Abstract
The utility model provides a tooth form appliance. The tooth form appliance comprises an extruding shaft, a clamp spring and an expansion-shrink sleeve, wherein the extruding shaft is a cylindrical body, the lower portion of the extruding shaft is provided with taper, the clamp spring is a round ring with an opening, the expansion-shrink sleeve is a cylindrical body with an opening, the outer side of the expansion-shrink sleeve is provided with rectifying threads, the upper portion of the expansion-shrink sleeve is provided with a clamp groove, the part, provided with the taper, of the extruding shaft is inserted into the cylindrical expansion-shrink sleeve, the clamp spring is clamped inside the clamp groove of the expansion-shrink sleeve, the extruding shaft is clamped inside the expansion-shrink sleeve, the extruding shaft comprises a handle and a tapered rod, the cross section of the handle is a hexagon, and the cross section of the tapered rod is round. The tooth form appliance is a tool composed of an extruding tapered shaft, the extruding shaft and the expansion-shrink sleeve. After the expansion-shrink sleeve is screwed into a connector, a damaged threaded tooth form is rectified by means of an expansion-shrink function of the expansion-shrink sleeve with threads, production of aluminum chips is avoided, influences on the inside of a core body are avoided.
Description
Technical field
The utility model relates to a kind of thread form rectifier, a kind of device that defective ridge is proofreaied and correct.
Background technology
Heat exchanger aluminum joint screw thread in use because pressure, collision, a lot of reasons such as be heated causes the profile of tooth of screw thread to be damaged and is out of shape, and jiont treatment and sealing property are affected, product can't use.Repair with the screw tap hard waste, but can produce the aluminium bits, fall into heat exchanger cavity.And heat exchanger cavity can not have the aluminium bits.Therefore need a kind of special tool(s) to come the joint screw thread profile of tooth of damaging is corrected.This utility patent is based on this designed a kind of thread form rectifier.
The utility model content
In order to overcome above problem, the utility model provides a kind of thread form rectifier, after the joint screw thread tooth form is damaged, uses this structure tool, can carry out the chipless rectification by the butt joint screw thread, and is simple to operation quick.
For solving above technical problem, the technical scheme that the utility model provides is as follows: rectifier comprises extrusion axis, jump ring and harmomegathus cover, and extrusion axis is column, and its underpart has tapering; Jump ring is the annulus with opening; The harmomegathus cover is for having opening and outside cylindrical body with correction screw thread, and top has draw-in groove; Extrusion axis has the harmomegathus cover of the partial insertion tubular of tapering, and jump ring is stuck in the draw-in groove of harmomegathus cover, and extrusion axis is stuck in the harmomegathus cover.
Further, described extrusion axis comprises handle and tapered rod, and handle is that cross section is hexagon, and the cross section of tapered rod is circular.
Further, the outer top with correction screw thread of described harmomegathus cover has a step, and this step place is provided with retainer ring.
Further, the symmetrical part of described jump ring upper shed place has circuitous shell fragment, and this circuitous shell fragment has makes jump ring have stronger elastic force effect.
Further, the vertical range of described jump ring opening is 1mm.
Further, the vertical range of described harmomegathus cover opening is 1mm.
This thread form rectifier that the utility model relates to overlaps the instrument that forms by the extruding axis of cone, extrusion axis and harmomegathus.Behind harmomegathus cover screw-in joint, utilize the harmomegathus function of threaded expansion sleeve that the form of thread of damaging is corrected, can not produce the aluminium bits, core body inside is not exerted an influence.

The specific embodiment
Shown in Fig. 1-4, rectifier comprises extrusion axis 1, jump ring 2 and harmomegathus cover 4, and extrusion axis 1 is column, comprises handle 11 and tapered rod 12, and handle 11 is hexagon for cross section, and the cross section of tapered rod 12 is circular.Jump ring 2 is for having the annulus of opening; Harmomegathus cover 4 is for having opening 41 and outside cylindrical body with correction screw thread, and top has draw-in groove; Extrusion axis 1 has the harmomegathus cover 4 of the partial insertion tubular of tapering, and jump ring 2 is stuck in the draw-in groove of harmomegathus cover 4, and extrusion axis 1 is stuck in the harmomegathus cover 4.
Harmomegathus cover 4 outer tops with correction screw thread have a step, and this step place is provided with retainer ring 3.Acting as a whole set of rectifier of retainer ring is accurately fixing, and after accurately fixing, the thread form of the ridge of its correction is only accurately, and is standard compliant or design.
The symmetrical part of jump ring 2 upper sheds 22 has circuitous shell fragment 21, and this circuitous shell fragment 21 has makes jump ring 2 have stronger elastic force effect.
The vertical range of jump ring 2 openings 22 is 1mm.
The vertical range that harmomegathus is overlapped 4 openings 41 is 1mm.
This thread form rectifier that the utility model provides is fixed on extrusion axis 1 on the harmomegathus cover 4 with jump ring 2, with control harmomegathus amount size.During use, harmomegathus cover 4 is screwed in the joint screw thread, with extrusion axis 1 spreading harmomegathus cover 4, the thread form that has damaged in the double thread is corrected.Owing to being that coaxial radially spreading is corrected, therefore can not produce the aluminium bits, can not pollute core body inside again yet.
The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
