According to the sewing machine part driving device, the overall mechanical control structure is simplified, and independence of a trimming and presser bar lifting assembly and a main driving system is achieved; trimming efficiency can be improved, vibration and noise can be reduced, and meanwhile, by means of a transmission mechanism and mechanism coherence, cost and technological difficulty are reduced, production efficiency is improved, and later-stage maintenance is facilitated.
Description
Technical field
The utility model relates to a kind of accessaries of sewing machine drive unit.
Background technology
Original sewing device transmission system mainly adopts upper and lower main shaft Bevel Gear Transmission and two kinds of modes of belt transmission gear-box speed change commutation.The ordinary straight of its total upper and lower main shaft Bevel Gear Transmission is driven computer flat sewing machine and is mainly comprised: frame, upper main shaft, epicone teeth drive pair, perpendicular power transmission shaft, lower cone teeth drive pair, lower main axis.Wherein, upper main shaft, lower main axis, perpendicular power transmission shaft, be installed in frame, in driven by motor, main shaft rotates by epicone teeth drive pair and drives perpendicular power transmission shaft to rotate, and perpendicular power transmission shaft is again by the transmission of lower cone teeth drive pair driving lower main axis.This transmission mechanism is simpler, but upper and lower cone teeth drive pair is high to installation, processing request, and noise is large and noise is difficult controls, and gives oil mass large, increases the fuel-displaced probability of Sewing machines; Directly the driving computer flat sewing machine without oil and mainly comprise of another kind of belt transmission gear-box speed change exchange system: frame, upper main shaft, belt transmission pair, lower main axis, deceleration reverse box.Wherein going up main shaft, lower main axis, deceleration reverse box is installed in frame, in driven by motor, main shaft rotates, rotate by the moving lower main axis of belt transmission subband, drive lower main axis turn to rotary speed movement and drive cloth feeding mechanism motion to set by gear-box speed change exchange system.This transmission mechanism is by using belt transmission to reduce noise and lubricating oil use, but integrated model design is complicated, cost is high, and mounting process is not good, and belt rotation system inconvenient maintenance.
Utility model content
The purpose of this utility model is to provide a kind of Novel tailoring equipment transmission system, avoids that the machining accuracy that runs in common computer flat seam machine Bevel Gear Transmission is not high, stability is low, noise vibration is large, needs the problem of oil supply.
The utility model provides a kind of accessaries of sewing machine drive unit, and described device comprises that motor (4), frame (7), trimming assembly (1), trimming drive seat (2), trimming crank (3), presser foot lifter cam (5), presser foot lifter depression bar (8), presser foot lifter push rod component (6); Wherein motor (4) is installed on frame (7) bottom by motor shaft (9) two ends fixture axle beds (10), motor fixing seat (11).Stretch out at motor shaft (9) two ends of motor (4), and trimming crank (3) and presser foot lifter cam (5) are installed on respectively in motor (4) two end axles.Motor (4) drives trimming crank (3) to be rotated counterclockwise (facing from motor afterbody), drives seat (2) to drive trimming assembly (1) to carry out trimming action by trimming.Motor (4) drives presser foot lifter cam (5) turn clockwise (facing from motor afterbody), to pressing down presser foot lifter depression bar (8), then by driving foot lifting mechanism to perform an action to pressing down presser foot lifter push rod component (6).The beneficial effects of the utility model are: a kind of accessaries of sewing machine drive unit that the utility model provides, drive source by individual motor as presser foot lifter push rod component and trimming assembly, replaced existing Sewing machines main drive motor to drive by cam mechanism, electromagnet is as the trimming assembly drive pattern of driving switch; Use independent driving motor to replace original presser foot lifter push rod component drive pattern simultaneously.Greatly simplify overall mechanical control structure, realized the independence of trimming, presser foot lifter assembly and main drive system.By accessaries of sewing machine drive unit described in the utility model, can improve trimming efficiency, reduce vibration, noise, by transmission mechanism and the coherence of mechanism, reduce costs and technology difficulty simultaneously, enhance productivity, and be beneficial to later maintenance.
