Abstract

The utility model discloses a tool used for processing lug holes of universal joint forks, comprising a base with a mounting hole, an upright board which is vertically arranged on the base, a guide bar which is horizontally and slidingly arranged on the upright board and a front push plate and a back push plate which are arranged at two ends of the guide bar. A positioning disk is detachably arranged at the front side of the upright board and a power mechanism which is in transmission connection with the back push plate is arranged at the back side of the upright board. A pushing mechanism which relatively fits with the positioning disk is arranged at the front push plate. The tool disclosed by the utility model has a reasonable design and a simple structure; after being installed at numerical control milling machines, the tool can accelerate cutter movement in stroke of no processing of the cutter by adopting a variable-speed motor and save time by adopting the tool with dual working stations to get rid of non-cutting time. As machining cuttings are adopted as numerical control milling cutters, cutters are changed at regular intervals instead of being sharpened. As a high-pressure cylinder is adopted as the power mechanism to clamp, the labor intensity of workers is lowered. As two cutters are arranged at one cutter bar and semi-fine-boring and fine boring are finished at the same time at one feeding, the processing time is greatly saved.

Description

Processing universal-joint fork earhole is used frock

Technical field

The utility model relates to a kind of frock that is used for machine-building, is specifically related to process the universal-joint fork earhole and uses frock.

Background technology

Traditional method is to adopt the Buddha's warrior attendant boring to process in processing universal-joint fork earhole operation; In the process of processing earhole, utilize two ear black skins to push down the end face location simultaneously; Promptly two ears are located with V-block down; Manually tighten the end face that cylinder withstands the universal-joint fork part with one simultaneously, two unit heads are equipped with two boring cutters and carry out half right boring and right boring respectively about the Buddha's warrior attendant boring, adopt above-mentioned processing technology to have following shortcoming or deficiency: ⑴, Buddha's warrior attendant boring in process; Adopt the right and left respectively to carry out half right boring and right boring, cutter needs twice feeding processing; ⑵ brazed shank tool is adopted in, Buddha's warrior attendant boring, and higher to workman's competency profiling, the skill that when will whet a knife and whet a knife needs the long time integration experience; ⑶, former Buddha's warrior attendant boring processing, the experienced operator processes 120 a working day, and production efficiency is low; ⑷ the employed frock of, Buddha's warrior attendant boring adopts manually tightens, and labour intensity is big, and ⑸, Buddha's warrior attendant boring cutter rotating speed are immutable, behind earhole of processing, to another earhole near the time speed non-adjustable, lose time.

The utility model content

The utility model provides a kind of processing universal-joint fork earhole that can reduce labor strength, enhance productivity to use frock in order to solve weak point of the prior art.

For solving the problems of the technologies described above; The utility model adopts following technical scheme: processing universal-joint fork earhole is used frock; Comprise preceding push pedal and back push pedal that the riser, the horizontal slip that vertically are provided with on base with installing hole, the base are located at the guide post on the riser and are located at the guide post two ends; The riser front side detachably is provided with positioning disk, and the riser rear side is provided with the actuating unit that is in transmission connection with the back push pedal, and preceding push pedal is provided with the jacking mechanism with the positioning disk relative engagement.

Said jacking mechanism comprises the adjusting screw mandrel that is threaded with preceding push pedal, the rear end that is located at adjustable plate and V-type locating piece on the guide post, regulates screw mandrel of sliding penetrate backward before push pedal be connected with the leading flank of adjustable plate; Adjustable plate trailing flank and V-type locating piece removably connect, and regulate the central lines of screw mandrel, V-type locating piece and positioning disk.

Be provided with lining between said guide post excircle and the riser.

Said actuating unit is a high-pressure cylinder.

Adopt technique scheme, two ears of universal-joint fork are contacted with positioning disk with jacking mechanism respectively with the nose circle face of having processed, wherein the center line of two earholes is vertical state; Operational power mechanism promotes the back push pedal backward, and back push pedal drives jacking mechanism through guide post universal-joint fork is compressed, and arranges two boring cutters at the boring cutter bar of CNC milling machine at the vertical direction correct position according to the size of earhole; Next boring cutter carries out half right boring processing; A last boring cutter carries out right boring processing, and the utility model is installed on the CNC milling machine, has shortened process time greatly; Save the labour, improved working (machining) efficiency.

The adjusting screw mandrel of jacking mechanism can be finely tuned the distance between V-type locating piece and the positioning disk, can process the universal-joint fork or the flange york of different model, makes function more various.The central lines of regulating screw mandrel, V-type locating piece and positioning disk can be guaranteed the installation accuracy of workpiece.Guide post can slide before and after the lining, after liner wear, can be easily resleeve more.

The utility model is reasonable in design, simple in structure, is installed on the CNC milling machine, adopts variable speed electric motors, particularly, does not have in cutter the stroke of processing, can accelerate tool motion, and adopts the double frock, does not have non-cutting time, has fully practiced thrift the time; The CNC milling cutter tool adopts machine tool, need not to whet a knife, and periodic replacement gets final product; Adopt high-pressure cylinder to clamp, reduced labor strength as actuating unit; Adopt one two cuttves to be set to knife bar, primary feed is accomplished half right boring and right boring simultaneously, has practiced thrift process time greatly.Through test, common laborer's every workday is processed 500 in universal-joint fork earhole, is to adopt three times of Buddha's warrior attendant boring originally, has improved production efficiency greatly; This is practical under the prerequisite that does not increase equipment and human input, has improved working (machining) efficiency greatly, has reduced labor strength, has practiced thrift cost.
