Abstract
The utility model discloses a three-dimensional adjustable type screw nut seat for medium-size and small-size numerical control machines. The utility model is especially used for a connection part of a screw rod. The utility model is characterized in that the screw nut seat 1 is installed on a screw nut of the screw rod, the upper end of the screw nut seat 1 is provided with a positioning groove, a positioning key 3 and a positioning pin 4 are installed in the positioning groove, the side surface at the upper end of the screw nut seat 1 is provided with two adjusting screw nails 8, the screw rod shaft is positioned in an axial direction through a slide plate 6, and the upper end surface of the screw nut seat 1 is provided with four adjusting screw nails 5. The utility model has the advantages that the utility model simplifies the processing and the assembly technique, improvers the processing precision, ensures the processing quality, reduce the labour intensity, etc.
Description
The utility model belongs to the main parts size that machine industry is used for machining apparatus, and exactly, the utility model is a kind of adjustable nut seat of the three-dimensional coordinate that is exclusively used in the leading screw joint that is used on the medium and small numerical control machine tool.
At present, China produces the producer of numerically controlled lathe in medium and small numerical control machine tool, and to the aligning aspect of ball-screw nut seat, very major part still adopts match grinding backing plate or direct set screw nut seat, the way of coming match grinding leading screw two supports frame.These ways make processing technology to a great extent and assemble complicated.For example: nut seat end face problem, if adopt when joining pad, its height dimension error and planeness, and with the parallelism on slide plate (or saddle) mating face etc., be difficult to guarantee that the leading screw center is parallel with the nut center, thereby cause the leading screw real work on curve, severe patient can produce two ends strength phenomenon, have influence on the working life of leading screw, precision is damaged.
The purpose of this utility model, be exactly according to the defective in the problems referred to above, for people provide a kind of new-type design, it is the adjustable nut seat of three-dimensional coordinate, this nut seat emphasis has solved under the feed screw nut free state, can make its center adjust to the optimum state with the leading screw center, can be complementary on the car three-dimensional coordinate, thereby make error of centralization reduce to minimum processing technology and assembly technology are simplified.
The utility model is by nut seat 1, leading screw 2, positioning key 3, locating stud 4 is adjusted screw 5, slide plate (or collet) 6, Cock screw 7 is adjusted screw 8 and is formed, and nut seat 1 is installed on the nut of leading screw, the upper end of nut seat 1 has a location poor, installing and locating key 3 during the location is poor, and location Xiao 4, upper side at nut seat 1 has two to adjust screw 8, by 6 pairs of leading screw axially locating of slide plate, there are four to adjust screw 5 in the upper-end surface of nut seat 1, carry out the height location by 6 pairs of screw mandrels of slide plate.
After the utility model is realized, can be widely used in the medium and small numerical control machine tool, compared with the prior art this technology has following advantage: processing, assembly technology are oversimplified 2. improved machining accuracy, eliminated curvilinear motion, guaranteed that 3. quality of processing makes the adjustment job simplification, has reduced labor intensity.
Below in conjunction with embodiment the utility model is further specified:
Fig. 1 is the main TV structure schematic representation to model utility.
Fig. 2 is the plan structure schematic representation to model utility.
Among the figure: the 1-nut seat, the 2-leading screw, the 3-positioning key, the 4-locating stud, 5-adjusts screw, the 6-slide plate, the 7-Cock screw, 8-adjusts screw.
Embodiment: nut seat is cylinder iron cast size length 100, and is wide by 80, high by 70, the through hole of middle processing φ=42, and key poor size in upper end is wide by 16, and dark 10 is long by 80,6 on adjustment spiral shell, the commercially available standard piece of M8; Positioning key is with No. 45 steels, size: 80 * 16 * 10 1, locating stud is with No. 45 steel car systems, and size φ 12 * 30.After making each component by above-mentioned requirements, press Fig. 1, Fig. 2 and install and get final product through debugging.
This adjustable nut seat adjusting method is: earlier with leading screw two supports frame centering, and nut seat 1 packed on the feed screw nut, in the keyway of the nut seat upper end of then positioning key 3 and locating stud 4 being packed into successively, at last slide plate (or collet) 6 is packed into from top to bottom.Before adjusting nut seat 1 is moved to arbitrary end at leading screw two ends with nut, screw 5 (totally 4) is adjusted in turn makes it stressed evenly, make it nimbly and freely with the hand rotational lead screw simultaneously, screw Cock screw 7 (totally 2) then slightly, tightening adjustment screw 8 (totally 2) makes between positioning key 3 and locating stud 4 and the nut seat 1 and eliminates axial clearance more afterwards, last fastening Cock screw 7 is adjusted and is finished.The method of adjustment screw 8 has multiple, decides on nut seat 1 residing position.
Claims (1)
- The adjustable nut seat of a kind of three-dimensional coordinate, by nut seat (1), leading screw (2), positioning key (3), locating stud (4) is adjusted screw (5), (8), slide plate or collet (6), Cock screw (7) is formed; It is characterized in that: nut seat (1) is installed on the nut of leading screw, there is a locating slot upper end of nut seat (1), installing and locating key (3) and locating stud (4) in the locating slot, upper side at nut seat (1) has two to adjust screw (8), to the leading screw axially locating, there are four to adjust screw (5) by slide plate (6) in the upper-end surface of nut seat (1).
