Abstract
The invention relates to a circular knife cutting machine with a quick detachable worm wheel, comprising an electric motor (1), an electric motor end cover (5), a worm wheel and worm reducer and a blade (8). The worm gear reducer is arranged in the electric motor end cover (5); the electric motor end cover (5) is internally provided with the cavity of the worm wheel, which is called as a worm wheel chamber; a worm (7) is connected with the output end of the electric motor (1); a worm wheel shaft (10) of a worm wheel (4) is fixed on the electric motor end cover (5) by a screw cap (6); and the blade (8) is directly and fixedly installed on the worm wheel (4). The circular knife cutting machine is characterized in that the worm wheel chamber extends for a certain width towards the non-meshing surface to form a long circle; the extended width ensures that the crest of the worm wheel (4) can disengage the meshing with the worm (7) when the crest runs into a wall; the hole for fixing the worm wheel shaft on the electric motor end cover (5) is amplified until the worm wheel (4) can disengage the meshing state when the screw cap (6) of the fixed worm wheel shaft is dismounted; a locating ring (12) is added into the amplified hole, and the worm wheel can disengage the meshing position when the locating ring (12) is dismounted. In the invention, the worm wheel is very easy to dismount and exchange.
Description
(1) technical field
The present invention relates to a kind of electric tool of cutting cloth, especially relate to a kind of circular knife cutting machine of quick detachable worm wheel.Belong to the stitch machine technical field.
(2) background technology
Existing circular knife cutting machine is made up of motor, worm reducer, blade, support, base plate etc. shown in Fig. 1～2.The rotating speed of motor drives the purpose that the blade rotation reaches the cutting cloth after slowing down through worm reducer.Blade directly is fixed on the worm gear, and the center of worm gear is by the worm shaft location, and worm shaft covers in motor terminal with fixed by nut, and worm screw is installed on the axle of motor.Worm shaft promotion worm gear and blade are around the worm-wheel shaft rotation during motor operation.This circular knife cutting machine compact conformation, volume is little in light weight, uses lightly flexibly, and cutting efficient is high.In order to reduce noise, worm gear is generally made with nonmetallic materials, and worm gear compares easy abrasion like this, and in the length of life of circular knife cutting machine, changing worm gear is common occurrence.The dismounting worm gear is the thing of a trouble on existing circular knife cutting machine, because the tooth of worm gear is a circular arc, diameter was little in the middle of the both sides diameter was big, can not directly unload down along the axis of worm gear.Unload worm gear and will extract worm screw earlier, and worm reducer and motor are one, just can extract worm screw so will break motor that this will very professional maintenance personal just can carry out.Often dismantle the motor component of the fragile precision of motor in addition, the assembly precision of circular knife cutting machine is descended, big, shortening in service life that running noise becomes.
(3) summary of the invention
The objective of the invention is to overcome the shortcoming of existing circular knife cutting machine, design a kind of worm gear and dismantle and change all the circular knife cutting machine of quick detachable worm wheel easily.
The objective of the invention is to realize like this: a kind of circular knife cutting machine of quick detachable worm wheel; Comprise motor, End cover for motor, worm type of reduction gearing and blade; Worm type of reduction gearing is arranged in the End cover for motor, and the cavity that worm gear is set in the said End cover for motor is referred to as the worm gear chamber, and the worm screw of worm type of reduction gearing links to each other with motor output end; The worm-wheel shaft of worm gear covers in motor terminal with fixed by nut; The center of worm gear is by the worm-wheel shaft location, and blade directly is fixedly mounted on the worm gear, is characterized in: said worm gear chamber is relaxed a bit to the one side of non-engagement; Form Long Circle, the width of emitting can break away from the engagement with worm screw when the worm gear tooth top is rebuffed; Cover the hole that is used for fixing worm-wheel shaft to motor terminal and amplify, when being amplified to the nut that unloads fixing worm-wheel shaft, worm gear can break away from engagement; In the hole of amplifying, add centring ring, guarantee the positional precision of worm-wheel shaft when centring ring is on the throne, can let the worm gear disengaged position when unloading.
The rotating speed of motor slows down back drive blade around the worm-wheel shaft rotation through worm and gear, reaches the purpose of cutting cloth.
The invention has the beneficial effects as follows:
The present invention has done very little change to the design of existing circular knife cutting machine, and the cost of input effect very little, that produce is a lot.Circular knife cutting machine dismounting and replacing worm gear after the improvement are very easy; Just can pull down worm gear as long as unload nut and centring ring; Installation needs only worm gear set on worm-wheel shaft, passes the fixing hole that motor terminal covers to the screw on the worm-wheel shaft again, and it is just passable to load onto centring ring and nut.Do not need service technique also without the professional, common people's multipotency is done.Can not damage motor can not influence service life yet, greatly reduces user's maintenance cost.

(5) specific embodiment
Referring to Fig. 3～4, Fig. 3 is the Facad structure sketch map of the circular knife cutting machine of quick detachable worm wheel of the present invention.Fig. 4 is the left side view of Fig. 3.Can find out that by Fig. 3 and Fig. 4 the circular knife cutting machine of quick detachable worm wheel of the present invention is made up of motor 1, End cover for motor 5, worm type of reduction gearing, blade 8, support 3 and base plate 2.Support 3 is installed on the base plate 2; Motor 1 is installed on the support 3, and worm type of reduction gearing is arranged in the End cover for motor 5, and the cavity that worm gear is set in the said End cover for motor 5 is referred to as the worm gear chamber; The worm screw 7 of worm type of reduction gearing links to each other with motor 1 output; The worm-wheel shaft 10 usefulness nuts 6 of worm gear 4 are fixed on the End cover for motor 5, and the center of worm gear 4 is by worm-wheel shaft 10 location, and blade 8 directly is fixedly mounted on the worm gear 4.
The present invention relaxes the circular worm gear chamber of existing circular knife cutting machine a bit to the one side of non-engagement, forms Long Circle, and the width of emitting can break away from the engagement with worm screw 7 when worm gear 4 tooth tops are rebuffed; Amplify the hole that is used for fixing worm-wheel shaft on the End cover for motor 5, when being amplified to the nut 6 that unloads fixing worm-wheel shaft, worm gear 4 can break away from engagement.In the hole of amplifying, add centring ring 12, centring ring 12 guarantees the positional precision of worm-wheel shaft when on the throne, can let the worm gear disengaged position when unloading, and dismantles more convenient.
