Description
Technical field
The utility model belongs to Machining Technology field, is related specifically to the erection unit of a kind of drill bit and sleeve.
Background technology
Conventional method together with being installed to sleeve by drill bit is as follows, is first inserted in sleeve by drill bit, then utilizes instrument by sleeve clamping, makes sleeve and drill bit close contact.Above-mentioned installation method not only complex procedures, operating difficulties, and be difficult to ensure the clamping force between drill bit and sleeve, be namely difficult to ensure that drill bit and sleeve are installed respond well.
Summary of the invention
The purpose of this utility model is that proposition is a kind of simple to operate, effectively can ensure the erection unit installing respond well drill bit and sleeve.
The erection unit of drill bit of the present utility model and sleeve comprises support, and described support is fixedly installed base, and described base is provided with open top and cross section is up big and down small cavity; This erection unit also comprises the mould can putting into described cavity, and described mould is inverted round table-like, and the middle part of mould is provided with the spacing hole with sleeve-shaped adaptation; Described mould is made up of at least two pieces of points of moulds, described point of mould with the central axis of mould for symmetry axis is symmetrical.
When installing drill bit and sleeve, first mould will be divided to combine, then put into cavity, and sleeve is put in the spacing hole of mould, then the bottom of drill bit is aimed at and is inserted partially in sleeve, finally utilize the instruments such as hammer percussive drill bit from top to bottom, while making drill bit enter sleeve inner downwards, band moving sleeve and mould move down, in the process that mould moves down together, its outer weekly assembly is subject to the inside pressure of cavity madial wall, thus is clamped gradually by sleeve.So just achieve simultaneously and drill bit is inserted in sleeve and by the object of sleeve clamping drill bit.Because the size of mould and cavity is all fixing, as long as therefore design the size relationship of mould and cavity, and ensure when mounted to make mould enter into the ad-hoc location of cavity downwards, can ensure that the clamping force that mould applies to sleeve is consistent, thus ensure that installation is respond well.After installing, mould is taken out in cavity, and split into a point mould, the drill bit assembled and sleeve can be taken out.
Further, convenient for moving back mould, the bottom of described cavity is provided with moves back mould through hole.When moving back mould, only need to stretch into along moving back mould through hole from the below of cavity with instruments such as iron rods, the drill bit of mould and inside thereof and sleeve are upwards ejected cavity.
Further, the driving mechanism that described support is also provided with upper punch and drives described upper punch to move up and down, described upper punch is positioned at the top of described cavity.Utilize the upper punch that automatically moves up and down to reduce hand labor intensity, and can ensure that the at every turn downward distance of upper punch is consistent, the distance namely promoting drill bit movement is downwards consistent, thus ensure that to install effect consistent.
The erection unit structure of drill bit of the present utility model and sleeve is simple, easy to operate, effectively can ensure to install effect consistent and good, have good practicality.

Accompanying drawing indicates: 1, support; 2, base; 3, cavity; 4, mould; 41, spacing hole; 5, mould is divided; 6, upper punch; 7, mould through hole is moved back; 8, drill bit; 9, sleeve.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the drill bit of the present embodiment and the erection unit of sleeve comprise support 1, and described support 1 is fixedly installed base 2, and described base 2 is provided with open top and cross section is up big and down small cavity 3; This erection unit also comprises the mould 4 can putting into described cavity 3, and described mould 4 is inverted round table-like, and the middle part of mould 4 is provided with the spacing hole 41 with sleeve-shaped adaptation; Described mould 4 is made up of four pieces of points of moulds 5, and described point of mould 5 is with the central axis of mould 4 for symmetry axis is symmetrical, and point mould 5 is in fan-shaped, and a point mould 5 is provided with arc (quadrant) breach near the position at mould 4 center.
The driving mechanism (driving mechanism does not draw in the drawings, and cylinder or bent axle can be adopted to be used as driving mechanism) that support 1 is also provided with upper punch 6 and drives described upper punch 6 to move up and down, described upper punch 6 is positioned at the top of described cavity 3.Utilize the upper punch 6 that automatically moves up and down to reduce hand labor intensity, and can ensure that the at every turn downward distance of upper punch 6 is consistent, the distance namely promoting drill bit movement is downwards consistent, thus ensure that to install effect consistent.
Convenient for moving back mould, the bottom of described cavity 3 is provided with moves back mould through hole 7.When moving back mould, only need to stretch into along moving back mould through hole 7 from the below of cavity 3 with instruments such as iron rods, the drill bit of mould 4 and inside thereof and sleeve are upwards ejected cavity 3.
When installing drill bit 8 with sleeve 9, first mould 5 will be divided to combine, then cavity 3 is put into, and sleeve 9 is put in the spacing hole 41 of mould 4, again the bottom of drill bit 8 aimed at and be inserted partially in sleeve 9, finally utilize the instruments such as hammer percussive drill bit 8 from top to bottom, while making drill bit 8 enter sleeve 9 inside downwards, band moving sleeve 9 and mould 4 move down together, in the process that mould 4 moves down, its outer weekly assembly is subject to the inside pressure of cavity 3 madial wall, thus is clamped gradually by sleeve 9.So just achieve simultaneously and drill bit 8 is inserted in sleeve 9 and sleeve 9 is clamped the object of drill bit 8.Because mould 4 and the size of cavity 3 are all fixing, as long as therefore design the size relationship of mould 4 and cavity 3, and ensure when mounted to make mould 4 enter into the ad-hoc location of cavity 3 downwards, can ensure that the clamping force that mould 4 applies to sleeve 9 is consistent, thus ensure that installation is respond well.After installing, mould 4 is taken out in cavity 3, and splits into point mould 5, the drill bit 8 assembled can be taken out with sleeve 9.
