Description

Technical Field

[0001] The present application relates to the technical field of slender rod processing, and in particular to a stabilizing device for axial progressive rotation processing of slender rods. Background Art

[0002] Slender rods are typical mechanical parts, characterized by their length being much greater than their diameter. The processing method includes using a horizontal lathe, inserting the rod into the lathe shell from the outside, and then passing it out of the lathe chuck to the processing length (see the instructions attached). Figure 1-3 As shown in the figure, after the chuck clamps the rod and drives the rod to rotate, the tool can be used to process the part of the rod extending out of the chuck. For example, when processing a bolt, after the external thread of the rod is processed, a cutting tool is used to cut it off, and the rod is pushed forward to move, so that continuous processing operations of the bolt can be carried out.

[0003] As the instruction manual Figure 1 As shown in the figure, in the initial stage of processing the slender rod, most of it is located outside the machine tool housing and is in a suspended state. It will bend downward due to its own gravity. At the same time, when driven by the rotation of the chuck, the suspended rod body will form a large circumferential swing amplitude, as shown in the figure. Figure 4 As shown, under the rotational swinging inertia, the suspended slender rod will have bending and breaking problems, and the bent rod part will affect the processing quality of the thread during subsequent processing, and the broken rod will have a great safety hazard under the rotational inertia. Summary of the invention

[0004] In response to the above-mentioned problems, the present application aims to provide a stabilizing device for the axial progressive rotation processing of slender rods, which can effectively limit and reduce the swing range of the rods, thereby solving the problems of bending and breaking of the currently suspended rods during the rotation process, thereby improving the processing quality of the rods and reducing safety hazards during processing.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: a stabilizing device for axial progressive rotation processing of a slender rod, wherein the rod is rotationally clamped on a machine tool chuck and extends to the outside of the machine tool shell, and is characterized in that: the stabilizing device is arranged on the outside of the shell and limits and reduces the swing range of the rod in a rotating state.

[0006] Preferably, the stabilizing device is a stabilizing cylinder which is coaxially arranged with the rod on the outside of the shell and circumferentially covers the rod, and support rods are arranged at intervals on the bottom side of the stabilizing cylinder.

[0007] Preferably, the stabilizing tube is configured as a bell-mouth structure with an inner diameter gradually increasing away from the shell.

[0008] Preferably, a rotating ring capable of contacting the rod is arranged on the inner wall of the stabilizing cylinder along an axial interval.

[0009] Preferably, a flexible pad is circumferentially arranged on the inner wall of each rotating ring.

[0010] The beneficial effect of the present application is that the stabilizing device (stabilizing cylinder) is set up, which, after being put on the rod, can effectively limit and reduce the swing range of the rod when the rod is rotating, thereby solving the problem of bending and breaking of the currently suspended rod during the rotation process, thereby improving the processing quality of the rod and reducing safety hazards during processing.

[0022] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See attached Figures 1 to 11 A stabilizing device for axial progressive rotational processing of a slender rod is shown, wherein the rod 1 is rotatably clamped on a machine tool chuck 2, and the rod 1 extends to the outside of a shell 3 of the machine tool. During the process of driving the rod 1 to rotate by the machine tool chuck 2, the portion of the rod 1 extending to the shell 3 has a large circumferential rotational deflection. In order to solve the problem that the deflection easily causes the rod 1 to bend or break, the present application is designed with a stabilizing device, which is arranged on the outside of the shell 3 and limits and reduces the swing range of the rod 1 in a rotating state. After limiting and reducing the swing range of the rod 1, the problem of bending and breaking of the rod 1 during rotation can be solved, thereby improving the processing quality of the rod 1 and reducing safety hazards during processing.

[0024] Specifically, Figure 5-7 As shown, the stabilizing device is a stabilizing cylinder 4 which is coaxially arranged with the rod 1 on the outside of the housing 3 and circumferentially covers the rod 1, and a support rod 5 is arranged at intervals on the bottom side of the stabilizing cylinder 4. One end of the stabilizing cylinder 4 can be welded to the housing, and the stabilizing cylinder 4 is stably supported from the ground by the support rod 5. When in use, the rod 1 is inserted into the stabilizing cylinder 4 and clamped at the machine tool chuck 2. When the rod is driven to rotate, the rotation and swing of the rod 1 is limited in the stabilizing cylinder 4, thereby effectively limiting and reducing the swing amplitude of the rod 1, solving the problem that the rod 1 is easy to bend or break in the suspended state.

[0025] During the rotation of the rod 1, its swing amplitude gradually increases in the direction away from the chuck ( Figure 4 The tail end of the machine is too large to rotate and swing, and after contacting the inner wall of the stabilizing tube 4, a large contact impact is formed, which not only affects the surface quality of the rod to be processed, but also causes a large processing noise. Therefore, in order to solve this problem, Figure 5-6 As shown, the stabilizing cylinder 4 is configured as a bell-mouth structure with an inner diameter gradually increasing away from the shell 3. This structure is adapted to limit the swing amplitude at different positions of the rod, so that the swing amplitude of the rod can be adaptively and gradually reduced along the axial direction to solve the problem of large impact contact between the rod and the inner wall of the stabilizing cylinder 4, which affects the surface quality of the rod and causes large impact noise.

[0026] Since the rod 1 is in a rotational driving state during the processing, the swing amplitude of the stabilizing cylinder 4 is reduced during its rotation, so that the rod will rotate in contact with and rub against the inner wall of the stabilizing cylinder 4, which is easy to cause surface friction and wear of the rod 1 during continuous rotation. Therefore, in order to solve this problem, Figure 8-10As shown, a rotating ring 6 that can contact the rod 1 is arranged along the axial spacing on the inner wall of the stabilizing cylinder 4. The rotating ring 6 is preferably a bearing, the outer ring of which is fixed to the inner wall of the stabilizing cylinder 4, and the inner ring is in contact with the rotating and swinging rod. Therefore, when the rod swings and contacts the inner ring of the rotating ring 6, it can rotate and contact with the inner ring, thereby reducing the problem of rotational friction and wear between the rod 1 and the inner wall of the stabilizing cylinder 4, and further ensuring the surface quality of the rod 1.

[0027] In order to further reduce the swing impact of the rod 1, Fig.11 As shown, a flexible pad 7 is circumferentially arranged on the inner wall of each rotating ring 6. After the rod 1 contacts the flexible pad 7, the swing impact of the rod 1 can be reduced through the flexible effect, thereby effectively protecting the rod 1 and reducing the impact noise.

[0028] The principle of the present application is: a stabilizing cylinder 4 is arranged outside the machine tool housing 3 to circumferentially wrap the rod 1, and the stabilizing cylinder 4 is stably supported from the ground by a supporting rod 5. When in use, the rod 1 is inserted into the rotating ring 6 in the stabilizing cylinder 4 and clamped at the machine tool chuck 2. When the rod is driven to rotate, the rotation and swing of the rod 1 is restricted in the stabilizing cylinder 4. At the same time, the rotation and swing of the rod 1 are synchronized after contacting the rotating ring 6, and the swing impact is reduced by contact between the rod 1 and the flexible pad 7, thereby ensuring the quality of the rod and reducing processing noise.

[0029] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
