Abstract
The utility model discloses an inner hole grinding tool for thin-walled parts. An elastic positioning sleeve is arranged in an inner hole of a positioning plate in an interference fit manner. The inner hole of the positioning plate is in interference fit with the elastic positioning sleeve. A ring groove is formed on the outer circumference of the elastic positioning sleeve, an oil cavity is arranged on the positioning plate and provided with an oil hole connected with the ring groove of the elastic positioning sleeve, a compression sleeve is arranged at the oil cavity of the positioning plate, a compression screw is arranged on the compression sleeve and connected with the oil cavity on the positioning plate, and the oil cavity is filled with hydraulic oil. The inner hole grinding tool can effectively prevent the clamping deformation of the thin-walled parts, the inner hole grinding precision of workpieces is greatly improved, the coaxiality of the inner hole and the excircle can reach over level 5, the inner hole grinding tool has a simple structure, is low in manufacturing cost and high in production efficiency, and is convenient to use, and the production cost can be lowered by more than one third.
Description
Technical field
The utility model relates to the device of a kind of machinery processing apparatus, particularly processing thin-walled part.
Background technology
Thin-walled parts is because wall is thin, yielding, and its clamping is a difficult problem always during machining; Particularly the high thin-walled parts of required precision at finishing step, adds man-hour like internal grinding; General direct clamping cylindrical, existing clamping device is complex structure not only, and clamping is difficult for; Have a strong impact on working (machining) efficiency, increased production cost.
The utility model content
The utility model aims to provide a kind of inner hole grinding frock of thin-walled parts, can guarantee the inner hole grinding precision preferably, and is easy to use, and production efficiency is high.
A kind of inner hole grinding frock of thin-walled parts is equipped with elastic locating sleeve in the positioning disk endoporus, positioning disk endoporus and elastic locating sleeve interference fit; Elastic locating sleeve has annular groove on excircle; Oil pocket is arranged on the positioning disk, and oil pocket has oilhole to link to each other with the annular groove of elastic locating sleeve, and the oil pocket place of positioning disk is equipped with clamping sleeve; There is clamping screw to link to each other on the clamping sleeve, hydraulic oil is arranged in the oil pocket with oil pocket on the positioning disk.
Further, on the said clamping screw O RunddichtringO is installed.
Further, there is screw to link to each other on the said positioning disk, screw is installed on the screw with the annular groove of elastic locating sleeve.
Further, said positioning disk is installed on the terminal pad.
The utility model can effectively solve the clamping distortion of thin-walled parts, improves the inner hole grinding precision of workpiece greatly, and endoporus and outer circles can reach more than 5 grades, and be simple in structure, and low cost of manufacture is easy to use, and production efficiency is high, can reduce production costs more than 1/3.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 looks sketch map for the left side of structure shown in Figure 1.
Among the figure: the 1-positioning disk, the 2-positioning sleeve, the 3-clamping sleeve, the 4-clamping screw, 5-oil is stifled, 6-hydraulic oil, 7-terminal pad, 8-screw.
The specific embodiment
Like Fig. 1, shown in 2, the inner hole grinding frock of the utility model thin-walled parts is equipped with elastic locating sleeve 2 with interference fit in positioning disk 1 endoporus; Elastic locating sleeve 2 has annular groove on excircle, elastic locating sleeve 2 is a thin-walled at the annular groove place, on the positioning disk 1 oil pocket is arranged; Oil pocket has oilhole to link to each other with the annular groove of elastic locating sleeve 2, and the oil pocket place of positioning disk 1 is equipped with clamping sleeve 3, has clamping screw 4 to link to each other with oil pocket on the positioning disk 1 on the clamping sleeve 3; Hydraulic oil 6 is arranged in the oil pocket; The O RunddichtringO is installed on the clamping screw 4, also has oil to block up 5 on the positioning disk 1, oil pocket is sealed.
Further, there is screw to link to each other on the positioning disk 1, screw 8 and copper sheet are installed on the screw, be used for the exhaust of oil pocket and put waste oil with the annular groove of elastic locating sleeve 2.
Further, positioning disk 1 is installed on the terminal pad 7, and terminal pad 7 is installed on the lathe.
During use, workpiece is packed in the positioning sleeve 2, rotatably compress screw rod 4 and exert pressure toward the interior hydraulic oil 6 of giving, hydraulic oil 6 compresses positioning sleeve 2 under pressure, and the annular groove place of positioning sleeve 2 is a thin-walled, under the oil pressure effect, deforms, and holds workpiece tightly.Because positioning sleeve 2 in circumferential homogeneous deformation, makes workpiece stressed even on circumference under the hydraulic oil effect, can not be out of shape.Thereby can improve machining accuracy, can improve more than the precision one-level, and convenient mounting and clamping, can shorten non-cutting time significantly, reduce production costs.
