Abstract
The invention discloses a tool for removing bottom burr of a deep blind hole, which comprises an outer guide sleeve (5); the outer guide sleeve (5) is internally sleeved with an inner guide sleeve (4); one end of the inner guide sleeve (4) extends out of the end face of the outer guide sleeve (5); the outer surface of the inner guide sleeve (4), positioned the in outer guide sleeve (5), is provided with a lug (5); a spring (8) is fixedly connected between the lug (3) and the inner wall of the outer guide sleeve (5); the inner guide sleeve (4) is internally sleeved with a core rod (6); one end of the core rod (6) is fixedly connected with a core rod head (7), and the other end of the core rod (6) is fixedly connected with a pin (2); and the pin (2) is fixedly connected with a blade (1). After the tool adopting the structure is in alignment with the deep blind hole, the core rod head is pushed to lead the blade at the end part of the core rod to extend into the bottom of the deep blind hole, and then, the burr can be removed by rotating the core rod head. The tool provided by the invention is simple in structure and easy to operate.
Description
Technical field
The present invention relates to a kind of instrument that removes dark blind hole bottom burr.
Background technology
Field of machining need to be carried out processing deep blind-hole to the metal needs part usually.Existing dark blind hole is adding man-hour, the secondary cutter of drill bit can't be processed the dead angle of dark blind hole bottom, so burr can be left in dark blind hole bottom, in order to remove burr, the common practice is to adopt reamer or milling cutter to carry out the secondary hinge to expand, secondary easily causes the center in hole to be beated than dilatation, thereby so that the machining accuracy in hole be affected.
Summary of the invention
The objective of the invention is to solve existing dark blind hole and can leave the problem of burr adding man-hour dark blind hole bottom.
The technical solution used in the present invention is: a kind of instrument that removes dark blind hole bottom burr, it comprises outer bush, be socketed with interior guide pin bushing in the described outer bush, one end of described interior guide pin bushing stretches out the end face of outer bush, the outer surface that described interior guide pin bushing is positioned at outer bush is provided with projection, be connected with spring between described projection and the outer bush inwall, be socketed with core bar in the described interior guide pin bushing, an end of described core bar is connected with pin head, the other end is connected with pin; Be connected with blade on the described pin.
The beneficial effect that the present invention adopts is: after having adopted this structure, after this instrument aimed at dark blind hole, promote pin head so that the blade of core bar end stretches into dark blind hole bottom, blade rotates the burr that pin head just can be removed dark blind hole bottom after stretching into dark blind hole bottom, and this tool construction is simple, easy operating.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
Shown in the figure: 1 blade, 2 pins, 3 projections, 4 interior guide pin bushings, 5 outer bush, 6 core bars, 7 pin heads, 8 springs.
The specific embodiment
Below in conjunction with Fig. 1, the present invention is described further.
As shown in Figure 1, a kind of instrument that removes dark blind hole bottom burr, it comprises outer bush 5,5 are socketed with interior guide pin bushing 4 in the described outer bush, one end of described interior guide pin bushing 4 stretches out the end face of outer bush 5, and the outer surface that described interior guide pin bushing 4 is positioned at outer bush 5 is provided with projection 3, is connected with spring 8 between described projection 3 and outer bush 5 inwalls, be socketed with core bar 6 in the described interior guide pin bushing 4, an end of described core bar 6 is connected with pin head 7, the other end is connected with pin 2; Be connected with blade 1 on the described pin 2.
The present invention in use, this instrument is aimed at dark blind hole, promote pin head 7, projection extrusion spring 8 in this moment on the guide pin bushing 4 so that, after core bar 6 stretches into dark blind hole bottom, rotate pin head 7 and remove burrs, remove and unclamp pin head 7 after finishing, spring 8 resets and pin head 7 is resetted and then blade withdraws from dark blind hole.
After having adopted this structure, after this instrument aimed at dark blind hole, promote pin head so that the blade of core bar end stretches into dark blind hole bottom, blade rotates the burr that pin head just can be removed dark blind hole bottom after stretching into dark blind hole bottom, and this tool construction is simple, easy operating.
Claims (1)
