It includes a base, a first mounting column, a second mounting column, a first connecting column, a first support plate, a transmission bar, a second connecting column, a second support plate, a first clamping plate, a first guide bar, a driving plate and a second guide bar. The middle part of the second guide bar is hinged on the second mounting column and can rotate around the central axis of the second mounting column. The end of the bottom of the second guide bar away from the transmission bar is fixedly connected with a second clamping plate, and the bottom ends of the first clamping plate and the second clamping plate are flush. In the utility model, when the first guide bar rotates around the central axis of the first mounting column, the first clamping plate and the second clamping plate are simultaneously driven to move toward the steel, which is conducive to clamping and fixing the steel, and the clamping effect is good.

[0004] The device automatically controls the rotation of the first mounting column through a motor to clamp and fix the steel. However, this clamping method can easily cause the position of the steel to change during clamping, causing the midpoint of the steel to be misaligned with the processing equipment, thereby affecting the processing effect of the steel.

[0010] Preferably, a guide rod is fixedly mounted on the inner side of the support plate, and a guide block is nested on the outer side of the guide rod; this structure can limit the angle of the threaded connector by sliding the guide block on the outer side of the guide rod.

[0011] Preferably, an anti-skid pad is fixedly installed on the inner side of the clamping plate; this structure can prevent the two ends of the steel from slipping when the steel is clamped by the provision of the anti-skid pad.

[0012] Preferably, a fixing plate is fixedly installed on the upper end of the base, and a coaxial shaft is rotatably connected to the inner side of the fixing plate, a rotating disk is fixedly installed on the outer side of the concentric shaft, and limiting holes are provided at equal angles on the inner side of the rotating disk; this structure can control the state of the rotating disk by engaging the limiting rod with the limiting hole on the inner side of the rotating disk.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the steel material clamping structure with center positioning function is provided with:

[0015] 1. Center positioning structure. This structure installs clamping plates symmetrically on the left and right sides of the storage plate. When the steel needs to be clamped and fixed, the servo motor is operated. The output end of the servo motor drives the counter-rotating threaded rod to rotate. The rotation of the counter-rotating threaded rod drives the threaded connectors at both ends to move toward each other.

[0016] Furthermore, the clamping plates at both ends are installed symmetrically, and when they move toward each other, the lengths of the two sides of the steel material are always kept consistent, so that the midpoint of the steel material is always consistent with the midpoint of the storage plate, thereby achieving the effect of center positioning;

[0017] 2. Angle adjustment structure. When the clamping angle of the steel needs to be adjusted, the limit rod is first pulled to separate the tail end of the limit rod from the limit hole on the inner side of the rotating disk. After separation, the rotating disk is in an active state. The rotating disk is manually rotated to drive the concentric shaft to rotate. The rotation of the concentric shaft will drive the first bevel gear at the tail end to rotate. The rotation of the first bevel gear will drive the second bevel gear on the outside to rotate. The rotation of the second bevel gear will drive the rotating pillar at the upper end of the base to rotate together.
