Description

Technical Field

[0001] The present application relates to the technical field of guide rail slider sealing, and in particular to a guide rail slider dustproof sealing cover, a guide rail slider and an assembly process thereof. Background Art

[0002] Guide rails and sliders are widely used in CNC machine tools, industrial robots and other precision mechanical equipment. As key components for bearing and guiding, guide rails and sliders are often exposed to the external environment during operation and are easily affected by pollutants such as dust, particles, and liquids. During long-term operation, the entry of pollutants will not only accelerate the wear of the guide rails and sliders, but also cause the guide accuracy to decrease, thus affecting the service life and processing accuracy of the entire equipment. In order to solve this problem, dustproof sealing structures are usually set at both ends of the guide rail slider to prevent external pollutants from entering the slider.

[0003] The existing guide rail slider dustproof sealing device is mainly realized by physical contact seals. When the guide rail slider and the sealing gasket are assembled, although the bolts can fix the two together, there may still be a problem of offset between the sealing gasket and the slider. The specific reasons for the offset may be uneven bolt preload, alignment error during installation, tolerance of the sealing gasket, external force during assembly, and insufficient friction. Summary of the invention

[0004] In order to improve the sealing performance of the cover, the present application provides a guide rail slider dustproof sealing cover, a guide rail slider and an assembly process of the two.

[0005] The present application provides a guide rail slider dustproof sealing cover adopts the following technical solution: A guide rail slider dustproof sealing cover, comprising a first sealing sheet and a second sealing sheet, the bottoms of the first sealing sheet and the second sealing sheet are connected by a connecting plate, the first sealing sheet is provided with a first bent portion on a side facing the guide rail, the second sealing sheet is provided with a second bent portion on a side facing the guide rail, an installation channel is reserved between the first bent portion and the second bent portion, a sealing strip is provided between the first sealing sheet and the second sealing sheet, the sealing strip extends from the installation channel and abuts against the outer peripheral surface of the rail; A sealing module is arranged between the first sealing sheet and the second sealing sheet, and an air injection chamber and an oil injection chamber are arranged in the sealing module. The sealing module is provided with an exhaust duct on a side facing the guide rail, and the exhaust duct is opened along the contour of the sealing module. The exhaust duct is connected with the air injection chamber, and the side of the sealing strip away from the guide rail extends into the exhaust duct. The first sealing sheet is provided with an oil inlet hole connected with the oil injection chamber.

[0006] By adopting the above technical solution, the sealing strip is placed between the first sealing sheet and the second sealing sheet, and then the sealing module is installed. The sealing module, the first sealing sheet and the second sealing sheet are fixed together on the guide rail slider. After the guide rail slider is installed on the guide rail, gas is injected into the gas injection chamber. As the gas pressure in the gas injection chamber continues to increase, the gas squeezes the sealing strip through the exhaust duct, so that the sealing strip fits against the guide rail to complete the sealing. Lubricating oil is stored in the oil injection chamber, which can be provided to the guide rail slider for lubrication.

[0007] This sealing method has strong adaptive adjustment ability. The air injection chamber can adjust the air pressure to make the sealing strip fit the rail surface better. Even if the rail is slightly worn or the surface is uneven, or there is a positioning tolerance during installation, or the bolt preload is different, the sealing strip can dynamically adjust its deformation, thus always maintaining a good sealing effect.

[0008] The adjustable pressure provided by the air injection chamber can not only solve the problem of different sealing requirements in different environments, but also prevent the sealing strip from wearing the guide rail surface due to over-tightening.

[0011] By adopting the above technical solution, since the guide rails are usually I-shaped or special-shaped, the overall module cannot be easily disassembled. The spliced ​​modular design can flexibly cope with guide rails of different shapes, so that the sealing block can be easily assembled from different directions. This not only improves the convenience of assembly, but also ensures that the sealing effect is more comprehensive and stable.

[0021] By adopting the above technical solution, the design of the first and second tightening bolts enables the dust strip to fit tightly against the side wall of the guide rail, thereby further improving the sealing effect. Through bolt adjustment, the tightness of the dust strip can be adjusted within a certain range, ensuring the long-term stability and dustproof effect of the sealing strip.

[0022] Optionally, the dustproof strip comprises an inserting portion, a first abutting portion and two second abutting portions, the inserting portion is located in the first inserting slot and the second inserting slot, the first abutting portion and the second abutting portion are integrally formed, the first abutting portion is located in the middle section of the inserting portion, one end of the first abutting portion away from the inserting portion abuts against a guide rail, and a space is left between the middle section of the first abutting portion and the guide rail; The second abutting portion is located at an end of the inserting portion, the second abutting portion is connected to the first abutting portion, and the second abutting portion is spliced ​​with the sealing strip and abuts against the guide rail.

[0023] By adopting the above technical solution, the design of the first abutment portion 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 extending the life of the dust strip and ensuring smooth movement of the guide rail slider.

The width of the connecting plate 3 is the same as that of the first sealing sheets 1 and the second sealing sheets 2. The two first sealing sheets 1 are connected by two lower mounting strips 4, and the lower mounting strips 4 are flush with the bottom of the connecting plate 3.

[0039] The first sealing sheet 1 is integrally formed with a first bent portion 11 on one side facing the guide rail, the second sealing sheet 2 is integrally formed with a second bent portion 21 on one side facing the guide rail, an installation channel 12 is reserved between the first bent portion 11 and the second bent portion 21, a sealing strip 13 is arranged between the first sealing sheet 1 and the second sealing sheet 2, the sealing strip 13 extends from the installation channel 12 and abuts against the outer peripheral surface of the rail; like Figure 2 , Figure 3 and Figure 4 A sealing module 5 is arranged between the first sealing sheet 1 and the second sealing sheet 2, and an air injection chamber 51 and an oil injection chamber 52 are arranged in the sealing module 5. The sealing module 5 is provided with an exhaust passage 53 on the side facing the guide rail. The exhaust passage 53 is opened along the contour of the sealing module 5, and the exhaust passage 53 is connected with the air injection chamber 51. The side of the sealing strip 13 away from the guide rail extends into the exhaust passage 53, and the first sealing sheet 1 is provided with an oil inlet hole 14 connected with the oil injection chamber 52.

[0040] The sealing module 5 includes two side sealing blocks 54 and an upper sealing block 55. A first guide bar 31 is integrally formed on the connecting plate 3. The first guide bar 31 is flush with the side of the connecting plate 3 away from the guide rail. A first guide groove 541 is formed 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 penetrates to the side of the side sealing block 54 away from and facing the guide rail. A second guide bar 542 is provided on the side of the side sealing block 54 facing the upper sealing block 55.

A second guide groove 551 is provided on the side of the upper sealing block 55 facing the side sealing block 54. The second guide groove 551 passes through to the side of the upper sealing block 55 facing away from and toward the guide rail (i.e., the top and bottom of the upper sealing block 55).

[0041] The two sides of the upper sealing block 55 are respectively spliced ​​with a side sealing block 54. The upper sealing block 55 is provided with a first air passage 552 on the side facing the guide rail, and the side sealing block 54 is provided with a second air passage 543 on the side facing the guide rail. The first air passage 552 and the second air passage 543 are connected to form an exhaust passage 53. A first air cavity 553 and a first oil cavity 554 are arranged in the upper sealing block 55, and a second air cavity 544 and a second oil cavity 545 are arranged in the side sealing block 54. The first air cavity 553 and the second air cavity 544 constitute an air injection chamber 51, and the first oil cavity 554 and the second oil cavity 545 constitute an oil injection chamber 52.

[0042] The first oil chamber 554 is closer to the first sealing sheet 1 than the first air chamber 553, and the second oil chamber 545 is closer to the first sealing sheet 1 than the second air chamber 544. The first air injection hole 555 and the first oil injection hole 556 are provided on the side of the upper sealing block 55 away from the guide rail (i.e., the top of the upper sealing block 55), and the second air injection hole 546 and the second oil injection hole 547 are provided on the side of the side sealing block 54 away from the guide rail. The first air injection hole 555 and the second air injection hole 546 are equipped with a one-way valve 548, and the first oil injection hole 556 and the second oil injection hole 547 are both covered with a sealing plug 549. The first sealing sheet 1 has three oil inlet holes 14, and 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 both connected to the corresponding oil inlet holes 14.

[0043] The side walls of the first sealing sheet 1, the side walls of the side sealing block 54, the side walls of the first guide strip 31 and the side walls of the second sealing block are commonly penetrated with a first fixing bolt 15, and the side walls of the first sealing sheet 1, the side walls of the upper sealing block 55 and the side walls of the second sealing sheet 2 are commonly penetrated with a second fixing bolt 22.

[0044] like Figure 2 and Figure 5 A first plug-in groove 41 is provided on the bottom surface of the lower mounting strip 4, and a second plug-in groove 32 is provided on the bottom surfaces of the first sealing sheet 1, the connecting plate 3 and the second sealing sheet 2. The first plug-in groove 41 is connected to the second plug-in groove 32, and a dustproof strip 6 is inserted into the first plug-in groove 41 and the second plug-in groove 32.

[0045] The dust strip 6 includes an inserting portion 61, a first abutting portion 62 and two second abutting portions 63. The length of the inserting portion 61 is equal to the total length of the first inserting slot 41 and the second inserting slot 32. The inserting portion 61 is located in the first inserting slot 41 and the second inserting slot 32. The first abutting portion 62 and the second abutting portion 63 are integrally formed. The first abutting portion 62 is located in the middle section of the inserting portion 61. One end of the first abutting portion 62 away from the inserting portion 61 abuts against the guide rail, and a space is left between the middle section of the first abutting portion 62 and the guide rail. The second abutting portion 63 is located at the end of the inserting portion 61 . The second abutting portion 63 is connected to the first abutting portion 62 . The second abutting portion 63 is spliced ​​with the sealing strip 13 and abuts against the guide rail.

[0046] The lower mounting bar 4 is threadedly connected with a first holding bolt 42 , and the connecting plate 3 is threadedly connected with a second holding bolt 33 . The first holding bolt 42 and the second holding bolt 33 penetrate from the side of the lower mounting bar 4 away from the guide rail and abut against the plug-in portion 61 .

[0047] Put the sealing strip 13 into the installation channel 12 between the first sealing sheet 1 and the second sealing sheet 2, then align the first guide groove 541 with the first guide strip 31, insert the side sealing block 54 between the first sealing sheet 1 and the second sealing sheet 2, then align the second guide groove 551 with the second guide strip 542, and insert the upper sealing block 55 between the first sealing sheet 1 and the second sealing sheet 2. Install the first fixing bolt 15 and the second fixing bolt 22, and thread the first fixing bolt 15 and the second fixing bolt 22 with the slider.

[0048] The connecting plate 3 is mounted on the slider, and then the dustproof strip 6 is installed, and the first tightening bolt 42 and the second tightening bolt 33 are adjusted to make the dustproof strip 6 fit the side wall of the guide rail.

[0049] After injecting lubricating oil into the first oil chamber 554 and the second oil chamber 545, cover the sealing plug 549, and then inject gas into the first air chamber 553 and the second air chamber 544. The gas squeezes the sealing strip 13 through the exhaust duct 53, so that the sealing strip 13 fits with the guide rail to complete the sealing.

[0050] This sealing method has strong adaptive adjustment capability. The air injection chamber 51 can adjust the air pressure to make the sealing strip 13 better fit the surface of the guide rail. Even if the guide rail is slightly worn or the surface is uneven, or there is a positioning tolerance during installation, and the bolt preload is different, the sealing strip 13 can dynamically adjust the deformation, thereby always maintaining a good sealing effect.

[0051] The adjustable pressure provided by the gas injection chamber 51 can not only solve the problem of different sealing requirements in different environments, but also prevent the sealing strip 13 from wearing the guide rail surface due to over-tightening.

[0052] Since the sealing strip 13 can be deformed and adapted by adjusting the air cavity, it can not only reduce the wear of the sealing strip 13 and the guide rail, but also extend the service life of the sealing strip 13 itself.

[0053] Furthermore, the dust strip 6 can seal the gap between the bottom surface of the guide rail slider and the guide rail, preventing dust and particulate matter from entering the interior of the guide rail slider from the bottom, effectively improving the operating stability and service life of the slider. At the same time, the design of the first abutment 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 and reduce wear, thereby extending the life of the dust strip 6 and ensuring smooth movement of the guide rail slider. The second abutment portion 63 is spliced ​​with the sealing strip 13 to seal the side and bottom of the end face of the guide rail slider, preventing dust from passing between the sealing strip 13 and the second abutment portion 63, further improving the sealing effect.

[0054] like Figure 6 and Figure 7 The embodiment of the present application further provides a guide rail slider, which is connected to the above-mentioned guide rail slider dustproof sealing cover, including a housing 7, the housing 7 is provided with two connection grooves 71 along its length direction, the lower mounting bar 4 is embedded in the connection groove 71 and adapted, three sliding channels 72 are provided at both ends of the housing 7, each sliding channel 72 is provided with a spring 73, the spring 73 is connected with an oil filling pipe 74, the oil filling pipe 74 facing the upper sealing block 55 corresponds to the first oil filling hole 556 one by one, and the oil filling pipe 74 facing the side sealing block 54 corresponds to the second oil filling hole 547 one by one. A guide surface 741 is provided on the circumference of one end of the oil filling pipe 74 away from the spring 73.

[0055] When the side seal block 54 and the upper seal block 55 are inserted into the first seal sheet 1 and the second seal sheet 2, the side seal block 54 and the upper seal block 55 will abut against the oil filling pipe 74 and extend into the sliding channel 72. When the side seal block 54 and the upper seal block 55 are installed in place, the oil filling pipe 74 is aligned with the first oil filling hole 556 and the second oil filling hole 547. At this time, the oil filling pipe 74 extends into the first oil chamber 554 and the second oil chamber 545 under the action of the spring 73, which plays a role in positioning and adjustment, and is convenient for assembly. The connecting groove 71 also plays a positioning role, ensuring that the first seal sheet 1 can face the guide rail slider, which is convenient for the next step of installation.
