Abstract
The utility model relates to a high-speed linear guide rail pair which comprises a guide rail, a sliding block, a turning device, a rubber dustproof plate and a steel ball, wherein the inner side of the sliding block is provided with a Gothic double-arc roller path adaptive to the shape of the section of the outer side of the guide rail; the steel ball for bearing load is arranged in the roller path; a positioning boss is arranged on the back of the sliding block; the sliding block is arranged on the guide rail by the steel ball and can move axially along the guide rail; and the turning device for leading the steel ball to turn around is fixed at two ends of the sliding block so that the steel ball can do endless circulating movement on the guide rail along with the sliding block. In the utility model, as the positioning boss is designed on the back of the sliding block, installing and centering standard is provided for the assembly of a whole machine, so that the assembly precision is improved, a color changing device can run stably at high speed, thermal deformation resistant capability is improved after the long-time use of the machine, shock resistant and vibration resistant capabilities of a device during starting and stopping are enhanced, and the whole machine is stable and reliable in high-speed operation.
Description
Technical field
The utility model relates to a kind of high-speed straight-line guiding pairs, and it is mainly used in the automatic colour changing device of high-speed electronic calculator embroidery machine, also has to be used for instrument and apparatus on a small quantity, belongs to electric mechanical, underloading machinery, precision instrumentation field.
Background technique
Employed linear guide pairs in the automatic colour changing device of domestic computerized emboridering machine, constitute by guide rail, slide block, back device, rubber dust guard and steel ball, product need be adjusted the parallelism of guide rail at guide rail two edge-on tables when installation, and many guide rails of bull machine will be contained in also very difficult centering on the same straight line.
The model utility content
The purpose of this utility model is to overcome the deficiency of existing high-speed straight-line guiding pairs, a kind of high-speed straight-line guiding pairs of interior circulating ball formula is provided, its guiding pairs has designed positioning boss at the slide block back side, establish a benchmark that centering is installed to final assembly, make it easy for installation, improve work efficiency, have also obtained corresponding raising in the kinematic accuracy of guiding pairs and working life.
The purpose of this utility model is achieved like this: the high-speed straight-line guiding pairs is made of guide rail, slide block, back device, rubber dust guard and steel ball, the inboard of slide block is provided with and the suitable Gothic duplex circular ares profile race of guide rail outside sectional shape, and the steel ball of bearing load is arranged in the raceway; Positioning boss has been designed at the slide block back side, slide block is arranged on by steel ball also can be along the guide rail axial motion on the guide rail, be used for making the back device of steel ball revolution back to be fixed on the two ends of slide block, make steel ball do the Infinite Cyclic motion on guide rail along with slide block, the rubber dust guard is fastened on the slide block outermost; Positioning boss has been designed at the slide block back side, centering leveling when being convenient to whole machine installation.
Characteristics of the present utility model: 1, on structural type, adopt in the circulating ball formula, constitute by guide rail, slide block, back device, rubber dust guard and steel ball, designed positioning boss at the slide block back side, established the benchmark of an installation centering to final assembly;
2, on processing link, the high speed slide block requires parallel symmetry with foreign side, and the side, location requires parallel with the raceway groove, reach this point, just increases the materials and the difficulty of processing of slide block, so price increases by 10% than generic linear guiding pairs;
3, on the final assembly link, the client just can beat table centering wall scroll and bull bar linear guide pairs when installation, locating basis is provided also for the assembling of cabinet and guiding pairs, single straight line guiding pairs running precision is improved, and just can guarantee that very easily many linear guide pairies keep high running precision on same straight line, make the operation that device can high-speed smooth;
4, in the maintenance of running precision, improved the linear movement precision of coaster, the ability of colour changing device thermal deformation resistant when long-time the use is improved, more strengthened device, make the complete machine device can guarantee the operation of long high-speed, high precision in starting, shock proof ability when stopping;
5, on working life,, reduced equipment maintenance rate in use, so to be higher than the generic linear guiding pairs working life owing to improved the linear movement precision of guide rail coaster.
The utility model has designed positioning boss at the slide block back side, established the benchmark that centering is installed to final assembly, improved the linear guide pairs assembly precision, the thermal deformation resistant ability improves during long-time the use, more strengthened device in startup, the shock resistance when stopping, the ability of vibration, made complete machine steady when high speed operation, reliable.
The utility model is made of guide rail, slide block, back device, rubber dust guard and steel ball, and installation dimension is little, the precision height, and dress is convenient, has improved work efficiency, and the kinematic accuracy and the working life of guiding pairs also are improved.
