[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] In related technologies, linear motor modules are important functional components in various machine tools, CNC machining centers, and precision electromechanical systems. Linear motors are used for linear transmission to ensure the functionality of the equipment. In linear motor modules, a return converter is assembled as a component to facilitate linear transmission. Currently, disassembling and assembling the return converter requires separating the slide table and slide rail, which is inconvenient and affects the maintenance efficiency of the linear motor module.
[0026] Please refer to Figure 1 As shown, an embodiment of this application provides a slide rail structure 100, which includes a slide rail component 110, a slide table 120, and a drive component 180.
[0027] refer to Figure 1 and Figure 2 As shown, the slide rail structure 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X refers to the length direction of the slide rail structure 100, i.e., the direction of movement of the slide table 120 in the slide rail structure 100; the second direction Y refers to the width direction of the slide rail structure 100; and the third direction Z refers to the height direction of the slide rail structure 100. It is understood that the above definitions are only for the convenience of understanding the relative positional relationships of the various parts in the slide rail structure 100 and should not be construed as limitations on this application.
[0028] Specifically, in combination Figure 2 and Figure 3 As shown, the slide table 120 includes a slide table body 121, a positioning component 130, and a return device 140. The slide table body 121 is provided with a mounting groove 1211 and a boss 1212 on the side near the slide rail component 110. The return device 140 includes an end cap assembly 141 and a plurality of balls 142. The end cap assembly 141 is detachably connected to the boss 1212, and the end cap assembly 141, the return device 140, and the boss 1212 together define a return channel. After the end cap assembly 141 and the boss 1212 are assembled and positioned, the return channel is defined. The boss 1212 can serve as the assembly space for the return device 140. The structure is relatively compact and the space utilization rate is high.
[0029] In this embodiment, the positioning member 130 is positioned on the side of the end cap assembly 141 opposite to the boss 1212. A plurality of balls 142 are disposed in the return channel, with at least a portion of the balls 142 abutting against the slide rail 110, so that the slide table 120 is slidably connected to the slide rail 110. The driving member 180 is embedded in the mounting groove 1211 to drive the slide table 120 to reciprocate on the slide rail 110. Correspondingly, the driving member 180 is used to drive the slide table 120 to reciprocate on the slide rail 110. The driving member 180 can be a drive motor. The drive motor can be glued and fixed to the mounting groove 1211 of the slide body 121. The drive component 180 is embedded in the mounting groove 1211 of the slide body 121. The drive component 180 is used to drive the slide 120 to reciprocate so that multiple balls 142 can roll in the return channel, so that the balls 142 of the return device 140 abut against the slide rail component 110 to reduce the friction of the slide 120 during the sliding process and reduce the wear of the slide 120. The end cap assembly 141 can be removed from the boss 1212 of the slide 120, which facilitates the independent disassembly and maintenance of the return device 140 and has better disassembly and assembly convenience.
[0030] As is easily understood, the return device 140 typically refers to the device that guides the balls 142 to circulate within the bearing, ensuring that the rolling elements can return from the load area to the unload area during movement, forming a continuous cycle. The balls 142 roll on the slide rail 110, reducing friction on the slide table 120 during sliding, thereby reducing wear on the slide table 120 and extending its service life. The balls 142 can be steel balls.
[0031] For example, such as Figure 2 As shown, there are two return valves 140 and two bosses 1212. One return valve 140 corresponds to one boss 1212. The slide rail 110 can be an embedded grooved guide rail. Two grooved guide rails are provided on the inner side wall of the slide rail 110. The grooved guide rails are used to slide and connect the return valve 140.
[0032] In addition, the return valve 140 plays a supporting and guiding role. The return valve 140 is guided by rolling. The balls 142 roll and circulate infinitely between the slide body 121 and the slide rail 110, so that the slide 120 makes linear reciprocating motion along the guide rail and greatly reduces the coefficient of friction, thus achieving high mechanical precision.
[0033] In one embodiment, alternatively, referencing Figure 3As shown, the reflux device 140 further includes a first reflux guide rail 143 and a reflux pipe 144. The ball bearing 142 can move between the first reflux guide rail 143 and the reflux pipe 144. The reflux pipe 144 passes through the boss 1212. The first reflux guide rail 143 is embedded in the groove of the boss 1212 and is arranged opposite to the slide rail 110 along the first direction X. The ball bearing 142 can roll between the first reflux guide rail 143 and the reflux pipe 144 to form a circulating rolling path, so as to facilitate the transmission and rotation of the ball bearing 142. When the ball bearing 142 moves to the first reflux guide rail 143, the ball bearing 142 abuts against the slide rail 110 to realize the relative movement between the reflux device 140 and the slide rail 110.
[0034] In one embodiment, alternatively, referencing Figure 3 and Figure 4 As shown, the end cap assembly 141 includes an end cap 1411 and a connector 1412. The end cap 1411 is inserted into the end opening of the boss 1212. The connector 1412 abuts between the boss 1212 and the end cap 1411. The connector 1412 is connected to the boss 1212. The end cap 1411 is assembled and positioned with the boss 1212 through the connector 1412. The boss 1212 can define a return channel for the rolling ball 142.
[0035] Optionally, combined Figure 3 and Figure 4 As shown, the slide rail structure 100 also includes a buffer 150, which is disposed on the limiting step 1213. The buffer 150 abuts between the end cap assembly 141 and the positioning member 130. The buffer 150 is used to buffer the end cap assembly 141. The buffer 150 can be a rubber pad or a silicone pad, which has better elasticity and buffering performance.
[0036] In summary, the drive component 180 of the slide rail structure 100 is used to drive the slide table 120 to reciprocate on the slide rail component 110. After the end cap assembly 141 and the boss 1212 are assembled and positioned, a return channel is defined. The boss 1212 can serve as the assembly space for the return device 140. The drive component 180 is embedded in the mounting groove 1211 of the slide table body 121. The drive component 180 is used to drive the slide table 120 to reciprocate. The structure is relatively compact and has a high space utilization rate, so that multiple balls 142 can roll in the return channel. This allows the balls 142 of the return device 140 to abut against the slide rail component 110, reducing the friction of the slide table 120 during the sliding process and reducing the wear of the slide table 120. The end cap assembly 141 can be removed from the boss 1212 of the slide table 120, which facilitates the independent disassembly and maintenance of the return device 140. It has better disassembly and assembly convenience, thereby improving the maintenance efficiency of the linear motor module.
[0037] refer to Figure 1 As shown, an embodiment of this application provides another slide rail structure 100, which includes a slide rail 110, a slide table 120, and a drive member 180.
[0038] Specifically, in combination Figure 2 and Figure 3 As shown, the slide table 120 includes a slide table body 121, a positioning member 130, and a return device 140. The slide table body 121 has a mounting groove 1211 and a boss 1212 on the side near the slide rail member 110. The return device 140 includes an end cap assembly 141 and a plurality of balls 142. The end cap assembly 141 is detachably connected to the boss 1212, and the end cap assembly 141, the return device 140, and the boss 1212 together form a common structure. A return channel is defined, and the positioning member 130 is positioned on the side of the end cap assembly 141 opposite to the boss 1212. A plurality of balls 142 are disposed in the return channel, with at least a portion of the balls 142 abutting against the slide rail 110, so that the slide table 120 is slidably connected to the slide rail 110. The driving member 180 is embedded in the mounting groove 1211 to drive the slide table 120 to reciprocate on the slide rail 110. Correspondingly, the drive component 180 is used to drive the slide table 120 to reciprocate on the slide rail component 110. The drive component 180 can be a drive motor, which can be glued and fixed to the mounting groove 1211 of the slide table body 121. After the end cap assembly 141 and the boss 1212 are assembled and positioned, a return channel is defined. The boss 1212 can serve as the assembly space for the return device 140. The drive component 180 is embedded in the mounting groove 1211 of the slide table body 121. The drive component 180 is used to drive the slide table 120 to reciprocate on the slide rail component 110. The drive slide 120 reciprocates, with a compact structure and high space utilization, so that multiple balls 142 can roll in the return channel, allowing the balls 142 of the return device 140 to abut against the slide rail 110 to reduce the friction of the slide 120 during the sliding process and reduce the wear of the slide 120. The end cover assembly 141 can be removed from the boss 1212 of the slide 120, which facilitates the independent disassembly and maintenance of the return device 140 and has good disassembly and assembly convenience.
[0039] For example, the slide rail structure 100 also includes a cover plate 170, which is arranged parallel to the slide rail component 110 along the first direction X. The cover plate 170 is located at the end of the slide body 121 away from the slide rail component 110. There is a gap between the slide body 121 and the cover plate 170 to avoid the cover plate 170 from obstructing or causing friction on the relative movement of the slide body 121. The cover plate 170 is received in the groove of the slide body 121 and plays a certain role in regulating and protecting the slide body 121.
[0040] In one embodiment, alternatively, referencing Figure 3 As shown, the reflux device 140 further includes a first reflux guide rail 143 and a reflux pipe 144. The ball bearing 142 can move between the first reflux guide rail 143 and the reflux pipe 144. The reflux pipe 144 passes through the boss 1212. The first reflux guide rail 143 is embedded in the groove of the boss 1212 and is arranged opposite to the slide rail 110 along the first direction X. The ball bearing 142 can roll between the first reflux guide rail 143 and the reflux pipe 144 to form a circulating rolling path, so as to facilitate the transmission and rotation of the ball bearing 142. When the ball bearing 142 moves to the first reflux guide rail 143, the ball bearing 142 abuts against the slide rail 110 to realize the relative movement between the reflux device 140 and the slide rail 110. For example, the first reflux guide rail 143 and the reflux pipe 144 are arranged parallel to each other.
[0041] In one embodiment, alternatively, referencing Figure 3 and Figure 4 As shown, the end cap assembly 141 includes an end cap 1411 and a connector 1412. The end cap 1411 is inserted into the end opening of the boss 1212. The connector 1412 abuts between the boss 1212 and the end cap 1411. The connector 1412 is connected to the boss 1212. The end cap 1411 is assembled and positioned with the boss 1212 through the connector 1412. The boss 1212 contains a return channel for the rolling of the ball 142.
[0042] The number of end cap assemblies 141 is multiple, with each pair of end cap assemblies 141 corresponding to a boss 1212. The end cap assemblies 141 are arranged at opposite ends of the boss 1212 along the first direction X, so as to reduce the size of the return valve 140, making the structural components highly integrated and the space more compact.
[0043] For example, such as Figure 4 and Figure 5 As shown, the end cap 1411 is provided with a slot 1413, and the connector 1412 is provided with a snap-fit part 1414. When the end cap 1411 is connected to the connector 1412, the snap-fit part 1414 snaps into the slot 1413. The slot 1413 is used to limit the movement of the snap-fit part 1414 along the second direction Y. The second direction Y is perpendicular to the first direction X. The snap-fit part 1414 of the connector 1412 and the slot 1413 of the end cap 1411 can form a snap-fit structure. The snap-fit structure can limit the movement of the end cap 1411 and the connector 1412 along the second direction Y, so that the slot 1413 of the end cap 1411 can separate from the snap-fit part 1414 of the connector 1412 when it moves along the first direction X, thereby realizing the disassembly and assembly of the end cap 1411 and having a better technical effect.
[0044] Further, refer to Figure 4 and Figure 5 As shown, the end cap 1411 is provided with a second return guide rail 1411a, and the connector 1412 is provided with a third return guide rail 1412a. The third return guide rail 1412a is connected to the first return guide rail 143 and the return pipe 144 respectively. The second return guide rail 1411a and the third return guide rail 1412a are arranged opposite to each other and together form a curved structure. The second return guide rail 1411a and the third return guide rail 1412a are used to regulate and guide the rolling path of the ball 142. The second return guide rail 1411a and the third return guide rail 1412a can limit the pipe forming the curved structure, prevent the ball 142 from coming out of the return channel, and keep the ball 142 always within the return channel.
[0045] Optionally, such as Figure 4 As shown, the end cap 1411 is provided with a first oil filling hole 1411b, which is connected to the return channel. The positioning member 130 is provided with a second oil filling hole 131 and a sealing member 132. The first oil filling hole 1411b is provided corresponding to the second oil filling hole 131, so that the sealing member 132 passes through the first oil filling hole 1411b and the second oil filling hole 131 in sequence. The user can pass through the first oil filling hole 1411b and the second oil filling hole 131. Lubricating oil and grease are injected into the end cap 1411 of the return valve 140. After the lubricating oil and grease are added, the first oil injection hole 1411b and the second oil injection hole 131 are sealed by the sealing member 132. The sealing member 132 can be used to seal the bolts to prevent the lubricating oil from overflowing and leaking. The end cap 1411 is used to store lubricating oil and grease for long-term lubrication. When the ball bearing 142 passes through the end cap 1411, the lubricating oil and grease can adhere to it, which improves the lubrication effect on the ball bearing 142.
[0046] In one embodiment, alternatively, referencing Figure 4 As shown, the slide body 121 is provided with a limiting step 1213. The positioning member 130 is connected to the slide body 121 and is located on the limiting step 1213. The end cap assembly 141 is disposed between the positioning member 130 and the boss 1212. The positioning member 130 is assembled and positioned at the position of the limiting step 1213. The positioning member 130 abuts against the end cap assembly 141 and plays a limiting role on the end cap assembly 141. The end cap assembly 141 is limited and fixed by the positioning member 130 and the boss 1212 to ensure the installation stability of the end cap assembly 141.
[0047] Optionally, combined Figure 3 and Figure 4As shown, the slide rail structure 100 also includes a buffer 150, which is disposed on the limiting step 1213. The buffer 150 abuts between the end cap assembly 141 and the positioning member 130. The buffer 150 is used to buffer the end cap assembly 141. The buffer 150 can be a rubber pad or a silicone pad, which has better elasticity and buffering performance.
[0048] In one embodiment, alternatively, referencing Figure 1 As shown, the slide rail structure 100 also includes an encoder 160, which is mounted on one side of the slide body 121. The slide body 121 can drive the encoder 160 to move relative to it. The encoder 160 is a sensor that converts physical quantities such as mechanical displacement, angle, or speed into electrical signals. In this application, the encoder 160 is used in the slide rail structure 100 to detect the position, speed, and direction of movement of the slide body 121, ensuring motion accuracy and stability. It can be understood that the encoder 160 obtains the instantaneous speed and direction of movement of the slider through the pulse signal frequency or signal phase difference, which is used to adjust the output torque of the drive motor. The encoder 160 can also monitor abnormal signals (such as sudden stop or jitter), triggering system alarms or protection mechanisms to prevent equipment damage. Specifically, the encoder 160 can be an optical encoder 160.
[0049] An embodiment of this utility model also provides a linear motor module, including the slide rail structure 100 described in any of the above embodiments. The linear motor module including the slide rail structure 100 has all the beneficial effects of the slide rail structure 100, which will not be described in detail here.
