Description

Technical Field

[0001] This utility model relates to the field of linear guide rail technology, and in particular to a linear guide rail that is easy to install. Background Technology

[0002] Linear guides, based on the principles of rolling or sliding friction, provide high-precision, low-resistance linear motion guidance for moving parts of equipment. Rolling linear guides convert sliding friction into rolling friction by having steel balls or rollers roll between the guide rail and the slider, significantly reducing friction. Sliding linear guides rely on direct contact between the guide rail and the slider using wear-resistant materials (such as engineering plastics or bronze alloys), and reduce friction through a lubrication system. Both types eliminate backlash through preload design, ensuring smooth movement and repeatable positioning accuracy.

[0003] A linear guide rail, Chinese patent number CN222650376U, includes: a track, a slider, and two reverse covers. The slider is slidably connected to the track, and the two reverse covers are respectively connected to both ends of the slider. A straight ball track is formed inside the slider, and another straight ball track is formed between the slider and the track. A reverse ball track is formed inside the reverse covers. The two straight ball tracks and the two reverse ball tracks form a circulating ball track. By improving the reverse ball track, the width of the steel ball entry section is set to be larger. The steel ball starts to turn from entering the first ball track section. The larger width can reduce the initial impact force of the steel ball on the lip of the reverse cover. When entering the second ball track section of the reverse cover, the width is appropriately reduced to ensure that the steel ball does not move around inside the reverse cover, thereby improving the stability of the slider during operation.

[0004] Most guide rails use detachable limit blocks, which have problems such as frequent disassembly leading to loss and cumbersome installation steps. In actual industrial production scenarios, detachable limit blocks are usually connected to the guide rail by bolts or clips to limit the range of motion of the slider. This structure requires frequent disassembly and installation of the limit blocks when maintaining, debugging or replacing sliders of different specifications, which further increases the difficulty of installation and time cost. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a linear guide rail that is easy to install, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes an equipment mounting base, with a linear guide rail body fixedly connected to its upper end. A sliding top block is slidably connected to the upper end of the linear guide rail body. Auxiliary slots are symmetrically formed on the front and rear sides of the upper end of the linear guide rail body. Supports are fixedly connected to the front and rear sides of the inner ends of the auxiliary slots. A 90-degree self-rebound damping rotating shaft is installed within the support. Self-adaptive limiting plates are rotatably connected to the outer ends of the 90-degree self-rebound damping rotating shaft. The two self-adaptive limiting plates are located at the front and rear of the sliding top block. On both sides, a second electromagnetic strip is fixedly connected to the inner wall of the two auxiliary slots that are close to each other, and a first electromagnetic strip is fixedly connected to the inner wall of the two second electromagnetic strips that are far apart from each other. The first and second electromagnetic strips are magnetically connected to the self-adaptive limiting plate. Electrically controlled inner chambers are symmetrically opened at the front and rear ends of the sliding top block. A sealed chamber door is hinged to the outer end of the electrically controlled inner chamber. The sealed chamber door and the electrically controlled inner chamber are interlocked. A second control button is fixedly connected to the left end of the inner wall of the electrically controlled inner chamber, and a first control button is fixedly connected to the right end of the inner wall of the electrically controlled inner chamber.

[0007] As a further technical solution of this utility model, the two first control buttons are electrically connected to the corresponding first electromagnetic strips, and the two second control buttons are electrically connected to the corresponding second electromagnetic strips.

[0008] As a further technical solution of this utility model, a strip-shaped transverse range scale is fixedly connected to the upper right side of the sliding top block, and a reinforcing inner plate is fixedly connected to the end of each of the two self-adaptive limiting plates that are close to each other.

[0009] As a further technical solution of this utility model, a circular groove is provided in the middle of one end of the two self-adaptive limiting plates that are close to each other, and a buffer spring is fixedly connected to the inner side wall of the circular groove.

[0010] As a further technical solution of this utility model, a contact sensor is fixedly connected to the end of the buffer spring away from the self-adaptive limiting plate, and the two contact sensors cooperate with the front and rear sides of the sliding top block.

[0011] As a further technical solution of this utility model, multiple locking columns are symmetrically fixedly connected to the upper left and right sides of the equipment mounting base, and the multiple locking columns are distributed at equal intervals.

[0012] This invention provides a linear guide rail that is easy to install, and has the following advantages compared with the prior art:

[0013] 1. The locking column of the equipment mounting base in this design enables quick connection with external equipment. In conjunction with the linkage of the self-adaptive limit plate and the electromagnetic strip, the sliding top block automatically completes positioning when it is inserted into the guide rail, without the need for manual adjustment or additional limit blocks. This avoids the problem of easy loss of traditional detachable limit blocks. At the same time, the automatic reset function of the damping shaft reduces maintenance steps. The electric control compartments at both ends of the sliding top block have built-in control circuits and are protected by sealed compartment doors. The first control button acts as a control switch, which can trigger the on / off state of the first and second electromagnetic strips, thereby controlling the rotation angle of the self-adaptive limit plate.

[0014] 2. The contact sensing system in this design achieves real-time monitoring and early warning of the displacement error of the sliding top block through the elastic cooperation of the buffer spring and the contact sensor. If the sliding top block exceeds the range of the scale bar due to the deformation of the guide rail or uneven load, the compression of the buffer spring changes, the pressure value of the contact sensor exceeds the threshold, and the staff is reminded to come for maintenance, which effectively improves the reliability of the linear guide rail body in long-term operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a linear guide rail technology solution that is easy to install: it includes an equipment mounting base 1, a linear guide rail body 2 fixedly connected to the upper end of the equipment mounting base 1, a sliding top block 3 slidably connected to the upper end of the linear guide rail body 2, auxiliary slots 4 symmetrically opened on the front and rear sides of the upper end of the linear guide rail body 2, a bracket 5 fixedly connected to the front and rear sides of the inner end of the auxiliary slot 4, a 90-degree self-rebound damping rotating shaft 17 installed in the bracket 5, a self-adaptive limiting plate 6 rotatably connected to the outer end of the 90-degree self-rebound damping rotating shaft 17, two self-adaptive limiting plates 6 located on the front and rear sides of the sliding top block 3, a second electromagnetic strip 8 fixedly connected to the inner wall of the two auxiliary slots 4 that are close to each other, a first electromagnetic strip 7 fixedly connected to the inner wall of the two second electromagnetic strips 8 that are far apart from each other, and the first electromagnetic strip 7 and the second electromagnetic strip 8 magnetically connected to the self-adaptive limiting plate 6.

[0022] Working principle: The equipment mounting base 1 serves as the basic support structure. Multiple locking columns 19 symmetrically distributed on the left and right sides enable quick connection with external equipment. The equidistant arrangement of the locking columns 19 ensures uniform force distribution. The linear guide rail body 2 is fixed to the upper end of the equipment mounting base 1, forming a stable linear motion platform. The sliding top block 3 is located on the upper end of the linear guide rail body 2 and can slide freely along the guide rail direction. When the sliding top block 3 is horizontally inserted into the guide rail, its front inclined surface presses against the self-adaptive limiting plate 6, causing it to rotate around the rotating shaft 17 to a vertical state. At this time, the first electromagnetic strip 7 is energized to attract the limiting plate 6 and maintain the limiting state. When the sliding top block 3 exits the guide rail, the electromagnetic force disappears, and the damping rotating shaft 17 automatically pulls the limiting plate 6 back to a horizontal state under the action of the spring and is tightly stored by the second electromagnetic strip 8, allowing the sliding top block 3 to be smoothly pushed out without manual adjustment or installation of additional limiting blocks. The positioning is automatically completed when the slider is inserted.

[0023] like Figures 2-3 As shown, the sliding top block 3 has symmetrically opened electrically controlled inner chambers 9 at its front and rear ends. The outer end of the electrically controlled inner chamber 9 is hinged to a sealed chamber door 10. The sealed chamber door 10 and the electrically controlled inner chamber 9 are interlocked. The left end of the inner wall of the electrically controlled inner chamber 9 is fixedly connected to a second control button 12, and the right end of the inner wall of the electrically controlled inner chamber 9 is fixedly connected to a first control button 11. The two first control buttons 11 are electrically connected to the corresponding first electromagnetic strips 7, and the two second control buttons 12 are electrically connected to the corresponding second electromagnetic strips 8.

[0024] Working principle: The electronically controlled inner compartments 9 at both ends of the sliding top block 3 have built-in control circuits and are protected by the sealed compartment door 10. The first control button 11 acts as a control switch, which can trigger the on / off state of the first electromagnetic strip 7 and the second electromagnetic strip 8, thereby controlling the rotation angle of the self-adaptive limit plate 6.

[0025] like Figure 2 , Figure 4 As shown, a strip-shaped horizontal movement range scale 18 is fixedly connected to the upper right side of the sliding top block 3. A reinforcing inner side plate 13 is fixedly connected to the two self-adaptive limiting plates 6 at their close ends. A circular slot 14 is opened in the middle of the two self-adaptive limiting plates 6 at their close ends. A buffer spring 15 is fixedly connected to the inner wall of the circular slot 14. A contact sensor 16 is fixedly connected to the end of the buffer spring 15 away from the self-adaptive limiting plate 6. The two contact sensors 16 cooperate with the front and rear sides of the sliding top block 3. Multiple locking columns 19 are symmetrically fixedly connected to the upper left and right sides of the equipment mounting base 1. The multiple locking columns 19 are equidistantly distributed.

[0026] Working principle: The contact sensing system uses the elastic cooperation between the buffer spring 15 and the contact sensor 16 to realize real-time monitoring and early warning of the displacement error of the sliding top block 3. If the sliding top block 3 exceeds the range of the scale bar 18 due to the deformation of the guide rail or uneven load, the compression of the buffer spring 15 changes, and the pressure value of the contact sensor 16 exceeds the threshold, reminding the staff to come for maintenance, which effectively improves the reliability of the linear guide rail body 3 in long-term operation.

[0027] The working principle of this utility model is as follows: The equipment mounting base 1 serves as the basic support structure. Multiple locking columns 19 symmetrically distributed on the left and right sides enable quick connection with external equipment. The equidistant arrangement of the locking columns 19 ensures uniform force distribution. The linear guide rail body 2 is fixed to the upper end of the equipment mounting base 1, forming a stable linear motion platform. The sliding top block 3 is located at the upper end of the linear guide rail body 2 and can slide freely along the guide rail direction. When the sliding top block 3 is horizontally inserted into the guide rail, its front inclined surface presses against the self-adaptive limiting plate 6, causing it to rotate around the rotating shaft 17 to a vertical state. At this time, the first electromagnetic strip 7 is energized to attract the limiting plate 6 and maintain the limiting state. When the sliding top block 3 exits the guide rail, the electromagnetic force disappears, and the damping rotating shaft 17 automatically pulls the limiting plate 6 back to a horizontal state under the action of the spring and is tightly stored by the second electromagnetic strip 8, allowing the sliding top block 3 to be smoothly pushed out without manual adjustment or installation of additional limiting blocks. The sliding block insertion is completed automatically. Positioning: Traditional detachable limit blocks are easily lost during frequent disassembly, which is time-consuming and laborious. This significantly improves the efficiency of equipment assembly and maintenance. The strip-shaped horizontal movement range scale 18 on the upper end of the sliding top block 3 displays the sliding position in real time. The electric control inner compartment 9 at both ends of the sliding top block 3 has built-in control circuits and is protected by a sealed compartment door 10. The first control button 11 acts as a control switch, which can trigger the on / off state of the first electromagnetic strip 7 and the second electromagnetic strip 8, thereby controlling the rotation angle of the self-adaptive limit plate 6. The contact sensing system realizes real-time monitoring and early warning of the displacement error of the sliding top block 3 through the elastic cooperation of the buffer spring 15 and the contact sensor 16. If the sliding top block 3 exceeds the range of the scale 18 due to guide rail deformation, uneven load, etc., the compression of the buffer spring 15 changes, and the pressure value of the contact sensor 16 exceeds the threshold, reminding the staff to come for maintenance, effectively improving the reliability of the linear guide rail body 3 in long-term operation.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
