(54) ЗАГРУЗОЧНО-РАЗГРУЗОЧНОЕ УСТРОЙСТВО(54) LOADING AND UNLOADING DEVICE

1one

Изобретение относитс к станкостроению и может быть использовано в токарных стеках дл обработки сплошных дисков по наружному диаметру.The invention relates to a machine tool industry and can be used in lathe stacks for machining solid discs in outer diameter.

Известны загрузочно-разгрузочные устройства , содержащие лотки загрузки и выгрузки , соосный шпинделю подпружиненный ловитель дл предварительного базировани детали, механизм поштучной выдачи и механизм , удерживающий обрабатьшаемую деталь в зафиксированном положении за счет сил трени .Loading and unloading devices are known, comprising loading and unloading chutes, a spring-loaded safety device coaxially with the spindle for pre-basing the part, a piecewise dispensing mechanism and a mechanism that holds the workpiece in a fixed position due to friction forces.

Такое устройство не обеспечивает возможности обработки сплошных дисков по наружному диаметру.Such a device does not provide the possibility of processing solid discs on the outer diameter.

Цель изобретени - устранение указанного недостатка.The purpose of the invention is to eliminate this drawback.

Это достигаетс тем, что в предлагаемом устройстве подпружиненный ловитель установлен на передней бабке станка, отводатс из зоны резани до начала обработки упором и удерживаетс в отведенном положении до оконч ани обработки фиксатором.This is achieved by the fact that in the proposed device a spring-loaded safety device is installed on the fore headstock of the machine, is retracted from the cutting zone before the treatment begins with the anvil and held in the retracted position until the end of the treatment with the lock.

На фиг. 1 показано предлагаемое устройство , вид сверху; на фиг, 2 - разрез по FIG. 1 shows the proposed device, top view; fig 2 - section along

А-А на фиг, 1; на фиг. 3 - разрез по ББ на фиг, 1.A-A in FIG. 1; in fig. 3 is a section through BB in FIG. 1.

Загруаочно-разгрузочное устройство состоит из корпуса 1, закрепленного на фланце передней бабки токарного станка, ловител 2, упорной втулки 3, пружины 4, втулки 5, ведущей опоры 6, жестко св занной со шпинделем 7 передней бабки 8, плунжера 9, штока зажима 10 со сферической опорой 11, упора 12, жестко св занного с пинолью 13 задней бабки 14, копирной линейки 15, фиксатора 16, лотка загрузки 17, штифта 18 и конечных выключателей 1922 , пружин 23 и 24, пневмоцилиндра 25 и бункера 26,The load unloading device consists of a body 1 fixed to the flange of the front head of the lathe, catcher 2, thrust bushing 3, spring 4, bushing 5, drive bearing 6 rigidly connected with spindle 7 of the front headstock 8, plunger 9, clamp stem 10 with a spherical support 11, an emphasis 12, rigidly connected with a quill 13 of the tailstock 14, a ruler 15, a clamp 16, a loading tray 17, a pin 18 and limit switches 1922, springs 23 and 24, a pneumatic cylinder 25 and a hopper 26,

Устройство работает следующим образом.The device works as follows.

Claims

After the machining process is completed, the machine caliper returns rapidly to its original position, the stop 12 mounted on it prepares the stop sleeve 3, which is rigidly connected to the safety gear 2, and presses the limit switch 19, which gives the command to unclamp the machined part. The quill 13 is moved to the right. At the beginning of the course of the quill 3 part 27, unclamp; - hardware, but to the beginning {th Nfo element (under the action of the spring 24 and the plunger 9) the part is pressed against the support 11; upon further movement of the support 11, the part falls under the force of gravity into the unloading tray. In the course of the quill stroke 13 of the copier ruler 15, is rigidly connected with the quill, it acts on the clamp 16 and compresses the spring 23, Clamp 16 releases the stop sleeve 3 associated with the safety gear 2, and under the action of the spring 4 the safety device 2 is primed to the right up to the stop pins 18. In this position, a gap of 1 mm remains between the safety gear 2 and the load compartment 17. Pi zero 13 in its extreme right position (presses the limit switch 2O, which commands the piece pneumatic cylinder; issuing 25 to feed one deGali into the loading tray 17 from the hopper 26. The pneumatic cylinder 25 returns to its original position, presses the limit switch 21 which gives the command to clamp the part. I Pinol 13, moving to the left, pushes the part with clamp rod U and support 11: from tray 17 to safety device 2, which centers part 27 relative to the spindle axis of the machine and, overcoming the force of the spring 4, presses the part to the leading support 6. At the end of the stroke of the quill 13 to the left, the coprnar ruler 15 releases the clamp 16, preparing it for fixing the thrust hub 3. At the end of the stroke the quill 13 presses the limit switch 22, which gives the command to enable the caliper supply, and the processing details 27. Moving to the left, the machine support, pressing spring 4 by the stop 12, withdraws the safety device 2 335 to the left through the stop sleeve 3. At the same time, the stop sleeve 3 of the shoulder bends latch 16, but after passing over it, it releases it. Under the action of the spring 23, the latch 16 returns to its original position and locks the safety device 2 in the leftmost position. After an eye of the machining part, the caliper returns to its original position, and the cycle repeats. The proposed loading and unloading device allows you to automate the processing of flattened discs on the outer diameter, reduce the time for loading and unloading parts, accurately center the part relative to the spindle axis, which leads to an even positioning of the processing allowance and increase accuracy and quality of machined parts. Claims Loading and unloading device containing loading and unloading trays, cooc-t spindle spring-loaded safety device for 1 pre-base part, the mechanism of the piece and the mechanism holding the workpiece in a fixed position due to the forces of friction, iv is the fact that , for the purpose of machining solid discs on the outer diameter, it is equipped with a stop and a lock and the spring loaded safety device is set to. the head of the machine with the possibility of cutting from the cutting zone and fixing in the retracted position when interacting with the stop.
