Abstract
The utility model relates to an overload safeguard for a machine tool automatic feeder, comprising a motor 1, an input gear 2 and an output gear 3. The output gear 3 drives an output axis 4 to output power, the output gear3 matches with the gap of the output axis4. The output gear3 forms a magnetic conductivity capacitance groove 31 along with the axis direction. An electric coil 5 is sleeved on the output axis 4 and is arranged on the capacitance groove 31 and a magnetic conductivity connecting rotary table 6 which drives together with the output axis 4 is arranged at the contacted position between the output axis4 and capacitance groove 31. The connecting rotary table 6 is fixedly connected with a straight iron table 61 and connecting table 62, wherein, the connecting table 62 extends along with the axis direction to form a groove 621 and a through hole 41 is corresponding with the groove 621 at the output axis 4 and an inserted link 7 is inserted into the position of the groove 621 by the through hole 41; thereby, with the structure, the original abrasion and the mechanical failure of snaggletooth can be solved.
Description
The utility model relates to a kind of protective device of machine tool feed device, and is particularly relevant with a kind of lathe autofeed device overload protection arrangement.
The automatic feeder of commonly using as shown in Figure 1, motor 1 drives input gear 2 and rotates, output gear 3 with 2 engagements of input gear, drive the output shaft outputting power by output gear 3, because this output helical gear 3 directly is rigidly connected with output shaft, the work by the frequent forward and backward of screw rod on a pair of bevel gear drive workbench makes this gear frequent operation under the on-load situation for a long time, very easily produce fatigue wear or broken teeth, break down.
At above-mentioned defective, the purpose of this utility model is to provide a kind of lathe autofeed device overload protection arrangement, and it can prolong the service life of output gear greatly, and can prevent the generation of broken teeth.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of lathe autofeed device overload protection arrangement; comprise input gear 2 that motor 1, motor 1 drive, with the output gear 3 of input gear 2 engagements, drive output shafts 4 outputting powers by output gear 3; described output gear 3 and output shaft 4 matched in clearance; and on described output gear 3, form a magnetic conductivity storage tank 31 vertically; one hot-wire coil 5 is set on the output shaft 4 and is arranged in the storage tank 31, in addition is fixed with one in addition with joint place, storage tank 31 bottom surface on output shaft 4 and is connected rotating disk 6 with the magnetic conductivity of output shaft 4 unitary rotation.
Described connection rotating disk 6 is by an absorption pure iron dish 61 and 62 affixed compositions an of terminal pad, wherein, terminal pad 62 radially forms a groove 621 along the axle center, pass this through hole 41 and be plugged on location in the described groove 621 at 621 places of respective slot on the output shaft 4, one through hole, 41, one inserted links 7.
Be provided with the elastic buffer pin 8 that can make both fine motions between described absorption pure iron dish 61 and the terminal pad 62.
After adopting said structure, because output gear 3 becomes indirect the connection with output shaft, coil electricity in clutch, make magnetic conductivity storage tank 31 produce magnet after, firmly hold absorption pure iron dish 61 and be connected with output shaft by terminal pad, transmitted power, outage back magnetic discharges, and output gear 3 idle running make output gear 3 after the moment off-load, carry out the forward and backward operate as normal again, the mechanical breakdown of output gear premature wear and broken teeth is solved.
Below in conjunction with drawings and Examples the utility model is further described.
