A kind of Wedge type press plate mechanism
Technical field
The utility model relates to a kind of machining fixed mechanism, especially relates to a kind of Wedge type press plate mechanism.
Background technology
Pressing plate in the mechanical processing industry all adopts bolt and nut to compress at present, need be connected and fixed through T type groove and lathe table top, when processing work (like workpiece size) receives the restriction of platen face size, then can't workpiece be installed through T type groove.Accomplish processing for often addressing this problem through changing more large-scale lathe, increased cost of processing.Its T type groove groove width of different in addition lathes is different, causes on different lathes, will being equipped with different pressing plates accordingly.In a word, this type clamp operation inconvenience, waste time and energy.Therefore, the scope restriction of pressing plate being installed for fear of T type groove and improve property easy for installation has designed a kind of novel wedge press plate mechanism; To reduce in the machining lathe table top to the influence of pressing plate; Reduced instructions for use to lathe, can be more efficient, accomplish Work-sheet pressing more easily.
The utility model content
The purpose of the utility model is exactly to provide a kind of for the defective that overcomes above-mentioned prior art existence can workpiece be compressed in lathe table top arbitrary plane position; And need not to be connected with the lathe table top through bolt and nut, and efficiently, Wedge type press plate mechanism easily.
The purpose of the utility model can realize through following technical scheme: a kind of Wedge type press plate mechanism is characterized in that this press plate mechanism comprises brace table, lower bolster, end face fixed head, ejector, puller bolt, push rod and top board; Described brace table side-lower has short slot; Lower bolster is connected the brace table below, and the end face fixed head is connected the side that brace table has short slot, and described ejector is arranged in the short slot; Be connected with the puller bolt that passes the end face fixed head; Described push rod lower end is passed brace table and is connected with ejector, and the push rod upper end is connected with top board one end, and described top board middle part is rotatably connected through pin and brace table.
Described ejector comprises guide runner, tapered wedges, guide pin reach and go up tapered wedges down; Described guide runner is fixed through screw and lower bolster; The described side of tapered wedges down is connected with puller bolt, and this time tapered wedges below is provided with groove, and following tapered wedges is connected with the guide runner sliding-contact through groove; The lower end of described guide pin is connected with following tapered wedges; Its upper end is connected with last tapered wedges, and the described inclined-plane of going up tapered wedges is connected with the inclined-plane sliding-contact of following tapered wedges, and the upper end of last tapered wedges is connected with push rod.
Be with spring on the described guide pin, the lower end of this spring is connected with guide runner, and the upper end is connected with last tapered wedges.
Described top board comprises link and free end, and link is connected with push rod, and the free end below is provided with anti-briquetting.
Compared with prior art, the utlity model has following advantage:
1, can carry out the conversion of power through the mode that tights a bolt; The power of tightening level is converted into downward pressure; And discarded and adopted T type bolt and the fixing mode of lathe table top to come workpiece pressing; And the pressed altitude range of adjustment pressing plate that can be random, thus installation requirement reduced to lathe, guaranteed the versatility reliability and the interchangeability of pressing plate;
2, need not come workpiece pressing through the mode that bolt and nut connects the lathe table top, accomplished in lathe table top arbitrary plane position can workpiece pressing purpose;
3, can extensively apply in the various universal machine processing tools, it is compared common pressing plate limitation and has obtained improving greatly, can be more efficient, and be the machining service more easily.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of Wedge type press plate mechanism, this press plate mechanism comprise brace table 14, lower bolster 11, end face fixed head 7, ejector, puller bolt 9, push rod 2 and top board 1.Brace table 14 side-lowers have short slot, and lower bolster 11 is connected brace table 14 belows, and end face fixed head 7 is connected the side that brace table 14 has short slot.Ejector is arranged in the short slot, is connected with the puller bolt that passes end face fixed head 79.Push rod 2 lower ends are passed brace table 14 and are connected with ejector, and push rod 2 is controlled its guiding with brace table 14 through the square hole matched in clearance.Adopt the orthodrome transition to be connected between push rod 2 upper ends and top board one end, top board 1 middle part through pin 12 and brace table 14 be rotatably connected.
Ejector comprises guide runner 8, tapered wedges 5, guide pin 4 reach and go up tapered wedges 15 down; Guide runner 8 is fixing with lower bolster 11 through soket head cap screw 10; The side of following tapered wedges 5 is connected with puller bolt 9; This time tapered wedges 5 belows are provided with groove, and following tapered wedges 5 is connected with guide runner 8 sliding-contacts through groove.The lower end of guide pin 4 is connected with following tapered wedges 5, and its upper end is connected with last tapered wedges 15, and the inclined-plane of last tapered wedges 15 is connected with the inclined-plane sliding-contact of following tapered wedges 5, and the upper end of last tapered wedges 15 is connected with push rod 2.Following tapered wedges 5 cooperates with guide runner 8 straight troughs through groove and moves; Through guide pin 4 rising of leading, when backhaul, carry out backhaul between last tapered wedges 15 and the guide runner 8 through spring 6.
Be with spring 6 on the guide pin 4, the lower end of this spring 6 is connected with guide runner 8, and the upper end is connected with last tapered wedges 15.
Top board 1 comprises link and free end, and link is connected with push rod 2, and the free end below is provided with anti-briquetting 13, and anti-briquetting 13 is connected with top board 1 through screw.
During use, the puller bolt 9 on the end face fixed head 7 of screwing will descend tapered wedges 5 to push away forward, and tapered wedges 15 is moved up along guide pin 4, and drive push rod 2 and upwards withstand top board 1, because leverage, the free end of top board 1 can be with Work-sheet pressing.In bolt backhaul rotation, spring 6 retractions, last tapered wedges 15 moves down, following tapered wedges 5 retractions, top board 1 loosens workpiece.
