Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Please see Figure 1 This application provides a shearing device comprising a front support plate 1, a cutting mechanism 2, and a positioning mechanism 3. The front support plate 1 is used to hold the lead screw to be sheared. The cutting mechanism 2 is disposed on the upper surface of the front support plate 1. The cutting mechanism 2 includes a cutter 21, which is used to cut the lead screw. The positioning mechanism 3 includes a baffle plate 31, a scale 32, and a positioning plate 33. The baffle plate 31 is slidably connected to the upper surface of the front support plate 1, and the extending direction of the baffle plate 31 is perpendicular to the shearing direction of the cutter 21. The scale 32 is fixed above the baffle plate 31, and the starting end of the scale 32 is aligned with the connecting end of the baffle plate 31. The positioning plate 33 is connected to the connecting end of the baffle plate 31.

[0028] In this embodiment, the baffle plate 31, the scale 32, and the positioning plate 33 can slide together on the front support plate 1 to create a preset distance between the positioning plate 33 and the cutter 21. After the cutter 21 is raised, one end of the lead screw can pass under the cutter 21, and the end of the lead screw passing under the cutter 21 can abut against the positioning plate 33, so that the distance between the end of the lead screw abutting against the positioning plate 33 and the cutter 21 is equal to the preset distance. In this way, after the cutter 21 moves downward to cut the lead screw, a short lead screw of a predetermined size can be obtained.

[0029] Therefore, compared to manual shearing, the shearing device provided in this application can achieve precise shearing of the lead screw. Furthermore, the shearing device of this application is more labor-saving and has higher shearing efficiency.

[0030] The front support plate 1 can be a flat plate structure. The material of the front support plate 1 can be stainless steel. This way, the cutter 21 is less likely to damage the front support plate 1 during the shearing process of the lead screw. The middle area of ​​the front support plate 1 can be designated as a placement area, where the lead screw to be sheared can be placed for cutting.

[0031] The cutting mechanism 2 can be welded or pin-connected to the upper surface of the front support plate 1, and this embodiment does not specifically limit this. After the cutting mechanism 2 is disposed on the upper surface of the front support plate 1, the cutter 21 can be located above the aforementioned placement area to facilitate cutting the lead screw.

[0032] The baffle 31 can be configured as a long strip, and the baffle 31 can be slidably connected to both sides of the aforementioned placement area. The extension direction of the baffle 31 being perpendicular to the cutting direction of the cutter 21 means that the angle between the extension direction of the baffle 31 and the cutting direction of the cutter 21 is 90°.

[0033] The ruler 32 can be fixed to the baffle 31 by snap-fit ​​or adhesive, etc., and this embodiment does not impose any special limitation on this. The starting end of the ruler 32 refers to the end where the scale begins. The connecting end of the baffle 31 refers to the end that is connected to the positioning plate 33. Alignment between the starting end of the ruler 32 and the connecting end of the baffle 31 means that the end face of the starting end of the ruler 32 is coplanar with the end face of the connecting end of the baffle 31.

[0034] The positioning plate 33 can be configured as a thin plate structure. The positioning plate 33 can be welded to the connecting end of the baffle plate 31. After the positioning plate 33 is connected to the connecting end of the baffle plate 31, the starting end of the scale 32 can fit against the surface of the positioning plate 33, so that after sliding the baffle plate 31, the scale 32 and the positioning plate 33, a more accurate preset distance can be achieved between the positioning plate 33 and the cutter 21.

[0035] In some embodiments, please continue to see Figure 1 There are two guard plates 31, which are located on both sides of the cutter 21; the connecting ends of the two guard plates 31 are connected to the positioning plate 33.

[0036] In this embodiment, when two baffles 31 are provided, the two baffles 31 can slide together on the front support plate 1. Furthermore, based on the connection between the baffles 31 and the positioning plate 33, the two baffles 31 can mutually restrict each other through the positioning plate 33, preventing them from easily tilting during movement. With the baffles 31 not tilting, the positioning plate 33 will also not tilt, which helps ensure that the distance between each part of the positioning plate 33 and the cutter 21 is a preset distance. Thus, when cutting multiple lead screws simultaneously, the distance between the ends of the multiple lead screws that abut against the positioning plate 33 and the cutter 21 is equal to the preset distance, facilitating the cutting of multiple short lead screws of the same size in one operation.

[0037] In some embodiments, the upper surface of the front support plate 1 is provided with a groove, and the bottom of the baffle 31 is provided with a slider (not shown in the figure) adapted to the groove. Alternatively, the upper surface of the front support plate 1 is provided with a slider, and the bottom of the baffle 31 is provided with a groove (not shown in the figure) adapted to the slider. The baffle 31 is slidably connected to the front support plate 1 by the slider and the groove.

[0038] In this embodiment, during the sliding process of the baffle 31 on the front support plate 1, the groove wall of the slide and the outer wall of the slider can abut against each other and limit each other, which is conducive to the baffle 31 sliding along the predetermined trajectory without tilting, and makes it easier to ensure the preset distance between the positioning plate 33 and the cutter 21.

[0039] In the above embodiments, after the baffle 31, scale 32, and positioning plate 33 slide a predetermined distance on the front support plate 1, a large gap may be created between the positioning plate 33 and the cutter 21. Thus, when a longer truncated lead screw needs to be cut, the end of the lead screw passing under the cutter 21 may bend towards the gap under its own weight, causing the end of the lead screw to fail to abut against the positioning plate 33, making it difficult to obtain a truncated lead screw of the preset size.

[0040] Therefore, in some embodiments, please refer to... Figure 1 The shearing device also includes a rear support plate 4, which is connected to the side of the front support plate 1 near the positioning plate 33 and is flush with the upper surface of the front support plate 1. The rear support plate 4 is used to support the lead screw.

[0041] In this embodiment, the rear support plate 4 can support the end of the lead screw that passes through the cutter 21 from below, so as to prevent the end of the lead screw that passes through the cutter 21 from deflecting toward the hollow part, and ensure that the end of the lead screw that passes through the cutter 21 from below can abut against the positioning plate 33.

[0042] The structure of the rear support plate 4 can be the same as that of the front support plate 1. The rear support plate 4 and the front support plate 1 can be connected by a pin or by welding, and this application does not make specific limitations in this regard.

[0043] In the above embodiments, as the lead screw passes under the cutter 21, it may deflect, causing only a portion of the end of the lead screw passing under the cutter 21 to abut against the positioning plate 33, rather than the entire end. This results in the cut lead screw end face being beveled, leading to substandard cut lead screw lengths.

[0044] Therefore, in some embodiments, please refer to... Figure 1 The shearing device also includes a threading tube 5; the threading tube 5 is disposed on the upper surface of the front support plate 1 and is used to guide the lead screw.

[0045] In this embodiment, the lead screw can move from inside the threading tube 5 and pass under the cutter 21. During the process of the lead screw passing through, the inner wall of the threading tube 5 will restrict the lead screw so that the lead screw moves along a straight trajectory. This will help ensure that the end of the lead screw that passes under the cutter 21 abuts against the positioning plate 33, thereby making the end face of the cut lead screw flat and obtaining a qualified short lead screw.

[0046] The conduit 5 can be made of stainless steel and spot-welded to the aforementioned placement area. The conduit 5 can be a hollow cylindrical tube; alternatively, the cross-section of the conduit 5 can be C-shaped or U-shaped. This application embodiment does not specifically limit the specific structural form of the conduit 5. Multiple conduits 5 can be provided, and these multiple conduits 5 can be arranged along the relative directions of the two baffles 31.

[0047] It is worth noting that during the process of the cutter 21 cutting the lead screw, the conduit 5 needs to avoid the cutter 21 so that the cutter 21 can cut the lead screw. That is, the end of the conduit 5 extends to one side of the cutter 21 at most, rather than directly below the cutter 21.

[0048] In some embodiments, please combine Figure 1 and Figure 2 The cutting mechanism 2 also includes two guide posts 22, two blade holders 23, a connecting plate 24, and a handle 25; the two guide posts 22 are fixed to the upper surface of the front support plate 1; the two blade holders 23 are correspondingly sleeved between the two guide posts 22, and the cutter 21 is connected between the two blade holders 23; the connecting plate 24 is connected to the top of the two guide posts 22; one end of the handle 25 is rotatably connected to the connecting plate 24, and the middle part of the handle 25 is connected to the cutter 21.

[0049] The guide post 22 is configured as a smooth cylinder, and the two blade holders 23 are in close contact with the two guide posts 22 to avoid excessive friction during the up-and-down movement of the blade holders 23 with the cutter 21, and to prevent unnecessary resistance from being overcome when operating the handle 25.

[0050] In this embodiment, when the handle 25 rotates relative to the connecting plate 24, it can drive the cutter 21 to move up and down through the middle part. When the cutter 21 moves upward, it facilitates the lead screw to pass under the cutter 21. When the cutter 21 moves downward, it can cut the lead screw. Furthermore, during the movement of the cutter 21, the cutter 21 can drive the blade holder 23 to move along the peripheral wall of the guide post 22. In this way, the guide post 22 can guide the blade holder 23, and the blade holder 23 can restrict the cutter 21 to prevent the cutter 21 from swaying during movement.

[0051] In some embodiments, please continue to see Figure 2 The cutting mechanism 2 also includes a linkage assembly 26 connected to the middle part of the handle 25 and the cutter 21; the linkage assembly 26 includes a bolt 261, a connecting rod 262 and a connecting post 263; the bolt 261 is fixed to the cutter 21; the connecting post 263 is fixed to the middle part of the handle 25; one end of the connecting rod 262 is movably sleeved on the periphery of the bolt 261, and the other end of the connecting rod 262 is rotatably sleeved on the connecting post 263.

[0052] In this embodiment, when the handle 25 rotates relative to the connecting plate 24, the middle part of the handle 25 can drive the cutter 21 to move up and down through the connecting post 263, the connecting rod 262, and the bolt 261. During the up and down movement of the cutter 21, based on the movable connection between the connecting rod 262 and the connecting post 263, and the movable connection between the connecting rod 262 and the cutter 21, the angle between the connecting rod 262 and the cutter 21, as well as the angle between the connecting rod 262 and the handle 25, can change to avoid jamming and prevent the cutter 21 from moving up and down.

[0053] In some embodiments, please continue to see Figure 2 The connecting rod 262 includes a first section 2621, a second section 2622, and a positioning nut 2623; the first section 2621 is sleeved with the bolt 261, the second section 2622 is connected with the connecting post 263, the first section 2621 is sleeved outside the second section 2622, and the positioning nut 2623 is sleeved at the joint of the first section 2621 and the second section 2622.

[0054] In this embodiment, the first segment 2621 can move relative to the second segment 2622, thereby changing the length of the connecting rod 262. This allows the cutter 21 to move upwards at different heights based on the length of the connecting rod 262, facilitating the passage of lead screws of different diameters under the cutter 21. When the length of the connecting rod 262 is fixed at a certain dimension, the positioning nut 2623 can limit the first segment 2621 and the second segment 2622, ensuring that the dimension of the connecting rod 262 remains at that dimension.

[0055] It should also be noted that you can refer to [link / reference]. Figure 2 The distance between the handle part a of the handle 25 and the connecting post 263 is greater than the distance between the rotating part b of the handle 25 and the connecting post 263. In other words, the connecting post 263 acts as a fulcrum, and by using the lever principle, a small force can be applied to the handle part a of the handle 25 to complete the shearing work of the lead screw.

[0056] Furthermore, in actual operation, the time to complete one shearing operation is usually 1 to 2 seconds. That is to say, the shearing of the lead screw can be completed in a short time without any interruption. The shearing process is completed continuously in one go, thus ensuring a smooth shearing surface of the lead screw and improving the shearing quality.

[0057] In the aforementioned embodiments, when the lead screw is long, for example, greater than 1 meter, the end of the lead screw that does not abut against the positioning plate 33 may be affected by external forces and wobble, causing the entire lead screw to wobble, affecting the abutment between the lead screw and the positioning plate 33, or causing the lead screw to be scratched by the conduit 5.

[0058] Based on this, in some embodiments, please refer to Figure 1 and Figure 3 The shearing device also includes a limiting mechanism 6, which is located at the end of the wire tube 5 away from the positioning plate 33. The limiting mechanism 6 includes a support frame 61, a lower clamping plate 62, an upper clamping plate 63, and an electric push rod 64. The support frame 61 is fixed to the front support plate 1. The lower clamping plate 62 is connected to the lower part of the support frame 61. The electric push rod 64 is connected to the upper part of the support frame 61. The upper clamping plate 63 is connected to the actuating end of the electric push rod 64, and the upper clamping plate 63 and the lower clamping plate 62 are positioned opposite each other.

[0059] In this embodiment, under the action of the electric push rod 64, the lower clamping plate 62 and the upper clamping plate 63 can clamp the middle part of the lead screw or the end of the lead screw away from the positioning plate 33 to limit the lead screw. In this way, the lead screw as a whole will not wobble under the action of shear force, which helps to ensure the stability of the lead screw abutting against the positioning plate 33 and the quality of the lead screw.

[0060] Both the upper clamping plate 63 and the lower clamping plate 62 can be provided with clamping grooves on opposite sides, which are adapted to the size of the lead screw. The lead screw can be clamped by the groove wall without wobble.

[0061] In some embodiments, please continue to see Figure 3 The support frame 61 includes two ear plates 611, two smooth rods 612, and a top plate 613; both ear plates 611 are connected to the front support plate 1, and the lower clamping plate 62 is connected between the two ear plates 611; the bottom ends of the two smooth rods 612 are respectively connected to the two ear plates 611, the top ends of the two smooth rods 612 are connected to the top plate 613, and the electric push rod 64 is connected to the top plate 613.

[0062] In this embodiment, the two ear plates 611 can fix the lower clamping plate 62 to ensure that the position of the lower clamping plate 62 is constant. The smooth rod 612 and the top plate 613 can fix the top plate 613, the top plate 613 can fix the electric push rod 64, and the electric push rod 64 can fix the upper clamping plate 63 to ensure that the position of the upper clamping plate 63 is constant. In this way, the upper clamping plate 63 and the lower clamping plate 62 can accurately clamp the lead screw to ensure that the position of the lead screw is constant, thereby ensuring the stability of the contact between the lead screw and the positioning plate 33.

[0063] Furthermore, a lifting plate 65 can be fitted onto the guide rod 612, and the upper clamping plate 63 can be fixed to the lifting plate 65. In this way, during the movement of the upper clamping plate 63 driven by the electric push rod 64, the guide rod 612 can guide the lifting plate 65 so that the upper clamping plate 63 moves up and down in a straight line without tilting, which helps to ensure the stability of the upper clamping plate 63 and the lower clamping plate 62 in clamping the lead screw.

[0064] Please combine Figures 1 to 3 The working principle of the shearing device in this application is as follows:

[0065] First, slide the baffle 31, the scale 32 and the positioning plate 33 so that there is a predetermined distance between the positioning plate 33 and the cutter 21.

[0066] Next, operate the handle 25 to rotate it upward. During the upward rotation of the handle 25, the cutter 21 is moved upward through the connecting rod 262, so that a gap is created between the cutter 21 and the front support plate 1 to facilitate the passage of the lead screw.

[0067] Next, one end of the lead screw is passed from the end of the front support plate 1 where the limiting mechanism 6 is located to the end where the positioning plate 33 is located. When the lead screw reaches the limiting mechanism 6, the electric push rod 64 is controlled to push the lifting plate 65 to rise along the surface of the smooth rod 612. During the rise of the lifting plate 65, the upper clamping plate 63 moves upward, creating a distance between the upper clamping plate 63 and the lower clamping plate 62 to facilitate the passage of the lead screw. Subsequently, when the lead screw reaches the wire guide tube 5, one end of the lead screw enters the inside of the wire guide tube 5 and moves along the wire guide tube 5 towards the positioning plate 33 until the end face of the lead screw abuts against the positioning plate 33. Then, the electric push rod 64 is controlled to push the lifting plate 65 to descend along the surface of the smooth rod 612. During the descent of the lifting plate 65, the upper clamping plate 63 moves downward, so that the upper clamping plate 63 and the lower clamping plate 62 clamp the lead screw.

[0068] Finally, operate the handle 25 to rotate it downwards. During the downward rotation of the handle 25, the cutter 21 is driven to move downwards through the connecting rod 262. During the downward movement of the cutter 21, the lead screw is cut off to obtain a short lead screw of the preset size.

[0069] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
