[0023] In order to further improve the clamping stability of the aluminum plate workpiece 14, that is, after the limiting clamping groove 10 on the side of the limiting clamping block 5 is in contact with the edge corner of the aluminum plate workpiece 14, the clamping pressure plate 1209 in the clamping positioning auxiliary component is extended forward, that is, the regulating screw 1206 is directly pushed by hand, and then the movable slider 1204 is pushed to slide in the guide groove until the positioning slot 1205 set on the movable slider 1204 is aligned with the threaded hole 1202 in the limiting frame plate 1201, and then the positioning screw 1203 is used to position the movable slider 1204. At the same time, the clamping pressure plate 1209 set at At the upper position of the edge corner of the aluminum plate workpiece 14; finally, the supporting main cylinder 3 and the supporting auxiliary cylinder 7 are started at the same time, so that the supporting main plate 4 and the supporting auxiliary plate 9 push up the aluminum plate workpiece 14 at the same time, until the top of the edge corner of the aluminum plate workpiece 14 contacts the cylindrical surface of the auxiliary pressure column 1302 at the bottom of the clamping pressure plate 1209, that is, the auxiliary pressure column 1302 cooperates with the supporting auxiliary plate 9 to press and clamp the aluminum plate workpiece 14 for positioning, wherein the clamping and positioning auxiliary components include a limit frame plate 1201, a threaded hole body 1202, a positioning screw 1203, a movable slider 1204, a positioning slot 1205, a regulating screw column 1206, an auxiliary pressure column 1302, and a positioning screw 1303. The handle head 1207, the second auxiliary bearing 1208, the clamping plate 1209 and the auxiliary structure; the limit frame plate 1201 is symmetrically arranged on the top of the limit clamp 5, and the limit frame plate 1201 is fixed by screws, and two groups are symmetrically arranged, and a threaded hole body 1202 is arranged on the top of the limit frame plate 1201, and the threaded hole body 1202 is threadedly connected with the positioning screw 1203 to form a guide groove between the two limit frame plates 1201; the movable slider 1204 is movably arranged in the guide groove, and the positioning card grooves 1205 are symmetrically arranged on both sides of the top of the movable slider 1204, and the positioning card grooves 1205 and the threaded hole body 1202 are threadedly connected. The two hole bodies 1202 are set in corresponding positions and the same number of groups, and the positioning slot 1205 is adapted to be clamped with the end of the positioning screw 1203; a regulating screw column 1206 is provided with a threaded connection through the movable slider 1204, and an auxiliary handle head 1207 is fixedly provided at one end of the regulating screw column 1206, and the other end of the regulating screw column 1206 is connected to the second auxiliary bearing 1208, and the second auxiliary bearing 1208 is embedded and fixedly provided at one end of the clamping pressure plate 1209; the clamping pressure plate 1209 is provided in the guide groove between the limit frame plates 1201, and the clamping pressure plate 1209 and the limit clamp block 5 are provided with the same number of groups.

[0024] When the aluminum plate workpiece 14 is supported by the supporting main plate 4 and the supporting sub-plate 9, it is used in conjunction with the clamping pressure plate 1209 to clamp the aluminum plate workpiece 14, wherein an auxiliary structure is provided on the bottom side of the clamping pressure plate 1209, that is, the auxiliary structure includes a supporting sheet 1301, an auxiliary pressure column 1302 and a connecting pin 1303; the supporting sheet 1301 is fixedly arranged at equal distances on both sides of the bottom end of the clamping pressure plate 1209, and the supporting sheet 1301 and the auxiliary pressure column 1302 are arranged by The auxiliary pressure column 1302 is set to be connected with the connecting pin 1303, and the auxiliary pressure column 1302 is set to roll, and the bottom cylindrical surface of the auxiliary pressure column 1302 is in contact with the top surface of the limiting clamp 5; when the aluminum plate processing part 14 is in contact with the bottom cylindrical surface of the auxiliary pressure column 1302, that is, the top surface of the aluminum plate processing part 14 is flush with the top surface of the limiting clamp 5, it can be ensured that when the top plane of the limiting clamp 5 is milled, the limiting clamp 5 used for limiting will not cause obstruction to it, thereby ensuring the smooth progress of the processing.

[0025] The cam 1206 is then turned to move the cam 1207 away from the workpiece 14 so that the workpiece 14 is not moved back. 09 retracts, that is, retracts toward the guide slot until the clamping plate 1209 does not affect the processing of the aluminum plate workpiece 14. At this time, some areas of the clamping plate 1209 can provide a limiting effect on the aluminum plate workpiece 14, which can avoid affecting the smooth progress of the processing while ensuring its processing quality, and has good working flexibility. In addition, the auxiliary pressure column 1302 provided at the bottom of the clamping plate 1209 in this scheme is intended to provide a protective effect for the aluminum plate workpiece 14, that is, when the clamping plate 1209 is controlled to move by adjusting the screw column 1206, the auxiliary pressure column 1302 rolls instead of sliding, thereby avoiding friction damage to the contact position of the aluminum plate workpiece 14.

[0026] Furthermore, when the clamping plate 1209 is in the process of processing the aluminum plate workpiece 14, if the clamping plate 1209 presses the entire area of ​​the aluminum plate workpiece 14 and causes an obstruction to the processing, it is necessary to separate the clamping plate 1209 from above the aluminum plate workpiece 14, that is, to retract the clamping plate 1209 into the guide slot, that is, to release the clamping limit work of the clamping plate 1209 on the aluminum plate workpiece 14 in the vertical direction. However, if the clamping plate 1209 is not used to provide a vertical limit to the aluminum plate workpiece 14, If there is no limit, the stability of the aluminum plate workpiece 14 during the processing cannot be well guaranteed. Therefore, during the processing, when the processing tool reaches the clamping pressure plate 1209 at a certain position, the clamping pressure plate 1209 at that position is separated from the aluminum plate workpiece 14, and the clamping pressure plates 1209 at other positions do not need to be moved. When the processing here is completed, the clamping pressure plate 1209 is quickly moved to the top of the corner of the aluminum plate workpiece 14 to limit it, which has good working flexibility and convenient operation.

[0027] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
