Abstract

The utility model discloses a follow-up chip removal device which is composed of a support (1) and a chip scraping plate (3) which can be turned unidirectionally. The chip scraping plate (3) is in a shape similar to the section of a chip collection groove on a machine tool body, and the upper edge of the chip scraping plate (3) is hinged with the support (1) through a pin shaft (2). The follow-up chip removal device is arranged on the lateral side of a movable work bench of a machine tool, and the chip scraping plate is arranged in the chip collection groove of the machine tool body. When the work bench reciprocates left and right, chips in the chip collection groove can be scraped to a chip removal port to be removed repeatedly by the chip scraping plate. The follow-up chip removal device is simple in structure, low in manufacturing cost, convenient to install and maintain and good in chip removal effect.

Description

Follow-up chip removal device

technical field

The utility model relates to a chip removal device, in particular to a follow-up type chip removal device used on a large numerically controlled machine tool.

Background technique

At present, the chip removal devices used for large CNC machine tools are all screw-type chip removal devices. There are two of these chip removal devices, one is a left-handed screw rod and the other is a right-handed screw rod. The two screw rods are installed separately. In the chip pockets on both sides of the machine table. During chip removal, they are driven by the motor to rotate, and the chips in the chip collection grooves on both sides are transported to the chip discharge port at the end of the machine tool in the same direction. The minimum manufacturing cost of each pair of this chip conveyor is not less than 2,000 yuan, and the power of the used motor is about 370 watts.

Contents of the invention

The purpose of the utility model is to provide an economical and applicable follow-up chip removal device to reduce the cost of large numerically controlled machine tools.

The technical solution to achieve the above purpose is: a follow-up chip removal device, which is composed of a bracket and a one-way flipping scraper plate. Hinged with bracket.

The lower end of the bracket extends to the back of the scraping plate, and the edge in contact with the back of the scraping plate is a vertical edge, and the extension part is equivalent to a stopper on the back of the scraping plate.

The device is installed on the side of the moving table of the machine tool, and the scraping plate is in the chip collecting groove of the bed. Along with the left and right reciprocating side movement of the workbench, the scraper board will scrape the chips in the chip collection groove to the chip discharge port again and again to be discharged. The device has simple structure, very low manufacturing cost, convenient installation and maintenance, and good chip removal effect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 to 5, the follow-up chip removal device of the utility model is composed of a bracket 1 and a scraper plate 3. The upper edge of the scraper plate 3 is hinged with the bracket 1 through a pin shaft 2 and forms a one-way flip. The angle is within the range of 90°, the lower end of the bracket 1 extends to the back of the scraping plate 3, and the edge in contact with the back of the scraping plate 3 is a vertical edge, and this extension part is equivalent to the stopper on the back of the scraping plate 3; The shape of the plate surface of the plate 3 is similar to the cross-sectional shape of the chip flute 5 on the machine bed 6, which is generally arc-shaped (as shown in Figure 1), and can also be V-shaped.

As shown in Figure 4, the device is installed on the side of the machine tool motion table 4, and the scraper plate 3 is located in the chip collecting groove 5 of the machine bed 6 and has a proper gap. If both sides of the machine tool bed 6 have chip collecting grooves 5, then respectively install a copy device on both sides of the workbench 4, and ensure that the turning directions of the scraping plates 3 on both sides are the same.

As shown in Figure 5, due to the long bed of the large CNC machine tool, more than two sets of the device can be arranged on both sides of the workbench 4 for timely and thorough chip removal. Assuming that the chip outlet is located at the left end of the bed, after the device is installed, when the workbench 4 moves to the right, the scraper plate 3 will automatically turn to the left at a certain angle under the action of the chips in the groove, and slide over the chips; When the workbench 4 moves to the left, the chip removal plate 3 will hang down naturally by its own weight and be close to the downward extension of the support 1. As the workbench 4 continues to move to the left, the chip removal plate 3 will collect the chips. The chips in the groove 5 are scraped and pushed toward the chip outlet. Along with the reciprocating side-to-side movement of the workbench 4, the scraper plate 3 scrapes the chips in the chip collecting groove 5 to the chip discharge port one after another, and then removes the chips.

Claims (2)

1. trailing type chip removal device, it is characterized in that: it is comprised of the bits plates (3) of scraping of support (1) and unidirectional upset, described to scrape bits plates (3) similar with the section configuration of crumb loading groove on the bed piece, and the upper edge of scraping bits plates (3) is hinged by bearing pin (2) and support (1).

2. trailing type chip removal device according to claim 1 is characterized in that: the lower end of described support (1) extends to the described back side of scraping bits plates (3), is perpendicular edge with scraping bits contacted limit, plate (3) back side.
