Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to an engineering robot manipulator. Background Technology

[0002] An engineering robot is an intelligent machine capable of semi-autonomous or fully autonomous operation. Robots can perform tasks such as working or moving through programming and automatic control, while a robotic arm is an automated manipulator used to grasp, move objects, or operate tools according to a fixed program.

[0003] To improve applicability, existing robotic arms are usually designed with adjustable height and length, such as the Chinese utility model patent with publication number CN219027506U, which discloses a robotic arm.

[0004] However, in actual use, it has been found that the robotic arm used in the above-mentioned robots can only adjust the height and length, and it is difficult to adjust the joint angle according to the task requirements. This results in the robotic arm being able to perform operations in a single direction or along a fixed path, making it difficult to cope with complex spatial requirements. Utility Model Content

[0005] The purpose of this invention is to provide an engineering robot manipulator that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engineering robot manipulator, comprising a base plate, a rotating assembly, a lifting hydraulic cylinder, an angle adjusting assembly, and a distance adjusting hydraulic cylinder. The rotating assembly is disposed above the base plate, the lifting hydraulic cylinder is vertically disposed above the rotating assembly, the angle adjusting assembly is disposed at the output end of the lifting hydraulic cylinder, and the distance adjusting hydraulic cylinder is horizontally disposed on the angle adjusting assembly. A clamping assembly is disposed at the output end of the distance adjusting hydraulic cylinder. The rotating assembly drives the lifting hydraulic cylinder, the angle adjusting assembly, the distance adjusting hydraulic cylinder, and the clamping assembly to rotate, changing the clamping direction. The lifting hydraulic cylinder is used to adjust the clamping height. The length hydraulic cylinder adjusts the angle through the angle adjusting assembly, thereby adjusting the angle of the clamping assembly to change the clamping angle distance. The distance adjusting hydraulic cylinder is used to adjust the distance between the clamping assembly and the object to be clamped.

[0007] In a preferred embodiment of this invention, the rotating assembly includes a U-shaped frame, a rotary motor, and a turntable. The U-shaped frame is fixed above the base plate, the turntable is rotatably connected above the U-shaped frame, the rotary motor is fixed inside the U-shaped frame, and the drive shaft of the rotary motor is connected to the center of the turntable. The bottom of the lifting hydraulic cylinder is fixed above the turntable. The rotary motor drives the turntable to rotate, which in turn drives the lifting hydraulic cylinder to rotate, thereby causing the angle adjustment assembly, the distance adjustment hydraulic cylinder, and the clamping assembly to rotate.

[0008] In a preferred embodiment of this invention, the angle adjustment assembly includes a mounting base, a first hinge base, a first connecting shaft, a second hinge base, a second connecting shaft, an angle adjustment hydraulic cylinder, a third hinge base, and a connecting block. The mounting base is fixed to the output end of the lifting hydraulic cylinder. The first hinge base is fixed above the mounting base. The first connecting shaft is hinged to the inner side of the first hinge base. The distance adjustment hydraulic cylinder is fixed to the first connecting shaft. The second hinge base is fixed to the side of the mounting base. The second connecting shaft is hinged to the inner side of the second hinge base. The angle adjustment hydraulic cylinder is fixed to the second connecting shaft. The third hinge base is fixed to the output end of the angle adjustment hydraulic cylinder. The connecting block is hinged to the inner side of the third hinge base and fixed to the side of the distance adjustment hydraulic cylinder. The angle adjustment hydraulic cylinder outputs, causing the angle adjustment hydraulic rod to push the distance adjustment hydraulic cylinder, resulting in the distance adjustment hydraulic cylinder tilting. During this process, the first connecting shaft rotates within the first hinge base, the second connecting shaft rotates within the second hinge base, and the connecting block rotates within the third hinge base.

[0009] In a preferred embodiment of this invention, the clamping assembly includes a slide rail, a bidirectional lead screw, lead screw sliders, a drive motor, and clamping plates. The slide rail is fixed to the output end of the distance-adjusting hydraulic cylinder. The bidirectional lead screw is rotatably connected to the inner side of the slide rail. Two lead screw sliders are symmetrically threaded onto the bidirectional lead screw, and a clamping plate is fixed to each lead screw slider. The drive motor is fixed to the end of the slide rail, and the drive shaft of the drive motor is connected to the bidirectional lead screw. The drive motor drives the bidirectional lead screw to rotate, thereby driving the two lead screw sliders to move relative to each other. When the two lead screw sliders approach each other, they will cause the clamping plates to clamp the object.

[0010] In a preferred embodiment of this invention, the lead screw and slider are fitted against the inner wall of the slide rail, and a sliding connection is used between the lead screw and slider and the slide rail. This restricts the movement of the lead screw and slider, improving the stability of their movement.

[0011] As a preferred embodiment of this invention, the clamping plate is provided with a pad, which is a rubber pad. The rubber pad primarily prevents hard contact between the clamping plate and the object being clamped, and improves the anti-slip effect.

[0012] The rotary motor, lifting hydraulic cylinder, angle adjusting hydraulic cylinder, distance adjusting hydraulic cylinder, and drive motor are all connected and controlled through the overall control system. The rotary motor is a servo motor, the lifting hydraulic cylinder is a single-piston rod hydraulic cylinder, the angle adjusting hydraulic cylinder is a small double-acting hydraulic cylinder, the distance adjusting hydraulic cylinder is a single-piston rod hydraulic cylinder, and the drive motor is a stepper motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention allows for multi-dimensional adjustments in rotation, lifting, angle, and distance, adapting to the clamping needs of objects at different positions, heights, and angles, making it suitable for a wide range of scenarios. The components work together via hinges, threaded connections, and other means, ensuring smooth movement and tight coordination, thus guaranteeing the precision of adjustment and clamping actions.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an engineering robot manipulator, including a base plate 1, a rotating component 2, a lifting hydraulic cylinder 3, an angle adjusting component 4, and a distance adjusting hydraulic cylinder 5. The rotating component 2 is disposed above the base plate 1, the lifting hydraulic cylinder 3 is vertically disposed above the rotating component 2, the angle adjusting component 4 is disposed at the output end of the lifting hydraulic cylinder 3, and the distance adjusting hydraulic cylinder 5 is horizontally disposed on the angle adjusting component 4. A clamping component 6 is disposed at the output end of the distance adjusting hydraulic cylinder 5. The rotating component 2 is used to drive the lifting hydraulic cylinder 3, the angle adjusting component 4, the distance adjusting hydraulic cylinder 5, and the clamping component 6 to rotate, changing the clamping direction. The lifting hydraulic cylinder 3 is used to adjust the clamping height. The length hydraulic cylinder adjusts the angle through the angle adjusting component 4, thereby adjusting the angle of the clamping component 6 to change the clamping angle distance. The distance adjusting hydraulic cylinder 5 is used to adjust the distance between the clamping component 6 and the object to be clamped.

[0020] Furthermore, the rotating assembly 2 includes a U-shaped frame 201, a rotary motor 202, and a turntable 203. The U-shaped frame 201 is fixed above the base plate 1, the turntable 203 is rotatably connected above the U-shaped frame 201, the rotary motor 202 is fixed inside the U-shaped frame 201, and the drive shaft of the rotary motor 202 is connected to the center of the turntable 203. The bottom of the lifting hydraulic cylinder 3 is fixed above the turntable 203. The rotary motor 202 drives the turntable 203 to rotate, which in turn drives the lifting hydraulic cylinder 3 to rotate, thereby driving the angle adjustment assembly 4, the distance adjustment hydraulic cylinder 5, and the clamping assembly 6 to rotate.

[0021] Furthermore, the angle adjustment assembly 4 includes a mounting base 401, a first hinge base 402, a first connecting shaft 403, a second hinge base 404, a second connecting shaft 405, an angle adjustment hydraulic cylinder 406, a third hinge base 407, and a connecting block 408. The mounting base 401 is fixed to the output end of the lifting hydraulic cylinder 3. The first hinge base 402 is fixed above the mounting base 401. The first connecting shaft 403 is hinged to the inner side of the first hinge base 402. The distance adjustment hydraulic cylinder 5 is fixed to the first connecting shaft 403. The second hinge base 404 is fixed to the side of the mounting base 401. The second connecting shaft 405 is hinged to the inner side of the second hinge base 404. The angle adjustment hydraulic cylinder 406 is fixed to the second connecting shaft 405. The third hinge base 407 is fixed to the output end of the angle adjustment hydraulic cylinder 406. The connecting block 408 is hinged to the inner side of the third hinge base 407 and is fixed to the side of the distance adjustment hydraulic cylinder 5. The angle adjustment hydraulic cylinder 406 outputs, causing the angle adjustment hydraulic rod to push the distance adjustment hydraulic cylinder 5, causing the distance adjustment hydraulic cylinder 5 to tilt. During this process, the first connecting shaft 403 will rotate within the first hinge seat 402, the second connecting shaft 405 will rotate within the second hinge seat 404, and the connecting block 408 will rotate within the third hinge seat 407.

[0022] Furthermore, the clamping assembly 6 includes a slide rail 601, a bidirectional lead screw 602, a lead screw slider 603, a drive motor 604, and a clamping plate 605. The slide rail 601 is fixed to the output end of the distance adjusting hydraulic cylinder 5. The bidirectional lead screw 602 is rotatably connected to the inner side of the slide rail 601. Two lead screw sliders 603 are symmetrically threaded onto the bidirectional lead screw 602. Each lead screw slider 603 is fixed with a clamping plate 605. The drive motor 604 is fixed to the end of the slide rail 601, and the drive shaft of the drive motor 604 is connected to the bidirectional lead screw 602. The drive motor 604 drives the bidirectional lead screw 602 to rotate, thereby driving the two lead screw sliders 603 to move relative to each other. When the two lead screw sliders 603 approach each other, they will cause the clamping plate 605 to clamp the object.

[0023] Furthermore, the lead screw slider 603 is fitted against the inner wall of the slide rail 601, and a sliding connection is adopted between the lead screw slider 603 and the slide rail 601. This restricts the lead screw slider 603 and improves the stability of its movement.

[0024] Furthermore, a pad 6051, which is a rubber pad, is provided on the clamping plate 605. The rubber pad is mainly used to avoid hard contact between the clamping plate 605 and the object being clamped, and to improve the anti-slip effect.

[0025] The rotary motor 202, lifting hydraulic cylinder 3, angle adjusting hydraulic cylinder 406, distance adjusting hydraulic cylinder 5, and drive motor 604 are all connected and controlled through a central control system. Rotary motor 202 is a servo motor; lifting hydraulic cylinder 3 is a single-piston rod hydraulic cylinder; angle adjusting hydraulic cylinder 406 is a small double-acting hydraulic cylinder; distance adjusting hydraulic cylinder 5 is a single-piston rod hydraulic cylinder; and drive motor 604 is a stepper motor. In summary, this engineering robot's manipulator achieves flexible gripping and manipulation of objects through the coordinated operation of multiple components. During use, the rotary motor 202 in the rotating component 2 drives the turntable 203 to rotate, causing the lifting hydraulic cylinder 3, angle adjustment component 4, distance adjustment hydraulic cylinder 5, and gripping component 6 to rotate as a whole, thereby changing the gripping direction. The lifting hydraulic cylinder 3 extends and retracts, directly adjusting the height of the entire manipulator (including the angle adjustment component 4, distance adjustment hydraulic cylinder 5, and gripping component 6) to accommodate objects of different heights. The angle adjustment hydraulic cylinder 406 outputs power to tilt the distance adjustment hydraulic cylinder 5. During this process, the first connecting shaft 403 rotates within the first hinge seat 402, the second connecting shaft 405 rotates within the second hinge seat 404, and the connecting block 408 rotates within the third hinge seat 407, collectively achieving angle changes in the distance adjustment hydraulic cylinder 5 and gripping component 6. The extension and retraction of the distance adjustment hydraulic cylinder 5 changes the horizontal distance between the gripping component 6 and the object to be gripped, allowing it to precisely approach the target. In the clamping assembly 6, the drive motor 604 drives the bidirectional lead screw 602 to rotate. The bidirectional lead screw 602 drives two symmetrical lead screw sliders 603 to slide along the slide rail 601 (because the lead screw sliders 603 are slidably connected to the slide rail 601 and fit against the inner wall, stability is ensured), causing the clamping plates 605 to move closer or further apart. When they move closer, the clamping plates 605 (including the rubber pad 6051) complete the clamping of the object; the rubber pad 6051 can avoid hard contact and enhance the anti-slip effect.

[0026] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
