Embodiment 1

[0019] Such as figure 1 , figure 2 As mentioned above, in this embodiment, a static pressure unloading guide rail that is easy to adjust tightness includes a main guide rail 1, an auxiliary guide rail 2 installed on the main guide rail 1 and used for bearing force, and cooperatingly installed on the main guide rail 1 and the auxiliary guide rail 2 The slider 3 on the slider 3 is provided with a through hole 4 at the corresponding position, and the through hole 4 is equipped with a pressing part, and also includes an adjustment part 10 installed on the end face of the pressing part and used to adjust the tightness of the pressing part. .

[0020] In actual working conditions, due to the load-bearing effect of the auxiliary guide rail 2 and the pressing part, it can share part of the load on the main guide rail 1, so as to improve the load condition of the main guide rail 1, improve its wear resistance and stability of low-speed motion , and an adjusting part 10 is set on the...

Embodiment 2

[0022] This embodiment further limits the above-mentioned embodiments. In this embodiment, if image 3 As shown, the above-mentioned pressing part includes an adjusting screw 9, an elastic body 8 installed on the adjusting screw 9, a piston pin 6 installed on the free end of the elastic body 8, a rotating shaft 5 installed on the piston pin 6, and a joint through the rotating shaft 5 The rolling body 7 installed on the piston pin 6 , the adjusting part 10 is installed on the end face of the adjusting screw 9 .

[0023] The user can realize the adjustment of the movement tightness of the slider 3 by adjusting the adjustment part 10 , which is simple and convenient to operate and highly practical.

[0024] When in use, since the elastic body 8 itself has an elastic force in the axial direction, under the joint action of the adjustment screw 9, the piston pin 6 and the rolling body 7, there is a pressing force in the elastic body 8. In a certain state, due to When the relative p...

Embodiment 3

[0026] This embodiment is further limited on the basis of the above-mentioned embodiments. In this embodiment, the above-mentioned rolling member 7 is a rolling bearing, the adjusting part 10 is an adjusting nut, and the elastic body 8 is a spring. Since the rolling bearing, the adjusting nut, and the spring all belong to Common items, and its price is cheap, so adopting the above structure can save manufacturing cost while achieving the purpose.

Abstract

The invention discloses a static pressure unloading guide rail convenient for tightness adjustment. The static pressure unloading guide rail comprises a main guide rail (1), an auxiliary guide rail (2) which is installed on the main guide rail (1) and is used for bearing a load, and a slide block (3) which fits to and is installed on the main guide rail (1) and the auxiliary guide rail (2), a through hole (4) is arranged on a corresponding position of the slide block (3), a compaction part fits to and is installed in the through hole (4), the static pressure unloading guide rail also comprises an adjustment part (10) which is installed on the end surface of the compaction part and is used for adjusting pressing tightness, the compaction part comprises an adjustment screw (9), an elastomer (8), a piston pin (6), a rotation shaft (5) and a roller (7) which fits to and is installed on the piston pin (6) through the rotation shaft (5), and the adjustment part (10) is installed on the end of the adjustment screw (9). The static pressure unloading guide rail improves loading conditions of the main guide rail (1), improves wear resistance and low-speed motion stability, is convenient for adjustment of slide block (3) motion tightness and has good practicality.

Description

technical field [0001] The invention relates to the field of guide devices, in particular to a static pressure unloading guide rail which is easy to adjust the tightness. Background technique [0002] A guide rail is a groove or ridge made of metal or other materials that can bear, fix, guide a moving device or equipment and reduce its friction. When the guide rail is in use, it often cooperates with the slider to move the working platform. Generally, the guide rail is a precision component, and the movement accuracy diameter of the slider on it affects the movement accuracy of the work platform. However, when the guide rail is under load, the load is distributed to the side wall of the guide rail, which will reduce its wear resistance and the stability of low-speed motion; Contents of the invention [0003] The object of the present invention is to provide a kind of static pressure unloading guide rail which is easy to adjust the tightness, adopt the form of setting auxi...
