Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] See attached document Figure 1 -Appendix Figure 5 The present invention provides a fixed-distance moving mechanism for thin sheet parts, including a frame 1, two linear guide rails 2 fixedly installed inside the frame 1, a servo motor 3 installed on one side of the frame 1, a ball screw 4 inserted inside the frame 1, a clamping assembly 5 sleeved on the outside of the ball screw 4, the clamping assembly 5 including a threaded seat 51, a connecting frame 52 fixedly installed on the top of the threaded seat 51, two guide rail sliders 53 fixedly installed at the bottom of the connecting frame 52, a motor mounting hole 54 opened inside the threaded seat 51, two obstacle avoidance grooves 55 opened on the top of the threaded seat 51, a through groove 56 opened on the top of the threaded seat 51, a thin sheet placement unit 57 inside the threaded seat 51, and thin sheet limiting units 58 on both sides of the thin sheet placement unit 57;

[0027] In this embodiment, in order to fix the sheet part body 6 and prevent its deformation, and to ensure that the sheet part body 6 does not shift or shake during the fixed-distance movement, the sheet pressure plates 584 on both sides of the sheet limiting unit 58 are moved according to the actual size of the sheet part body 6, thereby precisely adjusting the distance between the two sheet pressure plates 584 to ensure that they can effectively press the sheet part body 6. When it is necessary to clamp the sheet part body 6, the sheet part body 6 is placed stably on the top of the sheet placement stage 574. Then, the sheet placement stage 574 in the sheet placement unit 57 moves upward so that the sheet part body 6 contacts the sheet pressure plate 584 and is clamped. This vertical clamping method effectively avoids the deformation of the sheet part and ensures the stability of the part during subsequent movement.

[0028] To achieve the purpose of fixed-distance conveying of thin sheet parts, this device adopts the following technical solution: servo motor 3 is fixedly connected to frame 1; the output end of servo motor 3 is fixedly connected to one end of ball screw 4; ball screw 4 passes through both side walls of frame 1 and is connected to both side walls of frame 1 via bearings; ball screw 4 passes through threaded seat 51 and is connected to threaded seat 51 via threads; guide rail slider 53 is sleeved on the top of linear guide rail 2 and is slidably connected to the top of linear guide rail 2; the top of thin sheet placement stage 574 passes through through groove 56 and is slidably connected to through groove 56; thin sheet... The top of the placement table 574 is provided with a thin sheet part body 6. The thin sheet part body 6 is clamped and fixed by the cooperation of the thin sheet placement unit 57 and the thin sheet limiting unit 58 to ensure that the thin sheet part body 6 will not be displaced or shaken during the fixed distance movement. The servo motor 3 drives the ball screw 4 to rotate. When the ball screw 4 rotates, it drives the threaded seat 51 to move linearly along the ball screw 4 at a fixed distance. The guide rail slider 53 and the linear guide rail 2 are used to provide precise linear motion guidance to ensure the stability and accuracy of the thin sheet part during the movement and achieve the purpose of fixed distance conveying.

[0029] To achieve the purpose of clamping and fixing thin sheet parts 6 of different sizes, this device adopts the following technical solution: The thin sheet placement unit 57 includes a second servo motor 571, which is fixedly installed inside the motor mounting hole 54. A threaded shaft 572 is fixedly connected to the output end of the second servo motor 571. A threaded sleeve 573 is sleeved on the outside of the threaded shaft 572. The threaded shaft 572 and the threaded sleeve 573 are connected by threads. A thin sheet placement stage 574 is fixedly installed on the top of the threaded sleeve 573. The thin sheet restraint unit 58 includes an electric push rod 581, which is fixedly connected to the connecting frame 52. A push rod output shaft 582 is fixedly connected to the output end of the electric push rod 581. The push rod output shaft 582 passes through one side wall of the connecting frame 52 and is slidably connected to one side wall of the connecting frame 52. A connecting bracket 583 is fixedly connected to the other end of shaft 582. A thin sheet pressure plate 584 is fixedly provided at the bottom of one end of the connecting bracket 583. The bottom of the connecting bracket 583 is located inside the connecting frame 52 and is slidably connected to the connecting frame 52. The connecting bracket 583 passes through the obstacle avoidance groove 55 and is slidably connected to the obstacle avoidance groove 55. In order to ensure that the thin sheet part body 6 will not be displaced or shaken during the fixed distance movement, the distance between the two thin sheet pressure plates 584 is first adjusted by starting the electric push rod 581 according to the actual size of the thin sheet part body 6. When the electric push rod 581 is working, its push rod output shaft 582 drives the connecting bracket 583 to move. The connecting bracket 583 then drives the thin sheet pressure plate 584 to move, thereby accurately adjusting the distance between the two thin sheet pressure plates 584 to ensure that they can effectively press the thin sheet part body 6.

[0030] The usage process of this utility model is as follows: When using this utility model, connect an external power source to provide power support for the entire mechanism. Set the rotation angle and speed of the servo motor through the control system to determine the moving distance and speed of the sheet metal body 6. To ensure that the sheet metal body 6 does not shift or shake during the fixed-distance movement, firstly, based on the actual size of the sheet metal body 6, adjust the distance between the two sheet metal pressure plates 584 by activating the electric push rod 581. When the electric push rod 581 is working, its push rod output shaft 582 drives the connecting bracket 583 to move, which in turn drives the sheet metal pressure plate 584 to move, thereby precisely adjusting the distance between the two sheet metal pressure plates 584 to ensure they can effectively press the sheet metal body 6. When it is necessary to clamp the sheet metal body 6, place it stably on top of the sheet metal placement table 574, then start the servo motor 571 to rotate clockwise. When servo motor 571 rotates, the threaded shaft 572 and threaded sleeve 573 drive the threaded sleeve 573 upward, which in turn drives the sheet placement platform 574 upward, thereby bringing the sheet part body 6 into contact with the sheet pressure plate 584 and clamping it. This vertical clamping method effectively avoids deformation of the sheet part and ensures the stability of the part during subsequent movement. After the sheet part body 6 is fixed, when a fixed-distance movement is required, servo motor 3 is started. Servo motor 3 drives the ball screw 4 to rotate. The rotation of the ball screw 4 is connected to the threaded seat 51, which in turn drives the entire fixture assembly 5 to move. During the movement of the fixture assembly 5, the guide rail slider 53 and the linear guide rail 2 are closely matched to ensure that the fixture assembly 5 can only make precise linear movements along the linear guide rail 2, thereby achieving high-precision fixed-distance movement of the sheet part body 6 and meeting the needs of different processing technologies for part movement.
