Abstract
The utility model discloses a tool used for machining surfaces of eccentric cylinders at two ends of a square rack. The tool comprises a rack machining fixture. The rack machining fixture comprises two fixture bodies which are installed on a lathe chuck and a tail center frame respectively. A square hole is formed in each fixture body. The square rack can be installed in the square holes. A first positioning surface and a second positioning surface are arranged in each square hole. When the square rack is installed in the square holes, the square rack abuts against the first positioning surfaces and the second positioning surfaces in a supported mode. The distance from each first positioning surface and each second positioning surface to the center of the outer cylindrical surface of each fixture body is identical to the size of the center of the surfaces of the eccentric cylinders at the two ends of the square rack. The tool used for machining the surfaces of the eccentric cylinders at the two ends of the square rack has the advantages of being simple in structure, accurate in centering, convenient to clamp, easy to adjust, good in economy, stable in quality, and high in production efficiency.

Technical field
The utility model relates to a kind of machinery processing apparatus, relates in particular to a kind of frock for square tooth bar two ends eccentric cylinder Surface Machining.
Background technology
Tooth bar is shaped as square usually, uses with the roller gear pairing and forms the tooth bar transmission, transmits rectilinear motion.Install for the ease of tooth bar, guarantee the correct engagement position of tooth bar and roller gear, respectively there is a periphery that is used for installing the location at the tooth bar two ends, and the periphery center not necessarily overlaps with square tooth bar center.Periphery turning processing on lathe usually, because tooth bar is shaped as square, be not easy at lathe chuck and afterbody centre frame clamping, more be difficult to clamping and centering adjustment when periphery center and square tooth bar center off-centre, the periphery at tooth bar two ends can't turning processing on lathe.
Therefore, provide a kind of convenient mounting and clamping, centering accurately, to adjust the simple frock that is used for the off-centre operation cylinder processing of square tooth bar two ends be the technical problem that those skilled in the art need solution badly.
The utility model content
The purpose of this utility model provides a kind of frock for the processing of square tooth bar two ends off-centre operation cylinder.
To achieve these goals, the utility model provides a kind of frock for square tooth bar two ends eccentric cylinder Surface Machining, comprise the tooth bar clamp for machining, described tooth bar clamp for machining comprises two jig main bodies that are installed in respectively on lathe chuck and the afterbody centre frame, described jig main body is provided with the square opening that described square tooth bar can be installed, first locating surface and second locating surface are arranged in the described square opening, when described square tooth bar is installed in the described square opening, rest on described first locating surface and described second locating surface.
Preferably, described square opening is slightly larger than described square tooth bar.
Preferably, also comprise housing screw, described housing screw can be pressed on described square tooth bar in the described square opening.
Preferably, the quantity of the housing screw of each square opening configuration is two, and the position of these two housing screws is vertical mutually.
Preferably, described first locating surface and described second locating surface equate to distance and the described square tooth bar two ends eccentric cylinder centre of surface position dimension at described jig main body external cylindrical surface center.
Compared with prior art, the frock for square tooth bar two ends eccentric cylinder Surface Machining provided by the utility model arranges square opening in the jig main body by processing tool, makes square tooth bar to be put into jig main body, is convenient to clamping; Square opening is slightly larger than square tooth bar and makes and to leave the gap between the two, so that square tooth bar can conveniently be put into the square opening of jig main body, compresses by housing screw then, and is convenient and reliable; First locating surface and second locating surface equate to distance and the described square tooth bar two ends eccentric cylinder centre of surface position dimension at jig main body external cylindrical surface center, make that the eccentric cylinder centre of surface that square tooth bar two ends need process when square tooth bar was installed in the square opening of jig main body is coaxial with jig main body external cylindrical surface center, meet the requirements with square tooth bar two ends eccentric cylinder centre of surface position dimension and the tolerance that guarantees processing.Square tooth bar is installed and is clamped a wherein end eccentric cylinder surface of the square tooth bar of back elder generation processing, turns around to process square tooth bar other end eccentric cylinder surface after processing again.
Therefore, frock for square tooth bar two ends off-centre operation cylinder processing provided by the utility model has realized technical purpose that the periphery at tooth bar two ends is processed, and have simple in structure, centering accurately, convenient mounting and clamping, adjustment easily, good economy performance, steady quality, production efficiency advantages of higher.
Description of drawings
Fig. 1 is the structural representation after the square tooth bar of a kind of embodiment of the frock that is used for the off-centre operation cylinder processing of square tooth bar two ends that the utility model proposes compresses;
Fig. 2 is the structural representation of jig main body of a kind of embodiment of the frock that is used for the off-centre operation cylinder processing of square tooth bar two ends that the utility model proposes.
The specific embodiment
The purpose of this utility model provides a kind of frock for the processing of square tooth bar two ends off-centre operation cylinder.
In order to make those skilled in the art understand the technical solution of the utility model better; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
Please refer to Fig. 1 and Fig. 2, in one embodiment, a kind of frock for the processing of square tooth bar two ends off-centre operation cylinder provided by the utility model comprises the tooth bar clamp for machining, described tooth bar clamp for machining comprises jig main body 2, housing screw 1, housing screw 4, described identical two tooth bar clamp for machining main bodys 2 are installed in respectively on lathe chuck and the afterbody centre frame.Useful line cutting processing can be put the square opening of square tooth bar 3 on the described jig main body 2, the first locating surface A and the second locating surface B are arranged in the described square opening, after installing, square tooth bar 3 rests on locating surface A and the locating surface B, square opening is slightly larger than square tooth bar 2, make and leave appropriate gap in square opening and the square tooth bar 3, so that square tooth bar 3 is conveniently put into jig main body 2 square openings, compress with housing screw 1, housing screw 4 then; In the described square opening the first locating surface A and the second locating surface B to the distance at jig main body 2 external cylindrical surface centers by square tooth bar 3 two ends eccentric cylinder centre of surface position dimensions designs coaxial with jig main body 2 external cylindrical surface centers so that square tooth bar 3 is put into the eccentric cylinder centre of surface that square tooth bar 3 two ends, back need process in jig main bodies 2 square openings; Square tooth bar 3 is installed and is clamped a wherein end eccentric cylinder surface of the square tooth bar 3 of back elder generation processing, turns around to process square tooth bar 3 other end eccentric cylinder surfaces after processing again.
