Description

Technical Field

[0001] This utility model relates to the field of robotic arm base technology, specifically a robotic arm base that is securely installed. Background Technology

[0002] Robotic arms are the most widely used automated mechanical devices in the field of mechanical technology, and can be found in fields such as industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing and space exploration.

[0003] According to a publicly disclosed design for a stable robotic arm base (publication number: CN214418869U), the aforementioned application utilizes a sliding plate, a first pressure plate, and clamping bolts to clamp and fix the robotic arm base during installation, achieving a stable effect. This solves the problem of poor fixation when the robotic arm is installed on the base, effectively preventing positional shifts during use and improving the installation accuracy of the robotic arm.

[0004] However, despite its excellent stability, this robotic arm base exhibits significant shortcomings in actual installation and dismantling. Specifically, the use of multiple complex fixing methods results in cumbersome installation and dismantling procedures, time-consuming operations, and low work efficiency. This not only increases the labor intensity of operators but may also affect the overall operating efficiency of the production line, especially in situations requiring frequent robotic arm changes or position adjustments. While some methods improve stability, they are time-consuming, labor-intensive, and inefficient during actual installation and dismantling. Utility Model Content

[0005] The purpose of this invention is to provide a stable robotic arm base to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stable robotic arm base, comprising a base, a robotic arm mounting seat disposed on the top of the base, an installation groove being provided on the top of the base, and docking components and linkage components being provided inside and on the surface of the base and the robotic arm mounting seat;

[0007] The docking components include:

[0008] The cavity is used to stabilize the circular plate;

[0009] The circular plate is used to drive the connecting holes to move synchronously.

[0010] The connecting hole is used to drive the movable rod and the locking block to move radially synchronously.

[0011] Preferably, the cavity is formed inside the base, and a circular plate is rotatably connected to the inner wall of the cavity. A connecting hole is formed on the surface of the circular plate, and a movable rod abuts against the inner wall of the connecting hole. A locking block is fixed to the surface of the movable rod, and the locking block is slidably connected to the inner wall of the cavity. A spring is fixed to the surface of the locking block, and the end of the spring away from the locking block is fixed to the inner wall of the cavity. The end of the locking block away from the spring penetrates the base. A connecting cavity and a stabilizing cavity are formed inside the base. All are interconnected. The surface of the circular plate is fixed with locking teeth, which are located in the connecting cavity. The inner wall of the stabilizing cavity is rotatably connected with a gear, which meshes with the locking teeth. A rotating rod is fixed to the top of the gear, and the top of the rotating rod passes through the base and is rotatably connected to the base. The robotic arm mounting base is installed into the mounting groove. Through spring 1, movable rod, connecting hole, and circular plate, each locking block and movable rod moves radially synchronously. When the position of the locking block is parallel to the slot, spring 1 is released, and the locking block moves into the slot, thus making the robotic arm mounting base and the base mutually limit and stabilize each other.

[0012] Preferably, the linkage assembly includes a movable column rotatably connected to the top of a rotating rod. A groove is formed at the bottom of the movable column, and a sliding plate is slidably connected to the inner wall of the groove. A second spring is fixed to the bottom of the sliding plate, and the bottom of the second spring is fixed to the bottom of the inner wall of the groove. A connecting column is fixed to the bottom of the sliding plate, and a stabilizing groove is formed on the surface of the connecting column. A linkage plate is slidably connected to the inner wall of the stabilizing groove, and a third spring is fixed to the surface of the linkage plate. The end of the third spring away from the linkage plate is fixed to the inner wall of the stabilizing groove. The top of the rotating rod... The slide has a receiving groove, and the inner wall of the receiving groove has an abutment groove. A top rod is fixed to the top of the slide, and a pressure plate is fixed to the top of the top rod. The top of the top rod passes through the movable column, and the top rod and the movable column are slidably connected. When the pressure plate is pressed down, the top rod drives the slide, connecting column, and linkage plate to move down. The linkage plate enters the abutment groove. The rotation synchronously drives the rotating rod and gear to rotate synchronously. The gear drives the locking teeth and the circular plate to rotate. By rotating the movable column, the connecting hole drives the movable rod to move synchronously, which can drive the locking block to disengage from the locking groove, release the limitation on the robotic arm mounting base, and facilitate disassembly and maintenance.

[0013] Preferably, the connecting hole is arc-shaped, so that when the circular plate rotates, it can drive the movable rod and the locking block to move radially in sync.

[0014] Preferably, the end of the locking block away from the spring is set as an inclined surface, which can drive the locking block to move synchronously when it is pressed.

[0015] Preferably, the side of the connecting plate closest to the rotating rod is set as an inclined surface, which allows the connecting plate to move into the stabilizing groove when it is abutted.

[0016] Compared with the prior art, this utility model provides a stable robotic arm base, which has the following advantages:

[0017] 1. The robustly installed robotic arm base, through the set docking components, allows the robotic arm mounting base to be installed into the mounting groove during installation. Through spring 1, movable rod, connecting hole, and circular plate, the locking blocks and movable rod move radially synchronously. When the locking block is parallel to the slot, spring 1 is released, and the locking block moves into the slot, thus making the robotic arm mounting base and the base mutually limit and stabilize each other, facilitating installation.

[0018] 2. The securely installed robotic arm base, through its linkage components, ensures that when the movable column is accidentally touched externally, its rotation will not cause the rotating rod to rotate, thus avoiding affecting the stability of the robotic arm mounting base and the base. When disassembly and maintenance are required, pressing down the pressure plate causes the push rod to move the sliding plate, connecting column, and linkage plate downwards. The linkage plate enters the contact groove, and its rotation synchronously drives the rotating rod and gear to rotate. The gear drives the locking teeth and circular plate to rotate. By rotating the movable column, the connecting hole drives the movable rod to move synchronously, which in turn causes the locking block to disengage from the locking groove, releasing the limitation on the robotic arm mounting base and facilitating disassembly and maintenance.

Detailed Implementation

[0025] like Figures 1-5As shown, this utility model provides a technical solution: a stable robotic arm base, including a base 1, a robotic arm mounting seat 2 above the base 1, a mounting groove 3 on the top of the base 1, and a docking assembly 4 and a linkage assembly 5 provided inside and on the surface of the base 1 and the robotic arm mounting seat 2; the docking assembly 4 includes: a cavity 40, a connecting cavity 41, a stabilizing cavity 42, a circular plate 43, a movable rod 44, a connecting hole 45, a locking block 46, a locking groove 47, a gear 48, a rotating rod 49, a locking tooth 400, and a spring 401; the cavity 40 is used to stabilize the circular plate 43. The circular plate 43 drives the connecting hole 45 to move synchronously. The connecting hole 45 drives the movable rod 44 and the locking block 46 to move radially synchronously. The cavity 40 is opened inside the base 1. The inner wall of the cavity 40 is rotatably connected to the circular plate 43. The surface of the circular plate 43 has a connecting hole 45. The inner wall of the connecting hole 45 abuts against the movable rod 44. The surface of the movable rod 44 is fixed with a locking block 46. The locking block 46 is slidably connected to the inner wall of the cavity 40. A spring 401 is fixed on the surface of the locking block 46. The end of the spring 401 away from the locking block 46 is... Fixed to the inner wall of cavity 40, the end of the locking block 46 away from spring 401 passes through the base 1. The base 1 has a connecting cavity 41 and a stabilizing cavity 42. Cavity 40, connecting cavity 41, and stabilizing cavity 42 are interconnected. The surface of circular plate 43 is fixed with locking teeth 400, which are located in the connecting cavity 41. The inner wall of stabilizing cavity 42 is rotatably connected to gear 48, which meshes with locking teeth 400. The top of gear 48 is fixed with rotating rod 49, which passes through the base 1 and is rotatably connected to the base 1. The connecting hole 45 is set to be arc-shaped, and the end of the locking block 46 away from the spring 401 is set to be inclined. The robotic arm mounting base 2 is installed into the mounting groove 3. The surface of the robotic arm mounting base 2 abuts against the inclined surface of the locking block 46. Through the spring 401, the movable rod 44, the connecting hole 45, and the circular plate 43, the locking blocks 46 and the movable rod 44 move radially synchronously. When the position of the locking block 46 is parallel to the slot 47, the spring 401 is released, which can drive the locking block 46 to move into the slot 47, so that the robotic arm mounting base 2 and the base 1 are mutually limited and stable, which facilitates installation.

[0026] The linkage assembly 5 includes a movable column 50, which is rotatably connected to the top of the rotating rod 49. A groove 51 is formed at the bottom of the movable column 50, and a sliding plate 52 is slidably connected to the inner wall of the groove 51. A second spring 54 is fixed to the bottom of the sliding plate 52, and the bottom of the second spring 54 is fixed to the bottom of the inner wall of the groove 51. A connecting column 53 is fixed to the bottom of the sliding plate 52, and a stabilizing groove 55 is formed on the surface of the connecting column 53. A linkage plate 56 is slidably connected to the inner wall of the stabilizing groove 55, and a third spring 57 is fixed to the surface of the linkage plate 56. One end of the third spring 57 away from the linkage plate 56 is fixed to the inner wall of the stabilizing groove 55. A receiving groove 58 is formed at the top of the rotating rod 49, and an abutment groove 59 is formed on the inner wall of the receiving groove 58. A top rod 500 is fixed to the top of the sliding plate 52, and a pressure plate 501 is fixed to the top of the top rod 500. The movable column 50 is slidably connected to the push rod 50. The side of the connecting plate 56 near the rotating rod 49 is set as an inclined surface. The pressing plate 501 is pressed down. The push rod 500 drives the sliding plate 52, the connecting column 53, and the connecting plate 56 to move down synchronously. Its inclined surface abuts against the inner wall of the receiving groove 58. The connecting plate 56 moves into the stabilizing groove 55. The spring 3 57 is compressed. The movable column 50 is rotated. When the position of the connecting plate 56 is parallel to the contact groove 59, the spring 3 57 is released. The connecting plate 56 returns to the contact groove 59. The surface of the connecting plate 56 abuts against the inner wall of the contact groove 59. The rotating rod 49 and the gear 48 rotate synchronously. The gear 48 drives the locking tooth 400 and the circular plate 43 to rotate. Through the connecting hole 45, the movable rod 44 moves synchronously. This can drive the locking block 46 to disengage from the locking groove 47, thereby releasing the limitation on the robotic arm mounting base 2.

[0027] When the robotic arm needs to be installed, the robotic arm mounting base 2 is installed into the mounting slot 3. At this time, the surface of the robotic arm mounting base 2 abuts against the inclined surface of the locking block 46, and the locking block 46 moves into the cavity 40. Simultaneously, the spring 401 is compressed, and the locking block 46 drives the movable rod 44 to move synchronously. The surface of the movable rod 44 abuts against the inner wall of the connecting hole 45, which drives the circular plate 43 to rotate clockwise, so that each locking block 46 and movable rod 44 moves radially synchronously. When the position of the locking block 46 is parallel to the slot 47, the spring 401 is released, which drives the locking block 46 to move into the slot 47. At the same time, the movable rod 44 resets, and drives the circular plate 43 to rotate and reset through the connecting hole 45. This makes the robotic arm mounting base 2 and the base 1 mutually limit and stabilize each other, which is convenient for installation. When the movable column 50 is accidentally touched from the outside, the rotation of the movable column 50 will not drive the rotating rod 49 to rotate, so as to avoid affecting the robotic arm installation. To ensure the stability of the mounting base 2 and the base 1, when disassembly and maintenance are required, the pressure plate 501 is pressed down, and the top rod 500 drives the sliding plate 52 and the connecting column 53 to move down. When the connecting plate 56 moves down synchronously, its inclined surface abuts against the inner wall of the receiving groove 58, which can drive the connecting plate 56 to move into the stabilizing groove 55. The spring 3 57 is compressed. At this time, the operator rotates the movable column 50. When the position of the connecting plate 56 is parallel to the contact groove 59, the spring 3 57 is released, and the connecting plate 56 returns to its original position and enters the contact groove 59. At this time, the surface of the connecting plate 56 abuts against the inner wall of the contact groove 59, which can synchronously drive the rotating rod 49 and the gear 48 to rotate synchronously. At this time, the gear 48 drives the locking tooth 400 and the circular plate 43 to rotate synchronously. Through the connecting hole 45, the movable rod 44 moves synchronously, which can drive the locking block 46 to disengage from the locking groove 47, thus releasing the limitation on the robotic arm mounting base 2. At this time, it can be disassembled normally for convenient maintenance.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
