Abstract

The utility model discloses a shaft lifting device for moving guiding rail and fixing the slide block of rolling guide, comprises framework, guiding rail and slide block of rolling guide, the slide block is fastened on the framework, the guiding rail and movable part are fixed each other. The utility model adopt the structure of fixing guiding rail and movable parts through fixed slide block, use the guiding rail to strengthen the movable parts, thus the rigidity of middle position is increased to guarantee the smooth motion, precision and convenient installation.

Description

A kind of slide block with rolling guide is fixed and guide rail moves the device of realizing the axle lifting

Technical field

The utility model belongs to the mechanical motion mechanism technical field, relates to a kind of device of realizing a lifting, is specifically related to a kind of slide block with rolling guide and fixedly makes guide rail move the device of realizing a lifting.

Background technique

Rolling guide is the device that is used for realizing two parts relative displacements.The structure of existing rolling guide is that guide rail is fixed on the frame, and moving member is fixed on the slide block, adopts one or two rolling guide parallel arranged, does elevating movement by the motion drive moving member of slide block.And to realize the lifting of moving member with the rolling guide of this structure, just slide block must be placed on the bottom of moving member, so, the center of gravity of moving member is just at immovable point---above the slide block, will cause the moving member lifting not steady, influence kinematic accuracy, it is also very difficult to install and fix screw in addition.

Summary of the invention

The purpose of this utility model is to provide a kind of slide block with rolling guide to fix and guide rail moves the device of realizing the axle lifting, has solved existing rolling guide and has made the jiggly problem of moving member lifting.

The technological scheme that the utility model adopted is, a kind of slide block with rolling guide is fixed and guide rail moves the device of realizing the axle lifting, comprises frame, guide rail and along the slide block of guide rail movement, slide block is fixed on the frame, and guide rail and moving member fix.

Characteristics of the present utility model also are,

Slide block and guide rail are provided with two groups, are symmetrical in the both sides of moving member.

The utility model adopts fixedly slide block and with guide rail and the fixing structure of moving member, with guide rail moving part is played reinforcement effect, has increased the rigidity of intermediate portion, and it is steady that it is moved, and kinematic accuracy is protected, and has characteristics easy for installation.

Description of drawings

Fig. 1 is the structural representation of prior art rolling guide;

Fig. 2 is an embodiment of the utility model structure;

Fig. 3 is another embodiment of the utility model structure.

Among the figure, 1. frame, 2. guide rail, 3. slide block, 4. moving member.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

What Fig. 1 showed is the structure of existing rolling guide.As can be seen from the figure, two guide rails 2 are fixedly mounted on the frame 1 side by side, and moving member 4 places between two guide rails, and slide block 3 is installed on the bottom of moving member 4, along with slide block 3 moves along guide rail 2, drive moving member 4 and do axial motion.The unreasonable of this structure is that the top of moving member 4 is not supported, and must be bumpy motion, influences kinematic accuracy.

The utility model is realized the device of axle lifting, comprises frame 1, guide rail 2 and the slide block 3 that moves along guide rail 2, and slide block 3 is fixed on the frame 1, and guide rail 2 fixes with moving member 4, and slide block 3 can be provided with two groups with guide rail 2, and symmetry is installed on the both sides of moving member 4.

Fig. 2, Fig. 3 show moving member 4 respectively when cylindrical or plate shaped, and two groups of slide blocks 3 and guide rail 2 symmetries are installed on the form of moving member 4 both sides.

During installation, guide rail 2 can be assemblied in the intermediate portion of moving member 4 earlier, put into frame 1 then, with bolt slide block 3 is fixed on the frame 1 from the outside again.

The structure that the utility model adopts guide rail to reinforce moving member, make the center of gravity of moving member, in half stroke all the time below slide block, in second half stroke, both gradually change by distance value, last just can reach maximum value when upper limit (UL) point---1/2 of total travel, because the increase of moving part intermediate portion rigidity makes it reach the purpose stably of moving.

Claims

1. the slide block with rolling guide is fixed and guide rail moves the device of realizing the axle lifting, comprise frame (1), guide rail (2) and the slide block (3) that moves along guide rail (2), it is characterized in that described slide block (3) is fixed on the frame (1), described guide rail (2) fixes with moving member (4).

2. according to the described device of claim 1, it is characterized in that described slide block (3) is provided with two groups with guide rail (2), is symmetrical in the both sides of moving member (4).
