Description

Technical Field

[0001] The utility model relates to the technical field of industrial robot manufacturing, in particular to a displacement tool fixture of an industrial robot manufacturing unit. Background Art

[0002] In modern manufacturing, as an important part of the flexible manufacturing system (FMS), the fixture realizes industrial automation by quickly clamping and handling the workpiece. Its application not only improves production efficiency, but also reduces production costs, becoming one of the core advantages of the flexible manufacturing system. However, with the continuous improvement of processing requirements, the shapes of parts are becoming more and more complex. In the actual production process, due to the differences in workpiece shapes and sizes and the diversity of process flows, the fixture needs to be frequently replaced to meet the needs of different clamping angles or positions. Its production efficiency needs to be further improved, so as to further reduce production costs.

[0003] For example, the existing patent technology discloses a mechanical arm (patent application number: CN 201721607156.1), which realizes industrial automation control by setting a push cylinder, a support arm, a clamp and a magnetic switch. It can automatically control the closing and opening of the clamp according to the actual needs of use, thereby loosening and clamping the product or workpiece. It has a simple structure and is easy to use and reliable. However, since it cannot realize the function of displacement clamping and cannot meet the clamping requirements of increasingly complex workpieces, its scope of use is limited. Therefore, it is very necessary to design a displacement fixture that can automatically adjust the position and posture. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to provide a displacement fixture of an industrial robot manufacturing unit, which realizes flexible adjustment and positioning of the fixture by setting joints and drive units with multiple degrees of freedom, enhances the flexibility of production, and enables the clamp or suction cup to automatically adjust the position and posture of the clamp according to the position, shape and size of the workpiece, thereby reducing the time for replacing the fixture, improving production efficiency and reducing production costs.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a displacement fixture of an industrial robot manufacturing unit, including a connecting plate, a first bracket and a second bracket are respectively arranged on both sides of the connecting plate, a servo drive motor is arranged inside the first bracket, a bearing seat is arranged inside the second bracket, a displacement bracket plate is rotatably arranged between the first bracket and the second bracket, a cross-shaped connecting shaft is arranged at both ends of the displacement bracket plate, the connecting shaft at one end of the displacement bracket plate is connected to the servo drive motor through a coupling, and the connecting shaft at the other end of the displacement bracket plate is rotatably connected to the bearing seat. Through the action of the servo drive motor, it drives the displacement bracket plate to rotate between the first bracket and the second bracket, which makes the displacement bracket plate form a first displacement axis.

[0006] The displacement bracket plate is provided with four groups of rotating clamping assemblies, which include a rotating unit and a clamping unit arranged above the rotating unit. Each group of the rotating unit and the clamping unit are controlled separately, and the movements between them do not interfere with each other, and the rotating unit forms a second displacement axis.

[0007] Preferably, the rotation unit includes a rotation driving part and a transition plate connected to the output end of the rotation driving part, the rotation driving part is connected to the displacement bracket plate, and the transition plate is connected to the rotation driving part.

[0008] Furthermore, the clamping unit is a pneumatic clamping claw unit or a pneumatic suction cup unit. In actual use, a clamping unit that is compatible with the workpiece to be clamped can be selected according to the structural characteristics of the workpiece to be clamped.

[0009] Furthermore, the pneumatic clamping jaw unit includes a clamping cylinder and a clamping jaw connected to the clamping cylinder, wherein the clamping jaws are two and are respectively connected to the clamping slide block of the clamping cylinder. A magnetic switch is provided on the clamping cylinder to provide real-time feedback on the position of the clamping jaw.

[0010] Furthermore, the clamping portion of the clamping jaw is in a plane straight line shape or an inner arc shape, and a suitable clamping jaw is selected according to actual needs during use.

[0011] Furthermore, the pneumatic suction cup unit includes a support block and a vacuum suction cup portion arranged on one side of the support block.

[0012] Furthermore, the rotary drive unit is a rotary cylinder or a low-speed motor. The rotary drive unit with a rotary cylinder structure has a fast response speed, but a relatively low positioning accuracy, while the rotary drive unit with a low-speed motor structure has a relatively slow response speed, but a relatively high positioning accuracy. The suitable rotary drive unit can be selected according to actual needs.

[0013] The beneficial effects of the utility model are: (1) by setting joints and drive units with multiple degrees of freedom, the position and posture of the clamp or suction cup can be automatically adjusted according to the position, shape and size of the workpiece, thereby reducing the time for replacing the clamp and improving production efficiency; (2) it can better adapt to the needs of various workpieces and process flows, reduce the design and manufacturing costs of special clamps, and reduce production costs; (3) by real-time monitoring of the working status of the clamp, the accuracy and stability of the clamp's clamping are ensured, making it more reliable to use.

DETAILED DESCRIPTION

[0021] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model. Example

[0022] like Figures 1 to 4As shown, a displacement fixture of an industrial robot manufacturing unit includes a connecting plate 100, a first bracket 200 and a second bracket 300 are respectively arranged on both sides of the connecting plate 100, a servo drive motor (which is an existing installation structure, not shown in the figure) is arranged inside the first bracket 200, a bearing seat 400 is arranged inside the second bracket 300, a displacement bracket plate 500 is rotatably arranged between the first bracket 200 and the second bracket 300, and a cross-shaped connecting shaft 600 is arranged at both ends of the displacement bracket plate 500, the connecting shaft 600 at the left end of the displacement bracket plate 500 is connected to the servo drive motor through a coupling, and the connecting shaft 600 at the right end of the displacement bracket plate 500 is rotatably connected to the bearing seat 400. Through the action of the servo drive motor, it drives the displacement bracket plate 500 to rotate between the first bracket 200 and the second bracket 300, so that the displacement bracket plate 500 forms a first displacement axis and drives the rotating clamping assembly 700 to rotate around the X axis.

[0023] Four groups of rotating clamping assemblies 700 are all arranged on the displacement bracket plate 500, and the rotating clamping assemblies 700 include a rotating unit 710 and a clamping unit 720 arranged above the rotating unit 710. Each group of the rotating unit 710 and the clamping unit 720 are controlled separately, and the movements between them do not interfere with each other. The rotating unit 710 forms a second displacement axis, driving the clamping unit 720 to rotate around the Y axis.

[0024] The rotating unit 710 includes a rotating driving part 711 and a transition plate 712 connected to the output end of the rotating driving part 711 . The rotating driving part 711 is connected to the displacement bracket plate 500 , and the transition plate 712 is connected to the rotating driving part 711 .

[0025] The rotation driving unit 711 is a low-speed motor. The response speed of the rotation driving unit 711 with a low-speed motor structure is relatively slow, but the position accuracy is relatively high.

[0026] The clamping unit 720 is a pneumatic clamping jaw unit 720a, which includes a clamping cylinder 721 and a clamping jaw 722 connected to the clamping cylinder 721. The clamping jaw 722 is two and is respectively connected to a clamping slider 723 of the clamping cylinder 721. The clamping cylinder 721 is provided with a magnetic switch, which can provide real-time feedback on the position of the clamping jaw 722.

[0027] The clamping portion of the clamping jaw 722 is in a plane straight line shape or an inner arc shape. When in use, a suitable clamping jaw is selected according to actual needs.

[0028] like Figures 1 to 4As shown, before use, the tooling fixture is assembled on the robot's mechanical arm. When in use, according to the position and shape of the workpiece, the servo drive motor is started and drives the rotating clamping assembly 700 to rotate a certain angle around the X-axis. Then the rotating unit 710 drives the clamping unit 720 to rotate to a suitable position around the Y-axis to facilitate the grasping of the workpiece. Example

[0029] like Figures 1 to 5 As shown, different from Example 1, in actual use, the pneumatic suction cup unit 720b can also be selected as the clamping unit 720 according to the structural characteristics of the clamped workpiece (for example, a workpiece with a smooth surface and a large size such as a car roof, a template, etc.), and the pneumatic suction cup unit 720b includes a support block 731 and a vacuum suction cup part 732 arranged on one side of the support block 731. When in use, according to the position and shape of the workpiece, the servo drive motor starts and drives the rotary clamping assembly 700 to rotate a certain angle around the X-axis, so that the vacuum suction cup part 732 can adapt to the gripping angle of the workpiece.

[0030] The utility model enhances the flexibility of production, so that the clamping jaw 722 or the vacuum suction cup part 732 can automatically adjust the position and posture of the clamping jaw 722 or the vacuum suction cup part 732 according to the position, shape and size of the workpiece, thereby reducing the time for replacing the clamp, improving production efficiency and reducing production costs.
