Detailed Description
Referring to the attached drawings 1-3, the special tool for one-time clamping of each working procedure of machining the upper locking plate comprises a left fixing plate 1, a right fixing plate 2, a transverse plate 3, support blocks, a left pressing block 4, a middle pressing block 5 and a right pressing block 6, wherein the middle of the left fixing plate 1 is connected with the middle of the right fixing plate 2 through the transverse plate 3, two support blocks are uniformly designed on the transverse plate 3, one support block is a left support block 8, the other support block is a right support block 9, a left pressing block 4 is designed between the left support block 8 and the left fixing plate 1, the middle pressing block 5 is designed between the left support block 8 and the right support block 9, the right pressing block 6 is designed between the right support block 9 and the right fixing plate 2, the left pressing block 4, the middle pressing block 5 and the right pressing block 6 are all fixed on the transverse plate 3 through a screw rod and a nut, the lower end of the screw rod is fixed on the transverse plate 3, through holes are respectively designed among the left pressing block 4, A middle briquetting 5 and a right briquetting 6. The mounting surface of the upper lock piece workpiece is an arc surface, and the transverse plate 3 is correspondingly mounted on the left fixing plate 1 and the right fixing plate 2 at the same height on both sides.
The upper surface of the supporting block is designed according to the lower profile structure of the upper locking plate.
The left fixing plate 1 is fixed on a chuck 10 of a tailstock of a milling machine machining center, and the right fixing plate 2 is fixed on a chuck 11 of a rotation center of the milling machine machining center. The chuck 10 on the tailstock is rotatably arranged on the tailstock through a bearing.
When the utility model is used, the flaky blank is placed on the left supporting block and the right supporting block, the molded surfaces of the left supporting block and the right supporting block are the same as the molded surfaces of the lower surfaces of the flaky blank, so that the flaky blank is stably placed, then the flaky blank is respectively pressed on the left end and the right end of the flaky blank through the left pressing block and the right pressing block and is locked through the nut screw rod, and the middle pressing block, the screw rod and the nut at the middle position are disassembled; after the locking plate is fixed, the middle waist-shaped hole of the upper locking plate is milled in the first step, after the waist-shaped hole is machined, the screw rod penetrates through the waist-shaped hole to be fixed on the transverse plate, the middle pressing plate is pressed on the blank of the upper locking plate, the middle pressing plate is locked through the nut in the figure 3, then the left pressing plate, the screw rod and the nut are detached, the left side corner of the blank of the upper locking plate is milled, meanwhile, the front corner and the rear corner of the blank of the upper locking plate can be milled, finally, the left pressing plate is installed to compress the sheet blank, the right pressing plate, the screw rod and the nut are detached, the right side corner of the blank of the upper locking plate is machined, machining is completed, all pressing plates are detached, finished products are taken down, and a new.
