As mentioned above, the Sewing machines 1 of present embodiment comprises work feed drive unit 20.Work feed drive unit 20 comprises a pair of X-axis fixed axis 24,25, X-axis mobile member 40, a pair of Y-axis fixed track 61,62, the moving member 73 of y-axis shift, cloth presser 80 etc.X-axis fixed axis 24,25 is configured in the below of lower shaft 10, and Y-axis fixed track 61,62 is configured in the top of lower shaft 10.X-axis mobile member 40 has and utilizes shank 42～45 fixed station 41 to be bearing in the convex form of lower shaft 10 tops.Therefore, on one side X-axis mobile member 40 can be avoided lower shaft 10, Yi Bian fixed station 41 is moved along X-axis fixed axis 24,25.The moving part 52～55th of X-axis mobile member 40, ball sleeve slides along X-axis fixed axis 24,25.Therefore, X-axis mobile member 40 can move along X-axis fixed axis 24,25 ideally.Be supported in the top of fixed station 41 due to Y-axis fixed track 61,62, therefore, the moving member 73 of y-axis shift can stably move along Y-axis fixed track 61,62.Work feed drive unit 20 can easily make the moving member 73 of y-axis shift stably move by using Y-axis motor, pinion 67 and the so simple structure of tooth bar 68.
The utility model is not limited to above-mentioned embodiment, can carry out various distortion.Below four variation be to change the part of above-mentioned embodiment and share other parts and the structure that obtains.Therefore, the identical component parts mark Reference numeral identical with above-mentioned embodiment described.
With reference to Fig. 6, the first variation is described.As an example of the first fixed track of the present utility model, above-mentioned embodiment has X-axis fixed axis 24,25, and as an example of moving part, above-mentioned embodiment has ball sleeve that is moving part 52～55.Work feed drive unit 120 substitute have X-axis fixed axis 24,25 and have X-axis line slideway 124,125, substitute have moving part 52～55 and have moving part 153,155(other omit diagram).Moving part 153,155 slides along X-axis line slideway 124,125.Therefore, X-axis mobile member 40 moves along X-axis line slideway 124,125.Improved the linearity of the movement on the X-direction of X-axis mobile member 40.
With reference to Fig. 7, the second variation is described.Use in the above-described embodiment a pair of belt pulley 36,39 and endless belt 27 X-axis mobile member 40 is moved along X-direction.Work feed drive unit 220 uses rack and pinion structure that X-axis mobile member 40 is moved along X-direction.X-axis motor 131 is configured in the right back of the fixed station 41 of X-axis mobile member 40.The driving shaft 134 of X-axis motor 131 is forwards outstanding.Driving shaft 134 possesses pinion 135.Tooth bar 100 is fixed on the right corner portion at rear of the upper surface of fixed station 41.Tooth bar 100 be along X-direction extend tabular.Tooth bar 100 is engaged in pinion 135.Pinion 135 rotates with common with the rotation of the driving shaft 134 of X-axis motor 131.Because the tooth bar 100 that is engaged in pinion 135 moves along X-direction, therefore, X-axis mobile member 40 moves along X-direction.Work feed drive unit 220 can directly be converted to the driving force of X-axis motor 131 movement of X-axis mobile member 40.Therefore, X-axis mobile member 40 can move along X-direction reliably.And owing to comparing with above-mentioned embodiment, the parts number of packages of work feed drive unit 220 is less, therefore can make the device integral miniaturization.
With reference to Fig. 8, the 3rd variation is described.In the above-described embodiment, in order to prevent X-axis fixed axis 24,25 deflections, the upper end of rail support member 90 is connected to the section that is supported 29 that is separately positioned on X-axis fixed axis 24,25 central portion and supports being supported section 29 from the below.The X-axis fixed axis of work feed drive unit 320 has the shape that is split to form at least in the lower zone of lower shaft 10.The X-axis fixed axis that is positioned at the front side of work feed drive unit 320 possesses left-hand axis 24A and right-hand axis 24B.Left-hand axis 24A separates in the lower zone of lower shaft 10 at least with right-hand axis 24B.
Rail support member 191,192 is arranged in zone separately.The left end of above-mentioned left side supporting member 21 supporting left-hand axis 24A.The right-hand member of rail support member 191 supporting left-hand axis 24A.The right-hand member of above-mentioned right side supporting member 22 support right side shaft 24B.The left end of rail support member 192 supporting left-hand axis 24A.In the 3rd variation, due to being divided into many, supports the X-axis fixed axis, therefore can prevent the central portion deflection of X-axis fixed axis.In the 3rd variation, though an X-axis fixed axis is divided into two, also can further be divided into many.And, in the 3rd variation, the X-axis fixed axis being illustrated, this X-axis fixed axis also can be applied to the line slideway of the 1st variation.
With reference to Fig. 9, Figure 10, the 4th variation is described.Fig. 9, Figure 10 take the circumstances into consideration to omit the various parts that share with above-mentioned embodiment and illustrate.In Fig. 4, work feed drive unit 20 shown in Figure 5, X-axis fixed axis 24,25 is arranged on the below of lower shaft 10, Y-axis fixed track 61,62 is arranged on the top of lower shaft 10.Fig. 9, work feed drive unit 420 shown in Figure 10 with X-axis fixed axis 24,25 and Y-axis fixed axis 171 described later, 172 the two be arranged on the below of lower shaft 10.
Work feed drive unit 420 possesses X-axis mobile member 140.X-axis mobile member 140 comprises fixed station 141, four shanks 142, four moving parts 168, a pair of Y-axis fixed axis 171,172, mobile supporting mass 160 etc.Fixed station 141 is the board members of shape of being rectangle when overlooking.Fixed station 141 is positioned at the top of lower shaft 10.Four shanks 142 are arranged on four jiaos of fixed station 141.Four shanks 142 extend below four angle verticals of fixed station 141.
Each shank 142 has moving part 168 in the bottom.Moving part 168 is for example ball sleeve cylindraceous.X-axis fixed axis 24,25 is inserted in the hole section (omitting diagram) of each moving part 168.Each moving part 168 slides along X-axis fixed axis 24,25.Therefore, X-axis mobile member 140 can move along X-axis fixed axis 24,25.Fixed station 141 can move along X-direction above lower shaft 10.The lower surface of fixed station 141 is linked to endless belt 27.Therefore, fixed station 141 comes and goes mobile by the movement of endless belt 27 along X-direction.
A pair of shank 142 is relative along Y direction in the left and right sides of the X-direction of fixed station 141.Y-axis fixed axis 171,172 is separately positioned between a pair of shank 142.Y-axis fixed axis 171,172 extends along Y direction.Mobile supporting mass 160 comprises main part 161, bracket part 162,163.Main part 161 is the elongated OBL board members that extend along X-direction.Main part 161 has fixed part 165 at the X-direction central portion.Fixed part 165 is to the outstanding board member in Y direction rear.Bracket part 162 is arranged on the left end side of main part 161.Bracket part 162 is tiltedly below extension (with reference to Figure 10) obliquely left.The top ends of bracket part 162 has guide hole (omitting diagram).Guide hole is along the Y direction setting.The Y-axis fixed axis 171 that is arranged in the left side is inserted into the guide hole of bracket part 162.Bracket part 163 is arranged on the right-hand member side of main part 161.Bracket part 163 is tiltedly below extension obliquely to the right.The top ends of bracket part 162 has guide hole (omitting diagram).Guide hole is along the Y direction setting.The Y-axis fixed axis 172 that is arranged in the right side is inserted into the guide hole of bracket part 163.Therefore, mobile supporting mass 160 can move to Y direction along a pair of Y-axis fixed axis 171,172.The base portion 88 of the bracket part 81 of cloth presser 80 is fixed on the upper surface of fixed part 165 and the upper surface of main part 161.Therefore, mobile supporting mass 160 supports cloth presser 80 for moving along Y direction.X-axis fixed axis 24,25 and Y-axis fixed axis 171,172 all be positioned at than lower shaft 10 position on the lower.Therefore, in the 4th variation, can guarantee fully be used to the space that the various parts such as X-axis mobile member 140 are set above lower shaft 10.
