A kind of emery wheel case automatic door device
Technical field
The present invention relates to the 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 the emery wheel case; Put into grinding tool on the mill by the part of grinding; The mill rotation drives part and outside the emery wheel case, gets into grinding between emery wheel case and two abrasive wheel end faces, and the limit broken is taken emery wheel case, periodic duty like this out of.After the part mill is good, open discharge door by hand again, slowly blanking behind the rotary grinding disk, this type of Machinery Design, when grinding, the emery wheel case can not seal grinding, influences operator's operating environment and personal safety, haves much room for improvement.
Therefore, the inventor does further research to this, develops a kind of emery wheel case automatic door device, and 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 played protection operator's effect, and realized door with mechanical automatic switch emery wheel case.
To achieve these goals, technical scheme of the present invention is following:
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 the emery wheel door is installed on the 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 flat key links together pivoted housing and worm screw, 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, and the rotating shaft stake, power transmission shaft is arranged between the rotating shaft stake, and power transmission shaft and worm sector be connected, and rocking bar all is articulated in the rotating shaft stake.
Further, described double rocker mechanism also comprises two emery wheel chamber door bars that are articulated on the rocking bar, and emery wheel chamber door bar to be separately positioned on the both sides up and down of emery wheel door parallel with power transmission shaft.
Further, described emery wheel door also comprises door pocket, and emery wheel chamber door bar is socketed in the door pocket.
After adopting such scheme, the present invention compared with prior art has the following advantages:
1. played protection operator's effect, realized door with mechanical automatic switch emery wheel case.
2. utilize worm and gear transmission self-locking character, when making the emery wheel door open or close, do not rotate etc. because of pts wt is automatic.
3. worm screw one end directly is connected on the motor shaft head, and the other end is installed on the bracket bearing, and is simple in structure, 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, help regulating the relative position of rocking bar and emery wheel chamber door bar.
5. the identical double rocker mechanism of design about the emery wheel case helps motion flexibly, and is 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.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described.
A kind of emery wheel case automatic door device as shown in the figure, that the present invention discloses comprises casing 1 and is arranged on the motor 2 in the 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 the casing 1, rocking bar 9, emery wheel chamber door bar 10, emery wheel door 11.
Wherein pivoted housing 3 is connected with motor 2, and flat key 4 links together pivoted housing 3 and worm screw 5, and worm sector 6 is connected with worm screw 5, and worm sector 6 is connected with power transmission shaft 7, and worm screw 5 is connected on the bracket bearing.
Described rocking bar 9 has four, all is arranged in the rotating shaft stake 8 outside the casing 1, and wherein two rocking bars 9 are connected with power transmission shaft 7 through flat key 4, and these two rocking bars 9 need be born more load as drive crank, and it is thicker to compare two remaining rocking bars 9; Described emery wheel chamber door bar 10 has two, is separately positioned on up and down between two groups of rocking bars 9, and is parallel with power transmission shaft 7.
Also be provided with 12, two emery wheel chamber doors of door pocket bar 10 on the described emery wheel door 11 and be socketed in the emery wheel door through door pocket 12 about in the of 11 both sides, with bolt that emery wheel chamber door bar 10 is fixing with door pocket 12.When rocking bar 9 was the round dot rotation with rotating shaft stake 8, emery wheel door 11 also can movement therewith like this.
Operation principle of the present invention is:
Suppose that the emery wheel chamber door is in closed condition,, drive pivoted housing 3 and rotate when motor 2 starts; Pivoted housing 3 drives worm screw 5 rotations through the flat key 4 of the portion of setting within it; Thereby make worm sector 6 rotate, the power transmission shaft 7 that is arranged on worm sector 6 circle centre positions rotates thereupon, and the rocking bar 9 that is articulated on the power transmission shaft 7 lifts; Make emery wheel door 11 and the rocking bar 9 that is articulated in the rotating shaft stake 8 also lift, the emery wheel chamber door is opened thereupon.
After part gets into the emery wheel case, the emery wheel chamber door is closed, after the part mill is good, open again, repeat above-mentioned steps through 2 rotations of Numeric Control Technology control motor.
Above-mentionedly be merely specific embodiment of the present invention, but design concept of the present invention is not limited thereto, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
