DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 is a schematic structural diagram of a preferred embodiment of the positioning device for flange lathe machining provided by the present utility model; Figure 2 is Figure 1 the left view schematic diagram shown in Figure 3 is Figure 1 the top view schematic diagram shown in Figure 4 is Figure 1 the internal structure schematic diagram shown in Figure 5 is Figure 1 the sectional view schematic diagram shown in

[0022] When the operator manually rotates the rotating rod 5, the bottom circular block 4 installed at one end of the rotating rod 5 rotates. A top groove 6 is opened at the top of the bottom circular block 4, and an insertion block 7 is inserted into the top groove 6. By adopting the insertion method, rapid operation can be carried out during maintenance. A rotating block 8 is installed at the top of the insertion block 7 to drive the rotating block 8 to rotate. A convex block 9 is installed outside the rotating block 8. A support frame 12 is installed outside the circular cover 11, and a rotating shaft 13 is installed inside the support frame 12. A buckle rod 14 is movably connected to the outside of the rotating shaft 13. When the convex block 9 rotates together with the rotating block 8, the extension rod 15 can be pushed outwards.

[0023] A side locking block 17 is fixedly connected to the top of the base 1. A straight groove opening 18 is opened outside the side locking block 17, and the rotating rod 5 is movably connected to the inside of the straight groove opening 18. A compression spring 19 is arranged outside the rotating rod 5. An arc-shaped block 20 is movably connected to the outside of the rotating rod 5. The other end of the rotating rod 5 is fixedly connected to a limiting block 21.

[0024] When the arc-shaped block 20 is moved to one side by a person, the compression spring 19 is compressed. The person then pushes the rotating rod 5. When the position is determined and the arc-shaped block 20 is released, the compression spring 19 tightly fits the moving arc-shaped block 20 and the side locking block 17 to prevent the bottom circular block 4 from loosening.

[0025] A mounting plate 22 is fixedly connected to the top of the base 1, and a mounting bolt 23 is threadedly connected to the top of the mounting plate 22.

[0026] Since the mounting bolt 23 is threadedly connected to the top of the mounting plate 22, it is convenient to install at different positions according to the needs of the flange lathe. At the same time, the large external area of the mounting plate 22 can better fix it to the flange lathe.

[0027] A rubber skin 24 is fixedly connected to one side of the semi-circular block 16.

[0028] The rubber skin 24 can increase the friction when the buckling rod 14 fixes the flange, preventing it from loosening.

[0029] A frosted block 25 is fixedly connected to the outside of the side locking block 17, and a grinding block 26 is fixedly connected to the outside of the arc-shaped block 20.

[0030] The frosted block 25 on the outside of the locking block increases the friction when the arc-shaped block 20 is tightly fitted. At the same time, the grinding block 26 and the frosted block 25 can be better stabilized.

[0031] A fixing bolt 27 is threadedly connected to the outside of the fixing block 10.

[0032] With the fixing bolt 27, the circular cover 11 can be quickly replaced and repaired, avoiding welding between the base 1 and the fixing block 10.

[0033] The working principle of the positioning device for flange lathe processing provided by the present utility model is as follows: When a person manually rotates the rotating rod 5, the bottom circular block 4 installed at one end of the rotating rod 5 rotates. A top groove 6 is provided at the top of the bottom circular block 4, and a plug block 7 is inserted into the top groove 6. By using the insertion method, rapid operation can be achieved during maintenance. A rotating block 8 is installed on the top of the plug block 7 to drive the rotating block 8 to rotate. A convex block 9 is installed outside the rotating block 8. A support frame 12 is installed outside the circular cover 11, and a rotating shaft 13 is installed inside the support frame 12. A buckling rod 14 is movably connected to the outside of the rotating shaft 13. When the convex block 9 rotates with the rotating block 8, the extension rod 15 can be pushed outwards. The extension rod 15 is installed with the buckling rod 14, so that when the buckling rod 14 closes towards the inside of the circular cover 11, the flange is fixed.

[0034] Compared with the related technology, the positioning device for flange lathe processing provided by the present utility model has the following beneficial effects:

[0035] The utility model provides a positioning device for lathe processing of flange plates. By adding a rotating mechanism to the top of the device, under the mutual cooperation of the short column 2, the bottom round block 4, the top groove 6, the insertion block 7, and the rotating block 8, rotating the bottom round block 4 can drive the insertion block 7 inside the top groove 6 to rotate. At the same time, in the way that the insertion block 7 and the rotating block 8 are fixedly connected, the edge round block outside the rotating block 8 rotates. Through the rotation, the telescopic rod 15 is telescoped, and the shape of the buckle rod 14 is changed through the telescopic action. By changing the shape, the flange plate can be quickly taken, avoiding the cumbersome operation to take out the flange plate.

[0036] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
