Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, and particularly relates to an inclined bed turning and milling machine tool. Background Technique

[0002] The inclined bed turning and milling compound machine tool is an automated machine tool with an inclined bed. The plane where the two guide rails of the inclined bed turning and milling compound machine tool intersect with the ground plane forms an inclined plane, and the angles are 30°, 45°, 60°, and 75°. The bed of the inclined bed turning and milling compound machine tool is in the shape of a right triangle. Obviously, in the case of the same guide rail width, the X-axis carriage of the inclined bed is longer than that of the flat bed. The practical significance applied to the lathe is that more tool positions can be arranged, so that a multi-station turret or a power east turret can be equipped, and it has the characteristics of high precision and high efficiency.

[0003] According to the Chinese utility model patent with the existing publication number CN214867301U, it records an inclined bed turning and milling compound machine tool, including an inclined bed, a spindle assembly arranged on the left side of the upper surface of the inclined bed, and a tailstock guide rail arranged on the front side of the right part of the inclined bed. A tailstock assembly matching the tailstock guide rail is arranged above the inclined bed. A saddle guide rail is arranged on the rear side of the right part of the inclined bed. A Y-axis saddle assembly matching the saddle guide rail is arranged above the inclined bed. An X-axis saddle assembly matching the Y-axis saddle assembly is arranged above the Y-axis saddle assembly. A turret assembly matching the X-axis saddle assembly is arranged on the X-axis saddle assembly.

[0004] In the existing inclined bed turning and milling compound machine tools on the market, the Y-axis saddle assembly is movably installed at a certain angle on the inclined surface of the X-axis saddle. Since the contact surface between the X-axis saddle and the Y-axis saddle is an inclined structure, most of the weight of the Y-axis saddle is pressed on the lower edge of the guide rail, resulting in a smaller force-bearing area of the guide rail on the X-axis saddle and greater wear. Therefore, in view of these current situations, there is an urgent need to develop an inclined bed turning and milling machine tool to meet the actual use requirements. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an inclined bed turning and milling machine tool to solve the above defects.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions:

[0007] An inclined bed turning and milling machine tool includes a lathe casting, a rotating main shaft, and a machining tool holder. The middle of the lathe casting is provided with an x-axis casting. The front end face of the x-axis casting is an upwardly inclined mounting end face. An y-axis casting is also provided on the mounting end face. The axial direction of the y-axis casting is perpendicular to the axial direction of the x-axis casting. The machining tool holder is arranged above the y-axis casting. The middle of the x-axis casting is provided with a horizontally arranged first guide rail. The y-axis casting is horizontally movably connected to the middle of the x-axis casting through the first guide rail. The two side edges of the mounting end face are provided with horizontally arranged guide rail platforms. The first guide rail is horizontally arranged on the guide rail platforms. And the bottom end face of the y-axis casting is provided with a downwardly protruding connecting boss. The connecting boss is movably arranged on the guide rail platforms through the first guide rail.

[0008] In the above description, as a further solution, a spindle casting for installing the rotating main shaft is provided at the top of one end of the lathe casting. The rotating main shaft is rotatably arranged inside the spindle casting.

[0009] In the above description, as a further solution, a sliding plate is provided in the middle of the y-axis casting. The machining tool holder is fixedly connected to the top end face of the sliding plate. A second guide rail is provided between the sliding plate and the y-axis casting. The sliding plate is movably connected to the top end face of the y-axis casting through the second guide rail.

[0010] In the above description, as a further solution, an x-axis lead screw drive mechanism is provided inside the x-axis casting. The y-axis casting can move horizontally along one side of the rotating main shaft through the x-axis lead screw drive mechanism.

[0011] In the above description, as a further solution, a y-axis lead screw drive mechanism is provided inside the y-axis casting. The sliding plate can move obliquely along the axial direction of the y-axis casting through the y-axis lead screw drive mechanism.

[0012] In the above description, as a further solution, both the x-axis lead screw drive mechanism and the y-axis lead screw drive mechanism are composed of a lead screw transmission part and a motor control part.

[0013] The beneficial effects produced by the present utility model are as follows:

[0014] For an inclined bed turning and milling machine tool of the present application, two guide rail platforms parallel to the gravity direction are machined on the mounting end face of the traditional x-axis casting. At the same time, a connecting boss matching the guide rail platforms is cast outward at the bottom end face of the y-axis casting, so that the first guide rail can be installed parallel between the guide rail platforms and the connecting boss. When the y-axis casting is installed on the mounting end face, the gravity of the y-axis casting can be effectively and evenly distributed to the guide rail platforms through the guide rail platforms and the connecting boss, effectively increasing the force-bearing area of the guide rail on the X-axis saddle and reducing its wear and tear.

A second guide rail 41 is provided between the slide plate 7 and the Y-axis casting 4. The slide plate 7 is movably connected to the top end face of the Y-axis casting 4 through the second guide rail 41. The machining tool holder 5 is arranged above the Y-axis casting 4. A horizontally arranged first guide rail 31 is provided in the middle of the X-axis casting 3. The Y-axis casting 4 is horizontally movably connected to the middle of the X-axis casting 3 through the first guide rail 31;
