Description

Изобретение относится к станкостроению, в частности к устройствам, предназначенным для сверления и нарезания резьбы. _The invention relates to machine tool industry, in particular to devices designed for drilling and threading. _

Известна многошпиндельная криво- ° шипно-шатунная головка, в корпусе которой размещены кривошипный привод и поводковая плита, кинематически связанная с последним и кривошинами шпинделей, расположенных на ^υ шпиндельной плите [1].Known multi-spindle crank ° conrod-rod head, in the housing of which there is a crank drive and a driving plate, kinematically connected with the latter and the spindle cranks located on the ^υ spindle plate [1].

Цель изобретения - расширение технологических возможностей головки.The purpose of the invention is the expansion of technological capabilities of the head.

Для этого она снабжена планшай- 15 бой, жестко связанной с поводковой плитой, причем обе плиты выполнены сменными.For this, it is equipped with a faceplate 15 that is rigidly connected to the leader plate, both plates being removable.

На фиг. 1 схематически изображена предложенная головка; на фиг.2 - 20 разрез А-А на фиг. 1.In FIG. 1 schematically shows the proposed head; in Fig.2 - 20 section aa in Fig. 1.

Многошпиндельная кривошипно-шатунная головка содержит корпус 1, внутри которого размещен кривошипный привод, выполненный в виде централь- 25 ной шестерни 2, кинематически связанной с четырьмя кривошипными водилами 3. На 'кривошипах водил 3 уста- ^хновлена планшайба 4 для крепления поводковой плиты 5. Поводковая пли- 30 та 5, кинематически связана с кривошипами рабочих шпинделей 6, размещенных на шпиндельной плите 7.Multi-spindle crank head comprises a housing 1, inside which is placed a crank drive is designed as a central pinion 25 hydrochloric 2 is kinematically coupled with the four crank planet carrier 3. 'cranks driven usta- 3 ^x Credited faceplate 4 for fixing the flanged plate 5. The driving plate 30 and 5 are kinematically connected with the cranks of the working spindles 6 located on the spindle plate 7.

Кривошипно-шатунная головка работает следующим образом.The crank head works as follows.

Крутящий момент от станка через центральную шестерню 2, кривошипные водила 3 и планшайбу 4 сообщается поводковой плите 5, которая, совершая кругообразное движение, передает его кривошипам рабочих шпинделей 6. При обработке деталей с иным расположением отверстий соответственно заменяются поводковая и шпиндельная плиты, а корпус головки с размещенным в нем кривошипным приводом остается прежним.The torque from the machine through the central gear 2, the crank carrier 3 and the faceplate 4 is communicated to the drive plate 5, which, in a circular motion, transfers it to the cranks of the working spindles 6. When machining parts with a different arrangement of holes, the drive and spindle plates are replaced accordingly, and the head housing with the crank drive located in it remains the same.

Применение изобретения позволит при минимальных затратах на изготовление путем только переналадки сменных плит значительно расширить технологическую возможность головки и повысить эффективность ее использования, например за счет переналадки.The application of the invention will allow, at the minimum cost of manufacturing, by simply changing the replacement plates to significantly expand the technological ability of the head and increase the efficiency of its use, for example due to readjustment.

Claims

The invention relates to a machine tool industry, in particular to devices for drilling and threading. Known multi-spindle crank head, in the case of which the crank drive and drive plate are located, kinematically connected with the latest and crank spindles located on the spindle plate 1. The purpose of the invention is to expand the technological capabilities of the head. For this, it is provided with a face plate rigidly connected to the support plate, and both plates are interchangeable. FIG. 1 schematically depicts the proposed head; in FIG. 2, section A-A in FIG. 1. The multi-spindle crank head includes a housing 1 inside which the cranks accommodate a drive made in the form of a central gear 2, kinematically connected with four crank waters 3. On the cranks of the carrier 3 a faceplate 4 is mounted for fastening the peeler plate 5. Pododkova Plate 5, kinematically svazana with cranks working spindles 6, placed on the spindle plate 7. Crank-rod head works as follows. The torque from the machine through the central gear 2, the crank carrier 3 and the faceplate 4 is connected to the drive plate 5, which, having made a circular motion, transfers it to the cranks of the working spindles 6. When machining parts with a different arrangement of holes, the driver and the spindle plate are replaced, and the head housing with the crank drive dispersed therein remains the same. The application of the invention will allow, at a minimum cost to manufacture, by only retooling replaceable plates, significantly expand the technological capability of the head and increase the efficiency of its use, for example, by retooling. Claim invention Multi-crank crankhead, in the body of which

a crank drive and a float plate are placed kinematically connected with the latter and the spindle cranks located on the spindle plate, characterized in that, in order to expand the technological capabilities of the head, it is equipped with a faceplate rigidly connected to the peeler plate, both plates being made replaceable .
