Description

Technical Field

[0001] The utility model belongs to the technical field of linear guide rails, and in particular relates to a linear guide rail with a precision adjustment function. Background Art

[0002] With the development of science and technology, equipment is becoming more and more advanced. People now have higher and higher requirements for the accuracy of equipment position, and the use of linear guides is increasing. When using linear guides, a set of linear guides is usually used, with two linear guides as a set.

[0003] Under normal use, the linear guide rail only plays a guiding role, and the force borne by the slide rails on both sides is not large. However, considering the installation accuracy of the linear guide rail, the track length, and the rigidity of the frame, the transported object will have a certain degree of relative position offset, affecting the use effect. Taking into account the structural characteristics of the linear guide rail, when the slider moves along the slide rail, there will be a lateral offset phenomenon of squeezing on one side of the linear guide rail and stretching on the other side, and then over-positioning will occur, which puts very high requirements on the mechanism and installation. In response to the above situation, there is a patent document in the prior art for a linear guide rail with a precision adjustment function, such as the patent number CN202120948775.7 published by the State Intellectual Property Office. It includes a bearing seat, a guide rail, a slider, a second wheel frame, a guide wheel, a pressure plate and a screw, etc. The guide wheel and other equipment set up in the slider are used to share the pressure on the slider, thereby avoiding the slider from being over-pressed. In the event of a jam, although this design can, to a certain extent, achieve convenient adjustment of the accuracy of the linear guide rail during operation, there are still certain disadvantages in actual use: on the one hand, the structural composition of the various components installed in the slider is relatively cumbersome and complex, which seriously affects the installation convenience of the linear guide rail equipment and limits the working process; on the other hand, the load-bearing effect of the slider is significantly reduced, and the operation process after connecting the workpiece will affect its load-bearing effect; even if the pressure can be shared, the establishment of multiple guide wheels will increase the friction of the linear guide rail during operation, and the smoothness of the slider's operation is limited, the use effect is poor, and it is difficult to meet the use requirements.

The adaptive adjustment mechanism 8 includes a vertical rod 81, a mounting plate 82 is provided on the outer side of the vertical rod 81, a rotating shaft 83 is provided between the two mounting plates 82, a sleeve 84 is provided on the outer side of the rotating shaft 83, a support plate 85 is provided on the outer side of the sleeve 84, an adapter wheel 86 is provided on the end of the support plate 85, a limiting ring 87 is provided on the outer side of the support plate 85 close to the sleeve 84, and a torsion spring 88 is provided on the outer side of the sleeve 84, one end of which is buckled with the mounting plate 82.

The geometric center of the plate is arranged in an S shape, which can not only realize the transmission of driving power, but also limit the position of the slider 5 to a certain extent to ensure smooth operation. It is specifically described as follows: when driving the slider 5, controlling the operation of the driving motor 71 can drive the driving wheel 72 to rotate, and drive the driven wheel 73 to rotate under the action of the synchronous belt 76, and act on the auxiliary wheel 74, so that the connecting plate and the slider 5 can be driven to move relative to the slide rail 4 to meet the use requirements.
