Abstract
The utility model relates to a vernier shifting gauge which is suitable for the marking tool of the metalworking machining parts in a factory. The utility model is composed of a leaf spring, a pivot shaft, a threaded rod, a leg rod, a main scale, a vernier and a drawing leg. The main scale and the drawing leg form an angle of a quarter; the utility model is provided with the vernier; the main scale is marked with the scale. The scribing dimension required by the work piece can be directly read out on the main scale. The utility model which is one of the ideal tools for the metalworking machining has the advantages of high precision, high work efficiency and convenient operation.
Description
The utility model relates to the scoring tool that a kind of factory metal working processing parts is used, and exactly is Vernier shifting gauge.
Current, what factory's metal working processing parts used plans, no rule is supporting, and scriber is not vertical with the section of part surface, and each line all will be measured required size with rule in addition, even the size of measuring is accurate, but because the section out of plumb of scriber and part, or factor such as scriber head wearing and tearing, so, the line that marks can not reach accuracy, influences quality and work efficiency.
The purpose of this utility model is that a kind of Vernier shifting gauge will be provided, and is intended to the size that can directly read required processing work from the vernier of planing, and simultaneously, the line size is accurately reliable, improves work efficiency.
The purpose of this utility model is achieved in that
A kind of Vernier shifting gauge, constitute by leaf spring, pivot, screw rod, leg bar, main scale, vernier, pin, slide block and stroke leg etc., it is characterized in that main scale (10) and slide block (15) are dynamically connected mouthful becomes horizontal translation pair, a right stroke leg (14) also is to be dynamically connected into vertical translation pair with slide block (15), and the glide direction of two translation pairs becomes 90 ° all the time; Main scale (10) is dynamically connected into revolute pair with right leg bar (19) by pin (16b), and vernier (9) is dynamically connected into revolute pair with left leg bar (4) by pin (16a); Two upper and lower parallel grooves are arranged on the vernier (9), main scale (10) inserts the horizontal translation pair of the interior formation of upper groove of vernier (9), the low groove that T shape slide block (8) inserts vernier (9) also forms horizontal translation pair, T shape slide block (8) lower end is drawn leg (20) with a left side and is dynamically connected into the translation pair, like this, a left side is drawn leg (20) and is formed 90 ° all the time with main scale (10); Left and right stroke of leg (20,14) is rotationally connected respectively by little pin (11a, 11b) with left and right leg bar (4,19),
The central point of pivot (2), with the central point of pin (16a, 16b) and little pin (11a, 11b) be two straight lines; Between little pin (11a, 11b) and the pin (16a, 16b) distance be between little pin (11a, 11b) and the pivot (2) distance 1/3～1/2.
It is to be rotationally connected that one end of pin (18) passes right leg bar (19), and the other end is to be threaded with screw rod (3), and fastening by screw (17); One end of pin (7) passes left leg bar (4) and also is rotationally connected, and screw rod (3) passes the other end of pin (7), and nut (6) and screw rod (3) form screw thread pair.Simultaneously, nut (6) and pin (7) form and rotate connection, screw (5) locking nut (6), it is not rotated.
When using, unclamp screw (5), turn nut (6), to adjust the distance of screw rod (3), simultaneously, main scale (10) is gone up at vernier (9) slided, when the scale on the aligning main scale of the zero line reading on the vernier (9) (10), just two scribers (12) are drawn in the size on the workpiece.
The utility model has the advantages that and vernier and main scale are housed on planing,, on vernier (9), can directly read that line accurately improves work efficiency, and is easy to use, one of real ideal tools of processing for metal working to the size of the required line of workpiece.
