Abstract
The utility model discloses a drill bit for processing sheet materials. The drill bit comprises a chassis and a top disk, wherein a shaft sleeve is arranged at an end face of the chassis, a groove is arranged on the other end face of the chassis, a stepped hole communicating with the shaft sleeve is arranged on the central portion of the groove, the top disk is arranged in the chassis, and one end face of the chassis is provided with a guide shaft, where a spring is sleeved and of which the end penetrates through the shaft sleeve. The spring is positioned in the stepped hole, and an outward extending rib is arranged on the upper end face of the outer circumference of the chassis, and a circular drill sheet is fixedly installed on the rib through a clamp. A zigzag blade is arranged on the lower end of the circular drill sheet. The drill bit is reasonable in structure design, convenient for installation and use, stable in working process, and suitable for mass production. Moreover, the drill bit is labor saving and time saving, minimizes labor intensity and improves working efficiency.
Description
Technical field:
The utility model relates generally to a kind of drill bit, relates in particular to a kind of drill bit of machining sheet.
Background technology:
Plank is exactly the wood plank that adopts complete timber to process.These sheet materials are sturdy and durable, lines nature, are the choosings in excellent in the finishing.Big I according to sheet material is applied to different aspects such as household, technology, toy respectively, in difform sheet material process, need carry out different operation.Circular sheet material is being added man-hour; Existing processing unit (plant) complex structure, troublesome poeration, and inefficiency can not satisfy the requirement that batch machining is produced; Existing drill bit is boring or a blind hole on entity; Therefore being applied in circular sheet material in the material process, also is a kind of imagination, does not also occur corresponding device thereof at present.
The utility model content:
The purpose of the utility model is in order to remedy the deficiency of prior art; A kind of drill bit of machining sheet is provided; Solved existing circular sheet material processing unit (plant) complex structure, troublesome poeration, and inefficiency, can not satisfy the problems such as requirement that batch machining is produced.
The utility model is realized through following technical scheme:
A kind of drill bit of machining sheet includes the chassis, takes over a business, and said chassis one end face is provided with axle sleeve; The other end on said chassis is provided with groove, and said groove middle part is provided with the stepped hole that is interconnected with axle sleeve, the said groove of taking over a business to place the chassis; A said end face of taking over a business is provided with guide shaft, be set with spring on the said guide shaft, and axle sleeve is passed in its end; Said spring is arranged in stepped hole; The upper surface of the excircle on chassis is provided with outward extending rib, and through snap fit the circular sheet that bores is installed, and said circular lower end of boring sheet is provided with serrated edge.
The drill bit of described machining sheet is characterized in that: the circular serrated edge end of boring sheet of end face protrusion on described chassis.
Its principle is: the boring principle according to drill bit, its structure is changed, and reached requirement towards circular sheet material, bore sheet through the circle that has serrated edge in the process and in the process of rotation, sheet material is constantly located cutting; The chassis and take over a business between spring constantly compress, after cutting is accomplished, through the reaction of spring; Sheet material is ejected, the circular sheet that bores is separated with sheet material, simple to operate; Time saving and energy saving, high efficiency is fit to the requirement that batch machining is produced.And the design of the step through excircle upper surface, chassis, its positioning action, avoided circular brill sheet when work owing to reaction force moves up.
The utility model has the advantages that:
The utility model reasonable in design, easy to install, hand labor intensity is little in the process, and is time saving and energy saving, improved operating efficiency, and good stability in the course of work is specially adapted to batch machining production simultaneously.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Referring to accompanying drawing, a kind of drill bit of machining sheet includes chassis 1, takes over a business 2; Chassis 1 one end faces are provided with axle sleeve 3, and the other end on chassis 1 is provided with groove 4, and groove 4 middle parts are provided with the stepped hole that is interconnected with axle sleeve 3; Take over a business 2 place the chassis groove 4, take over a business an end face of 2 and be provided with guide shaft 5, be set with spring 6 on the guide shaft 5; And axle sleeve 3 is passed in its end; Spring 6 is arranged in stepped hole, and the upper surface of the excircle on chassis 1 is provided with outward extending rib 7, and through snap fit the circular sheet 8 that bores is installed; The circular serrated edge end of boring sheet 8 of end face protrusion on chassis 1.
Claims (2)
1. the drill bit of a machining sheet includes the chassis, takes over a business, and it is characterized in that: said chassis one end face is provided with axle sleeve; The other end on said chassis is provided with groove, and said groove middle part is provided with the stepped hole that is interconnected with axle sleeve, the said groove of taking over a business to place the chassis; A said end face of taking over a business is provided with guide shaft, be set with spring on the said guide shaft, and axle sleeve is passed in its end; Said spring is arranged in stepped hole; The upper surface of the excircle on said chassis is provided with outward extending rib, and through snap fit the circular sheet that bores is installed, and said circular lower end of boring sheet is provided with serrated edge.
