Preferably, the described briquetting one side of oppressing processed cylinder sleeve is provided with several projections.Because adopt bar thick stick principle to transmit power, stressed easy inequality adopts the projection effect of can exerting all one's strength to be evenly distributed.
Preferably, also be provided with compressing tablet between described supporting base and the described briquetting, described compressing tablet is circular, and the internal diameter of described compressing tablet is not less than the interior Circular Aperture of processed cylinder sleeve and is not more than the external diameter of processed cylinder sleeve.Adopt the compressing tablet transition, the power of avoiding projection to transmit acts directly on the cylinder sleeve and makes cylinder sleeve produce deformation.
Preferably, described fulcrum connects the expansion link of adjustable length.The product degree of adjustable telescopic rod makes the height of fulcrum adjustable, thereby makes the adjusting of these anchor clamps more convenient, the clamping of applicable different length size cylinder sleeve.
Preferably, described expansion link adopts cylinder, hydraulic cylinder or mechanical-stretching bar.
Further, described pneumatic means available hydraulic device replaces.
It is clamping that the utility model adopts supporting base and briquetting that cylinder sleeve is carried out, and it is simple in structure, and is easy to operate; Adopt pneumatic means or hydraulic means as driving, it is controlled that its pressure is adjustable, and be provided with the compressing tablet of transition, avoids cylinder sleeve directly stressed and produce deformation, and the clamping processing precision of products is high; Adopt matched in clearance, clamping efficient is high, can also test to the quality of the last operation of product; Compressing tablet adopts the lever principle power transmission, and its fulcrum is located by expansion link, can make these anchor clamps be fit to the clamping of different length size cylinder sleeve.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
The below specifically describes embodiment of the present utility model.
As shown in Figure 1, cylinder sleeve half right boring inner circle anchor clamps, comprise the supporting base 1 that supports processed cylinder sleeve and the briquetting 2 of oppressing fixing processed cylinder sleeve, described supporting base 1 bearing-surface cave inward form cylinder-shaped, processed cylinder sleeve 5 is set in the supporting base 1, limited moving axially on processed cylinder sleeve 5 horizontal planes, the non-flange portion 51 of described supporting base 1 depressed part and processed cylinder sleeve 5 adopts matched in clearance, has greatly made things convenient for the loading and unloading of cylinder sleeve.Described briquetting 2 is located at described supporting base 1 top, and described briquetting 2 hollow outs have the through hole that is communicated with processed cylinder sleeve inner circle and boring cutter, and the one side that described briquetting is oppressed processed cylinder sleeve is provided with several projections, adopts projection to realize that the some contact effect of can exerting all one's strength is evenly distributed.One end of described briquetting 2 fixed connecting rod thick sticks 3, the other end vertical direction of described bar thick stick 3 connects the piston rod 41 of pneumatic means 4, the middle part of described bar thick stick 3 is provided with a fulcrum 31, and described bar thick stick 3 is at pneumatic means 4(or hydraulic means) driving under can be around described fulcrum 31 rotary oscillations.Described fulcrum 31 is hinged on the fixed mount by rotating shaft, and fixed mount is fixedly connected with the expansion link 32 of adjustable length, and described expansion link 32 can adopt cylinder, hydraulic cylinder or mechanical-stretching bar.The product degree of adjustable telescopic rod makes the height of fulcrum 31 adjustable, thereby makes the adjusting of these anchor clamps more convenient, the clamping of applicable different length size cylinder sleeve.
