Description

The accurate drilling machine of one kind drilling

Technical field

The present invention relates to drilling machine technical field, specially a kind of accurate drilling machine that drills.

Background technology

Part usually needs to use puncher and it is punched during processing, so that part can be assembled Or work, and manpower cannot complete punching when running into hardness higher part, it is therefore desirable to use drilling machine and drilled.

Drilling machine is referred to using harder than object, sharper keen instrument by rotary cutting or the side of rotary squeezing Formula, the machinery and equipment that cylindrical hole or hole are left on object is referred to as.Also there are referred to as rig, puncher, perforator, through hole Machine etc..

Because drilling machine is when being drilled, the rotation of drill bit meeting high speed, when the drill bit of high speed rotation runs into part, zero Part is subject to the effect of centrifugal force and is moved, in order that drilling is more accurate, a fixation can be all arranged on drilling machine Device is used for retaining element, and so as to prevent part to be moved in drilling, but the drilling machine that currently there are is fixed The clamping effect of device is poor, part plus man-hour small shake still can occur, and drill bit also can be trembled in drilling Dynamic, these small shakes can all affect the accuracy for drilling, so as to error not enough accurately occurs in the processing for causing part, reduce The qualification rate of part.

The content of the invention

It is an object of the invention to provide a kind of accurate drilling machine that drills, possesses the advantage of fixation, the back of the body is solved The clamping effect of the drilling machine fixing device that currently there are mentioned in scape technology is poor, and part is adding man-hour still can send out Small shake is given birth to, and drill bit also can be shaken in drilling, and these small shakes can all affect the accuracy for drilling, So as to error not enough accurately occurs in the processing for causing part, the problem of the qualification rate of part is reduced.

For achieving the above object, the present invention provides following technical scheme：The accurate drilling machine of one kind drilling, including base, The left side of the base top is fixedly connected with the bottom of lifting column, and on the surface of the lifting column lifting platform is slidably connected, The right side of the lifting platform is fixedly connected with the side of fixed plate, side and drilling equipment of the fixed plate away from lifting platform Side is fixedly connected, and the top of the base and fixing device is installed with below drilling equipment.

The drilling equipment includes block, and motor housing, the inside of the motor housing are inlaid with the top of the block Motor is installed with, the output shaft of the motor sequentially passes through the bottom of motor housing and block and consolidates with the top of installing plate Fixed connection, the side of the installing plate is fixedly connected with the inwall of bearing, and the bottom of the block is installed with limiting plate, The bearing is embedded in limiting plate circle centre position, and the bottom of the installing plate is installed with drill bit.

The fixing device includes placing plate, and the top and bottom of the placement plate inner chamber slidably connect ratch, institute State and groove is offered at the top of placement plate, and two rooted tooth bars are installed with connecting rod near the one end for placing cavity wall in plate, One end of the connecting rod is fixedly connected through groove and with the bottom of the clamping plate for placing top of the plate portion, the placement plate inner chamber activity Gear is installed, the gear is engaged with ratch, and one end of gear is fixedly connected with one end of rotating shaft, one end of the rotating shaft Pass the side of placement plate inner chamber and be hinged with one end of gag lever post, and place the front of plate and be fixedly connected with and gag lever post phase The limited block matched somebody with somebody.

Preferably, the side of the limiting plate is fixedly connected with the side of limiting platform, and limiting platform is slidably connected at liter The surface of drop post, and the top of limiting platform is fixedly connected with the bottom of connecting rod, the top of connecting rod and the bottom of lifting platform It is fixedly connected.

Preferably, the output shaft of the drill bit, installing plate, bearing and motor is respectively positioned on same vertical curve.

Preferably, the gear be located at place plate inner chamber axis at, and the length of two rooted tooth bars be placement plate it is long / 2nd of degree.

Preferably, the limited block is in annular, and limited block is located remote from the side of plate and rounded is arranged with stopper slot.

Preferably, the drill bit is located on the axis for placing plate.

Compared with prior art, beneficial effects of the present invention are as follows：

1st, the present invention passes through to arrange fixing device, so as to the part placed on the securing means be fixed so as to which drilling is more Plus it is accurate, by rotating shaft so as to band moving gear is rotated, when pinion rotation, upper and lower two rooted teeth bar is driven to contrary Direction is moved, so that the clamping plate at the top of fixed plate is clamped to part, then by rotary spacing bar, is made spacing Bar is snapped in the stopper slot opened up on limited block, so as to be defined to gag lever post, so that rotating shaft cannot be rotated, so that tooth Wheel is more stable, and because gear is defined, therefore ratch cannot be moved, so the situation that clamping plate just will not shake, Reach fixing device in reduction boring procedure to shake, so that part processes more accurate effect.

2nd, the present invention drives installing plate to be rotated by arranging drilling equipment by electric motor starting, so that drill bit is carried out The work of drilling, and while by the cooperation of bearing, limiting plate limiting platform and connecting rod, installing plate is carried out it is spacing, from And reduce the installing plate during drilling and shake, so as to cause the vibrations of drill bit, so as to reach drilling accuracy is increased Effect.
