Abstract
The invention discloses a lead screw drive device for a boring lathe. The lead screw drive device for the boring lathe comprises a ballscrew, a support used for fixing the ballscrew, a servo motor arranged at one side of the support, a coupling connected with the servo motor and the ballscrew, a lead screw nut seat fixed on the ballscrew and a lead screw nut seat connection body. The lead screw drive device for the boring lathe is characterized by further comprising a plurality of adjusting screws which are fixed on the lead screw nut seat connection body. The lead screw drive device for the boring lathe has the advantages that through the arrangement of the plurality of adjusting screws, not only is the over-locating phenomenon of a lead screw transmission portion eliminated, structure is optimized, but also adjustment is more simple and convenient, moreover, the precision of lead screw transmission portion and the stationarity of a sliding table of the boring lathe in machining are improved, and therefore the machining precision of a hole is improved.
Description
Technical field
The present invention relates to a kind of lead screw gear, especially a kind of boring machine lead screw gear.
Background technology
at present in prior art feed screw nut seat connector with after the supporting at ball-screw two ends adds the feed screw nut seat and the boring machine slide unit is fixedly connected with, be actually the location, the assembly precision of the machining accuracy of inevitable requirement part and boring machine is all quite high like this, required precision when satisfying lead screw transmission, but, the practical operation inconvenience of getting up also is difficult to grasp, especially when feed screw nut seat center is high, will be through repeated disassembled and assembled many times, waste time and energy and do not say, the transmission of spindle arrangement is uncertain smooth and easy often, have some setbacks and just easily produce vibration, finally cause the not steady of boring machine slide unit when operation, thereby affect the precision index in hole, this has restricted labor productivity to a certain extent.
Summary of the invention
The present invention seeks to: provide a kind of simple in structure, conveniently detect and adjust and can improve the precision of lead screw transmission and the boring machine lead screw gear that the boring machine slide unit is processed stationarity when moving.
Technical scheme of the present invention is: a kind of boring machine lead screw gear, comprise ball-screw, be used for the fixedly bearing of ball-screw, be positioned at the servomotor of bearing one side, with the shaft coupling that servomotor is connected with ball-screw, be fixed in feed screw nut seat and feed screw nut seat connector on ball screw, it is characterized in that, also comprise several adjustment screws, described adjustment screw is fixed on described feed screw nut seat connector.
Preferably, the head of described adjustment screw is spherical head.
Preferably, the number of described adjustment screw is 3, and is uniformly distributed on the circumference of feed screw nut seat connector.
the present invention has evenly installed 3 adjustment screws that head is spherical in shape on feed screw nut seat connector circumference, each adjustment screw is a contact with being connected of boring machine slide unit like this, and can determine a plane, the perpendicularity of this plane and feed screw nut seat connector and the center height of ball-screw all utilize these 3 adjustment screws to adjust to guarantee, by detecting and adjusting, can make lead screw transmission reach an optimum state, just the screw of circumference uniform distribution can be tightened gently at last, preferably use torque wrench, according to the difference of adjusting screw nominal thread size, select equally large moment of torsion, make its all stressed getting final product just.This ball-screw be actually active link being connected of boring machine slide unit.So not only eliminated the positioning phenomenon of crossing of lead screw transmission part, optimized structure, adjust simultaneously more simple and convenient, the more important thing is, the stationarity when having improved the precision of lead screw transmission and boring machine slide unit processing operation, thus improved the machining accuracy in hole.
Advantage of the present invention is: adjust screw by increasing by 3, not only eliminated the positioning phenomenon of crossing of lead screw transmission part, optimized structure, adjust simultaneously more simple and convenient, the more important thing is, stationarity when having improved the precision of lead screw transmission and boring machine slide unit processing operation, thus the machining accuracy in hole improved.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is lead screw transmission part schematic diagram of the present invention;
Wherein: 1 ball-screw, 2 bearings, 3 servomotors, 4 shaft couplings, 5 feed screw nut seats, 6 feed screw nut seat connectors, 7 adjust screw, 8 boring machine slide units.
The specific embodiment
embodiment: with reference to shown in Figure 1, a kind of boring machine lead screw gear, comprise ball-screw 1, be used for the fixedly bearing 2 of ball-screw 1, be positioned at the servomotor 3 of bearing 2 one sides, is connected the shaft coupling 4 that is connected with ball-screw with servomotor 3, be fixed in the feed screw nut seat 5 on ball screw 1, feed screw nut seat connector 6 and 3 adjustment screws 7, this feed screw nut seat connector 6 is fixedly connected with boring machine slide unit 8, adjusting screw 7 is fixed on feed screw nut seat connector 6, the head of this adjustment screw 7 is spherical head, and the number of adjusting screw 7 is 3 and is uniformly distributed on the circumference of feed screw nut seat connector 6.
the present invention has evenly installed 3 adjustment screws 7 that head is spherical in shape on feed screw nut seat connector 6 circumference, each adjustment screw 7 is a contact with being connected of boring machine slide unit 8 like this, and can determine a plane, the perpendicularity of this plane and feed screw nut seat connector 6 and the center height of ball-screw 1 all utilize these 3 adjustment screws 7 to adjust to guarantee, by detecting and adjusting, can make lead screw transmission reach an optimum state, just the screw of circumference uniform distribution can be tightened gently at last, preferably use torque wrench, according to the difference of adjusting screw 7 nominal thread size, select equally large moment of torsion, make its all stressed getting final product just.This ball-screw 1 be actually flexible connection being connected of boring machine slide unit 8, so not only eliminated the positioning phenomenon of crossing of lead screw transmission part, optimized structure, adjust simultaneously more simple and convenient, the more important thing is, improve the precision of lead screw transmission and the stationarity that boring machine slide unit 8 is processed when moving, thereby improved the machining accuracy in hole.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.All modifications that the Spirit Essence of main technical schemes is done according to the present invention are within all should being encompassed in protection scope of the present invention.
