Description

Technical Field

[0001] This utility model relates to the field of automotive sheet metal processing technology, and specifically discloses an automotive sheet metal stamping positioning device. Background Technology

[0002] Automotive sheet metal parts are metal components that make up the car body and related structures. They are mainly made of metal materials such as steel plates and aluminum alloys, and are manufactured through processing techniques such as stamping, welding, and bending. They are the core components of the car body structure and appearance. During the stamping process of sheet metal parts, it is usually necessary to use a positioning device to position the sheet metal parts so that the target stamping position is quickly aligned with the stamping press.

[0003] Chinese patent CN212190935U discloses a positioning device for stamping automotive sheet metal parts. This device can position sheet metal parts of different models, is easy to operate, and reduces limitations in use. It includes a placement platform for the sheet metal parts; two sets of strip plates and two sets of right-angle positioning plates. The rear half of the top of the placement platform is provided with an inner arc-shaped groove and an outer arc-shaped groove. Two sets of inner circular sliding plates and two sets of outer circular sliding plates are slidably mounted on the inner and outer arc-shaped grooves, respectively. A first fixing screw is provided at the top of each of the two sets of inner circular sliding plates. The top of each of the outer circular sliding plates is provided with a second fixing screw, and each of the two sets of strip plates is provided with a through-hole strip, and also includes a first fixing nut and a second fixing nut. The two sets of right-angle positioning plates are respectively installed at the ends of the two sets of strip plates. However, when the angle of the right-angle positioning plate needs to be adjusted during use, the strip plate must be adjusted together, which makes the angle adjustment of the right-angle positioning plate not flexible enough and affects the practicality of the above device to a certain extent. Therefore, in order to solve the above problems, this utility model proposes a stamping positioning device for automotive sheet metal parts. Utility Model Content

[0004] The present invention aims to provide a stamping positioning device for automotive sheet metal parts, which can adjust the angle of the right-angle positioning plate while keeping the support plate stationary, thereby improving the flexibility of the angle adjustment of the right-angle positioning plate and the practicality of the device.

[0005] This utility model is achieved through the following technical solution: A stamping positioning device for automotive sheet metal parts includes a base with two supporting positioning mechanisms on top. The base includes a bearing plate with a limit groove on its inner side and a limit block on its inner side. A support shaft is located at the center of the upper part of the limit block. Each supporting positioning mechanism includes a support plate with a connecting seat at one end. A second scale plate is located at the upper end of the connecting seat. A bolt passes through the interior of the connecting seat. A right-angle positioning plate is located at the end of the connecting seat away from the support plate. A mounting seat is located at the center of the side of the right-angle positioning plate near the connecting seat. The bolt passes through the interior of the mounting seat. A stop plate is located at the side of the right-angle positioning plate away from the connecting seat. Two connecting shafts are symmetrically arranged at one end of the stop plate.

[0006] As a further feature of the above solution, mounting plates are provided at both ends of the lower part of the support plate. The mounting plates have mounting holes inside, which facilitates the installation of the base and the device together on one side of the original stamping device (not shown). Both ends of the limiting groove are detachably connected to sealing plates, which facilitates the installation and removal of the sealing plates and provides convenience for the limiting block to be placed in the limiting groove. The limiting block is slidably connected to the limiting groove. A first scale plate is provided on the upper side of the support plate, which facilitates the user to accurately adjust the position of the two support shafts and the support positioning mechanism.

[0007] As a further feature of the above solution, the support plate has an elongated hole inside, the support shaft passes through the elongated hole, a first washer is fitted on the outside of the support shaft, and a first nut is threaded onto the outside of the support shaft, which facilitates the adjustment and fixing of the distance between the connecting seat and the right-angle positioning plate and other components and the bearing plate.

[0008] As a further feature of the above solution, a second washer is fitted on the outer side of the bolt, and a second nut is threaded onto the outer side of the bolt. This allows the user to loosen the second nut before adjusting the angle of the right-angle positioning plate, so that the mounting base rotates around the bolt as the rotation axis on the inner side of the connecting base. After the right-angle positioning plate stops rotating, the second nut is tightened to fix the mounting base and the right-angle positioning plate. An arrow is provided on the side of the right-angle positioning plate near the connecting base to help the user determine the scale on the second scale plate corresponding to the right-angle positioning plate and to determine the angle between the right-angle positioning plate and the abutment.

[0009] As a further feature of the above solution, two limiting holes are symmetrically arranged on one side of the right-angle positioning plate. The connecting shaft passes through the inside of the limiting holes. A third washer is sleeved on the outside of the connecting shaft. A third nut is threaded onto the outside of the connecting shaft, which facilitates the user to adjust and fix the position of the abutment plate, thereby adjusting the maximum depth of the sheet metal part extending into the inside of the two right-angle positioning plates. A third scale plate is provided on the side of the right-angle positioning plate near the third nut, which facilitates the user to determine the position of the abutment plate.

[0010] The scale lines of the second scale plate in this utility model are from 0 degrees to 180 degrees.

[0011] The present invention has the following beneficial effects during use: The use of the first scale plate in the base allows the user to easily determine the distance between the two limit blocks, the support shaft, and the support plate. The combination of the connecting seat, the second scale plate, the bolt, the second nut, the mounting seat, and the arrow allows the second nut to be loosened while the connecting seat and the support plate remain stationary. This releases the restriction on the mounting seat, allowing it to rotate around the bolt as a pivot point inside the connecting seat. When the pointer points to the target angle, rotation stops, and the second nut is tightened to fix the angle of the mounting seat and the right-angle positioning plate, improving the flexibility of adjusting the angle of the right-angle positioning plate. The combination of the abutment plate, the third nut, and the third scale plate allows the user to adjust the distance between the abutment plate and the mounting seat according to their needs, thereby adjusting the depth of the sheet metal part extending between the two right-angle positioning plates based on the position of the stamping die and the stamping requirements.
