Abstract
The utility model relates to a late-model drawing machine head which is composed of an I-shaped straight ruler, a non-disc type angle reading device, an angle vernier device, and an angle position locking device. Compared with a drawing machine head which is composed of an L-shaped straight ruler disc type angle reading device and is commonly used with the prior art for a drawing machine, the utility model has the advantages of smaller volume, convenient process for reading number, convenient operation and easy fabrication. The utility model also has the function for an angle vernier. The late-model drawing machine head is an effective device which can promote an existing drawing machine to improve performance.
Description
The utility model relates to a kind of plotting unit.
The head form that existing draught machine technology generally adopts is a kind of by " L " shape ruler, the indication of disc type angle, the mechanism that " L " shape ruler angle position lock release device and control crank are formed.Its deficiency is, the angle indicating device of tray type structure is owing to the clear indication that will obtain the line drawing ruler angle, and the interval of adjacent angle groove can not be too small, so structure is difficult to miniaturization, and because the setting-out of " L " type of employing ruler, so the bulk that whole head occupies on chart board is bigger.In addition, the transfer of the angle of " L " type ruler is fully by control crank control, and the fine motion that lacks angle is regulated, and when requiring than the accurate Drawing angle line, general need the adjustment through several times just can reach, so the raising of drawing efficiency is had a direct impact like this.Other deficiency shows that also structure is complicated, and manufacture craft requires high.
The purpose of this utility model is that a kind of novel draught machine head will be provided, and overcoming the deficiency of existing draught machine head, and makes it have the better performance of manipulating.
The technical solution of the utility model is: line drawing ruler is got the single chi form of " one " font; Its end is connecting and the vertical rotating shaft of chi body self, rotating shaft is passed an axis hole that is molded on the base plate and is connected with main driving wheel, main driving wheel is got in touch by driving-belt or with the direct kind of drive and time drive, inferior drive is got in touch with one group of gear that can change transmission direction again, and the angular displacement of line drawing ruler is passed to angle indicating device; The angle indicating device device is on base plate, by the angle index endless belt that is sleeved on driving wheel and the driven pulley, topped Transparent Parts on the angle index endless belt be configured to, driving wheel and driven pulley are rack-mount, the rotation of driving wheel is taken from the aforementioned gear train that changes transmission direction by the axle that draws that is connected with driving wheel; The extension of aforementioned rotating shaft installs the turn-knob or the handle of line drawing ruler angle transfer, another turn-knob with inferior drive co-axial arrangement; Be the semi-surrounding structure and cladding brake band on the main driving wheel outer rim, an end of brake band is fixing on base plate, and the other end is subjected to the tractive of a spring, and gets in touch with a lever, moves lever, can loose brake band.
In technique scheme,, can do whole head very for a short time because the utility model has been taked the belt structure of non-disc type and single chi structure of line drawing ruler to angle index and reading mode; And can realize control by two turn-knobs associated (or handle) with it to the control that setting-out size angular misalignment changes, thus can realize angle position fine setting to line drawing ruler, so use the utility model can realize the more drawing of precise and high efficiency.
Below in conjunction with the embodiment accompanying drawing in detail the utility model is described in detail
At first accompanying drawing is described
Fig. 1. represent cut-away view of the present utility model
Fig. 2. represent external structure of the present utility model
Referring to accompanying drawing, line drawing ruler (10) one ends link by plate (11) and rotating shaft (9), rotating shaft (9) is vertically passed an axis hole that is arranged on the base plate (1) and is connected with main driving wheel (8), main driving wheel (8) links by driving-belt (13) and time drive (6), the bevel gear set (3) that can change transmission direction through time drive (6) and links, the angular displacement of line drawing ruler can be passed to angle indicating device, angle indicating device is arranged on the base plate (1) by support (17), one end device of support (17) driving wheel (14), the other end installs driven pulley (18), the rotation of driving wheel (14) is by taking from bevel gear set (3) with the axle (19) that draws of self coenosarc, the scale band (16) that is provided with angle index is loop-like, be sleeved on driving wheel (14) and the driven pulley (17), go up the topped Transparent Parts (15) that has at scale band (16), Transparent Parts (15) is provided with angle vernier indication groove with the contacted surface of scale band (10), constitute the angle value readings device, Transparent Parts (15) device is on support, and the angle value of residing angle position of line drawing ruler (10) or rotation process can directly be read from Transparent Parts (15); Spud pile (4) also is being set on base plate (1), (12), one end of brake band (7) is enclosed within the stake (12), the other end and spring (5), lever (2) connects, the other end of spring (5) is connected with stake (4), brake band is semi-surrounding structure cladding in the outer rim of main driving wheel (8) or the cladding outside in the driving-belt that is enclosed within main driving wheel (8) (13), the tractive that brake band (13) is subjected to spring (5) wraps tightly on main driving wheel (8), can realize locking position to line drawing ruler (10), move lever (2), can loose brake band (13), can discharge main driving wheel (8), line drawing ruler this moment (10) is translation-angle arbitrarily; As Fig. 1. shown in, be cut-away view of the present utility model.
Rotating shaft (9) extension passes case (22) and is connected with turn-knob (21), by the angular transformation of turn-knob (21) direct manipulation line drawing ruler (10); Wheel shaft from the inferior drive (6) extends the part that passes case (22) and is connecting turn-knob (20), the impeller diameter ratio of getting time drive (6) wheel footpath and main driving wheel (8) is less than 1 o'clock, regulates turn-knob (20) and can realize angle position fine setting to line drawing ruler (10).
