Therefore, the fixture improves the production efficiency greatly.

Description

Holding appliance specially for milling machine

(1) technical field

The utility model relates to a kind of Holding appliance specially for milling machine.Be used for shipbuilding production hatch board annex and carry out groove processing chord ladder otic placode boring processing.Belong to and build the ship equipment technical field.

(2) background technology

In shipbuilding is produced, often there is large batch of hatch board annex need carry out groove processing.In the groove process, traditional method is to rely on shaping machine and T68 boring machine to finish, and the shaping machine process velocity is too slow, T68 boring machine processing and loading clamp trouble, therefore the efficient of these two kinds of processing methods is very low, per hour can only process one at most, can not satisfy production requirement at all.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of can enhance productivity greatly, accelerates the Holding appliance specially for milling machine of process velocity.

The purpose of this utility model is achieved in that a kind of Holding appliance specially for milling machine, comprise clamp body, be drilled with a plurality of screwed holes on the clamp body, alignment pin is installed on the screwed hole, the height of alignment pin is lower than the height of workpiece, also vertically is provided with to support and screw rod on clamp body, is set with pressing plate on support and the screw rod, be set with spring on the screw rod of pressing plate below, revolve on the screw rod of pressing plate top and be equipped with clamp nut.

The beneficial effects of the utility model are:

These anchor clamps are to make full use of that X53T vertical knee-type milling machine cutting speed is fast, cutting force is big, the special fixture of the comprehensive good rigidly of lathe, characteristics that efficient is high, and it has overcome the deficiency of boring machine and drilling machine.Improved production efficiency greatly, process velocity by original every shortened in one hour every ten minutes, guaranteed the manufacturing schedule requirement of shipbuilding.

(4) description of drawings

Fig. 1 is the structural representation of the utility model Holding appliance specially for milling machine.

Fig. 2 is that the A of Fig. 1 is to view.

Among the figure: clamp body 1, support 2, spring 3, clamp nut 4, screw rod 5, pressing plate 6, alignment pin 7, workpiece 8, machined surface 8.1.

(5) specific embodiment

Referring to Fig. 1～2, Holding appliance specially for milling machine comprises clamp body 1, and clamp body 1 is wide according to the open slot of the both sides of the mesa designs of X53T vertical knee-type milling machine and milling machine table, is convenient to the fixing of anchor clamps.Concrete shape according to workpiece on the clamp body 1 is drilled with 10 screwed holes, is used to install alignment pin 7, can be according to the size and different location and installation of workpiece, and the height of alignment pin is a little less than the height of workpiece 8.The clamping of workpiece also vertically is provided with support 2 and screw rod 5 on clamp body 1 for convenience, is set with pressing plate 6 on support 2 and the screw rod 5, is set with spring 3 on the screw rod 5 of pressing plate 6 belows, revolves on the screw rod 5 of pressing plate 6 tops to be equipped with clamp nut 4.

Earlier anchor clamps are hung in milling machine table during use, press workbench longitudinal axis calibration clamp, pressing clip concrete 1, press workpiece size, shape, alignment pin 7 is installed, workpiece 8 is hung on clamp body 1, alignment pin 7 location, the height of adjusting pressing plate 6 and supporting 2 with Work-sheet pressing, is convenient to carry out Milling Process by clamp nut 4.Only need unclamp clamp nut 4 when changing workpiece and under the effect of spring 3, lift voluntarily and remove pressing plate, can realize the replacing of workpiece.

After treating the one side process finishing, workpiece stands up, and adjusts the position of alignment pin, repeats the processing that said process can be finished the workpiece another side.
