Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
In the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
The gear and the rack are in meshing transmission, and when force is transmitted in the forward direction, the tooth profile of one side of the gear tooth of the gear is abutted against the tooth profile of the gear tooth adjacent to the gear tooth in the forward direction of the rack, so that the force is transmitted; however, when the force is transmitted reversely, a gap is formed between the tooth profile of the other side of the gear tooth of the gear and the tooth profile of the gear tooth adjacent to the rack in the reverse direction, and the gap is a tooth gap.
The application provides a gear transmission processingequipment 100 through set up first gear drive 21 and second gear drive 31 that output torque resists on rack 10 to avoid the gear on the rack 10 to form the backlash at the antiport in-process, and then improve the gear transmission precision.
Referring to fig. 1, 2 and 7, a gear-driven machining device 100 provided in an embodiment of the present application is configured to be disposed on a working platform 200 of a machine tool and slidably connected to the working platform 200, and includes at least two racks 10, a plurality of first driving mechanisms 20, and a plurality of second driving mechanisms 30.
Each rack 10 extends along the X-axis direction, and each rack 10 is disposed on the working platform 200 at intervals. It is understood that the rack 10 is fixedly installed on the working platform 200, the number of the racks 10 is two or more, and the rack 10 is engaged with each driving mechanism to move the gear-driven machining device 100 relative to the working platform 200. Here, the rack 10 is extended in the X-axis direction, which is only for illustration, and here, the X-axis direction may be any horizontal direction parallel to the plane of the working platform 200. Meanwhile, the racks 10 are arranged in parallel to facilitate the concentrated transmission of force.
The first driving mechanism 20 includes a first gear transmission mechanism 21, and the first gear transmission mechanism 21 is engaged and connected with any one or more racks 10. It will be appreciated that the first drive mechanism 20 is used to provide the power required for the geared machining device 100 to slide on the work platform 200. The first gear transmission mechanism 21 is used for transmitting the driving force to the rack 10 to realize the output of the driving force. The number of the first driving mechanisms 20 is not limited, and may be one, or may be plural, and the number of the first gear transmission mechanisms 21 may be one or plural. When the number of the first gear transmission mechanisms 21 is one, the first gear transmission mechanisms are meshed with one rack 10; when there are a plurality of first gear transmission mechanisms 21, they may be selectively engaged with one rack 10, or may be engaged with a plurality of racks 10.
When there are a plurality of first driving mechanisms 20, the directions in which the gear-driven machining device 100 slides on the work platform 200 by the first driving mechanisms 20 should be the same, that is, the directions of the power supplied to the gear-driven machining device 100 by the first driving mechanisms 20 are the same in the X-axis direction; that is, the direction in which each of the first drive mechanisms 20 supplies power to the gear transmission machining device 100 is the same, i.e., each of the first drive mechanisms 20 supplies power to the gear transmission machining device 100 in the positive X-axis direction, or each of the first drive mechanisms 20 supplies power to the gear transmission machining device 100 in the negative X-axis direction.
The second driving mechanism 30 includes a second gear transmission mechanism 31, and the second gear transmission mechanism 31 is engaged and connected with any one or more racks 10. Similarly, the second drive mechanism 30 has the same function as the first drive mechanism 20, and the second gear transmission mechanism 31 has the same function as the first gear transmission mechanism 21, and specifically, reference may be made to the first drive mechanism 20 and the first gear transmission mechanism 21.
In summary, the first gear transmission 21 and the second gear transmission 31 may be engaged with one or more racks 10. Thus, there is a first gear transmission 21 and a second gear transmission 31 in meshing connection with the same rack 10, and there is a first gear transmission 21 and a second gear transmission 31 in meshing connection with different racks 10. Regardless of the arrangement of the gear mechanisms, the output torque of each first gear mechanism 21 is resisted by the output torque of each second gear mechanism 31, that is, if each first gear mechanism 21 rotates relative to the rack 10 to move the gear-driven machining device 100 in the positive X-axis direction, each second gear mechanism 31 hinders the gear-driven machining device 100 from moving in the positive X-axis direction to hinder the rotation of the first gear mechanism 21, and similarly, if each first gear mechanism 21 rotates relative to the rack 10 to move the gear-driven machining device 100 in the negative X-axis direction, each second gear mechanism 31 hinders the gear-driven machining device 100 from moving in the negative X-axis direction to hinder the rotation of the first gear mechanism 21. Thus, when each first gear transmission mechanism 21 rotates reversely or each second gear transmission mechanism 31 rotates reversely, a supporting force is obtained, and the backlash phenomenon is avoided.
Illustratively, the first gear transmission mechanism 21 and the second gear transmission mechanism 31 which are in meshed connection with the same rack 10 rotate in opposite directions. It can be understood that, taking the first gear transmission mechanism 21 rotating in the positive direction and the second gear transmission mechanism 31 rotating in the negative direction as an example, when the two mechanisms rotate in the opposite directions simultaneously, a reverse supporting effect is formed on the corresponding gear transmission, so as to eliminate the backlash problem caused by the first gear transmission mechanism 21 rotating in the negative direction or the second gear transmission mechanism 31 rotating in the positive direction.
Illustratively, the rotation directions of the first gear transmission mechanism 21 and the second gear transmission mechanism 31 engaged with different racks 10 need to be selected and judged. When the tooth structures of any two or more racks 10 are arranged towards or away from each other, then the rotation directions of the first gear transmission mechanism 21 and the second gear transmission mechanism 31 are the same; in this case, taking the first gear transmission mechanism 21 rotating in the forward direction and the second gear transmission mechanism 31 rotating in the forward direction as an example, when both rotate in the same direction, the two mechanisms will form a reverse supporting function for the corresponding gear transmission to eliminate the backlash problem caused by the first gear transmission mechanism 21 rotating in the reverse direction or the second gear transmission mechanism 31 rotating in the reverse direction. When the tooth structure of each rack 10 is disposed toward the same side, the rotation directions of the first gear transmission mechanism 21 and the second gear transmission mechanism 31 are opposite. Taking the first gear transmission mechanism 21 rotating in the positive direction and the second gear transmission mechanism 31 rotating in the negative direction as an example, when the first gear transmission mechanism 21 and the second gear transmission mechanism 31 rotate in the opposite directions at the same time, the two mechanisms can form a reverse supporting function for the corresponding gear transmission, so as to eliminate the problem of backlash caused by the first gear transmission mechanism 21 rotating in the negative direction or the second gear transmission mechanism 31 rotating in the positive direction.
The utility model provides a gear drive processingequipment 100 has two degrees of freedom of movement in the X axle direction, along the degree of freedom of movement in X axle positive direction and along the degree of freedom of movement in the X axle negative direction promptly. Specifically, the first gear transmission mechanism 21 of each first driving mechanism 20 is engaged with the corresponding rack 10 to move the gear-driven machining device 100 in the positive X-axis direction, and the second gear transmission mechanism 31 of each second driving mechanism 30 is engaged with the corresponding rack 10 to move the gear-driven machining device 100 in the negative X-axis direction; alternatively, the first gear transmission mechanism 21 of each first driving mechanism 20 is engaged with the corresponding rack 10 to move the gear-driven machining device 100 in the reverse direction of the X-axis, and the second gear transmission mechanism 31 of each second driving mechanism 30 is engaged with the corresponding rack 10 to move the gear-driven machining device 100 in the positive direction of the X-axis. Here, the output torque of each first gear transmission mechanism 21 is resisted with the output torque of each second gear transmission mechanism 31, so that each first gear transmission mechanism 21 obtains a supporting force when rotating in the reverse direction or each second gear transmission mechanism 31 obtains a supporting force when rotating in the reverse direction, and thus, the corresponding first gear transmission mechanism 21 and the corresponding second gear transmission mechanism 31 are subjected to a reverse supporting action, and backlash is prevented from being formed. As described above, the gear transmission machining device 100 can be stably moved regardless of whether it is moved in the positive direction or the negative direction of the X-axis direction, and the conveyance accuracy can be ensured.
Referring to fig. 2 to 5, in an embodiment, the first gear transmission mechanism 21 includes a plurality of first sub-gears 211 in meshing transmission, wherein one of the first sub-gears 211 is in meshing connection with the rack 10, and the second gear transmission mechanism 31 includes a plurality of second sub-gears 311 in meshing transmission, wherein one of the second sub-gears 311 is in meshing connection with the rack 10. It will be appreciated that the number of first and second sub-gears 211, 311 may be adjusted depending on the actual gear ratio. For example, when the first gear transmission mechanism 21 includes one first sub-gear 211, the first driving mechanism 20 drives the first sub-gear 211 to mesh with the corresponding rack 10, and when the first gear transmission mechanism 21 includes a plurality of first sub-gears 211, one of the first sub-gears 211 is meshed with the corresponding rack 10. Likewise, the number of the second sub-gears 311 of the second gear transmission 31 can also be adjusted in this way.
For example, the number of the first sub gears 211 and the number of the second sub gears 311 may be the same, and the output gear ratio of the gear transmission mechanism composed of the sub gears is the same. Alternatively, the number of the first sub-gears 211 is different from the number of the second sub-gears 311, and the output gear ratios of the gear transmission mechanisms composed of the sub-gears are the same. Alternatively, the number of the first sub-gears 211 and the number of the second sub-gears 311 are different, and the output gear ratio of the gear transmission mechanism composed of the sub-gears is also different.
Wherein, the rotation directions of the first sub gear 211 and the second sub gear 311 which are engaged with the rack 10 with the same tooth structure orientation are opposite.
When the first sub gear 211 and the second sub gear 311 are engaged with the same rack 10, since the rack 10 engaged with the first sub gear 211 and the second sub gear 311 is the same rack 10, it is obvious that the tooth structure of the rack 10 faces the same direction and the rotation directions of the first sub gear 211 and the second sub gear 311 are opposite. It can be understood that, taking the first sub-gear 211 rotating in the forward direction and the second sub-gear 311 rotating in the reverse direction as an example, when the first sub-gear 211 and the second sub-gear 311 rotate in the reverse direction at the same time, the transmission of the two sub-gears will form a reverse supporting function, so as to eliminate the backlash problem caused by the rotation of the first sub-gear 211 in the reverse direction or the rotation of the second sub-gear 311 in the forward direction.
When the first sub gear 211 and the second sub gear 311 are engaged with different racks 10, when the tooth structures of the respective racks 10 are disposed toward the same side, that is, when the tooth structures of the racks 10 are disposed toward the same side, the rotation directions of the first sub gear 211 and the second sub gear 311 are opposite to each other. Taking the first sub-gear 211 rotating in the forward direction and the second sub-gear 311 rotating in the reverse direction as an example, when the first sub-gear 211 and the second sub-gear 311 rotate in the reverse direction at the same time, the two gears will form a reverse supporting function for the corresponding gear transmission, so as to eliminate the backlash problem caused by the rotation of the first sub-gear 211 in the reverse direction or the rotation of the second sub-gear 311 in the forward direction.
Wherein, the rotation directions of the first sub gear 211 and the second sub gear 311 engaged with the rack 10 with the opposite tooth structures are the same.
When the tooth structures of any two or more racks 10 are disposed toward or away from each other, i.e., when the tooth structures of the racks 10 are disposed toward each other, the rotation directions of the first and second sub-gears 211 and 311 are the same. In this case, taking the first sub-gear 211 rotating in the forward direction and the second sub-gear 311 also rotating in the forward direction as an example, when both rotate in the same direction, the two gears will form a reverse supporting function to the corresponding gear transmission, so as to eliminate the backlash problem caused by the first sub-gear 211 rotating in the reverse direction or the second sub-gear 311 rotating in the reverse direction.
Referring to fig. 1 and 6, in one embodiment, the first driving mechanism 20 further includes a first driving motor 22, and an output end of the first driving motor 22 is connected to one of the first sub-gears 211. As can be appreciated, the first driving motor 22 is configured to provide the power required for the rotation of each of the first sub gears 211. When the number of the first sub-gears 211 is one, the first driving motor 22 drives the first sub-gears 211, or when the number of the first sub-gears 211 is multiple, the first driving motor 22 drives one of the first sub-gears 211, and the first sub-gear 211 may be a first sub-gear 211, or may be any intermediate first sub-gear 211. Here, among a set of the plurality of first sub-gears 211 engaged with each other, the first sub-gear 211 engaged with the rack 10 is a last sub-gear 211, the first sub-gear 211 farthest from the rack 10 is a first sub-gear 211, and between them, a middle sub-gear 211 is provided.
The second driving mechanism 30 further includes a second driving motor 32, and an output end of the second driving motor 32 is connected to one of the second sub-gears 311. Similarly, the second driving motor 32 is used to provide the power required by the rotation of each second sub-gear 311. When the number of the second sub-gears 311 is one, the second driving motor 32 drives the second sub-gear 311, or when the number of the second sub-gears 311 is multiple, the second driving motor 32 drives one of the second sub-gears 311, and the second sub-gear 311 may be a first sub-gear 311, or may be an arbitrary middle sub-gear 311.
In one embodiment, when the sum of the driving forces of the first driving motors 22 is not equal to the sum of the driving forces of the second driving motors 32, the geared processing device 100 moves on the working platform 200 along the X-axis.
It is understood that the sum of the driving forces of the first driving motors 22 is the first torque output by the transmission of each first sub gear 211 with the corresponding rack 10, and the sum of the driving forces of the second driving motors 32 is the second torque output by the transmission of each second sub gear 311 with the corresponding rack 10. When the first and second torques are equal, the geared machining device 100 remains relatively stationary with respect to the work platform 200, and once the balance is broken, the geared machining device 100 moves on the work platform 200.
Referring to fig. 2, in one embodiment, the number of the racks 10 is two, and the tooth structures of the two racks 10 are arranged away from each other. It is understood that, in the present embodiment, the two racks 10 can be disposed close to each other, and therefore, the first gear transmission mechanism 21 and the second gear transmission mechanism 31 are arranged in the orientation in which the tooth structures of the racks 10 face outward, that is, there is enough space for the arrangement of the first gear transmission mechanism 21 and the second gear transmission mechanism 31, and therefore, the gear transmission mechanism can be formed of a plurality of sub-gears, and thus can be applied to the case of a high transmission ratio. Of course, the arrangement positions of the two racks 10 may also be arranged at intervals without being close to each other, and only the arrangement of the tooth structures of the two racks 10 deviating from each other is maintained, so as to mainly adapt to the actual arrangement condition of the working platform 200.
Alternatively, referring to fig. 3 and 4, in another embodiment, the tooth structures of the two racks 10 are disposed facing each other. It can be understood that the two racks 10 are disposed at an interval, and the space between the two racks is used for arranging the first gear transmission mechanism 21 and the second gear transmission mechanism 31, and because the space needs to accommodate the first gear transmission mechanism 21 and the second gear rotation mechanism at the same time, the gear transmission mechanism can be composed of a plurality of sub-gears, but the number of the sub-gears is small, so as to be suitable for the situation that the transmission is small.
Alternatively, referring to fig. 5, in other embodiments, the tooth structures of the two racks 10 are disposed toward the same side. It will be appreciated that the two racks 10 are spaced apart and the first gear 21 and the second gear 31 are disposed on the same side of the rack 10, and that there is also sufficient space to accommodate the first gear 21 and the second gear, so that the gear is composed of a plurality of sub-gears for high transmission ratios.
Referring to fig. 2 to 5, in one embodiment, the number of the first sub-gear 211 and the second sub-gear 311 is one, the first sub-gear 211 is engaged with one of the racks 10, and the second sub-gear 311 is engaged with the other rack 10.
Illustratively, the number of the racks 10 is two, when the tooth structures of the two racks 10 are disposed facing each other, the first sub gear 211 and the second sub gear 311 are disposed between the two racks 10, and the first sub gear 211 and the second sub gear 311 may be disposed opposite to each other or may be disposed in a staggered manner.
Illustratively, the number of the racks 10 is two, when the tooth structures of the two racks 10 are arranged away from each other, the first sub-gear 211 and the second sub-gear 311 are respectively arranged on two opposite sides of the two racks 10, and the first sub-gear 211 and the second sub-gear 311 may be arranged opposite to each other or may be arranged in a staggered manner.
For example, the number of the racks 10 is two, when the tooth structures of the two racks 10 are disposed toward the same side, the first sub gear 211 and the second sub gear 311 are disposed on the same side of the two racks 10, respectively, and the first sub gear 211 and the second sub gear 311 may be disposed opposite to each other or may be disposed in a staggered manner.
Referring to fig. 1 and 6, in an embodiment, the gear-driven machining device 100 further includes a first support frame 40 and a machining assembly 50 disposed on the first support frame 40, the first driving mechanism 20 and the second driving mechanism 30 are both disposed on the first support frame 40, and the first support frame 40 is slidably connected to the work platform 200 through the first driving mechanism 20 and the second driving mechanism 30. It is to be appreciated that the first support 40 acts as a carrier for the tooling assembly 50, the first drive mechanism 20 and the second drive mechanism 30. The machining assembly 50 is a device for machining a workpiece. For example, the machining assembly 50 may be a milling assembly, a turning assembly 50, or the like.
Referring to fig. 1 and 6, in one embodiment, the processing assembly 50 includes a second support frame 51 slidably connected to the first support frame 40 along the Y-axis direction, and a first lead screw assembly 52 disposed on the first support frame 40 and used for driving the second support frame 51 to slide relative to the first support frame 40.
