Abstract

The utility model provides a mounting structure of a main spindle box of a machine tool, which comprises the following components: the horizontal guide rail module is arranged on the beam module and comprises a front plate, a rear plate and a connecting plate, the front plate and the rear plate are arranged in parallel, the front plate and the rear plate are connected through the connecting plate, the spindle box module is connected with the front plate through a first screw, and the horizontal guide rail module is connected with the rear plate through a second screw. The saddle with the double-layer structure is used, so that the production efficiency can be improved, the hoisting correction of the geometric precision of the machine tool in the early stage is facilitated, and the operations such as the replacement of the guide rail or the detachment of the correction precision in the later stage are facilitated.

Description

Mounting structure of machine tool spindle box

Technical Field

The utility model relates to the field of machine tools, in particular to a mounting structure of a main spindle box of a machine tool.

Background

When a problem occurs in a machine tool, a great deal of time is often spent on assembly, disassembly and debugging. Fig. 1 shows a schematic diagram of a prior art mounting structure for a headstock of a machine tool. As shown in fig. 1, a headstock module 3 of a machine tool in the prior art is mounted on a horizontal guide rail module 4 of a beam module 1 through a saddle module 2, wherein the saddle module 2 has a single-layer structure, and connection screws between the saddle module 2 and the headstock module 3 and connection screws between the saddle module 2 and the horizontal guide rail module 4 are all located on the same mounting plate of the saddle module 2. Because the clearance between the saddle module 2 and the beam module 1 is very small, the connecting screw of the spindle box module 3 is inconvenient to detach, and the spindle box module 3 is difficult to detach quickly. If the headstock module 3 is to be removed, the headstock module 3 and the saddle module 2 need to be removed from the beam module 1 together, which is inconvenient for later maintenance of the equipment.

Disclosure of Invention

The utility model provides a mounting structure of a main spindle box of a machine tool, which aims to solve at least one technical problem.

In order to solve the above-described problems, as an aspect of the present utility model, there is provided a machine tool headstock mounting structure comprising: the horizontal guide rail module is arranged on the beam module and comprises a front plate, a rear plate and a connecting plate, the front plate and the rear plate are arranged in parallel, the front plate and the rear plate are connected through the connecting plate, the spindle box module is connected with the front plate through a first screw, and the horizontal guide rail module is connected with the rear plate through a second screw.

By adopting the technical scheme, the saddle with the double-layer structure can improve production efficiency, thereby being convenient for hoisting correction of the geometric precision of the machine tool in the early stage, and facilitating operations such as maintenance and replacement of guide rails in the later stage or correction precision disassembly.

Detailed Description

The following describes embodiments of the utility model in detail, but the utility model may be practiced in a variety of different ways, as defined and covered by the claims.

Referring to fig. 2 and 4-6, as an aspect of the present utility model, there is provided a mounting structure of a headstock of a machine tool, including: the novel horizontal guide rail type saddle comprises a cross beam module 1, a saddle module 2 and a main shaft box module 3, wherein a horizontal guide rail module 4 is arranged on the cross beam module 1, the saddle module 2 comprises a front plate 5, a rear plate 6 and a connecting plate 7, the front plate 5 and the rear plate 6 are arranged in parallel, the front plate 5 and the rear plate 6 are connected through the connecting plate 7, the main shaft box module 3 is connected with the front plate 5 through a first screw 8, and the horizontal guide rail module 4 is connected with the rear plate 6 through a second screw 9.

In the above technical solution, the saddle module 2 of the present utility model is formed in a double-layered structure by the front plate 5, the rear plate 6 and the connection plate 7, so that a sufficiently large space is formed between the front plate 5 and the rear plate 6. Thus, when the linear motor/rail fails and the headstock module 3 needs to be disassembled, a worker can conveniently disassemble the first screw 8 from the space between the front plate 5 and the rear plate 6 without disassembling the second screw 9 between the horizontal rail module 4 and the rear plate 6. In addition, under this kind of structure, also make things convenient for the manual work to debug when adjusting the relative position of headstock module 3 etc. and be convenient for earlier stage lathe precision installation and need adjust the cooperation.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
