Description

Technical Field

[0001] The utility model belongs to the technical field of automobile stamping parts processing, in particular to a stamping positioning mechanism for automobile stamping parts. Background Art

[0002] Automotive stamping parts are metal stamping parts that constitute automotive parts. Among automotive stamping parts, some become automotive parts directly after stamping, while the other parts need to go through welding, machining or painting and other processing after stamping before they can become automotive parts.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: before processing automobile stamping parts, they need to be positioned using a positioning mechanism, but the current positioning mechanism usually cannot limit the vertical direction of the stamping parts, which may cause warping and irregular deformation on both sides of the stamping parts during the stamping process, thereby reducing the precision of the stamping parts.

[0004] Therefore, we propose a stamping positioning mechanism for automobile stamping parts to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a stamping positioning mechanism for automobile stamping parts, so that the automobile stamping parts will not have irregular changes in the horizontal and vertical directions, and will not produce warping, deformation and the like due to the action of the stamping head, thereby ensuring the precision of stamping and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A stamping positioning mechanism for automobile stamping parts, comprising a press platform, a stamping assembly and a positioning assembly located on the press platform, a receiving frame in an inverted U shape is fixedly welded at the center of the top wall of the press platform, and the stamping assembly comprises a hydraulic cylinder installed on the top wall of the receiving frame, a support plate connected to the bottom of the hydraulic cylinder, a stamping head integrally welded to the bottom wall of the support plate, and a receiving seat embedded and installed on the top wall of the press platform;

[0008] Top grooves are formed on both sides of the top wall of the press platform. The top groove has two openings and is symmetrical to the press platform. The positioning assembly includes two servo motors installed on one side wall of the press platform, screws coaxially connected to the output shafts of the two servo motors, inner sliders threadedly sleeved on both sides of the screw, and movable splints welded on the two inner sliders. The rotation directions on both sides of the screw are opposite. The two inner sliders on the screw are symmetrical in design, and the inner slider on the screw fits with the bottom wall of the top groove, so that when the screw is running, it can drive the inner sliders on both sides of it to translate in opposite directions or opposite directions along the inner wall of the top groove.

[0009] As a preferred embodiment, the receiving seat is designed in a U-shaped shape and is located directly below the punching head, and the opening of the receiving seat is adapted to the punching head; so that the punching head can punch the automobile stamping parts into the receiving seat, thereby completing the stamping work of the automobile stamping parts.

[0010] As a preferred embodiment, ear plates are welded on the opposite side walls of the receiving frame, cylinders are installed on the top walls of the two ear plates, and positioning plates are connected to the bottom of the two cylinders; the two positioning plates are respectively located above the two top grooves and are used to position the automobile stamping parts in the vertical direction.

[0011] As a preferred embodiment, the two screws are both arranged horizontally and parallel to each other, and the two screws are rotatably connected to the press table; so that the screws can operate stably under the drive of the servo motor.

[0012] As a preferred implementation scheme, gaskets are fixedly bonded on the opposite sides of the two movable splints on the screw rod; the material of the gasket can be selected from soft materials such as rubber, which are used to cushion the two sides of the automobile stamping parts. A gasket can also be bonded to the bottom wall of the two positioning plates to cushion the top of the automobile stamping parts.

[0013] In summary, the technical effects and advantages of the utility model are as follows:

[0014] The automobile stamping parts stamping positioning mechanism first performs dual positioning of the automobile stamping parts in the horizontal direction and the vertical direction before using the stamping assembly for stamping work, and the vertical positioning positions are just on both sides of the stamping position, so that the automobile stamping parts will not have irregular changes in the horizontal direction and the vertical direction, and will not cause warping and deformation due to the action of the stamping head, thereby ensuring the precision of stamping;

[0015] The automobile stamping part stamping positioning mechanism drives the hydraulic cylinder to operate and utilizes the support plate and the punch head to quickly press down during stamping, so as to press the automobile stamping part into the receiving seat and complete the stamping, and then reverses the two servo motors to release the fixation on both sides of the automobile stamping part, so that the two cylinders drive the two positioning plates to return to their original positions, release the fixation on the top of the automobile stamping part, and then remove the stamped part. After the stamping work of the stamping part is completed, the lock of the stamping part can be easily released for easy removal. BRIEF DESCRIPTION OF THE DRAWINGS
