Abstract
The utility model discloses a thread protector that is arranged in cylinder body carbonization in -process, including the cylinder, the cylinder is made by the 35CrMo material, the cylinder includes screw thread section and centre gripping section, internal thread hole during the screw thread section is matchd on the cylinder body, the junction of centre gripping section and screw thread section is equipped with the muscle. The utility model discloses a cylinder of integral type structure adopts 35CrMo to make, and difficult the emergence is warp in heat treatment process, the better protection internal thread hole of ability, and the design of muscle can avoid the human error to cause the internal thread to warp or be damaged.
Description
Technical field
The utility model relates to the utility appliance in thermal treatment cementation process, is specifically related to for the thread protector in middle cylinder body carburizing treatment process.
Background technology
The middle cylinder body of existing hydraulic breaking hammer movement is equipped with internal thread hole; and middle cylinder body needs the thermal treatment carburization process carrying out next step after processing internal thread hole; if internal threads hole is not protected; in assembling after carburization process; internal thread hole easily deforms or breakage; cause internal thread unavailable; according to bolt shutoff internal thread hole; because of in the market; the material problem of bolt itself, in heat treatment process, bolt easily deforms or ruptures and then snap in internal thread hole; take out inconvenience, also destructible internal thread.
Summary of the invention
The problem that the utility model easily deforms for the internal thread of the internal thread hole of middle cylinder body in thermal treatment cementation process or destroys; propose a kind of for the thread protector in middle cylinder body carburizing treatment process; this device is cylinder formula structure; 5CrMo material is adopted to make; cylinder is arranged the thread segment matched with the internal thread hole on middle cylinder body, thus play the object of protection internal thread hole.
For solving the problems of the technologies described above; the technical scheme that the utility model adopts is: for the thread protector in middle cylinder body carburizing treatment process; comprise cylinder; described cylinder is made up of 35CrMo; described cylinder comprises thread segment and gripping section; internal thread hole in thread segment coupling on cylinder body, the junction of described gripping section and thread segment is provided with muscle.
Wherein, thread segment, gripping section, muscle are integral type structure.
In a preferred embodiment of the present utility model, described gripping section is flat part.
The beneficial effects of the utility model are: the cylinder of integral structure adopts 35CrMo to make; not easily deform in heat treatment process; internal thread hole and long service life can better be protected; from the angle of life-time service; be conducive to cost-saving, the design of muscle can avoid human error to cause internal thread to be out of shape or breakage.

Fig. 2 is vertical view of the present utility model;
Fig. 3 is left view of the present utility model.
Embodiment
Below in conjunction with embodiment, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 to Figure 3, for the thread protector in middle cylinder body carburizing treatment process, comprise cylinder, cylinder is made up of 35CrMo, and this material is high temperature resistant, at high temperature not easily deforms, and fracture and long service life do not occur; Described cylinder comprises thread segment 1 and gripping section 3, internal thread hole during thread segment 1 mates on cylinder body, gripping section 3 is flat part, gripping section 3 adopts flat part to design, and takes out cylinder after being convenient to carburizing treatment, and the junction of gripping section 3 and thread segment 1 is provided with muscle 2, when muscle 2 can prevent the internal thread hole of cylinder body in cylinder precession, screwed in dark, affected the shutoff of internal thread hole upper end, and caused internal thread to be out of shape or breakage.
For a person skilled in the art; still can the technical scheme described in foregoing embodiments be modified; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
