Description

Technical Field

[0001] The utility model relates to the technical field of robotic arm assembly, and particularly relates to a high-precision robotic arm assembly device. Background Technique

[0002] A robotic arm is an automated mechanical device that is most widely and practically applied in the field of robotics technology. It can accept instructions and accurately locate a certain point in three-dimensional (or two-dimensional) space for operation.

[0003] In the prior art, when assembling parts through a robotic arm, the equipment for the parts to be assembled lacks effective positioning means. When the robotic arm is assembling, the equipment to be assembled is prone to position deviation, resulting in deviation of the position of the assembled parts and inconvenience in use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the equipment for the parts to be assembled in the prior art lacks effective positioning means, and the equipment to be assembled is prone to position deviation when the robotic arm is assembling, and to propose a high-precision robotic arm assembly device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A high-precision robotic arm assembly device includes a placement plate for placing the equipment to be assembled. A robotic arm mounting seat is fixed at the top of the placement plate. A robotic arm body is rotatably mounted on the robotic arm mounting seat. A clamp for grasping parts is provided on the robotic arm body.

[0007] Wherein, two auxiliary clamping plates are provided on the upper side of the placement plate. Main clamping plates are provided at the ends of the two auxiliary clamping plates close to each other. The two main clamping plates are used for clamping the equipment to be assembled. A set of extrusion clamping components is arranged in the placement plate. The extrusion clamping components are used to drive the two main clamping plates to clamp. The extrusion clamping components and the robotic arm body are used in cooperation.

[0008] Two sets of adjusting components are respectively arranged between the two auxiliary clamping plates and the two main clamping plates for adjusting the initial distance between the two main clamping plates.

[0009] In a possible design, each set of adjusting components includes two first limiting rods slidably arranged in the auxiliary clamping plate. The main clamping plate is fixed to the side ends of the two first limiting rods. A bolt is threadedly connected in the auxiliary clamping plate. The bolt rotates at the side end of the main clamping plate.

[0010] In a possible design, the extrusion clamping assembly includes a first groove formed in the placement plate. Two connecting blocks are slidably disposed in the first groove. Two secondary clamping plates are respectively fixed to the tops of the two connecting blocks. Extrusion grooves are formed in both of the two connecting blocks. A second groove is formed in the placement plate. Two second limiting rods are fixed in the second groove. The same connecting plate is slidably disposed on the surfaces of the two second limiting rods. Two extrusion rods are fixed to the side end of the connecting plate. The two extrusion rods respectively extend outwardly and penetrate into the two extrusion grooves. The two extrusion rods are respectively in extrusion contact with the inclined surfaces of the two extrusion grooves.

[0011] In a possible design, the extrusion clamping assembly further includes an extrusion plate fixed to the top end of the connecting plate. A convex plate is fixed to the surface of the robotic arm body. The protruding section of the convex plate and the clamping jaw are on the same side. The convex plate is in extrusion contact with the extrusion plate.

[0012] In a possible design, anti-slip pads are respectively fixed to the ends of the two main clamping plates close to each other.

[0013] In a possible design, two positioning springs are fixed to the side end of the connecting plate. The side ends of the two positioning springs are respectively fixed in the second groove. The two positioning springs are respectively sleeved on the surfaces of the two second limiting rods.

[0014] In a possible design, two accommodating grooves are respectively formed in the ends of the two connecting blocks close to each other. Two reset springs are fixed in the four accommodating grooves.

[0015] In a possible design, a limiting plate for limiting the device to be assembled is fixed to the top end of the placement plate.

[0016] In this application, the device to be assembled is placed on the placement plate. The clamping jaw on the robotic arm body is used to grab the part. After grabbing, the robotic arm body rotates to move the part to the upper side of the placement plate. During the rotation of the robotic arm body, the convex plate is driven to rotate by 180°. The convex plate extrudes the extrusion plate. The extrusion plate drives the connecting plate to move. The connecting plate drives the extrusion rod to move. The extrusion rod extrudes the inclined surface of the extrusion groove, so that the two connecting blocks move towards the direction close to each other. The two connecting blocks drive the two main clamping plates to move towards the direction close to each other through the two secondary clamping plates, so as to clamp and fix the device to be assembled.

[0017] When the robotic arm body grabs the part again after assembly, the extrusion of the extrusion plate is lost, so that the positioning of the two main clamping plates on the device to be assembled is cancelled, which is convenient for removing and replacing the new device to be assembled.

[0018] Beneficial effects

[0019] In the present utility model, for the described high-precision robotic arm assembly device, through the extrusion clamping assembly, the effect of clamping and positioning the device to be assembled after adjusting the direction of the robotic arm body can be achieved;

[0020] In the present utility model, for the described high-precision robotic arm assembly device, through the adjusting assembly, the effect of adjusting the initial distance between the two main clamping plates can be achieved;

[0021] In the present utility model, through the combined use of the extrusion clamping assembly and the adjusting assembly, precise clamping of the device to be assembled is realized, the assembly precision is improved. The design of the adjusting assembly enables the distance between the main clamping plates to be flexibly adjusted according to the size of the device to be assembled, enhancing the versatility and adaptability of the device. Through the automatic cooperation of the robotic arm and the extrusion clamping assembly, automatic control of the assembly process is achieved, improving production efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Embodiment 1

[0028] Refer to Figures 1-3, a high-precision robotic arm assembly device, which is applied in the field of robotic arm assembly technology. It includes a placement plate 1, a robotic arm mounting base 2, a robotic arm body 3, auxiliary clamping plates 4, main clamping plates 5, as well as an extrusion clamping assembly and an adjustment assembly. The placement plate 1 serves as the base of the entire device, and the robotic arm mounting base 2 is fixed to its upper end. The robotic arm body 3 is installed on the robotic arm mounting base 2 through a rotating mechanism. A gripper is provided at the end of the robotic arm body 3 for grasping parts for assembly.

[0029] Above the placement plate 1, two auxiliary clamping plates 4 are provided, and a main clamping plate 5 is provided at the proximal end of each auxiliary clamping plate 4. The two main clamping plates 5 are jointly used to clamp the device to be assembled to ensure stability during the assembly process. In order to adjust the initial distance between the two main clamping plates 5 to adapt to devices to be assembled of different sizes, the present invention designs an adjustment assembly.

[0030] Each set of adjustment assemblies includes two first limiting rods 6, which are slidably installed in the auxiliary clamping plates 4, and the main clamping plates 5 are fixed to the side ends of the two first limiting rods 6. By rotating the bolt 7 threadedly connected in the auxiliary clamping plate 4, one end of the bolt 7 contacts the main clamping plate 5 and applies pressure, thereby pushing the main clamping plate 5 to slide along the first limiting rod 6 to achieve distance adjustment.

[0031] The extrusion clamping assembly mainly includes components such as a first groove 8, a connecting block 9, an extrusion groove 15, a second groove 10, a second limiting rod 19, a connecting plate 18, and an extrusion rod 16. The two connecting blocks 9 are respectively slidably installed in the first groove 8, and the auxiliary clamping plates 4 are fixed to the tops of the connecting blocks 9. The connecting plate 18 slides in the second groove 10 through two second limiting rods 19, and the extrusion rod 16 fixed to the side end of the connecting plate 18 extends into the extrusion groove 15 in the connecting block 9 and forms an extrusion contact with the inclined surface of the extrusion groove 15. When the connecting plate 18 moves, through the interaction between the extrusion rod 16 and the extrusion groove 15, it drives the connecting block 9 and the auxiliary clamping plate 4 to move to both sides, and then drives the main clamping plate 5 to clamp the device to be assembled.

[0032] A convex plate 12 is fixed to the surface of the robotic arm body 3, and the protruding section of the convex plate 12 is on the same side as the gripper. When the robotic arm body 3 rotates to a specific position, the convex plate 12 contacts and applies pressure to the extrusion plate 11 fixed to the top of the connecting plate 18, pushing the connecting plate 18 to move, thereby triggering the extrusion clamping action.

[0033] Embodiment 2

[0034] Reference Figures 1-3, improved on the basis of Embodiment 1: Anti-slip pads are fixed to the clamping ends of the two main clamping plates 5 to increase the friction during clamping and prevent the equipment to be assembled from slipping. Two positioning springs 20 are fixed to the side end of the connecting plate 18, sleeved on the surfaces of the two second limiting rods 19 respectively, and fixed in the second grooves 10, which are used to provide a restoring force after the extrusion action is completed. In addition, receiving grooves 14 are formed at the ends of the two connecting blocks 9 close to each other, and restoring springs 13 are fixed in the receiving grooves 14 to further ensure the stability of the clamping action and the accuracy of restoration.

[0035] In order to further improve the stability of the equipment to be assembled during the assembly process, a limiting plate 21 is further fixed to the top of the placing plate 1, which is used to perform additional limitation on the equipment to be assembled.

[0036] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
