摘 要

長(zhǎng)久以來，對(duì)螺紋連接件的拆裝人們都用傳統(tǒng)的人力方法。其擰緊力的大小不易控制，精度不高，且勞動(dòng)強(qiáng)度大，效率低，成本高。針對(duì)這一現(xiàn)象，本課題設(shè)計(jì)的新型液壓機(jī)具——液壓緊固機(jī)，能隨意設(shè)定力矩值，保證連接的精度，有效地降低勞動(dòng)強(qiáng)度，提高工作效率。此機(jī)緊固與檢測(cè)一次完成，適用于絕大部分螺紋連接中預(yù)緊力的測(cè)量和控制?？梢詮V泛的應(yīng)用于電力、冶金、化工、煉油、鍋爐、礦山、造船、和鐵路等行業(yè)的大型設(shè)備的安裝和拆卸，尤其是對(duì)裝有易燃、易爆、劇毒的危險(xiǎn)設(shè)備的拆裝，液壓緊固機(jī)更是理想的選擇。它可以針對(duì)不同的材料和等級(jí)的螺栓施與材料允許的最大扭矩，從而保證螺栓、螺母在彈性變形的范圍內(nèi)可靠安全的工作，液壓緊固機(jī)采用了液壓系統(tǒng)回路來控制棘輪工作頭，同時(shí)工作頭可與不同規(guī)格的套筒配合使用，以滿足不同用戶的使用需求。

ABSTRACT

Over the years, people always use traditional human method to dismantle or install the screw thread link piece. The tightening of the size difficult to control, accuracy is not high, and labor intensity is great, low efficiency and high cost. In response to this phenomenon, the research design of new hydraulic equipment - hydraulic fastening machine, it can be arbitrarily set torque value, and ensure the accuracy of connection, to reduce labor intensity and enhance efficiency. This machine fastening and testing are once completed, apply to the vast majority of thread connecting preload the measurement and control. It can be widely used in electric power, metallurgical, chemical, oil refineries, boilers, mining, shipbuilding, and rail industries such as large-scale equipment, especially for containing flammable, explosive, poisonous the entry of dangerous equipment , Hydraulic fastening machine is the ideal choice. It can be for different levels of material and bolts of giving material to allow maximum torque to ensure that bolts, nuts elastic deformation in the context of a reliable safety, hydraulic retention of the hydraulic system used to control loop ratchet work First, the first at the same time work with different specifications can be used with the sleeve, to meet the needs of different users use.


Key words： Hydraulic fastening machine,wrench,whorl connection
