Description
Technical Field
The utility model relates to a frock clamp, especially a cylindrical piston part terminal surface processing frock.
Background
Each part in the piston is a core part of the engine, the machining quality of each part directly influences the service life and the safety of the engine, and therefore the dimensional quality precision of the parts is strictly controlled in the machining process of the parts. The piston is provided with a cylindrical component, the end face of the cylindrical component needs to be machined, conventionally, the piston is directly clamped by a three-jaw chuck on a machine tool during the end face machining of the component, the clamping precision of the mode is relatively low, the machining quality of the piston depends heavily on operations such as alignment control of an operator, and the like, namely, the influence of human factors is large. Moreover, long time is consumed for clamping and adjusting, and the working efficiency is relatively low. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can realize the cylindrical piston part terminal surface processing frock of clamping operation fast, accurately.
The technical solution of the utility model is that: the utility model provides a cylindrical piston part facing (operation) frock which characterized in that: the frock include main location axle 1, the one end of main location axle 1 is provided with ring flange 2, the center department of ring flange 2 is provided with toper connecting hole 3, and the periphery department of ring flange 2 still is provided with a plurality of screw holes 4 of evenly distributed on the circumferencial direction simultaneously, the other end of main location axle 1 then is provided with bottom plate 5, the longitudinal section of bottom plate 5 is semi-circular, with the bottom plate 5 matches be provided with top board 6, the longitudinal section of top board 6 is also semi-circular, bottom plate 5 and top board 6 are through two pairs of symmetric distribution's clamp bolt 7 interconnect, then are provided with a pair of clamp bolt 8 in the center department of top board 6, still be provided with locating pin 9 on the bottom plate 5.
Two symmetrically distributed copper semi-rings 11 are arranged in the inner side surface of the lower supporting plate 5, and two symmetrically distributed copper semi-rings 11 are also arranged in the inner side surface of the upper pressing plate 6.
Compared with the prior art, the utility model, have following advantage:
this kind of structural style's cylindrical piston part terminal surface processing frock, its simple structure, design benefit, it is rationally distributed, it is to various problems that traditional cylindrical piston part locate mode exists, a special structure has been designed, it designs one can with the location axle of lathe main shaft connection, be provided with the clamp plate of a pair of semicircle form on this location axle, these two clamp plates can press from both sides tightly the piston, and utilize the locating pin to carry out the ascending location of circumferencial direction and spacing to it, this kind of frock can be fast, accurately fix a position and press from both sides tightly the piston, in order to make things convenient for operating personnel to carry out the processing operation to the terminal surface of piston. The tool has the advantages of improving the working efficiency in the machining process of the end face of the piston part, effectively ensuring the machining precision, along with simple manufacturing process and low manufacturing cost, so that the tool has various advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.

Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: the utility model provides a cylindrical piston part terminal surface processing frock, the frock include main location axle 1, the one end of main location axle 1 is provided with ring flange 2, the center department of ring flange 2 is provided with toper connecting hole 3, and the periphery department of ring flange 2 still is provided with a plurality of screw holes 4 of evenly distributed on the circumferencial direction simultaneously, the other end of main location axle 1 then is provided with bottom plate 5, the longitudinal section of bottom plate 5 is semi-circular, with what bottom plate 5 matches is provided with top board 6, the longitudinal section of top board 6 is also semi-circular, bottom plate 5 and top board 6 are through two pairs of symmetric distribution's clamp bolt 7 interconnect, then are provided with a pair of clamp bolt 8 in the center department of top board 6, still be provided with locating pin 9 on bottom plate 5.
Two symmetrically distributed copper semi-rings 11 are arranged in the inner side surface of the lower supporting plate 5, and two symmetrically distributed copper semi-rings 11 are also arranged in the inner side surface of the upper pressing plate 6.
The working process of the cylindrical piston component end face machining tool with the structure form is as follows: firstly, a piston component 10 needing end face machining operation is placed on a lower supporting plate 5, a positioning pin 9 on the lower supporting plate 5 is inserted into a positioning hole in the piston component 10, and the positioning pin 9 can play a role in positioning and limiting, so that the piston component 10 is limited in the circumferential direction, then an upper pressure plate 6 is buckled above the lower supporting plate 5, the upper pressure plate 6 and the lower supporting plate 5 are fixed into an integral structure by using a clamping bolt 7, then the pressing bolts 8 are screwed, the bottom ends of the two pressing bolts 8 are pressed against the piston component 10, and the piston component 10 is clamped tightly, and in a clamping state, copper semi-rings 11 in the lower supporting plate 5 and the upper pressure plate 6 are directly contacted with the outer wall of the piston component 10, and the outer surface of the piston component 10 can be effectively protected because copper is relatively soft; after the operation is finished, the main positioning shaft 1 is fixedly connected with the machine tool spindle by utilizing the tapered connecting hole 3 and the plurality of threaded holes 4 on the flange plate 2, then the machine tool is started, the machine tool spindle drives the tool and the piston part 10 clamped on the tool to rotate at a constant speed, and an operator can machine the end face, protruding out of the device, of the piston part 10.
