Description

TECHNICAL FIELD

[0001] The application relates to the technical field of guide rail slider sealing, in particular to a guide rail slider dustproof sealing cover, a guide rail slider and an assembling process of the two. BACKGROUND

[0002] The guide rail slider is widely applied to numerical control machine tools, industrial robots and other precision mechanical equipment. As a key component for bearing and guiding, the guide rail slider is often exposed to the external environment during operation and is easily affected by dust, particles, liquid and other pollutants. In long-term operation, the entry of the pollutants not only accelerates the wear of the guide rail and the slider, but also causes the guiding precision to decrease, thereby affecting the service life and machining precision of the whole equipment. In order to solve this problem, a dustproof sealing structure is usually arranged at both ends of the guide rail slider to prevent the external pollutants from entering the slider.

[0003] The existing guide rail slider dustproof sealing device is mainly realized through a physical contact type sealing piece. Although the bolts can fix the guide rail slider and the sealing gasket together during assembly, the offset problem between the sealing gasket and the slider may still occur. The reasons for the offset may include uneven bolt pre-tightening force, alignment error during installation, tolerance problem of the sealing gasket, action of external force and insufficient friction during the assembly process and the like.

The sealing strip 13 extends out from the installation channel 12 and abuts against the outer peripheral surface of the rail.

[0056] like Figure 2 , Figure 3 and Figure 4 A sealing module 5 is provided between the first sealing sheet 1 and the second sealing sheet 2. The sealing module 5 is provided with an air injection chamber 51 and an oil injection chamber 52. An exhaust channel 53 is provided on the side of the sealing module 5 facing the guide rail. The exhaust channel 53 is opened along the contour of the sealing module 5 and is connected to the air injection chamber 51. The sealing strip 13 extends into the exhaust channel 53 on the side away from the guide rail. The first sealing sheet 1 is provided with an oil inlet hole 14 that is connected to the oil injection chamber 52.

[0057] The sealing module 5 includes two side sealing blocks 54 and one upper sealing block 55. A first guide strip 31 is integrally formed on the connecting plate 3. The first guide strip 31 is flush with the side of the connecting plate 3 away from the guide rail. A first guide groove 541 is opened on the side of the side sealing block 54 facing the connecting plate 3 (i.e., the bottom of the side sealing block 54). The first guide groove 541 extends to the side of the side sealing block 54 that is away from and facing the guide rail.

[0058] The side sealing block 54 is provided with a second guide strip 542 on one side thereof facing the upper sealing block 55, and the second guide strip 542 is flush with the side of the side sealing block 54 away from the connecting plate 3, i.e. the top of the side sealing block 54. The upper sealing block 55 is provided with a second guide groove 551 on one side thereof facing the side sealing block 54, and the second guide groove 551 penetrates to the side of the upper sealing block 55 away from and facing the guide rail, i.e. the top and bottom of the upper sealing block 55.

[0059] The two sides of the upper sealing block 55 are respectively spliced with one side sealing block 54. The upper sealing block 55 is provided with a first air channel 552 on one side thereof facing the guide rail. The side sealing block 54 is provided with a second air channel 543 on one side thereof facing the guide rail. The first air channel 552 and the second air channel 543 are connected to form an exhaust channel 53. The upper sealing block 55 is provided with a first air cavity 553 and a first oil cavity 554. The side sealing block 54 is provided with a second air cavity 544 and a second oil cavity 545. The first air cavity 553 and the second air cavity 544 form a gas injection chamber 51.

The upper sealing block 55 is provided with a first gas injection hole 555 and a first oil injection hole 556 on one side thereof away from the guide rail, i.e. the top of the upper sealing block 55. The side sealing block 54 is provided with a second gas injection hole 546 and a second oil injection hole 547 on one side thereof away from the guide rail. The first gas injection hole 555 and the second gas injection hole 546 are provided with a one-way valve 548. The first oil injection hole 556 and the second oil injection hole 547 are covered with a sealing plug 549. The first sealing sheet 1 is provided with three oil inlet holes 14. The side of the upper sealing block 55 facing the first sealing sheet 1 and the side of the side sealing block 54 facing the first sealing sheet 1 are in communication with the corresponding oil inlet holes 14.

[0061] The side wall of the first sealing sheet 1, the side wall of the side sealing block 54, the side wall of the first guide strip 31 and the side wall of the second sealing block are jointly provided with a first fixing bolt 15. The side wall of the first sealing sheet 1, the side wall of the upper sealing block 55 and the side wall of the second sealing sheet 2 are jointly provided with a second fixing bolt 22.

[0062] As shown in Figure 2 and Figure 5 , the bottom surface of the lower mounting strip 4 is provided with a first plug-in groove 41. The bottom surface of the first sealing sheet 1, the connecting plate 3 and the second sealing sheet 2 is collectively provided with a second plug-in groove 32. The first plug-in groove 41 is in communication with the second plug-in groove 32. A dustproof strip 6 is jointly inserted into the first plug-in groove 41 and the second plug-in groove 32.

[0063] The dustproof strip 6 comprises a plug-in part 61, a first abutting part 62 and two second abutting parts 63. The length of the plug-in part 61 is equal to the total length of the first plug-in slot 41 and the second plug-in slot 32. The plug-in part 61 is located in the first plug-in slot 41 and the second plug-in slot 32. The first abutting part 62 and the second abutting part 63 are integrally formed. The first abutting part 62 is located at the middle section of the plug-in part 61. The end of the first abutting part 62 away from the plug-in part 61 abuts against the guide rail. The middle section of the first abutting part 62 leaves a space with the guide rail.

[0064] The second abutting part 63 is located at the end of the plug-in part 61. The second abutting part 63 connects with the first abutting part 62. The second abutting part 63 is spliced with the sealing strip 13 and abuts against the guide rail.

[0065] The first abutting bolt 42 is threadedly connected to the lower mounting strip 4. The second abutting bolt 33 is threadedly connected to the connecting plate 3. The first abutting bolt 42 and the second abutting bolt 33 pass through the side of the lower mounting strip 4 away from the guide rail and abut against the plug-in part 61.

[0066] The sealing strip 13 is placed in the mounting channel 12 between the first sealing sheet 1 and the second sealing sheet 2. Then, the first guide slot 541 is aligned with the first guide strip 31. The side sealing block 54 is inserted between the first sealing sheet 1 and the second sealing sheet 2. Then, the second guide slot 551 is aligned with the second guide strip 542. The upper sealing block 55 is inserted between the first sealing sheet 1 and the second sealing sheet 2. The first fixing bolt 15 and the second fixing bolt 22 are installed. The first fixing bolt 15 and the second fixing bolt 22 are threadedly connected to the sliding block.

[0067] The connecting plate 3 is installed on the sliding block. Then, the dustproof strip 6 is installed. The first abutting bolt 42 and the second abutting bolt 33 are adjusted so that the dustproof strip 6 is attached to the side wall of the guide rail.

[0068] After the lubricating oil is injected into the first oil cavity 554 and the second oil cavity 545, the sealing plug 549 is covered. Then, the gas is injected into the first gas cavity 553 and the second gas cavity 544. The gas pushes the sealing strip 13 through the exhaust channel 53 so that the sealing strip 13 is attached to the guide rail, and the sealing is completed.

[0069] The sealing mode has strong self-adaptive adjustment capability. The gas injection chamber 51 can adjust the pressure to make the sealing strip 13 better attached to the surface of the guide rail. Even if the guide rail has slight wear or uneven surface, or there is alignment tolerance during installation, or the bolt pre-tightening force is different, the sealing strip 13 can dynamically adjust the deformation, so that the sealing effect is always good.

[0070] The adjustable pressure provided by the gas injection chamber 51 can not only solve the problem of different sealing needs in different environments, but also prevent the sealing strip 13 from causing wear to the surface of the guide rail due to being too tight.

[0071] Since the sealing strip 13 can be deformed and self-adapted through the adjustment of the air cavity, not only the wear of the sealing strip 13 and the guide rail can be reduced, but also the service life of the sealing strip 13 itself can be prolonged.

[0072] And the dustproof strip 6 can seal the gap between the bottom surface of the guide rail slider and the guide rail, preventing dust and particles from entering the inside of the guide rail slider from the bottom of the guide rail slider, effectively improving the running stability and service life of the slider. At the same time, the design of the first abutting portion 62 leaves a certain space when in contact with the guide rail, which can buffer the friction of the guide rail slider during operation, reduce wear, thereby prolonging the service life of the dustproof strip 6 and ensuring smooth movement of the guide rail slider. The second abutting portion 63 is spliced with the sealing strip 13, which seals the side and bottom of the end surface of the guide rail slider, avoiding dust from passing between the sealing strip 13 and the second abutting portion 63, further improving the sealing effect.

[0073] As Figure 6 and Figure 7 , the application embodiment also provides a guide rail slider connected with the guide rail slider dustproof sealing cover described above, comprising a shell 7, the shell 7 is provided with two connecting grooves 71 along the length direction thereof, the lower mounting strip 4 is embedded in the connecting grooves 71 and is adapted thereto, and the shell 7 is provided with three sliding channels 72 at both ends thereof, a spring 73 is arranged in each sliding channel 72, the spring 73 is connected with an oil injection pipe 74, the oil injection pipe 74 opposite to the upper sealing block 55 corresponds to the first oil injection hole 556 one by one, and the oil injection pipe 74 opposite to the side sealing block 54 corresponds to the second oil injection hole 547 one by one. The oil injection pipe 74 is provided with a guide surface 741 on the circumferential surface of the end thereof away from the spring 73.

[0074] When the side sealing block 54 and the upper sealing block 55 are inserted into the first sealing sheet 1 and the second sealing sheet 2, the side sealing block 54 and the upper sealing block 55 abut against the oil injection pipe 74 extending into the sliding channel 72, and when the side sealing block 54 and the upper sealing block 55 are installed in place, the oil injection pipe 74 is just aligned with the first oil injection hole 556 and the second oil injection hole 547, at this time, the oil injection pipe 74 extends into the first oil cavity 554 and the second oil cavity 545 under the action of the spring 73, plays a role of positioning and adjusting, and facilitates assembly. The connecting groove 71 also plays a role of positioning, ensuring that the first sealing sheet 1 can be opposite to the guide rail slider, facilitating the next step of installation.
