Technical Field

[0001] The utility model belongs to the technical field of guide rails and relates to a high-temperature resistant linear rolling guide rail structure. Background Art

[0002] Rolling linear guides, with their unique characteristics, have gradually replaced traditional sliding linear guides and are widely used in industrial production. They meet today's machinery requirements for high precision, high speed, energy conservation, and shortened product development cycles, and are widely used in various heavy-duty modular machine tools, CNC machine tools, high-precision EDM machines, grinders, industrial robots, and even general industrial machinery. Domestic manufacturing of rolling linear guides is still in its early stages, characterized by limited variety, low production volumes, susceptible ball bearings, short service life, and high noise levels.

However, during operation, this solution still has difficulty in quickly dissipating the heat at the ball and between the ball and the guide rail contact surface, which affects the service life of the guide rail and has the defect of relatively poor heat dissipation.

[0026] In this embodiment, during use, the ball-fixed slider 2 is rolled with the guide rail body 1 through the ball member 3. When the ball-fixed slider 2 moves back and forth along the track of the guide rail body 1, the outside air can enter the ball-fixed slider 2 through the air-intake type heat dissipation connecting component 5 and the auxiliary air inlet 6, and send the air to the ball member 3 that is running continuously, so as to quickly dissipate heat and cool down the ball member 3 and the contact surface of the guide rail body 1 that cooperates with the ball member 3. Part of the heat can also be discharged from the bottom of the guide rail body 1 through the inner heat dissipation structure 7, which plays a role in auxiliary heat dissipation. By adding multiple air inlet and outlet cooling structures, rapid heat dissipation can be achieved during the operation of the linear guide rail, and the high temperature resistance of the guide rail can be increased, thereby improving the service life of the rail.

[0027] Combine Figure 1-3 As shown, the air-inlet type counter-position heat dissipation connection component 5 includes a main air-inlet channel 8 arranged in the ball-fixing slider 2, and the main air-inlet channel 8 is arranged to penetrate along the front-to-back direction of the ball-fixing slider 2.

The heat dissipation connection part 9 includes an outer heat dissipation connection groove 10 arranged in the ball-fixing slider 2, and the width of the outer heat dissipation connection groove 10 is smaller than the diameter of the ball member 3.

[0028] Specifically, when the ball fixed slider 2 moves back and forth along the track of the guide rail body 1, the outside air can be sent into the continuously running ball component 3 through the main air inlet channel 8 and the outer heat dissipation connecting groove 10, so as to quickly dissipate heat and cool down the ball component 3 and the contact surface of the guide rail body 1 that cooperates with the ball component 3.

[0029] Combine Figure 1 、 Figure 2 As shown, the diameter of the main air inlet channel 8 is greater than the width of the outer heat dissipation connecting groove 10.

[0030] In this embodiment, the diameter of the main air inlet channel 8 is greater than the width of the outer heat dissipation connecting groove 10, so the air intake volume is relatively large.

[0031] The auxiliary air inlet portion 6 includes an upper air inlet channel 11 and a lower air inlet channel 12 arranged in the ball fixing slider 2. The upper air inlet channel 11 and the lower air inlet channel 12 are respectively connected to the outer heat dissipation connecting groove 10 through a connecting portion 13. The connecting portion 13 includes a connecting side groove 14 arranged in the ball fixing slider 2. One side of the connecting side groove 14 is connected to the upper air inlet channel 11 or the lower air inlet channel 12, and the other side is connected to the outer heat dissipation connecting groove 10.

[0032] In this embodiment, when the ball fixed slider 2 moves back and forth along the track of the guide rail body 1, the outside air can also enter the ball fixed slider 2 through the upper air inlet channel 11 and the lower air inlet channel 12, and then the air is sent to the outer heat dissipation connecting groove 10 and the ball member 3 through the connecting side groove 14, further increasing the air inlet area and improving the cooling and heat dissipation effect.

[0033] The upper air inlet duct 11 is located above the main air inlet duct 8, and the lower air inlet duct 12 is located below the main air inlet duct 8. The apertures of the upper air inlet duct 11 and the lower air inlet duct 12 are smaller than the aperture of the main air inlet duct 8.

[0034] In this embodiment, the apertures of the upper air inlet channel 11 and the lower air inlet channel 12 are smaller than the aperture of the main air inlet channel 8 to avoid the combined aperture being too large and affecting the structural strength of the ball-fixed slider 2 .

[0035] Combine Figure 1-2 As shown, the inner heat dissipation structure 7 includes an inner heat dissipation channel 15 provided in the guide rail body 1 , the inner heat dissipation channel 15 opens downward, and the inner heat dissipation channel 15 is connected to the ball member 3 via an inner connecting groove 16 .

[0036] In this embodiment, during operation, a portion of the heat can also be discharged from the bottom of the guide rail body 1 through the inner connecting groove 16 and the inner heat dissipation channel 15, playing a role in auxiliary heat dissipation.

[0037] Combine Figure 1-3 As shown, the detachable connecting plate 4 is fixed to the ball-fixing slider 2 by bolts, and assembly and disassembly are simple and convenient.

[0038] Combine Figure 1-3 As shown, the front and rear ends of the ball fixing slider 2 are provided with cover plates 18 , and the detachable connecting plate 4 and the ball fixing slider 2 are respectively fixedly connected to the cover plates 18 by bolts.

When the ball-fixed slider 2 moves back and forth along the track of the guide rail body 1, the outside air can be sent into the non-stop running ball member 3 through the main air inlet channel 8 and the outer heat dissipation connecting groove 10, so as to quickly dissipate heat and cool down the ball member 3 and the contact surface of the guide rail body 1 matched with the ball member 3. Part of the heat can also be discharged from the bottom of the guide rail body 1 through the inner connecting groove 16 and the inner heat dissipation channel 15, which plays a role in auxiliary heat dissipation. By adding multiple air inlet and outlet cooling structures, rapid heat dissipation can be achieved during the operation of the linear guide rail, and the high temperature resistance of the guide rail can be increased, thereby improving the service life of the rail.

[0042] The diameter of the main air inlet channel 8 is larger than the width of the outer heat dissipation connecting groove 10, and the air intake volume is large. When the ball fixed slider 2 moves forward and backward along the track of the guide rail body 1, the outside air can also enter the ball fixed slider 2 through the upper air inlet channel 11 and the lower air inlet channel 12, and then the air is sent to the outer heat dissipation connecting groove 10 and the ball member 3 through the connecting side groove 14, further increasing the air intake area and improving the cooling and heat dissipation effect.

[0043] The apertures of the upper air inlet duct 11 and the lower air inlet duct 12 are smaller than those of the main air inlet duct 8 to avoid the combined aperture being too large and affecting the structural strength of the ball-fixing slider 2. The cover plate 18 can prevent the ball member 3 from falling out. The detachable connecting plate 4 and the ball-fixing slider 2 are respectively fixed to the cover plate 18 by bolts, making disassembly and assembly simple and convenient.
