Abstract
The utility model discloses a kind of helical screw rotary spanner, belongs to screwing tool field, particularly relates to the wind big gun that dismounting automobile tire steel plate screw is used.The wind big gun instrument of current application, structure is more complicated, gravity is comparatively large, air pressure is required to higher and pressure-air consumption, loss is comparatively large, noise is larger when using.The utility model helical screw rotary spanner, the screw rod being rotated through one group of screw rotarily drives, screw rod lower end is positioned at wrench body, fixedly moved up and down by one group of pressure bearing, prevented screw mandrel from moving in screw mandrel tangential direction by one group of ball bearing, upper lower ejector lever rotary power promotes screw nut from one group of identical cylinder and moves up and down, cylinder and wrench body are fixed, so Telescopic-cylinder process nut can not rotate, can only move up and down with pull bar, drive screw rod rotates, when pull bar rotates, pull bar termination installs casing head, just can carry out the work of rotating nut.
Description
Technical field
The invention belongs to screwing tool field, particularly relate to the wind big gun that dismounting automobile tire steel plate screw is used.
Background technology
The wind big gun instrument of current application, structure is more complicated, gravity is comparatively large, air pressure is required to higher and pressure-air consumption, loss is comparatively large, noise is larger when using.
Summary of the invention
Helical screw rotary spanner of the present invention, the screw rod being rotated through one group of screw rotarily drives, screw rod lower end is positioned at wrench body, fixedly moved up and down by one group of pressure bearing, prevented screw mandrel from moving in screw mandrel tangential direction by one group of ball bearing, upper lower ejector lever rotary power promotes screw nut from one group of identical cylinder and moves up and down, cylinder and wrench body are fixed, so Telescopic-cylinder process nut can not rotate, can only move up and down with pull bar, drive screw rod rotates, when rotating shaft rotates, rotating shaft termination installs casing head, just can carry out the work of rotating nut.
Cylinder that the present invention adopts, also can adopt hydraulic cylinder, and under same volume, hydraulic cylinder more can increase the contractility of rotating shaft greatly, so under certain revolving force requires, hydraulic cylinder can make spanner reduce volume more.
Helical screw rotary spanner of the present invention, comprise rotating shaft (1), the ball bearing (10) of stable axis, wrench body (11), pinch bar (18), it is characterized in that spanner also comprises a set of ball screw screw mandrel, nut (9), two cylinders (6) and piston (5) thereof, pull bar (4), firm banking (8), the screw axial of described rotating shaft and ball screw screw mandrel connects together with one heart, feed screw nut (2) outside screw rod, screw rod lower end is positioned at the part of wrench body (11), there are upper and lower two ball bearings (10), also have two pressure bearings (7), be positioned at main body one firm banking (8) both sides up and down, described screw rod lower end also has a nut (9), it is following that nut is positioned at a pressure bearing, described feed screw nut (2), be fixedly connected with two air cylinder tie rods (4), two cylinder bottom are fixedly connected with wrench body.
The present invention two cylinder, size, structure are identical, and being connected with feed screw nut of air cylinder tie rod symmetry, cylinder comprise cylinder air inlet main pipeline (22), piston (5) upside have two length, the identical admission line of internal diameter (13), piston underside to have two length, the identical admission line of internal diameter (14), cylinder two group of branches admission line is communicated with magnetic valve (15), magnetic valve (15) energising, power-off two states respectively control cylinder pull bar are stretched, thus make spanner clockwise, left-hand circular rotates.
The electromagnetic valve switch of screw spanner is finally positioned near wrench body handle (18), with easy to use.
The present invention rotarily drives rotating nut by the screw rod of screw, there is the feature overcoming technology prejudice, compared with wind big gun general at present, the advantage having weight greatly to alleviate, use time greatly save pressure-air consumption, use time noise less, and have the advantage that can reduce required air pressure, and structure is simple, use birthday noodle long.
Accompanying drawing illustrates:
Fig. 1 is the air cylinder tie rod of screw rotary spanner structure diagram when stretching out
Fig. 2 is the air cylinder tie rod revolving leading screw rotary spanner air cylinder structure sketch when stretching out
Detailed description of the invention:
When screw mandrel spanner complete a upper rotary work static time, cylinder two pull bar (4) is the state of stretching out, spanner rotating shaft (1) upper end is installed required casing head, by moving electromagnetic valve (15) switch, cylinder (6) pull bar (4) is replied rapidly, because feed screw nut (2) is connected by two pull bars, can not rotate, feed screw nut moves down rapidly with pull bar, feed screw nut moves down simultaneously, pull bar rotates thereupon, again press moving electromagnetic valve, pull bar can be shot out again, pull bar rotates again, before and after pull bar, twice direction of rotation is always contrary, the direction needing to rotate is selected as required during use.
