Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and in particular 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. Using the principle of rack-and-pinion meshing, gear dampers can be applied not only to rotational motion but also to linear motion, giving them a wide range of applications. The damper's shaft and gears are important components for transmitting power and torque within the damper. Their installation accuracy and stability directly determine whether the damper can operate smoothly as designed. Any deviation in the assembly of the shaft and gears can cause the damper to malfunction, generate abnormal vibration and noise, and even cause mechanical failure, seriously impacting the normal operation and service life of the equipment. Therefore, during the damper assembly process, the proper assembly of the damper's shaft and gears is extremely important.

[0003] In the prior art, before the gear is mounted on the shaft, the damper's lower seat, shaft, sealing chamber, upper cover, and other components need to be installed in sequence. During the installation of these components, the shaft can easily deflect, which can reduce the alignment accuracy of the shaft and gear during subsequent gear assembly. This not only increases assembly difficulty and reduces assembly efficiency, but can also easily lead to installation position deviations and loose connections between the shaft and gear. While these problems may not be easily noticeable in the early stages, they can seriously affect the performance and stability of the damper once the product is put into use, significantly increasing the defective rate and increasing production costs.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 intended to limit the present invention.

[0029] The terms "first", "second", etc. herein are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features, that is, include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined. When a feature "includes or contains" one or more of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0030] Refer to the following Figures 1 to 10 To describe an automatic damper assembly device provided by the present invention.

[0031] This embodiment provides a damper automated assembly device, which generally includes: a base 100 , a robotic arm 300 , and a positioning assembly.

[0032] A preload assembly 200 is mounted on the base 100, used to clamp the damper body 01; a rotatable shaft core 02 is mounted on the damper body 01. A robotic arm 300 is mounted on the base 100, used to clamp the gear 03 and mount it on the shaft core 02. A positioning assembly is also mounted on the base 100, used to position the shaft core 02 before mounting the gear 03, allowing it to rotate to a predetermined installation angle using the shortest possible path.

[0033] The positioning assembly can generally include two adjustment assemblies 400 and two drive assemblies 500. The two adjustment assemblies 400 are symmetrically arranged with the rotation center of the shaft core 02 as the symmetry center, and the two drive assemblies 500 are respectively connected to the two adjustment assemblies 400. The two adjustment assemblies 400 are configured to gradually approach and clamp the shaft core 02 along the same straight line under the drive of the two drive assemblies 500; wherein, in the process of clamping the shaft core 02, when the shaft core 02 is not at the installation angle, the two adjustment assemblies 400 drive the shaft core 02 to rotate to the installation angle along the shortest path. wherein, the installation angle is preferably set so that the straight wall of the shaft core 02 is perpendicular to the driving direction of the drive assembly 500.

[0034] like Figure 1 As shown, the sidewalls of shaft core 02 are composed of two opposing curved walls and two opposing straight walls. Gear 03 is formed with a through-hole that matches the shape of the sidewalls of shaft core 02. Base 100 is provided with a column 110 that matches the shape of the through-hole of gear 03. Multiple gears 03 to be assembled are sequentially mounted on column 110 at specific angles. It is understood that when gear 03 is clamped by robotic arm 300 and transferred from column 110 to the top of shaft core 02 for assembly, the position and angle of gear 03 relative to base 100 remain fixed.

[0035] The solution of this embodiment, by providing a positioning assembly on the base 100, positions the shaft core 02 on the damper body 01 before installing the gear 03, allowing the shaft core 02 to rotate to a preset installation position, thereby improving the alignment accuracy of the shaft core 02 and the gear 03 and ensuring smooth assembly of the shaft core 02 and the gear 03. Using the positioning assembly to rotate the shaft core 02 to the preset installation position via the shortest path not only allows the shaft core 02 to be quickly adjusted to the installation position, improving assembly efficiency, but also reduces the risk of wear on the shaft core 02 and components such as the positioning assembly during the positioning process.

[0036] Furthermore, the solution of this embodiment, by providing two drive assemblies 500 symmetrically about the rotation center of the shaft core 02, ensures that when the two drive assemblies 500 clamp the shaft core 02, the plane formed by the two force lines of the shaft core 02 and the drive assemblies 500 passes through the axis of the shaft core 02. When the shaft core 02 rotates under the drive of the adjustment assembly 400, the force on the shaft core 02 is more even, and the rotation is more stable. Driven by the adjustment assembly 400, the shaft core 02 rotates to the preset installation angle in the shortest possible path, thereby reducing the time required to adjust the angle of the shaft core 02. This not only improves assembly efficiency but also reduces the risk of wear on the shaft core 02, ensuring product quality.

[0037] The adjustment assembly 400 may generally include: a driving block 410 , a first slider 420 , and a second slider 430 .

[0038] The driving block 410 is connected to the driving assembly 500 and is driven by the driving assembly 500 to approach the shaft core 02. 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 arranged 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. 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, thereby driving the shaft core 02 to rotate to the installation angle along the shortest path.

[0039] When the drive block 410 approaches the shaft core 02 under the drive assembly 500, it drives the first slider 420 and the second slider 430 to synchronously approach the shaft core 02. After the second slider 430 contacts the shaft core 02, the drive assembly 500 continues to press the drive block 410 toward the shaft core 02, causing the second slider 430 to slide relative to the first slider 420, or the second slider 430 to slide relative to the drive block 410 along with the first slider 420. As the second slider 430 moves, friction causes the shaft core 02 to rotate.

[0040] In the solution of this embodiment, the first inclined surface 411 and the second inclined surface 421 are set to have opposite inclination directions, so that 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 and the deflection direction of the shaft core 02 are adapted to each other, thereby ensuring that the shaft core 02 can be rotated to the installation angle by the shortest path, which not only reduces the wear risk of each component, but also reduces the positioning time of the shaft core 02, thereby improving the assembly efficiency.

[0041] 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 , may be slidably connected via dovetail grooves.

[0042] The adjustment assembly 400 may generally further include a first limiting rod 440 and a second limiting rod 450 .

[0043] One end of the first limiting rod 440 passes through the first slider 420 and extends from the second slider 430 toward the end face of the shaft core 02. The other end abuts against the first push rod 441 in the driving block 410. A first spring 442 is interposed between the first push rod 441 and the driving block 410. The contact surface between the first limiting rod 440 and the first push 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 shaft core 02. One end of the second limiting rod 450 extends from the second slider 430 toward the end face of the shaft core 02. The other end abuts against the second push rod 451 in the first slider 420. A second spring 452 is interposed between the second push rod 451 and the second slider 430. The contact surface between the second limiting rod 450 and the second push 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 shaft core 02. The first limiting rod 440 is disposed on the side of the first inclined surface 411 away from the shaft core 02, and the second limiting rod 450 is disposed on the side of the second inclined surface 421 away from the shaft core 02. The horizontal spacing between the first limiting rod 440 and the second limiting rod 450 is equal to the spacing between the two straight walls of the shaft core 02; and the centerline between the first limiting rod 440 and the second limiting rod 450 passes through the rotation center of the shaft core 02.

[0044] When the shaft core 02 is in different deflection states, after the shaft core 02 abuts against the second slider 430, the first limit rod 440 and the second limit rod 450 are in different positions under the pressure of the shaft core 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 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 each other).

[0045] like Figure 8 As 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 push rod 441 are closer to the shaft core 02. The contact surface of the first limiting rod 440 and the first push rod 441 and the first inclined surface 411 are staggered, so that the first slider 420 cannot slide relative to the driving block 410. The contact surface of the second limiting rod 450 and the second push rod 451 and the second inclined surface 421 coincide with each other, so that the second slider 430 can slide relative to the first slider 420. As shown Figure 9 As shown, under the lateral pressure 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 contacts the end surface of the second slider 430, and the shaft core 02 reaches the preset installation angle (i.e., vertical state).

[0046] like Figure 10 As shown, the curved wall of shaft core 02 abuts against second limiting rod 450, while the straight wall of shaft core 02 abuts against first limiting rod 440, and the curved wall of shaft core 02 is separated from the end surface of second slider 430. At this point, the contact surface between first limiting rod 440 and first push rod 441 and first inclined surface 411 are offset, while the contact surface between second limiting rod 450 and second push rod 451 and second inclined surface 421 are offset, preventing both first and second sliders 420 and 430 from sliding. Under the pressure of second slider 430, shaft core 02 rotates clockwise until it reaches the preset installation angle (i.e., vertical position).

[0047] This embodiment restricts the sliding movement of the first and second sliders 420 and 430 by providing components such as a first limiting rod 440, a second limiting rod 450, a first push rod 441, and a second push rod 451. Depending on the deflection of the shaft core 02, when it contacts the second slider 430, the pressure applied to the first and second limiting rods 440 and 450 varies, resulting in different sliding movements of the second slider 430. The sliding movement of the second slider 430 is coordinated with the deflection of the shaft core 02, ensuring that the shaft core 02 can rotate to the installation angle via the shortest possible path.

[0048] Furthermore, in the solution of this embodiment, the horizontal spacing between the first limiting rod 440 and the second limiting rod 450 is set to be equal to the spacing 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 degree of offset of the shaft core 02 is large, the first limiting rod 440 and the second limiting rod 450 can be triggered to make the shaft core 02 rotate along the shortest path.

[0049] like Figure 3-4 As shown, a U-shaped through groove 436 is formed on the second slider 430 in the area corresponding to the second slider 430 and the first limiting rod 440 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 can preferably be configured as compression springs. The ends of the first limiting rod 440 and the second limiting rod 450 facing the shaft core 02 are preferably configured as hemispherical to reduce the risk of wear on the first limiting rod 440, the second limiting rod 450 and the shaft core 02. The rod bodies of the first limiting rod 440, the second limiting rod 450, the first push rod 441 and the second push rod 451 can be partially configured as rectangular rods to prevent the first limiting rod 440, the second limiting rod 450, the first push rod 441 and the second push rod 451 from rotating.

[0050] like Figure 3-4 As shown, in some embodiments, the driving block 410 may include a first slide 412, a second slide 413, and a third slide 414 stacked in sequence, connected together by studs and nuts. The second slider 430 may include a fourth slide 431, a fifth slide 432, and a sixth slide 433 stacked in sequence, with a first limiting rod 440 and a second limiting rod 450 passing through the fifth slide 432. The fourth slide 431, the fifth slide 432, and the sixth slide 433 are also connected together by studs and nuts.

[0051] A first sliding groove 422 is provided on the wall of the first slider 420 facing the driving block 410, and a corresponding first guide block 415 is provided on the driving block 410. The first guide block 415 is movably disposed in the first sliding groove 422, and a third spring 416 is interposed 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 disposed in the second sliding groove 423, and a fourth spring 435 is interposed between the second guide block 434 and the second sliding groove 423.

[0052] The solution of this embodiment is to provide a first slide groove 422 and a second slide groove 423 on the first slider 420, and provide corresponding first guide blocks 415 and second guide blocks 434 on the driving block 410 and the second slider 430, respectively, and provide a third spring 416 and a fourth spring 435. On the one hand, the automatic reset of the first slider 420 and the second slider 430 is achieved, thereby improving practicality. On the other hand, the sliding of the first slider 420 and the second slider 430 is guided, thereby further improving stability.

[0053] In some preferred embodiments, the third spring 416 and the fourth spring 435 may be configured as compression springs.

[0054] 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.

[0055] When the shaft core 02 abuts the second slider 430 at a position completely perpendicular to the installation angle, the contact surfaces of the first limiting rod 440 and the first push rod 441 coincide with the first inclined surface 411, and the contact surfaces of the second limiting rod 450 and the second push rod 451 coincide with the second inclined surface 421. At this point, both the first slider 420 and the second slider 430 can slide. Because the elastic coefficients and initial deformations 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 sliding, the spring force applied by the third spring 416 to the first guide block 415 and the spring force applied by the fourth spring 435 to the second guide block 434 are equal), and the first inclined surface 411 and the second inclined surface 421 have different inclination angles, one of the first slider 420 or the second slider 430 slides first under the pressure of the driving block 410.

[0056] like Figure 7 As shown, in 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, causing the shaft core 02 to rotate clockwise. After the shaft core 02 rotates clockwise, it presses against the second limiting rod 450, causing the second limiting rod 450 and the second push rod 451 to retract inward. This causes the contact surface between the second limiting rod 450 and the second push rod 451 and the second inclined surface 421 to be offset, thereby preventing the second slider 430 from sliding relative to the first slider 420. Under the continued pressure of the driving block 410, the first slider 420 drives the second slider 430 to continue moving downward along the first inclined surface 411, driving the shaft core 02 to continue rotating clockwise until the shaft core 02 reaches the preset installation angle (i.e., the vertical position).

[0057] 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 arbitrarily set. 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.

[0058] The length of the end surface of the second sliding block 430 facing the shaft core 02 in the horizontal direction is greater than the arc length of the single-sided curved wall of the shaft core 02 .

[0059] In the solution of this embodiment, the end face length of the second slider 430 toward the shaft core 02 is set to be greater than the arc length of the curved surface of the shaft core 02, so that after the shaft core 02 abuts against the second slider 430 in any state, when it 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 shaft core 02 to rotate and disengage, thereby ensuring the adjustment effect of the shaft core 02.

[0060] The adjustment assembly 400 is also configured to repeatedly clamp the shaft core 02 multiple times under the drive of the drive assembly 500.

[0061] In some preferred embodiments, the adjustment assembly 400 is configured to repeatedly clamp the shaft core 02 multiple times, i.e., perform multiple positioning adjustments on the shaft core 02, thereby ensuring that the shaft core 02 is at a preset installation angle, further improving the assembly accuracy of the shaft core 02 and the gear 03. Here, multiple times refers to two or more times.

[0062] The preload assembly 200 generally includes a support plate 210 and two clamping blocks 220. The support plate 210 is mounted on the base 100. The two clamping blocks 220 are movably mounted on the support plate 210. The two clamping blocks 220 are symmetrically arranged on either side of the damper body 01. The end surface of each clamping block 220 facing the damper body 01 is a curved surface, and the curvature of the curved surface matches the curvature of the damper body 01.

[0063] In the solution of this embodiment, the end surface of the clamping block 220 is set to an arc-shaped surface adapted to the damper body 01, so that the end surface of the clamping block 220 can better fit the structure of the damper body 01, thereby improving the clamping effect.

[0064] In some preferred embodiments, the clamping block 220 can be driven by an electric cylinder or a telescopic rod.

[0065] The drive assembly 500 generally includes 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 move the adjustment assembly 400 toward or away from the shaft core 02 under the drive of the drive motor 510.

[0066] The solution of this embodiment utilizes the motor 510 and the telescopic mechanism 520 to drive the adjustment assembly 400 to move, which not only has a simple structure and is convenient for maintenance costs, but also operates stably and reliably.

[0067] The specific working process of the damper automatic assembly device provided by the present invention is described in combination with the above embodiments:

[0068] First, the damper body 01 is assembled and placed on the base 100. Then, the pre-tightening assembly 200 clamps the damper body 01.

[0069] The motor 510 starts, driving the telescopic mechanism 520 to drive the drive block 410 toward the shaft core 02. The drive block 410 pushes the first slider 420 and the second slider 430 to move synchronously toward the shaft core 02 until the shaft core 02 abuts the second slider 430. After the shaft core 02 and the second slider 430 abut, the first limiting rod 440 and the second limiting rod 450 are in different positions under the pressure of the shaft core 02, resulting in different degrees of freedom for the first slider 420 or the second slider 430. The drive block 410 continues to press the first slider 420 and the second slider 430, causing the second slider 430 to slide relative to the first slider 420, or the second slider 430 to slide relative to the drive block 410 driven by the first slider 420. When the second slider 430 slides, it drives the shaft core 02 to rotate under the action of friction until the shaft core 02 rotates to the preset installation angle. After the shaft core 02 rotates to the installation angle, the motor 510 drives the telescopic mechanism 520 in the reverse direction, so that the telescopic mechanism 520 drives the driving block 410 away from the shaft core 02, and the first slider 420 or the second slider 430 is reset.

[0070] Finally, the robot arm 300 clamps the gear 03 and installs the gear 03 onto the shaft core 02 .

[0071] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
