Description
Technical field
The present invention relates to a kind of embroidery machine, relate in particular to embroidery machine accurate, the stabilized driving framework.
Background technology
The structure of present traditional embroidery machine framework drive system is made up of with two parallel lead rail axis 4 arc bearings, and the slide block of connecting frame is unsettled up and down, and the circular arc and the lead rail axis of arc bearing are fixed slide block at vertical direction.Will press to such an extent that very tightly could play fixation like this between bearing and the lead rail axis, also strengthen simultaneously the frictional force when mobile, it is untimely to cause driving response; Its control drive motors and driving wheel installation site are driving under the long situation at an end of guide rail on the other hand, and the deformation that belt produces also can cause driving traveled distance and required generation error, influences the embroidery quality.
The Chinese utility model patent patent No. 201120003336.5 of the applicant's application discloses a kind of embroidery machine and has used frame driving device; The slide block that comprises connecting frame, the driving wheel of connection motor, and driven pulley; Driving wheel is located on the drive track and by belt with driven pulley and is connected; Belt connects slide block simultaneously, is equipped with line slideway on the described drive track, and line slideway connects slide block.Though the structure that this kind adopts line slideway to connect slide block can realize precisely, the stabilized driving framework, technical pattern is simple relatively, performance and imperfection, the particularly loss of slide block easy abrasion.
Summary of the invention
The invention provides a kind of simple in structure, long service life, precisely, the embroidery machine of stabilized driving framework.
A kind of framework is accurate, the embroidery machine of stabilized driving; Comprise the embroidery machine frame, on the embroidery machine frame frame driving device is installed, frame driving device comprises: mounting bracket, belt, motor, guide rail, the slide block of being located at the belt wheel at mounting bracket two ends, sliding along guide rail; The slide block connecting frame; Guide rail is installed on the mounting bracket, and described guide rail is the linear pattern guide rail, and guide rail is made up of the last rail level of one, following rail level; Last rail level is provided with symmetrical two arc surfaces, and above-mentioned two arc surfaces are positioned at two arc surfaces in addition of rail level down along laterally zygomorphic being provided with of the center line of last rail level and following rail level; Described slide block comprises matrix and the end cap of being located at the matrix two ends, is provided with four engagement bands of four arc surfaces of load engagement guide rail respectively in the matrix.The engagement band of rail level and following rail level on four load engagement guide rails is set in the slide block of this kind connecting frame, makes slide block in sliding process, be in the technical purpose that absolute stable state reaches embroidery machine frame driving device stabilized driving framework.Because the slide block connecting frame is in artesian condition, four load engagement bands have improved the long-time abrasion deformation that slides and cause of the anti-limited slip block of bearing capacity of slide block, have prolonged the service life of slide block.
In four engagement bands, two engagement bands mesh two arc surfaces of rail level on the guide rail, in addition two arc surfaces of rail level under the engagement of two engagement bands; Described engagement band is gathered to arrange by a plurality of balls and constitutes.On rail level on the guide rail and following rail level, be uniformly distributed with two engagement bands respectively, increase slide block and contact stability and stressed uniformity in the sliding process with guide rail.Adopt ball to reduce frictional resistance greatly, further prolong the service life of slide block as the building block of engagement band
Described guide rail is provided with the location and installation hole of running through rail level, following rail level, is fixedly connected mounting bracket.This kind runs through the location and installation hole of rail level, following rail level, and bolt is connected and installed support, has guaranteed the perpendicularity between guide rail and the mounting bracket.Because the mounting bracket level is installed on the embroidery machine frame; Exist higher perpendicularity to guarantee that just the slide block on the guide rail is in sliding process between guide rail and the mounting bracket; With mounting bracket in other words with the absolute parallel of embroidery machine frame, the framework of certain thus connection slide block and embroidery machine frame can accomplish that relative parastate prevents that framework from tilting.The quantity in location and installation hole can be arranged along guide rail as required.
In the middle of the described mounting bracket or near the centre, be provided with the install bin of built-in driving wheel, the driving wheel periphery is connected and installed the belt wheel and the slide block at support two ends through belt.This kind is employed in the middle of the mounting bracket or near the centre driving wheel structure is set; Make driving wheel when driving belt moves, shorten the running orbit of belt; And make the stressed of belt be evenly distributed, prevent that its distortion from also having avoided framework kinematic error to occur and having improved running precision.Described driving wheel center is connected with power transmission shaft, and power transmission shaft connects motor through the governing box of built-in variable speed belt wheel group.
Described belt is an odontoid belt; The belt wheel periphery that cooperates with odontoid belt also is meshing with each other for tooth-shape structure; The driving wheel periphery that cooperates with odontoid belt also is meshing with each other for tooth-shape structure; The slide block upper surface also is a tooth-shape structure engaging tooth shape belt, realizes driving wheel through the belt drives slide block, and then drives the high accuracy that framework reaches the framework driving.
Separated in the described odontoid belt, break off two leash end that form and behind the belt wheel that passes driving wheel, mounting bracket two ends respectively, be engaged on the slide block left and right sides; The slide block left and right sides and two leash end engagement places are provided with the location and installation hole of passing slide block and two leash end, and the location and installation hole bolt that is connected is fastened on two leash end on the slide block.The odontoid belt of this kind disrupted configuration it connect compactly more when the belt wheel that connects driving wheel, mounting bracket two ends, slide block, avoids the belt distortion that the conventional belt socket join structure forms and cause influencing the accuracy that framework drives.
Described slide block side is provided with the induction projection, and the induction projection contacts the limit switch of being located at the mounting bracket two ends when slide block slides into the guide rail two ends.
The present invention makes slide block in sliding process, be in the technical purpose that absolute stable state reaches embroidery machine stabilized driving framework through rail level and following rail level on four load engagement band engagement guide rails is set in the slide block.
