Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and in particular to a reference correction device and correction method for a chip removal guide rail of a machine tool. Background Art

[0002] The chip guide rail of a machine tool is a key component for efficiently removing cutting waste in CNC machine tools, machining centers and other equipment. It is mainly used to quickly remove chips from the machine tool. The chip guide rail of a machine tool is usually equipped with a reference correction device to correct and calibrate the position of the chip guide rail in real time to prevent the chip guide rail from offsetting and affecting the normal transportation of chips. Existing reference correction devices use a variety of methods to achieve the correction of chip removal guide rails, such as a double-sided double-opening automatic chip removal guide rail for machine tools with publication number CN104440124A, which includes a base, a combined guide rail base block is provided above the base, and chip removal guide rails are symmetrically provided at the front and rear ends of the upper part of the base along the length direction parallel to the base. Reference correction devices are symmetrically provided at the front and rear of the base, and the front and rear parts of the combined guide rail base block pass through the chip removal guide rails respectively. The combined guide rail base block and the chip removal guide rails are in sliding cooperation, and the front and rear parts of the combined guide rail base block are in rolling cooperation with the reference correction device. The existing reference correction device can usually only realize independent adjustment of the positions of multiple guide rail blocks on the chip removal guide rail, but cannot realize the overall correction of the chip removal guide rail. As a result, if the chip removal guide rail is deviated as a whole, it cannot be corrected. For example, the above-mentioned prior art uses the extrusion of the correction beam and the end roller to realize the separate adjustment of the left and right guide rail blocks, thereby realizing the overall correction. This correction method is not only low in accuracy and cannot realize real-time adjustment, but also the positions of the left and right guide rail blocks cannot be accurately determined. At the same time, the overall correction of the chip removal guide rail cannot be realized. The chip removal guide rail is prone to overall external deviation during long-term transportation, affecting the normal transportation of machine tool chips, and has certain limitations. Therefore, it is urgent to design a reference correction device and correction method for the chip removal guide rail of a machine tool to solve the above problems. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1: Reference Figure 1-Figure 2 A reference correction device for a chip removal guide rail of a machine tool includes a chip removal inclined guide box 2 arranged on a chip removal bottom box 1, a support box 3 is arranged on the chip removal inclined guide box 2, and a discharge box for discharging chips is arranged on the support box 3.

[0024] A movable frame 5 is provided at the lower part of the support box 3. The movable frame 5 plays the role of auxiliary support and can facilitate the overall movement of the chip removal guide rail to achieve rapid adjustment of the chip removal position.

An internal adjustment unit is provided in the conveying box 10. The conveying guide rail 8 is located between the chip removal bottom box 1, the chip removal inclined guide box 2 and the support box 3. It is used to convey the machine tool chips collected in the chip removal bottom box 1 to the support box 3 through the chip removal inclined guide box 2, and discharge them through the discharge box on the support box 3, thereby completing the rapid conveying and discharge of the machine tool chips.

[0026] The chip removal bottom box 1 is provided with a collection bucket 6 for assisting in collecting chips. The collection bucket 6 cooperates with the chip removal port of the machine tool to transfer the chips generated when the machine tool is working to the conveying guide rail 8 in the conveying box 10, thereby improving the conveying efficiency of the chips and preventing the chips from falling during conveying.

[0027] A control box 7 is provided on the chip removal inclined guide box 2, and the control box 7 is used to control the opening and closing and operating status of the driving unit, the external adjustment unit, and the internal adjustment unit to realize the automatic correction of the chip removal guide rail.

[0028] Example 2: Reference Figure 1-Figure 3 as well as Figure 9-10The technical solution of this embodiment is different from that of the first embodiment in that the driving unit includes a conveying motor 4 fixedly mounted on the upper portion of the support box 3, a driving wheel is rotatably mounted in the support box 3, and a transmission belt is provided between the driving end of the conveying motor 4 and the driving wheel; When the conveying motor 4 is started, it will drive the driving wheel to rotate through the cooperation of the transmission belt; The conveying box 10 is rotatably provided with a side wheel 20, and the conveying guide rail 8 is sleeved between the side wheel 20 and the driving wheel. The conveying box 10 is rotatably provided with a center wheel 23 that cooperates with the conveying guide rail 8. When the driving wheel rotates, it will drive the conveying guide rail 8 with the cooperation of the side wheel 20, and realize the transmission of the conveying guide rail 8 with the support of the middle wheel 23, so that the conveying guide rail 8 can be transmitted and transported between the chip removal bottom box 1, the chip removal inclined guide box 2 and the support box 3, and then the machine tool debris is transported and discharged during the transmission process, realizing automatic chip removal of the machine tool debris.

[0029] The conveying guide rail 8 is provided with a plurality of conveying rollers 9 for assisting chip removal. The conveying rollers 9 serve to separate the machine tool chips and at the same time increase the friction between the machine tool chips and the conveying guide rail 8 to prevent the machine tool chips from slipping during upward conveyance.

[0030] Example 3: Reference Figure 2-Figure 8 The difference between this embodiment and the second embodiment is that: a sliding component and an adjusting component are provided in the outer adjustment unit, wherein the sliding component is used to realize the position sliding of the conveying box 10; The sliding assembly includes a plurality of positioning seats 13 fixedly mounted on the chip removal bottom box 1, each positioning seat 13 is slidably mounted with a sliding rod 14, and the upper portion of each sliding rod 14 is fixedly mounted on the bottom of the conveying box 10; Multiple sliding rods 14 slide in the corresponding positioning seats 13, and multiple sliding rods 14 are arranged at the lower part of the conveying box 10, so that the conveying box 10 can perform corresponding horizontal sliding in the chip removal bottom box 1, thereby facilitating the reference correction of the horizontal lateral position of the conveying box 10.

[0031] On the right side (see the instruction manual). Figure 6 A linkage plate 16 is fixedly mounted on multiple sliding rods 14 (shown on the outer side), so that the multiple sliding rods 14 and the linkage plate 16 can be linked as a whole, that is, when the linkage plate 16 moves, it will drive the multiple sliding rods 14 to move as a whole, and then the cooperation of the multiple sliding rods 14 will drive the conveying box 10 to move as a whole, thereby realizing the position adjustment of the conveying box 10.

[0032] In a further embodiment, a laser emitter 15 for correcting the position of the conveying box 10 is provided in the adjustment assembly, two laser emitters 15 are fixedly mounted on the bottom of the conveying box 10, and two laser receiving plates 12 cooperating with the corresponding laser emitters 15 are fixedly mounted on the chip removal bottom box 1; The laser emitted by the laser emitter 15 will irradiate the center position of the laser receiving plate 12. It can be judged whether the conveying box 10 has positional displacement based on the laser irradiation position on the laser receiving plate 12. If positional displacement occurs, the laser irradiation position on the laser receiving plate 12 will not be in the center position. When positional displacement is detected, the displacement distance amplitude of the conveying box 10 can be directly monitored based on the offset distance of the laser irradiation position.

[0033] The adjustment assembly includes a servo motor 11 fixedly mounted in the chip removal bottom box 1, a driving roller 17 fixedly mounted on the driving end of the servo motor 11, a threaded adjustment rod 18 fixedly mounted on the driving roller 17, a limit nut 19 fixedly mounted on the linkage plate 16, and the limit nut 19 is threadedly connected to the threaded adjustment rod 18; If it is determined that the conveying box 10 is offset, the servo motor 11 can be started according to the offset distance, and the servo motor 11 drives the driving roller 17 to rotate forward and reverse. The rotation of the driving roller 17 drives the threaded adjustment rod 18 to rotate, and then drives the limiting nut 19 threadedly connected thereto to move horizontally. Since the limiting nut 19 is set on the linkage plate 16, when the limiting nut 19 moves, it will synchronously drive the linkage plate 16 to move, and then drive the conveying box 10 to adjust the overall position through multiple sliding rods 14; The servo motor 11 can be used to control the rotation direction of the driving roller 17 to control the movement direction of the limit nut 19 and the linkage plate 16, so as to realize the left and right position adjustment of the conveying box 10. At the same time, the movement distance of the linkage plate 16 can be controlled by controlling the number of rotations of the driving roller 17, thereby realizing the adjustment of the movement distance of the conveying box 10. The deviation direction and deviation distance of the conveying box 10 can be judged in real time according to the laser irradiation position on the laser receiving plate 12, and the direction can be adjusted by the servo motor 11 to move the conveying box 10 and complete the reference correction, so that the laser emitted by the laser emitter 15 on the adjusted conveying box 10 can be directly irradiated to the center position of the laser receiving plate 12, thereby completing the correction of the conveying box 10 and completing the external correction of the chip removal guide rail.

[0034] Example 4: Reference Figure 1-Figure 3 as well as Figures 9-15 The difference between this embodiment and the third embodiment is that: a deflection detection component and a correction component are provided in the internal adjustment unit, wherein the deflection detection component is provided with a laminating frame 24 for detecting the deviation of the conveying guide rail 8; The deflection measuring assembly includes two laminating frames 24 slidably mounted in the conveying box 10 , and the two laminating frames 24 are respectively fitted with the upper and lower sides of the conveying guide rail 8 ; The two laminating racks 24 are respectively located at the upper and lower edges of the conveying guide rail 8, and are respectively flush with the two sides of the conveying guide rail 8, that is, the conveying guide rail 8 is located in the middle of the two laminating racks 24. At this time, if the conveying guide rail 8 is deviated to the left or right, it will synchronously drive the two laminating racks 24 to shift synchronously, thereby realizing real-time synchronous monitoring of the position of the conveying guide rail 8.

[0035] Two correction boxes 21 are fixedly installed in the conveying box 10, and a transmission mechanism is installed between the two laminating frames 24 and the correction boxes 21 on both sides. The correction boxes 21 are filled with hydraulic oil. The transmission mechanism includes two trigger tubes 26 fixedly connected to the calibration box 21. The ends of the two trigger tubes 26 are slidably mounted with piston members 28. The ends of the two piston members 28 are fixedly mounted on the corresponding fitting frames 24. A sliding plate 30 is slidably mounted in the calibration box 21. If the conveying guide rail 8 is offset, it will drive the laminating frame 24 to move synchronously. When the laminating frame 24 moves, it will squeeze the piston member 28 on its side, causing the piston member 28 to move in the trigger tube 26. When the piston member 28 moves, it will squeeze the hydraulic oil in the trigger tube 26, causing the hydraulic oil to be pressed into the correction box 21. At this time, when the hydraulic oil in the correction box 21 increases, it will push the sliding plate 30 to move. The displacement distance of the conveying guide rail 8 can be indirectly judged by the moving distance of the sliding plate 30, thereby realizing the quantitative judgment of the displacement of the conveying guide rail 8.

[0036] In a further embodiment, the correction assembly cooperates with the laminating frame 24 to achieve the correction of the conveyor guide rail 8. The correction assembly includes a middle support plate 32 fixedly installed in the correction box 21, a second sliding plate 31 is slidably installed in the correction box 21, and a return mechanism is installed between the middle support plate 32 and the sliding plate 1 30 and the sliding plate 2 31; The return mechanism includes a hydraulic push rod 33 fixedly mounted on the middle support plate 32, a push rack 34 fixedly mounted on the driving end of the hydraulic push rod 33, and an extrusion spring 35 fixedly mounted between the push rack 34 and the second sliding plate 31, a trigger rod 36 fixedly mounted on the second sliding plate 31, and a trigger button 37 fixedly mounted on the push rack 34 to cooperate with the trigger rod 36; Attached to the instruction manual Figure 14It can be seen that when the sliding plate 30 moves to the left, it will drive the trigger rod 36 on it to move. When the trigger rod 36 moves to the squeezing trigger button 37, the trigger button 37 will be triggered. At this time, the hydraulic push rod 33 on the left side of the middle support plate 32 will be started, thereby pushing the pushing rack 34 on the left to move. When the left pushing rack 34 moves, it will drive the sliding plate 30 to move right and reset through the squeezing spring 35, thereby squeezing the hydraulic oil in the correction box 21 back into the trigger tube 26, and then pushing the piston member 28 to return, thereby pushing the conveying guide rail 8 to reset, and through the control of the hydraulic push rod 33, the rightward movement distance of the sliding plate 30 is made the same as the leftward movement distance of the front, so that the conveying guide rail 8 can return to the initial middle position, thereby realizing automatic correction of the end position of the conveying guide rail 8.

[0037] Two conducting tubes 25 are fixedly connected to the correction box 21. Multiple correction blocks 22 are provided in the conveying box 10 via multiple sets of support springs 27. Each correction block 22 is slidably fitted with the side of the conveying guide rail 8. Multiple correction tubes are fixedly connected to each conducting tube 25, and a piston 29 is slidably installed between each correction tube and the corresponding correction block 22. When calibrating the end of the conveying guide rail 8, the right hydraulic push rod 33 is simultaneously activated, pushing the second sliding plate 31 to the right by the same distance through the right pushing frame 34 until the right trigger button 37 contacts the right trigger rod 36, causing the second sliding plate 31 to press out the same amount of hydraulic oil into the two transmission pipes 25, completing the automatic extrusion of the hydraulic oil in the calibration box 21; When the hydraulic oil in the transmission tube 25 increases, it will enter the multiple correction tubes and push the corresponding piston member 29 to move. When the piston member 29 moves, it pushes the correction block 22 to move the correction block 22 to the initial reference correction position. When the correction block 22 moves, it pushes the middle conveyor guide rail 8 to move, causing the middle conveyor guide rail 8 to move back to the center position, thereby achieving multi-point automatic correction of the middle position of the conveyor guide rail 8. That is, by combining end correction with middle multi-point automatic correction, the rapid reference correction of the conveying guide rail 8 can be automatically completed, so that the conveying guide rail 8 always remains in the center line position, which can effectively avoid the situation where the ends of the conveying guide rail 8 are aligned but the middle is deviated, making the position of the conveying guide rail 8 more accurate.

[0038] The specific working principle of this reference calibration device is: When performing reference calibration, the laser emitter 15 is started to emit a horizontal laser. The laser emitted by the laser emitter 15 will irradiate the center position of the laser receiving plate 12. It can be determined whether the conveyor box 10 has positional deviation based on the laser irradiation position on the laser receiving plate 12. If positional deviation occurs, the laser irradiation position on the laser receiving plate 12 will not be at the center position. When positional deviation is detected, the deviation distance amplitude of the conveyor box 10 can be directly monitored based on the offset distance of the laser irradiation position. If it is determined that the conveying box 10 is offset, the servo motor 11 can be started according to the offset distance, and the servo motor 11 drives the driving roller 17 to rotate forward and reverse. The rotation of the driving roller 17 drives the threaded adjustment rod 18 to rotate, and then drives the limiting nut 19 threadedly connected thereto to move horizontally. Since the limiting nut 19 is set on the linkage plate 16, when the limiting nut 19 moves, it will synchronously drive the linkage plate 16 to move, and then drive the conveying box 10 to adjust the overall position through multiple sliding rods 14; The deviation direction and deviation distance of the conveying box 10 are judged in real time according to the laser irradiation position on the laser receiving plate 12, and the direction is adjusted by the servo motor 11 to move the conveying box 10 and complete the reference correction, so that the laser emitted by the laser emitter 15 on the adjusted conveying box 10 can directly irradiate the center position of the laser receiving plate 12, thereby completing the correction of the conveying box 10 and completing the external correction of the chip removal guide rail.

[0039] When the conveying guide rail 8 deviates from its position, it drives the laminating frame 24 to move synchronously. When the laminating frame 24 moves, it squeezes the piston member 1 28 on its side to move in the trigger tube 26. When the piston member 1 28 moves, it squeezes the hydraulic oil in the trigger tube 26 and presses it into the correction box 21. The increase in hydraulic oil in the correction box 21 pushes the sliding plate 1 30 to move. The displacement distance of the sliding plate 1 30 can be used to indirectly determine the displacement distance of the conveying guide rail 8, thereby achieving quantitative determination of the displacement of the conveying guide rail 8. The left movement of the sliding plate 30 will drive the trigger rod 36 to move, and the trigger rod 36 moves to the squeezing trigger button 37 to trigger it. The hydraulic push rod 33 on the left side of the middle support plate 32 is started, pushing the left push rack 34 to move. The movement of the left push rack 34 drives the sliding plate 30 to move right and reset through the squeezing spring 35, squeezing the hydraulic oil in the correction box 21 back into the trigger tube 26, pushing the piston member 28 back to its position, pushing the conveying guide rail 8 to reset, and realizing automatic correction of the end position of the conveying guide rail 8.

[0040] When calibrating the end of the conveying guide rail 8, the right hydraulic push rod 33 is simultaneously activated, pushing the second sliding plate 31 to the right by the same distance through the right pushing frame 34 until the right trigger button 37 contacts the right trigger rod 36, causing the second sliding plate 31 to press out the same amount of hydraulic oil into the two transmission pipes 25, completing the automatic extrusion of the hydraulic oil in the calibration box 21; The increased hydraulic oil in the transmission tube 25 will enter the multiple correction tubes and push the corresponding piston member 29 to move. When the piston member 29 moves, it will push the correction block 22 to move, so that the correction block 22 moves to the initial reference correction position. When the correction block 22 moves, it will push the middle conveying guide rail 8 to move, so that the middle conveying guide rail 8 moves back to the center position, thereby realizing automatic correction of the middle position of the conveying guide rail 8.
