Description

Technical Field

[0001] The utility model belongs to the technical field of welding robots, and particularly relates to a robot welding positioning device. Background Art

[0002] Industrial robots are automated machines specially designed to perform various manufacturing tasks. They are usually composed of robotic arms, sensors, control systems and terminal actuators. They can perform tasks according to pre-programmed instructions or sensor feedback. They have a wide range of applications, can improve production efficiency, reduce costs, and replace manual operations in dangerous environments. They are usually used in automated production lines to perform tasks with high repetitiveness and high precision requirements. For example, in the welding industry, compared with workers, industrial robots can more accurately control the speed, position and force of welding, ensuring stable and consistent welding quality. In addition, industrial robots can work normally in harsh environments. Operators only need to monitor the welding situation in real time through sensors to achieve stable welding, which greatly liberates the labor intensity of workers. At the same time, because industrial robots rely on the flexible changes of robotic arms and joints, they can complete relatively complex and irregular and linkage welding tasks between multiple objects, so devices are required to position and fix these objects.

[0003] In existing positioning and fixing devices, objects are often clamped and fixed by means of bolts and pressing plates. However, this method cannot fix multiple materials and cannot accommodate irregular placement of multiple objects. Utility Model Content

[0006] In the above technical solution, further, the fixing assembly includes a fixing screw body arranged inside the positioning hole, and the upper and lower ends of the fixing screw body close to the positioning platform are respectively screwed with nut 2 and nut 1, and the nut 2 and nut 1 are both against the positioning platform, the top of the nut 1 is fixedly connected to a connecting block, the top of the connecting block is fixedly connected to a fixed shaft, the top of the fixed shaft is inserted and rotatably connected to a rotating block, the top of the rotating block is fixedly connected to two guide rails distributed in opposite directions, and both ends of the guide rails are slidably connected with movable blocks, and the two movable blocks are respectively fixedly connected with clamp 1 and clamp 2 on the sides away from each other, and a block screw is screwed and inserted between the two movable blocks.

[0007] In the above technical solution, further, the clamp 2 includes a clamping piece 1 fixedly connected to one side of the movable block, one side of the clamping piece 1 is inserted and rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is inserted and fixedly connected to a clamping piece 2.

[0008] In the above technical solution, further, the outer wall of the rotating block is fixedly connected with L-shaped rods distributed in opposite directions, and the bottom of the L-shaped rod and the side away from the rotating block are respectively fixedly connected with a movable plate and a C-shaped rod, the outer shape of the movable plate is arc-shaped, and the bottom of the C-shaped rod is inserted and slidably connected with a clamping part.

[0009] In the above technical solution, further, the clamped part includes a clamped block, a guide rod and a shift block connected in sequence from top to bottom, and also includes friction-increasing blocks that are sleeved and fixedly connected to the outside of the clamped block and evenly distributed, and the guide rod is inserted and slidably connected to the C-shaped rod.

[0010] In the above technical solution, further, a movable groove 1 and a movable groove 2 are respectively provided on the upper and lower sides of the connecting block, and the shapes of the movable groove 1 and the movable groove 2 are respectively adapted to the shapes of the movable piece and the clamped block.

[0012] In the above technical solution, further, the positioning platform is C-shaped, and a movable hole is opened at the bottom of the positioning platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] During installation, nut 2 is pre-threaded on the fixed screw body, and nut 2 is turned to adjust the part of the fixed screw body located on the positioning platform plane, thereby adjusting the fixed height of the material. After reaching the specified height, the staff uses nut 1 to fix it from the bottom, and cooperates with nut 2 to fix the fixed screw body as a whole. Turn the rotating block and twist the block screw to move the movable block along the guide rail, so that clamp 1 or clamp 2 is tightly against the object. During the process, clamp 1 and clamp 2 can be selected according to the shape of the object to make the fixing effect better. In this way, multiple components can be fixed through positioning. The holes are fixed to a specified distance as needed, so that multiple, irregularly arranged and multi-shaped materials can be fixed separately. This design makes it more flexible to grasp the position of the fixed material, and at the same time, the clamp can be selected according to the shape, which makes it more adaptable. When the second pressing piece and the first pressing piece are parallel, they can offset the plane of the object, pushing the second pressing piece to drive the rotating shaft to rotate inside the first pressing piece, thereby forming an angle. This design can form an angle to better limit and fix the junction of the two surfaces of the square object, and the angle can be adjusted, which is highly practical.

[0015] The clamped block is in contact with the C-shaped rod. During the rotation process, the rotating block drives the L-shaped rod to rotate synchronously, and then drives the movable piece and the C-shaped rod to rotate synchronously. The movable piece rotates inside the movable groove one, thereby increasing the guiding force during the rotation of the rotating block, making the rotation of the rotating block more stable and less prone to tilting and shaking. At the same time, the inner wall of the C-shaped rod fits with the outer wall of the connecting block, which further improves the stability of the rotation of the rotating block. After reaching the appropriate position, the shift block is pushed upward to make the guide rod drive the clamped block to move upward and be stuck into the inside of the movable groove two, squeezing the deformation belt to deform the deformation belt. At the same time, the friction block increases the friction to prevent deviation. Through such a design, the locking ability of the rotating block is enhanced, and the material can be clamped more stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-6 A robot welding positioning device shown includes a positioning platform 1, the outer wall of the positioning platform 1 is provided with evenly distributed positioning holes 2, the shape of the positioning platform 1 is C-shaped, the bottom of the positioning platform 1 is provided with a movable hole 4, and the four corners of the bottom of the positioning platform 1 are fixedly connected to support legs 3 by bolts.

[0025] In the above setting, by setting the positioning platform 1 into a C shape, compared with the traditional direct connection with the support leg 3, combined with the movable hole 4, while reducing the cost, there is sufficient activity space under the positioning platform 1, which makes it more convenient for staff to operate under the positioning platform 1, thereby optimizing the overall user experience.

[0026] The outer wall of the positioning platform 1 is fixedly connected with a fixing component, which is used to cooperate with the positioning hole 2 to position and fix multiple objects. The fixing component is connected to the positioning platform 1, and the fixing component includes a fixing screw 5 arranged inside the positioning hole 2. The upper and lower ends of the fixing screw 5 close to the positioning platform 1 are respectively screwed with nut 2 7 and nut 1 6, and nut 2 7 and nut 1 6 are both against the positioning platform 1. The top of nut 1 6 is fixedly connected with a connecting block 8, and the top of the connecting block 8 is fixedly connected with a fixed shaft 19. The top of the fixed shaft 19 is inserted and rotatably connected with a rotating block 9. The top of the rotating block 9 is fixedly connected with two guide rails 10 distributed in opposite directions. Both ends of the guide rail 10 are slidably connected with movable blocks 11. The two movable blocks 11 are fixedly connected with a clamp 12 and a clamp 2 13 on the side away from each other. A screw with a block 14 is screwed and inserted between the two movable blocks 11.

[0027] When the material is fixed to the specified height, the staff uses nut 1 6 to fix it from the bottom, and cooperates with nut 2 7 to fix the fixed screw 5 as a whole. The rotating block 9 is rotated and the block screw 14 is twisted to move the movable block 11 along the guide rail 10, so that the clamp 1 12 or the clamp 2 13 is tightly against the object. During the process, the clamp 12 and the clamp 2 13 can be selected according to the shape of the object to achieve a better fixing effect. In this way, multiple components are fixed to the specified distance through the positioning hole 2 as needed, so that multiple and irregularly arranged and multi-shaped materials can be fixed separately. Such a design makes it more flexible to grasp the position of the fixed material, and at the same time, the clamp can be selected according to the shape to achieve greater adaptability.

[0028] The second clamp 13 includes a first pressing piece 16 fixedly connected to one side of the movable block 11 , a rotating shaft 18 is inserted into and rotatably connected to one side of the first pressing piece 16 , and a second pressing piece 17 is inserted into and fixedly connected to the outer wall of the rotating shaft 18 .

[0029] In the above setting, when the pressing piece 2 17 and the pressing piece 1 16 are parallel, they can offset the plane of the object, pushing the pressing piece 2 17 to drive the rotating shaft 18 to rotate inside the pressing piece 1 16, thereby forming an angle. Through such a design, the angle can be formed to better limit and fix the junction of the two surfaces of the square object, and the angle can be adjusted, which is highly practical.

[0030] The outer wall of the rotating block 9 is fixedly connected with an L-shaped rod 20 distributed in opposite directions, and the bottom of the L-shaped rod 20 and the side away from the rotating block 9 are respectively fixedly connected with a movable piece 22 and a C-shaped rod 21. The movable piece 22 has an arc-shaped shape, and the bottom of the C-shaped rod 21 is inserted and slidably connected with a clamped part. The clamped part includes a clamped block 24, a guide rod 25 and a shift block 23 connected in sequence from top to bottom, and also includes friction-increasing blocks 26 that are sleeved and fixedly connected to the outside of the clamped block 24 and evenly distributed. The guide rod 25 is inserted and slidably connected to the C-shaped rod 21. A movable groove 15 and a movable groove 27 are respectively provided on the upper and lower sides of the connecting block 8, and the shapes of the movable groove 15 and the movable groove 27 are respectively adapted to the shapes of the movable piece 22 and the clamped block 24. A deformation belt 28 is fixedly connected on both sides of the inner wall of the movable groove 27, and the deformation belt 28 is against the friction-increasing block 26.

[0031] In the above setting, the clamped block 24 is in contact with the C-shaped rod 21. During the rotation, the rotating block 9 drives the L-shaped rod 20 to rotate synchronously, and then drives the movable piece 22 and the C-shaped rod 21 to rotate synchronously. The movable piece 22 rotates inside the movable groove 15, which increases the guiding force during the rotation of the rotating block 9, making the rotation of the rotating block 9 more stable and less prone to tilting and shaking. At the same time, the inner wall of the C-shaped rod 21 fits with the outer wall of the connecting block 8, which further improves the rotation stability of the rotating block 9. After reaching the appropriate position, the shift block 23 is shifted upward to make the guide rod 25 drive the clamped block 24 to move upward and get into the inside of the movable groove 27, squeezing the deformation belt 28 to deform the deformation belt 28. At the same time, the friction-increasing block 26 increases the friction to prevent deviation. Through such a design, the locking ability of the rotating block 9 is enhanced, and the material can be clamped more stably.

[0032] Working principle:

[0033] By setting the positioning platform 1 into a C shape, compared with the traditional direct connection with the support legs 3, combined with the movable holes 4, while reducing the cost, sufficient space for movement is provided under the positioning platform 1, making it more convenient for workers to operate under the positioning platform 1, thereby optimizing the overall user experience;

[0034] During installation, nut 2 7 is pre-screwed on the fixed screw body 5, and nut 2 7 is rotated to adjust the part of the fixed screw body 5 located on the plane of the positioning platform 1, thereby adjusting the fixed height of the material. After reaching the specified height, the staff uses nut 1 6 to fix it from below, and cooperates with nut 2 7 to fix the fixed screw body 5 as a whole, rotates the rotating block 9 and twists the belt screw 14 to make the movable block 11 move along the guide rail 10, so that the clamp 1 12 or the clamp 2 13 is tightly against the object. During the process, the clamp 1 12 and the clamp 2 13 can be selected according to the shape of the object to achieve a better fixing effect. In this way, multiple components are fixed to the specified distance through the positioning holes 2 as needed, so that multiple and irregularly arranged and multi-shaped materials can be fixed separately. Through such a design, the position of the fixed material can be grasped more flexibly, and the clamp can be selected according to the shape, thereby having greater adaptability.

[0035] When the second pressing piece 17 and the first pressing piece 16 are parallel, they can counteract the plane of the object, pushing the second pressing piece 17 to drive the rotating shaft 18 to rotate inside the first pressing piece 16, thereby forming an angle. This design can form an angle to better limit and fix the junction of the two surfaces of the square object, and the angle can be adjusted, which is highly practical.

[0036] The clamped block 24 is in contact with the C-shaped rod 21. During the rotation, the rotating block 9 drives the L-shaped rod 20 to rotate synchronously, and then drives the movable piece 22 and the C-shaped rod 21 to rotate synchronously. The movable piece 22 rotates inside the movable groove 15, which increases the guiding force during the rotation of the rotating block 9, making the rotation of the rotating block 9 more stable and less prone to tilting and shaking. At the same time, the inner wall of the C-shaped rod 21 fits with the outer wall of the connecting block 8, which further improves the rotation stability of the rotating block 9. After reaching the appropriate position, the shift block 23 is shifted upward to make the guide rod 25 drive the clamped block 24 to move upward and get into the inside of the movable groove 27, squeezing the deformation belt 28 to deform the deformation belt 28. At the same time, the friction-increasing block 26 increases the friction to prevent deviation. Through such a design, the locking ability of the rotating block 9 is enhanced, and the material can be clamped more stably.
