Description

Technical Field

[0001] This invention relates to the technical field of machine tool guideways, and more specifically to an auxiliary device for rolling guideways of machine tools. Background Technology

[0002] Guide rails are crucial linear guiding components in machine tools, affecting their rigidity, operational accuracy, and accuracy retention. Currently, the most commonly used guide rails are rolling guides and sliding guides, each with its own advantages and disadvantages. Sliding guides offer high load-bearing capacity, good shock absorption, and excellent guiding accuracy. However, sliding guides are difficult to manufacture, requiring manual scraping. They also have a high coefficient of friction, resulting in greater running resistance and low-speed creep. Over time, they are prone to wear, affecting operational accuracy.

[0003] Therefore, more and more guide rails are now adopting rolling guide rails. Rolling linear guide rails use rollers or cylinders to roll infinitely on the guide rail, which can make the worktable move in a straight line along the guide rail. Rolling guide rails have the characteristics of high load capacity, high precision, low friction coefficient, and high speed with low wear. However, they have low damping and poor shock absorption. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a rolling guide auxiliary device for machine tools. This auxiliary device allows the guide to simultaneously possess the characteristics of both sliding and rolling guides, giving it the advantages of rolling guides such as high precision, high speed, low friction, and low wear, as well as the high load-bearing capacity, high damping and shock absorption characteristics, and high-precision positioning of sliding guides.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rolling guideway auxiliary device for a machine tool includes a worktable and a guideway. The worktable is movably connected to the guideway via a rolling assembly. The device also includes several sets of supporting auxiliary devices. The bottom of the worktable has a receiving groove, and the supporting auxiliary devices are disposed within the receiving groove. Each supporting auxiliary device includes a floating component, a pressing component, a buffer component, and a flexible strip. The pressing component presses against the buffer component, and the buffer component presses against the floating component. The bottom portion of the floating component is exposed outside the receiving groove. The flexible strip is located at the bottom of the floating component and is in contact with the guideway. The floating component can move within the receiving groove to ensure that the flexible strip is tightly attached to the guideway.

[0007] Furthermore, a fixed seat is provided at one end of the receiving groove near the groove opening, the buffer component includes a butterfly spring, the floating component includes a floating bushing, the floating bushing is movably connected to the fixed seat, one end of the butterfly spring is connected to the floating bushing, and the other end is connected to the top pressing component, and the surface of the floating bushing is provided with a limiting shaft for limiting the displacement of the floating bushing in the fixed seat.

[0008] Furthermore, the fixed seat has a stepped surface, which divides the fixed seat into a floating cavity and a compression cavity that are interconnected. The floating bushing is located in the floating cavity. The buffer also includes a compression spring. The top pressing component includes a pressure plate, a guide shaft, a limiting nut, and a stop plate. The pressure plate presses against the guide shaft. The guide shaft extends through the stop plate into the floating bushing. The compression spring and the butterfly spring are both sleeved on the guide shaft in the compression cavity. One end of the compression spring is connected to the stepped surface, and the other end is connected to the stop plate. The limiting nut is connected to the guide shaft outside the compression cavity and presses against the stop plate.

[0009] Furthermore, the bottom of the pressure plate is provided with a pressure head, and the top pressure component also includes a steel ball, which is located between the pressure head and the guide shaft.

[0010] Furthermore, the rolling assembly includes a slider, and the slider is provided with a shifting component. The surface in contact between the guide rail and the roller of the rolling assembly is defined as the bearing surface, and the direction in which the roller of the rolling assembly rolls on the bearing surface is defined as the movement direction. The shifting component is used to shift the roller of the rolling assembly in a direction perpendicular to the movement direction, so that the pressing end of the roller of the rolling assembly that is pressed during the movement is shifted to contact the tooling table or the bearing surface.

[0011] Furthermore, the bottom of the slider is provided with at least one set of roller grooves, which are arranged along the direction of movement. Each roller groove contains multiple rollers. When the slider is connected to the guide rail, the rollers are partially exposed outside the roller grooves and in contact with the bearing surface of the guide rail. The opening of the roller grooves is provided with a constriction to prevent the rollers from completely disengaging from the roller grooves.

[0012] Furthermore, the shifting assembly includes a shifting belt and a shifting power component. The shifting belt passes horizontally through the groove and is located on the inner top surface of the groove. When the slider is connected to the guide rail, the roller presses against the shifting belt. The shifting power component is used to drive the shifting belt to move, so that the shifting belt drives the roller to rotate in a direction perpendicular to the direction of movement.

[0013] Furthermore, the transposition belt includes several sets of transposition sub-belts, each set of transposition sub-belts is arranged in parallel, and there is a separation distance between each set of transposition sub-belts. Each set of transposition sub-belts passes horizontally through the rolling groove corresponding to a roller. The transposition power component drives each set of transposition sub-belts to move synchronously, so as to drive the corresponding roller to rotate and change position.

[0014] Furthermore, the two ends of the roller groove respectively penetrate the side wall of the slider to form replacement ports, each of the replacement ports is provided with a detachable sealing plate, and any one of the replacement ports is provided with a connecting buckle for connecting the slide plate.

[0015] Furthermore, the inner wall of the chute is provided with several detection points corresponding to the rollers, and each detection point is provided with a pressure sensor.

[0016] The beneficial effects of this invention are as follows: The linear guide is used for linear operation, and multiple support auxiliary devices are arranged on the tooling table to make the guide rail have the characteristics of both sliding and rolling guide rails. It has the advantages of rolling guide rails such as high precision, high speed, low friction, and low wear, as well as the advantages of sliding guide rails such as high load-bearing capacity, high damping and shock absorption characteristics, and high-precision positioning.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Since more and more guideways 101 are now using rolling guideways 101, and rolling linear guideways 101 achieve linear motion of the worktable along the guideway 101 by infinitely rolling rollers or rollers on the guideway 101, rolling guideways 101 have the characteristics of high load-bearing capacity, high precision, low friction coefficient, and high speed with low wear. However, they have low damping and poor shock absorption capacity. Therefore, this invention designs an auxiliary device for the rolling guideway 101 of such machine tools, such as... Figure 1 As shown, the fixture includes a worktable and a guide rail 101. The tooling table 15 is movably connected to the guide rail 101 via a rolling assembly. It also includes several sets of support auxiliary devices 107, which are arranged at corresponding points according to actual needs. Typically, two support auxiliary devices 107 on the same guide rail 101 are evenly spaced. Figure 2 As shown, taking any one of the support auxiliary devices 107 as an example, a receiving groove is provided at the bottom of the tooling table 15, and the support auxiliary device 107 is set in the receiving groove. The support auxiliary device 107 includes, from top to bottom, a pressing member, a buffer member, a floating member, and a soft belt 8 (PTEF soft belt 8). The pressing member is located at the top of the receiving groove and presses against the buffer member. The buffer member presses against the floating member. The bottom part of the floating member is exposed outside the receiving groove. The bottom of the floating member exposed outside the receiving groove is also provided with a connecting plate 7 made of Babbitt alloy ZchSnSb11-6. The soft belt 8 is located on the bottom surface of the connecting plate 7. In the initial state, the pressing member applies downward pressure to compress the buffer member, and the buffer member applies pressure to the floating member. The soft strip 8 at the bottom of the moving part is in contact with the guide rail 101. When the tooling table 15 slides, if there is up-and-down shaking, the soft strip 8 will be pushed upward. At this time, the floating part can move in the receiving groove so that the soft strip 8 is close to the guide rail 101. When the tooling table 15 moves on the guide rail 101, the soft strip 8 can absorb the vibration generated during the movement. That is, the present invention uses a rolling linear guide rail 101 for linear operation. Multiple support auxiliary devices are arranged on the tooling table 15 so that the guide rail 101 can have the characteristics of both the sliding guide rail 101 and the rolling guide rail 101. It has the advantages of the rolling guide rail 101 such as high precision, high speed, low friction, and low wear, and also has the advantages of the sliding guide rail 101 such as high load-bearing capacity, high damping shock absorption characteristics, and high-precision positioning.

[0024] like Figure 2As shown, a fixed seat 9 is provided at one end of the receiving groove near the groove opening. The fixed seat 9 is embedded in the receiving groove and is externally fixed to the bottom surface of the tooling table 15 by bolts. The buffer component includes a butterfly spring 5, and the floating component includes a floating bushing 10. The floating bushing 10 is movably connected to the fixed seat 9. One end of the butterfly spring 5 is connected to the floating bushing 10, and the other end is connected to the top pressure component. The surface of the floating bushing 10 exposed outside the receiving groove is provided with a limiting shaft 6 to limit the displacement of the floating bushing 10 in the fixed seat 9, so as to avoid excessive displacement of the floating bushing 10, which would cause excessive compression or tension of the butterfly spring 5 and damage the butterfly spring 5. Furthermore, the fixed seat 9 is provided with a stepped surface, which divides the fixed seat 9 into interconnected floating cavities and pressure cavities. The compression chamber is located above the floating chamber, and the floating bushing 10 is located inside the floating chamber. The buffer also includes a compression spring 4. The top pressing component includes a pressure plate 13, a guide shaft 11, a limiting nut 14, and a stop plate 12. A waterproof cover plate 1 is provided above the pressure plate 13 and installed in the receiving groove through a sealing ring 2. The pressure plate 13 presses against the guide shaft 11, and the guide shaft 11 extends through the stop plate 12 into the floating bushing 10. The compression spring 4 and the butterfly spring 5 are both sleeved on the guide shaft 11 inside the compression chamber. The diameter of the compression spring 4 is larger than the diameter of the butterfly spring 5. Therefore, one end of the compression spring 4 is connected to the stepped surface, and the other end is connected to the stop plate 12. The limiting nut 14 is connected to the guide shaft 11 outside the compression chamber and presses against the stop plate 12 to adjust the elastic force of the compression spring 4 and the butterfly spring 5.

[0025] like Figure 2 As shown, the bottom of the pressure plate 13 is provided with a pressure head, and the top pressure component also includes a steel ball 3. The steel ball 3 is located between the pressure head and the guide shaft 11. The steel ball 3 can correct deviation, guide, and make better contact. When the guide rail 101 is not flat, it will swing a little when moving. The steel ball 3 can provide better support.

[0026] Since the rolling components of the rolling guide 101 include two types—one where the rollers of the rolling component roll within the limiting grooves on both sides of the guide 101, and the other where the rollers of the rolling component roll on the upper surface of the guide 101—both types of rollers are subjected to downward pressure from the tooling table 15. During reciprocating rolling, the rollers can only roll within a set linear track, thus causing deformation. This is similar to the rolling bearings on bicycle wheels; after a period of use, the rollers inside the bearing deform and require the support of several other rollers to push them. Therefore, the rolling guide 101 device used on high-precision machine tools has relatively high requirements for the condition of the rollers. Figure 3 and Figure 4As shown, the rolling assembly of the present invention includes a slider 102, and a shifting assembly is provided inside the slider 102. The surface in contact between the guide rail 101 and the roller of the rolling assembly is defined as the bearing surface, that is, the bearing surface is the upper surface of the guide rail 101. The direction in which the roller of the rolling assembly rolls on the bearing surface is defined as the movement direction, that is, the length direction of the guide rail 101. When the roller reciprocates on the guide rail 101, the roller will deform on both sides of the width direction of the guide rail 101. Therefore, the shifting assembly is used to shift the roller of the rolling assembly in a direction perpendicular to the movement direction, so that the pressing end of the roller of the rolling assembly during the movement is shifted to contact the tooling table 15 or the bearing surface. That is, after the roller rolls a certain stroke, the shifting assembly rotates the roller in the width direction of the guide rail 101, so that the deformed end of the roller is used to roll linearly on the guide rail 101, and the rolling surface of the roller is adjusted intermittently to improve the service life of the roller.

[0027] like Figure 4 As shown, the bottom of the slider 102 is provided with at least one set of roller grooves 103. In this invention, the slider 102 is provided with two sets of roller grooves 103. The two sets of roller grooves 103 are parallel to each other and are both arranged along the direction of movement. There are multiple rollers in the roller grooves 103. Assuming that there are 10 rollers in each set of roller grooves 103, each roller is tangent to each other and exactly fills the roller groove 103. When the slider 102 is connected to the guide rail 101, each roller is partially exposed outside the roller groove 103 and the guide rail 101. The bearing surface contacts the roller. When the slider 102 slides, the roller in the groove 103 can roll on the guide rail 101. When the slider 102 is removed from the guide rail 101, in order to prevent the roller from falling out of the groove 103, a constriction 104 is provided at the groove opening of the groove 103 to prevent the roller from completely leaving the groove 103. That is, the inner walls on both sides of the groove opening of the groove 103 are provided with arc-shaped inclined surfaces. The arc-shaped inclined surfaces are adapted to the curved surface of the roller, which can limit the roller from falling out, but does not limit the roller from rotating.

[0028] Since this invention involves rolling a roller on the upper surface of the guide rail 101, in order to limit the rolling stroke of the roller, that is, to ensure that the roller rolls in a straight line on the guide rail 101, one method is as follows: Figure 4 As shown, a slider is provided at the bottom of the slider 102 for sliding in the limiting grooves on both sides of the guide rail 101. Another method is to provide a rolling groove on the bearing surface of the guide rail 101, and the roller part exposed outside the rolling groove 103 rolls in the rolling groove on the bearing surface.

[0029] Furthermore, such as Figure 4As shown, the slider 102 has a space within which the shifting assembly is located. The shifting assembly includes a shifting belt 105 and a shifting power component. The shifting belt 105 horizontally passes through the roller groove 103 and is located on the inner top surface of the roller groove 103. When the slider 102 is connected to the guide rail 101, the rollers press against the shifting belt 105. The shifting power component includes two roller shafts and a power source. The two roller shafts are horizontally located on both sides of the space, i.e., on each side of the two roller grooves 103. The length direction of the roller shafts is the same as the direction of movement. The shifting belt 105 is sleeved on the two roller shafts. The power source drives the roller shafts to rotate, causing the shifting belt 105 to move, thereby moving the shifting belt 105. 5. The roller is driven to rotate in a direction perpendicular to the direction of motion. The contact surface between the shifting belt 105 and the roller is preferably a leather surface. Since the roller is a smooth sphere, the friction between the leather surface and the roller is large, which can drive the roller to be shifted smoothly. However, in order to avoid the belt being squeezed and damaged by the rolling of the roller for a long time, the contact surface of the shifting belt 105 is set as a leather surface section and a smooth surface section, which are alternately set. In the initial stage, the roller is in contact with the smooth surface section. When the roller needs to be shifted, the shifting belt 105 drives to switch to the leather surface contacting the roller. After the leather surface drives the roller to rotate a certain angle, it switches back to the smooth surface contacting the roller.

[0030] To improve the strength of the groove 103, the transposition belt 105 includes several sets of transposition sub-belts. Assuming there are 10 rollers, there are 10 sets of transposition sub-belts. The roller shaft is set accordingly, and the 10 sets of transposition sub-belts are all wound on the same roller shaft. Each set of transposition sub-belts is arranged in parallel, and each set of transposition sub-belts has the same separation distance. Each set of transposition sub-belts passes horizontally through the groove 103 corresponding to one roller. The transposition power component drives each set of transposition sub-belts to move synchronously, so as to drive the corresponding roller to rotate and change position.

[0031] like Figure 4 As shown, the two ends of the groove 103 pass through the side wall of the slider 102 to form replacement ports. The replacement ports are located on both sides of the slider 102 in the direction of movement. Each replacement port is provided with a detachable sealing plate 106. The sealing plate 106 is generally connected to the slider 102 by screws. Each replacement port is provided with a connecting buckle for connecting the slide plate. Since the roller needs to be replaced after a certain period of time, the replacement method is to open the sealing plate 106 of the two replacement buckles, push out the roller inside, and push in a new roller at the same time.

[0032] The replacement rollers can be done in two ways: Method 1 and Method 2. In Method 1, the closing plates 106 of the two replacement ports are opened, and the slide plate is tilted and connected to the replacement port via the connecting buckle. Rollers are placed inside the slide plate. At this time, the slider 102 is slid towards the replacement port on the side without the slide plate. During this process, the rollers in the groove are not obstructed by the closing plates 106 and roll out of the replacement port. Simultaneously, new rollers slide down the slide plate and enter the replacement port. After all 10 rollers in the groove have rolled out, the closing plates 106 are closed to shut off the replacement port on that side. At this time, it is necessary to wait for all 10 rollers in the slide plate to enter the groove before removing the slide plate and closing the replacement port on that side with the closing plates 106.

[0033] Method 2: Similarly, open the closing plate 106 of both replacement ports, push the roller into one replacement port so that the roller in the chute is pushed out from the other replacement port, push out 10 rollers in the chute in sequence, and push in 10 new rollers to replace them. Then close the closing plate 106 to close the replacement port.

[0034] Several detection points corresponding to the rollers are provided on the inner wall of the chute. Each detection point is equipped with a pressure sensor. The machine tool in this invention is an intelligent machine tool, which has a controller and sensors. The controller includes a data acquisition module, a processing module, and a control module. The data acquisition module is used to collect the pressure values ​​from the pressure sensors. Assuming there are 10 rollers and 10 corresponding detection points, there are 10 pressure sensors. When the rollers are deformed under pressure during rolling, both sides of the rollers deform, and the values ​​collected by the pressure sensors will increase sharply. The processing module will judge based on the pressure value. If the pressure value exceeds the threshold, it will determine that the rollers need to be rotated or replaced. After receiving the feedback signal from the processing module, the control module sets up a chamber above the pressure plate 13. High-pressure air is pumped into the chamber to make the pressure plate 13 press down against the steel ball 3. The pressure plate 12 and the guide shaft move downwards, so the compression spring 4 and the butterfly spring 5 are compressed. The floating bushing 10 presses down, so that the soft belt 8 acts on the guide rail 101. At this time, the slider 102 can open the gap between itself and the guide rail 101 as much as possible. The weight originally applied to the slider 102 by the tooling table 15 is distributed by multiple sets of support auxiliary devices, making it more convenient to replace the rollers in the slider 102. For greater intelligence, a storage chamber for rollers can be set in the slider 102, and the closing plate 106 is also opened and closed by pneumatic components. The control module directly pushes out the rollers in the roller groove 103 by pneumatic means, and then pressurizes the storage chamber for rollers so that the rollers enter the roller groove 103.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
