Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a novel damping mechanism and a sliding plate conveying system. Background Technology

[0002] In automotive assembly lines, sliding plates are a core type of automated conveying equipment. Their flat surfaces transport workpieces from one assembly station to the next, enabling streamlined operations, and operators can stand on them to work. In practical applications, adjacent sliding plates must be tightly connected front to back without gaps; otherwise, there is a risk of falls for those standing on them. Existing technology uses an electrically driven damping mechanism on the side of the sliding plate track. In this mechanism, a resistance wheel driven by a geared motor presses against the sliding plate being driven from the side, reducing its speed and eliminating the gap between it and the adjacent sliding plate. However, this electrically driven damping mechanism is complex, has many components, and is very expensive. Therefore, developing a simpler damping mechanism that reduces equipment costs is a problem that needs to be solved. Utility Model Content

[0003] This utility model provides a novel damping mechanism and a sliding plate conveying system to simplify the structure of the damping mechanism and reduce production costs.

[0004] To achieve the above objectives, in one aspect, this utility model provides a novel damping mechanism, including a resistance wheel, a resistance wheel mounting base, and a horizontally arranged cylinder; the cylinder includes a cylinder body and a piston rod, the resistance wheel is hinged to the rear end of the resistance wheel mounting base, the cylinder body is hinged to the front end of the resistance wheel mounting base, the head end of the piston rod is connected to the resistance wheel through a first hinge shaft, and the first hinge shaft does not coincide with the wheel axle of the resistance wheel; the side of the resistance wheel is a damping rim.

[0005] Furthermore, the cylinder is a double-acting cylinder. When the first hinge shaft rotates from back to front, the piston rod is in the extended state, and when the first hinge shaft rotates from front to back, the piston rod is in the retracted state.

[0006] Furthermore, the new damping mechanism also includes a fixed seat located below the resistance wheel mounting base, with the middle part of the resistance wheel mounting base hinged to the fixed seat, and a thrust device provided between the rear end of the resistance wheel mounting base and the fixed seat.

[0007] Furthermore, the thrust device includes a push rod and a spring sleeved on the outside of the push rod; a vertical baffle is provided on the fixed base, and a through hole is provided on the baffle. The inner end of the push rod is hinged to the resistance wheel mounting base, the outer end of the push rod passes through the through hole, and the spring is located between the resistance wheel mounting base and the baffle.

[0008] Furthermore, a retaining ring is fitted on the push rod. The retaining ring is larger than the through hole and is located outside the baffle.

[0009] Furthermore, the push rod is also fitted with a spring seat and a locking nut for locking the spring seat, with the spring seat pressed against the side of the spring.

[0010] Furthermore, the spring is a rectangular spring.

[0011] Furthermore, a spherical bearing is connected to the inner end of the push rod, and the push rod is hinged to the resistance wheel mounting seat through the spherical bearing.

[0012] Furthermore, an indicator plate for indicating the spring position is connected to the spring seat, and a scale for displaying the spring compression is provided on the fixed seat, corresponding to the indicator plate, and the scale is located below the indicator plate.

[0013] On the other hand, this utility model embodiment also provides a skateboard conveying system, including a skateboard track, a skateboard running along the skateboard track, a drive mechanism, and a novel damping mechanism as described above. The drive mechanism and the novel damping mechanism are both located on the side of the skateboard track, the drive mechanism is located in front of the novel damping mechanism, and the damping wheel flange can contact the edge of the skateboard.

[0014] The above technical solution has the following beneficial effects:

[0015] This novel damping mechanism utilizes a resistance wheel to push against the side of the slide plate, thus damping it. Without altering the slide plate's direction of travel, it appropriately reduces the speed of the slide plate as it passes through the damping mechanism, preventing gaps between adjacent slide plates and meeting production requirements. This solution uses a cylinder instead of the geared motor found in existing technologies, significantly reducing costs. Furthermore, the pneumatic approach eliminates the need for frequency converters and other electrical equipment, further lowering costs.

[0016] In addition, replacing the relatively bulky geared motor with a lightweight cylinder can significantly reduce the overall weight of the equipment, making it easier to install and use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, this utility model embodiment provides a novel damping mechanism, including a resistance wheel 1, a resistance wheel mounting base 6, and a horizontally arranged cylinder; the cylinder includes a cylinder body 2 and a piston rod 3, the resistance wheel 1 is hinged to the rear end of the resistance wheel mounting base 6, the cylinder body 2 is hinged to the front end of the resistance wheel mounting base 6, the head end of the piston rod 3 is connected to the resistance wheel 1 through a first hinge shaft 4, and the first hinge shaft 4 does not coincide with the wheel axle of the resistance wheel 1; the side of the resistance wheel 1 is a damping rim 18.

[0025] To solve the aforementioned problems, in this technical solution, such as Figure 1As shown, a novel pneumatic damping mechanism is installed on the side of the slide plate 16 to achieve deceleration adjustment of the slide plate 16, thereby avoiding gaps between two adjacent slide plates. The drive mechanism 17 pushes the slide plate 16 along the track in a backward-forward direction, while the damping wheel rim 18 contacts the edge of the slide plate 16 that has disengaged from the drive mechanism 17. The frictional force drives the resistance wheel 1 to rotate, and the rotation of the resistance wheel 1 is reacted by the cylinder, thereby generating damping and achieving deceleration adjustment of the slide plate 16. This ensures that there is no gap between the slide plate 16 and the adjacent slide plate 16 (the one being pushed by the drive mechanism 17). Automobile assembly workshops are equipped with factory air (shared compressed air) pipelines, so the air source for driving the cylinder is readily available.

[0026] To generate sufficient damping, the damping rim 18 can be made of rubber, that is, the resistance wheel 1 is a rubber-coated wheel. This will increase the friction between it and the edge of the skateboard 16, improve the damping effect, and prevent hard contact from causing wear to the skateboard 16.

[0027] like Figure 1 As shown, the overall arrangement of the cylinder is roughly parallel to the running direction of the slide plate 16 (ignoring its swing angle during movement). The end of the cylinder body 2 is connected to the front end of the resistance wheel mounting seat 6 via the second hinge shaft 5, while the head of the piston rod 3 is connected to the resistance wheel 1 via the first hinge shaft 4. An eccentric structure is formed between the first hinge shaft 4 and the resistance wheel 1. This eccentric design ensures that when the resistance wheel 1 is pushed and rotated by the slide plate 16, the first hinge shaft 4 rotates synchronously. When the rotation direction of the first hinge shaft 4 is opposite to the movement trend of the piston rod 3, the piston rod 3 will inevitably exert a blocking effect on the first hinge shaft 4, thereby causing the resistance wheel 1 to dampen the slide plate 16. During this process, the cylinder does not stop the movement of the slide plate 16, nor does it change the direction of movement of the slide plate 16. Therefore, the cylinder should be reasonably selected and configured so that the thrust of the piston rod 3 is not too large and affects the normal operation of the slide plate 16, but only plays a damping role.

[0028] In this technical solution, a cylinder is used instead of the electromagnetic force of the existing technology to generate a reaction force on the slide plate 16. In this solution, the power device is a cylinder, which has a simple structure and few parts, greatly reducing the equipment cost. Furthermore, due to its simple structure, the probability of equipment failure is also greatly reduced, ensuring stable production operation.

[0029] Furthermore, such as Figure 2 , Figure 3 As shown, if the piston rod 3 is in the extended state, it only moves the first hinge shaft 4 in the upper half-cycle (i.e., the first hinge shaft 4 moves from...). Figure 3 The position shown is towards Figure 2During the rotation at the position shown, a blocking effect is generated, while the first hinge shaft 4 moves in the lower half of the cycle (i.e., the first hinge shaft 4 moves from...). Figure 2 The position shown is towards Figure 3 During the rotation process (as shown), no blocking effect is generated. Therefore, a double-acting cylinder should be selected, and the control components (such as a two-position five-way directional valve) should be appropriately configured so that when the first hinge shaft 4 rotates from back to front, the piston rod 3 is in the extended state, blocking the first hinge shaft 4; while when the first hinge shaft 4 rotates from front to back, the piston rod 3 is in the retracted state. At this time, the running trend of the piston rod 3 is again opposite to the running trend of the first hinge shaft 4, thus generating a damping effect again. Therefore, by reasonably setting the cylinder action in each rotation cycle of the resistance wheel 1, a better effect can be achieved.

[0030] Furthermore, the novel damping mechanism also includes a fixed seat 8 located below the resistance wheel mounting seat 6. The middle part of the resistance wheel mounting seat 6 is hinged to the fixed seat 8, and a thrust device is also provided between the rear end of the resistance wheel mounting seat 6 and the fixed seat 8. The resistance wheel mounting seat 6 is a load-bearing component. After its middle part is hinged to the fixed seat 8 via a third hinge shaft 7, the resistance wheel mounting seat 6 can swing around the third hinge shaft 7 during application, achieving flexible contact between the resistance wheel 1 and the sliding plate 16.

[0031] After the resistance wheel mounting base 6 can swing, in order to prevent the resistance wheel 1 from not making proper contact with the skateboard 16 and thus failing to perform its intended function, an additional thrust device can be set up. The thrust device applies a continuous preload to the resistance wheel 1, which can ensure that the resistance wheel 1 is pressed tightly against the skateboard 16.

[0032] Furthermore, for the specific structure of the thrust device, please refer to [link / reference needed]. Figure 1 It includes a push rod 9 and a spring 11 sleeved on the outside of the push rod 9; a vertical baffle 14 is provided on the fixed base 8, and a through hole is opened on the baffle 14. The inner end of the push rod 9 is hinged to the resistance wheel mounting base 6, and the outer end of the push rod 9 passes through the through hole. The spring 11 is located between the resistance wheel mounting base 6 and the baffle 14. By pre-compressing the spring 11, a spring force can be generated along the length direction of the push rod 9. Since the rear end of the spring 11 is pressed against the baffle 14, and the baffle 14 is fixedly set, the spring force will push the resistance wheel mounting base 6 to swing towards the slide plate 16, thereby pressing the resistance wheel 1 against the slide plate 16.

[0033] Furthermore, a retaining ring 13 is fitted onto the push rod 9. The retaining ring 13 is larger than the through hole and is located outside the baffle 14. A locking nut is also provided outside the retaining ring 13. The function of the retaining ring 13 is to prevent the outer end of the push rod 9 from detaching from the baffle 14 due to excessive swinging of the resistance wheel mounting seat 6, thus playing a limiting role. In particular, when the compression of the spring 11 is large and the inner end is not crossed by the slide plate 16, the retaining ring 13 needs to "pull" the push rod 9 from the outer end.

[0034] Furthermore, a spring seat 10 is fitted onto the push rod 9, which is tightly fitted against the inner side of the spring 11. A locking nut is also provided on the inner side of the spring seat 10. When necessary, the position of the spring seat 10 can be changed by adjusting the locking nut, thereby changing the compression of the spring 11 and adjusting the elastic force.

[0035] Furthermore, spring 11 is a rectangular spring. Compared with ordinary cylindrical springs, springs with rectangular cross-sections have a higher elastic coefficient. Under the condition of a certain required elastic force, the size of spring 11 can be reduced, thus reducing space occupation.

[0036] Furthermore, a spherical bearing is connected to the inner end of the push rod 9, and the push rod 9 is hinged to the resistance wheel mounting seat 6 through the spherical bearing. The spherical bearing has self-aligning capability, allowing the connected components to achieve flexible relative rotation or oscillation within a certain angle range, which can effectively compensate for errors and is more suitable for field applications.

[0037] Furthermore, an indicator plate 12 for indicating the position of the spring 11 is connected to the spring seat 10, and a scale 15 corresponding to the indicator plate 12 for displaying the compression of the spring 11 is provided on the fixed seat 8, with the scale 15 located below the indicator plate 12. By observing the projection position of the indicator plate 12 on the scale 15, the compression of the spring 11 can be intuitively determined, facilitating quick adjustment of the preload.

[0038] like Figure 4 As shown, this embodiment of the invention also provides a skateboard conveying system, including a skateboard track, a skateboard 16 running along the skateboard track, a drive mechanism 17, and a novel damping mechanism as described above. Both the drive mechanism 17 and the novel damping mechanism are disposed to the side of the skateboard track, with the drive mechanism 17 located in front of the novel damping mechanism, and the damping rim 18 capable of contacting the edge of the skateboard 16. The drive mechanism 17 is positioned at the rear to propel the skateboard 16 forward, while the novel damping mechanism is positioned at the front to generate resistance to the skateboard 16 that has disengaged from the drive mechanism 17.
