Abstract

The invention discloses an adjustable drilling jig for a shaft. The adjustable drilling jig comprises a bottom plate (6) and V-shaped blocks (5), wherein a plurality of parallel T-shaped grooves are formed in the bottom plate (6), and the V-shaped blocks (5) are connected with the T-shaped grooves through positioning keys respectively. Adjusting cushion blocks (4) are fixed to the two side faces of a V-shaped groove of each V-shaped block through screws respectively. The portion, between every two adjacent T-shaped grooves, of the bottom plate (6) is provided with a bolt hole, a bolt and a nut. The bolts penetrate through a pressing plate (2). In addition, positioning pieces (3) are arranged at the same side ends of the T-shaped grooves in the bottom plate (6). The adjustable drilling jig for the shaft has the advantages of being convenient to adjust, simple in workpiece feeding operation and workpiece discharging opening, good in universality, high in positioning accuracy and production efficiency and the like.

Description

Adjustable axle boring grab
Technical field
The present invention relates to a kind of Machining of Shaft-type Parts fixture, more particularly, relate to shaft parts drill hole fixture.
Background technology
Thrust wheel, guide wheel are indispensable parts in the crawler type walking mechanisms such as bull-dozer, excavator.They or carrying fuselage weight, or the operation of guiding chain crawler belt, so vital effect is played in the normal work to crawler type walking mechanism.Due to crawler type walking mechanism, be widely used in the middle of engineering machinery, be used for greatly working in the operating mode rugged environments such as ore extraction, building excavation.In order to guarantee the service life of thrust wheel, guide wheel, the processing of itself has strictly and the requirement of system.
At thrust wheel, guide wheel " three-major-items "---body, axle, lid.As shown in Figure 1, in Machining of Shaft-type Parts, the most vital part is exactly the processing of two pin-and-holes on axle.The distance of two pin-and-holes on axle, determined completely between wheel body and lid can play distance.Between wheel body and lid can play distance not only affect wheel body running clearance, the effective intensity of friction (friction is necessary friction, but frictional strength is excessive, accelerates frictional dissipation, shorten wheel body service life), guarantees the key of the normal operation of wheel body especially.Can play distance excessive, be difficult to guarantee wheel sealing effectiveness, easily there is oil leakage phenomenon.Can play distance too small, easily there is locking phenomenon after heating up and expanding in wheel motion, cannot normal rotation.
Pin-and-hole processing technology on traditional axle, is location single-piece axis body, coordinates drill jig, on radial drill, processes.Specifically as shown in Figure 2, procedure of processing is.
1, first axle is steadily put on vee-block, is close to top bolt, must be close to and put in place and axle is close on vee-block.
2, tighten pressing plate top nut, pressing plate is abutted against on axial plane, start processing.Original structure is as shown in the figure:
Above-mentioned processing mode, drill jig complex operation, the making of drill jig itself is also very loaded down with trivial details, and a kind of axial workpiece of every processing, will measure body for it and design and produce the defects such as a set of drill jig.These defects, affect the machining accuracy of axial workpiece and the main cause of working (machining) efficiency beyond doubt.
Summary of the invention
The present invention aim to provide a kind of easy to adjust, lifting workpiece is simple to operate, versatility good, the adjustable axle boring grab that positioning precision and production efficiency are high.
In order to achieve the above object, the invention provides a kind of adjustable axle boring grab, comprise the base plate that offers a plurality of parallel T-shaped grooves, and the vee-block that connects separately respectively each T-shaped groove by positioning key, the V-shaped groove two sides of described vee-block are fixed with adjustment cushion block by screw respectively.In addition, in described base plate, between adjacent two described T-shaped grooves, be provided with bolt hole, and be provided with bolt, nut; Described bolt has also worn pressing plate; In addition, on described base plate, the same side of each T-shaped groove is provided with keeper.
Under a kind of optimal way, T-shaped Cao Wei six roads on above-mentioned base plate.
Beneficial effect of the present invention is.
1, simple, convenient, under similarity condition, more simple and convenient than the use of traditional drill jig.
2, easy to loading and unloading, increase work efficiency.
3, save material, cost, for the drill jig of prior art, process different axles, need different drill jigs, greatly consume material and manufacturing expense; And only need to adjust the spacing between vee-block and change the pad on vee-block for drill jig of the present invention.
In a word, that the present invention has is easy to adjust, lifting workpiece is simple to operate, versatility good, positioning precision and production efficiency high.

The specific embodiment
Fixture of the present invention can be processed six roots of sensation axial workpiece at most simultaneously, and axial workpiece that can indifference processing multiple types.Concrete structure as shown in Figure 3 and Figure 6, comprises the base plate 6 that offers a plurality of parallel T-shaped grooves, and the vee-block 5 that connects separately respectively each T-shaped groove by positioning key, and the V-shaped groove two sides of vee-block are fixed with and are adjusted cushion block 4 by screw respectively.In figure, between adjacent two the T-shaped grooves of base plate 6, be provided with bolt hole, and be provided with bolt, nut; Bolt has also worn pressing plate 2; In addition, on base plate 6, the same side of each T-shaped groove is provided with keeper 3.Visible in figure, T-shaped Cao Wei six roads, simultaneously by clamping six roots of sensation axial workpiece 1 to be processed.
In addition, as shown in Figure 4, positioning key comprises locating piece 7 parts and screw thread locating piece 8 parts that are threaded connection under rectangle.
The present invention can be the axial workpiece that coordinates all lengths different model, be designed to positioning V-shaped interblock apart from adjustable, specifically as shown in Figure 5, different according to the length that will process model axial workpiece, can adjust at any time, under specific (special) requirements, even can process the axial workpiece of different length simultaneously.Specifically, run into the axial workpiece of different length scope, without adjusting vee-block, only need adjust keeper according to part length front and back, in Fig. 5, the structure that M, N are different spacing.
In addition,, when running into the axial workpiece of different-diameter scope, without changing vee-block, only need to change supporting adjustment cushion block 4 on V piece.
It is very convenient that this drill jig is installed, applicable and various types of Digit Control Machine Tools, drill jig when working shaft-like part, locate very convenient, once adjust fixing after, without carrying out again the adjustment of indivedual location.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
