Description

Technical Field

[0001] The utility model relates to the technical field of vertical machining centers, and particularly relates to a high-precision vertical machining center. Background Technique

[0002] A vertical machining center is a highly automated multi-functional numerical control machine tool that can perform various machining operations on workpieces. Its characteristic is that the spindle axis is vertically arranged with respect to the worktable, and it can complete various processes such as milling, boring, drilling, tapping, and cutting threads. The vertical machining center realizes the cutting machining of the workpiece through the relative movement of the rotation of the cutting tool and the feeding of the workpiece. The cutting tool is driven by the spindle to rotate at high speed, and the workpiece is linearly or rotationally fed through the worktable. The relative movement between the cutting tool and the workpiece generates a cutting force, thereby realizing the cutting machining of the workpiece.

[0003] For the guide rails on the existing vertical machining centers, since they are exposed to the outside for a long time, the lubricating oil on the surface of the guide rails will dry up. If the lubricating oil cannot be added in time, the dryness of the surface of the guide rails will cause the sliding mechanism to be easily blocked when sliding on the guide rails, resulting in low precision during the machining of the machining center. Therefore, we propose a high-precision vertical machining center to solve the problems raised above. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-precision vertical machining center to solve the problem that for the guide rails on the existing vertical machining centers, since they are exposed to the outside for a long time, the lubricating oil on the surface of the guide rails will dry up. If the lubricating oil cannot be added in time, the dryness of the surface of the guide rails will cause the sliding mechanism to be easily blocked when sliding on the guide rails, resulting in low precision during the machining of the machining center, which is mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-precision vertical machining center, including a column and a base, and the column is installed at the rear upper end of the base;

A saddle is arranged on the upper end of the base, and a sliding seat is arranged at the bottom of the saddle and is slidably engaged with the upper end of the first slide rail. Second slide rails are symmetrically arranged on both sides of the upper end of the saddle. A workbench is arranged above the saddle, and sliding seats are arranged on both sides of the bottom of the workbench and are slidably engaged and connected with the second slide rails. A spindle box is arranged at the front end of the column. Installation boxes are arranged outside the upper ends of the first slide rail and the second slide rail, and the installation boxes are respectively located at both ends of the sliding seats at the bottom of the saddle and both ends of the sliding seats at the bottom of the workbench. A top sponge is arranged at the upper end inside the installation box, and the top sponge is respectively attached to the upper ends of the first slide rail and the second slide rail. Side sponges are symmetrically arranged on both sides inside the installation box, and the side sponges are respectively located in the grooves on both sides of the first slide rail and the second slide rail.

[0008] Preferably, a movable plate is arranged at the upper end of the installation box. Connecting rods are symmetrically arranged on both sides of the bottom of the movable plate, and the connecting rods extend into the installation box. A pressing plate is arranged inside the installation box. The pressing plate is connected to the connecting rods, and the pressing plate is located above the top sponge.

[0009] Preferably, springs are arranged on the outer sides of the connecting rods, and the springs are located between the installation box and the movable plate.

[0010] Preferably, an oil injection port is arranged at the upper end of the installation box, and the oil injection port communicates with the inside of the installation box.

[0011] Preferably, a sealing plug is arranged at the upper end of the oil injection port, and the sealing plug is threadedly connected to the oil injection port.

[0012] Preferably, oil flow grooves are symmetrically arranged on both sides of the installation box, and the oil flow grooves connect the side sponges and the top sponges.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By arranging installation boxes outside the slide rails, the installation boxes are respectively arranged at both ends of the sliding seats at the bottom of the saddle and both ends of the sliding seats at the bottom of the workbench, so that when the saddle and the workbench move on the slide rails, the installation boxes can slide on the slide rails synchronously. Sponges are arranged at the upper end and both sides inside the installation boxes, and the sponges are attached to the upper ends of the slide rails and the grooves on both sides of the slide rails. Lubricating oil can be injected into the inside of the installation box through the oil injection port at the upper end of the installation box and immersed in the top sponge. The excess oil in the top sponge overflows and flows into the side sponges through the oil flow grooves, so that the slide rails can be lubricated every time they move, thereby ensuring the machining accuracy of the vertical machining center.

[0015] 2. By arranging a pressing plate at the upper end of the top sponge, connecting the pressing plate with a movable plate, pressing the movable plate can press down the pressing plate, squeezing the top sponge by the pressing plate, and extruding the lubricating oil in the top sponge, so that when the lubricating oil in the top sponge is insufficient, the lubricating oil in the sponge can be further extruded by squeezing.
