Description

Technical Field

[0001] The utility model relates to the technical field of guide rail seats, and more specifically to a guide rail seat for a numerically controlled machine tool. Background Art

[0002] CNC machine tools are one of the most widely used machining machines. They are mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. One of the indispensable parts of CNC machine tools is the guide seat. The guide seat cooperates with the screw slide to move the cutter head to the processing position to perform milling on the workpiece.

[0003] The guide rail seat used in existing machine tools will be exposed in the milling space to ensure the normal operation of the screw slide. During milling, coolant and milling chips will splash onto the surface of the guide rail seat, causing jamming at the connection position between the guide rail seat and the screw slide, affecting the smooth movement of the screw slide. In view of this, we propose a guide rail seat for CNC machine tools. Utility Model Content

The direct fit between each other can reduce the gap at the contact position. When the screw slide 2 moves, the baffle 5 can push the debris back and forth in the upper channel 15 to avoid entering the gap between the screw slide 2 and the upper channel 15, and between the screw slide 2 and the guide bar 14. At the same time, a notch 16 is provided at the edge of the upper channel 15 of the main body 12, and the debris will be separated from the upper channel 15 from the notch 16 to avoid accumulation in the upper channel 15, thereby ensuring the cleanliness of the sliding position of the screw slide 2 and ensuring smooth horizontal sliding.

[0023] Reference Figure 2The top edge of the main body 12 is convexly formed with a support bar, and the top surface of the support bar contacts the screw slide 2, which can increase the contact area, thereby ensuring the stability of the support, ensuring that when the milling assembly 4 is installed on the screw slide 2 and the dead weight increases, the linear sliding can be carried out smoothly, and a plurality of notches 16 are provided, and the plurality of notches 16 are equidistantly arranged on the support bar along the extension direction of the guide bar 14. The notches 16 can be opened at a distance from one end, and the debris can be pushed down the upper channel 15 by moving a short distance to avoid the debris on the screw slide. When table 2 reciprocates for a small distance, too much debris accumulates at the position of the upper channel 15, and the end of the notch 16 is designed to be inclined downward in the direction away from the guide bar 14, that is, the lower edge of the notch 16 is inclined, and as it tilts downward away from the upper channel 15, an inclined guide surface can be formed to ensure that the connection position between the notch 16 and the upper channel 15 is the highest point of the notch 16 and the lowest point of the upper channel 15, which can ensure that the debris in the upper channel 15 can be completely discharged to both sides through the notch 16, ensuring smooth waste discharge.

[0024] Reference Figure 3 A wear-resistant block is arranged on the top of the support bar. The wear-resistant block adopts a rectangular structure and fits with the top surface of the support bar. Moreover, the wear-resistant block is arranged between the notches. When the screw slide 2 moves, the top surface of the wear-resistant block slides in contact with the ground of the slide. This can effectively reduce friction resistance while ensuring that the screw slide 2 is stably supported at multiple points, and ensure stable long-term movement.

[0025] Reference Figure 3 The vertical side wall of the main body 12 is located at the lower edge of the notch 16 and extends upward to form a lower channel 17. The left and right sides of the main body 12 protrude upward in an inclined manner, and the protruding vertices are away from each other on the left and right sides to form a V-shaped lower channel 17. The lower channel 17 can carry debris that falls out of the notch 16 and guide it to the front and rear sides to avoid the debris discharged from the notch 16 still accumulating on the left and right sides of the main body 12, and no secondary cleaning is required. The setting of the lower channel 17, the main body 12 is located at the port position of the lower channel 17 and is equipped with a chip removal bucket 13 that cooperates with the lower channel 17 and is conductive, so that debris can be guided to the position of the chip removal bucket 13, and convex ribs are formed on the left and right sides of the main body 12, which can improve the structural strength of the main body 12. After the end frames 11 are installed at the front and rear ends of the main body 12, the end frames 11 are directly connected to the mounting platform below, and the main body 12 can be set overhead, which is convenient for cleaning the space below the main body 12 and subsequent maintenance is more convenient.

[0026] Reference Figure 3A scraper 18 is slidably installed in the lower channel 17. The scraper 18 includes an upper and lower part. The upper part is a vertical plate-like structure, which is fixedly connected to the vertical side wall of the slide, and the lower part of the scraper 18 is a triangular prism, which is used to fit the V-shaped inner wall of the lower channel 17. The slide moves back and forth, which can drive the scraper 18 to push the debris in the lower channel 17 back and forth. In addition, a slot is provided on the side of the scraper 18 facing the scraper 18 for the scraper 18 to pass freely. When the slide moves to the front and rear dead points, the triangular prism at the lower part of the scraper 18 can extend into the chip bucket 13, which can ensure that the chips and coolant are completely pushed into the chip bucket 13 for centralized collection.

[0027] Reference Figure 1 When in use, I improve the flexibility of movement. A screw slide 2 3 is installed on the upper part of the screw slide 1 2, which can be driven with three degrees of freedom. In addition, a milling component 4 is installed in the middle part of the screw slide 2 3. The milling component 4 is arranged vertically and can drive the cutter head to rotate for milling processing. It should be noted that only the guide seat 1 located at the bottom layer is easy to contact the chips, so it is preferred to use a guide seat 1 with a notch 16 and a scraper 18. The upper guide seat 1 can be optional to reduce manufacturing costs.

[0028] Reference Figure 4 The chip removal bucket 13 is opened upward and adopts a bucket-shaped structure. Openings are set on the upper part and the side away from the milling component 4. When the debris is collected in the lower channel 17, the debris will be concentrated and guided to the side away from the milling component 4 for collection. The chip removal bucket 13 is designed to extend to the side away from the milling component 4, and the height of the chip removal bucket 13 gradually decreases as it moves away from the milling component 4. Under the action of gravity, the debris in the chip removal bucket 13 can be discharged smoothly, ensuring conduction during use and facilitating subsequent cleaning.
