Abstract
The utility model provides a deep hole drill point utensil for small -size orthopedics hollow screw, includes three -jaw (holding) chuck, correct grinding extension bar, drill chuck, orthopedics hollow screw, drill gun, hydraulic pressure three -jaw locating rack, oil extraction row cotter way, drill bit uide bushing, machine tool tailstock, correct grinding extension bar one end is installed on lathe three -jaw chuck, the other end at the correct grinding extension bar is installed to the drill chuck, orthopedics hollow screw install on the drill chuck, hydraulic pressure three -jaw locating rack is installed at orthopedics hollow screw middle part, and is rotatory each other with orthopedics hollow screw, the drill gun afterbody is installed on machine tool tailstock, and the drill gun drill bit is installed in the drill bit uide bushing, the oil extraction is arranged the cotter way and is installed between orthopedics hollow screw and drill gun drill bit. Adoption correct grinding extension bar dress card, hydraulic pressure three -jaw locating rack is to hollow screw's location, processing positioning accuracy height, the drill chuck adopts the fixed principle of three -jaw, can be suitable for the work piece in many emptying apertures footpath, the drill chuck from the center that work piece and main shaft can be guaranteed in the centring on same axis, can not result in a stomidium incline.
Description
Technical field
This utility model relates to the technical field of orthopaedic medical treatment Product processing, specifically a kind of depth drill fixture for small-sized orthopaedics hollow screw.
Background technology
At present, when the little hollow screw of processing orthopaedic medical treatment product, deep hole drilling machine is when converted products because some product length is shorter, and after lathe, positioning seat exceeds stroke range, cannot contact with centralized positioning seat, cause that this series products cannot be processed.Generally making extension bar in prior art makes rear tailstock strengthen with centralized positioning seat distance, convenient location, thus reaching processing purpose.But this scheme is when processing the raw material of different-diameter, and in frock, hole can not regulate, and making multiple frock wastes time and energy；Because product and frock jackscrew are fixed, the stomidium deviation material center adding man-hour away from centralized positioning frame can be caused.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of depth drill fixture for small-sized orthopaedics hollow screw.
This utility model is adopted the technical scheme that by the technical problem solving to exist in known technology:
Depth drill fixture for small-sized orthopaedics hollow screw of the present utility model, including three-jaw chuck, fine grinding extension bar, drill chuck, orthopaedics hollow screw, drill gun, hydraulic pressure three-jaw locating rack, oil extraction row cotter way, drill bit fairlead, tailstock tool；Fine grinding extension bar one end is arranged on machine tool three-jaw chuck；Drill chuck is arranged on the other end of fine grinding extension bar；Orthopaedics hollow screw is arranged on drill chuck；Hydraulic pressure three-jaw locating rack is arranged in the middle part of orthopaedics hollow screw, mutually rotates with orthopaedics hollow screw, it is achieved location and the support to orthopaedics hollow screw；Drill gun afterbody is arranged on tailstock tool, and gun drill is arranged in drill bit fairlead；Oil extraction row's cotter way is arranged between orthopaedics hollow screw and gun drill.
This utility model has the advantage that and has the benefit effect that
In depth drill fixture for small-sized orthopaedics hollow screw of the present utility model, adopting fine grinding extension bar to be installed, the hydraulic pressure three-jaw locating rack location to hollow screw, setting accuracy on work is high；Drill chuck adopts the principle that three-jaw is fixing, it is possible to be suitable for the workpiece in many emptying apertures footpath；The self centering of drill chuck can ensure that the center of workpiece and main shaft is on the same axis, is not result in a stomidium deflection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the depth drill fixture for small-sized orthopaedics hollow screw of the present utility model.
Detailed description of the invention
Below by way of the drawings and specific embodiments, the technical solution of the utility model is described in detail.
As it is shown in figure 1, the depth drill fixture for small-sized orthopaedics hollow screw of the present utility model includes three-jaw chuck 1, fine grinding extension bar 2, drill chuck 3, orthopaedics hollow screw 4, drill gun 5, hydraulic pressure three-jaw locating rack 6, oil extraction row cotter way 7, drill bit fairlead 8, tailstock tool 9.Described fine grinding extension bar 2 one end is arranged on machine tool three-jaw chuck 1；Described drill chuck 3 is arranged on the other end of fine grinding extension bar 2；Described orthopaedics hollow screw 4 is arranged on drill chuck 3；Described hydraulic pressure three-jaw locating rack 6 is arranged in the middle part of orthopaedics hollow screw 4, mutually can rotate with hollow screw 4, it is achieved location and the support to hollow screw 4；Described drill gun 5 afterbody is arranged on lathe 9 tailstock, and drill gun 5 drill bit is arranged in drill bit fairlead 8, it is achieved the guide effect to drill bit；Described oil extraction row's cotter way 7 is arranged between orthopaedics hollow screw 4 and drill gun 5 drill bit, it is achieved chip removal.
The above, it it is only preferred embodiment of the present utility model, not this utility model is done any pro forma restriction, although this utility model is with preferred embodiment openly as above, but, it is not limited to this utility model, any those skilled in the art, without departing within the scope of technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solutions of the utility model, any simple modification above example made according to technical spirit of the present utility model, equivalent variations and modification, belong in the scope of technical solutions of the utility model.
