Abstract

The utility model relates to a fixture for inner bore grooving, which includes a tool shank, wherein a taper shank is arranged at the tail end of the tool shank; the front end of the tool shank is sleeved with a guide sleeve; a slope groove is arranged at the lower part of the front end of the tool shank, where the guide sleeve is arranged; a square hole for mounting a tool bit is formed on the guide sleeve, and corresponds to the slope groove in position; the tool bit is in sliding contact with the slope groove; an a spring for elastically resetting the tool bit is arranged in the square hole. The fixture for inner bore grooving solves the problem that ordinary drilling machines and boring machines can not process grooves in a bore, thereby expanding the using range of the drilling machine, improving the processing efficiency, shortening the process time and meeting the production requirements.

Description

A kind of endoporus grooving anchor clamps

Technical field

The utility model relates to the Machining Technology field, concrete relate to a kind of in the internal control of part the frock clamp of working groove.

Background technology

Working groove in the hole of part all can't directly be processed with radial drill, vertical drill, boring machine, because radial drill, vertical drill can only axial feeds, radially feed, even on custom-designed special purpose machine tool, process this class groove, also can make the complex structure of special purpose machine tool a lot.So, instrument that must design specialized, could be on radial drill, vertical drill, the boring machine economic processing of finishing this class part.

The utility model content

Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of endoporus grooving anchor clamps are provided.On common radial drill, vertical drill or boring machine, after the processing of finishing the hole, change this kind dedicated tool anchor clamps, the processing of hole slot in can finishing continuously improves working (machining) efficiency, shortens process time, enlarge the function of use of radial drill, vertical drill and boring machine, guarantee crudy.

In order to address the above problem the technical solution of the utility model is such:

A kind of endoporus grooving anchor clamps, comprise a handle of a knife, the tail end of handle of a knife is a taper shank, the front end of handle of a knife is with a fairlead, fairlead position, front end bottom at handle of a knife is provided with a surface groove, be provided with a square hole that is used to install cutter head with the corresponding fairlead in surface groove position, the afterbody of cutter head and surface groove sliding-contact also are provided with a spring that makes the cutter head elastic reset in the square hole.

Described fairlead outside also is with a bearing that is used to prop up workpiece to be processed, and the bearing arranged outside has the bearing sheath, and the bearing sheath outside adopts a hold-down nut to fix.

A keyway is driven at the middle part of handle of a knife, is provided with a flat key in the keyway, has an elongated slot on the flat key, is provided with the fixing screw of flat key in the elongated slot.

The front end end of handle of a knife is provided with a gland, and described gland is fixed on handle of a knife front end end by a screw.

Beneficial effect, endoporus grooving anchor clamps described in the utility model, solved with common driller, boring machine can not be in the hole difficult problem of working groove, enlarged the scope of application of drilling machine, improved working (machining) efficiency, shorten process time, satisfied production requirement.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is the cross-sectional view of a kind of endoporus grooving anchor clamps described in the utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1

In the present embodiment, endoporus grooving anchor clamps are made up of handle of a knife 1, fairlead 2, bearing sheath 3, bearing 4, cutter head 5, back-moving spring 6, hold-down nut 7, flat key 8 and screw 9, gland 10, screw 11.

Concrete, handle of a knife 1 one ends are made taper shank, and the main shaft of taper shank and lathe is connected; The groove 12 that it is the inclined-plane that handle of a knife 1 other end is opened a bottom, cutter head 5 can be in the oblique slip in groove 12 the insides, and cutter head 5 is flexible up and down in the sliding process.Fairlead 2 is enclosed within the front end of handle of a knife 1, fairlead 2 and handle of a knife 1 are matched in clearance, square hole of fairlead 2 front ends processing, be used for installing cutter head 5, and at two grooves that are used for installing back-moving spring of square hole 5 position cars, be provided with back-moving spring 6 in the groove, cutter head 5 by after the inclined-plane compression, the inclined-plane returns cutter head 5 and resets under the effect of back-moving spring 6.There is external screw thread at fairlead 2 middle parts, cooperate with bearing sheath 3 and hold-down nut 7, are provided with a bearing 4 in the bearing sheath 3, and bearing 4 is used to prop up workpiece 13.Bearing sheath 3 links to each other with handle of a knife 1 by screw thread and can change position on handle of a knife 1, thereby changes the position of working groove on the workpiece 13.

A keyway is driven at the middle part of handle of a knife 1, is provided with a flat key 8 in the keyway, and flat key 8 is fixed on flat key on the handle of a knife 1 by screw 9.One elongated slot is arranged on the flat key 1, can change the fixed position of flat key 8, thereby adjust the distance that handle of a knife moves forward, change the depth of cut of cutter head 5.

In addition, the front end end of handle of a knife 1 is provided with a gland 10, and described gland 10 is fixed on handle of a knife 1 front end end by a screw 11.Gland 10 can prevent fairlead 2 slippage from the handle of a knife 1.

Use and operation principle

On boring machine, to be processed as example.Workpiece 13 is set level, the handle of a knife 1 of anchor clamps moves forward, fairlead 2 enters workpiece 13 endoporus, continue to move forward, when bearing 4 is run into workpiece 13, because frictional force is big between it, the rotating ring of bearing 4 stops operating, fairlead 2 also stops to move forward, and at this moment handle of a knife 1 is rotated further by flat key 8 drive fairleads 2, and handle of a knife 1 continues to move forward, groove 12 bottoms on the inclined-plane of handle of a knife 1 end promote cutter head 5 and outwards move, the processing of beginning groove, after the degree of depth that is worked into requirement, handle of a knife 1 halts and begins to retreat, under the effect of back-moving spring 6, make cutter head 5 withdraw from the groove of workpiece 13, gland 10 contacts fairleads 2 and drives fairlead 2 and together withdraws from workpiece then, finishes a fabrication cycles.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
