Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1: the embodiment discloses welding clamp with adjustable angle, including bottom plate 1, two outer splint 3, two inner splint 6, press from both sides tight head 5 and be used for the drive to press from both sides the gliding drive arrangement of tight head 5, bottom plate 1 is equipped with arc wall 12, outer splint 3 articulates in bottom plate 1 through articulated shaft 31, outer splint 3 still connects in arc wall 12 through adjusting screw 4, inner splint 6 includes one 61 and two 62 articulated connecting rods of fixed connection (the angle can not be adjusted) connecting rod, the other end of one 61 articulates in pressing from both sides tight head 5, but the other end (expansion end) of two 62 connecting rods slidable connection in the lateral part of pressing from both sides tight head 5.
The two outer clamping plates 3 and the two inner clamping plates 6 are symmetrically arranged by taking the axis of the screw rod 2 as the axis.
Specifically, the driving device comprises a screw rod 2 and a thread plate 11 connected to the bottom plate 1, the screw rod 2 is connected to the thread plate 11 through threads, and the end of the screw rod 2 is rotatably connected to the clamping head 5. The thread between the screw rod 2 and the thread plate 11 is preferably a rectangular thread with high transmission efficiency.
The connection mode of the screw rod 2 and the clamping head 5 is as follows: the end of the screw rod 2 is provided with a boss 22, the end of the clamping head 5 is provided with a groove matched with the boss 22, and the boss 22 is connected with the groove and used for realizing the rotation transmission of the screw rod and the boss 22.
The specific structure that the movable end of the second connecting rod 62 can be slidably connected to the side part of the clamping head 5 is as follows: an extension part 51 is further arranged on the side part of the clamping head 5, the extension part 51 is connected to the jackscrew 7 through threads, the jackscrew 7 is parallel to the screw rod 2, and the end part of the jackscrew 7 is connected to the movable end of the second connecting rod 62. In order to enable the movable end of the second connecting rod 62 to be closely attached to the side part of the clamping head 5, a tension spring 8 is further arranged between the first connecting rod 61 and the second connecting rod 62 in the embodiment.
To facilitate rotation of the screw 2, a handle 21 is also provided at the end of the screw 2.
During the use, two rectangle dotted line frames in figure 1 represent two steel pipes of treating the welding, according to the contained angle adjustment angle between two steel pipes between two outer splint 3, the adjustment mode is, with outer splint 3 with articulated shaft 31 as the certain angle of axle center rotation, after angular adjustment is accomplished, fastening adjusting screw 4, with outer splint 3 locking on bottom plate 1, still be equipped with the scale at the lateral part of arc wall 12, can read the angle between two outer splint 3 through the scale that sets up at arc wall 12 lateral part.
