Embodiment Construction
[0011] A worm 13 is placed horizontally in the middle of the base 1 of the transmission mechanism, and the drive motor 2 drives the worm 13 to rotate through the gear 21. There are 16 worm gears 11 distributed on both sides of the worm 13, and a clutch 8 is arranged above each worm gear 11. , the lower end of the driving main shaft 6 is connected with the clutch 8 and the worm wheel 11, the driving main shaft 6 is vertically supported on the base mounting plate 5 through the thrust bearing 14, the upper end of the driving main shaft 6 is connected with the punch screw 7, and the punch screw 7 Connect with the nut 15 at the bottom of the punch.
[0012] Described base mounting plate 5 is a strip shape, and its surface evenly has 32 step holes, base 1 periphery is provided with support plate 16, and the support bearing 17 of worm screw 13 two ends is installed on the base support plate 16.
[0013] Each worm wheel 11 is fixed on the lower end of the drive main shaft 6 through th...

The invention belongs to a sheet metal forming technology, and relates to a transmission mechanism for height adjustment and positioning of a multi-point flexible support. A worm is flatly arranged at the center position of a base of the transmission mechanism; 16 worm wheels are respectively distributed at the two sides of the worm, a clutch is respectively arranged above each worm wheel, the lower end of a main drive shaft is connected with the clutch and the worm wheels, the main drive shaft is vertically fixed at a mounting plate of the base by a bearing, the upper end of the main drive shaft is connected with a punch screw rod, and the punch screw rod is connected with a nut at the lower part of the punch. By adopting a modular structure, the transmission mechanism for height adjustment and positioning can be randomly assembled according to the size of parts and randomly adjusts shape and surface according to the shape and size of the parts, thus manual adjustment of the support height of the punch is unnecessary. The multi-shaft integrated installation is realized by the design of the shape adjustment unit base, thus achieving the modular manufacturing.
Description
technical field [0001] The invention belongs to sheet metal forming technology, and relates to a transmission mechanism for height adjustment and positioning of a multi-point flexible support body. Background technique [0002] In the usual support body height adjustment mechanism, the support rods that make up the curved surface of the multi-lattice mold are formed by support rods of different heights. There is a screw nut mechanism at the lower end of the support body, and each support rod is supported by a fixed height. , if you want to change the shape of the lattice surface, you must first take out the support body, and manually adjust the length of the screw to change the height of the support body. These support bodies are densely arranged in a box to support each other. When the height of the supported point needs to be changed, the height of these fixed-length supports will rely on manual replacement of fixed supports of different lengths, or manually adjust the hei...
