< embodiment one >
As shown in Figure 1, the sealing that the present embodiment provides is described for half tooth tapping screw every electric screw, and sealing is every electric screw with sealing function with every Electricity Functional, and it comprises: screw body and the coating body be coated on screw body.
Concrete, screw body comprises spiral shell head 1 and bar portion, and bar portion has the polished rod 2 of connection spiral shell head 1 and the screw rod 3 away from spiral shell head 1.In the present embodiment, spiral shell head 1 is preferably cross recess coiled hair, and cross recess 11 is opened in the top of spiral shell head 1.
Coating body comprises: be coated in the seal coating 4 on spiral shell head 1 outer side wall, is coated in the locking coating 7 on screw rod 3, and be connected seal coating 4 and locking coating 7 every electric inter coat; Further, seal coating 4, be 12% ~ 18% of polished rod 2 diameter every the coating thickness of electric inter coat and locking coating 7.
Wherein, have every electrocoat 5 and multi-functional coatings 6 every electric inter coat, and, seal coating 4, to be arranged in order every electrocoat 5, multi-functional coatings 6 and locking coating 7 axial direction along screw body.
As preferred technological scheme, the axial length of seal coating 4 equals the axial length of spiral shell head 1, axially extend to the joint of polished rod 2 and screw rod 3 every electrocoat 5 by the edge of seal coating 4, and multi-functional coatings 6 axially extends to locking coating 7 by the joint of polished rod 2 and screw rod 3.In the present embodiment, multi-functional coatings 6 can be worked as and used every electrocoat 5, also can work as locking coating 7 and use.
In the present embodiment, as preferred technological scheme, locking coating 7 is that 60 ° ~ 360 ° circumferences are coated in the outside upper arc ring of screw rod 3 sidewall.
In the present embodiment, seal coating 4, formed by polyamide fiber powder spray every electrocoat 5, multi-functional coatings 6 and locking coating 7.Wherein, polyamide fiber powder is any one or several the combination in poly-omega-amino-undecanoyl, nylon 12, polyamide-6 and polyhexamethylene adipamide.When adopting poly-omega-amino-undecanoyl as spraying raw material, the U.S. can be preferably
the polyamide fiber powder that company produces---
bluePatch.
In addition, the present embodiment additionally provides the manufacture method of a kind of sealing every electric screw, comprises following steps:
Step 1: screw body is heated to 250 DEG C ~ 270 DEG C;
Step 2: the screw body after rotary heating, and adopt tilt angle be the nozzle of 45 ° to the outer surface spraying polyamide fiber powder of screw body to form coating body;
Step 3: the screw body being coated with coating body is cooled 5 ~ 15 seconds to room temperature;
Step 4: screw body is immersed in water soluble anti-rust agent, dries subsequently.
In order to improve the coating efficiency of coating body, in above-mentioned step 2, four nozzles can be adopted respectively simultaneously to screw body spray containment coating 4, every electrocoat 5, multi-functional coatings 6 and locking coating 7.
In the present embodiment, water soluble anti-rust agent is the RustVeto4221 type rust preventing agent produced of Houghton company or RustVeto4222S type rust preventing agent or RustVeto2215B type rust preventing agent or RustVetoMP type rust preventing agent.
As depicted in figs. 1 and 2, the sealing that the present embodiment provides successively axially applies seal coating 4, every electrocoat 5, multi-functional coatings 6 and locking coating 7 every electric screw by spiral shell head 1 to bar portion every electric screw sealing.When using sealing every electric screw, due to the existence of seal coating 4, it has filled up the gap on tapping screw between spiral shell head 1 and territory, non-Electric region 8, therefore the liquid in the external world, dust etc. cannot enter territory, non-Electric region 8, thus forms sealing.Meanwhile, due to the existence every electrocoat 5, it joins on spiral shell head 1 bottom surface at interface and polished rod 2 and defines an isolation layer being positioned at territory, non-Electric region 8 and territory, electric region 9, thus effectively prevents electric current, electrostatic etc. to be leaked into territory, non-Electric region 8 from territory, electric region 9.Finally, due to the existence of multi-functional coatings 6 and locking coating 7 on screw rod 3, it has filled up the gap between screw rod 3 and territory, non-Electric region 8 fully, thus the frictional force enhanced between screw rod 3 and territory, electric region 9, sealing effectively can be prevented every electric screw loosening, be specially adapted to anti-loosening property with every the higher use occasion of requirement on electric performance.
< embodiment two >
In the present embodiment, for identical part in embodiment one, give identical numbering, and omit identical explanation.
As shown in Figure 3, in the present embodiment, be with embodiment one difference: the axial length of seal coating 4 is less than the axial length of spiral shell head 1.As preferred technological scheme, the axial length of seal coating 4 is 30% ~ 80% of spiral shell head 1 length.Namely the outer side wall of polished rod 2, the outer side wall of spiral shell head 1 is coated on and on the step surface that formed between spiral shell head 1 and polished rod 2 every electrocoat 10.
Relative to embodiment one, in the present embodiment, between the outer side wall of the joint of polished rod and screw rod to spiral shell head, define an isolation layer every electrocoat, thus effectively prevent electric current, electrostatic etc. to be leaked into territory, non-Electric region from territory, electric region.Finally, owing to being coated on the multi-functional coatings of screw portion and locking coating, it has filled up the gap between screw rod and territory, electric region fully, and enhances frictional force therebetween, thus effectively prevent screw loosening, be specially adapted to every the higher occasion of electric anti-loosening property requirement.
Certainly, the sealing involved by the utility model is not merely defined in the structure in the present embodiment every electric screw, any equivalent modifications of carrying out the utility model and substituting also all in category of the present utility model.
In embodiment one and embodiment two, seal the spiral shell head every electric screw, certainly, the sealing provided at the utility model is in electric screw, and spiral shell head can also be any one in countersunk head, countersunk raised head, tack.Further, the groove on spiral shell head can also be any one in straight groove, plum blossom groove, interior hex slot, four square grooves, triangular groove, Y shape groove.
