Description
Technical field
the utility model relates to drilling well junk mill technical field, is a kind of junk mill device.
Background technology
junk mill is grinding trouble of lost tool in hole, repair the special tool of top of fish, be divided into flat-bottom grind shoes, concave bottom milling shoe, efficient milling shoes, can also according to the customized extraordinary junk mill of customer demand, but existing junk mill exist cooling bad, the degree of depth of 15 meters can only be bored, can not meet drilling well demand.
Summary of the invention
the utility model provides a kind of junk mill device, overcomes the deficiency of above-mentioned prior art, its can effectively solve existing junk mill exist cooling bad, the degree of depth of 15 meters can only be bored, can not meet the problem of drilling well demand.
the technical solution of the utility model is realized by following measures: a kind of junk mill device, comprises body and lower body; The lower end of upper body and the upper end of lower body are fixed together; The mounting groove communicated is provided with in the bottom of upper body He in lower body, the upper surface of upper body is fixedly connected with alloy-layer, the upper surface of alloy-layer is arranged at intervals with the chip area of at least two, in upper body, is respectively arranged with the intercommunicating pore that each chip area is connected with mounting groove.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentionedly on the upper surface of alloy-layer, be symmetrically arranged with three chip areas, the inner of three chip areas is connected, the intercommunicating pore that the connectivity part at the middle part and three chip areas that are respectively arranged with each chip area in upper body is connected with mounting groove.
above-mentioned alloy-layer is high outside and low outside inclined-plane.
above-mentionedly on lower body, be provided with internal thread or external screw thread.
above-mentionedly circumferentially be provided with at least one annular groove at the lower outside at lower body.
above-mentioned alloy-layer is pile-up welding hard alloy layer; Or/and the external diameter of upper body is greater than the external diameter of lower body, mounting groove is up-small and down-big taper mounting groove.
the utility model reasonable and compact in structure, easy to use, by upper body, lower body and alloy-layer with the use of, realize the object of grinding trouble of lost tool in hole, there is safe and reliable and feature that is good cooling results, the utility model can get into the degree of depth of 35 meters to 40 meters, facilitates operation, improves operating efficiency.
Accompanying drawing explanation
accompanying drawing 1 is that the master of the utility model most preferred embodiment looks half section structural representation.
accompanying drawing 2 is the plan structure schematic diagram of accompanying drawing 1.
coding in accompanying drawing is respectively: 1 is upper body, and 2 is lower body, and 3 is mounting groove, and 4 is alloy-layer, and 5 is chip area, and 6 is intercommunicating pore, and 7 is annular groove.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. determines according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1,2, this junk mill device comprises body 1 and lower body 2; The lower end of upper body 1 and the upper end of lower body 2 are fixed together; The mounting groove 3 communicated is provided with in the bottom of upper body 1 He in lower body 2, the upper surface of upper body 1 is fixedly connected with alloy-layer 4, the upper surface of alloy-layer 4 is arranged at intervals with the chip area 5 of at least two, in upper body 1, is respectively arranged with the intercommunicating pore 6 that each chip area 5 is connected with mounting groove 3.During use, by mounting groove 3, the utility model is fixedly mounted on drilling rod.By alloy-layer 4, chip area 5 and intercommunicating pore 6, make the utility model can get into the degree of depth of 35 meters to 40 meters, there is safe and reliable and feature that is good cooling results, facilitate operation, improve operating efficiency.
according to actual needs, above-mentioned junk mill device can be made further optimization and/or improvements:
as shown in accompanying drawing 1,2, the upper surface of alloy-layer 4 is symmetrically arranged with three chip areas 5, the inner of three chip areas 5 is connected, and is respectively arranged with the intercommunicating pore 6 that the middle part of each chip area 5 is connected with mounting groove 3 with the connectivity part of three chip areas 5 in upper body 1.Like this, make cooling effect better.
as shown in accompanying drawing 1,2, alloy-layer 4 is high outside and low outside inclined-plane.Like this, the effect better playing grinding is convenient to.
as shown in Figure 1, lower body 2 is provided with internal thread or external screw thread.Like this, installation and removal are convenient to.
as shown in Figure 1, at least one annular groove 7 is circumferentially provided with at the lower outside of lower body 2.Like this, annular groove 7 is convenient to install sealing ring, plays better sealing effectiveness.
as shown in accompanying drawing 1,2, alloy-layer 4 is pile-up welding hard alloy layer; Or/and the external diameter of upper body 1 is greater than the external diameter of lower body 2, mounting groove 3 is up-small and down-big taper mounting groove.Like this, the hardness of pile-up welding hard alloy layer is larger, and ground effect is better; The utility model is fixedly mounted on drilling rod by mounting groove 3.
