Description

Technical Field

[0001] The invention relates to the technical field of rolling linear guide pair linear guide rail installation, in particular to a rolling linear guide pair linear guide rail drilling and milling machine tool. Background Art

[0002] The linear guide of the rolling linear guide pair is mainly capable of bearing various loads such as vertical, horizontal and overturning moments from the slider to ensure that the moving parts can still run smoothly under load. For example, in the workbench of the machine tool, the linear guide can bear the weight of the workbench and the workpiece to ensure stability during the processing. The existing installation method fixes the guide rail to the mounting base through a pressure plate. The pressure plate is usually connected with bolts, which is convenient to install and disassemble. The installation accuracy of the guide rail can be fine-tuned by adjusting the position and tightening degree of the pressure plate. Applicable scenarios: Suitable for various types of machine tools, automation equipment, etc., especially for equipment that requires frequent maintenance and adjustment. The pressure plate installation method can easily replace and adjust the accuracy of the guide rail.

[0003] According to the Chinese invention patent, the published CN117469299A, a linear guide pair relates to the field of linear guide technology, and its installation method includes: first cleaning the working bed of the linear guide pair, placing the guide rail on the bed, tightening the positioning screws of the guide rail from the middle to both sides in sequence to make the guide rail fit the working reference surface, and then using a torque wrench to further tighten the guide rail positioning screws to complete the guide rail installation; then perform subsequent steps such as slider assembly. After the linear guide rail is installed, when the guide rail is installed in a specific area and both ends of the guide rail are blocked by obstacles, the movable slider on the guide rail is disassembled to facilitate inspection, oiling and ball replacement inside the slider.

[0004] However, the above patent cannot quickly locate during the installation process, which requires the position to be calibrated in advance before installation, which reduces the efficiency of the installation process. In addition, the above installation method is only suitable for single-rail installation. When the main rail and the auxiliary rail need to be installed together, it takes a lot of time, resulting in a decrease in overall work efficiency. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] During operation, the bottom of the main rail 4 is engaged with the clamping member 3. During engagement, the auxiliary rails 6 on both sides can be quickly deployed with the aid of the unfolding member 5. Subsequently, the clamping member 3 can be used to push the clamped main rail 4 left and right to achieve calibration. After calibration, it can be fixed with bolts, thereby increasing service life. When the distance between the auxiliary rails 6 and the main rail 4 at both ends needs to be adjusted, the adjusting member 7 can be used to adjust the distance between the auxiliary rails 6 and the main rail 4 on the side of the main rail 4, thereby improving usage efficiency.

[0031] See also Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The interior of the clamping part 3 includes a mounting seat 31, a sliding seat 32, a positioning hole 33, a connecting block 34, a movable pin 35 and a fixed pin 36. The mounting seats 31 are fixedly installed at both ends of the interior of the machine tool 1. The interior of the mounting seat 31 is movably sleeved with the sliding seat 32. The interiors of the sliding seat 32 and the mounting seat 31 are provided with penetrating positioning holes 33. The top of the sliding seat 32 is fixedly installed with the connecting block 34. The top of the connecting block 34 is fixedly installed with the fixing pin 36. The outer wall of the connecting block 34 is movably sleeved with the movable pin 35. The interior of the clamping part 3 also includes a card interface 37, a guide block 38, a connecting rod 39, a circular mouth 351, an insertion interface 352, a plug rod 361 and a delay roller 362. The top of the connecting block 34 is fixedly installed with a connecting rod 39. The top of the connecting rod 39 is fixedly connected to the bottom of the fixing pin 36. The interior of the movable pin 35 is provided with a circular mouth 351. The circumference of the circular mouth 351 The outer wall is provided with an insertion port 352, and the bottom circumference of the fixing pin 36 is fixedly installed with a plug rod 361, and the interior of the plug rod 361 is movably installed with a delay roller 362. The interior of the circular opening 351 and the outer wall of the connecting rod 39 are movably sleeved, and the bottom of the plug rod 361 and the interior of the insertion port 352 are adapted to each other. A card interface 37 is provided at the bottom of both ends of the main rail 4, and a sleeve cavity 371 is provided inside the two sides of the card interface 37. A rod A372 is fixedly installed inside the sleeve cavity 371, and the end of the rod A372 close to the card interface 37 is movably sleeved with a guide block 38. A spring A373 is movably sleeved on the outer wall of the rod A372, and an extrusion plate 374 is fixedly installed on the end of the guide block 38 away from the card interface 37. The end of the rod A372 close to the card interface 37 and the extrusion plate 374 are movably sleeved with the interior of the guide block 38, and the top of the guide block 38 close to the card interface 37 is sloped.

[0032] When engaging, the engaging interfaces 37 opened on both sides of the bottom of the main rail 4 can be engaged with the top of the fixing pin 36. When the fixing pin 36 extends into the interior of the engaging interface 37, it will fit with the outer wall of the guide block 38. At this time, the distance between the guide blocks 38 at both ends becomes wider, so that the guide block 38 and the extrusion plate 374 shrink along the outer wall of the rod A372 toward the interior of the sleeve cavity 371. During the shrinkage process, the spring A373 movably sleeved on the outer wall of the rod A372 will be squeezed, allowing the spring A373 to initially accumulate force. In the process of the above-mentioned guide block 38 shrinking toward the interior of the sleeve cavity 371, appropriate space will be freed up to allow the fixing pin 3 6 can extend to the top of the guide block 38, and at the same time, the guide block 38 will also move to the bottom of the fixed pin 36. At this time, the extrusion force on the guide block 38 disappears, and the spring A373 will reset. When resetting, it can effectively push the guide block 38 out of the inside of the sleeve cavity 371, so that the guide block 38 is clamped at the bottom of the fixed pin 36, forming a limit and completing the initial clamping. At this time, the sliding seat 32 can be pushed to move left and right inside the mounting seat 31. After adjusting to the appropriate position, it is aligned with the positioning hole 33 through the fixing hole opened in the main rail 4, and then fixed with bolts, so that angle calibration can be performed during the positioning process. , to improve work efficiency, when it is necessary to disassemble, first remove the above-mentioned bolts, then press the main rail 4 downward, at this time, the guide blocks 38 on both sides of the card interface 37 that are movably sleeved will continue to move downward, and in the process of movement, they will fit together with the outer wall of the movable pin 35, and at that time the distance will widen, causing the guide blocks 38 to shrink toward the inside of the sleeve cavity 371, so that the movable pin 35 can extend to the distance between the guide blocks 38 on both sides, and at this time, the main rail 4 is lifted to move upward, and the guide blocks 38 will clamp the movable pin 35 and move upward until the top of the movable pin 35 fits together with the bottom of the fixed pin 36 to form a cone, and then continue to lift it upward. The movable main rail 4 and the guide block 38 as a whole will move upward along the surface of the cone, thereby breaking away from the contact with the fixed pin 36, which is convenient for quick disassembly. It should be noted that during the plug-in process of the fixed pin 36 and the movable pin 35, the plug-in rod 361 will extend to the inside of the plug-in interface 352; when the guide block 38 moves to the connection between the movable pin 35 and the fixed pin 36, the delay roller 362 can increase the friction between the movable pin 35 and the fixed pin 36, thereby preventing the movable pin 35 from quickly breaking away from the contact between the movable pin 35 and the fixed pin 36 when moving to the connection, and thus preventing the cone from being formed, thereby preventing the situation where it cannot be quickly disassembled.

[0033] See also Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7The interior of the deployment member 5 includes a side tube 51, an internal rod 52, a positioning rod 53, a counterweight 54, a rod B55, a piston A56, an air cylinder 57 and an air supply pipe 59. The side surfaces of both ends of the main rail 4 are fixedly connected to the side tube 51. The internal part of the side tube 51 is movably connected to the internal rod 52. The side of the internal rod 52 away from the side tube 51 is connected to the positioning rod 53. The top of the card interface 37 is movably connected to the counterweight 54. The top of the counterweight 54 is fixedly installed with the rod B55. The top of the rod B55 is fixedly installed with the piston A56. The outer wall of the piston A56 is movably connected to the inside of the air cylinder 57, and the top of the air cylinder 57 is connected to the inside of the side tube 51 through the air supply pipe 59. The interior of the expansion member 5 further includes a mounting rod 510, a piston B511, an exhaust pipe 512, a moving cylinder 513, an outlet 514, a spring B515, a connecting plug 516 and a piston 517. The mounting rod 510 is fixedly installed inside the side cylinder 51, and the outer wall of the mounting rod 510 passes through the piston B511, and the outer wall of the piston B511 is movably connected to the interior of the side cylinder 51. The end of the built-in rod 52 away from the positioning rod 53 is fixedly connected to the interior of the piston B511. An exhaust pipe 512 is provided at the bottom of the mounting rod 510, and the two ends of the exhaust pipe 512 are respectively connected to the piston B511 and the moving cylinder 513. The built-in rod 52 is away from the gas pipe 59. An outlet 514 is provided inside one side, a spring B515 is wound around the circumference of the end of the mounting rod 510 away from the piston B511, a connecting plug 516 is movably sleeved on the side of the moving cylinder 513 away from the exhaust pipe 512, a piston 517 is fixedly installed on the side of the connecting plug 516 close to the mounting rod 510, the interior of the piston 517 and the interior of the moving cylinder 513 are adapted to each other, and the interior of the piston 517 is fixedly connected to the outer wall of the end of the mounting rod 510 away from the piston B511, the interior of the built-in rod 52 includes a delivery pipe 518, a pressurizing chamber 519, a piston D520, an adjusting rod 521, a limiting groove 522, a built-in groove 523 and a rolling wheel 524, and the piston B5 11 and the internal embedded rod 52 are installed with a delivery pipe 518, the end of the delivery pipe 518 away from the piston B511 is fixedly connected to the boost chamber 519, the side of the boost chamber 519 away from the delivery pipe 518 is provided with a piston D520, the outer wall of the piston D520 is movably connected to the inside of the built-in rod 52, the side of the piston D520 away from the boost chamber 519 is fixedly connected to the adjustment rod 521, a plurality of limiting grooves 522 are provided on the top of the adjustment rod 521, and built-in grooves 523 are provided on both sides of the adjustment rod 521. The internal movably connected rolling wheels 524 are connected to the built-in grooves 523, and the end of the adjustment rod 521 away from the piston D520 is fixedly connected to the positioning rod 53.

[0034] When the main rail 4 is connected, the top of the fixing pin 36 pushes the counterweight 54 to move upward. At this time, the rod B55 and the piston A56 fixedly connected to the counterweight 54 will move upward synchronously along the inside of the gas storage cylinder 57, thereby squeezing the gas stored on the top. The squeezed gas is transported to the inside of the side cylinder 51 through the gas pipe 59 and accumulates on the side of the piston B511, increasing the gas density. As the gas density increases, the piston B511 is pushed forward, and the built-in rod 52 fixedly connected to the piston B511 also extends out from the inside of the side cylinder 51, prompting the auxiliary rail 6 fixedly connected to the side cylinder 51 and the positioning rod 53 to quickly unfold.

[0035] As the piston B511 moves forward, it will fit in with the moving cylinder 513. The thrust generated when the two fit together pushes the moving cylinder 513 forward and extends through the outlet 514, while the piston 517 and the connecting plug 516 remain stationary. When the moving cylinder 513 moves forward, the gas inside it is compressed, and the compressed gas is transported to the delivery pipe 518 embedded in the piston B511 through the exhaust pipe 512, and then transported to the internal storage of the boosting chamber 519 through the delivery pipe 518. When the gas is stored in the boosting chamber 519, a preliminary thrust will be formed through the side surface inside the piston D520. In addition, when the moving cylinder 513 extends out from the inside of the outlet 514, the spring B515 retained in the moving cylinder 513 will squeeze the piston 517 against each other to achieve initial force storage.

[0036] See also Figure 1 、 Figure 7 、 Figure 8, the interior of the adjusting member 7 includes a limit box 71, a gas limit tube 72, a gas collecting box 73, a pull rod 74, a movable plate 75, a push rod 76, a rod D77, a spring F78, a limit ring 79 and nitrogen 710. The built-in rod 52 is fixedly installed with the limit box 71 near the top of the positioning rod 53. The top of the limit box 71 is fixedly connected to the gas collecting box 73 through the gas limit tube 72, and the outer wall of the gas collecting box 73 is fixedly connected to the outer wall of one end of the main rail 4. The internal movable sleeve of the gas collecting box 73 is connected to the pull rod 74, and the internal movable sleeve of the limit box 71 is connected to the movable plate 75. The bottom of the movable plate 75 is fixedly installed with the push rod 76, and the bottom of the push rod 76 passes through the limit box 71 and the built-in rod 52 and extends to the limit Inside the positioning groove 522, a rod D77 is set on the side of the push rod 76, and the outer wall of the rod D77 is movably wound with a spring F78. The top of the rod D77 passes through the movable plate 75 and is fixedly connected to the limiting ring 79. The top of the movable plate 75 is filled with nitrogen 710. The outer wall of the pull rod 74 is fixedly connected to the piston G712. The outer wall of the piston G712 and the inner part of the gas collection box 73 are movably connected. The side of the piston G712 close to the pull rod 74 is fitted with the spring G711. The outer wall of the spring G711 and the outer wall of the pull rod 74 are intertwined with each other. The gas collection box 73 is opened on the side away from the pull rod 74 with two symmetrical inlet ports 713. The interior of the inlet port 713 is fixedly connected to the outer wall of the gas limiting tube 72.

[0037] When the length of the auxiliary rail 6 needs to be adjusted, the pull rod 74 is pulled outward, and the piston G712 fixedly connected thereto will move in the direction away from the inlet port 713. This action will cause the nitrogen 710 stored in the top of the limit box 71 to be recovered into the gas collection box 73 through the gas limit tube 72, thereby releasing the limit on the top of the movable plate 75. At this time, with the help of the thrust generated by the side of the piston D520, the adjusting rod 521 is able to move forward. During the forward movement, the adjusting rod 521 uses the slope of the bottom side of the supporting rod 76 to disengage the supporting rod 76 from the inside of the limiting groove 522. When the supporting rod 76 slides out, it will drive the movable plate 75 to move upward, so that the spring F78 that is in contact with the movable plate 75 is subjected to initial squeezing force. When the supporting rod 76 moves to the inside of the next limiting groove 522, the spring F78 generates a rebound force, pushing the movable plate 75 downward. The push rod 76 is engaged in the limit groove 522. After the length adjustment is completed, stop pulling the pull rod 74, and the reset force generated by the spring G711 will push the piston G712 back to its original position. At this time, the nitrogen 710 stored in the gas collection box 73 will be transported to the limit box 71 again, and the movable plate 75 will be limited again to prevent the push rod 76 from driving the movable plate 75 to move upward during the pushing process. It is worth noting that rolling wheels 524 are movably installed on both sides of the adjustment rod 521. This design can effectively reduce the friction when the adjustment rod 521 extends forward, which is convenient for quick adjustment. If the length needs to be shortened, just perform the reverse operation. In addition, when the main rail 4 is pulled out from the fixing pin 36, the spring B515 will reset and push the movable cylinder 513 back to its initial position. At the same time, the exhausted gas will be drawn into the interior of the movable cylinder 513, providing convenience for subsequent disassembly work.

[0038] See also Figure 4 and Figure 7 , the two sides of the delay roller 362 are fixedly connected with a connecting shaft, and the outer wall of the connecting shaft is movably sleeved with a torsion spring. The connecting shaft and the torsion spring are both located on both sides of the inside of the plug-in rod 361, and a connecting port is opened inside the side of the built-in rod 52 away from the piston B511. The inside of the connecting port is movably sleeved with the outer wall of the adjusting rod 521, and the diameter of the piston D520 is twice the diameter of the connecting port. Through the torsion spring, the torsion spring provides a reverse force during the rotation of the connecting shaft, which can delay the speed of separation of the movable pin 35 and the fixed pin 36, facilitating quick disassembly. The connecting port can ensure that the adjusting rod 521 can extend and retract freely, and can also ensure that the piston D520 is out of contact, which is convenient for limiting and movement.

[0039] Working principle: When in use,

[0040] Step 1: Principle of snap-in and preliminary positioning

[0041] When the card interfaces 37 on both sides of the bottom of the main rail 4 are engaged with the top of the fixing pin 36, the fixing pin 36 extends into the inside of the card interfaces 37 and fits into the outer wall of the guide block 38, causing the distance between the guide blocks 38 at both ends to widen, so that it and the extrusion plate 374 shrink along the outer wall of the rod A372 toward the inside of the sleeve cavity 371, and the spring A373 that is movably sleeved on the outer wall of the extrusion rod A372 realizes initial force storage. After the guide block 38 shrinks to make room, the fixing pin 36 extends to the top of the guide block 38, and the guide block 38 moves to the bottom of the fixing pin 36. At this time, the squeezing force of the guide block 38 disappears, and the spring A373 resets and pushes the guide block 38 out of the sleeve cavity 371, so that it is engaged with the bottom of the fixing pin 36 to form a limit. After the initial engagement is completed, the sliding seat 32 is pushed left and right in the mounting seat 31 to adjust the position, align the internal fixing hole of the main rail 4 with the positioning hole 33, and fix it with bolts to calibrate the angle to improve work efficiency.

[0042] Step 2: Gas storage and thrust formation principle

[0043] The piston B511 moves forward and fits into the moving cylinder 513. The thrust generated pushes the moving cylinder 513 to extend forward through the outlet 514. The piston 517 and the connecting plug 516 remain stationary. After the gas inside the moving cylinder 513 is compressed, it is transported to the internal delivery pipe 518 of the piston B511 through the exhaust pipe 512, and then enters the boost chamber 519 for storage. During storage, a preparatory thrust is formed through the side of the piston D520. At the same time, when the moving cylinder 513 extends from the outlet 514, the spring B515 retained inside is squeezed with the piston 517 to achieve initial force storage.

[0044] Step 3: Length adjustment and reset principle

[0045] When adjusting the length of the auxiliary rail 6, the pull rod 74 is pulled outward, and the piston G712 fixed to it is away from the inlet 713, so that the nitrogen 710 stored at the top of the limit box 71 is recovered to the gas collection box 73 through the gas limit pipe 72, and the limit on the top of the movable plate 75 is released. With the help of the side thrust of the piston D520, the adjustment rod 521 moves forward, and the bottom slope of the push rod 76 is used to make the push rod 76 slide out of the limit groove 522, driving the movable plate 75 to move upward to squeeze the spring F78. When the push rod 76 moves to the next limit groove 522, the rebound force of the spring F78 pushes Move the movable plate 75 downward so that the push rod 76 is engaged in the limit groove 522. After the adjustment is completed, stop pulling the pull rod 74. The reset force of the spring G711 pushes the piston G712 back. The nitrogen 710 in the gas collection box 73 is transported to the limit box 71, and the movable plate 75 is re-positioned. The rolling wheels 524 movably installed on both sides of the adjustment rod 521 can reduce the extension friction and facilitate adjustment. The operation is reversed when shrinking. When the main rail 4 is pulled out from the fixed pin 36, the spring B515 resets and pushes back the movable cylinder 513, and the exhaust gas is drawn into the movable cylinder 513 to facilitate subsequent disassembly.
