Description
Technical field
The present invention relates to a kind of screw assembling device, relate in particular to a kind of screw assembling device with displacement transducer.
Background technology
Screw is widely used in the modern project mechanical work, better brings into play its effectiveness in order to make screw, and spring washer and plain washer almost become the important component that screw is installed.Usually, the position of spring washer does not contact with part in the centre of screw nut and plain washer, and its effect is: utilize the resilient characteristic of self material, peristome is support screw head and plain washer respectively, is difficult for loosening during use and comes off.The position of plain washer contacts with spring washer and connected piece after installing below spring washer, and its effect is: increase the contact area with connected piece 1.; 2. the pressure on the discrete units area; 3. prevent from being connected the workpiece scratch.
In general, in the screw installation process, spring washer and plain washer can be used in combination, but also have some occasion only to need plain washer to get final product.And no matter be spring washer or plain washer, before screw is installed, all must in advance its screw rod from screw be inserted on the nut of screw.This process manually-operated is not only wasted time and energy, inefficiency, and processing safety is much lower, is easy to occur the scratch accident.
In view of this, existing Screw gasket normally is pressed on the screw by mechanical device automatically, see also shown in Figure 1, existing automatic press-fit equipment 9 comprises pedestal 90, hollow pressure head 91, limit for height screw 92, its hollow core pressure head 91 is hollow tube, and its hollow space can pass for the screw rod of screw 93 just, and the hollow tube end then can closely be pressed against packing ring 94 on the nut of screw, thereby finishes the prepackage of screw assembly.
Yet, the shortcoming of described automatic press-fit equipment is apparent: owing to adopt limit for height screw 92 to limit the height that screw is pressed into, after the multiple-contact wearing and tearing, the length of limit for height screw 92 self may change, also rough phenomenon may because of wearing and tearing appear with limit for height screw 92 contacted platforms simultaneously, so all, all will affect the precision that packing ring is pressed into screw, even the consequence that packing ring is damaged by pressure can occur.
Therefore, how to design a kind of automatic assembly equipment, it not only successfully is pressed into screw with packing ring, more can guarantee the precision that it is pressed into, and has just become problem anxious to be resolved.
Summary of the invention
