Description
Technical field
The invention belongs to machinery and tighten the part field, be specifically related to a kind of quick loading and unloading tappet head that two ends are threaded workpiece of tightening.
Background technology
In industrial circle, need all be threaded two ends and surface requirements tightens on another workpiece than workpiece higher or that profile is more strange sometimes.
Because this type surface of the work requirement height or profile are more strange, be not easy to use the plant equipment clamping.China mainly is to rely on manual the completion to tightening of existing this type workpiece, and this mode production efficiency is low, and labor strength is big.Fig. 1 is the present mode of tightening commonly used to this workpiece.Workpiece one two ends all are threaded, and surfaces externally and internally all is installed nowhere, require in certain torque range, to be screwed to workpiece one on the workpiece two.The first step is screwed to workpiece one on the workpiece two in advance, and second step was put into pad on another end face of workpiece one, and the 3rd step was screwed into spanner Ka Tai on the screw thread of workpiece one an other end, and the 4th step was screwed into bolt in the spanner card platform, made bolt push up pad.After accomplishing above-mentioned steps, be stuck in constant torque wrench on six sides on the spanner Ka Tai, press torque wrench that the workpiece one that is screwed in advance on the workpiece two is tightened by manual work, and reach the requirement torque value.Its Intermediate gasket, bolt, spanner Ka Tai belong to tooling device, and workpiece one takes off spanner after having tightened on the workpiece two on request, unclamps bolt, unloads lower ejector lever Ka Tai, takes pad away, finally accomplishes the work of tightening of this workpiece.
Can to be known by above-mentioned steps, to tighten in order accomplishing that early stage and the follow-up work of doing are a lot, efficient is extremely low; Twist with torque wrench, make workman's work quantitative change many, it is big that working strength becomes.
Summary of the invention
The objective of the invention is to: provide a kind of loading and unloading quick, a kind of quick loading and unloading tappet head that two ends are threaded workpiece of tightening easy to adjust.
Realize that technical scheme of the present invention is: a kind ofly tighten the quick loading and unloading tappet head that two ends are threaded workpiece; It comprises shift fork, thrust ball bearing, end shift fork, end shift fork clamping plate and copper backing; The head of described shift fork is the screw thread column cap; Be inserted with thrust ball bearing in the shift fork, end shift fork is buckled on the thrust ball bearing, and described copper backing is fixed on the end shift fork through screw; Copper backing is stuck in the bottom of screw thread column cap with end shift fork, and the outer of shift fork of the described end is connected with end shift fork clamping plate through fastening bolt.
Have several fixing holes on the shift fork clamping plate of the described end, fastening bolt can be fixed on end shift fork clamping plate on the outer of end shift fork through any 1 fixing hole.
Effect of the present invention is: a kind ofly tighten use that two ends are threaded the quick loading and unloading tappet head of workpiece and simplified and tighten the work set-up procedure that two ends are threaded workpiece; Reached the purpose that Fast Installation two ends are threaded workpiece; Save manpower, improved operating efficiency.

The specific embodiment
A kind ofly tighten the quick loading and unloading tappet head that two ends are threaded workpiece and do further to describe in detail of the present invention below in conjunction with accompanying drawing and specific embodiment.
Like Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5: a kind ofly tighten the quick loading and unloading tappet head that two ends are threaded workpiece; It comprises shift fork 6, thrust ball bearing 7, end shift fork 8, end shift fork clamping plate 9 and copper backing 10; The head of described shift fork 6 is a screw thread column cap 11, and screw thread column cap 11 can be screwed in the respective threaded head in the workpiece 1.
Be inserted with thrust ball bearing 7 in the shift fork 6, end shift fork 8 is buckled on the thrust ball bearing 7, and thrust ball bearing 7 is embedded between shift fork 6 and the end shift fork 8.
Described copper backing 10 is fixed on the end shift fork 8 through 6 screws 14, and copper backing 10 is stuck in the bottom of screw thread column cap 11 with end shift fork 8; The outer of shift fork of the described end 8 is connected with end shift fork clamping plate 9 through fastening bolt 12.
Have several fixing holes 13 on the shift fork clamping plate of the described end 9, fastening bolt 12 can be fixed on end shift fork clamping plate 9 on the outer of end shift fork 8 through any 1 fixing hole 13.
Like Fig. 6 and shown in Figure 7: in use, to workpiece 25, tightening quick loading and unloading tappet head pretension that two ends are threaded workpiece to workpiece 1, stir workpiece one 1 pretensions shift fork 6 and rotate, shift fork 8 rotates at the bottom of shift fork 6 drives.Screw thread column cap 11 on the shift fork 6 further is screwed on the workpiece 1; Pressure between copper backing 10 and workpiece one 1 end faces is increased; Corresponding moment of friction between copper backing 10 and workpiece one 1 end faces is increased, when increasing to moment than 25 of workpiece 1 and workpiece when big, workpiece 1 is screwed to workpiece 25; When the torque ratio copper backing of 25 of workpiece 1 and workpiece when the moment of friction of one 1 of workpiece is big; Shift fork further is tightened onto on the workpiece 1 again, repeats said process, is screwed to workpiece 1 on the workpiece 25 up to moment of torsion on request.
Need from workpiece 1, unload tappet head.Reverse rotation shift fork 6 just can drive end shift fork 8 because of shift fork 6 will rotate to an angle, so end shift fork 8 temporarily can not rotate.The moment that shift fork 6 reverse rotations are overcome is exactly steel ball and bearing race generation moment of rolling friction in shift fork 6 and one 1 screw thread pair moment of frictions of workpiece and the thrust ball bearing 7.
Moment between workpiece 1 and the workpiece 25 is screw thread pair moment of friction and end-face friction moment between the two.Two kinds of torque ratios; Because moment of rolling friction is far smaller than end-face friction moment; So shift fork 6 can rotate by relative workpiece 1; And workpiece 1 not relatively workpiece 25 rotate, thereby unload from workpiece 1 tightening the quick loading and unloading tappet head that two ends are threaded workpiece, and can from workpiece 25, not unload workpiece 1.
End shift fork clamping plate 9 are housed on end shift fork 8, end shift fork clamping plate 9 can through regulate the fixed position, make tighten and when unscrewing shift fork 6 can stir end shift fork 8, realized being quickly installed to workpiece 1 on the workpiece 25, and the purpose that can unload fast.
