Description

Can locate the cutter head of boring a hole that changes blade

Technical field:

The utility model relates to a kind of cutter of toolroom machine, refers to a kind of cutter head of boring a hole that locating of tool rest locating structure changes blade of improveing especially.

Background technology:

Bore a hole cutter head such as Fig. 4 and shown in Figure 5 of existing plugged blade, for being provided with the knife bar 50 of boring a hole, around knife bar 50 tops of boring a hole, form a connecting support 51, the left and right sides of connecting support 51 outsides is provided with two abaculus 52, be provided with a tool rest 53, the corresponding connecting support 51 in the bottom of tool rest 53 forms a spiro-locking section 54, forms an embedding ditch 55 with spiro-locking section 54 inner faces, with embedding ditch 55 engaging and screw lock in connecting support 51, in the top of tool rest 53 with dismountable form screw lock one blade 56.

Aforementioned Hole boring knife cooperates the tool rest 53 of detachable combination to reach replaceable effect with blade 56, and the user is provided reused Hole boring knife utilization whereby.

When yet aforementioned Hole boring knife screw lock is installed tool rest 53, owing to only locate the position of tool rest 53 with embedding ditch 55 involutory two abaculus 52, therefore make the space between embedding ditch 55 and the abaculus 52 cause the problem that tool rest 53 is partial in the screw lock process, in the process of screw lock tool rest 53, need to ajust the angle of blade 56, cause the more time-consuming shortcoming of installation.

Summary of the invention:

Because the tool rest of the existing cutter head of boring a hole is easy to generate deflection in cohesive process, therefore need adjust and produce the more time taking shortcoming of installation, the utility model forms the structure of location between tool rest and connecting support, guide the position of tool rest whereby and make the process of installation can be more convenient.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

Can locate the cutter head of boring a hole that changes blade, comprise:

One knife bar of boring a hole, this knife bar of boring a hole forms a connecting support around the top, wear a screw in the center of this connecting support, is arranged with a storage tank in this connecting support surface around should screw, protrudes out the edge clipping of a ring-type inwardly in the outer end of this storage tank perisporium;

One tool rest, the bottom of this tool rest is to forming a spiro-locking section by connecting support, be sticked in this connecting support with spiro-locking section, in this spiro-locking section to wearing a counter sink by screw, in the inner face of this spiro-locking section to being arranged with a pearl groove by storage tank, be provided with a bolt, this bolt is for being arranged in this counter sink and screw lock in this screw;

Certain hyte part, this positioning component comprises a seed pearl and a spring, and this spring and this seed pearl are the inside and outside both sides of being located in this storage tank, the inner of this seed pearl for be resisted against this spring and with around rely on this edge clipping, the outer end of this seed pearl is resisted against this pearl groove, and

One blade, this blade with dismountable form screw lock in the top of this tool rest.

Further, the utility model forms an inserted link in the bottom of the knife bar of boring a hole, form a head in this inserted link top, all sides in this head form a recess, described connecting support is disc and is formed at this recess, form the vertical plane of a circle in this connecting support surface outwardly, described screw is the center that is arranged in this vertical plane, the left and right sides that should screw is protruded two abaculus outwardly in vertical plane, described storage tank this vertical plane of serving as reasons is arranged with, corresponding two abaculus of the inner face of described spiro-locking section are arranged with the embedding ditch one, are embedded with this embedding ditch and are sticked in two abaculus.

Preferable, the position of storage tank is positioned at the top of described screw, and described pearl groove is semicircular groove.

When the utility model is installed tool rest in the knife bar connecting support of boring a hole, earlier with the blade screw lock in the tool rest top, the embedding ditch of spiro-locking section is aligned connecting support two abaculus again and embed, by the fixing position of tool rest of abaculus, then passing counter sink with bolt locks in connecting support admittedly with tool rest.

Because in the tool rest screw lock process, the seed pearl of positioning component can continue to lean the pearl groove of spiro-locking section, therefore can locate the position about tool rest whereby, makes tool rest can not produce the skew that turns to because of the screw lock of bolt, the required time of blade is ajusted in saving, makes things convenient for the user that utilization is installed.

The specific embodiment:

Below in conjunction with drawings and Examples the utility model is described in detail:

The utility model is a kind of cutter head of boring a hole that changes blade of locating, and please referring to the preferred embodiment of Fig. 1-Fig. 3, comprising:

One knife bar 10 of boring a hole, one inserted link 11 is formed on knife bar 10 bottoms of boring a hole, form a head 12 in inserted link 11 tops, form a recess 13 in head 12 all sides, form a discoidal connecting support 14 in recess 13, form a circular vertical plane 15 in connecting support 14 surface outwardly, wear a screw 16 in the center of vertical plane 15, the left and right sides of corresponding screw 16 is protruded two abaculus 17 outwardly in vertical plane 15, the top of corresponding screw 16 is arranged with a storage tank 18 in vertical plane 15, protrudes out the edge clipping 181 of a ring-type inwardly in the outer end of storage tank 18 perisporiums.

One tool rest 20, the corresponding connecting support 14 in the bottom of tool rest 20 forms a spiro-locking section 21, corresponding screw 16 wears a counter sink 22 in the middle of spiro-locking section 21, corresponding two abaculus 17 of inner face in spiro-locking section 21 are arranged with embedding ditch 23 one, spiro-locking section 21 is embedded at two abaculus 17 with embedding ditch 23, be posted by vertical plane 15 with inner face whereby, be arranged with the pearl groove 24 of a semicircle in the corresponding storage tank 18 of inner face of spiro-locking section 21, be provided with a bolt 25, bolt 25 is locked in connecting support 14 with tool rest 20 whereby for being arranged in counter sink 22 and screw lock in screw 16.

Certain hyte part 30, positioning component 30 comprises a seed pearl 31 and a spring 32, spring 32 and seed pearl 31 are located at the inside and outside both sides in the storage tank 18, rely on edge clipping 181 around the seed pearl 31, and the outer end of stretching out storage tank 18 is resisted against pearl groove 24 location.

One blade 40, blade 40 with dismountable form screw lock in the top of tool rest 20.

Storage tank 18 of the present utility model is except as described in preceding preferred embodiment, be located at outside screw 16 tops, can also be located at the below of screw 16 and cooperate installing positioning component 30, seed pearl 31 with positioning component 30 leans the effect that the pearl groove 24 of being located at spiro-locking section 21 inner face downsides reaches the location, and the design the utility model that so changes the position is not limited at this.

When the utility model is installed tool rest 20, please referring to Fig. 2, Fig. 3, earlier with blade 40 screw locks in tool rest 20 tops, embedding ditch 23 with spiro-locking section 21 aligns 17 embeddings of 14 liang of abaculus of connecting support again, by the fixing position of tool rest 20 of abaculus 17, then pass counter sink 22 screw locks in screw 16 with bolt 25, tool rest 20 is locked in connecting support 14 admittedly, because in the screw lock process, the seed pearl 31 of positioning component 30 can lean pearl groove 24, locatees the position of tool rest 20 simultaneously, therefore makes tool rest 20 can not produce the skew that turns to because of the screw lock of bolt 25, the 40 needed times of blade are ajusted in saving, make things convenient for the user that utilization is installed.
