Description

Изобретение относится к машиностроению и строительству и может.найти применение в случаях, когда в глухом гнезде корпусной детали или стенки, изготовленных из мягкого материала, необходимо точно установить резьбовую втулку без повреждения·, корпусной детали.The invention relates to mechanical engineering and construction and can be used in cases where in a blind socket of a body part or wall made of soft material, it is necessary to precisely install a threaded sleeve without damage to the body part.

Известен способ монтажа резьбовой втулки в глухое гнездо корпусной детали, изготовленной из мягкого ’металла, путем сверления центрального резьбового глухого отверстия во втулке и последующего ввинчивания втулки в глухое гнездо корпусной детали fl].There is a method of mounting a threaded sleeve in a blind socket of a case made of soft metal by drilling a central threaded blind hole in the sleeve and then screwing the sleeve into the blind socket of the housing part fl].

Однако данный способ непригоден в случаях, когда требуется очень точно располагать втулку относительно корпусной детали.However, this method is unsuitable in cases where you need to very accurately position the sleeve relative to the body part.

Известен также способ монтажа резьбовой втулки в глухое гнездо корпусной детали, изготовленной из. мягкого материала, путем ввинчивания в упомянутое гнездо заготовки втулки, имеющей форму сплошной цилиндрической детали с наружной резьбой и последующего сверления в ней.глухого отверстия с применением съемного приспособления, например, ⁵ кондуктора, ограничивающего ход режущего инструмента на заданную величину, причем приспособление монтируют на наружной поверхности корпусной детали или на станке L2J. Однако такой способ монтажа значительно усложнен и не исключает возможности повреждения корпусной детали сверлом.There is also known a method of mounting a threaded sleeve in a blind socket of a body part made of. soft material, by screwing into the aforementioned socket a billet of a sleeve having the form of a continuous cylindrical part with an external thread and then drilling a blind hole using a removable device, for example, ⁵ conductors restricting the cutting tool to a predetermined amount, and the device is mounted on the external the surface of the body part or on the L2J. However, this installation method is significantly complicated and does not exclude the possibility of damage to the body part with a drill.

Цель изобретения - упрощение мон¹⁵ тажа втулки и надежное предупреждение повреждения корпусной детали сверлом.The purpose of the invention is the simplification of mon ^{15 of the} sleeve and the reliable prevention of damage to the body part with a drill.

Указанная цель достигается тем_г2Q что перед ввинчиванием заготовки втулки в глухое гнездо корпусной детали, на дно этого гнезда устанавливают пластину, изготовления» из материала, твердость которого превышает твердость материалаThis object is achieved by the fact that before 2Q _g screwing the sleeve blank into the blind slot of the base member, the bottom plate of the socket set, producing "of a material whose hardness exceeds the hardness of the material

Claims

The claims of the sleeve.

The drawing shows a threaded sleeve mounted in the socket of the body part, section.

In the body part 1 made of soft material, a socket 2 is made, on the bottom 3 of which a plate 4 made of hard material is installed, then a workpiece is screwed into the socket 2, sleeves 5 having the form of a continuous cylindrical part with an external thread 6 are then drilled in the blank of sleeve 5 is blind axial, hole 6 with thread 7.

Drilling holes 6 for the fastener is carried out with a conventional drill with a sharpening angle for the material of the sleeve, the drilling depth is controlled on a machine scale. If for some reason the drill penetrates into the sleeve to a depth more calculated, then on its way it meets a plate 4 of a material with a higher hardness for which the sharpening angle jj of the drill is not designed. There is a blunting of the drill and its further introduction into the plate 4 is stopped.

A method of mounting a threaded sleeve in a blind socket of a body part made of soft material by screwing into the said socket a blank of a sleeve having the form of a continuous cylindrical part and then drilling a blind axial hole with thread on the side surface in this blank 10 with the fact that, in order to simplify installation and prevent damage to the housing part by a drill, before screwing the billet blank into a blind socket, a plate made of material is installed on the bottom of the latter, whose spine exceeds the hardness of the material of the sleeve.
