[0002] The positioning arm is a mechanical component that is usually used to accurately position and fix a workpiece or tool. It consists of a bracket and a movable arm. The bracket can be installed on machine tools, fixtures and other equipment, and the movable arm can move in multiple directions and position; the main function of the positioning arm is to position and fix the workpiece during machining or assembly, thereby ensuring the accurate position and stability of the workpiece. In the automotive, machinery, aviation and other manufacturing industries, positioning arms are widely used in machine tools, fixtures, testing equipment and other fields, such as for positioning and fixing automotive parts, aircraft engine blades, etc.

[0003] It is found in actual use that this device has the following shortcomings:

[0004] Since the personnel stand on the control console of the positioning arm to control the positioning arm for clamping and fixing, the positioning may be inaccurate due to the line of sight and field of view;

[0005] The grabbing mechanical claws of the existing positioning arms are often used to grab square objects or round objects only, so different positioning arms are needed to grab objects of different shapes, and thus the practical performance is poor.

[0006] Therefore, the present application provides a rotatably adjustable positioning arm to meet the needs. Utility Model Content

[0007] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a rotatable and adjustable positioning arm.

[0008] The technical problem to be solved by the utility model is to provide a rotatably adjustable positioning arm to solve the problems of the existing positioning arms.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] A rotatably adjustable positioning arm comprises:

[0011] A base, which is a mounting base for the novel positioning arm;

[0012] A camera, located above the base;

[0013] a display, which is located above the base;

[0022] A connecting rod, which is arranged through the top of the rotating rod;

[0023] A compass mark, which is wrapped and arranged on the side of the motor;

[0024] The controller is installed through the left surface of the base.

[0025] Preferably, the connecting rod comprises:

[0026] a telescopic arm mounted on the top of the connecting rod;

[0027] A grabber mounted on the front end of the telescopic arm;

[0028] A rotating shaft, which is disposed around the surface of the connecting rod;

[0029] A display is installed on the surface of the rotating shaft.

[0030] Preferably, the grabber comprises:

[0031] A camera is installed through the bottom center of the gripper;

[0032] A dual-axis motor mounted at the inner center of the gripper;

[0033] A threaded rod, which is respectively mounted on the left and right output ends of the dual-axis motor;

[0034] A driving rod, which is threadably connected to the threaded rod through a nut;

[0035] Limiting grooves are respectively provided at the front and rear ends of the left and right sides of the inside of the gripper;

[0036] The limiting rods are installed on the left and right sides of the driving rod and are located in the limiting grooves.

[0037] Preferably, the driving rod comprises:

[0038] triangular fixtures, which are respectively mounted on the bottom of the driving rods;

[0039] The arc grooves are evenly arranged on the inner sides of the triangular fixtures and correspond to the number of the electric cylinders.

[0040] Preferably, the triangular fixture comprises:

[0041] Arc-shaped fixers are evenly arranged inside the triangular fixers and correspond to the number of electric cylinders;

[0042] The push rods all pass through the outer side of the triangular fixer to the inside thereof and are welded to the outer side of the arc-shaped fixer.

[0043] Preferably, the controller is electrically connected to control the display, telescopic arm, electric cylinder, motor, dual-axis motor and camera respectively.

[0044] Compared with the prior art, the utility model has at least the following beneficial effects:

[0045] In the above scheme, by setting up a display and a camera, when a worker stands on the operating table to operate, he only needs to stare at the picture displayed by the camera on the display to quickly and accurately locate and fix the object to be grasped, so that the worker will not be affected by the field of vision and line of sight, resulting in inaccurate positioning and further unstable clamping.

[0046] In the above scheme, by setting a triangular fixer, an electric cylinder and an arc-shaped fixer, after the worker checks the object to be clamped through the display, if it is square, it can be clamped and fixed directly by a dual-axis motor. If it is round, the worker turns on the electric cylinder and pushes the arc-shaped fixer out of the arc-shaped groove, and then uses the dual-axis motor to clamp and fix it. This makes it possible to use one positioning arm to stably clamp square and round objects, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] like Figure 1-4 The utility model provides a rotatable and adjustable positioning arm, which includes a base, which is a mounting base for the positioning arm of the utility model; a camera, which is located above the base; a display, which is located above the base; a compass, which is located above the base; a triangular fixer, which is respectively located on the left and right sides above the base; an electric cylinder, which is evenly arranged on the outside of the triangular fixer; a push rod, which is connected to the output end of the electric cylinder; an arc-shaped fixer, whose outer end is connected to the push rod; by providing the base 1, the positioning arm of the utility model can be installed on the base 1, so that it can be powered on for normal use. At the same time, the base 1 also plays the role of supporting the positioning arm of the utility model. Through the cooperation of the camera 16 and the display 6, the worker only needs to stand in front of the display 6 to operate the positioning arm of the utility model through the picture captured by the camera 16. The positioning arm can achieve the effect of accurate and rapid positioning. At the same time, a azimuth mark 2 is provided, and 36 points are provided on the azimuth mark, that is, there is a 10° difference between each point. At the same time, accurate marks of 90°, 180°, 270°, and 360° are provided at the upper, lower, left, and right corners, so that it is convenient for workers to operate the new model for rotation adjustment, so as to use the positioning arm of the new model more conveniently. At the same time, by providing a triangular fixture 10, the new model can shrink the distance between the triangular fixtures 10 to set square objects into a rhombus or parallelogram structure for fixed clamping. At the same time, if a round object needs to be clamped, the electric cylinder 11 can be activated to drive the push rod 20 to push out the arc fixture 21, so that the arc fixture 21 can fix and clamp the round object, thereby making the practicality of the new model better.

[0055] In this embodiment, Figure 1-2A rotatable and adjustable positioning arm is shown in an embodiment of the utility model, comprising a motor installed on the top of the base; a rotating rod connected to the output end of the motor; a connecting rod penetrating the top of the rotating rod; a azimuth mark wrapped around the side of the motor; and a controller installed through the left surface of the base; by arranging the motor 14 on the top of the base 1, the worker can operate the motor 14 to make the rotating rod 13 connected to the output end of the motor 14 drive the connecting rod 4 connected thereto to rotate. At the same time, the position of the azimuth mark 2 is also specifically described, that is, each time the motor drives the connecting rod 4 to rotate, the worker can accurately check the relationship between the azimuth mark 2 and the connecting rod 4 to accurately adjust the angle. At the same time, the controller 3 is arranged on the base 1, so that the worker can easily operate the new positioning arm.

[0056] In this embodiment, Figure 1-2 A rotatable and adjustable positioning arm is shown in an embodiment of the utility model, comprising a telescopic arm, which is installed on the top of the connecting rod; a gripper, which is installed on the front end of the telescopic arm; a rotating shaft, which is arranged around the surface of the connecting rod; and a display, which is installed on the surface of the rotating shaft. Specifically, the telescopic arm 7 is a device with a telescopic cylinder inside, which can extend or retract the smaller end, which can facilitate the adjustment and use of the present invention and enhance the actual use effect. By arranging the gripper 8 at the front end of the telescopic arm 7, the telescopic function of the telescopic arm 7 can be used at the right time to cooperate with the gripper 8 to position, clamp and fix the objects that need to be positioned, clamped and fixed; and by arranging the rotating shaft 5 on the surface of the connecting rod 4, even if the motor 14 drives the connecting rod 4 to rotate, the worker can rotate the rotating shaft 5 without changing the position of the display 6, which is convenient for the worker to operate and watch.

[0057] In this embodiment, Figure 3A rotatable and adjustable positioning arm provided by an embodiment of the present utility model includes a camera, which is installed through the center of the bottom of the gripper; a biaxial motor, which is installed at the center of the interior of the gripper; threaded rods, which are respectively installed at the left and right output ends of the biaxial motor; driving rods, which are respectively threadedly connected to the threaded rods through nuts; limiting grooves, which are respectively opened at the front and rear ends of the left and right sides inside the gripper; limiting rods, which are installed on the left and right sides of the driving rods and are located in the limiting grooves. Since the camera 16 is installed through the center of the bottom of the gripper 8, workers can accurately position the center straight part of the item to be grabbed, making the positioning effect of the new positioning arm better. And because the limiting rods 19 installed on both sides of the driving rod 9 are located in the limiting grooves 18, when the biaxial motor 15 at the center of the gripper 8 drives the threaded rod 17 to rotate, the driving rod 9 threadedly connected to the threaded rod 17 through the nut will move horizontally left and right on the threaded rod 17. That is, when one side of the threaded rod 17 rotates forward and the other side rotates backward, it will move towards the biaxial motor 15, thereby clamping the grabbed item. And when the forward-rotating side rotates backward and the backward-rotating side rotates forward, it will move in the opposite direction of the biaxial motor 15, thereby loosening the grabbed item and making it fall. At the same time, because the cross-sectional structure of the driving rod 9 is similar to "凢", that is, there is a protrusion in the center, and both ends of the subsequent horizontal part go downward, a nut is arranged at the protrusion and is threadedly connected to the threaded rod 17. Also, it should be noted that because the driving rod 9 will move left and right on the threaded rod 17, four slots are opened at the bottom of the gripper 8 for the driving rod 9 to move through.

[0058] In this embodiment, as Figure 1-2 shown, a rotatable and adjustable positioning arm provided by an embodiment of the present utility model includes triangular fixators, which are respectively installed at the bottom of the driving rods; arc-shaped grooves, which are respectively evenly opened on the inner sides of the triangular fixators and correspond to the number of electric cylinders. Further explanation is that since the triangular fixators 10 are respectively installed at the bottom of the driving rods 9, when the biaxial motor 15 changes, the distance between the two triangular fixators 10 at both ends will also change, thereby resulting in different situations of clamping and loosening. And by opening arc-shaped grooves 12 on the inner sides of the triangular fixators 10, that is, at the positions where the triangles are opened, it enables a movable space for the movement of the arc-shaped fixator 21.

[0059] In this embodiment, as Figure 4A rotatable and adjustable positioning arm is shown in an embodiment of the utility model, comprising arc-shaped fixers, which are evenly arranged inside the triangular fixer and correspond to the number of electric cylinders; push rods, which penetrate the outside of the triangular fixer to the inside thereof and are welded to the outside of the arc-shaped fixer; it is further explained that because the electric cylinder 11 drives the push rod 20 to push inward, the arc-shaped fixer 21 located in the triangular fixer 10 is pushed out, thereby clamping round objects, and when the round objects do not need to be clamped, the electric cylinder 11 drives the push rod to be retracted outward, so that the arc-shaped fixer 21 can be returned to the inside of the triangular fixer 10, thereby clamping and fixing the square objects.

[0060] In this embodiment, Figure 1-4 A rotatable and adjustable positioning arm is shown in an embodiment of the utility model, including a controller electrically connected to control a display, a telescopic arm, an electric cylinder, a motor, a dual-axis motor and a camera; it is further explained that a worker only needs to stand at the controller 3 to conveniently operate the new positioning arm, and the operation method and connection method of the new model are also explained.
