The side plate clamping head is located below the workpiece jig. A gluing mechanism is arranged on one side of the workpiece placing mechanism. A side plate shearing mechanism is arranged beside the gluing mechanism. The whole machining process is fast and safe, manual operation is not needed, and the machining efficiency is greatly improved; and in addition, gluing is even, the phenomenon that glue inclines towards one side is avoided, gluing is firmer, and the appearance is more attractive.

The invention discloses a living hinge support type refrigerator door structure comprising a refrigerator body and a refrigerator door. The refrigerator door comprises a door body, the door body is rotatably connected with the refrigerator body through a first hinge, the lower end of the door body is connected with a lower trim strip, a first sliding positioning block is arranged on the lower endsurface of the door opening end of the lower trim strip, a hinge correcting assembly is arranged on the front end surface of the door opening end of the refrigerator body, and the lower trim strip isslidably connected to the hinge correcting assembly through the first sliding positioning block. A first wedge-shaped groove is formed in the rear end surface of the first sliding positioning block; and the hinge correcting assembly comprises a correcting fixing block, a correcting front supporting block and a correcting stand column, the correcting fixing block is fixedly connected with the refrigerator body, the correcting front supporting block is fixedly connected to the front end of the correcting fixing block, the correcting stand column is connected to the upper end of the correcting front supporting block, the correcting stand column is clamped into the first wedge-shaped groove and is connected with the first sliding positioning block. In the refrigerator door structure, through cooperation of the first sliding positioning block and the hinge correcting assembly, the problem of tilting of the door body is solved, and the structure is simple and novel.

The invention discloses a spot welding method for a vehicle suspension control arm. The spot welding method comprises the following steps of arranging a longitudinal adjustment plate on a base; arranging a transverse adjustment plate on the longitudinal adjustment plate; arranging a vertical support air cylinder on the transverse adjustment plate; arranging a suspension plate on the piston rod ofthe vertical support air cylinder; arranging a clamping arm I and a clamping arm II for tightly clamping a top cover and a bottom cover of the vehicle suspension control arm, on the suspension plate;connecting an electro-pneumatic proportional valve with the vertical support air cylinder for adjusting the air inflow of the vertical support air cylinder, so that when spot welding is performed eachtime, the whole body formed by the suspension plate, the clamping arm I, the clamping arm II and the vehicle suspension control arm is in a suspension state by adjusting the air inflow of the vertical support air cylinder through the electro-pneumatic proportional valve after a concave welding spot on the top cover and the bottom cover which are tightly clamped together moves to a location between an upper electrode and a lower electrode; and performing spot welding through the downward movement of the upper electrode.

An electronic device, such as a display. The electronic device includes an electronic device body, a support seat, at least one locking element and at least one protruding structure.
