[0018] Example 1
[0019] like Figures 1-3 As shown, the lead screw processing positioning and adjustment mechanism proposed in this embodiment includes a thread rolling machine 1, an adjustment plate assembly, and a positioning mechanism. One adjustment plate assembly is provided on each side of the thread rolling machine 1, allowing the processed lead screw to be clamped by the adjustment plate assembly, thereby preventing the lead screw from bending due to excessive length. The adjustment plate assembly includes multiple interlocking connecting plates 2 and intermediate plates 3, a moving component 5 provided at the bottom of each of the multiple connecting plates 2 and intermediate plates 3, a top slide rail 41 provided at the top of each of the multiple connecting plates 2, a slide rail 42 provided on each of the multiple intermediate plates 3, and a side slide rail 43 provided on both sides of each of the multiple slide rails 42. The side slide rails 43 are slidably connected to the top slide rails 41. Multiple positioning mechanisms are slidably provided on both adjustment plate assemblies.
[0020] In this embodiment, the user pulls the connecting plate 2 at one end according to the length of the optical axis. The connecting plate 2 is stably moved to the desired position by the moving component 5. At the same time, the top slide rail 41 pulls multiple sets of side slide rails 43, slide rail 42, side slide rail 43 and top slide rail 41 in sequence, thereby expanding the length of the adjustment plate assembly. The positioning mechanism will adjust the position of the optical axis by adjusting the position with the side slide rail 43, top slide rail 41 and slide rail 42, thereby improving the versatility of the device.
[0021] Example 2
[0022] like Figure 1 and Figure 3 As shown, the lead screw machining positioning and adjustment mechanism proposed in this embodiment, compared with the first embodiment, includes a movable seat assembly 6 slidably disposed on the adjustment plate assembly, and an adjustment assembly 7, a base 8, a bearing, a clamping assembly 10 and a mounting cover 9 arranged sequentially from bottom to top on the movable seat assembly 6; the inner circumferential surface of the bearing is connected to the clamping assembly 10, and the outer circumferential surface of the bearing is connected to the base 8 and the mounting cover 9.
[0023] In this embodiment, the user places the bearing on the clamping assembly 10 between the base 8 and the mounting cover 9 for fixation. During the optical axis processing, the optical axis will rotate and move in the direction of the thread rolling machine 1. The bearing and clamping assembly reduce the wear caused by the rotation of the optical axis and its movement in the direction of the thread rolling machine 1, thereby improving the processing quality of the lead screw.
[0024] Example 3
[0025] like Figures 1-3 As shown, the lead screw machining positioning adjustment mechanism proposed in this embodiment, compared with the first embodiment, includes a movable seat assembly 6 comprising a movable seat 61, multiple rollers 62 uniformly rotatably arranged at the bottom of the movable seat 61, and multiple balls 63 rolling on the movable seat 61; the multiple rollers 62 roll in contact with the top slide rail 41 and the top of the slide rail 42, and the multiple balls 63 roll in contact with the multiple slide rails 42 and the side slide rails 43. When the user adjusts the position of the movable seat 61, the rollers 62 on the movable seat 61 slide in contact with the top of the slide rails 42 and the top of the top slide rail 41, and the balls 63 slide in contact with the slide rails 42 and the side slide rails 43. The movable seat assembly 6 will at least contact the top slide rail 41, the slide rail 42, and the side slide rail 43, thereby allowing the movable seat assembly 6 to slide on adjustment plate assemblies of different lengths.
[0026] The adjustment assembly 7 includes two lifting frames 71 arranged opposite each other on the movable seat 61, a lifting rod 72 slidably arranged on the lifting frame 71, a plurality of lifting rollers 73 rotatably arranged on the lifting rod 72, a drive assembly 74 rotatably arranged on the lifting rod 72, a receiving frame 75 slidably arranged on the two lifting frames 71, and a nut 76 threadedly connected to the receiving frame 75. The lifting frame 71 has a rack portion. The drive assembly 74 includes a connecting shaft rotatably arranged on the lifting rod 72, and a handwheel and a gear coaxially arranged on the connecting shaft. The gear meshes with the rack portion.
[0027] In this embodiment, when the user rotates the handwheel, the gear is driven through the connecting shaft, which in turn drives the lifting rod 72 to rise through the rack. At the same time, multiple lifting rollers 73 reduce the friction of the lifting rod 72 and improve the smoothness of its movement. Additionally, the lifting rod 72 has a scale to ensure that the height of the multiple adjustment components 7 remains consistent.
[0028] Example 4
[0029] like Figure 1 and Figure 2As shown, the lead screw machining positioning adjustment mechanism proposed in this embodiment, compared with the first embodiment, includes a clamping assembly 10 comprising a cylinder 101 mounted on a bearing, multiple clamping frames 102 slidably mounted on the cylinder 101 along a ring, a spring 103 disposed between each of the multiple clamping frames 102 and the cylinder 101, and a clamping roller 104 disposed on each of the multiple clamping frames 102.
[0030] In this embodiment, when the user pulls one of the clamping frames 102 to leave a certain space for the optical axis to move between multiple clamping rollers 104, thereby multiple springs 103 drive multiple clamping frames 102 to move toward the optical axis, so as to avoid wear between the optical axis and the clamping assembly 10 during the optical axis transportation process.
[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
