Background Art

[0002] In mechanical processing, the processing of waist-shaped holes is a common task, but waist-shaped holes are usually processed using milling machines. However, in some processing environments, only lathes are available. The existing technology cannot directly use lathes to process the waist-shaped holes of bent workpieces; and in traditional milling machine processing, if the workpiece bent 90° is fixed on the milling machine, it is often necessary to adjust the workpiece position and fixture multiple times, which is not only time-consuming and labor-intensive, but also easily leads to a decrease in processing accuracy.

[0004] However, the above patented technology cannot process waist-shaped holes on bent workpieces, nor can it solve the technical problems existing in the existing technology. Therefore, it is particularly important to develop a special tooling that can efficiently and accurately complete waist-shaped hole processing. Utility Model Content

[0038] The special tooling for horizontal milling of waist-shaped holes for a lathe comprises a base 100 , a first positioning plate 200 , a second positioning plate 300 , a third positioning plate 400 , a first clamping assembly and a second clamping assembly.

[0039] The first positioning plate 200 and the second positioning plate 300 are respectively welded and fixed to the upper end surface of the base 100. A clamping area for placing the workpiece 700 to be processed is reserved between the first positioning plate 200 and the second positioning plate 300. A first threaded hole communicating with the clamping area is opened on the side wall of the second positioning plate 300. The third positioning plate 400 is also welded and fixed to the upper side of the base 100. The third positioning plate 400 is located next to the clamping area, and the third positioning plate 400 is opened with a second threaded hole.

[0040] The first clamping assembly includes a clamping plate 510, a first rotating handle 530 and a first screw 520. The clamping plate 510 is in the clamping area. The first screw 520 cooperates with the first threaded hole of the second positioning plate 300 and the end of the first screw 520 is welded and fixed to the clamping plate 510. The first rotating handle 530 is welded and fixed to the starting end of the first screw 520.

[0041] The second clamping assembly includes a baffle 610, a second screw 620, a rotating ring 640, a second rotating handle 630 and a positioning cover 650. The baffle 610 is also in the clamping area. The second screw 620 cooperates with the second threaded hole of the third positioning plate 400 and the end of the second screw 620 is connected to the baffle 610.

[0042] The positioning cover 650 is fixedly connected to the third positioning plate 400, and a rotating chamber is formed between the positioning cover 650 and the side wall of the third positioning plate 400. The rotating chamber is communicated with the second threaded hole. The rotating ring 640 is in the rotating chamber. The end of the second screw 620 is welded and fixed to the rotating ring 640. The rotating ring 640 can rotate freely in the rotating chamber. The second rotating handle 630 is fixedly connected to the starting end of the second screw 620.

[0043] The baffle 610 can reciprocate along the clamping area, and the baffle 610 is respectively matched with the first positioning plate 200 and the second positioning plate 300 through rails.

[0044] Before use, ensure that the lathe is in a safe and stable working condition and check whether all parts of the lathe are intact. At the same time, prepare the special tooling for horizontal milling waist holes on the lathe.

[0045] Place the base 100 of the horizontal milling waist hole special tooling for the lathe under the lathe tool post, and fix the base 100 to the lathe tool post with bolts for detachable connection. Ensure that the base 100 is firmly installed without shaking.

[0046] Install the first clamping assembly (including the clamping plate 510, the first screw 520, and the first rotating handle 530) onto the second positioning plate 300 and check whether it works smoothly. At the same time, install the second clamping assembly (including the baffle 610, the second screw 620, the rotating ring 640, the positioning cover 650, and the second rotating handle 630).

[0047] The workpiece 700 is positioned and clamped, and the 90° bent workpiece 700 to be processed is gently placed in the clamping area between the first positioning plate 200 and the second positioning plate 300 to ensure that the workpiece 700 is tightly fitted to the first positioning plate 200.

[0048] The first clamping assembly is used to initially clamp the workpiece 700. By rotating the first rotating handle 530, the first screw 520 is driven to move along the first threaded hole on the second positioning plate 300, thereby driving the clamping plate 510 toward the workpiece 700 until the clamping plate 510 is in close contact with the surface of the workpiece 700, thereby achieving initial positioning and clamping of the workpiece 700.

[0049] The second clamping assembly is used to clamp the side of the workpiece 700. Rotating the second rotating handle 630 drives the second screw 620 to rotate, which in turn drives the rotating ring 640 to rotate within the rotating chamber of the positioning cover 650. Because the rotating ring 640 is fixedly connected to the baffle 610, as the second screw 620 rotates, the baffle 610 moves closer to the workpiece 700 until it comes into close contact with the side of the workpiece 700, thereby clamping the side of the workpiece 700.

[0050] Install the drill bit for horizontally milling the waist-shaped hole onto the lathe's spindle, ensuring that the drill bit is aligned with the area to be machined on the workpiece 700. Start the lathe and allow the drill bit to follow the pre-set path. During machining, carefully observe the progress of the workpiece 700. If any abnormality is detected, stop the lathe and inspect it immediately. Once the waist-shaped hole is complete, stop the lathe and turn off the power. Then, loosen the clamping assembly and remove the workpiece 700 from the dedicated tooling for horizontally milling waist-shaped holes on this lathe.

[0051] The above is only one embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the principles of the present invention, and these should also be regarded as falling within the scope of protection of the present invention.
