Abstract

The utility model discloses a rectangular aluminum plate turning fixture, belonging to the technical fields of machining and metal cutting and aiming to solve the problem that the requirement for the parallelism of two large planes of a relatively-thin rectangular aluminum plate is difficult to ensure because the two large planes are machined on a turning lathe. The fixture disclosed by the utility model comprises a flat nut, an inner hexagon screw and an auxiliary cushion block, wherein a circular bead hole is formed in the center of the auxiliary cushion block; the inner hexagon screw is in threaded connection with the flat nut after passing through the circular bead hole in the auxiliary cushion block; a clearance is left between the auxiliary cushion block and the flat nut; the two opposite surfaces of the auxiliary cushion block are planes; when the rectangular aluminum plate turning fixture works, the surface of the auxiliary cushion block, which is in contact with a rectangular aluminum plate, is provided with a plurality of hemispherical bulges. The rectangular aluminum plate turning fixture can be matched with a common lathe to turn the plane of the rectangular aluminum plate.

Description

A kind of rectangle aluminium sheet turning clamp
Technical field
The utility model relates to a kind of machining cutting jig, is specifically related to a kind of rectangle aluminium sheet turning clamp, belongs to machining metal cutting technology field.
Background technology
The square plate Shape Parts processing for the rectangle aluminium sheet that is 20mm by thickness, the first operation after blanking is two large planes of processing, conventional machining technique is to adopt planer processing.Planer processing characteristic is to have an impulse stroke, also has an inoperative backhaul, no matter is 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.Because the thickness of 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 to design an energy and support between chuck end face and the large plane of workpiece, fixing while being beneficial to workpiece to carry out turning.
Utility model content
The purpose of this utility model is that the rectangular plate aluminium sheet for solving thinner thickness is processed two large planes on lathe, is difficult to ensure the problem of two large plane parallelism requirements of sheet material, and then a kind of rectangle aluminium sheet turning clamp is provided.
The technical solution of the utility model 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, between auxiliary cushion block and jam nut, leave gap, two relative surfaces of described auxiliary cushion block are plane, and when work, auxiliary cushion block is provided with several hemispherical projections with the surface that described rectangle aluminium sheet contacts.
The utlity model has following beneficial effect: the utility model can ensure after two large plane turning of rectangle aluminium sheet, the depth of parallelism reaches 0.05mmm, by using the rectangle aluminium sheet that rectangle aluminium sheet turning clamp turning thickness of slab of the present utility model is 20mm, convenient and swift, production efficiency improves greatly.Originally one of processing approximately needs about 185 minutes, and processing now one approximately needs about 12 minutes, and production efficiency improves 9 times than original.Not only improve production efficiency, also saved mass energy, lathe motor is 7.5 kilowatts simultaneously, and planer motor is 20 kilowatts, the electric price of every degree is 1.20 yuan, and it is 185 ÷ 60 × 20 × 1.20-12 ÷ 60 × 7.5 × 1.20=72.20 units that electric energy is saved in one of so every processing.

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, between auxiliary cushion block 3 and jam nut 1, leave gap, two relative surfaces of described auxiliary cushion block 3 are plane, when work, auxiliary cushion block 3 is provided with several hemispherical projections 3-2 with the surface that described rectangle aluminium sheet contacts.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, to assist cushion block 3 to be fixed on chuck end face, workpiece is only abutted in to the upper surface of auxiliary cushion block, the screw rod of claw is controlled in rotation, by Workpiece clamping, start lathe turning workpiece, after first plane car is complete, by 180 ° of workpiece turnings, 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 utility model and chuck are used in conjunction with, and ensure to be exceeded by the machined surface of the rectangular plate aluminium sheet of card the highest plane of claw.When two large planes of rectangle aluminium sheet turning, need four rectangle aluminium sheet turning clamps of the present utility model to be arranged on the end face of chuck by the mode of being arranged symmetrically with.The thickness of slab of rectangle aluminium sheet is 20mm, and the thickness of jam nut 1 is 12.5mm.
