Abstract

The utility model relates to a mechanical counter matched with a plate shearing machine, which comprises three or four word wheels (20) and (34) and a multi-stage interval wheel set composed of gears (26, 29, 30) and intermediate wheel shafts (19, 32) arranged between word wheel shafts from the second bit to the final bit. The utility model is characterized in that the mechanical counter matched with a plate shearing machine is provided with a worm screw (3), a worm wheel (22) and a speed reducer, wherein, the top part of the worm screw (3) is provided with a bevel gear (9), the bevel gear (9) is engaged with a bevel gear (8) on the word wheel shaft at the first bit, and a driving wheel (23) which is coaxial with the worm wheel (22) is engaged with the gear (26) on the word wheel shaft at the second bit. The utility model can be matched with the plating shearing machine and a bender, initial velocity can reach 1730 circles per minute, and the mechanical counter matched with a plate shearing machine has the advantages of compact structure, small volume, accurate measurement, firmness and reliability.

Description

Counter matched with shear

The utility model relates to a kind of mechanical counter.

When using equipment such as big-and-middle-sized plate shearing machine, bender,, all need be equipped with counter in order to survey the size of reading workpiece.The input shaft that the motor shaft of plate shearing machine or bender drives counter rotates, thereby the reading of counter can reflect the size of the workpiece that changes with the motor shaft revolution.The existing mechanical counter generally is made up of 3 or 4 character wheels, and the wheels of being made up of many gears and axle of carrier pulley at multistage intermittence are housed between print wheel shaft, to realize the carry of transmission and reading.Only by gear drive, its velocity ratio is restricted this mechanical counter, and because the many volumes of gear are big, is damaging easily in the transmission fast.Existing counter input shaft rotating speed is slow, can't directly match with the motor speed (about 1700 rev/mins) of plate shearing machine or bender.

The purpose of this utility model provides a kind of and the counter plate shearing machine adapted, and it can remedy the above-mentioned deficiency of existing machinery counter.

The utility model comprises 3 or 4 character wheels, they all be fixed on separately the axle on, at second to the wheels of being made up of gear and axle of carrier pulley at multistage intermittence are housed between the print wheel shaft of end position, it is characterized in that being equipped with worm gear reducer, conical gear is equipped with at the top of worm screw, the engagement of conical gear on the latter and the first print wheel shaft is with the gearing mesh on the coaxial power wheel of worm gear and second print wheel shaft.

The utility model is slowed down by worm and gear, 1730 rev/mins of first scooters, can with the motor adapted of plate shearing machine, bender, compact conformation, volume is little, surveys and to read accurately, the error of indication is ± 0.1 millimeter, and is solid and reliable.

Further specify the utility model below by embodiment and accompanying drawing.

Accompanying drawing 1 is the structural representation of looking up of an embodiment of the utility model.

Accompanying drawing 2 is its side-looking structural representation.

Accompanying drawing 3 is its main TV structure synoptic diagram.

1 counter shell in the accompanying drawing, 2 counter covers, 3 worm screws, 4 worm screw seats, 5,15 sunk screws, 6 word window transparent panels, 7 word window covers, 8,9 conical gear, 10 first print wheel shafts, 11 grades of pads, 12,14 opening ring washers, 13 oiliness bearings, 16 bearings, 17 reeds, 18 ratchets, 19 first axle of carrier pulley, 20 the first character wheels, 21 steel wire eckbands, 22 worm gears, 23 power wheels, 24,27 pads, 25 little axles, 26,300 gears, 28 spacers, 29 single-tooth gears, 31 gear sheets, 32 second axle of carrier pulley, 33 screws, 34 character wheels.Wherein worm screw (3) is 4 line worm screws, and it and 20 tooth worm gears (22) mesh, and so just can make rotating speed slow to 1/5.Worm gear (22) is integral with little axle (25), and little axle (25) lower end sticks with glue knot and fixes one 5 tooth nylon power wheels (23), and the latter promotes second character wheel by ten gears (26) and rotates.A conical gear (9) is adorned at the top of worm screw (3), the latter and conical gear (8) engagement that is fixed on the first print wheel shaft (10), and both numbers of teeth are identical.Like this, the rotating ratio of input shaft and the first character wheel (20) is exactly 1:1.Worm screw (3) is fixed on the shell (1) of counter by oiliness bearing (13) and worm screw seat (4), at second to the wheels of being made up of single-tooth gear (24), axle of carrier pulley (19), (32) and ten gears (30) etc. at multistage intermittence are housed between the character wheel of end position, so as to reaching transmission and decimal purpose.

When using the utility model, worm screw (3) can be connected with the motor shaft of plate shearing machine by flexible axle.This motor shaft drives the first character wheel (20) by 4 line worm screws (3) and does to rotate with speed, and by 4 line worm screws (3), 20 tooth worm gears (22), second character wheel rotation of 10 gears (26) drive, rotate by all the other character wheels of other gear driven again, to realize the purpose of transmission and carry.
