Abstract
The utility model discloses a disassembling device of a conical drill bit for probing. The disassembling device is composed of a cup-shaped main body and an end cover in threaded connection with the cup-shaped main body, wherein the cup-shaped main body is provided with a cavity with the shape thereof matching with that of a spiral cone of the conical spiral drill bit; the cavity is at least provided with a bump in concave-convex combination with partial spiral groove of the spiral cone; a hexahedron is arranged at the center of the surface of the end cover; and the center of the hexahedron is provided with a via hole with the diameter greater than that of a drilling handle. The cup-shaped main body of the disassembling device has an outer shape including the hexahedron which is firmly and conveniently clamped by a clamping tool such as a bench clamp; and the cup-shaped main body and the end cover can fix the spiral cone of the conical spiral drill bit in the cup-shaped main body, so that the spiral cone is firmly clamped indirectly by firmly clamping the cup-shaped main body. The drilling handle can be disassembled successfully by using tools such as a wrench to pass through a clamping groove which is symmetrical with the drilling handle after the cup-shaped main body is fixed, so that the technical problem that the spiral cone is easy to damage due to direct clamping is avoided thoroughly. The disassembling device of the conical drill bit for probing, disclosed by the utility model, has the outstanding advantages of a simple and rational structure and convenience for use.
Description
Technical field
The utility model belongs to specific purpose tool, particularly relates to the disassembling apparatus that a kind of feeler inspection is used tapered twist drill.
Background technology
Feeler inspection forms by screw cone with the drillstock of dead-pipe type center water channel with tapered twist drill, and screw cone is threaded with drillstock.Screw cone is to need often maintenance so that the consumable accessory of changing, yet the feeler inspection operation will make screw cone tightr with being connected of drillstock, therefore it is very difficult to utilize the general purpose tools such as bench vice, spanner that screw cone and drillstock are disassembled before the maintenance, disassembles screw cone improper even that damage should be keeped in repair.
Summary of the invention
The utility model is in order to solve general purpose tools such as utilizing bench vice, spanner screw cone and drillstock to be disassembled very difficult technical problem, and proposes the disassembling apparatus that a kind of feeler inspection is used tapered twist drill.
The utility model is taked following technical scheme for achieving the above object: this disassembling apparatus is comprised of cup shaped body and the end cap that is threadedly connected to cup shaped body rim of a cup side, described cup shaped body is provided with the die cavity that coincide with the screw cone shape of tapered twist drill, described die cavity is provided with and the concavo-convex projection that engages of the part helicla flute of screw cone at least, described end cover surface center is provided with hexahedron, and hexahedral center is provided with the via hole greater than the drillstock diameter.
The utility model can also be taked following technical scheme:
Described cup shaped body is provided with hexahedron with respect to the cup bottom side of rim of a cup side.
The inboard of described end cap is provided with the annular boss that engages with the screw cone top.
The described cup shaped body that is threaded is opposite with the hand of spiral that drillstock and screw cone are threaded with its hand of spiral of end cap.
The beneficial effects of the utility model and advantage are: the cup shaped body of this disassembling apparatus has the hexahedral outer shape that comprises of being convenient to the clamping device firm grip such as bench vice, and cup shaped body and end cap can be fixing wherein with the screw cone of tapered twist drill, thus the firm grip cup shaped body just indirectly firm grip screw cone.Fixedly after the cup shaped body, use the instrument such as spanner can successfully drillstock to be disassembled by the draw-in groove of drillstock symmetry, thoroughly avoided direct clamping screw spiral cone easily with the technical barrier of its damage.The utlity model has outstanding advantages simple and reasonable, easy to use.
Description of drawings
Accompanying drawing 2 is Fig. 1 generalized sections.
Accompanying drawing 3 is that Fig. 1 embodiment uses the state generalized section.
Number in the figure: 1 cup shaped body, 1-1 main body hexahedron, 1-2 projection, 2 end caps, 2-1 end cap hexahedron, 2-2 via hole, 2-3 annular boss, 3 screw cones, 4 drip rings, 5 drillstocks, 5-1 draw-in groove.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
With reference to Fig. 1,2,3 embodiment 1, this disassembling apparatus is comprised of cup shaped body 1 and the end cap 2 that is threadedly connected to cup shaped body rim of a cup side.
Cup shaped body 1 is provided with the die cavity that coincide with screw cone 3 shapes of tapered twist drill, and this die cavity is provided with and the concavo-convex protruding 1-2 that engages of the part helicla flute of screw cone 3 at least.
The protruding 1-2 of die cavity is that screw cone 3 can not be rotated in the die cavity of cup shaped body with the concavo-convex purpose that engages of the part helicla flute of screw cone 3, and another purpose is convenient the manufacturing.
Among the figure, end cap 2 centre of surfaces are provided with end cap hexahedron 2-1, and the hexahedral center of end cap is provided with the via hole 2-2 greater than drillstock 5 diameters of tapered twist drill.The effect of end cap hexahedron 2-1 is in order to use the fastening end cap 2 of spanner in cup shaped body 1.The inboard of end cap 2 is provided with the annular boss 2-3 that engages with screw cone 3 tops, and annular boss 2-3 is beneficial to the fixing of screw cone 3.
Among the figure, 1 glass of bottom side of cup shaped body is provided with main body hexahedron 1-1, and the effect of main body hexahedron 1-1 is for the ease of clamping device firm grip cup shaped body 1 such as bench vices.
The cup shaped body 1 that the utility model is threaded is opposite with the hand of spiral that drillstock 5 and screw cone 3 are threaded with end cap 2 its hand of spirals, make drillstock 5 in the process of disassembling to be subjected to force direction and end cap 2 to screw direction consistent, can avoid end cap to get loose.
Among Fig. 3, the tapered twist drill that is made of screw cone 3, drillstock 5 also has 4 drip rings 4, uses this disassembling apparatus also to help the drip ring 4 of changing or repairing.
