Technical field
The present invention relates to metal cutting field, refer in particular to a kind of emery wheel case automatic door device.
Background technology
Traditional double-ended grinding machine in grinding process mill spindle outside emery wheel case, grinding tool on mill put into by the part be ground, mill rotarily drives part and enter grinding between emery wheel case and two abrasive wheel end faces from emery wheel case, and limit broken takes emery wheel case out of, such periodic duty.After part milled, then open discharge door, slowly blanking after rotary grinding disk, this type of Machinery Design by hand, when grinding, emery wheel case can not close grinding, affects operator's operating environment and personal safety, haves much room for improvement.
Therefore, the present inventor makes further research this, and develop a kind of emery wheel case automatic door device, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of emery wheel case automatic door device, not only serve the effect of protection operator, and achieve the door with mechanical means automatic switch emery wheel case.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of emery wheel case automatic door device, comprises transmission mechanism, double rocker mechanism, emery wheel door; Described transmission mechanism and double rocker mechanism are connected, and emery wheel door is arranged on double rocker mechanism.
Further, described transmission mechanism comprises motor, pivoted housing, flat key, worm screw, worm sector; Pivoted housing is connected with motor linkage, and pivoted housing and worm screw link together by flat key, and worm sector is connected with worm engaging, and worm sector and double rocker mechanism are connected.
Further, endplay device comprises four rocking bars, power transmission shaft, rotating shaft stake, and power transmission shaft is arranged between rotating shaft stake, and power transmission shaft and worm sector are connected, and rocking bar is all articulated in rotating shaft stake.
Further, described double rocker mechanism also comprises two emery wheel chamber door bars be articulated on rocking bar, and the both sides up and down that emery wheel chamber door bar is separately positioned on emery wheel door are parallel with power transmission shaft.
Further, described emery wheel door also comprises door pocket, and emery wheel chamber door bar is socketed in door pocket.
After adopting such scheme, the present invention compared with prior art, has the following advantages:
1. serve the effect of protection operator, achieve the door with mechanical means automatic switch emery wheel case.
2. utilize Worm Wheel System self-locking character, when making emery wheel door open or close, not because pts wt rotates automatically.
3. worm screw one end is connected directly between on motor shaft head, and the other end is arranged on bracket bearing, and structure is simple, low cost of manufacture.
4. the both sides of the articulated section of emery wheel chamber door bar and rocking bar are provided with door pocket, are conducive to the relative position regulating rocking bar and emery wheel chamber door bar.
5. design identical double rocker mechanism about emery wheel case, be conducive to motion flexibly, stressed good.

Label declaration
Casing 1, motor 2, pivoted housing 3, flat key 4, worm screw 5, worm sector 6, power transmission shaft 7, rotating shaft stake 8, rocking bar 9, emery wheel chamber door bar 10, emery wheel door 11, door pocket 12.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
As shown in the figure, a kind of emery wheel case automatic door device that the present invention discloses, comprises casing 1, and is arranged on the motor 2 in casing 1, pivoted housing 3, flat key 4, worm screw 5, worm sector 6, bracket bearing and power transmission shaft 7; Also be included in the rotating shaft stake 8 outside casing 1, rocking bar 9, emery wheel chamber door bar 10, emery wheel door 11.
Wherein pivoted housing 3 and motor 2 are connected, and pivoted housing 3 and worm screw 5 link together by flat key 4, and worm sector 6 and worm screw 5 are connected, and worm sector 6 and power transmission shaft 7 are connected, and worm screw 5 is connected on bracket bearing.
Described rocking bar 9 has four, and be all arranged in the rotating shaft stake 8 outside casing 1, wherein two rocking bars 9 are connected with power transmission shaft 7 by flat key 4, and these two rocking bars 9 need to bear more load as drive crank, compares two remaining rocking bars 9 thicker; Described emery wheel chamber door bar 10 has two, is separately positioned between upper and lower two groups of rocking bars 9, parallel with power transmission shaft 7.
Described emery wheel door 11 is also provided with door pocket 12, and two emery wheel chamber door bars 10 are socketed in emery wheel door about 11 both sides by door pocket 12, emery wheel chamber door bar 10 and door pocket 12 are fixed with bolt.Like this when rocking bar 9 rotates for round dot with rotating shaft stake 8, emery wheel door 11 also can move thereupon.
Operation principle of the present invention is:
Suppose that emery wheel chamber door is in closed condition, when motor 2 starts, pivoted housing 3 is driven to rotate, pivoted housing 3 drives worm screw 5 to rotate by the flat key 4 be provided at its inner portion, thus worm sector 6 is rotated, the power transmission shaft 7 being arranged on worm sector 6 circle centre position rotates thereupon, and the rocking bar 9 be articulated on power transmission shaft 7 lifts, emery wheel door 11 and the rocking bar 9 be articulated in rotating shaft stake 8 are also lifted thereupon, and emery wheel chamber door is opened.
After part enters emery wheel case, control motor 2 rotation by Numeric Control Technology and emery wheel chamber door is closed, when after part milled, then open, repeat above-mentioned steps.
Above are only specific embodiments of the invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
