Description

Technical Field

[0001] This application relates to the field of automotive rear panel processing technology, and more specifically, to a wedge-shaped positioning device for rear panels of new energy vehicles. Background Technology

[0002] As a key covering component at the rear of the vehicle body, the rear panel of a new energy vehicle is usually made of high-strength steel plate through multiple stamping processes. After forming, excess material needs to be removed by trimming to meet assembly size requirements.

[0003] In related technologies, to facilitate the unloading of automotive stamping parts, for example, the prior art patent with publication number CN216575278U provides a composite mold for cutting bevels and edges of automotive stamping parts. This mold has an unloading mechanism set at the top of the mounting plate. By utilizing the cooperation of the mounting cavity, transmission rack, cavity, servo motor, pulley structure, worm and worm wheel of the unloading mechanism, the processed parts can be lifted up, making it more convenient and faster to unload the processed parts, thereby greatly improving the working efficiency of the mold during use.

[0004] Although the existing technical solutions mentioned above facilitate the unloading of processed automotive stamping parts by setting up an unloading mechanism, the lower die lacks a positioning structure. For irregularly shaped automotive rear panel panels, it is impossible to achieve accurate and stable fixed positioning, making it difficult to adapt to their irregular contours and prevent interference during part placement, which in turn leads to poor dimensional consistency of the processed parts.

[0005] In view of this, we propose a wedge-shaped positioning device for the rear outer panel of new energy vehicles to avoid collisions. Utility Model Content

[0006] The purpose of this application is to provide a wedge-shaped positioning device for the rear outer panel of new energy vehicles, which can effectively solve the problem in the prior art that the lack of a positioning structure in the lower mold leads to the inability to accurately and stably fix the rear outer panels of new energy vehicles of different specifications, and achieves the effect of positioning the rear outer panel while avoiding interference during part placement.

[0007] This application provides a wedge-shaped positioning device for the rear outer panel of a new energy vehicle, including: A wedge assembly is disposed on the top of the lower mold, the wedge assembly being located on one side of the cutting edge insert; A positioning post is located on the outside of the wedge assembly, and the positioning post is driven by an external force to position the product sheet. The drive block, located at the bottom of the upper mold, is used to drive the positioning pin to move and perform avoidance actions.

[0008] As an optional solution to the technical solution of this application, the wedge assembly includes a mounting plate, which is fixedly disposed on the top of the lower mold. A clearance block is slidably disposed on the top of the wedge assembly. A mounting cover is fixedly disposed on the top of the mounting plate by screws. The positioning post is fixedly disposed on the side of the clearance block near the cutting edge insert. The clearance block is driven to move by a driving block.

[0009] As an optional solution of the technical solution in this application, the inner side of the avoidance block is provided with a mating opening, the inner side of the mounting plate is provided with a through opening A corresponding to the mating opening, the inner side of the mounting cover is provided with a through opening B corresponding to the mating opening, the inner side of the mating opening is fixedly provided with an inclined block A, and the bottom of the driving block is provided with an inclined block B that cooperates with the inclined block A.

[0010] As an optional solution to the technical solution of this application, the mounting cover has a sliding opening A on the side near the edge insert, and the sliding opening A is slidably disposed with the clearance block.

[0011] As an optional solution to the technical solution of this application, a reset component is provided on the side of the avoidance block away from the edge insert, which is used to drive the avoidance block to move for positioning.

[0012] As an optional solution to the technical solution of this application, the reset component includes a screw, and the side of the clearance block away from the positioning post has a threaded hole, the threaded hole is threaded with the screw, the mounting cover has a sliding port B corresponding to the screw, the screw is slidably disposed inside the sliding port B, and a spring is sleeved on the outside of the screw, the spring is disposed between the clearance block and the mounting cover.

[0013] As an optional solution to the technical solution in this application, a limit plate is fixedly provided on the side of the screw away from the clearance block.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: (1) This application uses a wedge assembly and a positioning post. The positioning post moves to the inside of the product sheet outline and then the product sheet is brought close to the positioning post. Positioning is completed. When the upper mold and the lower mold cooperate to process, the positioning post automatically moves away from the product sheet outline and does not interfere with the cutting. Therefore, it effectively solves the problem in the prior art that the lower mold has no positioning structure, which makes it impossible to accurately and stably fix the rear outer panel of new energy vehicles of different specifications. It achieves the effect of positioning the rear outer panel while avoiding interference of the placement of parts.

[0015] (2) This application can adjust the length of the screw outside the clearance block by means of threaded hole and screw thread engagement, so as to be applicable to product plates of different specifications. Furthermore, by setting spring, the spring is compressed when the inclined blocks A and B move together. When the product plate is processed, the upper mold moves up and the spring recovers to drive the clearance block to reset, which is convenient for the next processing. Attached Figure Description

Detailed Implementation

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figure 1 , Figure 2 and Figure 3This application discloses a wedge-shaped positioning device for the rear outer panel of a new energy vehicle, including a wedge assembly 1, which is disposed on the top of the lower mold 100. The wedge assembly 1 is located on one side of the edge trimming insert 101. A positioning post 2 is disposed on the outer side of the wedge assembly 1. The positioning post 2 is driven by an external force to position the product sheet. A driving block 3 is disposed at the bottom of the upper mold 200 to drive the positioning post 2 to move and perform an avoidance action.

[0019] The operator places the product sheet to be processed on the top of the lower mold 100, and drives the positioning column 2 to move to the inside of the outline of the product sheet by external force, so that the edge of the product sheet fits the positioning column 2, and completes the precise positioning. When the upper mold 200 closes downwards, the drive block 3 moves down synchronously with the upper mold 200, triggering the avoidance action of the positioning pin 2 to avoid interfering with the processing operation of the cutting edge insert 101.

[0020] Reference Figure 2 , Figure 3 and Figure 5 The wedge assembly 1 includes a mounting plate 11, which is fixedly mounted on the top of the lower mold 100. A clearance block 12 is slidably mounted on the top of the wedge assembly 1. A mounting cover 13 is fixedly mounted on the top of the mounting plate 11 by screws. A positioning post 2 is fixedly mounted on the side of the clearance block 12 near the cutting edge insert 101. The clearance block 12 is driven to move by the driving block 3. A mating opening 121 is provided on the inner side of the clearance block 12. A through opening A111 is provided on the inner side of the mounting plate 11 corresponding to the mating opening 121. A through opening B131 is provided on the inner side of the mounting cover 13 corresponding to the mating opening 121. A wedge block A122 is fixedly mounted on the inner side of the mating opening 121. A wedge block B31 that mates with the wedge block A122 is provided at the bottom of the driving block 3. A sliding opening A132 is provided on the side of the mounting cover 13 near the cutting edge insert 101. The sliding opening A132 is slidably mounted with the clearance block 12.

[0021] The sliding cavity of the avoidance block 12 is formed by the combination of the mounting plate 11 and the mounting cover 13. The through port A111, the mating port 121 and the through port B131 together provide a channel for the downward movement of the drive block 3. When the upper mold 200 drives the drive block 3 to move downward, the inclined surfaces of the inclined block B31 and the inclined block A122 press against each other. The vertical downward pressure of the drive block 3 is converted into the horizontal lateral thrust of the avoidance block 12 by using the wedge transmission principle. This causes the avoidance block 12 to slide along the sliding port A132 away from the cutting edge insert 101, thereby driving the positioning post 2 to move synchronously to achieve avoidance.

[0022] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6A reset component 14 is provided on the side of the clearance block 12 away from the cut edge insert 101, which is used to drive the clearance block 12 to move for positioning. The reset component 14 includes a screw 141. A threaded hole 123 is provided on the side of the clearance block 12 away from the positioning post 2. The threaded hole 123 is threaded with the screw 141. The mounting cover 13 is provided with a sliding port B133 corresponding to the screw 141. The screw 141 is slidably disposed inside the sliding port B133. A spring 142 is sleeved on the outside of the screw 141. The spring 142 is disposed between the clearance block 12 and the mounting cover 13. A limit plate 1411 is fixedly provided on the side of the screw 141 away from the clearance block 12.

[0023] By rotating the screw 141 in connection with the threaded hole 123, the length of the screw 141 extending into the clearance block 12 can be adjusted, thereby changing the initial compression of the spring 142 to adapt to the positioning requirements of different specifications of product plates. When the clearance block 12 is pushed and slid by the drive block 3, the spring 142 is further compressed and stores elastic potential energy. The limit plate 1411 can prevent the screw 141 from disengaging from the sliding port B133. When the upper mold 200 moves upward after processing is completed, the drive block 3 disengages from the inclined block A122, the spring 142 releases elastic potential energy, pushes the clearance block 12 to slide and reset in the opposite direction along the sliding port A132, and drives the positioning post 2 back to the inside of the product sheet outline, preparing for the next positioning.

[0024] In summary, when using the new energy vehicle rear panel wedge avoidance positioning device disclosed in this application embodiment, the screw 141 is first adjusted according to the specifications of the product sheet to be processed to determine the initial positioning position of the positioning post 2. The product sheet is then placed on the top of the lower mold 100. The positioning post 2 is attached to the edge of the sheet to achieve precise positioning. After the stamping equipment is started, the upper mold 200 moves down. The inclined block B31 of the drive block 3 and the inclined block A122 cooperate to push the avoidance block 12 to drive the positioning post 2 to avoid interference with the cutting edge insert 101's cutting edge processing of the sheet. After processing is completed, the upper mold 200 moves upward, and the spring 142 of the reset component 14 drives the clearance block 12 and the positioning post 2 to reset. The operator can then take out the processed product and proceed to the next processing cycle. The entire device achieves both precise positioning and interference-free processing through the synergistic effect of wedge drive and elastic reset, effectively improving product dimensional consistency and production efficiency.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
