Description
Technical field
The present invention relates to furniture processing technology, be specifically related to a kind of column table leg cylindrical grinding clamping device.
Background technology
The selection of furniture material, consider processing technology, quality and presentation quality, economy, intensity, decorative surface.In antique traditional furniture manufactures, solid wood is the main material of Furniture manufacture, particularly the Axle Parts such as table leg adopts solid wood manufacture usually, solid wood has good performance on processing technology, quality, intensity, decorative surface, but solid wood manufactures furniture by substantial timber, be unfavorable for environmental protection, production cost is high.Therefore now a large amount of columnar metal cylinders such as alloys that adopt replace, but to the cutting of columnar metal cylinder class, particularly when carrying out ornamental fine finishining to foreign round, the radial anti-pressure ability of columnar metal cylinder is poor.Traditional clamping device is taked to clamp from column cylindrical outer, be easy to processed column cylinder is out of shape in process, difficulty of processing is large, be difficult to the processing carrying out high-decoration above, therefore be badly in need of one to fix column cylinder class Workpiece clamping, the clamping device of the distortion of workpiece can not be caused again.
Summary of the invention
The invention provides a kind of column table leg cylindrical grinding clamping device, to solve in column cylinder class furniture Excircle machining process, clamping device easily causes by the problem of column cylinder class furniture distortion, to carry out the processing of various high-decoration to column cylinder class furniture cylindrical and can not cause distortion.
This programme is as follows: column table leg cylindrical grinding clamping device, comprise drag hook, jaw and the matrix be fixed in frame, matrix one end cylindrical is cone inclined-plane, jaw has the inclined-plane parallel with matrix cylindrical cone inclined-plane, the inclined-plane of described jaw is at the cone contact of incline plane of matrix cylindrical surrounding and matrix, fluted outside described jaw, described jaw is closed up by the collar in groove, described base shaft is to there being through hole, described drag hook is inner at through hole, one end that drag hook extends in matrix through hole outside has drag hook to hook cap, described drag hook hook cap and jaws contact control the axially-movable of jaw, the threaded engagement on screwed hole and center pulling shaft is had at the drag hook other end, described center pulling shaft empty set is on matrix through hole and to extend to the through hole of matrix outside, center pulling shaft is provided with axial limit structure.
This programme operation principle is as follows:
In the course of work, gripping portions is stretched into clamped table leg inner chamber, pivot pulling shaft macro-axis one end, because center pulling shaft and drag hook are taked to be threaded, center pulling shaft rotates will cause the axially-movable of drag hook, during work, drag hook be moved to pulling shaft direction, center.Coordinate with jaw because drag hook hooks cap, when drag hook axially-movable, jaw axially-movable will be driven.Jaw inside is inclined-plane, the parallel-slope that matrix outer has jaw inner chamfer corresponding, therefore jaw will produce relative motion with matrix, due to inclined-plane, jaw will produce the motion expanded outwardly, thus clamping work pieces, because be from inside to outside exert a force, can conveniently to column cylinder class furniture Excircle machining, not yielding.
In like manner during end-of-job, have collar by jaws close in the groove due to jaw periphery, therefore, reversely rotate center pulling shaft, jaw is by inward collapsible, and jaw has larger gathering power, thus is unloaded from column table leg cylindrical grinding clamping device by workpiece.
Further, matrix and drag hook mating part, matrix has guider screw, and drag hook axially has gathering sill, and described gathering sill and guider screw coordinate.The existence of guider screw and gathering sill, when can prevent pivot pulling shaft, drag hook rotates together with the pulling shaft of center, can not relative motion, leads to drag hook.
Further, the collar quantity on jaw is no less than two, can increase elasticity and the stability of jaw inward collapsible, for convenience detach.
Further, described collar is elastic tape or spring collar, and elastic force is large, can conveniently unload.
Further, described position limiting structure comprises banking stop and nut, center pulling shaft is multidiameter, little axle one end have coordinate with the screwed hole of drag hook external screw thread, the limited bit slice in described matrix through hole aperture place, little axle sleeve enters in spacing film perforation, banking stop and nut to center pulling shaft axial limiting, replacing for convenience detach.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is hook structure schematic diagram;
Pulling shaft structural representation centered by Fig. 3.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: matrix 1, jaw 2, workpiece 3, banking stop 4, center pulling shaft 5, nut 6, collar 7, drag hook 8, guider screw 9, gathering sill 10, drag hook hook cap 11, macro-axis 12, little axle 13.
Embodiment is basic as accompanying drawing 1, 2, shown in 3: the present invention includes drag hook 8, be fixed on the matrix 1 in frame and jaw 2, matrix 1 inside is provided with through hole, drag hook 8 is inner at through hole, one end that drag hook 8 extends in matrix 1 through hole outside has drag hook to hook cap 11, drag hook hooks cap 11 and coordinates with jaw 2, the threaded engagement on screwed hole and center pulling shaft 5 is had at drag hook hook cap 11 other end, center pulling shaft 5 is hinged on matrix 1 through hole and to extend to the through hole of matrix 1 outside, articulated manner herein, can take: center pulling shaft 5 is set to multidiameter, little axle 13 one end have coordinate with the screwed hole of drag hook 8 external screw thread, described matrix 1 through hole aperture place is fixed with banking stop 4, little axle 13 packs in banking stop 4 hole, banking stop 4 and nut 6 pairs of center pulling shaft 5 axial limitings.
Jaw 2 coordinates with matrix 1 in matrix 1 outside, and the inclined-plane of matrix 1 outside is parallel with the inclined-plane of jaw 2 inside, and jaw 2 periphery is fluted, and jaw 2 is closed up by the collar 7 in groove.During work, jaw 2 part is stretched into workpiece 3 inner, macro-axis 12 one end of pivot pulling shaft 5, drag hook 8 is moved to center pulling shaft 5 direction, drive jaw 2 to move, thus cause jaw 2 and matrix 1 relative motion, because jaw 2 and matrix 1 contact surface are inclined-plane, drive jaw 2 expands outwardly by matrix 1, thus clamping work pieces 3.
Matrix 1 and drag hook 8 mating part, drag hook 8 axially has gathering sill 10, matrix has guider screw 9 stretch in gathering sill, and when pivot pulling shaft 5, guider screw 9 is mobile in gathering sill 10, leads, prevent drag hook 8 from rotating together with center pulling shaft 5 to drag hook 8.
At the collar 7 of the groove of jaw 2 periphery, when quitting work, reverse rotation center pulling shaft 4, under the active force of collar 7, it is jaw 2 inward collapsible, collar 7 can adopt elastic tape or spring collar as required herein, if adopt spring collar when load forces is larger, adopts elastic tape when load forces is less.Length according to jaw 2 evenly can arrange plural collar 7, increases stability and the elasticity of jaw 2 gathering.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
