Description

Technical Field

[0001] The utility model relates to the technical field of machine tool ram, in particular to a numerically controlled gantry machine tool ram which is convenient for maintenance. Background Technique

[0002] A gantry machine tool, also known as a gantry machining center, is a numerically controlled machine tool with high precision, high speed and multiple functions. It mainly consists of a base, a cross beam, a gantry, a workbench, a spindle box and other parts. Its structural feature is that the gantry spans above the workbench to form a stable frame structure, which can withstand large cutting forces and vibrations. Among them, the ram is a key mechanical component, which plays an important role in the operation of the machine tool. Its maintenance is crucial for ensuring the normal operation of the machine tool and extending its service life. At present, the maintenance of the ram mainly includes cleaning and lubrication, which are usually carried out manually. And due to the structural characteristics of the ram, its operation is rather inconvenient. Therefore, it is necessary to design a numerically controlled gantry machine tool ram which is convenient for maintenance to solve the problem. Summary of the Invention

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to provide a numerically controlled gantry machine tool ram which is convenient for maintenance.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A numerically controlled gantry machine tool ram which is convenient for maintenance, comprising a main body. A driving motor is fixedly installed on one side of the main body, and the output shaft of the driving motor is connected with a lead screw through the main body. A moving block is connected to the outside of the lead screw through a thread, and a support seat is fixedly installed at the bottom of the moving block. A maintenance part is fixedly installed at the bottom of the support seat, and a connecting plate is connected and installed at the bottom of the maintenance part. A first protection plate is connected to one side of the main body through screws, and a second protection plate is connected to one side of the support seat through screws;

[0006] A storage oil box is slidably connected inside the maintenance part, and a jacking plate is slidably connected inside the storage oil box. A push rod motor is arranged inside the maintenance part, and the output shaft of the push rod motor is connected with a push plate. A collecting cavity is arranged inside the maintenance part. An annular cavity is arranged inside the moving block, and the collecting cavity is connected with the annular cavity. An oil outlet is opened on the inner side of the annular cavity.

[0007] Preferably, the outside of the support seat is designed with a C-shaped structure, and the first protection plate and the second protection plate are in the same direction, which can not only stably support the equipment connected by the connecting plate, but also does not affect disassembly and assembly, so as to clean the interior.

[0008] Preferably, a moving groove adapted to the support seat is opened at the bottom of the main body, and a sealing gasket is laid inside the moving groove, reducing the possibility of dust entering and extending the time required for maintenance.

[0009] Preferably, a slide rail is fixedly installed on the outer side of the jacking plate, and a chute adapted to the slide rail is provided in the oil storage box. There are four groups of push rod motors, which are symmetrically distributed. The top of the push plate is connected to the bottom of the jacking plate, so as to ensure the stability of the jacking plate when it rises and avoid tilting.

[0010] Preferably, there are four oil outlets, which are distributed in an annular array and are provided with sealing rings, so that the grease can be stably applied to the outer side of the moving block.

[0011] The beneficial effects of the present utility model are as follows:

[0012] Grease can be stored in the oil storage box in advance. During the operation of the ram, the push rod motor is used to push the jacking plate to make the grease enter the surrounding cavity and be automatically applied to the outer side of the lead screw without manual operation. While the equipment is stably supported by the support base, the internal lead screw can be cleaned by disassembling the first protective plate and the second protective plate. The operation is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

A moving block 4 is connected to the outside of the lead screw 3 by a thread, and a support seat 5 is fixedly installed at the bottom of the moving block 4. A moving groove adapted to the support seat 5 is opened at the bottom of the main body 1, and a sealing gasket is laid in the moving groove to reduce the possibility of dust entering and extend the time required for maintenance. A maintenance part 6 is fixedly installed at the bottom of the support seat 5, and a connecting plate 7 is connected and installed at the bottom of the maintenance part 6. A first protective plate 8 is connected by screws on one side of the main body 1, and a second protective plate 9 is connected by screws on one side of the support seat 5. The outside of the support seat 5 is designed with a C-shaped structure, and the first protective plate 8 and the second protective plate 9 are in the same direction, which can not only stably support the equipment connected by the connecting plate 7, but also does not affect disassembly and assembly, so as to clean the inside.
