Description
Technical Field
[0001] This application relates to the field of linear module technology, and more specifically, to a linear module and a pre-pressure adjustment device. Background Technology
[0002] As a core transmission component in industrial automation equipment, the performance of linear modules directly affects the operating accuracy, stability, and service life of the equipment. In the design of linear modules, the preload between the slider and the guide rail is a crucial technical parameter. Preload eliminates the gap between the guide rail and the slider, thereby improving the system's rigidity and operational stability. In traditional linear modules, the preload is usually set at the factory. However, when the linear module experiences wear due to load variations, temperature fluctuations, or long-term use during actual operation, the original preload becomes inapplicable. Utility Model Content
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a linear module that can adjust the pre-pressure at any time.
[0004] This application also provides a pre-pressure regulating device.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, this application provides a linear module having a first direction and a second direction, the first direction intersecting the second direction. The linear module includes: a guide rail extending along the first direction; and a sliding component slidably connected to the guide rail. The sliding component includes a main body, at least one fixing member, and a plurality of sliding members. The sliding members are connected to both ends of the main body along the second direction, and each sliding member is slidably connected to the guide rail and slides relative to the guide rail along the first direction. At least one end of the main body along the second direction is provided with a sliding groove, and at least a portion of the sliding members pass through the sliding groove and slide relative to the sliding groove along the second direction. When the sliding member slides relative to the sliding groove along the second direction to a preset position, the main body and the sliding member are fixedly connected by at least one fixing member.
[0007] The linear module of this application has the following advantages:
[0008] In the linear module of this application, the sliding component of the sliding assembly is slidably connected to the guide rail to form a linear module that moves along a first direction. During the operation of the linear module, wear may occur between the sliding component and the guide rail due to factors such as load changes, temperature fluctuations, or long-term use. Therefore, it is necessary to adjust the preload between the sliding component and the guide rail located on both sides of the guide rail along a second direction at any time. In the sliding assembly, since at least one end of the main body is provided with a sliding groove along the second direction, and at least a portion of the sliding component passes through the sliding groove and slides relative to the sliding groove along the second direction, when it is necessary to adjust the preload between the sliding component and the guide rail, the sliding component passing through the sliding groove can be adjusted. The moving part slides relative to the sliding groove along the second direction, which changes the distance between the sliding parts located on both sides of the guide rail along the second direction. When the distance between the sliding parts on both sides of the guide rail along the second direction changes, the force exerted on the guide rail by the sliding parts on both sides of the guide rail along the second direction can be changed, thereby changing the preload between the sliding parts and the guide rail. Therefore, the linear module of this application can adjust the preload at any time. During the adjustment of the preload, when the sliding part slides relative to the sliding groove along the second direction to a preset position, the main body and the sliding part can be fixed by at least one fixing member to improve the structural stability of the sliding part when it slides relative to the guide rail along the first direction.
[0009] In an optional embodiment, the main body is provided with a plurality of sliding grooves at one end along the second direction, and the plurality of sliding members include a plurality of first sliding members. Each first sliding member is slidably connected to the guide rail and slides relative to the guide rail along the first direction. Each first sliding member passes through a sliding groove and slides relative to the sliding groove along the second direction. When the first sliding member slides relative to the sliding groove along the second direction to a preset position, the main body and the first sliding member are fixedly connected by at least one fixing member.
[0010] In an optional embodiment, the plurality of sliding members further includes a plurality of second sliding members, each of the second sliding members being fixedly connected to one end of the main body member away from the sliding groove along the second direction, and each of the second sliding members being correspondingly arranged with one of the first sliding members in the second direction, each of the second sliding members being slidably connected to the guide rail, and the second sliding member sliding relative to the guide rail along the first direction.
[0011] In an optional embodiment, the main body is provided with a plurality of sliding grooves at both ends along the second direction, and each sliding member passes through one of the sliding grooves and slides relative to the sliding groove along the second direction.
[0012] In an optional embodiment, the sliding groove has a first groove wall and a second groove wall, the first groove wall and the second groove wall are spaced apart along the first direction, and the first groove wall protrudes into the sliding groove along the first direction, and the second groove wall protrudes into the sliding groove along the first direction.
[0013] Secondly, this application provides a pre-pressure adjustment device for adjusting the pre-pressure of a linear module as described in any of the foregoing embodiments. The pre-pressure adjustment device includes: a first clamping member for abutting against a sliding member at one end of the linear module along a second direction and against one side of the sliding member along the second direction; a second clamping member for abutting against a sliding member at the other end of the linear module along the second direction and against one side of the sliding member along the second direction; wherein the first clamping member and / or the second clamping member move relative to the guide rail along the second direction.
[0014] The pre-pressure regulating device of this application has the following advantages:
[0015] In the proposed pre-pressure adjustment device, since the first clamping member abuts against the sliding member at one end of the linear module along the second direction and against one side of the sliding member along the second direction, and the second clamping member abuts against the sliding member at the other end of the linear module along the second direction and against one side of the sliding member along the second direction, the sliding component can be clamped by the pre-pressure adjustment device. Furthermore, since the first clamping member and / or the second clamping member move relative to the guide rail along the second direction, the sliding member in the sliding groove can be pushed to move along the second direction by the first clamping member and / or the second clamping member, so that the distance between the sliding members located on both sides of the guide rail along the second direction changes, thereby changing the pre-pressure between the sliding member and the guide rail. Therefore, the pre-pressure adjustment device of this application can improve the convenience of pre-pressure adjustment of the linear module.
[0016] In an optional embodiment, the pre-pressure adjusting device further includes a connector that extends along the second direction, and both the first clamping member and the second clamping member are connected to the connector, with the second clamping member being movably connected to the connector and moving relative to the connector along the second direction.

[0040] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, the linear module 10 involved in this application embodiment has a first direction x and a second direction y, the first direction x and the second direction y intersect, and the linear module 10 includes: a guide rail 100 and a sliding component 200.
[0041] Specifically, the guide rail 100 extends along the first direction x; the sliding component 200 is slidably connected to the guide rail 100. The sliding component 200 includes a main body 210, at least one fixing member (not shown), and a plurality of sliding members 220. The main body 210 is connected to sliding members 220 at both ends along the second direction y, and each sliding member 220 is slidably connected to the guide rail 100 and slides relative to the guide rail 100 along the first direction x. The main body 210 is provided with a sliding groove 211 at at least one end along the second direction y. At least some of the sliding members 220 pass through the sliding groove 211 and slide relative to the sliding groove 211 along the second direction y. When the sliding member 220 slides relative to the sliding groove 211 along the second direction y to a preset position, the main body 210 and the sliding member 220 are fixedly connected by at least one fixing member.
[0042] It should be noted that the first direction x is Figure 1 The direction indicated by x in the middle, and the second direction y is... Figure 1 The direction indicated by y in the middle.
[0043] In the linear module 10 of this application, the sliding member 220 of the sliding assembly 200 is slidably connected to the guide rail 100 to form a linear module 10 that moves along the first direction x. During the operation of the linear module 10, wear may occur between the sliding member 220 and the guide rail 100 due to factors such as load changes, temperature fluctuations, or long-term use. Therefore, it is necessary to adjust the preload between the sliding member 220 and the guide rail 100 located on both sides of the guide rail 100 along the second direction y at any time. In the sliding assembly 200, since the main body 210 is provided with a sliding groove 211 at at least one end along the second direction y, and at least a portion of the sliding member 220 passes through the sliding groove 211 and slides relative to the sliding groove 211 along the second direction y, when it is necessary to adjust the preload between the sliding member 220 and the guide rail 100, the sliding member 220 passing through the sliding groove 211 can be adjusted. The slider 220 slides relative to the sliding groove 211 along the second direction y. This allows the distance between the sliders 220 located on both sides of the guide rail 100 along the second direction y to change. When the distance between the sliders 220 on both sides of the guide rail 100 along the second direction y changes, the force exerted on the guide rail 100 by the sliders 220 on both sides of the guide rail 100 along the second direction y can be changed, thereby changing the preload between the slider 220 and the guide rail 100. Therefore, the linear module 10 of this application can adjust the preload at any time. During the adjustment of the preload, when the slider 220 slides relative to the sliding groove 211 along the second direction y to a preset position, the main body 210 and the slider 220 can be fixed by at least one fixing member to improve the structural stability of the slider 220 when it slides relative to the guide rail 100 along the first direction x.
[0044] Specifically, in this embodiment, the preset position can be the position of the slider 220 in the sliding groove 211 in the second direction y under any required preload.
[0045] Reference Figure 4As shown, in some embodiments, the main body 210 has a plurality of sliding grooves 211 at one end along the second direction y. The plurality of sliding members 220 include a plurality of first sliding members 221. Each first sliding member 221 is slidably connected to the guide rail 100 and slides relative to the guide rail 100 along the first direction x. Each first sliding member 221 passes through a sliding groove 211 and slides relative to the sliding groove 211 along the second direction y. When the first sliding member 221 slides relative to the sliding groove 211 along the second direction y to a preset position... At that time, the main body 210 and the first sliding member 221 are fixedly connected by at least one fastener; the multiple sliding members 220 also include multiple second sliding members 222, each second sliding member 222 is fixedly connected to one end of the main body 210 away from the sliding groove 211 along the second direction y, and each second sliding member 222 is correspondingly arranged with a first sliding member 221 in the second direction y, each second sliding member 222 is slidably connected to the guide rail 100, and the second sliding member 222 slides relative to the guide rail 100 along the first direction x.
[0046] In this embodiment, since the main body 210 has multiple sliding grooves 211 at one end along the second direction y, and each first sliding member 221 passes through a sliding groove 211 and slides relative to the sliding groove 211 along the second direction y, the position of the first sliding member 221 in the sliding groove 211 along the second direction y can be adjusted, thereby adjusting the relative position between the first sliding member 221 and the guide rail 100 in the second direction y, thereby adjusting the preload between the sliding assembly 200 and the guide rail 100. Simultaneously, during the adjustment of the preload, when the first sliding member 221 slides relative to the sliding groove 211 along the second direction y to a preset position, the main body 210 can be fixed by the fixing member. The body 210 is fixed to the first sliding member 221 to improve the structural stability of the first sliding member 221 when it slides relative to the guide rail 100 along the first direction x. Since each second sliding member 222 is fixedly connected to the end of the body 210 away from the sliding groove 211 along the second direction y, when the position of the first sliding member 221 in the sliding groove 211 in the second direction y changes, the distance between the first sliding member 221 and the second sliding member 222 in the second direction y can change. In this way, the force on the guide rail 100 by the first sliding member 221 and the second sliding member 222 can be adjusted, thereby changing the preload between the sliding assembly 200 and the guide rail 100.
[0047] Specifically, in some other embodiments, the main body 210 is provided with a plurality of sliding grooves 211 at both ends along the second direction y, and each sliding member 220 passes through a sliding groove 211 and slides relative to the sliding groove 211 along the second direction y.
[0048] In this embodiment, the sliding members 220 at both ends of the main body 210 along the second direction y can be moved relative to the main body 210 along the second direction y, thereby adjusting the distance between the sliding members 220 at both ends of the main body 210 along the second direction y, thereby adjusting the force on the guide rail 100 by the sliding members 220 on both sides of the guide rail 100 along the second direction y, and changing the preload between the sliding members 220 and the guide rail 100.
[0049] Continue to refer to Figure 4 As shown, the sliding groove 211 has a first groove wall 2111 and a second groove wall 2112. The first groove wall 2111 and the second groove wall 2112 are spaced apart along the first direction x, and the first groove wall 2111 protrudes into the sliding groove 211 along the first direction x, and the second groove wall 2112 protrudes into the sliding groove 211 along the first direction x.
[0050] In this embodiment, since the first groove wall 2111 and the second groove wall 2112 are spaced apart along the first direction x, the first groove wall 2111 and the second groove wall 2112 can respectively abut against the two side walls of the slider 220 along the first direction x, thereby limiting the slider 220 and preventing the slider 220 from moving relative to the sliding groove 211 along the first direction x. Since the first groove wall 2111 protrudes into the sliding groove 211 along the first direction x, and the second groove wall 2112 protrudes into the sliding groove 211 along the first direction x, the first side wall and the second side wall can form a clamping state on the slider 220, thereby improving the stability of the abutment relationship between the first groove wall 2111 and the second groove wall 2112 and the side walls of the slider 220, further preventing the slider 220 from moving relative to the sliding groove 211 along the first direction x, and improving the structural stability of the slider 220 in the sliding groove 211.
[0051] Reference Figure 3 as well as Figure 5As shown, in this embodiment, the slider 220 includes a sliding portion 223, a return portion 224, and a rolling portion 225. The sliding portion 223 is provided with a first rolling groove 2231, which extends along a first direction x. The guide rail 100 is provided with a second rolling groove 110, which extends along the first direction x and communicates with the first rolling groove 2231. When the slider 220 slides relative to the guide rail 100 along the first direction x, the rolling portion 225 rolls simultaneously within the first rolling groove 2231 and the second rolling groove 110 to improve the smoothness of the slider 220 sliding relative to the guide rail 100. The return portion 224 is embedded in the sliding portion 223. The first rolling groove 2231 is surrounded by a return channel 2241. The inlet and outlet of the return channel 2241 are respectively connected to the two ends of the first rolling groove 2231 along the first direction x. When the rolling part 225 rolls along the first direction x to one end of the first rolling groove 2231 along the first direction x, the rolling part 225 will enter the return channel 2241 and return to the other end of the first rolling groove 2231 along the first direction x through the return channel 2241, so as to realize the reciprocating motion of the rolling part 225 between the two ends of the first rolling groove 2231 along the first direction x, and reduce the wear of the rolling part 225 when rolling along the first direction x.
[0052] Specifically, in this embodiment, the main body 210 and the return section 224 are fixedly connected by a fastener to fix the main body 210 and the sliding member 220.
[0053] Reference Figure 1 , Figure 6 as well as Figure 7 As shown, the pre-pressure adjustment device 20 involved in the embodiments of this application is used to adjust the pre-pressure of the linear module 10. The pre-pressure adjustment device 20 includes a first clamping member 21 and a second clamping member 22.
[0054] Specifically, the first clamping member 21 is used to abut against the slider 220 at one end of the linear module 10 along the second direction y, and abut against one side of the slider 220 along the second direction y; the second clamping member 22 is used to abut against the slider 220 at the other end of the linear module 10 along the second direction y, and abut against one side of the slider 220 along the second direction y; wherein, the first clamping member 21 and / or the second clamping member 22 move relative to the guide rail 100 along the second direction y.
[0055] In the applied pre-pressure adjustment device 20, since the first clamping member 21 abuts against the sliding member 220 at one end of the linear module 10 along the second direction y, and abuts against one side of the sliding member 220 along the second direction y, and the second clamping member 22 abuts against the sliding member 220 at the other end of the linear module 10 along the second direction y, and abuts against one side of the sliding member 220 along the second direction y, the sliding assembly 200 can be clamped by the pre-pressure adjustment device 20. Furthermore, since the first clamping member 21... The first clamping member 21 and / or the second clamping member 22 can move relative to the guide rail 100 along the second direction y. Therefore, the first clamping member 21 and / or the second clamping member 22 can push the sliding member 220 in the sliding groove 211 to move along the second direction y, so that the distance between the sliding members 220 located on both sides of the guide rail 100 along the second direction y changes, thereby changing the pre-pressure between the sliding member 220 and the guide rail 100. Therefore, the pre-pressure adjustment device 20 of this application can improve the convenience of pre-pressure adjustment of the linear module 10.
[0056] Reference Figure 7 As shown, in some embodiments, the pre-pressure regulating device 20 further includes a connector 23, which extends along the second direction y. The first clamping member 21 and the second clamping member 22 are both connected to the connector 23, and the second clamping member 22 is movably connected to the connector 23. The second clamping member 22 moves relative to the connector 23 along the second direction y.
[0057] In this embodiment, the first clamping member 21 and the second clamping member 22 can be connected by the connecting member 23, and the first clamping member 21 and the second clamping member 22 are spaced apart along the second direction y, so as to realize the clamping of the sliding component 200 by the pre-pressure adjustment device 20. Since the second clamping member 22 moves relative to the connecting member 23 along the second direction y, when the second clamping member 22 moves relative to the connecting member 23 towards the first clamping member 21 along the second direction y, the distance between the first clamping member 21 and the second clamping member 22 along the second direction y will be shortened, thereby pushing the sliding member 220 in the sliding groove 211 to move along the second direction y, further changing the distance between the sliding members 220 located on both sides of the guide rail 100 along the second direction y, thereby changing the pre-pressure between the sliding member 220 and the guide rail 100.
[0058] Specifically, refer to Figure 6As shown, in this embodiment, the pre-pressure adjustment device 20 further includes a pressure sensor (not shown). The first clamping member 21 includes a first connecting portion 231 and a first clamping portion 251 connected to the first connecting portion 231. The second clamping member 22 includes a second connecting portion 202 and a second clamping portion 212 connected to the second connecting portion 202. The first connecting portion 231 is movably connected to the connecting member 23. The second connecting portion 202 moves relative to the connecting member 23 along the second direction y. The first clamping portion 251 abuts against the first sliding member 221, and a pressure sensor is provided on the side of the first clamping portion 251 near the first sliding member 221. The second clamping part 212 abuts against the second sliding member 222, and a pressure sensor is provided on the side of the second clamping part 212 near the second sliding member 222. In this way, the pressure between the first clamping part 251 and the first sliding member 221 can be monitored by the pressure sensor, and the pressure between the second clamping part 212 and the second sliding member 222 can also be monitored. When the pressure value of the pressure sensor is a preset pressure value, the sliding member 220 moves to a preset position in the sliding groove 211 along the second direction y, thereby improving the positional accuracy of the sliding member 220 in the sliding groove 211 along the second direction y.
[0059] Continue to refer to Figure 7 As shown, the connector 23 is rotatably connected to the first clamping member 21, and the connector 23 rotates relative to the first clamping member 21 about the second direction y. The second clamping member 22 is threadedly connected to the connector 23.
[0060] In this embodiment, since the connector 23 rotates relative to the first clamping member 21 about the second direction y, and the second clamping member 22 is threadedly connected to the connector 23, when the connector 23 rotates about the second direction y, it can drive the second clamping member 22 to move relative to the connector 23 along the second direction y, so that the distance between the first clamping member 21 and the second clamping member 22 along the second direction y changes.
[0061] Continue to refer to Figure 7 As shown, the pre-pressure adjustment device 20 also includes a drive assembly 24, which includes a drive member 241, a first transmission member 242, and a second transmission member 243. The first transmission member 242 is connected to the drive member 241 and meshes with the second transmission member 243 for transmission. The drive member 241 is used to drive the first transmission member 242 to rotate, and the first transmission member 242 is used to drive the second transmission member 243 to rotate around the second direction y. The second transmission member 243 is connected to the connecting member 23 and is coaxially arranged with the connecting member 23.
[0062] In this embodiment, the first transmission member 242 is driven to rotate by the driving member 241, so that the first transmission member 242 drives the second transmission member 243 to rotate around the second direction y, and further causes the second transmission member 243 to drive the connecting member 23 to rotate around the second direction y, thereby causing the second clamping member 22 to move relative to the connecting member 23 along the second direction y.
[0063] Specifically, in this embodiment, the first transmission component 242 is a worm gear, and the second transmission component 243 is a worm wheel. The worm gear and the worm wheel mesh and transmit power. The worm gear extends along the first direction x and rotates around the first direction x, so as to drive the worm wheel to rotate around the second direction y through the worm gear.
[0064] Continue to refer to Figure 7 As shown, the first clamping member 21 is provided with a guide space 201, which extends along the second direction y. The connecting member 23 is disposed in the guide space 201, and the two ends of the connecting member 23 along the second direction y are respectively rotatably connected to the first clamping member 21. The second clamping member 22 is at least partially inserted into the guide space 201 and abuts against the two side walls of the guide space 201 along the first direction x. The second clamping member 22 moves relative to the guide space 201 along the second direction y.
[0065] In this embodiment, since the guide space 201 extends along the second direction y, and the second clamping member 22 is at least partially inserted into the guide space 201 and abuts against the two side walls of the guide space 201 along the first direction x, when the second clamping member 22 moves along the second direction y, the guide space 201 can guide and limit the movement of the second clamping member 22, ensuring that the second clamping member 22 can move along the second direction y and restricting the movement of the second clamping member 22 in the first direction x, thereby improving the directional accuracy of the movement of the second clamping member 22.
[0066] Specifically, in some other embodiments, the first clamping member 21 moves relative to the connecting member 23 along the second direction y, and the second clamping member 22 is fixedly connected to the connecting member 23, so as to change the distance between the first clamping member 21 and the second clamping member 22 along the second direction y by moving the first clamping member 21 along the second direction y.
[0067] Specifically, in some other embodiments, both the first clamping member 21 and the second clamping member 22 move relative to the connecting member 23 along the second direction y, so as to change the distance between the first clamping member 21 and the second clamping member 22 along the second direction y by moving the first clamping member 21 and the second clamping member 22 along the second direction y.
