摘 要

夾具設(shè)計(jì)是機(jī)械制造廠里的一種工藝裝備，有機(jī)床夾具，焊接夾具，裝配夾具，檢驗(yàn)夾具等，一般的機(jī)床夾具是作為機(jī)床的輔助機(jī)構(gòu)設(shè)計(jì)的，而組合機(jī)床夾具是作為機(jī)床的主要組成部分，其設(shè)計(jì)工作是整個(gè)組合機(jī)床設(shè)計(jì)的重要部分之一。組合機(jī)床夾具應(yīng)便于實(shí)現(xiàn)定位和夾壓的自動(dòng)化，并有動(dòng)作完成的檢查信號(hào)。夾具體在機(jī)床上的安裝都是通過夾具體上的安裝基面與機(jī)床上的相應(yīng)表面的接觸或配合實(shí)現(xiàn)的。當(dāng)夾具體在機(jī)床工作臺(tái)上安裝時(shí)，夾具的重心應(yīng)盡量低，重心越高則支承面應(yīng)力越大，夾具底面四邊應(yīng)凸出，使其接觸良好，或底部設(shè)置四個(gè)支腳。當(dāng)夾具體在機(jī)床主軸上安裝時(shí)，夾具安裝基面與主軸相應(yīng)表面應(yīng)有足夠的配合精度，并保證安裝穩(wěn)定可靠。

Abstract
Tongs design is a kind of craft that machine manufactory in equip, organism bed tongs, welding tongs, assemble tongs, examination tongs etc., the general machine bed tongs is an assistance to be used as the machine bed organization design of, but the combination machine bed tongs is an importance to be used as the machine bed to constitute the part primarily, its design work is whole combination machine bed design part of a. Combination the machine bed tongs shoulds be easy to realize fixed position with clip the automation that press, also the check signal that action complete. The tongs all passes in the machine the gearing on the bed what tongs the gearing on realizes with superficial contact in the cowgirl on the bed in machine or matches.When the tongs installs in the machine bed work on the stage, the center of gravity of the tongs should be as far as possible low, center of gravity the more high an accepts should the dint is more big, the tongs bottom four directions should bulge, make its contact good, or the bottom establishes four a feets.When the tongs installs on the machine bed principal axis, the tongs install the to should have the enough match accuracy with principal axis cowgirl surface, and guarantee the gearing the stability dependable.



Keywords: tongs combination the machine bed clip the automation
