Description

ИзобретеЕше относитс к области сварки и может быть использовано дл подачи сварочной проволоки в зону сварки.The invention relates to the field of welding and can be used to feed welding wire to the welding zone.

Известные устройства, содержащие прижимной и ведущий рспики, жестко закрепленные на валах, не обеспечивают перемещени роликов вдоль собственных валов дл исключени искривлени подаваемой в зону сварки проволоки, что порождает нестабильность ее подачи ij.The known devices containing a clamping and driving pin, rigidly mounted on the shafts, do not move the rollers along their own shafts to eliminate the curvature of the wire fed to the welding zone, which causes instability of its supply ij.

Наиболее близким rto технической сущности и достит аемому результату к предлагаемому изобретению вл етс устройство , содержащее расположенные в корпусе па параллельных валах подающие ролики и механизм регулировки положени подающих роликов 2.The closest rto of the technical essence and the available result of the invention is a device comprising feed rollers located in a housing parallel to the shafts parallel to the shaft and a mechanism for adjusting the position of the feed rollers 2.

Однако такое устройство обладает низкой маневренностью, так как сместить ролики на валах возможно на небольшое рассто ние из-за ограниченного диапазона перемещени относительно свариваемого стыкаHowever, such a device has low maneuverability, since it is possible to displace the rollers on the shafts by a small distance due to the limited range of movement relative to the welded joint

Целью изобретени вл етс повышение маневренности устройства путем увеличени диапазона регулировани положени подающих роликов.The aim of the invention is to increase the maneuverability of the device by increasing the range of adjustment of the position of the feed rollers.

Это дост.таетс за счет того, что в предлагаемом устройстве механизм регулировки положени роликов выполнен в виде винтовых пар, винты которых размещены внутри валов, а гайки жестко св заны с подающими роликами.This is due to the fact that, in the proposed device, the mechanism for adjusting the position of the rollers is made in the form of screw pairs, the screws of which are placed inside the shafts, and the nuts are rigidly connected to the feed rollers.

Кроме того, с целью исключени проскальзывани проволоки, одна из винтовых пар подпружинена.In addition, in order to avoid wire slippage, one of the screw pairs is spring-loaded.

На . 1 показано предлагаемое устройство , общий вид; на фиг. 2 - разрез по А-А на фиг. 1.On . 1 shows the proposed device, a general view; in fig. 2 is a section along A-A in FIG. one.

Claims

The welding wire feeder consists of body 1, in which two direct current electric motors 2 are rotated, rotating with bevel gear 3 and 4 by bevel gears 5 and 6 of the differential mechanism. Gears 5 and 6 are rigidly connected with gears 7 and 8, knitted with gear 9, drove 10, transmitting rotation through gears 11, 12, 13 onto shaft 14, on which gear 15 is mounted, coupled with gear 16 coupled to shaft 17 Feed rollers 18 and 19 are attached to the end of gear 15 and 16, which feed the welding wire 20 into the welding zone. Inside the shafts 14 and 17, an eolique position adjustment mechanism, made in the form of screws 21 and 22, is rigidly connected to gears 15 and 16 by pins 23. One of screws 21 is screwed with sleeve 24 acting on the spring 25. The device starts with installation rollers 18 and 19 to the desired position with the help of viits 21. Then, Sh1zhima on the sleeve 24, the working surface of roller 19 is retracted from the working surface of roller 18, between and which and the welding wire 20. Then the electric motors 2 are started, and change the speed of one of the engines lei, shot |) ayut the desired wire feed speed. Roller 19 at the expense of spring 25 I will do a wire 2O to track 18, excluding its slippage. Such a constructive solution allows the rollers 18 and 19 to be smoothly moved along the shafts 14 and 17, which increases the maneuverability of the device by two times, since the rollers can be positioned as asymmetrically, and in different directions (shifted to the left or right), and symmetrically relative to the body device, allowing assembly to take place near the walls (with an asymmetrical arrangement of the rollers) and in a narrow well symmetrical with respect to the welded joint (with symmetric arrangement of the rollers). Claim 1. Device for supplying welding wire containing feed rollers and feed roll adjustment mechanism located in a housing on parallel shafts, characterized in that in order to increase maneuverability by increasing the adjustment range of the feed roll rollers, screw pairs, the screws of which are placed inside the shafts, and the nuts are rigidly connected to the feed rollers. 2. The device according to claim 1, in connection with the fact that, in order to prevent spraying of the wire, one of the screw pairs is spring-loaded.
