Problems solved by technology
The fixed clamping block and the movable clamping block are provided with matching positioning grooves, and the shaft is clamped into the positioning groove for grinding processing. However, due to the short circular shaft section of the concentric special-shaped shaft, the existing Clamping and positioning tooling is difficult to realize, therefore, it is necessary to design suitable clamping and positioning tooling according to the structural characteristics of concentric shaped shafts

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0017] A grinding tool suitable for concentric shaped shafts, please refer to figure 1 ‐3, the invention points are:
[0018] It includes an electromagnetic chuck 1, a tooling base 2, a fixed wedge 9 and a movable wedge 10. The fixed wedge and the movable wedge are respectively provided with an upper wedge surface and a lower wedge surface, and the inclination angles of the two wedge surfaces are consistent. The tooling base as a whole has a rectangular block structure, and two rows of positioning blind holes 3 are opened on the tooling base. Each row of positioning blind holes is composed of a plurality of positioning blind holes evenly arranged. The shapes of the special-shaped shaft sections of ...

The invention relates to a grinding tool suitable for concentric special-shaped shafts. The grinding tool comprises an electromagnetic suction cup, a tool base, a fixed wedge block and a movable wedgeblock. Two rows of locating blind holes with the shape consistent with that of a special-shaped shaft section are formed in the tool base, a jackscrew hole is formed in the outer side of each locating blind hole, and jackscrews are mounted in the jackscrew holes. The tool base is arranged above the electromagnetic suction cup through four vertical guide rails matched with four corners, and the four vertical guide rails are fixed to the electromagnetic suction cup in an attracted manner. The fixed wedge block is fixed to the upper portion of the electromagnetic suction cup in an attracted manner, the lower wedge face of the movable wedge block is in contact fit with the upper wedge face of the fixed wedge block, and the upper end face of the movable wedge block is in contact fit with the lower end of the tool base. A movable wedge block driving mechanism is further mounted on the electromagnetic suction cup and comprises an adjusting screw rod, the adjusting screw rod is connected witha screw rod support fixed above the electromagnetic suction cup in an attracted manner through a thread, and the end of the screw rod is in jacking contact with the end of the movable wedge block. According to the grinding tool, clamping and locating of the multiple shafts are achieved at the same time, and the shafts are machined and formed at a time.
Description
technical field [0001] The invention belongs to tooling for grinding shaft workpieces, and relates to special-shaped shaft grinding technology, in particular to a tooling for grinding concentric special-shaped shafts. Background technique [0002] Some special-shaped shaft parts are involved in automobile mold parts, which are composed of round shaft sections and special-shaped shaft sections. The special-shaped shaft section is a regular and symmetrical shape in cross section, such as a single cuboid shape, a combined structure of two cuboids, a combined shape of a cylinder and a cuboid, and the like. The center of the circular shaft section of this type of special-shaped shaft is set concentrically with the geometric center of the special-shaped shaft section, and the concentricity requirements are relatively high. In addition, some concentric special-shaped shafts have higher requirements on the length and dimension of the round shaft section. Usually, after finishing, ...
