Description

Technical Field

[0001] The present invention relates to the technical field of processing of automotive parts, and particularly to a grasping mechanism for a triangular bright strip buckle. Background Art

[0002] An automotive triangular bright strip buckle is an important component of an automotive frame body, and it needs to be cut during the processing; after cutting, it needs to be grasped and transported to other places for the processing of the next process.

[0003] However, in the prior art, the grasping process of the triangular bright strip buckle has the following defects: First, since the triangular bright strip buckle has no dedicated fixing part, it is relatively difficult to grasp it, and the triangular bright strip buckle is likely to fall from the gripper after being grasped; Second, during the grasping process, the force application intensity of the gripper is often increased to prevent the triangular bright strip buckle from falling, so it is easy to occur the phenomenon that the triangular bright strip buckle is deformed due to excessive grasping force. Summary of the Invention

[0004] Aiming at the above deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a grasping mechanism for a triangular bright strip buckle to solve the problems such as difficult clamping of the triangular bright strip buckle in the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problem is a grasping mechanism for a triangular bright strip buckle, and inwardly bent flanges are respectively arranged on both sides of the triangular bright strip buckle, including:

[0006] A driving component, including a fixed claw and a movable claw, and the movable claw is movably connected to the fixed claw;

[0007] A grasping component, including a first connecting portion and a second connecting portion, the first connecting portion is connected to the fixed claw, and the second connecting portion is connected to the movable claw; the grasping component has a first state and a second state: when the grasping component is in the first state, the width of the grasping component is greater than the distance between the two flanges; when the grasping component is in the second state, the width of the grasping component is less than the distance between the two flanges;

[0008] The movable claw moves relative to the fixed claw to enable the grasping component to be arbitrarily switched between the first state and the second state.

[0009] Further, the grasping component further includes: a first connecting piece, which is connected to the end of the first connecting portion away from the second connecting portion, and the first connecting piece is used for abutting against one of the flanges; a second connecting piece, which is connected to the end of the second connecting portion away from the first connecting portion, and the second connecting piece is used for abutting against the other flange.

[0010] Furthermore, the first connecting portion is arranged in a U shape and includes a bottom surface and two side surfaces. The two side surfaces are oppositely arranged at both ends of the bottom surface, and a first clamping groove for clamping the fixed clamping claw is formed between the two side surfaces.

[0011] Furthermore, the second connecting portion is arranged in a V shape and includes a first clamping piece and a second clamping piece which are fixedly connected. A second clamping groove for clamping the movable clamping claw is formed between the first clamping piece and the second clamping piece.

[0012] Furthermore, the movable clamping claw is slidably connected to the fixed clamping claw; an elastic portion is provided between the first connecting portion and the second connecting portion; the movable clamping claw slides relative to the fixed clamping claw to compress or release the elastic portion.

[0013] Furthermore, the elastic portion is arranged in a U shape and includes a top plate, a first side plate and a second side plate. One end of the first side plate is connected to the top plate, the other end of the first side plate is connected to the first connecting portion, one end of the second side plate is connected to the end of the top plate far from the first side plate, and the other end of the second side plate is connected to the second connecting portion;

[0014] The movable clamping claw slides relative to the fixed clamping claw to change the distance between the two top plates.

[0015] Furthermore, notches are formed in the top plate, the first side plate and the second side plate, and the three notches are connected to form a through groove;

[0016] It further includes a transition plate. One end of the transition plate is connected to the first connecting portion, the other end of the transition plate is connected to the first side plate, and the transition plate is connected to the through groove.

[0017] Furthermore, the driving assembly includes a fixed frame, the fixed clamping claw is fixedly connected to the fixed frame; a driving cylinder, which is rotatably connected to the fixed frame; a rotating block, which is fixedly connected to the piston rod of the driving cylinder. The rotating block has a first hinged portion and a second hinged portion. The first hinged portion is hinged to the movable clamping claw, and the second hinged portion is hinged to the fixed frame;

[0018] The piston rod of the driving cylinder extends and retracts to drive the movable clamping claw to move in a direction towards or away from the fixed clamping claw.

[0019] Furthermore, the movable clamping claw includes a sliding portion and a clamping portion fixedly perpendicular to the sliding portion. The sliding portion is slidably connected to the fixed clamping claw, and the clamping portion is clamped to the second connecting portion;

[0020] It further includes: a first hinge rod, one end of the first hinge rod is hinged to the first hinge portion, and the other end of the first hinge rod is hinged to the sliding portion; a second hinge rod, one end of the second hinge rod is hinged to the second hinge portion, and the other end of the second hinge rod is hinged to the fixing bracket.

[0021] Further, a limit block is fixed on the driving cylinder, and the piston rod of the driving cylinder expands and contracts to make the rotating block abut against or separate from the limit block. When the rotating block abuts against the limit block, the movement of the movable claw along the direction towards the fixed claw can be restricted.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] (1) The grasping assembly first switches to the second state, passes through between the two flanges, and then switches it to the first state, making the grasping assembly abut against the two flanges, connecting the grasping assembly with the triangular bright strip buckle, and finally realizing the grasping of the triangular bright strip buckle by the grasping assembly. In this process, to realize the grasping of the triangular bright strip buckle by the grasping assembly, it only needs to switch the grasping assembly from the second state to the first state. The steps are simple, the operation is convenient and the efficiency is high.

[0024] (2) By utilizing the width change of the grasping assembly between the first state and the second state, and cleverly using the flanges on both sides of the triangular bright strip buckle, the design is ingenious. When the grasping assembly abuts against the two flanges, the triangular bright strip buckle cannot fall off from the grasping assembly; at the same time, the grasping assembly abuts against the connection part of the flange and the body, and the strength at this part is higher than that of other parts of the triangular bright strip buckle and is not easy to deform. On the premise of ensuring that the triangular bright strip buckle does not fall off, the grasping assembly can also ensure that the triangular bright strip buckle will not deform during the grasping process, solving the problem that the triangular bright strip buckle is deformed due to increasing the grasping force to prevent the triangular bright strip buckle from falling off.

[0025] (3) The inclined plate is provided to prevent the fixed claw from sliding along the length direction of the bottom surface relative to the first connecting portion; it can also make the process of the fixed claw entering the first card slot smoother, and increase the connection strength between the grasping assembly and the fixed claw after the fixed claw enters the first card slot, and the grasping assembly is not easy to fall off from the fixed claw.

[0026] (4) A through groove is opened at the central position of the elastic member, and this through groove can make the elastic part more easily deform, avoiding the deformation of other parts of the grasping component.

[0027] (5) A rotating block, a first hinge rod, and a second hinge rod are provided to convert the telescopic direction of the piston rod into the sliding direction of the movable claw that is approximately perpendicular. Moreover, the rotation of the first hinge rod, the second hinge rod, and the rotating block consumes part of the telescopic stroke of the piston rod. Therefore, the sliding stroke of the movable claw must be less than the telescopic stroke of the piston rod (i.e., a deceleration effect is achieved), and it is only necessary to roughly control the telescopic stroke of the piston rod within a certain range. More importantly, the angle between the first hinge rod and the sliding direction of the movable claw changes continuously with the telescopic movement of the piston rod. Specifically, when the piston rod extends uniformly, the angle between the first hinge rod and the sliding direction of the movable claw gradually increases (gradually approaches parallel), that is, the sliding speed of the movable claw gradually increases, avoiding damage to the grasping assembly due to too fast a speed at the beginning of compressing the elastic part. When the piston rod shortens uniformly, the angle between the first hinge rod and the sliding direction of the movable claw gradually decreases (gradually approaches perpendicular), that is, the sliding speed of the movable claw gradually decreases, so as to quickly release the elastic part to avoid damage to the elastic part due to too long a compression time.

[0038] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0039] Please refer to Figures 1-6 , the present invention discloses a gripping mechanism for a triangular bright strip buckle. The two sides of the triangular bright strip buckle 300 are respectively provided with a flange 310 bent inward, including:

[0040] A driving assembly 100, including a fixed claw 110 and a movable claw 120, and the movable claw 120 is movably connected to the fixed claw 110;

[0041] A gripping assembly 200, including a first connecting part 210 and a second connecting part 220. The first connecting part 210 is connected to the fixed claw 110, and the second connecting part 220 is connected to the movable claw 120; the gripping assembly 200 has a first state and a second state: when the gripping assembly 200 is in the first state, the width of the gripping assembly 200 is greater than the distance between the two flanges 310; when the gripping assembly 200 is in the second state, the width of the gripping assembly 200 is less than the distance between the two flanges 310;

[0042] The movable claw 120 moves relative to the fixed claw 110 to enable the gripping assembly 200 to be arbitrarily switched between the first state and the second state.

[0043] It should be noted that the triangular bright strip buckle 300 includes a body 320 and flanges 310 bent inward from both sides of the body 320. The inward bending can be understood as: its bending direction is from the side of the body 320 towards the center direction; it can also be interpreted as: the included angle between the flange 310 and the body 320 is less than 90°, so that the two ends of the gripping assembly 200 in the first state abut against the flange 310 (optimally, the connection between the flange 310 and the body 320), and the gripping assembly 200 cannot be detached from the flange 310.

[0044] Specifically, the width of the grasping component 200 in the second state is smaller than the distance between the two flanges 310. That is, in the second state, the grasping component 200 can pass through between the two flanges 310; the width of the grasping component 200 in the first state is greater than the distance between the two flanges 310. That is, in the first state, the grasping component 200 will abut against the two flanges 310 and cannot pass through between the two flanges 310. That is, the grasping component 200 can be first switched to the second state to enable the grasping component 200 to pass through between the two flanges 310, and then switched to the first state to make the grasping component 200 abut against the two flanges 310, so as to connect the grasping component 200 with the triangular bright bar buckle 300, and finally realize the grasping of the triangular bright bar buckle 300 by the grasping component 200.

[0045] In this process, to realize the grasping of the triangular bright bar buckle 300 by the grasping component 200, it only needs to switch the grasping component 200 from the second state to the first state. The steps are simple, the operation is convenient and the efficiency is high.

[0046] By utilizing the width change of the grasping component 200 between the first state and the second state, and cleverly using the flanges 310 on both sides of the triangular bright bar buckle 300, the design is ingenious. When the grasping component 200 abuts against the two flanges 310, the triangular bright bar buckle 300 cannot fall off from the grasping component 200; at the same time, the grasping component 200 abuts against the connection part of the flange 310 and the body 320, and the strength at this place is higher than that of other parts of the triangular bright bar buckle 300 and is not easy to deform. To sum up, the grasping component 200 in this embodiment can ensure that the triangular bright bar buckle 300 will not deform during the grasping process on the premise of ensuring that the triangular bright bar buckle 300 does not fall off, and solves the problem that the triangular bright bar buckle 300 is deformed due to increasing the grasping force to prevent the triangular bright bar buckle 300 from falling off.

[0047] Further, the grasping component 200 further includes: a first connecting piece 230, which is connected to one end of the first connecting portion 210 away from the second connecting portion 220, and the first connecting piece 230 is used to abut against one of the flanges 310; a second connecting piece 240, which is connected to one end of the second connecting portion 220 away from the first connecting portion 210, and the second connecting piece 240 is used to abut against the other flange 310.

[0048] Specifically, the first connecting piece 230 and the second connecting piece 240 are at both ends of the grasping component 200. Under the first state and the second turntable, the distance between the first connecting piece 230 and the second connecting piece 240 is changed, thereby realizing the grasping and releasing of the triangular bright bar buckle 300.

[0049] Further, the first connecting portion 210 is arranged in a U shape, including a bottom surface 212 and two side surfaces 211. The two side surfaces 211 are oppositely arranged at both ends of the bottom surface 212, and a first clamping groove for clamping the fixed clamping claw 110 is formed between the two side surfaces 211.

[0050] Specifically, the two side surfaces 211 and the bottom surface 212 are elastic. When the fixed clamping claw 110 extends into the first clamping groove, the two side surfaces 211 generate deformation in the direction away from each other, and at the same time tightly clamp the fixed clamping claw 110, so that the grasping assembly 200 is not easily detached from the fixed clamping claw 110.

[0051] Furthermore, an inclined plate 213 is further provided on one of the side surfaces 211. A sliding groove 111 is formed on one side of the fixed clamping claw 110. One end of the inclined plate 213 abuts against the sliding groove 111, which can prevent the sliding between the fixed clamping claw 110 and the grasping assembly 200 in the length direction of the bottom surface 212.

[0052] Furthermore, the inclined plate 213 is inclined gradually in the direction away from the fixed clamping claw 110 from the bottom surface 212 towards the opening of the first clamping groove; such a setting makes the friction between the inclined plate 213 and the sliding groove 111 smaller when the fixed clamping claw 110 enters the first clamping groove, and the inclined plate 213 can slide in the sliding groove 111, making it smoother for the fixed clamping claw 110 to enter the first clamping groove; when the fixed clamping claw 110 has a tendency to exit the first clamping groove, the inclined plate 213 abuts against the sliding groove 111, and the friction between the two increases. Finally, the process of the fixed clamping claw 110 entering the first clamping groove is smoother, and the connection strength between the grasping assembly 200 and the fixed clamping claw 110 after the fixed clamping claw 110 enters the first clamping groove is increased, and the grasping assembly 200 is not easily detached from the fixed clamping claw 110.

[0053] Further, the second connecting portion 220 is arranged in a V shape, including a first clamping piece 221 and a second clamping piece 222 which are fixedly connected. A second clamping groove for clamping the movable clamping claw 120 is formed between the first clamping piece 221 and the second clamping piece 222.

[0054] Further, the movable clamping claw 120 is slidably connected to the fixed clamping claw 110; an elastic portion 260 is provided between the first connecting portion 210 and the second connecting portion 220; the movable clamping claw 120 slides relative to the fixed clamping claw 110 to compress or release the elastic portion 260.

[0055] In this embodiment, an elastic part 260 is arranged between the first connecting part 210 and the second connecting part 220. When the movable claw 120 slides towards the fixed claw 110, it will drive the second connecting part 220 to compress the elastic part 260, thereby reducing the width of the grasping assembly 200 and realizing the switching of the grasping assembly 200 from the first state to the second state. Similarly, when the movable claw 120 slides away from the fixed claw 110, it will drive the second connecting part 220 to release the elastic part 260, thereby increasing the width of the grasping assembly 200 and realizing the switching of the grasping assembly 200 from the second state to the first state.

[0056] Further, the elastic part 260 is arranged in a U shape and includes a top plate 262, a first side plate 261 and a second side plate 263. One end of the first side plate 261 is connected to the top plate 262, the other end of the first side plate 261 is connected to the first connecting part 210, one end of the second side plate 263 is connected to the end of the top plate 262 away from the first side plate 261, and the other end of the second side plate 263 is connected to the second connecting part 220;

[0057] The movable claw 120 slides relative to the fixed claw 110 to change the distance between the two top plates 262.

[0058] In this embodiment, the switching between the first state and the second state is realized through the deformation among the first side plate 261, the second side plate 263 and the top plate 262, and its structure is simple and the cost is low. It should be noted that the elastic part 260 including the first side plate 261, the second side plate 263 and the top plate 262 is the optimal embodiment, and the present application can also use elastic parts such as springs to replace it.

[0059] Further, notches are formed in the top plate 262, the first side plate 261 and the second side plate 263, and the three notches are connected to form a through groove;

[0060] It further includes a transition plate 250. One end of the transition plate 250 is connected to the first connecting part 210, the other end of the transition plate 250 is connected to the first side plate 261, and the transition plate 250 is connected to the through groove.

[0061] That is, a through groove is formed at the central position of the elastic part, and this through groove can make the elastic part 260 more likely to deform and avoid the deformation of other parts of the grasping component.

[0062] At the same time, the purpose of arranging the transition plate 250 is to avoid the direct connection between the elastic part 260 and the first connecting part 210, thereby avoiding the deformation of the first connecting part 210 accordingly.

[0063] Further, the driving assembly 100 includes: a fixing frame 130, to which the fixing claw 110 is fixedly connected; a driving cylinder 140, which is rotatably connected to the fixing frame 130; a rotating block 150, which is fixedly connected to the piston rod of the driving cylinder 140. The rotating block 150 has a first hinged portion and a second hinged portion. The first hinged portion is hinged to the movable claw 120, and the second hinged portion is hinged to the fixing frame 130;

[0064] The piston rod of the driving cylinder 140 extends and retracts to drive the movable claw 120 to move in a direction towards or away from the fixing claw 110.

[0065] Further, the movable claw 120 includes a sliding portion 121 and a clamping portion 122 fixedly perpendicular to the sliding portion 121. The sliding portion 121 is slidably connected to the fixing claw 110, and the clamping portion 122 is clamped to the second connecting portion 220;

[0066] It further includes: a first hinged rod 151, one end of the first hinged rod 151 is hinged to the first hinged portion, and the other end of the first hinged rod 151 is hinged to the sliding portion 121; a second hinged rod 152, one end of the second hinged rod 152 is hinged to the second hinged portion, and the other end of the second hinged rod 152 is hinged to the fixing frame 130.

[0067] Specifically, the piston rod of the driving cylinder 140 is substantially perpendicular to the sliding direction of the movable claw 120. The driving cylinder 140 itself is rotatably connected to the fixing frame 130. When the piston rod of the driving cylinder 140 extends or retracts, the driving cylinder 140 itself can rotate relative to the fixing frame 130, thereby driving the rotating block 150 to rotate, and then causing the first hinged rod 151 and the second hinged rod 152 to rotate. The first hinged rod 151 pulls the movable claw 120 to slide in a direction towards or away from the fixing claw 110.

[0068] It should be noted that if the deformation of the elastic portion 260 is too large, it will cause damage to the elastic portion 260 or even deformation of the entire grasping assembly 200; therefore, if the piston rod is directly connected to the movable claw 120, the telescopic length of the piston rod is equal to the sliding length of the movable claw 120. Since the sliding length of the movable claw 120 should not be too large, the telescopic stroke of the piston rod needs to be precisely controlled.

[0069] To address the above difficulties, in this embodiment, by providing a rotating block 150, a first hinge rod 151, and a second hinge rod 152, the telescopic direction of the piston rod is converted into the sliding direction of the movable claw 120 that is approximately perpendicular. Moreover, the rotation of the first hinge rod 151, the second hinge rod 152, and the rotating block 150 consumes part of the telescopic stroke of the piston rod. Therefore, the sliding stroke of the movable claw 120 must be less than the telescopic stroke of the piston rod (i.e., a deceleration effect is achieved), and it is only necessary to roughly control the telescopic stroke of the piston rod within a certain range. More importantly, the angle between the first hinge rod 151 and the sliding direction of the movable claw 120 changes continuously with the telescopic movement of the piston rod. Specifically, when the piston rod extends uniformly, the angle between the first hinge rod 151 and the sliding direction of the movable claw 120 gradually increases (gradually approaches parallel), that is, the sliding speed of the movable claw 120 gradually increases, avoiding damage to the grasping assembly 200 due to excessive speed at the beginning of compressing the elastic part 260. When the piston rod shortens uniformly, the angle between the first hinge rod 151 and the sliding direction of the movable claw 120 gradually decreases (gradually approaches perpendicular), that is, the sliding speed of the movable claw 120 gradually decreases, so as to quickly release the elastic part 260 to avoid damage to the elastic part 260 due to excessive compression time.

[0070] Furthermore, a limiting block 160 is fixed on the driving cylinder 140. The piston rod of the driving cylinder 140 telescopically moves to make the rotating block 150 abut against or separate from the limiting block 160. When the rotating block 150 abuts against the limiting block 160, the movement of the movable claw 120 in the direction towards the fixed claw 110 can be restricted.

[0071] When the rotating block 150 abuts against the limiting block 160, the piston rod cannot continue to extend, and the movable claw 120 cannot continue to move in the direction towards the fixed claw 110, thereby protecting the elastic part 260 from being damaged due to excessive deformation.

[0072] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0073] In addition, in the present invention, descriptions such as "first", "second", and "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0074] In the present invention, unless otherwise clearly stipulated and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention may be understood according to specific circumstances.

[0075] In addition, the technical solutions between various embodiments of the present invention may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
