Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to an adjustable robotic arm mounting base. Background Technology

[0002] The robotic arm mount provides stable support for the robotic arm, ensuring that it remains in the desired position and angle during operation, reducing swaying and displacement, and improving the accuracy and safety of operation.

[0003] According to a public disclosure of an adjustable robotic arm mounting base (Publication No.: CN220408726U), the aforementioned application utilizes an adjustment mechanism in the device to adjust the position of the mounting screw holes on the mounting base. The robotic arm is moved directly above the mounting base, and the worm gear is rotated. The worm gear drives the drive screw to rotate via the worm wheel. The rotating drive screw drives the support rod and connecting seat to move left and right via the adjusting nut. Simultaneously, the adjusting screw is rotated, causing the drive rack to move back and forth. The back-and-forth movement of the drive rack drives the rack and adjusting plate to slide via the transmission gear. The sliding adjusting plate drives the connecting seat to move back and forth, aligning the mounting screw holes on the top of the connecting seat with the mounting bolts on the robotic arm. This makes installation more convenient and solves the problem of existing robotic arm mounting bases requiring constant adjustment of the robotic arm position to align the mounting bolts with the mounting screw holes on the mounting base, which is time-consuming and laborious.

[0004] The aforementioned patent aligns the mounting screw holes with the mounting bolts on the robotic arm by moving the connecting seat back and forth. However, the spacing of the mounting bolts on different models of robotic arms varies, and the aforementioned patent cannot freely adjust the spacing between multiple sets of mounting screw holes. Therefore, it cannot adapt to more models of robotic arms and has low practicality. Utility Model Content

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

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable robotic arm mounting base, comprising a base, a mounting block slidably connected to the inner wall of the base, bolt holes provided on the mounting block, an adjustment mechanism provided on the base, and a support mechanism provided on the base, the adjustment mechanism comprising:

[0007] A threaded rod is rotatably connected to the inner wall of the base. A slider is threadedly connected to the outer wall of the threaded rod. A connecting rod is hinged to the outer wall of the slider. The end of the connecting rod away from the slider is hinged to the bottom of the mounting block. By setting the slider and the connecting rod to cooperate, the mounting block can be pushed, so that the mounting block slides on the inner wall of the base.

[0008] A worm gear, which is fixedly mounted on the bottom of the threaded rod;

[0009] A worm gear is rotatably connected to the inner wall of the base and passes through the base. A knob is fixedly installed on the outer wall of the worm gear. The worm gear meshes with a worm wheel. By setting the worm gear and worm wheel together, the threaded rod can be driven to rotate on the inner wall of the base.

[0010] Preferably, the support mechanism includes a support plate that is slidably connected to the inner wall of the base. The stability of the base can be improved by setting the support plate.

[0011] Preferably, a side plate is fixedly installed on the top of the support plate.

[0012] Preferably, the side plate has an inclined groove.

[0013] Preferably, a guide rod is fixedly installed on the outer wall of the slider.

[0014] Preferably, the outer wall of the guide rod is attached to the inner wall of the inclined groove, and the support plate can be pushed by the guide rod in conjunction with the inclined groove and the side plate.

[0015] Compared with the prior art, this utility model provides an adjustable robotic arm mounting base, which has the following advantages:

[0016] 1. This adjustable robotic arm mounting base allows the worm gear to be rotated via a knob, which, in conjunction with the worm wheel and threaded rod, drives the slider to move up and down. The up and down movement of the slider, in conjunction with the connecting rod, allows for free adjustment of the spacing between multiple sets of mounting blocks. This, in turn, allows for free adjustment of the spacing between bolt holes, enabling the mounting of different models of robotic arms onto the base and enhancing the base's practicality.

[0017] 2. The adjustable robotic arm mounting base slides upward via a slider. Simultaneously, in conjunction with the guide rod, inclined groove, and side plate, it can drive the support plate to slide outward from the inner wall of the base. At this time, the support plate will expand the support area of ​​the base, so that the base can support a larger robotic arm and improve the stability of the robotic arm.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: an adjustable robotic arm mounting base, including a base 1, with mounting blocks 2 slidably connected to the inner wall of the base 1. The mounting blocks 2 have bolt holes 3. When a robotic arm needs to be mounted on the base 1, the robotic arm is first placed on the base 1, and then the mounting bolts on the robotic arm are connected to the bolt holes 3. An adjustment mechanism 4 is provided on the base 1, which allows adjustment of the spacing between multiple sets of mounting blocks 2, thus enabling the mounting of different models of robotic arms on the base 1. A support mechanism 5 is provided on the base 1, which expands the support area of ​​the base 1, thereby improving the stability of the base 1 and allowing it to support larger robotic arms.

[0024] The aforementioned adjustment mechanism 4 includes a threaded rod 41, a worm gear 42, a worm 43, a slider 44, a connecting rod 45, and a knob 46. The threaded rod 41 is rotatably connected to the inner wall of the base 1, and the slider 44 is threadedly connected to the outer wall of the threaded rod 41. When the threaded rod 41 rotates, it drives the slider 44, which is threadedly connected to it, to move up and down on the outer wall of the threaded rod 41. The connecting rod 45 is hinged to the outer wall of the slider 44, and the end of the connecting rod 45 away from the slider 44 is hinged to the bottom of the mounting block 2. When the slider 44 moves upward on the outer wall of the threaded rod 41, the slider 44 pushes the connecting rod. 45, causing the connecting rod 45 to push the mounting block 2. At this time, the mounting block 2 will slide on the inner wall of the base 1 and gradually move away from the threaded rod 41. The worm wheel 42 is fixedly installed at the bottom of the threaded rod 41. The worm 43 is rotatably connected to the inner wall of the base 1 and passes through the base 1. A knob 46 is fixedly installed on the outer wall of the worm 43. The worm 43 meshes with the worm wheel 42. By rotating the worm 43 through the knob 46, the worm 43 will drive the worm wheel 42 that it meshes with to rotate. The worm wheel 42 will drive the threaded rod 41 to rotate on the inner wall of the base 1.

[0025] The aforementioned support mechanism 5 includes a support plate 51, a side plate 52, a sloping groove 53, and a guide rod 54. The support plate 51 is slidably connected to the inner wall of the base 1. When the support plate 51 slides outward from the inner wall of the base 1, the support area of ​​the base 1 can be expanded through the support plate 51 so that the base 1 can support a larger model of robotic arm. The side plate 52 is fixedly installed on the top of the support plate 51. The sloping groove 53 is opened on the side plate 52. The guide rod 54 is fixedly installed on the outer wall of the slider 44. The outer wall of the guide rod 54 is attached to the inner wall of the sloping groove 53. When the slider 44 moves upward on the outer wall of the threaded rod 41, the guide rod 54 will move against the inner wall of the sloping groove 53. At the same time, the guide rod 54 will squeeze the side plate 52, so that the side plate 52 pushes the support plate 51.

[0026] Working principle: Rotating the worm gear 43 via knob 46 causes the meshing worm wheel 42 to rotate. The rotation of the worm wheel 42, in turn, causes the threaded rod 41 to rotate on the inner wall of the base 1. Simultaneously, the rotation of the threaded rod 41 causes the threaded slider 44, which is threadedly connected to it, to move up and down on the outer wall of the threaded rod 41. When the slider 44 moves upward on the outer wall of the threaded rod 41, it pushes the connecting rod 45, causing the connecting rod 45 to push the mounting block 2. At this time, the mounting block 2 slides on the inner wall of the base 1 and gradually moves away from the threaded rod 41. Simultaneously, the distance between multiple sets of mounting blocks 2 gradually increases, thus increasing the distance between the bolt holes 3 on the mounting blocks 2. This allows the mounting bolts on the robotic arm to be connected inside the bolt holes 3. Furthermore, the distance between the bolt holes 3 can be freely adjusted by sliding the mounting blocks 2, allowing the base 1 to adapt to different models of robotic arms, thus increasing its practicality.

[0027] When the slider 44 moves upward on the outer wall of the threaded rod 41, the slider 44 will drive the guide rod 54 to move upward synchronously. As the guide rod 54 moves upward, it will move against the inner wall of the inclined groove 53. At the same time, the guide rod 54 will squeeze the side plate 52, causing the side plate 52 to push the support plate 51. At this time, the support plate 51 will slide outward on the inner wall of the base 1. The support plate 51 will expand the support area of ​​the base 1 so that the base 1 can support a larger model of robotic arm and improve the stability of the robotic arm.

[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.
