Description

Technical Field

[0001] This utility model relates to the field of linear roller guide technology, and in particular to a linear roller guide fixing mechanism. Background Technology

[0002] Linear roller guides are mechanical transmission components that achieve linear motion by rolling rollers between a slider and a guide rail. They are characterized by high load-bearing capacity and high rigidity and are commonly used in heavy machine tools and large-scale automated equipment.

[0003] In existing technologies, linear roller guides are generally fixed with bolts; however, this fixing method has certain drawbacks: bolt installation is inconvenient, requiring multiple rotations to tighten the bolts, and disassembly requires special tools, making the operation cumbersome and complex, increasing time costs and labor costs; on the other hand, bolts are prone to rust when exposed to air for a long time, requiring regular replacement, which increases maintenance costs and operational complexity.

[0004] Therefore, there is an urgent need to provide a linear roller guide fixing mechanism to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a linear roller guide fixing mechanism.

[0006] To solve the above technical problems, the present invention provides a linear roller guide rail fixing mechanism, including a base, a guide rail body placed on the base, two blocks fixedly connected to the front and rear ends of the guide rail body, two side plates fixedly connected to the sides of the two blocks, both located on the top of the base, protective covers fixedly connected to the front and rear ends of the base, a positioning mechanism slidably connected inside the protective cover, an opposing mechanism rotatably connected inside the protective cover, and a limit mechanism slidably connected inside the protective cover.

[0007] The protective cover is rotatably connected to a one-way mechanism.

[0008] The present invention is further configured such that: the positioning mechanism includes multiple sleeves respectively fixedly connected inside two protective covers, each sleeve having a fixed block slidably connected inside it, each fixed block having an inclined surface at one end facing the second block, and the bottom of each fixed block contacting the top of the side plate, each fixed block having two shafts slidably connected to the sleeve at one end away from the second block, each shaft having a spring sleeved on its outside, and each fixed block having an L-shaped rod passing through the sleeve at one end away from the second block.

[0009] Through the above technical solution, the core function of the positioning mechanism is to achieve precise positioning and stable fixation of the guide rail body. When fixing the linear roller guide rail, the operator must first align the two blocks at both ends of the guide rail body with the protective cover, and at the same time ensure that the side plates on both sides of the two blocks are aligned with the inclined guide surfaces of the two sets of fixing blocks. Then, a vertical downward pressure is applied to the two blocks, at which point the side plates move down and come into contact with the inclined surfaces of the fixing blocks. As the downward pressure continues, the side plates transmit the horizontal thrust to the fixing blocks through the inclined surface contact, forcing the fixing blocks to move axially along the spring compression direction. During this process, the spring is continuously compressed and stores energy until the side plates completely pass over the inclined surface area of ​​the fixing blocks and reach their bottom predetermined position. When the side plates complete their downward stroke, the compressed spring is immediately released. The elastic force pushes the fixing block to quickly reset; at this time, the bottom plane of the reset fixing block forms a stable contact with the top plane of the side plate. Through the coordinated action of multiple sets of fixing blocks, the side plate is locked in both directions, and the fixing of the side plate effectively constrains the second block, ultimately achieving a stable fixation of the guide rail body. Through the combination of mechanical linkage and elastic elements, a fast and reliable one-button locking function is achieved. During the unlocking operation, simply pull the L-shaped rod along the axis to drive the fixing block to overcome the spring resistance and disengage from the contact surface with the side plate, which instantly releases the constraint on the side plate, thereby releasing the second block and ultimately achieving a fast unlocking of the guide rail body. This design, through the ingenious combination of inclined plane transmission mechanism and elastic reset device, ensures both the simplicity of the operation process and the mechanical stability in the fixed state.

[0010] The present invention is further configured such that: the opposing mechanism includes two rotating shafts respectively rotatably connected inside two protective covers, and gear disks are respectively fixedly connected to the outside of the two rotating shafts. The upper and lower ends of the two gear disks are meshed with racks. Two plates located on both sides of block two are slidably connected inside the two protective covers. Multiple plates two are respectively fixedly connected to multiple racks.

[0011] Through the above technical solution, the core function of the opposing mechanism is to achieve automatic centering adjustment of the guide rail body, ensuring that it is always in a precise center position. The operator rotates the handle, causing the connected rotating shaft to rotate. The rotation of the rotating shaft further drives the gear disc to rotate synchronously, and the rotation of the gear disc is converted into linear movement of the upper and lower racks. It is particularly noteworthy that the two racks always move in opposite directions, i.e., simultaneously towards the central gear disc. As the racks move in opposite directions, the two plate assemblies connected to the racks also undergo synchronous displacement, moving smoothly towards the gear disc. During the movement of the plate assemblies, the two plate assemblies gradually move closer to the side plates on both sides. When the rotating shaft reaches its maximum rotation angle and can no longer continue... During continuous rotation, the two plate components simultaneously achieve complete contact with the side plates on both sides. This synchronous contact mechanism ensures that the two side plates always maintain a perfect mirror symmetry relationship. Furthermore, through the symmetrical positioning effect of the side plates, the guide rail body is precisely adjusted and fixed in the center position. The design advantage of this mechanism is that it realizes the automatic centering function of the guide rail body, eliminating the need for repeated manual adjustments. Precise centering adjustment can be achieved through simple rotation. This mechanical automatic adjustment method not only significantly improves work efficiency and reduces the labor intensity of operators, but also ensures the stability and accuracy of the adjustment process, providing a reliable guarantee for the precise positioning of the guide rail. The entire adjustment process is simple, quick, and intuitive, fully demonstrating the practicality and efficiency of the mechanical design.

[0012] The present invention is further configured such that: the limiting mechanism includes multiple cylinders 2 respectively fixedly connected in two protective covers, each of the multiple cylinders 2 having a shaft 3 slidably connected to one end of the cylinders 2 facing the block 2, each of the multiple shaft 3 having one end of the shaft 3 facing the block 2 being fixedly connected to multiple plates 2, and each of the multiple cylinders 2 having a tension spring sleeved on its exterior.

[0013] Through the above technical solution, the main function of the limiting mechanism is to precisely limit and guide the movement of plate two. When plate two is displaced, it will drive shaft three connected to it to slide linearly in the inner cavity of cylinder two. Through the precisely matched guide structure between shaft three and cylinder two, it is ensured that plate two strictly follows the preset linear trajectory during movement, completely avoiding any form of deflection or offset, thereby achieving high-precision motion guidance and reliable limiting and guiding functions. At the same time, during the displacement of plate two assembly, the tension spring connected to it will be pulled synchronously, causing the tension spring to generate elastic deformation and store potential energy. This design not only ensures the smoothness of the movement of plate two assembly, but also provides the necessary restoring force for the system through the elastic action of the tension spring, further enhancing the motion stability and control accuracy of the entire mechanism. This limiting mechanism achieves precise constraint and reliable control of the movement trajectory of plate two assembly through the organic combination of mechanical guidance and elastic elements.

[0014] The present invention is further configured such that: the one-way mechanism includes two one-way ratchet wheels respectively fixedly connected to the outside of the two rotating shafts; pawls that mesh with the one-way ratchet wheels are respectively rotatably connected inside the two protective covers; and handles are installed at the ends of the two rotating shafts away from the guide rail body.

[0015] Through the above technical solution, the core function of the one-way mechanism is to achieve precise positioning and one-way locking of the gear disc. When the operator drives the rotating shaft to rotate, the rotating shaft drives the gear disc to rotate synchronously. The rotation of the gear disc further drives the two plate assemblies to move towards the side plates on both sides. During this process, the rotational motion of the rotating shaft is simultaneously transmitted to the connected one-way ratchet, causing the one-way ratchet to rotate accordingly. Under the mechanical limiting action of the pawl, the one-way ratchet can only rotate in the set direction and cannot rotate in the opposite direction. This one-way locking mechanism effectively fixes the angular position of the gear disc, thereby achieving reliable locking of the entire transmission system. Specifically, through... The fixing of the gear plate ensures the stability of the two plate assemblies; the fixing of the plate assemblies further constrains the displacement of the two side plates; the fixing of the side plates strengthens the constraint on the plate assemblies; ultimately, this series of interlocking fixing actions provides reliable auxiliary fixing support for the guide rail body; the mechanism, through the ingenious cooperation of one-way ratchet and pawl, realizes multi-level linkage fixing from the rotating shaft to the guide rail body, which not only ensures the reliable locking of the system in the set position, but also greatly simplifies the operation process; this design fully utilizes the advantages of mechanical transmission, making the entire fixing process both safe and reliable, as well as easy to operate, significantly improving the efficiency and convenience of the equipment.

[0016] The present invention is further configured such that: a shaft four, which is fixedly connected to a pawl, is rotatably connected inside each of the two protective covers; a toggle plate is fixedly connected to the end of each of the two shaft fours away from the guide rail body; and a torsion spring is sleeved on the outside of each of the two shaft fours.

[0017] Through the above technical solution, the core function of the actuating plate is to release the pawl from the one-way ratchet, achieving rapid unlocking of the system. When unlocking plate two is required, the operator only needs to deflect the actuating plate, which drives the connected shaft four to rotate. The rotation of shaft four further drives the pawl to deflect at an angle, causing the pawl to gradually disengage from the one-way ratchet. When the pawl is completely disengaged from the one-way ratchet, the system is unlocked. At this time, the pre-stressed tension spring immediately releases its stored elastic potential energy, and its rebound force drives plate two to smoothly return to its initial position. During this process, plate two completely disengages from the side plate, successfully completing the unlocking operation. After unlocking, the operator releases the lever, and under the elastic restoring force of the torsion spring, shaft four automatically returns to its original position. The reset motion of shaft four simultaneously drives the pawl to re-engage with the one-way ratchet, preparing for the next locking operation. This mechanism, through its ingenious mechanical linkage design, achieves both rapid unlocking and automatic reset. The entire operation is simple and intuitive, ensuring both ease of unlocking and automatic system recovery to the locked state, fully demonstrating the practicality and reliability of the mechanical design. This design not only improves operational efficiency but also ensures the stability and safety of the system through the rational use of elastic elements.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model achieves precise positioning and stable fixation of the guide rail body through a multi-level linkage mechanism, which has significant beneficial effects; the positioning mechanism enables rapid locking and unlocking of the guide rail, which is simple to operate and reliable in fixing; the opposing mechanism ensures automatic centering of the guide rail, and the adjustment process is smooth and precise, eliminating the need for repeated manual adjustments and significantly improving work efficiency; the limiting mechanism ensures the accuracy of the movement trajectory, effectively prevents deviation, and provides a restoring force, enhancing the stability of the system.

[0020] 2. This utility model achieves a one-way locking function through a one-way mechanism, preventing guide rail position deviation and ensuring the reliability of the fixed state; through the linkage design of the toggle plate and torsion spring, it achieves one-button quick unlocking and automatic reset, making operation convenient and safe; the various mechanisms work together, and through the ingenious cooperation of mechanical linkage and elastic elements, it not only ensures the ease of operation but also ensures the stability and accuracy of the system, significantly improving the efficiency and ease of operation of the equipment, and has high practical value and promotion significance.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figures 1-6This embodiment of a linear roller guide rail fixing mechanism includes a base 1, a guide rail body 2 placed on top of the base 1, blocks 3 fixedly connected to the front and rear ends of the guide rail body 2, and side plates 4, both located on top of the base 1, fixedly connected to the sides of the two blocks 3. Protective covers 5 are fixedly connected to the front and rear ends of the base 1, and a positioning mechanism 6 is slidably connected inside the protective covers 5. The positioning mechanism 6 includes multiple sleeves 601 fixedly connected to the two protective covers 5, and fixing blocks 602 slidably connected inside the multiple sleeves 601. The ends of the multiple fixing blocks 602 facing the blocks 3 are all inclined, and the bottoms of the multiple fixing blocks 602 are in contact with the tops of the side plates 4. Multiple fixing blocks 602 are fixedly connected to two shafts 603 that are slidably connected to the sleeve 601 at their ends away from block 3. Springs 604 are fitted around the outside of each shaft 603. L-shaped rods 605 passing through the sleeve 601 are fixedly connected to the ends of multiple fixing blocks 602 away from block 3. The core function of the positioning mechanism 6 is to achieve precise positioning and stable fixation of the guide rail body 2. When fixing the linear roller guide rail, the operator must first align the blocks 3 at both ends of the guide rail body 2 with the protective cover 5, while ensuring that the side plates 4 on both sides of block 3 are aligned with the inclined guide surfaces of the two sets of fixing blocks 602. Then, a vertically downward pressure is applied to block 3. The side plate 4 then moves downward and comes into contact with the inclined surface of the fixed block 602. As the downward pressing action continues, the side plate 4 transmits horizontal thrust to the fixed block 602 through the inclined surface contact, forcing the fixed block 602 to undergo axial displacement along the compression direction of the spring 604. During this process, the spring 604 is continuously compressed and stores energy until the side plate 4 completely passes over the inclined surface area of ​​the fixed block 602 and reaches its predetermined bottom position. When the side plate 4 completes its downward stroke, the compressed spring 604 immediately releases its elastic force, pushing the fixed block 602 to quickly return to its original position. At this time, the bottom plane of the returned fixed block 602 forms a stable contact with the top plane of the side plate 4, through the synergistic action of multiple sets of fixed blocks 602. The side plate 4 is subject to bidirectional limiting and locking, thereby effectively constraining block 3 through the fixation of the side plate 4, and finally achieving a stable fixation of the guide rail body 2. Through the cooperation of mechanical linkage and elastic elements, a fast and reliable one-button locking function is realized. During the unlocking operation, simply pull the L-shaped rod 605 along the axis to drive the fixing block 602 to overcome the resistance of the spring 604 and disengage from the contact surface with the side plate 4, thereby instantly releasing the constraint on the side plate 4, releasing block 3, and finally realizing the rapid unlocking of the guide rail body 2. This design, through the ingenious cooperation of the inclined plane transmission mechanism and the elastic reset device, not only ensures the simplicity of the operation process, but also ensures the mechanical stability in the fixed state.

[0030] like Figures 4-6As shown, a counter-mechanism 7 is rotatably connected inside the protective cover 5. The counter-mechanism 7 includes two rotating shafts 701 rotatably connected inside the two protective covers 5, respectively. Gear discs 702 are fixedly connected to the outside of the two rotating shafts 701, and racks 703 mesh at both the upper and lower ends of the two gear discs 702. Two plates 704 located on both sides of block 2 3 are slidably connected inside the two protective covers 5, and multiple plates 704 are fixedly connected to multiple racks 703. The core function of the counter-mechanism 7 is to realize the automatic centering adjustment of the guide rail body 2. To ensure it remains in a precise center position, the operator rotates handle 903, causing the connected rotating shaft 701 to rotate. The rotation of shaft 701 further drives the gear disc 702 to rotate synchronously, and this rotation is converted into linear movement of the upper and lower racks 703. It is particularly noteworthy that the two racks 703 always move in opposite directions, i.e., simultaneously towards the central gear disc 702. As the racks 703 move in opposite directions, the two plates connected to them... The two 704 components also undergo synchronous displacement, moving smoothly towards the gear plate 702. During the movement of the two 704 components, they gradually approach the side plates 4 on both sides. When the rotating shaft 701 reaches its maximum rotation angle and can no longer rotate, the two 704 components simultaneously achieve complete contact with the side plates 4 on both sides. This synchronous contact mechanism ensures that the two side plates 4 always maintain a perfect mirror symmetry relationship, and thus, through the symmetrical positioning effect of the side plates 4, the guide rail body 2 is precisely adjusted and fixed in the center position. The design advantage of this mechanism is that it realizes the automatic centering function of the guide rail body 2, eliminating the need for repeated manual adjustments. Precise centering adjustment can be achieved through simple rotation operations. This mechanical automatic adjustment method not only significantly improves work efficiency and reduces the labor intensity of operators, but also ensures the stability and accuracy of the adjustment process, providing a reliable guarantee for the precise positioning of the guide rail. The entire adjustment process is simple, quick, and intuitive, fully demonstrating the practicality and efficiency of the mechanical design.

[0031] like Figures 4-6As shown, a limiting mechanism 8 is slidably connected inside the protective cover 5. The limiting mechanism 8 includes multiple cylinders 801 fixedly connected to the two protective covers 5 respectively. A shaft 802 is slidably connected to the end of each cylinder 801 facing the block 3. The ends of the shafts 802 facing the block 3 are fixedly connected to multiple plates 704 respectively. Tension springs 803 are sleeved on the outside of each cylinder 801. The main function of the limiting mechanism 8 is to precisely limit and guide the movement of the plates 704. When the plates 704 are displaced, the shafts 802 connected to them will slide linearly within the inner cavity of the cylinders 801. Through the precisely fitted guide structure between the shafts 802 and the cylinders 801, the movement of the plates 704 is ensured. During movement, it strictly follows the preset straight-line trajectory, completely avoiding any form of deflection or offset, thus achieving high-precision motion guidance and reliable limiting guidance functions. At the same time, during the displacement of the plate 704 component, the tension spring 803 connected to it is simultaneously pulled, causing the tension spring 803 to undergo elastic deformation and store potential energy. This design not only ensures the smoothness of the movement of the plate 704 component, but also provides the necessary restoring force for the system through the elastic action of the tension spring 803, further enhancing the motion stability and control accuracy of the entire mechanism. The limiting mechanism 8, through the organic combination of mechanical guidance and elastic elements, achieves precise constraint and reliable control of the movement trajectory of the plate 704 component.

[0032] like Figures 4-6As shown, a one-way mechanism 9 is rotatably connected inside the protective cover 5. The one-way mechanism 9 includes two one-way ratchet wheels 901 fixedly connected to the outside of two rotating shafts 701. Pads 902 that mesh with the one-way ratchet wheels 901 are rotatably connected inside the two protective covers 5. A handle 903 is installed at the end of each rotating shaft 701 away from the guide rail body 2. The core function of the one-way mechanism 9 is to achieve precise positioning and one-way locking of the gear plate 702. When the operator drives the rotating shaft 701 to rotate, the rotating shaft 701 drives the gear plate 702 to rotate synchronously. The rotation of the gear plate 702 further drives the two plate assemblies 704 to move towards the side plates 4 on both sides. During this process, the rotational motion of the rotating shaft 701 is simultaneously transmitted to the one-way ratchet wheel 901 connected to it, causing the one-way ratchet wheel 901 to rotate accordingly. Under the mechanical limiting action of the pawl 902, the one-way ratchet wheel 901 can only move in one direction in the set direction. The mechanism rotates but cannot rotate in the opposite direction; this one-way locking mechanism effectively fixes the angular position of the gear disk 702, thereby achieving reliable locking of the entire transmission system; specifically, by fixing the gear disk 702, the positional stability of the two plate 2 704 assemblies is ensured; the fixing of the plate 2 704 assemblies further constrains the displacement of the two side plates 4; the fixing of the side plates 4 strengthens the constraint force on the block 2 assemblies; ultimately, this series of interlocking fixing actions provides reliable auxiliary fixing support for the guide rail body 2; the mechanism, through the ingenious cooperation of the one-way ratchet 901 and the pawl 902, achieves multi-level linkage fixing from the rotating shaft 701 to the guide rail body 2, which not only ensures reliable locking of the system in the set position, but also greatly simplifies the operation process; this design fully utilizes the advantages of mechanical transmission, making the entire fixing process both safe and reliable, and easy to operate, significantly improving the efficiency and ease of use of the equipment.

[0033] like Figures 4-6As shown, two protective covers 5 are respectively rotatably connected to shafts 904 fixedly connected to pawls 902. Each shaft 904 has a fixed actuating plate 905 at its end away from the guide rail body 2. Both shafts 904 are fitted with torsion springs 906. The core function of the actuating plate 905 is to release the pawl 902 from the one-way ratchet 901, enabling rapid unlocking of the system. When unlocking plate 704 is required, the operator only needs to deflect the actuating plate 905. This action causes the shaft 904 connected to it to rotate. The rotation of shaft 904 further drives the pawl 902 to deflect at an angle, causing the pawl 902 to gradually disengage from the one-way ratchet 901. When the pawl 902 is completely disengaged from the one-way ratchet 901, the system is unlocked. At this time, the pre-stressed tension spring 803 immediately releases its stored elastic potential energy. The spring force causes plate 704 to smoothly return to its initial position. During this process, plate 704 completely disengages from side plate 4, successfully completing the unlocking operation. After unlocking, the operator releases the toggle plate 905. At this time, under the elastic restoring force of torsion spring 906, shaft 904 automatically resets to its original position. The reset movement of shaft 904 simultaneously causes pawl 902 to re-engage with one-way ratchet 901, preparing for the next locking operation. This mechanism, through its ingenious mechanical linkage design, achieves the dual functions of rapid unlocking and automatic reset. The entire operation process is simple and intuitive, ensuring both the convenience of unlocking and the automatic return of the system to the locked state, fully demonstrating the practicality and reliability of the mechanical design. This design not only improves operational efficiency but also ensures the stability and safety of the system operation through the rational use of elastic elements.

[0034] In use, this utility model achieves precise positioning and fixation of the guide rail body 2 through multi-level linkage. During operation, pressing down on the blocks 3 at both ends of the guide rail body 2 causes the side plates 4 to push the inclined surface of the fixing block 602, compressing the spring 604 until the side plates 4 pass over the inclined surface. The spring 604 then rebounds, causing the fixing block 602 to lock the side plates 4, completing the initial fixation of the guide rail body 2. Then, rotating the handle 903 drives the rotating shaft 701, causing the gear plate 702 to drive the rack 703 to move towards each other, pushing the two side plates 704 closer to the center, automatically adjusting the guide rail body 2 to the center position. The one-way ratchet 901 and pawl 9 The coordination of 02 ensures that the rotating shaft 701 can only rotate in one direction, preventing the guide rail from shifting. The limiting function is achieved by the sliding of shaft 3 802 within cylinder 2 801, ensuring accurate movement trajectory. At the same time, tension spring 803 provides reset force. When unlocking, the toggle plate 905 is moved to disengage the pawl 902 from the one-way ratchet 901, and tension spring 803 pulls plate 2 704 to reset, releasing the guide rail from fixation. After releasing the toggle plate 905, torsion spring 906 automatically resets the pawl 902, preparing for the next locking. The entire process achieves fast and accurate positioning, fixing, and unlocking through the coordination of mechanical linkage and elastic elements.
