Description
Technical field
The utility model belongs to drilling equipment technical field, is related to a kind of minor diameter circle class inner bore of part wall drilling blind hole to fill
Put.
Background technology
In machinery industry, there is the circle class part of many similar bearing top circles or revolving support, it is necessary to be bored on inner hole wall blind
Hole, or it is processed into screw.When this circle class inner bore of part is sufficiently large, bench drill periphery can be enclosed within to process, diameter of bore can be worked as
During less than bench drill height, cannot just machined.
Existing processing mode, usually drills to endoporus from cylindrical upper processing, then the welding plug on cylindrical again, comes
Realize final in inner hole wall presentation blind hole.Processing cost is this method increased, and some clients are present not on workpiece
Welding phenomena.
The content of the invention
The utility model is regarding to the issue above, there is provided a kind of minor diameter circle class inner bore of part wall drilling blind hole device, the device
Can effectively be drilled in minor diameter circle class inner bore of part wall.
According to the technical solution of the utility model：A kind of minor diameter circle class inner bore of part wall drilling blind hole device, its feature exists
In：Including support, bearing block is installed in described support one end, and the other end is rotated and sets the first chuck, and the first chuck lower end fixes the
One synchronous pulley, is rotated on bearing block and sets the second chuck, and the second synchronous pulley is installed on the diameter of axle of second chuck, synchronous
Band is tensioned on first synchronous pulley, the second synchronous pulley, and drill bit is installed in the second chuck lower end.
Used as further improvement of the utility model, the support includes vertical portion and is integrally connected to the vertical portion
Divide the upper mounting seat of upper end, the first chuck is installed in the upper mounting seat, and bearing block is installed on the lower end of the vertical portion.
Clamped as further improvement of the utility model, on first chuck and driving shaft, the first synchronous pulley are installed
It is installed on driving shaft.
It is of the present utility model to have technical effect that：The utility model can effectively in the inner hole wall of minor diameter circle class part
Upper drilling blind hole；The functions such as chamfering, deburring can be expanded using the covering device；It is easy-to-use using the covering device, carry significantly
High workload efficiency, reduces manufacturing cost；The covering device scope of application is wider, and the life-span is very long；The covering device simple structure, is manufactured into
This is relatively low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is left view of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including support 1, vertical portion 1-1, upper mounting seat 1-2, bearing block 2, the second synchronous pulley 3, second
Chuck 4, drill bit 5, Timing Belt 6, the first synchronous pulley 7, the first chuck 8, minor diameter circle class part 9 etc..
As shown in Figure 1, 2, the utility model is a kind of minor diameter circle class inner bore of part wall drilling blind hole device, including support 1,
Bearing block 2 is installed in the one end of the support 1, and the other end is rotated and sets the first chuck 8, and the first Timing Belt is fixed in the lower end of the first chuck 8
Wheel 7, is rotated on bearing block 2 and sets the second chuck 4, and the second synchronous pulley 3, Timing Belt 6 are installed on the diameter of axle of second chuck 4
It is tensioned on first synchronous pulley 7, the second synchronous pulley 3, drill bit 5 is installed in the lower end of the second chuck 4.
Support 1 includes vertical portion 1-1 and is integrally connected to the upper mounting seat 1-2 of the vertical portion 1-1 upper ends, first
Chuck 8 is installed on the upper mounting seat 1-2, and bearing block 2 is installed on the lower end of the vertical portion 1-1.
Clamped on first chuck 8 and driving shaft is installed, the first synchronous pulley 7 is installed on driving shaft.
The utility model realized by reequiping bench drill, and the is installed by main shaft using the first chuck 8 of former bench drill
One synchronous pulley 7, the second synchronous pulley 3 is transferred to by Timing Belt 6 by rotary power, and support 1 is bolted to by holding
In former table drill main shaft excircle of sleeve, support 1 can simultaneously move up and down with rack sleeve；Second synchronous pulley 2 drives second to press from both sides
First 4, the drill bit or chamfer drill of the diameter of needs can be clamped in the second chuck 4, whole support 1 forms cantilever design.Due to outstanding
The small volume of arm mechanism, can stretch into the endoporus of minor diameter circle class part 9, while being transmitted by the power of Timing Belt 6, make
The lower section chuck rotation of cantilever mechanism, clamps the drill bit of diameter in need in chuck, can thus realize drilling function, then profit
With the down operation handle of former bench drill, the very easily drilling blind hole on the inner hole wall of minor diameter circle class part.Bored by changing
Head is chmfer bit, can also realize the functions such as the orifice chamfer deburring of inner hole wall aperture.
