Embodiment 1

[0036] A linear slide device such as figure 1 and figure 2 As shown, it includes: a first guide rail 100 , a second guide rail 200 and an ultrasonic vibrator 300 . The first guide rail 100 is provided with a first groove 110; the second guide rail 200 is provided with a first boss 210; the first boss 210 is accommodated in the first groove 110, and the first boss 210 can be opposite to the first groove 110 Sliding, lubricant is contained between the first boss 210 and the first groove 110 . The ultrasonic vibrator 300 is fixedly connected to the second guide rail 200 , and in this embodiment, the axial direction of the ultrasonic vibrator 300 is parallel to the sliding direction of the first boss 210 .

[0037] The vibration of the ultrasonic vibrator 300 drives the first boss 210 to vibrate at a high frequency and low amplitude. Through the same high-frequency vibration as the sliding direction, the lubricant moves rapidly along the sliding direction and enters the sliding...

Embodiment 2

[0048] The content of this embodiment is the same as that of Embodiment 1 and will not be repeated. The difference is that: image 3 As shown, the side of the second guide rail 200 away from the first boss 210 is provided with a second groove 220 , and the second groove 220 accommodates the ultrasonic vibrator 300 . The ultrasonic vibrator 300 is not outside, further freeing up space. The above settings can also be set in other embodiments, and the scope of protection of the present invention includes but is not limited to the situations enumerated in this embodiment.

Embodiment 3

[0050] The content of this embodiment is the same as that of Embodiment 2 and will not be repeated. The difference is that: Figure 4 As shown, the side of the second guide rail 200 away from the first boss 210 is provided with a second groove 220 , and the second groove 220 has an open port on one side. The setting of the open port reduces the processing difficulty, and the processing can be directly carried out from the open port, and also reduces the installation difficulty of the ultrasonic vibrator 300, and the ultrasonic vibrator 300 can be directly plugged and installed from the open port to the inside. The above settings can also be set in other embodiments, and the scope of protection of the present invention includes but is not limited to the situations enumerated in this embodiment.

Abstract

The invention provides a linear sliding device, and relates to the field of guide mechanisms. The linear sliding device comprises a first guide rail, wherein the first guide rail is provided with a first groove; a second guide rail which is provided with a first boss, wherein the first boss is contained in the first groove, the first boss can slide relative to the first groove, and lubricant is contained between the first boss and the first groove; an ultrasonic vibrator fixedly connected to the second guide rail, wherein the axis direction of the ultrasonic vibrator is parallel to the sliding direction of the first boss. The vibration of the ultrasonic vibrator drives the first boss to vibrate at high frequency and low amplitude, so that the lubricant is in a fluid state, and the creeping phenomenon at low speed is effectively eliminated. Meanwhile, the low-amplitude vibration of the ultrasonic vibrator does not influence the sliding stability and precision.

Description

technical field [0001] The invention relates to the field of guide mechanisms, and more specifically, to a linear sliding device. Background technique [0002] From the day of machine tool invention, guideway technology is one of its core technologies. The machining accuracy of the machine tool mainly depends on the guiding accuracy and motion stability of the guiding mechanism. [0003] The sliding guide rail is a guide rail in which the supporting part and the moving part are in direct contact. The advantages are simple structure, easy manufacture, and high contact stiffness. The disadvantage is that the friction resistance is large and the wear is fast; the difference between the dynamic and static friction coefficients is large. In order to reduce the frictional resistance of the sliding guide rail, lubricating oil is often injected into the sliding guide rail in the prior art. However, only when sliding at high speed, the addition of lubricating oil can form a fluid...
