Description
Technical field
The utility model relates to a kind of clamping tool, particularly relates to a kind of lathe clamping assembly.
Background technology
Stop valve such as core level lip weldering stop valve is threaded connection by valve body and valve gap to form, then reach external seal by the lip side weld seam of valve body and valve gap faying face.In the maintenance and maintenance process of stop valve, the lip side weld seam of valve body and valve gap needs cutting, and can disintegrate valve body valve gap.
At present, the lip side weld seam of valve body and valve gap adopts manually cutting (as saw blade) mostly, and efficiency is low, is difficult to mass disposal; And manual operation has uncertainty, easily cut partially, cause the faying face after grinding undesirable.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of by clamping for stop valve on lathe, realize the lathe clamping assembly that lathe cuts stop valve lip side weld seaming and cutting.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of lathe clamping assembly, comprise the clamping part on several claw for being welded on lathe chuck, clamping part described in each all has the first relative side and the second side, described first side forms the solder side being used for welding with described claw, and described second side forms clamping that is used for clamping stop valve.
Preferably, described clamping the arcwall face being corresponding described stop valve periphery and arranging.
Preferably, described arcwall face is smooth arcwall face.
Preferably, described clamping is convexly equipped with step along described clamping length direction.
Preferably, described step is positioned at described clamping upper side.
Preferably, described step is one-body molded on described clamping.
Preferably, described step is arcwall face away from the surface of described clamping.
Preferably, several described clamping part is separately around the ring that formation one is coaxial with described stop valve.
Preferably, this clamping assembly comprises three described clamping parts.
Preferably, this clamping assembly comprises four described clamping parts.
Lathe clamping assembly of the present utility model, comprise several clamping part be welded on the claw of lathe chuck, by the clamping stop valve of clamping part, with by stop valve clamping on lathe, be beneficial to the lip side weld seam of lathe to stop valve and carry out Cutting and Dismantling, comparatively in manual cutting of the prior art, efficiency is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of lathe clamping components welding on claw of the utility model one embodiment;
Fig. 2 is the structural representation of a clamping part of the lathe clamping assembly of the utility model one embodiment.
Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe detailed description of the invention of the present utility model in detail.
As shown in Figure 1-2, the lathe clamping assembly of the utility model one embodiment, comprises several clamping part 1, and clamping part 1, for being welded on the claw 21 of lathe chuck 2, being moved to chuck 2 central shaft by claw 21 and drives clamping part 1 to move.Each clamping part 1 all has the first relative side and the second side; First side forms the solder side 11 being used for welding with claw 21, and clamping part 1 is arranged on claw 21 by welding manner, stable connection; Second side forms the clamping face 12 being used for clamping stop valve, stop valve is placed on the centre position of several clamping part 1, being moved by claw 21 drives clamping part 1 clamping in stop valve periphery, thus stop valve is arranged on lathe, be beneficial to the lip side weld seam of lathe to stop valve and carry out Cutting and Dismantling, efficiency is high and uniformity good.
Particularly, several clamping part 1 is welded on claw 21 one end end face in opposite directions respectively by solder side 11, thus the clamping face 12 of several clamping part 1 is in opposite directions towards the central shaft of lathe chuck 2, with by clamping for the stop valve centre position at lathe chuck 2.
Described stop valve comprises core level lip weldering stop valve used in nuclear power station.Usually, stop valve periphery is all rounded, and therefore the clamping face 12 of clamping part 1 is arcwall face, with clamping in stop valve periphery in consistent manner.This arcwall face is smooth arcwall face, not cause wearing and tearing to stop valve periphery while clamping stop valve.Several clamping part 1 is separately around the ring that formation one and stop valve are coaxial; On this clamping part 1 radian in clamping face 12 main corresponding want the periphery of clamping stop valve to arrange.
Usually, it stop valve not the column structure of same diameter by clamping position, and there is step or the chamfering structure of different-diameter, therefore, further, clamping face 12 is convexly equipped with step 13 along clamping face 12 length direction, thus clamping face 12 and step 13 can be clamping on the different-diameter periphery of stop valve respectively.
In the present embodiment, this step 13 is positioned at side on clamping face 12; Clamping part 1 is welded on claw 21 inside lathe chuck 2 with step 13 on lathe chuck 2.The periphery of corresponding stop valve, this step 13 is also arcwall face away from the surface in clamping face 12.
Understandably, clamping face 12 top bar 13 setting be not limited to one, it also can be multiple, mainly arranges according to stop valve peripheral structure.
In addition, step 13 is one-body molded on clamping face 12, thus forms the clamping part 1 of good integrity.Clamping part 1 preferably adopts Steel material to make, and hardness is high, durable.
The clamping mainly clamping seam of the lip side weld at the stop valve side of above-mentioned middle clamping part 1 pair of stop valve.After clamping, lathe operates, and cut by the lip side weld seam of lathe tool to stop valve, valve body and valve gap to be disintegrated, efficiency is high.
As shown in Figure 1, in the present embodiment, clamping assembly comprises three clamping parts 1, is welded on respectively on three claws 21 of lathe chuck 2.Certainly, according to the number change of lathe chuck 2 claw 21, the quantity of clamping part 1 also can respective change, and as chuck, this clamping assembly then comprises four clamping parts 1, is welded on respectively on four claws.The entire length of clamping part 1 also can be arranged according to stop valve outer circumference diameter.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
