(5t) ЗАЧИСТНАЯ ГОЛОВКА(5t) WIPER HEAD

t . :. t. :.

Изобретение относитс к станкостроению и может найти применение в металлургической промышленности в частности, при сплошной зачистке заготовок инструментом, предназначенным дл обеспечени высокопроизво дителъного шлифовани .The invention relates to a machine tool industry and may find application in the metallurgical industry, in particular, in the continuous cleaning of workpieces with a tool designed to provide high efficiency grinding.

Известна зачистна головка, включающа планшайбу с инструментом, смонтированную на шпинДеле посредством зажимного болта и опорной шайбы СП.A known scraper head incorporates a faceplate with a tool mounted on a spinner by means of a clamping bolt and an SP washer.

Однако известна конструкци креплени планшайбы недостаточно надежна дл креплени т желонагружен- . ных планшайб при силовом обдирочном шлифовании. Кроме того, не предусмотрен механизм дл сн ти планшайбы со шпиндел , что снижает его производительность .However, the known design of the faceplate attachment is not reliable enough to attach the yellowing-mount. faceplate when force grinding. In addition, there is no mechanism for removing the chuck from the spindle, which reduces its performance.

Цель изобретени - увеличение производительности путем сокращени вспомогательного времени на заменуThe purpose of the invention is to increase productivity by reducing the auxiliary time for replacement

планшайбы и овышение надежности ее креплени .faceplates and increased reliability of its attachment.

Дл достижени поставленной цели зачистна головка снабжена размещенным на зажимном болте, оснащенном поршнем, плунжером с пазом, при этом в плунжере и зажимном болте выполнены соойцающиес полости, заполненные гидропластом, а в пазу плунжера установлена опорна шайба с возto можностью взаимодействи с планшайбой , снабженнойнесколькими отжимными элементами, размещенными в выпол ненных в планшайбе полост х, сообщаю 1цихс между собой и заполненных гидfS ропластом с возможностью взаимодействи со шпинделем.To achieve this goal, the scraper head is equipped with a piston, a plunger with a groove placed on the clamping bolt. placed in the cavities made in the faceplate, I communicate 1xx between each other and roplast filled with hydraulic sps that can interact with the spindle.

На чертеже изображена зачистна головка, общий вид.The drawing shows a stripping head, a general view.

Claims

The cleaning head includes a spindle del 1, a chuck 2 that is mounted on a conical surface 3 of spindle 1. A clamping bolt k is mounted on the spindle face, and is placed in the plunger 5. The clamping bolt has a cavity 6, which is connected to the cavity 7 of the plunger 5.a also a nut 8, the pressure screw 9 and the piston 10. Cavities 6 and 7 are filled with hydroplast. The plunger 5 is made with grooves 11 in which the supporting washer 12 is mounted. The washer 2 has interconnected cavities 13. in which a squeezing device is mounted, for example, made in the form of a power element 15, plungers 16 in contact with the spindle 1, and a hydraulic layer filled 13. When the stripping head is in operation, the faceplate needs to be replaced due to wear of the cutting tool. For fastening the faceplate 2 is hung on the conical surface 3 of the spindle 1. At the end of the spindle there is a clamping bolt C placed in the plunger 5. In the groove; 11 of the plunger 5 install the support washer 12. Rotate the pressure screw 9 which moves the piston 10 in the cavity 6. in the cavities 6 and 7 filled with hydroplastic material, a hydrostatic pressure is created, under the action of which the plunger 5 moves and, acting through the support washer 12 on the faceplate 2, puts the faceplate 2 on the conical surface 3 of the spindle 1. After pressure screw E 5 plunger stopper t nut 8. Deburring head is ready for operation. To remove the faceplate 2, turn the pressure screw 9 i. E. relieve pressure in the cavity 6 and -7, unscrew the nut 8, relieve the washer 12. Now, moving the force element 15 create a hydrostatic pressure in the cavity 13, which acts gs through the plungers 16 on the spindle 1 and creates a force sufficient to move the faceplate from the cone. Thus, the proposed design of the wiper head allows reducing the time for tool replacement, i.e. increase productivity and ensure reliable fastening of the faceplate with minimal energy consumption. The invention of the Cleaning Head, including a faceplate with a tool, mounted on a spindle by means of a clamping bolt and a support washer, so that, in order to increase productivity by reducing the auxiliary time for replacing the faceplate and improving the reliability of its mounting, the cleaning head is equipped placed on a clamping bolt equipped with a mouthpiece, a plunger with a groove, while in the plunger and the clamping bolt there are made communicating cavities filled with a hydraulic layer, and in the groove of the plunger is installed Molecular washer to cooperate with a face plate provided with several squeezing elements arranged in a faceplate formed cavities communicating with each other and filled GIDROPLAST to cooperate with the spindle.
