Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and particularly to an automatic assembly device for a damper. Background Art

[0002] A gear damper is a type of rotary damper, also known as a damping gear. Through the principle of gear-rack meshing, the gear damper can be applied not only to rotary motion but also to linear motion, with a wide range of applications. Among them, the shaft core and the gear of the damper are important components for transmitting power and torque inside the damper. The installation accuracy and stability of the two directly determine whether the damper can operate smoothly according to the design requirements. Once there is a deviation in the assembly of the shaft core and the gear, it may lead to poor operation of the damper, abnormal vibration and noise, and even mechanical failures, seriously affecting the normal operation and service life of the equipment. Therefore, in the assembly process of the damper, the assembly of the shaft core and the gear of the damper is extremely important.

[0003] In the prior art, before installing the gear onto the shaft core, it is necessary to install components such as the lower seat, shaft core, sealing cavity, and upper cover of the damper in sequence. During the installation of these components, the shaft core is prone to deflection, resulting in a reduction in the alignment accuracy between the shaft core and the gear during subsequent gear assembly. This not only increases the assembly difficulty and reduces the assembly efficiency but also easily leads to problems such as installation position deviation and loose connection between the shaft core and the gear. Although these problems may not be easily detected initially, after the product is put into use, they will seriously affect the performance and stability of the damper, resulting in a significant increase in the defective rate of the product and an increase in production costs.

Detailed implementation manners

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] In this article, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features, that is, including one or more of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined. When a certain feature "includes or contains" a certain or certain features it covers, unless otherwise specifically described, this indicates that other features are not excluded and other features may be further included.

[0019] Next, refer to Figures 1 to 10 to describe an automatic damper assembly device provided by the present invention.

[0020] This embodiment provides a damper automatic assembly device. The damper automatic assembly device generally may include: a base 100, a robotic arm 300, and a positioning component.

[0021] A pre-tightening component 200 is arranged on the base 100 for clamping the damper body 01; a rotatable shaft core 02 is arranged on the damper body 01. The robotic arm 300 is arranged on the base 100 for clamping a gear 03 and mounting the gear 03 onto the shaft core 02. The positioning component is arranged on the base 100 for positioning the shaft core 02 before mounting the gear 03, so that the shaft core 02 rotates to a preset mounting angle along the shortest path.

[0022] The positioning component generally may include two adjusting components 400 and two driving components 500. The two adjusting components 400 are symmetrically arranged with the rotation center of the shaft core 02 as the symmetry center, and the two driving components 500 are respectively connected to the two adjusting components 400. The two adjusting components 400 are configured to gradually approach and clamp the shaft core 02 along the same straight line under the drive of the two driving components 500; wherein, during the process of clamping the shaft core 02, when the shaft core 02 is not in the mounting angle, the two adjusting components 400 drive the shaft core 02 to rotate to the mounting angle along the shortest path. Wherein, the mounting angle is preferably set such that the straight wall of the shaft core 02 is perpendicular to the driving direction of the driving component 500.

[0023] As Figure 1 shown, the side wall of the shaft core 02 is composed of two opposite curved walls and two opposite straight walls, and a through hole adapted to the shape of the side wall of the shaft core 02 is formed on the gear 03. A column 110 adapted to the through hole of the gear 03 is arranged on the base 100, and multiple gears 03 to be assembled are sleeved on the column 110 in a specific angle in sequence. It can be understood that when the gear 03 is transferred from the column 110 to above the shaft core 02 under the clamping of the robotic arm 300 and waits for assembly, the position and angle of the gear 03 are fixed relative to the base 100.

[0024] The solution of this embodiment, by arranging a positioning component on the base 100 to position the shaft core 02 on the damper body 01 before mounting the gear 03, so that the shaft core 02 rotates to a preset mounting position, thereby improving the alignment accuracy between the shaft core 02 and the gear 03 and ensuring the smooth assembly of the shaft core 02 and the gear 03. Using the positioning component to make the shaft core 02 rotate to the preset mounting position along the shortest path can not only quickly adjust the shaft core 02 to the mounting position, improve the assembly efficiency, but also reduce the wear risk of components such as the shaft core 02 and the positioning component during the positioning process.

[0025] Furthermore, in the solution of this embodiment, by providing two driving components 500 that are symmetric about the rotation center of the shaft core 02, when the two driving components 500 clamp the shaft core 02, the plane formed by the two force lines of the shaft core 02 and the driving components 500 passes through the axis of the shaft core 02. When the shaft core 02 rotates driven by the adjusting component 400, the force on the shaft core 02 is more uniform and the rotation is more stable. Driven by the adjusting component 400, the shaft core 02 rotates to the preset installation angle along the shortest path, thereby reducing the time required for the angle adjustment of the shaft core 02, not only improving the assembly efficiency, but also reducing the wear risk of the shaft core 02 and ensuring the product quality.

[0026] Generally, the adjusting component 400 may include: a driving block 410, a first slider 420, and a second slider 430.

[0027] The driving block 410 is connected to the driving component 500 and approaches the shaft core 02 under the drive of the driving component 500. The end face of the driving block 410 facing the shaft core 02 is a first inclined surface 411. The first slider 420 is slidably arranged on the driving block 410 along the first inclined surface 411. The end face of the first slider 420 facing the shaft core 02 is a second inclined surface 421. Among them, the inclination directions of the first inclined surface 411 and the second inclined surface 421 are opposite. The second slider 430 is slidably arranged on the first slider 420 along the second inclined surface 421. The second slider 430 is configured to slide relative to the first slider 420 or slide synchronously with the first slider 420, so as to drive the shaft core 02 to rotate to the installation angle along the shortest path.

[0028] When the driving block 410 approaches the shaft core 02 under the drive of the driving component 500, it drives the first slider 420 and the second slider 430 to approach the shaft core 02 synchronously. After the second slider 430 abuts against the shaft core 02, the driving component 500 continues to press the driving block 410 closer to the shaft core 02, 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 together with the first slider 420. When the second slider 430 moves, it drives the shaft core 02 to rotate under the action of friction.

[0029] In the solution of this embodiment, by setting the inclination directions of the first inclined surface 411 and the second inclined surface 421 to be opposite, when the second slider 430 slides relative to the first slider 420 or slides synchronously with the first slider 420, it can drive the shaft core 02 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, thereby ensuring that the shaft core 02 can rotate to the installation angle along the shortest path, not only reducing the wear risk of each component, but also reducing the positioning time of the shaft core 02, and further improving the assembly efficiency.

[0030] In some preferred embodiments, the first slider 420 and the driving block 410, as well as the second slider 430 and the first slider 420, can be slidably connected through dovetail grooves.

[0031] The adjusting assembly 400 generally may further include a first limiting rod 440 and a second limiting rod 450.

[0032] One end of the first limiting rod 440 passes through the first slider 420 and extends from the end face of the second slider 430 facing the axis 02, and the other end abuts against the first ejector rod 441 in the driving block 410. A first spring 442 is provided between the first ejector rod 441 and the driving block 410; the contact surface between the first limiting rod 440 and the first ejector rod 441 is configured to coincide with the first inclined surface 411 when both the first limiting rod 440 and the second slider 430 abut against the curved wall of the axis 02. One end of the second limiting rod 450 extends from the end face of the second slider 430 facing the axis 02, and the other end abuts against the second ejector rod 451 in the first slider 420. A second spring 452 is provided between the second ejector rod 451 and the second slider 430; the contact surface between the second limiting rod 450 and the second ejector rod 451 is configured to coincide with the second inclined surface 421 when both the second limiting rod 450 and the second slider 430 abut against the curved wall of the axis 02. The first limiting rod 440 is disposed on the side of the first inclined surface 411 away from the axis 02, and the second limiting rod 450 is disposed on the side of the second inclined surface 421 away from the axis 02. The horizontal distance between the first limiting rod 440 and the second limiting rod 450 is equal to the distance between the two straight walls of the axis 02; and the center line between the first limiting rod 440 and the second limiting rod 450 passes through the rotation center of the axis 02.

[0033] When the axis 02 is in different skew states, after the axis 02 abuts against the second slider 430, the first limiting rod 440 and the second limiting rod 450 are in different positions under the pressing of the axis 02, so that the sliding states of the first slider 420 and the second slider 430 are different (that is, after the second slider 430 abuts against the axis 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 produce relative sliding).

[0034] As Figure 8As shown, the straight wall of the shaft core 02 abuts against the first limiting rod 440, and the curved wall of the shaft core 02 abuts against the second limiting rod 450. At this time, under the action of the first spring 442, the first limiting rod 440 and the first ejector rod 441 are closer to the shaft core 02. The contact surface between the first limiting rod 440 and the first ejector 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 between the second limiting rod 450 and the second ejector rod 451 coincides with the second inclined surface 421, so that the second slider 430 can slide relative to the first slider 420. As Figure 9 shown, under the lateral pressing of the driving block 410, the second slider 430 moves upward along the second inclined surface 421, driving the shaft core 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 the preset installation angle (i.e., the vertical state).

[0035] As Figure 10 shown, the curved wall of the shaft core 02 abuts against the second limiting rod 450, the straight wall of the shaft core 02 abuts against the first limiting rod 440, and the curved wall of the shaft core 02 is separated from the end face of the second slider 430. At this time, the contact surface between the first limiting rod 440 and the first ejector rod 441 is offset from the first inclined surface 411, the contact surface between the second limiting rod 450 and the second ejector rod 451 is offset from the second inclined surface 421, and neither the first slider 420 nor the second slider 430 can slide. Under the pressing of the second slider 430, the shaft core 02 rotates clockwise until it reaches the preset installation angle (i.e., the vertical state).

[0036] In the solution of this embodiment, by setting components such as the first limiting rod 440, the second limiting rod 450, the first ejector rod 441, and the second ejector rod 451, the sliding of the first slider 420 and the second slider 430 is restricted. When the shaft core 02 is in different deflected states and abuts against the second slider 430, the pressing conditions on the first limiting rod 440 and the second limiting rod 450 are also different, so that the sliding conditions of the second slider 430 are different. The sliding conditions of the second slider 430 are adapted to the deflected state of the shaft core 02, thus ensuring that the shaft core 02 can rotate to the installation angle along the shortest path.

[0037] Furthermore, in the solution of this embodiment, the horizontal distance between the first limiting rod 440 and the second limiting rod 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 limiting rod 440 and the second limiting rod 450 passes through the rotation center of the shaft core 02, so that 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, the first limiting rod 440 and the second limiting rod 450 can be triggered, and the shaft core 02 can rotate along the shortest path.

[0038] As Figures 3 - 4As shown, in the area corresponding to the second slider 430 and the first limiting rod 440, a U-shaped through groove 436 is formed on the second slider 430 to prevent interference between the first limiting rod 440 and the second slider 430 when the second slider 430 slides along the second inclined surface 421. The first spring 442 and the second spring 452 are preferably configured as compression springs. The ends of the first limiting rod 440 and the second limiting rod 450 facing the axis 02 are preferably provided as hemispherical shapes to reduce the wear risk of the first limiting rod 440, the second limiting rod 450, and the axis 02. The rod bodies of the first limiting rod 440, the second limiting rod 450, the first ejector rod 441, and the second ejector rod 451 can be partially provided as rectangular rods to prevent the first limiting rod 440, the second limiting rod 450, the first ejector rod 441, and the second ejector rod 451 from rotating.

[0039] As Figures 3 - 4 shown, in some embodiments, the drive block 410 may include a first sliding plate 412, a second sliding plate 413, and a third sliding plate 414 stacked in sequence from top to bottom. The first sliding plate 412, the second sliding plate 413, and the third sliding plate 414 are connected together by studs and nuts. The second slider 430 may include a fourth sliding plate 431, a fifth sliding plate 432, and a sixth sliding plate 433 stacked in sequence from top to bottom. The first limiting rod 440 and the second limiting rod 450 pass through the fifth sliding plate 432, and the fourth sliding plate 431, the fifth sliding plate 432, and the sixth sliding plate 433 are also connected together by studs and nuts.

[0040] A first sliding groove 422 is provided on the wall surface of the first slider 420 facing the drive block 410, and a corresponding first guide block 415 is provided on the drive block 410. The first guide block 415 is movably arranged in the first sliding groove 422, and a third spring 416 is arranged between the first guide block 415 and the first sliding groove 422. A second sliding groove 423 is provided on the second inclined surface 421, and a corresponding second guide block 434 is provided on the second slider 430. The second guide block 434 is movably arranged in the second sliding groove 423, and a fourth spring 435 is arranged between the second guide block 434 and the second sliding groove 423.

[0041] In the solution of this embodiment, by providing the first sliding groove 422 and the second sliding groove 423 on the first slider 420, providing the corresponding first guide block 415 and the second guide block 434 on the drive block 410 and the second slider 430 respectively, and providing the third spring 416 and the fourth spring 435, on the one hand, the automatic reset of the first slider 420 and the second slider 430 is realized, improving the practicability, and on the other hand, it plays a guiding role in the sliding of the first slider 420 and the second slider 430, further improving the stability.

[0042] In some preferred embodiments, the third spring 416 and the fourth spring 435 can be configured as compression springs.

[0043] The elastic coefficients and initial deformation amounts 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.

[0044] When the shaft core 02 is in contact with the second slider 430 in a state completely perpendicular to the installation angle, the contact surface of the first limit rod 440 and the first push rod 441 coincides with the first inclined surface 411, and the contact surface of the second limit rod 450 and the second push rod 451 coincides with the second inclined surface 421. At this time, the first slider 420 and the second slider 430 can both slide. Since the elastic coefficients and initial deformation amounts of the third spring 416 and the fourth spring 435 are equal (that is, when the first slider 420 and the second slider 430 are not sliding, the elastic force applied by the third spring 416 to the first guide block 415 and the elastic force applied by the fourth spring 435 to the second guide block 434 are equal), the first inclined surface 411 and the second inclined surface 421 have different inclination angles. Under the pressure of the driving block 410, one of the first slider 420 and the second slider 430 slides first.

[0045] like Figure 7 As shown, in the scheme of this embodiment, the inclination angle of the first inclined surface 411 is greater than the inclination angle of the second inclined surface 421. Under the pressure of the driving block 410, the first slider 420 first moves downward along the first inclined surface 411, driving the second slider 430 to move downward synchronously, so that the shaft core 02 rotates clockwise. After the shaft core 02 rotates clockwise, it presses the second limit rod 450, so that the second limit rod 450 and the second push rod 451 retract inward, so that the contact surface between the second limit rod 450 and the second push rod 451 and the second inclined surface 421 are staggered, thereby limiting the second slider 430 from sliding relative to the first slider 420. Under the continuous pressure of the driving block 410, the first slider 420 drives the second slider 430 to continue to move downward along the first inclined surface 411, driving the shaft core 02 to continue to rotate clockwise until the shaft core 02 reaches the preset installation angle (i.e., the vertical state).

[0046] Since the shaft core 02 is completely perpendicular to the preset installation angle, the path of the shaft core 02 rotating from any direction to the installation angle is equal, therefore, the inclination angles of the first inclined surface 411 and the second inclined surface 421 can be set arbitrarily. In some embodiments, the inclination angle of the first inclined surface 411 can be greater than the angle of the second inclined surface 421, the first slider 420 slides relative to the driving block 410, and the second slider 430 is fixed relative to the first slider 420. In other embodiments, the angle of the first inclined surface 411 can be less 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.

[0047] The length of the end face of the second slider 430 facing the axis 02 in the horizontal direction is greater than the arc length of the single-sided curved wall of the axis 02.

[0048] In the solution of this embodiment, the length of the end face of the second slider 430 facing the axis 02 is set to be greater than the arc length of the curved surface of the axis 02, so that after the axis 02 abuts against the second slider 430 in any state and rotates under the drive of the second slider 430, the end face length of the second slider 430 is sufficient for the curved wall of the axis 02 to rotate and disengage, thus ensuring the adjustment effect of the axis 02.

[0049] The adjustment assembly 400 is further configured to repeatedly clamp the axis 02 multiple times under the drive of the drive assembly 500.

[0050] In some preferred embodiments, the adjustment assembly 400 is configured to repeatedly clamp the axis 02 multiple times, that is, perform multiple positioning adjustments on the axis 02, so as to ensure that the axis 02 is in a preset installation angle, further improving the assembly accuracy of the axis 02 and the gear 03. Herein, multiple times means two or more times.

[0051] Generally, the pre-tightening assembly 200 may include a support disk 210 and two clamping blocks 220. The support disk 210 is arranged on the base 100. The two clamping blocks 220 are movably arranged on the support disk 210. The two clamping blocks 220 are symmetrically arranged on both sides of the damper body 01, and the end face of each clamping block 220 facing the damper body 01 is an arc surface, and the radian of the arc surface is consistent with the radian of the damper body 01.

[0052] In the solution of this embodiment, the end face of the clamping block 220 is set as an arc surface adapted to the damper body 01, so that the end face of the clamping block 220 can better fit the structure of the damper body 01, thereby improving the clamping effect.

[0053] In some preferred embodiments, the clamping block 220 can be driven by an electric cylinder or a telescopic rod.

[0054] Generally, the drive assembly 500 may include a drive motor 510 and a telescopic mechanism 520. One end of the telescopic mechanism 520 is connected to the drive motor 510, and the other end is connected to the adjustment assembly 400. The telescopic mechanism 520 is configured to drive the adjustment assembly 400 to approach or move away from the axis 02 under the drive of the drive motor 510.

[0055] In the solution of this embodiment, the motor 510 and the telescopic mechanism 520 are used to drive the adjustment assembly 400 to move, which not only has a simple structure and is convenient for maintenance costs, but also runs stably and reliably.

[0056] Combined with the above embodiments, the specific working process of the damper automatic assembly device provided by the present invention is described as follows: First, assemble the damper body 01 and place it on the base 100. Then, the pre-tightening assembly 200 clamps the damper body 01.

[0057] The motor 510 starts, driving 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 approach the shaft core 02 synchronously until the shaft core 02 abuts against the second slider 430. 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 pressing 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 continues to press 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 driven by the first slider 420. When the second slider 430 slides, under the action of friction, it drives the shaft core 02 to rotate until the shaft core 02 rotates to a preset installation angle. After the shaft core 02 rotates to the installation angle, the motor 510 reversely drives the telescopic mechanism 520 to make the telescopic mechanism 520 drive the driving block 410 away from the shaft core 02, and the first slider 420 or the second slider 430 resets.

[0058] Finally, the robotic arm 300 clamps the gear 03 and installs the gear 03 on the shaft core 02.

[0059] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0060] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
