A pressing block 222 with a V-shaped opening can be provided in the middle of the movable pressing plate 221, and the fixing of the pressing block 222 on the movable pressing plate 221 can be installed by screws or welding. The workpiece is pressed together by the V-shaped groove of the V-block and the V-shaped opening of the pressing block 222.

[0035] Specifically, the movable pressing plate 221 may be a bending arm and a vertical arm formed or welded in one piece, and the end of the bending arm is rotatably connected to a rotating block provided on the end of the V-shaped block 211, and the rotatable connection method may be a hinge or the like. The pressing block 222 is fixed to the vertical arm close to the bending arm, and the locking portion 23 is installed on the vertical arm away from the bending arm.

[0036] The locking part 23 in the above embodiment specifically includes a movable bolt 231 and a locking nut 232. One end of the movable bolt 231 fixes the mounting member 21. The pressure plate is provided with a groove. The outer circumferential surface of the movable bolt 231 is clamped in the groove. The other end of the movable bolt 231 extends out of the groove and screws on the locking nut 232.

[0037] Specifically, in this embodiment, the live bolt 231 is fixed to the end of the V-shaped block 211 disposed opposite to the bending arm, the outer circumferential surface of the screw rod of the live bolt 231 is clamped in the groove of the vertical arm in the movable pressing plate 221, and the locking nut 232 is screwed on the live bolt 231. After the workpiece is pressed together by the V-shaped groove of the V-block and the V-shaped opening of the pressing block 222, the live bolt 231 is rotated to insert the screw rod part into the groove of the movable pressing plate 221, and then the nut on the live bolt 231 is locked to fix the fixed part on the clamping part 2.

[0038] Optionally, the base 1 includes a bottom plate 12, a vertical plate 11 and an inclined plate 13, the bottom plate 12 is vertically arranged with the vertical plate 11, the inclined plate 13 connects the bottom plate 12 and the vertical plate 11, and the bottom of the V-shaped block 211 is vertically arranged on the bottom plate 12. The bottom plate 12 is provided with a through hole 111, and the clamping member 2 is placed around the center of the through hole 111.

[0039] In this embodiment, the bottom plate 12 in the base 1 is set on the workbench of the machining center, wherein the clamping piece 2 is vertically fixed on the vertical plate 11, and the bottom of the V-shaped block 211 can be connected to the vertical plate 11 by screws or welding. The inclined plate 13 is inclined against the interval between the vertical plates 11 where the bottom plate 12 is set, which is used to further improve the stability of the base 1.

Before clamping the workpiece, when the workpiece is placed in the groove of the V-shaped block 211, the end face of the workpiece that does not need to be processed is first abutted against the limit block 24, and then the workpiece is pressed by the V-shaped groove of the V-block and the V-shaped opening of the pressing block 222, and then the movable bolt 231 is rotated to insert the screw rod part into the groove of the movable pressure plate 221, and then the nut on the movable bolt 231 is tightened to fix the fixing member on the clamping member 2.

[0041] As an alternative implementation, see Figure 1After the workpiece is clamped, before the workpiece is processed, the tool in the machining center needs to be aligned. In this embodiment, two tool alignment methods can be adopted. The above-mentioned machining fixture can be used for clamping to realize that multiple workpieces can be processed in one clamping. The workpiece in this embodiment is a pipe joint 100. The first method can use the outer circumference of the pipe joint 100 to face the tool, and convert to determine the height of the machine tool spindle (the center height of the curved surface); use the end face of the pipe joint 100 to face the tool, and convert to determine the distance between the machine tool spindle and the end face of the pipe joint 100 (the radius R and L of the curved surface). Compared with the first tool alignment method, there will be a problem that the shape of the pipe joint 100 is used for tool alignment, which causes the curved surface to be easily skewed relative to the circular tube, resulting in poor quality. In this embodiment, the second tool alignment method can be adopted, that is, the through hole 111 opened on the bottom plate 12 is used for tool alignment, and the position of the workbench is adjusted so that the through hole 111 in the fixture position is concentric with the machine tool spindle.

[0042] Specifically, the process of using the above-mentioned clamp is as follows: (1) Preliminary work, place the clamp on the working table of the boring machine, use the machine tool's own pressure plate to fix the clamp, use the through hole 111 on the base 1 to align the tool, and adjust the position of the workbench so that the through hole 111 is concentric with the machine tool spindle. (2) During use, place the pipe joint 100 to be processed on the V-block 211, and the end of the pipe joint 100 is close to the limit block 24; turn over the movable pressure plate 221, so that the V-shaped opening of the pressing block 222 is close to the outer circumference of the pipe joint 100; turn the movable bolt 231, so that its screw rod part is inserted into the groove of the movable pressure plate 221, and then tighten the locking nut 232 on the movable bolt 231; after boring the curved surface, loosen the locking nut 232, so that the movable bolt 231 is rotated out of the groove of the movable pressure plate 221, open the movable pressure plate 221, and take out the processed pipe joint 100.

[0043] See also Figure 3 and Figure 4 , Figure 3 A schematic diagram of the structure of a pipe joint before processing in a cooling water pipe joint processing fixture provided by an embodiment of the utility model; Figure 4 A schematic diagram of the structure of a pipe joint after processing in a cooling water pipe joint processing fixture provided by an embodiment of the utility model; the specific processing method of the workpiece includes the following:

[0044] Step 1: Select a suitable boring tool according to the processing requirements, usually a metal tool;

[0045] Step 2: Install the workpiece to be processed on the fixture 2, and the fixture 2 is installed on the working table of the boring machine;

[0046] Step 3: The tool setting operation can be completed according to the above-mentioned tool setting method.

[0047] Step 4: Feed the boring cutter in the axial direction through the feeding system of the boring machine. The feeding can be manual or automatic.

[0048] Step 5: While feeding, the boring cutter rotates and contacts the workpiece, and the metal material of the workpiece is removed by tools such as arc cutters, gradually forming a water pipe joint 100 of a desired shape and size.

[0049] Step 6: During the cutting process, cooling lubrication system is used to spray cooling lubricant into the cutting area to reduce cutting temperature, reduce cutting resistance and extend tool life.

[0050] Step 7: As needed, the workpiece can be inspected and measured during the processing to ensure the accuracy and quality of the processing.

[0051] Step 8: When the workpiece reaches the required size and shape, stop feeding and cutting to complete the entire boring machine processing process.
