Abstract
The involute principle shows that the involute length of the involute and the inner circumference length of the involute are equal, and the change of the diameter of an inner circle decides the size of the involute. In order to meet the requirement of dividing the involutes with different sizes, the diameter of the inner circle must be changed randomly by methods. Therefore, a central post 2, upper and lower racks 3 and 12, a middle rack 10 and a fulcrum bar 5 are provided to form the variable diameter of the inner circle; and a magnet 11 arranged on the middle rack 10, a suction gauge bar 17, and a screw sleeve 9, a penholder 7, a nut 8, a handle 6, a pen cap 13, a tightening block 14 and a pencil core 15 which are arranged at the end part of the middle rack 10 form the whole stepless involute planning.
Description
Technical field
Instrument class or drawing instrument class.
Background technology
In the construction of machining or when drawing, often run into involute, be very bothersome with standardized involute of commonsense method, can there be this type of instrument now again, I work out a kind of " stepless involute planning " for this reason, can once be divided into involute with it.
Summary of the invention
It is that the inner periphery length of involute is that principle is invented with the length of gradually opening of involute.
Description of drawings
Accompanying drawing is stepless involute planning side sectional view when opening.
The specific embodiment
If a newel (2) is divided into two sections to newel from the centre, the epimere external diameter processes left hand thread, and the hypomere external diameter processes right-handed thread, and the lower end screws in and has in the base (16) of identical screw thread, and upper-end inner diameter is processed with screw thread, so that screw in handrail (1); Establish two hangers (3), (12) again, upper hanger (3) internal diameter processes left hand thread, so that it is equipped with the epimere of newel, (this number is unfixing to be provided with 12 around the external diameter of hanger, can adjust as required) hangers, evenly distributed, in the middle of the hangers porose (4), each hangers can be hung a pole (5), wears with screw (4); Following hanger and upper hanger are basic identical, just internal diameter whorl is dextrorotation, so that it is equipped mutually with the right-handed thread of newel lower end, when screwing in this hanger, note identical to right-and-left threaded marginal distance with upper hanger, reach symmetry, pole (5) is all identical with upper hanger with screw (4); The assembling of middle frame (10): under the symmetrical prerequisite of hanger about the maintenance, at first find out two poles up and down on same vertical line on the hanger about having hung over, middle frame (10) and its are pacified the jail with screw (4) by figure, other carries out according to the order of sequence, after 12 middle frames have all been pacified, set up manufactured magnet piece (11) again, the newel lower end screws in the base (16), the upper end screws in handrail (1), and this newel assembling finishes.Assemble gauge bar (17) and penholder (7) below again: it is rectangular strip shape body that gauge bar (17) application steel manufactures the cross section, and purpose is to attract mutually with magnet piece (11).Be assembling sequence below: silk braid (9) and penholder (17) can be processed into one, penholder (7) is screwed in the silk braid (9), refill, screw in handle (6) by cap nut (8), the cap for brush (13), stretching piece (14) and pencil-lead (15) are equipped with in the penholder lower end, and all assembling finishes now.
Use: one holds pole, and rotating handrail just can be adjusted circular diameter in the involute of being made up of 12 middle frames on the other hand.After mixing up, base is fallen into the center of involute; Gauge bar is picked up, and with the starting point that nib is aimed at involute, gauge bar is attached on the magnet piece of middle frame, can stand firm; At this moment can pin the newel handrail on the other hand, another holds the penholder handle, allows gauge bar forward on another piece magnet piece from this part magnet piece, continues always, and nib just can mark involute.If want to draw reverse involute, can transfer turnback to gauge bar, be attached to again on the magnet piece, just can draw reverse involute.
