The electromagnetic braking press device of name plate marking machine
Technical field
The present invention relates to the nameplate hold down gag of a kind of name plate marking machine when mark is known, especially a kind of electromagnetic braking press device of name plate marking machine.
Background technology
Product is equipped with the nameplate of printed words such as printing the date of production, specifications and models on product before dispatching from the factory.In the print procedure of product nameplate sign, the method that compresses nameplate generally is to pin nameplate with two fingers to operate.The shortcoming of this method be compress not firm, be easy to play, cause the nameplate print position inaccurate, and do not note slightly also can stabbing finger.Known mark is known the device that compresses nameplate and is also had two kinds of vacuum chuck device, mechanical clamping devices.Vacuum chuck device: high-precision vacuum tables need be set, be covered with many vacuum on the workbench and inhale the hole, nameplate is inhaled on the workbench surface during operation, but vacuum cup has gas leakage just can not work slightly, also need vavuum pump can not stop to vacuumize simultaneously, and the cost of this device is also very high; Mechanical clamping device: on its workbench surface locating piece and lateral compressing block are installed, eccentric shaft and set lever thereof are installed on the compact heap, also be shaped on an array pitch on the workbench from adjustment hole, must at first move the position of adjustment pressing handle during this device operation according to the size of nameplate, manually pressing handle carries out the mark knowledge after compressing nameplate again, not only loaded down with trivial details but also inconvenient, particularly undersized nameplate is not firm because of its thin thickness pressure, can not guarantee normally carrying out of mark knowledge work.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of reliably, the electromagnetic braking press device of name plate marking machine efficiently.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of electromagnetic braking press device of name plate marking machine, comprise base, be installed in the workbench on the base, be installed in the nameplate locating piece on plane on the workbench, and the hold down gag that is used to compress nameplate, described hold down gag is that the holder that has centre bore is installed on base, the electromagnetism electricity loss brake that has centre bore is installed on the holder, in the electromagnetism electricity loss brake solenoid is installed, moving plate, friction plate and stage clip, the locating shaft that can move up and down in the centre bore of electromagnetism electricity loss brake is being installed on the friction plate of electromagnetism electricity loss brake, the upper end of locating shaft is shaped on threaded rod, adjusting nut is installed on the threaded rod, movable depression bar is installed on threaded rod, the front end of movable depression bar is equipped with the compact heap that compresses nameplate, and the rear end of movable depression bar is shaped on and the hole of threaded rod coupling and the groove that mates with adjusting nut.
The present invention can also adopt following technical scheme:
Described threaded rod and adjusting nut all are shaped on the fine thread that is complementary.
Advantage and good effect that the present invention has are:
Because the holder that has centre bore is installed on base, the electromagnetism electricity loss brake that has centre bore is installed on the holder, in the electromagnetism electricity loss brake solenoid is installed, moving plate, friction plate and stage clip, the locating shaft that can move up and down in the centre bore of electromagnetism electricity loss brake is being installed on the friction plate of electromagnetism electricity loss brake, the upper end of locating shaft is shaped on threaded rod, adjusting nut is installed on the threaded rod, movable depression bar is installed on threaded rod, the front end of movable depression bar is equipped with the compact heap that compresses nameplate, the rear end of movable depression bar is shaped on and the hole of threaded rod coupling and the groove that mates with adjusting nut, outage by the electromagnetism electricity loss brake and energising are controlled compressing of movable depression bar and are loosened, and have solved manual operation inconvenience and fixing illusive problem; In addition the present invention also have simple in structure, be easy to make, the advantage of convenient and reliable operation, high efficiency.

Fig. 2 is that the A of Fig. 1 is to view.
Among the figure: 1, compact heap; 2, screw; 3, movable depression bar; 4, adjusting nut; 5, locating shaft; 6, solenoid; 7, moving plate; 8, friction plate; 9, holder; 10, stage clip; 11, workbench; 12, base; 13, bolt; 14 locating pieces; 15, centre bore; 16, electromagnetism electricity loss brake; 17, groove; 18, bolt.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, by bolt 13 installment work platforms 11, one of the plane jiao is equipped with the square locating piece 14 that is used for the nameplate location on workbench, as shown in Figure 2 on base 12.The hold down gag that compresses nameplate also is installed on base, this hold down gag is by bolt 18 holder 9 that has centre bore 15 to be installed on base, the electromagnetism electricity loss brake 16 that has centre bore is installed on the holder, solenoid 6, moving plate 7, friction plate 8 and stage clip 10 are installed in this electromagnetism electricity loss brake.The locating shaft 5 that can move up and down in the centre bore of electromagnetism electricity loss brake is being installed on the friction plate of electromagnetism electricity loss brake, the upper end of locating shaft is shaped on threaded rod, adjusting nut 4 is installed on the threaded rod, threaded rod and adjusting nut adopt fine thread, can do the adjustment of distance element like this, also be beneficial to the self-locking of adjusting nut.Be movably installed with movable depression bar 3 on threaded rod, the front end of movable depression bar is equipped with the compact heap 1 that compresses nameplate by screw 2, and the rear end of movable depression bar is shaped on and the hole of threaded rod coupling and the groove 17 that mates with adjusting nut.Outage that like this can be by the electromagnetism electricity loss brake and energising are controlled compressing of movable depression bar and are loosened, and have solved manual operation inconvenience and fixing illusive problem, and operating efficiency is improved greatly.
Operation principle:
Gauge tap disconnection, dead electricity when needs compress nameplate, electromagnetism electricity loss brake 16 discharges, and stage clip 10 compresses moving plate 7, and moving plate promotes locating shaft 5, and locating shaft drives rotatable movable depression bar 3, compact heap 1, compresses nameplate.After the nameplate sign had been beaten, gauge tap was connected, gets electric, the adhesive of electromagnetism electricity loss brake, and stage clip is by the moving plate reverse compression, and moving plate and locating shaft are thrown off, and movable depression bar lifts and loosens the nameplate that is marked and knows, and its movable depression bar can arbitrarily rotate.The nameplate that more renew this moment is done mark knowledge work again.
