Abstract

The invention discloses a movable carrying table which comprises a carrying table, a moving box and a polished rod, wherein three bearings are arranged in the moving box to form a space through which the polished rod can penetrate; the outer side walls of the first bearing and the second bearing are in point contact with the polished rod; and the third bearing is in moving compaction linear contact with the polished rod. When a locking hand shank performs locking, the third bearing in the moving box compacts the polished rod and contacts the polished rod together with the first bearing and the second bearing; the three bearings are in threaded transmission with the polished rod; the polished rod and the moving box rotate at a certain relatively low speed; the moving box drives the carrying table to realize micro adjustment, so that movable carrying table is suitable for precisely adjusting a relatively short distance between an object and a set position; when the locking hand shank performs release, the third bearing is separated from the polished rod, and the polished rod is only stressed by friction of the first bearing and the second bearing, so that the polished rod and the moving box connected with the carrying table can quickly move relatively; and therefore, the carrying table can be adjusted to move quickly and is suitable for relatively long distance between the object and a set position so as to save the adjustment time.

Description

A kind of movably microscope carrier

Technical field

The present invention relates to a kind of movably microscope carrier, belong to field of mechanical technique.

Background technology

Microscope carrier is to be used for the platform of loaded object, to object process, when measuring, moving object normally realized through moving microscope carrier in the position that often needs moving article to set.General type of drive all makes microscope carrier move with a constant speed, can move with mode at a slow speed and fast if will realize microscope carrier, relies on complicated transmission, adjusting device to realize through needs, makes complex structure, cost higher.

Summary of the invention

The specific 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, movably microscope carrier of the present invention comprises, microscope carrier 10, the mobile box 1 that is fixedly connected on microscope carrier 10 sides or bottom surface, polished rod 2.To move the side that box is arranged on microscope carrier 10 in the present embodiment.Polished rod 2 runs through mobile 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 or fine setting motion state.Thereby, by connected microscope carrier 10 motions of the mobile drive of moving box 1, make the microscope carrier 10 can rapid movement or fine setting motion, carry out fast moving or fine setting motion so that regulate the workpiece that is positioned on the microscope carrier 10, realize it is moved to desired location accurately.

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 on and move in the fixed head 11 fixing in the box; 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 CONTACT WITH FRICTION 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 to primary importance, set lever 7 drives double-screw bolts 5 through briquetting 4 and rotates together along axis rotation lock handle 7, 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 the fine setting motion state; Three bearing Z1, Z2, Z3 acting in conjunction are with polished rod 2 clampings wherein; At this moment, can't stir mobile box 1 with hand, can only be through rotating handwheel 3; Make rotatablely moving of polished rod 2 regulate and make moving of polished rod 2 and mobile box 1, drive microscope carrier 10 fine motions thereby realize moving box 1 by being equivalent to the screw thread transmission.

During towards relative direction rotation lock handle 7; Set lever 7 drives double-screw bolts 5 through briquetting 4 and rotate together, and 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 of mobile 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, and fast moving that can be relative between mobile box 1 and the polished rod 2; Only with hand is stirred mobile box 1 makes it move axially along polished rod 2, can make to move between box 1 and the polished rod 2 to 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.
