Description
Technical Field
The invention relates to a cutter for scraping a countersunk hole on the back of a machine body.
Background
The compressor organism is the casting member, box part, and the partial mounting hole of organism needs the back counter bore of processing hole, because the position is narrow and small or interfere, and partial counter bore can't be followed the front and processed, need the reverse back of the body to scrape the shaping.
Disclosure of Invention
The invention aims to provide a tool for scraping a counter bore on the back of a machine body, which can finish the processing of the counter bore in a narrow space or an interference processing position.
In order to solve the above problems, the technical solution to be solved by the present invention is:
a cutter for scraping a countersunk hole on the back of a machine body comprises a cutter bar and a cutter head, wherein the cutter bar comprises a handle part, a rod part and an insert rod, the cutter head comprises a cutter body and a blade, the middle part of the cutter body is provided with a jack matched with the insert rod, one end of the insert rod is provided with a waist-shaped plug, and two cambered surfaces of one end, close to the insert rod, of the plug are provided with inclined surfaces inclined to the plane of the plug; one end of the jack is provided with a waist-shaped clamping hole matched with the plug.
The surface of the rod part is provided with a plurality of chip grooves which are uniformly distributed around the axis of the rod part.
The invention has the beneficial effects that: the tool is easy to operate, can realize reverse processing, and can finish the processing of the countersunk hole at the narrow and small interference part of the machine body.

figure 6 is a front view of the cutting head of the present invention,
fig. 7 is a schematic cross-sectional view at C-C in fig. 6.
In the figure: the tool comprises a tool bar 1, a handle 11, a chip groove 12, a rod part 13, a plug 14, a bevel 15, an insert rod 16, a tool bit 2, a blade 21, a tool body 22 and a clamping hole 23.
Detailed Description
As shown in fig. 1 to 7, a cutter for scraping a countersunk hole on the back of a machine body comprises a cutter bar 1 and a cutter head 2, wherein the cutter bar 1 comprises a handle part 11, a rod part 13 and an insert rod 16, the rod part 13 is in clearance fit with the machined hole and is used as a positioning rod for machining the countersunk hole to ensure the coaxiality of the countersunk hole and the machined hole, the cutter head 2 comprises a cutter body 22 and a blade 21, the cutter head 2 is made of 45# steel, the blade 21 is YG 6D 125, the blade 21 is welded with the cutter head 2, the middle part of the cutter body 22 is provided with a jack matched with the insert rod 16, one end of the insert rod 16 is provided with a kidney-shaped plug 14, and two arc surfaces at one end of the plug 14 close to the insert rod 16 are provided with inclined planes 15 inclined to the plane of the plug 14; one end of the jack is provided with a waist-shaped clamping hole 23 matched with the plug 14.
When processing organism counter bore, pass the guide arm and wait to process the hole, then install tool bit 2 on inserted bar 16, 2 angles of rotatory tool bit let waist shape card hole 23 bulge edge paste tight inclined plane 15, make it block into the recess in to lock tool bit 2, tool bit 2 just can't drop from plug 14 like this, realize the lathe from this to the processing of the back of counter bore, after finishing processing, rotate 2 angles of tool bit, let plug 14 to its card hole 23, in order to dismantle tool bit 2.
The surface of the rod part 13 is provided with a plurality of chip grooves 12, and the chip grooves 12 are uniformly distributed around the axis of the rod part 13. This structure is used for discharging the scraped iron pieces.
