Abstract
The utility model relates to a tool for processing the groove in holes, comprising a tool shank and an outer case fixedly connected with the tool shank, which is characterized in that a device with an eccentric shaft of the cutter holder is arranged in the outer case, a mandrel is arranged in an eccentric hole of the eccentric cutter holder shaft for synchronous rotation with the eccentric cutter holder shaft, a cutter head is fixedly arranged on the mandrel end; a spiral guide groove is arranged on the outer case, a roller wheel is arranged on the eccentric cutter holder shaft and the roller wheel is right arranged in the guide groove; a compression locating device is arranged on the excircle surface of the eccentric cutter holder shaft out of the outer case; a spring is arranged between the eccentric cutter holder shaft and the outer case. The utility model has the advantages that the special tool can be arranged on the main shaft of the vertical drill based on the novel design and simple structure, which can realize the feeding in radial direction through the eccentric device when the main shaft of the vertical drill is in rotation motion and feed motion in axial direction and can reach the purpose of meeting the processing requirements with convenient operation.
Description
Technical field
The utility model relates to the machine-building category, especially a kind of in can machining hole groove, also can be used for the instrument of the anti-machining hole inside groove of scraping of hole inner face.
Background technology
We know that cost efficiency is the vital task of business administration.Enterprise only improves constantly technological level, could develop in intense market competition.Counter the scraping all of general hole inside groove or hole bottom face processed on lathe or boring machine, but also work in-process is processed in the heart.For some part, there is the clamping difficulty in processing on horizontal machine tool, and efficient is than the disadvantage at the end.Therefore we have designed a kind of specific purpose tool and have been installed on the vertical drill, can realize easily that hole inside groove and the counter of hole inner face scrape, and improve working (machining) efficiency and reduced the equipment input that effect is obvious in actual the use.
Summary of the invention
The purpose of this utility model is to provide a kind of simple processing method, replaces lathe, boring machine, machining center to finish the anti-processing of scraping of hole inside groove and hole inner face with vertical drill, makes it reach cost efficiency, reduces the purpose that drops into.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of instrument of machining hole inside groove, have handle of a knife and the overcoat of fixedlying connected with handle of a knife, in overcoat, be set with and be provided with eccentric cutter spindle, in the eccentric orfice of eccentric cutter spindle, be set with the mandrel that rotates synchronously with eccentric cutter spindle, be installed with cutter head in the end of mandrel; Offer spiral gathering sill on the coat, eccentric cutter spindle is provided with roller, and roller is arranged in the gathering sill; The periphery that stretches out the overcoat part of eccentric cutter spindle is provided with and compresses positioner, the described positioner that compresses comprises bearing block, bearing, positioning sleeve composition, bearing is installed in the bearing block and is sleeved on the eccentric cutter spindle, and bearing block one front end stretches in the positioning sleeve and by adjusting nut fixedlys connected with positioning sleeve; Between eccentric cutter spindle and overcoat, be provided with spring.
For the ease of the installation of cutter head, further: be provided with the cutter head installing hole in the end of mandrel, cutter head is inserted in the cutter head installing hole, and one of cutter head is stretched out the mandrel periphery, is provided with the cutter head housing screw at the end face of mandrel.
In order to realize that eccentric cutter spindle and mandrel rotate synchronously, the installation site of positioning core axle in eccentric cutter spindle simultaneously, further: between eccentric cutter spindle and mandrel, be provided with feather key.
The utility model is simple in structure, and modern design by a kind of specific purpose tool is installed on the vertical drill main shaft, when the vertical drill main shaft rotates with axial feed motion, by eccentric, realizes radially feed, thereby reaches processing request, and is easy to operate.

The specific embodiment
The instrument of a kind of machining hole inside groove as shown in Figure 1, have handle of a knife 1 and the overcoat 2 of fixedlying connected with handle of a knife 1, in overcoat 2, be set with and be provided with eccentric cutter spindle 3, in the eccentric orfice of eccentric cutter spindle 3, be set with mandrel 4, between eccentric cutter spindle 3 and mandrel 4, be provided with feather key 12, be provided with cutter head installing hole 10 in the end of mandrel 4, cutter head 5 is inserted in the cutter head installing hole 10, one of cutter head 5 is stretched out mandrel 4 peripheries, is provided with cutter head housing screw 11 at the end face of mandrel 4 and is used for fixing cutter head 5; Offer spiral gathering sill 6 on overcoat 2, eccentric cutter spindle 3 is provided with roller 7, and roller 7 is arranged in the gathering sill 6; The periphery that stretches out overcoat 2 parts of eccentric cutter spindle 3 is provided with and compresses positioner 8, the described positioner 8 that compresses comprises that bearing block 8-1, bearing 8-2, positioning sleeve 8-3 form, bearing 8-2 is installed in the bearing block 8-1 and is sleeved on the eccentric cutter spindle 3, and bearing block 8-1 one front end stretches in the positioning sleeve 8-2 and by adjusting nut 8-4 fixedlys connected with positioning sleeve 8-2; Between eccentric cutter spindle 3 and overcoat 2, be provided with spring 9.
The concrete course of work is: handle of a knife 1 docks with the vertical drill main shaft, and instrument is when free state, and under the effect of spring 9 restoring forces, roller 7 slides to nadir in gathering sill 6, and cutter head 5 also goes to the left side.When cutter head 5 enters in the hole, when adjusting nut 8-4 contact workpiece A face, main shaft continues downward feeding, eccentric cutter spindle 3 is replied, and drives roller 7 simultaneously and moves in gathering sill 6, and cutter head 5 also slowly rotates to the right, be equivalent to realize radial motion, finish with this and cut groove processing.Adjust nut 8-4 and can regulate the H size, as be adjusted to the Ha size, realize then that the B face is counter to scrape.Cut the degree of depth of groove by the offset of eccentric cutter spindle 3, the lift of gathering sill 6 and the amount of feeding control of main shaft.
