Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and particularly relates to a high-precision numerical control machine tool with adjustable clearance. Background Technique

[0002] A high-precision numerical control machine tool is short for a numerically controlled machine tool. The basic components of a numerical control machine tool include a processing program carrier, a numerical control device, a servo drive device, a machine tool main body, and other auxiliary devices. Among them, the machine tool mainframe is the main body of the numerical control machine tool, which includes mechanical components such as a bed, a base, a column, a crossbeam, a slide, a workbench, a spindle box, a feed mechanism, a tool rest, and an automatic tool changer. A Y-axis ball screw nut seat is installed under the slide installed on the guide rail part of the machine tool main body, and the servo motor drives the screw to rotate to push the slide to slide linearly on the guide rail.

[0003] However, there is mostly a fixed clearance between the slide and the guide rail of the existing numerical control machine tool. The clearance between the slide and the guide rail becomes larger after long-term wear, which affects the machining accuracy. Moreover, it is difficult and costly to replace the guide rail after wear. In order to solve the deficiencies of the existing technology, we propose a high-precision numerical control machine tool with adjustable clearance. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a high-precision numerical control machine tool with adjustable clearance, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A high-precision numerical control machine tool with adjustable clearance, including a machine tool main body. Guide rails are symmetrically and detachably installed on the top of the machine tool main body. A slide is slidably connected to the outside of the guide rail. One side of the top of the slide is threadedly connected with a first adjusting bolt. One end of the first adjusting bolt is threadedly connected with a first push plate. A first wear plate is detachably installed at the bottom of the first push plate. A first chute is opened at the top inner wall of the slide. The outside of the first wear plate is slidably connected to the inside of the first chute opened in the slide. A second chute is opened at the bottom inner wall of the slide. A second wear plate is slidably connected to the inside of the second chute opened in the slide. A corrugated metal elastic sheet abuts against the bottom of the second wear plate. The bottom of the corrugated metal elastic sheet abuts against the bottom inner wall of the second chute opened in the slide. A third chute is opened at one side inner wall of the slide. A limiting plate is slidably connected to the inside of the third chute opened in the slide. A second push plate is detachably installed on one side of the limiting plate. A first jackscrew is rotatably connected to one side of the second push plate.

[0007] Preferably, a second jackscrew is threadedly connected to the top of the slide. One end of the second jackscrew is rotatably connected to a movable plate. One end of the movable plate abuts against one side of the top of the second push plate.

[0008] Preferably, one side of the sliding seat is threadedly connected to one end of the first set screw, and the outer side of the second push plate is slidably connected to the inside of the third sliding groove formed in the sliding seat.

[0009] Preferably, a storage groove is formed at the top of the sliding seat, a baffle is slidably connected to the inside of the storage groove formed in the sliding seat, and the bottom of the baffle abuts against the top of the first adjusting bolt.

[0012] Advantages

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the first wear plate provided and the sliding plate on the guide rail are used as wear compensation between the sliding seat and the guide rail, and the sliding gap between the sliding seat and the guide rail is adjusted to the original size, ensuring the machining accuracy of the machine tool body. At the same time, the corrugated metal elastic sheet pushes the second wear plate to keep in contact with one side of the bottom of the guide rail under the action of its own elastic force, maintaining the sliding gap of the sliding seat on the guide rail, and the sliding gap of the sliding seat on the guide rail is stable.

[0015] 2. In the utility model, the limiting plate provided is used as compensation for side wear between the sliding seat and the guide rail. Then, the second set screw is screwed to push the movable plate to support on the side of the second push plate, so that the limiting plate supported by the second push plate is more stable, and the sliding of the sliding seat on the guide rail is more stable.

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 - 4 shown, a high-precision numerical control machine tool with adjustable clearance includes a machine tool main body 1. Guide rails 2 are symmetrically and detachably installed on the top of the machine tool main body 1. A slide seat 3 is slidably connected to the outside of the guide rails 2. When the slide seat 3 wears due to long-term sliding on the guide rails 2, the sliding clearance between the slide seat 3 and the guide rails 2 becomes larger. By turning the first adjustment bolt 4 to push the first push plate 5 to drive the first wear plate 6 to supplement the sliding clearance between the slide seat 3 and the guide rails 2, and using the first wear plate 6 and the slide plate 15 on the guide rails 2 as the wear compensation between the slide seat 3 and the guide rails 2, the sliding clearance between the slide seat 3 and the guide rails 2 is adjusted to the original size, ensuring the machining accuracy of the machine tool main body 1. The machining accuracy of the machine tool main body 1 is higher, and the high-precision machine tool main body 1 is more convenient to use. At the same time, the corrugated metal elastic sheet 8 in the second chute opened by the slide seat 3 pushes the second wear plate 7 under the action of its own elastic force, and the second wear plate 7 remains in contact with one side of the bottom of the guide rail 2, so as to maintain the sliding clearance between the slide seat 3 and the guide rails 2, and the sliding clearance between the slide seat 3 and the guide rails 2 is stable.

[0023] As Figures 1 - 4 shown, a third chute is opened on one side of the inner wall of the slide seat 3. A limiting plate 9 is slidably connected inside the third chute opened by the slide seat 3. A second push plate 10 is detachably installed on one side of the limiting plate 9. A first jackscrew 11 is rotatably connected to one side of the second push plate 10. By turning the first jackscrew 11 to push the second push plate 10 to drive the limiting plate 9 as the compensation for the side wear between the slide seat 3 and the guide rails 2, and then turning the second jackscrew 12 to push the movable plate 13 to support on the side of the second push plate 10, so that the limiting plate 9 supported by the second push plate 10 is more stable, and the sliding of the slide seat 3 on the guide rails 2 is more stable.

[0024] Working principle

[0025] It should be noted that the present utility model is a high-precision numerical control machine tool with adjustable clearance. When in use, first take out the baffle 14 from the storage groove provided in the slide base 3. After the slide base 3 and the guide rail 2 are worn after a period of use, turn the first adjusting bolt 4. The first adjusting bolt 4 pushes the first push plate 5 through the thread, and the first push plate 5 pushes the first wear plate 6 to tightly abut against the slide plate 15, thereby adjusting the sliding clearance between the slide base 3 and the guide rail 2. At the same time, the corrugated metal elastic sheet 8 in the second chute provided in the slide base 3 pushes the second wear plate 7 under the action of its own elastic force, and the second wear plate 7 remains in contact with one side of the bottom of the guide rail 2, thereby maintaining the sliding clearance of the slide base 3 on the guide rail 2. The first wear plate 6, the slide plate 15 and the second wear plate 7 are used as wear compensation between the slide base 3 and the guide rail 2 to achieve the purpose of adjusting the sliding clearance between the slide base 3 and the guide rail 2.

[0026] When wear occurs on the side between the slide base 3 and the guide rail 2, turn the first set screw 11 to push the second push plate 10 through the thread on the slide base 3 to drive the limiting plate 9 to slide out of the third chute provided in the slide base 3. The limiting plate 9 serves as compensation for the side wear between the slide base 3 and the guide rail 2, thereby maintaining the sliding clearance between the side surfaces of the slide base 3 and the guide rail 2. Then turn the second set screw 12. The second set screw 12 pushes the movable plate 13 through the thread on the slide base 3, and the movable plate 13 moves downward until it abuts against one side of the top of the moved second push plate 10. The movable plate 13 and the second set screw 12 cooperate as the side support of the second push plate 10. The second push plate 10 supports the limiting plate 9 to support on the side of the guide rail 2. When the guide rail 2 presses the limiting plate 9, the limiting plate 9 pushes the second push plate 10 to push the first set screw 11 and the movable plate 13. One side of the movable plate 13 is supported on one side of the inner wall of the third chute provided in the slide base 3. The movable plate 13 serves as the side compensation support of the second push plate 10, so that the limiting plate 9 supported by the second push plate 10 is more stable, achieving the purpose of stably supporting the limiting plate 9.
