Abstract
The utility model relates to a grinding device for arc edges of knives, which is mainly used for machining arc cutting edges of floating blades used in the shipbuilding industry and belongs to the technical field of shipbuilding equipment. The grinding device comprises a milling and indexing disc (5) provided with a grinding tooling, the tooling comprises a facing head (1) and a press plate (2), a floating blade (3) is disposed between the facing head (1) and the press plate (2), the facing head (1) is fixedly connected with the press plate (2), a mounting groove (1.1) is arranged on the facing head (1), the width of the mounting groove (1.1) is identical to that of the floating blade (3), the floating blade (3) is mounted in the mounting groove (1.1), certain inclination is reserved between the bottom of the mounting groove (1.1) and the bottom of the facing head (1), and the inclination is equal to a cutting relief angle of the floating blade (3). The grinding device for arc edges of knives sufficiently utilizes existing resources in fields, and is simple in structure and lower in cost.
Description
Technical field
The utility model relates to a kind of knife tool arc edging turning device, is mainly used in the processing with the floating blade arc edge that uses in the shipbuilding industry, belongs to the shipbuilding equipment technical field.
Background technology
In the production process of 53000T, 30000T ship, the screw bore hole processing of stroking of jackshaft and tailing axle, jackshaft and main frame connecting flange is the engineering of a key.Originally the floating blade used of bore hole is linear cutting edge, and cutting force is bigger in the process, and the working angles vibrations are more serious, the bore hole poor surface smoothness.A kind of grinding machine has appearred in existing market can be processed into circular arc with the floating blade cutting edge, thereby effectively reduces cutting force, reduces the vibrations of working angles, and the bore hole surface smoothness is good, but this device structure is complicated, and cost is too high.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of floating blade arc edging turning device is provided, and it is simple in structure, and cost is lower.
The purpose of the utility model is achieved in that a kind of floating blade arc edging turning device, is characterized in: it comprises that the milling calibration closes, and said milling calibration is shut grinding fixture is installed; Said frock comprises facing head and pressing plate; Be provided with floating blade between facing head and the pressing plate, be fixedly connected between facing head and the pressing plate, have a mounting groove on the said facing head; Mounting groove is identical with the floating blade width; Floating blade is installed in the mounting groove, and there are certain gradient in mounting groove bottom surface and facing head bottom surface, and this gradient equals the back angle of floating blade.
Compared with prior art, the beneficial effect of the utility model is:
A kind of floating blade arc edging of the utility model turning device, it is through designing a grinding fixture again, and the milling calibration that this frock is installed on existing equipment in the factory is shut; This device has made full use of an interior existing resource, and equipment investment is little, and apparatus structure is simple; Cost is low, and is simple to operate, can easily the floating blade cutting edge be processed as circular arc; Reduced cutting force greatly, reduced the vibrations that working angles produces, the bore hole surface smoothness is good.
Description of drawings
Fig. 1 is the principle schematic of the utility model floating blade arc edging turning device.
Wherein:
Facing head 1, mounting groove 1.1, pressing plate 2, floating blade 3, emery wheel 4, milling calibration close 5.
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of floating blade arc edging turning device, and it comprises that the milling calibration closes 5; Said milling calibration closes on 5 grinding fixture is installed, and said grinding fixture comprises facing head 1 and pressing plate 2, connects through bolt between facing head 1 and the pressing plate 2; Have a mounting groove 1.1 on the said facing head 1; Mounting groove 1.1 is wide with floating blade 3, and floating blade 3 is installed in the mounting groove 1.1, between facing head 1 and pressing plate 2; There are certain gradient in mounting groove 1.1 bottom surfaces and facing head 1 bottom surface, and this gradient equals the back angle of floating blade 3.
Add man-hour, only need shake dividing head handle facing head 1 just can 360 ° of rotations, therefore need only the cutting gyratory directions of blade front with respect to emery wheel 4, rotate facing head 1 simultaneously, so just can cutting edge be processed as circular arc.
Claims (1)
1. floating blade arc edging turning device is characterized in that: it comprises that the milling calibration closes (5), and said milling calibration closes on (5) grinding fixture is installed; Said frock comprises facing head (1) and pressing plate (2); Be provided with floating blade (3) between facing head (1) and the pressing plate (2), be fixedly connected between facing head (1) and the pressing plate (2), have a mounting groove (1.1) on the said facing head (1); Mounting groove (1.1) is identical with floating blade (3) width; Floating blade (3) is installed in the mounting groove (1.1), and there are certain gradient in mounting groove (1.1) bottom surface and facing head (1) bottom surface, and this gradient equals the back angle of floating blade (3).
