Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing:
[0014] Depend on Figure 1 to Figure 3 As shown, an accessory clamping mechanism for a vertical turning and milling machining center includes a clamping body 1, which is fixed below the ram 10 by screws. The clamping body 1 is square, and its shape is the same as that of the ram. Consistently, the positioning cone 4 is fixed inside the clamping body 1 through the cone surface, and the taper of the cone surface between the two is 7:24. Clamping cylinders 2 are symmetrically arranged on the four corners of the clamping body 1, and the pistons of each clamping cylinder 2 protrude toward the center, and the ends of the pistons are pushed against the grooves on the outer surface of the positioning cone 4, Simultaneously, the piston end surface and the bottom surface of the groove are also fitted with inclined planes. Each clamping oil cylinder 2 is connected with a detection s...

The invention provides an accessory clamping mechanism for a vertical turn-milling center. The accessory clamping mechanism mainly solves the problems that an existing accessory clamping device for the vertical turn-milling center is high in price, single in size and high in requirement for precision of installed parts. The accessory clamping mechanism is characterized in that clamping oil cylinders (2) are symmetrically arranged on the four corners of a clamping body (1), a locating cone (4) is fixed into the clamping body (1) through the conical face, pistons of the clamping oil cylinders (2) abut against a groove in the outer surface of the locating cone (4), the bottom of the locating cone (4) is connected with a cutter clamp (8), a cone handle (7) is connected to the upper portion ofthe cutter clamp (8), a pulling nail (6) is fixed to the upper portion of the cone handle (7), and the pulling nail (6) is matched with a pulling claw (11) in a main shaft (5). The accessory clampingmechanism for the vertical turn-milling center is simple in structure, convenient to operate, applicable to accessories of different sizes, low in requirement for machining precision of related parts,and low in manufacturing cost.
Description
technical field [0001] The invention relates to the field of machine tools, in particular to an accessory clamping mechanism for a vertical turning and milling machining center. Background technique [0002] At present, when the machine tool of the vertical turning-milling compound machining center automatically replaces the turning and milling accessories, it is necessary to set up a set of automatic clamping and loosening mechanisms between the machine tool ram and the accessories to realize the turning and milling accessories in the tool. Automatic replacement in the library. At present, the clamping device for the attachment of the vertical turning-milling compound machining center is expensive, the size is single, and the processing accuracy of the related parts installed is relatively high. Contents of the invention [0003] In order to overcome the disadvantages of the existing clamping device for attachments of vertical turning and milling machining centers, which...
