Abstract

The utility model relates to a mechanical guide device which comprises a main guide wheel, a key, a convex shoulder stepped shaft, an end cover, a bearing, lateral guide wheels, a base, a pin shaft, a guide rail and a bracket. The guide rail is fixed on the base by a bolt, the main guide wheel is fixed on the convex shoulder stepped shaft by the key, a convex shoulder can ensure the axial positioning of a main guide wheel bearing and is supported by the guide rail, the two ends of the convex shoulder stepped shaft are supported by the bearing and are arranged on the bracket, the end cover which is fixed on the bracket by the bolt is used for sealing and axially fixing the bearing, the pin shaft is fixed with the bracket by a thread arranged at the upper end of the pin shaft, the two lateral guide wheels are supported by the bearing and are arranged on the pin shaft, and the bracket is fixed with mechanical equipment by the bolt. As the rolling wheel type lateral guide wheels are adopted, good position limiting is realized, and the linear motion of the mechanical equipment can be ensured; moreover, the lateral guide wheels roll at the two side faces of the guide rail in relation to the guide rail, so that the friction between the guide rail and rolling wheels is lessened, and the guide performance is good.

Description

A kind of mechanical guiding device

One, technical field

The utility model relates to a kind of mechanical guiding device, belongs to equipment manufacturing technology field.

Two, background technology

The mechanical guiding device field that in mechanical engineering, has a wide range of applications.In many places, people require the mechanical movement part to realize straight-line motion, and designing usually on the engineering has guide piece.If there is not guide piece, sideslip will take place in straight-line motion.Guide piece commonly used in existing engineering is used has: slider guide, plain bearing guiding, guide rail guiding, straight-line guidance.In the guiding of heavy mechanical equipment as adopt fixed type slider guide, mechanism can not normally move friction force between big guide piece of side force and guide rail increase in addition can occur stuck, and dismounting trouble; As adopt the floating slider guide piece, owing to there is the morpheme error of guide rail, make to be difficult to realize that its face contacts between floating slider and guide rail in the real work.Thereby cause mechanical equipment normally not move.Above guide piece as the guiding of light-duty machinery equipment, often can not satisfy the requirement of guiding mostly for heavy mechanical equipment.

Three, summary of the invention

The purpose of this utility model provides a kind of mechanical guiding device, adopts roller type side track adjusting wheel, realizes spacingly preferably, guarantees the straight-line motion of mechanical equipment; The side track adjusting wheel is rolled with respect to guide rail in the guide rail two sides, has reduced the friction between guide rail and roller, and steering capability is good, is applied to the mechanical guide in the heavy mechanical equipment.

Fig. 1 is a composition constructional drawing of the present utility model, and it comprises main track adjusting wheel 1, key 2, convex shoulder stepped shaft 3, end cap 4, bearing 5, side track adjusting wheel 6, pedestal 7, bearing pin 8, guide rail 9, support 10 compositions.

Guide rail 9 is fixed by bolts on the pedestal 7, main track adjusting wheel 1 is fixed on the convex shoulder stepped shaft 3 by key 2, convex shoulder is guaranteed leading axial location to wheel bearing, and by guide rail 9 supports, axle 3 two ends are supported and are installed on the support 10 with bearing 5, end cap 4 is fixed by bolts on the support 10, sealing and axial restraint bearing 5, bearing pin 8 is fixing by the screw thread and the support 10 of its upper end, two side track adjusting wheels 6 are by bearings and be installed on the bearing pin 8, and contact with two sides of guide rail 9, support 10 usefulness bolts and mechanical equipment are fixed.

During work, guide piece under the drive of mechanical equipment, main track adjusting wheel and guide rail surface closed contact and moving linearly thereon; The both sides track adjusting wheel contacts with the two sides of guide rail respectively, and rolls.Like this, main track adjusting wheel and two side track adjusting wheels just retrained mechanical equipment on horizontal surface cross travel and be rotatablely moving of axis with the guide rail, guaranteed the straight-line motion of mechanical equipment along guide rail.

Compare the advantage that has with known technology

1) adopts roller type side track adjusting wheel, can realize spacingly preferably, prevented that mechanical equipment from rotating around track, guaranteed the straight-line motion of mechanical equipment;

2) the side track adjusting wheel is rolled with respect to guide rail in the guide rail two sides, has reduced the friction between guide rail and roller;

3) can realize the installation and the application of level and vertical both direction;

Four, description of drawings

Accompanying drawing is a structural representation of the present utility model, among the figure, and the 1st, main track adjusting wheel, the 2nd, key, the 3rd, convex shoulder stepped shaft, the 4th, end cap, the 5th, bearing, the 6th, side track adjusting wheel, the 7th, pedestal, the 8th, bearing pin, the 9th, guide rail, the 10th, support.

Five, the specific embodiment

Mechanical guiding device as shown in Figure 1, it comprises main track adjusting wheel 1, key 2, convex shoulder stepped shaft 3, end cap 4, bearing 5, side track adjusting wheel 6, pedestal 7, bearing pin 8, guide rail 9, support 10.Guide rail is fixed by bolts on the base 7, main track adjusting wheel 1 is fixed on the convex shoulder stepped shaft 3 by key 2, convex shoulder is guaranteed leading axial location to wheel bearing, and by guide rail 9 supports, axle 3 two ends are supported and are installed on the support 10 with bearing 5, end cap 4 is fixed by bolts on the support 10, it is used for sealing and axial restraint bearing 5, bearing pin 8 is fixing by the screw thread and the support 10 of its upper end, two side track adjusting wheels 6 are by bearings and be installed on the bearing pin 8, and contact with two sides of guide rail 9, support 10 usefulness bolts and mechanical equipment are fixed.

This mechanical guiding device not only can level be installed, and also can vertically install.During installation, adopt one group, two groups or three groups of above mechanical guiding devices as required.If on large-scale vertical cylinder face, install, should be uniform in a circumferential direction, could well realize mechanical equipment straight-line motion in vertical direction.
