Description

A kind of processing unit (plant) for square forging decussation hole
Technical field
This utility model patent relates to belonging to machining frock field, particularly relates to a kind of processing unit (plant) for square forging decussation hole.
Background technology
My company processes some square forging, there is the hole of cross inside, some through holes in one direction of subdrilling during boring, then some through holes of other direction (cross) are reprocessed, when being drilled into intersection location, the most drilled position is empty, and now the feather key of drill bit does not has guide effect, not guiding directly to drill through causes outlet the biggest, and the serious workpiece that causes is scrapped.For avoiding inclined for hole drill, need tune processing second half to intersection location (i.e. to boring), although so ensure that product quality, but often bore a hole after reversing end for end and be required for centering again, add the labor intensity of operative employee, working (machining) efficiency is relatively low.
Summary of the invention
The purpose of this utility model is to overcome a kind of processing method for square forging decussation hole and device ensureing drilling quality and improving production efficiency of above-mentioned not enough offer of the prior art.
The technical solution of the utility model is achieved in that a kind of processing unit (plant) for square forging decussation hole, including drilling rod and cutter hub, described drilling rod and cutter hub are connected by cutter hub union joint, it is characterized in that: this processing unit (plant) also includes a guiding union joint, described guiding union joint is to be uniformly arranged four feather keys at the circumferencial direction of the female end outer round surface of described cutter hub union joint to be formed, and four feather keys are separately mounted in four guide key grooves.
The width of described guide key groove is 16mm, the degree of depth is 6.5mm, a length of 70mm.
Described cutter hub union joint is connected with cutter hub by the female thread of its front end, and is connected with drilling rod by the external screw thread of its rear end.
nullA kind of processing method of the processing unit (plant) for square forging decussation hole,This processing method is as follows: when processing the decussation hole of square forging,First with milling machine by six facing cuts of square forging to size,Go up face plate more accurately to be marked the position in hole,Then special guide rail platform is placed on the guide rail of deep hole drilling and boring machine,By scribing position by workpiece centering,Five hole drills of φ 51mm are led to by cutter hub and described cutter hub union joint successively that first load onto φ 51mm,Then replace with φ 64mm cutter hub and load onto the described hole guiding union joint processing φ 64mm,When getting into holes intersection location,The position of drilled in φ 51mm through hole is empty,During drill bit feeding forward,Feather key on drill bit is the most inoperative,The feather key now guided on union joint supports on the inner surface in machined hole,Play guide effect,Ensure that φ 64mm hole drill exports partially in the range of technological requirement after logical.
The good effect that the technical solution of the utility model produces is as follows: the present invention loads onto, on original cutter hub drill bit union joint (for coupling cutter hub and drilling rod), four feather keys being distributed uniformly and circumferentially, guiding union joint is arranged on after drill bit cutter hub and is connected with drilling rod, when getting into intersection location, it is bearing on the most drilled hole surface because guiding feather key on union joint, guide effect is fine, directly exports partially in the range of technological requirement after logical for hole drill.
When getting into holes intersection location, the position of drilled in φ 51mm through hole is empty, during drill bit feeding forward, feather key on drill bit is the most inoperative, the feather key now guided on union joint supports on the inner surface in machined hole, play guide effect, it is ensured that after φ 64mm hole drill is logical, outlet is partially in the range of technological requirement (technological requirement exports partially≤1.5mm).So reduce centering number of times during boring, improve working (machining) efficiency and also reduce the labor intensity of operative employee simultaneously.
When getting into holes intersection location, the position of drilled in φ 51mm through hole is empty, during drill bit feeding forward, feather key on drill bit is the most inoperative, the feather key now guided on union joint supports on the inner surface in machined hole, play guide effect, it is ensured that φ 64mm hole drill leads to metapore partially in the range of technological requirement (technological requirement hole partially≤1.5mm).So reduce centering number of times during boring, improve working (machining) efficiency and also reduce the labor intensity of operative employee simultaneously.

Detailed description of the invention
A kind of processing unit (plant) for square forging decussation hole, as shown in Fig. 1,2,3,4,5, connected by cutter hub union joint 3 including drilling rod 1 and cutter hub 2, described drilling rod and cutter hub, the female thread of cutter hub union joint front end is connected with cutter hub, and the external screw thread of back is to be connected with drilling rod.This processing unit (plant) also includes a guiding union joint 6, guide union joint on the basis of former cutter hub union joint, on female end outer round surface, process equally distributed four guide key grooves 4, the width of guide key groove is 16mm, the degree of depth is 6.5mm, a length of 70mm, and load onto in guide key groove by key block (key block-type number: F216A, its size: a length of 16mm, width are 10mm, thickness is 5mm) and the feather key 5 of key body composition, during use, key to be directed to installs as shown in Figure 3, and upper grinding machine is directed to key excircle dimension and is milled to the size in required processing hole.
nullThe processing method of above-mentioned processing unit (plant) is as follows: when processing the hole of 5 φ 51mm and 5 φ 64mm of square forging decussation,First milling machine is gone up by six facing cuts of square forging to size,Go up face plate more accurately to be marked the position in hole,Then special guide rail platform is placed on the guide rail of deep hole drilling and boring machine,By scribing position by workpiece centering,First load onto cutter hub union joint shown in the cutter hub of φ 51mm and Fig. 1 to be led to by five hole drills of φ 51mm successively,Then replace with φ 64mm cutter hub and load onto the hole guiding union joint processing φ 64mm of the present invention,When getting into holes intersection location,The position of drilled in φ 51mm through hole is empty,During drill bit feeding forward,Feather key on drill bit is the most inoperative,The feather key now guided on union joint supports on the inner surface in machined hole,Play guide effect,Ensure that φ 64mm hole drill exports partially in the range of technological requirement (technological requirement exports partially≤1.5mm) after logical.So reduce centering number of times during boring, improve working (machining) efficiency, also reduce the labor intensity of operative employee simultaneously.
