The specific embodiment
Referring to Fig. 1 to Fig. 4, at a kind of monoblock cast industrial sewing machine casing provided by the invention, comprise that a body 1 and that is used for installing machine core is used for installing the base plate 2 of replaceable working panel 10, described body 1 forms with described base plate 2 integrally castings, be formed with support protrusion section 3 on the described base plate 2, the top of described lug boss 3 is provided with the origin reference location face 31 that is suitable for installment work panel 10.Body 1 among the present invention is be used to main cassette mechanism structure is installed, and these cassette mechanism structures and body construction belong to the mature technology of this area, and improvements of the present invention do not lie in this, therefore, its structure are repeated no more.Main improvements of the present invention are, with body 1 and base plate 2 integrally castings, can guarantee like this precision between head and the working panel, make it be difficult for being shifted.In order to guarantee the installation of working panel, the present invention arranges lug boss 3 at base plate 2, and the top of lug boss 3 is processed to form origin reference location face 31, and working panel 10 guarantees flatness take described origin reference location face 31 as installation base surface.Casing is after casting is finished, and only need to carry out to the end face of lug boss 3 fine finishining can satisfy working panel 10 needed installation accuracies.Because 10 tops with lug boss 3 of working panel contact, thereby having guaranteed that the most of oil lacquer painting of base plate 2 is long-pending can by scratch, not prevent from getting rusty.The area of lug boss 3 is the gross areas that will be far smaller than the upper surface of base plate in the present invention, reduces accurately machined purpose from satisfying the present invention.The gross area of origin reference location face 31 is less than 30% of described base plate 2 top surface area on the described lug boss 3, and preferred version can be 2%, 4%, 5% etc.
Referring to Fig. 1 to Fig. 4, further, described lug boss 3 is for being formed in the protruding ridge 3 of strip shape on the described base plate 2 in above-described embodiment provided by the invention, and the top on the described protruding ridge 3 arranges described origin reference location face 31.Present embodiment is the protruding ridge structure that elongated strip shaped is set at the middle part of base plate 2, and the cross section on this protruding ridge 3 can be rectangle or trapezoidal.End face processing for this protruding ridge 3 is convenient.On the protruding ridge 3 that working panel 10 leans on surely, thereby realize the location.
The protruding ridge of present embodiment is comprised of two parts, and wherein a part is for being positioned at the straightway at base plate 2 middle parts, and another part is the periphery that is positioned at the U-shaped hollow-out parts at base plate 2 middle parts, and two parts link together, and consist of a harpoon shape structure.These protruding ridge are that several mm wides and several millimeter are high, are generally the 3-10 millimeter.Thereby be beneficial to process tool along vertically processing convenient processing.
Referring to Fig. 1 to Fig. 4, in above-described embodiment provided by the invention, further, be provided with fixing hole 32 on the described protruding ridge 3.Described fixing hole 32 can be screwed hole, thus the convenient screw that uses.Working panel 10 is fixed by screws on the protruding ridge 3, thereby can prevent that working panel 10 is shifted or beat in the centre.
Referring to Fig. 1 to Fig. 4, further, the periphery of described base plate 2 forms the gulde edge 4 that is suitable for installment work panel 10 in above-described embodiment provided by the invention, and the end face of described gulde edge 4 is provided with origin reference location face 41.The present invention is used for the periphery of support performance panel 10 at the gulde edge 4 of the periphery processing one circle small size of base plate 2.The origin reference location face 41 of gulde edge 4 is consistent with the origin reference location face on the protruding ridge 3, thereby has guaranteed the flatness that working panel 10 is installed.Simultaneously, described gulde edge 4 has also played the effect of guiding, makes things convenient for the installation of working panel 10.
Referring to Fig. 1 to Fig. 4, in above-described embodiment provided by the invention, further, be formed with on the described gulde edge 4 and be suitable for the draw-in groove 42 that matches with working panel 10 upper clamping hooks 101.Described draw-in groove 42 is used for steady job panel 10, thereby both can be linked together fast.
Referring to Fig. 5, in another kind of embodiment provided by the invention, the described protruding ridge 3 is many, and many described protruding ridge 3 are distributed on the described base plate 2.The described protruding ridge 3 can be many arranges side by side, and also can be every has multi-segment structure to consist of.Main purpose is in order can better to play the effect of support to working panel 10, to guarantee its flatness, satisfying again the little requirement of fine finishining area simultaneously.
Referring to Fig. 6, in another embodiment provided by the invention, described lug boss 3 is a plurality of projections, and described projection is distributed on the described base plate 2.Described lug boss 3 also can also be projection formula structure, and the end face of projection forms the origin reference location face.This projection can play the effect of support equally.
Referring to Fig. 7, in another embodiment provided by the invention, described lug boss 3 is the grating texture of crisscross formation.This grating texture also can be realized the supporting role to working panel 10, and can reduce the fine finishining area.
In the embodiment of a kind of monoblock cast industrial sewing machine provided by the invention, comprise casing, be installed in movement in the described casing, be installed in the replaceable working panel 10 on the described casing and support the frame of described casing, described casing is the described casings of the various embodiments described above.
