Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a robot joint module assembly positioning device. Background Technology

[0002] As the core component for robot motion execution, the assembly precision of the robot joint module directly determines the robot's motion accuracy, load capacity, and operational stability. As industrial robots develop towards higher precision and higher integration, the requirements for the dimensional and positional tolerances such as coaxiality and parallelism of key components such as reducers, motors, and encoders inside the joint module are becoming increasingly stringent, typically needing to be controlled within the range of 0.01mm-0.05mm.

[0003] Traditional assembly methods rely heavily on manual positioning using general-purpose fixtures. Operators need to repeatedly calibrate the positions of parts based on their experience, resulting in low positioning efficiency and high labor intensity. In addition, general-purpose fixtures have poor adaptability, requiring frequent replacement of fixture components for different models and specifications of joint modules, which makes it difficult to meet the flexible assembly requirements of modern production lines. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a robot joint module assembly and positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A robot joint module assembly and positioning device includes a base plate, with support plates fixedly connected to both ends of the top of the base plate. A rotating rod is rotatably mounted on the top of each of the two support plates. A circular hole adapted to the rotating rod is opened on the top of each of the two support plates. A worktable is fixedly connected between the two rotating rods. A strip frame is fixedly mounted in the middle of the worktable. A strip hole adapted to the strip frame is opened on the worktable. A sliding rod is fixedly connected between the two ends of the inner wall of the strip frame. Strip sliders are slidably mounted on both ends of the sliding rod. A circular hole adapted to the sliding rod is opened in the middle of each of the two strip sliders, and the strip sliders are adapted to the inner wall of the strip frame. A sliding groove is opened on both sides of each strip slider, and a positioning mechanism for positioning the robot is provided on each strip slider.

[0006] Preferably, the positioning mechanism includes a U-shaped slider that is slidably connected to two slide grooves, a clamping plate is fixedly connected to the top of the U-shaped slider, and an arc-shaped rubber pad is fixedly connected to one side of the clamping plate.

[0007] Preferably, the positioning mechanism further includes a U-shaped plate fixedly connected to one side of the U-shaped slider, a rod is slidably sleeved on the U-shaped plate, the rod slidably passes through the U-shaped slider, a round hole adapted to the rod is opened on the U-shaped slider, a pull ring is fixedly connected to the other end of the rod, a baffle is fixedly sleeved inside the U-shaped plate, and a spring is sleeved between the rod and the baffle.

[0008] Preferably, the two strip sliders have multiple insertion holes at equal intervals on the side near the insertion rod, and the insertion holes are adapted to the insertion rod.

[0009] Preferably, both of the two strip sliders are fixedly connected to the bottom of a cam, a cylinder is fixedly connected to one end of the bottom of the worktable, and an L-shaped plate is fixedly connected to the output end of the cylinder. The L-shaped plate has oblique holes on both sides, and each cam is slidably connected in the oblique holes that are close to each other.

[0010] Preferably, a worm gear is fixedly connected to the outer side of one of the rotating rods, and two side plates are fixedly connected to the outer side of the support plate near the worm gear. The two side plates are rotatably connected to the same drive rod.

[0011] Preferably, a worm gear is fixedly sleeved in the middle of the drive rod, and the worm gear meshes with a worm wheel. One end of the drive rod passes through the side plate and is fixedly connected to a crank handle.

[0012] The beneficial effects of this utility model are as follows: By employing positioning mechanisms, strip sliders, sliding rods, and insertion holes, the extension and retraction of cylinders allows two arc-shaped rubber pads to quickly position the robot joint module. Simultaneously, pulling the insertion rod quickly adjusts the initial position of the clamping plate and the arc-shaped rubber pads, facilitating the positioning of joint modules of different sizes. This effectively solves the problems mentioned in the background technology, ensuring the accuracy of robot joint module positioning, reducing positional deviations, and enabling the positioning of robot joint modules of different sizes. This expands the applicability of the device and reduces the cost for enterprises to develop multiple special fixtures for different products. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5 A robot joint module assembly and positioning device includes a base plate 1, with support plates 2 fixedly connected to both ends of the top of the base plate 1. Rotary rods 4 are rotatably fitted onto the top of each support plate 2. Each support plate 2 has a circular hole adapted to the rotary rod 4. A common worktable 3 is fixedly connected between the two rotary rods 4. A strip frame 8 is fixedly fitted into the middle of the worktable 3. A strip hole adapted to the strip frame 8 is formed on the worktable 3. A common sliding rod 803 is fixedly connected between the two ends of the inner wall of the strip frame 8. Both ends are slidably fitted with strip sliders 801. The middle of each strip slider 801 is provided with a round hole that matches the slide rod 803. The strip sliders 801 are adapted to the inner wall of the strip frame 8. Each strip slider 801 has a sliding groove 805 on both sides. Each strip slider 801 is provided with a positioning mechanism 10 for positioning the robot. Through the setting of the positioning mechanism 10, the initial position of the two arc-shaped rubber pads 1007 can be quickly adjusted, which facilitates the rapid positioning of joint modules of different sizes.

[0017] In this utility model, the positioning mechanism 10 includes a U-shaped slider 1001 that is slidably connected to two slide grooves 805. A clamping plate 1006 is fixedly connected to the top of the U-shaped slider 1001, and an arc-shaped rubber pad 1007 is fixedly connected to one side of the clamping plate 1006.

[0018] In this utility model, the positioning mechanism 10 further includes a U-shaped plate 1002 fixedly connected to one side of the U-shaped slider 1001. A rod 1003 is slidably sleeved on the U-shaped plate 1002. The rod 1003 slides through the U-shaped slider 1001. A round hole adapted to the rod 1003 is opened on the U-shaped slider 1001. A pull ring is fixedly connected to the other end of the rod 1003. A baffle 1004 is fixedly sleeved inside the rod 1003 located in the U-shaped plate 1002. A spring 1005 is sleeved between the rod 1003 located in the U-shaped plate 1002 and the baffle 1004.

[0019] In this utility model, two strip sliders 801 are provided with multiple insertion holes 804 at equal distances on the side near the insertion rod 1003, and the insertion holes 804 are adapted to the insertion rod 1003.

[0020] In this utility model, cams 802 are fixedly connected to the bottom of both strip sliders 801, and cylinder 9 is fixedly connected to one end of the bottom of the worktable 3. An L-shaped plate 901 is fixedly connected to the output end of the cylinder 9. Inclined holes 902 are provided on both sides of the L-shaped plate 901. Each cam 802 is slidably connected in the adjacent inclined holes 902. By extending and retracting the cylinder 9, the two strip sliders 801, along with the positioning mechanism 10, can be controlled to move closer and further apart.

[0021] In this utility model, a worm gear 5 is fixedly connected to the outer side of one of the rotating rods 4, and two side plates 6 are fixedly connected to the outer side of the support plate 2 near the worm gear 5. The two side plates 6 are rotatably connected to the same drive rod 601.

[0022] In this utility model, a worm gear 7 is fixedly sleeved in the middle of the drive rod 601, and the worm gear 7 meshes with the worm wheel 5. One end of the drive rod 601 passes through the side plate 6 and is fixedly connected to a crank handle 602. By rotating the crank handle 602, the angle between the worktable 3 and the horizontal plane can be adjusted, which is convenient for users to use.

[0023] Working principle: When in use, rotating the crank handle 602 forward and backward causes the worm gear 7 to drive the worm wheel 5 to rotate, which in turn causes the rotating rod 4 to rotate with the worktable 3, thereby adjusting the angle of the worktable 3 for better robot positioning. The robot joint module to be positioned is placed between two arc-shaped rubber pads 1007. The cylinder 9 is then activated to retract, causing the two cams 802 to slide in the inclined holes 902, bringing the two strip sliders 801 closer together, thus aligning the two arc-shaped rubber pads 1007 with the robot. The human joint module is clamped and positioned. When positioning joint modules of different sizes is required, the initial position of the two arc-shaped rubber pads 1007 can be adjusted, and the insertion rod 1003 can be pulled to compress the spring 1005. At this time, the insertion rod 1003 separates from the insertion hole 804. Then, the U-shaped slider 1001 can be slid left and right to adjust to the appropriate position. After that, the insertion rod 1003 is released. Under the action of the spring 1005, the insertion rod 1003 can be inserted into the corresponding insertion hole 804 to achieve fixation. In this way, it can be put into work quickly.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
