Abstract
The utility model relates to an ejector pin indexing mechanism, which is mainly composed of an ejector pin rack bar, a small shaft, an indexing disk, a swing rod, a top pin, a slide block rack bar, a detent, a ratchet wheel, a detent shaft, a spring, a gear and a center shaft. The utility model is characterized in that the center shaft is sheathed with the detent shaft, the ratchet wheel, the indexing disk, etc., an opening groove is arranged on the indexing disk, and the ratchet wheel is engaged with the slide block rack bar; the small shaft is sheathed with the gear, the swing rod and the top pin which is inserted in the opening groove of the indexing disk, the gear is engaged with the ejector pin rack bar which is parallel to the slide block rack bar, and the other end of the ejector pin rack bar is provided with the spring. The utility model has the advantages of simple structure, easy indexing and high precision.
Description
The push rod indexing mechanism is a kind of mach servicing unit, is mainly used in the transposition cutterhead, belongs to operation, transportation class.
Indexing mechanism is a kind of common machining set-up, utilizes indexing mechanism, and the position that cutter, workpiece etc. can be put needs processes.Especially in the Gear Processing process, because the wearing and tearing of cutter, processing a gear often needs to change knives, because the tooth of gear is on the move, therefore must use indexing mechanism simultaneously.And existing indexing mechanism mostly is manual calibration greatly, and time-consuming, effort, work efficiency are low.If it is use the power calibration, then very complicated.
The purpose of this utility model just provides and a kind ofly saves time, the push rod indexing mechanism of laborsaving, automatic displacement.
The utility model is following realization: the push rod indexing mechanism mainly is made up of push rod tooth bar, little axle, index dial, fork, ejector pin, slide block tooth bar, ratchet, ratchet, pawl axis, spring, gear, central shaft; Wherein: be with pawl axis, ratchet, ratchet, index dial on central shaft from inside to outside successively, circular index dial periphery evenly is provided with several open slots, ratchet periphery and the engagement of slide block tooth bar; Be with fork on the little axle of central axes, the affixed ejector pin of the other end of fork, ejector pin are inserted in the open slot of index dial, be provided with gear simultaneously on the little axle, gear and the engagement of push rod tooth bar, the push rod tooth bar is parallel with the slide block tooth bar, and the other end of push rod tooth bar is provided with spring.When needs index dial calibration, at first promote the push rod tooth bar and move by external force, push rod rack drives gear rotates, and the swing of gear upper pendulum bar drives ejector pin simultaneously and extracts from the open slot of index dial, breaks away from index dial; When the push rod tooth bar continues to move forward and slide block tooth bar engagement and promote the slide block tooth bar and compress spring simultaneously, slide block rack drives ratchet rotates, and ratchet then drives pawl axis, index dial rotates.When index dial forwards preposition to, the slide block tooth bar can not move forward, and at this moment, eliminates the motive force of push rod tooth bar, the push rod tooth bar is under the elastic force effect of spring, keep in the center, in the push rod tooth bar playback process, driven gear, fork, ejector pin are turned round in the other direction, ejector pin snaps in the next open slot of index dial, it is motionless that ratchet blocks pawl axis, and ratchet, slide block are turned back to original position, so just finished a calibration process.
Use the push rod indexing mechanism, simple in structure, compact, do not need power source, only need promote the push rod tooth bar with hand or mechanical device and just can finish calibration, whole process saves time, laborsaving, the accuracy height.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model front view:
Wherein: 1. index dial; 2. ejector pin; 3. fork; 4. little axle; 5. gear; 6. push rod tooth bar; 7. ratchet; 8. ratchet; 9. slide block tooth bar; 10. spring; 11. pawl axis; 12. central shaft;
As shown in Figure 1, the push rod indexing mechanism mainly is made up of push rod tooth bar (6), little axle (4), index dial (1), fork (3), ejector pin (2), slide block tooth bar (9), ratchet (8), ratchet (7), pawl axis (11), spring (10), gear (5), central shaft (12); Be with pawl axis (11), ratchet (8), ratchet (7), index dial (1) on central shaft successively, circular index dial (1) periphery evenly is provided with 8 open slots, ratchet (7) and slide block tooth bar (9) engagement; Be with fork (3) on the little axle (4) parallel with central shaft (12), the affixed ejector pin of the other end of fork (2), ejector pin is inserted in the open slot of index dial, be provided with gear (5) simultaneously on the little axle, gear and push rod tooth bar (6) engagement, the push rod tooth bar is parallel with the slide block tooth bar, and the other end of push rod tooth bar is provided with spring (10), and pawl axis and cutterhead or workpiece plate join.When the needs calibration, at first promote the push rod tooth bar and be moved to the left by external force, push rod rack drives gear rotates, and the swing of gear upper pendulum bar drives ejector pin simultaneously and extracts from the open slot of index dial, breaks away from index dial; When the push rod tooth bar continued to move forward, with slide block tooth bar engagement and promote the slide block tooth bar and slide left and compress spring simultaneously, the slide block tooth bar moved and drives ratchet simultaneously and rotate, and ratchet then drives pawl axis, index dial and rotates with cutterhead or workpiece plate that pawl axis joins.When index dial turned over 45 °, the push rod tooth bar put in place and can not move forward, and pawl axis is blocked by ratchet, can not turn round, at this moment, eliminate the motive force of push rod tooth bar, the push rod tooth bar is under the elastic force effect of spring, keep in the center, in the push rod tooth bar playback process, driven gear, fork, ejector pin are turned round in the other direction, ejector pin snaps in the next open slot of index dial, ratchet, slide block then are turned back to original position, and it is motionless that ratchet blocks pawl axis, and whole calibration process finishes.
