[0023] Among them, the processing is completed by changing the clamping position. The workpiece body 2 is vertically fixed on the boring machine working platform 3 by the clamping tool 1. The original fixing method requires the workpiece body 2 to be turned over and clamped four times during the processing. The workpiece body 2 has a large dead weight and is difficult to lift and transport. When the original clamping method is used to clamp the workpiece body 2, the clamping operation of the workpiece body 2 is inconvenient and there is a great safety hazard. When clamping the workpiece body 2, it is time-consuming and labor-intensive, thereby reducing the processing efficiency of the workpiece body 2.

[0024] Among them, the large end of the workpiece body 2 is vertically fixed on the boring machine working platform 3 by the clamping fixture 1. The clamping fixture 1 is a one-time clamping, and the processing is completed by rotating the boring machine working platform 3. There is no need to turn over and clamp the workpiece body 2 multiple times, which greatly reduces the time required for positioning clamping and reference adjustment. The processing can be completed after one clamping. In particular, the workpiece body 2 can be easily disassembled, which makes it convenient to install and disassemble the workpiece body 2, and to position and clamp it, thereby improving production efficiency.

[0027] In some examples, the second mounting hole 19 and the third mounting hole 110 are both configured as screw hole structures, which are adapted to the second fixing bolt 6, and the second fixing bolt 6 can be screwed in and out normally, the first frame plate 12 and the second frame plate 13 are arranged parallel to each other, the third frame plate 14 and the fourth frame plate 15 are arranged parallel to each other, and the third frame plate 14 and the fourth frame plate 15 are arranged perpendicular to the first frame plate 12 and the second frame plate 13, the third frame plate 14 is located on one side between the first frame plate 12 and the second frame plate 13, and the fourth frame plate 15 is located on the other side between the first frame plate 12 and the second frame plate 13.

[0028] Among them, the first frame plate 12, the second frame plate 13, the third frame plate 14 and the fourth frame plate 15 together constitute a frame structure, through which the workpiece body 2 is clamped, and the large end of the workpiece body 2 is placed in the frame structure of the clamping fixture 1, and the workpiece body 2 is vertically fixed on the boring machine working platform 3 through the clamping fixture 1 for processing.

[0029] In some examples, a plurality of groups of grooves 31 are provided on the boring machine working platform 3.

The boring machine working platform 3 can make a rotational motion. When the boring machine working platform 3 moves, it drives the clamping fixture 1 fixed on the upper part thereof to move synchronously. When the workpiece body 2 is fixed on the clamping fixture 1, the workpiece body 2 moves synchronously with the clamping fixture 1 and makes a rotational motion synchronously under the drive of the boring machine working platform 3. The base plate 11 of the clamping fixture 1 is fixedly connected to the boring machine working platform 3 by a locking member 4 and a first fixing bolt 5. The first fixing bolt 5 passes through the first mounting hole 18 on the base plate 11.

[0030] Among them, when fixing the boring machine working platform 3 and the clamping fixture 1, the base plate 11 of the clamping fixture 1 is placed on the plane of the boring machine working platform 3, and the base plate 11 of the clamping fixture 1 is locked and fixed on the boring machine working platform 3 through the matching locking piece 4 and the first fixing bolt 5, completing the installation and fixation of the clamping fixture 1.

The workpiece body 2 and the clamping fixture 1 are detachably connected.

[0032] In some examples, the second fixing bolt 6 is threadedly connected to the second mounting hole 19 , and the second fixing bolt 6 is threadedly connected to the third mounting hole 110 .

By rotating the multiple groups of second fixing bolts 6, one end of the second fixing bolts 6 is driven to be tightly attached to the surface of the workpiece body 2, so as to achieve clamping and fixing of the workpiece body 2. When disassembling, it is only necessary to use tools to loosen the multiple groups of second fixing bolts 6 to release the locking fixation of the workpiece body 2.

[0034] In some examples, the bottom plate 11 is welded and fixedly connected to the first frame plate 12 and the second frame plate 13, two ends of the third frame plate 14 are respectively welded and fixedly connected to the first frame plate 12 and the second frame plate 13, two ends of the fourth frame plate 15 are respectively welded and fixedly connected to the first frame plate 12 and the second frame plate 13, the reinforcing plate 17 is set as a triangular plate structure, and one side of the reinforcing plate 17 is welded and fixedly connected to the bottom plate 11, and the other side of the reinforcing plate 17 is welded and fixedly connected to the first frame plate 12 and the second frame plate 13, the pad 16 is welded and fixedly connected to the bottom plate 11, and the clamping tool 1 is welded and fixed, and the bottom plate 11, the first frame plate 12, the second frame plate 13, the third frame plate 14, the fourth frame plate 15, the pad 16 and the reinforcing plate 17 are fixed together to form a whole by welding, with low production cost, high structural strength and good sealing of the welding connection method, simple production process and low production cost.

[0035] By adopting the above technical solution: The workpiece body 2 is vertically fixed on the boring machine working platform 3 by the clamping fixture 1, and the processing is completed by changing the clamping position. The clamping fixture 1 is a one-time clamping, and the processing is completed by rotating the boring machine working platform 3. There is no need to turn over and clamp the workpiece body 2 multiple times, which greatly reduces the time required for positioning clamping and reference adjustment. The processing can be completed after one clamping. In particular, the workpiece body 2 can be easily disassembled, and the workpiece body 2 is convenient to install and disassemble, and convenient to position and clamp, thereby improving production efficiency.

[0036] Embodiment 2: Based on Example 1, this example introduces a specific structure of a workpiece body 2 in a support box flip block boring tooling. The lifting ear 21 is welded and fixedly connected to the workpiece body 2. The original workpiece body 2 is not provided with the lifting ear 21 structure, which makes it inconvenient to lift the original workpiece.

[0037] In some examples, a lifting hole 22 is formed on the lifting ear 21 .

[0038] Among them, a lifting ear 21 structure is added at the top of the workpiece body 2, and the clamping and fixing method of the workpiece body 2 is shown in Figure 1. The workpiece body 2 is vertically fixed on the boring machine working platform 3, and the lifting ear 21 structure of the workpiece body 2 is set upward and located at the top. When installing, positioning and disassembling the workpiece body 2, since the workpiece body 2 has a large dead weight, it is necessary to use a lifting device to lift the workpiece body 2, and lift the workpiece body 2 to a designated position to realize loading and unloading. During the lifting process, the lifting ear 21 structure is used as a connection point, and the lifting device is connected to the lifting ear 21 structure. The lifting of the workpiece body 2 is realized through the lifting device, and the lifting and clamping are safe, and the lifting and disassembly are safe, which saves time and improves the production efficiency of the workpiece body 2.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
