Abstract

The utility model discloses a drilling jig for core parts of an excavator. The drilling jig comprises a round drilling jig plate which is provided with locating grooves used for locating the parts; the drilling jig plate is provided with drilling jig holes which are provided with fixing drilling sleeves inside; and the drilling jig plate is provided with a fixing bolt hole in the middle. Compared with a conventional driller, the drilling jig has the advantages of simple structure, convenience in machining, smart design, safety, reliability and rapidness in clamping and locating, and is capable of guaranteeing machining precision of drilling of the core parts and pressing plates and improving working efficiency.

Description

A kind of hole drilling die for excavating movement class part

Technical field

The utility model relates to a kind of hole drilling die, particularly a kind of hole drilling die for excavating movement class part.

Background technology

At present, core class part is the important component in the little swivel coupling on the high speed excavator, it matches with housing unit, the little swivel coupling that has jointly formed excavator, for excavator provides hydraulic power, in the first batch of throwing process processed of this part, owing to there is not special tooling that driller's order of part is carried out Assurance of Size, what cause this part is processed with certain difficulty at common driller, error can occur by the accessory size that processes on the common driller, the qualification rate of product is low, produces a large amount of waste products, cause damage to company, so prior art is still perfect not.

Summary of the invention

The purpose of this utility model is: provide a kind of simple in structure, practical, draw materials conveniently, the clamping location is quick, a kind of hole drilling die for excavating movement class part of the borehole accuracy that can guarantee part, to overcome the deficiencies in the prior art.

The utility model is constructed as follows: a kind of hole drilling die for excavating movement class part, comprise circular bushing plate, bushing plate be provided with can locating element locating slot, be provided with the drill jig hole at bushing plate, in the drill jig hole, be provided with fixedly drill bushing; Middle part at bushing plate is provided with fixed bolt hole.

Be provided with 6 drill jig holes at locating slot.

Owing to adopted technique scheme, before the processing, at first core is installed on the Drilling machines bench, the T-shaped bolt that penetrates in the middle of the part, then bushing plate is placed on the part, the cylindrical on the part is matched with locating slot on the bushing plate, the other end of T-shaped bolt penetrates fixed bolt hole, the nut of tightening behind the location on the T-shaped bolt just can be fixed on drill jig and part on the Drilling machines bench firmly, carries out the Drilling operation in 6 holes; Compared with prior art, the utility model not only has advantage simple in structure, easy to process, and designs the advantages such as ingenious, safe and reliable, that clamping is located quick, as to guarantee core class part and pressing plate Drilling operation precision, increase work efficiency.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Enforcement of the present utility model: a kind of hole drilling die for excavating movement class part, comprise circular bushing plate 1, bushing plate 1 be provided with can locating element locating slot 2, be provided with drill jig hole 3 at bushing plate 1, in drill jig hole 3, be provided with fixedly drill bushing 4; Be provided with fixed bolt hole 5 at the middle part of bushing plate 1.

Be provided with 6 drill jig holes 3 at locating slot 2.

Fixedly drill bushing 4 plays guiding cutter and wear-resisting effect in boring procedure.

Before the processing, at first core is installed on the Drilling machines bench, the T-shaped bolt that penetrates in the middle of the part, then bushing plate 1 is placed on the part, cylindrical on the part is matched with locating slot 2 on the bushing plate, the other end of T-shaped bolt penetrates fixed bolt hole 5, and the nut of tightening behind the location on the T-shaped bolt just can be fixed on bushing plate 1 and part on the Drilling machines bench firmly, then utilizes drilling machine to carry out the Drilling operation in 6 holes;

Coming into operation of this cover bushing plate saved the time of part processing greatly, improved the working (machining) efficiency of part, and the easier assurance of part processing precision, and more stable quality is reliable.
