[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.
[0020] like Figure 1-3 As shown, a horizontal fine-tuning structure of a precision mechanical equipment includes a base 1 and an upper connecting frame 2, the base 1 and the upper connecting frame 2 are arranged correspondingly up and down, an anti-deflection structure 3 is symmetrically arranged between the base 1 and the upper connecting frame 2, an adjustment structure 4 is arranged between the base 1 and the upper connecting frame 2, the adjustment structure 4 includes a stud 41, a rotating cylinder 42 is provided on the top of the base 1, the bottom of the stud 41 is rotatably connected to the rotating cylinder 42, a threaded cylinder 46 is provided on the bottom of the upper connecting frame 2, the top of the stud 41 is threadedly connected to the inside of the rotating cylinder 42, and the top and bottom of the side wall of the stud 41 are respectively provided with a first nut 47 and a second nut 48.
[0021] When the first nut 47 is screwed to the bottom end of the upper connecting frame 2 and the second nut 48 is screwed to the top end of the base 1, the stud 41 is locked. The novel structure is simple, and the first nut 47 and the second nut 48 serve as both an adjusting component and a locking component, which is convenient for adjustment. Moreover, during adjustment, neither the base 1 nor the upper connecting frame 2 rotates, and the adjustment resistance is small.
[0022] like Figure 1 and 3 As shown, the base 1 includes a first U-shaped plate 11 and a base plate 12, the bottom end of the first U-shaped plate 11 is fixedly connected to the top end of the base plate 12, the upper connecting frame 2 includes a second U-shaped plate 21, the top end of the second U-shaped plate 21 is symmetrically provided with a connecting plate 22, and the interior of the second U-shaped plate 21 is fixedly connected with equidistantly distributed reinforcing ribs 23.
[0023] According to the above structure, the reinforcing ribs 23 serve to strengthen the structural strength of the second U-shaped plate 21 , and the base plate 12 serves to increase the contact area with the ground and reduce the pressure.
[0024] like Figure 4As shown, the anti-deflection structure 3 includes two connecting seats 31 fixedly connected to the top end of the first U-shaped plate 11 and the bottom end of the second U-shaped plate 21 respectively. The connecting seat 31 is internally rotatably connected with a connecting rod 32, and one end of the two connecting rods 32 is rotatably connected.
[0025] According to the above structure, during adjustment, the ends of the two connecting rods 32 rotate, and the anti-deflection structure 3 can prevent the base 1 and the upper connecting frame 2 from rotating relative to each other, thereby preventing dislocation.
[0026] like Figure 3 As shown, a rotating cylinder 42 is fixedly connected to the middle part of the first U-shaped plate 11, and a cylindrical head 43 is rotatably connected to the inside of the rotating cylinder 42. The bottom end of the stud 41 is fixedly connected to the cylindrical head 43. The bottom end of the cylindrical head 43 and the bottom end of the inner wall of the rotating cylinder 42 are both provided with annular grooves 44. Evenly distributed balls 45 are rollingly arranged between the two annular grooves 44. A concave cavity 49 is provided at the top of the stud 41. The inside of the concave cavity 49 is slidably connected to an anti-slip rod 410, and the top of the anti-slip rod 410 passes through the top of the threaded cylinder 46.
[0027] According to the above structure, during adjustment, the cylindrical head 43 rotates inside the rotating drum 42, and the ball 45 arranged between the cylindrical head 43 and the rotating drum 42 plays a role in reducing friction, reducing the resistance to the rotation of the stud 41, and facilitating the rotation and adjustment of the stud 41.
[0028] like Figure 3 As shown, the top and bottom ends of the anti-slip rod 410 are fixedly connected to a circular plate 411 , the top of the concave cavity 49 is provided with a circular ring 412 , and the anti-slip rod 410 passes through the circular ring 412 .
[0029] According to the above structure, when the top of the stud 41 rotates to the bottom of the threaded barrel 46, the two circular plates 411 move to the top of the threaded barrel 46 and the bottom of the ring 412 respectively, thereby preventing the stud 41 from separating from the threaded barrel 46.
[0030] The working principle of the present invention is as follows: when adjusting, the top end of the upper connecting frame 2 is fixedly connected to the bottom end of the mechanical equipment, the first nut 47 is screwed downward, and the second nut 48 is screwed upward. When the first nut 47 and the second nut 48 are in contact with each other, the two are limited to each other. At this time, the first nut 47 is screwed downward, and the first nut 47 will not rotate downward, which will drive the stud 41 to rotate clockwise. The stud 41 moves downward along the threaded barrel 46, thereby increasing the distance between the base 1 and the upper connecting frame 2. Similarly, screwing the second nut 48 upward will shorten the distance between the upper connecting frame 2 and the base 1. After the adjustment is completed, the first nut 47 is screwed upward and the second nut 48 is screwed downward. When the first nut 47 is screwed to the upper connecting frame 2, the first nut 47 is screwed to the upper connecting frame 2. When the bottom end of the stud 41 is rotated and the second nut 48 is screwed to the top end of the base 1, the stud 41 is locked. The novel structure is simple. The first nut 47 and the second nut 48 serve as both an adjusting component and a locking component, which is convenient for adjustment. Moreover, during adjustment, the base 1 and the upper connecting frame 2 do not rotate, and the adjustment resistance is small. During adjustment, the cylindrical head 43 rotates inside the rotating cylinder 42. The ball 45 arranged between the cylindrical head 43 and the rotating cylinder 42 plays a role in reducing friction, thereby reducing the resistance to rotation of the stud 41 and facilitating the rotation of the adjustment stud 41. When the top of the stud 41 rotates to the bottom of the threaded cylinder 46, the two circular plates 411 move to the top end of the threaded cylinder 46 and the bottom end of the ring 412 respectively, thereby preventing the stud 41 from separating from the threaded cylinder 46.
[0031] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
