Abstract
The invention discloses a tool for drilling central holes of rubber bars. The tool for drilling the central holes of the rubber bars comprises a drill rod, a sleeve, a spring, a sliding sleeve and a positioning block which are sequentially arranged from left to right along the axial direction; the left end of the drill rod is fixed on a lathe clamping head; the right end of the drill rod passes through the sleeve and is connected with an inner hole of the sliding sleeve in a sleeving mode; the right end of the inner hole of the sliding sleeve is of a flaring shape; the outer circle of the sliding sleeve is sleeved in the inner hole of the sleeve; the spring is connected between the middle part of the sliding sleeve and the sleeve; an anti-rotation clamping slot is formed in the outer circle of the right end of the sliding sleeve; a limit screw inserted into the anti-rotation clamping slot is correspondingly arranged at the right end of the sleeve; the sleeve is fixed on the lathe by virtue of a fixing rack; the positioning block is connected with a tail base of the lathe; a conical groove is formed in the left end surface of the positioning block. The tool for drilling the central holes of the rubber bars is simple in structure, easy to operate and high in safety; the workpieces can be replaced without halt; the burrs can be removed without halt; the efficiency is greatly improved.
Description
Technical field
The present invention relates to the field of rubber and plastic workpiece drill centers.
Background technology
Rubber is the latex taking from the plant such as rubber tree, Russian dandelion, the material with elasticity, insulating properties, waterproof and air made after processing.Elastomeric macromolecular compound, is divided into natural rubber and synthetic rubber two kinds.Natural rubber from the plant such as rubber tree, Russian dandelion, extracts colloid aft-loaded airfoil make; Synthetic rubber is then obtained through polymerisation by various monomer.Rubber is widely used in industry or life each side.
Rubber bar uses also widely, but often needs, in end face machining center hole, to feel relieved or to locate, to be convenient to following process or use during the shaping rear use of rubber bar.
In prior art, during people's processing rubber bar end face centre bore, normally rubber bar is directly clamped by lathe dog, and then adjust lathe tool position and process, need lathe to stop after machining at every turn, then wait lathe dog to stop operating, then unclamp lathe dog, take off workpiece, change new unprocessed workpiece, whole process operation is loaded down with trivial details, and waste a large amount of time, efficiency is low.
Summary of the invention
The invention is intended to provide a kind of rubber bar drill centers frock, to improve working (machining) efficiency.
Rubber bar drill centers frock in this programme, comprises the drilling rod, sleeve, spring, sliding sleeve and the locating piece that set gradually from left to right vertically; Drilling rod left end is fixed on lathe dog, drilling rod right-hand member passes sleeve and is socketed sliding sleeve endoporus, sliding sleeve endoporus right-hand member is enlarging shape, sliding sleeve cylindrical is enclosed within hub internal bore, is connected with spring in the middle part of sliding sleeve and between sleeve, and sliding sleeve right-hand member cylindrical is provided with anti-rotation draw-in groove, sleeve right-hand member correspondence is provided with the stop screw inserted in anti-rotation draw-in groove, sleeve is fixed on lathe by fixed mount, and locating piece is connected on tail stock, and locating piece left side is provided with conical socket.
Drilling rod right-hand member is connected and fixed drill bit, during work, workpiece is placed between sliding sleeve and locating piece, then the handle on tail stock is rotated, tail stock is made to drive locating piece to advance, and then advanced against sliding sleeve against the force of the spring by workpiece, hole until workpiece left side is against on drill bit, locating piece moves on, rubber bar end-face central hole and plastic, after machining, move after can making locating piece by the handle on tail stock, workpiece ejects by sliding sleeve under the action of the spring, i.e. replaceable workpiece, achieve the replacing workpiece that do not stop, not stop machining center hole, this programme structure is simple, and processing ease, security is high, and the replacing workpiece that can not stop, and deburring of not stopping, substantially increases efficiency.
Further, also comprise trailing arm, fixed mount is bolted on lathe, facilitates installing/dismounting, fixed mount is connected by screw trailing arm one end, and the trailing arm other end and excircle of sleeve are welded and fixed, and fixedly secure.
Further, locating piece right-hand member is wholely set the connecting rod of taper, and connecting rod inserts tail stock and fixes, and convenient installation is fixed.
Further, trailing arm and sleeve weld place are also provided with reinforcement, strengthen the stability of trailing arm and sleeve connection.
Accompanying drawing explanation
