Abstract
The invention belongs to the field of machining of control assemblies and particularly discloses a pin hole drilling device for a control rod assembly. The pin hole drilling device comprises a drill machine, a drill chuck, a lengthening drill locking rod and a support. The drill machine is fixedly connected with the support. The motor end of the drill machine is fixedly connected with the upper end of the drill chuck. The lower end of the drill chuck is fixedly connected with the upper end of the lengthening drill locking rod. The lengthening drill locking rod comprises an outer sleeve, a locknut, an open chuck, a drill and an inner sleeve. The upper end of the outer sleeve is fixedly connected with the lower end of the drill chuck, and the inner sleeve is arranged in the lower end of the outer sleeve. The open chuck is arranged at an opening of the inner sleeve and an opening of the outer sleeve. The drill penetrates through the open chuck to be fixedly connected with the inner sleeve. The locknut is arranged outside the open chuck and the wall of the outer sleeve. The open chuck is locked by the locknut, and the drill is also locked by the locknut. The pin hole drilling device can effectively avoid bounce caused when a super-long drill is used, and the drilling hole diameter can be accurately controlled.
Description
Technical field
The invention belongs to control assembly manufacture field, be specifically related to a kind of C&P systems pin-and-hole and join boring device.
Background technology
In prior art, in the production process of AFA3G C&P systems, it is necessary to it is 2.4mm that each finger bar at connection handle bores a diameter with each control rod end plug place of cooperation, and the degree of depth is the stop pin nail of 3.5-4.0mm.Control when assembly inner ring refers to lever pin nail because of main axle moving travel limit directly the drill chuck on main shaft to clamp bit bore joining brill, then have employed special-purpose lengthening bar drill chuck during boring, the extension bar of drill chuck is owing to manufacturing factor, mechanical property, mode when locking drill bit when clamping drill bit is unreasonable and must firmly lock, otherwise when boring can there is play in drill bit, and use overlong time, extension bar is caused to bend, beat increase, drill bit and main shaft axiality is made well not to keep, and drill bit needs frequently to change the drill bit of different size when boring diverse location, and use special-purpose lengthening drill chuck to stretch out long, in addition bore when inner ring refers to lever pin nail and need to use longer drill bit, the increase of beating of drill bit simultaneously, have impact on borehole accuracy.
Summary of the invention
It is an object of the invention to provide a kind of it can be avoided that the C&P systems pin-and-hole that overlength drill bit causes aperture of beating, accurately control joins boring device.
Realize the technical scheme of the object of the invention:
A kind of C&P systems pin-and-hole joins boring device, and it includes drilling machine, drill chuck, lengthening drill bit check lock lever and bearing；Drilling machine is fixing with bearing to be connected, and the motor side of drilling machine is fixing with the upper end of drill chuck to be connected, and the lower end of drill chuck is fixing with the upper end of lengthening drill bit check lock lever to be connected.
Described lengthening drill bit check lock lever includes trocar sheath, locking nut, opening chuck, drill bit and inner sleeve；The upper end of trocar sheath is fixing with the lower end of drill chuck to be connected, and is provided with inner sleeve inside the lower end of trocar sheath；The opening part of inner sleeve and trocar sheath is provided with opening chuck；Drill bit is connected through opening chuck and inner sleeve are fixing；Opening chuck is provided externally with locking nut with trocar sheath tube wall；Opening chuck is locked by locking nut, and is locked by drill bit.
The diameter of described drill bit is 2.4mm, and length is 5.0～10.0mm.
The Advantageous Effects of the present invention is in that:
(1) a kind of C&P systems pin-and-hole provided by the present invention joins boring device by adopting the design of trocar sheath, beginning jaws, extends the effective length of drill bit, it is to avoid use longer drill bit to affect service life；
(2) by being locked by drill bit so that drill bit is not susceptible to distortion and beats, the aperture degree of accuracy of the required stop pin nail of processing is substantially increased.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As it is shown in figure 1, a kind of C&P systems pin-and-hole provided by the present invention is joined boring device and is included drilling machine 1, drill chuck 2, lengthening drill bit check lock lever 3 and bearing 4.Drilling machine 1 is fixing with bearing 4 to be connected.The motor side of drilling machine 1 is fixing with the upper end of drill chuck 2 to be connected, and the lower end of drill chuck 2 is fixing with the upper end of lengthening drill bit check lock lever 3 to be connected.
As in figure 2 it is shown, lengthening drill bit check lock lever 3 includes trocar sheath 5, locking nut 6, opening chuck 7, drill bit 8 and inner sleeve 9.The upper end of trocar sheath 1 is fixing with the lower end of drill chuck 2 to be connected, and is provided with inner sleeve 9 inside the lower end of trocar sheath 1.The opening part of inner sleeve 9 and trocar sheath 1 is provided with opening chuck 7.Drill bit 8 is connected through opening chuck 7 is fixing with inner sleeve 9.Opening chuck 7 is provided externally with locking nut 6 with trocar sheath 1 tube wall.Opening chuck 7 is locked by locking nut 6, and is locked by drill bit 8.
Trocar sheath 1 extends the effective length of drill bit 8, and owing to drill bit 8 is locked so that drill bit 8 is not susceptible to distortion and beats, and substantially increases the degree of accuracy in processing aperture.It is 2.4mm owing to needing at control rod end plug cooperation place one diameter of brill to be processed, the degree of depth is the stop pin nail of 3.5-4.0mm, and the diameter therefore choosing drill bit 8 is 2.4mm, and length is 5.0mm～10.0mm, in the present embodiment, the drill bit 8 that length is 5.0mm can meet requirement.
Above in conjunction with drawings and Examples, the present invention is explained in detail, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, it is also possible under the premise without departing from present inventive concept, make various change.The content not being described in detail in the present invention all can adopt prior art.
