The specific embodiment
The utility model is described in further detail with preferential embodiment below in conjunction with accompanying drawing.
For the convenience of describing, among the preferential embodiment in conjunction with desk type electric tools a kind of exemplary tool--diagonal cutting saw is set forth creating conception of the present utility model.
Usually desk type electric tools comprises an operating position, as shown in Figure 1; Relatively, desk type electric tools also has a position of rest, as shown in Figure 2.
As shown in figs. 1 and 3, desk type electric tools herein is a diagonal cutting saw, comprise support 2, support one end is fixedlyed connected with pedestal 1 or is flexibly connected, saw 3 comprises saw blade 31, motor 32, decides guard shield 34 and movable shield 33, and saw blade 31 is connected with motor 32 by saw blade axis 312, is provided with first jockey 6 at support 2 near saw 3 one ends, saw blade 31 is along the D of view field of saw blade axis 312 directions, and this first jockey 6 to small part is positioned at this region D.
Decide guard shield 34 and be fixedly connected on motor 32 or support 2 etc., 33 of movable shield are articulated in decides also can rotate on the guard shield 34, connecting rod 331 1 ends that connect movable shield 33 are fixed on first jockey 6, the other end is fixed on the movable shield 33, the movement locus of guide pin bushing 8 when moving up and down in order not influence saw 3, connecting rod 331 are designed to crooked herein.When diagonal cutting saw was positioned at position of rest, movable shield 33 was protected the sawtooth of saw blade 313, and when diagonal cutting saw was positioned at the operating position, connecting rod 331 drove movable shield 33 around saw blade axis 312 rotations, and movable shield 33 is opened, and sawtooth exposes.Pedestal 1 includes base 5 and workbench 4 placed on it, workbench 4 can rotate relative to base 5, can place workpiece to be processed 13 on the workbench 4, also is provided with guardrail 17 on workbench 4, workpiece 13 is resisted against on the guardrail 17, and motor 5 is used for driving 4 pairs of workpieces to be processed 13 of saw blade and processes.
In order to make saw 3 can return position of rest from the operating position automatically, first jockey 6 can also comprise the flexible member 10 of reset response.Being provided with of flexible member 10 can be adopted diverse ways, for example an end of flexible member 10 can be arranged in the guide pin bushing 8, and the other end is arranged in the support 2; Also can be resisted against on the guide pin bushing 8 by an end, the other end is resisted against on the support 2; Perhaps flexible member 10 is enclosed within on the guide rod 7,8 of guide pin bushings pass guide rod 7, and to be pressed in flexible member 10 first-class.Flexible member 10 herein can be back-moving spring or other similar substitutes, and flexible member 10 can be one or more.Certainly the position of this guide rod 7 and guide pin bushing 9 is provided with and also can conversely guide rod 7 be arranged on the saw 3, and guide pin bushing 8 is arranged on the support 2.And this guide rod 7 and guide pin bushing 9 also can adopt other alternative means, for example railroad etc.
As shown in Figures 2 and 3, among the preferential embodiment, support 2 is provided with two parallel guide rods and forms guide rod 7, and the face A that two parallel guide rods 7 constitute is parallel with saw blade face B, and it is near as far as possible that the distance between two plane A and B is provided with; At vertical direction the median plane C of vertical saw blade 313 is arranged, center line P1 and saw blade centre bore 9, the first jockeys 6 relative median plane C that this median plane has comprised two guide rods are symmetrical distribution.
It is in order to make the jockey 6 of winning as far as possible near saw blade working region or saw blade centre bore 9 that guide rod 7 so is provided with, thereby improves the rigidity and the cutting accuracy of desk type electric tools.Certainly, also can be with the 6 similar settings of first jockey, be roughly such as first jockey, 6 relative median plane C and be symmetrically distributed or face A that two parallel guide rods 7 constitute and saw blade face B almost parallel etc., the basis of similar variation all is under the approaching prerequisite of considering first jockey 6 and saw blade working region or saw blade centre bore 9 tried one's best, the similar arrangement that synthesis tool rigidity and cutting accuracy and mounting process etc. are done.
Herein, first jockey 6 can partly be positioned at saw blade along the axial D of view field of saw blade, also can all be positioned at the D of this view field, and, in order to obtain excellent effect, the center line P1 of first jockey 6 or first jockey 6 or center are arranged to as far as possible near saw blade centre bore 9 or saw blade working region.
Simultaneously, for convenience saw 3 is transformed into the operating position from position of rest, can also adds operating lever 11, an end of operating lever 11 is connected on the support 2 by pivot 16 pivots, and operating lever 11 can center on the fulcrum 14 that is convexly set on the guide pin bushing 8 do lever motion.
When needs with saw 3 when position of rest is transformed into the operating position, pressing operation lever 11, operating lever 11 is done lever motion around fulcrum 14, because fulcrum 14 is arranged on the guide pin bushing 8, with the guide pin bushing 8 of the saw 3 that is being connected along guide rod 7 toward pressing down, connecting rod 331 drives movable shield 33 and opens it, and compression elastic element 10 has just been realized the lengthwise movement of saw 3 relative pedestals 1 simultaneously.When saw 3 work finish, discharge the operating physical force that is applied on the operating lever 11, flexible member 10 just resets to saw 3 position of rest as shown in Figure 5.
Fig. 4 is the schematic diagram of the saw that slides, how this slip saw has compared a pair with diagonal cutting saw can make the relative workbench of saw do the kinematic pair of horizontal slip--second sliding connecting device 12, this second sliding connecting device 12 can be arranged between support 2 and the saw 3, also can be arranged on (not shown) between support 2 and the pedestal 1.The working range that is arranged so that saw blade 31 cut workpiece of this second sliding connecting device 12 is increased.Herein, first jockey 6 is arranged between the saw and second sliding connecting device 12 and near saw blade centre bore 9 places, operating lever 11 1 end pivots are connected on second sliding connecting device 12, and the fulcrum 14 of operating lever 11 is positioned on first jockey 6.In the saw rigidity of increase sliding, the level that has realized saw 3 relative pedestals 1 with move both vertically.
Certainly, creating conception of the present utility model can also be applied on other similar table tools such as cutting machine, and in order to improve the rigidity of table tool, its operation principle is same as above.
