[0026] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0027] Embodiment 1
[0028] Please refer to Figures 1 - 9 , the present utility model provides a technical solution: a sliding assembly, including a linear motor body 1, a drag chain 2 is installed at the rear side of the linear motor body 1, a stator 5 is installed at the bottom of the linear motor body 1, a rotor 4 is arranged at the left top of the stator 5, nylon sliders 6 are arranged on both the front and rear sides of the rotor 4, and a slide rail 3 is inserted at the bottom of the nylon slider 6. A plurality of first balls 7 are installed on both the left and right sides of the nylon slider 6, and a plurality of second balls 8 are installed on both the left and right sides of the bottom of the nylon slider 6. The adjacent sides of the front and rear first balls 7 are both attached to the middle of the slide rail 3, and the adjacent sides of the front and rear second balls 8 are both attached to the bottom of the slide rail 3.
[0029] First, start the linear motor body 1. An electromagnetic field is generated on the stator 5 through an alternating current, thereby generating a thrust on the mover 4 to achieve linear motion. When the mover 4 moves, it synchronously drives the nylon sliders 6 on both its front and rear sides to slide along the outer side of the slide rail 3. At the same time, a first ball 7 and a second ball 8 are respectively arranged in the middle and bottom of the nylon slider 6. At the same time, both the first ball 7 and the second ball 8 are in contact with the outer side of the slide rail 3. Thus, when the nylon slider 6 slides, the friction between it and the slide rail 3 is reduced, thereby improving the service life of the nylon slider 6 and at the same time improving the use effect of the linear motor.
[0030] Embodiment 2
[0031] On the basis of Embodiment 1, in order to improve the lubricity between the nylon slider 6 and the slide rail 3 and reduce the wear of the nylon slider 6, oil grooves 9 are opened on both the left and right sides of the nylon slider 6. A sealing baffle 12 is inserted into the top of the oil groove 9. A plurality of second through grooves 11 are opened at the bottom of the oil groove 9. A plurality of first through grooves 10 are opened on both the left and right sides of the bottom of the nylon slider 6; the bottom end of the second through groove 11 is arranged at the top of the first ball 7, the top ends of the front and rear first through grooves 10 are both arranged at the bottom of the first ball 7, and the bottom ends of the front and rear first through grooves 10 are respectively arranged on the separated sides of the front and rear second balls 8. Thus, the lubricating liquid in the oil groove 9 is guided to the surfaces of the first ball 7 and the second ball 8 through the first through groove 10 and the second through groove 11. Furthermore, when the nylon slider 6 moves, the lubricating liquid is coated on the outer side of the slide rail 3, thereby reducing the friction between the two and improving the service life of the nylon slider 6.
[0032] While the nylon slider 6 slides along the outer side of the slide rail 3, the lubricating liquid inside the oil groove 9 is guided to the outside of the first ball 7 through the second through groove 11. At the same time, the lubricating liquid outside the first ball 7 is guided to the surface of the second ball 8 through the first through groove 10. Thus, a layer of lubricating liquid is coated on the surfaces of both the first ball 7 and the second ball 8. At the same time, when the nylon slider 6 moves, the lubricant is coated on the outer side of the slide rail 3, thereby improving the lubricity of the outer side of the slide rail 3, further reducing the friction between the nylon slider 6 and the slide rail 3, and improving the service life of the slide rail 3.
[0033] Embodiment 3
[0034] On the basis of Embodiment 2, in order to facilitate maintenance personnel to add lubricating oil, a first chute 14 is opened at the top of the nylon slider 6. Two push blocks 15 are slidably connected to the inner wall of the first chute 14. Connecting rods 13 are installed on the separated sides of the left and right push blocks 15. Fixed connections are made between the separated ends of the left and right connecting rods 13 and the sealing baffle 12 respectively. Thus, by moving the push blocks 15, the sealing baffle 12 is driven to slide, thereby facilitating maintenance personnel to add lubricating oil to the inside of the oil groove 9.
[0035] After long-term use, the lubricating fluid inside the oil sump 9 is used up. At this time, squeeze the two push blocks 15 to slide along the inner wall of the first chute 14 towards the middle of the nylon slider 6, and at the same time drive the two connecting rods 13 to move synchronously, thereby driving the sealing baffle 12 to move. At this time, the lubricating fluid can be poured into the oil sump 9. After completion, the worker drives the two push blocks 15 to move to both sides of the slide rail 3 respectively, and drives the sealing baffle 12 to reset, so as to seal the oil sump 9 through the sealing baffle 12, which is convenient for maintenance personnel to use.
[0036] Embodiment 4
[0037] On the basis of Embodiment 3, in order to facilitate driving the sealing baffle 12 to reset for subsequent use, second chutes 17 are provided on both the left and right sides of the nylon slider 6, and moving plates 16 are installed on the inner walls of the second chutes 17. Thus, through the arrangement of the moving plates 16, the sealing baffle 12 moves more smoothly during the movement. Springs 18 are installed on the sides of the left and right moving plates 16 close to each other; the close ends of the left and right springs 18 are installed on the inner walls of the second chutes 17, and the moving plates 16 are installed on the outside of the connecting rods 13. Thus, the elastic force of the springs 18 is used to drive the sealing baffle 12 to reset, which is convenient for subsequent use.
[0038] When opening the sealing baffle 12, first squeeze the two push blocks 15 to move, and at the same time drive the moving plates 16 on the outside of the connecting rods 13 to slide along the inner walls of the second chutes 17, and squeeze the springs 18. At this time, the sealing baffle 12 can be opened. After the lubricating fluid is added, the maintenance personnel release the two push blocks 15, so as to use the elastic force of the springs 18 to drive the moving plates 16 to reset, and synchronously drive the sealing baffle 12 to reset, which is convenient for subsequent maintenance use.
[0039] Embodiment 5
[0040] On the basis of Embodiment 4, a linear motor is proposed, including a sliding assembly.
[0041] During actual use, first start the linear motor body 1, generate an electromagnetic field on the stator 5 through an alternating current, thereby generating a thrust on the mover 4 to achieve linear motion. When the mover 4 moves, it synchronously drives the nylon sliders 6 on its front and rear sides to slide along the outside of the slide rail 3. At the same time, balls 7 and balls 8 are respectively arranged in the middle and bottom of the nylon slider 6, and both the balls 7 and balls 8 are in contact with the outside of the slide rail 3. Thus, when the nylon slider 6 slides, the friction between it and the slide rail 3 is reduced, thereby improving the service life of the nylon slider 6 and at the same time improving the use effect of the linear motor.
[0042] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
