Description

Technical Field

[0001] The present application relates to the technical field of positioning mechanisms, and in particular to a flip positioning device. Background Art

[0002] At present, in the flexible production process of automobiles, in order to save layout space and production costs, workpieces with similar vehicle structures are generally planned to share a set of welding equipment. When the workpiece structures are quite different and there are no common positioning holes and / or positioning surfaces on different workpiece structures, if a fixture is to be able to adapt to multiple workpieces at the same time, the fixture structure shared by the welding equipment will be extremely complicated, and such workpieces usually need to be made of special fixtures. Such special fixtures are often used to switch the vehicle fixture position through structures such as slide storage positions and multi-faceted rotating bodies.

[0003] However, when multiple workpieces share a set of positioning equipment, the fixture structure corresponding to each workpiece on the positioning equipment is relatively simple, and the positioning accuracy of the workpiece is not high; and since there are many types of fixtures corresponding to different types of workpieces on the positioning equipment, the positioning equipment as a whole has the defects of complex fixture structure, large space occupation and high investment cost. Utility Model Content

[0004] The present application aims to provide a flip positioning device in view of the deficiencies in the prior art.

[0005] The technical solution of this application to solve the above technical problems is as follows:

[0006] A flip positioning device comprises a fixed frame and a flip limiting mechanism arranged on both sides of the fixed frame. The flip limiting mechanism is rotatably connected to the fixed frame along its axial direction. The two flip limiting mechanisms cooperate to provide limiting support for both ends of a workpiece. The flip limiting mechanism is a polygonal prism structure. The prism surface of the flip limiting mechanism is used to perform limiting operations on different types of workpieces.

[0007] By adopting the above technical solution, when the workpiece needs to be limited and supported, the flip limit mechanism rotates relative to the fixed frame along its own axial direction, and the side of the flip limit mechanism that matches the current workpiece is rotated upward. When the operator places the workpiece above the fixed frame, the flip limit mechanism limits the workpiece. When different types of workpieces need to be limited, by rotating the flip limit mechanism, the side of the flip limit mechanism can limit different types of workpieces respectively, which is conducive to simplifying the structure of the positioning device, saving space, and simplifying the limiting operation process.

[0008] Furthermore, the flipping limit mechanism includes a flipping tetrahedron, and the first limit component, the second limit component, the third limit component and the fourth limit component are respectively arranged on the four sides of the flipping tetrahedron, and the first limit component, the second limit component, the third limit component and the fourth limit component are respectively adapted to different workpieces.

[0009] By adopting the above technical solution, the first limit assembly, the second limit assembly, the third limit assembly and the fourth limit assembly are respectively adapted to different workpieces. When the workpiece needs to be limited, the operator selects the limit assembly corresponding to the current workpiece to realize the stable limiting function of the flip tetrahedron for multiple workpieces.

[0010] Furthermore, the flip limiting mechanism is rotatably connected to the fixed frame via a flip beam.

[0011] Furthermore, a driving motor is provided on the fixed frame, and the driving motor is used to drive the flip beam to rotate.

[0012] By adopting the above technical solution, when it is necessary to drive the flip tetrahedron to rotate, the output shaft of the driving motor passes through the fixed frame, driving the flip beam to rotate, and the flip beams located at both ends of the flip tetrahedron jointly drive the flip tetrahedron to rotate, thereby realizing the switching process of the limit assembly.

[0013] Furthermore, the fixed frame is provided with a limit cylinder and a limit block connected to the output shaft of the limit cylinder, and the limit block is located below the flip beam and is used for abutting and limiting the flip beam.

[0014] By adopting the above technical solution, the limit cylinder is arranged in the vertical direction. When the flip tetrahedron rotates, the output shaft of the limit cylinder contracts, driving the limit block to move downward, thereby providing avoidance space for the rotation of the flip tetrahedron; when the flip tetrahedron rotates to the required position, the output shaft of the limit cylinder extends out, driving the limit block to move upward, thereby abutting against the lower end surface of the flip beam, abutting and limiting the flip beam, so that the flip tetrahedron is not easy to deviate when performing the workpiece limiting operation, thereby improving the stability of the workpiece positioning.

[0015] In summary, compared with the prior art, the above technical solution has the following beneficial effects:

[0016] The flip positioning device described in the present application, when the workpiece needs to be limited and supported, the flip limiting mechanism rotates relative to the fixed frame along its own axial direction, and the side of the flip limiting mechanism adapted to the current workpiece is rotated upward, and when the operator places the workpiece above the fixed frame, the flip limiting mechanism limits the workpiece. When different types of workpieces need to be limited, by rotating the flip limiting mechanism, the side of the flip limiting mechanism can limit different types of workpieces respectively, which is conducive to simplifying the positioning device structure, saving space, and simplifying the limiting operation process.

[0020] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0021] The embodiment of the present application discloses a flip positioning device.

[0022] Reference Figure 1-Figure 2 A flip positioning device includes a fixed frame 1 and a flip limiting mechanism 2 arranged on both sides of the fixed frame 1. The two flip limiting mechanisms 2 are located at the same height and are both arranged in the horizontal direction. The flip limiting mechanism 2 is rotatably connected to the fixed frame 1 along its axial direction. The two flip limiting mechanisms 2 cooperate to limit and support the two ends of the workpiece. The flip limiting mechanism 2 has a polygonal prism structure, and the prism surface of the flip limiting mechanism 2 is used to limit different types of workpieces.

[0023] When the workpiece needs to be limited and supported, the flip limit mechanism 2 rotates relative to the fixed frame 1 along its own axial direction, and the side of the flip limit mechanism 2 adapted to the current workpiece is rotated upward. When the operator places the workpiece above the fixed frame 1, the flip limit mechanism 2 limits the workpiece. When different types of workpieces need to be limited, by rotating the flip limit mechanism 2, the side of the flip limit mechanism 2 can limit different types of workpieces respectively, which is conducive to simplifying the structure of the positioning device, saving space, and simplifying the limiting operation process.

[0024] In the embodiment of the present application, the flip limit mechanism 2 includes a flip tetrahedron 21, and the four sides of the flip tetrahedron 21 are respectively provided with a first limit component, a second limit component, a third limit component and a fourth limit component, and the first limit component, the second limit component, the third limit component and the fourth limit component are respectively adapted to different workpieces. For example, the first limit component is used to provide limited support for workpiece A, and a positioning block and a positioning pin are fixed on the first limit component, and the positioning block and the positioning pin are both adapted to the contour of workpiece A. When the first limit component is working, the positioning block abuts against the workpiece A, and the positioning pin is connected to the pin hole opened on the workpiece A.

[0025] Both ends of the flip tetrahedron 21 are fixedly provided with flip beams 3, and the flip tetrahedron 21 is rotatably connected to the fixed frame 1 through the flip beams 3. The fixed frame 1 is provided with a driving motor 4, and the driving motor 4 is used to drive the flip beam 3 to rotate. When it is necessary to drive the flip tetrahedron 21 to rotate, the output shaft of the driving motor 4 passes through the fixed frame 1, driving the flip beam 3 to rotate, and the flip beams 3 located at both ends of the flip tetrahedron 21 jointly drive the flip tetrahedron 21 to rotate, realizing the switching process of the limit assembly.

[0026] The fixed frame 1 is provided with a limit cylinder 5 and a limit block 6 connected to the output shaft of the limit cylinder 5. The limit block 6 is located below the flip beam 3 and is used to abut and limit the flip beam 3. The limit cylinder 5 is arranged in the vertical direction. When the flip tetrahedron 21 rotates, the output shaft of the limit cylinder 5 contracts, driving the limit block 6 to move downward, providing an escape space for the rotation of the flip tetrahedron 21; when the flip tetrahedron 21 rotates to the desired position, the output shaft of the limit cylinder 5 extends, driving the limit block 6 to move upward, thereby abutting against the lower end surface of the flip beam 3, abutting and limiting the flip beam 3, so that the flip tetrahedron 21 is not easy to deviate when performing the workpiece limiting operation, thereby improving the stability of the workpiece positioning.

[0027] The implementation principle of a flip positioning device in the embodiment of the present application is as follows: when the workpiece needs to be limited and supported, the flip limiting mechanism 2 rotates relative to the fixed frame 1 along its own axial direction, and the side of the flip limiting mechanism 2 adapted to the current workpiece is rotated upward, and when the operator places the workpiece above the fixed frame 1, the flip limiting mechanism 2 limits the workpiece. When different types of workpieces need to be limited, by rotating the flip limiting mechanism 2, the side of the flip limiting mechanism 2 can limit different types of workpieces respectively, which is conducive to simplifying the structure of the positioning device, saving space, and simplifying the limiting operation process.

[0028] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
