Description

A kind of ball screw support location structure
Technical field
The utility model relates to a kind of location structure, and specifically a kind of ball screw support location structure, is specially adapted to vertical lathe, belongs to the annex of plant equipment.
Background technology
Vertical car is mainly used in processing that diameter is large, length is short is large-scale, heavy workpiece and be difficult for the workpiece of clamping on horizontal lathe, in the satisfied situation of tactical diameter, too heavy workpiece is difficult for clamping at sleeping carriage, due to dead weight, machining accuracy is had to impact, adopt vertical car to address the above problem.
In prior art, traditional ball screw support is that bolt and taper pin are fixed, and bolt and taper pin moment are excessive, and support has slight movement, and ball screw backlass is excessive, affects precision.
Summary of the invention
The utility model is for above-mentioned technical problem, and a kind of simple in structure, ingenious, rational a kind of ball screw support location structure is provided, and this structure can realize stable, firmly in ball screw support motion process.
The technical scheme providing according to the utility model: a kind of ball screw support location structure, comprises ball screw support, ball screw, ram; Feature is: also comprise locking nut, spacer, angular contact ball bearing, slide and alignment pin; Described ball screw is arranged on slide, described ball screw for one end pair of horns contact ball bearing, spacer and locking nut be fixed on slide, the described ball screw other end is connected with described ball screw support, utilize ball screw support that ball screw is connected with ram, in the middle of support and ram, add an alignment pin, alignment pin one end is fixed on ram, and the other end is fixed on support, effectively fixed support.
Described ball screw support connects being separately fixed on ram by bolt and taper pin up and down of ram at alignment pin.
The utility model is simple in structure, ingenious, reasonable, improves machining accuracy; Can realize stable, firmly in ball screw support motion process; Thereby reach, control the effect that ram slides up and down.
Accompanying drawing explanation
Fig. 1 is structural representation front view of the present utility model.
Fig. 2 is structural representation top view of the present utility model.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As Figure 1-Figure 2, locking nut 1, spacer 2, angular contact ball bearing 3, slide 4, ball screw 5, ball screw support 6, ram 7, bolt 8, alignment pin 9 and taper pin 10.
As shown in Figure 1, the utility model is a kind of ball screw support location structure, described ball screw 5 one end utilize pair of horns contact ball bearing 3, spacer 2 and locking nut 1 to be fixed on slide 4, ball screw 5 other ends are connected with described ball screw support 6, utilize ball screw support 6 that ball screw 5 is connected with ram 7.
Described ball screw support 6 connects the upper and lower of ram at alignment pin, then is separately fixed on ram 7 by bolt 8 and taper pin 10, and bolt 8 is excessive with taper pin 10 moments, and support 6 has slight movement, and ball screw 5 backlasses are excessive, affect precision.In the middle of support 6, add an alignment pin 9 again, alignment pin 9 one end are fixed on ram 7; Effectively fixed support.
The utility model comprises slide, be arranged on the ball screw on slide, described ball screw utilizes pair of horns contact ball bearing, spacer and locking nut to be fixed on slide, and recycling ball screw support makes ball screw be connected with ram, thereby reach, controls the effect that ram slides up and down.The utility model is simple in structure, ingenious, reasonable, improves machining accuracy; Can realize stable, firmly in ball screw support motion process.
