In the prior art, the U of patent CN 204556950 provide a kind of double speed band tooth for astronomical telescope and focused
Device, including rack, gear, pinion stand, focusing mount, focusing drum and focusing handwheel, it designs and produces into focusing drum more outside inner circle
Side shape, focusing mount is designed and produced into cylindrical inner polygon shape, focusing drum is engaged with focusing mount, so as to limit focusing drum
Radial rotating between focusing mount, while engaged by gear of focusing with the rack on focusing drum, driving focusing drum is being focused
Seat axis movement, reaches focusing purpose.The utility model structure is relatively complicated, and focusing mode is still manual focusing, it is difficult to
Accomplish stable focus.
The content of the invention
The purpose of this utility model is to provide a kind of simple, stable compound focusing device.
For achieving the above object, technical scheme is used by the utility model：A kind of telescope compound focusing dress
Put, including focusing mount and the focusing drum being fixed on focusing mount, the focusing drum includes the inner cylinder and outer barrel being coaxially disposed, described
Fixation sets multiple sliding blocks on the outer wall side face of inner cylinder, offers chute on the outer tube inner wall relative with sliding block, the inner cylinder it is outer
Leading screw is connected with by feed screw nut at the top of wall, the feed screw nut is rigidly connected with inner cylinder, and the both ends of leading screw are consolidated by bearing
It is scheduled on the inwall of outer barrel, is provided with motor in the focusing base, the motor is connected by shaft coupling with leading screw.
Preferably, in addition to magnetic grid reading plotter, the magnetic grid reading plotter are between bearing and close including two
The limit switch of bearing, the magnetic railings ruler between limit switch and the magnetic grid reading head being fixed on feed screw nut, it is described
Limit switch and magnetic grid bar are fixed on the inwall of outer barrel,
Preferably, the sliding block number corresponds with chute number, and sliding block number is at least 1.
Preferably, in addition to for receiving the magnetic grid reading plotter signal controller 14 that simultaneously energy controlled motor 9 drives.
The beneficial effects of the utility model embody a concentrated reflection of, simple in construction, and focusing is stable.Specifically, the utility model
It is engaged by the sliding block being arranged on inner cylinder with the chute on outer barrel, makes inner cylinder movement on the axis of outer barrel more accurate, keep away
Exempt from focussing process because inner cylinder skew and caused by focus it is inaccurate, in use, rotated by motor driving leading screw, and further
Inner cylinder is driven to be moved on the axis of outer barrel by feed screw nut, so as to realize stable focusing, compared with prior art, this practicality is new
Type is simple in construction, easy to use, and focusing is more stable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the scheme of installation of inner cylinder and outer barrel in the utility model.
Embodiment
The utility model is expanded on further below in conjunction with the accompanying drawings.
As shown in Figure 1-2, a kind of telescope compound focusing device, including focusing mount 1 and the focusing that is fixed on focusing mount 1
Cylinder, the focusing drum include the inner cylinder 2 and outer barrel 3 being coaxially disposed, are fixed on the outer wall side face of the inner cylinder 2 and set multiple sliding blocks 4,
Chute 5 is offered on the inwall of outer barrel 3 relative with sliding block 4, the outer wall top of the inner cylinder 2 is connected with silk by feed screw nut 6
Thick stick 7, the feed screw nut 6 are rigidly connected with inner cylinder 2, and the both ends of leading screw 7 are fixed on by bearing 8 on the inwall of outer barrel 3, described
Motor 9 is provided with focusing mount 1, the motor 9 is connected by shaft coupling 10 with leading screw 7.
Further, in addition to magnetic grid reading plotter, the magnetic grid reading plotter include two between bearing 8 and leaned on
It is paraxial to hold 8 limit switch 11, the magnetic railings ruler 12 between limit switch 11 and the magnetic grid reading being fixed on feed screw nut 6
Several first 13, the limit switch 11 and magnetic railings ruler 12 are fixed on the inwall of outer barrel 3, the magnetic railings ruler 12 and magnetic grid reading head 13
Relatively.The characteristics of magnetic grid reading plotter is used in precision instrument in the prior art, has accuracy of reading, and cost is lower,
This is not repeated.So, the magnetic grid reading head 13 on feed screw nut 6 can carry out essence according to the relative position of itself and magnetic railings ruler 12
True reading, operator can accurately know focussing distance according to read-out number, and it is more accurate to focus.Limit switch 11 is to inner cylinder 2
Focussing distance carry out it is spacing, prevent because inner cylinder 2 move it is excessive and caused by damage.
Further, the number of sliding block 4 corresponds with the number of chute 5, and the number of sliding block 4 is at least 1, so, further
Ensure that inner cylinder 2 has more preferable linearity relative to the axis of outer barrel 3, it is mobile more accurate.
Further, in addition to for receiving the magnetic grid reading plotter signal controller 14 that simultaneously energy controlled motor 9 drives, this
Sample, by way of reading control, operation is more simply, conveniently.
The utility model when in use, by the controlled motor 9 of controller 14, to drive leading screw 7 to rotate, matches with leading screw 7
The feed screw nut 6 of conjunction is for linear motion on leading screw 7, so as to drive coupled inner cylinder 2 to make line on the axis of outer barrel 3
Property movement, reach focusing purpose, in focussing process, magnetic grid reading plotter can according to the motion of feed screw nut 6, monitor on-line
The distance of movement 2 of inner cylinder 2, the displacement signal that operator feeds back according to magnetic grid reading plotter is set to make tune further to the accurate adjustment of inner cylinder 2
It is burnt more accurate.The middle kind of drive using rack-and-pinion, lead screw transmission are more stable compared with prior art.
Although the embodiment of the present invention is the foregoing described, it will be appreciated by those of skill in the art that not
On the premise of the principle and essence of the present invention, various changes or modifications can be made to these embodiments, but these become
More protection scope of the present invention is each fallen within modification.
