Abstract

The invention provides a clamping and rotating device for machining the outer wall of a double-hole discharging sintered compact. The clamping and rotating device comprises a supporting table, a clamping assembly, a lifting assembly and a rotating assembly, wherein the clamping assembly comprises two pairs of adjusting components; each adjusting component is provided with an inward-extending component; an end clamping component is arranged between each pair of adjusting components; the adjusting component located at the upper end is provided with an inward-inserting component; the inward-extending components penetrate the inward-inserting components; the lifting assembly comprises a connecting component; the connecting component is installed on the end clamping component located at the upper end; the connecting component is provided with a guiding component; the guiding component is provided with a lifting component; and the lower end of the lifting component is installed on an installing base plate. The clamping and rotating device clamps and positions the outer wall of a double-hole discharging piece when machining the outer wall of the double-hole discharging piece, the double-hole discharging piece can be driven to rotate, the outer wall of the double-hole discharging piece can be machined conveniently through a machining device, the clamping and rotating device can be suitable for clamping double-hole discharging pieces of different sizes, excellent stability is achieved during clamping, the machining efficiency of the outer wall of the double-hole discharging piece is remarkably improved, and high practicability is achieved.

Description

technical field [0001] The invention relates to the related technical field of sintered compact processing equipment, in particular to a clamping and rotating device for processing the outer wall of a sintered compact with double-hole discharge. Background technique [0002] The casting and sintering method combines the characteristics of casting technology, powder metallurgy, and high-temperature self-propagation, and is mainly used to prepare metal matrix composites. Based on the traditional casting process, the composite material of the composite layer on the surface of the casting is crushed, and the composite compact is subjected to a high-temperature chemical reaction under the action of the high-temperature molten metal, and a large number of ceramic particles, TiC, VC, etc. are generated in situ. The occurrence of in-situ reaction makes the composite material layer have extremely superior performance, thereby prolonging the service life of the metal material. [000...

AI Technical Summary

Problems solved by technology

[0004] like Figure 18 It is a three-dimensional structure diagram of a double-hole discharge sintered compact obtained by casting and sintering. It can be seen from the figure that the double-hole discharge member 5 is symmetrically formed along the axial direction and has a pair of discharge holes 50. , after the casting and sintering of this double-hole discharge piece 5, there are often a large number of build-ups on the outer wall and the roughness of the outer arc wall is relatively large, but in the specific use process, the outer wall of the double-hole discharge piece 5 is rough The degree of precision needs to reach a certain level, and the existence of accumulated tumor etc. is inconvenient to carry out the assembly of this kind of double-hole discharging part 5 at the same time, so need to process its outer wall after finishing, and mainly exist inconvenient clip in the process of processing. and the existing device can only clamp the double-hole discharge part 5 of a specific size. The processing efficiency of material 5 has a serious impact
