Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of microswitch trigger cam adjustment device its
Including power transmission shaft 1 and the two set adjusting parts that are arranged on power transmission shaft 1, this two sets adjusting part includes the
One cover plate the 2, second cover plate the 3, first cam 4 and the second cam 5, described first cam 4 and the second cam
5 recline is arranged between described first cover plate 2 and the second cover plate 3, described first cam 4 and the second cam 5
On be provided with a cam surface, the lower section of described first cam 4 and the second cam 5 is fixed with microswitch 6,
Described power transmission shaft 1 is arranged through first cover plate the 2, second cover plate the 3, first cam 4 and the second cam 5, and
Described power transmission shaft 1 cross section is regular hexagon, corresponding to described first cover plate 2 and the center of the second cover plate 3
Offer the regular hexagon hole coordinating described power transmission shaft 1 to arrange, described power transmission shaft 1 by regular hexagon hole in
Described first cover plate 2 and the second cover plate 3 are in transmission connection.
The outside of described first cam 4 and the second cam 5 is extended with the biography of the structure being integrated with corresponding cam
Moving gear 7, is extended with inner ring 8 at the medial center of described first cover plate 2 and the second cover plate 3, and described first
Cam 4 and the second cam 5 are rotatablely arranged at outside described inner ring 8 by the endoporus of travelling gear 7.Institute
State the mounting groove 9 being provided with an indent outside the first cover plate 2 and the second cover plate 3, in described mounting groove 9
Portion offers breach in being provided with two ribs 10, and the mounting groove 9 between said two rib 10, described
Mounting groove 9 is rotatably mounted with worm screw 11 between said two rib 10, and described worm screw 11 passes through institute
State breach to be meshed with described travelling gear 7.
During work, power transmission shaft 1 rotates, and drives the first cover plate 2 and the second cover plate 3 to rotate simultaneously, because the
The rotating thus drive both to rotate, because of worm screw 11 by worm screws 11 installed above of one cover plate 2 and the second cover plate 3
