Wherein, described tooth bar with the piston rod of straight line cylinder for being threaded.
Wherein, described gear is provided with a pin-and-hole and a screw, and described ratchet and spring clamp are arranged on pin-and-hole and screw by step pin and bolt.
Wherein, described rotating shaft is connected with ratchet by flat key.
Wherein, described rotating shaft is connected with cylinder by flat key.
Wherein, on described step pin, be also provided with circlip for shaft.
Beneficial effect: compared with prior art, the utlity model has following advantage: the clearance-type pay-off that the utility model provides, operate steadily, reliability is high, failure rate is low, can periodically carry and stop part to be processed, give manipulator a fixing crawl position, potential difference is less, and location is reliable, be particularly useful for batch manufacturing, improve automation performance, raising production efficiency and the quality of lathe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A cutaway view in Fig. 1;
Fig. 3 is ratchet structure schematic diagram;
16-part in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to figs. 1 through Fig. 3, a kind of clearance-type pay-off, comprises mounting bracket 1, gear case 2, straight line cylinder 3 and rotating shaft 4; Described gear case 2 is arranged on mounting bracket 1, in described gear case 2, be also provided with a pair of pitch wheel 5 and tooth bar 6, described straight line cylinder 3 is arranged on gear case 2, and the piston rod of straight line cylinder 3 is connected with tooth bar 6, on described gear 5, be also provided with ratchet 7 and spring clamp 8, described rotating shaft 4 is arranged in gear case 2, and one end of rotating shaft 4 is provided with the ratchet 9 being used in combination with ratchet 7, and the spring leaf of described spring clamp 8 makes that ratchet 7 is elastomeric to be attached on ratchet 9, and spring clamp 8, ratchet 7 and ratchet 9 threes form pawl structures; In described rotating shaft 4, be also provided with cylinder 10, on described cylinder 10, be also wound with load-transfer device 11; The track afterbody that the tooth bar 6 of described gear case 2 moves is also provided with end cap 12, is also provided with spacing set screw 13 on described end cap 12.Described tooth bar 6 with the piston rod of straight line cylinder 3 for being threaded.Described gear 6 is provided with a pin-and-hole and a screw, and described ratchet 7 and spring clamp 8 are arranged on pin-and-hole and screw by step pin 14 and bolt.Described rotating shaft 4 is connected with ratchet 9 by flat key 14.Described rotating shaft 4 is connected with cylinder 10 by flat key 14.On described step pin 14, be also provided with circlip for shaft 15.
The utility model is in the time of work, as shown in Figure 1, after straight line cylinder starts, piston rod advances and is with carry-over bar to move left, the gear being meshed with it clockwise rotates, gear driven ratchet and spring card rotate, the shell fragment of spring card squeezes ratchet to be attached on ratchet, gear clockwise rotates, ratchet is pushing away ratchet and is clockwise rotating with gear, ratchet and rotating shaft are to be connected together by a flat key of its right-hand member, and rotating shaft and cylinder are also by left, in two flat keys be connected, transport tape is installed on cylinder again, ratchet drives again rotating shaft rotation after rotating under the drive of ratchet, rotating shaft drives cylinder to clockwise rotate, transport tape advances with regard to conveying parts like this, until tooth bar stops after encountering the spacing set screw on end cap, be that feeding finishes.
Spacing set screw on end cap can capture according to manipulator the position adjustment of part, after adjustment with nut locking.The solenoid directional control valve of switching controls cylinder make the piston rod of straight line cylinder retreat band carry-over bar move right, the gear being meshed with it rotates counterclockwise, ratchet rotates counterclockwise along the arc surface of ratchet voluntarily with gear, ratchet remains static, transport tape on rotating shaft and cylinder all remains static, part also captures part in static wait manipulator, and the feeding process in such gap is complete.In the time that cylinder again advances, retreats, repeat a upper process part stops again after previous feeding position.
Clearance-type of the present utility model refers to that when straight line cylinder advances, transport tape conveying parts is to previous fixing distance, and when straight line cylinder retreats, transport tape remains static.The stroke adjustment that the distance that part advances can be advanced by controlling straight line cylinder, straight line cylinder promotes tooth bar and advances after encountering the spacing set screw on end cap and stop, the front and back position capable of regulating of this spacing set screw, adjusts to after ideal position with nut locking.Clearance-type feeding can utilize time (being transport tape rest time) that cylinder retreats by steadily feeding of manipulator, standing time is the time that straight line cylinder retreats, and straight line cylinder retreats the time and can control by the governor valve at adjusting cylinders two ends.
The foregoing is only preferred embodiments of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skill in the art do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of recording in claims.
