Technical field
The utility model relates to computer embroidery machine technology, particularly relates to the mounting structure of the magnetic upper thread checkout gear of computer embroidering machine.
Background technology
Magnetic upper thread checkout gear can detect the faults such as the broken string on computerized emboridering machine, false embroidery.Magnetic upper thread checkout gear is primarily of permanent magnet and magnetic sensor chips composition, and permanent magnet is fixed on through on the wire-crossing wheel axle on tension seat panel, and can rotate with wire-crossing wheel axle.When there is the fault such as broken string, false embroiderys, wire-crossing wheel axle understand stall or rotating speed slack-off, magnetic sensor chips can detect fault according to the changes of magnetic field of permanent magnet.
But, magnetic upper thread checkout gear is very high for the requirement of installation accuracy, when requiring computerized emboridering machine in running order (now tension seat panel is along with needle bar frame left and right transverse shifting), the permanent magnet be arranged on each wire-crossing wheel axle all can just to magnetic sensor chips, and error up and down can not more than 0.15mm.And the area of permanent magnet and magnetic sensor chips is very little, itself also lacks positioning datum, is again to be simultaneously arranged on respectively on two different parts, the center of permanent magnet therefore will be made to aim at the center of magnetic sensor chips be the thing that very difficult.Just because of this, the mounting structure of existing magnetic upper thread checkout gear is difficult to meet above-mentioned required precision, causes often there will be the phenomenons such as undetected, flase drop.
Summary of the invention
Technical problem to be solved in the utility model is the mounting structure of the magnetic upper thread checkout gear providing a kind of computer embroidering machine, when it can ensure that computerized emboridering machine is in running order, the permanent magnet be arranged on each wire-crossing wheel axle all can just to magnetic sensor chips, and be easy to realize.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The mounting structure of the magnetic upper thread checkout gear of computer embroidering machine, comprises head, tension seat and magnetic upper thread checkout gear; Tension seat is fixed on the needle bar frame of computerized emboridering machine, and can move left and right with this needle bar frame; This tension seat comprises tension seat panel and is somely drained through wire wheel axis, and each wire-crossing wheel axle is through tension seat panel; Magnetic upper thread checkout gear comprises polylith permanent magnet, and this polylith permanent magnet is arranged on one end that many wire-crossing wheel axles are positioned at tension seat back side of panel side correspondingly, and each permanent magnet can rotate with the wire-crossing wheel axle of correspondence; Wherein, this magnetic upper thread checkout gear also comprises and is arranged on some some row's permanent magnets some pieces of magnetic sensor chips be one to one drained through on wire wheel axis, and described tension seat panel is provided with positioning through hole; Described mounting structure also comprises tension seat moving guiding mechanism, chip mount pad and positioning base; Chip mount pad is positioned at tension seat back side of panel side, and is removably interconnected with positioning base; Some pieces of magnetic sensor chips are arranged on chip mount pad, and this tension seat can only move left and right relative to chip mount pad under the guide effect of tension seat moving guiding mechanism; Chip mount pad is also provided with mounting-positioning holes; Positioning base is fixed on head; Each magnetic sensor chips when positioning through hole aims at mounting-positioning holes, just to any one piece of permanent magnet in that row's permanent magnet corresponding.
The utility model at least has following technique effect:
1, mounting structure of the present utility model is respectively equipped with positioning through hole and mounting-positioning holes on tension seat panel and chip mount pad, when permanent magnet is identical relative to the position relationship of mounting-positioning holes with magnetic sensor chips relative to the position relationship of positioning through hole, as long as positioning through hole and mounting-positioning holes targeted by, so permanent magnet and magnetic sensor chips are also just right with regard to realizing, and realize positioning through hole and mounting-positioning holes aim at than directly aim at permanent magnet and magnetic sensor chips much easier, as long as first utilized outside alignment pin to insert in positioning through hole and mounting-positioning holes before computerized emboridering machine work just can correct location in advance simultaneously.Before alignment pin being inserted in positioning through hole and mounting-positioning holes, the connection between positioning base and chip mount pad is first made to unclamp, now due to the guide effect of tension seat moving guiding mechanism, also can only relatively move left and right between chip mount pad with tension seat panel, and can not front and back or relative movement up and down.After alignment pin being inserted in positioning through hole and mounting-positioning holes, then be fastenedly connected between positioning base and chip mount pad, thus complete correction location.After completing correction, computerized emboridering machine work, rely on the guide effect of tension seat moving guiding mechanism, the permanent magnet be arranged on each wire-crossing wheel axle can be kept still just to magnetic sensor chips, thus probability that is undetected and flase drop can be reduced;
2, when embroidery machine run to be in stopped status after a period of time time; alignment pin can be inserted again in positioning through hole and mounting-positioning holes; the phenomenon of inserting not enter as occurred; then illustrate that magnetic sensor chips is not just to permanent magnet; need again to carry out correction location to the position of chip mount pad, therefore mounting structure of the present utility model is also extremely convenient to follow-up verification.
