Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Like Fig. 1, shown in Figure 2, the device of adjusting translational speed of the present invention comprises that one moves box 1 and runs through the polished rod 2 that moves 1 two relative sidewalls of box.One end end of polished rod 2 connects a handwheel 3, stirs when handwheel 3 rotates and can drive polished rod 2 around its axial rotation.Move box 1 and polished rod 2 moving axially of polished rod 2 relatively, and translational speed can be adjusted to rapid movement state and fine setting motion state.
Comprise three bearing Z in the mobile box 1, be respectively clutch shaft bearing Z1, the second bearing Z2 and the 3rd bearing Z3, each bearing all is connected through a bearing rod G and moves in the box 1.Clutch shaft bearing bar G1, the second bearing rod G2 all are arranged in the fixed head 11 that moves the box internal fixation; The 3rd bearing rod G3 is arranged on and moves in the box 1 interior mobilizable portable plate 12.Portable plate 12 is connected with fixed head 11 through a compression spring 8.
Polished rod 2 passes from the space of the lateral wall formation of three bearing Z1, Z2, Z3.And the equal rubbing contact of lateral wall of polished rod 2 and clutch shaft bearing Z1, the second bearing Z2, and the 3rd bearing Z3 movably compresses with polished rod 2 under the drive of the 3rd bearing rod G3 and contacts.
Three bearing Z1, Z2, Z3 be looped around polished rod 2 radially around; The 3rd bearing rod G3 is parallel with polished rod 2; Angle between the axis of clutch shaft bearing bar G1, the second bearing rod G2 and polished rod 2 axis is 2 degree; Like Fig. 3, shown in Figure 4, the 2 degree angles that form between the axis of clutch shaft bearing bar G1 and the axis of polished rod are inclined to one side to the top, and the clutch shaft bearing Z1 that is fixed on the clutch shaft bearing bar G1 is tilted.The 2 degree angles that form between the axis of the second bearing rod G2 and the axis of polished rod are inclined to one side for downwards, and the second bearing Z2 on the second bearing rod G2 is tilted.
The 3rd bearing rod G3 one side is provided with a briquetting 4, is fixedly connected a double-screw bolt 5 on the side of briquetting 4, and double-screw bolt 5 is arranged in the support plate 6, and cooperates with support plate 6 through screw thread, and the other end of double-screw bolt 5 withstands on the 3rd bearing rod G3.Be fixedly connected a set lever 7 on the another side of briquetting 4, set lever 7 is the L type, and an end is fixed on the briquetting 4, and the other end is to be suitable for the locking end that hand is stirred, and passes the wall that moves box 1 and places mobile box outside.
Set lever 7, double-screw bolt 5 are positioned on the axis; During along axis rotation lock handle 7, set lever 7 drives double-screw bolt 5 through briquetting 4 and rotates together, and double-screw bolt 5 moves towards the 3rd bearing rod G3 along support plate 6 through being threaded; The 3rd bearing Z3 is pressed on the polished rod 2; Make three bearing Z1, Z2, Z3 be 2 degree spiral angles, when handwheel 3 rotates, be equivalent to the screw thread transmission between three bearing Z1, Z2, Z3 and the polished rods 2 along axis direction; Make move between box 1 and the polished rod 2 can relative to slow moving, be in the fine setting motion state.
During towards relative direction rotation lock handle 7; Set lever 7 drives double-screw bolt 5 through briquetting 4 and rotates together; Double-screw bolt 5 is through being threaded along support plate 6 towards moving away from the direction of the 3rd bearing rod G3, the portable plate 12 at the 3rd bearing rod G3 place under the effect of back-moving spring 8 by bullet to the barrier that moves box 1 and get back to initial position, the 3rd bearing Z3 is separated with polished rod 2; The 3rd bearing Z3 no longer compresses polished rod 2; At this moment, move can be relative between box 1 and the polished rod 2 fast moving, only with hand is stirred and is moved box 1 and can make between mobile box 1 and the polished rod 2 and be in relative rapid movement state.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
