Description

Wire cutting machine tool wrapping wire device

The utility model relates to the molybdenum filament wind that a kind of wire cutting machine tool uses, and especially relates to a kind of wire cutting machine tool wrapping wire device.

In the wire cutting machine tool course of work, often to cut molybdenum filament and unload by installation and dismantling to line.Normally assist to finish by weighing apparatus torque motor and control circuit, when carry out molybdenum filament by the dress operation time, rely on the molybdenum filament on the countertorque tension wire wrapping wheel of weighing apparatus torque motor, the wire storage tube that drives on the lathe is wound into molybdenum filament on the wire storage tube; As molybdenum filament being unloaded, rely on the weighing apparatus torque motor to drive wire wrapping wheel and rotate, molybdenum filament is wound on the wire wrapping wheel.This wire winding device must be provided with the weighing apparatus torque motor, the cost height, therefore having only high-grade wire cutting machine tool configuration ordinary lines cutting off machine is by manually-operated, the very inconvenience of mounting or dismounting molybdenum filament, when the dismounting molybdenum filament twines back wire wrapping wheel, can make molybdenum filament be deposited in a zonule, twine uneven, folded silk and sleave easily take place, and molybdenum filament is damaged.

The purpose of this utility model provides a kind of weighing apparatus torque motor and control circuit of not using can unload molybdenum filament by installation and dismantling, and during the dismounting molybdenum filament, molybdenum filament can evenly distributed twine back the wire cutting machine tool wrapping wire device of wire wrapping wheel.

For achieving the above object, the utility model comprises wire wrapping wheel, and wire wrapping wheel is installed in an end of main shaft; It also is provided with a magnetic tape trailer shell, is installed in the other end of main shaft, on the main shaft in the shell cam, large and small gear and spring take-up is housed successively; Be provided with power transmission shaft in the shell, little, gear wheel be housed on the power transmission shaft in the shell mesh in twos with gear on the driving shaft, an end of power transmission shaft passes shell by adorning handle; Cam drives the shift fork swing by the shift fork connecting rod, and molybdenum filament is evenly arranged by shift fork and is wrapped on the wire wrapping wheel; In order to make the utility model wrapping wire device, can be fixed on during work on the guide frame of wire cutting machine tool, the afterbody of shell is established a clamping device.

For to wire cutting machine tool by dress during molybdenum filament main shaft can produce moment of friction, the molybdenum filament that wire wrapping wheel is emitted obtains a tensile force that weighing apparatus is fixed, on main shaft, establish a spring take-up, promptly pass main shaft and adorn a friction plate, near a friction spacing ring on chip, spacing ring fixedly is installed on the main shaft, establish a spring at friction plate with by between the gear of friction plate, one end of shell is provided with is with protruding folding and unfolding silk switch, uniform four bayonet sockets on the periphery of friction plate, the size of bayonet socket, shape and folding and unfolding silk switch protruding corresponding.

Can stable operation during for the folding and unfolding silk, establish a clamping device at the afterbody of shell, one side, be fixed on the guide frame of wire cutting machine tool by the spiral push rod during folding and unfolding silk promptly at the C type bayonet socket of establishing of shell afterbody.

The utility model simple structure, easy to use, when on wire cutting machine tool, unloading molybdenum filament, needn't assist finish, and molybdenum filament can evenly distributed wraparound wire wrapping wheel during the dismounting molybdenum filament by weighing apparatus torque motor and control circuit by mounting or dismounting.

Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural principle schematic diagram.

Fig. 2 be among Fig. 1 member 12 and 13 A to view.

2 is the utility model wire wrapping wheels among the figure, is installed in an end of main shaft 14, and the other end of main shaft 14 is by adorning a magnetic tape trailer shell.On the main shaft 14 in the shell 8 cam 15,

gear

17,16, spring 21, wearing piece 12 and spacing ring 11 are housed successively,

gear

17,16 meshes in twos with

gear

20,18 respectively,

gear

20,18 is installed on the power transmission shaft 19, and an end of power transmission shaft 19 passes shell 8 by dress handle 9.The both sides of shell 8 are provided with bearing 10, and main shaft 14, power transmission shaft 19 are installed on the shell 8 by bearing 10 respectively.Cam 15 drives shift fork 3 swings by shift fork connecting rod 4, and molybdenum filament 1 is entangled on the wire wrapping wheel 2 by shift fork 3.One end of shell 8 is established one and is with protruding folding and unfolding silk switch 3, all establishes four bayonet sockets on the periphery of friction plate 12, the size shape of bayonet socket and folding and unfolding silk switch 13 protruding corresponding.The afterbody of shell 8 is established a C type bayonet socket 6 on one side, is fixed on the wire cutting machine tool guide frame 5 by spiral push rod 7 during use.

During use, by C type bayonet socket 6 and spiral push rod 7 the utility model wrapping wire device is fixed on the wire cutting machine tool guide frame 5, when from wire wrapping wheel 2 to wire cutting machine tool by dress during molybdenum filament 1, stir folding and unfolding silk switch 13 earlier, the projection of folding and unfolding silk switch 13 is inserted in the bayonet socket of friction plate 12, as shown in Figure 2.At this moment, friction plate 12 is stuck, the effect of holding out against owing to spring 21 between friction plate 12 and the spacing ring 11 produces a frictional force, because spacing ring 11 fixedly is installed on the main shaft 14, the frictional force that produces between itself and the friction plate 12 is passed to main shaft 14, from wire wrapping wheel 2, molybdenum filament 1 is connected on the wire storage tube of wire cutting machine tool, rotate wire storage tube, rely on the moment of friction on the main shaft, make molybdenum filament 1 obtain a weighing apparatus and decide tension force and reach tight wrapping wire; When from wire storage tube dismounting withdrawal molybdenum filament 1, earlier folding and unfolding silk switch 13 is transferred to from the bayonet socket of friction plate 12, at this moment, friction plate 12 suspends, the spring take-up zero load, main shaft 14 can rotate flexibly, molybdenum filament 1 is passed from the wire storage tube the breach of shift fork 3, be wound on the wire wrapping wheel 2 turning handle 9, power transmission shaft 19 is rotated, drive pinion 16 by gear wheel 18 and make main shaft 14 and wire wrapping wheel 2 quick rotation, simultaneously, the pinion 20 on the power transmission shaft 19 drives gear wheel 17 and cam 20 slow rotation that are slidingly connected with main shaft 14, make cam 15 drive shift fork connecting rod 4 and shift fork 3 reciprocating motions, molybdenum filament 1 is being arranged on the wire wrapping wheel 2 under the stirring of shift fork 3 uniformly.
