Description
Technical field
This utility model relates to a kind of drill bit detection components.
Background technology
Drill bit is to go out through hole or blind hole in order to drilling on solid material, and existing hole can carry out the cutter of reaming.Drill bit includes knife bar and is positioned at two main cutting edges of knife rod head, accompanies chisel edge between two main cutting edges.
Drill bit by numerical control drilling machine to solid material drilling blind hole during, two main cutting edges of its head and chisel edge abrasion are the fastest, in order to make the blind hole depth on each solid material keep consistent, after a number of solid material of drilling, need the length of drill bit is detected, adjust the displacement of drill bit in time.
When the abrasion of drill bit is less, workman is difficult to directly measure the length of drill bit with ruler so that the degree of depth of blind hole has certain deviation.
Utility model content
The deficiency existed for prior art, this utility model is to provide a kind of drill bit detection components, by arranging tooth bar, the first gear and the second gear on detection seat, reach to be easy to workman and observe the length of drill bit, make workman in time the position of drill bit be adjusted, reach to make the degree of depth of blind hole to keep consistent purpose.
For achieving the above object, this utility model provides following technical scheme: a kind of drill bit detection components, it is characterized in that: include detecting seat, the tooth bar for arranging is slidably connected with drill bit conflict on described detection seat, intermeshing first gear and the second gear it is rotatably connected on described detection seat, described tooth bar and the first gear engagement, described second gear radially on be fixed with pointer, described detection seat is fixed with the graduated disc corresponding with pointer.
By using technique scheme, drill bit is clamped on numerical control drilling machine, drill bit is placed in above tooth bar, by drill bit is moved toward the direction near tooth bar, make drill bit identical by numerical control drilling machine displacement with after use before use, and drill bit use after length shorter, drill bit is after conflicting with tooth bar, the displacement of tooth bar is different, rack drives the first gear and the second gear are rotated, by gear ratio between the first gear and the second gear, first gear and the second gear linear velocity are equal, but angular velocity is different, the angle making the second gear that pointer can be driven to rotate is bigger, there is bigger change the position pointing to graduated disc twice before and after can realizing pointer, so that workman can between observe the abrasion condition of drill bit, adjust drill bit position in numerical control drilling machine in time
This utility model is further arranged to: be provided with elastic component on described detection seat, and the two ends of described elastic component are fixed with detection seat, tooth bar respectively and are connected.
By using technique scheme, the setting of elastic component, can make drill bit that tooth bar is applied active force so that tooth bar produces certain displacement, make tooth bar that elastic component is produced certain deformation, elastic force is produced by deformation, after drill bit is not conflicted with tooth bar, tooth bar is resetted by the effect of elastic force, easy and simple to handle, without the operation that workman is extra, promote workman's production efficiency.
This utility model is further arranged to: slidably connecting the protective cap for conflicting with drill bit on described detection seat, described protective cap is connected with tooth bar.
By using technique scheme; owing to the end of drill bit is the sharpest; the setting of protective cap; can avoid drill bit that tooth bar causes directly damage; and iron filings can be avoided to enter between tooth bar and first, second gear cause tooth to be damaged and cannot use; add tooth bar, the first gear, the service life of the second gear, when protective cap is damaged, it is only necessary to the protective cap more renewed.
This utility model is further arranged to: be provided with on described detection seat for protective cap conflict guiding groove, the long side direction of described guiding groove be arranged in parallel with the long side direction of tooth bar.
By using technique scheme, by the elastic force effect of elastic component, tooth bar is made to be subjected to displacement by the effect of elastic force; rack drives protective cap is made to be subjected to displacement; the inwall making protective cap and guiding groove is conflicted, and protective cap plays spacing effect, it is to avoid protective cap is deviate from from tooth bar.
This utility model is further arranged to: offer mounting groove and lead-over groove on described detection seat, and described mounting groove is connected with guiding groove by described lead-over groove.
By using technique scheme, by protective cap is entered in lead-over groove along mounting groove, then enter into from lead-over groove in guiding groove, mounting cap can be made to be connected with detection seat, easy and simple to handle, promote the production efficiency of workman further.
This utility model is further arranged to: described graduated disc includes the angle index being located at fixed plate in Semicircular fixed plate and quarter, and described angle index is that sector is arranged.
By using technique scheme, the fan-shaped fixed plate arranged and angle index, the sensing that can make pointer is the most accurate, it is simple to workman directly observes.
In sum, this utility model has the advantages that
Drill bit before being used by numerical control drilling machine and the drill bit after use are placed in the top of protective cap; drill bit is all moved identical distance toward the direction near protective cap; owing to the drill bit after using produces abrasion; the shift length of the drill bit band carry-over bar after using is shorter; the selected angle making pointer is less; position by twice contrast pointer of front and back; workman can be allowed to understand the abrasion length knowing drill bit; the most only need to regulate drill bit position on numerical control drilling machine, the degree of depth of blind hole can be made to keep consistent.
