Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arms, in particular to a teaching-type multifunctional six-axis mechanical arm. Background Art

[0002] Robotic arms are commonly used in handling, welding, grinding, assembly, palletizing, etc. in the industrial production process. The axis of a robotic arm refers to the number of active joints of the robot. A six-axis robotic arm refers to a robotic arm with six active joints. The teaching-type multifunctional teaching six-axis robotic arm is mainly used in teaching scenarios, especially in the machinery industry. It can enable students to have a clearer understanding of the operation mode and operation procedures of the robotic arm.

[0003] The existing teaching-type multifunctional teaching six-axis robotic arms are usually installed in specific classrooms of training institutions or colleges and operated by teachers and students. Some students are prone to safety accidents due to their lack of proficiency in operation and programming errors. Especially in teaching scenarios, some students may watch closely to better understand. Students' erroneous operations or incorrect programming can easily cause the robotic arm to collide with other students, resulting in poor safety. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a teaching-type multifunctional teaching six-axis robotic arm to solve the technical problem of poor safety.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a teaching-type multifunctional teaching six-axis robotic arm, comprising a base, a motor is installed inside the base, and a first bevel gear is connected to the output end of the motor, a double bevel gear shaft is connected inside the base, a guide rod and a screw rod are respectively arranged on the top of the base, and a second bevel gear is connected to the bottom end of the screw rod; one side of the guide rod and the screw rod are connected to a bracket, and one side of the bracket is connected to a first baffle, and the inner ring of the first baffle is connected to the second baffle.

[0006] By adopting the above technical solution, the first baffle is raised by the cooperation of the screw rod and the guide rod. After the first baffle is raised, one side thereof abuts against the second baffle, so that the first baffle pulls the second baffle upward, thereby preventing the student from getting close and causing the robot arm to injure the student. Moreover, the first baffle and the second baffle are both made of acrylic material with good light transmittance for easy observation by the student. When the operation is completed, the screw rod and the guide rod cooperate to move the first baffle downward. The downward movement of the first baffle causes the second baffle to move downward under the influence of gravity and contact the ground, while the first baffle can continue to move downward and contact the ground, and the telescopic structure reduces the volume.

[0007] Furthermore, the first baffle plate and the second baffle plate are both made of acrylic material, and the second baffle plate is slidably connected to the first baffle plate.

[0008] By adopting the above technical solution, the first baffle and the second baffle are both made of acrylic material with good light transmittance, which is convenient for students to observe. The screw rod and the guide rod cooperate to move the first baffle downward. The downward movement of the first baffle causes the second baffle to move downward under the influence of gravity and contact the ground, while the first baffle can continue to move downward and contact the ground, and the telescopic structure reduces the volume.

[0009] Furthermore, the cross section of the first baffle is in an "L" shape, and the cross section of the second baffle is in a " " shape.

[0010] By adopting the above technical solution, one side of the first baffle plate rises and contacts with the second baffle plate, so that the first baffle plate pulls the second baffle plate upward, thereby preventing the student from getting close and causing the six-axis robot arm to hit the student.

[0011] Furthermore, the first baffle and the second baffle are both in annular shape.

[0012] By adopting the above technical solution, the outer periphery of the base is shielded by the first baffle and the second baffle, so as to prevent the phenomenon that the trainees are hit by the main body of the six-axis robot arm due to the trainees getting close.

[0013] Furthermore, the guide rod, the lead screw, the double-bevel gear shaft and the second bevel gear are each provided in four numbers, and the bracket is provided in eight numbers.

[0014] By adopting the above technical solution, after the motor is started, the output end drives the first bevel gear to rotate, the first bevel gear drives the four double-bevel gear shafts to rotate, and the four lead screws rotate synchronously through the engagement of the second bevel gear and the double-bevel gear shaft.

[0015] Furthermore, four of the brackets are slidably connected to the guide rod, and another four brackets are threadedly connected to the lead screw.

[0016] By adopting the above technical solution, after the four screw rods rotate synchronously, the screw rods cooperate with the guide rods to displace the bracket, thereby causing the bracket to drive the first baffle to displace.

[0017] Furthermore, a six-axis robotic arm body is installed in the middle of the top of the base, and a robotic arm end is arranged on one side of the six-axis robotic arm body.

[0018] By adopting the above technical solution, students can install the tools that come with the robot arm, such as clamps, welding guns, grinders and other tools at the end of the robot arm. After that, students can place the workpiece to be processed or transported on the top of the base, or install the clamp on the base and then place the workpiece into the clamp. When ready, students start the six-axis robot arm body and motor. After the six-axis robot arm body is started, it cooperates with the tools at the end of the robot arm to transport or process the workpiece.

[0019] Furthermore, a mounting hole is provided on one side of the first baffle plate, and a hexagon socket bolt is connected inside the mounting hole, and the first baffle plate is detachably connected to the bracket through the hexagon socket bolt.

[0020] By adopting the above technical solution, when the first baffle or the second baffle is damaged and needs to be replaced, the trainee can remove the hexagon socket bolt from the mounting hole, thereby disassembling the first baffle and the second baffle. The trainee then places the new second baffle into the inner circle of the new first baffle, and then fits the first baffle to the bracket and screws in the hexagon socket bolt to complete the assembly.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] 1. The utility model is provided with a first baffle, a second baffle, a guide rod, a screw rod and a bracket. The screw rod and the guide rod cooperate to make the first baffle rise. After the first baffle rises, one side of the first baffle abuts against the second baffle, so that the first baffle pulls the second baffle to move up, thereby preventing the student from approaching and causing the mechanical arm to hit the student. The first baffle and the second baffle are both made of acrylic material, which has good light transmittance and is convenient for the student to observe. When the operation is completed, the screw rod and the guide rod cooperate to move the first baffle down. The first baffle moves down so that the second baffle moves down and contacts the ground under the influence of gravity, while the first baffle can continue to move down and contact the ground. The telescopic structure reduces the volume. It effectively prevents the student from approaching and causing collision when the mechanical arm is working, thereby improving safety.

[0023] 2. The utility model arranges the first bevel gear, the double-bevel gear shaft and the second bevel gear. After the motor is started, the output end drives the first bevel gear to rotate, and the first bevel gear drives the four double-bevel gear shafts to rotate. The second bevel gear is meshed with the double-bevel gear shaft to make the four screw rods rotate synchronously, so that the first baffle is evenly stressed and displaced, thereby avoiding structural deflection and increasing structural stability.

[0033] A first baffle plate 4 is connected to one side of the bracket 8, and a second baffle plate 5 is connected to the inner circle of the first baffle plate 4. Both the first baffle plate 4 and the second baffle plate 5 are made of acrylic material with good light transmittance for easy observation by students. The second baffle plate 5 is slidably connected to the first baffle plate 4, the cross-section of the first baffle plate 4 is in an "L" shape, and the cross-section of the second baffle plate 5 is in a "7" shape. Both the first baffle plate 4 and the second baffle plate 5 are in a circular shape, and the first baffle plate 4 is raised by the cooperation of the screw rod 7 and the guide rod 6. After the first baffle plate 4 rises, one side thereof abuts against the second baffle plate 5, so that the first baffle plate 4 pulls the second baffle plate 5 upward to prevent students from getting close and injuring the six-axis robot arm body 2.

[0034] See also Figure 1-Figure 3In the above embodiment, a six-axis robot arm body 2 is installed in the middle of the top of the base 1, and a robot arm end 3 is arranged on one side of the six-axis robot arm body 2. Trainees can install the tools matching the robot arm, such as clamps, welding guns, grinders and other tools on the robot arm end 3. After that, trainees can place the workpiece to be processed or transported on the top of the base 1, or install a clamp on the base 1 and then put the workpiece into the clamp. When ready, the trainees turn on the six-axis robot arm body 2 and the motor 9. After the six-axis robot arm body 2 is started, it cooperates with the tools at the robot arm end 3 to transport or process the workpiece.

[0035] Embodiment 2:

[0036] On the basis of the above-mentioned embodiment 1, although the first baffle 4 and the second baffle 5 are provided to effectively avoid collision caused by students approaching the robot arm when it is working, thereby improving safety; however, the first baffle 4 and the second baffle 5 are difficult to replace due to aging and damage after being used for too long; now, by providing the hexagon socket bolt 14, the first baffle 4 and the second baffle 5 can be easily replaced.

[0037] See also Figure 3 and Figure 4 In the above embodiment, a mounting hole 13 is opened on one side of the first baffle plate 4, and a hexagon socket bolt 14 is connected inside the mounting hole 13. The first baffle plate 4 is detachably connected to the bracket 8 through the hexagon socket bolt 14. When the first baffle plate 4 or the second baffle plate 5 is damaged and needs to be replaced, the trainee can remove the hexagon socket bolt 14 from the mounting hole 13, so that the first baffle plate 4 and the second baffle plate 5 can be disassembled. Then the trainee puts the new second baffle plate 5 into the inner circle of the new first baffle plate 4, and then the trainee fits the first baffle plate 4 with the bracket 8 and screws in the hexagon socket bolt 14 to complete the assembly work.

[0038] The implementation principle of the utility model is as follows: first, the trainee can install the tools matching the robot arm, such as the clamp, welding gun, grinder and other tools, on the end 3 of the robot arm, and then the trainee can place the workpiece to be processed or transported on the top of the base 1, or install the clamp on the base 1 and then put the workpiece into the clamp. After preparation, the trainee turns on the six-axis robot arm body 2 and the motor 9. After the six-axis robot arm body 2 is started, it cooperates with the tools at the end 3 of the robot arm to transport or process the workpiece;

[0039] After the motor 9 is started, the output end drives the first bevel gear 10 to rotate, and the first bevel gear 10 drives the four double-bevel gear shafts 11 to rotate. The second bevel gear 12 is meshed with the double-bevel gear shaft 11 to make the four screw rods 7 rotate synchronously. At this time, the first baffle 4 is raised by the cooperation of the screw rod 7 and the guide rod 6. After the first baffle 4 rises, one side of the first baffle 4 abuts against the second baffle 5, so that the first baffle 4 pulls the second baffle 5 to move up, avoiding the phenomenon that the trainee approaches and causes the six-axis robot arm body 2 to hit the trainee. The first baffle 4 and the second baffle 5 are both made of acrylic material, which has good light transmittance and is convenient for the trainee to observe. Then the trainee turns off the motor 9;

[0040] When the operation is finished, the trainee turns on the motor 9 again to reverse the output end of the motor 9. At this time, the screw rod 7 cooperates with the guide rod 6 to move the first baffle 4 downward. The downward movement of the first baffle 4 causes the second baffle 5 to move downward under the influence of gravity and contact the ground. The first baffle 4 can continue to move downward and contact the ground, and the telescopic structure reduces its volume.

[0041] When the first baffle 4 or the second baffle 5 is damaged and needs to be replaced, the trainee can remove the hexagon socket bolt 14 from the mounting hole 13, so that the first baffle 4 and the second baffle 5 can be disassembled. Then the trainee puts the new second baffle 5 into the inner circle of the new first baffle 4, and then the trainee fits the first baffle 4 with the bracket 8 and screws in the hexagon socket bolt 14 to complete the assembly.
