Abstract

The present invention relates to a workbench applied to a pipeline production device, which comprises a sliding base for sliding on a slide rail of the pipeline production device; a fixing part for installing a jig is arranged on the sliding base; and a damping mechanism is further included. The damping mechanism comprises a base, a damping component, a rotating shaft and a synchronous pulley. The base is fixedly connected with the sliding base. The damping component is arranged on the base. The transmission shaft is connected with the damping component. The synchronous pulley is installed on the transmission shaft and is used for meshing with a conveyor belt of the pipeline production device. Through the cooperation of the damping mechanism and the synchronous pulley, in normal transmission, the synchronous pulley does not rotate, and is conveyed to the working station by the conveyor belt; when it is fixed at the working station or there is accumulation, the conveyor belt continues to rotate. When the rotational force is greater than the resistance generated by the damping mechanism, the synchronous pulley rotates without affecting the conveyor belt.

Description

Technical Field

[0001] The present invention relates to production machinery and equipment, and particularly to a workbench mechanism of an assembly line production equipment. Background Art

[0002] In traditional assembly line production equipment, several workstations are set up, and the workpieces are conveyed to each workstation in sequence by a conveying mechanism to achieve assembly line production; while in semi-automatic or fully automatic production line equipment, several workbenches are set up, and the workpieces to be processed are placed on the fixtures of the workbenches. The conveying mechanism sends the workbenches to the workstations, and the workers or production action mechanisms at the workstations process the workpieces.

[0003] Although such a mode realizes semi-automatic or fully automatic production, when one of the workstations is stacked, it is necessary to stop the conveying mechanism to avoid mutual influence of operations between workstations; however, for a production line with more workstations, there may be a situation where multiple workstations are stacked at the same time. Even if one of the workstations is no longer stacked, but there are other workstations stacked, the conveying mechanism still must be stopped, seriously affecting production efficiency. Summary of the Invention

[0004] Aiming at the above deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a new structure of an assembly line production equipment, which does not need to stop the conveying mechanism when a workstation is stacked, and realizes non-interference between workstations.

[0005] To solve the above technical problem, the technical solution adopted by the present invention is that a workbench applied to an assembly line production equipment includes a sliding base for sliding on the slide rail of the assembly line production equipment; a fixing part for installing a fixture is provided on the sliding base; and a damping mechanism is further included. The damping mechanism includes a base, a damping component, a rotating shaft and a synchronous wheel. The base is fixedly connected with the sliding base, the damping component is arranged on the base, the transmission shaft is connected with the damping component, and the synchronous wheel is installed on the transmission shaft and is used for meshing with the slide rail of the assembly line production equipment.

[0006] A further technical solution is that the damping component includes a metal ring and two circular permanent magnets; the metal ring is fixedly connected with the transmission shaft; the two circular permanent magnets are fixedly connected with the base; and are respectively located above and below the metal ring; each circular permanent magnet is composed of at least two even-numbered permanent magnets evenly distributed, and the adjacent two permanent magnets have opposite polarities; the circular permanent magnets are overlapped and placed, with the polarities misaligned and the same-polarity permanent magnets overlapping.

[0007] A further technical solution is that the base includes a base plate and a housing covering the base plate; the damping component is placed in the housing; the base plate is provided with a through hole for the transmission shaft to extend out; the transmission shaft extends out below the base plate, and the synchronous wheel is connected to the lower end of the transmission shaft.

[0008] A further technical solution is that the fixing part is located on one side of the sliding base, and the damping mechanism is located on the other side of the sliding base.

[0009] A further technical solution is that it further includes a tension spring. The extending direction of the tension spring is perpendicular to the sliding direction of the sliding base. On the side of the sliding base close to the damping mechanism, there is a notch. One end of the substrate is pivotally connected to the sliding base, the other end of the substrate is connected to the first end of the tension spring, and the second end of the tension spring is connected to the sliding base.

[0010] A further technical solution is that a buffer ejector pin is provided at the end of the sliding base.

[0011] The workbench of the present invention applied to the production line equipment is cooperated with the synchronous pulley through the damping mechanism. During normal transmission, the synchronous pulley does not rotate and is conveyed to the working station by the conveyor belt. When it is fixed at the working station or there is a pile-up, the conveyor belt continues to rotate. When the rotational force is greater than the resistance generated by the damping mechanism, the synchronous pulley rotates without affecting the conveyor belt. Brief Description of the Drawings

[0017] The following further describes the present invention in detail with reference to the drawings and specific embodiments.

[0018] Such as Figure 1As shown in the figure, the workbench of the present invention applied to the pipeline production equipment includes a sliding base 1 that slides on the slide rail (not shown in the figure) of the pipeline production equipment. For the purpose of sliding, the structures such as pulleys and grooves for mating with the slide rail provided on the sliding base 1 are not the technical key points of the present invention and will not be elaborated here. It only needs to be realized that it can slide on the slide rail. The sliding base 1 is provided with a fixing part 11 for installing the fixture 3. According to actual needs, the corresponding fixture 3 is installed to improve the adaptability. It also includes a damping mechanism. The damping mechanism includes a base 21, a damping component, a rotating shaft 22 and a synchronous pulley 23. The base 21 is fixedly connected to the sliding base 1. The damping component is arranged on the base 21. The transmission shaft 22 is connected to the damping component. The synchronous pulley 23 is installed on the transmission shaft and is used to engage with the conveyor belt (not shown in the figure) of the pipeline production equipment. The workbench of the present invention is applicable to the production equipment structure in which the workbench can slide freely on the slide rail and the sliding power is provided by the conveyor belt. It should be noted that the above slide rail, conveyor belt and fixture are not the technical features of the present invention, but only the use environment of the present invention.

[0019] In this embodiment, the damping component is a magnetic torque device, including a metal ring 31 and two circular permanent magnets 32. The metal ring 31 is fixedly connected to the transmission shaft 22. The two circular permanent magnets 32 are fixedly connected to the base 21 and are respectively located above and below the metal ring 31. Each circular permanent magnet 32 is composed of four permanent magnets 32S and 32N evenly distributed (at least two permanent magnets 32S and 32N, and the number is even). The adjacent two permanent magnets 32S and 32N have opposite polarities (the same label indicates the same polarity). The circular permanent magnets 32 are overlapped and placed, with the polarities misaligned and the same-polarity permanent magnets 32 overlapping (that is, there is a misaligned angle between the different magnetic poles), as Figure 2 shown. When the synchronous pulley 23 drives the metal ring 31 to rotate through the transmission shaft 22, the metal ring 31 cuts the magnetic field, and under the action of the magnetic field force, a torque that generates resistance to rotation is generated. By adjusting the angle between the different magnetic poles of the two circular permanent magnets 32 and adjusting the magnetic field distribution, the magnitude of the magnetic torque can be adjusted. The above is only one implementation mode of the present invention. Specifically, the damping can also be realized by conventional damping structures such as torsion springs and springs.

[0020] Specifically, the base 21 includes a base plate 24 and a housing 25 covering the base plate 24. The damping component is placed in the housing 25. The base plate 24 is provided with a through hole for the transmission shaft 22 to extend out. The transmission shaft 22 extends out below the base plate 24, and the synchronous pulley 23 is connected to the lower end of the transmission shaft 22.

[0021] In this embodiment, the fixing part is located on one side of the sliding base, and the damping mechanism is located on the other side of the sliding base. Such a structure facilitates the layout of the production line, enabling the staff or mechanical operating equipment and the conveyor belt to be respectively arranged on both sides of the workbench, making full use of the space.

[0022] Further, as Figure 3 , Figure 4 shown, the present invention further includes a tension spring 12, and the extending direction of the tension spring 12 is perpendicular to the sliding direction of the sliding base 1; on the side of the sliding base 1 close to the damping mechanism, there is a notch 13 for accommodating the synchronous pulley; one end of the substrate 24 is pivotally connected to the sliding base 1 (connected by a pivot shaft 26 in this embodiment), and the other end of the substrate 24 is connected to the first end of the tension spring 12; the second end of the tension spring 12 is connected to the sliding base 1. Such a structure enables the tension spring 12 to apply a force perpendicular to the moving direction of the workbench to the damping mechanism (especially the synchronous pulley 23), making the synchronous pulley 23 closely engage with the tooth surface of the transmission belt.

[0023] Preferably, as Figure 5 shown, a buffer striker 14 is provided at the end of the sliding base 1. When stacking occurs and the next workbench approaches, the buffer striker 14 first buffers to avoid direct collision between the workbenches.

[0024] Working principle: The workbench relies on the conveyor belt to provide power. Since the driving force of the conveyor belt is less than the resistance set by the damping mechanism, after the tooth surface of the conveyor belt meshes with the teeth of the synchronous pulley 23, the synchronous pulley will not rotate, so that the entire workbench slides and translates on the slide rail; when multiple workbenches are stacked due to not entering the working state or the slider mechanism stops due to manual intervention, the workbenches will block each other and cannot move forward. At this time, the torque provided by the conveyor belt to the synchronous pulley 23 will be greater than the torque provided by the damping component. When the two torques oppose each other, the synchronous pulley 23 will rotate; this rotation enables the conveyor belt to continue to move forward while the workbench can stay in place, without affecting the operation of other workstations on the conveyor belt.

[0025] The above is only the preferred embodiment of the present invention. The present invention is not limited to the above embodiment. During the implementation process, various modifications or variations of the present invention that do not depart from the spirit and scope of the present invention and fall within the scope of the claims of the present invention and equivalent technical scope are also intended to be included in the present invention.
