Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a ground rail driving structure and an industrial equipment. Background Art

[0002] The floor rail type is a design form of the bed of mechanical equipment. Compared with the side-mounted travel axis and the hanging travel axis, its main feature is that it has stronger load-bearing capacity and stability. It can directly bear the weight of the table and materials. It is more suitable for extra-large tabletops and heavy-loaded mechanical equipment, especially for laser cutting machines, that is, floor rail laser cutting machines.

[0003] The existing floor rail equipment generally adopts double-drive on both sides or single-drive on one side. The drive installation part is a hinge structure, that is, one side of the drive installation is a hinge, and the other side is a spring elastic compensation structure. Although this drive arrangement can compensate for errors such as straightness and parallelism of the bed body and ensure good meshing of gears and racks, this drive method also has certain disadvantages. During the movement of the entire equipment along the bed, because one side is a hinge fixed end and the other side is a spring elastic compensation floating end, this will cause inconsistent meshing force between the gear and the rack during the forward and backward movement, which is prone to eccentric wear of the gear and rack, resulting in reduced accuracy or even damage to the equipment.

[0004] In addition, with the changes in market demand, the shipbuilding industry has an increasing demand for ultra-large-format floor-rail laser cutting machines. The mass of moving parts such as beams has doubled, and the required driving torque has also doubled. The upper limit of the commonly used rack specifications for floor-rail laser cutting machines is 3 modes. The above-mentioned single-sided drive method has to be replaced with a larger rack specification to ensure that it can carry a larger driving force. A larger rack specification means matching a larger heavy rail, which leads to a substantial increase in costs. Utility Model Content

[0005] Aiming at the problem that the accuracy of the floor rail driving structure of the current floor rail type equipment is easily reduced, the utility model provides a floor rail type driving structure with more balanced force.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a ground rail type driving structure, including a ground rail and a moving seat installed on the ground rail, and two sets of driving devices are arranged between the ground rail and the moving seat, and the two sets of driving devices are symmetrically arranged on both sides of the ground rail and the moving seat. In this solution, driving devices are arranged on both sides of the ground rail. When the moving seat moves, the two sets of driving devices are subjected to the same force, which avoids the problem of eccentric wear and improves the accuracy retention of the equipment during continuous use; at the same time, when the moving seat is stationary, the driving devices on both sides can provide a certain driving force in opposite directions to achieve clearance elimination and improve the operating accuracy of the equipment.

[0007] Preferably, the driving device includes a rack and pinion drive assembly, the rack is fixedly mounted on the side of the ground rail, the pinion drive assembly includes a drive motor, the drive motor is mounted on a moving seat, and a drive gear is provided on the output shaft of the drive motor, and the drive gear meshes with the rack on the corresponding side. By using a rack and pinion structure as a driving device and cooperating with the double-sided drive of the ground rail, a small-sized rack can be used to obtain a large driving force, thereby solving the problem of rising costs of replacing a single drive with a larger-sized rack heavy rail.

[0008] Preferably, the gear drive assembly further comprises a floating mount, the drive motor is fixedly mounted on the floating mount, the floating mount is slidably mounted on the moving seat via a guide rail assembly, the guide rail assembly is horizontally perpendicular to the ground rail, and an elastic compensation assembly is further provided between the floating mount and the moving seat. The elastic compensation assembly is provided in the meshing pressure direction of the gear rack to achieve the mechanical accuracy of the double-sided flexible compensation bed, thereby ensuring the accuracy and durability of the equipment.

[0009] Preferably, the gear drive assembly is provided with multiple groups along the extension direction of the ground rail, and the driving gears in the multiple gear drive assemblies are all meshed with the racks on the corresponding sides. Multiple groups of gear drive assemblies are used on both sides to improve the driving power.

[0010] Preferably, a supporting wheel is provided at the bottom of the movable seat, and the supporting wheel is in rolling contact with the top surface of the ground rail.

[0011] Preferably, the outer peripheral surface of the supporting wheel is a concave arc surface. When rolling on the ground rail, the horizontal error of the bed can be compensated, and the horizontal accuracy of the equipment can be further ensured.

[0012] Preferably, wheel assemblies are provided on both sides of the movable seat, and the wheel assemblies on both sides are in rolling contact with the two side surfaces of the ground rail respectively.

[0013] Preferably, the wheel assembly includes a straight shaft wheel assembly and an eccentric shaft wheel assembly, the eccentric shaft wheel assembly includes a connecting shaft and a wheel axle, the connecting shaft is eccentrically connected to the wheel axle, the connecting shaft is connected to the movable seat, an eccentric wheel is rotatably mounted on the wheel axle, and the outer peripheral surface of the eccentric wheel presses against the side of the ground rail. When the equipment is assembled, the straight shaft wheel assembly directly approaches one side of the ground rail as a positioning reference, and the other side uses the eccentric shaft to make the eccentric wheel clamp the other side of the ground rail.

[0014] Preferably, the elastic compensation component comprises a spring, one end of the spring is connected to the floating mounting seat, and the other end of the spring is connected to the moving seat.

[0015] On the other hand, the utility model also provides an industrial equipment, including a table top component, both sides of which are provided with the above-mentioned ground rail type driving structure, the ground rail is fixedly installed on the installation base, and the table top component is connected to the moving seat.

[0016] In addition, industrial equipment can also adopt single-sided dual drive, including a table top component, one side of the table top component is provided with the above-mentioned ground rail drive structure, the ground rail is fixedly installed on the installation base, and the table top component is connected to the moving seat; the other side of the table top component is installed on the installation base through a follow-up supporting device.

[0017] It can be seen from the above technical scheme that the advantages of the utility model are that the ground rail driving structure of the scheme is provided with driving devices on both sides of the ground rail. When the moving seat moves, the two sets of driving devices are subjected to the same force, avoiding the problem of eccentric wear and improving the accuracy retention of the equipment during continuous use; when the moving seat is stationary, it can also provide a certain driving force in opposite directions through the driving devices on both sides to achieve gap elimination and improve the operation accuracy of the equipment; elastic compensation components are designed on both sides of the moving seat to achieve the mechanical accuracy of the double-sided flexible compensation bed and ensure the accuracy and durability of the equipment; through the assembly process design, an eccentric wheel is adopted to improve the assembly accuracy.
