Description
Technical field:
The utility model relates to the machine tool technology field, is specifically related to a kind of drilling machine degree of depth limit device.
Background technology:
In mechanical processing industry, the processing of sensitive drilling machine is very general, and the degree of depth of processing generally is difficult to control to unanimity, can't guarantee especially when particularly reaming, and is dark or shallow, sometimes even can collapse the cutter phenomenon.Partially manual feeding drilling machine band degree of depth limit device is also arranged, the big bearing of general employing is fixed on the sleeve, on the big bearing screw mandrel is housed, is with nut on the screw mandrel, nut is fixed on and moves up and down in the chute in the main shaft casing and be provided with collision block at the range place, rotary screw when deciding journey, adjust the position of nut in chute in advance, when hand feed arrived required Working position, nut was run into collision block, feeding stops, and has finished the Cheng Jiagong that decides to the degree of depth.These drilling machine degree of depth limit devices generally need a plurality of parts combinations, and profile is huger, complex structure, cost are higher, the degree of depth is decided journey and regulated the speed slowly (screw mandrel revolves and turns around, and the degree of depth can only be adjusted a pitch), installs also more bothersome.
The utility model content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency provides a kind of rational in infrastructure, with low cost, degree of depth to decide journey adjustment a kind of drilling machine degree of depth limit device fast, easy to operate, easy for installation.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of drilling machine degree of depth limit device, it is characterized in that: comprise the main shaft casing, be provided with the tooth axle in the described main shaft casing, described main shaft casing is provided with blind flange, described blind flange is installed on the main shaft casing by screw, a sleeve is installed in the described main shaft casing, main shaft is installed on and does gyration in the sleeve, described main shaft casing one side is provided with handle set, and described handle set is provided with the one handle bar, and described handle set is provided with graduated ring, be equipped with on the described graduated ring and decide the journey collision block, described graduated ring is provided with lock-screw, and described graduated ring dallies at handle set, when lock-screw is locked, graduated ring and handle set turn round together, described handle set is provided with a flat key, and described blind flange is provided with positive stop, and described graduated ring one side is provided with the zero-bit direction board;
Described handle set is connected on the main shaft casing by connecting bolt;
Described tooth axle is installed in the main shaft casing, and an end supports by the hole in the main shaft casing, and the other end supports by blind flange;
Described tooth axle is meshed with tooth bar on the sleeve;
Described handle set is installed on the tooth axle by flat key;
Described zero-bit direction board is connected on the blind flange.
The beneficial effects of the utility model are: when needing the degree of depth to decide journey, according to the working depth needs, unclamp the lock-screw on the graduated ring, rotate graduated ring, with the alignment of the depth location line on graduated ring zero-bit direction board, lock-screw on the locking graduated ring, pull handlebar, handlebar drives the handle set rotation, and the handle set rotation drives the rotation of tooth axle, tooth bar on the tooth axle rotating band moving sleeve moves downward, sleeve moves downward and drives main shaft and do feed motion downwards, and when arriving required working depth, the journey collision block of deciding on the handle set bumps against with the positive stop that is installed on the blind flange, hand feed stops, and has finished the Cheng Jiagong that decides to the degree of depth.This drilling machine degree of depth limit device only needs to increase at common manual feeding drilling machine decide journey collision block, positive stop, zero-bit direction board, graduated ring and five simple findings of lock-screw and just can realize, have simple in structure, installation is simple, with low cost, the degree of depth is decided advantages such as the journey adjustment is fast, easy to operate.
