Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a linear guide slider. Background Technology

[0002] A linear guide slider typically consists of two parts: the slider itself and the guide rail. The guide rail is usually fixed to an assembly such as a machine tool, while the slider contacts the guide rail through a linear bearing to achieve linear motion.

[0003] The working principle of a linear guide slider is based on rolling or sliding friction between the guide rail and the slider. In the case of rolling friction, the slider contains rolling elements (such as balls or rollers) that roll between the guide rail and the slider, greatly reducing friction and allowing the slider to move smoothly on the guide rail. Sliding friction, on the other hand, achieves linear motion through direct contact between the slider and the guide rail, but the friction is relatively large.

[0004] For example, utility model application CN202421140276.5 discloses a linear guide slider tooling for machining, including a slider body, through holes at the four corners of the slider body, and adjustment holes on the upper surface of the slider body. A support mechanism is movably installed in the mounting groove. The support mechanism includes a mechanism housing movably installed in the mounting groove. A lifting leg is fixedly installed on the upper end of the mechanism housing. A spring is connected to the lifting leg. A positioning shaft is installed inside the mechanism housing. A support roller is movably installed on the positioning shaft. An adjustment mechanism is provided in the adjustment hole.

[0005] However, in dusty environments, the fine and ubiquitous dust particles can accumulate on the guide rail and slider surfaces over time. Dust entering the slider mixes with the grease, forming solids that affect its lubricating effect. This increases the slider's sliding resistance on the guide rail and may even prevent the slider from sliding properly.

[0006] In view of this, we have studied and improved the existing structure and its shortcomings, and provided a linear guide slider. Utility Model Content

[0007] The purpose of this invention is to provide a linear guide slider to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A linear guide slider includes a rectangular block, with rollers movably mounted at each of the four corners of the bottom wall of the rectangular block. The rollers have an "I"-shaped cross-section, and their outer walls contact the linear guide.

The cleaning part includes a first scraper unit and a second scraper unit. The first scraper unit includes a pentagonal prism scraper, and the second scraper unit includes a wheel surface scraper and a support column.

[0010] According to the linear guide slider, threaded holes are provided on the outer walls of the opposite sides of the rectangular block, and the locking plate is U-shaped and is movably locked with the rectangular block.

[0011] According to the linear guide slider, a screw is threadedly connected at the middle position of the locking plate, and the screw moves through the locking plate and is threadedly fixed in the threaded hole.

[0012] According to the linear guide slider, the first scraper unit further includes a rectangular block and an oblique scraper. The two sides of the oblique scraper and the pentagonal scraper are on the same plane, and the two sides of the oblique scraper and the pentagonal scraper are in contact with the linear guide.

[0013] According to the linear guide slider, the rectangular block is fixedly installed on the side of the pentagonal prism scraper away from the linear guide, and the diagonal rod is fixedly connected between the rectangular block and the locking plate.

[0014] According to the linear guide slider, the annular block is sleeved on the outer wall of the roller, the roller and the annular block do not contact each other, there are two sets of annular blocks, and an arc-shaped mounting plate is fixedly connected between the two sets of annular blocks.

[0015] According to the linear guide slider, a trapezoidal plate is fixedly connected between the circular block and the rectangular block. The trapezoidal plate, the circular block, and the arc-shaped mounting plate are on the same plane. The support column is fixedly installed on both sides of the top and bottom of the arc-shaped mounting plate. The wheel scraper is fixedly connected to the support column. The side of the wheel scraper away from the support column is arc-shaped, and the wheel scraper is in contact with the corresponding roller.

[0016] This utility model provides a linear guide slider, which has the following advantages:

[0017] (1) By setting rollers to be movably installed at the four corners of the bottom wall of the rectangular block, the rectangular block slides on the linear guide rail through the rollers. Compared with the traditional slider, this device is suitable for working environments with a lot of dust and is not afraid of dust intrusion. By setting a cleaning component between the roller and the linear guide rail, a first scraper unit is set to clean the dust accumulated on the linear guide rail, and a second scraper unit is set to clean the dust on the outer wall of the roller. Automatic cleaning is achieved during the movement, reducing the sliding resistance between the roller and the guide rail and maintaining its good working condition.

The two ends of the trapezoidal plate are respectively connected to the ring block and the rectangular block. The trapezoidal plate, the ring block and the arc mounting plate are on the same plane. Together with the oblique rod and the arc mounting plate, they form a trapezoid, which enhances the stability of the device structure. The support column is fixedly installed on the top and bottom sides of the arc mounting plate. The side of the wheel scraper away from the support column is arc-shaped. The wheel scraper is in contact with the corresponding roller. During the rotation of the roller, the dust is scraped off by the wheel scraper. Attached Figure Description
