Abstract
The utility model provides a countersink cutter, including cutter body and the stop gear of setting on the cutter arbor, stop gear includes: upper bracket, thrust ball bearing, undersetting and gland, the upper bracket with the cutter arbor is connected, undersetting upper end with gland connection, and the undersetting lower extreme is established to spacing platform, thrust ball bearing seat circle install in on the undersetting, the thrust ball bearing blowout patche install in on the upper bracket, the upper bracket below is provided with the uide bushing. The utility model discloses a countersink cutter can fix a position the degree of depth of counterbore, avoids the damage of location to the work piece moreover.
Description
Technical field
This utility model relates to counter bore processing cutter field, particularly relates to a kind of countersink.
Background technology
Countersink is that the hole of processing on workpiece is scraped planar end surface or cuts out the machining tool of taper, cylindrical bore.When adopting radial drill to part spot-facing, in order to control the degree of depth of spot-facing, before spot-facing, the feeding depth of countersink being carried out labelling location, regulate the degree of depth of spot-facing by observing reference mark, depth tolerances is big, affects working (machining) efficiency or product quality.
Utility model content
The utility model proposes a kind of countersink, solve the degree of depth of spot-facing problem rambunctious in prior art.
The technical solution of the utility model is achieved in that
A kind of countersink, including cutter hub and the position-limit mechanism being arranged on knife bar, described position-limit mechanism includes: upper bracket, thrust ball bearing, undersetting and gland, and described upper bracket is connected with described knife bar；Described undersetting upper end is connected with described gland, and undersetting lower end is set to limiting stand；Described thrust ball race is installed on described undersetting；Described thrust ball bearing shaft washer is installed on described upper bracket；Described upper bracket is arranged below fairlead.
Preferably, in described countersink, between described upper bracket and described gland, it is provided with steel ball.
Preferably, in described countersink, it is connected with the first locking nut at described gland.
Preferably, in described countersink, it is arranged over the second locking nut at described upper bracket.
The beneficial effects of the utility model are: countersink of the present utility model, it is possible to the degree of depth of location spot-facing, and avoid the location damage to workpiece.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of countersink of this utility model.
In figure:
1, knife bar；2, upper bracket；3, thrust ball bearing；4, undersetting；5, gland；6, fairlead；7, steel ball.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
A kind of countersink as shown in Figure 1, including knife bar 1 and the position-limit mechanism being arranged on knife bar, position-limit mechanism includes: upper bracket 2, thrust ball bearing 3, undersetting 4, gland 5, fairlead 6 and steel ball 7.Upper bracket 2 is connected with described knife bar 1, and upper bracket 2 is arranged over the second locking nut；Undersetting 4 upper end is connected with gland 5, and undersetting 4 lower end is set to limiting stand；Gland 5 is connected with the first locking nut；Thrust ball bearing 3 seat ring is installed on described undersetting 4；Thrust ball bearing 3 blowout patche is installed on upper bracket；Fairlead 6 is positioned at below upper bracket 2；Steel ball 7 is between upper bracket 2 and gland 5.
The work process of countersink is: the limiting stand of undersetting is for limiting the spot-facing degree of depth of workpiece, and when limiting stand encounters workpiece, under the thrust ball bearing effect with steel ball, undersetting is not rotated further by, and upper bracket is rotated further along with knife bar.Owing to limiting stand and knife bar can relatively rotate, therefore the spacing rear surface of the work contacted with limiting stand will not damage.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
Claims (4)
1. a countersink, including cutter hub and the position-limit mechanism being arranged on knife bar, it is characterised in that described position-limit mechanism includes: upper bracket, thrust ball bearing, undersetting and gland, and described upper bracket is connected with described knife bar；Described undersetting upper end is connected with described gland, and undersetting lower end is set to limiting stand；Described thrust ball race is installed on described undersetting；Described thrust ball bearing shaft washer is installed on described upper bracket；Described upper bracket is arranged below fairlead.
2. countersink according to claim 1, it is characterised in that be provided with steel ball between described upper bracket and described gland.
3. countersink according to claim 1, it is characterised in that be connected with the first locking nut at described gland.
