Description

Technical Field

[0001] This invention relates to the field of scissor mechanism technology, specifically to a scissor with an integrated scissor clamp. Background Technology

[0002] Existing scissors are generally manual, requiring manual operation for cutting, which is inconvenient. To improve usability, patent CN116711543A discloses an end effector, which includes a fixed blade, a moving blade, a connecting rod, a cylinder push rod, and a clamping device. The cylinder push rod drives the connecting rod, thereby causing the fixed blade and the moving blade to close and cut the object. The fixed blade and the moving blade are also equipped with a clamping device at their bottom to hold the object being cut, thus preventing it from falling. However, with this structure, the clamping device and the moving blade move together. The two clamping parts of the clamping device are too close together, which may damage the object. At the same time, this structure cannot control whether the clamping device will necessarily contact the object first. When cutting some thin objects, the scissors may contact the object first, causing it to fall. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a scissor with an integrated scissor clamp, which can clamp an object before cutting it to prevent it from falling after cutting, and also prevent the object from being damaged due to excessive clamping.

[0004] The technical solution is as follows: a pair of integrated scissors and clippers, comprising: a mounting base, wherein a rotating shaft is provided on the mounting base;

[0005] A scissor mechanism, rotatably mounted on the rotating shaft, the scissor mechanism comprising a first shearing component and a second shearing component;

[0006] A drive cylinder, which drives the scissor mechanism to open and close via a linkage mechanism;

[0007] The feature is that it further includes a floating clamping mechanism, which includes a floating clamping member and a fixed clamping member; the floating clamping member is rotatably connected to the rotating shaft, and a torsion spring is connected between the floating clamping member and the first shearing member. The torsion spring is used to provide a force to make the floating clamping member rotate inward between itself and the fixed clamping member. When the floating clamping mechanism clamps an object, the driving cylinder can make the first shearing member overcome the elastic force of the torsion spring and rotate inward relative to the floating clamping member.

[0008] A limiting block is also provided on the outer side of the floating clamping member, the limiting block extending to the outer side of the first shearing member. The limiting block is used to prevent the floating clamping member from rotating inward relative to the first shearing member when it contacts the first shearing member, and the distance between the inner side of the floating clamping member and the inner side of the fixed clamping member is smaller than the distance between the inner side of the first shearing member and the inner side of the second shearing member; the limiting block is also used to allow the floating clamping member to rotate outward together with the first shearing member when the scissor mechanism is opened.

[0009] Furthermore, the first shearing member and the second shearing member each include a connecting rod end located at one end, a shearing end located at the other end, and a rotating shaft connecting part located in the middle. The connecting rod end is connected to the connecting rod mechanism, and the rotating shaft connecting part is connected to the rotating shaft.

[0010] Furthermore, the linkage mechanism includes a first linkage and a second linkage, one end of the first linkage and the second linkage are rotatably connected to the output end of the drive cylinder, and the other end of the first linkage and the second linkage are rotatably connected to the linkage connection end of the first shear member and the second shear member, respectively.

[0011] Furthermore, the fixing clamp is fixedly connected to the second shearing member.

[0012] Furthermore, the inner sides of the floating clamp and the fixed clamp are also provided with toothed clamping surfaces.

[0013] Furthermore, the integrated shearing and clamping scissors also include an external connecting seat and a mounting plate. The external connecting seat is used to connect the robotic arm, and the mounting plate is used to mount the mounting seat and the drive cylinder.

[0014] Furthermore, the mounting plate is also equipped with a camera on the side facing the scissor mechanism to identify the object that needs to be cut and clamped.

[0015] Beneficial effects: When using this device, the object is first held by the floating clamping mechanism, and then the scissor mechanism cuts the object. This avoids the situation where the object falls as soon as the scissor mechanism comes into contact with the object. At the same time, since the floating clamping mechanism relies on the torsion spring to connect with the first shearing component to create the floating effect, the object will not be damaged due to excessive clamping force when it is clamped.

[0017] Figure 2 This is a schematic diagram of the installation structure of the scissor mechanism;

[0018] Figure 3This is a schematic diagram of the installation structure of the floating clamping component. Detailed Implementation

[0019] like Figure 1 , Figure 2 The illustrated shears include: an external connecting seat 1 for connecting a robotic arm; a mounting seat 2 with a rotating shaft 2-1 on it; a mounting plate 3 for mounting the mounting seat 2 and a drive cylinder 5; a shear mechanism 4 rotatably mounted on the rotating shaft 2-1 and including a first shearing element 4-1 and a second shearing element 4-2; a drive cylinder 5 that drives the shear mechanism 4 to open and close via a linkage mechanism 7, which can also be replaced by an electric cylinder or other similar device; a camera 6 mounted on the mounting plate 3 for identifying objects that need to be sheared and clamped; and a floating clamping mechanism 8, including a floating clamping element 8-1 and a fixed clamping element 8-2, the inner sides of which may be provided with toothed clamping surfaces for more stable clamping of objects.

[0020] Among them, combined Figure 3 As shown, the floating clamping member 8-1 is rotatably connected to the rotating shaft 2-1. A torsion spring 8-3 is also connected between the floating clamping member 8-1 and the first shearing member 4-1 (the torsion spring 8-3 is connected to the floating clamping member 8-1 at point A and to the first shearing member 4-1 at point B). The torsion spring 8-3 is used to provide force to make the floating clamping member 8-1 rotate inward. The fixed clamping member 8-2 is fixedly connected to the second shearing member 4-2. When the floating clamping mechanism 8 clamps an object, the driving cylinder 5 can make the first shearing member 4-1 overcome the elastic force of the torsion spring 8-3 and rotate inward relative to the floating clamping member 8-1 through the connector 5-1, thereby shearing the object. A limiting block 8-4 is also provided on the outer side of the floating clamping member 8-1. The limiting block 8-4 extends to the outer side of the first shearing member 4-1. The limiting block 8-4 is used to prevent the floating clamping member 8-1 from rotating inward relative to the first shearing member 4-1 when it contacts the first shearing member 4-1. At this time, the distance between the inner side of the floating clamping member 8-1 and the inner side of the fixed clamping member 8-2 is less than the distance between the inner side of the first shearing member 4-1 and the inner side of the second shearing member 4-2, so that the object first contacts and is clamped by the floating clamping mechanism 8, and then is cut by the scissor mechanism 4. The limiting block 8-4 is also used to make the floating clamping member 8-1 rotate outward together with the first shearing member 4-1 when the scissor mechanism 4 is opened.

[0021] Specifically, the first shearing member 4-1 and the second shearing member 4-2 each include a connecting rod end at one end, a shearing end at the other end, and a rotating shaft connecting part in the middle. The connecting rod end is connected to the linkage mechanism 7, and the rotating shaft connecting part is connected to the rotating shaft 2-1. The linkage mechanism 7 includes a first connecting rod and a second connecting rod. One end of the first connecting rod and the second connecting rod are rotatably connected to the connecting head 5-1 of the drive cylinder, and the other ends of the first connecting rod and the second connecting rod are rotatably connected to the connecting rod ends of the first shearing member 41 and the second shearing member 4-2, respectively.

[0022] During installation, the device can be mounted on a robotic arm or telescopic arm via the external connector 1, making installation convenient. In use, the control cylinder 5 extends its connector 5-1. The connector 5-1, through the linkage mechanism 7, causes the first shearing piece 4-1 and the second shearing piece 4-2 to rotate around the pivot 2-1, thereby gradually closing the scissor mechanism 4. During this process, as the first shearing piece 4-1 rotates inward, the floating clamping piece 8-1 also rotates inward under the action of the torsion spring 8-3. At the same time, because the distance between the floating clamping piece 8-1 and the fixed clamping piece 8-2 is smaller, they can clamp the object first. After clamping the object, the first shearing piece 4-1 can rotate relative to the floating clamping piece 8-1, thereby causing the floating clamping mechanism 8 to produce a floating clamping effect, avoiding damage to the object. Finally, the first shearing piece 4-1 and the second shearing piece 4-2 come together to complete the shearing of the object. When the shearing is completed and the scissor mechanism 4 is opened, the first shearing piece 4-1 and the second shearing piece 4-2 move away from each other until the first shearing piece 4-1 contacts the limit block 8-4, causing the floating clamping piece 8-1 to rotate outward and release the object.

[0023] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
