具体实施方式 Detailed ways

如图1-4所示,圆形反向器滚珠螺母端面键槽夹具,用于加工键槽8,其包括V型底座1、V型压板3、销子7、螺栓4和螺帽5,滚珠螺母6依靠外圆夹持在V型底座1和V型压板3之间,并通过螺栓4和螺帽5固定,销子7穿过滚珠螺母6中部的反向器孔,以过盈配合固定在V型底座1的中部,销子7和反向器孔之间为间隙配合,间隙为0.01mm。 As shown in Figure 1-4, the round reverser ball nut end face keyway fixture is used to process the keyway 8, which includes a V-shaped base 1, a V-shaped pressure plate 3, pins 7, bolts 4 and nuts 5, and the ball nut 6 is clamped between the V-shaped base 1 and the V-shaped pressure plate 3 by the outer circle, and fixed by the bolt 4 and the nut 5, and the pin 7 passes through the reverser hole in the middle of the ball nut 6, and is fixed on the In the middle of the V-shaped base 1, there is a clearance fit between the pin 7 and the reverser hole, and the clearance is 0.01mm.

实施中把M3205滚珠螺母6上最中间的圆形反向器孔套进V型底座1中心的销子7上,把滚珠螺母6的外圆柱面和V型上的两个斜面靠实,这时V型的两斜面就限制了螺母X和Z两个方向的移动,同时又限制了螺母X和Z两个轴向的转动。而插入反向器孔的销子因为是以过盈的紧配合固定在V型底座上的,也限制了螺母Y向的移动和Y轴的转动,从而限制了螺母在三维空间的六个自由度,实现了螺母的完全定位。 During the implementation, the middlemost circular reverser hole on the M3205 ball nut 6 is inserted into the pin 7 in the center of the V-shaped base 1, and the outer cylindrical surface of the ball nut 6 and the two slopes on the V-shaped are firmly connected. The two slopes of the V-shape limit the movement of the nut in the X and Z directions, and at the same time limit the rotation of the nut in the X and Z directions. Because the pin inserted into the reverser hole is fixed on the V-shaped base with an interference tight fit, it also limits the movement of the nut in the Y direction and the rotation of the Y axis, thereby limiting the six freedoms of the nut in three-dimensional space. degree, to achieve the complete positioning of the nut.

滚珠螺母上面采用带V型的压板增加了压紧的位置,使压紧更可靠。压板两头采用开口槽结构,可以使螺母的装卸更加方便,同时由于开口槽和螺杆之间有0.5毫米的间隙,可以防止过定位。V型底座下部采用加宽结构以增大底面积,提高夹具的稳定性,上部的宽度正好可以避免加工时与刀具的干涉。底部的两个U型槽用于固定夹具。 The V-shaped pressing plate is used on the ball nut to increase the pressing position and make the pressing more reliable. Both ends of the pressure plate adopt an open slot structure, which can make the loading and unloading of the nut more convenient, and at the same time, there is a gap of 0.5 mm between the open slot and the screw rod, which can prevent over-positioning. The lower part of the V-shaped base adopts a widened structure to increase the bottom area and improve the stability of the fixture. The width of the upper part is just right to avoid interference with the tool during processing. The two U-shaped grooves on the bottom are used to fix the clamps.

本夹具使用时:首先用百分表找正V型底座与机床Y轴平行,通过底座两端的U型槽把整个夹具固定在机床工作台上。再把螺母M3205按说明1中的步骤装入底座,然后装上V型压板,用螺丝压紧。最后在机床上找正好螺母的工件坐标零点,就可以用三面刃铣刀在立式加工中心上加工螺母两端的键槽了。 When using this fixture: first use the dial indicator to align the V-shaped base parallel to the Y-axis of the machine tool, and fix the entire fixture on the machine tool table through the U-shaped grooves at both ends of the base. Then install the nut M3205 into the base according to the steps in Instruction 1, then install the V-shaped pressure plate, and tighten it with screws. Finally, find the zero point of the workpiece coordinates of the nut on the machine tool, and then use the three-side milling cutter to process the keyways at both ends of the nut on the vertical machining center.
