Detailed Description

As shown in figure 1, the turnover clamping mechanism for welding the temperature sensor comprises a base 1, wherein lug plates are arranged on the left side and the right side of the front end of the base 1, a rotating shaft 2 is rotatably arranged between the two lug plates through a bearing, and a clamp 3 is fixed on the rotating shaft 2. One side of the rotating shaft 2 extends out of the lug plate and is fixedly connected with a first gear 4, and a rack 5 is meshed above the first gear 4. The rack 5 is longitudinally arranged, the rear part of the rack 5 is fixedly connected with the sliding seat 6, the sliding seat 6 is arranged on the sliding rail 7 in a sliding mode, and the sliding rail 7 is fixed on the base 1. In addition, a top rod 8 is connected with the tail part of the sliding seat 6, and a roller 10 is arranged at the upper end of the top rod 8. The ejector rod 8 is driven by the ejector mechanism to move back and forth.

When the ejector mechanism is not operated, the wire is held in a horizontal state by the gripper 3, as shown in fig. 6. When the ejector rod 8 moves forwards by the action of the ejection mechanism, the rack 5 also moves forwards, the first gear 4 rotates anticlockwise, and the clamp 3 rotates downwards to be in a vertical state, as shown in fig. 7. When the ejector rod 8 moves backwards by the action of the ejection mechanism, the rack 5 also moves backwards, the first gear 4 rotates clockwise, and the clamp 3 rotates upwards to be in a vertical state. Therefore, the wire can be vertically upward or downward, and is convenient to contact with tin liquid in a tin liquid groove below, so that tin dipping is realized.

A first spring 9 is connected between the sliding seat 6 and the tail part of the sliding rail 7. When the ejection mechanism is a reducing cam, the first spring 9 can enable the ejector rod 8 to be always attached to the cam.

As shown in fig. 2, the fixture 3 includes a base 3.1, a positioning block 3.2 is fixed at the bottom end of the base 3.1 through a connecting plate, two positioning pieces are fixedly arranged at the lower part of the front end of the positioning block 3.2 at intervals, a clamping plate 3.3 is arranged at the outer side of the two positioning pieces, a hinge shaft is fixed at the tail end of the two clamping plates 3.3, and the hinge shaft is rotatably connected with the base 3.1. A second gear 3.4 is fixed on each of the two articulated shafts, and the two second gears 3.4 are mutually meshed. In addition, the second spring 3.5 is connected between the two clamping plates 3.3 and on the side of the hinge axis. A roller 10 is arranged at the upper end of one of the clamping plates 3.3.

When the cylinder with the push plate pushes the roller 10 to move to one side, one clamping plate 3.3 rotates outwards around the axis of the hinge shaft, and then the gear 3.4 at the position of the clamping plate 3.3 is driven to rotate. The gear wheel 3.4 on the other side is also rotated synchronously, so that the other clamping plate 3.3, which is coaxially connected with the gear wheel 3.4 on the other side, is also rotated, as shown in fig. 4-5. Therefore, the two clamping plates 3.3 can be opened, and wires can enter between the clamping plates 3.3 and the positioning sheets conveniently. After the cylinder of later stage contracts, under the effect of second spring 3.5, two splint 3.3 laminating spacers to press from both sides the wire rod between splint 3.3, the spacers tightly.
