of first screws 13 is rotatably connected to one end of each set of fixing blocks 12, and the other end of each of the four sets of first screws 13 is rotatably connected to one end of the working cavity of the placement plate 3. The four sets of first screws 13 are connected, with a set of driven bevel gears 14 respectively installed at one end of their outer sides. The bottoms of the four sets of driven bevel gears 14 are respectively engaged with the top of the ring gear 7. When the ring gear rotates, it drives the driven bevel gears that mesh with it to rotate. The driven bevel gears are fixed on the first screws, which in turn causes the first screws to rotate within the mounting ring. Since the mounting ring is fixed to the connecting plate and one end of the first screw is rotatably connected to the fixing block, the rotation of the first screw is converted into the connecting plate sliding linearly along the bottom of the working cavity of the placement plate. The connecting plate drives the connecting block and the fixing seat to move, thereby clamping or releasing the workpiece. The dual protection of threaded transmission and gear meshing ensures the accuracy and synchronization of the movement of the fixing seat. At the same time, the setting of this component makes the movement trajectory of the fixing seat controllable, which can adapt to the clamping requirements of workpieces of different sizes, improve the versatility of the fixture, and thus enhance its practicality.

[0025] As a preferred embodiment of the above, it also includes four sets of anti-slip pads 15, with one set of anti-slip pads 15 respectively provided on the outer side of the four sets of fixing seats 5; this enhances the clamping stability of the fixture on the workpiece, thus enhancing its practicality.

[0026] As a preferred embodiment of the above, it also includes four sets of rotating handles 16, with a set of rotating handles 16 respectively provided on the top of the four sets of connecting screws 6; this allows the operator to quickly rotate the connecting screws, thus enhancing practicality.

[0027] As a preferred embodiment of the above, the four outer sides of the four sets of fixing seats 5 are respectively provided with arc surfaces of different curvatures; according to the outer contour of the workpiece, the arc surface of the outer side of the fixing seat corresponding to the curvature is selected to contact the workpiece, which significantly improves the adaptability of the fixture to workpieces of different shapes, thus enhancing its practicality.

[0028] This utility model discloses a workpiece anti-deformation fixture for spinning machine processing. During operation, the workpiece to be processed is placed on the placement plate. Based on the workpiece shape, the outer arc surface of the fixing seat with a suitable curvature is selected to face the workpiece. Then, the rotary motor is started, driving the driving bevel gear to rotate. Through meshing with the ring gear, the ring gear is driven to rotate. When the ring gear rotates, it drives the driven bevel gear and the first screw to rotate, causing the connecting plate to slide at the bottom of the working cavity of the placement plate. The connecting block moves accordingly in the sliding hole. The fixing seat moves towards the workpiece and gradually applies clamping force until the anti-slip pad is tightly attached to the workpiece surface, completing the clamping. After confirming that the workpiece is firmly clamped, the spinning machine is started, and the rotating spindle drives the placement plate and workpiece to rotate at high speed for spinning processing. Before completing the above actions, the workpiece is first moved to the position required by the user.

[0030] In this utility model, the terms "first," "second," and "third" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
