[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-9 As shown, a slider body for a linear guide slider comprises:

[0029] The slider body 1 has ball grooves 15 symmetrically formed therein;

[0030] The oil groove 14 is connected to the ball groove 15 through an oil injection channel 17. An oil injection nozzle 18 is provided at the oil outlet of the oil injection channel 17. A sealing ball 183 is provided in the oil injection nozzle 18. The sealing ball 183 is driven to move to control the opening / closing of the oil injection nozzle 18.

[0031] Specifically, sealing plates 2 are symmetrically arranged on the slider body 1 to seal the slider body 1 to prevent dust from entering the inside. The slider body 1 is slidably arranged on the linear rail through a slide groove 12 opened on the slider body 1, and oil is filled into the oil groove 14 through the oil filling port 11. Balls 151 are arranged in the ball groove 15. The balls 151 roll in the ball groove 15, so that the balls 151 roll along the linear guide rail as the slider body 1 slides, thereby reducing the friction between the slider body 1 and the linear rail.

[0032] Furthermore, the oil groove 14 enters the oil inlet channel 181 and the oval groove 184 in the oil injection nozzle 18 through the oil injection channel 17, and the blocking ball 183 blocks the oil outlet of the oval groove 184 under the push of the spring 182. Figure 4 As shown, when the slider body 1 slides along the linear guide rail, the ball 151 rolls in the ball groove 15, and the ball 151 contacts the sealing ball 183, and drives the sealing ball 183 to move in the elliptical groove 184 and squeeze the spring 182, so that the sealing ball 183 blocks the oil inlet of the elliptical groove 184, and opens the oil outlet of the elliptical groove 184, and squeezes the lubricating oil in the elliptical groove 184 through the oil outlet of the elliptical groove 184 to lubricate the ball 151, which can well control the discharge amount of the lubricating oil and will not cause excessive lubricating oil.

[0033] Furthermore, when the slider body 1 stops sliding, when the ball 151 is not in contact with the sealing ball 183, the spring 182 pushes the sealing ball 183 to seal the oil outlet of the elliptical groove 184; when the ball 151 is in contact with the sealing ball 183, the sealing ball 183 seals the oil inlet of the elliptical groove 184 driven by the ball 151, so that the oiling nozzle 18 remains in a closed state when the slider body 1 stops sliding and does not keep discharging oil, thereby effectively saving lubricating oil and extending the service life of the lubricating oil in the oil tank 14.

[0034] In the above technology, the oil groove 14 enters the oil inlet channel 181 and the oval groove 184 in the oil injection nozzle 18 through the oil injection channel 17, and the blocking ball 183 blocks the oil outlet of the oval groove 184 under the push of the spring 182. When the slider body 1 slides along the linear guide rail, the ball 151 rolls in the ball groove 15, and the ball 151 contacts the blocking ball 183, and drives the blocking ball 183 to move in the oval groove 184 and squeeze the spring 182, so that the blocking ball 183 blocks the oil inlet of the oval groove 184, opens the oil outlet of the oval groove 184, and squeezes the lubricating oil in the oval groove 184 through the oil outlet of the oval groove 184 to lubricate the ball 151, which can well The discharge amount of lubricating oil is controlled to avoid excessive lubricating oil. When the slider body 1 stops sliding and the ball 151 is not in contact with the sealing ball 183, the spring 182 pushes the sealing ball 183 to seal the oil outlet of the elliptical groove 184. When the ball 151 is in contact with the sealing ball 183, the sealing ball 183 seals the oil inlet of the elliptical groove 184 driven by the ball 151, so that the oiling nozzle 18 remains in a closed state when the slider body 1 stops sliding and oil is not discharged all the time, thereby effectively saving lubricating oil and extending the service life of the lubricating oil in the oil groove 14. Compared with the prior art, it is not only possible to well control the discharge amount of lubricating oil and improve the lubrication effect, but also effectively save lubricating oil.

[0035] As a further embodiment of the present invention, an oil guide groove 152 is provided on the groove wall at the bottom of the ball groove 15 .

[0036] Specifically, an oil return groove 19 is provided at the oil outlet of the oil guide groove 152, and the groove wall at the bottom of the oil guide groove 152 is inclined. With the continuous use of the slider body 1, the lubricating oil in the ball groove 15 will also accumulate, and the excess lubricating oil will enter the oil guide groove 152 at the bottom of the ball groove 15. Since the groove wall at the bottom of the oil guide groove 152 is inclined, the lubricating oil flows along the groove wall at the bottom of the oil guide groove 152 and enters the oil return groove 19 for recovery and collection, thereby recovering the excess lubricating oil, so that the excess lubricating oil will not stay in the ball groove 15 to affect the lubrication effect, while saving lubricating oil and effectively reducing costs.

[0037] As a further embodiment of the present invention, air channels 13 are symmetrically arranged inside the slider body 1 .

[0038] Specifically, Figure 3 As shown, the openings of the air channel 13 at both ends have large diameters, the middle section has a small diameter, and the openings are streamlined in design. When the slider body 1 slides, air passes through the air channel 13, which can reduce wind resistance and energy consumption.

[0039] As a further embodiment of the present invention, a heat-conducting metal piece 16 is symmetrically arranged inside the slider body 1 . The heat-conducting metal piece 16 includes a heat-conducting plate 162 and a first heat-conducting column 163 . A second heat-conducting column 164 is arranged in an array on the first heat-conducting column 163 .

[0040] Specifically, when the slider body 1 slides along the linear guide rail, as the ball 151 rolls in the ball groove 15, the temperature in the ball groove 15 increases, and the temperature of the lubricating oil in the ball groove 15 also increases along with the ball 151. The second heat-conducting column 164 is provided to contact and transfer heat with the lubricating oil in the ball groove 15, and the heat is transferred to the first heat-conducting column 163, and then transferred to the heat-conducting plate 162 through the first heat-conducting column 163 for heat dissipation. The lubricating oil circulates in the ball groove 15 along with the ball 151, thereby realizing cyclic heat conduction and heat dissipation, which can effectively dissipate the heat of the ball 151, the inside of the ball groove 15 and the inside of the slider body 1, thereby extending the service life of the slider body 1.

[0041] As a further embodiment of the present invention, the heat-conducting metal member 16 further includes an arc-shaped heat-conducting plate 161 , and the arc-shaped heat-conducting plate 161 is disposed in the air flow channel 13 .

[0042] Specifically, when the slider body 1 slides along the linear guide rail, as the ball 151 rolls in the ball groove 15, the temperature in the ball groove 15 increases, and the temperature of the lubricating oil in the ball groove 15 also increases along with the ball 151. The second heat-conducting column 164 is in contact with the lubricating oil in the ball groove 15 for heat transfer, and the heat is transferred to the first heat-conducting column 163, and then transferred to the heat-conducting plate 162 through the first heat-conducting column 163. The heat-conducting plate 162 further transfers the heat to the arc-shaped heat-conducting plate 161. As the air in the air flow channel 13 continues to enter and discharge, the heat on the arc-shaped heat-conducting plate 161 is taken away, thereby accelerating the heat dissipation and improving the heat dissipation effect.

[0043] Working principle: The slider body 1 is symmetrically provided with sealing plates 2 to seal the slider body 1 to prevent dust from entering the inside. The slider body 1 is slidably arranged on the linear track through the slide groove 12 opened on the slider body 1. Oil is injected into the oil groove 14 through the oil filling port 11. The ball 151 is arranged in the ball groove 15. The ball 151 rolls in the ball groove 15 so that the ball 151 rolls along the linear guide rail as the slider body 1 slides, thereby reducing the friction between the slider body 1 and the linear track. The oil groove 14 enters the oil inlet channel 181 and the elliptical groove 184 in the oil filling nozzle 18 through the oil filling channel 17. The sealing ball 183 pushes the elliptical groove 184 under the push of the spring 182. The oil outlet of 84 is blocked. When the slider body 1 slides along the linear guide rail, the ball 151 rolls in the ball groove 15, and the ball 151 contacts the blocking ball 183, and drives the blocking ball 183 to move in the elliptical groove 184 and squeeze the spring 182, so that the blocking ball 183 blocks the oil inlet of the elliptical groove 184, and opens the oil outlet of the elliptical groove 184, and the lubricating oil in the elliptical groove 184 is squeezed out through the oil outlet of the elliptical groove 184 to lubricate the ball 151, which can well control the discharge amount of the lubricating oil and will not cause excessive lubricating oil. An oil return groove 19 is provided at the oil outlet port of the oil guide groove 152, and the groove wall at the bottom of the oil guide groove 152 is inclined. As the slider body 1 is continuously used, the lubricating oil in the ball groove 15 will accumulate, and the excess lubricating oil will enter the oil guide groove 152 at the bottom of the ball groove 15. Since the bottom groove wall of the oil guide groove 152 is inclined, the lubricating oil flows along the bottom groove wall of the oil guide groove 152 and enters the oil return groove 19 for recovery and collection, thereby recovering the excess lubricating oil, so that the excess lubricating oil will not stay in the ball groove 15 to affect the lubrication effect, while saving lubricating oil and effectively reducing costs. The openings at both ends of the air flow channel 13 have a large diameter, a small diameter in the middle section, and a streamlined design. When the slider body 1 slides, air passes through the air flow channel 13, which can reduce Wind resistance is reduced, and energy consumption is reduced. When the slider body 1 slides along the linear guide rail, as the ball 151 rolls in the ball groove 15, the temperature in the ball groove 15 increases, and the temperature of the lubricating oil in the ball groove 15 also increases with the ball 151. The second heat-conducting column 164 is provided to contact the lubricating oil in the ball groove 15 for heat transfer, and the heat is transferred to the first heat-conducting column 163, and then transferred to the heat-conducting plate 162 through the first heat-conducting column 163. The heat-conducting plate 162 further transfers the heat to the arc-shaped heat-conducting plate 161. As the air in the air flow channel 13 continues to enter and discharge, the heat on the arc-shaped heat-conducting plate 161 is taken away, thereby accelerating the heat dissipation and improving the heat dissipation effect.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
