Detailed description of the invention
Please refer to the drawing 1, present embodiment discloses a kind of desk-top sweep-saw 100, and this desk-top sweep-saw 100 comprises workbench 110 and is arranged on the cover assembly 120 on workbench 110.Workbench 110 has the upper surface 111 for carrying workpiece.Cover assembly 120 is provided with the pressing piece 130 be oppositely disposed with workbench 110.Pressing piece 130 is provided with the flexible elastomer 131 with elastic deformation ability.When above-mentioned pressing piece 130 is pressed on workpiece, flexible elastomer 131 compressive deformation, the elastic restoring force on it acts on workpiece, thus can by pressing firm for workpiece on the table.Cover assembly is provided with above-mentioned pressing piece 130, because pressing piece 130 is provided with the flexible elastomer with elastic deformation ability, thus the workpiece of rough surface will can be had stably by being pressed on workbench 110, and workpiece can be made in cutting process vibration can not to be produced, and then improve the machining accuracy of workpiece.
Further, cover assembly 120 comprises the boot main body 121, the shield stand 122 fixing with workbench 110 that are connected with above-mentioned pressing piece 130 and to be connected with boot main body 121 and can the pivotal arm 123 of pivotable in shield stand 122.Boot main body 121 can be made to be in the first operating position close to workbench 110 and the second operating position away from workbench 110 by driving pivotal arm 123.When boot main body 121 is in the first operating position, desk-top sweep-saw 100 is in the duty of cut workpiece, and in this case, along with the feed distance of workpiece increases, pressing piece 130 can progressively abut on the surface of the workpiece; When boot main body 121 is in the second operating position, desk-top sweep-saw 100 is in off working state, and in this case, operating personnel can change saw blade easily.In addition, boot main body 121 is also included in the process of workpiece feeding, for compressing the pressing plate 1211 of workpiece, is disposed adjacent between pressing plate 1211 with pressing piece 130.
In addition, one-body molded manufacture between boot main body 121 and pressing piece 130, it is to be noted, in other embodiments, by being fixedly connected with between draw-in groove with buckle, can also can be connected by dismountable between guide groove with guide rail, in addition between boot main body 121 with pressing piece 130, being connected and fixed between boot main body 121 and pressing piece 130 can also be realized in other manners, be not specifically limited herein.
Please refer to the drawing 2 to Fig. 5, flexible elastomer is M × N array arrangement, wherein, M be more than or equal to 1 positive integer, the positive integer of N also for being more than or equal to 1.In addition, this flexible elastomer can be flexible sheets or flexible column, or the combination of flexible sheets and flexible column.The material of flexible elastomer can be plastic material, it is to be noted, in other embodiments, the material of flexible elastomer can also be quality of rubber materials, the material of flexible elastomer is not specifically limited, and has towards the corresponding function of the elastic restoring force of workpiece deformation as long as can meet when it is pressed on workpiece.
Please refer to the drawing 2 is the sectional view of A-A place pressing piece embodiment 1 in Fig. 1, and from sectional view, the pressing piece 130 of present embodiment is provided with 1 × 12 and the flexible elastomer 131 of longitudinal arrayed, this flexible elastomer 131 is flexible sheets.Wherein, the width of pressing piece 130 is advisable with width that is similar to the width of pressing plate 1211 or that be less than pressing plate 1211.
The length scale of pressing piece 130 determines it and is pressed on stability on workpiece, and namely the length of pressing piece 130 is longer, and its stability be pressed on workpiece is higher, but simultaneously, the resistance that workpiece passes through pressing piece 130 will increase; Contrary, if the length of pressing piece 130 is shorter, the resistance that workpiece passes through pressing piece 130 will reduce, but its stability be pressed on workpiece weakens relatively.In a preferred embodiment, the length range of pressing piece 130 is preferably 5mm-50mm.
The thickness of flexible sheets is determined according to the surface roughness of the dynamics that compresses on workpiece and workpiece to be processed, namely the thickness when flexible sheets is thicker, its to workpiece to compress dynamics larger, because the contact area of single flexible sheet and surface of the work increases, therefore, it is higher to the requirement of the surface flatness of pressed workpiece.Identical, when the thickness of flexible sheets is thinner, it will correspondingly diminish to the dynamics that compresses of workpiece, and because the contact area of single flexible sheet and surface of the work diminishes, therefore, it is lower to the requirement of the surface flatness of pressed workpiece.In a preferred embodiment, the thickness range of flexible sheets is preferably 0.5mm-4.0mm.
In addition, the size of the angle a of flexible sheets and worktable upper surface 111 also determines it and compresses dynamics to workpiece, namely when the angle a of flexible sheets and worktable upper surface 111 is larger, its to workpiece to compress dynamics less; When flexible sheets and worktable upper surface 111 angle a more hour, its to workpiece to compress dynamics larger.Angle a between flexible sheets and worktable upper surface 111 ranges preferably from 30 degree-85 and spends.
Please refer to the drawing 3, be the sectional view of A-A place pressing piece embodiment 2 in Fig. 1, from sectional view, the pressing piece 230 of present embodiment be provided with the flexible elastomer 231 of 2 × 12 arrayed, this flexible elastomer 231 is flexible sheets.Wherein, in present embodiment and following embodiment, in the thickness of flexible sheets and the width of pressing piece 230 and the setting of length scale and embodiment 1, the setting of relevant parameter is similar; The size of the angle a of flexible sheets and worktable upper surface sets with the setting of relevant parameter in embodiment 1 similar, does not repeat them here.
Please refer to the drawing 4, for the sectional view of A-A place pressing piece embodiment 3 in Fig. 1, from sectional view, the pressing piece 330 of present embodiment is provided with the flexible elastomer 331 of 5 × 8 arrayed, this flexible elastomer 331 is flexible column, the flexible sheets described in embodiment 1 of comparing, and this flexible column can reduce the requirement of the surface flatness to pressed workpiece, but meanwhile, also reduce flexible column and dynamics is compressed to workpiece.Wherein, the diameter range of flexible column is preferably 1mm-10mm.
Please refer to the drawing 5, be the sectional view of A-A place pressing piece embodiment 4 in Fig. 1, from sectional view, the pressing piece 430 of present embodiment be provided with the flexible elastomer 431 of arrayed, this flexible elastomer 431 is the combination of flexible sheets and flexible column.To compare the flexible sheets described in embodiment 1, this flexible elastomer 431 can increase to workpiece compress dynamics while, the requirement of the surface flatness of workpiece can also be reduced.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
