Description
Technical Field
[0001] This utility model relates to the field of robot component manufacturing technology, and in particular to a robot arm connection device. Background Technology
[0002] For the processing of robot parts, robots are often used for loading and unloading, while the robot arm needs to be mounted on the ground with the help of a base.
[0003] A search revealed a prior art connection structure for an industrial robot arm (publication number: CN217915394U), comprising a base plate, two first positioning plates fixedly connected to the upper surface of the base plate, four positioning screws fixedly connected to the upper surface of the base plate, a pressure plate provided above the base plate, four through holes opened on the upper surface of the pressure plate, the top end of each positioning screw passing through the through hole and extending to the top of the pressure plate, a locking cap threadedly connected to the outer surface of each positioning screw, and two second positioning plates fixedly connected to the bottom surface of the pressure plate.
[0004] In existing technologies, only the installation height of the robot arm can be adjusted, but the installation angle of the robot arm cannot be fine-tuned. Even if the robot arm has the characteristic of moving in multiple axes, the position on the ground will determine the maximum movement angle and position of the robot arm. It is necessary to adjust the position of the robot arm according to the actual production needs of the factory.
[0005] To address this, we propose a robotic arm connection device. Utility Model Content
[0006] The present invention mainly solves the above-mentioned technical problem of not being able to adjust the installation angle of the robotic arm, and provides a robotic arm connection device.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a robot arm connection device, comprising:
[0008] The lower fixed base has a liftable upper fixed base on its top, and the upper fixed base has a horizontally rotatable mounting base on its top.
[0009] A limiting component is provided between the mounting base and the upper fixed base to lock the angle of the mounting base. The limiting component includes a pressure plate, protrusions and thrust grooves. The mounting base has several thrust grooves. Several protrusions are fixedly installed on the bottom of the pressure plate. The protrusions can be inserted into the thrust grooves to restrict the rotation of the mounting base. The pressure plate is locked and fixed to the upper fixed base by bolts.
[0010] In a preferred embodiment of this utility model, the mounting base includes an upper circular plate and a lower circular plate with different diameters. The diameter of the upper circular plate is smaller than that of the lower circular plate. A rotating shaft is fixedly provided at the bottom of the lower circular plate, and a shaft hole is provided at the top of the upper mounting base. The rotating shaft is rotatably disposed in the shaft hole.
[0011] In a preferred embodiment of this utility model, the pressure plate is a rectangular plate, and a circular hole is provided through the center of the top of the pressure plate, with the circular hole fitting with the upper circular plate of the mounting base.
[0012] In a preferred embodiment of this utility model, the thrust groove is a semi-circular hole, and several identical thrust grooves are equidistantly arranged at the edge of the lower circular plate of the mounting base. The protrusion is a cylinder, and the diameter of the protrusion is equal to the diameter of the thrust groove.
[0013] As a preferred embodiment of this utility model, the limiting component further includes mounting cylinders. A mounting cylinder is fixedly installed at each of the four corners of the bottom of the pressure plate. The top of the upper fixing seat has threaded holes that correspond one-to-one with the mounting cylinders. Bolts pass through the mounting cylinders and connect with the threaded holes to lock and limit the pressure plate.
[0014] In a preferred embodiment of this utility model, a limiting rod is fixedly installed at the bottom of the upper fixed seat, and the limiting rod is slidably connected to the lower fixed seat.
[0015] In a preferred embodiment of this utility model, a sleeve is fixedly installed on the top of the lower fixed seat, the sleeve is threadedly connected to a threaded rod, the threaded rod is rotatably connected to the upper fixed seat, and the threaded rod is also threadedly connected to a nut for locking.
[0016] This invention provides a robot arm connection device. It has the following advantages:
[0017] 1. This robotic arm connection device uses a liftable upper fixed seat in conjunction with a horizontally rotatable mounting seat. The robotic arm is mounted on the mounting seat, thereby enabling adjustment of the robot's height and mounting angle. This facilitates the debugging of the robot according to production needs. For the handling and transfer of parts in the processing of robot components, it can better adjust the initial position of the robot. By rotating the threaded rod, the threaded rod rises and lifts the upper fixed seat to adjust the height. The upper fixed seat drives the limit rod to slide within the limit hole of the lower fixed seat. Then, the fastening nut locks the threaded rod. Rotating the mounting seat adjusts the horizontal angle.
[0018] 2. This robotic arm connecting device allows for adjustment of the mounting base's position by loosening various bolts, raising the pressure plate, disengaging the protrusion at the bottom of the pressure plate from the thrust groove, and rotating the mounting base. Once the mounting base is in the appropriate position, lowering the pressure plate causes the protrusion to insert into the corresponding thrust groove, restricting the rotation of the mounting base. Finally, the bolts in each mounting cylinder are locked to the upper fixed seat. The mounting base has a wide angle adjustment range and small adjustment intervals. Adjusting and locking the mounting base is simple, efficient, and simplifies the debugging process. Attached Figure Description

[0025] A robotic arm connection device, such as Figure 1 and Figure 2 As shown, it includes:
[0026] The lower fixed seat 10 has a liftable upper fixed seat 11 on its top. The upper fixed seat 11 has a horizontally rotatable mounting seat 12 on its top. The mounting seat 12 includes an upper circular plate and a lower circular plate with different diameters. The diameter of the upper circular plate is smaller than that of the lower circular plate. A rotating shaft is fixedly installed at the bottom of the lower circular plate. A shaft hole is opened at the top of the upper fixed seat 11. The rotating shaft is rotatably installed in the shaft hole. A limit rod 16 is fixedly installed at the bottom of the upper fixed seat 11. The limit rod 16 is slidably connected to the lower fixed seat 10. A sleeve 13 is fixedly installed at the top of the lower fixed seat 10. A threaded rod 14 is threadedly connected to the sleeve 13. The threaded rod 14 is rotatably connected to the upper fixed seat 11. A nut 15 for locking is also threadedly connected to the threaded rod 14.
[0027] In this solution, the robotic arm is mounted on the mounting base 12 via a height-adjustable upper fixed base 11 and a horizontally rotatable mounting base 12. This allows for adjustment of the robotic arm's height and mounting angle, facilitating adjustments to the robotic arm according to production needs. For the handling and transfer of parts in the processing of robot components, the initial position of the robotic arm can be better adjusted. By rotating the threaded rod 14, the threaded rod 14 rises and lifts the upper fixed base 11 to adjust the height. The upper fixed base 11 drives the limiting rod 16 to slide within the limiting hole of the lower fixed base 10. Then, the fastening nut 15 is tightened to lock the threaded rod 14. Rotating the mounting base 12 adjusts the horizontal angle.
[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a limiting component is disposed between the mounting base 12 and the upper fixed base 11 to lock the angle of the mounting base 12. The limiting component includes a pressure plate 20, protrusions 21, and thrust grooves 23. The mounting base 12 has several thrust grooves 23. Several protrusions 21 are fixedly installed on the bottom of the pressure plate 20. The protrusions 21 can be inserted into the thrust grooves 23 to limit the rotation of the mounting base 12. The pressure plate 20 is locked to the upper fixed base 11 by bolts. The pressure plate 20 is a rectangular plate, and a circular hole is opened through the center of the top of the pressure plate 20. The circular hole is connected to the mounting base 11. The upper circular plate of the mounting base 12 has a clearance fit, the thrust groove 23 is a semi-circular hole, and several identical thrust grooves 23 are equidistantly arranged on the edge of the lower circular plate of the mounting base 12. The protrusion 21 is a cylinder, and the diameter of the protrusion 21 is equal to the diameter of the thrust groove 23. The limiting component also includes a mounting cylinder 22. A mounting cylinder 22 is fixedly installed at each of the four corners of the bottom of the pressure plate 20. The top of the upper fixed base 11 has threaded holes that correspond one-to-one with the mounting cylinders 22. The bolt passes through the mounting cylinder 22 and connects to the threaded hole to lock and limit the pressure plate 20.
[0029] In this design, to lock the rotatable mounting base 12, the pressure plate 20 is raised by loosening the bolts. The protrusion 21 at the bottom of the pressure plate 20 disengages from the thrust groove 23. Rotating the mounting base 12 adjusts its position. When the mounting base 12 is in the appropriate position, the pressure plate 20 is lowered, and the protrusion 21 inserts into the corresponding thrust groove 23 to restrict the rotation of the mounting base 12. The bolts in each mounting cylinder 22 are then locked to the upper fixed base 11. The mounting base 12 has a wide angle adjustment range and small adjustment intervals. Adjusting and locking the mounting base 12 is simple and efficient.
[0030] The working principle of this utility model is as follows: Rotating the threaded rod 14 raises the upper fixed seat 11 to adjust its height. The upper fixed seat 11 drives the limiting rod 16 to slide within the limiting hole of the lower fixed seat 10. Then, tightening the nut 15 locks the threaded rod 14. Loosening the bolts raises the pressure plate 20, and the protrusion 21 at the bottom of the pressure plate 20 disengages from the thrust groove 23. Rotating the mounting seat 12 adjusts its position. When the mounting seat 12 is in the appropriate position, lowering the pressure plate 20 causes the protrusion 21 to insert into the corresponding thrust groove 23, restricting the rotation of the mounting seat 12. Finally, the bolts in each mounting cylinder 22 are locked to the upper fixed seat 11, thus achieving the adjustment and locking of the robot's height and horizontal angle. For the processing and transfer of robot parts, this method can better adjust the initial position of the robot.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
