[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0033] Please refer to Figures 1 to 4 In the embodiments of the present application, a linear slider for lean pipe assembly includes a slider body 33, the slider body 33 is provided with a sliding part 10 located at the inner side and a sleeve part 20 located at the outer side, the sleeve part 20 is sleeved on the sliding part 10 and forms a fixed connection; the sliding part 10 is used for slidingly connecting the fixed optical axis 31 of the lean pipe, the outer side wall of the sleeve part 20 is provided with a dovetail strip 21, which is used for connecting the movable assembly 32 of the lean pipe, so that the movable assembly 32 can move linearly along the fixed optical axis 31.

[0034] Specifically, since the outer ring of the conventional linear bearing is not provided with a connecting piece, the bearing is usually fixed on a machine or a structure by using a mounting hole, a thread or a flange connection on the mounting device, which is not convenient for the rapid assembly of the lean pipe workbench 30 system, increases the size of the connecting part of the linear bearing, and is not suitable for the simplified setting of the lean pipe workbench 30, so it is necessary to improve.

[0035] Secondly, by providing the dovetail strip 21 on the outer side wall of the sleeve piece 20, the rapid assembly of the lean pipe lifting system is realized, and the corresponding lifting movement of the material / tool is realized, thereby improving the production efficiency. Therefore, the improved linear sliding table not only can accelerate the assembly efficiency, but also can reduce the size of the connecting part, meet the simplified structure of the lean pipe workbench 30, better connect with other industry accessories of the lean pipe, and internally provide the sliding piece 10, which can realize linear sliding, has good performance, good stability and long service life.

[0036] Preferably, the sleeve piece 20 and the sliding piece 10 are fixedly connected in an interference fit connection mode. Alternatively, the sleeve piece 20 and the sliding piece 10 are fixedly connected in a threaded connection mode. Alternatively, the sleeve piece 20 and the sliding piece 10 are fixedly connected in a key connection mode.

[0037] Specifically, the sleeve piece 20 and the sliding piece 10 can be fixedly connected in various connection modes in the prior art, so that the sleeve piece 20 and the sliding piece 10 form an integral part and cannot move relative to each other.

[0038] As shown in Figure 1 and Figure 3 Preferably, the sleeve piece 20 is provided with a retaining ring groove 24, the retaining ring groove 24 is arranged on the inner side wall of the sleeve piece 20 close to both ends of the sliding piece 10, and a shaft retaining ring 25 is arranged in the retaining ring groove 24, so as to fix the sliding piece 10.

[0039] Specifically, the shaft retaining ring 25 and the retaining ring groove 24 cooperate with each other to fix the sliding piece 10 in the axial direction, so as to prevent the axial movement of the sliding piece 10. The sleeve piece 20 is provided with the retaining ring groove 24, and the shaft retaining ring 25 is placed in the groove, which can prevent the movement of the sliding piece 10 in the axial direction, thereby effectively avoiding the axial movement of the sliding piece 10 caused by vibration or external force. Alternatively, to avoid the axial movement of the linear bearing during use, the two sides of the sliding piece 10 are provided with fixing rings, which are fixedly connected with the inner wall of the sleeve piece 20.

[0040] Preferably, the sliding member 10 is provided as a sliding bushing and is made of a copper alloy material or a polyformal material. Specifically, the sliding bushing can be made of a copper alloy sleeve, such as an oil bronze bushing (e.g., SAE841 material), which forms a microporous oil storage structure through a sintering process, commonly known as a graphite copper sleeve or a self-lubricating copper sleeve. The sliding bushing can also be made of polyformal (POM), also known as acetal resin, polyoxymethylene, and polyacetal, which is a thermoplastic crystalline polymer known as "super steel" or "race steel". It has good wear resistance and self-lubricating properties, which can reduce friction.

[0041] As shown in Figure 3 , preferably, the sliding member 10 is provided as a linear bearing. Specifically, in order to obtain smaller frictional resistance and higher running accuracy, the existing linear bearing can also be directly used as the sliding member 10, which has the characteristics of small friction and stable sliding, does not change with the speed of the bearing, and can obtain high sensitivity, high precision and smooth linear motion.

[0042] As shown in Figures 1 to 3 , preferably, a plurality of dovetail strips 21 are uniformly distributed in the circumferential direction of the sleeve member 20, thereby connecting a plurality of external movable components 32.

[0043] Specifically, in the circumferential direction of the sleeve member 20, preferably, four groups of dovetail strips 21 are uniformly distributed, thereby connecting four groups of external components, and the corresponding external components can be assembled at an angle of 90 degrees, which can not only solve the installation problem, but also expand more functions, such as installing various lean pipe parts through the dovetail strips 21 to realize the derivation of functions.

[0044] As shown in Figure 2 , preferably, the two sides of the dovetail strip 21 are respectively provided with a buckling edge 22, and the buckling edge 22 and the outer wall of the sleeve member 20 form an angle less than 90 degrees.

[0045] Specifically, the buckling edge 22 is inclined to the side wall of the sleeve member 20 at a certain angle to form an angle less than 90 degrees, so that the buckling edge 22 can fix the external movable component 32, so that the linear sliding block can conveniently connect the external movable component 32, optimize the overall assembly structure of the lean pipe, and facilitate the linear driving of the movable component 32.

[0046] Secondly, the position of the external movable component 32 connected to the dovetail strip 21 can also be provided with a corresponding dovetail groove, which cooperates with the dovetail strip 21 to realize the rapid assembly of the production platform of the lean pipe system.

[0047] As shown in Figure 1 and Figure 2 , preferably, the dovetail strip 21 and the inner side wall of the sleeve member 20 are provided with an empty slot 23 for passing through a cable.

[0048] Specifically, since more cables may be needed during the assembly and use of the lean pipe, the cable can be threaded through the empty slot 23, optimizing the arrangement of the cable and preventing the cable from winding.

[0049] Secondly, the empty slot 23 can be formed by cutting process during production, or can be formed by forging process from the inside of the sleeve piece 20 to the outside. For example, when the dovetail strip 21 is formed by forging, the empty slot 23 can be formed at the same time. Specific embodiment one

[0051] Structure: A linear slide for lean pipe assembly is composed of an inner sliding piece 10 and an outer sleeve piece 20.

The external component is assembled at an angle of 90 degrees, for example, connecting various parts of the lean pipe, realizing the lifting movement of materials / fittings, and improving production efficiency. At the same time, the empty slot 23 between the dovetail strip 21 and the inner sidewall of the sleeve piece 20 can be used to thread the cable, optimize the cable arrangement, and prevent winding.

The clamping edges 22 on both sides of the dovetail strips 21 are at an angle of less than 90 degrees with the outer wall of the sleeve piece 20, facilitating the fixation of the external movable assembly 32. The inner wall of the sleeve piece 20 is provided with a retaining ring groove 24 and a shaft retaining ring 25 for fixing the sliding piece 10.

[0057] Application scenario: suitable for lean pipe workbenches 30 with high requirements for motion accuracy, the external movable assembly 32 is connected through the dovetail strips 21, which can expand more functions, such as the installation of various connecting rods and other accessories that need to be moved. The clearance groove 23 can effectively organize the cables in the system, making the overall structure more concise and orderly.

[0058] Example three

[0059] Structural composition: the linear slide is composed of an inner sliding piece 10 and an outer sleeve piece 20. The sliding piece 10 adopts a sliding bushing made of polyoxymethylene (POM) material, which has good wear resistance and self-lubricating properties, and can reduce friction.

[0060] Key component design: the outer wall of the sleeve piece 20 is provided with dovetail strips 21, which are also evenly distributed in the circumferential direction. The clamping edges 22 on both sides of the dovetail strips 21 are at an angle of less than 90 degrees with the outer wall of the sleeve piece 20. The retaining ring groove 24 is arranged on the inner wall of the sleeve piece 20, and the shaft retaining ring 25 is used to fix the sliding piece 10.

[0061] Application scenario: suitable for lean pipe production platforms with strict cost control and relatively low accuracy requirements, the simple movable assembly 32 such as a material tray is connected through the dovetail strips 21, realizing the linear conveying of materials. The clearance groove 23 can be used to pass through simple control lines to meet the basic production needs.

[0062] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
