Utility model content
The purpose of this utility model is to provide the sub-device of a kind of automatic shuttle changing, to solve the defect that prior art shuttle change is wasted time and energy, production efficiency is low.
The utility model is realized by following scheme: comprise stock chest, handgrip mechanism, cam mechanism and pinion and rack; In described stock chest, be provided with extra shuttle; Described handgrip mechanism comprise on central shaft and central shaft, install can be along the shelves joint of its slip, described shelves joint is comprised of upper dish and lower wall, wherein lower wall week is upwards symmetrically installed two handgrips, the outside of lower wall be sleeved on back-moving spring on central shaft against; Described cam mechanism comprises and is positioned at the plane cam of slide plate one end and the roller coordinating with plane cam, and described roller connects on the side face of shelves joint lower wall by lever; Described pinion and rack comprise be positioned at the slide plate other end tooth bar and with tooth bar meshed gears, described gear is connected by non-return bearing with the central shaft in the upper dish of shelves joints outside; The described slide plate end that is provided with plane cam one side is provided with connecting rod, and connecting rod middle part is set with back-moving spring, end is provided with handle.
Such scheme can further be improved to:
Extra shuttle in described stock chest is a plurality of being arranged in order, and the outside of last extra shuttle and Compress Spring against.
The utility model has been realized the Automatic continuous operation of shuttle changing by the teamwork of handgrip mechanism, cam structure and pinion and rack, greatly improved the production efficiency of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
In figure: 1, stock chest, 2, extra shuttle, 3, lever, 4, roller, 5, handle, the 6, first back-moving spring, 7, slide plate, 8, plane cam, 9, tooth bar, 10, gear, 11, work shuttle, 12, rotating shuttle, the 13, second back-moving spring, 14, Compress Spring, 15, shelves joint (M, upper dish, N, lower wall), 16, lower shaft, 17, central shaft, A, work shuttle handgrip, B, extra shuttle handgrip.
The specific embodiment
Referring to Fig. 1, the sub-device of a kind of automatic shuttle changing, comprises stock chest 1, handgrip mechanism, cam mechanism and pinion and rack; In stock chest 1, be provided with extra shuttle 2, extra shuttle 2 is a plurality of being arranged in order, and the outside of last extra shuttle and Compress Spring 14 against; Handgrip mechanism comprise on central shaft 17 and central shaft 17 install can be along the shelves joint 15 of its slip, shelves joint 15 is comprised of upper dish M and lower wall N, wherein lower wall N week symmetrical two handgrips (work shuttle handgrip A and extra shuttle handgrip B linearly horizontal distribution at gear Jie15 two ends) of installing upwards, the outside of lower wall N be sleeved on the second back-moving spring 13 on central shaft 17 against; Cam mechanism comprises and is positioned at the plane cam 8 of slide plate 7 one end and the roller 4 coordinating with plane cam 8, and roller 4 connects on the side face of shelves joint lower wall N by lever 3; Pinion and rack comprise be positioned at slide plate 7 other ends tooth bar 9 and with tooth bar 9 meshed gears 10, gear 10 is connected by non-return bearing with the central shaft 17 in the upper dish of shelves joints M outside; Slide plate 7 ends that are provided with plane cam 8 one sides are provided with connecting rod, and connecting rod middle part is set with the first back-moving spring 6, end is provided with handle 5.Need to further illustrate: because upper dish M and lever 3 is fixing, therefore can not rotate around central shaft 17, lower wall N and work shuttle handgrip A, extra shuttle handgrip B fix, can rotate around central shaft 17, gear 10 is connected by non-return bearing with central shaft 17, be gear 10 while counterclockwise rotating, do not drive central shaft 17 and gear joint lower wall N to rotate; When gear 10 rotates clockwise, drive central shaft 17 and gear joint lower wall N and handgrip to rotate.
This device operation principle: after each parts are connected, the position of adjustment work shuttle handgrip A and extra shuttle handgrip B, make it corresponding with rotating shuttle 12 and stock chest 1 respectively,, when shelves joint 15 moves back and forth along central shaft 17, two handgrips can take out respectively work shuttle 11 and extra shuttle 2; During work, pull out handle 5, slide plate 7 and the plane cam 8 being fixed on slide plate 7 are pulled, and the tooth bar 9 being connected with slide plate 7 is also pulled that (now gear 10 rotates counterclockwise, due to non-return bearing on axle 17 do not rotate, and two handgrips do not rotate); Plane cam 8 promotes the lever 3 of roller 4 is housed, thereby makes work shuttle handgrip A, extra shuttle handgrip B move forward and capture respectively work shuttle 11 and extra shuttle 2; Decontrol handle 5, slide plate 7 is got back to original position under the effect of the first back-moving spring 6, and plane cam 8 and tooth bar 9 also reset simultaneously.Now two handgrips are drawn back under the effect of the second back-moving spring 13, simultaneously, because making gear 10, tooth bar 9 turns clockwise, gear 10 drives shelves joint lower wall N to rotate by central shaft 17, make work shuttle handgrip A, extra shuttle handgrip B turn clockwise respectively 180 °, in rotary course, work shuttle handgrip A throws the work shuttle of taking-up 11 to pass in collector.And then while pulling handle 5, extra shuttle handgrip B relies on rotating shuttle 12 and extra shuttle 2 is inserted in shuttle framves 12, work shuttle handgrip A can not take out extra shuttle from stock chest 1.Finally decontrol again 5, two handgrip Rotate 180s ° of handle and be returned to original position.
