Abstract
The utility model relates to a tool for rapidly digging a groove in a workpiece hole, which comprises a Morse taper shank tool bar, a blocking device, a tool bit and a nut, wherein the blocking device comprises a bearing box, a pressing sleeve, a spring and a pressing block, wherein the bearing box comprises a bearing inner sleeve, a bearing, a bearing block and a bearing cap; the front end of the Morse taper shank tool bar is sheathed with the bearing box; the bearing in the bearing box is compressed by the bearing cap, the pressing sleeve and the spring sheathed on the pressing sleeve; the pressing sleeve is compressed and fixed by the pressing block; the tool bit is accommodated in the bearing inner sleeve; the bearing inner sleeve is fixed by the nut and a gasket on the Morse taper shank tool bar; the tool bit comes into contact with an inclined guide push rod at the front end of the Morse taper shank tool bar; and the rear end of the Morse taper shank tool bar is connected with a drill press spindle. The tool is used on a drill press. By adopting the tool for digging the groove, the positioning precision of digging the groove in the workpiece hole is high, the groove can be rapidly dug, the production efficiency is high and the labor strength of workers is greatly reduced.
Description
Technical field
The utility model relate to a kind of in the hole of workpiece the instrument of ditching groove.
Background technology
Have on a lot of machine components need be in the hole ditching groove.Existing method is in the lathe system of getting on the bus, and the rut groove is difficult for the location in workpiece hole, and also not easy to operate, not only working strength of workers is big, and machining accuracy is poor, and production efficiency is low.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, provide a kind of in workpiece hole the quick instrument of ditching groove, adopt the instrument of this ditching groove, ditching groove positional accuracy height in workpiece hole, rapidly, the production efficiency height.
For addressing the above problem, technical solution of the present utility model is: a kind of in workpiece hole the quick instrument of ditching groove, it comprises Morse taper shank knife bar, gear device, cutter head and nut; The gear device comprises bearing box, gland, spring and the briquetting of being made up of bearing inner sleeve, bearing, bearing block and bearing cap; Morse taper shank knife bar leading section is with bearing box, and the bearing in the bearing box is by bearing cap, gland and be enclosed within spring compression on the gland, and briquetting is fixed gland again; Cutter head is contained in the bearing inner sleeve, and bearing inner sleeve is by nut on the Morse taper shank knife bar and spacers, and cutter head contacts with the oblique guiding push rod of Morse taper shank knife bar front end; Morse taper shank knife bar rear end is connected with drill press spindle.
When using the utility model, at first adjust mutual alignment between Morse taper shank knife bar and gland according to the axial location of institute's grooving.Then cutter head is installed on the knife bar, start drill press spindle, rotate the slowly feeding of drilling machine feeding handle, when the end face G of bearing block face leans against on the end face of workpiece, just realized the axial location of knife bar, thereby determined the axial location of institute's grooving, cutter head moves radially along the oblique guiding push rod on the Morse taper shank knife bar, realize radially rising cutter, incision gradually is up to digging out needed groove.The utility model uses on drilling machine.Adopt the instrument of ditching groove of the present utility model, ditching groove positional accuracy height in workpiece hole, the ditching groove is rapid, and the production efficiency height has greatly alleviated working strength of workers.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, present embodiment comprises Morse taper shank knife bar 8, gear device, cutter head 9 and nut 11.The gear device comprises angular contact bearing box, gland 4, spring 2 and the briquetting of being made up of bearing inner sleeve 6, angular contact bearing 1, bearing block 7 and bearing cap 53.Morse taper shank knife bar 8 leading sections are with the angular contact bearing box, and the angular contact bearing 1 in the angular contact bearing box is compressed by bearing cap 5, gland 4 and the spring 2 that is enclosed within on the gland 4, and briquetting 3 is fixed gland 4 again.Cutter head 9 is contained in the bearing inner sleeve 6, and bearing inner sleeve 6 is fixing by nut on the Morse taper shank knife bar 8 11 and pad 10, and cutter head 9 contacts with the oblique guiding push rod 12 of Morse taper shank knife bar 8 front ends.Morse taper shank knife bar 8 rear ends are connected with drill press spindle.The G face is the end face of bearing block.
Angular contact bearing in the present embodiment is deep groove ball bearing also, and the angular contact bearing box is the deep groove ball bearing box.
