Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a combined reverse taper and rounding tool and a machining equipment. Background Art

[0002] The machining of reverse taper surfaces has always been a bottleneck in the manufacturing industry. The main contradiction is reflected in the large variety and high cost of tools. There are many ways to machine reverse tapers, but in terms of machining efficiency and quality, special forming tools are generally used for reverse taper machining. Because the reverse taper degrees are different, the required tool specifications are also different. In this way, a taper tool is needed for machining each reverse taper surface. In recent years, with the increasing demand for personalized products in the manufacturing industry, many reverse taper surfaces with different degrees have appeared in product design. In order to complete product delivery with quality and quantity guaranteed, manufacturers need to purchase a variety of different types of taper tools. For example, if there are five reverse taper surfaces with different tapers, five reverse taper tools need to be purchased, which brings greater cost pressure to manufacturers. In addition, the outer fillets at the reverse taper surfaces are generally polished by fitters, which directly affects product quality and manufacturing efficiency. Summary of the Invention

Third, select the corresponding rectangular blade 32 and circular blade 22 and install them on the corresponding rounded cutter head 21 and inverted cone cutter head 31 in sequence. Then, install the above-mentioned rounded cutter head 21 and inverted cone cutter head 31 according to the requirements and specifications. Finally, screw in the positioning rod 04 and press it tightly. It can be used only after checking that there is no looseness. According to different degrees of inverted cones and different fillets, select the corresponding chamfering and inverted cone cutter heads. One tool can complete the processing of the inverted cone surface and the rounding (chamfering) of the top of the conical surface at one time, greatly saving the tool cost and increasing the manufacturing efficiency by more than 30%.
