Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting processing technology, and more specifically to a multi-degree-of-freedom flipping fixture for mineral casting processing. Background Technology
[0002] With the rapid growth in demand from modern industry for high-precision, complex-structured mineral castings (such as machine tool beds, hydraulic supports, and mining machinery parts), the processing technology places higher demands on the adaptability of tooling and equipment. In the processing of mineral castings, the workpieces are large, heavy, and have complex geometries, requiring multi-faceted precision machining.
[0003] As shown in the prior art published in CN222345344U, although this prior art uses a combination of a two-way lead screw, rectangular block, guide rod, sliding block, support block, moving block, rotating shaft, rotating seat, fixed block, and clamping block to centrally clamp casting fixtures of different sizes, and uses a combination of a connecting block, positioning rod, positioning hole, rotating rod, driving gear, driven gear, rotating shaft, spring, limit ring, rotating seat, and U-shaped frame to angularly rotate the fixed casting fixture, thus completing the machining of multiple surfaces of the casting fixture in one clamping operation, reducing the time for switching and re-clamping, and improving machining efficiency, the clamping components in this prior art are only driven at one end, while the other end moves through friction. This affects the stability of the casting during machining. If the friction at one end of the casting decreases, the clamping stability will be affected, and the casting may fall and be damaged. Utility Model Content
[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a multi-degree-of-freedom flipping fixture for processing mineral castings. By engaging the linkage plate with the linkage hole, the linkage plate can drive two first pulleys to rotate synchronously. The first pulleys drive the second pulley via a belt, and the second pulley drives the clamping plate to rotate via the linkage shaft. The two clamping plates then synchronously adjust the angle of the mineral casting, ensuring that the forces on both ends of the mineral casting are balanced, preventing pressure imbalance that could lead to loosening of the mineral casting, and ensuring the stability of the mineral casting during processing, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-degree-of-freedom flipping fixture for processing mineral castings, including a processing table, a linkage plate at the bottom of the processing table, first pulleys on the outside of both ends of the linkage plate, a linkage shaft on the top of each of the two first pulleys, and a clamping plate for fixing the castings installed on the side of the two linkage shafts that are close to each other. Each linkage shaft is fitted with a second pulley, and the second pulley and the first pulley are driven by a belt. The first pulley has a linkage hole on one side corresponding to the linkage plate, and the linkage plate is located inside the linkage hole.
[0006] In a preferred embodiment, the cross-section of the linkage plate and the cross-section of the linkage hole are both rectangular, and the outer side of the linkage plate is in contact with the inner wall of the linkage hole.
[0007] In a preferred embodiment, both sides of the linkage plate are provided with fixing plates, the top of the fixing plates is fixed to the bottom of the processing table, and both ends of the linkage plate are movably connected to the two fixing plates respectively through rotating shafts; A drive motor is mounted on one of the fixed plates on the side away from the linkage plate. The output shaft of the drive motor passes through the fixed plate and is fixed together with the rotating shaft on the linkage plate.
[0008] In a preferred embodiment, the top of the processing table is provided with a groove, and an adjusting rod is installed inside the groove via a bearing. Adjusting seats are fitted on both ends of the adjusting rod. The top of the adjusting seat passes through the groove and extends to the top of the processing table. The end of the linkage shaft away from the clamping plate is movably connected to the adjusting seat via a bearing. The bottom end of the adjusting seat passes through the groove and extends to the bottom of the processing table. The bottom end of the adjusting seat is sleeved on the outside of the linkage plate. The adjusting seat has a through hole on one side corresponding to the linkage plate. The linkage plate is located inside the through hole. A support ring is installed on the side of the first pulley near the adjusting seat. The support ring is movably connected to the adjusting seat through a bearing.
[0009] In a preferred embodiment, a servo motor is mounted on one side of the processing table, and the output shaft of the servo motor passes through the processing table and is fixed together with the adjusting rod.
[0010] In a preferred embodiment, the threads at both ends of the adjusting rod are in opposite directions, and the threads at both ends of the adjusting rod are symmetrically distributed about the central axis of the adjusting rod.
[0011] In a preferred embodiment, both the cross-section of the adjusting seat and the cross-section of the groove are rectangular, and the outside of the adjusting seat is in contact with the inner wall of the groove.
[0012] The technical effects and advantages of this utility model are as follows: By engaging the linkage plate with the linkage hole, the linkage plate can drive the two first pulleys to rotate synchronously. The first pulley drives the second pulley through the belt, and the second pulley drives the clamping plate to rotate through the linkage shaft. The two clamping plates then synchronously adjust the angle of the mineral casting and make the force on both ends of the mineral casting even, so as to avoid the mineral casting from loosening due to pressure imbalance and ensure the stability of the mineral casting during processing.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Refer to the instruction manual appendix Figure 1-5 This utility model provides a multi-degree-of-freedom flipping fixture for processing mineral castings, including a processing table 1. The bottom of the processing table 1 is provided with a linkage plate 2. Both ends of the linkage plate 2 are fitted with first pulleys 3. The top of the two first pulleys 3 is provided with a linkage shaft 4. The side of the two linkage shafts 4 that are close to each other is equipped with a clamping plate 5 for fixing the casting. Each linkage shaft 4 is fitted with a second pulley 6. The second pulley 6 and the first pulley 3 are driven by a belt 7. The first pulley 3 is provided with a linkage hole 8 on the side corresponding to the linkage plate 2. The linkage plate 2 is located inside the linkage hole 8.
[0017] When the operator uses the aforementioned processing table 1 to process the mineral casting, it is necessary to clamp and fix the mineral casting. Therefore, a groove 11 is provided on the top of the processing table 1. An adjusting rod 12 is installed inside the groove 11 and is movably connected by a bearing. Adjusting seats 13 are fitted on both ends of the adjusting rod 12. The top end of the adjusting seat 13 passes through the groove 11 and extends to the top of the processing table 1. The end of the linkage shaft 4 away from the clamping plate 5 is movably connected to the adjusting seat 13 through a bearing. The bottom end of the adjusting seat 13 passes through the groove 11 and extends to the bottom of the processing table 1. The bottom end of the adjusting seat 13 is fitted on the outside of the linkage plate 2. A through hole 14 is provided on one side of the adjusting seat 13 corresponding to the linkage plate 2. The linkage plate 2 is located inside the through hole 14. A support ring 15 is installed on the side of the first pulley 3 near the adjusting seat 13. The support ring 15 is movably connected to the adjusting seat 13 through a bearing.
[0018] In this way, the adjusting rod 12 can be used to move the two adjusting seats 13. Because the threads at both ends of the adjusting rod 12 are opposite in direction and symmetrically distributed about its central axis, the adjusting seats 13 can move synchronously inward or outward, facilitating the clamping of different sizes of mineral castings by the two clamping plates 5. Furthermore, since both the cross-section of the adjusting seat 13 and the cross-section of the groove 11 are rectangular, and the outer surface of the adjusting seat 13 contacts the inner wall of the groove 11, the groove 11 can limit and guide the movement of the adjusting seat 13, ensuring stability when the adjusting seat 13 moves the clamping plate 5 and preventing skewing of the adjusting seat 13 and clamping plate 5 during the movement process.
[0019] To improve the ease of maneuvering the adjusting seats 13, a servo motor 16 is installed on one side of the processing table 1. The output shaft of the servo motor 16 passes through the processing table 1 and is fixed together with the adjusting rod 12. In this way, the servo motor 16 can drive the adjusting rod 12 to rotate, and the adjusting rod 12 can then drive the two adjusting seats 13 to move inward or outward synchronously, thereby improving the ease of fixing the mineral casting.
[0020] To facilitate multi-faceted processing of mineral castings, multi-angle adjustment of the mineral castings is required. To improve the convenience of adjusting the mineral castings, fixed plates 9 are provided on both sides of the linkage plate 2. The top of the fixed plate 9 is fixed to the bottom of the processing table 1. Both ends of the linkage plate 2 are movably connected to the two fixed plates 9 through rotating shafts. A drive motor 10 is installed on the side of one of the fixed plates 9 away from the linkage plate 2. The output shaft of the drive motor 10 passes through the fixed plate 9 and is fixed to the rotating shaft on the linkage plate 2.
[0021] In this way, the drive motor 10 can drive the linkage plate 2 to rotate. Since the cross-section of the linkage plate 2 and the cross-section of the linkage hole 8 are both rectangular, and the outside of the linkage plate 2 is in contact with the inner wall of the linkage hole 8, the linkage plate 2 can drive the two first pulleys 3 to rotate by engaging with the linkage hole 8. The two first pulleys 3 drive the second pulley 6 to rotate by the corresponding belt 7. The second pulley 6 then drives the linkage shaft 4 to drive the clamping plate 5 to rotate. The clamping plate 5, together with the mineral casting, can adjust the angle. This can make the force on both ends of the mineral casting even, avoid the mineral casting from loosening due to pressure imbalance, and ensure the stability of the mineral casting during processing.
[0022] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
