As shown in fig. 1-4, the utility model provides a technical solution: spot welding location frock of relay movable contact spring subassembly, including centre gripping chassis 2, centre gripping chassis 2 includes the bottom plate, and bottom plate one side fixedly connected with spacing curb plate 201, spacing curb plate 201 one side fixedly connected with vertical removal slide bar 202, vertical removal slide bar 202 one end fixedly connected with fixed centre gripping wall 106. In this example, the two sets of vertically moving slide bars 202 are located on two sides of the bottom plate, and the two sets of vertically moving slide bars 202 are different in length, because the fixed clamping wall 106 is disposed at one corner of the bottom plate, and is composed of two vertically disposed clamping wall bodies 1101, the edge of the bottom plate is not completely shielded, therefore, only one set of the two sets of vertically moving slide bars 202 is fixedly connected with the fixed clamping wall 106, the other set of the vertically moving slide bars is fixedly connected with the fixed clamping plate 204, and the other end of the fixed clamping plate 204 is fixedly connected with the other end of the bottom plate, and a series of communicating clamping grooves are uniformly formed in the two sets of vertically moving slide bars 202. The surface of the vertical moving slide bar 202 is movably connected with a vertical slide box 203, a transverse moving slide bar 205 is movably connected between the vertical slide boxes 203, in the embodiment, the inside of the vertical slide box 203 is provided with a slide bar storage roller, the transverse moving slide bar 205 is made of elastic metal strips which can be bent and wound, the metal strips can be wound on the slide bar storage roller and can be folded and unfolded along with the rotation of the slide bar storage roller, a rotating shaft is arranged on the vertical slide box 203, the slide bar storage roller can be rotated outside the slide box body, the transverse moving slide bar 205 is completely tightened and fixed, and therefore the movable clamping wall 101 cannot shake. One side of the transverse moving slide 205 is fixedly connected with the movable clamping wall 101, the movable clamping wall 101 comprises a clamping wall body 1101, and a rotating connecting frame 1102 is arranged inside the clamping wall body 1101. In this embodiment, the movable chuck wall 101 is constructed similarly to the fixed chuck wall 106, except that two chuck walls 1101 of the movable chuck wall 101 are separated from each other and are movably connected together by a rotating connecting frame 1102. Therefore, the angle in the middle of the movable clamping wall 101 is not fixed, and the side of the movable clamping wall, which is not connected with the transverse moving slide 205, can be opened to a certain angle, so that the relay can be conveniently placed in the movable clamping wall. A buffer slot is arranged on one side of the clamping wall body 1101, a buffer spring 1105 is fixedly connected on one side of the clamping wall body 1101, and a buffer clamping block 1106 is fixedly connected on one end of the buffer spring 1105. When the relay is placed between the fixed and

movable clamping walls

106 and 101, the movement of the movable clamping wall 101 on the vertically and horizontally moving

slide bars

202 and 205, and the rotation of the rotating link 1102 are finally constrained to the periphery of the relay. The buffer spring 1105 and the buffer clamp block 1106 prevent the movable clamp wall 101 from running too fast and breaking the relay. It is to be noted that a spacer is provided at the junction of the fixed clamping wall 106 and the vertically moving slide 202, also in order to protect the vertically sliding box 203.

Clamping wall body 1101 one end fixedly connected with sliding support 1103, sliding support 1103 inboard swing joint has flexible fixed knot 1104, and flexible fixed knot 1104 both sides have been seted up flexible notch, flexible fixed knot 1104 both sides fixedly connected with expanding spring, the flexible fixed tooth of expanding spring one end fixedly connected with. After the flexible fixing buckle 1104 is pushed out, the communicating clamping grooves formed in the fixing clamping plate 204 are inserted, the sizes of the communicating clamping grooves are close to those of the flexible fixing buckle 1104, and the inclined surface is arranged on one side, close to the fixing clamping plate 204, of the flexible fixing teeth, so that the flexible fixing teeth can be easily extruded to pass through the communicating clamping grooves, the rear sides of the flexible fixing teeth are straight, the flexible fixing teeth are difficult to penetrate through the communicating clamping grooves again under the action of external force, the angle control over the movable clamping wall 101 is achieved, and the relay is perfectly fixed. Because of the arrangement of the buffer spring 1105, the retractable fixing buckle 1104 can complete the fixing buckle even if it has a certain deviation with the communicating slot. Meanwhile, the top end of the rotary connecting frame 1102 is movably connected with an anode rotating arm, the top end of the anode rotating arm is movably connected with an anode moving table 108, and the top end of the anode moving table 108 is fixedly connected with an anode connecting plate 102. The top end of the fixed clamping wall 106 is fixedly connected with a negative rotating platform 107, and the top end of the negative rotating platform 107 is movably connected with a negative rotating arm 105. The top end of the negative rotating arm 105 is movably connected with a negative moving platform 104, and the top end of the negative moving platform 104 is fixedly connected with a negative connecting plate 103. In this embodiment, because the rotary connection frame 1102 is disposed in the movable clamping wall 101 so that the highest point of the movable clamping wall 101 is higher than that of the fixed clamping wall 106, the negative rotary platform 107 is disposed at the top end of the fixed clamping wall 106 as compensation, so that the two heights are consistent. The positive and negative

rotating arms

105 and 105 are identical in structure, and the length of the arms is set so that the movable clamping wall 101 and the fixed clamping wall 106 can still partially overlap when the arms are farthest away, the negative moving table 104 and the positive moving table 108 are pushed to the overlapping portion, the portions to be welded on the relay are fixed through the electrode connecting plates on the two moving tables, and spot welding operation is performed.

When this utility model is to be used, at first, the movable holding wall 101 is pulled away from the fixed holding wall 106, then the relay body to be spot-welded is put on the bottom plate and attached to the fixed holding wall 106, and then the movable holding wall 101 is pulled to be close to the other two sides of the relay, and the position of the movable holding wall 101 is fixed by the retractable fixing button 1104, thereby completely fixing the relay. Then, the positive rotating arm and the negative rotating arm 105 are rotated to surround the part of the upper surface of the relay needing to be welded, and the position of the part is positioned by the positive moving platform 108 and the negative moving platform 104, so that the electrode connecting plate connected with the part is conveniently connected with a spot welding system to carry out spot welding operation.
