The two limiting blocks are oppositely clamped at the two ends of the relay, and opposite clamping grooves are machined in the opposite sides of the limiting blocks. According to the utility model, the driving assembly and the contact seat plate of the relay can be clamped and fixed through the clamp, and the distance required by the welding process can be maintained, so that the required time of the welding process is shortened, and the qualified rate of products is improved.

Description

TECHNICAL FIELD

[0001] The utility model relates to a relay drive assembly and seat plate welding fixture. BACKGROUND

[0002] As shown in Figure 3 and Figure 4 , the relay needs to be assembled and welded with the drive assembly and the contact seat plate assembly during the assembly process, and the distance between the drive assembly and the contact seat plate needs to be ensured during the welding process This size directly affects the assembly of the subsequent arc shield. If the size is too small, the arc shield cannot be installed, and if the size is too large, the arc shield cannot be clamped tightly and will be loose. The existing welding method controls the size after welding through the skill level of the welder, but since the parts are too small, the support plate is prone to deformation, and it is difficult for the worker to control the distance between the two support plates during spot welding; resulting in low production efficiency. As disclosed in CN211957548U, a four-way conversion balanced force type sealed mixed delay electromagnetic relay, the drive assembly and the contact seat plate in the relay are provided with mounting positions by the outer cover, and the relative position of the drive assembly and the contact seat plate is adjusted by providing a support plate in the drive assembly. But it will leave the support plate in the outer cover after welding, which will increase the weight, and each relay needs a support plate, which will increase the cost. SUMMARY

[0003] To solve the above technical problems, the utility model provides a relay drive assembly and seat plate welding fixture.

[0004] The utility model is realized through the following technical schemes.

[0005] The utility model provides a relay drive assembly and seat plate welding fixture, including fixed plate, limit block, clamping block, the fixed plate is fixed in the limit block upper end through the pin, the other end of pin stretches out limit block bottom and is slipped with clamping block, still be equipped with locking screw in the limit block, locking screw is once through fixed plate and limit block and is with clamping block screwing after, two limit blocks are opposite and are clamped at the both ends of relay, and the opposite side of limit block is processed with opposite clamping groove.

[0006] The opposite edges of the upper and lower ends of the limit block are processed with a limiting step.

[0007] The limiting step extends to the lower end of the edge of the fixed plate.

[0008] The edge of the clamping groove is also processed with a flared portion.

[0009] It also includes a fixing seat, and a square recess for accommodating the contact plate is processed on the fixing seat.

[0010] The relay driving assembly and the contact seat plate can be clamped and fixed through the clamp, the distance required by the welding process can be maintained, the required time of the welding process is shortened, and the qualified rate of products is improved.
