Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a disc-shaped vibration table for self-tapping screws. Background Art

[0002] Generally refers to pointed, coarse-threaded, hard wood screws, but also aluminum alloy and plastic. A special self-tapping screw used to open threads in metal holes is called a tap. Self-tapping screws are used for non-metal or softer metals, without drilling holes and tapping. Self-tapping screws have pointed heads, so they can "self-drill". Ordinary screws are flat-headed and have the same thickness. Self-tapping screws mean that the holes drilled are holes that do not require tapping. The screws used are different from ordinary ones. The head is pointed and the pitch is relatively large. It is a bit like a chipless tap. It can be screwed in directly without tapping. Metals and plastics usually use this method. It can "drill, squeeze, and press" the corresponding threads on the consolidated material by its own threads, so that they fit closely with each other.

[0003] After the production of self-tapping screws is completed, it is necessary to screen and test the self-tapping screws, so as to screen out unqualified self-tapping screws and complete the detection of self-tapping screws, such as a disc-shaped vibration table for self-tapping screws with patent number CN201820201397.4, which includes a mounting plate, and the four corners of the top of the mounting plate are fixedly connected to the bottom of the chassis through electric telescopic rods. A hydraulic press is fixedly installed inside the chassis, and the output end of the hydraulic press is connected to the bottom of the vibration plate through the hydraulic rod. The utility model is provided with an electric telescopic rod, and the height of the device can be adjusted by the electric telescopic rod, so that it can be adjusted according to different users, which is convenient for use; by providing a soundproof cover, the noise generated by the self-tapping screws during the vibration process is isolated, thereby improving the working environment; by providing a spiral discharge pipe and an elbow, large and small self-tapping screws are screened, and unqualified products are discharged to complete the screening.

[0004] However, this structure has the following problems: First, the vibration mechanism of the vibration table uses hydraulic steel to vibrate up and down, which is inefficient and slow; second, it uses a hydraulic system and an electronic control system, a dual system with a complex structure and requires a hydraulic oil tank, which is large in size; third, the hydraulic system is prone to oil leakage, which can easily cause the production environment to become dirty.
