Description

Technical Field

[0001] This application relates to the field of linear modules, and more particularly to a sliding device and a linear module. Background Technology

[0002] Linear motor modules, as core components in the field of precision transmission, play a crucial role in high-end manufacturing equipment and automation systems. With the development of industrial technology, their load performance requirements are increasingly demanding. Traditional linear modules typically rely on a single layer of rolling elements for support and guidance, a structure that can meet basic motion requirements under normal operating conditions. However, as equipment evolves towards higher loads and higher rigidity, the number of effective load-bearing points is strictly limited by the module width because the rolling elements can only be arranged in a single layer laterally along the guide rail. To increase the module's load capacity, the lateral dimensions of the guide rail and the module must be increased, directly leading to an increase in the width of the entire motion unit.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] Existing linear module sliders typically have only one rolling channel. To increase the slider's load capacity, the channels for the balls need to be connected to the outside on both sides, allowing the balls to engage with the base of the linear module. Therefore, to enable the base of the linear module to engage with the balls on the other side of the slider, the lateral dimension of the base needs to be increased, and a groove adapted to the slider needs to be created to accommodate it, allowing the balls on both sides of the slider to engage with the side walls of the groove. This increases the lateral dimension of the base to improve the slider's load capacity, which is unsuitable for use in environments with limited space. Therefore, this application provides a sliding device to solve the above problems.

[0025] This application provides a sliding device with a first direction Z. The sliding device includes a slider body 100, which has a first rolling channel 101 and at least one second rolling channel 102. The first rolling channel 101 and the second rolling channel 102 are both partially connected to the outside of the slider body 100 and are spaced apart along the first direction Z. Rollers 103 are provided in both the first rolling channel 101 and the second rolling channel 102. The slider body 100 has a first oil passage 104 and a second oil passage 105 on one side along the first direction Z. The first oil passage 104 is connected to the first rolling channel 101, and the second oil passage 105 is connected to the second rolling channel 102.

[0026] Please see Figure 1 and Figure 2 As shown, in order to increase the load capacity of the entire slider body 100, multiple layers of rollers 103 are provided in the slider body 100. To this end, a first rolling channel 101 and at least one second rolling channel 102 need to be opened in the slider body 100 along the first direction Z, and rollers 103 are provided in both the first rolling channel 101 and the second rolling channel 102. The parts of the first rolling channel 101 and the second rolling channel 102 that communicate with the outside are located on the same side of the slider body 100. The openings of the first rolling channel 101 and the second rolling channel 102 that communicate with the outside are located on the same side and only one side communicates with the outside. Thus, the slider body 100 is connected to the base 200 on one side through multiple layers of rollers 103, thereby realizing the ability to increase the load capacity of the slider body 100 by using multiple layers of rollers 103.

[0027] It is understood that this application sets up different numbers of second rolling channels 102 on the basis of setting up the first rolling channel 101, so as to accommodate different numbers of layers of rollers 103, so that the multi-layer rollers 103 on one side of the slider body 100 cooperate with the base 200. Only the height of the slider body 100 needs to be increased, so that the lateral distance of the base 200 is not increased while meeting the load requirements.

[0028] Please continue reading. Figure 1 and Figure 2As shown, in this embodiment, the first rolling channel 101 and the second rolling channel 102 are both U-shaped, and the opening of the U-shape is the position where the first rolling channel 101 and the second rolling channel 102 communicate with the outside of the slider body 100.

[0029] In one embodiment, the rollers 103 of each layer are arranged in a square shape, so that the rollers 103 can circulate along their trajectory in the first rolling channel 101 and the second rolling channel 102, thereby causing the slider body 100 to move relative to the base 200.

[0030] Furthermore, in order to prevent the roller 103 from failing to roll or getting stuck due to friction in the first rolling channel 101 and the second rolling channel 102, a first oil passage 104 connected to the first rolling channel 101 and a second oil passage 105 connected to the second rolling channel 102 are also connected to the slider body 100. The first oil passage 104 provides lubricating oil to the roller 103 in the first rolling channel 101, and the second oil passage 105 provides lubricating oil to the roller 103 in the second rolling channel 102.

[0031] For example, roller 103 is a steel ball.

[0032] In some embodiments, the slider body 100 includes a first fixing block 110 and at least one second fixing block 120 stacked sequentially. The first fixing block 110 has a first receiving groove 111 on its side facing the second fixing block 120, and the second fixing block 120 has a second receiving groove 121 corresponding to the first receiving groove 111 on its side facing the first fixing block 110. The first fixing block 110 and the second fixing block 120 cooperate to form a first rolling channel 101 with the first receiving groove 111 and the second receiving groove 121.

[0033] Please see Figure 2 , Figure 3 as well as Figure 4 As shown, to facilitate the processing and formation of the first rolling channel 101, the first rolling channel 101 can be divided into a first receiving groove 111 and a second receiving groove 121, which are then spliced ​​together. Correspondingly, the entire slider body 100 also has multiple fixed components. Specifically, the first receiving groove 111 is opened on the side of the first fixing block 110 facing the second fixing block 120, and the second receiving groove 121 is opened on the side of the second fixing block 120 facing the first fixing block 110. After the first fixing block 110 and the second fixing block 120 are engaged, the first receiving groove 111 and the second receiving groove 121 will automatically splice together to form the first rolling channel 101. It should be noted that the first receiving groove 111 and the second receiving groove 121 are both semi-circular grooves. It can be understood that the first rolling channel 101 formed by splicing the first receiving groove 111 and the second receiving groove 121 is a circular hole.

[0034] In some embodiments, the first fixing block 110 has a first oil inlet hole 113 on its side away from the second fixing block 120 to form a first oil passage 104, and the first oil inlet hole 113 is connected to the first receiving groove 111.

[0035] See Figure 2 and Figure 3 As shown, the first fixing block 110 is located above the second fixing block 120. In order to allow lubricating oil to enter the first rolling channel 101, a first oil inlet hole 113 communicating with the first receiving groove 111 is opened on the first fixing block 110 as a first oil passage 104. Lubricating oil is delivered to the first receiving groove 111 through the first oil inlet hole 113 to achieve the function of lubricating the rollers 103 located in the first rolling channel 101.

[0036] In some embodiments, the slider body 100 further includes a third fixing block 130, the third fixing block 130 being located on the side of the second receiving groove 121 away from the first fixing block 110, the second fixing block 120 having a third receiving groove 122 on the side facing the third fixing block 130, and the third fixing block 130 having a fourth receiving groove 131 corresponding to the second receiving groove 121 on the side facing the second fixing block 120, the second fixing block 120 and the third fixing block 130 cooperating to form a second rolling channel 102 by the third receiving groove 122 and the fourth receiving groove 131.

[0037] See Figure 2 , Figure 5 as well as Figure 6 As shown, in one embodiment, there is one second fixing block 120, and a second rolling channel 102 is formed between the second fixing block 120 and the third fixing block 130. Correspondingly, in order to facilitate the processing of the second rolling channel 102, the slider body 100 also includes a third fixing block 130 that cooperates with and connects to the second fixing block 120. Specifically, the third fixing block 130 has a fourth receiving groove 131 on the side facing the second fixing block 120, and the second fixing block 120 has a third receiving groove 122 on the side facing the third fixing block 130. After the second fixing block 120 and the third fixing block 130 are connected, the third receiving groove 122 and the fourth receiving groove 131 are also spliced ​​to form the second rolling channel 102.

[0038] In this embodiment, both the third receiving groove 122 and the fourth receiving groove 131 are semi-circular grooves, and the second rolling channel 102 formed by splicing the third receiving groove 122 and the fourth receiving groove 131 is a circular hole.

[0039] In another embodiment, when the number of second fixing blocks 120 is greater than or equal to 2, two adjacent second fixing blocks 120 cooperate to form a second rolling channel 102 by cooperating the second receiving groove 121 and the third receiving groove 122.

[0040] In order to lubricate the roller 103 located in the second oil passage 105, corresponding holes need to be made in the first fixing block 110 and the second fixing block 120 to deliver lubricating oil to the second oil passage 105.

[0041] In some embodiments, the first fixing block 110 has a second oil inlet hole 114 through the first fixing block 110 on the side opposite to the second fixing block 120, and the second fixing block 120 has a first oil passage hole 123 corresponding to the second oil inlet hole 114 on the side facing the first fixing block 110. The first oil passage hole 123 communicates with the third receiving groove 122, and the first oil passage hole 123 communicates with the second oil inlet hole 114 to form a second oil passage 105.

[0042] See Figure 2 , Figure 3 as well as Figure 4 As shown, a second oil inlet hole 114 is opened on the first fixed block 110 as an oil inlet section, and a first oil passage hole 123 is opened on the second fixed block 120 along the first direction Z as an oil delivery section. Specifically, after the first fixed block 110 and the second fixed block 120 are engaged, the second oil inlet hole 114 and the first oil passage hole 123 are connected to form a second oil passage 105. The external lubricating oil is delivered to the second rolling channel 102 through the second oil passage 105 to lubricate the internal rollers 103 and prevent jamming and poor operation.

[0043] In some embodiments, the first rolling channel 101 communicates with the outside of the slider body 100 to form two first openings 1011. A first limiting block 112 is provided on the side of the slider body 100 near the first opening 1011, and a first guide surface 1121 is provided on the side of the first limiting block 112 facing the first opening 1011. The second rolling channel 102 communicates with the outside of the slider body 100 to form two second openings 1021. A second limiting block 132 is provided on the side of the slider body 100 near the second opening 1021, and a second guide surface 1321 is provided on the side of the second limiting block 132 facing the second opening 1021.

[0044] See Figure 1 and Figure 2As shown, since the rollers 103 in the first rolling channel 101 and the second rolling channel 102 need to circulate back and forth within their tracks, specifically, in order to enable the rollers 103 to move between the two first openings 1011, a first limiting block 112 is provided on the first fixing block 110 at the position of each first opening 1011, and a first guide surface 1121 is provided on the first limiting block 112 facing the opening position, so that the rollers 103 at the position of the first opening 1011 can move through the first guide surface 1121. Specifically, the second opening 1021 is an inclined surface; similarly, the roller 103 in the second rolling channel 102 also needs to move between the two second openings 1021, that is, move from one position of the second opening 1021 to another position of the second opening 1021. Similarly, the third fixing block 130 at the position of the second opening 1021 is provided with a second limiting block 132, and the second limiting block 132 is provided with a second guide surface 1321 to guide the roller 103. The second guide surface 1321 is an inclined surface.

[0045] In some embodiments, the first fixing block 110 has a first recessed platform 1111 on its side facing the second fixing block 120, and the first recessed platform 1111 is located in the edge region of the first receiving groove 111. The second fixing block 120 has a first protrusion 1211 on its side facing the first fixing block 110, and the first protrusion 1211 is located in the edge region of the second receiving groove 121. The first protrusion 1211 and the first recessed platform 1111 are connected in cooperation. The third fixing block 130 has a second recessed platform 1311 on its side facing the second fixing block 120, and the second recessed platform 1311 is located in the edge region of the fourth receiving groove 131. The second fixing block 120 has a second protrusion 1221 on its side facing the third fixing block 130, and the second protrusion 1221 is located in the edge region of the third receiving groove 122. The second protrusion 1221 and the second recessed platform 1311 are connected in cooperation.

[0046] See Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, in order to prevent misalignment after the first fixing block 110 and the second fixing block 120 are engaged and to ensure that the first receiving groove 111 and the second receiving groove 121 are accurately joined to form the first rolling channel 101, a first recessed platform 1111 is provided on the side of the first fixing block 110 facing the second fixing block 120, and a first protrusion 1211 is provided on the side of the second fixing block 120 facing the first fixing block 110. When the first fixing block 110 and the second fixing block 120 are engaged and connected, the first protrusion 1211 will extend into the first recessed platform 1111 to achieve engagement and positioning. Correspondingly, when the second fixing block 120 and the third fixing block 130 are engaged and connected, the second protrusion 1221 of the second fixing block 120 will also extend into the second recessed platform 1311 of the third fixing block 130 to achieve engagement and positioning.

[0047] See Figure 7 and Figure 8 As shown, this embodiment also provides a linear module with a first direction Z and a second direction Y arranged perpendicularly to each other, including a sliding device, a base 200, a magnetic rail 300, a slide table 400, and a mover 500 as described above; the base 200 has multiple sliding grooves 201 spaced apart along the first direction Z on both sides, and the sliding grooves 201 are connected to the rollers 103; the magnetic rail 300 is arranged along the first direction Z on one side of the base 200; the slide table 400 is arranged on one side of the base 200, and the sliding device is arranged on the side of the slide table 400 facing the base 200. The sliding device is arranged on both sides of the slide table 400 along the second direction Y, and the slide table 400 is slidably connected to the base 200 through the sliding device; the mover 500 is arranged on the side of the slide table 400 facing the base 200.

[0048] See Figure 8 As shown, the number of grooves 201 along the first direction Z is the same as the number of layers of rollers 103. Correspondingly, rollers 103 cooperate with grooves 201, and the slider body 100 of the sliding device is connected to the slide table 400, thereby realizing that the slide table 400 slides relative to the base 200 through the sliding device.

[0049] In some embodiments, in order to provide lubricating oil to the rollers 103 of each layer, an oil supply channel 410 is provided in the slide table 400 to provide lubrication to the rollers 103 in each slider body 100.

[0050] The slide table 400 is provided with an oil supply channel 410 connected to the sliding device. The oil supply channel 410 includes a third oil inlet hole 411 and a second oil outlet hole 412 that are interconnected. The third oil inlet hole 411 is connected to the outside of the slide table 400. The second oil outlet hole 412 is provided with a first oil outlet hole 413 and a second oil outlet hole 414 along the first direction Z. The first oil outlet hole 413 is connected to the first oil passage 104, and the second oil outlet hole 414 is connected to the second oil passage 105.

[0051] See Figure 8 and Figure 9 As shown, the slider body 100 is fixedly installed on the slide table 400. It stores lubricating oil through the passage of the third oil inlet hole 411 and the second oil outlet hole 412. When the slide table 400 moves, the lubricating oil inside it flows through the first oil outlet hole 413 to the first oil passage 104 to lubricate the roller 103 in the first rolling passage 101. The lubricating oil flows through the second oil outlet hole 414 to the second oil passage 105 to lubricate the roller 103 in the second rolling passage 102, thereby providing lubricating oil for the roller 103.
