According to the long-axis part with the thread at the end, the mechanical property of long-axis workpieces can be improved, and the service life of the long-axis workpieces can be prolonged. The long-axis part comprises a long-axis part body and further comprises a threaded part. An installation hole is formed in the end of the long-axis part body in the axial direction. The threaded part is installed at the end of the long-axis part body through the installation hole. The machining method comprises the steps that firstly, the long-axis part and the threaded part are machined, and the threaded part installation hole is machined in the end of the long-shaft part; and then the installation hole and the threaded part are cleaned, the interior of the installation hole is coated with an industrial repairing agent, the threaded part is installed in the installation hole, and heating curing is conducted.
Description
Technical field
The present invention relates to a kind of long shaft part, especially relate to the threaded long shaft part of a kind of end belt, belong to mechanical processing technique technical field.The invention still further relates to the processing method of the described long shaft part of a kind of processing.
Background technology
When processing diameter and being greater than the external screw thread on the long-axle workpieces of 80mm, in order to ensure that cutter to exit from thread root and can not damage cutter, on axle, generally need design processing technology escape.Because the diameter dimension at escape place is less than the diameter of thread M that axle is processed, safety coefficient is chosen by calculating the magnitude of load born required for the diameter dimension of axle for general in design, often ignore escape diameter dimension to diminish to the intensity effect of axial workpiece, diametrically the minimizing of effective area and the stress of root R place of escape place generation concentrate two aspects to comprise escape place.Long-axle workpieces is often used for transmitting larger torque and being connected workpiece effect in actual applications, long-axle workpieces can be caused to crack at escape root R place and rupture, therefore have a strong impact on long-axle workpieces mechanical performance, reduce the service life of long-axle workpieces.
Summary of the invention
Technical problem to be solved by this invention is: provide one can effectively improve long-axle workpieces mechanical performance, the threaded long shaft part of the end belt extending its service life.Present invention also offers a kind of processing method for described long shaft part.
For solving the problems of the technologies described above adopted technical scheme be: the threaded long shaft part of a kind of end belt, comprise long shaft part body, described long shaft part also comprises thread part, be provided with installing hole vertically in the end of described long shaft part body, described thread part is arranged on the end of described long shaft part body by described installing hole.
Further, described installing hole is and this body concentric screwed hole of described long shaft part, and described thread part is full thread part, and described full thread part is threaded with described screwed hole by an end.
Further, technique clamping position is respectively arranged with at the two ends of described full thread part.
Further, between described screwed hole and described full thread part, be provided with industrial renovation agent, between described full thread part and described screwed hole by described industrial renovation agent non-removable be connected as a whole.
For processing the processing method of described long shaft part, comprise the following steps,
First process long shaft part body, and clamped one time machines described screwed hole bottom outlet simultaneously, meanwhile adds thread part; Then described screwed hole bottom outlet is processed into screwed hole; Then cleaning screwed hole and thread part need the one end loading described screwed hole, and industrial renovation agent is coated on the inwall of described screwed hole, finally described thread part is cleaned also heating cure in the qualified screwed hole described in the screw-in of end, complete the processing work of a threaded long shaft part of end belt.
Further, when carrying out heating cure to the thread part screwed in described screwed hole and long shaft part body end, described warm temperature is 80 DEG C+5 DEG C, and is incubated 3 hours.
The invention has the beneficial effects as follows: by the thread segment of existing longaxones parts end is improved to independent thread part, and needing one period that screw thread is set and be drilled with concentric threads hole at long shaft part body, then described thread part is installed in described screwed hole by described concentric threads hole, and with industrial renovation agent by heating cure non-removable connect as a whole.Like this, owing to connecting the escape that end does not have diameter less than the diameter of thread at long shaft part, so just do not have the situation of weakening strength to occur at the connection end of long shaft part, the situation generation that stress is concentrated is not had yet, more can not there is stress concentrate and crack and rupture, thus reach effectively raising long-axle workpieces mechanical performance, extend its service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the threaded long shaft part of end belt of the present invention.
Be labeled as in figure: long shaft part body 1, thread part 2, installing hole 3, technique clamping position 4.
Detailed description of the invention
That one provided by the invention can effectively improve long-axle workpieces mechanical performance as shown in Figure 1, the threaded long shaft part of the end belt extending its service life.Described long shaft part comprises long shaft part body 1, described long shaft part also comprises thread part 2, be provided with installing hole 3 vertically in the end of described long shaft part body 1, described thread part 2 is arranged on the end of described long shaft part body 1 by described installing hole 3.And the connection of conveniently thread part 2 and long shaft part body 1, described installing hole 3 is the screwed hole concentric with institute major axis part noumenon 1, described thread part 2 is full thread part, and described full thread part is threaded with described screwed hole by an end.And in order to easy to process, be respectively arranged with technique clamping position 4 at the two ends of described full thread part.Simultaneously, in order to improve the firmness of the connection of thread part 2 and long shaft part body 1 and non-dismountable property, between described screwed hole and described full thread part, be provided with industrial renovation agent, between described full thread part and described screwed hole by described industrial renovation agent non-removable be connected as a whole.
Like this, the step that above-mentioned long shaft part just can be pressed is processed, and first process long shaft part body 1, and clamped one time machines described screwed hole bottom outlet simultaneously, meanwhile adds thread part 2; Then described screwed hole bottom outlet is processed into screwed hole; Then cleaning screwed hole and thread part 2 need the one end loading described screwed hole, and industrial renovation agent is coated on the inwall of described screwed hole, finally described thread part 2 is cleaned also heating cure in the qualified screwed hole described in the screw-in of end, complete the processing work of a threaded long shaft part of end belt.Now, preferred heating cure temperature is that described warm temperature is 80 DEG C+5 DEG C, and is incubated 3 hours when carrying out heating cure to the thread part 2 screwed in described screwed hole and long shaft part body 1 end.
Independent thread part 2 is improved to above by by the thread segment of existing longaxones parts end, and needing one period that screw thread is set and be drilled with concentric threads hole at long shaft part body 1, then described thread part 2 is installed in described screwed hole by described concentric threads hole, and with industrial renovation agent by heating cure non-removable connect as a whole.Like this, owing to connecting the escape that end does not have diameter less than the diameter of thread at long shaft part, so just do not have the situation of weakening strength to occur at the connection end of long shaft part, the situation generation that stress is concentrated is not had yet, more can not there is stress concentrate and crack and rupture, thus reach effectively raising long-axle workpieces mechanical performance, extend its service life.
