Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a novel linear guide rail device. Background Art

[0002] Linear guides, also known as line rails, slide rails, linear guides or linear slides, are moving parts used to support and guide. They perform reciprocating linear motion in a given direction and can achieve high-precision linear motion under high loads. Linear guides generally include guide rails and sliders. According to the friction relationship between the slider and the guide rail, they can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. In order to ensure smooth sliding of linear guides, it is necessary to apply lubricating oil to the guide rails regularly, and then disassemble them for maintenance. The operation is cumbersome and inefficient, and the uniformity of applying lubricating oil is poor, resulting in low utilization of lubricating oil and waste of lubricating oil.

[0003] To this end, we propose a new linear guide device. Utility Model Content

[0006] Furthermore, the four mounting grooves are distributed in a circular shape with equal spacing.

[0007] Furthermore, the inner wall surfaces of the four installation grooves on one side away from the linear guide rail body are semicircular and matched with the outer wall surfaces of the four lubrication rollers.

[0008] Furthermore, one end of the four lubricating rollers away from the linear guide rail body is in close contact with a side wall surface of the four mounting grooves away from the linear guide rail body.

[0009] Furthermore, the four lubrication rollers are distributed in a ring-shaped state with equal spacing.

[0015] Beneficial Effects

[0016] The utility model provides a novel linear guide device, which has the following beneficial effects:

[0017] 1. A novel linear guide device is provided with a lubrication mechanism. When in use, the lubricating oil is injected into the lubricating oil storage chamber through the oil filling threaded through hole, the lubricating oil enters the lubrication channel through the oil outlet through hole, and then enters the four installation grooves through four linear through grooves to contact with four lubricating rollers. When the slider moves linearly along the linear guide, the four lubricating rollers are forced to roll along the outer wall surface of the linear guide, and then the lubricating oil is evenly applied to the outer wall surface of the linear guide. The above operation is simple and practical, the structure is reasonable and compact, the convenience of using the device is improved, and the utilization rate of the lubricating oil is also improved to avoid wasting the lubricating oil and improve the practicality of the device.

[0018] 2. This novel linear guide device is provided with lubricating rollers. Since the outer walls of the four lubricating rollers are adapted to and in close contact with the wall of one side of the four mounting grooves away from the linear guide body, when the slider is in a stationary state, the outer walls of the four lubricating rollers block the four linear grooves, so that the lubricating oil inside the lubrication channel will not be lost through the linear grooves and the mounting grooves to cause waste, thereby improving the practicality of the device.

[0019] 3. This novel linear guide device is provided with a lubricating oil storage chamber. Since the inner bottom end of the lubricating oil storage chamber is funnel-shaped, the lubricating oil can be fully discharged into the lubrication channel through the oil outlet hole, and then the lubrication operation is performed, thereby further improving the utilization rate of the lubricating oil of the equipment.

Lubrication mechanisms are arranged inside the four mounting grooves 13, and the lubrication mechanisms include lubrication rollers 15 that are rotatably connected to the inside of the mounting grooves 13. The four mounting grooves 13 are distributed in a circular state with equal spacing. The wall surface of one side of the inner part away from the linear guide body 10 is in a semicircular arc shape and matches with the outer wall surfaces of the four lubricating rollers 15. One end of the four lubricating rollers 15 away from the linear guide body 10 is in close contact with the wall surface of one side of the inner part of the four mounting grooves 13 away from the linear guide body 10.

[0032] During the implementation of the utility model, since the inner bottom end of the lubricating oil storage chamber 17 is funnel-shaped, the lubricating oil can be fully discharged into the lubricating channel 12 through the oil outlet hole 18, thereby performing lubrication operation, further improving the utilization rate of the lubricating oil of the equipment.

[0033] The working principle of the utility model is as follows: when in use, the lubricating oil is injected into the lubricating oil storage chamber 17 through the oil filling threaded through hole 19, the lubricating oil enters the lubricating channel 12 through the oil outlet through hole 18, and then enters the four mounting grooves 13 through four linear through grooves 14 to contact the four lubricating rollers 15.
