TECHNICAL FIELD

[0001] The application belongs to the technical field of machine tool swing shaft head, and particularly relates to a balancing device for a swing shaft head of a vertical five-axis linkage machine tool. BACKGROUND

[0002] In the field of modern mechanical processing, vertical five-axis linkage machine tools are widely used in many high-end manufacturing industries such as aerospace, automobile manufacturing and mold processing due to their high precision, high efficiency and the ability to complete complex curved surface processing. The stability and precision of the swing shaft head, as one of the key components of the vertical five-axis linkage machine tool, directly affect the machining quality of the entire machine tool. The swing shaft head balancing device is a core component that ensures the stable operation of the swing shaft head, reduces vibration and improves machining precision.

During subsequent swing of the swing shaft head 6, the shaft rod 61 rotates and drives the gear 5 to rotate, and the rotation of the gear 5 drives the rack 41 and the balance sliding seat 4 to move transversely, so that the balance sliding seat 4 is well supported by the plurality of balls 32 on the inner side of the rectangular sliding groove 31, thereby achieving the balancing support effect and preventing the shaft rod 61 from sinking. For specific working principles, reference can be made to the contents recorded in the existing patent with the publication number CN216681358U; Two support rods 2 are installed on the bottom surface of the balance support plate 3, and the bottom ends of the support rods 2 penetrate to the bottom of the support plate 1, so that the balance support plate 3 can move up and down on the top of the support plate 1, facilitating subsequent lowering of the balance support plate 3 for maintenance and repair. A rotary limiting structure is arranged between the support plate 1 and the support rod 2, which is used for stable limiting and subsequent quick releasing of the support rod 2. The rotary limiting structure comprises a rotary top seat 81 rotatably installed at the center of the top surface of the support plate 1, a rotary bottom seat 82 rotatably installed at the center of the bottom surface of the support plate 1, and two strip-shaped clamping blocks 83 symmetrically fixed to the surface of the rotary top seat 81, and two strip-shaped clamping holes 21 corresponding to the strip-shaped clamping blocks 83 are formed in the side surface of the support rod 2, and the end of the strip-shaped clamping block 83 is screwed into one of the strip-shaped clamping holes 21, so as to stably support the support rod 2 and ensure the effective connection between the support rod 2 and the support plate 1, and two rotary support plates 84 are symmetrically fixed to the surface of the rotary bottom seat 82, and the rotary support plates 84 are rotated to the bottom surface of the support rod 2, so as to stably support the bottom surface of the support rod 2 and ensure the installation stability of the support rod 2 and the balance tray 3, and the rotary limiting structure further comprises a cylindrical shaft block 85 rotatably installed at the center of the inside of the support plate 1, the top end of the cylindrical shaft block 85 is fixed to the top surface of the support plate 1 and the rotary top seat 81, and the bottom end of the cylindrical shaft block 85 is fixed to the bottom surface of the support plate 1 and the rotary bottom seat 82, so that the rotary top seat 81 and the rotary bottom seat 82 can be fixed together through the cylindrical shaft block 85 and rotated synchronously. The bottom surface of the balance tray 3 is symmetrically welded and fixed with two bottom insertion blocks 33, the side surface of the support rod 2 is welded and fixed with a side insertion seat 22 corresponding to the bottom insertion block 33, and the bottom end of the bottom insertion block 33 is inserted into the inside of the side insertion seat 22, the balance tray 3 is attached to the support rod 2, and a clamping type connecting structure 9 is further arranged between the balance tray 3 and the side insertion seat 22.

[0017] In this embodiment, preferably, a plurality of installation grooves are formed in the inner wall of the bottom end of the rectangular sliding groove 31, and a plurality of rolling balls 32 are rotatably installed in the installation grooves, the top end of the rolling ball 32 is extended to the inside of the rectangular sliding groove 31, so as to effectively support the balance sliding seat 4 and reduce the frictional resistance when the balance sliding seat 4 slides through rolling friction.

[0018] In the embodiment, preferably, the rotating limiting structure further comprises a bottom groove 861 formed in the inner bottom end of the support rod 2, a spring A 862 and a telescopic clamping bead 863 installed in the bottom groove 861, and a circular clamping hole 864 formed in the surface of the rotating support plate 84. The telescopic clamping bead 863 is movably installed in the bottom groove 861 through the spring A 862, and the bottom end of the telescopic clamping bead 863 protrudes into the circular clamping hole 864 to stably limit the rotating support plate 84, preventing the rotating support plate 84, the rotating base 82 and the rotating top base 81 from rotating during daily use, thereby ensuring that the rotating support plate 84 can be stably supported on the bottom surface of the support rod 2 during daily use, and that the end of the strip-shaped clamping block 83 can be stably located in the strip-shaped clamping hole 21 to stably support the support rod 2, thereby ensuring the stability of the connection between the support rod 2 and the support plate 1. When subsequent maintenance of the balance support plate 3 and the balance sliding seat 4 is required, the rotating top base 81 is first rotated to rotate the cylindrical shaft block 85 with the rotating base 82, so that the end of the telescopic clamping bead 863 is gradually squeezed into the bottom groove 861 when the rotating support plate 84 rotates, thereby smoothly rotating and moving away the rotating support plate 84 from the bottom of the support rod 2, and the strip-shaped clamping block 83 is also rotated out of the strip-shaped clamping hole 21, so that the support rod 2 is no longer limited. At this time, the balance support plate 3 can be moved downward to separate the rack 41 from the shaft 61, and the balance support plate 3 can be lowered to the top of the support plate 1. At this time, the balance support plate 3 and the balance sliding seat 4 can be directly maintained, thereby improving the convenience of subsequent maintenance. After maintenance, the balance support plate 3 is raised to the original position again, and then the rotating top base 81 is rotated again to rotate the end of the strip-shaped clamping block 83 into the strip-shaped clamping hole 21, and the end of the rotating support plate 84 is rotated to the bottom surface of the support rod 2, thereby stably limiting the support rod 2. At the same time, the bottom end of the telescopic clamping bead 863 is clamped into the circular clamping hole 864 under the pushing of the spring A 862, thereby completing the stable support of the rotating support plate 84 on the support rod 2.

[0019] In the embodiment, preferably, the top end of the spring A 862 is fixed to the upper wall of the bottom groove 861, and the bottom end of the spring A 862 is fixed to the telescopic clamping bead 863.

[0020] In the embodiment, preferably, the side surface of the machine tool body 7 is provided with a first strip-shaped groove 71 corresponding to the strip-shaped clamping block 83 relative to the top of the support plate 1, so that the strip-shaped clamping block 83 has sufficient rotating space.

[0021] In the embodiment, preferably, the side surface of the machine tool body 7 is provided with a second strip-shaped groove 72 corresponding to the rotating support plate 84 relative to the bottom of the support plate 1, so that the rotating support plate 84 has sufficient rotating space.

[0022] In the embodiment, preferably, the clamping connection structure 9 comprises an L-shaped bottom clamping plate 91 movably mounted on the bottom surface of the balance supporting plate 3, a triangular clamping block 92 welded and fixed on the bottom end side surface of the L-shaped bottom clamping plate 91, and a rectangular clamping slot 93 opened on the side surface of the side socket 22, the triangular clamping block 92 is clamped into the rectangular clamping slot 93, thereby realizing the stable connection between the balance supporting plate 3 and the side socket 22, and completing the quick and stable connection between the balance supporting plate 3 and the supporting rod 2. The clamping connection structure 9 further comprises an upper sliding groove 94 opened on the bottom surface of the balance supporting plate 3, an upper sliding block 95 slidingly arranged in the upper sliding groove 94, and a spring B 96 arranged in the upper sliding groove 94 and located on one side of the upper sliding block 95. Under the abutting action of the spring B 96, the upper sliding block 95 can abut against the inner wall of the upper sliding groove 94 during daily use, and the bottom end of the L-shaped bottom clamping plate 91 can abut against the side surface of the side socket 22, so that the triangular clamping block 92 is stably clamped in the rectangular clamping slot 93, thereby ensuring the connection stability between the balance supporting plate 3 and the supporting rod 2. If the balance supporting plate 3 and the supporting rod 2 are to be disassembled subsequently, the rotating top seat 81 is first rotated, so that the strip-shaped clamping block 83 is rotated out of the strip-shaped clamping opening 21, and the rotating supporting plate 84 is rotated away from the bottom of the supporting rod 2. Then, the balance supporting plate 3 is moved downward to the lowest position, and then the L-shaped bottom clamping plate 91 is pulled sideways, so that the upper sliding block 95 is moved sideways and the spring B 96 is further compressed, until the triangular clamping block 92 is moved out of the rectangular clamping slot 93. At this time, the balance supporting plate 3 can be lifted, so that the bottom clamping block 33 is separated from the side socket 22, thereby realizing the quick disassembly of the balance supporting plate 3 and the supporting rod 2, and facilitating the subsequent disassembly and maintenance.

[0023] In the embodiment, preferably, the side surface of the upper sliding block 95 is fixed with a supporting guide rod 97, the supporting guide rod 97 passes through the spring B 96, and the end portion of the supporting guide rod 97 penetrates into the side surface of the balance supporting plate 3. When the upper sliding block 95 moves sideways, the supporting guide rod 97 can play a guiding and supporting role, and the supporting guide rod 97 can prevent the spring B 96 from deviating in the upper sliding groove 94.

[0024] Although the embodiments of the present application have been shown and described in detail (see the above detailed description), it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
