DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1-Figure 5 As shown, in the embodiment of the utility model, a pipe wire cutting fixture is proposed, which is mainly used in the wire cutting equipment, and the position and angle of the pipe are adjusted according to the wire running direction to meet the arc structure cutting, such as Figure 1 As shown in the figure, the outer arc structure is processed on the pipe, or as shown in the figure, the outer arc structure is processed on the pipe. Figure 2 As shown, an inner arc structure is processed on a pipe. Specifically, during online cutting, due to the different sizes of pipes and arc structures, a clamp is used to clamp and fix them, and the online cutting equipment is installed on a machine base that can be moved in the X and Y directions, so that the moving track of the pipe cutting position meets the needs of arc structure cutting. The specific principle of arc structure cutting is the existing principle. The utility model is to clamp and fix the pipe according to the predetermined position and angle before moving.

[0028] Specifically, the clamp includes a base 1 and a sliding rod 2 vertically fixed on the base 1, a slider 3 is slidably installed on the sliding rod 2, and the slider 3 is provided with a locking member 4 for locking its sliding relative to the sliding rod 2; a clamping tool 5 is rotatably installed on the slider 3, and the clamping tool 5 is provided with a clamping cavity 6 with an adjustable inner diameter for clamping pipe fittings, and a locking mechanism 7 is installed on the slider 3 for locking the rotation adjustment angle of the axis of the clamping cavity 6 relative to the axis of the sliding rod 2.

[0029] The entire clamp is fixed on the mobile platform of the wire cutting equipment through the base 1, and the pipe is placed in the clamping cavity 6 and fixed through the clamping tool 5. The position of the slider 3 relative to the slide rod 2 is adjusted by sliding according to the arc structure size to be cut, and then locked by the locking member 4. After the angle of the entire clamping tool 5 is rotated and adjusted relative to the slider 3, the adjusted angle is locked by the locking mechanism 7, thereby achieving the clamping and fixing of the pipe in the adjusted state, and realizing processing in cooperation with the cutting work of the wire cutting equipment.

[0030] Specifically, the slider 3 includes a sliding sleeve 31 slidably installed on the sliding rod 2 and a fixed block 32 fixed on the sliding sleeve 31. The clamping tool 5 is installed on the fixed block 32 through the locking mechanism 7. The sliding sleeve 31 is used to achieve sliding adjustment relative to the sliding rod 2, and the fixed block 32 supports and installs the clamping tool 5. Specifically, the fixed block 32 and the sliding sleeve 31 can be welded to facilitate processing, or they can be processed by an integrated molding method.

[0031] After the sliding sleeve 31 slides relative to the slide bar 2, it is locked by the locking member 4, and the locking member 4 includes a first locking bolt threadedly connected to the sliding sleeve 31, and the slider 3 is fastened to the slide bar 2 by tightening the first locking bolt. In addition, the locking member 4 can also use a fastening screw or a fastening pin to lock the relative position of the sliding sleeve 31 relative to the slide bar 2 after sliding. Of course, other locking members 4 that can achieve relative position locking can also be used.

[0032] The clamping tool 5 clamps and fixes the pipe fitting, and can clamp and fix the pipe fitting according to the change of the size of the pipe fitting. Specifically, the clamping tool 5 includes a first clamping block 51 and a second clamping block 52. The first clamping block 51 is installed on the fixing block 32 through a locking mechanism 7. Two screws are installed on the first clamping block 51 at intervals. The second clamping block 52 is sleeved on the two screws. The position where the screw passes through the second clamping block 52 is provided with a first locking nut. At the same time, a first positioning groove 55 is provided on the first clamping block 51, and a second positioning groove 56 is provided on the second clamping block 52. The first positioning groove 55 and the second positioning groove 56 enclose a clamping cavity 6. The interval between the second clamping block 52 and the first clamping block 51 is adjusted by the cooperation of the first locking nut and the screw, thereby realizing the adjustment of the size of the clamping cavity 6 formed by the first positioning groove 55 and the second positioning groove 56 until the pipe fitting is tightened, ensuring that the pipe fitting will not slide relative to the clamping tool 5.

[0033] The second embodiment can also be used for the relative position tightening between the first clamp block 51 and the second clamp block 52. Specifically, two threaded holes 54 are opened on the first clamp block 51 and spaced apart. The third locking bolt 53 passes through the second clamp block 52. The third locking bolt 53 is fastened to the threaded hole 54. The second clamp block 52 is locked relative to the first clamp block 51 by the cooperation between the third locking bolt 53 and the threaded hole 54.

[0034] Specifically, in order to allow the clamping cavity 6 to adapt to the clamping of the pipe, the cross-sections of the first positioning groove 55 and the second positioning groove 56 can be V-shaped, arc-shaped or semicircular, which can achieve clamping and limiting of the circumferential wall of the pipe.

[0035] After the locking mechanism 7 is installed on the clamping tool 5, it cannot affect the clamping of the clamping cavity 6 on the pipe fitting. Therefore, the locking mechanism 7 includes a step hole 71 arranged on the first clamping block 51, and a mounting hole 72 corresponding to the step hole 71 is opened on the fixing block 32. A second locking bolt 73 passing through the step hole 71 and the mounting hole 72 is provided in the step hole 71, and a second locking nut 74 is provided at the position where the second locking bolt 73 passes through the mounting hole 72; the head of the second locking bolt 73 is hidden and stopped from rotating through the step hole 71, and the tightness can be adjusted through the second locking nut 74 when adjusting the rotation, so as to quickly realize the locking after the angle adjustment of the entire clamping tool 5.

[0036] Specifically, in this embodiment, the adjustment range of the inner diameter of the clamping cavity 6 is 10 mm to 50 mm, and the pipe fittings within this size range are adapted and clamped.
