Abstract
The utility model discloses a hole drilling tool for a hole system in a crankshaft balance weight combination face. The hole drilling tool comprises a clamp and is characterized in that the clamp comprises a horizontal plate, a longitudinal front plate, a rear plate and a rear lateral plate, the horizontal plate, the longitudinal front plate, the rear plate and the rear lateral plate are connected, two or more spaced combination face positioning blocks are fixedly connected to the lower end face of the horizontal plate, at least one tool positioning sleeve is arranged in the horizontal plate, the tool positioning sleeve and the combination face positioning blocks are arranged in a stagger mode, an axial positioning stud is arranged on the front plate through threads, two or more axial positioning screws are arranged on the rear plate through nuts, an ejection block is connected to the front end of each positioning screw, the front ends of the ejection blocks are in point contact, and a radial positioning block is connected to the rear lateral plate. According to the hole drilling tool, machining can be completed on a general device, the production efficiency is high, the operating difficulty is lowered, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of Crankshaft Machining frock, the drilling tool especially for crankshaft counter balance in conjunction with face system.
Background technology
In Crankshaft Machining field, a lot of bent axles all need to install balance weight, the type of attachment of balance weight and bent axle is varied, the balance weight of a lot of bent axles is to be screwed after machining, this just requires to make corresponding screwed hole and locating hole on the balance weight faying face (crank throw upper surface) at bent axle, and there is certain required precision in hole system, conventional is the processing of line location at present, but its inefficiency and be not easy to reach very much required precision, as processed with numerical control device, due to the structure particularity of bent axle, it is also suitable loaded down with trivial details operating, production efficiency does not also improve how many, cause the waste of resource.
Utility model content
The purpose of this utility model is for prior art above shortcomings, and the drilling tool of a kind of crankshaft counter balance in conjunction with face system is provided, and it can complete processing on common apparatus, and not only production efficiency is high, and has reduced operation easier and production cost.
For achieving the above object, a kind of crankshaft counter balance of the present utility model is in conjunction with the drilling tool of face system, comprise clamp body, it is characterized in that clamp body comprises connected level board, longitudinal header board, rear plate and back side panel, level board lower surface is fixedly connected with the faying face locating piece at more than two interval, in level board, be provided with at least one the cutter positioning cover with faying face locating piece Heterogeneous Permutation, on header board, be provided with axial positioning stud by screw thread, on rear plate, be provided with two above axial dog screws by nut, front end at each dog screw is associated with jacking block, the front end of jacking block is some contact, on back side panel, be associated with radial location piece.
When use, be placed on balance weight faying face (crank throw upper surface) in connection with face locating piece, the jacking block of each dog screw front end is withstood to the shoulder of crank throw rear side, radial location piece on back side panel is close to axle journal horizontal direction extreme position, rotational positioning double-screw bolt makes it withstand the front end face of crank throw again, can be to tool locating, the position of cutter positioning cover is the position of boring; Use the utility model positions, and has reduced operation easier, and not only production efficiency is high, and can on common apparatus, complete processing, and production cost is low;
As further improvement of the utility model, described positioning stud is positioned on the axial center line of level board, and the dog screw on rear plate is symmetrically placed in the both sides of positioning stud; Be convenient to keep the balance of frock, convenient location;
In sum, the utility model can complete processing on common apparatus, and not only production efficiency is high, and has reduced operation easier and production cost.
Brief description of the drawings
Fig. 1 is the front view that the utility model embodiment uses state.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, this crankshaft counter balance is in conjunction with the drilling tool of face system, comprise by the level board 2 being connected, longitudinal header board 3, the clamp body 1 that rear plate 4 and back side panel 5 form, level board 2 lower surfaces are fixedly connected with the faying face locating piece 6 at three intervals, in level board 2, be provided with two cutter positioning covers 7 with faying face locating piece 6 Heterogeneous Permutations, on header board 3, be provided with axial positioning stud 8 by screw thread, positioning stud 8 is positioned on the axial center line of level board, on rear plate 4, be provided with two axial dog screws 10 by nut 9, two dog screws 10 are symmetrically placed in the both sides of positioning stud 8, be associated with jacking block 11 at the front end of each dog screw 10, the front end of jacking block 11 is some contact, on back side panel 5, be associated with radial location piece 12.
When use, three faying face locating pieces 6 are placed on crank throw 13 upper surfaces, the jacking block 11 of two dog screw 10 front ends is withstood to the shoulder of crank throw 13 rear sides, radial location piece 12 on back side panel 5 is close to axle journal 14 horizontal direction extreme positions, rotational positioning double-screw bolt 8 makes it withstand the front end face of crank throw 13 again, can be to tool locating, the position of cutter positioning cover 7 is the position of boring; Use the utility model positions, and has reduced operation easier, and not only production efficiency is high, and can on common apparatus, complete processing, and production cost is low.
