[0022] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0023] The following describes a quick-adjusting multi-directional clamping arm according to an embodiment of the present invention in detail with reference to the accompanying drawings.

[0024] Example

[0025] For easier understanding, please refer to Figures 1 to 4 This utility model provides an embodiment of a quick-adjusting multi-directional clamping arm, including a base plate 1, on which an auxiliary fixing mechanism is provided; the auxiliary fixing mechanism includes a mounting frame 2, a rotating component 3, several threaded holes 5, a locking screw 6, a fixing pad 7, an electric push rod 9, a moving block 10, a connecting rod 11, and a mounting block 12. The mounting frame 2 is fixedly installed on one side of the base plate 1, the rotating component 3 is rotatably installed on the mounting frame 2, several threaded holes 5 are opened on the outer wall of the rotating component 3, the locking screw 6 is threadedly connected to the inner wall of the threaded holes 5, the fixing pad 7 is fixedly installed on one end of the locking screw 6, the mounting block 12 is fixedly installed on the outer wall of the rotating component 3, the electric push rod 9 is fixedly installed on the bottom of the inner wall of the mounting frame 2, the moving block 10 is fixedly installed on the output end of the electric push rod 9, the connecting rod 11 is rotatably installed on one side of the moving block 10, and the other end of the connecting rod 11 is rotatably installed on one side of the mounting block 12.

[0026] It should be noted that by setting an auxiliary fixing mechanism, the electric push rod 9 drives the rotating part 3 to move back and forth, which can adjust the fixing position of the fixing pad 7 on the workpiece. After the workpiece is fixed on the base plate 1 by the pressure plate 17, the rotating part 3 rotates to adjust the position of the fixing pad 7, and the fixing pad 7 clamps the workpiece to perform multi-angle auxiliary fixing, which can increase the stability of the workpiece clamping and make the workpiece better weldable.

[0027] In this example, the mounting frame 2 is fixedly installed on one side of the base plate 1 by bolts. The output end of the electric push rod 9 extends and retracts, driving the connecting rod 11 to pull or push the mounting block 12, which can drive the rotating part 3 to reciprocate and rotate at a certain angle.

[0028] In this example, the worker manually turns the locking screw 6, which moves the fixing pad 7, allowing the fixing pad 7 to be clamped on the surface of the workpiece, thus providing auxiliary fixation for irregularly shaped workpieces such as irregularly shaped steel plates and irregularly shaped bearings.

[0029] In some embodiments, such as Figure 2 , Figure 3 As shown, a rotating hole is provided on one side of the mounting frame 2, and the rotating component 3 is rotatably installed on the inner wall of the rotating hole. Several annular grooves are provided on the outer wall of the rotating component 3. Several limiting components 4 are fixedly installed on the inner wall of the mounting frame 2. One end of the limiting component 4 extends into the corresponding annular groove. A first slide rail 8 is fixedly installed on one side of the inner wall of the mounting frame 2, and the moving block 10 is slidably installed on the first slide rail 8.

[0030] It should be noted that the rotating part 3 is ring-shaped, with one end of the rotating part 3 extending into the interior of the mounting frame 2. The limiting part 4 is fixed to the corresponding position on the inner wall of the mounting frame 2 by screws, thereby installing and limiting the rotating part 3.

[0031] In this example, the moving block 10 is limited by setting the first slide rail 8, so that the moving block 10 moves up and down along the first slide rail 8.

[0032] In this example, the rotating component 3 is driven to rotate by the transmission structure of the electric push rod 9 and the connecting rod 11, making the angle adjustment of the rotating component 3 more flexible.

[0033] In some embodiments, such as Figure 4 As shown, a mounting plate 13 is fixedly installed on one side of the top of the base plate 1, a movable frame 14 is fixedly installed on one side of the mounting plate 13, a hydraulic cylinder 16 is fixedly installed on the top of the movable frame 14, the output end of the hydraulic cylinder 16 extends into the interior of the movable frame 14, and a pressure plate 17 is fixedly installed on the output end of the hydraulic cylinder 16.

[0034] It should be noted that the hydraulic cylinder 16 drives the pressure plate 17 to move up and down, and the pressure plate 17 fixes the workpiece on the top of the base plate 1. A pressure sensor can be set on the pressing end face of the pressure plate 17. The pressure sensor is controlled by the control board in the prior art. The control board also controls the hydraulic cylinder 16, so that the pressure plate 17 presses the workpiece with appropriate force.

[0035] In some embodiments, such as Figure 4 As shown, the movable frame 14 is fixedly installed with second slide rails 15 on both sides, and one side of the second slide rail 15 extends into the interior of the movable frame 14. The pressure plate 17 is slidably installed on the second slide rail 15.

[0036] It should be noted that by setting the second slide rail 15, the pressure plate 17 is limited when it moves up and down.

[0037] In this utility model, the electric push rod 9 and the hydraulic cylinder 16 are known components and will not be described in detail here.

[0038] Working principle: When pressing the workpiece, the hydraulic cylinder 16 drives the pressure plate 17 to move up and down, and the pressure plate 17 fixes the workpiece on the top of the base plate 1. A pressure sensor can be set on the pressing end face of the pressure plate 17. The pressure sensor is controlled by the control board in the prior art. The control board controls the hydraulic cylinder 16 and adjusts the pressing force of the pressure plate 17.

[0039] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
