Description

Technical Field

[0001] The invention relates to the technical field of machining centers, in particular to a multi-station multi-axis machining center. Background Art

[0002] Machining center is a machining center machine tool, also called CNC numerical control machine tool, or machining center for short. Machining center machine tools are usually composed of control systems, servo systems, detection systems, mechanical transmission systems and other auxiliary systems. They are high-efficiency automated machine tools suitable for processing workpieces with complex shapes. Machining center is a highly mechatronic machine tool that can continuously complete multiple processes such as drilling, boring, milling, and reaming, thereby greatly reducing the workpiece clamping time, measurement, machine tool adjustment and other auxiliary process time. It has good economic benefits for processing parts with complex shapes, high precision requirements, and frequent variety changes.

[0003] When existing machining center machines process workpieces of uncertain styles or different materials, the clamping mechanism needs to be replaced manually to adapt to the clamping method of the workpiece to be processed. For example, when dealing with workpieces of materials such as rubber, they are usually fixed by clamping the edges of the workpiece to prevent the workpiece from deforming and affecting the processing quality. However, most clamping mechanisms do not have the ability to clamp the edges, and usually require manual hand-held tools such as spring clamps to manually fix the rubber workpiece on the load-bearing platform. The operation is very troublesome, wastes labor, reduces the efficiency of workpiece processing, and indirectly increases production costs. Summary of the invention

[0032] Among them, a first square groove 717 is horizontally opened on the first support rod 715, and first guide grooves 718 are horizontally opened on both sides of the inner wall of the first square groove 717.

The second guide groove 725 is slidably connected to the sliding block 721, and a screw 726 is fixedly connected to the bottom of the long strip 723.

[0034] It should be noted that: Figure 4-8 As shown, when the translation block 74 moves in the rectangular through hole 72 , the sliding block 721 , to which one end of the sliding rod 719 extending out of the bottom of the translation block 74 is fixedly connected, moves in the same direction along the second guide groove 725 in the second square groove 724 .

[0035] Among them, a plurality of threaded sleeves 727 are rotatably connected to the bottom of the inner wall of the box body 71, and the threaded sleeves 727 are threadedly connected to the screw rod 726. A first gear 728 is fixedly connected to the threaded sleeve 727, and a ring 729 is sleeved on the outer periphery of the first gear 728. A plurality of vertical rods 730 are arranged on the outer side of the ring 729. The bottom of the vertical rod 730 is fixedly connected to the bottom of the inner wall of the box body 71, and a shaft rod 731 is rotatably connected to the side wall of the vertical rod 730. The shaft rod 731 is slidably connected to the ring 729.

The first tooth groove 732 is meshed with the first gear 728.

[0036] It should be noted that: Figure 4 , Figure 6 As shown, the outer wall of the threaded sleeve 727 is provided with a platform for supporting the ring 729, and the top of the platform fits in with the bottom of the ring 729 to prevent the ring 729 from being suspended in the air due to lack of support points, causing the ring 729 to shake, and the vertical rod 730 limits the ring 729 by rotating the connected shaft 731. When the ring 729 rotates, the shaft 731 fits in with the top of the ring 729 and rotates to prevent the ring 729 from swinging during the rotation process, resulting in loose meshing of the first tooth groove 732 and the first gear 728, thereby affecting the transmission effect of the ring 729.

[0037] An electric telescopic rod 734 is provided on one side of the second tooth groove 733 , the bottom of the electric telescopic rod 734 is fixedly connected to the bottom of the inner wall of the box body 71 , and a rack 735 is fixedly connected to the output end of the electric telescopic rod 734 , and the rack 735 is meshed with the second tooth groove 733 .

[0038] Among them, a rotating shaft 736 is rotatably connected to the bottom of the inner wall of the box body 71, and the top of the rotating shaft 736 is rotatably connected to the top of the inner wall of the box body 71. A plurality of second connecting rods 737 are fixedly connected to the rotating shaft 736, and one end of the second connecting rod 737 is fixedly connected to a guide rail 738. A sliding column 739 is slidably connected in the guide rail 738, and the top of the sliding column 739 is fixedly connected to the bottom of the translation block 74.

[0039] Among them, a second gear 740 is fixedly connected to the rotating shaft 736, a driving motor 741 is arranged on one side of the second gear 740, the bottom of the driving motor 741 is fixedly connected to the bottom of the inner wall of the box body 71, and a third gear 742 is fixedly connected to the output end of the driving motor 741, and the third gear 742 is meshed with the second gear 740.

[0040] Embodiment 1: Figure 1-8 As shown, in this embodiment, the workpiece is first placed on the top of the box body 71, and the driving motor 741 fixedly connected to the bottom of the inner wall of the box body 71 is started to rotate the third gear 742, and the second gear 740 meshed with the third gear 742 rotates the rotating shaft 736, thereby driving the multiple second connecting rods 737 fixedly connected to the rotating shaft 736 to rotate, and then the guide slide rail 738 fixedly connected at one end of the second connecting rod 737 rotates, so that the sliding column 739 slidingly connected in the guide slide rail 738 moves in the guide slide rail 738, so that the translation block 74 fixedly connected to the top of the sliding column 739 moves toward the workpiece through the slider 75 in the rectangular through hole 72 along the slide grooves 73 on both sides of the rectangular through hole 72, thereby driving the C-shaped clamping block 76 fixedly connected to the top of the translation block 74 to move toward the workpiece, and then the side wall of the C-shaped clamping block 76 and the side wall of the clamping plate 711 contact the outer wall of the workpiece, so that the workpiece is fixed on the top of the box body 71, so as to facilitate the tool head at the front end of the output tool holder 5 to process the workpiece.

[0041] It should be noted that: when the workpiece needs to be stretched and clamped from the internal cavity to the outside, the translation block 74 must first be moved toward the top center of the box body 71 through the above operation until the side wall of the translation block 74 hits the inner wall of the rectangular through hole 72, thereby driving the C-shaped clamp block 76 and the arc block 713 fixedly connected to one side of the C-shaped clamp block 76 to move within the diameter range of the workpiece inner cavity, and the workpiece is placed on the outside of the arc block 713 so that the arc block 713 is in the inner cavity of the workpiece. The drive motor 741 is started to move the arc block 713 away from the top center of the box body 71, so that the side wall of the arc block 713 hits the inner wall of the workpiece, thereby achieving the purpose of fixing the workpiece on the top of the box body 71.

[0042] When the workpiece is made of a deformable material such as rubber and needs to be fixed by clamping the edge of the workpiece, the workpiece is first placed on the top of the box body 71, and the translation block 74 is moved to the edge of the workpiece. At the same time, the C-shaped clamping block 76 is kept at a certain distance from the edge of the workpiece to prevent the C-shaped clamping block 76 from contacting the edge of the workpiece and deforming the workpiece, and the electric telescopic rod 734 fixedly connected to the bottom of the inner wall of the box body 71 is started to push the rack 735 to move, and the ring 729 is rotated through the second tooth groove 733 engaged with the rack 735, and the first tooth groove 732 of the ring 729 is engaged with the first gear 728 fixedly connected to the threaded sleeve 727. When the ring 729 rotates, the first gear 728 drives the threaded sleeve 727 to rotate through the first tooth groove 732, so that the screw 726 threadedly connected to the threaded sleeve 727 enters the inner cavity of the threaded sleeve 727, and then the screw 726 drives the long strip 723 fixedly connected to the top of the screw 726 along the fixed rod 72 When the cam 720 is in the state of being rotated, the second stopper 714 is pressed downwardly, and the second stopper 716 ...2 is pressed downwardly, and the second stopper 712 is pressed downwardly, and the first stopper 712 is pressed downwardly, and the first stopper 712 is pressed downwardly, and the first stopper 712 is pressed downwardly, and the first stopper

[0043] From the above, it can be seen that the machining center moves the translation block 74 in the rectangular through hole 72, driving the C-shaped clamp block 76, the clamp plate 711 and the arc block 713 to clamp the workpiece externally or to open and clamp the inner cavity. Through the cooperation between the clamp plate 711 and the top of the box body 71, the edges of the workpiece made of rubber and other materials are clamped. The above method improves the clamping adaptability of the device to workpieces of different material types and specifications, avoids the need to manually replace clamping tools due to the diversity of workpieces, and the trouble of manual clamping, saves labor, thereby improving the production efficiency of the workpiece and indirectly reducing production costs.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
