[0036] The sliding clamping seats 130 include two, each of which includes a slider 131 and a mounting block 132 fixed on the slider 131, and the two sliding clamping seats 130 are slidably connected to the track 160 through their respective sliders 131;

[0037] One side of the bidirectional lead screw 120 is rotatably connected to the stand 111 through a bearing, and the other side passes through the sliders 131 on the two sliding clamping seats 130 in sequence, and the two sliders 131 are respectively located on the two reverse threads of the bidirectional lead screw 120; by rotating the bidirectional lead screw 120, the two sliding clamping seats 130 can move towards or in the opposite direction;

[0038] The clamping arms 150 include two, each of which includes a connecting plate 151 and a clamping plate 153 fixedly connected to the connecting plate 151; the connecting plate 151 is provided with a first mounting hole 152; the clamping plate 153 is provided with a V-shaped groove, and a plurality of sawtooth blocks 153a are provided on the groove wall of the V-shaped groove; the V-shaped groove is used to clamp the pipe fitting, and the provision of the sawtooth blocks 153a can improve the clamping force;

[0039] The mounting block 132 is provided with a mounting groove 132a, and the mounting block 132 is provided with a second mounting hole 131a penetrating two opposite groove walls of the mounting groove 132a, the bolt 140 penetrates and is connected to the second mounting hole 131a on the mounting block 132, and a nut is connected to the tail of the bolt 140 to lock the bolt 140 on the mounting block 132;

[0040] The connecting plate 151 of the clamping arm 150 is located in the mounting groove 132 a , and the first mounting hole 152 on the connecting plate 151 is hinged on the bolt 140 .

[0041] In this embodiment, the thickness of the clamping plate 153 is greater than the thickness of the connecting plate 151; the purpose of this structural setting is to increase the thickness of the clamping plate 153, increase the clamping area of ​​the clamping plate 153 in contact with the pipe fitting, and improve the clamping stability.

[0042] In this embodiment, the position where the bolt 140 and the first mounting hole 152 are hinged is a bare rod; the setting of the bare rod facilitates the hinge connection between the bolt 140 and the first mounting hole 152 on the connecting plate 151; at the same time, the connecting plate 151 is not freely rotatable relative to the bolt 140, and the first mounting hole 152 on the connecting plate 151 and the connection position of the bolt 140 have a certain pre-tightening force, and the connecting plate 151 can only rotate relative to the bolt 140 under the action of external force.

[0043] In this embodiment, a rotating handle 121 is fixed to one end of the bidirectional lead screw 120 close to the stand 111 ; the rotating handle 121 is provided to facilitate the operation of the bidirectional lead screw 120 .

[0046] The operating method of a cast steel pipe bench vise provided by the embodiment of the utility model is as follows:

[0047] 1. When performing the pipe clamping operation, the worker places the pipe on the V-shaped grooves of the two clamping arms 150, and rotates the bidirectional lead screw 120 to move the two clamping arms 150 toward each other to clamp the pipe;

[0048] 2. At the same time, because the clamping arms 150 are hinged on the sliding clamping seat 130, if the pipe fitting is not accurately placed at the center position of the two V-shaped grooves, the two clamping arms 150 will automatically adjust their positions when moving toward each other for clamping operation to adapt to the offset of the pipe fitting, so that the pipe fitting is in the center position when being clamped.

[0049] The utility model provides a cast steel pipe bench vise, which has the following beneficial effects: the utility model designs a cast steel pipe bench vise, which is easy to operate, can facilitate pipe clamping operations, and improves operating efficiency.
