The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

The embodiment of the utility model provides a: an adjustable opposite-core electroslag pressure welding fixture is shown in figures 1-5 and comprises a lower clamp holder 7, an upper clamp 3 and a gear box 1 which are sequentially arranged from bottom to top, a handle 2 is arranged on the gear box 1, double guide pillars 5 are vertically arranged on the lower clamp holder 7, the tops of the double guide pillars 5 are fixedly connected with the gear box 1 after the double guide pillars 5 slide through the upper clamp 3, the upper clamp 3 is further connected with the gear box 1 through a vertically arranged lifting screw 8, an upper clamping screw 4 and a lower clamping screw 6 horizontally penetrate through the upper clamp 3 and the lower clamp holder 7 are arranged on the upper clamp 3 and the lower clamp holder 7 respectively, the head end of the upper clamping screw 4 is a clamp connected with the upper clamp 3, the head end of the lower clamping screw 6 is provided with a lower clamp 10, the lower clamp 10 is movably connected with the lower clamp holder 7 to form a lower clamp, openings of the upper clamp 3 and the lower clamp 10 are of a symmetrical splayed structure, the upper clamp 4 and the lower clamping screw 6 are aligned with the middle positions of the clamp 3 and the splayed structure of the lower clamp 10, the upper clamp 3 and the lower clamp 10, the upper clamp and the lower clamp 10 are of the same structure, and the same upper cross section of the same structure is positioned at the same vertical opening end.

The openings of the chuck of the upper clamp 3 and the lower chuck 10 are arranged to be symmetrical splayed structures, the upper clamping screw 4 and the lower clamping screw 6 are aligned to the middle positions of the chuck of the upper clamp 3 and the splayed structure of the lower chuck 10, and the fixed position is only after the reinforcing steel bar is placed into the chuck and is tightly abutted by the clamping screws, so that the upper reinforcing steel bar 12 and the lower reinforcing steel bar 13 can be conveniently aligned. When the upper section reinforcing steel bar 12 and the lower section reinforcing steel bar 13 are two reinforcing steel bars with different diameters, because the chuck of the upper clamp 3 and the lower chuck 10 are the same structure, the central lines of the open ends of the upper clamp and the lower clamp are positioned on the same vertical section, the central lines of the reinforcing steel bars fixed by the upper clamp and the lower clamp are all positioned on the same vertical plane, and only the position of the lower section reinforcing steel bar 13 needs to be moved at this time, so that the central lines of the upper section reinforcing steel bar 12 and the lower section reinforcing steel bar 13 are positioned on the same straight line again. The position of the steel bar fixed by the upper clamp 3 is fixed, the lower clamp head 10 and the lower clamp base 7 of the lower clamp are of a movable connection structure, and the position of the steel bar clamped into the lower clamp head 10 can be horizontally adjusted by adjusting the position of the lower clamp head 10, so that the upper section of steel bar 12 and the lower section of steel bar 13 are conveniently centered.

The lower chuck 10 is connected with the lower chuck base 7 through the adjusting screw 9 and the positioning screw 11 to form a lower clamp, and the position of the lower chuck 10 in the horizontal direction is adjusted and positioned through the adjusting screw 9 and the positioning screw 11.

The adjusting screw rod 9 is in transition fit with the lower chuck 10 and is screwed with the lower chuck seat 7 through threads, and the threads are fine threads.

Go up 4 head ends of clamping screw and be the chuck with 3 integrated into one piece of last anchor clamps, this structure makes the reinforcing bar position of going up 3 fixed of anchor clamps unique, can not change, during the reinforcing bar of different diameters of butt joint, the rigidity of one of them reinforcing bar, this moment only need adjust the position of another reinforcing bar can, need not adjust two more positions simultaneously, it is more convenient to adjust.

The specific use method is as follows:

butt welding steel bars with the same diameter: and (3) putting the lower section of steel bar 13, screwing down the clamping screw 6 to clamp the lower section of steel bar 13, inserting the upper section of steel bar 12 into the chuck of the upper clamp 3, and screwing down the upper clamping screw 4. The adjusting screw 9 is tightened until the outer edge of the positioning screw 11 is aligned with the outer edge of the lower chuck 10. The flux box is then slipped on and flux is added for soldering (here the same as for conventional soldering, not described in detail). When the welding flux is melted, the rotating handle 2 applies downward pressure, and the downward pressure is sequentially transmitted to the upper section of the steel bar 12 through the gear box 1, the lifting screw 8 and the upper clamp 3, so that pressure welding is realized. After the welding is cooled, the upper clamping screw 4 of the upper clamp 3 is firstly loosened, then the pressure is released, and the operation sequence is strictly forbidden to be reversed.

Butt welding of the steel bars with different diameters: and (3) putting the lower section of steel bar 13, screwing down the clamping screw 6 to clamp the lower section of steel bar 13, inserting the upper section of steel bar 12 into the chuck of the upper clamp 3, and screwing down the upper clamping screw 4. The adjusting screw 9 is matched with the lower clamping screw 6 until the upper section steel bar and the lower section steel bar are aligned. The rest of the operation is the same as the first embodiment.

According to the device, the handle 2 is rotated to transmit force to the gear box 1, the gear box 2 further transmits the force to the lifting screw 8, and the gear and rack meshing of the gear box 1 and the lifting screw 8 transmits the movement to the upper clamp 3, so that the action of pressing down is realized.

The device fixes the steel bars through the upper clamping screw 4 and the upper clamp 3, so that the upper and lower sections of steel bars are subjected to pressure butt welding, and the symmetrical splayed shape ensures that the steel bars can be centered.

The utility model discloses a chuck is the built-up components under the device, comprises lower holder 7 and lower chuck 10 two parts, connects through positioning screw 11, adjusting screw 9, and the assembly relation is seen in figure 3. The positioning screw rod 11 is a countersunk head bolt, is in clearance fit with the chuck and is in threaded connection with the lower chuck seat 7, so that the adjustment of the lower chuck 10 can be ensured, and the lower chuck 10 can be fixed. The adjusting screw 9 is in clearance fit with the chuck and is connected with the lower clamping seat 7 through threads to play a role in adjusting and fixing. The lower clamping head 10 is in a symmetrical splayed shape and is assembled with the upper clamping head 3 in the same main view plane to realize the alignment of the steel bars in the top view plane, and the principle description is shown in figure 4.

The utility model discloses when 11 assemblies of device positioning screw let the screw rod outer along with lower chuck 10 when following the alignment outward, chuck 10 aligns with last anchor clamps 3 just down, and then makes the section aligns about with the diameter reinforcing bar, saves and aligns with the diameter reinforcing bar and uses adjusting screw 9, and the principle illustration picture is seen fig. 5.

The utility model discloses the device will strictly guarantee in assembling process that two symmetry "eight" font openings of going up anchor clamps 3 and lower chuck 10 strictly align on the face of looking down.
