Description

TECHNICAL FIELD

[0002] The linear guide rail of the rolling linear guide rail pair can mainly bear various loads such as vertical direction, horizontal direction and overturning moment from the sliding block, and ensure that the moving part can still run smoothly under load, for example, in the workbench of the machine tool, the linear guide rail can bear the weight of the workbench and the workpiece, and ensure the stability during the machining process. The existing installation method fixes the guide rail on the installation base through a pressing plate, the pressing plate is usually connected by bolts, the installation and disassembly are relatively convenient, and the installation precision of the guide rail can be fine-tuned by adjusting the position and tightening degree of the pressing plate. Application scenarios: suitable for various types of machine tools, automation equipment, etc., especially for equipment that needs to be frequently maintained and adjusted, the pressing plate installation method can conveniently replace and adjust the precision of the guide rail.

[0003] According to the published CN117469299A of the Chinese invention patent, a linear guide rail pair relates to the technical field of linear guide rails, and the installation method comprises the following steps: first, cleaning the linear guide rail pair workbench, placing the guide rail on the workbench, sequentially tightening the positioning screws of the guide rail from the middle to both sides, making the guide rail fit the work reference surface, and further tightening the guide rail positioning screws with a torque wrench to complete the guide rail installation; then, performing the sliding block assembly and subsequent steps. After the linear guide rail is installed, in the case that the guide rail is installed in a specific area and the two ends of the guide rail are blocked by obstacles, the moving sliding block on the guide rail is disassembled to facilitate the inspection, oiling and replacement of the rolling balls in the sliding block.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-8 The present application provides a rolling linear guide rail pair linear guide rail drilling and milling hole processing machine tool technical scheme: a rolling linear guide rail pair linear guide rail drilling and milling hole processing machine tool, which comprises a machine tool 1, a drill bit 2 is fixedly installed in the middle of the machine tool 1, a clamping piece 3 is fixedly installed inside the machine tool 1, a main rail 4 is clamped on the top of the clamping piece 3, an auxiliary rail 6 is movably connected to the main rail 4 through an unfolding piece 5, and an adjusting piece 7 is fixedly installed on the top of the unfolding piece 5.

[0026] In the working process, the bottom of the main rail 4 is clamped with the clamping piece 3, and when clamping, the two side auxiliary rails 6 can be quickly unfolded by means of the unfolding piece 5; then, the clamping piece 3 can push the clamped main rail 4 left and right to realize calibration, and after calibration, the bolt can be fixed to improve the service life; when the distance between the auxiliary rail 6 and the main rail 4 needs to be adjusted, the adjusting piece 7 can be used to adjust the distance between the auxiliary rail 6 and the main rail 4 on the side of the main rail 4, thereby improving the use efficiency.

[0027] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , the inside of the clamping piece 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, both ends of the machine tool 1 are fixedly installed with the mounting seat 31, the inside of the mounting seat 31 movably sheaths the sliding seat 32, the inside of the sliding seat 32 and the mounting seat 31 is provided with a through positioning hole 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 fixed pin 36, the outer wall of the connecting block 34 movably sheaths the movable pin 35, the inside of the clamping piece 3 further includes a clamping port 37, a guide block 38, a connecting rod 39, a round port 351, an insertion port 352, an insertion rod 361 and a delay roller 362, the top of the connecting block 34 is fixedly installed with the connecting rod 39, the top of the connecting rod 39 and the bottom of the fixed pin 36 are fixedly connected, the inside of the movable pin 35 is provided with a round port 351, the circumferential outer wall of the round port 351 is provided with an insertion port 352, the bottom of the fixed pin 36 is fixedly installed with an insertion rod 361, the inside of the insertion rod 361 movably installs a delay roller 362, the inside of the round port 351 and the outer wall of the connecting rod 39 movably sheath, the bottom of the insertion rod 361 and the inside of the insertion port 352 are matched with each other, both ends of the main rail 4 are provided with a clamping port 37, both sides of the clamping port 37 are provided with a sleeve cavity 371, the inside of the sleeve cavity 371 is fixedly installed with a rod A 372, the end of the rod A 372 close to the clamping port 37 movably sheaths a guide block 38, the outer wall of the rod A 372 movably sheaths a spring A 373, the end of the guide block 38 away from the clamping port 37 is fixedly installed with a pressing plate 374, the end of the rod A 372 close to the clamping port 37 and the inside of the pressing plate 374 movably sheath the guide block 38, and the top of the guide block 38 close to the clamping port 37 is inclined.

[0028] During engagement, the locking interfaces 37 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 locking interface 37, it will fit against the outer wall of the guide block 38. At this time, the distance between the two guide blocks 38 widens, causing the guide block 38 and the pressing plate 374 to retract along the outer wall of the rod A372 into the cavity 371. During the retraction process, the spring A373, which is movably sleeved on the outer wall of the rod A372, will be compressed, allowing the spring A373 to initially store force. During the retraction of the guide block 38 into the cavity 371, a suitable space will be created, allowing the fixing pin 36 to... 6 can extend to the top of the guide block 38, and at the same time, the guide block 38 will move to the bottom of the fixing pin 36. At this time, the compressive force on the guide block 38 disappears, and the spring A373 will reset. During the reset, it can effectively push the guide block 38 out of the cavity 371, so that the guide block 38 is locked at the bottom of the fixing pin 36, forming a limit and completing the initial locking. 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 fixing hole and positioning hole 33 opened inside the main rail 4, and then fixed with bolts. Thus, angle calibration can also be performed during the positioning process. To improve work efficiency, when disassembly is required, first remove the aforementioned bolts, then press down on the main rail 4. At this time, the guide blocks 38 that are movably sleeved on both sides inside the locking interface 37 will continue to move downward. During the movement, they will fit against the outer wall of the movable pin 35, widening the gap and causing the guide blocks 38 to contract into the cavity 371. This allows the movable pin 35 to extend to the distance between the guide blocks 38 on both sides. Then, lift the main rail 4 upward, and the guide blocks 38 will clamp the movable pin 35 upward until the top of the movable pin 35 fits against the bottom of the fixed pin 36, forming a cone. Then, continue to lift upward. The main guide rail 4 and guide block 38 move upward along the surface of the cone, thus disengaging from the fixed pin 36 for easy and quick disassembly. It should be noted that during the insertion of the fixed pin 36 and the movable pin 35, the insertion rod 361 extends into the interior of the insertion interface 352. When the guide block 38 moves to the connection point of the movable pin 35 and the fixed pin 36, the delay roller 362 increases the friction between the movable pin 35 and the fixed pin 36, preventing the movable pin 35 from quickly disengaging from the contact point when it moves to the connection point, thus preventing the formation of a cone and avoiding situations where quick disassembly is not possible.

[0029] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7The inside of the unfolding piece 5 comprises a side cylinder 51, an inner rod 52, a positioning rod 53, a counterweight 54, a rod B 55, a piston A 56, an air cylinder 57 and a gas delivery pipe 59. The two ends of the main rail 4 are fixedly connected with the side cylinder 51. The inside of the side cylinder 51 movably sheaths the inner rod 52. The side, away from the side cylinder 51, of the inner rod 52 is fixedly connected with the positioning rod 53. The top of the clamping interface 37 movably sheaths the counterweight 54. The top of the counterweight 54 is fixedly installed with the rod B 55. The top of the rod B 55 is fixedly installed with the piston A 56. The outer wall of the piston A 56 movably sheaths the inside of the air cylinder 57. The top of the air cylinder 57 is in communication with the inside of the side cylinder 51 through the gas delivery pipe 59. The inside of the unfolding piece 5 further comprises an installation rod 510, a piston B 511, an exhaust pipe 512, a moving cylinder 513, an outlet 514, a spring B 515, a connecting plug 516 and a piston 517. The inside of the side cylinder 51 is fixedly installed with the installation rod 510. The outer wall of the installation rod 510 penetrates the piston B 511. The outer wall of the piston B 511 movably sheaths the inside of the side cylinder 51. The end, away from the positioning rod 53, of the inner rod 52 is fixedly connected with the inside of the piston B 511. The bottom of the installation rod 510 is provided with the exhaust pipe 512. The two ends of the exhaust pipe 512 are in communication with the piston B 511 and the moving cylinder 513 respectively. The side, away from the gas delivery pipe 59, of the inner rod 52 is internally provided with the outlet 514. The end, away from the piston B 511, of the installation rod 510 is circumferentially wound with the spring B 515.

The inside of the piston 517 is fixedly connected with the outer wall of the end, away from the piston B 511, of the installation rod 510.

[0030] When the main rail 4 is completed, the top of the fixed pin 36 will push the weight 54 to move upward, at this time, the rod B55 and the piston A56 fixedly connected with the weight 54 will move upward synchronously along the inside of the gas cylinder 57, and then the gas stored at the top is extruded, the extruded gas is transported to the inside of the side cylinder 51 through the gas pipe 59, and is accumulated at the side of the piston B511, so that the gas density is increased, and as the gas density is increased, the piston B511 is pushed to move forward, and the built-in rod 52 fixedly connected with the piston B511 is also extended out of the inside of the side cylinder 51, so as to promote the side cylinder 51 and the positioning rod 53 to be fixedly connected with the secondary rail 6 to be quickly unfolded.

[0031] In the process of the piston B511 moving forward, it will be attached to the moving cylinder 513, and the push force generated when the two are attached will push the moving cylinder 513 to move forward and extend out 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 is compressed, the compressed gas is transported to the inside of the delivery pipe 518 inlaid in the piston B511 through the exhaust pipe 512, and then is transported to the inside of the booster cavity 519 for storage, when the gas is stored in the booster cavity 519, a preliminary push force is formed through the side of the piston D520, in addition, when the moving cylinder 513 extends out of the inside of the outlet 514, the spring B515 remaining in the inside of the moving cylinder 513 will be extruded with the piston 517, so as to achieve preliminary force storage.

[0032] Please refer to Figure 1 、 Figure 7 、 Figure 8The inside of the adjusting piece 7 comprises a limiting box 71, a gas limiting pipe 72, a gas collecting box 73, a pull rod 74, a movable plate 75, a resisting rod 76, a rod D 77, a spring F 78, a limiting ring 79 and nitrogen 710; the limiting box 71 is fixedly installed on the top of the built-in rod 52 close to the positioning rod 53; the top of the limiting box 71 is fixedly connected with the gas collecting box 73 through the gas limiting pipe 72, and the outer wall of the gas collecting box 73 is fixedly connected with one end of the outer wall of the main rail 4; the pull rod 74 is movably sleeved in the inside of the gas collecting box 73; the movable plate 75 is movably sleeved in the inside of the limiting box 71; the bottom of the resisting rod 76 is fixedly installed on the bottom of the movable plate 75; the bottom of the resisting rod 76 extends to the inside of the limiting groove 522 through the limiting box 71 and the built-in rod 52; the side of the resisting rod 76 is provided with the rod D 77; the outer wall of the rod D 77 movably winds the spring F 78; the top of the rod D 77 penetrates through the movable plate 75 and is fixedly connected with the limiting ring 79; the top of the movable plate 75 is filled with the nitrogen 710; the outer wall of the pull rod 74 is fixedly connected with a piston G 712; the outer wall of the piston G 712 movably sleeves in the inside of the gas collecting box 73; the piston G 712 is close to one side of the pull rod 74 and is abutted and connected with a spring G 711; the outer wall of the spring G 711 and the outer wall of the pull rod 74 are mutually wound; two symmetric inlet ports 713 are arranged on the side of the gas collecting box 73 away from the pull rod 74; the inside of the inlet port 713 is fixedly connected with the outer wall of the gas limiting pipe 72.

[0033] When the length of the auxiliary rail 6 needs to be adjusted, the pull rod 74 is pulled outwards, and the piston G712 fixedly connected therewith moves away from the inlet 713, which makes the nitrogen gas 710 stored at the top of the limiting box 71 flow back to the gas collecting box 73 through the gas limiting pipe 72, thereby releasing the limitation on the top of the movable plate 75. At this time, the adjusting rod 521 moves forward under the pushing force generated on the side of the piston D520. In the process of moving forward, the adjusting rod 521 uses the slope on the side of the bottom of the abutting rod 76 to make the abutting rod 76 slide out of the limiting groove 522. When the abutting rod 76 slides out, it drives the movable plate 75 to move upwards, so that the spring F78 attached to the movable plate 75 is subjected to a preliminary extrusion force. When the abutting rod 76 moves to the next limiting groove 522, the spring F78 generates a rebound force to push the movable plate 75 downwards, so that the abutting rod 76 is clamped in the limiting groove 522, and the length adjustment is completed. After stopping pulling the pull rod 74, the reset force generated by the spring G711 pushes the piston G712 back to the original position. At this time, the nitrogen gas 710 stored in the gas collecting box 73 is delivered to the limiting box 71 again, so as to limit the movable plate 75 again and prevent the abutting rod 76 from driving the movable plate 75 to move upwards during the pushing process. It is worth noting that the rolling wheels 524 are movably installed on both sides of the adjusting rod 521. This design can effectively reduce the friction when the adjusting rod 521 extends forward, so as to facilitate rapid adjustment. If the length needs to be shortened, the reverse operation is performed. In addition, when the main rail 4 is pulled out of the fixed pin 36, the spring B515 resets to push the moving cylinder 513 back to the initial position, and the discharged gas is sucked into the moving cylinder 513, which facilitates the subsequent disassembly work.

[0034] Please refer to Figure 4 and Figure 7 The connecting shaft is fixedly connected with the delay roller 362 on both sides, the outer wall of the connecting shaft movably sheathes the torsional spring, the connecting shaft and the torsional spring are located on both sides in the plug-in rod 361, the connecting hole is formed in the side of the built-in rod 52 away from the piston B511, the inside of the connecting hole movably sheathes the outer wall of the adjusting rod 521, and the diameter of the piston D520 is twice the diameter of the connecting hole. The torsional spring provided in the connecting shaft provides a reverse force during rotation, which can delay the speed at which the movable pin 35 and the fixed pin 36 are separated, facilitating quick disassembly. The connecting hole provided can ensure that the adjusting rod 521 can freely extend and contract, and also ensure that the piston D520 is out of contact, facilitating limitation and movement.

[0035] Working principle: in use,

[0036] Step one: clamping and preliminary positioning principle

[0037] When the clamping interfaces 37 on both sides of the bottom of the main rail 4 are clamped with the fixed pins 36 on the top, the fixed pins 36 extend into the clamping interfaces 37 and are attached to the outer wall of the guide blocks 38, which makes the distance between the two ends of the guide blocks 38 wider, so that they and the extrusion plate 374 shrink along the outer wall of the rod A 372 into the sleeve cavity 371, and the spring A 373 that is movably sleeved on the outer wall of the rod A 372 realizes preliminary force storage. After the guide blocks 38 shrink and leave space, the fixed pins 36 extend to the top of the guide blocks 38, and the guide blocks 38 move to the bottom of the fixed pins 36. At this time, the extrusion force of the guide blocks 38 disappears, and the spring A 373 resets to push the guide blocks 38 out of the sleeve cavity 371, so that they are clamped at the bottom of the fixed pins 36 to form a limit, and the preliminary clamping is completed. After the preliminary clamping is completed, the sliding seat 32 is pushed to move left and right in the mounting seat 31 to adjust the position, the fixed holes in the main rail 4 are aligned with the positioning holes 33, and the angle is calibrated by bolting to improve work efficiency.

[0038] Step two: gas storage and thrust formation principle

[0039] The forward movement of the piston B 511 is attached to the moving cylinder 513, generating a pushing force to push the moving cylinder 513 to extend forward through the outlet 514. The piston 517 and the connecting plug 516 remain stationary. The gas in the moving cylinder 513 is compressed and delivered to the delivery pipe 518 in the piston B 511, and then enters the booster cavity 519 for storage. At the same time, the spring B 515 inside the moving cylinder 513 is extruded by the piston 517 to achieve preliminary force storage.

[0040] Step three: length adjustment and reset principle

[0041] When adjusting the length of the auxiliary rail 6, pull the pull rod 74 outward, and the fixedly connected piston G 712 moves away from the inlet 713, so that the nitrogen gas 710 stored at the top of the limiting box 71 is recovered to the gas collection box 73 through the gas limiting pipe 72, and the limiting of the top of the movable plate 75 is removed. With the side thrust of the piston D 520, the adjusting rod 521 moves forward, and the slope at the bottom of the stopper 76 makes the stopper 76 slide out of the limiting groove 522, driving the movable plate 75 to move upward and extruding the spring F 78. When the stopper 76 moves to the next limiting groove 522, the spring F 78 pushes the movable plate 75 downward, so that the stopper 76 is clamped in the limiting groove 522. After the adjustment is completed, stop pulling the pull rod 74, and the reset force of the spring G 711 pushes the piston G 712 back, so that the nitrogen gas 710 in the gas collection box 73 is delivered to the limiting box 71 to re-limit the movable plate 75. The rolling wheels 524 movably installed on both sides of the adjusting rod 521 can reduce the extension friction, facilitating adjustment. When the main rail 4 is pulled out of the fixed pin 36, the spring B 515 resets to push back the moving cylinder 513, and the exhaust gas is drawn into the moving cylinder 513, facilitating subsequent disassembly.
