Description
Technical field
The present invention relates to a kind of machining tool, particularly the handle operation mechanism of this lathe.
Background technology
In the prior art, there is a kind of brill to attack folding seat bed, it can be holed and tapping, when boring and tapping, realize feeding and return this handle operation mechanism by handle operation mechanism, mainly comprise the tooth axle that is installed on the lathe bed, tooth axle one end is connected with resetting-mechanism, and the tooth axle other end is provided with handle set, and handle set is provided with handle; Described handle set is sleeved on an end of limit friction cover and fixes with the limit friction cover, described limit friction cover is outside key is installed in the tooth axle, the other end of limit friction cover is provided with the limit friction dish, the limit friction dish is sleeved on the axle journal of tooth axle rotationally, be provided with corresponding rubbing surface between limit friction cover and the limit friction dish, the corresponding end of described tooth axle and handle set is provided with the retaining mechanism with the rubbing surface locking between limit friction cover and the limit friction dish.During its work, can select boring processing and tapping processing, be processed as example with boring, during boring, main motor-driven drill bit continues to rotate, and need hole adds man-hour, passes through turning handle, handle drives the tooth axle and rotates, and the tooth axle drives the drill bit rectilinear motion, and the drill bit of rotation is holed at surface of the work.After the release handle, under the effect of resetting-mechanism, drill bit can be return initial position voluntarily.Be the restriction bit run, but limit friction cover and limit friction dish lock mutually, at this moment, limit friction cover and limit friction dish link, when the limit friction dish turned to spacing position, no longer rotation can limit drill stroke.Separable and combination between limit friction dish and the limit friction cover can be adjusted bit run like this.Its weak point is: it is in the drill bit feeding and the process of returning, drill bit remains rotary state, can bring some potential safety hazards, especially under the fixing firm inadequately situation of workpiece, in the drill bit fall back process, cause the workpiece transfer sometimes, break workpiece easily, also easily the operator is damaged.
For addressing the above problem, some drilling machine adopts and sets up floor push in the prior art, and this floor push links to each other with control circuit, can realize emergent the shutdown.Nonetheless, this device still needs artificial manipulation, and drill bit is stopped operating.
Summary of the invention
The purpose of this invention is to provide a kind of lathe handle operation mechanism, make it can be after release handle, drill bit can stop operating immediately, to avoid security incident.
The object of the present invention is achieved like this: a kind of lathe handle operation mechanism, comprise the tooth axle that is installed on the lathe bed, and tooth axle one end is connected with resetting-mechanism, and the tooth axle other end is provided with handle set, and handle set is provided with handle; Described handle set is sleeved on an end of limit friction cover and is connected with the limit friction cover, described limit friction cover is outside key is installed in the tooth axle, the other end of limit friction cover is provided with the limit friction dish, the limit friction dish is sleeved on the axle journal of tooth axle rotationally, be provided with corresponding rubbing surface between limit friction cover and the limit friction dish, the corresponding end of described tooth axle and handle set is provided with the retaining mechanism with the rubbing surface locking between limit friction cover and the limit friction dish; Described handle set one side excircle is provided with a circumferential recess, be set with sliding sleeve with the corresponding position of circumferential recess on the handle set, sliding sleeve is fixed with the switch plectrum outward, described switch plectrum stretches in the switch enclosure fixing on the lathe bed, be provided with two travel switches of controlling main motor action respectively in the switch enclosure, the switch plectrum inserts between two travel switches; Be embedded with damping wire in the described circumferential recess.
During this device work, have two kinds of working methods equally, one is the tapping working method, its two for boring working method, under two kinds of working methods, no matter when, release handle, under the drive of resetting-mechanism, the switch driving lever can unclamp corresponding travel switch, realize the timely stall of main motor, avoid security incident, when needing feeding, pulled handle, drive the switch plectrum and trigger travel switch, main motor rotates once more, can realize the drill bit feeding, because handle set is resetting and during feeding, its stroke is much larger than two distances that form between the switch, the design of sliding sleeve and damping wire makes the certain frictional force of generation between sliding sleeve and the handle set, when handle set rotates, sliding sleeve is followed handle set and is rotated together, but, after the switch driving lever is stirred corresponding travel switch action, because the obstruction of travel switch is arranged, produce relative slip between handle set and the sliding sleeve, the course feed that has guaranteed drill bit with return.The technical scheme that this device adopts damping spring and travel switch to combine has solved the hidden danger that drilling machine exists for a long time dexterously, and compared with prior art, beneficial effect of the present invention is: it can realize the shutdown of loosing one's grip, and is safe.It not only can be used on the drilling machine, also can be used to bore tapping dual-purpose tool.
For guaranteeing reliable lock, simple in structure, described retaining mechanism comprises screw rod, the screw rod threaded one end is screwed in the axle head of tooth axle, the end of limit friction cover is fixed with connecting plate, the described screw rod other end passes connecting plate and fixes with the locking handwheel, and described locking handwheel inner face abuts in the connecting plate outside.By the locking handwheel, can lock at any time and unclamp retaining mechanism, it is easy and simple to handle.
For guaranteeing that further adopting little axial force can make between limit friction cover and the limit friction sheet is fixed well, the rubbing surface between described limit friction cover and the limit friction dish is the conical surface.
Spacing reliable for guaranteeing, described limit friction dish is provided with cannelure towards lathe bed one side end face, is provided with spacing bearing pin in the cannelure, and lathe bed is provided with a limited block and stretches in the cannelure.When the limit friction dish rotated, when spacing bearing pin contacted with limited block, the limit friction dish no longer rotated; It is simple in structure, uses reliable.It is spacing can also to adopt the other technologies scheme, and for example: be provided with cannelure at the limit friction dish on lathe bed one side end face, less than 360 ° of angles, the limited block that is provided with on the lathe bed stretches in the cannelure on the circumferencial direction of this cannelure; This technical scheme has been saved spacing bearing pin, uses also very reliable.
When this device is used on the tapper, because of workpiece in the tapping process fixes, cutter has also entered workpiece, and promptly its relative position is fixing, for realizing that cutter is under not lifting situation, pass through handle, also can trigger travel switch, realize stall or counter-rotating, can overlap the upper edge at limit friction and circumferentially establish fan groove, insert in the described fan groove dog screw end that radially is connected on the handle set, and handle set and limit friction cover can relatively rotate within the specific limits.
