Description
Technical field:
The utility model relates to a kind of crawler belt bolt hole inner plane ream machine, is used for the processing of track link rail bolt hole inner plane.
Background technology:
Chain rail joint bolt hole inner plane is the faying face of bolted, nut by with the connecting of bolt, with creeper tread and the chain rail assembly formation crawler belt that tightens together.The height of chain rail joint bolt hole inner plane precision directly has influence on the fastening degree of creeper tread, thereby has influence on the service life of crawler belt, so must guarantee its machining accuracy.But because the chain rail joint bolt hole inner plane that needs processing adopts common counterbit to process in the inboard of chain rail joint.This nut face of ream was to adopt drilling machine in the past, and drilling rod is goed deep in the bolt hole, interchangeable little cutter hub is fastened on carries out the ream face on the drilling rod then, and the face injustice that not only low, the troublesome poeration of efficient, and ream goes out, the degree of depth differs, and precision does not reach designing requirement yet.
Summary of the invention:
The purpose of this utility model provides a kind of crawler belt bolt hole inner plane ream machine, and a clamping workpiece just can be finished the processing of chain rail joint upper bolt hole inner plane automatically.
The purpose of this utility model realizes as follows: this crawler belt bolt hole inner plane ream machine, relate to base, column, slide unit, main spindle box, positioning and clamping mechanism and cutting tool assembly, column is fixed on the base rear side, fixing slide unit on the column, the main spindle box device is on slide unit, cutting tool assembly is connected on the headstock spindle, positioning and clamping mechanism is fixed on the base and below cutting tool assembly, it more than is the structure of many universal machine tools, they constitute the body of whole lathe, the location of finishing workpiece clamps, the feeding of cutter and spinning movement, the clamping of workpiece can be adopted the small-sized hydraulic oil cylinder, and the main feature of this lathe is in the cutting tool assembly part.Cutting tool assembly is by big cutter hub, little cutter hub, holddown spring, locking pin, slide block, positioning sleeve, attachment pegs and cutter head are formed, main shaft on big cutter hub and the main spindle box connects, be inserted in the positioning sleeve endoporus bottom of big cutter hub, be with holddown spring on the big cutter hub, its two ends are pressed between big cutter hub and the positioning sleeve upper end, the slide block that is embedded in the big cutter hub groove is fixed with locking pin, slide block is wider than the two ends of big cutter hub in the chute of positioning sleeve both sides, and with positioning sleeve be matched in clearance, pocket knife body and function attachment pegs is connected with the hole of positioning sleeve, form pocket knife body swing fulcrum, on the big cutter hub skewed slot is arranged, the plush copper of pocket knife body upper end is inserted in the skewed slot, and cutter head is fixed on the lower end of little cutter hub; Connect gripper shoe with base, support set is arranged on the gripper shoe, bearing is equipped with in support set endoporus bottom, and little cutter hub stretched out from the support set endoporus when positioning sleeve fell, and the bottom convex shoulder of positioning sleeve is pressed on support set inner bearing top.
According to the characteristics of processing work, main shaft is 4 covers with cutting tool assembly on being connected it, once can finish the processing of four bolt hole inner planes of two chain rails joints.
During the work of this machine, chain rail joint is placed on the positioning and clamping mechanism, starts hydra-electric system, clamping cylinder clamps workpiece, the cutter rotation, hydraulic pressure moving platform F.F. cutter during near workpiece the worker advance.When rotating under the drive of big cutter hub at main spindle box and moving downward, positioning sleeve enters in the support set, the bolt hole that the cutter head of little cutter hub passes on the workpiece is in the bolt hole bottom surface, and then the positioning sleeve lower end is pressed on the interior bearing of support set, the following shifting movement of support set restriction positioning sleeve, the slide block that is embedded on the big cutter hub moves downward relatively along the chute of positioning sleeve, the plush copper of pocket knife body upper end is moved along the skewed slot on the big cutter hub, thereby little cutter hub is swung around attachment pegs, and under the drive of positioning sleeve, rotate, the blade on the little cutter hub will carry out radial and axial cutting.When big cutter hub moved to lower dead center, little cutter hub only carried out radial cutting, thereby the processing plane ream is flat.When lathe up stroke or position-sensing switch sent signal, big cutter hub retreated, under the effect of compression spring, positioning sleeve produces with big cutter hub and relatively moves, simultaneously the plush copper of little cutter hub moves down along skewed slot, little cutter hub around attachment pegs to lower swing, when slide block rises to the upper end of chute, little cutter hub swings to the upright position just, with moving on the big cutter hub and be raised to original position, whole process is finished, and unclamps clamping cylinder then, workpiece is taken off, can carry out the processing of next workpiece.
The advantage of this crawler belt bolt hole inner plane ream machine: utilize this machine to solve the unmanageable difficult problem of track link rail nut face, make the simple of operation change, production efficiency has improved more than 2 times, and can guarantee machining accuracy, makes constant product quality.Utilize its cutting tool assembly can finish other casings in addition more complex part adopt common counterbit to process or, also can adopt a plurality of cutting tool assemblies that a plurality of planes are processed simultaneously simultaneously with the relatively plane processing of difficulty of boring bar processing.
Description of drawings:
Accompanying drawing is the structural representation of the utility model crawler belt bolt hole inner plane ream machine.
