Abstract
A kind of rectangle aluminium sheet turning clamp, belongs to machine metal cutting technology field, for two large planes processed by the rectangular plate aluminium sheet solving thinner thickness on lathe, is difficult to the problem ensureing the large plane parallelism requirement of sheet material two.Fixture of the present invention comprises jam nut, soket head cap screw and auxiliary cushion block, the center of described auxiliary cushion block is processed with shoulder hole, described soket head cap screw is connected with the screw of jam nut through the shoulder hole of auxiliary cushion block, assist and leave gap between cushion block and jam nut, the surface that two of described auxiliary cushion block are relative is plane, during work, the surface that auxiliary cushion block contacts with described rectangle aluminium sheet is provided with several hemispherical projections.The present invention and engine lathe support the use, for the turning of rectangle aluminium sheet plane.
Description
Technical field
The present invention relates to a kind of machining cutting jig, be specifically related to a kind of rectangle aluminium sheet turning clamp, belong to machine metal cutting technology field.
Background technology
For the square plate Shape Parts that the rectangle aluminium sheet by thickness being 20mm processes, the first operation after blanking is processing two large planes, and traditional machining processes adopts planer processing.Planer processing characteristic has an impulse stroke, and no matter also have an inoperative backhaul, be impulse stroke or inoperative backhaul, its feeding speed is all very slow, working (machining) efficiency is very low, in order to improve working (machining) efficiency, selects two large planes of lathe turning the party disk shape part.Thickness due to rectangle aluminium sheet (hereinafter referred to as workpiece) is 20mm, lower than the height dimension of chuck jaw, because the large plane of workpiece two has depth of parallelism requirement, and chuck jaw must use in anti-claw-like state, workpiece and chuck end face can not be reclined, therefore, need design energy to support between chuck end face and the large plane of workpiece, what be beneficial to when carrying out turning to workpiece is fixing.
Summary of the invention
Two large planes processed by the rectangular plate aluminium sheet that the object of the invention is for solving thinner thickness on lathe, are difficult to the problem ensureing the large plane parallelism requirement of sheet material two, and then provide a kind of rectangle aluminium sheet turning clamp.
Technical scheme of the present invention is:
A kind of rectangle aluminium sheet turning clamp, it comprises jam nut, soket head cap screw and auxiliary cushion block, the center of described auxiliary cushion block is processed with shoulder hole, described soket head cap screw is connected with the screw of jam nut through the shoulder hole of auxiliary cushion block, assist and leave gap between cushion block and jam nut, the surface that two of described auxiliary cushion block are relative is plane, and during work, the surface that auxiliary cushion block contacts with described rectangle aluminium sheet is provided with several hemispherical projections.
The present invention has following beneficial effect: after the present invention can ensure the large plane turning of rectangle aluminium sheet two, the depth of parallelism reaches 0.05mmm, the rectangle aluminium sheet turning clamp turning thickness of slab of the application of the invention is the rectangle aluminium sheet of 20mm, and convenient and swift, production efficiency improves greatly.Originally processing one approximately needs about 185 minutes, and processing one now approximately needs about 12 minutes, and production efficiency improves 9 times than original.Not only increase production efficiency, also save mass energy, lathe motor is 7.5 kilowatts simultaneously, and planer motor is 20 kilowatts, the price often spending electricity is 1.20 yuan, and so often processing a saving electric energy is 185 ÷ 60 × 20 × 1.20-12 ÷ 60 × 7.5 × 1.20=72.20 units.

Detailed description of the invention
As shown in Fig. 1 ~ Fig. 5, a kind of rectangle aluminium sheet turning clamp, it comprises jam nut 1, soket head cap screw 2 and auxiliary cushion block 3, the center of described auxiliary cushion block 3 is processed with shoulder hole 3-1, described soket head cap screw 2 is connected with the screw of jam nut 1 through the shoulder hole 3-1 of auxiliary cushion block 3, assist and leave gap between cushion block 3 and jam nut 1, the surface that two of described auxiliary cushion block 3 are relative is plane, during work, the surface that auxiliary cushion block 3 contacts with described rectangle aluminium sheet is provided with several hemispherical projections 3-2.The surface of described several hemispherical projections 3-2 is provided with anti-slip veins.The profile of jam nut 1 is rectangle, and the screwed hole of rectangle jam nut 1 is positioned at rectangle jam nut 1 center, and the two ends of rectangle jam nut 1 are arc-shaped convex end, are convenient to be arranged in the dovetail groove of chuck.Described rectangle aluminium sheet size: long 500mm, wide 450mm.
The course of work: first rectangle aluminium sheet turning clamp is arranged on chuck, jam nut 1 is arranged in the dovetail groove of chuck, soket head cap screw 2 is threaded with jam nut 1 through auxiliary cushion block 3, auxiliary cushion block 3 is fixed on chuck end face, workpiece is only abutted in the upper surface of auxiliary cushion block, rotate the screw rod controlling claw, by Workpiece clamping, start lathe turning workpiece, after first plane car is complete, by workpiece turning 180 °, repeat aforesaid operations, complete second plane of car, completes the turnery of a workpiece.
Four claws of rectangle aluminium sheet turning clamp of the present invention and chuck with the use of, ensure the highest plane being exceeded claw by the machined surface of the rectangular plate aluminium sheet of card.During rectangle aluminium sheet turning two large planes, four rectangle aluminium sheet turning clamps of the present invention are needed to be arranged on the end face of chuck by asymmetrical arrangement.The thickness of slab of rectangle aluminium sheet is 20mm, and the thickness of jam nut 1 is 12.5mm.
