[0002] In the process of chassis production, especially for military electronic chassis with high quality requirements, it is necessary to ensure the stability of its internal structure and surface quality. During the batch production of chassis, when a large number of chassis are transferred to the next process, a transfer device is needed to uniformly load the chassis and then transfer them to the next workshop.

[0003] During the transfer process, in order to increase the loading capacity of the transfer device, people often stack the chassis together for transfer. This is likely to cause damage due to mutual collision between the chassis, and such loading is also extremely unstable, and the chassis is likely to fall off the transfer device. Therefore, there is an urgent need to design a transfer device for batch production of chassis to solve the above problems. Summary of the Invention

Inside the transfer bracket, a longitudinal partition and multiple transverse partitions are fixedly connected. The longitudinal partition and the transverse partitions divide the internal area of the transfer bracket into multiple placement chambers. Horizontally arranged transverse movement guide rails are fixedly connected to both the top and bottom of the transfer bracket. On each transverse movement guide rail, a horizontally movable mounting seat with a lockable position is slidably connected through a slider.

When the extending end of the pressing box cylinder 8 ejects, it can press and clamp the chassis located in the placement chamber 21 downward, avoiding the chassis from shaking frequently during the transfer process.

[0035] Working process:

[0036] (1) First, the clamping cylinders in each clamping unit drive their corresponding clamping pressure plates to flip outwards by a certain angle to a preset position for clamping the side wall of the chassis; then, the two moving gantry frames 6 are respectively moved to both sides of the transfer bracket 5 to facilitate inserting multiple chassis into the respective placement chambers 21 one by one, and the positions of the chassis are adjusted so that the opposite side walls of two adjacent chassis in the horizontal position are in contact with the longitudinal partition 19; the longitudinal positions of each outer clamping device and inner clamping device are adjusted so that their longitudinal positions correspond to the positions of the chassis in the placement chamber 21;

[0037] (2) Synchronously start the clamping cylinders in the second inner clamping device 16 and the second outer clamping device 17, and the corresponding clamping pressure plates and the longitudinal partition 19 jointly act to clamp the opposite side walls of the two chassis;

[0038] (3) Move the above-mentioned moving gantry frame 6 along the transverse guide rail 4 so that the first inner clamping device 9 and the first outer clamping device 11 move to the positions where they can clamp the outer side walls of the chassis. At the same time, start the clamping cylinders in the first inner clamping device 9 and the first outer clamping device 11 so that the inner clamping pressure plate 9-1 and the outer clamping pressure plate 11-1 clamp the outer side walls of the chassis; at the same time, adjust the position of the inner support positioning plate 12-4 through the first inner support cylinder 12-1 and the second inner support cylinder 12-3 so that the inner support positioning plate 12-4 is engaged with the right angle of the inner cavity of the chassis, thereby positioning the chassis, and at the same time cooperate with the box pressing cylinder 8 to perform stable positioning and clamping on the chassis;

[0039] (4) After completing the above clamping and positioning operations, the transfer bracket 5 can be pushed to batch transfer multiple chassis to the destination, avoiding the electronic chassis from moving around when pushing the transfer bracket 5;

[0040] (5) After the transfer bracket 5 moves to the destination, start the clamping cylinders in the second inner clamping device 16 and the second outer clamping device 17 again, drive the corresponding clamping pressure plates to flip outwards by a certain angle to a preset position, thereby releasing their clamping operations on the chassis; then start the clamping cylinders in the first inner clamping device 9 and the first outer clamping device 11 again; drive the corresponding clamping pressure plates to flip outwards by a certain angle to a preset position, thereby releasing their clamping operations on the chassis; then drive the inner support positioning plate 12-4 to reset through the first inner support cylinder 12-1 and the second inner support cylinder 12-3, releasing the positioning of the chassis; then move the two moving gantry frames 6 to both sides of the transfer bracket 5 respectively to facilitate taking out the chassis; finally, start the box cylinder 8 to release the pressing operation on the chassis; at this time, the outer block device 22 can block the chassis from sliding out of the roller device 13;

[0041] (6) When it is necessary to take out the chassis in each placement chamber 21, it is necessary to press the tilted limit block 22-2, and then take out the corresponding chassis.
