DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] like Figure 1 to Figure 2 As shown, a turning inner support fixture in one embodiment of the utility model includes a mounting tube 2, an elastic collet 1, a pull rod 3 and a second mounting plate 6. It is fixed on a machine tool and the thin-walled pipe to be processed is fixed, which is convenient for later processing.

[0023] One end surface of the mounting tube 2 is fixedly connected to the first mounting plate 5 , so that the mounting tube 2 is fixed to the one end surface of the first mounting plate 5 .

[0024] Furthermore, a third thread is provided on the end surface of the mounting tube 2 that contacts the first mounting plate 5 , and the mounting tube 2 is threadedly connected to the first mounting plate 5 via the third thread, so that the mounting tube 2 is fixed on the first mounting plate 5 .

[0025] The elastic collet 1 is sleeved on the outer end face of the mounting tube 2. A mounting tube rear end conical surface 201 is provided on one end face of the mounting tube 2. The elastic collet 1 is sleeved on the mounting tube 2 and on one end face of the mounting tube rear end conical surface 201.

[0026] Furthermore, the projection of the tapered surface 201 at the rear end of the mounting tube on the horizontal plane is larger than the projection of the elastic collet 1 on the horizontal plane, so as to facilitate the limitation of the current position of the elastic collet 1.

[0027] The mounting tube 2 is a hollow end surface, and the tie rod 3 passes through the middle end surface of the mounting tube 2, that is, the tie rod 3 passes through the first mounting plate 5 and the second mounting plate 6, and one end surface of the tie rod 3 protrudes from one end surface of the second mounting plate 6. The second mounting plate 6 is fixedly connected to one end surface of the first mounting plate 5.

[0028] The elastic collet 1, the mounting tube 2 and the pull rod 3 are all fixedly connected, so as to control the elastic collet 1 to be expanded, and then support the thin-walled part sleeved on the elastic collet 1 to be fixed.

[0029] Furthermore, the mounting tube 2 is provided with a mounting tube U-shaped hole 202, the elastic collet 1 is provided with a collet circular hole 101 matching the mounting tube U-shaped hole 202, the pull rod 3 is provided with a pull rod circular hole 301 matching the collet circular hole 101, and the collet circular hole 101, the pull rod circular hole 301 and the mounting tube U-shaped hole 202 are all connected with an elastic pin 4. The three parts are connected together by using the elastic pin 4.

[0030] Specifically, under the fixing action of the elastic pin 4, the elastic collet 1 can move on the U-shaped hole 202 of the mounting tube 2. There is a rear end conical surface 201 of the mounting tube at the rear end of the mounting tube 2. When the pull rod 3 is pulled backward, the elastic collet 1 expands under the limiting action of the rear end conical surface 201 of the mounting tube. When the pull rod 3 is pushed forward, the elastic collet 1 returns to its original position.

[0031] It should be noted that the principle of the elastic pin 4 is that the main body diameter is larger than the hole diameter, and one or both ends are chamfered to facilitate the insertion of the pin into the hole. The fixing and installation methods of the elastic pin 4 are common knowledge in the art and will not be repeated here.

[0032] The second mounting plate 6 is provided with a plurality of first threaded holes 601 , the first mounting plate 5 is provided with a fourth threaded hole matching the plurality of first threaded holes 601 , and the fourth threaded hole and the first threaded hole 601 are both threadedly connected with a first fixing bolt 7 , so as to fix the first mounting plate 5 on the second mounting plate 6 .

[0033] The second mounting plate 6 is provided with a plurality of second threaded holes 602, the inner threads of the plurality of second threaded holes 602 are connected with second fixing bolts 8, and the second fixing bolts 8 are threadedly connected to the third threaded holes on the processing machine tool, so that the turning inner support fixture can be fixed on the machine tool for processing by the second fixing bolts 8.

[0034] The machine tool includes a third threaded hole, a push-pull rod and a processing table, and the push-pull rod is provided with a second thread. This is common knowledge in the art and will not be described in detail here.

[0035] A first thread matching the second thread is provided on one end face of the pull rod 3. The pull rod 3 is threadably connected and fixed to the second thread on the push-pull rod of the machine tool through the first thread, thereby fixing the pull rod 3 on the push-pull rod, making it convenient to control the movement of the pull rod 3 through the push-pull rod later.

[0036] When using, Figure 1 As shown, when the pull rod 3 is at the front end, the thin-walled part is put on the elastic collet 1, and the elastic pin 4 is used to connect the elastic collet 1, the mounting tube 2 and the pull rod 3, and then the machine tool is controlled to move the pull rod backward, the elastic collet 1 expands, clamps the thin-walled part, and then the machining is performed. It is easy to fix the thin-walled parts, and it is not easy to fail in machining due to the inability to clamp the thin-walled pipe fittings, and the work efficiency is high.
