DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example

[0027] like Figure 1 A welding fixture shown in the figure comprises a fixture base 1 and a square steel right-angle plate 2. The fixture base 1 is in the shape of a right-angled triangle, and the two right-angled sides of the fixture base 1 are both composed of the square steel right-angled plates 2. A reinforcing plate 3 is connected between the vertical surfaces of the square steel right-angled plates 2 by welding, and a hand hole 4 is arranged inside the reinforcing plate 3. The square steel right-angled plates 2 on the right-angled sides of the fixture base 1 can be connected by the reinforcing plate 3, so as to achieve a supporting effect, thereby improving the load-bearing capacity of the square steel right-angled plates 2, and through the fixture base 1 The combination of the overall triangular structure and the reinforcing plate 3 ensures the overall stability of the clamp, thereby reducing the influence of external factors on the stability of the clamp itself. The setting of the handle hole 4 provides convenience for the use of the clamp. A first clamping plate 5 is embedded inside the outer surface of the square steel right-angle plate 2, and the first clamping plate 5 is rotatably connected to the square steel right-angle plate 2 through a first shaft rod 6 that runs through the inside of the square steel right-angle plate 2, and a threaded fixing block 7 is fixed at the end of the first shaft rod 6. The outer two right-angle sides of the clamp base 1 are connected with an adjustment mechanism 8;

[0028] like Figure 2As shown, the adjustment mechanism 8 includes a support plate 801, a rotating handle 802, a support plate 803, a second clamping plate 804, a limiting slide bar 805, a triangular notch 8061, an arc surface 8062, a second shaft 808, a handle 809 and an adjusting screw 807. The vertical part of the "L"-shaped support plate 801 is screwed to the clamp base 1 through a notch provided at the bottom end of the square steel-shaped right-angle plate 2, and the inner side surface of the horizontal part of the support plate 801 is fixedly connected to the rotating handle 802, and the bottom end of the rotating handle 802 is connected to the support plate 803, and the interior of the support plate 803 is provided with a notch provided at the bottom end of the square steel-shaped right-angle plate 2. The supporting plate 803 is slidably connected to the supporting plate 801 through the notch, the bottom surface of the supporting plate 803 is connected to the second clamping plate 804, and the second clamping plate 804 is connected to the supporting plate 803 with the arc-shaped sliding groove through the limiting sliding rod 805 set on one end surface of the second clamping plate 804, and the second shaft rod 808 penetrating the interior of the supporting plate 803 is provided at the center of the second clamping plate 804, and a screw sleeve is fixed at one end of the second shaft rod 808, and the second clamping plate 804 is connected to the supporting plate 801 through the second shaft rod 808. The second shaft 808 is rotatably connected to the support plate 803. A notch is provided at the top of the second shaft 808 and connected to the bottom end of the adjusting screw 807 which passes through the horizontal part of the support plate 801. An extrusion surface 806 is provided on the inner wall surface of the second clamping plate 804. The rotating handles 802 are symmetrical about the horizontal center line of the support plate 801. The support plate 803 forms a sliding structure with the support plate 801 through the rotating handle 802. The overall length of the rotating handle 802 is adjusted by rotating the rotating handle 802 itself, so that the support plate 803 can slide on the vertical part of the support plate 801, thereby adjusting the distance between the clamping plate and the platinum workpiece, thereby facilitating the clamping of the platinum workpiece. Two rotating handles 802 are provided and are respectively arranged on both sides of the symmetrical support plate 803. The number and position of the rotating handles 802 are set so that they can squeeze the two sides of the support plate 803 respectively, so that the two sides of the squeezing surface 806 can be in close contact with the platinum workpiece, thereby ensuring the stability between the platinum workpiece and the clamping plate, and further providing the possibility for accurate welding of the platinum workpiece. The squeezing surface 806 is composed of triangular notches 8061 and arc surfaces 8062 that are equidistant and cross-arranged, and the triangular notches 8061 are connected by concentric arc surfaces 8062. The arcuate surfaces 8062 are connected, and the diameters of the arcuate surfaces 8062 are all equal. The arrangement of the triangular notch 8061 inside the extrusion surface 806 and the arcuate surface 8062 enables the extrusion surface 806 to clamp and fix the platinum workpieces with rectangular and circular structures, thereby getting rid of the disadvantage that most existing clamps can only clamp and fix the platinum workpieces of the same type, thereby greatly improving the flexibility of the use of the clamp. The limiting slide bar 805 passes through the arcuate slide groove 812 and is provided with a locking nut 813 on the outer side of the support plate 803.The locking nut 813 is threadedly connected to the end of the limiting slide bar 805. The locking nut 813 and the limiting slide bar 805 are threadedly rotated to adjust the tightness between the support plate 803 and the second clamping plate 804, which plays an important role in the clamping and fixing of the welding workpiece and the subsequent angle adjustment. The second clamping plate 804 and the support plate 803 are limited by sliding between the limiting slide bar 805 and the arc-shaped slide groove 812, so as to assist the angle adjustment of the second clamping plate 804.

[0029] The specific application process of the above-mentioned welding clamp is as follows: when using, first place the platinum workpiece between the first clamping plate 5 and the second clamping plate 804, and place one side of the platinum workpiece close to the inner surface of the first clamping plate 5, and fix the second clamping plate 804 and the support plate 803 by rotating the thread between the locking nut 813 and the limiting slide bar 805, so as to facilitate the clamping of the welding workpiece, and then increase its own length by rotating the rotating handle 802. As its length increases, the support plate 803 slides downward in the vertical direction of the support plate 801, so that the second clamping plate 804 can squeeze the platinum workpiece inside it. After the platinum workpiece is fixed, the rotation of the rotating handle 802 can be stopped. The squeezing surface 806 of the second clamping plate 804 is composed of triangular notches 8061 and arc surfaces 8062 that are equidistant and cross-arranged. The arrangement of the triangular notches 8061 and the arc surfaces 8062 allows the squeezing surface 806 to squeeze the platinum workpiece with rectangular and circular structures. The parts are clamped and fixed, thereby expanding the scope of application of the clamp. Secondly, according to the need of clamping the platinum workpiece for welding, the support plate 803 and the second clamping plate 804 are fixed and released by rotating the threads between the locking nut 813 and the limiting slide bar 805, so as to facilitate the subsequent angle adjustment of the second clamping plate 804. Secondly, the second shaft rod 808 is driven to rotate by the rotation of the handle 809, so that the second clamping plate 804 can rotate on one side surface of the support plate 803, and the first clamping plate 5 By cooperating with the rotational connection between the square steel-shaped right-angle plate 2, the angle of the platinum workpiece clamped between the first clamping plate 5 and the second clamping plate 804 is adjusted, thereby providing a powerful condition for the multi-angle welding of the platinum workpiece. When the angle of the platinum workpiece is adjusted, the second clamping plate 804 and the support plate 803 can be limited by sliding between the limiting slide bar 805 and the arc-shaped slide groove 812, thereby assisting the angle adjustment work of the second clamping plate 804. After the angle adjustment is completed, the distance between the adjusting screw 807 and the top of the second shaft rod 808 is adjusted by rotating the screw thread of the adjusting screw 807 and the horizontal part of the support plate 801. When the bottom end of the adjusting screw 807 is embedded in the recess set inside the top of the second shaft rod 808, the second shaft rod 808 is positioned to fix the platinum workpiece after the angle adjustment, and finally the platinum workpiece can be welded.

[0030] When in use, the triangular structure of the clamp base 1 and its combination with the reinforcing plate 3 can improve the overall load-bearing capacity of the clamp, thereby reducing the impact of external factors on the stability of the clamp itself, thus completing the use of the clamp.
