Abstract
The utility model provides a drilling clamp for a screw workpiece, the clamp body is provided with a guiding hole, the back part of the guiding hole is connected with a positioning threaded hole, the upper part of the connecting part of the guiding hole and the positioning threaded hole on the clamp body is provided with a drill sleeve hole, the inner wall is provided with a drill sleeve, the tail end of the positioning threaded hole is provided with a positioning pin hole perpendicular to the positioning threaded hole, the position of the clamp body corresponding to the positioning threaded hole is provided with an upper scrap discharging hole coaxial with the drill sleeve hole and perpendicular to the drill sleeve hole, the clamp body at the lower part of the positioning threaded hole is provided with a lower scrap discharging hole coaxial with the drill sleeve hole, and a positioning pin is disposed in the positioning pin hole. A screw thread screwing structure is adopted for the clamp and the workpiece, positioning and clamping are combined, positioning is made to be more accurate, machining precision is higher, drill bit deviation since the wok piece and the drill bit are not concentric is prevented, disadvantage of screw thread damage of the workpiece due to small force bearing is overcome; and working hours are saved; the drilling clamp is also advantaged by structure simplification, easy manufacture, and cost reduction.
Description
Technical field
The utility model belongs to machining frock field, especially relates to a kind of screw rod class Workpiece boring anchor clamps.
Background technology
In existing technology, often adopt major diameter of thread or full thread location in the workpiece end boring of screw rod class.The former has damage to the workpiece screw thread, because excesssive gap is located in the location, and workpiece and drill bit be decentraction often, at this moment the workpiece screw thread can guide the drill bit sideslip, causes drill bit to fracture simultaneously; The latter is because the workpiece machined surface is jagged, and burr is stuck in and makes in the screwed hole that back-out is difficult when screwing out anchor clamps.Other have exist the location not smart, compress technical problems such as shakiness, chip removal difficulty.
Summary of the invention
The problem that the utility model will solve provide a kind of simple in structure, easy to operate, location accurately, screw rod class Workpiece boring anchor clamps that production efficiency is high, be particularly suitable for the boring of screw rod class workpiece end.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of screw rod class Workpiece boring anchor clamps, and chuck body is provided with pilot hole, is connected with positioning spiro pit after the pilot hole; The drill bushing hole is equipped with on the chuck body top of pilot hole and positioning spiro pit junction; Its inwall is equipped with drill bushing, and the positioning threads bore end is provided with perpendicular dowel hole, be provided with on the chuck body position corresponding with positioning spiro pit with drill bushing hole coaxial line and perpendicular on chip-removal hole; The chuck body that is positioned at the positioning spiro pit below is provided with the following chip-removal hole coaxial with the drill bushing hole, and alignment pin is installed in the dowel hole.
Further, the effective length of said positioning spiro pit is the length of alignment pin left side threaded portion, equals the length of three pitch of workpiece to be processed.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; Anchor clamps and workpiece adopt the screw thread tightened-up structure, and the location compresses and is integrated, and makes the location more accurate; Machining accuracy is higher, has avoided because the drill bit deviation phenomenon that workpiece and drill bit decentraction cause; Workpiece location contact area increases greatly, has overcome because lifting surface area forces the impaired shortcoming of workpiece screw thread for a short time; When workpiece screwed out anchor clamps, the burr at machined surface place need not the jam through screwed hole, has saved man-hour; Simplify the structure simultaneously, be easy to make, reduced cost.And have simple in structure, easy to operate, processing cost is low, the production efficiency advantages of higher.
Description of drawings

Fig. 2 is that diagrammatic sketch is analysed and observe in the chip-removal hole position of the screw rod class Workpiece boring anchor clamps of the utility model
Among the figure: 1, chuck body; 2, alignment pin; 3, drill bushing; 4, pilot hole; 5, positioning spiro pit; 6, go up chip-removal hole; 7, workpiece; 8, dowel hole; 9, following chip-removal hole
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of screw rod class of the utility model Workpiece boring anchor clamps; Chuck body 1 is provided with pilot hole 4, is connected with positioning spiro pit 5 after the pilot hole 4, and pilot hole 4 is equipped with the drill bushing hole with chuck body 1 top of positioning spiro pit 5 junctions; Its inwall is equipped with drill bushing 3; Positioning spiro pit 5 ends are provided with perpendicular dowel hole 8, be provided with on the corresponding position of chuck body 1 and positioning spiro pit 5 with drill bushing hole coaxial line and perpendicular on chip-removal hole 6, the chuck body 1 that is positioned at positioning spiro pit 5 belows is provided with the following chip-removal hole 9 coaxial with the drill bushing hole; Dowel hole is equipped with alignment pin (2) for 8 li, and wherein pilot hole 4 is what be communicated with positioning spiro pit 5.
In order further to optimize the performance of the utility model; The effective length of said positioning spiro pit 5; Be the length that the length of alignment pin left side threaded portion equals three pitch of workpiece to be processed 7, can guarantee the accurate location of workpiece 7, can shorten the time of workpiece loading and unloading 7 again.
The course of work of this instance: workpiece 7 through on the pilot hole 4 precession chuck body 1 with positioning spiro pit 5 that workpiece 7 matches in, when workpiece 7 is screwed into alignment pin 2 places, promptly realized the location of workpiece 7
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
