[0002] There are various special-shaped structural parts in an automobile exhaust system, for example, a part adapter.

DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are only intended to explain the present application and not to limit the present application.

[0035] Please refer to Figures 1 to 4 , now the special-shaped automobile part lathe conversion tool provided by the present application will be described. The special-shaped automobile part lathe conversion tool comprises a fixing frame 1, an inclined plate 3, a positioning disc 4, a stop block 5 and a fixing mechanism 6. One side of the fixing frame 1 is fixedly provided with a fixing disc 2 for mounting to a lathe; the inclined plate 3 is fixedly mounted on the fixing frame 1 and is arranged obliquely on the fixing frame 1 from top to bottom along the axis of the fixing disc 2; the positioning disc 4 is fixedly mounted on the inclined plate 3 and is in sliding fit with the inner hole of one end of the structural member; the stop block 5 is fixedly mounted on the inclined plate 3 and is located on one side of the positioning disc 4 for limiting the one-way rotation of the structural member on the positioning disc 4; the fixing mechanism 6 is mounted on the inclined plate 3 for fixing the structural member to the inclined plate 3.

[0036] The special-shaped automobile part lathe conversion tool provided by the present embodiment has the following advantages compared with the prior art. The fixing frame 1 is provided, and the fixing disc 2 and the inclined plate 3 are respectively mounted on the opposite sides of the fixing frame 1. The included angle between the inclined plate 3 and the axis of the fixing disc 2 is the same as the included angle between the structural member and the axis of the inner hole of the two ends of the structural member. The position of the positioning disc 4 on the inclined plate 3 is designed according to the size of the structural member. After the structural member is mounted on the inclined plate 3, the position of the structural member on the positioning disc 4 is adjusted, so that the axis of the hole to be machined of the structural member coincides with the axis of the fixing disc 2, and when the axis of the hole to be machined coincides with the axis of the fixing disc 2, the outer side surface of the structural member abuts against the stop block 5. Therefore, when the fixing disc 2 is clamped to the numerical control lathe, the axis of the hole to be machined of the structural member coincides with the axis of the numerical control lathe. In the present application, one end of the structural member is sleeved on the fixing disc 2, and the structural member is rotated with the axis of the fixing disc 2 as the center until the structural member abuts against the stop block 5. Then the fixing mechanism 6 is used to fix the structural member to the inclined plate 3, and the machine tool is started to machine the hole to be machined of the structural member. During the machining process, the tool can realize the quick clamping and alignment of the structural member, and the inclined plate 3 and the positioning disc 4 can convert the special-shaped structural member into a lathe machining, thereby effectively improving the machining efficiency of the special-shaped structural member.

[0037] Specifically, in the present embodiment, the stop block 5 is fixedly mounted on the inclined plate 3 by bolts, and a pin is further arranged between the stop block 5 and the inclined plate 3 for positioning the relative position of the stop block 5 and the inclined plate 3.

[0038] In some embodiments, the stop block 5 can adopt the structure as shown in Figure 2 . Referring to Figure 2The positioning pin 51 is threadedly connected to the stopper 5 and is used to abut against the outer side wall of the structural member. The fixing member 52 is also threadedly connected to the positioning pin 51 and is used to abut against the stopper 5. The positioning pin 51 is threadedly connected to the stopper 5 and the length direction of the positioning pin 51 is along the tangent direction of the positioning disc 4. Since the two ends of the structural member are not on the same axis, when one end of the structural member is rotated on the positioning disc 4, the outer side wall of the structural member abuts against the end of the positioning pin 51. When the outer side wall of the structural member abuts against the end of the positioning pin 51, the axis of the hole to be machined of the structural member coincides with the axis of the fixing disc 2. Thus, the position accuracy of the later machining is ensured.

[0039] Preferably, in the embodiment, the positioning pin 51 is threadedly connected to the stopper 5, so that the position of the positioning pin 51 can be adjusted, and the machining position of the structural member can be adjusted. After the adjustment is completed, the fixing member 52 is used to abut against the stopper 5 to fix the position of the positioning pin 51. In the later part machining, the structural member can be positioned by mounting one end of the structural member to the positioning disc 4 and rotating the structural member, so that the outer side wall of the structural member abuts against the end of the positioning pin 51. The quick alignment and positioning clamping can be realized, and the method is suitable for batch machining of structural members. The machining efficiency in batch machining process is effectively improved.

[0040] Specifically, in the embodiment, after the first structural member is mounted to the positioning disc 4 and abuts against the end of the positioning pin 51, the position of the structural member is detected, the position of the positioning pin 51 is adjusted to assist the adjustment of the angle of the structural member, and finally the hole to be machined of the structural member is coaxial with the fixing disc 2. Then, the positioning pin 51 is fixed to the stopper 5 by the fixing member 52. The later machined structural members can be aligned and positioned by the positioning pin 51, the time for later alignment and positioning is saved, and the machining efficiency is improved.

In the actual application process, the hydraulic chuck on the numerical control lathe is disassembled, then the fixed disc 2 is installed at the position corresponding to the hydraulic chuck, and the pull rod 641 is connected to the hydraulic cylinder for driving the hydraulic chuck. Therefore, the original control program of the machine tool can be used to control the clamping and dismounting of the structural part, without additional new air cylinder and control module.

[0045] In some embodiments, the above-mentioned transmission assembly can adopt the structure as shown in Figure 3 . Referring toFigure 3 The transmission assembly comprises a swing rod 642 and a transmission rod 643.

The transmission rod 643 is hingedly arranged at one end of the swing rod 642 away from the fixed frame 1, and the other end is hingedly arranged on the movable rod 61. Thus, when the pull rod 641 moves along its axis, the position of the pressure jaw 62 can be indirectly adjusted.

[0046] Specifically, in this embodiment, when the on-site debugging tool is debugged, the inclination angle of the inclined plate 3 needs to be debugged. According to the present application, through the design of the swing rod 642 and the transmission rod 643, after the inclination angle of the inclined plate 3 changes during debugging, the position and angle of the pull rod 641 and the movable rod 61 do not need to be adjusted, and the pull rod 641 and the movable rod 61 can still be stably connected.

[0047] In some embodiments, the positioning disc 4 can adopt the structure as shown in Figure 4 . Referring to Figure 4 , the positioning disc 4 is detachably mounted on the inclined plate 3, and the positioning disc 4 comprises a mounting portion for mounting on the inclined plate 3 and a positioning portion for positioning the structural member.

Thus, the position of the mounting portion on the inclined plate 3 can be positioned, and the relative position of the mounting portion and the positioning portion can be adjusted according to the needs of different specifications of the structural member, so as to meet the processing of different structural members.

[0049] Specifically, in the embodiment, when replacing structural members of different specifications, only the positioning disc 4 and the inclination angle of the inclination plate 3 need to be disassembled and adjusted, then the corresponding positioning disc 4 is replaced and the position of the positioning pin 51 on the stop block 5 is readjusted, so that the tool is convenient for processing structural members of different specifications.
