Description

Technical Field

[0001] The present application belongs to the field of CNC machining and relates to a high-strength CNC machine tool workbench. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program-controlled system that allows it to operate and process parts according to a pre-programmed program. CNC machine tools integrate mechanics, automation, computers, and microelectronics technologies to solve the problem of machining complex, precise, and small-batch parts. They are flexible and highly efficient automated machine tools.

[0003] The worktable of a CNC machine tool is the working surface for machining workpieces and is a key component of the machine. CNC machine tools exert great force on the worktable during machining, so high requirements are placed on the worktable's quality and stability.

[0004] Patent CN105750934A discloses a workbench of a CNC machine tool, including a secondary table plate and a main table plate installed on the secondary table plate, the main table plate and the secondary table plate are fixedly connected, the main table plate is made of hard metal material, and the secondary table plate is made of hard stone.

[0005] The above-mentioned workbench is composed of two types of table tops. On the one hand, the main table top made of hard metal material serves as the work surface to ensure the quality of the workbench. On the other hand, the secondary table top made of hard stone serves as the base to improve the rigidity, stability and anti-interference performance of the workbench.

[0006] However, the overall weight of the workbench is relatively large, which increases the energy consumption of the motor. Utility Model Content

[0007] In order to improve the strength of the workbench while reducing additional energy consumption, the present application provides a high-strength CNC machine tool workbench.

[0008] The present application provides a high-strength CNC machine tool workbench adopts the following technical solutions:

[0009] A high-strength CNC machine tool workbench includes a tabletop, the upper surface of the tabletop has an upper connecting portion for connecting to a workpiece fixture, the lower surface of the tabletop has a lower connecting portion for cooperating with a driving screw of a CNC machining center, and the lower surface of the tabletop also has a plurality of honeycomb-shaped reinforcing ribs.

[0010] By adopting the above technical solution, the workpiece fixture is fixed to the table through the upper connecting part, and the workpiece is fixed on the workpiece fixture. The lower plate surface of the table is connected to the driving screw of the CNC machining center through the lower connecting part. The table is driven by the driving screw to move the workpiece to the processing station of the CNC machining center. Since the lower plate surface of the table has honeycomb-shaped reinforcement ribs, the overall strength of the table can be improved. At the same time, since the honeycomb-shaped reinforcement ribs themselves have more weight-reducing holes, the additional energy consumption can be reduced.

[0011] Preferably, the honeycomb-shaped reinforcement ribs are hexagonal, and the reinforcement ribs are evenly distributed.

[0012] By adopting the above technical solution, the hexagonal reinforcement ribs have better strength and provide a larger weight reduction space, which reduces the overall weight of the workbench. The reinforcement ribs are evenly distributed, which can make the force more uniform everywhere and prevent local deformation from occurring easily.

[0013] Preferably, the upper connecting portion includes a connecting groove opened on the upper surface of the table top, and the lower surface of the table top has a reinforcing strip corresponding to the connecting groove one by one, and the reinforcing strip is located directly below the corresponding connecting groove.

[0014] By adopting the above technical solution, the table is connected to the workpiece fixture through the connecting groove, and the position of the workpiece fixture can be adjusted according to actual needs. The lower surface of the table has a reinforcing strip located below the connecting groove. Since the connecting groove of the table is subjected to greater force, the design of the reinforcing strip can improve the strength here and reduce the risk of deformation.

[0015] Preferably, the cross-section of the reinforcement strip is an isosceles trapezoid, and the reinforcement strips are spaced apart and evenly distributed.

[0016] By adopting the above technical solutions, the trapezoidal reinforcement bars can significantly enhance the load-bearing capacity of the structure because they can effectively resist stresses such as bending, shear, and torsion. The trapezoidal cross-section design allows for more efficient distribution of stress, thereby preventing the structure from deforming or damaging when subjected to external forces; the trapezoidal cross-section uses materials more efficiently than traditional rectangular or circular cross-sections. Because the trapezoidal cross-section is wider at the root and narrower at the top, more material can be provided where maximum strength is required, while reducing material use where less strength is not required; this design can significantly reduce material costs while maintaining the strength and stability of the structure.

[0017] Preferably, the lower surface of the table is also provided with a connecting seat for cooperating with the slide rail of the CNC machining center. There are two groups of connecting seats, each group of connecting seats includes a front seat body and a rear seat body distributed along the moving direction of the table, the front seat bodies in the two groups of connecting seats are connected by a front connecting plate, and the rear seat bodies in the two groups of connecting seats are connected by a rear connecting plate. The front connecting plate and the rear connecting plate divide the lower surface of the table into a front area, a middle area and a rear area, and the lower connecting part is arranged in the middle area of the lower surface of the table.

[0018] By adopting the above technical solution, the table top is provided with two sets of connecting seats, which can improve the stability of the table top when sliding. The design of the front connecting plate and the rear connecting plate can improve the overall strength of the table top.

[0019] Preferably, the six sides of the reinforcing rib in the middle area are arranged in the horizontal direction, and the lengths of the six sides are equal.

[0020] By adopting the above technical solution, the lengths of the sides of the reinforcing ribs are equal, the force is more evenly distributed, and the stability of the table is good.

[0021] Preferably, the reinforcing ribs at the front area and the rear area are distributed obliquely, and the height of the reinforcing ribs at the front area and the rear area gradually decreases from the edge of the table plate to the center of the table plate.

[0022] By adopting the above technical solution, the reinforcement ribs in the front and rear areas are distributed obliquely to optimize the bearing structure.

[0023] Preferably, the front end of the lower plate surface of the table plate has a V-shaped front connecting edge, and the lower surface of the front connecting edge is coplanar with the lower surface of the reinforcing rib in the front area. The rear end of the lower plate surface of the table plate has a V-shaped rear connecting edge, and the lower surface of the rear connecting edge is coplanar with the lower surface of the reinforcing rib in the rear area.

[0024] By adopting the above technical solution, the front connecting edge and the reinforcing ribs of the front area are arranged in the same plane, and the rear connecting edge and the reinforcing ribs of the rear area are arranged in the same plane, so the load-bearing is more stable.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The lower surface of the table has honeycomb-shaped reinforcement ribs, which can improve the overall strength of the table. At the same time, since the honeycomb-shaped reinforcement ribs themselves have more weight-reducing holes, they can reduce additional energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.
