[0002] When the refrigerator door body is processed, the positioning work frock is needed to fix the refrigerator door body, which is convenient for processing the refrigerator door body. The positioning frock can quickly and accurately position the door body on the processing equipment, reducing the time for manual alignment and adjustment and improving the processing efficiency. At the same time, due to the accurate positioning, the waste rate in the processing process is reduced, and the time and material waste caused by rework or scrap are also reduced.

[0003] The existing patent No. CN214323175U discloses a positioning frock for refrigerator door body assembly, which comprises a bottom plate, a supporting plate, a support, a counterweight, a motor, a fixed plate, a sliding plate, a clamping block, a screw rod, and a rotating seat. The motor drives the screw rod to rotate and drives the sliding plate to move, thereby adjusting the positioning width. It can meet the clamping of different width plates and the installation and disassembly of the positioning door. A limiting plate is arranged on one side of the supporting plate close to the sliding plate. The sliding plate can abut on the limiting plate under the driving of the screw rod to prevent the door from being squeezed or collided due to excessive movement distance. To ensure the stability of the sliding plate, oil injection holes are arranged on both sides of the sliding plate to facilitate the lubrication of the connection between the sliding plate and the screw rod, ensuring the stability of the rotation.

[0004] The above device fixes the refrigerator door body by using the pressing part. Since the length of the clamping plate is large, the processing operation of the door body may be disturbed during the fixing process. At the same time, the spacing between the two groups of clamping plates is not convenient to adjust, which leads to the fact that the length of the clamping plate easily affects the processing efficiency and precision when fixing refrigerator door plates of different sizes. In view of the above problems, the positioning work frock for refrigerator door body processing is proposed. UTILITY MODEL CONTENTS
