Description

Drilling machine
Technical field
The utility model relates to a kind of metal-working plants, and in particular to a kind of drilling machine.
Background technique
Drilling machine is widely used in the field of metal processing, when boring 5mm with the hole location of lower relative aperture, due to drill bit outer diameter Through than relatively fine, drill bit is commonly mounted on drilling machine, in bit and metal face contact, once pressure is excessive under drill bit It will lead to drill bit to burst apart, damage, so that the difficulty of processing is higher, cause processing cost higher.
Summary of the invention
It is reliably bored to solve the above problems, avoiding drill bit from damaging the purpose of this utility model is to provide one kind with structure Hole machine.
To achieve the above object, the utility model provides following technical solution: a kind of drilling machine, including rack, described Rack be equipped with lifting platform, the lifting platform is equipped with motor and lifting cylinder, the telescopic rod of the lifting cylinder and position It is connected in the top plate of the frame top, the shaft on the motor and a rotation axis connection, the end of the rotary shaft is spirally connected There is screwed pipe, the other end of the screwed pipe is bolted with the first drilling attachment, is arranged on the outer wall of first drilling attachment The outer wall of positioning ring, positioning ring is socketed with casing, and the second drilling attachment is equipped on the inner wall of close end in described sleeve pipe, It is equipped with spring between first drilling attachment and second drilling attachment, drill bit is installed on the second drilling attachment.
The lifting platform side is equipped with lifting catheter, and the rack is equipped with guide post, which is inserted into the lifting In the inner hole of conduit, lifting platform vertically-guided activity up and down is realized.
Two guide sleeves are equipped on the lifting platform, the rotary shaft is passed through from the inner hole of two guide sleeves.
Drill bit is mounted on the second drill jig when processing hole location of the 5mm with lower relative aperture by this structure of the utility model On tool, the first drilling attachment is conducted rotary force to the second drilling attachment by casing, drives the rotation of the second drilling attachment, Drill bit makes the pushing power of drill bit keep certain dynamics when processing metal, through the elastic force of spring, avoids to push in this way Lead to bit damage greatly, when the metal of the bore of simultaneous processing 5mm or more, drill bit can be clamped on the first drilling attachment, be made The transmitting of pressure must be descended more direct, processing efficiency is improved, just realize avoid drill bit from damaging with the reliable technology of structure in this way Effect has combined usually normal use.
The utility model is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Specific embodiment
The utility model is specifically described below by embodiment.
As shown in Figure 1, present embodiment discloses a kind of drilling machine, including rack 1, rack 1 are equipped with lifting platform 2, lifting Platform 2 is equipped with motor 3 and lifting cylinder 4, and the telescopic rod of lifting cylinder 4 is connect with the top plate for being located at 1 top of rack, on motor 3 Shaft 31 connect with a rotary shaft 5, the end of the rotary shaft 5 is bolted with screwed pipe 6, and the other end of screwed pipe 6 is bolted with One drilling attachment 7 is arranged with positioning ring 8 on the outer wall of first drilling attachment 7, and the outer wall of positioning ring 8 is socketed with casing 81, is covering Pipe 81 is equipped with the second drilling attachment 9 on the inner wall of close end, sets between the first drilling attachment 7 and the second drilling attachment 9 There is spring 10, drill bit is installed on the second drilling attachment 9.
2 side of lifting platform is equipped with lifting catheter 21, and rack 1 is equipped with guide post 11, which is inserted into lifting catheter 21 In inner hole, the activity of about 2 vertically-guided of lifting platform is realized, guarantee the up and down stability of lifting platform 2.
Two guide sleeves 22 are equipped on lifting platform 2, rotary shaft 5 is passed through from the inner hole of two guide sleeves 22.Successively keep rotation The stability that shaft 5 rotates, improves the precision of drilling.
Drill bit is mounted on the second drill jig when processing hole location of the 5mm with lower relative aperture by this structure of the utility model On tool 9, the first drilling attachment 7 is conducted rotary force to the second drilling attachment 9 by casing 81, drives the second drilling attachment 9 Rotation, drill bit makes the pushing power of drill bit keep certain dynamics when processing metal, through the elastic force of spring 10, in this way it is avoided that Pushing is excessive to lead to bit damage, and when the metal of the bore of simultaneous processing 5mm or more, drill bit can be clamped in the first drill jig On tool 7, so that the transmitting of lower pressure is more direct, improve processing efficiency, just realize in this way avoid drill bit from damaging can with structure The technical effect leaned on has combined usually normal use.
