Technical Field

[0001] The utility model relates to the technical field of automobile production and manufacturing, in particular to a turning device for an automobile production positioning mechanism. Background Art

[0002] During automobile production, robots are usually used to assist in the work. During the production and processing of automobile bodies, the robot has two states in the positioning mechanism of the automobile: clamping state and opening state. The opening state is used for manually loading scattered parts and taking away finished parts after welding work is completed, and the clamping state is used for positioning the accuracy and fixation of automobile products. The above mechanisms are necessary and commonly used mechanisms in the automobile welding industry. Automobile production is currently one of the country's important economic sources, so optimization during automobile production is also necessary.

[0003] For example, a Chinese utility model patent with announcement number CN215999250U discloses a U-shaped aluminum body welding positioning tool. Although the above-mentioned prior art effectively ensures the smooth installation and positioning accuracy of the U-shaped aluminum body, and can realize the welding positioning of aluminum profiles of multiple specifications, reducing the cost of fixture development, but due to the diversification of automobile products, the positions of the positioning holes of automobile parts themselves are different, and the size of existing equipment on the production site makes it impossible to change the height size limit of all automobile products, so that the body positioning mechanism, after opening, will partially block the manual operation of loading or removing parts, and there is a collision safety risk problem. Therefore, it is necessary to design a simple flipping device for a robot that can be flipped after the automobile product is processed to facilitate the staff to load or remove automobile products. Utility Model Content

[0008] Through the above technical solution, the rotation of the movable support will cause the positioning assembly to flip.

[0009] As a further improvement of the above scheme, a mounting groove penetrating the support connecting piece is provided on one side of the support connecting piece, a rotating groove matched with the support connecting piece is provided on one side of the fixed base, a connecting rod is rotatably installed inside the mounting groove, both ends of the connecting rod pass through the rotating groove and extend to the outside of the fixed base, and lubricating gaskets sleeved on the connecting rods are provided on both sides of the support connecting piece, and one side of the two lubricating gaskets is in contact with the inner wall of the rotating groove.

[0010] Through the above technical solution, the support connector drives the movable support to rotate, so that the positioning component can produce a flipping effect.

[0011] As a further improvement of the above scheme, a drive port is opened on one side of the mounting plate, and the drive assembly includes a cylinder fixedly mounted on the drive port, a push rod fixedly mounted on the output end of the cylinder, a connector fixedly mounted on one end of the push rod, and a cylinder connecting part fixedly mounted on one side of the movable support and rotatably matched with the connector.

[0012] Through the above technical solution, under the push of the cylinder, the push rod will allow the connector and the cylinder connecting piece to push the movable support to complete the flipping of the positioning component.

[0013] As a further improvement of the above scheme, the buffer assembly includes a first connecting plate fixedly installed on one side of the movable support, a buffer fixedly installed on one side of the first connecting plate, a second connecting plate fixedly mounted on the buffer, and a third connecting plate fixedly installed on one side of the second connecting plate and rotatably installed with the fixed base.

[0014] Through the above technical solution, the buffer will provide a certain buffering force during the flipping process of the positioning component.

[0015] As a further improvement of the above solution, a first limit block is fixedly installed on one side of the fixed base, and a second limit block adapted to the first limit block is fixedly installed on one side of the support connector.

[0016] The above technical solution can prevent the flipping angle of the positioning component from being too large.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a flip assembly, a drive assembly and a buffer assembly, so that when it is necessary to open the positioning assembly to load and unload the automobile product during automobile production, the drive assembly will generate a push to rotate the flip assembly connected to the positioning assembly, thereby allowing the positioning assembly to move to facilitate the staff to open the positioning assembly to load and unload the automobile product. The buffer assembly will also provide a certain buffering effect when the positioning assembly rotates, thereby preventing the positioning assembly from rotating too fast and causing damage to the automobile product.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A flipping device for an automobile production positioning mechanism of this embodiment includes a mounting plate 1, one side of the mounting plate 1 is provided with a plurality of positioning components 2 for clamping or opening the automobile body during the production process, a flipping component for driving the adjacent positioning components 2 to flip is provided between every two positioning components 2, one side of each flipping component is provided with a driving component for driving the flipping component to flip, and the other side of each flipping component is provided with two buffer components for providing buffering when the flipping component is flipped.

[0027] Combination Figure 2-Figure 4The flip assembly includes a movable support 301 fixedly installed between the two positioning assemblies 2, a support connector 302 fixedly installed on one side of the movable support 301, and a fixed base 303 arranged on one side of the support connector 302 and fixedly installed with the mounting plate 1. A mounting groove penetrating the support connector 302 is provided on one side of the support connector 302, and a rotating groove matched with the support connector 302 is provided on one side of the fixed base 303. A connecting rod 6 is rotatably installed inside the mounting groove. Both ends of the connecting rod 6 penetrate the rotating groove and extend to the outside of the fixed base 303. Lubricating gaskets 7 sleeved on the connecting rod 6 are provided on both sides of the support connector 302. One side of the two lubricating gaskets 7 are both in contact with the inner wall of the rotating groove. The support connector 302 drives the movable support 301 to rotate, so that the positioning assembly 2 can produce a flipping effect.

[0028] Combination Figure 1 and Figure 2 A driving port is provided on one side of the mounting plate 1, and the driving assembly includes a cylinder 401 fixedly mounted on the driving port, a pushing rod 402 fixedly mounted on the output end of the cylinder 401, a connector 403 fixedly mounted on one end of the pushing rod 402, and a cylinder connector 404 fixedly mounted on one side of the movable support 301 and rotatably matched with the connector 403. Under the push of the cylinder 401, the pushing rod 402 will allow the connector 403 and the cylinder connector 404 to push the movable support 301 to complete the flipping of the positioning assembly 2.

[0029] Combination Figure 3 and Figure 4 The buffer assembly includes a first connecting plate 501 fixedly mounted on one side of the movable support 301, a buffer 502 fixedly mounted on one side of the first connecting plate 501, a second connecting plate 503 fixedly mounted on the buffer 502, and a third connecting plate 504 fixedly mounted on one side of the second connecting plate 503 and rotatably mounted with the fixed base 303. During the flipping process of the positioning assembly 2, the buffer 502 will provide a certain buffering force.

[0030] Combination Figure 2 and Figure 3 A first limit block 8 is fixedly installed on one side of the fixed base 303, and a second limit block 9 adapted to the first limit block 8 is fixedly installed on one side of the support connector 302 to prevent the positioning assembly 2 from flipping too much.

[0031] The implementation principle of a flip device for an automobile production positioning mechanism in the embodiment of the present application is as follows: when the staff uses the positioning component 2 to fix the loading or unloading of the automobile product, the cylinder 401 will start, and the push rod 402 will push the connector 403 and the cylinder connector 404 to move together, which will push the movable support 301, and the movable support 301 is supported by the support connector 302 and the fixed base 303. The center point of the rotation of the movable support 301 is the position of the connecting rod 6, and the two positioning components 2 are driven to rotate along the connecting rod 6 as the center point. While rotating, the first connecting plate 501 will squeeze the buffer 502 to reduce the rotation speed to prevent problems caused by excessive rotation speed, and the maximum rotation angle will also be limited by the first limit block 8 and the second limit block 9. In this way, when positioning, installing or removing automobile products, the positioning component 2 can be moved to a certain position first, and the degree of opening of the positioning component 2 after moving will be different, so as to avoid the inconvenience of removing or installing automobile products after the positioning component 2 is opened.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
