Technical Field

The invention relates to the technical field of numerical control machine tools, in particular to a geometric precision adjusting device for a machine tool and an adjusting method thereof.

Background

In general, when a linear rail ram is installed, the bearing edge of the linear rail is tightly attached to the sliding seat leaning surface, and the pitching angle of the ram is in a proper range completely depending on the precision guarantee of the sliding seat leaning surface. The defect of doing so is that the work load is very big in the middle of the debugging of later stage and maintenance, needs to dismantle four line rails, ram, slide apron, the transmission case at ram top, cable etc. has increased the maintenance cost in the intangible.

Disclosure of Invention

The invention aims to provide a geometric precision adjusting device for a machine tool and an adjusting method thereof, aiming at the defects and the shortcomings of the prior art.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a geometric accuracy adjusting device for lathe, includes the ram, cup joint the slide on the ram, the slide adopts line rail and slider to carry out sliding connection with the four corners of ram, and its innovation point lies in: the side between slider and the slide sets up the adjusting block, the lower extreme of adjusting block sets up the adjustment fixed block, set up first locking screw and slider fixed connection on the adjustment fixed block, set up second locking screw and adjusting block fixed connection.

Further, the thickness of the adjusting block is adjusted according to the pitch angle.

The adjusting method of the geometric precision adjusting device for the machine tool has the innovation points that: when the ram pitching angle changes, the adjusting block is pulled out by only loosening the first locking screw and then loosening the second locking screw, the adjusting fixing block is taken out, the thickness of the adjusting block is adjusted by calculating the required pitching angle, and then the adjusting block is installed again and locked.

Furthermore, the sliding blocks and the sliding seats at the four corners are respectively adjusted in sequence by an adjusting method.

After adopting the structure, the invention has the beneficial effects that:

the invention has simple structure and convenient use; according to the invention, the adjusting block is pulled out, the required pitching angle is calculated, the thickness of the adjusting block is adjusted, and then the adjusting block is installed again and locked, so that the process of disassembling a plurality of parts is omitted, the precision of other parts of the machine tool is not influenced, and meanwhile, the maintenance cost is saved.

Description of reference numerals:

the device comprises a ram 1, a slide seat 2, a slide block 3, an adjusting block 4, an adjusting fixing block 5, a first locking screw 6 and a second locking screw 7.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

Example 1

Referring to fig. 1-3, a geometric accuracy adjusting device for a machine tool comprises a ram 1, a slide carriage 2 is sleeved on the ram 1, the slide carriage 2 is in sliding connection with four corners of the ram 1 through a linear rail and a slide block 3, an adjusting block 4 is arranged on a side surface between the slide block 3 and the slide carriage 2, an adjusting fixed block 5 is arranged at the lower end of the adjusting block 4, a first locking screw 6 is arranged on the adjusting fixed block 5 and is fixedly connected with the slide block 3, and a second locking screw 7 is arranged and is fixedly connected with the adjusting block 5. Specifically, when adjustment is performed, the first locking screw 6 is firstly loosened, the second locking screw 7 is loosened, the adjusting fixing block 5 is taken out, the adjusting block 4 is pulled out, the thickness of the adjusting block 4 is adjusted by calculating the required pitch angle, and then the adjusting block is installed again and locked; calculating the pitch angle is prior art and is not described in detail in this application.

In this embodiment, the thickness of the adjustment block 4 is adjusted according to the pitch angle.

Example 2

When the elevation angle of a ram changes, the device only needs to loosen a first locking screw and then loosen a second locking screw, take out an adjusting fixed block, pull out the adjusting block, adjust the thickness of the adjusting block by calculating the needed elevation angle, and then re-load and lock the adjusting block.

In this embodiment, the sliders and the sliders at the four corners are respectively adjusted in sequence by an adjustment method.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
