Description

Technical Field

[0001] The invention relates to a semi-automatic rubber ring fitting mechanism. Background Art

[0002] In the field of mechanical processing, rubber rings are used as seals or fixings and often need to be put on other parts. In the existing technology, workers generally operate them manually, which is inefficient and often has problems with inaccurate positioning. In addition, workers' hands are prone to pain after long-term operation. Summary of the Invention

[0003] The object to be achieved by the present invention is to provide a semi-automatic rubber ring fitting mechanism, which can realize the automatic operation of the rubber ring and improve the production efficiency.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a semi-automatic rubber ring mechanism, including a frame, the frame including a first lifting platform, a second lifting platform, a third lifting platform and a rubber ring expansion assembly, the frame is provided with a first lifting drive connected to the first lifting platform, the first lifting platform is provided with a second lifting drive connected to the second lifting platform, the bottom end of the rubber ring expansion assembly is connected to the second lifting platform, the top end of the rubber ring expansion assembly is connected to the third lifting platform, the rise and fall of the second lifting platform controls the rubber ring expansion assembly to expand or tighten the rubber ring, the workpiece clamping assembly is arranged at the top of the frame, and the frame is also provided with a clamping assembly for pressing the rubber ring onto the workpiece.

[0005] When in use, place the rubber ring on the rubber ring expansion assembly, start the second lifting drive, the second lifting drive moves upward to drive the second lifting platform to rise, the second lifting platform rises to drive the rubber ring expansion assembly, the rubber ring expansion assembly expands the rubber ring, now put the workpiece in, start the second lifting drive again to move downward to the set distance, at this time the second lifting platform descends to drive the rubber ring expansion assembly to tighten, so that the rubber ring shrinks toward the workpiece, at this time the rubber ring can just be reduced to a position that fits the workpiece, at this time start the workpiece clamping assembly to clamp the workpiece and the rubber ring, and perform a tightening operation on the rubber ring to make the fitting effect of the rubber ring better, thereafter by starting the first lifting drive to descend, drive the first lifting platform, the first lifting platform drives the second lifting platform to descend, and the second lifting platform pulls the rubber ring expansion assembly This drives the third lifting platform to descend, thereby separating the rubber ring expansion component from the rubber ring, and thus removing the workpiece completes the rubber ring operation of the workpiece. After resetting all mechanisms, the operation can be repeated for continuous processing. During the entire process, workers only need to manually place the rubber ring and workpiece and remove the finished product, which effectively solves the problems of low efficiency, inaccurate positioning and easy pain in workers' hands in the existing technology. Moreover, a fully automated rubber ring putting device can be composed of an automatic rubber ring putting device and an automatic workpiece picking and placing device, which has good scalability and the execution speed of all driving parts is faster than the manual speed. Therefore, the entire rubber ring putting process is very short and the production efficiency is high. No manual operation is required during the rubber ring putting process, and manual operation is only required when the mechanism stops, which can effectively ensure the personal safety of workers.

[0006] Preferably, the rubber ring expansion assembly includes a fixed block and a profiling block, the fixed block is detachably mounted on the second lifting platform, the profiling block is movably connected to the third lifting platform, the frame is provided with a sliding hole connected to the profiling block, the profiling block is provided with a stretching step, a movable connecting rod is provided between the fixed block and the profiling block, and the rubber ring is pulled by stretching the step. When the second lifting platform rises, the movable connecting rod drives the profiling block to slide outward on the third lifting platform. At this time, the rubber ring is stretched, and the workpiece can be placed in it, and the profiling block will not contact the workpiece at this time. When the second lifting platform descends, it will first drive the movable connecting rod, and the movable connecting rod drives the profiling block to slide toward the workpiece, so that the rubber ring fits the workpiece. The structure is ingenious and compact, and compared with the existing tensile structure set on all sides, it occupies less space.

[0007] Preferably, the third lifting platform is provided with a plurality of sliding mounting blocks for mounting the profiling blocks, and a slide groove for the profiling block to slide is formed between two adjacent sliding mounting blocks. The profiling block can be installed behind the two sliding mounting blocks, and the sliding mounting block can be fixed to the third lifting platform. The assembly is convenient, and compared with the structure of directly processing the slide groove on the third lifting platform, the processing difficulty of the third lifting platform can be effectively reduced.

[0008] Preferably, the pressing assembly includes a fixed seat, an arc clamping block slidably connected to the fixed seat, a transmission disc arranged above the arc clamping block, and a pressing driving member arranged on the frame and connected to the transmission disc, the transmission disc is provided with a sliding groove corresponding to the arc clamping block, and the arc clamping block is provided with a sliding member that cooperates with the sliding groove, and the transmission disc is driven by the pressing driving member to rotate a certain angle. Under the influence of the extrusion force of the transmission disc, the sliding member will slide in the sliding groove, so that the arc clamping block will slide toward the workpiece direction to clamp the rubber ring and the workpiece. The structure is clever. Compared with the traditional structure that directly drives the transmission disc by the motor, this structure does not need to consider the way the motor is set, reduces the design cost, and has a greater driving force, which is convenient for controlling the rotation angle of the transmission disc. The arc clamping block is just between the intervals of the profiling block and will not interfere with the profiling block.

[0009] Preferably, the sliding groove is obliquely arranged on the transmission disc, and the inclination direction of the sliding groove is exactly the sliding direction of the sliding member when the transmission disc rotates, so that the arc-shaped clamping block will inevitably move toward the workpiece.

[0010] Preferably, the transmission disc is evenly provided with a plurality of radial limit assemblies in the circumferential direction, which can avoid bending during long-term use. Because the rotating shaft often needs to receive radial load force, this setting has a greater ability to withstand radial load force.

[0011] Preferably, the outer ring of the transmission disc is provided with an arc groove, and the radial limiting assembly includes a support block detachably mounted on the frame, and a roller provided on the support block, and the roller abuts against the arc groove. Under the premise of not hindering the rotation of the transmission disc, the transmission disc can be suspended in the air, eliminating the use of a support shaft and the need to consider the problem of avoiding other parts when setting the support shaft, thereby reducing design costs and having better radial load capacity.

[0012] Preferably, a limit drive is provided on the first lifting platform, which limits and adjusts the descending distance of the second lifting platform through the limit drive, thereby controlling the descending stroke of the second lifting drive. The control is convenient. Compared with the structure using sensors, this setting can play a supporting role for the second lifting platform, thereby reducing the burden on the second lifting drive after the second lifting platform descends.

[0013] Preferably, a first guide rod is provided on the frame, and the first lifting platform and the third lifting platform are provided on the first guide rod. The first guide rod can facilitate the lifting of the first lifting platform and the third lifting platform, reduce friction, and reduce the burden on the driving parts.

[0014] Preferably, a second guide rod is provided between the first lifting platform and the third lifting platform, and the second lifting platform is provided on the second guide rod. The first lifting platform can support and connect the third lifting platform through the second guide rod, so that when the first lifting drive member drives the first lifting platform to descend, the burden of the rubber ring expansion assembly can be reduced.

[0015] In summary, the advantages of the present invention are as follows: the expansion or tightening of the rubber ring of the rubber ring expansion assembly is controlled by the second lifting drive member, and the rubber ring is pressed against the workpiece by the pressing assembly, which can achieve a better fitting effect of the rubber ring. Then, the first lifting drive member controls the lifting and lowering of the first lifting platform, the first lifting platform drives the second lifting platform to descend, and the second lifting platform pulls the rubber ring expansion assembly, thereby driving the third lifting platform to descend, thereby separating the rubber ring expansion assembly from the rubber ring. In this way, the workpiece is removed to complete the rubber ring operation of the workpiece. After all mechanisms are reset, the operation can be repeated to achieve continuous processing. During the entire process, only the worker needs to manually place the rubber ring and the workpiece and remove the finished product, which effectively solves the problems of low efficiency, inaccurate positioning and easy pain of the worker's hands in the prior art. In addition, the fully automated rubber ring equipment can be composed of an automatic rubber ring placing device and an automatic workpiece picking and placing device, which has good scalability and the execution speed of all driving components is faster than manual speed. Therefore, the entire rubber ring process is very short and the production efficiency is high. No manual operation is required during the rubber ring process, and manual operation is only required when the mechanism stops, which can effectively ensure the personal safety of the worker.

In this way, the workpiece is removed to complete the rubber ring operation of the workpiece. After resetting all mechanisms, the operation can be repeated for continuous processing. During the whole process, workers only need to manually put on the rubber ring and workpiece and remove the finished product, which effectively solves the problems of low efficiency, inaccurate positioning and easy pain in workers' hands in the existing technology. Moreover, a fully automated rubber ring putting device can be formed by automatic rubber ring placing equipment and automatic workpiece picking and placing equipment, which has good scalability and the execution speed of all driving parts is faster than manual speed. Therefore, the whole rubber ring putting process is very short and the production efficiency is high. No manual operation is required during the rubber ring putting process.

At this time, the rubber ring is stretched and the workpiece can be placed in it. At this time, the profiling block 62 will not contact the workpiece. When the second lifting platform 3 descends, the movable connecting rod 63 will be driven first, and the movable connecting rod 63 drives the profiling block 62 to slide toward the workpiece, so that the rubber ring fits the workpiece.

[0030] The sliding groove 731 is set obliquely on the transmission disc 73. The inclined direction of the sliding groove 731 is just the sliding direction of the sliding member 74 when the transmission disc 73 rotates, so that the arc clamping block 72 will inevitably move toward the workpiece direction. The transmission disc 73 is evenly provided with a plurality of radial limit assemblies in the circumferential direction, which can avoid the bending caused by long-term use of rotation.
