Description

Известны способы измерени  температуры резани  металлов путем создани  естественной термопары между сверлом и изделием. Однако они не обеспечивают достаточной точности измерени .Methods are known for measuring the cutting temperature of metals by creating a natural thermocouple between the drill and the product. However, they do not provide sufficient measurement accuracy.

Предлагаемый способ отличаетс  от известных тем, что пластинку из твердого сплава изолируют от корпуса сверла прокладками , поверхность корпуса сверла покрывают изолирующим составом, а место холодного спа  вынос т из зоны нагрева и изолируют обрабатываемую деталь от станка. Это позвол ет повысить точность измерени  температуры резани  путем устранени  вли ни  паразитных термоэл ектродвижущих сил.The proposed method differs from the known ones in that the carbide plate is insulated from the drill body with gaskets, the surface of the drill body is covered with an insulating compound, and the place of the cold spa is removed from the heating zone and the workpiece is isolated from the machine. This makes it possible to increase the accuracy of cutting temperature measurement by eliminating the influence of parasitic thermoelectromotive forces.

На чертеже изображена конструкци  сверла, по сн юща  предлагаемый способ измерени  температуры резани  металлов.The drawing shows a drill structure illustrating the proposed method for measuring the temperature of cutting metals.

Элементами естественной термопары в конструкции сверла  вл ютс  пластинка 1 твердого сплава и обрабатываема  деталь 2. Дл  этого в стандартный корпус сверла 5 стандартна  пластинка / твердого сплава не впаиваетс , а плотно вставл етс  и изолируетс  от корпуса слюд ными прокладками 4 и 5. При сверлении пластинка твердого сплава удерживаетс  в корпусе силами резани . Дл  центрировани  пластинки / в корпусе сверление производитс  либо с помощью текстолитовой кондукторной втулки 6, либо по предварительно просверленному отверстию в обрабатываемой детали с диаметром, равным диаметру пластинки 1.The elements of a natural thermocouple in the construction of the drill are plate 1 of hard alloy and workpiece 2. For this, the standard plate of the standard plate / hard alloy is not soldered in, but firmly inserted and insulated from the case with mica pads 4 and 5. When drilling the plate hard metal is held in the housing by cutting forces. To center the lamina / in the housing, the drilling is carried out either with a textolite conductor sleeve 6 or through a pre-drilled hole in the workpiece with a diameter equal to the diameter of the lamina 1.

Дл  устранени  паразитных термопар между твердосплавной пластинкой 1 и корпусом сверла 3 при замыкании их между собой отработанной стружкой корпус сверла 3 покрываетс  изолирующим составом (например, бакелитом). Обрабатываема  деталь 2 изолируетс  от стан№ 152327- 2 -In order to eliminate parasitic thermocouples between the carbide plate 1 and the body of the drill 3 when they are closed with each other, the body of the drill 3 is covered with an insulating composition (for example, bakelite). Work piece 2 is isolated from st. No. 152327-2 -

ка прокладкой 7 дл  устранени  вли ни  паразитных термопар, возникающих между отдельными детал ми станка.as a gasket 7 to eliminate the influence of parasitic thermocouples arising between the individual parts of the machine.

Дл  исключени  вли ни  паразитной термоэлектродвижущей силы, могущей возникнуть при нагреве пластинки / в месте спа  к ней проводника 8, место спа  отводитс  от зоны нагрева посредством твердосплавного контактного столбика 5. Контактный столбик располагаетс  в отверстии, просверленном в теле корпуса сверла 3 и изолируетс  от корпуса слюд ной прокладкой 10. Столбик прижимаетс  к торцу рабочей твердосплавной пластинки / с помощью пружины //. Дл  сн ти  электродвижущей силы с вращающейс  твердосплавной пластинки на корпус сверла насаживают медное, токосъемное кольцо 12, изолированное от корпуса текстолитовыми дисками 13 и 14. Кольцо скрепл ют с дисками винтами 15. Съем электродвижущей силы с кольца производ т с помощью щеток 16. Концы проводов от щеток и обрабатываемой детали присоедин ют к клеммам регистрирующего прибора 17.To eliminate the influence of parasitic thermoelectromotive force, which can occur when the plate is heated / in the spa place of the conductor 8 to it, the spa is removed from the heating zone by means of a carbide contact bar 5. The contact bar is located in the hole drilled in the body of the drill bit 3 and is insulated mica gasket 10. The pole is pressed against the end of the working carbide plate / by means of a spring //. To remove the electromotive force from the rotating carbide plate, a copper, current collector ring 12 insulated from the body with textolite discs 13 and 14 is pushed onto the drill body. The ring is fastened to the discs with screws 15. The electromotive force is removed from the ring using brushes 16. Wire ends from the brushes and the workpiece is connected to the terminals of the recording device 17.
