An automated damper assembling apparatus provided by the present invention is described below with reference to fig. 1 to 10.
The embodiment provides an automatic damper assembling device. The automated damper assembly apparatus may generally include a base 100, a robotic arm 300, and a positioning assembly.
The base 100 is provided with a pre-tightening assembly 200 for clamping the damper body 01, and the damper body 01 is provided with a rotatable shaft core 02. The robot arm 300 is provided on the base 100 for holding the gear 03 and mounting the gear 03 to the spindle 02. The positioning assembly is disposed on the base 100, and is used for positioning the shaft core 02 before the gear 03 is mounted, so that the shaft core 02 rotates to a preset mounting angle in the shortest path.
The positioning assembly may generally include two adjustment assemblies 400 and two drive assemblies 500. The two adjusting assemblies 400 are symmetrically arranged with the rotation center of the shaft core 02 as a symmetry center, and the two driving assemblies 500 are respectively connected with the two adjusting assemblies 400. The two adjusting assemblies 400 are configured to gradually approach and clamp the shaft core 02 along the same straight line under the driving of the two driving assemblies 500, wherein the two adjusting assemblies 400 drive the shaft core 02 to rotate to the mounting angle with the shortest path when the shaft core 02 is not at the mounting angle during the process of clamping the shaft core 02. Wherein the mounting angle is preferably set such that the straight wall of the shaft 02 is perpendicular to the driving direction of the driving assembly 500.
As shown in fig. 1, the side wall of the shaft 02 is constituted by two opposite curved walls and two opposite straight walls, and the gear 03 is formed with a through hole adapted to the shape of the side wall of the shaft 02. The base 100 is provided with an upright post 110 which is matched with the shape of the through hole of the gear 03, and a plurality of gears 03 to be assembled are sequentially sleeved on the upright post 110 at a specific angle. It will be appreciated that the position and angle of the gear 03 is fixed relative to the base 100 while the gear 03 is being transferred from the upright 110 to above the hub 02 under the clamping of the robotic arm 300 awaiting assembly.
According to the scheme of the embodiment, the positioning assembly is arranged on the base 100, and before the gear 03 is installed, the shaft core 02 on the damper main body 01 is positioned, so that the shaft core 02 rotates to a preset installation position, the alignment precision of the shaft core 02 and the gear 03 is improved, and the assembly of the shaft core 02 and the gear 03 is ensured to be smooth. The positioning assembly is utilized to enable the shaft core 02 to rotate to a preset installation position in the shortest path, so that the shaft core 02 can be quickly adjusted to the installation position, the assembly efficiency is improved, and the abrasion risk of the shaft core 02, the positioning assembly and other components in the positioning process is reduced.
Further, in the solution of this embodiment, by providing two driving assemblies 500 with the rotation center of the shaft core 02 as the symmetry center, when the two driving assemblies 500 clamp the shaft core 02, a plane formed by two force lines of the shaft core 02 and the driving assemblies 500 passes through the axis of the shaft core 02. When the shaft core 02 rotates under the drive of the adjusting component 400, the stress of the shaft core 02 is more uniform, and the rotation is more stable. The shaft core 02 rotates to a preset installation angle with the shortest path under the drive of the adjusting component 400, so that the time required by angle adjustment of the shaft core 02 is reduced, the assembly efficiency is improved, the abrasion risk of the shaft core 02 is reduced, and the product quality is ensured.
The adjustment assembly 400 may generally include a drive block 410, a first slider 420, and a second slider 430.
The driving block 410 is connected with the driving assembly 500 and approaches the shaft core 02 under the driving of the driving assembly 500. The end surface of the driving block 410 facing the shaft core 02 is a first inclined surface 411. The first slider 420 is slidably disposed on the driving block 410 along the first inclined surface 411. The end surface of the first slider 420 facing the shaft core 02 is a second inclined surface 421. Wherein the first inclined surface 411 and the second inclined surface 421 are opposite in inclination direction. The second slider 430 is slidably disposed on the first slider 420 along the second inclined surface 421. The second slider 430 is configured to slide with respect to the first slider 420 or slide synchronously with the first slider 420, thereby driving the shaft core 02 to rotate to the mounting angle in the shortest path.
When the driving block 410 is driven by the driving assembly 500 to approach the shaft core 02, the first slider 420 and the second slider 430 are driven to approach the shaft core 02 synchronously. After the second slider 430 abuts against the shaft core 02, the driving assembly 500 continuously abuts against the driving block 410 to approach the shaft core 02, so that the second slider 430 slides relative to the first slider 420, or the second slider 430 slides with the first slider 420 relative to the driving block 410. When the second slider 430 moves, the shaft 02 is driven to rotate under the friction effect.
In the solution of this embodiment, the inclination directions of the first inclined surface 411 and the second inclined surface 421 are opposite, so that when the second slider 430 slides relative to the first slider 420 or slides synchronously with the first slider 420, the shaft core 02 can be driven to rotate in two opposite directions, so that the rotation direction of the shaft core 02 is adapted to the deflection direction of the shaft core 02, and therefore, the shaft core 02 can be ensured to rotate to the installation angle in the shortest path, not only the abrasion risk of each component is reduced, but also the positioning time of the shaft core 02 is reduced, and further the assembly efficiency is improved.
In some preferred embodiments, the first slider 420 and the driving block 410, and the second slider 430 and the first slider 420 may be slidably coupled by a dovetail groove.
The adjustment assembly 400 may also generally include a first stop lever 440 and a second stop lever 450.
One end of the first limiting rod 440 passes through the first slider 420, extends from the second slider 430 toward the end face of the shaft core 02, and the other end abuts against the first push rod 441 in the driving block 410. A first spring 442 is provided between the first jack 441 and the driving block 410, and a contact surface between the first stopper rod 440 and the first jack 441 is arranged so as to overlap the first inclined surface 411 when the first stopper rod 440 and the second slider 430 are both abutted against the curved wall of the shaft 02. One end of the second stopper 450 extends from the second slider 430 toward the end face of the shaft 02, and the other end abuts against the second jack 451 of the first slider 420. A second spring 452 is provided between the second jack 451 and the second slider 430, and the contact surface between the second stopper 450 and the second jack 451 is arranged so as to overlap the second inclined surface 421 when the second stopper 450 and the second slider 430 are both abutted against the curved wall of the shaft 02. The first limiting rod 440 is disposed at a side of the first inclined surface 411 away from the shaft core 02, and the second limiting rod 450 is disposed at a side of the second inclined surface 421 away from the shaft core 02. The horizontal interval between the first and second stopper rods 440 and 450 is equal to the interval between the two straight walls of the shaft 02, and the center line between the first and second stopper rods 440 and 450 passes through the rotation center of the shaft 02.
When the shaft core 02 is in different deflection states, after the shaft core 02 abuts against the second slider 430, the first limiting rod 440 and the second limiting rod 450 are in different positions under the abutting pressure of the shaft core 02, so that the sliding states of the first slider 420 and the second slider 430 are different (i.e. after the second slider 430 abuts against the shaft core 02, only the first slider 420 can slide relative to the driving block 410, or only the second slider 430 can slide relative to the first slider 420, or neither the first slider 420 nor the second slider 430 can slide relative to the driving block 410).
As shown in fig. 8, the straight wall of the shaft 02 abuts against the first stopper rod 440, and the curved wall of the shaft 02 abuts against the second stopper rod 450. At this time, the first stopper rod 440 and the first push rod 441 are closer to the shaft core 02 by the first spring 442. The contact surface of the first stop lever 440 and the first push rod 441 is offset from the first inclined surface 411, so that the first slider 420 cannot slide relative to the driving block 410. The contact surface of the second stopper 450 and the second jack 451 coincides with the second inclined surface 421, so that the second slider 430 can slide with respect to the first slider 420. As shown in fig. 9, under the lateral abutment of the driving block 410, the second slider 430 moves upward along the second inclined surface 421, driving the spindle 02 to rotate counterclockwise. Until the straight wall of the shaft core 02 abuts against the end face of the second slider 430, the shaft core 02 reaches a preset installation angle (i.e., a vertical state).
As shown in fig. 10, the curved wall of the shaft 02 abuts against the second stopper rod 450, the straight wall of the shaft 02 abuts against the first stopper rod 440, and the curved wall of the shaft 02 is separated from the end surface of the second slider 430. At this time, the contact surface of the first stopper rod 440 and the first push rod 441 is offset from the first inclined surface 411, the contact surface of the second stopper rod 450 and the second push rod 451 is offset from the second inclined surface 421, and the first slider 420 and the second slider 430 cannot slide. The shaft 02 rotates clockwise under the pressing force of the second slider 430 until a preset installation angle (i.e., a vertical state) is reached.
In the embodiment, the sliding of the first slider 420 and the second slider 430 is restricted by providing the first stopper rod 440, the second stopper rod 450, the first jack 441, the second jack 451, and the like. When the shaft core 02 is in different deflection states and is in contact with the second slider 430, the pressing conditions of the first stop lever 440 and the second stop lever 450 are also different, so that the sliding conditions of the second slider 430 are different. The sliding condition of the second slider 430 is adapted to the deflection state of the spindle 02, thereby ensuring that the spindle 02 can be rotated to the installation angle with the shortest path.
Further, in the solution of the present embodiment, the horizontal distance between the first stop lever 440 and the second stop lever 450 is set to be equal to the distance between the two straight walls of the shaft core 02, and the center line between the first stop lever 440 and the second stop lever 450 passes through the rotation center of the shaft core 02, so that the shaft core 02 can trigger the first stop lever 440 and the second stop lever 450 to rotate in the shortest path as long as the shaft core 02 is not in a state completely perpendicular to the installation angle, even if the offset degree of the shaft core 02 is large.
As shown in fig. 3 to 4, in the area corresponding to the second slider 430 and the first stopper rod 440, a U-shaped through groove 436 is formed on the second slider 430 to prevent the first stopper rod 440 and the second slider 430 from interfering when the second slider 430 slides along the second inclined surface 421. The first spring 442 and the second spring 452 may preferably be configured as compression springs. The ends of the first and second stopper rods 440, 450 facing the shaft core 02 are preferably provided in a hemispherical shape to reduce the risk of wear of the first and second stopper rods 440, 450 and the shaft core 02. The rod bodies of the first and second stopper rods 440 and 450, the first and second push rods 441 and 451 may be partially configured as rectangular rods to prevent the first and second stopper rods 440 and 450, and the first and second push rods 441 and 451 from rotating.
As shown in fig. 3-4, in some embodiments, the drive block 410 may include a first slide plate 412, a second slide plate 413, a third slide plate 414 stacked one on top of the other, the first slide plate 412, the second slide plate 413, and the third slide plate 414 being connected together by studs and nuts. The second slider 430 may include a fourth slider 431, a fifth slider 432, and a sixth slider 433 stacked one on top of the other, the first and second stopper rods 440 and 450 penetrating the fifth slider 432, the fourth slider 431, the fifth slider 432, and the sixth slider 433 being connected together by studs and nuts as well.
The wall surface of the first slider 420 facing the driving block 410 is provided with a first sliding groove 422, and the driving block 410 is provided with a corresponding first guide block 415. The first guide block 415 is movably disposed in the first slide groove 422, and a third spring 416 is disposed between the first guide block 415 and the first slide groove 422. The second inclined surface 421 is provided with a second sliding groove 423, and the second slider 430 is provided with a corresponding second guide block 434. The second guide block 434 is movably disposed in the second sliding groove 423, and a fourth spring 435 is disposed between the second guide block 434 and the second sliding groove 423.
According to the scheme of the embodiment, the first sliding groove 422 and the second sliding groove 423 are formed in the first sliding block 420, the corresponding first guide block 415 and the corresponding second guide block 434 are respectively formed in the driving block 410 and the second sliding block 430, and the third spring 416 and the fourth spring 435 are arranged, so that on one hand, automatic resetting of the first sliding block 420 and the second sliding block 430 is realized, practicability is improved, and on the other hand, the sliding of the first sliding block 420 and the second sliding block 430 is guided, and stability is further improved.
In some preferred embodiments, the third spring 416 and the fourth spring 435 may be configured as compression springs.
The spring constant and the initial deformation amount of the third spring 416 and the fourth spring 435 are equal, and the inclination angles of the first inclined surface 411 and the second inclined surface 421 are different.
When the shaft core 02 abuts against the second slider 430 in a state completely perpendicular to the mounting angle, the contact surface of the first stopper rod 440 and the first jack 441 coincides with the first inclined surface 411, and the contact surface of the second stopper rod 450 and the second jack 451 coincides with the second inclined surface 421. At this time, both the first slider 420 and the second slider 430 may slide. Since the elastic coefficients and initial deformation amounts of the third spring 416 and the fourth spring 435 are equal (i.e., when neither the first slider 420 nor the second slider 430 is slid, the elastic force of the third spring 416 applied to the first guide block 415 and the elastic force of the fourth spring 435 applied to the second guide block 434 are equal), the inclination angles of the first inclined surface 411 and the second inclined surface 421 are different, and one of the first slider 420 and the second slider 430 is slid first under the pressing force of the driving block 410.
As shown in fig. 7, in the solution of the present embodiment, the inclination angle of the first inclined surface 411 is larger than the inclination angle of the second inclined surface 421. Under the pressing of the driving block 410, the first slider 420 moves downward along the first inclined surface 411 first, and drives the second slider 430 to move downward synchronously, so that the shaft core 02 rotates clockwise. After the shaft core 02 rotates clockwise, the second limiting rod 450 is pressed, so that the second limiting rod 450 and the second ejector rod 451 retract inwards, the contact surface between the second limiting rod 450 and the second ejector rod 451 is staggered from the second inclined surface 421, and the second sliding block 430 is prevented from sliding relative to the first sliding block 420. Under the continuous pressing of the driving block 410, the first slider 420 drives the second slider 430 to continuously move downward along the first inclined surface 411, and drives the shaft core 02 to continuously rotate clockwise until the shaft core 02 reaches a preset installation angle (i.e., a vertical state).
Since the paths of rotation of the shaft core 02 from any direction to the installation angle are equal when the shaft core 02 is completely perpendicular to the preset installation angle, the magnitudes of the inclination angles of the first inclined surface 411 and the second inclined surface 421 may be arbitrarily set. In some embodiments, the first inclined surface 411 may have an inclination angle greater than that of the second inclined surface 421, the first slider 420 slides with respect to the driving block 410, and the second slider 430 is fixed with respect to the first slider 420. In other embodiments, the angle of the first inclined surface 411 may be smaller than the angle of the second inclined surface 421, the second slider 430 slides relative to the first slider 420, and the first slider 420 is fixed relative to the driving block 410.
The length of the end surface of the second slider 430 facing the shaft core 02 in the horizontal direction is longer than the arc length of the single-side curved wall of the shaft core 02.
In the solution of this embodiment, the length of the end face of the second slider 430 facing the shaft core 02 is set to be greater than the curved arc length of the shaft core 02, so that when the shaft core 02 abuts against the second slider 430 in any state and rotates under the driving of the second slider 430, the length of the end face of the second slider 430 is enough for the curved wall of the shaft core 02 to rotate until the curved wall is separated, thereby ensuring the adjusting effect of the shaft core 02.
The adjustment assembly 400 is further configured to repeatedly clamp the mandrel 02 a plurality of times under the drive of the drive assembly 500.
In some preferred embodiments, the adjustment assembly 400 is configured to repeatedly clamp the shaft 02 a plurality of times, i.e., to perform a plurality of positioning adjustments to the shaft 02, thereby ensuring that the shaft 02 is at a predetermined mounting angle, further improving the accuracy of assembly of the shaft 02 and the gear 03. Wherein, the multiple times refer to two or more times.
The pretension assembly 200 may generally include a support plate 210 and two clamp blocks 220. The support plate 210 is disposed on the base 100. Two clamping blocks 220 are movably disposed on the support plate 210. The two clamping blocks 220 are symmetrically arranged on two sides of the damper main body 01, and the end face of each clamping block 220 facing the damper main body 01 is an arc-shaped surface, and the radian of the arc-shaped surface is consistent with that of the damper main body 01.
According to the scheme of the embodiment, the end face of the clamping block 220 is set to be an arc-shaped face matched with the damper main body 01, so that the end face of the clamping block 220 can be better attached to the structure of the damper main body 01, and the clamping effect is improved.
In some preferred embodiments, the clamp block 220 may be driven by an electric cylinder or a telescopic rod.
The drive assembly 500 may generally include a drive motor 510 and a telescoping mechanism 520. One end of the telescopic mechanism 520 is connected to the driving motor 510, and the other end is connected to the adjustment assembly 400. The telescopic mechanism 520 is configured to drive the adjusting assembly 400 toward or away from the spindle 02 under the drive of the drive motor 510.
According to the scheme of the embodiment, the motor 510 and the telescopic mechanism 520 are utilized to drive the adjusting assembly 400 to move, so that the structure is simple, the maintenance cost is convenient, and the operation is stable and reliable.
The specific working process of the automatic damper assembly device provided by the invention is described with reference to the above embodiments:
First, the damper main body 01 is assembled and placed on the base 100. Thereafter, the pretensioning assembly 200 clamps the damper body 01.
The motor 510 is started to drive the telescopic mechanism 520 to drive the driving block 410 to approach the shaft core 02. The driving block 410 pushes the first slider 420 and the second slider 430 to be close to the shaft core 02 synchronously until the shaft core 02 abuts against the second slider 430. After the shaft core 02 and the second slider 430 are abutted, the first limiting rod 440 and the second limiting rod 450 are positioned at different positions under the abutment of the shaft core 02, so that the degrees of freedom of the first slider 420 or the second slider 430 are different. The driving block 410 continuously presses the first slider 420 and the second slider 430, so that the second slider 430 slides relative to the first slider 420, or the second slider 430 slides relative to the driving block 410 under the driving of the first slider 420. When the second slider 430 slides, the shaft 02 is driven to rotate under the friction action until the shaft 02 rotates to a preset installation angle. After the shaft core 02 rotates to the installation angle, the motor 510 drives the telescopic mechanism 520 reversely, so that the telescopic mechanism 520 drives the driving block 410 to be far away from the shaft core 02, and the first sliding block 420 or the second sliding block 430 is reset.
Finally, the mechanical arm 300 grips the gear 03 and mounts the gear 03 to the spindle 02.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the present invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
