Изобретение относитс к механической обработке прецизионных отверстий. .The invention relates to the machining of precision holes. .

Известны устройства дл хонннговани отверстий с компенсацией износа брусков и контролем размера обрабатываемого отверсти , содержашеее механизм разжима хона с иглой разжима и калибр-ограничитель перемещени брусков 11 Known devices for honing holes with wear compensation for bars and controlling the size of the hole being machined, containing a hinging mechanism with a unclamping needle and a gauge-limiter for moving bars 11

Цель изобретени - упростить конструкцию устройства..The purpose of the invention is to simplify the design of the device ..

Дл этого механизм раз жима снабжен неподвижно закрепле1шыми кЬнечными выключател ми и регулируемым ограничителем, а игла разжима - командным флажком, кроме того, устройство снабжено фрикдионом. For this, the expansion mechanism is provided with fixedly fixed knit switches and an adjustable stopper, and the unlocking needle with a command flag, in addition, the device is equipped with a frictional one.

Така конструкци устройства позвол ет перед обработкой очередной детали произвести точную компенсацию износа брусков, вызванного обработкой предьщушэй детали .Such a design of the device allows, before processing the next part, to make an exact compensation for the wear of the bars caused by the processing of the front part.

На фиг, 1 показано предложенное устройство , разрез; на фиг. 2 - то же, в плане.Fig, 1 shows the proposed device, the section; in fig. 2 - the same in terms of.

Claims

The unclamping needle 1, which mixes the hone bars 2 in the radial direction, is connected to the drive through a screw drive gear. The command flag 3 is associated with one of the needle drive elements of unclamping 1 by the frictional forces created by the spring 4, and interacts during operation with the limit switches 5 n in, respectively. The bars are compressed to the size reached. The device is equipped with an adjustable stopper 7 for moving the command flag 3 and a gauge-limiter 8 for moving the hone bars 2, which is set coaxially with the hones 2 outside the treatment area. Before processing the first part of the batch, an adjusting test unclamp is made, at which the command flag 3, passes by the end switch b, stops with the adjustable stop 7, and the unclamping needle 1 continues to mix the previously fully compressed bars 2 up to the stop with a certain force in the caliber limiter 8. The adjustable limiter 7 is set so that the path length of the command flag 3 from the point of influence on the limit switch 6 to the limiter 7 corresponds to the difference in the size of the gauge - limited Ithel parts 8 and predetermined size. After adjusting the test release, the bars are compressed, which continues until the command fly. Button 3, moving together with the unclamping needle 1, acting on the limit switch 5, will not give the command to Bar compressed. Compression termination allows the machining cycle to be started, during which caliber limiter 8 is located in a non-machining zone above the part. The cycle of the sonic vani continues until the command flag 3 is mounted on the end & 6 switch. The size of the processed part will be smaller than the size of the gauge - limit the value corresponding to the distance of the impact of the 3 flag on the end switch 6 and the stop point of the command flag adjustable limiter 7. At the same time, it is possible to adjust the device more accurately to obtain the specified size of the machined part. At the end of the hingo & any cycle, the bars are compressed before the company is formed. The bars are squeezed. The device is prepared for a test release, during which the Hohn 2 bar is inside the gauge limiter 8. With the test release in the absence of wear of the Hoh bars 2, the command flag 3 will not be displaced relative to the unclamp needle 1 and the size of the machined parts will not change. If the bars wear out, then with control release, command flag 3, until reaching limiter 7, will stop, and unclamping needle 1 will continue moving until the hone 2 bars are pressed to caliber-limiter 8. This will result in mixing command flag 3 relative to unclamping needle 1 by an amount corresponding to the wear of the bars, and, consequently, to accurate compensation of wear. Formula from a re 1 and 1. A device for honing holes with wear compensation for bars and control of the size of the hole being machined, contains a hing mechanism with a needle for opening and a gauge-limiter for mixing bars set coaxially with hones outside the zone. Work, about tl and h s yushch S in there, “the fir-tree of begging for the kokrustashi; (1I b | 1 | zzhima is provided with irresistively fixed end switches of the no. With an adjustable limiter, and the yoke is unclamped with a command flag.,, ...,.

2. The device according to claim 1, which is different from the fact that, in order to mix the command flag with respect to the unclamping needle during control, it is equipped with a friction clutch.
