Abstract

The invention discloses a power-tongs spinning component and a processing method thereof. The power-tongs spinning component comprises a jaw plate and a tooth plate, and is characterized in that the tooth plate is an arc knurled tooth plate, a plurality of groups of symmetrical long arc straight teeth and pyramid teeth which are crossed with an arc triangular groove, the teeth face towards the circle center of the arc surface; the arc knurled tooth plate is mounted in a dovetail groove of the jaw plate and overlaid and limited by a screw; a Z-shaped opening spring ring is mounted in an annular groove of a cylindrical head with a screw inside, so that the screw has the elastic limit action; two staggered half openings which are communicated in the middles are arranged on the two side surfaces of the Z-shaped opening spring ring, so that the spring ring is the whole circle and also has the elastically telescoping Z-shaped opening. The spinning component is reasonable in structure, reliable and durable in performance, the processing technology of the arc Z-shaped opening spring ring is simple and effective; and the work quality and economic benefic of oil drilling operation using power tongs are effectively improved.

Description

Power Tong spinner parts and processing method
Technical field
The present invention relates to a kind of Power Tong spinner parts and processing method.
Background technology
Petroleum drilling and mining Power Tong " is bitten " the tubular pillar drilling tool rotaries such as drilling rod, sleeve pipe, oil pipe by the dental lamina on jaw and has been transferred and unload spinner operation, dental lamina and jaw carrying moment very large, therefore the contact surface of dental lamina and tubular pillar drilling tool is the bigger the better.But the spinner parts one of existing various Power Tong adopt the spacing plane teeth of end face to parallel short dental lamina, and the contact area of clamping drilling tool is little, clamping is easily skidded damage drilling tool, dental lamina damage easy to wear; Two is adopt the spacing long teeth plate in screw side, and contact area increases, good clamping effect, but starting the moment impact force that produces of dental lamina at spinner easily weighs wounded and even damage stop screw.These two kinds of structures all directly affect the work quality economic benefit of drillng operation.
We attempt being used in installation shaft opening elastic ring on stop screw, and extenuate the impact force of dental lamina, screw does not damage, but just inoperative when dental lamina application point is in elastic ring aperture position.During spinner operation, dental lamina produces radial load to elastic ring, and the flexible opening of elastic ring must have, but how to avoid dental lamina application point be a great problem.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, durable, the Power Tong spinner parts of processing technology simple and effective and processing method.
Technical solution of the present invention is:
A kind of Power Tong spinner parts, comprise jaw, dental lamina, it is characterized in that: described dental lamina is cambered surface flower teeth plates, dental lamina cambered surface is provided with long arc straight-tooth and rectangular pyramid tooth that array Symmetrical Circular Arc triangular groove intersects synthesis, the teeth directional cambered surface center of circle; Cambered surface flower teeth plate is contained in jaw dovetail groove, and spacing with the screw junction of the edges of two sheets of paper; The turn of Z-type opening is installed in the cannelure of the socket cap of mounting screw, makes screw have elastic spacing effect; What the two sides of the turn of Z-type opening arranged that centre communicates two to stagger half opening, makes turn be full circle flexible flexible Z-type opening again.
A kind of processing method of Power Tong spinner parts, it is characterized in that: clamping cutterhead on lathe chuck, the different-diameter of cutterhead is circumferentially installed several cutter, the fixing dovetail pressing plate that mounting clamp is concrete on lathe carriage and movable dovetail pressing plate, in movable dovetail pressing plate, dental lamina base is set, pull handle drive activity dovetail platen clamp or unclamp dental lamina base and load and unload, rotating cutter-head and displacement planker, carry out the processing of cambered surface flower teeth plate; With spring steel bar spring winding base on the axle of lathe, spring base cuts off opening, processing openend two symmetry lacks limit, and shaping after-baking, completes the processing of Z-type split circlip; Again the cambered surface processed flower teeth plate, Z-type split circlip and jaw are assembled, spacing with the screw junction of the edges of two sheets of paper.
Spinner modular construction of the present invention is reasonable, and dependable performance is durable, cambered surface Z-type split circlip processing technology simple and effective; Effectively improve work quality and the economic benefit of the operation of Power Tong petroleum drilling and mining.
