Description

The tooth roller structure

Technical field

The utility model relates to tooth roller, refers to a kind of variation that utilizes eccentric throw between swing arm and rotating shaft especially, changes the movement travel of swing arm, to adjust the tooth roller structure of feeding rod speed.

Background technology

Referring to shown in Figure 8, the primary structure of known tooth roller, be that group is established a drive link 21 on board 2, utilize the belt pulley 211 of these drive link 21 1 ends to connect power source, trace 21 is rotated, utilize the pinion 212 on the drive link 21 to be engaged in gear wheel 22 again, make with the affixed rotating shaft 23 of gear wheel 22 rotate thereupon together with the feeding cam 231 that its other end sets firmly, by gear wheel 22 drivening rods 221, make the slide block 24 that is connected in connecting rod 221 do up and down reciprocatingly to slide simultaneously; In addition, this feeding cam 231 contacts at the roller 251 of swing arm 25, make this swing arm 25 along pivot 252 swings, these swing arm 25 bottoms are articulated in feeding rod 26, this feeding rod 26 can be moved around fast with the swing of swing arm 25, and these feeding rod 26 other ends are connected in threading group 27, and then this threading group 27 can be with its shift reciprocately, to carry out the processing of thread.

Referring to shown in Figure 9, this feeding rod 26 is sheathed in two axle sleeves 261,262 of board 2, is arranged with spring 263 and ring set 264 on this section feeding rod 26; One end of this spring 263 and board 2 inwalls hold, the other end then is held in ring set 264, and screw togather by bolt 265 and to be fastened in the locating hole 266 many on this feeding rod 26, and this ring set 264 is positioned on the feeding rod 26, make this feeding rod 26 have left strong elastic, with the swing arm 25 that cooperation swings back and forth, feeding rod 26 is moved back and forth smoothly.

When desire changes feeding speed, directly unscrew bolt 265, mobile again ring set 264, to change the compressive state of spring 263, nationality can be adjusted the feeding speed of feeding rod 26 by the length of the resetting time that variation produces of spring 263 DE, promptly working as spring 263 is compressed more, the elastic reset time is short more, and then feeding speed is fast more, otherwise then slow more.

Yet the adjustment structure of above-mentioned feeding speed has many disappearances on reality is used, as:

1, the elastic force of spring 263 is quite big, quite effort and inconvenience when manually ring set 264 being pushed to the right.

When 2, unscrewing bolt 265, brute spring 263 springing of these ring set 264 brute forces can being turned left careless slightlyly promptly may cause the accident of hurting sb.'s feelings.

3, hold as brute force with spring 263, in moving back and forth fast, be easy to cause the resonance resilience, and influence the accuracy of displacement and operation.

4, owing to utilize to adjust the speed that the elasticity of spring 263 changes its recovery, reach the feeding speed of adjusting feeding rod, but because of with the speed that variation was produced of spring restoring force soon, limited slowly, therefore, can't fill part needs that satisfy practical operation.

5, because of its feeding cam 231 appearance relations own, except that need with roller 251 in the swing arm 25 matches, the relative position of feeding cam 231 and roller 251 still needs match with spring 263, therefore, comparatively trouble and inconvenience in the assembling.

6, after spring 263 long-time the uses, will produce elastic fatigue, and influence movement velocity.

Summary of the invention

In view of this I at the disappearance of known tooth roller existence, and explored, designed, and through testing repeatedly and assessing, develops the utility model finally.

Main purpose of the present utility model is to provide a kind of tooth roller structure, and it utilizes the eccentric throw between swing arm and rotating shaft to change, and changes the movement travel of swing arm, adjusts the speed of feeding rod.

A kind of tooth roller structure of the present utility model, comprise a board, it is characterized in that: this board is provided with one by the drive link of power source through the belt pulley transmission, driving gear on this drive link and the engagement of the driven gear on the trace, be fixed on gear wheel in the rotating shaft by the pinion on the trace one again, this rotating shaft one end sets firmly a runner with slide, establish a chute that slide block is housed in this slide, this slide one end sets firmly a fixed block, one adjustment bolt passes fixed block and slide block screws togather, rotate the eccentric position of this adjustment bolt adjustable slide in chute, in addition, articulate a swing arm on this slide block, the other end of this swing arm is connected with rotating cylinder by spherical bearing, the end of exerting oneself of this rotating cylinder is articulated in feeding rod by a double-action plate, and this feeding rod is connected in the threading group, and two ends of this feeding rod then pass two axle sleeves from board respectively, and be provided with linear bearing among each axle sleeve, the threading group of joining with interlock and feeding rod; In addition, chute two sides of this slide are provided with the adjustment hole of symmetry, pass and are locked on the runner by screw tightening, to adjust the eccentric position of the relative runner of slide.Wherein:

Described slide block end face epirelief is provided with a locking projection, and this locking projection cooperation one locking ring is fixed in the slide block spiral shell among the chute of slide.

Described locking projection is provided with the thread segment that is complementary with the ring that locks.

Advantage of the present utility model is:

1. because the utility model utilizes slide and the slide block eccentric position on runner, adjust the movement velocity of threading group, therefore, in threading group reciprocating motion process fast, the control of its speed comparatively precisely, clearly.

2. because the utility model utilizes screw tightening and locking part locking slide and slide block respectively, so, more or less freely, convenient when adjusting the eccentric position of slide and slide block.

3. adjust the movement velocity of threading group because of the utility model utilizes slide and the slide block eccentric position on runner again, therefore, the adjusting range of its speed is bigger, and can not be subjected to the restriction of spring restoring force as known tooth roller.

4, because the movement velocity of threading group is only relevant with slide and the eccentric position of slide block on runner, therefore, after slide block and slide were locked, the movement velocity of threading group just was fixed, and no longer is subjected to the influence of other factors.

Again because of the utility model by locking ring and screw tightening locking slide block and slide, therefore, unscrewing locking ring and screw tightening, when adjusting slide block and slide or screwing locking, do not have the contingency of hurting sb.'s feelings and take place, so quite safe.
