Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution: the utility model provides a gear locking mechanism that digit control machine tool was used, including lathe main part 1 and the guard gate 2 of setting on lathe main part 1, the mounting groove that holds guard gate 2 is seted up to the terminal surface before lathe main part 1, the right-hand member at the mounting groove is installed in 7 rotations of pivot in the one end of guard gate 2, the fixed card strip 4 that is provided with in other end outer wall middle part of guard gate 2, the fixed door handle 3 that is provided with in upper end that guard gate 2 outer wall is located card strip 4, the upper right end of mounting groove is provided with 7 matched with gear locking mechanism in pivot, lathe main part 1 is located the fixed mounting bracket 5 that is provided with in right-hand member middle part of mounting groove, 5 cross sections of mounting bracket are T shape structure, 6 one end of lock block is passed through the round pin axle and is rotated the horizontal part of installing at

mounting bracket

5, 6 other ends of lock block contradicts at the vertical part of mounting bracket 5, lock block 6 sets up to be circular-arc triangle-shaped structure in the bottom, card strip 4 card is equipped with between mounting bracket 5 and the lock block 6. Locking piece 6 is under natural state, because its self gravity factor can deflect downwards and contradict at the vertical part of mounting bracket 5, can play spacing fixed effect to calorie strip 4 to can play the effect of further locking to guard gate 2.

As shown in fig. 1 and 2, a double-cylindrical cavity is formed in the upper right end of the machine tool main body 1, which is located in the mounting groove, a driving wheel 8, a driven wheel 9 and a rack 10 are arranged in the double-cylindrical cavity, the driven wheel 9 is rotatably mounted in the double-cylindrical cavity through a central shaft, the driving wheel 8 and the rack 10 are respectively meshed with the driven wheel 9, and the top of the rotating shaft 7 extends into the double-cylindrical cavity and is coaxially fixed with the driving wheel. When the protective door is opened, the rotating shaft 7 drives the driving wheel 8 to rotate anticlockwise along with the protective door 2, and the driving wheel 8 acts on the driven wheel 9, so that the driven wheel 9 rotates clockwise and acts on the rack 10, and the rack 10 moves towards the direction of the second magnetic block 12; when pulling force to the protective door 2 is cancelled, under the action of repulsive force between the first magnetic block 11 and the second magnetic block 12 of the same name, the rack 10 moves towards the direction of the cushion block 13 and acts on the driven wheel 9, so that the driven wheel 9 rotates anticlockwise, and the driven wheel 9 acts on the driving wheel 8, so that the driving wheel 8 drives the rotating shaft 7 to rotate clockwise, and the effect of automatically closing the protective door 2 is achieved.

As shown in fig. 2, a rectangular movable cavity is formed in the left side of the double-column cavity, a rack 10 is slidably mounted in the rectangular movable cavity, a first magnetic block 11 is fixedly arranged at one end, away from a driven wheel 9, of the rack 10, a second magnetic block 12 is fixedly arranged at one side of the rectangular movable cavity, a cushion block 13 is fixedly bonded at the other side of the rectangular movable cavity, and the first magnetic block 11 and the second magnetic block 12 are arranged in a manner that like magnetic poles are opposite to each other. This cushion 13 is the block rubber, can play the effect of shock attenuation buffering to rack 10.

The working principle is as follows: in practical use, one hand takes the locking block 6 upwards, the other hand holds the handle 3 and pulls the protective door outwards, at the moment, the rotating shaft 7 drives the driving wheel 8 to rotate anticlockwise along with the protective door 2, the driving wheel 8 acts on the driven wheel 9, the driven wheel 9 rotates clockwise and acts on the rack 10, and the rack 10 moves towards the direction of the second magnetic block 12; and when withdrawing the pulling force to guard gate 2, under the repulsion effect between the first magnetic path 11 of the same name and second magnetic path 12, rack 10 removes and acts on from driving wheel 9 towards the direction of cushion 13, make from driving wheel 9 carry out anticlockwise rotation, because from driving wheel 9 action wheel 8, make action wheel 8 drive pivot 7 carry out clockwise rotation, in order to reach guard gate 2 self-closing's effect, meanwhile, locking piece 6 is under natural state, because its self gravity factor can deflect downwards and contradict at the vertical part of mounting bracket 5, can play spacing fixed effect to card strip 4, thereby can play the effect of further locking to guard gate 2.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
