Description

one

The invention relates to equipment for processing pipe grooves, namely devices for deburring the ends of cylindrical products.

A device for removing burrs from cylindrical parts is known, comprising a single piece nodach assembly and a deburring mechanism, which is shaped like a driving profiled disk, partially surrounded by a yoke and equipped on the periphery with paired support rollers and with non-displaced cutter along the copy.

However, the known device does not provide high-quality deburring, since the number of revolutions of the part per operating cycle is limited, due to which it is impossible to work with small feeds of the cutter for one revolution of the part; it has considerable dimensions and is difficult to manufacture.

The purpose of the invention is to reduce the size of the device and improve the quality of machining parts.

To this end, the deburring mechanism is implemented in the form of a swing sector with support rollers for receiving parts, which is installed with the possibility of reciprocating movement relative to the drive roller rotating the part in the same plane with it, and the tool holder is rotary.

FIG. 1 shows a general view of the device; in fig. 2, 3 and 4 are the working positions of the deburr mehkapism.

The deburring device consists of a piece feeding unit, which includes tray 1 and cutter 2, and a mechanism for removing zazsentsy. The deburring mechanism is made in the form of a drive roller 3 mounted on a drive shaft. Opposite the roller 3 there is a sector 4, on which are mounted two supporting rollers 5 and 6, bearing on ball bearings. Tray 7 for machined parts is installed under rollers 5 and 6. The tool is mounted on the holder 8 and can be rotated on the axis 9. Sector 4 from the profile cam of the camshaft 10 receives back and forward movements in the horizontal direction. In addition, the sector is made rotary PA axis 11 from the wedge 12 and the roller 13, located in the lower part of the sector.

Spring 14 presses the sector to the wedge. To compensate for some difference in the diameter of the workpiece (within the size tolerance), the device for moving the sector's drive is equipped with a compensator (not shown).

The proposed device works as follows.

The drive is turned on (not shown in the drawing) of the machine, from which the rotary roller 3 is rotated. Parts from tray 1 with a cutter 2 are individually fed into the working position. At this point, the cam of the camshaft 10 through the roller 13, incident on the wedge 12, feeds and turns sector 4 to the left. With the help of a cam mounted on the holder, the tool 8 is rotated. In the resulting gap between the upper follower 5 and the master 3 rollers, the machined degal passes freely and hangs on the lower slave 6 and the leading 3 rollers (Fig. 2). Then sector 4 is pushed to the right and rollers 5 and 6 press the part at an angle of 120 ° to the drive roller 3, while rollers 5 and 6 self-align. The workpiece receives rotation from the drive roller 3. The tool holder 8 is brought to the workpiece by means of a cam of the camshaft 10. This moment corresponds to the position shown in fig. 3. After removing the burrs, sector 4 is retracted from the drive roller 3 so that into the resulting gap between the lower 6 and the lead 3 rollers the workpiece falls into the receiving tray 7. This moment corresponds to the position shown in FIG. 4. Next, sector 4 is brought to the drive roller 3 by such an amount that the next part, assigned for processing, can freely pass between the upper 5 and leading 3 rollers and cannot fall out of the raw 3 into the gap between the lower 6 . Then the cycle repeats.

Subject invention

A device for deburring cylindrical parts, comprising a unit for feeding parts by piece and a deburring mechanism equipped with a tool fixed in a holder, characterized in that, in order to reduce overall dimensions and increase the quality of processing, the deburring mechanism is designed as a rotary sector with support rollers for receiving parts, which is mounted for reciprocating movement relative to the drive roller and in the same plane with it,

and the tool holder is rotatable.
