Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and more specifically to a cantilever heavy-duty triaxial truss with a reinforced structure. Background Technology

[0002] The cantilevered 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, transmission mechanism, and 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. When the three axes are performing translational work, a guide shaft is usually set to enhance the stability of the movement process. The guide shaft is generally made of high-hardness, high-precision metal materials such as high-quality carbon steel or alloy steel that has undergone quenching treatment. Its surface is precision machined to have extremely high straightness and smoothness, thus ensuring that the slider it mates with can slide stably and smoothly. In terms of installation, the guide shaft is usually set parallel to the lead screw, and its two ends are installed on the frame or support structure of the equipment with the help of bearing seats or other fixing devices. This installation method can ensure the installation accuracy of the guide shaft, maintain its parallelism with the lead screw, and ensure that the two are on the same plane, thereby effectively avoiding the generation of additional friction, preventing the moving parts from jamming, and ensuring the stable operation of the triaxial structure.

[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 existing triaxial equipment technology, the main function of the slide rail and fixed bar is to ensure the smooth sliding of the slider. However, under heavy load conditions, this structure faces many challenges: due to the heavy load, the center of gravity of the equipment shifts, and the friction between the slider and the slide rail / fixed bar increases significantly. This not only significantly increases the load on the drive system, but also accelerates the wear of the slide rail and fixed bar surfaces, resulting in reduced motion efficiency and a significant shortening of the equipment's service life. At the same time, the stress generated by the heavy load can also cause slight deformation of the slide rail and fixed bar. This deformation can interfere with the predetermined motion trajectory of the slider, resulting in a significant decrease in the positioning accuracy of the equipment. In precision parts processing, electronic component assembly, and other operations with extremely high precision requirements, the above problems can easily lead to product quality defects, resulting in an increased defect rate and even the production of scrap. Utility Model Content

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

[0006] The utility model provides the following technical solution: a cantilever heavy-duty triaxial truss with a reinforced structure, including an X-axis motion component, a Y-axis motion component movably mounted on the X-axis motion component, a Z-axis motion component movably mounted on the Y-axis motion component, and a cantilever fixedly mounted on the side of the Z-axis motion component. A reinforced component is installed on the side of the Y-axis motion component away from the cantilever. The reinforced component slides synchronously with the cantilever in the lateral and longitudinal directions. The end of the reinforced component away from the Y-axis motion component is mounted on the cantilever.

[0007] Furthermore, the reinforcement component includes two fixing plates fixedly connected to both sides of the rear surface of the Y-axis motion component. Two limiting rods are fixedly connected between the two fixing plates. Support columns are slidably connected to the outer surfaces of the limiting rods. Two limiting rods are fixedly connected to the top of the support columns. Two sliding seats are slidably connected to the outer surfaces of the limiting rods. Connecting columns are rotatably connected to the surfaces of the sliding seats. A locking column is fixedly connected to the top center of the cantilever. The connecting column is inserted into the outside of the locking column. A positioning bolt is threaded onto the outer surface of the locking column, and the end face of the positioning bolt abuts against the surface of the locking column.

[0008] Furthermore, a slot is provided at the bottom of the connecting column, a pad is fixedly connected to the inner wall of the slot, and the end face of the positioning bolt extends into the interior of the slot.

[0009] Furthermore, the locking pin is inserted into the inside of the slot, and the surface of the locking pin away from the positioning bolt abuts against the surface of the pad.

[0010] Furthermore, the support column has a transversely extending groove that matches the limiting rod, and the sliding seat has a longitudinally extending limiting groove that matches the limiting rod.

[0011] Furthermore, the length of the limiting rod is greater than the height at which the cantilever can slide longitudinally, and the surface of the pad is provided with protrusions at equal intervals.

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

[0013] 1. This utility model, by installing a reinforcing component on the side of the Y-axis motion assembly away from the cantilever, and having the reinforcing component slide synchronously with the cantilever in the lateral and longitudinal directions and one end mounted on the cantilever, allows the cantilever to withstand longitudinal heavy loads without relying solely on the support between the Y-axis and Z-axis motion assemblies. When the cantilever is under heavy load, the support column of the reinforcing component slides on the limiting rod, and the sliding seat slides on the limiting rod, effectively dispersing the gravity on the cantilever, sharing the pressure of the Y-axis and Z-axis motion assemblies, enhancing the stability of the overall structure, improving the load-bearing capacity of the cantilever, and thus extending the service life of the equipment.

[0014] 2. In this utility model, the reinforcing component is tightly connected to the cantilever. During the movement of the cantilever, the limiting rod and the limiting bar precisely limit the support column and the sliding seat respectively, ensuring that the distance between the cantilever and the support column is always equal. This allows the cantilever to maintain a stable movement trajectory when sliding laterally and longitudinally, reducing the tilting of the cantilever due to heavy loads, effectively avoiding interference with the movement trajectory of the slider due to structural deformation, thereby improving the positioning accuracy of the equipment, meeting the needs of high-precision operation scenarios such as precision parts processing and electronic component assembly, and reducing the product defect rate.

[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 1-4This 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 cantilever heavy-duty triaxial truss with a reinforced structure includes an X-axis motion component 1, a Y-axis motion component 2 movably mounted on the X-axis motion component 1, a Z-axis motion component 3 movably mounted on the Y-axis motion component 2, and a cantilever 4 fixedly mounted on the side of the Z-axis motion component 3. A reinforced component 5 is mounted on the side of the Y-axis motion component 2 away from the cantilever 4. The reinforced component 5 slides synchronously with the cantilever 4 in the lateral and longitudinal directions. One end of the reinforced component 5 away from the Y-axis motion component 2 is mounted on the cantilever 4.

[0023] The three-axis linkage structure between the X-axis motion component 1, the Y-axis motion component 2, and the Z-axis motion component 3 is existing technology and has the same motion principle and structure as the utility model patent with announcement number CN220312227U.

[0024] In this implementation scheme, when the cantilever 4 is subjected to a longitudinal heavy load, the reinforcement component 5 can disperse the gravity of the cantilever 4, share the pressure of the Y-axis motion component 2 and the Z-axis motion component 3, enhance the overall structural stability, improve the load-bearing strength of the cantilever 4, extend the service life of the equipment, and at the same time ensure that the cantilever 4 maintains a stable motion trajectory when sliding laterally and longitudinally, thereby improving the positioning accuracy of the equipment.

[0025] Specifically, the reinforcement component 5 includes two fixing plates 51 fixedly connected to both sides of the rear surface of the Y-axis motion component 2. Two limiting rods 52 are fixedly connected between the two fixing plates 51. Support columns 53 are slidably connected to the outer surface of the limiting rods 52. Two limiting rods 54 are fixedly connected to the top of the support columns 53. Two sliding seats 55 are slidably connected to the outer surface of the limiting rods 54. Connecting columns 56 are rotatably connected to the surface of the sliding seats 55. A locking column 57 is fixedly connected to the top center of the cantilever 4. The connecting column 56 is inserted into the outside of the locking column 57. A positioning bolt 58 is threaded on the outer surface of the locking column 57. The end face of the positioning bolt 58 abuts against the surface of the locking column 57.

[0026] In this embodiment, the fixed plate 51 and the limiting rod 52 provide a stable sliding track for the support column 53, so that the support column 53 can stably share the weight when the cantilever 4 moves. The limiting rod 54 and the sliding seat 55 cooperate to ensure the stability of the longitudinal movement of the connecting column 56 and the cantilever 4. The positioning bolt 58 can firmly fix the connecting column 56 and the locking column 57, ensuring that the reinforcement component 5 and the cantilever 4 can be quickly assembled and will not loosen during the operation of the equipment, thus maintaining the reinforcement and stability effect.

[0027] Specifically, a slot 561 is provided at the bottom of the connecting post 56, and a pad 562 is fixedly connected to the inner wall of the slot 561. The end face of the positioning bolt 58 extends into the interior of the slot 561.

[0028] In this embodiment, the slot 561 facilitates the insertion of the locking post 57, achieving initial positioning of the connecting post 56 and the cantilever 4. The pad 562 increases the contact area with the locking post 57, allowing the pressure applied by the positioning bolt 58 to be transmitted more evenly, enhancing the stability of the connection. At the same time, it protects the surface of the locking post 57, preventing wear caused by the direct action of the positioning bolt 58. The positioning bolt 58 extends into the slot 561, further enhancing the fastening effect and preventing the connecting post 56 and the locking post 57 from rotating relative to each other or separating.

[0029] Specifically, the locking pin 57 is inserted into the inside of the slot 561, and the surface of the locking pin 57 away from the positioning bolt 58 abuts against the surface of the pad 562.

[0030] In this embodiment, this connection method ensures that the connecting column 56 and the cantilever 4 are tightly connected, guaranteeing the effective transmission of force. The pad 562 increases friction and provides support, ensuring that the clamping column 57 can stably transmit the force to the connecting column 56 when subjected to external force, and then to the reinforcement component 5, thereby improving the reliability and stability of the overall structure.

[0031] Specifically, the support column 53 has a horizontally penetrating groove that matches the limiting rod 52, and the sliding seat 55 has a longitudinally penetrating limiting groove that matches the limiting rod 54.

[0032] In this embodiment, the slide groove matches the limiting rod 52 to ensure that the support column 53 can only slide laterally along the limiting rod 52, restricting its direction of movement and ensuring that the support column 53 maintains a stable lateral position when sharing the weight of the cantilever 4. The limiting groove matches the limiting rod 54 to ensure that the sliding seat 55 can only slide longitudinally, accurately controlling the longitudinal movement trajectory of the connecting column 56 and the cantilever 4, avoiding deviation or shaking, and improving the accuracy and stability of the equipment movement.

[0033] Specifically, the length of the limiting rod 54 is greater than the height at which the cantilever 4 can slide longitudinally, and the surface of the pad 562 is provided with protrusions at equal intervals.

[0034] In this embodiment, the limiting rod 54 is relatively long, which ensures that the sliding seat 55 always slides on the limiting rod 54 throughout the entire longitudinal movement range of the cantilever 4, and will not derail. It continuously provides stable longitudinal support and guidance for the cantilever 4. The protrusions on the surface of the pad 562 increase the friction between the pad and the locking post 57, further preventing relative sliding between the locking post 57 and the pad 562, improving the reliability of the connection, and ensuring the stability of the connection between the reinforcing component 5 and the cantilever 4.

[0035] The working principle and usage process of this utility model are as follows: During installation, slide the support column 53 on the limiting rod 52 until it is flush with the cantilever 4. At this time, rotate the connecting column 56 to insert the locking column 57 into the slot 561. Then, slide the cantilever 4 upward to its limit position through the Z-axis motion component 3. Then, by sliding the locking column 57 to the position of the connecting column 56, the distance between the sliding seat 55 and the support column 53 should be greater than the length of the cantilever 4 sliding downward to its limit. Then, tighten the fixing bolt 58 with a wrench. The abutment between the fixing bolt 58 and the locking column 57 makes the surface of the locking column 57 tightly adhere to the pad. The surface of plate 562 reinforces the connection between the reinforcing component 5 and the cantilever 4. When the cantilever 4 slides laterally, the support column 53 slides synchronously on the limiting rod 52. When the cantilever 4 slides longitudinally, the cantilever 4 drives the connecting column 56 to slide, and the sliding seat 55 slides longitudinally on the outer surface of the limiting rod 54. No matter how the cantilever 4 moves, the distance between the cantilever 4 and the support column 53 remains equal. By setting the reinforcing component 5, it can be ensured that when the cantilever 4 is subjected to longitudinal heavy load, it does not only rely on the support between the Y-axis motion component 2 and the Z-axis motion component 3, thereby improving the load-bearing strength of the cantilever 4 and extending its service life.

[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.
