Embodiment approach

[0055] We first set the anti-scraper in the closed state, see attached figure 1 , the transposition component is in the upper position. There are 24 low keys on the push plate, 12 high keys on the turntable, and 12 shallow key grooves and 12 deep key grooves arranged alternately on the push plate guide assembly. In the upper position, the 24 low keys of the push plate are embedded in the 24 key slots of the push plate guide assembly, while the 12 high rigid points of the turntable are in the inclined slots above the shallow key slots.

[0056] Pass the anti-scraper through the hole to be processed, and give the connecting plate an upward thrust at the hole, so that the connecting plate, push plate, ferrule, and sliding sleeve are connected together upward, so that the push plate pushes the turntable in the push plate guide assembly Move inward toward the cutter body, when the apex of the second key tooth on the turntable reaches the transposition point A, the original support...

Abstract

The invention discloses a reverse scraping tool for machining a reverse step hole. The reverse scraping tool comprises a tool body, a reverse scraping tool bit assembly and a transposition assembly. The reverse scraping tool bit assembly comprises a tool apron and a sliding sleeve matched with the outer side wall of the tool apron, the tool apron is provided with a groove capable of containing a reverse scraping tool bit, the reverse scraping tool bit is arranged in the groove in the manner that the reverse scraping tool bit can overturn in the preset direction and stretch out of the groove, and the sliding sleeve is provided with an opening for the reverse scraping tool bit to stretch out in the sliding process of the sliding sleeve. The transposition assembly is arranged between the tool body and the reverse scraping tool bit assembly so as to drive the sliding sleeve to slide along the preset track to achieve state switchover for the tool bit to stretch out of the groove, and accordingly, the tool bit assembly can smoothly penetrate a to-be-machined hole in the machining process. According to the reverse scraping tool for machining the reverse step hole, the machining auxiliary time can be effectively shortened, and the production efficiency is improved; and operation risks are reduced, and the effects that the implementation effect is good, the safety coefficient is high, operation difficulty is low, and the production efficiency is effectively improved are achieved.

Description

technical field [0001] The invention relates to a counter scraper for use in machining situations. More specifically, the present invention relates to a back scraper for back stepped hole machining used in the case of machining. Background technique [0002] At present, for the reverse scraping of the hole, most of them use the method of separating the scraper rod and the scraper head. When using it, pass the scraper rod through the bottom hole of the workpiece, and then install the cutter head and blade to process the reverse sink hole. After processing The cutter head is taken off, and the scraper rod is withdrawn from the bottom hole. [0003] The main disadvantages of the current solution include: first, the processing efficiency is low, and the tool head must be clamped and disassembled for each hole processed, and the auxiliary working time is too long, which affects the processing efficiency; second, some workpieces are relatively high, and the clamping and disassemb...
