[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5This utility model provides a precision cutting device for adapter springs: it includes a housing 10 and a cutting device 11 located directly above the center of the top of the housing 10. A platform 12 is rotatably connected to the center of the top of the housing 10 corresponding to the position of the cutting device 11. The top of the housing 10, outside the platform 12, has several sliding grooves arranged in a circular array. The extension direction of each sliding groove is towards the platform 12. A vertical limiting rod 20 is slidably connected within the sliding groove. The limiting rod 20 is away from the cutting device 11. One end of the cutting device 11 is located inside the housing 10. A limiting plate 21 is sleeved on the outer side of the end of the limiting rod 20 away from the cutting device 11. The ends of several limiting plates 21 that are far apart from each other are inclined away from the cutting device 11. The ends of several limiting plates 21 that are close to each other are fixedly connected to the same horizontally arranged fixing plate 23. An electric push rod 24 is fixedly connected at the bottom center of the fixing plate 23. The end of the electric push rod 24 that is away from the fixing plate 23 is fixed to the bottom inner wall of the housing 10.

[0026] It should be noted that: support columns are fixedly connected to the four corners of the top of the box 10, and the same top plate is fixedly connected to the end of the four support columns away from the box 10. A cross slide rail is provided on the side wall of the top plate near the box 10, and the cutting device 11 is fixedly connected to the slider of the cross slide rail.

[0027] The housing 10 has a hollow structure, and most of the components of the clamping mechanism are located inside the housing 10. The limiting plate 21 is set at an angle, that is, the end of the limiting plate 21 near the axis of the shelf 12 is higher than the end of the limiting plate 21 away from the axis of the shelf 12.

[0028] Please see Figures 1-5 The present invention provides a technical solution: a channel 1 extending vertically through the top center of the limiting plate 21 is provided, the length direction of the channel 1 is consistent with the length direction of the limiting plate 21, the end of the limiting rod 20 away from the cutting device 11 slides in the channel 1, and rollers 22 are rotatably connected to both sides of the bottom end of the limiting rod 20, the outer arc wall of the rollers 22 rolls against the side wall of the limiting plate 21 near the cutting device 11, and the two rollers 22 are respectively located on both sides of the channel 1.

[0029] It should be noted that: in one possible embodiment, the cross-section of the limiting plate 21 is a square ring, and the end of the limiting rod 20 away from the cutting device 11 slides inside the limiting plate 21, i.e., inside the channel. The roller 22 is used to reduce the friction between the limiting rod 20 and the limiting plate 21 and to provide support for the limiting rod 20.

[0030] Please see Figures 1-5The present invention provides a technical solution: a return spring 25 is fixedly connected to one end of the limiting rod 20 located in the slide groove, on the side wall away from the table 12. The axial direction of the return spring 25 is parallel to the length direction of the slide groove. The end of the return spring 25 away from the limiting rod 20 is fixedly connected to the inner side wall of the slide groove away from the table 12.

[0031] It should be noted that when the electric push rod 24 drives the fixed plate 23 to move vertically, the fixed plate 23 drives several limiting plates 21 to move vertically. When the limiting plate 21 rises, the inclined surface of the limiting plate 21 forces the roller 22 to move away from the platform 12. At this time, several limiting rods 20 move towards the side away from the platform 12, that is, disperse. When the limiting plate 21 falls, the obstruction effect of the inclined surface of the limiting plate 21 on the roller 22 weakens, and the limiting rods 20 will converge towards the platform 12 under the action of the return spring 25, that is, converge.

[0032] Please see Figures 1-5 The present invention provides a technical solution: the limiting rod 20 is fixedly connected to both sides of one end of the sliding groove, and a limiting groove is opened on the inner wall of the sliding groove corresponding to the position of the limiting slider. The limiting slider slides in the limiting groove, and flexible material is provided on the side wall of several limiting rods 20 that are close to each other.

[0033] It should be noted that the limiting slider is used to guide and limit the movement trajectory of the limiting rod 20, and also to provide auxiliary support for the limiting rod 20. It also ensures that the limiting rod 20 will not move in the vertical direction.

[0034] Please see Figures 1-5 This utility model provides a technical solution: a vertical rotating rod 30 is rotatably connected to the top center of the fixed disk 23. A limiting block is fixedly connected to one end of the rotating rod 30 away from the guide groove 31. Several guide grooves 31 are arranged in a ring array on the outer arc wall of the rotating rod 30 near the limiting block. The guide groove 31 includes a vertical part and an inclined part. The length direction of the vertical part is parallel to the axis of the rotating rod 30. The two ends of the inclined part are connected to the vertical part. The three parts are interconnected and smoothly transition to each other. The two vertical parts are not located on the same vertical line. A guide rod 32 slides in the guide groove 31.

[0035] It should be noted that the rotating rod 30 is coaxially arranged with the platform 12. In one possible embodiment, the limiting block is a regular polygonal structure, and multiple inclined parts can be provided in the guide groove 31, and the degree of inclination can be changed according to the specific application.

[0036] Please see Figures 1-5The present invention provides a technical solution: the guide rod 32 is horizontally arranged and the length direction of the guide rod 32 is parallel to the radial direction of the rotating rod 30. The ends of several guide rods 32 that are far apart from each other are fixedly connected to the same fixed cylinder 33. The fixed cylinder 33 is fixedly connected to the inner wall of the top of the box 10. The top of the fixed cylinder 33 is coaxially provided with a fixed block 34. The fixed block 34 passes through the box 10 and is fixedly connected to the shelf 12.

[0037] The fixed block 34 is provided with a slot at one end away from the shelf 12. The fixed block 34 is rotatably connected to the inner wall of the top of the box 10. The fixed block 34 is coaxially arranged with the rotating rod 30. The limiting block is adapted to the slot.

[0038] It should be noted that when the electric push rod 24 drives the fixed plate 23 to move, the fixed plate 23 will drive the rotating rod 30 to move synchronously. In the initial state, the guide rod 32 is located in a vertical section of the guide groove 31 near the fixed plate 23. When the rotating rod 30 moves, the guide rod 32 will slide relative to the guide groove 31 in the guide groove 31. When the inclined section of the guide groove 31 moves to the guide rod 32, the guide groove 31 will be forced to rotate under the restriction of the guide rod 32. At the same time, the limit block is located in the slot on the fixed block 34, thereby driving the table 12 to rotate synchronously.

[0039] Because the length of the tilting section is relatively small, it will only cause the shelf 12 to rotate slightly. The slight swing of the shelf 12 can be achieved by using multiple tilting sections in different positions and directions.

[0040] Working principle:

[0041] The workpiece to be cut is placed on the platform 12. Then, the electric push rod 24 drives the fixed plate 23 to move vertically. When the fixed plate 23 moves toward the platform 12, the inclined surface of the limiting plate 21 forces the roller 22 to move away from the platform 12. Several limiting rods 20 move toward the side away from the platform 12. When the limiting plate 21 descends, the obstruction effect of the inclined surface of the limiting plate 21 on the roller 22 weakens. The limiting rods 20 will converge toward the platform 12 under the action of the return spring 25 to clamp the workpiece.

[0042] When the fixed plate 23 descends, the rotating rod 30 is forced to rotate under the action of the guide groove 31 and the guide rod 32, which in turn drives the platform 12 to rotate, causing the workpiece on the platform 12 to swing, thus preventing the limiting rod 20 from clamping the corner of the workpiece and causing insufficient clamping force.
