The specific embodiment
Please refer to the drawing 1, present embodiment has disclosed 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 for carrying the upper surface 111 of workpiece.Cover assembly 120 is provided with the pressing piece 130 of configuration relative to 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 deformations, the elastic restoring force on it acts on workpiece, thus can by workpiece firm by being pressed on workbench.On cover assembly, be provided with above-mentioned pressing piece 130, because pressing piece 130 is provided with the flexible elastomer with elastic deformation ability, thereby can be by the workpiece with rough surface stably by being pressed on workbench 110, and can make workpiece can not produce vibration in cutting process, and then improve the machining accuracy of workpiece.
Further, cover assembly 120 comprises the boot main body 121 that is connected with above-mentioned pressing piece 130, the shield stand 122 fixing with workbench 110 and is connected with boot main body 121 and can the pivotal arm 123 of pivotable in shield stand 122.By driving pivotal arm 123 can make boot main body 121 in approaching the first operating position of workbench 110 and away from the second operating position of workbench 110.When boot main body 121 is during in the first operating position, the duty of desk-top sweep-saw 100 in cut workpiece, under this state, along with the feed distance of workpiece increases, pressing piece 130 can progressively be connected on surface of the work; When boot main body 121 is during in the second operating position, desk-top sweep-saw 100 is in off working state, and under this state, 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, adjacent setting between pressing plate 1211 and 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, between boot main body 121 and pressing piece 130, can be fixedly connected with by between draw-in groove and buckle, can also be by dismountable connection between guide groove and guide rail, in addition, can also realize in other mode being connected and fixed between boot main body 121 and pressing piece 130, be not specifically limited herein.
Please refer to the drawing 2 is to Fig. 5, and flexible elastomer is M * N array arrangement, and wherein, M is more than or equal to 1 positive integer, and N is also for being more than or equal to 1 positive integer.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, so long as can meet, has the corresponding function towards the elastic restoring force of workpiece deformation when it is pressed on workpiece.
Please refer to the drawing 2, for the cutaway view of A-A place pressing piece embodiment 1 in Fig. 1, from cutaway view, is provided with 1 * 12 and the longitudinal flexible elastomer 131 of arrayed on the pressing piece 130 of present embodiment, this flexible elastomer 131 is flexible sheets.Wherein, the width of pressing piece 130 width similar with the width to pressing plate 1211 or that be less than pressing plate 1211 is advisable.
The length scale of pressing piece 130 has determined that it is pressed on the stability on workpiece, and the length of pressing piece 130 is longer, and its stability being pressed on workpiece is higher, but in this 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 being 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 dynamics that compresses on workpiece and the surface roughness of workpiece to be processed, when the thickness of flexible sheets is thicker, its to workpiece to compress dynamics larger, contact area increase due to single flexible sheet and surface of the work, therefore, its having relatively high expectations to the surface flatness of pressed workpiece.Identical, when the thickness of flexible sheets is thinner, its dynamics that compresses to workpiece will correspondingly diminish, and because the contact area of single flexible sheet and surface of the work diminishes, therefore, its requirement to the surface flatness of pressed workpiece is lower.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 has also determined its dynamics that compresses to workpiece, when the angle a of flexible sheets and worktable upper surface 111 is larger, its to workpiece to compress dynamics less; When the angle a of flexible sheets and worktable upper surface 111 more hour, its to workpiece to compress dynamics larger.Angle a scope between flexible sheets and worktable upper surface 111 is preferably 30 degree-85 degree.
Please refer to the drawing 3, for the cutaway view of A-A place pressing piece embodiment 2 in Fig. 1, from cutaway view, is provided with the flexible elastomer 231 of 2 * 12 arrayed on the pressing piece 230 of present embodiment, 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 set with embodiment 1 in the setting of relevant parameter similar, do not repeat them here.
Please refer to the drawing 4, cutaway view for A-A place pressing piece embodiment 3 in Fig. 1, from cutaway view, on the pressing piece 330 of present embodiment, be 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 to the surface flatness of pressed workpiece, but meanwhile, also reduced the compress dynamics of flexible column to workpiece.Wherein, the diameter range of flexible column is preferably 1mm-10mm.
Please refer to the drawing 5, for the cutaway view of A-A place pressing piece embodiment 4 in Fig. 1, from cutaway view, is provided with the flexible elastomer 431 of arrayed on the pressing piece 430 of present embodiment, this flexible elastomer 431 is the combination of flexible sheets and flexible column.The flexible sheets described in embodiment 1 of comparing, this flexible elastomer 431 can increase to workpiece compress dynamics time, can also reduce the requirement of the surface flatness of workpiece.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
