Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and more specifically to a flexibly adjustable cantilever heavy-duty three-axis truss. Background Technology

[0002] The cantilever heavy-duty triaxial structure is a commonly used mechanical structure in industrial equipment, covering three motion axes: X, Y, and Z. Each axis of this structure is equipped with a drive unit, a transmission mechanism, and a guide rail system. The drive unit often uses a servo motor to provide power for the axis's movement; the transmission mechanism includes types such as ball screws and gear racks.

[0003] A search revealed that utility model patent CN220312227U discloses a heavy-duty cantilever three-axis truss mechanism, which includes multiple supports. The top of the multiple supports is fixedly connected to a crossbeam. The top of the multiple crossbeams is symmetrically provided with two mounting plates. An X-axis motor is fixedly installed on the top of each of the two mounting plates. A cantilever is fixedly connected to the top of each of the two mounting plates. A movable seat is provided on one side of the outer surface of each of the two cantilevers.

[0004] In the three-axis truss mechanism in this patent or in the existing three-axis equipment technology, when the cantilever three-axis equipment is under heavy load, the center of gravity of the cantilever will shift due to the heavy load. As a result, the bottom support truss will be subjected to a large tensile force on the side closest to the cantilever. The large tensile force will cause the support truss to tilt and deform. Under long-term action, it may lead to local yielding of the truss or even plastic deformation, affecting the stability and geometric accuracy of the entire structure. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a flexible adjustable cantilever heavy-duty triaxial truss to solve the problems existing in the background art.

[0006] The utility model provides the following technical solution: a flexibly adjustable cantilever heavy-duty three-axis truss, including a support truss, an X-axis movable component mounted on the support truss, a Y-axis movable component movably connected to the X-axis movable component, and a Z-axis movable component movably connected to the Y-axis movable component. Sliding grooves are provided through both sides of the support truss, and locking holes are equidistantly provided on the sides of the support truss. Support components are installed on both sides of the support truss. The support components are longitudinally slidably connected to the outside of the support truss through the sliding grooves. There are two support components, located directly below the Y-axis movable component on both sides.

[0007] Furthermore, the support assembly includes a rod inserted into the slide groove. A side plate is fixedly connected to the outer surface of the rod. A top column is fixedly connected to the top of the side plate. There are two top columns. A locking rod is fixedly connected to the opposite face of the two top columns. A support column is rotatably connected to the surface of the side plate. A sliding seat is rotatably connected to the end of the support column away from the side plate. A positioning rod is inserted through the interior of the sliding seat. A base is fixedly connected to the end face of the positioning rod. A bearing is fixedly installed inside the base. A bolt is fixedly connected to the inner ring of the bearing. The outer surface of the bolt is threaded to the center of the interior of the sliding seat.

[0008] Furthermore, the card hole is arc-shaped, and the diameter of the card rod is smaller than the opening diameter of the card hole.

[0009] Furthermore, the base is U-shaped, and the sliding seat is slidably connected to the surface of the base via a positioning rod. A threaded hole matching the bearing is provided through the center of the sliding seat.

[0010] Furthermore, the sliding seat is L-shaped, and a square groove is provided on the top of the sliding seat. The support column is rotatably connected to the inside of the square groove by a positioning pin.

[0011] Furthermore, the insert rod passes through the slide groove, and both ends of the insert rod extend to the outer surface of the support truss, and the surface of the side plate is rotatably connected to the outside of the support truss.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model provides longitudinally sliding support components on both sides of the support truss, and the support components are located on both sides directly below the Y-axis movable component. When the cantilever triaxial equipment is subjected to heavy loads, causing the center of gravity to shift and the support truss near the cantilever to be subjected to large tensile force, the support components can provide additional support force for the support truss. By adjusting the position of the support components and fixing them with the cooperation of the clamping rod and the clamping hole, the tensile force is effectively distributed, reducing the tilting deformation of the support truss and avoiding the occurrence of local yielding or plastic deformation of the truss under long-term stress, which greatly enhances the stability of the entire structure.

[0014] 2. The structural design of the support component of this utility model makes it highly flexible. The insertion rod and the sliding groove cooperate to achieve longitudinal sliding, the side plate can rotate, and the sliding seat can slide laterally on the "U"-shaped base through the positioning rod. Furthermore, the position can be further adjusted through the cooperation of bolts and bearings. This allows the support component to be flexibly installed and adjusted according to different installation site spatial layouts, equipment cantilever lengths, center of gravity positions, and other actual installation scenarios and requirements. Whether in a narrow workshop or a special production environment with high precision requirements, the support component can be easily installed and adjusted, enhancing the applicability of the equipment and reducing installation and use costs.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] A flexibly adjustable cantilever heavy-duty three-axis truss includes a support truss 1, an X-axis movable component 2 mounted on the support truss 1, a Y-axis movable component 3 movably connected to the X-axis movable component 2, and a Z-axis movable component 4 movably connected to the Y-axis movable component 3. Slide grooves 5 are provided through both sides of the support truss 1, and locking holes 6 are provided at equal intervals on the sides of the support truss 1. Support components 7 are installed on both sides of the support truss 1. The support components 7 are longitudinally slidably connected to the outside of the support truss 1 through the slide grooves 5. There are two support components 7, which are located on both sides directly below the Y-axis movable component 3.

[0023] The three-axis linkage structure between the X-axis moving component 2, the Y-axis moving component 3, and the Z-axis moving component 4 is the same as the motion principle and structure in the utility model patent with announcement number CN220312227U.

[0024] In this embodiment, when the cantilevered three-axis equipment is subjected to heavy loads, causing the center of gravity to shift and the support truss 1 to be subjected to a large tensile force on the side near the cantilever, the support components 7 located on both sides directly below the Y-axis movable component 3 can provide additional support force for the support truss 1. Through the slide groove 5, the support component 7 can slide longitudinally, making it easy to adjust the height position according to actual needs. Then, it is fixed by using the clamping bar 74 and the clamping hole 6 to effectively share the tensile force, reduce the occurrence of tilting deformation of the support truss 1, avoid local yielding or plastic deformation of the truss under long-term stress, and enhance the stability of the entire structure.

[0025] Specifically, the support assembly 7 includes a rod 71 inserted into the slide groove 5. A side plate 72 is fixedly connected to the outer surface of the rod 71. A top post 73 is fixedly connected to the top of the side plate 72. There are two top posts 73. A locking rod 74 is fixedly connected to the opposite face of the two top posts 73. A support post 75 is rotatably connected to the surface of the side plate 72. A sliding seat 76 is rotatably connected to the end of the support post 75 away from the side plate 72. A positioning rod 77 is inserted through the interior of the sliding seat 76. A base 78 is fixedly connected to the end face of the positioning rod 77. A bearing 79 is fixedly installed inside the base 78. A bolt 710 is fixedly connected to the inner ring of the bearing 79. The outer surface of the bolt 710 is threadedly connected to the center of the interior of the sliding seat 76.

[0026] In this embodiment, the insert rod 71 cooperates with the slide groove 5, allowing the support assembly 7 to slide longitudinally along the support truss 1 for easy height adjustment. The side plate 72 can move with the insert rod 71 and rotate relative to the support truss 1, increasing the flexibility of adjustment. The top column 73 and the locking rod 74 are used to cooperate with the locking hole 6 to fix the position of the support assembly 7. The two ends of the support column 75 are rotatably connected to the side plate 72 and the sliding seat 76 respectively, allowing the sliding seat 76 to be adjusted at multiple angles. The sliding seat 76 slides on the base 78 through the positioning rod 77, allowing for lateral position adjustment. Combined with the cooperation of the bolt 710 and the bearing 79, the position of the support assembly 7 can be adjusted more precisely to adapt to different installation sites, equipment cantilever lengths, center of gravity, and other actual scenarios, thereby enhancing the applicability of the equipment and reducing installation and usage costs.

[0027] Specifically, the locator 6 is arc-shaped, and the diameter of the locator 74 is smaller than the opening of the locator 6.

[0028] In this embodiment, the arc-shaped locking hole 6 cooperates with the locking rod 74, whose diameter is smaller than its opening. During the adjustment of the position of the support component 7, the locking rod 74 can be inserted into and disengaged from the locking hole 6 more smoothly. When the locking rod 74 is inserted into the locking hole 6, due to the arc-shaped structure of the locking hole 6, the locking rod 74 can fit better with the inner wall of the locking hole 6, increasing the contact area, improving the stability of the fixation, ensuring that the support component 7 is firmly fixed on the support truss 1, effectively playing a supporting role, and sharing the tensile force on the support truss 1.

[0029] Specifically, the base 78 is U-shaped, and the sliding seat 76 is slidably connected to the surface of the base 78 via the positioning rod 77. A threaded hole matching the bearing 79 is opened through the center of the sliding seat 76.

[0030] In this embodiment, the "U"-shaped base 78 provides a stable sliding track for the sliding seat 76, making the sliding seat 76 slide more smoothly and reliably on the surface of the base 78 via the positioning rod 77. This facilitates precise adjustment of the lateral position of the support assembly 7. The threaded hole inside the sliding seat 76 that matches the bearing 79, along with the bolt 710, allows for further fine-tuning after the lateral position has been adjusted. It also prevents the sliding seat 76 from sliding accidentally during equipment operation, ensuring the stability of the position of the support assembly 7 and thus stably providing support force to the support truss 1.

[0031] Specifically, the sliding seat 76 is L-shaped, and a square groove is provided on the top of the sliding seat 76. The support column 75 is rotatably connected inside the square groove through a positioning pin.

[0032] In this embodiment, the "L"-shaped sliding seat 76 facilitates connection with other components, and the square groove on its top provides a reliable rotating connection structure for the support column 75. The support column 75 rotates in the square groove through the positioning pin, allowing the support column 75 to flexibly change its angle, thereby driving the side plate 72 and the insert rod 71 and other components to adjust their positions to adapt to different installation environments and equipment center of gravity distribution, thereby enhancing the flexibility of the support assembly 7 in adjustment and its adaptability to different working conditions.

[0033] Specifically, the insert rod 71 passes through the slide groove 5, and both ends of the insert rod 71 extend to the outer surface of the support truss 1, and the surface of the side plate 72 is rotatably connected to the outside of the support truss 1.

[0034] In this embodiment, the insert rod 71 passes through the slide groove 5 and extends out of the outer surface of the support truss 1 at both ends, which can effectively limit the sliding range of the insert rod 71 in the slide groove 5, prevent it from coming out of the slide groove 5, and ensure the reliability of the connection between the support assembly 7 and the support truss 1. The side plate 72 is rotatably connected to the outside of the support truss 1, so that the support assembly 7 can be adjusted by rotating the side plate 72 on the basis of longitudinal sliding, which makes it easy to accurately insert the locking rod 74 into the locking hole 6. At the same time, it can better adapt to the needs of different installation sites and equipment layouts, and improve the flexibility and applicability of the entire device.

[0035] The working principle and usage process of this utility model are as follows: In use, after fixing the support truss 1 to the designated position with bolts, the base 78 is also fixed to the designated position. When adjusting the position of the base 78, the base 78 drives the insert rod 71 to slide longitudinally within the slide groove 5 via the support column 75 and side plate 72. After adjusting the base 78 to the appropriate position, it is fixed with bolts. By rotating the side plate 72, the locking rod 74 slides towards the locking hole 6, and the insert rod 71 slides upward within the slide groove 5. At this point, the locking rod 74 needs to be engaged with the nearest locking hole 6. When the nearest locking hole 6 is above the locking rod 74, by rotating the insert rod 71 counterclockwise, the sliding seat 76 slides towards the support truss 1. The side plate 72 is slid upward by the support column 75, and the locking rod 74 is tightly locked inside the locking hole 6. When the nearest locking hole 6 is below the locking rod 74, the insert rod 71 is rotated in the opposite direction by the wrench, so that the sliding seat 76 slides away from the support truss 1. At this time, the support column 75 drives the side plate 72 to slide downward, and the insert rod 71 slides downward inside the slide groove 5 until the locking rod 74 is locked inside the locking hole 6. Then the insert rod 71 is rotated in the opposite direction, so that the surface of the locking rod 74 is tightly pressed against the inner wall of the locking hole 6. At this time, the support and reinforcement of the support truss 1 is completed. Moreover, the sliding seat 76 can slide laterally and the side plate 72 can slide longitudinally, so that the support component 7 can be used flexibly according to the actual installation scenario and requirements, which enhances its applicability.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
