雙筋蹄組合機(jī)床的夾具設(shè)計(jì)
摘 要：夾具主要依據(jù)零件的加工要求來設(shè)計(jì)的。夾具應(yīng)滿足零件加工工序的精度要求、加工生產(chǎn)率要求，并保證操作方便、安全及使用壽命和較低的夾具制造成本。本課題加工的零件是焊接件，總體呈拱形，兩端分別有直徑為20mm和30mm的孔，拱形的外緣有一高為100mm的肋板。零件的加工精度要求較低。
根據(jù)六點(diǎn)定位原理和定位基準(zhǔn)的選擇原則，采用長(zhǎng)V型塊，支承塊和定位擋鐵定位。長(zhǎng)V型塊置于拱形肋板后限制x軸的兩自由度和z軸的兩自由度，擋鐵置于孔端限制繞y軸旋轉(zhuǎn)的自由度，支承塊置于肋板下方限制沿y軸移動(dòng)的自由度。依據(jù)相關(guān)原理計(jì)算定位誤差。根據(jù)夾緊方式的選擇原則選擇夾緊元件為壓板壓頭和V型塊，然后通過切削力進(jìn)行夾緊力的計(jì)算。夾緊的動(dòng)力裝置選用液壓裝置。按照定位元件和夾緊元件設(shè)計(jì)連接件。因?yàn)榈稐U較短，所以在本課題中導(dǎo)向元件設(shè)計(jì)就不作要求。然后進(jìn)行其它元件和裝置的設(shè)計(jì)。
根據(jù)以上元件和裝置確定夾具總體布局和夾具體的結(jié)構(gòu)形式，并處理好定位元件在夾具體上的位置。繪制夾具方案設(shè)計(jì)，進(jìn)行工序精度分析。對(duì)以上設(shè)計(jì)進(jìn)行審核。最后設(shè)計(jì)夾具總裝配圖。

The design of the jig of double rebars and feet of modular machine
Abstract: The jig design is based on the request of parts working . the jig should satisfy the request of mading procedure precision , the processing productivity, and guarantee ease of operation, security ,service life and low production cost. This parts are the weldment in this task, the whole parts with two holes lying in head and foot whose the diameter respectively are 20mm and the 30mm assume the arch, the arch outflow boundary has a ribbed plate whose height is the 100mm. The parts processing precision is low.
According to six localizations principles and selection principle of the localization datum, using the long V block, the supporting block and the localization comes true the hard localization. The long V block putted in the arch ribbed plate to limit two degrees of freedom in x axis and the z axes two degrees of freedom, the iron putted in the hole end limit to the degree of freedom which circle the y rotation of axis, the supporting block putted under the ribbed plate to limit degree of freedom along the y axis migration. position error is reckoned by the correlation principle . According to the way of the selection principle , discharge head and V block is selected to clamp the part .Then Computation of the strength is achieved by carrying on through the cutting force clamps . The power of clamps is from the hydraulic unit. Design of bridge piece is according to the location part and the clamp part. The guide part designing in this topic is not requested because the cutter bar is short. Other parts and equipment is designed following last process.
The jig overall arrargement and concrete structure of the body clamp is determined with the above part and the equipment. The position of the components in the kits specific location must be guaranteed ,and then design the jig , carry on the working procedure precision analysis. The design review is following. Finally the jig assembly drawing is achieved.
Keywords: jig ; location; clamp; modular machine tool.
