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. 1-3, a four-axis synchronous gripper for maintaining a watch comprises a gripper base 1, a spring 2 is fixedly mounted at the top end of the gripper base 1, a gripping platform 3 is fixedly connected to the top end of the spring 2, and a user can randomly adjust the angle of the gripping platform 3 according to the needs when using the gripper, so that the watch is more convenient to maintain, and the maintenance efficiency is improved.
An adjusting rotating shaft 4 is movably connected in the middle of the clamping platform 3, an adjusting shaft gear 5 is fixedly connected on the back of the adjusting rotating shaft 4, bevel teeth are arranged on the outer side of the adjusting shaft gear 5 and meshed with a synchronous gear 6 through the bevel teeth, bevel teeth are arranged on two sides of the synchronous gear 6 and meshed with a chuck gear 7 through the bevel teeth, a chuck rotating shaft 8 is fixedly connected on the front of the chuck gear 7, the rotating directions of threads on the two chuck rotating shafts 8 which are opposite to each other are opposite, so that when the adjusting rotating shaft 4 is rotated and the chuck gear 7 is driven to rotate, the two opposite chucks 9 can simultaneously move towards the middle of the clamping platform 3 along the chuck rotating shafts 8 or simultaneously move towards two sides of the clamping platform 3, so that the four chucks 9 can perform clamping or loosening actions along with the control of the adjusting rotating shaft 4, a thread groove is arranged in the middle of the chuck rotating shaft 8 and is in threaded connection with the chucks 9 through the thread groove, the top end of the chuck 9 is bent towards the central position of the clamping platform 3, and the radian shape is adapted to the watch dial, so that the chuck 9 can better fix the dial when moving inwards for clamping, the front surface of the position where the chuck 9 is connected with the chuck rotating shaft 8 is fixedly provided with a rotary coil spring 10, the rotary coil spring 10 has the tendency that the chuck gear 7 rotates towards the central position of the clamping platform 3 under the tensioning state, so that the chuck 9 always has the tendency of inclining inwards in the moving process, the top surface of the clamping platform 3 is provided with a chuck groove 11, the chuck groove 11 has the radian bending from four corners to the center, so that the chuck 9 always has the tendency of rotating towards the central position of the clamping platform 3 under the elastic force action of the rotary coil spring 10 in the moving process of clamping inwards, and the chuck 9 gradually rotates inwards in the process of clamping inwards under the guiding action, so that a user can pass through the rotation degree of the chuck 9, and the clamping degree of the chuck 9 is judged according to the contact condition of the top end of the chuck 9 and the watch dial, so that the problem of overlarge clamping force caused by the fact that a user cannot judge the clamping force of the clamper is avoided, and the secondary damage rate of the dial is reduced.
The use method (working principle) of the invention is as follows:
when in use, the rotating shaft 4 is rotated to enable the chucks 9 to be positioned at the four corners of the clamping platform 3, the chucks 9 are in a vertically upward opening state at the moment, the dial is placed at the central position of the clamping platform 3, the rotating shaft 4 is reversely rotated to enable the chucks 9 to move inwards and gradually tighten, in the inward moving process, the chucks 9 have a trend of rotating towards the center of the clamping platform 3 under the elastic force of the rotary coil spring 10, as the chuck groove 11 at the top surface of the clamping platform 3 is in a radian bending from four corners to the center, the chucks 9 rotate gradually towards the central position in the inward moving process, a user can judge the clamping degree of the chucks 9 by observing the contact condition of the top end of the chucks 9 and the dial plate of the watch, thereby avoiding the secondary damage of the dial plate caused by the overlarge clamping force of the chucks 9, after the dial plate is clamped, the user can press the springs 2 at the four corners of the clamping platform 3 according to own needs, therefore, the angle of the dial plate can be adjusted at will to adapt to the maintenance position of the user, the clamping device is more convenient, and the maintenance efficiency of the user is greatly improved.
