A fixing plate is fixed on the outer wall of one side of the top of the support base. Positioning structures are arranged inside both the fixing plate and the movable plate;

[0009] One ends of the positioning structures are rotatably connected to fixing structures respectively.

[0010] Preferably, fixing holes are evenly formed at the bottom of the support base, and the support base is in an "L" shape.

[0011] Preferably, the limiting structure includes a limiting seat fixed on the inner wall of one side of the support base on one side of the driving gear. An inner cavity is formed inside the limiting seat. A limiting pin penetrates through the inner cavity. A return spring is sleeved outside the limiting pin inside the inner cavity. A return plate is fixed on the outer wall of the limiting pin near one end of the adjustment structure.

[0012] Preferably, both ends of the limiting pin extend to the outside of the limiting seat. A first handle is fixed at one end of the limiting pin. The other end of the limiting pin is clamped with one side of the driving gear. The limiting pin and the return plate form a telescopic structure through the return spring.

[0013] Preferably, the central axis of the guide groove is collinear with the central axis of the transmission gear, and the transmission gear is meshed with the driving gear.

[0014] Preferably, one end of the transmission shaft passes through the support base and is fixedly connected with one end of the movable plate. One end of the connecting shaft is fixedly connected with one end of the movable plate. One side of the bearing abuts against the outer side wall of the guide groove.

[0015] Preferably, the positioning structure includes sliding grooves formed on both sides inside the fixing plate and the movable plate. Positioning seats are arranged inside the sliding grooves. First threaded rods are fixed at the bottom ends of the positioning seats. The bottom ends of the first threaded rods pass through the sliding grooves and are threadedly connected with third handles.

[0016] Preferably, the sliding grooves are in a "T" shape. The positioning seats are slidably connected with the fixing plate and the movable plate respectively through the sliding grooves. One ends of the third handles abut against one side of the fixing plate and the movable plate respectively.

[0017] Preferably, the fixing structure includes a fixing seat rotatably connected to one end of the positioning seat. A clamping plate is arranged on one side of the fixing seat. A second threaded rod penetrates through one side of the interior of the clamping plate. Guide rods penetrate through both sides of the second threaded rod inside the clamping plate. Rubber pads are fixed on the inner walls of the fixing seat and the clamping plate.

[0018] Preferably, one end of the guide rod is fixedly connected to one side of the fixing seat. The guide rod is slidably connected to the clamping plate.

A fourth handle is fixed to the other end of the second threaded rod.

[0019] The advantages of a single-person seat frame production positioning and welding device provided by the present invention are as follows:

[0020] By providing an adjusting structure, when the driving gear is rotated, the driving gear will drive the transmission gear to rotate. The transmission gear will drive the movable plate to rotate through the transmission shaft, changing the angle between the movable plate and the fixed plate. As a result, the angles of the parts fixed by the fixing structure on one side of the fixed plate and the movable plate are changed. Thus, the device can adjust the direction according to the radian and angle of the parts, facilitating the rapid positioning of the welding parts, realizing the function that the device is convenient for adjusting the support angle, and thereby improving the applicability of the single-person seat frame production positioning and welding device during use.

[0021] Furthermore, when the first handle is pulled, the first handle will drive the limit pin away from the driving gear. At this time, the driving gear can be rotated by the second handle. When the first handle is released, under the elastic force of the return spring, the return plate will drive the limit pin to move towards the driving gear, making one end of the limit pin engage with one side of the driving gear. The driving gear will be in a self-locking state, keeping the angle between the movable plate and the fixed plate fixed, thereby improving the stability of the single-person seat frame production positioning and welding device during use.

[0022] By providing a positioning structure, when the fixing seat is pushed, the fixing seat will drive the positioning seat to slide inside the sliding groove. According to the shape of the welding part, the fixing seat can be moved to an appropriate position on one side of the fixed plate and the movable plate. At this time, the third handle is rotated so that one side of the third handle abuts against one side of the fixed plate and the movable plate. Then, the positioning seat is fixedly connected to the fixed plate and the movable plate respectively, thus fixing the position of the fixing seat, realizing the function that the device is convenient for adjusting the fixed position, and thereby improving the convenience of the single-person seat frame production positioning and welding device during use.

[0023] Further, place the parts to be welded between the fixed seat and the clamping plate. The fixed seat is rotatably connected to the positioning seat. According to the shape of the parts, the angle of the fixed seat can be adjusted to increase the contact area between the fixed seat and the clamping plate when clamping the parts, making the parts fixed more firmly. Under the protection of the rubber pad, it is avoided that the surface of the parts is scratched and worn during clamping and fixing, thereby improving the safety of the single-person seat frame production positioning and welding equipment during use.
