Description
Technical field
The utility model belongs to machining equipment technical field, is specifically related to a kind of vertical car turning head stabilising arrangement.
Background technology
As illustrated in the accompanying drawings from 1 to 3, the top of turning head 1 is with locating shaft 2, be provided with 3 T-shaped fixing holes 3 in the bottom of knife rest top board simultaneously, when turning head 1 is fixed with ram 4, locating hole 5,3 hold-down screws 6 that locating shaft 2 is positioned at ram are each passed through fixing hole 3 to carry out handle by turning head 1 and ram 4 and closes.As shown in Figure 3, when lathe tool is subject to lasting large Cutting Force as indicated by the arrow or under the mal-conditions such as interrupted cut, hold-down screw often loosens, diameter due to hold-down screw is slightly less than the diameter of fixing hole, after hold-down screw generation loosens, turning head can produce around locating shaft and rotate, although this rotation amplitude is little, be enough to the machining accuracy having influence on product.
Summary of the invention
For overcoming the technical problem that vertical car turning head at present rotates when being subject to lasting large Cutting Force, the utility model provides a kind of vertical car turning head stabilising arrangement.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: vertical car turning head stabilising arrangement, it comprises ram and the knife rest fixing with ram, the top of described knife rest is provided with locating shaft, the bottom of knife rest top board is provided with T-shaped fixing hole, locating shaft is positioned at the locating hole of ram, ram is combined fixing by hold-down screw with knife rest through fixing hole, it is characterized in that: the bottom surface of described ram is fixed an alignment pin, the knife rest end face corresponding with alignment pin is provided with slot, and alignment pin is positioned at slot.
This vertical car turning head stabilising arrangement by increasing alignment pin between ram and knife rest, ensure that knife rest is in cutting force when continuing the mal-conditions such as larger or interrupted cut, between cutter holder and ram, hold-down screw loosens, cutter holder is in stable state, thus ensures the machining accuracy of workpiece and extend the service life of knife rest.

In figure, 1, knife rest, 2, locating shaft, 3, fixing hole, 4, ram, 5, locating hole, 6, hold-down screw, 7, alignment pin, 8, slot.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in figs. 4 through 6, vertical car turning head stabilising arrangement, it comprises ram 4 and the knife rest 1 fixing with ram, the top of described knife rest is provided with locating shaft 2, the bottom of knife rest top board is provided with T-shaped fixing hole 3, locating shaft 2 is positioned at the locating hole 5 of ram, and ram 4 and knife rest 1 handle close through fixing hole 3 by hold-down screw 6, and said structure is identical with structure of the prior art.
As shown in Figure 4, this stabilising arrangement comprises in the improvement of original structure, and the bottom surface of ram 4 is fixed an alignment pin 7, by reference to the accompanying drawings 5 and accompanying drawing 6 shown in, the knife rest end face corresponding with alignment pin 7 is provided with slot 8, and alignment pin 7 is positioned at slot 7.
By increase alignment pin 7 between ram 4 and knife rest 1 after, knife rest is when lasting large Cutting Force or interrupted cut, the stability combined between knife rest 1 and ram 4 greatly improves, can prevent hold-down screw 6 generation from loosening causes knife rest around the appearance of locating shaft rotation phenomenon, guarantee the machining accuracy of product, simultaneously also can service life of extension carriage.
