Description

Technical Field

[0001] The present invention belongs to the technical field of linear guides, and particularly relates to a linear motion guide rail. Background Art

[0002] In the past, in order to manufacture machines, it was necessary to separately select the methods of gear racks and linear guides to manufacture various mechanical equipment. This traditional design method requires a large amount of space and goes through multiple processing and assembly processes.

[0003] The prior art chose to perform hole machining on the guide rail and use pressure to press the pins in. However, this technology will generate stress during pressing. If the guide rail is deformed or the adjustment management during forced adaptation is insufficient, it may lead to the problem of pin detachment. At the same time, during the actual installation process of the linear guide rail, due to the level of the ground and long-term use wear, the top mounting brackets will be uneven, causing the upper mounting structure to tilt. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the present invention provides a linear motion guide rail that can overcome or at least partially solve the above problems.

[0005] The present invention is implemented as follows. A linear motion guide rail includes a slider for installation and fixation. A linear guide rail is slidably connected inside the slider. A plurality of adjusting bolt structures are arranged on the top of the linear guide rail;

[0006] A pin shaft is arranged on the top of the linear guide rail, and the bottom of the pin shaft extends into the linear guide rail;

[0007] The top of the adjusting bolt structure is detachably connected to a mounting bracket. A driving motor is arranged on one side of the linear guide rail. The output end of the driving motor is fixedly connected to a gear, and the surface of the gear meshes with the surface of the pin shaft.

[0008] Preferably, the plurality of adjusting bolt structures include a screw rod for connection and fixation. One end of the screw rod is fixedly connected to the surface of the linear guide rail. The other end of the screw rod penetrates through the mounting bracket and extends to the surface of the mounting bracket. A first nut for adjustment is arranged at the bottom of the mounting bracket, and the inside of the first nut is threadedly connected to the inside of the screw rod. A second nut for adjustment is arranged at the top of the mounting bracket, and the inside of the second nut is threadedly connected to the surface of the screw rod. Pass the screw rod through the mounting bracket. By adjusting the position of the first nut on the surface of the screw rod, the height of the mounting bracket can be adjusted. By pressing the second nut on the top of the mounting bracket and fixing the mounting bracket through the cooperation of the first nut and the second nut, the height of the mounting bracket can be adjusted.

[0009] Preferably, the surface of the mounting bracket is provided with first mounting holes for installation. The number of the first mounting holes is several, and they are symmetrically and evenly distributed in pairs. The surfaces of the first nut and the second nut are both used in cooperation with the surface of the mounting bracket, which can facilitate the installation of various working devices on the mounting bracket. The multiple first mounting holes can stably install the devices and are convenient for installing various devices.

[0010] Preferably, one side of the pin shaft is provided with a hexagonal counterbore for the rotation of the pin shaft. The bottom of the surface of the pin shaft is threadedly connected to the inside of the linear guide rail. The pin shaft can be rotated by inserting an internal hexagonal wrench into the hexagonal counterbore, so that the pin shaft is screwed into the inside of the linear guide rail, solving the problems of stress deformation and poor forced adaptation generated during pressure forming.

[0011] Preferably, the four corners of the surface of the slider are all provided with second mounting holes for the installation of the slider, which can fix the slider on the workbench and increase the stability of the slider.

[0012] Preferably, the top of the mounting bracket is provided with a counterbore for placing and installing the second nut, which can accommodate the second nut and facilitate the installation of the equipment above the mounting bracket.

[0013] Preferably, there are multiple groups of sliders, and all the multiple groups of sliders are used in cooperation with the surface of the linear guide rail. By installing one or more than two sliders on the surface of the linear guide rail, the linear guide rail can be stably guided.

[0014] Preferably, both sides of the linear guide rail are in an R shape or a V shape. Through the R-shaped or V-shaped linear guide rail, more precise position control and reduction of object shaking can be achieved.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] By setting up the structures of the slider, linear guide rail, pin shaft, mounting bracket and adjusting bolt, by machining threads in the holes on the guide rail and using wrench tools for assembly, the problems of stress deformation and poor forced adaptation generated during pressure forming are solved. Through the adjusting bolt structure, the mounting bracket at the top can be leveled to avoid the inclination of the upper structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0024] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] As Figures 1 to 5 shown, a linear motion guide rail provided by an embodiment of the present invention includes a slider 1 for installation and fixation. A linear guide rail 2 is slidably connected inside the slider 1. A plurality of adjusting bolt structures are provided on the top of the linear guide rail 2. A pin shaft 3 is provided on the top of the linear guide rail 2. The bottom of the pin shaft 3 extends into the interior of the linear guide rail 2. The top of the adjusting bolt structure is detachably connected to a mounting bracket 4. A drive motor 5 is provided on one side of the linear guide rail 2. The output end of the drive motor 5 is fixedly connected to a gear 6. The surface of the gear 6 meshes with the surface of the pin shaft 3.

[0026] The multi-group adjusting bolt structure includes a screw rod 7 for connecting and fixing. One end of the screw rod 7 is fixedly connected to the surface of the linear guide 2, and the other end of the screw rod 7 penetrates through the mounting bracket 4 and extends to the surface of the mounting bracket 4. A first nut 8 for adjustment is provided at the bottom of the mounting bracket 4. The inside of the first nut 8 is threadedly connected to the inside of the screw rod 7. A second nut 9 for adjustment is provided at the top of the mounting bracket 4. The inside of the second nut 9 is threadedly connected to the surface of the screw rod 7. Pass the screw rod 7 through the mounting bracket 4. By adjusting the position of the first nut 8 on the surface of the screw rod 7, the height of the mounting bracket 4 can be adjusted. By pressing the second nut 9 against the top of the mounting bracket 4 and fixing the mounting bracket 4 through the cooperation of the first nut 8 and the second nut 9, the height of the mounting bracket 4 can be adjusted. A first mounting hole 10 for mounting is provided on the surface of the mounting bracket 4. The number of the first mounting holes 10 is several, and they are symmetrically and evenly distributed in pairs. The surfaces of the first nut 8 and the second nut 9 are used in cooperation with the surface of the mounting bracket 4, which can facilitate the installation of various working devices on the mounting bracket 4. The multiple first mounting holes 10 can stably mount the devices and facilitate the installation of multiple devices. A hexagonal counterbore 11 for the rotation of the pin shaft 3 is provided on one side of the pin shaft 3. The bottom of the surface of the pin shaft 3 is threadedly connected to the inside of the linear guide 2. The pin shaft 3 can be rotated by inserting an internal hexagon into the hexagonal counterbore 11, so that the pin shaft 3 is screwed into the inside of the linear guide 2, solving the problems of stress deformation and poor forced adaptation generated during pressure forming. Second mounting holes 12 for mounting the slider 1 are provided at the four corners of the surface of the slider 1, which can fix the slider 1 on the workbench and increase the stability of the slider 1. A counterbore 13 for placing and mounting the second nut 9 is provided at the top of the mounting bracket 4, which can accommodate the second nut 9 and facilitate the installation of the equipment above the mounting bracket 4. The slider 1 is in multiple groups, and multiple groups of sliders 1 are all in cooperation with the surface of the linear guide 2. By installing one or more than two sliders 1 on the surface of the linear guide 2, the linear guide 2 can be stably guided. The two sides of the linear guide 2 are in an R shape or a V shape. Through the linear guide 2 in an R shape or a V shape, more precise position control and reduction of object shaking can be achieved.

[0027] The working principle of the present invention:

[0028] In use, the slider 1 is installed on the workbench through the second mounting hole 12. One or more sliders 1 are installed. The linear guide rail 2 is inserted into the slider 1. The inner hexagon is inserted into the hexagon counterbore 11 to rotate the pin shaft 3, so that the pin shaft 3 is screwed into the inside of the linear guide rail 2. The slider 1 is fixed while the rail moves linearly. By designing the pin shaft 3 with a special spacing and adjusting the position of the first nut 8 on the surface of the screw rod 7, the height of the mounting bracket 4 can be adjusted. The second nut 9 presses on the top of the mounting bracket 4, and the mounting bracket 4 is fixed by the cooperation of the first nut 8 and the second nut 9. After the adjustment of the mounting bracket 4 is completed, various working devices can be installed on the mounting bracket 4 through the first mounting hole 10. After the installation is completed, the gear 6 is engaged on the surface of the pin shaft 3, and the driving motor 5 is started. The driving motor 5 drives the gear 6 to rotate. The gear 6 pushes the pin shaft 3 to move. The pin shaft 3 drives the linear guide rail 2 to move. The linear guide rail 2 drives the screw rod 7 to move. Since the first nut 8 and the second nut 9 fix the mounting bracket 4, the screw rod 7 can drive the mounting bracket 4 to move linearly, thereby driving the equipment above the mounting bracket 4 to move.

[0029] In this technical solution, the installation method, usage method and connection method of the slider 1, the linear guide rail 2 and the driving motor 5 are all well-known common knowledge to those skilled in the art, so excessive technical descriptions are not given in this application document.
