Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a robot neck connection device. Background Technology

[0002] Intelligent robots can replace humans in performing some heavy work or assist humans in performing some complex tasks, liberating labor and greatly helping human production and life. One of the main components of an intelligent robot is its neck, which needs to be fitted onto the robot's body.

[0003] For example, the authorization announcement number "CN215395321U" is titled "Intelligent Robot Neck Connection Device". It utilizes the elasticity of the first and second springs to reset and move the adjusting ring and locking frame, and uses the locking frame to quickly lock the mounting base, thereby achieving rapid connection and assembly of the robot neck. However, the intelligent robot neck connection device requires the use of a spring-driven adjusting block to restrict the robot neck during installation and connection. However, the adjusting block, which is controlled laterally by the spring, can only prevent the robot neck from falling off the robot body. The gap at the installation connection point will cause a certain degree of shaking and vibration between the robot neck and the head above it and the robot body. This will cause significant interference to the equipment and parts above the robot neck and reduce the neck installation stability of the intelligent robot neck connection device. Utility Model Content

[0004] The purpose of this invention is to solve the problem of unstable installation of existing intelligent robot neck connection devices, and to propose a robot neck connection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A robot neck connection device is designed, comprising a robot body, a robot neck, and a connecting seat. The connecting seat is fixedly connected to the lower end of the robot neck. Robot neck clamping and fixing structures are provided on both sides of the connecting seat. An installation groove is fixedly opened on the inner side of the robot body. Robot neck alignment and installation structures are provided on the inner wall of the robot body.

[0007] Preferably, the robot neck clamping and fixing structure includes movable grooves and bolts. Two bolts are threadedly connected to the top two sides of the outer wall of the robot body. Two movable grooves are fixedly opened on both sides of the outer wall of the robot body. Two rotating blocks are rotatably connected to the bottom of the movable grooves through bearings. An elastic metal block is movably connected above the two rotating blocks. A clamping plate is fixedly connected to one side of the outer wall of the elastic metal block, and a toggle block is fixedly connected to the other side of the outer wall of the two elastic metal blocks.

[0008] Preferably, the bottom ends of the two bolts abut against the top end of the lower elastic metal block, and the bottom surfaces of the two abutting plates are movably connected to the upper surface of the connecting seat.

[0009] Preferably, the robot neck alignment and mounting structure includes vertical grooves and pads. Multiple vertical grooves are fixedly formed on the inner wall of the robot body. Multiple splicing strips are slidably connected to the inner side of the multiple vertical grooves. Multiple filling blocks are fixedly connected to the side walls of the multiple splicing strips. Multiple protrusions are fixedly connected to the inner walls of the multiple vertical grooves. Two pads are fixedly installed at the bottom of the inner wall of the robot body.

[0010] Preferably, the two ends of the plurality of protrusions are movably connected to the filling block, and the top end of the pad is movably connected to the lower end of the connecting seat.

[0011] Preferably, the inner side of the mounting groove is slidably connected to the outer wall of the connecting seat.

[0012] The robot neck connection device proposed in this utility model has the following advantages: the bolt is tightened by rotating downwards, and the bolt pushes the lower elastic metal block down.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figures 1-6 In this embodiment, a robot neck connection device includes a robot body 1, a robot neck 2, and a connecting seat 3. The connecting seat 3 is fixedly connected to the lower end of the robot neck 2. Robot neck clamping and fixing structures 5 are provided on both sides of the connecting seat 3. The robot body 1 belongs to the prior art disclosed in the prior art documents, and the robot neck 2 also belongs to the prior art documents. Therefore, the specific working principle and structure of the robot are omitted here. An installation groove 4 is fixedly opened on the inner side of the robot body 1. The installation groove 4 can be easily connected and assembled with the circular connecting seat 3. A robot neck alignment and installation structure 6 is provided on the inner wall of the robot body 1.

[0023] The robot neck clamping and fixing structure 5 includes a movable groove 54 and bolts 56. Two bolts 56 are threadedly connected to the top two sides of the outer wall of the robot body 1. The movable groove 54 is carved on the top two sides of the robot body 1. The movable groove 54 provides a certain space for the rotating block 51 to drive the clamping plate 52 to rotate. The two movable grooves 54 are fixedly opened on the outer wall of the robot body 1. The two rotating blocks 51 are rotatably connected to the bottom of the movable groove 54 through bearings. When the robot neck 2 needs to be installed normally, the two moving blocks 55 on both sides are manually moved first. The rotating blocks 51 drive the two clamping plates 52 to rotate outward by 180 degrees using the bearings.

[0024] In this way, the clamping plate 52 leaves the internal space of the mounting slot 4, and the connecting seat 3 drives the robot neck 2 to be placed downward into the inner side of the robot body 1. The clamping plate 52 is rotated in the opposite direction towards the connecting seat 3 until the clamping plate 52 falls above the connecting seat 3. An elastic metal block 53 is movably connected above the two rotating blocks 51. The elastic metal block 53 is made of high-toughness stainless steel material that is not easy to break or bend. The clamping plate 52 is fixedly connected to one side of the outer wall of the elastic metal block 53.

[0025] Two elastic metal blocks 53 are fixedly connected to a toggle block 55 on the other side of their outer walls. When the bolt 56 is tightened by rotating it downwards, the bolt 56 pushes the lower elastic metal block 53 down. The elastic metal block 53 deforms under pressure and uses the deformation amplitude to drive the abutment plate 52 to press down firmly above the connecting seat 3. In this way, the connecting seat 3 can be installed and fixed by the downward pressure from the top, and it is not easy to create room for movement.

[0026] The bottom ends of the two bolts 56 abut against the top end of the elastic metal block 53 below, the bottom surfaces of the two abutting plates 52 are movably connected to the upper surface of the connecting seat 3, and the inner side of the mounting groove 4 is slidably connected to the outer wall of the connecting seat 3.

[0027] Working principle:

[0028] The robot neck connector is used to dock and assemble the neck, head, and lower body of current intelligent robots.

[0029] The robot body 1 is existing technology already disclosed in the prior art document, and the robot neck 2 is also existing content in the prior art document. Therefore, the specific working principle and structure of the robot are omitted here. The mounting slot 4 can be easily docked and assembled with the circular connecting seat 3.

[0030] Installation and fixing process of robot neck connector:

[0031] When the robot neck 2 needs to be installed normally, first manually move the two moving blocks 55 on both sides. The rotating block 51 uses the bearing to drive the two clamping plates 52 to rotate outward by 180 degrees. In this way, the clamping plates 52 leave the internal space of the mounting slot 4. The connecting seat 3 drives the robot neck 2 to be placed downward into the inner side of the robot body 1. Then, rotate the clamping plates 52 in the opposite direction towards the connecting seat 3 until the clamping plates 52 fall above the connecting seat 3.

[0032] Finally, rotate the bolt 56 downwards to tighten it. The bolt 56 pushes the lower elastic metal block 53 downwards. The elastic metal block 53 is made of high-toughness stainless steel that is not easy to break or bend. The elastic metal block 53 deforms under pressure and uses the deformation amplitude to drive the clamping plate 52 to press down firmly above the connecting seat 3. In this way, the connecting seat 3 can be installed and fixed by the downward pressure from the top, which makes it less likely to create space for movement and improves the installation stability of the robot neck connecting device.

[0033] Example 2:

[0034] Please see Figures 1-6In this embodiment, a robot neck connection device includes a robot neck alignment and mounting structure 6, which includes a vertical groove 61 and a pad 65. Multiple vertical grooves 61 are fixedly opened on the inner wall of the robot body 1. The vertical groove 61 is a groove that is vertically chiseled and faces the inner side of the mounting groove 4. When installing and positioning the connecting seat 3, the splicing strip 62 protruding and fixed on the outer wall of the connecting seat 3 is fixed.

[0035] In this way, the splicing strips 62 can be inserted into the corresponding vertical slots 61 in sequence, thereby achieving the positioning of the connecting seat 3. Multiple splicing strips 62 are slidably connected to the inner side of multiple vertical slots 61, and multiple filling blocks 64 are fixedly connected to the side walls of multiple splicing strips 62. The filling blocks 64 are made of rubber material, and the protrusions 63 are made of semi-circular plastic material. In this way, the filling blocks 64 rub against the protrusions 63 under the pushing action of the splicing strips 62. The friction and pressing force can be used to stabilize the splicing strips 62 and the inner connecting seat 3, so that the connecting seat 3 is not easy to shake.

[0036] Multiple protrusions 63 are fixedly connected to the inner walls of multiple vertical grooves 61. Two pads 65 are fixedly installed at the bottom of the inner wall of the robot body 1. The two ends of the multiple protrusions 63 are movably connected to the filling block 64. The top of the pad 65 is movably connected to the bottom of the connecting seat 3. The pad 65 is made of rubber material and can buffer the impact force of the upper connecting seat 3 falling and assembling.

[0037] Working principle:

[0038] The vertical groove 61 is a vertically chiseled groove facing the inside of the mounting groove 4. When installing and positioning the connecting seat 3, the splicing strip 62 protrudes and is fixed on the outer wall of the connecting seat 3. In this way, the splicing strip 62 can be inserted into the corresponding vertical groove 61 in sequence, thereby realizing the positioning of the connecting seat 3. The filling block 64 is made of rubber material, and the protrusion 63 is made of semi-circular plastic material. In this way, the filling block 64 rubs against the protrusion 63 under the pushing action of the splicing strip 62. The friction and pressing force can be used to stabilize the splicing strip 62 and the firmness of the inner connecting seat 3, and the connecting seat 3 is not easy to shake. The pad 65 is made of rubber material, and the pad 65 can buffer the impact force of the upper connecting seat 3 falling and splicing.
