Description

Technical Field

[0001] This utility model relates to the field of gripper technology, specifically a toothed gripper. Background Technology

[0002] A staggered-tooth gripper is a common type of robotic gripper, mainly used for grasping and fixing workpieces.

[0003] A gripper with authorization announcement number CN220313376U includes a connecting seat, a rotating shaft, a drive bracket, and a manipulator. One end of the rotating shaft is rotatably mounted on the connecting seat, and the other end of the rotating shaft is fixedly connected to the drive bracket. The drive bracket includes a first limiting post and a second limiting post. The manipulator includes a first rotating segment and a second rotating segment. The first rotating segment is provided with a first limiting hole, and the second rotating segment is provided with a second limiting hole. When the manipulator grips an object, the first limiting post slides into the first limiting hole, and the second limiting post slides into the second limiting hole. At this time, the first limiting hole prevents the first limiting post from slipping out, and the second limiting hole prevents the second limiting post from slipping out. This gripper has a simple structure, maintains a constant gripping force when gripping objects, and has a good gripping effect. Existing grippers use a single tooth for gripping, which has limited gripping force and restricts the rotation angle of the gripper, making it difficult to adapt to the range of gripping large workpieces.

[0004] To address the aforementioned problems, a staggered-tooth gripper is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a staggered tooth gripper, which solves the problem that existing grippers in the background art use a single tooth for gripping, resulting in limited gripping force and restricted rotation angle, making it difficult to adapt to the wide range of workpiece clamping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a toothed gripper, comprising a guide frame, wherein an adjustable gripper driving mechanism is provided inside the guide frame, and an adjustable gripping distance adjustment mechanism is connected to one side of the gripper driving mechanism. The guide frame includes a fixed block, and the gripper driving mechanism includes a driving cylinder connected to the upper end of the fixed block, a lifting adjustment block movably engaged with the output end of the driving cylinder, a connecting block rotatably connected to one end of the lifting adjustment block, and a gripper component rotatably connected to one end of the connecting block. The gripper component is provided in two sets, and the two sets of gripper components are provided with interlaced claws. The gripping distance adjustment mechanism includes a rack assembly connected to one side of the gripper driving mechanism, and the rack assembly is connected to the gripper driving mechanism.

[0007] Preferably, the fixed block has an internal groove for limiting the lifting movement of the lifting adjustment block and a groove for limiting the horizontal displacement of the rack assembly.

[0008] Preferably, the gripper drive mechanism further includes a first rotating frame rotatably connected to the middle of the connecting block and one end of the rack assembly, and a second rotating frame rotatably connected to one side of the connecting block and one end of the rack assembly.

[0009] Preferably, the output end of the drive cylinder is connected to a circular block.

[0010] Preferably, the lifting adjustment block includes a merging block that is movably engaged with one side of the circular block, a straight plate is connected to one side of the merging block, and a column groove is formed on one side of the merging block.

[0011] Preferably, the upper, middle and lower ends of the connecting block are rotatably connected to a lifting adjustment block, a first rotating frame and a second rotating frame, and one end of the first rotating frame and the second rotating frame is rotatably connected to a rack assembly.

[0012] Preferably, the gripping distance adjustment mechanism further includes a motor component fixedly mounted on one side of the fixed block, the output end of the motor component being connected to a gear, and the gear meshing with two sets of rack assemblies.

[0013] Preferably, the rack assembly includes a rack frame meshing with one side of the rack assembly, an L-shaped frame fixedly disposed on one side of the rack frame, and the rack frame slidably disposed within a fixed block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides a staggered-tooth gripper, which, through the combination of a guide frame and a gripper drive mechanism, uses a fixing block for fixing and limiting, and a drive cylinder to drive the lifting adjustment block to rise and fall, thereby driving the connecting block to rotate. This, in conjunction with the gripper components, allows for adjustment of the clamping angle. The staggered arrangement of the staggered claws makes the two sets of gripper components more stable, reducing object displacement or rotation caused by single-point clamping. At the same time, when the staggered claws are staggered, they can apply pressure evenly at multiple points, enhancing the clamping force without damaging the object. This solves the problem that existing grippers use a single tooth for gripping, resulting in limited clamping force and restricted rotation angle of the gripper.

[0016] 2. The present invention provides a toothed gripper, which, through the setting of the gripping distance adjustment mechanism, allows the rack assembly to be horizontally moved, thereby driving the gripper drive mechanism to move horizontally in opposite directions, adjusting the overall gripping distance, enhancing the adaptability of the fixture, and solving the problem that the rotation angle of the existing grippers is limited and it is difficult to adapt to the range of gripping large workpieces.

[0023] 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.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1This utility model discloses a toothed gripper, including a guide frame 1. Inside the guide frame 1, there is a gripper drive mechanism 2 with an adjustable gripping angle. One side of the gripper drive mechanism 2 is connected to a gripping distance adjustment mechanism 3 with an adjustable gripping distance. The guide frame 1 includes a fixed block 11. The gripper drive mechanism 2 includes a drive cylinder 21 connected to the upper end of the fixed block 11 and a lifting adjustment block 22 movably engaged with the output end of the drive cylinder 21. One end of the lifting adjustment block 22 is rotatably connected to a connecting block 23, and one end of the connecting block 23 is rotatably connected to a gripper component 26. The gripper component 26 is provided with two sets, and the two sets of gripper components 26 are provided with interlaced claws 261. The gripping distance adjustment mechanism 3 includes a rack assembly 33 connected to one side of the gripper drive mechanism 2. The rack assembly 33 is connected to the gripper drive mechanism 2.

[0026] Specifically, the fixing block 11 serves to fix and limit the position, and the driving cylinder 21 can drive the lifting adjustment block 22 to rise and fall, thereby driving the connecting block 23 to rotate. This, in conjunction with the gripper 26, allows for adjustment of the clamping angle. The staggered arrangement of the interlocking claws 261 makes the two sets of gripper 26 more stable, reducing object displacement or rotation caused by single-point clamping. At the same time, when the interlocking claws 261 are interlocked, they can apply pressure evenly at multiple points, enhancing the clamping force without damaging the object. The rack assembly 33 in the gripping distance adjustment mechanism 3 can be horizontally moved, thereby driving the gripper drive mechanism 2 to move horizontally towards each other, adjusting the overall clamping distance and enhancing the adaptability of the fixture.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Combination Figures 2-5 The fixed block 11 has a lifting movable slot 12 for limiting the lifting adjustment block 22 and a horizontal displacement slot 13 for limiting the rack assembly 33. The lifting movable slot 12 has a lifting adjustment block 22 that can be raised and lowered, and the horizontal displacement slot 13 has a rack assembly 33 that can be horizontally displaced.

[0030] The gripper drive mechanism 2 also includes a first rotating frame 24 rotatably connected to the middle of the connecting block 23 and one end of the rack assembly 33, and a second rotating frame 25 rotatably connected to one side of the connecting block 23 and one end of the rack assembly 33. The first rotating frame 24, the second rotating frame 25 and the connecting block 23 cooperate to adjust the angle of the gripper 26.

[0031] The output end of the drive cylinder 21 is connected to a round block 211, which is engaged with the lifting adjustment block 22 to achieve the lifting adjustment of the lifting adjustment block 22.

[0032] The lifting adjustment block 22 includes a merging block 221 that is movably engaged with one side of the round block 211. A straight plate 222 is connected to one side of the merging block 221. A column groove 2211 is provided on one side of the merging block 221. The round block 211 is movably engaged in the column groove 2211. The two merging blocks 221 are located on both sides of the round block 211, which facilitates the round block 211 to control the lifting adjustment block 22. The horizontal setting of the straight plate 222 facilitates the horizontal movement of the lifting adjustment block 22 under the control of the gripping distance adjustment mechanism 3.

[0033] The upper, middle and lower ends of the connecting block 23 are rotatably connected to the lifting adjustment block 22, the first rotating frame 24 and the second rotating frame 25 respectively. One end of the first rotating frame 24 and the second rotating frame 25 is rotatably connected to the rack assembly 33. The connection of the connecting block 23 enables the gripper distance adjustment mechanism 3 and the gripper drive mechanism 2 to adjust the distance and angle synchronously.

[0034] Example 2:

[0035] Combination Figure 3 and Figure 5 The gripping distance adjustment mechanism 3 also includes a motor component 31 fixedly installed on one side of the fixed block 11. The output end of the motor component 31 is connected to a gear 32. The gear 32 meshes with two sets of rack assemblies 33. The motor component 31 drives the gear 32 to rotate, thereby causing the rack assemblies 33 to move towards each other.

[0036] The rack assembly 33 includes a rack frame 331 meshing with one side of the rack assembly 33. An L-shaped frame 332 is fixedly provided on one side of the rack frame 331. The rack frame 331 is slidably disposed in the fixed block 11. The rack frame 331 cooperates with the gear 32 to achieve horizontal drive. The L-shaped frame 332 is used to rotatably connect the first rotating frame 24 and the second rotating frame 25.
