Description

Technical Field

[0001] The present application relates to the technical field of linear guide rails, and in particular to an inner slider of a linear guide rail with buffer protection. Background Art

[0002] A linear guide is a mechanical device used to achieve high-precision linear motion. It is mainly composed of two parts: a guide rail and a slider body. The guide rail is generally a track with high precision and good straightness. Its surface has been precisely machined and has extremely high flatness. The slider body fits tightly with the guide rail. The slider body contains rolling elements such as balls or rollers. When the slider body moves on the guide rail, these rolling elements roll between the slider body and the guide rail, allowing the slider body to perform high-precision linear motion with extremely low friction. Linear guides are widely used in various automation equipment, CNC machine tools, precision instruments and other fields. In automation equipment, it can ensure the precise positioning and smooth movement of mechanical parts; on CNC machine tools, linear guides ensure that the tool processes the workpiece along a precise straight path, greatly improving the processing accuracy;

[0003] In the current prior art, the linear guide rail and its slider body structure do not have a perfect buffer protection function in many cases. Taking a linear guide rail in the prior art as an example, during its application, when the slider body moves to the end of the guide rail, the slider body contacts the moving block, thereby driving the moving block to move inward. At this time, the connecting rod also moves accordingly, so that the first spring is compressed. The first spring can buffer the impact force of the slider body to a certain extent, thereby preventing the slider body from directly colliding with the limit block and avoiding damage to the slider body. At the same time, the buffer block can also buffer the impact of the slider body, and the moving block is forced to move inward and also drives the push block to slide in the slide groove. The push block transmits the impact force to the buffer column and the second spring, thereby further absorbing the impact force to enhance the buffering effect of the buffer mechanism;

[0004] However, this buffer design can only play a buffering and protective function for the slider body itself, and has obvious limitations. In the specific application process, it obviously lacks the buffering function for the device installed on the top of the slider body. Usually, some auxiliary processing devices or equipment are installed on the top of the slider body of the linear guide. During use, since the slider body often moves, it is inevitable that there will be bumps and shaking. This continuous movement state will obviously have an adverse effect on the device installed on its top, such as damage to the precision components inside the device, loose connection parts and other problems, thereby reducing the overall service life of the device. It can be seen that the existing linear guide and its slider body structure have certain defects and deficiencies in overall use in this regard, so it is urgent to improve it to meet the higher requirements in practical applications.

[0011] In a feasible implementation, balls are rotatably connected to the bottom of the bottom plate at equal intervals, and the bottom of the balls is fitted and connected to the top of the top plate.

[0012] In a feasible implementation, the top of the top plate is fixedly connected to a base frame, the top of the base frame is fixedly connected to a mounting plate, the four corners of the mounting plate are provided with mounting holes, the mounting holes are set as countersunk holes, the overall cross-sectional shape of the internal cavity of the slider body is convex, and the overall cross-sectional shape of the guide rail body is I-shaped.

[0014] The embodiment of the present application provides an inner slider of a linear guide with buffer protection. The linear guide is provided with an anti-collision buffer mechanism. Through the anti-collision plate and the anti-collision spring and anti-collision damper on the outside, it can effectively perform anti-collision buffering and damping when the slider body slides and collides, thereby improving the overall buffer protection performance. When in use, the device can be installed on the top base of the slider body using the mounting plate and the mounting hole. When the slider moves, the top buffer mechanism and the side buffer mechanism can be linked together for joint buffering.

[0015] The side buffer mechanism and top buffer mechanism of the device work well together. When the slider slides, the side buffer springs assist in buffering.

[0028] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will provide a clear and complete description of the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] Example

[0030] refer to Figures 1 to 4 The present embodiment provides a linear guide inner slider with buffer protection, comprising: a guide rail body 100, with anti-collision buffer mechanisms 200 fixedly connected to both sides of the guide rail body 100, a slider body 300 slidably connected to the outer surface of the guide rail body 100, a top plate 400 fixedly mounted on the top of the slider body 300, side buffer mechanisms 500 fixedly connected to the top of the top plate 400 in a 2*2 arrangement with equal spacing, and a top buffer mechanism 600 fixedly connected to the top of the side buffer mechanisms 500;

[0031] The side buffer mechanism 500 includes a side support plate 510, which is fixedly connected to the front and rear ends of the top of the top plate 400. The inner upper end of the side support plate 510 is hinged with a side buffer group 520. The inner side of the side buffer group 520 is hinged to the top buffer mechanism 600. The anti-collision buffer mechanism 200 on both sides of the guide rail body 100 can effectively prevent the slider body 300 from colliding with the two ends of the guide rail during the sliding process, thereby improving the overall safety. The top plate 400 on the top of the slider body 300 provides a stable safety for other structures. The side support plates 510 in the side buffer mechanism 500 are fixed on the top of the top plate 400 to provide support for the side buffer group 520. The side buffer group 520 is hinged to the top buffer mechanism 600. When the slider body 300 slides, no matter in which direction the force is applied, the side buffer group 520 can provide buffering through the hinge structure. Cooperating with the top buffer mechanism 600, it can provide all-round buffering protection for the slider body 300 and the top device, reduce the impact of bumps and shakes on the device, and improve the stability and service life of the linear guide.

[0032] The side buffer group 520 includes a first hinge ball 521, the first hinge ball 521 is rotatably connected to the upper end of the side support plate 510, the inner side of the first hinge ball 521 is fixedly connected to the side buffer spring 522, the inner end of the side buffer spring 522 is fixedly connected to the second hinge ball 523, the inner side of the side buffer spring 522 is hinged to the top buffer mechanism 600 through the second hinge ball 523, and the side damper 524 is fixedly connected between the inner sides of the first hinge ball 521 and the second hinge ball 523. Attached to the outside of the side damper 524, the first hinge ball 521 in the side buffer assembly 520 is pivotally connected to the upper end of the side support plate 510, providing a flexible pivot point for the connection between the side buffer spring 522 and the side damper 524. The side buffer spring 522 is hinged to the side support plate 510 and the top buffer mechanism 600 via the first hinge ball 521 and the second hinge ball 523, respectively. When the slider body 300 slides on the guide rail, the side buffer spring 522 responds quickly to external forces from any direction. Its elastic deformation absorbs impact forces, providing a buffering effect. Simultaneously, the side damper 524 and the side buffer spring 522 cooperate to dissipate energy during the buffering process, reducing rebound force and ensuring smoother buffering. The side buffer spring 522 is attached to the outside of the side damper 524, resulting in a compact design that effectively utilizes space. The interaction during operation enhances the buffering effect, strengthens the stability and reliability of the slider within the linear guide, and extends the service life of the equipment.

[0033] The top buffer mechanism 600 includes a top plate 610, which is hingedly mounted on the inner sides of four second hinge balls 523. Main buffer springs 620 are fixedly connected to the four corners of the bottom of the top plate 610. The bottom of the main buffer springs 620 is fixedly connected to the bottom of the bottom plate 630. Main dampers 640 are fixedly connected to the four corners of the top of the bottom plate 630. The top of the main damper 640 is connected to the bottom of the top plate 610. The main buffer springs 620 are sleeved around the outside of the main damper 640. Ball bearings 650 are rotatably connected to the bottom of the bottom plate 630 at equal intervals. The bottom of the ball bearings 650 is in contact with the top of the top plate 400. The top plate 610 is connected to the side buffer group 520 via the four second hinge balls 523, capable of receiving buffering forces from all directions, providing all-round buffering protection. When the slider body 300 is impacted, the main buffer springs 620 at the four bottom corners can absorb energy through elastic deformation, thus providing a buffering effect. The main damper 640 and main buffer spring 620 work together to effectively dissipate impact energy, reduce rebound, and provide smoother cushioning. The main buffer spring 620 is sheathed around the main damper 640, creating a compact structure that improves space utilization and allows for synergistic operation. Ball bearings 650 at the bottom of the base plate 630 are securely connected to the top of the top plate 400. As the top plate 610 moves up and down, the ball bearings 650 act as guides, reducing friction and ensuring a smooth cushioning process. This prevents friction from affecting the cushioning effect, thereby improving the overall cushioning protection and stability of the slider within the linear guide.

[0034] The top of the top plate 610 is fixedly connected to the base frame 700, and the top of the base frame 700 is fixedly connected to the mounting plate 800. The four corners of the mounting plate 800 are provided with mounting holes 900, and the mounting holes 900 are set as countersunk holes. The overall cross-sectional shape of the internal cavity of the slider body 300 is set in a convex shape, and the overall cross-sectional shape of the guide rail body 100 is set in an I-shaped shape. The anti-collision buffer mechanism 200 includes a side frame 210, and the side frame 210 is fixedly connected to the two ends of the guide rail body 100. The inner sides of the side frame 210 are fixedly connected to the anti-collision Spring 220. The inner end of the anti-collision spring 220 is fixedly connected to the anti-collision plate 230. The outer ends of the anti-collision plate 230 are fixedly connected to the anti-collision damper 240. The anti-collision spring 220 is sleeved on the outer side of the anti-collision damper 240. The base frame 700 and the mounting plate 800 on the top of the top plate 610 provide convenience for installing the required equipment. The mounting hole 900 is set as a countersunk hole, making the installation more beautiful and firm. The internal cavity of the slider body 300 is convex in shape, which fits tightly with the I-shaped guide rail body 100 to ensure that the slider slides stably on the guide rail. The side frame 210 in the anti-collision buffer mechanism 200 is fixed to both ends of the guide rail body 100. The internal anti-collision spring 220 and anti-collision damper 240 cooperate. When the slider body 300 slides to the end of the guide rail and hits the anti-collision plate 230, it can effectively perform anti-collision buffering and damping, improving overall safety and stability. This design fully considers the various needs of the slider in the linear guide during use, providing reliable guarantee for the normal operation of the equipment.

[0035] The principle of use and advantages are as follows: the linear guide rail can play a significant protective role during use through the anti-collision buffer mechanism 200 set up. Specifically, auxiliary protection can be provided by the anti-collision plate 230 on the outside of the anti-collision buffer spring. When the slider body 300 slides on the outside of the guide rail body 100, if the slider body 300 hits the anti-collision plate 230 on one side, the anti-collision spring 220 and the anti-collision damper 240 on the anti-collision plate 230 cooperate with each other to effectively perform anti-collision buffering and damping on the slider body 300, greatly improving the overall buffering protection performance of the device. In addition, during use, the required equipment can be installed on the base frame 700 on the top of the slider body 300 through the mounting plate 800 and the mounting hole 900. During the movement of the slider, the top buffer mechanism 600 and the side buffer mechanism 500 can be used for linkage and joint buffering.

[0036] By providing the side buffer mechanisms 500 and the top buffer mechanism 600 in coordination with each other, the device exhibits excellent cushioning performance during use. When the slider body 300 slides, the side buffer springs 522 provide auxiliary cushioning. When the side buffer springs 522 are pulled in either direction, they are assisted in articulation by the first hinge ball 521 and the second hinge ball 523. This ensures that the elastic force of all side buffer springs 522 acts on the central top plate 610. This means that during the sliding process of the slider body 300, regardless of the direction in which the slider body 300 slides, the side buffer springs 522 and side dampers 524 can exert elastic cushioning force on the top plate 610, significantly improving the overall protective cushioning performance of the device. Furthermore, during the cushioning process, when the top plate 610 moves up and down, this movement can also affect the main damper 640 and main buffer spring 620. The auxiliary cushioning provided by the main damper 640 and buffer springs further enhances the cushioning and protective performance of the top plate 610. The auxiliary, coordinated buffering provided by the side buffer springs 522, side dampers 524, and main buffer springs 620 and main dampers 640 significantly enhances the overall buffering and protective performance of the slider's top base 700. Furthermore, the bottom plate 630, affixed to the top of the top plate 400 and guided by the ball bearings 650, reduces friction on the bottom plate 630, preventing it from impacting the buffering effect of the side buffer springs 522. In summary, this device as a whole exhibits exceptionally strong buffering and protective performance.

[0037] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on the several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application.
